- tunables: Terminate if end of input is reached (CVE-2023-4911) - - The string parsing routine may end up writing beyond bounds of tunestr - if the input tunable string is malformed, of the form name=name=val. - This gets processed twice, first as name=name=val and next as name=val, - resulting in tunestr being name=name=val:name=val, thus overflowing - tunestr. - - Terminate the parsing loop at the first instance itself so that tunestr - does not overflow. - - This also fixes up tst-env-setuid-tunables to actually handle failures - correct and add new tests to validate the fix for this CVE. - - Signed-off-by: Siddhesh Poyarekar - Reviewed-by: Carlos O'Donell -

In order to facilitate such a - large modification to the dynamic loader, this first patch implements a testing - framework for validating shared object sorting behavior, to enable comparison - between old/new sorting algorithms, and any later enhancements. - - This testing infrastructure consists of a Python script - scripts/dso-ordering-test.py' which takes in a description language, consisting - of strings that describe a set of link dependency relations between DSOs, and - generates testcase programs and Makefile fragments to automatically test the - described situation, for example: - - a->b->c->d # four objects linked one after another - - a->[bc]->d;b->c # a depends on b and c, which both depend on d, - # b depends on c (b,c linked to object a in fixed order) - - a->b->c;{+a;%a;-a} # a, b, c serially dependent, main program uses - # dlopen/dlsym/dlclose on object a - - a->b->c;{}!->[abc] # a, b, c serially dependent; multiple tests generated - # to test all permutations of a, b, c ordering linked - # to main program - - (Above is just a short description of what the script can do, more - documentation is in the script comments.) - - Two files containing several new tests, elf/dso-sort-tests-[12].def are added, - including test scenarios for BZ #15311 and Redhat issue #1162810 [1]. - - Due to the nature of dynamic loader tests, where the sorting behavior and test - output occurs before/after main(), generating testcases to use - support/test-driver.c does not suffice to control meaningful timeout for ld.so. - Therefore a new utility program 'support/test-run-command', based on - test-driver.c/support_test_main.c has been added. This does the same testcase - control, but for a program specified through a command-line rather than at the - source code level. This utility is used to run the dynamic loader testcases - generated by dso-ordering-test.py. - - [1] https://bugzilla.redhat.com/show_bug.cgi?id=1162810 - - Signed-off-by: Chung-Lin Tang -

-+ -+"""Generate testcase files and Makefile fragments for DSO sorting test -+ -+This script takes a small description string language, and generates -+testcases for displaying the ELF dynamic

For names with integer suffixes a range can also be used, -+e.g. (foo1 bar2-5), specifies DSOs foo1, bar2, bar2, bar3, bar4, bar5. -+ -+A {} construct specifies the main test program, and its link dependencies -+are also specified using ->. Inside {}, a few ;-separated constructs are -+allowed: -+ +a Loads module a using dlopen(RTLD_LAZY|RTLD_GLOBAL) -+ ^a Loads module a using dlopen(RTLD_LAZY) -+ %a Use dlsym() to load and call fn_a() -+ @a Calls fn_a() directly. -+ -a Unloads module a using dlclose() -+ -+The generated main program outputs '{' '}' with all output from above -+constructs in between. The other output before/after {} are the ordered -+constructor/destructor output. -+ -+If no {} construct is present, a default empty main program is linked -+against all objects which have no dependency linked to it. e.g. for -+'[ab]->c;d->e', the default main program is equivalent to '{}->[abd]' -+ -+Sometimes for very complex or large testcases, besides specifying a -+few explicit dependencies from main{}, the above default dependency -+behavior is still useful to automatically have, but is turned off -+upon specifying a single explicit {}->dso_name. -+In this case, add {}->* to explicitly add this generation behavior: -+ -+ # Main program links to 'foo', and all other objects which have no -+ # dependency linked to it. -+ {}->foo,{}->* -+ -+Note that '*' works not only on main{}, but can be used as the -+dependency target of any object. Note that it only works as a target, -+not a dependency source. -+ -+The '!' operator after object names turns on permutation of its -+dependencies, e.g. while a->[bcd] only generates one set of objects, -+with 'a.so' built with a link line of "b.so c.so d.so", for a!->[bcd] -+permutations of a's dependencies creates multiple testcases with -+different link line orders: "b.so c.so d.so", "c.so b.so d.so", -+"b.so d.so c.so", etc. Note that for a specified on -+the script command-line, multiple , , etc. -+tests will be generated (e.g. for a!->[bc]!->[de], eight tests with -+different link orders for a, b, and c will be generated) -+ -+It is possible to specify the ELF soname field for an object or the -+main program: -+ # DSO 'a' will be linked with the appropriate -Wl,-soname=x setting -+ a->b->c;soname(a)=x -+ # The the main program can also have a soname specified -+ soname({})=y -+ -+This can be used to test how ld.so behaves when objects and/or the -+main program have such a field set. -+ -+ -+Strings Output by Generated Testcase Programs -+ -+The text output produced by a generated testcase consists of three main -+parts: -+ 1. The constructors' output -+ 2. Output from the main program -+ 3. Destructors' output -+ -+To see by example, a simple test description "a->b->c" generates a testcase -+that when run, outputs: "c>b>a>{}' character, -+and the "c>b>a" part above is the full constructor output by all DSOs, the -+order indicating that DSO 'c', which does not depend on any other DSO, has -+its constructor run first, followed by 'b' and then 'a'. -+ -+Destructor output for each DSO is a '<' character followed by its name, -+reflecting its reverse nature of constructors. In the above example, the -+destructor output part is "g=>h;{+c;%c;-c}->a->h -+ -+This produces a testcase, that when executed outputs: -+ h>a>{+c[g>c>];%c();-c[h dependency as expected. -+Inside the main program, the "+c" action triggers a dlopen() of DSO 'c', -+causing another chain of constructors "g>c>" to be triggered. Here it is -+displayed inside [] brackets for each dlopen call. The same is done for "-c", -+a dlclose() of 'c'. -+ -+The "%c" output is due to calling to fn_c() inside DSO 'c', this comprises -+of two parts: the '%' character is printed by the caller, here it is the main -+program. The 'c' character is printed from inside fn_c(). The '%' character -+indicates that this is called by a dlsym() of "fn_c". A '@' character would -+mean a direct call (with a symbol reference).

A new l_visited:1 - bitfield is added to struct link_map to more elegantly facilitate such a search. - - The DFS algorithm is applied to the input maps[nmap-1] backwards towards - maps[0]. This has the effect of a more "shallow" recursion depth in general - since the input is in BFS. Also, when combined with the natural order of - processing l_initfini[] at each node, this creates a resulting output sorting - closer to the intuitive "left-to-right" order in most cases. - - Another notable implementation adjustment related to this _dl_sort_maps change - is the removing of two char arrays 'used' and 'done' in _dl_close_worker to - represent two per-map attributes. This has been changed to simply use two new - bit-fields l_map_used:1, l_map_done:1 added to struct link_map. This also allows - discarding the clunky 'used' array sorting that _dl_sort_maps had to sometimes - do along the way. - - Tunable support for switching between different sorting algorithms at runtime is - also added.

As a result, if dlopen fails, this could cause a loss of - the NODELETE status of the affected object, eventually resulting - in an incorrect unload. - - Fixes commit f63b73814f74032c0e5d0a83300e3d864ef905e5 ("Remove all - loaded objects if dlopen fails, ignoring NODELETE [BZ #20839]"). - -diff --git a/elf/Makefile b/elf/Makefile -index 467e810e784bb96d..16a3e8dcda19b4ba 100644 ---- a/elf/Makefile -+++ b/elf/Makefile -@@ -185,7 +185,7 @@ tests += restest1 preloadtest loadfail multiload origtest resolvfail \ - tst-audit1 tst-audit2 tst-audit8 tst-audit9 \ - tst-addr1 tst-thrlock \ - tst-unique1 tst-unique2 $(if $(CXX),tst-unique3 tst-unique4 \ -- tst-nodelete) \ -+ tst-nodelete tst-dlopen-nodelete-reloc) \ - tst-initorder tst-initorder2 tst-relsort1 tst-null-argv \ - tst-tlsalign tst-tlsalign-extern tst-nodelete-opened \ - tst-nodelete2 tst-audit11 tst-audit12 tst-dlsym-error tst-noload \ -@@ -266,7 +266,24 @@ modules-names = testobj1 testobj2 testobj3 testobj4 testobj5 testobj6 \ - tst-auditmod9a tst-auditmod9b \ - $(if $(CXX),tst-unique3lib tst-unique3lib2 tst-unique4lib \ - tst-nodelete-uniquemod tst-nodelete-rtldmod \ -- tst-nodelete-zmod) \ -+ tst-nodelete-zmod \ -+ tst-dlopen-nodelete-reloc-mod1 \ -+ tst-dlopen-nodelete-reloc-mod2 \ -+ tst-dlopen-nodelete-reloc-mod3 \ -+ tst-dlopen-nodelete-reloc-mod4 \ -+ tst-dlopen-nodelete-reloc-mod5 \ -+ tst-dlopen-nodelete-reloc-mod6 \ -+ tst-dlopen-nodelete-reloc-mod7 \ -+ tst-dlopen-nodelete-reloc-mod8 \ -+ tst-dlopen-nodelete-reloc-mod9 \ -+ tst-dlopen-nodelete-reloc-mod10 \ -+ tst-dlopen-nodelete-reloc-mod11 \ -+ tst-dlopen-nodelete-reloc-mod12 \ -+ tst-dlopen-nodelete-reloc-mod13 \ -+ tst-dlopen-nodelete-reloc-mod14 \ -+ tst-dlopen-nodelete-reloc-mod15 \ -+ tst-dlopen-nodelete-reloc-mod16 \ -+ tst-dlopen-nodelete-reloc-mod17) \ - tst-initordera1 tst-initorderb1 \ - tst-initordera2 tst-initorderb2 \ - tst-initordera3 tst-initordera4 \ -@@ -1552,3 +1569,48 @@ $(objpfx)tst-dlopenfailmod1.so: \ - $(shared-thread-library) $(objpfx)tst-dlopenfaillinkmod.so - LDFLAGS-tst-dlopenfaillinkmod.so = -Wl,-soname,tst-dlopenfail-missingmod.so - $(objpfx)tst-dlopenfailmod2.so: $(shared-thread-library) -+ -+$(objpfx)tst-dlopen-nodelete-reloc: $(libdl) -+$(objpfx)tst-dlopen-nodelete-reloc.out: \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod1.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod2.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod3.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod4.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod5.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod6.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod7.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod8.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod9.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod10.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod11.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod12.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod13.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod14.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod15.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod16.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod17.so -+tst-dlopen-nodelete-reloc-mod2.so-no-z-defs = yes -+LDFLAGS-tst-dlopen-nodelete-reloc-mod2.so = -Wl,-z,nodelete -+$(objpfx)tst-dlopen-nodelete-reloc-mod4.so: \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod3.so -+LDFLAGS-tst-dlopen-nodelete-reloc-mod4.so = -Wl,--no-as-needed -+$(objpfx)tst-dlopen-nodelete-reloc-mod5.so: \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod4.so -+LDFLAGS-tst-dlopen-nodelete-reloc-mod5.so = -Wl,-z,nodelete,--no-as-needed -+tst-dlopen-nodelete-reloc-mod5.so-no-z-defs = yes -+tst-dlopen-nodelete-reloc-mod7.so-no-z-defs = yes -+$(objpfx)tst-dlopen-nodelete-reloc-mod8.so: $(libdl) -+$(objpfx)tst-dlopen-nodelete-reloc-mod10.so: $(libdl) -+tst-dlopen-nodelete-reloc-mod11.so-no-z-defs = yes -+$(objpfx)tst-dlopen-nodelete-reloc-mod13.so: \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod12.so -+$(objpfx)tst-dlopen-nodelete-reloc-mod15.so: \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod14.so -+tst-dlopen-nodelete-reloc-mod16.so-no-z-defs = yes -+$(objpfx)tst-dlopen-nodelete-reloc-mod16.so: \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod15.so -+LDFLAGS-tst-dlopen-nodelete-reloc-mod16.so = -Wl,--no-as-needed -+$(objpfx)tst-dlopen-nodelete-reloc-mod17.so: \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod15.so \ -+ $(objpfx)tst-dlopen-nodelete-reloc-mod16.so -+LDFLAGS-tst-dlopen-nodelete-reloc-mod17.so = -Wl,--no-as-needed -diff --git a/elf/dl-lookup.c b/elf/dl-lookup.c -index c5e5857fb1fe2808..35a3f96a6296294a 100644 ---- a/elf/dl-lookup.c -+++ b/elf/dl-lookup.c -@@ -311,12 +311,12 @@ do_lookup_unique (const char *undef_name, uint_fast32_t new_hash, - enter_unique_sym (entries, size, - new_hash, strtab + sym->st_name, sym, map);

A complication arises due to recursive - dlopen: After the inner dlopen consumes some space, the pre-allocation - in the outer dlopen may no longer be sufficient. A new member in the - namespace structure, _ns_global_scope_pending_adds keeps track of the - maximum number of objects that need to be added to the global scope. - This enables the inner add_to_global_resize call to take into account - the needs of an outer dlopen. - - Most code in the dynamic linker assumes that the number of global - scope entries fits into an unsigned int (matching the r_nlist member - of struct r_scop_elem).

This is the case in other SysV autofs implementations -and was also the case with Linux autofs. - -But now that /etc/mtab is a symlink to the proc filesystem -mount table the autofs mount entries appear in the mount table -on Linux. - -Prior to the symlinking of /etc/mtab mount table it was -sufficient to call mount(2) and simply not update /etc/mtab -to exclude autofs mounts from mount listings. - -Also, with the symlinking of /etc/mtab we have seen a shift in -usage toward using the proc mount tables directly. - -But the autofs mount entries need to be retained when coming -from the proc file system for applications that need them -(largely autofs file system users themselves) so filtering out -these entries within the kernel itself can't be done. So it -needs be done in user space. - -There are three reasons to omit the autofs mount entries. - -One is that certain types of auto-mounts have an autofs mount -for every entry in their autofs mount map and these maps can -be quite large. This leads to mount table listings containing -a lot of unnecessary entries. - -Also, this change in behaviour between autofs implementations -can cause problems for applications that use getmntent(3) in -other OS implementations as well as Linux. - -Lastly, there's very little that user space can do with autofs -mount entries since this must be left to the autofs mount owner, -typically the automount daemon. But it can also lead to attempts -to access automount managed paths resulting mounts being triggered -when they aren't needed or mounts staying mounted for much longer -thay they need be. While the point of this change ins't to help -with these problems (and it can be quite a problem) it may be -a welcome side effect. - -So the Linux autofs file system has been modified to accept a -pseudo mount option of "ignore" (as is used in other OS -implementations) so that user space can use this as a hint to -skip autofs entries on reading the mount table. - -The Linux autofs automount daemon used getmntent(3) itself and -has been modified to use the proc file system directly so that -it can "ignore" mount option. - -The use of this mount option is opt-in and a configuration -option has been added which defaults to not use this option -so if there are applications that need these entries, other -than autofs itself, they can be retained. Also, since this -filtering is based on an added mount option earlier versions -of Linux autofs iand other autofs file system users will not -use the option and so won't be affected by the change. ---- - -diff --git a/misc/mntent_r.c b/misc/mntent_r.c -index 5d88c45c6f..d90e8d7087 100644 ---- a/misc/mntent_r.c -+++ b/misc/mntent_r.c -@@ -18,6 +18,7 @@ - - #include - #include -+#include - #include - #include - #include -@@ -112,26 +113,18 @@ decode_name (char *buf) - return buf; - } - -- --/* Read one mount table entry from STREAM.

clock_gettime, clock_getres, clock_settime, clock_getcpuclockid, - clock_nanosleep were added to libc, and the file rt/clock-compat.c - was added with forwarders to the actual implementations in libc. - These forwarders were wrapped in - - #if SHLIB_COMPAT (librt, GLIBC_2_2, GLIBC_2_17) - - so that they are not present for newer architectures (such as - powerpc64le) with a 2.17 or later ABI baseline. But the forwarders - were not marked as compatibility symbols. As a result, on older - architectures, historic configure checks such as - - AC_CHECK_LIB(rt, clock_gettime) - - still cause linking against librt, even though this is completely - unnecessary. It also creates a needless porting hazard because - architectures behave differently when it comes to symbol availability. - - Reviewed-by: Carlos O'Donell - -diff --git a/rt/clock-compat.c b/rt/clock-compat.c -index f816973c05c29d5d..11e71aa89019b173 100644 ---- a/rt/clock-compat.c -+++ b/rt/clock-compat.c -@@ -30,14 +30,16 @@ - #if HAVE_IFUNC - # undef INIT_ARCH - # define INIT_ARCH() --# define COMPAT_REDIRECT(name, proto, arglist) libc_ifunc (name, &__##name) -+# define COMPAT_REDIRECT(name, proto, arglist) libc_ifunc (name, &__##name) \ -+ compat_symbol (librt, name, name, GLIBC_2_2); - #else - # define COMPAT_REDIRECT(name, proto, arglist) \ - int \ - name proto \ - { \ - return __##name arglist; \ -- } -+ } \ -+ compat_symbol (librt, name, name, GLIBC_2_2); - #endif - - COMPAT_REDIRECT (clock_getres, diff --git a/glibc-rh1748197-4.patch b/glibc-rh1748197-4.patch deleted file mode 100644 index 795f673..0000000 --- a/glibc-rh1748197-4.patch +++ /dev/null @@ -1,256 +0,0 @@ -commit b06f4c0094d3c68be39ada0ed26ae99d51f48013 -Author: Wilco Dijkstra -Date: Fri Feb 1 12:19:42 2019 +0000 - - Cleanup clock_*time includes - - Clock_gettime, settime and getres implementations are unncessarily - complex due to using defines and C file inclusion.

- Fix alignment of TLS variables for tls variant TLS_TCB_AT_TP [BZ #23403] - - The alignment of TLS variables is wrong if accessed from within a thread - for architectures with tls variant TLS_TCB_AT_TP. - For the main thread the static tls data is properly aligned. - For other threads the alignment depends on the alignment of the thread - pointer as the static tls data is located relative to this pointer. - - This patch adds this alignment for TLS_TCB_AT_TP variants in the same way - as it is already done for TLS_DTV_AT_TP. The thread pointer is also already - properly aligned if the user provides its own stack for the new thread. - - This patch extends the testcase nptl/tst-tls1.c in order to check the - alignment of the tls variables and it adds a pthread_create invocation - with a user provided stack. - The test itself is migrated from test-skeleton.c to test-driver.c - and the missing support functions xpthread_attr_setstack and xposix_memalign - are added. - - ChangeLog: - - [BZ #23403] - * nptl/allocatestack.c (allocate_stack): Align pointer pd for - TLS_TCB_AT_TP tls variant. - * nptl/tst-tls1.c: Migrate to support/test-driver.c. - Add alignment checks. - * support/Makefile (libsupport-routines): Add xposix_memalign and - xpthread_setstack. - * support/support.h: Add xposix_memalign. - * support/xthread.h: Add xpthread_attr_setstack. - * support/xposix_memalign.c: New File. - * support/xpthread_attr_setstack.c: Likewise. - -diff --git a/nptl/allocatestack.c b/nptl/allocatestack.c -index 670cb8ffe6..590350647b 100644 ---- a/nptl/allocatestack.c -+++ b/nptl/allocatestack.c -@@ -572,7 +572,9 @@ allocate_stack (const struct pthread_attr *attr, struct pthread **pdp, - - /* Place the thread descriptor at the end of the stack. */ - #if TLS_TCB_AT_TP -- pd = (struct pthread *) ((char *) mem + size) - 1; -+ pd = (struct pthread *) ((((uintptr_t) mem + size) -+ - TLS_TCB_SIZE) -+ & ~__static_tls_align_m1); - #elif TLS_DTV_AT_TP - pd = (struct pthread *) ((((uintptr_t) mem + size - - __static_tls_size) -diff --git a/nptl/tst-tls1.c b/nptl/tst-tls1.c -index 00489e23e9..1a915224a7 100644 ---- a/nptl/tst-tls1.c -+++ b/nptl/tst-tls1.c -@@ -19,12 +19,16 @@ - #include - #include - #include -- -+#include -+#include -+#include -+#include -+#include - - struct test_s - { -- int a; -- int b; -+ __attribute__ ((aligned(0x20))) int a; -+ __attribute__ ((aligned(0x200))) int b; - }; - - #define INIT_A 1 -@@ -36,15 +40,34 @@ __thread struct test_s s __attribute__ ((tls_model ("initial-exec"))) = - .b = INIT_B - }; - -+/* Use noinline in combination with not static to ensure that the -+ alignment check is really done.

It was also scanning all of the headers included by - our headers, and therefore testing headers we don’t control, e.g. - Linux kernel headers. - - This patch splits the obsolete-typedef test from - scripts/check-installed-headers.sh to a separate program, - scripts/check-obsolete-constructs.py. Being implemented in Python, - it is feasible to make it tokenize C accurately enough to avoid false - positives on the contents of comments and strings. It also only - examines $(headers) in each subdirectory--all the headers we install, - but not any external dependencies of those headers. Headers whose - installed name starts with finclude/ are ignored, on the assumption - that they contain Fortran. - - It is also feasible to make the new test understand the difference - between _defining_ the obsolete typedefs and _using_ the obsolete - typedefs, which means posix/{bits,sys}/types.h no longer need to be - exempted. This uncovered an actual bug in bits/types.h: __quad_t and - __u_quad_t were being used to define __S64_TYPE, __U64_TYPE, - __SQUAD_TYPE and __UQUAD_TYPE. These are changed to __int64_t and - __uint64_t respectively. This is a safe change, despite the comments - in bits/types.h claiming a difference between __quad_t and __int64_t, - because those comments are incorrect. In all current ABIs, both - __quad_t and __int64_t are ‘long’ when ‘long’ is a 64-bit type, and - ‘long long’ when ‘long’ is a 32-bit type, and similarly for __u_quad_t - and __uint64_t. (Changing the types to be what the comments say they - are would be an ABI break, as it affects C++ name mangling.) This - patch includes a minimal change to make the comments not completely - wrong. - - sys/types.h was defining the legacy BSD u_intN_t typedefs using a - construct that was not necessarily consistent with how the C99 uintN_t - typedefs are defined, and is also too complicated for the new script to - understand (it lexes C relatively accurately, but it does not attempt - to expand preprocessor macros, nor does it do any actual parsing). - This patch cuts all of that out and uses bits/types.h's __uintN_t typedefs - to define u_intN_t instead. This is verified to not change the ABI on - any supported architecture, via the c++-types test, which means u_intN_t - and uintN_t were, in fact, consistent on all supported architectures. - - Reviewed-by: Carlos O'Donell - - * scripts/check-obsolete-constructs.py: New test script. - * scripts/check-installed-headers.sh: Remove tests for - obsolete typedefs, superseded by check-obsolete-constructs.py. - * Rules: Run scripts/check-obsolete-constructs.py over $(headers) - as a special test.

(Pseudo-zero and unnormal representations whose unbiased - exponent is less than -1 have already been safely returned from the - function before this point without going through the rest of range - reduction.)

Do this by - splitting the copy up. This may not be required, but matches the - initialization order without dlopen. - - Modify dl_open_worker to relocate the objects in new->l_inifini. - new->l_initfini is constructed in _dl_map_object_deps, and lists the - objects that need initialization and destruction. Originally the list - of objects in new->l_next are relocated. All of these objects should - also be included in new->l_initfini (both lists are populated with - dependencies in _dl_map_object_deps). We can't use new->l_prev to pick - up filtees, as during a recursive dlopen from an interposed malloc - call, l->prev can contain objects that are not ready for relocation. - - Add tests to verify that symbols resolve to the filtee implementation - when auxiliary and filter objects are used, both as a normal link and - when dlopen'd. - - Tested by running the testsuite on x86_64. - -# Conflicts: -# elf/Makefile - -diff --git a/elf/Makefile b/elf/Makefile -index a52d9b1f6a4364a7..b4b618ce62a9e6df 100644 ---- a/elf/Makefile -+++ b/elf/Makefile -@@ -192,7 +192,8 @@ tests += restest1 preloadtest loadfail multiload origtest resolvfail \ - tst-latepthread tst-tls-manydynamic tst-nodelete-dlclose \ - tst-debug1 tst-main1 tst-absolute-sym tst-absolute-zero tst-big-note \ - tst-sonamemove-link tst-sonamemove-dlopen tst-initfinilazyfail \ -- tst-dlopenfail tst-dlopenfail-2 -+ tst-dlopenfail tst-dlopenfail-2 \ -+ tst-filterobj tst-filterobj-dlopen tst-auxobj tst-auxobj-dlopen - # reldep9 - tests-internal += loadtest unload unload2 circleload1 \ - neededtest neededtest2 neededtest3 neededtest4 \ -@@ -302,7 +303,8 @@ modules-names = testobj1 testobj2 testobj3 testobj4 testobj5 testobj6 \ - tst-sonamemove-runmod1 tst-sonamemove-runmod2 \ - tst-initlazyfailmod tst-finilazyfailmod \ - tst-dlopenfailmod1 tst-dlopenfaillinkmod tst-dlopenfailmod2 \ -- tst-dlopenfailmod3 -+ tst-dlopenfailmod3 \ -+ tst-filterobj-flt tst-filterobj-aux tst-filterobj-filtee - - ifeq (yes,$(have-mtls-dialect-gnu2)) - tests += tst-gnu2-tls1 -@@ -1626,3 +1628,15 @@ $(objpfx)tst-dlopen-nodelete-reloc-mod17.so: \ - $(objpfx)tst-dlopen-nodelete-reloc-mod15.so \ - $(objpfx)tst-dlopen-nodelete-reloc-mod16.so - LDFLAGS-tst-dlopen-nodelete-reloc-mod17.so = -Wl,--no-as-needed -+ -+LDFLAGS-tst-filterobj-flt.so = -Wl,--filter=$(objpfx)tst-filterobj-filtee.so -+$(objpfx)tst-filterobj: $(objpfx)tst-filterobj-flt.so -+$(objpfx)tst-filterobj-dlopen: $(libdl) -+$(objpfx)tst-filterobj.out: $(objpfx)tst-filterobj-filtee.so -+$(objpfx)tst-filterobj-dlopen.out: $(objpfx)tst-filterobj-filtee.so -+ -+LDFLAGS-tst-filterobj-aux.so = -Wl,--auxiliary=$(objpfx)tst-filterobj-filtee.so -+$(objpfx)tst-auxobj: $(objpfx)tst-filterobj-aux.so -+$(objpfx)tst-auxobj-dlopen: $(libdl) -+$(objpfx)tst-auxobj.out: $(objpfx)tst-filterobj-filtee.so -+$(objpfx)tst-auxobj-dlopen.out: $(objpfx)tst-filterobj-filtee.so -diff --git a/elf/dl-deps.c b/elf/dl-deps.c -index 9d9b1ba7f244348a..50f053a1586efdc3 100644 ---- a/elf/dl-deps.c -+++ b/elf/dl-deps.c -@@ -485,14 +485,18 @@ _dl_map_object_deps (struct link_map *map, - - map->l_searchlist.r_list = &l_initfini[nlist + 1]; - map->l_searchlist.r_nlist = nlist; -+ unsigned int map_index = UINT_MAX; - - for (nlist = 0, runp = known; runp; runp = runp->next) - { - if (__builtin_expect (trace_mode, 0) && runp->map->l_faked) - /* This can happen when we trace the loading. */ - --map->l_searchlist.r_nlist; -- else -+ else { -+ if (runp->map == map) -+ map_index = nlist; - map->l_searchlist.r_list[nlist++] = runp->map; -+ } - - /* Now clear all the mark bits we set in the objects on the search list - to avoid duplicates, so the next call starts fresh. */ -@@ -550,13 +554,14 @@ Filters not supported with LD_TRACE_PRELINKING")); - } - - /* Maybe we can remove some relocation dependencies now. */ -- assert (map->l_searchlist.r_list[0] == map); - struct link_map_reldeps *l_reldeps = NULL; - if (map->l_reldeps != NULL) - { -- for (i = 1; i < nlist; ++i) -+ for (i = 0; i < nlist; ++i) - map->l_searchlist.r_list[i]->l_reserved = 1; - -+ /* Avoid removing relocation dependencies of the main binary. */ -+ map->l_reserved = 0; - struct link_map **list = &map->l_reldeps->list[0]; - for (i = 0; i < map->l_reldeps->act; ++i) - if (list[i]->l_reserved) -@@ -581,16 +586,30 @@ Filters not supported with LD_TRACE_PRELINKING")); - } - } - -- for (i = 1; i < nlist; ++i) -+ for (i = 0; i < nlist; ++i) - map->l_searchlist.r_list[i]->l_reserved = 0; - } - -- /* Sort the initializer list to take dependencies into account.

IFUNC is always supported, independent of --enable-multi-arch or - --disable-multi-arch. Linker generates IFUNC relocations from input - IFUNC objects and ld.so performs IFUNC relocations. - 2. There are no IFUNC dependencies in ld.so before dynamic relocation - have been performed, - 3.

Copyright issue has been sorted [2] last year. It proposed a new - section (.gnu.xhash) and related dynamic tag (GT_GNU_XHASH). The new - section would be virtually identical to the existing .gnu.hash except - for the translation table (xlat) which would contain correct MIPS - .dynsym indexes corresponding to the hashvals in chains. This is because - MIPS ABI imposes a different ordering of the dynsyms than the one - expected by the .gnu.hash section. Another addition would be a leading - word at the beggining of the section, which would contain the number of - entries in the translation table. - - In this patch, the new section name and dynamic tag are changed to - reflect the fact that the section should be treated as MIPS specific - (.MIPS.xhash and DT_MIPS_XHASH). - - This patch addresses the alignment issue reported in [3] which is caused - by the leading word of the .MIPS.xhash section. Leading word is now - removed in the corresponding binutils patch, and the number of entries - in the translation table is computed using DT_MIPS_SYMTABNO dynamic tag. - - Since the MIPS specific dl-lookup.c file was removed following the - initial patch submission, I opted for the definition of three new macros - in the generic ldsodefs.h. ELF_MACHINE_GNU_HASH_ADDRIDX defines the - index of the dynamic tag in the l_info array. ELF_MACHINE_HASH_SYMIDX is - used to calculate the index of a symbol in GNU hash. On MIPS, it is - defined to look up the symbol index in the translation table. - ELF_MACHINE_XHASH_SETUP is defined for MIPS only. It initializes the - .MIPS.xhash pointer in the link_map_machine struct. - - The other major change is bumping the highest EI_ABIVERSION value for - MIPS to suggest that the dynamic linker now supports GNU hash. - - The patch was tested by running the glibc testsuite for the three MIPS - ABIs (o32, n32 and n64) and for x86_64-linux-gnu. - - [1] https://sourceware.org/ml/binutils/2015-10/msg00057.html - [2] https://sourceware.org/ml/binutils/2018-03/msg00025.html - [3] https://sourceware.org/ml/binutils/2016-01/msg00006.html - - * elf/dl-addr.c (determine_info): Calculate the symbol index - using the newly defined ELF_MACHINE_HASH_SYMIDX macro. - * elf/dl-lookup.c (do_lookup_x): Ditto. - (_dl_setup_hash): Initialize MIPS xhash translation table. - * elf/elf.h (SHT_MIPS_XHASH): New define. - (DT_MIPS_XHASH): New define. - * sysdeps/generic/ldsodefs.h (ELF_MACHINE_GNU_HASH_ADDRIDX): New - define. - (ELF_MACHINE_HASH_SYMIDX): Ditto. - (ELF_MACHINE_XHASH_SETUP): Ditto. - * sysdeps/mips/ldsodefs.h (ELF_MACHINE_GNU_HASH_ADDRIDX): New - define. - (ELF_MACHINE_HASH_SYMIDX): Ditto. - (ELF_MACHINE_XHASH_SETUP): Ditto. - * sysdeps/mips/linkmap.h (struct link_map_machine): New member. - * sysdeps/unix/sysv/linux/mips/ldsodefs.h: Increment valid ABI - version. - * sysdeps/unix/sysv/linux/mips/libc-abis: New ABI version. - -diff --git a/elf/dl-addr.c b/elf/dl-addr.c -index e6c7d020945c51d2..b146fed09a46ff76 100644 ---- a/elf/dl-addr.c -+++ b/elf/dl-addr.c -@@ -42,7 +42,7 @@ determine_info (const ElfW(Addr) addr, struct link_map *match, Dl_info *info, - ElfW(Word) strtabsize = match->l_info[DT_STRSZ]->d_un.d_val;

It is also used in the static - build for initializing parts of the static libc. - - To locate __libc_early_init, a direct symbol lookup function is used, - _dl_lookup_direct. It does not search the entire symbol scope and - consults merely a single link map. This function could also be used - to implement lookups in the vDSO (as an optimization). - - A per-namespace variable (libc_map) is added for locating libc.so, - to avoid repeated traversals of the search scope. It is similar to - GL(dl_initfirst). An alternative would have been to thread a context - argument from _dl_open down to _dl_map_object_from_fd (where libc.so - is identified). This could have avoided the global variable, but - the change would be larger as a result. It would not have been - possible to use this to replace GL(dl_initfirst) because that global - variable is used to pass the function pointer past the stack switch - from dl_main to the main program. Replacing that requires adding - a new argument to _dl_init, which in turn needs changes to the - architecture-specific libc.so startup code written in assembler. - - __libc_early_init should not be used to replace _dl_var_init (as - it exists today on some architectures). Instead, _dl_lookup_direct - should be used to look up a new variable symbol in libc.so, and - that should then be initialized from the dynamic loader, immediately - after the object has been loaded in _dl_map_object_from_fd (before - relocation is run). This way, more IFUNC resolvers which depend on - these variables will work. - - Reviewed-by: Carlos O'Donell - -diff --git a/csu/init-first.c b/csu/init-first.c -index 289373f9d8bd98f4..544229151ef79c67 100644 ---- a/csu/init-first.c -+++ b/csu/init-first.c -@@ -16,7 +16,6 @@ - License along with the GNU C Library; if not, see - . */ - --#include - #include - #include - #include -@@ -80,9 +79,6 @@ _init (int argc, char **argv, char **envp) - - __init_misc (argc, argv, envp); - -- /* Initialize ctype data. */ -- __ctype_init (); -- - #if defined SHARED && !defined NO_CTORS_DTORS_SECTIONS - __libc_global_ctors (); - #endif -diff --git a/csu/libc-start.c b/csu/libc-start.c -index dfbf195328239a17..d9c3248219d8f84f 100644 ---- a/csu/libc-start.c -+++ b/csu/libc-start.c -@@ -22,6 +22,7 @@ - #include - #include - #include -+#include - - #include - -@@ -238,6 +239,10 @@ LIBC_START_MAIN (int (*main) (int, char **, char ** MAIN_AUXVEC_DECL), - __cxa_atexit ((void (*) (void *)) rtld_fini, NULL, NULL); - - #ifndef SHARED -+ /* Perform early initialization.

This change adds three new verbose - messages for potential failure paths. The new messages give - the user the opportunity to use -v and display additional - information about why localedef might be failing. I found - these messages useful myself while writing a localedef - container test for --no-hard-links. - - Since the changes cleanup the code that handle codeset - normalization we add tst-localedef-path-norm which contains - many sub-tests to verify the correct expected normalization of - codeset strings both when installing to default paths (the - only time normalization is enabled) and installing to absolute - paths. During the refactoring I created at least one - buffer-overflow which valgrind caught, but these tests did not - catch because the exec in the container had a very clean heap - with zero-initialized memory. However, between valgrind and - the tests the results are clean. - - The new tst-localedef-path-norm passes without regression on - x86_64. - - Change-Id: I28b9f680711ff00252a2cb15625b774cc58ecb9d - -diff --git a/include/programs/xasprintf.h b/include/programs/xasprintf.h -new file mode 100644 -index 0000000000000000..53193ba3837f7418 ---- /dev/null -+++ b/include/programs/xasprintf.h -@@ -0,0 +1,24 @@ -+/* asprintf with out of memory checking -+ Copyright (C) 2019 Free Software Foundation, Inc. -+ This file is part of the GNU C Library. -+ -+ This program is free software; you can redistribute it and/or modify -+ it under the terms of the GNU General Public License as published -+ by the Free Software Foundation; version 2 of the License, or -+ (at your option) any later version. -+ -+ This program is distributed in the hope that it will be useful, -+ but WITHOUT ANY WARRANTY; without even the implied warranty of -+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The usable features are for correctness and can be exported in - a stable ABI. The preferred features are for performance and only for - glibc internal use. - 2. Change struct cpu_features to - - struct cpu_features - { - struct cpu_features_basic basic; - unsigned int *usable_p; - struct cpuid_registers cpuid[COMMON_CPUID_INDEX_MAX]; - unsigned int usable[USABLE_FEATURE_INDEX_MAX]; - unsigned int preferred[PREFERRED_FEATURE_INDEX_MAX]; - ... - }; - - and initialize usable_p to pointer to the usable arary so that - - struct cpu_features - { - struct cpu_features_basic basic; - unsigned int *usable_p; - struct cpuid_registers cpuid[COMMON_CPUID_INDEX_MAX]; - }; - - can be exported via a stable ABI. The cpuid and usable arrays can be - expanded with backward binary compatibility for both .o and .so files. - 3. Add COMMON_CPUID_INDEX_7_ECX_1 for AVX512_BF16. - 4. Detect ENQCMD, PKS, AVX512_VP2INTERSECT, MD_CLEAR, SERIALIZE, HYBRID, - TSXLDTRK, L1D_FLUSH, CORE_CAPABILITIES and AVX512_BF16. - 5. Rename CAPABILITIES to ARCH_CAPABILITIES. - 6. Check if AVX512_VP2INTERSECT, AVX512_BF16 and PKU are usable. - 7. Update CPU feature detection test. - -diff --git a/sysdeps/unix/sysv/linux/x86_64/64/dl-librecon.h b/sysdeps/unix/sysv/linux/x86_64/64/dl-librecon.h -index ac694c032e7baf87..32f93bb3773a318b 100644 ---- a/sysdeps/unix/sysv/linux/x86_64/64/dl-librecon.h -+++ b/sysdeps/unix/sysv/linux/x86_64/64/dl-librecon.h -@@ -33,7 +33,7 @@ - case 21: \ - if (!__libc_enable_secure \ - && memcmp (envline, "PREFER_MAP_32BIT_EXEC", 21) == 0) \ -- GLRO(dl_x86_cpu_features).feature[index_arch_Prefer_MAP_32BIT_EXEC] \ -+ GLRO(dl_x86_cpu_features).preferred[index_arch_Prefer_MAP_32BIT_EXEC] \ - |= bit_arch_Prefer_MAP_32BIT_EXEC;

Now, while an IS_IN (libm) - conditional could be added to the existing conditionals on such - redirections in include/math.h, the _ISOMAC conditional ought to - suffice (code in other glibc libraries shouldn't be calling floor or - sqrt anyway, as they aren't provided in libc and the other libraries - don't link with libm). But while tests are mostly now built with - _ISOMAC defined, test modules in modules-names aren't unless also - listed in modules-names-tests. - - As far as I can see, all the modules in modules-names in elf/ are in - fact parts of tests and so listing them in modules-names-tests is - appropriate, so they get built with something closer to the headers - used for user code, except in a few cases that actually rely on - something from internal headers.

However we don't want - all surplus TLS to be used for this optimization because dynamically - loaded modules with initial-exec model TLS can only use surplus TLS. - - The new contract for surplus static TLS use is: - - - libc.so can have up to 192 bytes of IE TLS, - - other system libraries together can have up to 144 bytes of IE TLS. - - Some "optional" static TLS is available for opportunistic use. - - The optional TLS is now tunable: rtld.optional_static_tls, so users - can directly affect the allocated static TLS size. (Note that module - unloading with dlclose does not reclaim static TLS. After the optional - TLS runs out, TLS access is no longer optimized to use static TLS.) - - The default setting of rtld.optional_static_tls is 512 so the surplus - TLS is 3*192 + 4*144 + 512 = 1664 by default, the same as before. - - Fixes BZ #25051. - - Tested on aarch64-linux-gnu and x86_64-linux-gnu. - - Reviewed-by: Carlos O'Donell - -Conflicts: - elf/Makefile - (Missing __libc_single_threaded downstream.) - -diff --git a/csu/libc-tls.c b/csu/libc-tls.c -index 6f2a47dc86222407..76aa1b98ea059a43 100644 ---- a/csu/libc-tls.c -+++ b/csu/libc-tls.c -@@ -62,6 +62,9 @@ size_t _dl_tls_static_align; - loaded modules with IE-model TLS or for TLSDESC optimization. - See comments in elf/dl-tls.c where it is initialized. */ - size_t _dl_tls_static_surplus; -+/* Remaining amount of static TLS that may be used for optimizing -+ dynamic TLS access (e.g. with TLSDESC). */ -+size_t _dl_tls_static_optional; - - /* Generation counter for the dtv. */ - size_t _dl_tls_generation; -diff --git a/elf/Makefile b/elf/Makefile -index cbced7605ebe2443..8b96bfefd852b79f 100644 ---- a/elf/Makefile -+++ b/elf/Makefile -@@ -197,7 +197,8 @@ tests += restest1 preloadtest loadfail multiload origtest resolvfail \ - tst-auditmany tst-initfinilazyfail \ - tst-dlopenfail tst-dlopenfail-2 \ - tst-filterobj tst-filterobj-dlopen tst-auxobj tst-auxobj-dlopen \ -- tst-audit14 tst-audit15 tst-audit16 -+ tst-audit14 tst-audit15 tst-audit16 \ -+ tst-tls-ie tst-tls-ie-dlmopen - # reldep9 - tests-internal += loadtest unload unload2 circleload1 \ - neededtest neededtest2 neededtest3 neededtest4 \ -@@ -313,7 +314,10 @@ modules-names = testobj1 testobj2 testobj3 testobj4 testobj5 testobj6 \ - tst-dlopenfailmod1 tst-dlopenfaillinkmod tst-dlopenfailmod2 \ - tst-dlopenfailmod3 \ - tst-filterobj-flt tst-filterobj-aux tst-filterobj-filtee \ -- tst-auditlogmod-1 tst-auditlogmod-2 tst-auditlogmod-3 -+ tst-auditlogmod-1 tst-auditlogmod-2 tst-auditlogmod-3 \ -+ tst-tls-ie-mod0 tst-tls-ie-mod1 tst-tls-ie-mod2 \ -+ tst-tls-ie-mod3 tst-tls-ie-mod4 tst-tls-ie-mod5 \ -+ tst-tls-ie-mod6 - - # Most modules build with _ISOMAC defined, but those filtered out - # depend on internal headers. -@@ -1690,3 +1694,23 @@ $(objpfx)tst-auxobj: $(objpfx)tst-filterobj-aux.so - $(objpfx)tst-auxobj-dlopen: $(libdl) - $(objpfx)tst-auxobj.out: $(objpfx)tst-filterobj-filtee.so - $(objpfx)tst-auxobj-dlopen.out: $(objpfx)tst-filterobj-filtee.so -+ -+$(objpfx)tst-tls-ie: $(libdl) $(shared-thread-library) -+$(objpfx)tst-tls-ie.out: \ -+ $(objpfx)tst-tls-ie-mod0.so \ -+ $(objpfx)tst-tls-ie-mod1.so \ -+ $(objpfx)tst-tls-ie-mod2.so \ -+ $(objpfx)tst-tls-ie-mod3.so \ -+ $(objpfx)tst-tls-ie-mod4.so \ -+ $(objpfx)tst-tls-ie-mod5.so \ -+ $(objpfx)tst-tls-ie-mod6.so -+ -+$(objpfx)tst-tls-ie-dlmopen: $(libdl) $(shared-thread-library) -+$(objpfx)tst-tls-ie-dlmopen.out: \ -+ $(objpfx)tst-tls-ie-mod0.so \ -+ $(objpfx)tst-tls-ie-mod1.so \ -+ $(objpfx)tst-tls-ie-mod2.so \ -+ $(objpfx)tst-tls-ie-mod3.so \ -+ $(objpfx)tst-tls-ie-mod4.so \ -+ $(objpfx)tst-tls-ie-mod5.so \ -+ $(objpfx)tst-tls-ie-mod6.so -diff --git a/elf/dl-reloc.c b/elf/dl-reloc.c -index afeace4d3e49180c..c6139b89d4ecddc8 100644 ---- a/elf/dl-reloc.c -+++ b/elf/dl-reloc.c -@@ -39,13 +39,16 @@ - /* We are trying to perform a static TLS relocation in MAP, but it was - dynamically loaded.

The fork_handler struct has an additional field, 'id', - which is assigned sequentially during registration. Thus, handlers are - executed in ascending order of 'id' during 'prepare', and descending - order of 'id' during parent/child handler execution after the fork. - - Two tests are included: - - * tst-atfork3: Adhemerval Zanella - This test exercises calling dlclose from prepare, parent, and child - handlers. - - * tst-atfork4: This test exercises calling pthread_atfork and dlclose - from the prepare handler. - - [BZ #24595, BZ #27054] - - Co-authored-by: Adhemerval Zanella - Reviewed-by: Adhemerval Zanella - -diff --git a/nptl/Makefile b/nptl/Makefile -index 70a3be23ecfcd9c9..76c914e23e8873f2 100644 ---- a/nptl/Makefile -+++ b/nptl/Makefile -@@ -382,8 +382,17 @@ tests += tst-cancelx2 tst-cancelx3 tst-cancelx4 tst-cancelx5 \ - tst-cancelx16 tst-cancelx17 tst-cancelx18 tst-cancelx20 tst-cancelx21 \ - tst-cleanupx0 tst-cleanupx1 tst-cleanupx2 tst-cleanupx3 tst-cleanupx4 - ifeq ($(build-shared),yes) --tests += tst-atfork2 tst-tls4 tst-_res1 tst-fini1 tst-compat-forwarder \ -- tst-audit-threads -+tests += \ -+ tst-atfork2 \ -+ tst-tls4 \ -+ tst-_res1 \ -+ tst-fini1 \ -+ tst-compat-forwarder \ -+ tst-audit-threads \ -+ tst-atfork3 \ -+ tst-atfork4 \ -+# tests -+ - tests-internal += tst-tls3 tst-tls3-malloc tst-tls5 tst-stackguard1 - tests-nolibpthread += tst-fini1 - ifeq ($(have-z-execstack),yes) -@@ -391,18 +400,39 @@ tests += tst-execstack - endif - endif - --modules-names = tst-atfork2mod tst-tls3mod tst-tls4moda tst-tls4modb \ -- tst-tls5mod tst-tls5moda tst-tls5modb tst-tls5modc \ -- tst-tls5modd tst-tls5mode tst-tls5modf tst-stack4mod \ -- tst-_res1mod1 tst-_res1mod2 tst-execstack-mod tst-fini1mod \ -- tst-join7mod tst-compat-forwarder-mod tst-audit-threads-mod1 \ -- tst-audit-threads-mod2 -+modules-names = \ -+ tst-atfork2mod \ -+ tst-tls3mod \ -+ tst-tls4moda \ -+ tst-tls4modb \ -+ tst-tls5mod \ -+ tst-tls5moda \ -+ tst-tls5modb \ -+ tst-tls5modc \ -+ tst-tls5modd \ -+ tst-tls5mode \ -+ tst-tls5modf \ -+ tst-stack4mod \ -+ tst-_res1mod1 \ -+ tst-_res1mod2 \ -+ tst-execstack-mod \ -+ tst-fini1mod \ -+ tst-join7mod \ -+ tst-compat-forwarder-mod \ -+ tst-audit-threads-mod1 \ -+ tst-audit-threads-mod2 \ -+ tst-atfork3mod \ -+ tst-atfork4mod \ -+# module-names -+ - extra-test-objs += $(addsuffix .os,$(strip $(modules-names))) \ - tst-cleanup4aux.o tst-cleanupx4aux.o - test-extras += tst-cleanup4aux tst-cleanupx4aux - test-modules = $(addprefix $(objpfx),$(addsuffix .so,$(modules-names))) - - tst-atfork2mod.so-no-z-defs = yes -+tst-atfork3mod.so-no-z-defs = yes -+tst-atfork4mod.so-no-z-defs = yes - tst-tls3mod.so-no-z-defs = yes - tst-tls5mod.so-no-z-defs = yes - tst-tls5moda.so-no-z-defs = yes -@@ -541,6 +571,14 @@ LDFLAGS-tst-atfork2 = -rdynamic - tst-atfork2-ENV = MALLOC_TRACE=$(objpfx)tst-atfork2.mtrace - $(objpfx)tst-atfork2mod.so: $(shared-thread-library) - -+$(objpfx)tst-atfork3: $(libdl) $(shared-thread-library) -+LDFLAGS-tst-atfork3 = -rdynamic -+$(objpfx)tst-atfork3mod.so: $(shared-thread-library) -+ -+$(objpfx)tst-atfork4: $(libdl) $(shared-thread-library) -+LDFLAGS-tst-atfork4 = -rdynamic -+$(objpfx)tst-atfork4mod.so: $(shared-thread-library) -+ - tst-stack3-ENV = MALLOC_TRACE=$(objpfx)tst-stack3.mtrace - $(objpfx)tst-stack3-mem.out: $(objpfx)tst-stack3.out - $(common-objpfx)malloc/mtrace $(objpfx)tst-stack3.mtrace > $@; \ -@@ -640,6 +678,8 @@ $(objpfx)../libc.so: $(common-objpfx)libc.so ; - $(addprefix $(objpfx),$(tests-static) $(xtests-static)): $(objpfx)libpthread.a - - $(objpfx)tst-atfork2.out: $(objpfx)tst-atfork2mod.so -+$(objpfx)tst-atfork3.out: $(objpfx)tst-atfork3mod.so -+$(objpfx)tst-atfork4.out: $(objpfx)tst-atfork4mod.so - else - $(addprefix $(objpfx),$(tests) $(test-srcs)): $(objpfx)libpthread.a - endif -diff --git a/nptl/register-atfork.c b/nptl/register-atfork.c -index 9edb7d4bbb49fbed..4c1e20ae8cab005f 100644 ---- a/nptl/register-atfork.c -+++ b/nptl/register-atfork.c -@@ -21,6 +21,8 @@ - #include - #include - #include -+#include -+#include - - #define DYNARRAY_ELEMENT struct fork_handler - #define DYNARRAY_STRUCT fork_handler_list -@@ -29,7 +31,7 @@ - #include - - static struct fork_handler_list fork_handlers; --static bool fork_handler_init = false; -+static uint64_t fork_handler_counter; - - static int atfork_lock = LLL_LOCK_INITIALIZER; - -@@ -39,11 +41,8 @@ __register_atfork (void (*prepare) (void), void (*parent) (void), - { - lll_lock (atfork_lock, LLL_PRIVATE); - -- if (!fork_handler_init) -- { -- fork_handler_list_init (&fork_handlers); -- fork_handler_init = true; -- } -+ if (fork_handler_counter == 0) -+ fork_handler_list_init (&fork_handlers); - - struct fork_handler *newp = fork_handler_list_emplace (&fork_handlers); - if (newp != NULL) -@@ -52,6 +51,13 @@ __register_atfork (void (*prepare) (void), void (*parent) (void), - newp->parent_handler = parent; - newp->child_handler = child; - newp->dso_handle = dso_handle; -+ -+ /* IDs assigned to handlers start at 1 and increment with handler -+ registration.

- aarch64: Added optimized memcpy and memmove for A64FX - - This patch optimizes the performance of memcpy/memmove for A64FX [1] - which implements ARMv8-A SVE and has L1 64KB cache per core and L2 8MB - cache per NUMA node. - - The performance optimization makes use of Scalable Vector Register - with several techniques such as loop unrolling, memory access - alignment, cache zero fill, and software pipelining. - - SVE assembler code for memcpy/memmove is implemented as Vector Length - Agnostic code so theoretically it can be run on any SOC which supports - ARMv8-A SVE standard. - - We confirmed that all testcases have been passed by running 'make - check' and 'make xcheck' not only on A64FX but also on ThunderX2. - - And also we confirmed that the SVE 512 bit vector register performance - is roughly 4 times better than Advanced SIMD 128 bit register and 8 - times better than scalar 64 bit register by running 'make bench'. - - [1] https://github.com/fujitsu/A64FX - - Reviewed-by: Wilco Dijkstra - Reviewed-by: Szabolcs Nagy - -Conflicts: - manual/tunables.texi -

memset for A64FX [1] which - implements ARMv8-A SVE and has L1 64KB cache per core and L2 8MB cache - per NUMA node. - - The performance optimization makes use of Scalable Vector Register - with several techniques such as loop unrolling, memory access - alignment, cache zero fill and prefetch. - - SVE assembler code for memset is implemented as Vector Length Agnostic - code so theoretically it can be run on any SOC which supports ARMv8-A - SVE standard. - - We confirmed that all testcases have been passed by running 'make - check' and 'make xcheck' not only on A64FX but also on ThunderX2. - - And also we confirmed that the SVE 512 bit vector register performance - is roughly 4 times better than Advanced SIMD 128 bit register and 8 - times better than scalar 64 bit register by running 'make bench'. - - [1] https://github.com/fujitsu/A64FX - - Reviewed-by: Wilco Dijkstra - Reviewed-by: Szabolcs Nagy - -Conflicts: - sysdeps/aarch64/multiarch/Makefile -

Take into account first 16B comparison for aligned strings - - The previous version compares the first 16B and increments r4 by the number - of bytes until the address is 16B-aligned, then starts doing aligned loads at - that address. For aligned strings, this causes the first 16B to be compared - twice, because the increment is 0. Here we calculate the next 16B-aligned - address differently, which avoids that issue. - - 2. Use simple comparisons for the first ~192 bytes - - The main loop is good for big strings, but comparing 16B each time is better - for smaller strings. So after aligning the address to 16 Bytes, we check - more 176B in 16B chunks. There may be some overlaps with the main loop for - unaligned strings, but we avoid using the more aggressive strategy too soon, - and also allow the loop to start at a 64B-aligned address. This greatly - benefits smaller strings and avoids overlapping checks if the string is - already aligned at a 64B boundary. - - 3. Reduce dependencies between load blocks caused by address calculation on loop - - Doing a precise time tracing on the code showed many loads in the loop were - stalled waiting for updates to r4 from previous code blocks. This - implementation avoids that as much as possible by using 2 registers (r4 and - r5) to hold addresses to be used by different parts of the code. - - Also, the previous code aligned the address to 16B, then to 64B by doing a - few 48B loops (if needed) until the address was aligned. The main loop could - not start until that 48B loop had finished and r4 was updated with the - current address. Here we calculate the address used by the loop very early, - so it can start sooner. - - The main loop now uses 2 pointers 128B apart to make pointer updates less - frequent, and also unrolls 1 iteration to guarantee there is enough time - between iterations to update the pointers, reducing stalled cycles. - - 4. Use new P10 instructions - - lxvp is used to load 32B with a single instruction, reducing contention in - the load queue. - - vextractbm allows simplifying the tail code for the loop, replacing - vbpermq and avoiding having to generate a permute control vector. - - Reviewed-by: Paul E Murphy - Reviewed-by: Raphael M Zinsly - Reviewed-by: Lucas A.

Magalhaes -Date: Fri Apr 30 18:12:08 2021 -0300 - - powerpc64le: Optimized memmove for POWER10 - - This patch was initially based on the __memmove_power7 with some ideas - from strncpy implementation for Power 9. - - Improvements from __memmove_power7: - - 1. Use lxvl/stxvl for alignment code. - - The code for Power 7 uses branches when the input is not naturally - aligned to the width of a vector. The new implementation uses - lxvl/stxvl instead which reduces pressure on GPRs. It also allows - the removal of branch instructions, implicitly removing branch stalls - and mispredictions. - - 2. Use of lxv/stxv and lxvl/stxvl pair is safe to use on Cache Inhibited - memory. - - On Power 10 vector load and stores are safe to use on CI memory for - addresses unaligned to 16B. This code takes advantage of this to - do unaligned loads. - - The unaligned loads don't have a significant performance impact by - themselves. However doing so decreases register pressure on GPRs - and interdependence stalls on load/store pairs. This also improved - readability as there are now less code paths for different alignments. - Finally this reduces the overall code size. - - 3. Improved performance. - - This version runs on average about 30% better than memmove_power7 - for lengths larger than 8KB. For input lengths shorter than 8KB - the improvement is smaller, it has on average about 17% better - performance. - - This version has a degradation of about 50% for input lengths - in the 0 to 31 bytes range when dest is unaligned. - - Reviewed-by: Tulio Magno Quites Machado Filho - -diff --git a/sysdeps/powerpc/powerpc64/le/power10/memmove.S b/sysdeps/powerpc/powerpc64/le/power10/memmove.S -new file mode 100644 -index 0000000000000000..7dfd57edeb37e8e4 ---- /dev/null -+++ b/sysdeps/powerpc/powerpc64/le/power10/memmove.S -@@ -0,0 +1,320 @@ -+/* Optimized memmove implementation for POWER10. -+ Copyright (C) 2021 Free Software Foundation, Inc. -+ This file is part of the GNU C Library. -+ -+ The GNU C Library is free software; you can redistribute it and/or -+ modify it under the terms of the GNU Lesser General Public -+ License as published by the Free Software Foundation; either -+ version 2.1 of the License, or (at your option) any later version. -+ -+ The GNU C Library is distributed in the hope that it will be useful, -+ but WITHOUT ANY WARRANTY; without even the implied warranty of -+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The same code is used by rawmemchr if the char c - is 0. However, this approach does not work when c != 0. We first need to - subtract each byte by c, so that the value we are looking for is converted to a - 0, then taking the minimum and checking for nulls works again. - - The new code branches after it has compared ~256 bytes and chooses which of the - two strategies above will be used in the main loop, based on the char c. This - extra branch adds some overhead (~5%) for length ~256, but is quickly amortized - by the faster loop for larger sizes. - - Compared to __rawmemchr_power9, this version is ~20% faster for length < 256. - Because of the optimized main loop, the improvement becomes ~35% for c != 0 - and ~50% for c = 0 for strings longer than 256. - - Reviewed-by: Lucas A.

Notice that the - comparison on the main loop will wait for both VSR to be ready. - Therefore aligning one of the input address does not improve - performance. In order to align both registers a vperm is necessary - which add too much overhead. - - 2. Uses new POWER10 instructions - - This code uses lxvp to decrease contention on load by loading 32 bytes - per instruction. - The vextractbm is used to have a smaller tail code for calculating the - return value. - - 3. Performance improvement - - This version has around 35% better performance on average. I saw no - performance regressions for any length or alignment. - - Thanks Matheus for helping me out with some details. - - Co-authored-by: Matheus Castanho - Reviewed-by: Raphael M Zinsly - -diff --git a/sysdeps/powerpc/powerpc64/le/power10/memcmp.S b/sysdeps/powerpc/powerpc64/le/power10/memcmp.S -new file mode 100644 -index 0000000000000000..52f244e7e77cbdf9 ---- /dev/null -+++ b/sysdeps/powerpc/powerpc64/le/power10/memcmp.S -@@ -0,0 +1,179 @@ -+/* Optimized memcmp implementation for POWER10. -+ Copyright (C) 2021 Free Software Foundation, Inc. -+ This file is part of the GNU C Library. -+ -+ The GNU C Library is free software; you can redistribute it and/or -+ modify it under the terms of the GNU Lesser General Public -+ License as published by the Free Software Foundation; either -+ version 2.1 of the License, or (at your option) any later version. -+ -+ The GNU C Library is distributed in the hope that it will be useful, -+ but WITHOUT ANY WARRANTY; without even the implied warranty of -+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Avoiding data races - here without locks would require design changes: the map that is - accessed for static TLS initialization here may be concurrently - freed by dlclose. That use after free may be solved by only - locking around static TLS setup or by ensuring dlclose does not - free modules with static TLS, however currently every link map - with TLS has to be accessed at least to see if it needs static - TLS. And even if that's solved, still a lot of atomics would be - needed to synchronize DTV related globals without a lock. So fix - both bug 19329 and bug 27111 with a lock that prevents DTV setup - running concurrently with dlopen or dlclose. - - _dl_update_slotinfo at TLS access still does not use any locks - so CONCURRENCY NOTES are added to explain the synchronization. - The early exit from the slotinfo walk when max_modid is reached - is not strictly necessary, but does not hurt either. - - An incorrect acquire load was removed from _dl_resize_dtv: it - did not synchronize with any release store or fence and - synchronization is now handled separately at thread creation - and TLS access time. - - There are still a number of racy read accesses to globals that - will be changed to relaxed MO atomics in a followup patch.

- [PATCH] pthread_once hangs when init routine throws an exception [BZ #18435] - - This is another attempt at making pthread_once handle throwing exceptions - from the init routine callback. As the new testcases show, just switching - to the cleanup attribute based cleanup does fix the tst-once5 test, but - breaks the new tst-oncey3 test. That is because when throwing exceptions, - only the unwind info registered cleanups (i.e. C++ destructors or cleanup - attribute), when cancelling threads and there has been unwind info from the - cancellation point up to whatever needs cleanup both unwind info registered - cleanups and THREAD_SETMEM (self, cleanup, ...) registered cleanups are - invoked, but once we hit some frame with no unwind info, only the - THREAD_SETMEM (self, cleanup, ...) registered cleanups are invoked. - So, to stay fully backwards compatible (allow init routines without - unwind info which encounter cancellation points) and handle exception throwing - we actually need to register the pthread_once cleanups in both unwind info - and in the THREAD_SETMEM (self, cleanup, ...) way. - If an exception is thrown, only the former will happen and we in that case - need to also unregister the THREAD_SETMEM (self, cleanup, ...) registered - handler, because otherwise after catching the exception the user code could - call deeper into the stack some cancellation point, get cancelled and then - a stale cleanup handler would clobber stack and probably crash. - If a thread calling init routine is cancelled and unwind info ends before - the pthread_once frame, it will be cleaned up through self->cleanup as - before. And if unwind info is present, unwind_stop first calls the - self->cleanup registered handler for the frame, then it will call the - unwind info registered handler but that will already see __do_it == 0 - and do nothing. - -# Conflicts: -# nptl/Makefile -# (The usual cleanups because they don't match.) -# sysdeps/pthread/Makefile -# (The usual cleanups because all the other tests aren't moved.) - -diff --git a/nptl/Makefile b/nptl/Makefile -index dcf3868869767015..70a3be23ecfcd9c9 100644 ---- a/nptl/Makefile -+++ b/nptl/Makefile -@@ -334,10 +334,6 @@ xtests = tst-setuid1 tst-setuid1-static tst-setuid2 \ - tst-mutexpp1 tst-mutexpp6 tst-mutexpp10 - test-srcs = tst-oddstacklimit - --# Test expected to fail on most targets (except x86_64) due to bug --# 18435 - pthread_once hangs when init routine throws an exception. --test-xfail-tst-once5 = yes -- - # Files which must not be linked with libpthread. - tests-nolibpthread = tst-unload - -diff --git a/nptl/pthreadP.h b/nptl/pthreadP.h -index a2d48b2015cd385c..7ddc166cf32414c4 100644 ---- a/nptl/pthreadP.h -+++ b/nptl/pthreadP.h -@@ -571,6 +571,67 @@ extern void __pthread_cleanup_pop (struct _pthread_cleanup_buffer *buffer, - # undef pthread_cleanup_pop - # define pthread_cleanup_pop(execute) \ - __pthread_cleanup_pop (&_buffer, (execute)); } -+ -+# if defined __EXCEPTIONS && !defined __cplusplus -+/* Structure to hold the cleanup handler information. */ -+struct __pthread_cleanup_combined_frame -+{ -+ void (*__cancel_routine) (void *); -+ void *__cancel_arg; -+ int __do_it; -+ struct _pthread_cleanup_buffer __buffer; -+}; -+ -+/* Special cleanup macros which register cleanup both using -+ __pthread_cleanup_{push,pop} and using cleanup attribute.

Clang (and in future, gcc) make sure that - the -1 case is always safe, i.e. any comparison of the generated - expression with (size_t)-1 is always false so that bit is taken care - of. The rest is avoidable since we want the _chk variant whenever we - have a size expression and it's not -1. - - Rework the conditionals in a uniform way to clearly indicate two - conditions at compile time: - - - Either the size is unknown (-1) or we know at compile time that the - operation length is less than the object size. We can call the - original function in this case. It could be that either the length, - object size or both are non-constant, but the compiler, through - range analysis, is able to fold the *comparison* to a constant. - - - The size and length are known and the compiler can see at compile - time that operation length > object size. This is valid grounds for - a warning at compile time, followed by emitting the _chk variant. - - For everything else, emit the _chk variant. - - This simplifies most of the fortified function implementations and at - the same time, ensures that only one call from _chk or the regular - function is emitted. - - Signed-off-by: Siddhesh Poyarekar - Reviewed-by: Adhemerval Zanella - -diff --git a/io/bits/poll2.h b/io/bits/poll2.h -index f47fd9ad0945234f..6f4dae77e5e2d0d3 100644 ---- a/io/bits/poll2.h -+++ b/io/bits/poll2.h -@@ -35,16 +35,9 @@ extern int __REDIRECT (__poll_chk_warn, (struct pollfd *__fds, nfds_t __nfds, - __fortify_function int - poll (struct pollfd *__fds, nfds_t __nfds, int __timeout) - { -- if (__glibc_objsize (__fds) != (__SIZE_TYPE__) -1) -- { -- if (! __builtin_constant_p (__nfds)) -- return __poll_chk (__fds, __nfds, __timeout, __glibc_objsize (__fds));

The NEON Q registers pushed onto the stack by _dl_runtime_resolve - were twice the size of D registers extracted from the stack frame by - _dl_runtime_profile. - - While 2. might result in wrong information passed on the PLT tracing, - 1. generates wrong runtime behaviour. - - The aarch64 rtld audit support is changed to: - - * Both La_aarch64_regs and La_aarch64_retval are expanded to include - both x8 and the full sized NEON V registers, as defined by the - ABI. - - * dl_runtime_profile needed to extract registers saved by - _dl_runtime_resolve and put them into the new correctly sized - La_aarch64_regs structure. - - * The LAV_CURRENT check is change to only accept new audit modules - to avoid the undefined behavior of not save/restore x8. - - * Different than other architectures, audit modules older than - LAV_CURRENT are rejected (both La_aarch64_regs and La_aarch64_retval - changed their layout and there are no requirements to support multiple - audit interface with the inherent aarch64 issues). - - * A new field is also reserved on both La_aarch64_regs and - La_aarch64_retval to support variant pcs symbols. - - Similar to x86, a new La_aarch64_vector type to represent the NEON - register is added on the La_aarch64_regs (so each type can be accessed - directly). - - Since LAV_CURRENT was already bumped to support bind-now, there is - no need to increase it again. - - Checked on aarch64-linux-gnu. - - Co-authored-by: Adhemerval Zanella - Reviewed-by: Szabolcs Nagy - Reviewed-by: Carlos O'Donell - Tested-by: Carlos O'Donell - -Conflicts: - elf/rtld.c - sysdeps/aarch64/Makefile - Rewrite slightly for inclusion in elf/ testing. - -diff --git a/elf/rtld.c b/elf/rtld.c -index caa980dbda3d1a72..aee5ca357f66121e 100644 ---- a/elf/rtld.c -+++ b/elf/rtld.c -@@ -49,6 +49,7 @@ - #include - #include - #include -+#include - - #include - -@@ -1002,7 +1003,7 @@ file=%s [%lu]; audit interface function la_version returned zero; ignored.\n", - return; - } - -- if (lav > LAV_CURRENT) -+ if (!_dl_audit_check_version (lav)) - { - _dl_debug_printf ("\ - ERROR: audit interface '%s' requires version %d (maximum supported version %d); ignored.\n", -diff --git a/sysdeps/aarch64/Makefile b/sysdeps/aarch64/Makefile -index 3ec78fefc6dd5797..794ea7d13ae2737f 100644 ---- a/sysdeps/aarch64/Makefile -+++ b/sysdeps/aarch64/Makefile -@@ -4,6 +4,26 @@ ifeq ($(subdir),elf) - sysdep-dl-routines += tlsdesc dl-tlsdesc - gen-as-const-headers += dl-link.sym - -+tests += tst-audit26 \ -+ tst-audit27 -+ -+modules-names += \ -+ tst-audit26mod \ -+ tst-auditmod26 \ -+ tst-audit27mod \ -+ tst-auditmod27 -+ -+$(objpfx)tst-audit26: $(objpfx)tst-audit26mod.so \ -+ $(objpfx)tst-auditmod26.so -+LDFLAGS-tst-audit26 += -Wl,-z,lazy -+tst-audit26-ENV = LD_AUDIT=$(objpfx)tst-auditmod26.so -+ -+$(objpfx)tst-audit27: $(objpfx)tst-audit27mod.so \ -+ $(objpfx)tst-auditmod27.so -+$(objpfx)tst-audit27mod.so: $(libsupport) -+LDFLAGS-tst-audit27 += -Wl,-z,lazy -+tst-audit27-ENV = LD_AUDIT=$(objpfx)tst-auditmod27.so -+ - ifeq (yes,$(aarch64-variant-pcs)) - tests += tst-vpcs - modules-names += tst-vpcs-mod -diff --git a/sysdeps/aarch64/bits/link.h b/sysdeps/aarch64/bits/link.h -index 5a7fc1ccd494b2a7..f4f844bfefdaf2f5 100644 ---- a/sysdeps/aarch64/bits/link.h -+++ b/sysdeps/aarch64/bits/link.h -@@ -20,23 +20,31 @@ - # error "Never include directly; use instead." - #endif - -+typedef union -+{ -+ float s; -+ double d; -+ long double q; -+} La_aarch64_vector; -+ - /* Registers for entry into PLT on AArch64. */ - typedef struct La_aarch64_regs - { -- uint64_t lr_xreg[8]; -- uint64_t lr_dreg[8]; -- uint64_t lr_sp; -- uint64_t lr_lr; -+ uint64_t lr_xreg[9]; -+ La_aarch64_vector lr_vreg[8]; -+ uint64_t lr_sp; -+ uint64_t lr_lr; -+ void *lr_vpcs; - } La_aarch64_regs; - - /* Return values for calls from PLT on AArch64. */ - typedef struct La_aarch64_retval - { -- /* Up to two integer registers can be used for a return value. */ -- uint64_t lrv_xreg[2]; -- /* Up to four D registers can be used for a return value. */ -- uint64_t lrv_dreg[4]; -- -+ /* Up to eight integer registers can be used for a return value. */ -+ uint64_t lrv_xreg[8]; -+ /* Up to eight V registers can be used for a return value. */ -+ La_aarch64_vector lrv_vreg[8]; -+ void *lrv_vpcs; - } La_aarch64_retval; - __BEGIN_DECLS - -diff --git a/sysdeps/aarch64/dl-audit-check.h b/sysdeps/aarch64/dl-audit-check.h -new file mode 100644 -index 0000000000000000..e324339a1d4abec3 ---- /dev/null -+++ b/sysdeps/aarch64/dl-audit-check.h -@@ -0,0 +1,28 @@ -+/* rtld-audit version check.

On most targets - this requires moving argv, env and auxv on the stack to ensure correct - stack alignment at the entry point. This had several issues: - - - The code for this adjustment on the stack is written in asm as part - of the target specific ld.so _start code which is hard to maintain. - - - The adjustment is done after _dl_start returns, where it's too late - to update GLRO(dl_auxv), as it is already readonly, so it points to - memory that was clobbered by the adjustment. This is bug 23293. - - - _environ is also wrong in ld.so after the adjustment, but it is - likely not used after _dl_start returns so this is not user visible. - - - _dl_argv was updated, but for this it was moved out of relro, which - changes security properties across targets unnecessarily. - - This patch introduces a generic _dl_start_args_adjust function that - handles the argument adjustments after ld.so processed its own args - and before relro protection is applied. - - The same algorithm is used on all targets, _dl_skip_args is now 0, so - existing target specific adjustment code is no longer used. The bug - affects aarch64, alpha, arc, arm, csky, ia64, nios2, s390-32 and sparc, - other targets don't need the change in principle, only for consistency. - - The GNU Hurd start code relied on _dl_skip_args after dl_main returned, - now it checks directly if args were adjusted and fixes the Hurd startup - data accordingly. - - Follow up patches can remove _dl_skip_args and DL_ARGV_NOT_RELRO. - - Tested on aarch64-linux-gnu and cross tested on i686-gnu. - - Reviewed-by: Adhemerval Zanella - -diff --git a/elf/rtld.c b/elf/rtld.c -index aee5ca357f66121e..22cceeab40319582 100644 ---- a/elf/rtld.c -+++ b/elf/rtld.c -@@ -1127,6 +1127,62 @@ rtld_chain_load (struct link_map *main_map, char *argv0) - rtld_soname, pathname, errcode); - } - -+/* Adjusts the contents of the stack and related globals for the user -+ entry point.

The point is not such - much that awk is problematic for this particular script, as that I'd - like to build up a general Python infrastructure for extracting - information from C headers, for use in writing tests of such headers. - Thus, although this patch does not set up such infrastructure, the - compute_c_consts function in gen-as-const.py might be moved to a - separate Python module in a subsequent patch as a starting point for - such infrastructure. - - The general idea of the code is the same as in the awk version, but no - attempt is made to make the output files textually identical. When - generating a header, a dict of constant names and values is generated - internally then defines are printed in sorted order (rather than the - order in the .sym file, which would have been used before). When - generating a test that the values computed match those from a normal - header inclusion, the test code is made into a compilation test using - _Static_assert, where previously the comparisons were done only when - the test was executed. One fragment of test generation (converting - the previously generated header to use asconst_* prefixes on its macro - names) is still in awk code in the makefiles; only the .sym processing - and subsequent execution of the compiler to extract constants have - moved to the Python script. - - Tested for x86_64, and with build-many-glibcs.py. - - * scripts/gen-as-const.py: New file. - * scripts/gen-as-const.awk: Remove. - * Makerules ($(common-objpfx)%.h $(common-objpfx)%.h.d): Use - gen-as-const.py. - ($(objpfx)test-as-const-%.c): Likewise. - -In the downstream version, scripts/gen-as-const.awk is not removed and -still used in Makerules. - -diff --git a/scripts/gen-as-const.py b/scripts/gen-as-const.py -new file mode 100644 -index 0000000000000000..b7a5744bb192dd67 ---- /dev/null -+++ b/scripts/gen-as-const.py -@@ -0,0 +1,159 @@ -+#!/usr/bin/python3 -+# Produce headers of assembly constants from C expressions. -+# Copyright (C) 2018 Free Software Foundation, Inc. -+# This file is part of the GNU C Library. -+# -+# The GNU C Library is free software; you can redistribute it and/or -+# modify it under the terms of the GNU Lesser General Public -+# License as published by the Free Software Foundation; either -+# version 2.1 of the License, or (at your option) any later version. -+# -+# The GNU C Library is distributed in the hope that it will be useful, -+# but WITHOUT ANY WARRANTY; without even the implied warranty of -+# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

EM_NUM - and PT_NUM are filtered (which was an oversight in the old - conversion). - - The new version of glibcelf should also be compatible with earlier - Python versions because it no longer depends on the enum module and its - advanced features. - - Reviewed-by: Siddhesh Poyarekar - -diff --git a/elf/tst-glibcelf.py b/elf/tst-glibcelf.py -index e5026e2289df206b..a5bff45eae55edea 100644 ---- a/elf/tst-glibcelf.py -+++ b/elf/tst-glibcelf.py -@@ -18,7 +18,6 @@ - # . - - import argparse --import enum - import sys - - import glibcelf -@@ -45,11 +44,57 @@ def find_constant_prefix(name): - - def find_enum_types(): - """A generator for OpenIntEnum and IntFlag classes in glibcelf.""" -+ classes = set((glibcelf._TypedConstant, glibcelf._IntConstant, -+ glibcelf._FlagConstant)) - for obj in vars(glibcelf).values(): -- if isinstance(obj, type) and obj.__bases__[0] in ( -- glibcelf._OpenIntEnum, enum.Enum, enum.IntFlag): -+ if isinstance(obj, type) and obj not in classes \ -+ and obj.__bases__[0] in classes: - yield obj - -+def check_basic(): -+ """Check basic functionality of the constant classes.""" -+ -+ if glibcelf.Pt.PT_NULL is not glibcelf.Pt(0): -+ error('Pt(0) not interned') -+ if glibcelf.Pt(17609) is glibcelf.Pt(17609): -+ error('Pt(17609) unexpectedly interned') -+ if glibcelf.Pt(17609) == glibcelf.Pt(17609): -+ pass -+ else: -+ error('Pt(17609) equality') -+ if glibcelf.Pt(17610) == glibcelf.Pt(17609): -+ error('Pt(17610) equality') -+ -+ if str(glibcelf.Pt.PT_NULL) != 'PT_NULL': -+ error('str(PT_NULL)') -+ if str(glibcelf.Pt(17609)) != '17609': -+ error('str(Pt(17609))') -+ -+ if repr(glibcelf.Pt.PT_NULL) != 'PT_NULL': -+ error('repr(PT_NULL)') -+ if repr(glibcelf.Pt(17609)) != 'Pt(17609)': -+ error('repr(Pt(17609))') -+ -+ if glibcelf.Pt('PT_AARCH64_MEMTAG_MTE') \ -+ is not glibcelf.Pt.PT_AARCH64_MEMTAG_MTE: -+ error('PT_AARCH64_MEMTAG_MTE identity') -+ if glibcelf.Pt(0x70000002) is glibcelf.Pt.PT_AARCH64_MEMTAG_MTE: -+ error('Pt(0x70000002) identity') -+ if glibcelf.PtAARCH64(0x70000002) is not glibcelf.Pt.PT_AARCH64_MEMTAG_MTE: -+ error('PtAARCH64(0x70000002) identity') -+ if glibcelf.Pt.PT_AARCH64_MEMTAG_MTE.short_name != 'AARCH64_MEMTAG_MTE': -+ error('PT_AARCH64_MEMTAG_MTE short name') -+ -+ # Special cases for int-like Shn. -+ if glibcelf.Shn(32) == glibcelf.Shn.SHN_XINDEX: -+ error('Shn(32)') -+ if glibcelf.Shn(32) + 0 != 32: -+ error('Shn(32) + 0') -+ if 32 in glibcelf.Shn: -+ error('32 in Shn') -+ if 0 not in glibcelf.Shn: -+ error('0 not in Shn') -+ - def check_duplicates(): - """Verifies that enum types do not have duplicate values. - -@@ -59,17 +104,16 @@ def check_duplicates(): - global_seen = {} - for typ in find_enum_types(): - seen = {} -- last = None -- for (name, e) in typ.__members__.items(): -+ for (name, e) in typ.by_name.items(): - if e.value in seen: -- error('{} has {}={} and {}={}'.format( -- typ, seen[e.value], e.value, name, e.value)) -- last = e -+ other = seen[e.value] -+ # Value conflicts only count if they are between -+ # the same base type. -+ if e.__class__ is typ and other.__class__ is typ: -+ error('{} has {}={} and {}={}'.format( -+ typ, other, e.value, name, e.value)) - else: - seen[e.value] = name -- if last is not None and last.value > e.value: -- error('{} has {}={} after {}={}'.format( -- typ, name, e.value, last.name, last.value)) - if name in global_seen: - error('{} used in {} and {}'.format( - name, global_seen[name], typ)) -@@ -81,7 +125,7 @@ def check_constant_prefixes(): - seen = set() - for typ in find_enum_types(): - typ_prefix = None -- for val in typ: -+ for val in typ.by_name.values(): - prefix = find_constant_prefix(val.name) - if prefix is None: - error('constant {!r} for {} has unknown prefix'.format( -@@ -113,7 +157,6 @@ def find_elf_h_constants(cc): - # used in . - glibcelf_skipped_aliases = ( - ('EM_ARC_A5', 'EM_ARC_COMPACT'), -- ('PF_PARISC_SBP', 'PF_HP_SBP') - ) - - # Constants that provide little value and are not included in -@@ -146,6 +189,7 @@ DT_VALRNGLO - DT_VERSIONTAGNUM - ELFCLASSNUM - ELFDATANUM -+EM_NUM - ET_HIOS - ET_HIPROC - ET_LOOS -@@ -159,6 +203,7 @@ PT_HISUNW - PT_LOOS - PT_LOPROC - PT_LOSUNW -+PT_NUM - SHF_MASKOS - SHF_MASKPROC - SHN_HIOS -@@ -193,7 +238,7 @@ def check_constant_values(cc): - """Checks the values of constants against glibcelf.""" - - glibcelf_constants = { -- e.name: e for typ in find_enum_types() for e in typ} -+ e.name: e for typ in find_enum_types() for e in typ.by_name.values()} - elf_h_constants = find_elf_h_constants(cc=cc) - - missing_in_glibcelf = (set(elf_h_constants) - set(glibcelf_constants) -@@ -229,12 +274,13 @@ def check_constant_values(cc): - for name in sorted(set(glibcelf_constants) & set(elf_h_constants)): - glibcelf_value = glibcelf_constants[name].value - elf_h_value = int(elf_h_constants[name]) -- # On 32-bit architectures as some constants that are -+ # On 32-bit architectures has some constants that are - # parsed as signed, while they are unsigned in glibcelf.

This patch moves some code from - gen-as-const.py to a new glibcextract.py, which also gains functions - relating to listing macros, and comparing the values of a set of - macros from compiling two different pieces of code. - - It's not just signal numbers that should have such tests; pretty much - any case where glibc copies constants from Linux kernel headers should - have such tests that the values and sets of constants agree except - where differences are known to be OK. Much the same also applies to - structure layouts (although testing those without hardcoding lists of - fields to test will be more complicated). - - Given this patch, another test for a set of macros would essentially - be just a call to glibcextract.compare_macro_consts (plus boilerplate - code - and we could move to having separate text files defining such - tests, like the .sym inputs to gen-as-const, so that only a single - Python script is needed for most such tests). Some such tests would - of course need new features, e.g. where the set of macros changes in - new kernel versions (so you need to allow new macro names on the - kernel side if the kernel headers are newer than the version known to - glibc, and extra macros on the glibc side if the kernel headers are - older). tst-syscall-list.sh could become a Python script that uses - common code to generate lists of macros but does other things with its - own custom logic. - - There are a few differences from the existing shell + awk test. - Because the new test evaluates constants using the compiler, no - special handling is needed any more for one signal name being defined - to another. Because asm/signal.h now needs to pass through the - compiler, not just the preprocessor, stddef.h is included as well - (given the asm/signal.h issue that it requires an externally provided - definition of size_t).

As far as I - can tell, there has been no need (outside the floating-point printf - code, which does its own allocations) for allocations depending on - width or precision since commit - 3e95f6602b226e0de06aaff686dc47b282d7cc16 ("Remove limitation on size - of precision for integers", Sun Sep 12 21:23:32 1999 +0000). Thus, - this patch removes that logic completely, thereby fixing both problems - with excessive allocations for large width and precision for - non-floating-point formats, and the problem with missing overflow - checks with such allocations. Note that this does have the - consequence that width and precision up to INT_MAX are now allowed - where previously INT_MAX / sizeof (CHAR_T) - EXTSIZ or more would have - been rejected, so could potentially expose any other overflows where - the value would previously have been rejected by those removed checks. - - I believe this completely fixes bugs 14231 and 26211. - - Excessive allocations are still possible in the floating-point case - (bug 21127), as are other integer or buffer overflows (see bug 26201). - This does not address the cases where a precision larger than INT_MAX - (embedded in the format string) would be meaningful without printf's - return value overflowing (when it's used with a string format, or %g - without the '#' flag, so the actual output will be much smaller), as - mentioned in bug 17829 comment 8; using size_t internally for - precision to handle that case would be complicated by struct - printf_info being a public ABI. Nor does it address the matter of an - INT_MIN width being negated (bug 17829 comment 7; the same logic - appears a second time in the file as well, in the form of multiplying - by -1). There may be other sources of memory allocations with malloc - in printf functions as well (bug 24988, bug 16060). From inspection, - I think there are also integer overflows in two copies of "if ((width - -= len) < 0)" logic (where width is int, len is size_t and a very long - string could result in spurious padding being output on a 32-bit - system before printf overflows the count of output characters). - - Tested for x86-64 and x86. - - (cherry picked from commit 6caddd34bd7ffb5ac4f36c8e036eee100c2cc535) - -diff --git a/stdio-common/Makefile b/stdio-common/Makefile -index 51062a7dbf698931..d76b47bd5f932f69 100644 ---- a/stdio-common/Makefile -+++ b/stdio-common/Makefile -@@ -64,6 +64,7 @@ tests := tstscanf test_rdwr test-popen tstgetln test-fseek \ - tst-scanf-round \ - tst-renameat2 \ - tst-printf-bz25691 \ -+ tst-vfprintf-width-prec-alloc - - test-srcs = tst-unbputc tst-printf tst-printfsz-islongdouble - -diff --git a/stdio-common/bug22.c b/stdio-common/bug22.c -index b26399acb7dfc775..e12b01731e1b4ac8 100644 ---- a/stdio-common/bug22.c -+++ b/stdio-common/bug22.c -@@ -42,7 +42,7 @@ do_test (void) - - ret = fprintf (fp, "%."

In the wide character case, - grouping is always one wide character, so even with a locale (of which - there aren't any in glibc) grouping every digit, a number would need - to occupy at least 125 wide characters to overflow, and a 64-bit - integer occupies at most 23 characters in octal including a leading 0. - In the narrow character case, the multibyte encoding of the grouping - separator would need to be at least 42 bytes to overflow, again - supposing grouping every digit, but MB_LEN_MAX is 16. So even if we - admit the case of artificially constructed locales not shipped with - glibc, given that such a locale would need to use one of the character - sets supported by glibc, this code cannot be reached at present. (And - POSIX only actually specifies the ' flag for grouping for decimal - output, though glibc acts on it for other bases as well.) - - With binary output (if you consider use of grouping there to be - valid), you'd need a 15-byte multibyte character for overflow; I don't - know if any supported character set has such a character (if, again, - we admit constructed locales using grouping every digit and a grouping - separator chosen to have a multibyte encoding as long as possible, as - well as accepting use of grouping with binary), but given that we have - this code at all (clearly it's not *correct*, or in accordance with - the principle of avoiding arbitrary limits, to skip grouping on - running out of internal space like that), I don't think it should need - any further changes for binary printf support to go in. - - On the other hand, support for large sizes of _BitInt in printf (see - the N2858 proposal) *would* require something to be done about such - arbitrary limits (presumably using dynamic allocation in printf again, - for sufficiently large _BitInt arguments only - currently only - floating-point uses dynamic allocation, and, as previously discussed, - that could actually be replaced by bounded allocation given smarter - code). - - Tested with build-many-glibcs.py for aarch64-linux-gnu (GCC mainline). - Also tested natively for x86_64. - - (cherry picked from commit db6c4935fae6005d46af413b32aa92f4f6059dce) - -diff --git a/stdio-common/vfprintf.c b/stdio-common/vfprintf.c -index 6b83ba91a12cdcd5..2d434ba45a67911e 100644 ---- a/stdio-common/vfprintf.c -+++ b/stdio-common/vfprintf.c -@@ -2101,7 +2101,8 @@ group_number (CHAR_T *front_ptr, CHAR_T *w, CHAR_T *rear_ptr, - copy_rest: - /* No further grouping to be done.
