Subject: [PATCH] Properly check stack alignment [BZ #27901]
|
|
||||||
|
|
||||||
1. Replace
|
|
||||||
|
|
||||||
if ((((uintptr_t) &_d) & (__alignof (double) - 1)) != 0)
|
|
||||||
|
|
||||||
which may be optimized out by compiler, with
|
|
||||||
|
|
||||||
int
|
|
||||||
__attribute__ ((weak, noclone, noinline))
|
|
||||||
is_aligned (void *p, int align)
|
|
||||||
{
|
|
||||||
return (((uintptr_t) p) & (align - 1)) != 0;
|
|
||||||
}
|
|
||||||
|
|
||||||
2. Add TEST_STACK_ALIGN_INIT to TEST_STACK_ALIGN.
|
|
||||||
3. Add a common TEST_STACK_ALIGN_INIT to check 16-byte stack alignment
|
|
||||||
for both i386 and x86-64.
|
|
||||||
4. Update powerpc to use TEST_STACK_ALIGN_INIT.

alignment test:
|
|
||||||
|
|
||||||
1. Alpha: Use 0x10000.
|
|
||||||
2. MicroBlaze and Nios II: Use 0x8000.
|
|
||||||
3. All others: Use 0x200000.

Subject: [PATCH 1/4] elf: Properly align PT_LOAD segments [BZ #28676]
|
|
||||||
|
|
||||||
When PT_LOAD segment alignment > the page size, allocate enough space to
|
|
||||||
ensure that the segment can be properly aligned. This change helps code
|
|
||||||
segments use huge pages become simple and available.
|
|
||||||
|
|
||||||
This fixes [BZ #28676].

getcwd: Set errno to ERANGE for size == 1 (CVE-2021-3999)
|
||||||
|
|
||||||
|
No valid path returned by getcwd would fit into 1 byte, so reject the
|
||||||
|
size early and return NULL with errno set to ERANGE. This change is
|
||||||
|
prompted by CVE-2021-3999, which describes a single byte buffer
|
||||||
|
underflow and overflow when all of the following conditions are met:
|
||||||
|
|
||||||
|
- The buffer size (i.e. the second argument of getcwd) is 1 byte
|
||||||
|
- The current working directory is too long
|
||||||
|
- '/' is also mounted on the current working directory
|
||||||
|
|
||||||
|
Sequence of events:
|
||||||
|
|
||||||
|
- In sysdeps/unix/sysv/linux/getcwd.c, the syscall returns ENAMETOOLONG
|
||||||
|
because the linux kernel checks for name length before it checks
|
||||||
|
buffer size
|
||||||
|
|
||||||
|
- The code falls back to the generic getcwd in sysdeps/posix
|
||||||
|
|
||||||
|
- In the generic func, the buf[0] is set to '\0' on line 250
|
||||||
|
|
||||||
|
- this while loop on line 262 is bypassed:
|
||||||
|
|
||||||
|
while (!(thisdev == rootdev && thisino == rootino))
|
||||||
|
|
||||||
|
since the rootfs (/) is bind mounted onto the directory and the flow
|
||||||
|
goes on to line 449, where it puts a '/' in the byte before the
|
||||||
|
buffer.
|
||||||
|
|
||||||
|
- Finally on line 458, it moves 2 bytes (the underflowed byte and the
|
||||||
|
'\0') to the buf[0] and buf[1], resulting in a 1 byte buffer overflow.
|
||||||
|
|
||||||
|
- buf is returned on line 469 and errno is not set.
|
||||||
|
|
||||||
|
This resolves BZ #28769.

support: Add xclone
|

It is a wrapper for Linux clone syscall, to simplify the call to the

|
||||||
|
handling (such as ia64 different name and signature).

aarch64: align stack in clone [BZ #27939]
|
||||||
|
|
||||||
|
The AArch64 PCS requires 16 byte aligned stack. Previously if the
|
||||||
|
caller passed an unaligned stack to clone then the child crashed.
|
||||||
|
|
||||||
|
Fixes bug 27939.

<shlib-compat.h>: Support compat_symbol_reference for _ISOMAC
|
||||||
|
|
||||||

This is helpful for testing compat symbols in cases where _ISOMAC
|
||||||
|
is activated implicitly due to -DMODULE_NAME=testsuite and cannot
|
||||||
|
be disabled easily.
