Partial backport of:
|
||||
|
||||
commit 7d3db434f910c23591f748a6d0ac3548af1048bb

||||

|
||||
|
||||
Rename and split elf/tst-dlopen-aout collection of tests
|
||||
|
||||
From the beginning, elf/tst-dlopen-aout has exercised two different
|
||||
bugs: (a) failure to report errors for a dlopen of the executable
|
||||
itself in some cases (bug 24900) and (b) incorrect rollback of the
|
||||
TLS modid allocation in case of a dlopen failure (bug 16634).
|
||||
|
||||
This commit replaces the test with elf/tst-dlopen-self for (a) and
|
||||
elf/tst-dlopen-tlsmodid for (b). The latter tests use the
|
||||
elf/tst-dlopen-self binaries (or iconv) with dlopen, so they are
|
||||
no longer self-dlopen tests.
|
||||
|
||||
Tested on x86_64-linux-gnu and i686-linux-gnu, with a toolchain that
|
||||
does not default to PIE.
|
||||
|
||||
Only the non-PIE, non-container test elf/tst-dlopen-tlsmodid is
|
||||
included. The reason is that the self-dlopen fixes and the PIE TLS
|
||||
modid fix have not been backported, and that container testing support
|
||||
is missing downstream. The test binary is adjusted to tst-tls10
|
||||
because tst-dlopen-self does not exist in the backport.
