pathconf (sysdeps/unix/sysv/linux/pathconf.c) uses basename. But
pathconf is in POSIX back to 1990 while basename is only reserved with
external linkage in those standards including XPG functions. This
patch fixes this namespace issue in the usual way, renaming basename
to __basename and making it into a weak alias.
Tested for x86_64 and x86 (testsuite, and that disassembly of
installed shared libraries is unchanged by the patch).
[BZ #18444]
* string/basename.c (basename): Rename to __basename and define as
weak alias of __basename. Use libc_hidden_weak.
* include/string.h (__basename): Declare. Use libc_hidden_proto.
* sysdeps/unix/sysv/linux/pathconf.c (distinguish_extX): Call
__basename instead of basename.
* conform/Makefile (test-xfail-POSIX2008/unistd.h/linknamespace):
Remove variable.
(test-xfail-XOPEN2K8/unistd.h/linknamespace): Likewise.
This patch removes the __ASSUME_XFS_RESTRICTED_CHOWN macro, now it can
be presumed to be defined unconditionally. I'm not sure if what's
left of __statfs_chown_restricted is actually useful (if not, a
followup could remove it), but I left it there to keep the patch
conservative and avoid changing the code generated for glibc.
Tested x86_64 that the disassembly of installed shared libraries is
unchanged by the patch.
* sysdeps/unix/sysv/linux/kernel-features.h
(__ASSUME_XFS_RESTRICTED_CHOWN): Remove macro.
* sysdeps/unix/sysv/linux/pathconf.c (__statfs_chown_restricted)
[__ASSUME_XFS_RESTRICTED_CHOWN]: Make code unconditional.
(__statfs_chown_restricted) [!__ASSUME_XFS_RESTRICTED_CHOWN]:
Remove conditional code.
Fix BZ #15305.
On kernel versions earlier than 2.6.29, the Linux kernel exported a
sysctl called restrict_chown for xfs, which could be used to allow
chown to users other than the owner. 2.6.29 removed this support,
causing the open_not_cancel_2 to fail and thus modify errno. The fix
is to save and restore errno so that the caller sees it as unmodified.
Additionally, since the code to check the sysctl is not useful on
newer kernels, we add an ifdef so that in future the code block gets
rmeoved completely.
Fixes BZ #12723
The variable pipe buffer size does nothing to the value of PIPE_BUF,
since the number of bytes that are atomically written is still
PIPE_BUF on Linux.
