wordexp: handle overflow in positional parameter number (bug 28011)

2021-07-23T17:08:25+00:00

Use strtoul instead of atoi so that overflow can be detected.

posix: Sync gnulib regex implementation

2021-07-22T21:08:33+00:00

This patch syncs the regex implementation with gnulib (commit 0ee5212).
Only two changes in GLIBC regex testing are required:

  1. posix/bug-regex28.c: as previously discussed [1] the change of
     expected results on the pattern should be safe.

  2. posix/PCRE.tests: the ERE (a)|\1 is malformed (in the sense that
     the \1 doesn't mean anything) and although current GLIBC accepts
     it has undefined behavior.  This patch removes the specific test.

This sync contains some patches from thread 'Regex: Make libc regex
more usable outside GLIBC.' [2] which have been pushed upstream in
gnulib.  This patches also fixes some regex issues (BZ #23233,
BZ #21163, BZ #18986, BZ #13762) and I did not add testcases for
both #23233 and #13762 because I couldn't think a simple way to
trigger the expected failure path to trigger them.

Checked on x86_64-linux-gnu and i686-linux-gnu.

Fix use-after-free in glob when expanding ~user (bug 25414)

2021-07-22T20:09:57+00:00

The value of `end_name' points into the value of `dirname', thus don't
deallocate the latter before the last use of the former.

Revert "Comment out second appearances of symbols in version scripts, lld errors out instead of just warning"

2019-10-22T17:46:06+00:00

This reverts commit 0eee22b49ee34d852e79c6b65598b72f504ccebd.

It appears lld no longer throws an error with these duplicated symbols.

This completes the deprecation and removal of this inclusion, which
was begun in the 2.25 release.

	* posix/sys/types.h: Don't include sys/sysmacros.h.

Fix posix/tst-glob_lstat_compat on alpha [BZ #22818]

2018-05-31T18:39:12+00:00

The tst-glob_lstat_compat test needs to run tests on the previous
version of glob. On alpha, there are three versions of glob, GLIBC_2.0,
GLIBC_2.1 and GLIBC_2.27, while on other architectures there are only
the GLIBC_2.0 and GLIBC_2.27 version. Therefore on alpha the previous
version is GLIBC_2.1 and not GLIBC_2.0.

Changelog:
	[BZ #22818]
	* posix/tst-glob_lstat_compat.c [__alpha__] (glob): Access
	the GLIBC_2.1 version.
