* stdckdint: use in parse-datetimeHEADmasterPaul Eggert2023-05-171-53/+54

* nstrftime: suggest to glibc how to avoid allocaPaul Eggert2023-05-171-14/+25
| | | | | | | | | * lib/nstrftime.c (widen) [COMPILE_WIDE]: Remove. (__strftime_internal) [COMPILE_WIDE): Instead of converting the multibyte time zone abbreviation into a potentially unbounded alloca buffer, convert it directly into the output buffer. Although this code is not used in Gnulib, this can help the glibc developers avoid the problem on the glibc side.

| | | | | | | | | | | | Problem reported by Ondrej Valousek in: https://lists.gnu.org/r/bug-gnulib/2023-05/msg00078.html * lib/file-has-acl.c: Include minmax.h. [USE_ACL && HAVE_LINUX_XATTR_H && HAVE_LISTXATTR]: Include stdckdint.h. (file_has_acl) [USE_ACL && HAVE_LINUX_XATTR_H && HAVE_LISTXATTR]: If the file has NFSv4 ACLs, ignore any POSIX ACLs, for Fedora 39. Return a bit faster when listxattr returns 0. Don’t loop forever if an attacker is fiddling with ACLs. * modules/file-has-acl (Depends-on): Add minmax, stdckdint.

* timespec: fill in other membersPaul Eggert2023-05-1419-101/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This problem was found when compiling GNU Emacs with --enable-gcc-warnings on a platform where tv_sec is 64 bits and tv_nsec is 32 bits, and struct timespec has padding. GCC -Wuse-of-uninitialized-value complained when a struct timespec initialized only via assigning to tv_sec and tv_nsec was copied via assignment (this was in lib/timespec.h’s make_timespec). Although behavior is well-defined on this platform, the warning is annoying and the behavior might not be well-defined on theoretical platforms where struct timespec has other members. To work around this, initialize all the struct’s members. * lib/getsockopt.c (rpl_getsockopt): * lib/gettime.c (gettime): * lib/gettimeofday.c (gettimeofday): * lib/glthread/thread.c (gl_thread_self): * lib/nanosleep.c (nanosleep): * lib/parse-datetime.y (digits_to_date_time, set_hhmmss) (signed_seconds, unsigned_seconds, yylex, parse_datetime_body): * lib/poll.c (poll): * lib/pselect.c (pselect): * lib/pthread-cond.c (endlessly, pthread_cond_timedwait): * lib/pthread-rwlock.c (pthread_rwlock_timedrdlock) (pthread_rwlock_timedwrlock): * lib/pthread_mutex_timedlock.c (pthread_mutex_timedlock): * lib/select.c (rpl_select): * lib/settime.c (settime): * lib/stat-time.h (get_stat_atime, get_stat_ctime) (get_stat_mtime, get_stat_birthtime): * lib/thrd.c (rpl_thrd_current): * lib/timespec.h (make_timespec): * lib/timespec_getres.c (timespec_getres): * lib/utimecmp.c (utimecmpat): * lib/utimens.c (fdutimens): When filling in a struct timespec or similar time-related structure that might be copied elsewhere, also assign to any storage other than tv_sec and tv_nsec, to avoid undefined behavior on (likely theoretical) platforms where struct timespec has other members, and also to avoid warnings from GCC and/or valgrind.
* stdio: use _GL_ATTRIBUTE_MALLOCPaul Eggert2023-05-131-11/+31
| | | | | | | | | | | | | * lib/stdio.in.h (fdopen, fopen, popen, tmpfile): Declare with _GL_ATTRIBUTE_MALLOC, for consistency with glibc, and so that building the fopen module with ‘gcc -O2 -Wsuggest-attribute=malloc -Wsystem-headers -Werror’ does not fail with “stdio.h: In function ‘rpl_fopen’: stdio.h:970:1: error: function might be candidate for attribute ‘malloc’ [-Werror=suggest-attribute=malloc]”, a problem I noticed on both Fedora 38 and Ubuntu 23.04. sigsegv: Add tentative support for Hurd/x86_64.

| | | | | Fix typo in previous patch, by not accessing freed storage in the unusual case where the statck buffer is not large enough.
* file-has-acl: port to Fedora 39Paul Eggert2023-05-121-27/+67
| | | | | | | | | | | | | | | | | | | | | Fedora 39 getxattr with XATTR_NAME_POSIX_ACL_ACCESS either succeeds or fails with ENODATA, so it is no longer possible to detect from its failure that the filesystem might support NFSv4 ACLs. Problem reported by Ondrej Valousek in: https://lists.gnu.org/r/bug-gnulib/2023-04/msg00228.html Instead, use listxattr to determine whether NFSv4 ACLs are in play. This typically saves syscalls anyway. * lib/file-has-acl.c: In #if, use (HAVE_LINUX_XATTR_H && HAVE_LISTXATTR) instead of GETXATTR_WITH_POSIX_ACLS. The following changes apply when (USE_ACL && HAVE_LINUX_XATTR_H && HAVE_LISTXATTR): Include minmax.h. (have_xattr): New function. (file_has_acl): Try listxattr first; typically this means we need to do no other syscall. Call getxattr only if there are NFSv4 ACLs but not POSIX ACLs. * m4/acl.m4 (gl_FILE_HAS_ACL): Simplify by merely testing for linux/xattr.h and listxattr. All uses changed.
