* time/tst-strftime2.c: Make the file easier to maintainTAMUKI Shoichi2019-04-022-40/+82
| | | | | | | | | | | | | | | | | | | | | | Express the years as full Gregorian years (e.g., 1988 instead of 88) and months with natural numbers (1-12 rather than 0-11). Compare actual dates rather than indexes when selecting the era name. Declare the local variable era as a string character pointer rather than an array of chars where the actual string is copied which might lead to potential buffer overflows in future. Co-authored-by: Rafal Luzynski <digitalfreak@lingonborough.com> Reviewed-by: Carlos O'Donell <carlos@redhat.com> ChangeLog: * time/tst-strftime2.c (date_t): Explicitly define the type.

* Fix strptime era handling, add more strftime tests [BZ #24394]DJ Delorie2019-04-014-3/+473
| | | | | | | | | | | | | | | Test the transition points between all the currently listed Japanese era name changes. This includes testing the transition between the first year date and the second year date. This test will help test the upcoming Japanese era name change. Also fixes a fencepost error where the era name isn't properly parsed by strptime in the last (partial) year of the era. Example: if an era change happens in Feb 1990, and again in Aug 1995, that's 5.5 years long, but the 0.5 year wasn't accounted for. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | The Linux 3.2 clock_getres kernel code (kernel/posix-cpu-timers.c) issued for clock_getres CLOCK_PROCESS_CPUTIME_ID (process_cpu_clock_getres) and CLOCK_THREAD_CPUTIME_ID (thread_cpu_clock_getres) call posix_cpu_clock_getres. And it fails on check_clock only if an invalid clock is used (not the case) or if we pass an invalid the pid/tid in 29 msb of clock_id (not the case either). This patch assumes that clock_getres syscall always support CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID, so there is no need to fallback to hp-timing support for _SC_MONOTONIC_CLOCK neither to issue the syscall to certify the clock_id is supported bt the kernel.

* nptl: Remove pthread_clock_gettime pthread_clock_settimeAdhemerval Zanella2019-03-2218-417/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes CLOCK_THREAD_CPUTIME_ID and CLOCK_PROCESS_CPUTIME_ID support from clock_gettime and clock_settime generic implementation. For Linux, kernel already provides supports through the syscall and Hurd HTL lacks __pthread_clock_gettime and __pthread_clock_settime internal implementation. As described in clock_gettime man-page [1] on 'Historical note for SMP system', implementing CLOCK_{THREAD,PROCESS}_CPUTIME_ID with timer registers is error-prone and susceptible to timing and accurary issues that the libc can not deal without kernel support. This allows removes unused code which, however, still incur in some runtime overhead in thread creation (the struct pthread cpuclock_offset initialization). If hurd eventually wants to support them it should either either implement as a kernel facility (or something related due its architecture) or in system specific implementation.

* Update syscall-names.list for Linux 5.0.Joseph Myers2019-03-152-2/+9
| | | | | | | | | | | | | | | | This patch updates sysdeps/unix/sysv/linux/syscall-names.list for Linux 5.0. Based on testing with build-many-glibcs.py, the only new entry needed is for old_getpagesize (a newly added __NR_* name for an old syscall on ia64). (Because 5.0 changes how syscall tables are handled in the kernel, checking diffs wasn't a useful way of looking for new syscalls in 5.0 as most of the syscall tables were moved to the new representation without actually adding any syscalls to them.) Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/syscall-names.list: Update kernel version to 5.0. (old_getpagesize): New syscall.
* localedata: Add Minguo calendar support to Taiwanese locales [BZ #24293]Felix Yan2019-03-156-0/+29
| | | | | | | | | | | | | | | | | Minguo calendar is the official calendar system, and very widely used in Taiwan. This commit adds its support into glibc. Some background information: The government website (www.gov.tw) uses it, popular public services like Taiwan HSR also use this calendar system. Link to Wikipedia: https://en.wikipedia.org/wiki/Minguo_calendar [BZ #24293] * localedata/locales/zh_TW (era): Add, support Minguo calendar. * localedata/locales/cmn_TW (era): Likewise. * localedata/locales/hak_TW (era): Likewise. * localedata/locales/lzh_TW (era): Likewise. * localedata/locales/nan_TW (era): Likewise.
* malloc: Check for large bin list corruption when inserting unsorted chunkAdam Maris2019-03-141-0/+4
| | | | | | | | Fixes bug 24216. This patch adds security checks for bk and bk_nextsize pointers of chunks in large bin when inserting chunk from unsorted bin. It was possible to write the pointer to victim (newly inserted chunk) to arbitrary memory locations if bk or bk_nextsize pointers of the next large bin chunk got corrupted.
* Remove obsolete, never-implemented XSI STREAMS declarationsFlorian Weimer2019-03-1437-952/+166
| | | | | | | | | | | | | | | | | | | The stub implementations are turned into compat symbols. Linux actually has two reserved system call numbers (for getpmsg and putpmsg), but these system calls have never been implemented, and there are no plans to implement them, so this patch replaces the wrappers with the generic stubs. According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>, the presence of the XSI STREAMS declarations is a minor portability hazard because they are not actually implemented. This commit does not change the TIRPC support code in sunrpc/rpc_svcout.c. It uses additional XTI functionality and therefore never worked with glibc. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
* nss: Fix tst-nss-files-alias-truncated for default --as-needed linkingFlorian Weimer2019-03-143-3/+15
| | | | | | | Linking to the NSS module directly does not work if the linker defaults to --as-needed because it will remove the apparently unused DSO reference and not generate a DT_NEEDED entry. Use an explicit dlopen call, like in the other chroot tests involving NSS modules.
* scripts/check-obsolete-constructs.py: Process all headers as UTF-8.Zack Weinberg2019-03-142-1/+6
| | | | | | | | | | A few of our installed headers contain UTF-8 in comments. check-obsolete-constructs opened files without explicitly specifying their encoding, so it would barf on these headers if “make check” was run in a non-UTF-8 locale. * scripts/check-obsolete-constructs.py (HeaderChecker.check): Specify encoding="utf-8" when opening headers to check.
* Use Linux 5.0 in build-many-glibcs.py.Joseph Myers2019-03-132-3/+11
| | | | | | | | | | | | | | | | | This patch makes build-many-glibcs.py use Linux 5.0 in place of 4.20 (now that the test change required to avoid false positives with ulong in kernel headers has been committed). This includes adjusting the logic to compute a tarball URL to handle different major version numbers (rather than changing the path to hardcode v5.x in place of v4.x, as someone might still wish to check out a v4.x version). Tested that build-many-glibcs.py successfully checks out Linux 5.0 sources after this patch. * scripts/build-many-glibcs.py (Context.checkout): Default Linux version to 5.0. (Context.checkout_tar): Handle variable major version for Linux kernel.

| | | | | | | | | | | | | | inttypes.h and stdint.h are in sysdeps/generic, but there are no other versions of these headers anywhere in the source tree, so they aren’t actually system-dependent. Move them to the subdirectory that installs them (stdlib).

* Use a proper C tokenizer to implement the obsolete typedefs test.Zack Weinberg2019-03-136-63/+516
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test for obsolete typedefs in installed headers was implemented using grep, and could therefore get false positives on e.g. “ulong” in a comment. It was also scanning all of the headers included by our headers, and therefore testing headers we don’t control, e.g. Linux kernel headers. This patch splits the obsolete-typedef test from scripts/check-installed-headers.sh to a separate program, scripts/check-obsolete-constructs.py. Being implemented in Python, it is feasible to make it tokenize C accurately enough to avoid false positives on the contents of comments and strings. It also only examines $(headers) in each subdirectory--all the headers we install, but not any external dependencies of those headers. Headers whose installed name starts with finclude/ are ignored, on the assumption that they contain Fortran. It is also feasible to make the new test understand the difference between _defining_ the obsolete typedefs and _using_ the obsolete typedefs, which means posix/{bits,sys}/types.h no longer need to be exempted. This uncovered an actual bug in bits/types.h: __quad_t and __u_quad_t were being used to define __S64_TYPE, __U64_TYPE, __SQUAD_TYPE and __UQUAD_TYPE. These are changed to __int64_t and __uint64_t respectively. This is a safe change, despite the comments in bits/types.h claiming a difference between __quad_t and __int64_t, because those comments are incorrect. In all current ABIs, both __quad_t and __int64_t are ‘long’ when ‘long’ is a 64-bit type, and ‘long long’ when ‘long’ is a 32-bit type, and similarly for __u_quad_t and __uint64_t. (Changing the types to be what the comments say they are would be an ABI break, as it affects C++ name mangling.) This patch includes a minimal change to make the comments not completely wrong. sys/types.h was defining the legacy BSD u_intN_t typedefs using a construct that was not necessarily consistent with how the C99 uintN_t typedefs are defined, and is also too complicated for the new script to understand (it lexes C relatively accurately, but it does not attempt to expand preprocessor macros, nor does it do any actual parsing). This patch cuts all of that out and uses bits/types.h's __uintN_t typedefs to define u_intN_t instead. This is verified to not change the ABI on any supported architecture, via the c++-types test, which means u_intN_t and uintN_t were, in fact, consistent on all supported architectures.

* Fix output of LD_SHOW_AUXV=1.Stefan Liebler2019-03-137-16/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with commit 1616d034b61622836d3a36af53dcfca7624c844e the output was corrupted on some platforms as _dl_procinfo was called for every auxv entry and on some architectures like s390 all entries were represented as "AT_HWCAP". This patch is removing the condition and let _dl_procinfo decide if an entry is printed in a platform specific or generic way. This patch also adjusts all _dl_procinfo implementations which assumed that they are only called for AT_HWCAP or AT_HWCAP2. They are now just returning a non-zero-value for entries which are not handled platform specifc. ChangeLog: * elf/dl-sysdep.c (_dl_show_auxv): Remove condition and always call _dl_procinfo. * sysdeps/unix/sysv/linux/s390/dl-procinfo.h (_dl_procinfo): Ignore types other than AT_HWCAP. * sysdeps/sparc/dl-procinfo.h (_dl_procinfo): Likewise. * sysdeps/unix/sysv/linux/i386/dl-procinfo.h (_dl_procinfo): Likewise. * sysdeps/powerpc/dl-procinfo.h (_dl_procinfo): Adjust comment in the case of falling back to generic output mechanism. * sysdeps/unix/sysv/linux/arm/dl-procinfo.h (_dl_procinfo): Likewise.
