Remove ia64-linux-gnu

2024-01-08T20:09:36Z

Linux 6.7 removed ia64 from the official tree [1], following the general principle that a glibc port needs upstream support for the architecture in all the components it depends on (binutils, GCC, and the Linux kernel). Apart from the removal of sysdeps/ia64 and sysdeps/unix/sysv/linux/ia64, there are updates to various comments referencing ia64 for which removal of those references seemed appropriate. The configuration is removed from README and build-many-glibcs.py. The CONTRIBUTED-BY, elf/elf.h, manual/contrib.texi (the porting mention), *.po files, config.guess, and longlong.h are not changed. For Linux it allows cleanup some clone2 support on multiple files. The following bug can be closed as WONTFIX: BZ 22634 [2], BZ 14250 [3], BZ 21634 [4], BZ 10163 [5], BZ 16401 [6], and BZ 11585 [7].

wchar: Define va_list for POSIX (BZ #30035)

2023-05-25T19:43:29Z

This was uncovered by a recent clang change [1]. Different than ISO C, POSIX states that va_list should be exported by wchar.h [2]. Checked on x86_64-linux-gnu and aarch64-linux-gnu.

hurd: drop SA_SIGINFO availability xfail

BZ #23089 was fixed by d865ff74ba09 ("hurd: implement SA_SIGINFO signal handlers")

hurd: Add WSTOPPED/WCONTINUED/WEXITED/WNOWAIT support [BZ #23091]

2020-12-28T22:37:04Z

The new __proc_waitid RPC now expects WEXITED to be passed, allowing to properly implement waitid, and thus define the missing W* macros (according to FreeBSD values).

sysvipc: Set ipc_perm mode as mode_t (BZ#18231)

2019-10-10T20:33:27Z

This patch sets the mode field in ipc_perm as mode_t for all architectures, as POSIX specification [1]. The changes required are as follow: 1. It moves the ipc_perm definition out of ipc.h to its own header ipc_perm.h. It also allows consolidate the IPC_* definition on only one header. 2. The generic implementation follow the kernel ipc64_perm size so the syscall can be made directly without temporary buffer copy. However, since glibc defines the MODE field as mode_t, it omits the __PAD1 field (since glibc does not export mode_t as 16-bit for any architecture). It is a two-fold improvement: 2.1. New implementation which follow Linux UAPI will not need to provide an arch-specific ipc-perm.h header neither wrongly use the wrong 16-bit definition from previous default ipc.h (as csky did). 2.1. It allows consolidate ipc_perm definition for architectures that already provide mode_t as 32-bit. 3. All kernel ABIs for the supported architectures already provides the expected padding for mode type extension to 32-bit. However, some architectures the padding has the wrong placement, so it requires the ipc control routines (msgctl, semctl, and shmctl) to adjust the mode field accordingly. Currently they are armeb, microblaze, m68k, s390, and sheb. A new assume is added, __ASSUME_SYSVIPC_BROKEN_MODE_T, which the required ABIs define. 4. For the ABIs that define __ASSUME_SYSVIPC_BROKEN_MODE_T, it also require compat symbols that do not adjust the mode field. Checked on arm-linux-gnueabihf, aarch64-linux-gnu, powerpc64le-linux-gnu, and x86_64-linux-gnu. I also checked the sysvipc tests on hppa-linux-gnu, sh4-linux-gnu, s390x-linux-gnu, and s390-linux-gnu. I also did a sanity test against armeb qemu usermode for the sysvipc tests.

Remove obsolete, never-implemented XSI STREAMS declarations

2019-03-14T14:44:15Z

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 , 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

Replace conformtest.pl with conformtest.py.

2018-11-09T13:54:06Z

Continuing the consolidation on Python for various miscellaneous build and test scripts, this patch moves conformtest from Perl to Python. The substance of the tests run is intended to be the same as before, except that the previous test for tags did not actually achieve the intended purpose of verifying whether a tag was already declared, so is changed to one that would actually fail for a tag that wasn't declared, and a typo in the old test for variables being available ($xyzzy instead of xyzzy) would have made that test not use the correct type (but it would have passed anyway with warnings). No attempt is made to keep the details of what the test output looks like; instead, tests are given names which are made to follow PASS: / FAIL: / XFAIL: / SKIP: / MISSING: as appropriate. In the new version, there is more consistent parsing of test lines (into a series of words, either surrounded by {} or separated by spaces) that applies for all kinds of test lines, rather than the old approach of different regular expressions for every kind of test. A few of the conform/data/ files are adjusted so their syntax works with the new script (which now requires spaces in certain cases where the old script tolerated them being missing, and does not allow stray semicolons at the end of "function" lines). Similarly, common logic is used around what happens with a second subtest if a first one fails (e.g., a test for a symbol's type if the test for availability fails), rather than such logic being replicated separately for each kind of test. Common parsing also applies for test lines both when they are lines for the header under test and when they are lines for another header specified with allow-header, again unlike the old script. Tested for x86_64, and with build-many-glibcs.py. * conform/conformtest.py: New file. * conform/conformtest.pl: Remove. * conform/GlibcConform.pm: Likewise. * conform/glibcconform.py (KEYWORDS_C90): New constant.

conform: XFAIL siginfo_t si_band test on sparc64

We can use long int on sparcv9, but on sparc64, we must match the int type used by the kernel (and not long int, as in POSIX).

nptl: Add C11 threads tss_* functions

2018-07-24T17:07:12Z

This patch adds the tss_* definitions from C11 threads (ISO/IEC 9899:2011), more specifically tss_create, tss_delete, tss_get, tss_set, and required types. Mostly of the definitions are composed based on POSIX conterparts, including tss_t (pthread_key_t). Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, and x86_64-linux-gnu).
