* iconv: Revert steps array reference counting changesFlorian Weimer2019-07-318-132/+31
| | | | | | | | | | | | | | | The changes introduce a memory leak for gconv steps arrays whose first element is an internal conversion, which has a fixed reference count which is not decremented. As a result, after the change in commit 50ce3eae5ba304650459d4441d7d246a7cefc26f, the steps array is never freed, resulting in an unbounded memory leak. This reverts commit 50ce3eae5ba304650459d4441d7d246a7cefc26f ("gconv: Check reference count in __gconv_release_cache [BZ #24677]") and commit 7e740ab2e7be7d83b75513aa406e0b10875f7f9c ("libio: Fix gconv-related memory leak [BZ #24583]"). It reintroduces bug 24583. (Bug 24677 was just a regression caused by the second commit.)
* Restore r31 setting in powerpc32 swapcontext.Joseph Myers2019-07-302-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit ffe8a9a8318e1db225b22da8bc067408494bac5c, "powerpc: Remove rt_sigreturn usage on context function", removed from powerpc32 swapcontext a setting of r31 that is relied upon in subsequent code. I'm not sure why this didn't produce test failures in Adhemerval's 32-bit testing; in my (soft-float) testing in preparation for 2.30 release, I see several context-related failures FAIL: stdlib/tst-makecontext2 FAIL: stdlib/tst-makecontext3 FAIL: stdlib/tst-setcontext FAIL: stdlib/tst-setcontext2 FAIL: stdlib/tst-setcontext4 FAIL: stdlib/tst-setcontext7 FAIL: stdlib/tst-setcontext9 FAIL: stdlib/tst-swapcontext1 that did not appear in 2.29 testing.

* x86-64: Compile branred.c with -mprefer-vector-width=128 [BZ #24603]H.J. Lu2019-07-244-0/+52

This patch limits vector width to 128 bits to work around this issue. It improves performance of sin and cos by more than 40% on Skylake compiled with -O3 -march=skylake.

* Linux: Use in-tree copy of SO_ constants for !__USE_MISC [BZ #24532]Florian Weimer2019-07-2410-94/+333
| | | | | | | | | | | | | | | | | | | | The kernel changes for a 64-bit time_t on 32-bit architectures resulted in <asm/socket.h> indirectly including <linux/posix_types.h>. The latter is not namespace-clean for the POSIX version of <sys/socket.h>. This issue has persisted across several Linux releases, so this commit creates our own copy of the SO_* definitions for !__USE_MISC mode. The new test socket/tst-socket-consts ensures that the copy is consistent with the kernel definitions (which vary across architectures). The test is tricky to get right because CPPFLAGS includes include/libc-symbols.h, which in turn defines _GNU_SOURCE unconditionally. Tested with build-many-glibcs.py. I verified that a discrepancy in the definitions actually results in a failure of the socket/tst-socket-consts test.

| | | | | | | | | | | | | Whenever a sub-make is created, it inherits the variable subdirs from its parent. This is also true when make check is called with a restricted list of subdirs.

* Afar locales: Months and days updated from CLDR (bug 21897).Rafal Luzynski2019-07-175-12/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit updates month and weekday names (full and abbreviated) from CLDR 35.1 with the following exceptions. It was not clear why the full name of February in aa_DJ and aa_ER was "Kudo" while the abbreviated version is "Nah" but some additional sources [1] [2] as well as the content of aa_ER and aa_ER@saaho suggest it should be "Naharsi Kudo". This commit consequently sets the translation of February to "Naharsi Kudo" in aa_DJ and aa_ET. aa_ER@saaho is not supported by CLDR but since the month names were identical to aa_ER before this commit, the same values have been copied from aa_ER.

* posix: Fix large mmap64 offset for mips64n32 (BZ#24699)Adhemerval Zanella2019-07-105-5/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | The fix for BZ#21270 (commit 158d5fa0e19) added a mask to avoid offset larger than 1^44 to be used along __NR_mmap2. However mips64n32 users __NR_mmap, as mips64n64, but still defines off_t as old non-LFS type (other ILP32, such x32, defines off_t being equal to off64_t). This leads to use the same mask meant only for __NR_mmap2 call for __NR_mmap, thus limiting the maximum offset it can use with mmap64. This patch fixes by setting the high mask only for __NR_mmap2 usage. The posix/tst-mmap-offset.c already tests it and also fails for mips64n32. The patch also change the test to check for an arch-specific header that defines the maximum supported offset. Checked on x86_64-linux-gnu, i686-linux-gnu, and I also tests tst-mmap-offset on qemu simulated mips64 with kernel 3.2.0 kernel for both mips-linux-gnu and mips64-n32-linux-gnu. [BZ #24699] * posix/tst-mmap-offset.c: Mention BZ #24699. (do_test_bz21270): Rename to do_test_large_offset and use mmap64_maximum_offset to check for maximum expected offset value. * sysdeps/generic/mmap_info.h: New file. * sysdeps/unix/sysv/linux/mips/mmap_info.h: Likewise. * sysdeps/unix/sysv/linux/mmap64.c (MMAP_OFF_HIGH_MASK): Define iff __NR_mmap2 is used.
* nss_db: fix endent wrt NULL mappings [BZ #24695] [BZ #24696]DJ Delorie2019-07-1011-2/+189
| | | | | | | | | | | | | nss_db allows for getpwent et al to be called without a set*ent, but it only works once. After the last get*ent a set*ent is required to restart, because the end*ent did not properly reset the module. Resetting it to NULL allows for a proper restart. If the database doesn't exist, however, end*ent erroniously called munmap which set errno. The test case runs "makedb" inside the testroot, so needs selinux DSOs installed.
