* Fix strtod overflow detection (bug 23279).Joseph Myers2018-06-136-4391/+4864
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As shown by bug 23279, strtod's round_and_return has an off-by-one error in its overflow detection, only counting an exponent greater than MAX_EXP as overflowing when an exponent of MAX_EXP also means overflow (recall the ISO C definition of DBL_MAX_EXP etc. is based on a floating-point model where 2^exp is multiplied by a value in the interval [0.5, 1), so 2^MAX_EXP is not representable). For decimal arguments to strtod, a separate overflow check in the main implementation covers the case where the integer part of the argument (truncated to the nearest integer towards zero) has more than MAX_EXP bits, meaning that this issue in round_and_return only affects cases (arguments with absolute value strictly between the maximum representable value and 2^MAX_EXP) where overflow depends on the rounding mode; in such cases, the returned value would still have been correct on overflow but without the overflow exception being raised or errno being set to ERANGE. For hex float arguments, however, other cases can arise, as shown in bug 23279, where a value with exponent already set to MAX_EXP is passed into round_and_return and a result can wrongly end up being NaN, or infinity instead of the largest finite value. This patch fixes the off-by-one error, adds testing of overflow exceptions to the tst-strtod-round framework, and adds tests of these issues. Tested for x86_64. Also ran the tst-strtod-round tests for powerpc to make sure the new tests didn't introduce any new failures for IBM long double. [BZ #23279] * stdlib/strtod_l.c (round_and_return): Handle an exponent of MAX_EXP as overflowing. * stdlib/gen-tst-strtod-round.c (string_to_fp): Clear MPFR overflow flag.

* Fix comments in _dl_dst_count and _dl_dst_substitute.Carlos O'Donell2018-06-122-6/+11
| | | | | | | | | The comments in _dl_dst_count is adjusted to match what the code does which is count DSTs from the start of the string. With the removal of DL_DST_COUNT we no longer accept an input that starts at the first $. In _dl_dst_substitute we adjust the comment to indicate that both conditions must be true for the SUID/SGID $ORIGIN exception.
* Fix fallback path in __pthread_mutex_timedlock ().Carlos O'Donell2018-06-122-1/+6
| | | | | | | Fix the typo in the fallback path in __pthread_mutex_timedlock () whic hcalls lll_futex_timed_wait (). This is only useful for cases where the patch is being backported to older distributions where only lll_futex_timed_wait () is available.
* Do not use const attribute for nan functions (bug 23277).Joseph Myers2018-06-124-2/+45
| | | | | | | | | | | | | | | | | | | | | As in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86113 for __builtin_nan, bits/mathcalls.h wrongly declares the nan function with the __const__ attribute. Because the function reads memory pointed to by an argument, it's only pure, not const. This patch removes the incorrect attribute and adds a testcase for the bug. No __pure__ attribute is added to replace the incorrect __const__ one, since that would introduce problems when using GCC versions that have the incorrect built-in __const__ attribute and warn for the combination of those two attributes. Tested for x86_64. [BZ #23277] * math/bits/mathcalls.h [__USE_ISOC99] (nan): Do not use __const__ attribute. * math/test-nan-const.c: New file. * math/Makefile (tests): Add test-nan-const.

| | | | | | | | | | | | | On x86-64, there may be multiple IFUNC implementations for a given function. But we may be only interested in a subset of them. This patch adds -f/--functions argument to compare a subset of IFUNC implementations. * benchtests/scripts/compare_strings.py (process_results): Add funcs argument. Compare only functions which are selected. (main): Check if base function is among selected functions. Pass selected functions to process_results. (__main__): Add -f/--functions argument.

* Improve DST handling (Bug 23102, Bug 21942, Bug 18018, Bug 23259).Carlos O'Donell2018-06-125-93/+165
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit improves DST handling significantly in the following ways: firstly is_dst () is overhauled to correctly process DST sequences that would be accepted given the ELF gABI. This means that we actually now accept slightly more sequences than before. Now we accept $ORIGIN$ORIGIN, but in the past we accepted only $ORIGIN\0 or $ORIGIN/..., but this kind of behaviour results in unexpected and uninterpreted DST sequences being used as literal search paths leading to security defects. Therefore the first step in correcting this defect is making is_dst () properly account for all DSTs and making the function context free in the sense that it counts DSTs without knowledge of path, or AT_SECURE. Next, _dl_dst_count () is also simplified to count all DSTs regardless of context. Then in _dl_dst_substitute () we reintroduce context-dependent processing for such things as AT_SECURE handling. At the level of _dl_dst_substitute we can have access to things like the true start of the string sequence to validate $ORIGIN-based paths rooted in trusted directories. Lastly, we tighten up the accepted sequences in AT_SECURE, and avoid leaving known unexpanded DSTs, this is noted in the NEWS entry. Verified with a sequence of 68 tests on x86_64 that cover non-AT_SECURE and AT_SECURE testing using a sysroot (requires root to run). The tests cover cases for bug 23102, bug 21942, bug 18018, and bug 23259. These tests are not yet appropriate for the glibc regression testsuite, but with the upcoming test-in-container testing framework it should be possible to include these tests upstream soon. See the mailing list for the tests: https://www.sourceware.org/ml/libc-alpha/2018-06/msg00251.html
* Avoid cancellable I/O primitives in ld.so.Zack Weinberg2018-06-1245-279/+647
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Neither the <dlfcn.h> entry points, nor lazy symbol resolution, nor initial shared library load-up, are cancellation points, so ld.so should exclusively use I/O primitives that are not cancellable. We currently achieve this by having the cancellation hooks compile as no-ops when IS_IN(rtld); this patch changes to using exclusively _nocancel primitives in the source code instead, which makes the intent clearer and significantly reduces the amount of code compiled under IS_IN(rtld) as well as IS_IN(libc) -- in particular, elf/Makefile no longer thinks we require a copy of unwind.c in rtld-libc.a. (The older mechanism is preserved as a backstop.) The bulk of the change is splitting up the files that define the _nocancel I/O functions, so they don't also define the variants that *are* cancellation points; after which, the existing logic for picking out the bits of libc that need to be recompiled as part of ld.so Just Works. I did this for all of the _nocancel functions, not just the ones used by ld.so, for consistency. fcntl was a little tricky because it's only a cancellation point for certain opcodes (F_SETLKW(64), which can block), and the existing __fcntl_nocancel wasn't applying the FCNTL_ADJUST_CMD hook, which strikes me as asking for trouble, especially as the only nontrivial definition of FCNTL_ADJUST_CMD (for powerpc64) changes F_*LK* opcodes. To fix this, fcntl_common moves to fcntl_nocancel.c along with __fcntl_nocancel, and changes its name to the extern (but hidden) symbol __fcntl_nocancel_adjusted, so that regular fcntl can continue calling it. __fcntl_nocancel now applies FCNTL_ADJUST_CMD; so that both both fcntl.c and fcntl_nocancel.c can see it, the only nontrivial definition moves from sysdeps/u/s/l/powerpc/powerpc64/fcntl.c to .../powerpc64/sysdep.h and becomes entirely a macro, instead of a macro that calls an inline function. The nptl version of libpthread also changes a little, because its "compat-routines" formerly included files that defined all the _nocancel functions it uses; instead of continuing to duplicate them, I exported the relevant ones from libc.so as GLIBC_PRIVATE. Since the Linux fcntl.c calls a function defined by fcntl_nocancel.c, it can no longer be used from libpthread.so; instead, introduce a custom forwarder, pt-fcntl.c, and export __libc_fcntl from libc.so as GLIBC_PRIVATE. The nios2-linux ABI doesn't include a copy of vfork() in libpthread, and it was handling that by manipulating libpthread-routines in .../linux/nios2/Makefile; it is cleaner to do what other such ports do, and have a pt-vfork.S that defines no symbols. Right now, it appears that Hurd does not implement _nocancel I/O, so sysdeps/generic/not-cancel.h will forward everything back to the regular functions. This changed the names of some of the functions that sysdeps/mach/hurd/dl-sysdep.c needs to interpose. * elf/dl-load.c, elf/dl-misc.c, elf/dl-profile.c, elf/rtld.c * sysdeps/unix/sysv/linux/dl-sysdep.c Include not-cancel.h.

| | | | | | | | | | | | | | | | | | | As reported in bug 23272, the ldbl-96 implementation of fma (fma for double, in terms of ldbl-96 as the internal arithmetic type, as used on 32-bit x86) is missing some of the special-case handling for non-finite arguments, resulting in incorrect NaN results when the first two arguments are infinities, the third is finite and so the infinities go through the logic for finite arguments.

* posix: Fix posix_spawnp to not execute invalid binaries in non compat mode ↵Adhemerval Zanella2018-06-088-11/+175
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (BZ#23264) Current posix_spawnp implementation wrongly tries to execute invalid binaries (for instance script without shebang) as a shell script in non compat mode. It was a regression introduced by 9ff72da471a509a8c19791efe469f47fa6977410 when __spawni started to use __execvpe instead of __execve (glibc __execvpe try to execute ENOEXEC as shell script regardless). This patch fixes it by using an internal symbol (__execvpex) with the faulty semantic (since compat mode is handled by spawni.c itself). It was reported by Daniel Drake on libc-help [1].

* Update kernel version in syscall-names.list to 4.17.Joseph Myers2018-06-052-2/+7
| | | | | | | | | | | As far as I can tell, Linux 4.17 does not add any new syscalls; this patch updates the version number in syscall-names.list to reflect that it's still current for 4.17.

* x86-64: Optimize strcmp/wcscmp and strncmp/wcsncmp with AVX2Leonardo Sandoval2018-06-0114-2/+1033
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimize x86-64 strcmp/wcscmp and strncmp/wcsncmp with AVX2. It uses vector comparison as much as possible. Peak performance observed on a SkyLake machine: 9x, 3x, 2.5x and 5.5x for strcmp, strncmp, wcscmp and wcsncmp, respectively. The larger the comparison length, the more benefit using avx2 functions, except on the strcmp, where peak is observed at length == 32 bytes. Select AVX2 strcmp/wcscmp on AVX2 machines where vzeroupper is preferred and AVX unaligned load is fast. NB: It uses TZCNT instead of BSF since TZCNT produces the same result as BSF for non-zero input. TZCNT is faster than BSF and is executed as BSF if machine doesn't support TZCNT. * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add strcmp-avx2, strncmp-avx2, wcscmp-avx2, wcscmp-sse2, wcsncmp-avx2 and wcsncmp-sse2. * sysdeps/x86_64/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add tests for __strcmp_avx2, __strncmp_avx2, __wcscmp_avx2, __wcsncmp_avx2, __wcscmp_sse2 and __wcsncmp_sse2. * sysdeps/x86_64/multiarch/strcmp.c (OPTIMIZE (avx2)): (IFUNC_SELECTOR): Return OPTIMIZE (avx2) on AVX 2 machines if AVX unaligned load is fast and vzeroupper is preferred. * sysdeps/x86_64/multiarch/strncmp.c: Likewise. * sysdeps/x86_64/multiarch/strcmp-avx2.S: New file. * sysdeps/x86_64/multiarch/strncmp-avx2.S: Likewise. * sysdeps/x86_64/multiarch/wcscmp-avx2.S: Likewise. * sysdeps/x86_64/multiarch/wcscmp-sse2.S: Likewise. * sysdeps/x86_64/multiarch/wcscmp.c: Likewise. * sysdeps/x86_64/multiarch/wcsncmp-avx2.S: Likewise. * sysdeps/x86_64/multiarch/wcsncmp-sse2.c: Likewise. * sysdeps/x86_64/multiarch/wcsncmp.c: Likewise. * sysdeps/x86_64/wcscmp.S (__wcscmp): Add alias only if __wcscmp is undefined.

* Make powerpc-nofpu __sqrtsf2, __sqrtdf2 compat symbols (bug 18473).Joseph Myers2018-06-017-54/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | powerpc-nofpu libc exports __sqrtsf2 and __sqrtdf2 symbols. The export of these soft-fp symbols is a mistake; they aren't part of the libgcc interface and GCC will never generate code that calls them. This patch makes them into compat symbols (no code built for static libc), moving their sources from the generic soft-fp sources to sysdeps/powerpc/nofpu (the underlying soft-fp FP_SQRT functionality remains of use to implement actual sqrt public interfaces, such as sqrtl / sqrtf128 for which it is used on various platforms, but __sqrt[sdt]f2 are not such interfaces). Tested with build-many-glibcs.py for relevant platforms. [BZ #18473] * soft-fp/sqrttf2.c: Remove file. * soft-fp/sqrtdf2.c: Move to .... * sysdeps/powerpc/nofpu/sqrtdf2.c: ... here. Include <shlib-compat.h>. (__sqrtdf2): Make conditional on [SHLIB_COMPAT (libc, GLIBC_2_3_2, GLIBC_2_28)].

* libio: Avoid _allocate_buffer, _free_buffer function pointers [BZ #23236]Florian Weimer2018-06-018-32/+49
| | | | | | | | | | | | | These unmangled function pointers reside on the heap and could be targeted by exploit writers, effectively bypassing libio vtable validation. Instead, we ignore these pointers and always call malloc or free. In theory, this is a backwards-incompatible change, but using the global heap instead of the user-supplied callback functions should have little application impact. (The old libstdc++ implementation exposed this functionality via a public, undocumented constructor in its strstreambuf class.)

* Remove sysdeps/sparc/sparc64/soft-fp directory.Joseph Myers2018-05-2535-121/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per <https://sourceware.org/ml/libc-alpha/2014-10/msg00369.html>, there should not be separate sysdeps/<arch>/soft-fp directories when those are used by all configurations that use sysdeps/<arch>, and, more generally, should not be sysdeps/foo/Implies files pointing to a subdirectory foo/bar. This patch eliminates the sysdeps/sparc/sparc64/soft-fp directory accordingly, merging its contents into sysdeps/sparc/sparc64. This completes removing the unnecessary <arch>/soft-fp sysdeps directories. sysdeps/sparc/sparc64/soft-fp/e_ilogbl.c is removed rather than moved. It was not in fact used previously - the ldbl-128 version of e_ilogbl.c was used instead - and moving it into sysdeps/sparc/sparc64 results in it being used, but causing a build failure because of FP_DECL_EX declaring an unused variable (as I noted in <https://sourceware.org/ml/libc-alpha/2013-10/msg00457.html> that file doesn't appear to use FP_DECL_EX). Given that the file was previously unused and so presumably not tested recently, removing it is the safe way to avoid this patch changing what actually gets built into glibc (if this file should turn out more efficient than the ldbl-128 e_ilogbl.c, it can always be added back in future with the build failure fixed).

Gomes <gabriel@inconstante.eti.br> Date: Fri Nov 3 10:44:36 2017 -0200 Provide a C++ version of iseqsig (bug 22377) mistakenly used double parameters in the long double version of iseqsig, thus causing spurious conversions to double, as reported on bug 23171. Tested for powerpc64le and x86_64.

* Remove sysdeps/sh/soft-fp directory.Joseph Myers2018-05-233-1/+6
| | | | | | | | | | | | | | | | As per <https://sourceware.org/ml/libc-alpha/2014-10/msg00369.html>, there should not be separate sysdeps/<arch>/soft-fp directories when those are used by all configurations that use sysdeps/<arch>, and, more generally, should not be sysdeps/foo/Implies files pointing to a subdirectory foo/bar. This patch eliminates the sysdeps/sh/soft-fp directory accordingly, merging its contents into sysdeps/sh. Tested with build-many-glibcs.py that installed stripped shared libraries for sh configurations are unchanged by this patch. * sysdeps/sh/Implies: Remove sh/soft-fp. * sysdeps/sh/soft-fp/sfp-machine.h: Move to .... * sysdeps/sh/sfp-machine.h: ... here.
* x86-64: Skip zero length in __mem[pcpy|move|set]_ermsH.J. Lu2018-05-233-0/+19
| | | | | | | | | | | | | This patch skips zero length in __mempcpy_erms, __memmove_erms and __memset_erms. Tested on x86-64. * sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S (__mempcpy_erms): Skip zero length. (__memmove_erms): Likewise. * sysdeps/x86_64/multiarch/memset-vec-unaligned-erms.S (__memset_erms): Likewise.
