* Update x86 fix-fp-int-compare-invalid.h for GCC 8.Joseph Myers2017-10-242-2/+11
| | | | | | | | | | | | | | | | | | The glibc implementation of iseqsig relies on ordered comparison operators raising the "invalid" exception for quiet NaN operands, with a workaround on platforms where a GCC bug means that exception is not raised. For x86, that bug has now been fixed for GCC 8, so this patch disables the workaround in that case. If and when the corresponding bugs for powerpc and s390 are fixed, the headers for those platforms should of course be updated similarly. Tested for x86_64 and x86, including with GCC mainline. Note that other failures appear with GCC mainline because of spurious use of ordered comparison instructions for unordered operations <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82692>. * sysdeps/x86/fpu/fix-fp-int-compare-invalid.h (FIX_COMPARE_INVALID): Define to 0 if [__GNUC_PREREQ (8, 0)].
* posix: Do not use WNOHANG in waitpid call for Linux posix_spawnAdhemerval Zanella2017-10-232-5/+10
| | | | | | | | | | | | | | | | | | | | As shown in some buildbot issues on aarch64 and powerpc, calling clone (VFORK) and waitpid (WNOHANG) does not guarantee the child is ready to be collected. This patch changes the call back to 0 as before fe05e1cb6d64 fix. This change can lead to the scenario 4.3 described in the commit, where the waitpid call can hang undefinitely on the call. However this is also a very unlikely and also undefinied situation where both the caller is trying to terminate a pid before posix_spawn returns and the race pid reuse is triggered. I don't see how to correct handle this specific situation within posix_spawn. Checked on x86_64-linux-gnu, aarch64-linux-gnu and powerpc64-linux-gnu. * sysdeps/unix/sysv/linux/spawni.c (__spawnix): Use 0 instead of WNOHANG in waitpid call.
* aarch64: Document _SC_LEVEL1_DCACHE_LINESIZE caveatSiddhesh Poyarekar2017-10-232-0/+15
| | | | | | | | | | | | | | | | | The _SC_LEVEL1_DCACHE_LINESIZE is reported using the contents of the ctr_el0 register, which tells us the minimum observable cache line size by userspace. This typically is the same as the L1 cache line size, but that may not always be true. It could be a higher level cache line size as long as cache cleaning and invalidation work correctly with that line size in userspace. The falkor core for example reports the L2 line size as the dcache line size in CTR_EL0 while also reporting the correct L1 dcache line size via CCSIDR_EL1. * manual/conf.texi (_SC_LEVEL1_DCACHE_LINESIZE, _SC_LEVEL1_ICACHE_LINESIZE): Document aarch64 caveat.

* PowerPC64 power8 strncpy cfi fixesAlan Modra2017-10-232-13/+19
| | | | | | | | | | | | | | | | | | | | | cfi info for stack adjust needs to be on the insn doing the adjust. cfi describing register saves can be anywhere after the save insn but before the reg is altered. Fewer locations with cfi result in smaller cfi programs and possibly slightly faster exception handling. Thus the LR cfi_offset move. The idea behind ajusting sp after restoring regs is to break a register dependency chain, in this case not be using r1 immediately after it is modified. The missing LR cfi_restore meant that code after the blr, unaligned_lt_16 and other labels, would have cfi that said LR was at cfa+16, but that code is reached without LR being saved. * sysdeps/powerpc/powerpc64/power8/strncpy.S: Move LR cfi.

* Add bits/floatn.h defines for more _FloatN / _FloatNx types.Joseph Myers2017-10-209-1/+316
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bits/floatn.h header currently only has defines relating to _Float128. This patch adds defines relating to other _FloatN / _FloatNx types. The approach taken is to add defines for all _FloatN / _FloatNx types known to GCC, and to put them in a common bits/floatn-common.h header included at the end of all the individual bits/floatn.h headers. If in future some defines become different for different glibc configurations, they will move out into the separate bits/floatn.h headers. Some defines are expected always to be the same across glibc ports. Corresponding defines are nevertheless put in this header. The intent is that where there are conditionals (in headers or in non-installed files) that can just repeat the same or nearly the same logic for each floating-point type, they should do so, even if in fact the cases for some types could be unconditionally present or absent because the same conditionals are true or false for all glibc configurations. This should make the glibc code with such conditionals easier to read, because the reader can just see that the same conditionals are repeated for each type, rather than seeing different conditionals for different types and needing to reason, at each location with such differences, why those differences are indeed correct there. (Cases involving per-format rather than per-type logic are more likely still to need differences in how they handle different types.) Having such defines and conditionals also helps in incremental preparation for adding _Float32 / _Float64 / _Float32x / _Float64x function aliases. I intend subsequent patches to add such conditionals corresponding to those already present for _Float128, as well as making more architecture-specific function implementations use common macros to define aliases in preparation for adding such _FloatN / _FloatNx aliases.

* Avoid build multiarch if compiler warns about mismatched aliasAdhemerval Zanella2017-10-203-6/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 8 emits an warning for alias for functions with incompatible types and it is used extensivelly for ifunc resolvers implementations in C (for instance on weak_alias with the internal symbol name to the external one or with the libc_hidden_def to set ifunc for internal usage). This breaks the build when the ifunc resolver is not defined using gcc attribute extensions (HAVE_GCC_IFUNC being 0). Although for all currently architectures that have multiarch support this compiler options is enabled for default, there is still the option where the user might try build glibc with a compiler without support for such extension. In this case this patch just disable the multiarch folder in sysdeps selections. GCC 7 and before still builds IFUNCs regardless of compiler support (although for the lack of attribute support debug information would be optimal). Checked with a build on multiarch support architectures (aarch64, arm, sparc, s390, powerpc, x86_64, i386) with multiarch enable and disable and with GCC 7 and GCC 8. * configure.ac (libc_cv_gcc_incompatbile_alias): New define: indicates whether compiler emits an warning for alias for functions with incompatible types.
* posix: Fix improper assert in Linux posix_spawn (BZ#22273)Adhemerval Zanella2017-10-202-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted by Florian Weimer, current Linux posix_spawn implementation can trigger an assert if the auxiliary process is terminated before actually setting the err member: 340 /* Child must set args.err to something non-negative - we rely on 341 the parent and child sharing VM. */ 342 args.err = -1; [...] 362 new_pid = CLONE (__spawni_child, STACK (stack, stack_size), stack_size, 363 CLONE_VM | CLONE_VFORK | SIGCHLD, &args); 364 365 if (new_pid > 0) 366 { 367 ec = args.err; 368 assert (ec >= 0); Another possible issue is killing the child between setting the err and actually calling execve. In this case the process will not ran, but posix_spawn also will not report any error: 269 270 args->err = 0; 271 args->exec (args->file, args->argv, args->envp); As suggested by Andreas Schwab, this patch removes the faulty assert and also handles any signal that happens before fork and execve as the spawn was successful (and thus relaying the handling to the caller to figure this out). Different than Florian, I can not see why using atomics to set err would help here, essentially the code runs sequentially (due CLONE_VFORK) and I think it would not be legal the compiler evaluate ec without checking for new_pid result (thus there is no need to compiler barrier). Summarizing the possible scenarios on posix_spawn execution, we have: 1. For default case with a success execution, args.err will be 0, pid will not be collected and it will be reported to caller. 2. For default failure case, args.err will be positive and the it will be collected by the waitpid. An error will be reported to the caller. 3. For the unlikely case where the process was terminated and not collected by a caller signal handler, it will be reported as succeful execution and not be collected by posix_spawn (since args.err will be 0). The caller will need to actually handle this case. 4. For the unlikely case where the process was terminated and collected by caller we have 3 other possible scenarios: 4.1. The auxiliary process was terminated with args.err equal to 0: it will handled as 1. (so it does not matter if we hit the pid reuse race since we won't possible collect an unexpected process). 4.2. The auxiliary process was terminated after execve (due a failure in calling it) and before setting args.err to -1: it will also be handle as 1. but with the issue of not be able to report the caller a possible execve failures. 4.3. The auxiliary process was terminated after args.err is set to -1: this is the case where it will be possible to hit the pid reuse case where we will need to collected the auxiliary pid but we can not be sure if it will be expected one. I think for this case we need to actually change waitpid to use WNOHANG to avoid hanging indefinitely on the call and report an error to caller since we can't differentiate between a default failure as 2. and a possible pid reuse race issue. Checked on x86_64-linux-gnu. * sysdeps/unix/sysv/linux/spawni.c (__spawnix): Handle the case where the auxiliary process is terminated by a signal before calling _exit or execve.
* x86-64: Use fxsave/xsave/xsavec in _dl_runtime_resolve [BZ #21265]H.J. Lu2017-10-209-306/+296

It simplifies _dl_runtime_resolve and supports different calling conventions. ld.so code size is reduced by more than 1 KB. However, use fxsave/xsave/xsavec takes a little bit more cycles than saving and restoring vector and bound registers individually.

This code was added to resolv very early in the development process but does not appear to be an actual test program. The target for building this file is tests but because the glibc Make system is built the way it is, the target is overriden by higher-level tests targets and, therefore, the ga_test program is never built. Removing the target and the source code makes the resolv/Makefile less confusing. Tested by building and running 'make check' on 64 bit host running Kernel 4.10.0-19 configured with --prefix=/home/hawkinsw/code/glibc-build/install --enable-hardcoded-path-in-tests --disable-mathvec Reviewed-by: Carlos O'Donell <carlos@redhat.com>
