* [Bug 15368] Move pthread_kill to libc and use it to implement raise.zack/wip-pthread-no-dupe-defnsZack Weinberg2018-03-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fix for bug #15368 was unnecessarily Linux-specific. To recap, POSIX specifies raise to be async-signal-safe, but also specifies it to be equivalent to pthread_kill(pthread_self(), sig), which is not an async-signal-safe sequence of operations; a signal handler could run in between pthread_self and pthread_kill, and do something (such as calling fork, which is also async-signal-safe) that would invalidate the thread descriptor. This is even true in the hypothetical case of a port that doesn't implement multithreading: kill(getpid(), sig) will fire the signal twice if a signal handler runs in between, calls fork, and then returns on both sides of the fork. I don't see anything in the standards to forbid that. The Linux-specific fix was to override the definitions of raise in both libpthread and libc to the same unitary function that blocks signals, retrieves TID and PID directly from the kernel, calls tgkill, and only then unblocks signals. This patch generalizes that to any port: pthread_kill is moved from libpthread to libc, with a forwarding stub left behind. The definition of raise in libpthread is also replaced with a forwarding stub. The Linux-specific definition of raise is deleted; those ports will now use sysdeps/pthread/raise.c, which blocks signals first, then calls pthread_self and pthread_kill, and then unblocks signals. Similarly, sysdeps/posix/raise.c (which would be used on a port that didn't implement multithreading) blocks signals, calls getpid and kill, and then unblocks signals. Thus, ports need only implement the primitives correctly and do not need to worry about making raise async-signal-safe. The only wrinkle was that up till now, we did not bother initializing the ->tid field of the initial thread's descriptor unless libpthread was loaded; now that raise calls pthread_kill even in a single- threaded environment, that won't fly. This is abstractly easy to fix; the tricky part was figuring out _where_ to put the calls (two of them, as it happens) to __pthread_initialize_pids, and I'd appreciate careful eyes on those changes. You might be wondering why it's safe to rely on the TID in the thread descriptor, rather than calling gettid directly. Since all signals are blocked from before calling pthread_self until after pthread_kill uses the TID to call tgkill, the question is whether some _other_ thread could do something that would invalidate the calling thread's descriptor, and I believe there is no such thing. While I was at it I fixed another bug: raise was returning an error code on failure (like pthread_kill does) instead of setting errno as specified. This is user-visible but I don't think it's worth recording as a fixed bug, nobody bothers checking whether raise failed anyway. * nptl/pt-raise.c * sysdeps/unix/sysv/linux/pt-raise.c * sysdeps/unix/sysv/linux/raise.c: Remove file. * sysdeps/unix/sysv/linux/pthread_kill.c: Use __is_internal_signal to check for forbidden signals.

Provide __libc_raise, with raise as strong alias, libc_hidden_def for raise, and gsignal as weak alias. * sysdeps/pthread/raise.c: New file. Implement by blocking signals, calling pthread_self and pthread_kill, and then unblocking signals again. Provide same symbols as above. * sysdeps/generic/internal-signals.h: Define all of the same functions that sysdeps/unix/sysv/linux/internal-signals.h does, with sensible default definitions. * sysdeps/unix/sysv/linux/internal-signals.h: Clarify comments. * nptl/pthread_kill.c: Define __libc_pthread_kill, with __pthread_kill as strong alias and pthread_kill as weak alias. * nptl/pthread_self.c: Define __pthread_self, with pthread_self as weak alias. * signal/raise.c: Define __libc_raise, with raise as strong alias, libc_hidden_def for raise, and gsignal as weak alias. * nptl/Makefile: Move pthread_kill from libpthread-routines to routines.

As discussed for the build infrastructure patch, tgmath.h support is deliberately deferred, and FP_FAST_* macros are not applicable without optimized function implementations. Function implementations are added for all relevant pairs of formats (including certain cases of a format and itself where more than one type has that format). The main implementations use round-to-odd, or a trivial computation in the case where both formats are the same or where the wider format is IBM long double (in which case we don't attempt to be correctly rounding). The sysdeps/ieee754/soft-fp implementations use soft-fp, and are used automatically for configurations without exceptions and rounding modes by virtue of existing Implies files. As previously discussed, optimized versions for particular architectures are possible, but not included. i386 gets a special version of f32xaddf64 to avoid problems with double rounding (similar to the existing fdim version), since this function must round just once without an intermediate rounding to long double. (No such special version is needed for any other function, because the nontrivial functions use round-to-odd, which does the intermediate computation with the rounding mode set to round-to-zero, and double rounding is OK except in round-to-nearest mode, so is OK for that intermediate round-to-zero computation.) mul and div will need slightly different special versions for i386 (using round-to-odd on long double instead of precision control) because of the possibility of inexact intermediate results in the subnormal range for double. To reduce duplication among the different function implementations, math-narrow.h gets macros CHECK_NARROW_ADD, NARROW_ADD_ROUND_TO_ODD and NARROW_ADD_TRIVIAL. In the trivial cases and for any architecture-specific optimized implementations, the overhead of the errno setting might be significant, but I think that's best handled through compiler built-in functions rather than providing separate no-errno versions in glibc (and likewise there are no __*_finite entry points for these function provided, __*_finite effectively being no-errno versions at present in most cases). Tested for x86_64 and x86, with both GCC 6 and GCC 7. Tested for mips64 (all three ABIs, both hard and soft float) and powerpc with GCC 7.

* Fix -Os gnu_dev_* linknamespace, localplt issues (bug 15105, bug 19463).Joseph Myers2018-02-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building with -Os produces linknamespace and localplt failures for, among other functions, gnu_dev_major, gnu_dev_minor and gnu_dev_makedev. The issue is that those functions are not inlined when building with -Os. While one could force them to be inlined in that case, it seems more natural to fix this issue similarly to other namespace issues. Thus, this patch makes gnu_dev_* into weak aliases for hidden symbols __gnu_dev_*; __gnu_dev_* are then defined as inlines in the internal include/sys/sysmacros.h, and uses of gnu_dev_* (often via the macros major, minor and makedev) for which there are namespace issues are changed to use __gnu_dev_*; where there are no namespace issues, use of libc_hidden_proto serves to avoid unnecessary local PLT entry use. Tested for x86_64, (a) without -Os, to verify the testsuite continues to pass without problems and that the functions called under their new names continue to be inlined as expected in that case; (b) with -Os, to verify that the linknamespace and localplt failures in question go away (but because of other such failures present, neither of the relevant bugs can yet be closed).

* hurd: Fix getifaddrs / freeifaddrs expositionSamuel Thibault2018-01-281-2/+0
| | | | | | | | | | | 400669754de4 ('hurd: Fix nscd build') had the side effect of making libc's freeaddrinfo expose freeifaddrs through __check_pf. We can just move the renames to gai.c itself, along others. * sysdeps/mach/hurd/check_pf.c (__getifaddrs, __freeifaddrs): Do not define macros. * nscd/gai.c (__getifaddrs): Define macro to getifaddrs. (__freeifaddrs): Define macro to freeifaddrs.
* hurd: take __USE_EXTERN_INLINES into account and restrict inlinesSamuel Thibault2018-01-281-0/+12
