2020-06-08pthread: Move back linking rules to nptl and htlSamuel Thibault
d6d74ec16 ('htl: Enable more tests') moved the linking rules from nptl/Makefile and htl/Makefile to the shared sysdeps/pthread/Makefile. But e.g. on powerpc some tests are added in sysdeps/powerpc/Makefile, which is included *after* sysdeps/pthread/Makefile, and thus the tests don't get affected by the rules and fail to link. For now let's just copy over the set of rules in both nptl/Makefile and htl/Makefile. * sysdeps/pthread/Makefile: Move libpthread linking rules to... * htl/Makefile: ... here and... * nptl/Makefile: ... there.

2020-05-12nptl: wait for pending setxid request also in detached thread (bug 25942)Andreas Schwab
There is a race between __nptl_setxid and exiting detached thread, which causes a deadlock on stack_cache_lock. The deadlock happens in this state: T1: setgroups -> __nptl_setxid (holding stack_cache_lock, waiting on cmdp->cntr == 0) T2 (detached, exiting): start_thread -> __deallocate_stack (waiting on stack_cache_lock) more threads waiting on stack_cache_lock in pthread_create For non-detached threads, start_thread waits for its own setxid handler to finish before exiting. Do this for detached threads as well.

2020-04-27nptl: Start new threads with all signals blocked [BZ #25098]Florian Weimer
New threads inherit the signal mask from the current thread. This means that signal handlers can run on the newly created thread immediately after the kernel has created the userspace thread, even before glibc has initialized the TCB. Consequently, new threads can observe uninitialized ctype data, among other things. To address this, block all signals before starting the thread, and pass the original signal mask to the start routine wrapper. On the new thread, first perform all thread initialization, and then unblock signals. The cost of doing this is two rt_sigprocmask system calls on the old thread, and one rt_sigprocmask system call on the new thread. (If there was a way to clone a new thread with a signals disabled, this could be brought down to one system call each.) The thread descriptor increases in size, too, and sigset_t is fairly large. This increase could be brought down by reusing space the in the descriptor which is not needed before running user code, or by switching to an internal sigset_t definition which only covers the signals supported by the kernel definition. (Part of the thread descriptor size increase is already offset by reduced stack usage in the thread start wrapper routine after this commit.) Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2020-04-21signal: Only handle on NSIG signals on signal functions (BZ #25657)Adhemerval Zanella
The upper bits of the sigset_t s not fully initialized in the signal mask calls that return information from kernel (sigprocmask, sigpending, and pthread_sigmask), since the exported sigset_t size (1024 bits) is larger than Linux support one (64 or 128 bits). It might make sigisemptyset/sigorset/sigandset fail if the mask is filled prior the call. This patch changes the internal signal function to handle up to supported Linux signal number (_NSIG), the remaining bits are untouched. Checked on x86_64-linux-gnu and i686-linux-gnu.

2020-02-19Block all signals on timer_create thread (BZ#10815)Adhemerval Zanella
The behavior of the signal mask on threads created by timer_create for SIGEV_THREAD timers are implementation-defined and glibc explicit unblocks all signals before calling the user-defined function. This behavior, although not incorrect standard-wise, opens a race if a program using a blocked rt-signal plus sigwaitinfo (and without an installed signal handler for the rt-signal) receives a signal while executing the used-defined function for SIGEV_THREAD. A better alternative discussed in bug report is to rather block all signals (besides the internal ones not available to application usage). This patch fixes this issue by only unblocking SIGSETXID (used on set*uid function) and SIGCANCEL (used for thread cancellation). Checked on x86_64-linux-gnu and i686-linux-gnu.
2020-02-18Introduce <elf-initfini.h> and ELF_INITFINI for all architecturesFlorian Weimer
This supersedes the init_array sysdeps directory. It allows us to check for ELF_INITFINI in both C and assembler code, and skip DT_INIT and DT_FINI processing completely on newer architectures. A new header file is needed because <dl-machine.h> is incompatible with assembler code. <sysdep.h> is compatible with assembler code, but it cannot be included in all assembler files because on some architectures, it redefines register names, and some assembler files conflict with that. <elf-initfini.h> is replicated for legacy architectures which need DT_INIT/DT_FINI support. New architectures follow the generic default and disable it.
