| | | | | | | | | | | | | | | | | | | | | | Handle the SO_TIMESTAMP{NS} similar to recvmsg: for !__ASSUME_TIME64_SYSCALLS it converts the first 32-bit time SO_TIMESTAMP or SO_TIMESTAMPNS and appends it to the control buffer if has extra space or returns MSG_CTRUNC otherwise. The 32-bit time field is kept as-is. Also for !__ASSUME_TIME64_SYSCALLS it limits the maximum number of 'struct mmsghdr *' to IOV_MAX (and also increases the stack size requirement to IOV_MAX times sizeof (socklen_t)). The Linux imposes a similar limit to sendmmsg, so bound the array size on recvmmsg is not unreasonable. And this will be used only on older when building with 32-bit time support.

* Add build option to disable usage of scv on powerpcMatheus Castanho2021-06-1010-13/+59
| | | | | | | | | | | | | | | | | Commit 68ab82f56690ada86ac1e0c46bad06ba189a10ef added support for the scv syscall ABI on powerpc. Since then systems that have kernel and processor support started using scv. However adding the proper support for a new syscall ABI requires changes to several other projects (e.g. qemu, valgrind, strace, kernel), which are gradually receiving support. Meanwhile, having a way to disable scv on glibc at build time can be useful for distros that may encounter conflicts with projects that still do not support the scv ABI, buying time until proper support is added. This commit adds a --disable-scv option that disables scv support and uses sc for all syscalls, like before commit 68ab82f56690ada86ac1e0c46bad06ba189a10ef.

* nptl: Avoid async cancellation to wrongly update __nptl_nthreads (BZ #19366)Adhemerval Zanella2021-06-091-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The testcase provided on BZ#19366 may update __nptl_nthreads in a wrong order, triggering an early process exit because the thread decrement the value twice. The issue is once the thread exits without acting on cancellation, it decreaments '__nptl_nthreads' and then atomically set 'cancelhandling' with EXITING_BIT (thus preventing further cancellation handler to act). The issue happens if a SIGCANCEL is received between checking '__ntpl_nthreads' and setting EXITING_BIT. To avoid it, the '__nptl_nthreads' decrement is moved after EXITING_BIT. It does fully follow the POSIX XSH 2.9.5 Thread Cancellation under the heading Thread Cancellation Cleanup Handlers that states that when a cancellation request is acted upon, or when a thread calls pthread_exit(), the thread first disables cancellation by setting its cancelability state to PTHREAD_CANCEL_DISABLE and its cancelability type to PTHREAD_CANCEL_DEFERRED. The issue is '__pthread_enable_asynccancel' explicit enabled assynchrnous cancellation, so an interrupted syscall within the cancellation cleanup handlers might see an invalid cancelling type (a possible fix might be possible with my proposed solution to BZ#12683). Trying to come up with a test is quite hard since it requires to mimic the timing issue described below, however I see that the bug report reproducer does not early exit anymore. Checked on x86_64-linux-gnu.
* nptl: Use pthread_kill on pthread_cancelAdhemerval Zanella2021-06-093-11/+15
| | | | | | | | | | It consolidates the tgkill call and it is the first step of making pthread_cancel async-signal-safe. It also fix a possible issue where the 'struct pthread' tid is not read atomically, which might send an invalid cancellation signal (similar to what db988e50a87f613cb6b9e98a2fc66a4848bc3546 fixed for pthread_join).

* nptl: Implement raise in terms of pthread_killAdhemerval Zanella2021-06-098-71/+50
| | | | | | | | | | | | | | | | Now that pthread_kill is provided by libc.so it is possible to implement the generic POSIX implementation as 'pthread_kill(pthread_self(), sig)'. For Linux implementation, pthread_kill read the targeting TID from the TCB. For raise, this it not possible because it would make raise fail when issue after vfork (where creates the resulting process has a different TID from the parent, but its TCB is not updated as for pthread_create). To make raise use pthread_kill, it is make usable from vfork by getting the target thread id through gettid syscall. Checked on x86_64-linux-gnu and aarch64-linux-gnu.
* nptl: Move cancel type out of cancelhandlingAdhemerval Zanella2021-06-098-170/+35
| | | | | | | | | | | | | | Now that the thread cancellation type is not accessed concurrently anymore, it is possible to move it out the cancelhandling. By removing the cancel state out of the internal thread cancel handling state there is no need to check if cancelled bit was set in CAS operation. It allows simplifing the cancellation wrappers and the CANCEL_CANCELED_AND_ASYNCHRONOUS is removed. Checked on x86_64-linux-gnu and aarch64-linux-gnu.
* nptl: Move cancel state out of cancelhandlingAdhemerval Zanella2021-06-0914-63/+34
| | | | | | | | | | | | | | | Now that thread cancellation state is not accessed concurrently anymore, it is possible to move it out the 'cancelhandling'. The code is also simplified: CANCELLATION_P is replaced with a internal pthread_testcancel call and the CANCELSTATE_BIT{MASK} is removed. With this behavior pthread_setcancelstate does not require to act on cancellation if cancel type is asynchronous (is already handled either by pthread_setcanceltype or by the signal handler). Checked on x86_64-linux-gnu and aarch64-linux-gnu.
* nptl: Remove CANCELING_BITMASKAdhemerval Zanella2021-06-094-106/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | The CANCELING_BITMASK is used as an optimization to avoid sending the signal when pthread_cancel is called in a concurrent manner. This requires then to put both the cancellation state and type on a shared state (cancelhandling), since 'pthread_cancel' checks whether cancellation is enabled and asynchrnous to either cancel itself of sending the signal. It also requires handle the CANCELING_BITMASK on __pthread_disable_asynccancel, however this incurs in the same issues described on BZ#12683: the cancellation is acted upon even *after* syscall returns with user visible side-effects. This patch removes this optimization and simplifies the pthread cancellation implementation: pthread_cancel now first checks if cancellation is already pending and if not always, sends a signal if the target is not itself. The SIGCANCEL handler is also simpified since there is not need to setup a CAS loop. It also allows to move both the cancellation state and mode out of 'cancelhadling' (it is done in subsequent patches). Checked on x86_64-linux-gnu and aarch64-linux-gnu.
* nptl: Install cancellation handler on pthread_cancelAdhemerval Zanella2021-06-094-45/+28

* nptl: Deallocate the thread stack on setup failure (BZ #19511)Adhemerval Zanella2021-06-093-88/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To setup either the thread scheduling parameters or affinity, pthread_create enforce synchronization on created thread to wait until its parent either release PD ownership or send a cancellation signal if a failure occurs. However, cancelling the thread does not deallocate the newly created stack since cancellation expects that a pthread_join to deallocate any allocated thread resouces (threads stack or TLS). This patch changes on how the thread resource is deallocate in case of failure to be synchronous, where the creating thread will signal the created thread to exit early so it could be joined. The creating thread will be reponsible for the resource cleanup before returning to the caller. To signal the creating thread that a failure has occured, an unused 'struct pthread' member, parent_cancelhandling_unsed, now indicates whether the setup has failed so creating thread can proper exit. This strategy also simplifies by not using thread cancellation and thus not running libgcc_so load in the signal handler (which is avoided in thread cancellation since 'pthread_cancel' is the one responsible to dlopen libgcc_s). Another advantage is since the early exit is move to first step at thread creation, the signal mask is not already set and thus it can not act on change ID setxid handler. Checked on x86_64-linux-gnu and aarch64-linux-gnu.
