2018-03-05nptl: Fix tst-cancel4 sendto testsAdhemerval Zanella
Now that send might be implemented calling sendto syscall on Linux, I am seeing some issue in some kernel configurations where tst-cancel4 sendto do not block as expected. The socket used to force the syscall blocking is used with default system configuration for buffer sending size, which might not be suffice to force blocking. This patch fixes it by explicit setting buffer socket lower than the buffer size used. It also enables sendto cancellation tests to work in both ways (since internally send is implemented routing to sendto on Linux kernel). The patch also removes unrequired make rules on some archictures for send/recv. The generic nptl Makefile already set the compiler flags required on some architectures for correct unwinding and libc object are not strictly required to support unwind (since pthread_cancel requires linking against libpthread). Checked on aarch64-linux-gnu and x86_64-linux-gnu. I also did a sniff test with tst-cancel{4,5} on a simulated mips64-linux-gnu. * nptl/tst-cancel4-common.h (set_socket_buffer): New function. * nptl/tst-cancel4-common.c (do_test): Call set_socket_buffer for socketpair endpoint. * nptl/tst-cancel4.c (tf_send): Call set_socket_buffer and use WRITE_BUFFER_SIZE as buffer size for sending socket. (tf_sendto): Use SOCK_STREAM instead of SOCK_DGRAM and fix an issue on system where send is implemented with sendto syscall. * sysdeps/unix/sysv/linux/mips/mips64/Makefile [$(subdir) = socket] (CFLAGS-recv.c, CFLAGS-send.c): Remove rules. [$(subdir) = nptl] (CFLAGS-recv.c, CFLAGS-send.c): Likewise. * sysdeps/unix/sysv/linux/riscv/rv64/Makefile: Remove file.

2017-05-31posix: Implement preadv2 and pwritev2Adhemerval Zanella
This patch adds support of preadv2 and pwritev2 which are similar to preadv/pwritev but with an extra flag argument. As for preadv/pwritev both interfaces are added a non-standard GNU API. For default 'posix' implementation trying to emulate the Linux supported flags is troublesome: * We can not temporary change the file state of the O_DSYNC and O_SYNC flags to emulate RWF_{D}SYNC (attempts to change the state of using fcntl are silently ignored). * IOCB_HIPRI requires the file opened in O_DIRECT and uses an internal semantic not provided by any other flag (O_NONBLOCK for instance). So default sysdeps/posix implementations fails with EOPNOTSUPP for any non supported flag (which are none currently) calls generic preadv/pwritev. Basically this implementation supports only preadv2 called as preadv (with flags sets to 0). The Linux one uses the preadv2/pwritev2 syscall if defined, otherwise it call preadv/writev. Instead of using the previous __ASSUME_* to unconditionally issue the syscall (and avoid building the fallback routine), it call pread/write if the preadv2/pwritev2 syscalls fails. The idea is just avoid adding another __ASSUME_* and checking each architecture on every kernel bump and simplify code conditionals. Checked on x86_64-linux-gnu and on i686-linux-gnu and a check with run-built-tests=no on aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabihf, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu, mips{64,64n32}-linux-gnu, nios2-linux-gnu, powerpc{64,64le}-linux-gnu, s390{x}-linux-gnu, sparc{64,v9}-linux-gnu, tile{gx,pro}-linux-gnu, and sh4-linux-gnu (all using gcc 6.3). * NEWS: Add note about pwritev2 and preadv2 inclusion. * misc/Makefile (routines): Add preadv2, preadv64v2, pwritev2, and pwritev64v2.

2017-04-25Fix sys/socket.h namespace issues from sys/uio.h inclusion (bug 21426).Joseph Myers
sys/socket.h includes sys/uio.h to get the definition of the iovec structure. POSIX allows sys/socket.h to make all sys/uio.h symbols visible. However, all of sys/uio.h is XSI-shaded, so for non-XSI POSIX this results in conformtest failures (for sys/socket.h and other headers that include it): Namespace violation: "UIO_MAXIOV" Namespace violation: "readv" Namespace violation: "writev" Now, there is some ambiguity in POSIX about what namespace reservations apply in this case - see http://austingroupbugs.net/view.php?id=1127 - but glibc convention would still avoid declaring readv and writev, for example, for feature test macros that don't include them (if only headers from the relevant standard are included), even if such declarations are permitted, so there is a bug here according to glibc conventions. This patch moves the struct iovec definition to a new bits/types/struct_iovec.h header and includes that from sys/socket.h instead of including the whole of sys/uio.h. This fixes the namespace issue; however, three files in glibc that were relying on the implicit inclusion needed to be updated to include sys/uio.h explicitly. So there is a question of whether sys/socket.h should continue to include sys/uio.h under some conditions, such as __USE_XOPEN or __USE_MISC or __USE_XOPEN || __USE_MISC, for greater compatibility with code that (wrongly) expects this optional inclusion to be present there. (I think the three affected files in glibc should still have explicit sys/uio.h inclusions added in any case, however.) Tested for x86_64.

2016-07-05nptl: Add more coverage in tst-cancel4Adhemerval Zanella
This patch adds early cancel test for open syscall through a FIFO (thus makign subsequent call to open block until the other end is also opened). It also cleanup the sigpause tests by using sigpause along with SIGINT instead of __xpg_sigpause and SIGCANCEL. Since the idea is just to test the cancellation handling there is no need to expose internal glibc implementation details to the test through pthreadP.h inclusion.

2016-06-13nptl: Add sendmmsg and recvmmsg cancellation testsAdhemerval Zanella
This patch adds cancellation tests for both sendmmsg and recvmmsg syscalls. Since for some system configuration (x86_64/i686 on older kernels and non-Linux platforms), the tests are added as two independent that report as unsupported if the syscall is not presented. Both new tests uses the already tst-cancel4.c code, which as moved to a common tst-cancel4-common{.c,h} files. Tested on x86_64 and i686. * nptl/Makefile (test): Add tst-cancel4_1 and tst-cancel4_2. * nptl/tst-cancel4-common.c: New file. * nptl/tst-cancel4-common.h: Likewise. * nptl/tst-cancel4.c: Move common definitions to tst-cancel4-common.{c,h} file. * nptl/tst-cancel4_1.c: New test. * nptl/tst-cancel4_2.c: New test.
