* posix: Add p{read,write}v2 RWF_NOWAIT flag (BZ#21738)Adhemerval Zanella2017-07-114-10/+18
| | | | | | | | | | | | | | Linux 4.12 (b745fafaf70c0a98a2e1e7ac8cb14542889ceb0e) adds a new p{read,write}v2 flag RWF_NOWAIT. This patch adds it for linux uio-ext.h header. Checked on x86_64-linux-gnu (on a 4.10 kernel). [BZ #21738] * manual/llio.texi (RWF_NOWAIT): New item. * misc/tst-preadvwritev2-common.c (do_test_with_invalid_flags): Add RWF_NOWAIT check. * sysdeps/unix/sysv/linux/bits/uio-ext.h (RWF_NOWAIT): New flag.

* S390: Fix tst-ptrace-singleblock if kernel does not support PTRACE_SINGLEBLOCK.Stefan Liebler2017-07-112-2/+57
| | | | | | | | | | | | | | | | | | The request PTRACE_SINGLEBLOCK was introduced in Linux 3.15. Thus the ptrace call will fail on older kernels. Thus the test is now testing PTRACE_SINGLEBLOCK with data argument pointing to a buffer on stack which is assumed to fail. If the request would be interpreted as PTRACE_GETREGS, then the ptrace call will not fail and the regs are written to buf. If we run with a kernel with support for PTRACE_SINGLEBLOCK a ptrace call with data=NULL, returns zero with no error. If we run with a kernel without support for PTRACE_SINGLEBLOCK a ptrace call with data=NULL reports an error. In the latter case, the test is just continuing with PTRACE_CONT. ChangeLog: * sysdeps/unix/sysv/linux/s390/tst-ptrace-singleblock.c: Support running on kernels without PTRACE_SINGLEBLOCK.

| | | | | | | | | | | | | | | This patch increases the timeouts for some tests that I've seen timing out on slow systems in my 2.26 release testing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the recent import of month names from CLDRv31 (bug 21217, commit c853f14) more imports are also needed, mostly abbreviated month names. This patch also updates May (full month name) in ps_AF which was skipped in the previous patch. Incidentally, this import fixes bug 17225 (ar_SY) and partially bug 19066 (ar_SA).

* x86-64: Align the stack in __tls_get_addr [BZ #21609]H.J. Lu2017-07-067-2/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | This change forces realignment of the stack pointer in __tls_get_addr, so that binaries compiled by GCCs older than GCC 4.9: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066 continue to work even if vector instructions are used in glibc which require the ABI stack realignment. __tls_get_addr_slow is added to handle the slow paths in the default implementation of__tls_get_addr in elf/dl-tls.c. The new __tls_get_addr calls __tls_get_addr_slow after realigning the stack. Internal calls within ld.so go directly to the default implementation of __tls_get_addr because they do not need stack realignment. [BZ #21609] * sysdeps/x86_64/Makefile (sysdep-dl-routines): Add tls_get_addr.

* Single threaded stdio optimizationSzabolcs Nagy2017-07-0415-0/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Locking overhead can be significant in some stdio operations that are common in single threaded applications. This patch adds the _IO_FLAGS2_NEED_LOCK flag to indicate if an _IO_FILE object needs to be locked and some of the stdio functions just jump to their _unlocked variant when not. The flag is set on all _IO_FILE objects when the first thread is created. A new GLIBC_PRIVATE libc symbol, _IO_enable_locks, was added to do this from libpthread. The optimization can be applied to more stdio functions, currently it is only applied to single flag check or single non-wide-char standard operations. The flag should probably be never set for files with _IO_USER_LOCK, but that's just a further optimization, not a correctness requirement. The optimization is valid in a single thread because stdio operations are non-as-safe (so lock state is not observable from a signal handler) and stdio locks are recursive (so lock state is not observable via deadlock). The optimization is not valid if a thread may be created while an stdio lock is taken and thus it should be disabled if any user code may run during an stdio operation (interposed malloc, printf hooks, etc). This makes the optimization more complicated for some stdio operations (e.g. printf), but those are bigger and thus less important to optimize so this patch does not try to do that. * libio/libio.h (_IO_FLAGS2_NEED_LOCK, _IO_need_lock): Define. * libio/libioP.h (_IO_enable_locks): Declare. * libio/Versions (_IO_enable_locks): New symbol. * libio/genops.c (_IO_enable_locks): Define.

* resolv: Automatically reload a changed /etc/resolv.conf file [BZ #984]Florian Weimer2017-07-0311-94/+272
| | | | | | | | | | This commit enhances the stub resolver to reload the configuration in the per-thread _res object if the /etc/resolv.conf file has changed. The resolver checks whether the application has modified _res and will not overwrite the _res object in that case. The struct resolv_context mechanism is used to check the configuration file only once per name lookup.
* resolv: Mirror the entire resolver configuration in struct resolv_confFlorian Weimer2017-07-037-116/+572
| | | | | | | | | | | | | | This commit adds the remaining unchanging members (which are loaded from /etc/resolv.conf) to struct resolv_conf. The extended name server list is currently not used by the stub resolver. The switch depends on a cleanup: The _u._ext.nssocks array stores just a single socket, and needs to be replaced with a single socket value. (The compatibility gethostname implementation does not use the extended addres sort list, either. Updating the compat code is not worthwhile.)
* resolv: Lift domain search list limits [BZ #19569] [BZ #21475]Florian Weimer2017-07-038-81/+382
| | | | | | | This change uses the extended resolver state in struct resolv_conf to store the search list. If applications have not patched the _res object directly, this extended search list will be used by the stub resolver during name resolution.
* resolv: Introduce struct resolv_conf with extended resolver stateFlorian Weimer2017-07-039-10/+470
| | | | | | | | | | | | This change provides additional resolver configuration state which is not exposed through the _res ABI. It reuses the existing initstamp field in the supposedly-private part of _res. Some effort is undertaken to avoid memory safety issues introduced by applications which directly patch the _res object. With this commit, only the initstamp field is moved into struct resolv_conf. Additional members will be added later, eventually migrating the entire resolver configuration.
