2018-07-24x86/CET: Extend arch_prctl syscall for CET controlH.J. Lu
CET arch_prctl bits should be defined in <asm/prctl.h> from Linux kernel header files. Add x86 <include/asm/prctl.h> for pre-CET kernel header files. Note: sysdeps/unix/sysv/linux/x86/include/asm/prctl.h should be removed if <asm/prctl.h> from the required kernel header files contains CET arch_prctl bits. /* CET features: IBT: GNU_PROPERTY_X86_FEATURE_1_IBT SHSTK: GNU_PROPERTY_X86_FEATURE_1_SHSTK */ /* Return CET features in unsigned long long *addr: features: addr[0]. shadow stack base address: addr[1]. shadow stack size: addr[2]. */ # define ARCH_CET_STATUS 0x3001 /* Disable CET features in unsigned int features. */ # define ARCH_CET_DISABLE 0x3002 /* Lock all CET features. */ # define ARCH_CET_LOCK 0x3003 /* Allocate a new shadow stack with unsigned long long *addr: IN: requested shadow stack size: *addr.

2018-07-24nptl: Add C11 threads cnd_* functionsAdhemerval Zanella

2018-07-24nptl: Add C11 threads thrd_* functionsAdhemerval Zanella
This patch adds the thrd_* definitions from C11 threads (ISO/IEC 9899:2011), more specifically thrd_create, thrd_curent, rhd_detach, thrd_equal, thrd_exit, thrd_join, thrd_sleep, thrd_yield, and required types. Mostly of the definitions are composed based on POSIX conterparts, such as thrd_t (using pthread_t). For thrd_* function internally direct POSIX pthread call are used with the exceptions: 1. thrd_start uses pthread_create internal implementation, but changes how to actually calls the start routine. This is due the difference in signature between POSIX and C11, where former return a 'void *' and latter 'int'. To avoid calling convention issues due 'void *' to int cast, routines from C11 threads are started slight different than default pthread one. Explicit cast to expected return are used internally on pthread_create and the result is stored back to void also with an explicit cast. 2. thrd_sleep uses nanosleep internal direct syscall to avoid clobbering errno and to handle expected standard return codes. It is a cancellation entrypoint to be consistent with both thrd_join and cnd_{timed}wait. 3. thrd_yield also uses internal direct syscall to avoid errno clobbering. Checked with a build for all major ABI (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabi, i386-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu [1], mips{64}-linux-gnu, nios2-linux-gnu, powerpc{64le}-linux-gnu, s390{x}-linux-gnu, sparc{64}-linux-gnu, and x86_64-linux-gnu).

2018-07-24Add <bits/indirect-return.h>H.J. Lu
Add <bits/indirect-return.h> and include it in <ucontext.h>. __INDIRECT_RETURN defined in <bits/indirect-return.h> indicates if swapcontext requires special compiler treatment. The default __INDIRECT_RETURN is empty. On x86, when shadow stack is enabled, __INDIRECT_RETURN is defined with indirect_return attribute, which has been added to GCC 9, to indicate that swapcontext returns via indirect branch. Otherwise __INDIRECT_RETURN is defined with returns_twice attribute.

2018-07-24x86: Update vfork to pop shadow stackH.J. Lu
The shadow stack prevents us from pushing the saved return PC onto the stack and returning normally. Instead we pop the shadow stack and return directly.

2018-07-18Avoid insecure usage of tmpnam in tests.Joseph Myers
Various glibc testcases use tmpnam in ways subject to race conditions (generate a temporary file name, then later open that file without O_EXCL). This patch fixes those tests to use mkstemp - generally a minimal local fix to use mkstemp instead of tmpnam, rather than a larger fix to use other testsuite infrastructure for temporary files. The unchanged use of tmpnam in posix/wordexp-test.c would fail safe in the event of a race (it's generating a name for use with mkdir rather than for a file to be opened for writing). Tested for x86_64. * grp/tst_fgetgrent.c: Include <unistd.h>. (main): Use mkstemp instead of tmpnam. * io/test-utime.c (main): Likewise. * posix/annexc.c (macrofile): Change to modifiable array.
