2017-11-15The -Wstringop-truncation option new in GCC 8 detects common misusesMartin Sebor
of the strncat and strncpy function that may result in truncating the copied string before the terminating NUL. To avoid false positive warnings for correct code that intentionally creates sequences of characters that aren't guaranteed to be NUL-terminated, arrays that are intended to store such sequences should be decorated with a new nonstring attribute. This change add this attribute to Glibc and uses it to suppress such false positives. ChangeLog: * misc/sys/cdefs.h (__attribute_nonstring__): New macro. * sysdeps/gnu/bits/utmp.h (struct utmp): Use it. * sysdeps/unix/sysv/linux/s390/bits/utmp.h (struct utmp): Same.
2017-11-15linux ttyname{_r}: Add testsLuke Shumaker
Add a new tst-ttyname test that includes several named sub-testcases. This patch is ordered after the patches with the fixes that it tests for (to avoid breaking `git bisect`), but for reference, here's how each relevant change so far affected the testcases in this commit, starting with 15e9a4f378c8607c2ae1aa465436af4321db0e23: | | before | | make checks | don't | | | 15e9a4f | 15e9a4f | consistent | bail | |---------------------------------+---------+---------+-------------+-------| | basic smoketest | PASS | PASS | PASS | PASS | | no conflict, no match | PASS[1] | PASS | PASS | PASS | | no conflict, console | PASS | FAIL! | FAIL | PASS! | | conflict, no match | FAIL | PASS! | PASS | PASS | | conflict, console | FAIL | FAIL | FAIL | PASS! | | with readlink target | PASS | PASS | PASS | PASS | | with readlink trap; fallback | FAIL | FAIL | FAIL | PASS! | | with readlink trap; no fallback | FAIL | PASS! | PASS | PASS | | with search-path trap | FAIL | FAIL | PASS! | PASS | |---------------------------------+---------+---------+-------------+-------| | | 4/9 | 5/9 | 6/9 | 9/9 | [1]: 15e9a4f introduced a semantic that, under certain failure conditions, ttyname sets errno=ENODEV, where previously it didn't set errno; it's not quite fair to hold "before 15e9a4f" ttyname to those new semantics. This testcase actually fails, but would have passed if we tested for the old the semantics. Each of the failing tests before 15e9a4f are all essentially the same bug: that it returns a PTY slave with the correct minor device number, but from the wrong devpts filesystem instance. 15e9a4f sought to fix this, but missed several of the cases that can cause this to happen, and also broke the case where both the erroneous PTY and the correct PTY exist.

2017-11-15linux ttyname{_r}: Don't bail prematurely [BZ #22145]Luke Shumaker
Commit 15e9a4f378c8607c2ae1aa465436af4321db0e23 introduced logic for ttyname() sending back ENODEV to signal that we can't get a name for the TTY because we inherited it from a different mount namespace. However, just because we inherited it from a different mount namespace and it isn't available at its original path, doesn't mean that its name is unknowable; we can still try to find it by allowing the normal fall back on iterating through devices. An example scenario where this happens is with "/dev/console" in containers. It's a common practice among container managers to allocate a PTY master/slave pair in the host's mount namespace (the slave having a path like "/dev/pty/$X"), bind mount the slave to "/dev/console" in the container's mount namespace, and send the slave FD to a process in the container. Inside of the container, the slave-end isn't available at its original path ("/dev/pts/$X"), since the container mount namespace has a separate devpts instance from the host (that path may or may not exist in the container; if it does exist, it's not the same PTY slave device). Currently ttyname{_r} sees that the file at the original "/dev/pts/$X" path doesn't match the FD passed to it, and fails early and gives up, even though if it kept searching it would find the TTY at "/dev/console". Fix that; don't have the ENODEV path force an early return inhibiting the fall-back search. This change is based on the previous patch that adds use of is_mytty in getttyname and getttyname_r. Without that change, this effectively reverts 15e9a4f, which made us disregard the false similarity of file pointed to by "/proc/self/fd/$Y", because if it doesn't bail prematurely then that file ("/dev/pts/$X") will just come up again anyway in the fall-back search.

2017-11-15linux ttyname{_r}: Make tty checks consistentLuke Shumaker
In the ttyname and ttyname_r routines on Linux, at several points it needs to check if a given TTY is the TTY we are looking for. It used to be that this check was (to see if `maybe` is `mytty`): __xstat64(_STAT_VER, maybe_filename, &maybe) == 0 #ifdef _STATBUF_ST_RDEV && S_ISCHR(maybe.st_mode) && maybe.st_rdev == mytty.st_rdev #else && maybe.st_ino == mytty.st_ino && maybe.st_dev == mytty.st_dev #endif This check appears in several places. Then, one of the changes made in commit 15e9a4f378c8607c2ae1aa465436af4321db0e23 was to change that check to: __xstat64(_STAT_VER, maybe_filename, &maybe) == 0 #ifdef _STATBUF_ST_RDEV && S_ISCHR(maybe.st_mode) && maybe.st_rdev == mytty.st_rdev #endif && maybe.st_ino == mytty.st_ino && maybe.st_dev == mytty.st_dev That is, it made the st_ino and st_dev parts of the check happen even if we have the st_rdev member. This is an important change, because the kernel allows multiple devpts filesystem instances to be created; a device file in one devpts instance may share the same st_rdev with a file in another devpts instance, but they aren't the same file. This check appears twice in each file (ttyname.c and ttyname_r.c), once (in ttyname and __ttyname_r) to check if a candidate file found by inspecting /proc is the desired TTY, and once (in getttyname and getttyname_r) to check if a candidate file found by searching /dev is the desired TTY. However, 15e9a4f only updated the checks for files found via /proc; but the concern about collisions between devpts instances is just as valid for files found via /dev. So, update all 4 occurrences the check to be consistent with the version of the check introduced in 15e9a4f. Make it easy to keep all 4 occurrences of the check consistent by pulling it in to a static inline function, is_mytty. Reviewed-by: Christian Brauner <christian.brauner@ubuntu.com>

2017-11-15linux: Include <sysdep-cancel.h> for epoll_waitLuke Shumaker
The epoll_wait wrapper uses the raw syscall if __NR_epoll_wait is defined, and falls back to calling epoll_pwait(..., NULL) if it isn't defined. However, it didn't include the appropriate headers for __NR_epoll_wait to be defined, so it was *always* falling back to calling epoll_pwait! This mistake was introduced in b62c3815912bc679a966134affdedd3f35ae8621, when epoll_wait changed from being in syscalls.list to always having a C wrapper.

2017-11-15Use __builtin_tgmath in tgmath.h with GCC 8 (bug 21660).Joseph Myers
GCC mainline now supports __builtin_tgmath to allow <tgmath.h> macro implementations that expand their arguments only once, so avoiding exponential blowup in the size of macro expansions when calls to those macros are nested in arguments to those macros. This patch makes glibc's tgmath.h support using __builtin_tgmath, as a much simpler and more efficient alternative to the existing implementation. (As a side effect, the new feature would make it much more practical to support decimal floating point in <tgmath.h> with new compilers; currently, libdfp does not provide a <tgmath.h> implementation, and making decimal arguments cause integer arguments to be considered of type _Decimal64 instead of double would have been very problematic in the old implementation.)

2017-11-14Fix string/tester.c build with GCC 8.Joseph Myers
GCC 8 warns about more cases of string functions truncating their output or not copying a trailing NUL byte. This patch fixes testsuite build failures caused by such warnings in string/tester.c. In general, the warnings are disabled around the relevant calls using DIAG_* macros, since the relevant cases are being deliberately tested. In one case, the warning is with -Wstringop-overflow= instead of -Wstringop-truncation; in that case, the conditional is __GNUC_PREREQ (7, 0) (being the version where -Wstringop-overflow= was introduced), to allow the conditional to be removed sooner, since it's harmless to disable the warning for a GCC version where it doesn't actually occur. In the case of warnings for strncpy calls in test_memcmp, the calls in question are changed to use memcpy, as they don't copy a trailing NUL and the point of that code is to test memcmp rather than strncpy. Tested (compilation) with GCC 8 for x86_64-linux-gnu with build-many-glibcs.py (in conjunction with Martin's patch to allow glibc to build). * string/tester.c (test_stpncpy): Disable -Wstringop-truncation for stpncpy calls for GCC 8.

2017-11-13ld.so: Add architecture specific fieldsH.J. Lu
To support Intel Control-flow Enforcement Technology (CET) run-time control: 1. An architecture specific field in the writable ld.so namespace is needed to indicate if CET features are enabled at run-time. 2. An architecture specific field in struct link_map is needed if CET features are enabled in an ELF module. This patch adds dl-procruntime.c to the writable ld.so namespace and link_map.h to struct link_map. Tested with build-many-glibcs.py. * elf/dl-support.c: Include <dl-procruntime.c>. * include/link.h: Include <link_map.h>. * sysdeps/generic/dl-procruntime.c: New file. * sysdeps/generic/link_map.h: Likewise. * sysdeps/generic/ldsodefs.h: Include <dl-procruntime.c> in the writable ld.so namespace.

Continuing the preparation for additional _FloatN / _FloatNx type support, this patch adds support in include/float.h.

For testing _Float32 / _Float64 / _Float32x / _Float64x functions with older compilers, such macros need to be defined for those types as well; for the older compilers, those types will always be typedefs for another type, so the definitions can be in terms of the macros for that other type.

This patch adds two new internal defines to set the internal pthread_mutex_t layout required by the supported ABIS: 1. __PTHREAD_MUTEX_NUSERS_AFTER_KIND which control whether to define __nusers fields before or after __kind. The preferred value for is 0 for new ports and it sets __nusers before __kind. 2. __PTHREAD_MUTEX_USE_UNION which control whether internal __spins and __list members will be place inside an union for linuxthreads compatibility. The preferred value is 0 for ports and it sets to not use an union to define both fields. It fixes the wrong offsets value for __kind value on x86_64-linux-gnu-x32.

2017-11-07nptl: Change tst-typesizes to _Static_assertAdhemerval Zanella
Instead of rely on runtime check to assure correct pthread types size a better strategy would use _Static_assert to trigger an error on build time (and thus allowing to check to potentially ABI breakage on cross-compiling make check). This patch moves nptl/tst-typesizes.c to libpthread build time on each specific initialization routine and also remove some runtime redundant asserts for the same type sizes.

2017-11-07nptl: Add tests for internal pthread_mutex_t offsetsAdhemerval Zanella
This patch adds a new build test to check for internal fields offsets for user visible internal field. Although currently the only field which is statically initialized to a non zero value is pthread_mutex_t.__data.__kind value, the tests also check the offset of __kind, __spins, __elision (if supported), and __list internal member. A internal header (pthread-offset.h) is added to each major ABI with the reference value.

2017-11-06arm: Implement memchr ifunc selection in CAdhemerval Zanella
This patch refactor ARM memchr ifunc selector to a C implementation. No functional change is expected, including ifunc resolution rules. It also reorganize the ifunc options code: 1. The memchr_impl.S is renamed to memchr_neon.S and multiple compilation options (which route to armv6t2/memchr one) is removed. The code to build if __ARM_NEON__ is defined is also simplified. 2. A memchr_noneon is added (which as build along previous ifunc resolution) and includes the armv6t2 direct. 3. Same as 2. for loader object. Alongside the aforementioned changes, it also some cleanus: - Internal memchr definition (__GI_memcpy) is now a hidden symbol. - No need to create hidden definition for the ifunc variants.
