| | | | | | | | | | | | | | | | | | | | | | This was already present for the other architectures. I think we skipped this because glibc seems to have an incorrect definition (int rather than long), but the kernel has the sane definition (just not in a uapi header).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX also says that ucontext_t's uc_sigmask has type sigset_t. MIPS64 strace needs this. The #define is to keep chromium off our lawn; otherwise it tries to redefine all this stuff itself. We should probably clean that up and remove the #define.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | No one's reported this, but I saw it in an Android port of fuser(1). We still have lots of problems in our network headers because we get most of the structs direct from the kernel, and it doesn't use types like this (which is why we've got away without this one for so long). One day we should probably look at cleaning that up, but doing so can wait.

* | [x86,x86_64] Fix libgcc unwinding through signalPavel Chupin2014-10-274-43/+211
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change provides __restore/__restore_rt on x86 and __restore_rt on x86_64 with unwinding information to be able to unwind through signal frame via libgcc provided unwinding interface. See comments inlined for more details. Also remove the test that had a dependency on __attribute__((cleanup(foo_cleanup))). It doesn't provide us with any better test coverage than we have from the newer tests, and it doesn't work well across a variety architectures (presumably because no one uses this attribute in the real world). Tested this on host via bionic-unit-tests-run-on-host on both x86 and x86-64.

* | Use the kernel's sa_restorer for aarch64.Elliott Hughes2014-10-273-48/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gdb was happy with what we had, but libgcc and libunwind weren't. libgcc is happy with the kernel's restorer (because of the extra nop), though libunwind looks like it's going to need code changes regardless. We could make our restorer more like the kernel's one, but why bother when we can just let the kernel supply the canonical one?

* | Fix signal trampolines.Elliott Hughes2014-10-2712-12/+183
|/ | | | | | | | | | | | | | | | | | | | | | | | * LP32 should use sa_restorer too. gdb expects this, and future (>= 3.15) x86 kernels will apparently stop supporting the case where SA_RESTORER isn't set. * gdb and libunwind care about the exact instruction sequences, so we need to modify the code slightly in a few cases to match what they're looking for. * gdb also cares about the exact function names (for some architectures), so we need to use __restore and __restore_rt rather than __sigreturn and __rt_sigreturn. * It's possible that we don't have a VDSO; dl_iterate_phdr shouldn't assume that getauxval(AT_SYSINFO_EHDR) will return a non-null pointer. This fixes unwinding through a signal handler in gdb for all architectures. It doesn't fix libunwind for arm and arm64. I'll keep investigating that...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From the release notes: Changes affecting future time stamps Pacific/Fiji will observe DST from 2014-11-02 02:00 to 2015-01-18 03:00. (Thanks to Ken Rylander for the heads-up.) Guess that future years will use a similar pattern. A new Zone Pacific/Bougainville, for the part of Papua New Guinea that plans to switch from UTC+10 to UTC+11 on 2014-12-28 at 02:00. (Thanks to Kiley Walbom for the heads-up.) Changes affecting time zone abbreviations Since Belarus is not changing its clocks even though Moscow is, the time zone abbreviation in Europe/Minsk is changing from FET to its more-traditional value MSK on 2014-10-26 at 01:00. (Thanks to Alexander Bokovoy for the heads-up about Belarus.) The new abbreviation IDT stands for the pre-1976 use of UT+8 in Indochina, to distinguish it better from ICT (UT+7). Changes affecting past time stamps Many time stamps have been corrected for Asia/Ho_Chi_Minh before 1976 (thanks to Trần Ngọc Quân for an indirect pointer to Trần Tiến Bình's authoritative book). Asia/Ho_Chi_Minh has been added to zone1970.tab, to give tzselect users in Vietnam two choices, since north and south Vietnam disagreed after our 1970 cutoff. Asia/Phnom_Penh and Asia/Vientiane have been turned into links, as they differed from existing zones only for older time stamps. As usual, these changes affect pre-1970 time stamps only. Their old contents have been moved to the 'backzone' file. Bug: 18085936 (cherry picked from commit a05c2a2a705c8298154db6665cbbb4dbe3cdbbd5) Change-Id: If0253cc1515e1bc98e99c6e24eec797836ca7c27

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When setting a repeat timer using the SIGEV_THREAD mechanism, it's possible that the callback can be called after the timer is disarmed or deleted. This happens because the kernel can generate signals that the timer thread will continue to handle even after the timer is supposed to be off. Add two new tests to verify that disarming/deleting doesn't continue to call the callback. Modify the repeat test to finish more quickly than before. Refactor the Counter implementation a bit.

| | | | | | | | | | | | | | | | | | | | For silvermont, the __popcountsi2 symbol does not get exported by libc. But for atom, this symbol is exported. Since we already exported this symbol for previous releases, it's better to just follow through and force the export, but only for 32 bit. x86 64 bit will not export this symbol.
