2021-12-21Linux: Fix 32-bit vDSO for clock_gettime on powerpc32maminjie
When the clock_id is CLOCK_PROCESS_CPUTIME_ID or CLOCK_THREAD_CPUTIME_ID, on the 5.10 kernel powerpc 32-bit, the 32-bit vDSO is executed successfully ( because the __kernel_clock_gettime in arch/powerpc/kernel/vdso32/gettimeofday.S does not support these two IDs, the 32-bit time_t syscall will be used), but tp32.tv_sec is equal to 0, causing the 64-bit time_t syscall to continue to be used, resulting in two system calls. Fix commit 72e84d1db22203e01a43268de71ea8669eca2863. Signed-off-by: maminjie <maminjie2@huawei.com> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
2021-07-12Linux: Use 32-bit vDSO for clock_gettime, gettimeofday, time (BZ# 28071)Adhemerval Zanella
The previous approach defeats the vDSO optimization on older kernels because a failing clock_gettime64 system call is performed on every function call. It also results in a clobbered errno value, exposing an OpenJDK bug (JDK-8270244). This patch fixes by open-code INLINE_VSYSCALL macro and replace all INLINE_SYSCALL_CALL with INTERNAL_SYSCALL_CALLS. Now for __clock_gettime64x, the 64-bit vDSO is used and the 32-bit vDSO is tried before falling back to 64-bit syscalls. The previous code preferred 64-bit syscall for the case where the kernel provides 64-bit time_t syscalls *and* also a 32-bit vDSO (in this case the *64-bit* syscall should be preferable over the vDSO). All architectures that provides 32-bit vDSO (i386, mips, powerpc, s390) modulo sparc; but I am not sure if some kernels versions do provide only 32-bit vDSO while still providing 64-bit time_t syscall. Regardless, for such cases the 64-bit time_t syscall is used if the vDSO returns overflowed 32-bit time_t. Tested on i686-linux-gnu (with a time64 and non-time64 kernel), x86_64-linux-gnu. Built with build-many-glibcs.py. Co-authored-by: Florian Weimer <fweimer@redhat.com>
2021-06-22linux: Remove supports_time64 () from clock_gettimeAdhemerval Zanella
It breaks the usage case of live migration like CRIU or similar. The performance drawback is it would require an extra syscall on older kernels without 64-bit time support. Checked on i686-linux-gnu on a 4.15 kernel and on a 5.11 kernel (with and without --enable-kernel=5.1) and on x86_64-linux-gnu. Reviewed-by: Lukasz Majewski <lukma@denx.de>

2020-08-24linux: Simplify clock_gettimeAdhemerval Zanella
With arch-syscall.h it can now assumes the existance of either __NR_clock_gettime or __NR_clock_gettime_time64. The 32-bit time_t support is now only build for !__ASSUME_TIME64_SYSCALLS. It also uses the time64-support functions to simplify it further. Checked on x86_64-linux-gnu and i686-linux-gnu (on 5.4 and on 4.15 kernel).
2020-03-23y2038: fix: Add missing libc_hidden_def attribute for some syscall wrappersLukasz Majewski
During the conversion to support 64 bit time on some architectures with __WORDSIZE == 32 && __TIMESIZE != 64 the libc_hidden_def attribute for eligible functions was by mistake omitted. This patch fixes this issue and exports (and allows using) those functions when Y2038 support is enabled in glibc.
2020-01-03linux: Optimize fallback 32-bit clock_gettimeAdhemerval Zanella
This patch avoid probing the __NR_clock_getttime64 syscall each time __clock_gettime64 is issued on a kernel without 64 bit time support. Once ENOSYS is obtained, only 32-bit clock_gettime are used. The following snippet: clock_gettime (CLOCK_REALTIME, &(struct timespec) { 0 }); clock_gettime (CLOCK_MONOTONIC, &(struct timespec) { 0 }); clock_gettime (CLOCK_BOOTTIME, &(struct timespec) { 0 }); clock_gettime (20, &(struct timespec) { 0 }); On a kernel without 64 bit time support and with vDSO support results on the following syscalls: syscall_0x193(0, 0xff87ba30, [...]) = -1 ENOSYS (Function not implemented) clock_gettime(CLOCK_BOOTTIME, {tv_sec=927082, tv_nsec=474382032}) = 0 clock_gettime(0x14 /* CLOCK_??? */, 0xff87b9f8) = -1 EINVAL (Invalid argument) While on a kernel without vDSO support: syscall_0x193(0, 0xbec95550, 0xb6ed2000, 0x1, 0xbec95550, 0) = -1 (errno 38) clock_gettime(CLOCK_REALTIME, {tv_sec=1576615930, tv_nsec=638250162}) = 0 clock_gettime(CLOCK_MONOTONIC, {tv_sec=1665478, tv_nsec=638779620}) = 0 clock_gettime(CLOCK_BOOTTIME, {tv_sec=1675418, tv_nsec=292932704}) = 0 clock_gettime(0x14 /* CLOCK_??? */, 0xbec95530) = -1 EINVAL (Invalid argument) Checked on i686-linux-gnu on 4.15 kernel and on a 5.3 kernel.

2020-01-03linux: Add support for clock_gettime64 vDSOAdhemerval Zanella
No architecture currently defines the vDSO symbol. On architectures with 64-bit time_t the HAVE_CLOCK_GETTIME_VSYSCALL is renamed to HAVE_CLOCK_GETTIME64_VSYSCALL, it simplifies clock_gettime code. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
2020-01-03linux: Fix vDSO macros build with time64 interfacesAdhemerval Zanella
As indicated on libc-help [1] the ec138c67cb commit broke 32-bit builds when configured with --enable-kernel=5.1 or higher. The scenario 10 from [2] might also occur in this configuration and INLINE_VSYSCALL will try to use the vDSO symbol and HAVE_CLOCK_GETTIME64_VSYSCALL does not set HAVE_VSYSCALL prior its usage. Also, there is no easy way to just enable the code to use one vDSO symbol since the macro INLINE_VSYSCALL is redefined if HAVE_VSYSCALL is set. Instead of adding more pre-processor handling and making the code even more convoluted, this patch removes the requirement of defining HAVE_VSYSCALL before including sysdep-vdso.h to enable vDSO usage. The INLINE_VSYSCALL is now expected to be issued inside a HAVE_*_VSYSCALL check, since it will try to use the internal vDSO pointers. Both clock_getres and clock_gettime vDSO code for time64_t were removed since there is no vDSO setup code for the symbol (an architecture can not set HAVE_CLOCK_GETTIME64_VSYSCALL). Checked on i686-linux-gnu (default and with --enable-kernel=5.1), x86_64-linux-gnu, aarch64-linux-gnu, and powerpc64le-linux-gnu. I also checked against a build to mips64-linux-gnu and sparc64-linux-gnu.

2019-09-04Finish move of clock_* functions to libc. [BZ #24959]Zack Weinberg
In glibc 2.17, the functions clock_getcpuclockid, clock_getres, clock_gettime, clock_nanosleep, and clock_settime were moved from librt.so to libc.so, leaving compatibility stubs behind. Now that the dynamic linker no longer insists on finding versioned symbols in the same library that originally defined them, we do not need the stubs anymore, and this means we don't need GLIBC_PRIVATE __-prefix aliases for most of the functions anymore either. (clock_gettime still needs one.) For ports added before 2.17, libc.so needs to provide two symbol versions for each, the default at GLIBC_2.17 plus a compat version matching what librt had. While I'm at it, move the clock_*.c files and their tests from rt/ to time/.

2015-05-26Consolidate vDSO macros and usageAdhemerval Zanella
This patch consolidate the Linux vDSO define and usage across all ports that uses it. The common vDSO definitions and calling through {INLINE/INTERNAL}_VSYSCALL macros are moved to a common header sysdep-vdso.h and vDSO name declaration and prototype is defined using a common macro. Also PTR_{MANGLE,DEMANGLE} is added to ports that does not use them for vDSO calls (aarch64, powerpc, s390, and tile) and thus it will reflect in code changes. For ports that already implement pointer mangling/demangling in vDSO system (i386, x32, x86_64) this patch is mainly a code refactor. Checked on x32, x86_64, x32, ppc64le, and aarch64.
