| | | | | | | | | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines
* linux: Only use 64-bit syscall if required for timerfd_settimeAdhemerval Zanella2021-06-221-11/+14
| | | | | | | | | | | For !__ASSUME_TIME64_SYSCALLS there is no need to issue a 64-bit syscall if the provided timeout fits in a 32-bit one. The 64-bit usage should be rare since the timeout is a relative one. 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.

* linux: Simplify timerfd_settimeAdhemerval Zanella2020-08-241-14/+9
| | | | | | | | | | | With arch-syscall.h it can now assumes the existance of either __NR_timer_settime or __NR_time_settime_time64. The 32-bit time_t support is now only build for !__ASSUME_TIME64_SYSCALLS. Checked on x86_64-linux-gnu and i686-linux-gnu (on 5.4 and on 4.15 kernel). Reviewed-by: Lukasz Majewski <lukma@denx.de>
* y2038: linux: Provide __timerfd_settime64 implementationLukasz Majewski2020-02-021-0/+87
This patch replaces auto generated wrapper (as described in sysdeps/unix/sysv/linux/syscalls.list) for timerfd_settime with one which adds extra support for reading and writing from Linux kernel 64 bit time values on machines with __TIMESIZE != 64. There is no functional change for archs already supporting 64 bit time ABI. This patch is conceptually identical to timer_settime conversion already done in sysdeps/unix/sysv/linux/timer_settime.c. Please refer to corresponding commit message for detailed description of introduced functions and the testing procedure. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> --- Changes for v4: - Update date from 2019 to 2020 Changes for v3: - Add missing libc_hidden_def() Changes for v2: - Remove "Contributed by" from the file header - Remove early check for (fd < 0) in __timerfd_settime64 as the fd correctness check is already done in Linux kernel - Add single descriptive comment line to provide concise explanation of the code
