pselect.c: Pass a pointer to SYSCALL_CANCEL [BZ #26606]
commit a92f4e6299fe0e3cb6f77e79de00817aece501ce
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date: Mon Jul 6 13:27:12 2020 -0300
linux: Add time64 pselect support
changed pselect.c to
r = SYSCALL_CANCEL (pselect6_time64, nfds, readfds, writefds, exceptfds,
timeout,
((__syscall_ulong_t[]){ (uintptr_t) sigmask,
__NSIG_BYTES }));
which doesn't work with x32's ARGIFY and data passed to syscall isn't
initialized with sigmask and __NSIG_BYTES. Change to
__syscall_ulong_t data[2] =
{
(uintptr_t) sigmask, __NSIG_BYTES
};
r = SYSCALL_CANCEL (pselect6_time64, nfds, readfds, writefds, exceptfds,
timeout, data);
fixes [BZ #26606].
