From 566e10aa7292bacd74d229ca6f2cd9e8c8ba8748 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 12 Mar 2020 09:50:19 -0300 Subject: signal: Only handle on NSIG signals on signal functions (BZ #25657) The upper bits of the sigset_t s not fully initialized in the signal mask calls that return information from kernel (sigprocmask, sigpending, and pthread_sigmask), since the exported sigset_t size (1024 bits) is larger than Linux support one (64 or 128 bits). It might make sigisemptyset/sigorset/sigandset fail if the mask is filled prior the call. This patch changes the internal signal function to handle up to supported Linux signal number (_NSIG), the remaining bits are untouched. Checked on x86_64-linux-gnu and i686-linux-gnu. --- sysdeps/unix/sysv/linux/sigpending.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) (limited to 'sysdeps/unix/sysv/linux/sigpending.c') diff --git a/sysdeps/unix/sysv/linux/sigpending.c b/sysdeps/unix/sysv/linux/sigpending.c index f6bedb5182..458a3cf99e 100644 --- a/sysdeps/unix/sysv/linux/sigpending.c +++ b/sysdeps/unix/sysv/linux/sigpending.c @@ -15,13 +15,9 @@ License along with the GNU C Library; if not, see . */ -#include #include -#include - #include -#include - +#include /* Change the set of blocked signals to SET, wait until a signal arrives, and restore the set of blocked signals. */ -- cgit 1.4.1
