[PATCH 3/4] sigaltstack: implement SS_AUTODISARM flag

This patch implements the SS_AUTODISARM flag that can be ORed with SS_ONSTACK when forming ss_flags. When this flag is set, sigaltstack will be disabled when entering the signal handler; more precisely, after saving sas to uc_stack. When leaving the signal handler, the sigaltstack is restored by

[PATCH 2/4] sigaltstack: preparations for adding new SS_xxx flags

This patch adds SS_FLAG_BITS - the mask that splits sigaltstack mode values and bit-flags. Since there is no bit-flags yet, the mask is defined to 0. The flags are added by subsequent patches. With every new flag, the mask should have the appropriate bit cleared. This makes sure if some flag is

[PATCH 4/4] selftests: Add test for sigaltstack(SS_ONSTACK | SS_AUTODISARM)

sigaltstack needs to be disabled before the signal handler can safely use swapcontext(). This patch adds the SS_AUTODISARM flag. This flag disables the sigaltstack when entering the signal handler. When returning from signal handler, the sigaltstack is restored by uc_stack. CC: Shuah Khan

[PATCH 4/4] selftests: Add test for sigaltstack(SS_ONSTACK|SS_AUTODISARM)

This patch adds the test case for SS_AUTODISARM flag. The test-case tries to set SS_AUTODISARM flag and checks if the nested signal corrupts the stack after swapcontext(). CC: Shuah Khan CC: linux-kernel@vger.kernel.org CC: linux-...@vger.kernel.org CC: Andy Lutomirski
