From 8d4bd0ed0439dfc780aab801a085961925ed6838 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Tue, 8 Sep 2015 15:25:39 +0200 Subject: [PATCH] s390/compat: correct uc_sigmask of the compat signal frame The uc_sigmask in the ucontext structure is an array of words to keep the 64 signal bits (or 1024 if you ask glibc but the kernel sigset_t only has 64 bits). For 64 bit the sigset_t contains a single 8 byte word, but for 31 bit there are two 4 byte words. The compat signal handler code uses a simple copy of the 64 bit sigset_t to the 31 bit compat_sigset_t. As s390 is a big-endian architecture this is incorrect, the two words in the 31 bit sigset_t array need to be swapped.
