From e0f5fd87da61c6123467a8701e9c0dc5b528f3bf Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 30 Nov 2011 13:16:29 +0100 Subject: [PATCH] Fix sys_ipc/sys_semtimedop decoding on s390 The s390 kernel sys_ipc system call only takes five arguments instead of six arguments which the common code sys_ipc implementation takes. One of the arguments of the sys_semtimedop subcall is therefore passed in a different register than in the common code implementation. This leads to broken decoding of the timespec argument: semtimedop(0, 0x3ffffb43832, 1, {...}) = -1 EAGAIN Fixed it looks like this: semtimedop(0, 0x3ffffc2c842, 1, {0, 10000000}) = -1 EINTR * linux/ipc.c (sys_semtimedop): Fix timespec decoding on s390.
