Revision 342300cc9cd3428bc6bfe5809bfcc1b9a0f06702 authored by Martin Schwidefsky on 19 February 2016, 13:44:14 UTC, committed by Martin Schwidefsky on 22 February 2016, 08:29:35 UTC
git commit 8070361799ae1e3f4ef347bd10f0a508ac10acfb "s390: add support for vector extension" broke 31-bit compat processes in regard to signal handling. The restore_sigregs_ext32() function is used to restore the additional elements from the user space signal frame. Among the additional elements are the upper registers halves for 64-bit register support for 31-bit processes. The copy_from_user that is used to retrieve the high-gprs array from the user stack uses an incorrect length, 8 bytes instead of 64 bytes. This causes incorrect upper register halves to get loaded.
