| |
2.6.32-stable review patch. If anyone has any objections, please let me know.
---------------- From: Jiri Slaby <jslaby@suse.cz>
commit 318f6b228ba88a394ef560efc1bfe028ad5ae6b6 upstream.
Do not set current->mm->mmap to NULL in 32-bit emulation on 64-bit load_aout_binary after flush_old_exec as it would destroy already set brpm mapping with arguments.
Introduced by b6a2fea39318e43fee84fa7b0b90d68bed92d2ba mm: variable length argument support where the argument mapping in bprm was added.
[ hpa: this is a regression from 2.6.22... time to kill a.out? ]
