Rules are actually pretty simple - dentry_open() + expects vfsmount and dentry to be pinned down and it either transfers + them into created struct file or drops them. Old code had been very + confused in that area - if dentry_open() had failed either in do_open() + or do_create(), we ended up dentry and mqueue_mnt dropped twice, once + by dentry_open() cleanup and then by sys_mq_open(). + . + Fix consists of making the rules for do_create() and do_open() + same as for dentry_open() and updating the sys_mq_open() accordingly; + that actually leads to more straightforward code and less work on + normal path. + . + Signed-off-by: Al Viro <aviro@redhat.com> + Signed-off-by: Linus Torvalds <torvalds@osdl.org> +Notes: + jmm> Discovered by Doug Chapman +Bugs: +upstream: released (2.6.15.2) +linux-2.6: released (2.6.15-4) +2.6.8-sarge-security: released (2.6.8-16sarge2) +2.4.27-sarge-security: N/A +2.4.19-woody-security: N/A +2.4.18-woody-security: N/A +2.4.17-woody-security: N/A +2.4.16-woody-security: N/A +2.4.17-woody-security-hppa: N/A +2.4.17-woody-security-ia64: N/A |
