David Howells 9ad0830f30 [PATCH] Keys: Fix key serial number collision handling ... Fix the key serial number collision avoidance code in key_alloc_serial(). This didn't use to be so much of a problem as the key serial numbers were allocated from a simple incremental counter, and it would have to go through two billion keys before it could possibly encounter a collision. However, now that random numbers are used instead, collisions are much more likely. This is fixed by finding a hole in the rbtree where the next unused serial number ought to be and using that by going almost back to the top of the insertion routine and redoing the insertion with the new serial number rather than trying to be clever and attempting to work out the insertion point pointer directly. This fixes kernel BZ #7727. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		18 years ago
