-stable review patch. If anyone has any objections, please let us know. ------------------ From: James Morris There's a bug in the seqfile handling for /proc/net/ip6_flowlabel, where, after finding a flowlabel, the code will loop forever not finding any further flowlabels, first traversing the rest of the hash bucket then just looping. This patch fixes the problem by breaking after the hash bucket has been traversed. Note that this bug can cause lockups and oopses, and is trivially invoked by an unpriveleged user.
