The patch titled Subject: ipc: fix potential oops when src msg > 4k w/ MSG_COPY has been removed from the -mm tree. Its filename was ipc-fix-potential-oops-when-src-msg-4k-w-msg_copy.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Peter Hurley <peter@xxxxxxxxxxxxxxxxxx> Subject: ipc: fix potential oops when src msg > 4k w/ MSG_COPY If the src msg is > 4k, then dest->next points to the next allocated segment; resetting it just prior to dereferencing is bad.
