This is done because list are a very used primitive structure all over the kernel and it's currently impossible to include other header files in this list.h without creating some circular dependencies. For example, list.h implements rcu-protected list and uses rcu_dereference() without including rcupdate.h. It actually compiles because users of rcu_dereference() are macros. Others RCU functions could be used too but aren't probably because of this. Therefore this patch creates rculist.h which includes rcupdates without to many changes/troubles.

This may lead to an endless loop: TCP conntrack repeatedly finds the old entry, but can not kill it itself since destruction is already in progress, but destruction in process context can not complete since TCP conntrack is keeping the CPU busy. Drop the packet in TCP conntrack if we can't kill the connection ourselves to avoid this.

Maybe some other nasty things, but we caught only the oops in gc so far. The solution is to disarm the ifp->timer before flushing the rt from it.

This patch adds several sanity checks that mainly prevent userspace apps to send broken content into the system that may be misinterpreted by some other userspace application.

| * | | | | bridge: fix use-after-free in br_cleanup_bridges()Patrick McHardy2008-07-03

This is not enough however, if one of the additionally unregistered devices is next in the list to the bridge device, it will get freed as well and the iteration continues on the freed element. Restart iteration after each bridge device removal from the beginning to fix this, similar to what rtnl_link_unregister() does.

So we shouldn't be resetting the write pointer as we reject the call. Also, we must add the two placeholder words here regardless of success of the unwrap, to ensure the output buffer is left in a consistent state for svcauth_gss_release(). This fixes a BUG() in svcauth_gss.c:svcauth_gss_release(). Thanks to Aime Le Rouzic for bug report, debugging help, and testing. Signed-off-by: J.
