| | | | | | | | | | | | | | | | | | | | htb_requeue() enqueues skbs for which htb_classify() returns NULL. This is wrong because such skbs could be handled by NET_CLS_ACT code, and the decision could be different than earlier in htb_enqueue().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While recevied ASCONF chunk with serial number less then needed, kernel will treat this chunk as a retransmitted ASCONF chunk and find cached ASCONF-ACK chunk used sctp_assoc_lookup_asconf_ack(). But this function will always return NO-NULL. So response with cached ASCONF-ACKs chunk will cause kernel panic. In function sctp_assoc_lookup_asconf_ack(), if the cached ASCONF-ACKs list asconf_ack_list is empty, or if the serial being requested does not exists, the function as it currectly stands returns the actuall list_head asoc->asconf_ack_list, this is not a cache ASCONF-ACK chunk but a bogus pointer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The family for iprange_mt4 should be AF_INET, not AF_INET6. Noticed by Jiri Moravec <jim.lkml@gmail.com>. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
| * | | [NETFILTER]: nf_conntrack: fix ct_extend ->move operationPatrick McHardy2008-02-072-4/+5

| * | | [NETFILTER]: nf_conntrack: TCP conntrack reopening fixJozsef Kadlecsik2008-02-071-6/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TCP connection tracking in netfilter did not handle TCP reopening properly: active close was taken into account for one side only and not for any side, which is fixed now. The patch includes more comments to explain the logic how the different cases are handled. The bug was discovered by Jeff Chua.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This merges the mux.c (including the connection interface) with trans_fd in preparation for transport API changes. Ultimately, trans_fd will need to be rewritten to clean it up and simplify the implementation, but this reorganization is viewed as the first step.

A spinlock seems like the right thing to be using since the idr functions go out of their way not to sleep. This patch eliminates the BUG by converting the semaphore to a spinlock.
