Apart from the mentioned oops, I observed another one one, triggered at irregular intervals via timer interrupt: run_timer_softirq -> dccp_keepalive_timer -> inet_csk_reqsk_queue_prune -> reqsk_free -> dccp_v6_reqsk_destructor The latter function is the problem and is also the last function to be called in said kernel panic. In any case, there is a real problem with allocating the right request_sock which is what this patch tackles. It fixes the following problem: - application listens on PF_INET6 - DCCPv4 packet comes in, is handed over to dccp_v4_do_rcv, from there to dccp_v4_conn_request Now: socket is PF_INET6, packet is IPv4. The following code then furnishes the connection with IPv6 - request_sock operations: req = reqsk_alloc(sk->sk_prot->rsk_prot); The first problem is that all further incoming packets will get a Reset since the connection can not be looked up. The second problem is worse: --> reqsk_alloc is called instead of inet6_reqsk_alloc --> consequently inet6_rsk_offset is never set (dangling pointer) --> the request_sock_ops are nevertheless still dccp6_request_ops --> destructor is called via reqsk_free --> dccp_v6_reqsk_destructor tries to free random memory location (inet6_rsk_offset not set) --> panic I have tested this for a while, DCCP sockets are now handled correctly in all three scenarios (v4/v6 only/v4-mapped). Commiter note: I've added the dccp_request_sock_ops forward declaration to keep the tree building and to reduce the size of the patch for 2.6.19, later I'll move the functions to the top of the affected source code to match what we have in the TCP counterpart, where this problem hasn't existed in the first place, dumb me not to have done the same thing on DCCP land 8) Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the INTC2 code contains a fixed IRQ table that it iterates through to set the handler type, we move this in to the CPU subtype setup code instead and allow for submitting the table that way. This drops the ST40 tables, as nothing has been happening with those processors, while converting the only existing users to use the new table directly (SH7760 and SH7780).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the recent change ripping out interrupt_table, explicit padding of the table was missing, causing bad things to happen when manually inserting handlers in to the table. This problem particularly showed up in relation to do_fpu_state_restore() which was inserted quite deeply in to the table and ended up scribbling over a slab object.

Aside this fixes a performance hog rendering access to /proc/cmdline very slow and resulting in a enough cache stalls for the 34K AP/SP programming model to make the bare metal code on the non-Linux VPE miss RT deadlines.

Found the problem, I believe: an object lesson in the need for great caution using ++. [...] @@ -213,6 +213,7 @@ static void ibmveth_replenish_buffer_poo } free_index = pool->consumer_index++ % pool->size; + pool->consumer_index = free_index; index = pool->free_map[free_index]; ibmveth_assert(index != IBM_VETH_INVALID_MAP); Since the ++ is used as post-increment, the increment is not included in free_index, and so the added line effectively reverts the increment. The produced_index side has an analagous bug. The following change corrects this: The recent commit 751ae21c6cd1493e3d0a4935b08fb298b9d89773 introduced a bug in the producer/consumer index calculation in the ibmveth driver - incautious use of the post-increment ++ operator resulted in an increment being immediately reverted. This patch corrects the logic. Without this patch, the driver oopses almost immediately after activation on at least some machines.
