From: Michael Braun <michael-dev@fami-braun.de> bridge: Fix br_forward crash in promiscuous mode It's a linux-next kernel from 2010-03-12 on an x86 system and it OOPs in the bridge module in br_pass_frame_up (called by br_handle_frame_finish) because brdev cannot be dereferenced (its set to a non-null value). Adding some BUG_ON statements revealed that BR_INPUT_SKB_CB(skb)->brdev == br-dev (as set in br_handle_frame_finish first) only holds until br_forward is called. The next call to br_pass_frame_up then fails. Digging deeper it seems that br_forward either frees the skb or passes it to NF_HOOK which will in turn take care of freeing the skb. The same is holds for br_pass_frame_ip. So it seems as if two independent skb allocations are required. As far as I can see, commit b33084be ("bridge: Avoid unnecessary clone on forward path") removed skb duplication and so likely causes this crash. This crash does not happen on 2.6.33. I've therefore modified br_forward the same way br_flood has been modified so that the skb is not freed if skb0 is going to be used and I can confirm that the attached patch resolves the issue for me.

Since all callers of br_mdb_ip_get need to check whether the hash table is NULL, this patch moves the check into the function. This fixes the two callers (query/leave handler) that didn't check it. Reported-by:

dccp: fix panic caused by failed initialisation This fixes a kernel panic reported thanks to Andre Noll: if DCCP is compiled into the kernel and any out of the initialisation steps in net/dccp/proto.c:dccp_init() fail, a subsequent attempt to create a SOCK_DCCP socket will panic, since inet{,6}_create() are not prevented from creating DCCP sockets. This patch fixes the problem by propagating a failure in dccp_init() to dccp_v{4,6}_init_net(), and from there to dccp_v{4,6}_init(), so that the DCCP protocol is not made available if its initialisation fails.

Registering/unregistering the Gigaset CAPI driver when a device is connected/disconnected causes an Oops when disconnecting two Gigaset devices in a row, because the same capi_driver structure gets unregistered twice.

When compiling this driver, the compiler throws the following warnings: drivers/isdn/hardware/eicon/message.c:8426: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8427: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8434: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8435: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8436: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8447: warning: array subscript is above array bounds This arises from the particular semantics the driver is using to write to the nlc array (static byte[256]). The array has a length in byte 0 followed by a T30_INFO struct starting at byte 1. The T30_INFO struct has a number of variable length strings after the station_id entry, which cannot be explicitly defined in the struct and the driver accesses them with an array index to station_id beyond the length of station_id. This patch merely changes the semantics that the driver uses to access the entries after the station_id entry to use the original 256 byte nlc array taking the offset and length of the station_id entry to calculate where to write in the array, thereby silencing the warning.

Access to fp->tx_bd_prod is protected by __netif_tx_lock, so we do not need any barrier for that. Update of fp->tx_bd_cons in bnx2x_tx_int() is not protected by lock, but barrier() nor smb_mb() in bnx2x_tx_avail() not guarantee we will see values that is written on other cpu. Ordering issues between netif_tx_stop_queue(), netif_tx_queue_stopped(), fp->tx_bd_cons = bd_cons and bnx2x_tx_avail() are already handled by smp_mb() in bnx2x_tx_int() and bnx2x_start_xmit().
