If in nr_link_failed the neighbour list is non-empty but the node list is empty we'll end dereferencing a in a NULL pointer. This fixes coverity 362. Signed-off-by:

The netpoll system currently has a rx to tx path via: netpoll_rx __netpoll_rx arp_reply netpoll_send_skb dev->hard_start_tx This rx->tx loop places network drivers at risk of inadvertently causing a deadlock or BUG halt by recursively trying to acquire a spinlock that is used in both their rx and tx paths (this problem was origionally reported to me in the 3c59x driver, which shares a spinlock between the boomerang_interrupt and boomerang_start_xmit routines). This patch breaks this loop, by queueing arp frames, so that they can be responded to after all receive operations have been completed. Tested by myself and the reported with successful results. Specifically it was tested with netdump. Heres the BZ with details: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=194055Signed-off-by:Neil Horman <nhorman@tuxdriver.com> Acked-by:

skb_find_text takes a "to" argument which is supposed to limit how far into the skb it will search for the given text. At present, it seems to ignore that argument on the first skb, and instead return a match even if the text occurs beyond the limit. Patch below fixes this, after adjusting for the "from" starting point. This consequently fixes the netfilter string match's "--to" handling, which currently is broken. Signed-off-by:

Fix 2 problems in dev_hard_start_xmit(): 1. nskb->next needs to link back to skb->next if hard_start_xmit() returns non-zero. 2. Since the total number of GSO fragments may exceed MAX_SKB_FRAGS + 1, it needs to stop transmitting if the netif_queue is stopped. Signed-off-by:

Fix checksum problems in the GSO code path for CHECKSUM_HW packets. The ipv4 TCP pseudo header checksum has to be adjusted for GSO segmented packets. The adjustment is needed because the length field in the pseudo-header changes. However, because we have the inequality oldlen > newlen, we know that delta = (u16)~oldlen + newlen is still a 16-bit quantity. This also means that htonl(delta) + th->check still fits in 32 bits. Therefore we don't have to use csum_add on this operations. This is based on a patch by Michael Chan <mchan@broadcom.com>. Signed-off-by:

This change improves an earlier change which replaced the large local variable arrays used during broadcasting with dynamically allocated arrays. The temporary arrays are now incoprorated into the multicast link data structure. Signed-off-by:

Incorporates several related fixes: - switchover now occurs when switching from an active link to a standby link - failure of a standby link no longer initiates switchover - links now display correct # of received packtes following reactivation Signed-off-by:

This change provides user-friendly feedback when TIPC is unable to perform certain configuration operations that don't work properly in certain modes. (In particular, any reconfiguration request that would temporarily take TIPC from network mode to standalone mode, or from standalone mode to not running mode, is disallowed.) Signed-off-by:

This fixes a bug spotted by the coverity checker, bug id #366. If (mod(seqno - prev) != 1) we set buf to NULL, dereference it in the for case, and set it to whatever value happes to be at adress 0+next, if it happens to be non-zero, we even stay in the loop. It seems that the author intended to break there. Signed-off-by:

This fix prevents link flopping and name table inconsistency problems arising when a node is assigned a different <Z.C.N> value than it used previously. (Changing the <Z.C.N> value causes other nodes to have two link endpoints sending to the same MAC address using two different destination <Z.C.N> values, requiring the receiving node to filter out the unwanted messages.)
