This patch fixes a bug which would trigger the BUG_ON() at net/core/dev.c:4156. It was found that this was due to continuing processing in the current poll call even when the call to napi_reschedule failed, indicating the device was already on the polling list. This resulted in an extra call to napi_complete which triggered the BUG_ON(). This patch ensures that we only contine processing rotting packets in the current mal_poll call if we are not already on the polling list. Signed-off-by:

commit 3ab098df (virtio-net: don't respond to cpu hotplug notifier if we're not ready) tries to bypass the cpu hotplug notifier by checking the config_enable and does nothing is it was false.

time_after_eq() only works if the delta is < MAX_ULONG/2. For a 32bit Dom0, if netfront sends packets at a very low rate, the time between subsequent calls to tx_credit_exceeded() may exceed MAX_ULONG/2 and the test for timer_after_eq() will be incorrect. Credit will not be replenished and the guest may become unable to send packets (e.g., if prior to the long gap, all credit was exhausted). Use jiffies_64 variant to mitigate this problem for 32bit Dom0. Suggested-by:

When the bnx2x driver is rmmoded, if VFs of a given PF will be assigned to a VM then that PF will be unable to call `pci_disable_sriov()'. If for that same PF there would also exist unassigned VFs in the hypervisor, the result will be that after the removal there will still be virtual PCI functions on the hypervisor. If the bnx2x module were to be re-inserted, the result will be that the VFs on the hypervisor will be re-probed directly following the PF's probe, even though that in regular loading flow sriov is only enabled once PF is loaded. The probed VF will then try to access its bar, causing a PCI error as the HW is not in a state enabling such a request. This patch adds a missing disablement procedure to the PF's removal, one that sets registers viewable to the VF to indicate that the VFs have no permission to access the bar, thus resulting in probe errors instead of PCI errors.

Buffers for FW statistics were allocated at an inappropriate time; In a machine where the driver encounters problems allocating all of its queues, the driver would still create FW requests for the statistics of the non-existing queues. The wrong order of memory allocation could lead to zeroed statistics messages being sent, leading to fw assert in case function 0 was down. This changes the order of allocations, guaranteeing that statistic requests will only be generated for actual queues. Signed-off-by:

commit 6ff50cd5 ("tcp: gso: do not generate out of order packets") had an heuristic that can trigger a warning in skb_try_coalesce(), because skb->truesize of the gso segments were exactly set to mss. This breaks the requirement that skb->truesize >= skb->len + truesizeof(struct sk_buff); It can trivially be reproduced by : ifconfig lo mtu 1500 ethtool -K lo tso off netperf As the skbs are looped into the TCP networking stack, skb_try_coalesce() warns us of these skb under-estimating their truesize.

Patch ed08495c "tcp: use RTT from SACK for RTO" always re-arms RTO upon obtaining a RTT sample from newly sacked data. But technically RTO should only be re-armed when the data sent before the last (re)transmission of write queue head are (s)acked. Otherwise the RTO may continue to extend during loss recovery on data sent in the future. Note that RTTs from ACK or timestamps do not have this problem, as the RTT source must be from data sent before. The new RTO re-arm policy is 1) Always re-arm RTO if SND.UNA is advanced 2) Re-arm RTO if sack RTT is available, provided the sacked data was sent before the last time write_queue_head was sent.

On receiving a packet too big icmp error we check if our current cached dst_entry in the socket is still valid. This validation check did not care about the expiration of the (cached) route. The error path I traced down: The socket receives a packet too big mtu notification. It still has a valid dst_entry and thus issues the ip6_rt_pmtu_update on this dst_entry, setting RTF_EXPIRE and updates the dst.expiration value (which could fail because of not up-to-date expiration values, see previous patch). In some seldom cases we race with a) the ip6_fib gc or b) another routing lookup which would result in a recreation of the cached rt6_info from its parent non-cached rt6_info. While copying the rt6_info we reinitialize the metrics store by copying it over from the parent thus invalidating the just installed pmtu update (both dsts use the same key to the inetpeer storage). The dst_entry with the just invalidated metrics data would just get its RTF_EXPIRES flag cleared and would continue to stay valid for the socket. We should have not issued the pmtu update on the already expired dst_entry in the first placed. By checking the expiration on the dst entry and doing a relookup in case it is out of date we close the race because we would install a new rt6_info into the fib before we issue the pmtu update, thus closing this race. Not reliably updating the dst.expire value was fixed by the patch "ipv6: reset dst.expires value when clearing expire flag". Reported-by:

On receiving a packet too big icmp error we update the expire value by calling rt6_update_expires. This function uses dst_set_expires which is implemented that it can only reduce the expiration value of the dst entry. If we insert new routing non-expiry information into the ipv6 fib where we already have a matching rt6_info we only clear the RTF_EXPIRES flag in rt6i_flags and leave the dst.expires value as is. When new mtu information arrives for that cached dst_entry we again call dst_set_expires. This time it won't update the dst.expire value because we left the dst.expire value intact from the last update. So dst_set_expires won't touch dst.expires. Fix this by resetting dst.expires when clearing the RTF_EXPIRE flag. dst_set_expires checks for a zero expiration and updates the dst.expires. In the past this (not updating dst.expires) was necessary because dst.expire was placed in a union with the dst_entry *from reference and rt6_clean_expires did assign NULL to it. This split happend in ecd98837 ("ipv6: fix race condition regarding dst->expires and dst->from"). Reported-by:

Right now skb->data is passed to rx_hook() even if the skb has not been linearised and without giving rx_hook() a way to linearise it. Change the rx_hook() interface and make it accept the skb and the offset to the UDP payload as arguments. rx_hook() is also renamed to rx_skb_hook() to ensure that out of the tree users notice the API change. In this way any rx_skb_hook() implementation can perform all the needed operations to properly (and safely) access the skb data. Signed-off-by:

We need to disable the netconsole (enabled = 0) before setting nt->np.dev to NULL because otherwise we might still have users after the netpoll_cleanup() since nt->enabled is set afterwards and we can have a message which will result in a NULL pointer dereference. It is very easy to hit dereferences all over the netpoll_send_udp function by running the following two loops in parallel: while [ 1 ]; do echo 1 > enabled; echo 0 > enabled; done; while [ 1 ]; do echo 00:11:22:33:44:55 > remote_mac; done; (the second loop is to generate messages, it can be done by anything) We're safe to set nt->np.dev = NULL and nt->enabled = 0 with the spinlock since it's required in the write_msg() function.

From Eric W Biederman. 12) IPSEC policies can go away while a timer is still pending for them, add appropriate ref-counting to fix, from Steffen Klassert. 13) Fix mis-programming of FDR and RMCR registers on R8A7740 sh_eth chips, from Nguyen Hong Ky and Simon Horman. 14) MLX4 forgets to DMA unmap pages on RX, fix from Amir Vadai. 15) IPV6 GRE tunnel MTU upper limit is miscalculated, from Oussama Ghorbel. 16) Fix typo in fq_change(), we were assigning "initial quantum" to "quantum". From Eric Dumazet. 17) Set a more appropriate sk_pacing_rate for non-TCP sockets, otherwise FQ packet scheduler does not pace those flows properly. Also from Eric Dumazet. 18) rtlwifi miscalculates packet pointers, from Mark Cave-Ayland. 19) l2tp_xmit_skb() can be called from process context, not just softirq context, so we must always make sure to BH disable around it. From Eric Dumazet. 20) On qdisc reset, we forget to purge the RB tree of SKBs in netem packet scheduler. From Stephen Hemminger. 21) Fix info leak in farsync WAN driver ioctl() handler, from Dan Carpenter and Salva Peiró. 22) Fix PHY reset and other issues in dm9000 driver, from Nikita Kiryanov and Michael Abbott. 23) When hardware can do SCTP crc32 checksums, we accidently don't disable the csum offload when IPSEC transformations have been applied. From Fan Du and Vlad Yasevich. 24) Tail loss probing in TCP leaves the socket in the wrong congestion avoidance state. From Yuchung Cheng. 25) In CPSW driver, enable NAPI before interrupts are turned on, from Markus Pargmann. 26) Integer underflow and dual-assignment in YAM hamradio driver, from Dan Carpenter. 27) If we are going to mangle a packet in tcp_set_skb_tso_segs() we must unclone it. This fixes various hard to track down crashes in drivers where the SKBs ->gso_segs was changing right from underneath the driver during TX queueing. From Eric Dumazet. 28) Fix the handling of VLAN IDs, and in particular the special IDs 0 and 4095, in the bridging layer. From Toshiaki Makita. 29) Another info leak, this time in wanxl WAN driver, from Salva Peiró. 30) Fix race in socket credential passing, from Daniel Borkmann. 31) WHen NETLABEL is disabled, we don't validate CIPSO packets properly, from Seif Mazareeb. 32) Fix identification of fragmented frames in ipv4/ipv6 UDP Fragmentation Offload output paths, from Jiri Pirko. 33) Virtual Function fixes in bnx2x driver from Yuval Mintz and Ariel Elior. 34) When we removed the explicit neighbour pointer from ipv6 routes a slight regression was introduced for users such as IPVS, xt_TEE, and raw sockets. We mix up the users requested destination address with the routes assigned nexthop/gateway. From Julian Anastasov and Simon Horman. 35) Fix stack overruns in rt6_probe(), the issue is that can end up doing two full packet xmit paths at the same time when emitting neighbour discovery messages. From Hannes Frederic Sowa. 36) davinci_emac driver doesn't handle IFF_ALLMULTI correctly, from Mariusz Ceier. 37) Make sure to set TCP sk_pacing_rate after the first legitimate RTT sample, from Neal Cardwell. 38) Wrong netlink attribute passed to xfrm_replay_verify_len(), from Steffen Klassert. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (152 commits) ax88179_178a: Add VID:DID for Samsung USB Ethernet Adapter ax88179_178a: Correct the RX error definition in RX header Revert "bridge: only expire the mdb entry when query is received" tcp: initialize passive-side sk_pacing_rate after 3WHS davinci_emac.c: Fix IFF_ALLMULTI setup mac802154: correct a typo in ieee802154_alloc_device() prototype ipv6: probe routes asynchronous in rt6_probe netfilter: nf_conntrack: fix rt6i_gateway checks for H.323 helper ipv6: fill rt6i_gateway with nexthop address ipv6: always prefer rt6i_gateway if present bnx2x: Set NETIF_F_HIGHDMA unconditionally bnx2x: Don't pretend during register dump bnx2x: Lock DMAE when used by statistic flow bnx2x: Prevent null pointer dereference on error flow bnx2x: Fix config when SR-IOV and iSCSI are enabled bnx2x: Fix Coalescing configuration bnx2x: Unlock VF-PF channel on MAC/VLAN config error bnx2x: Prevent an illegal pointer dereference during panic bnx2x: Fix Maximum CoS estimation for VFs drivers: net: cpsw: fix kernel warn during iperf test with interrupt pacing ...

While this commit was a good attempt to fix issues occuring when no multicast querier is present, this commit still has two more issues: 1) There are cases where mdb entries do not expire even if there is a querier present. The bridge will unnecessarily continue flooding multicast packets on the according ports. 2) Never removing an mdb entry could be exploited for a Denial of Service by an attacker on the local link, slowly, but steadily eating up all memory. Actually, this commit became obsolete with "bridge: disable snooping if there is no querier" (b00589af) which included fixes for a few more cases. Therefore reverting the following commits (the commit stated in the commit message plus three of its follow up fixes): ==================== Revert "bridge: update mdb expiration timer upon reports." This reverts commit f144febd. Revert "bridge: do not call setup_timer() multiple times" This reverts commit 1faabf2a. Revert "bridge: fix some kernel warning in multicast timer" This reverts commit c7e8e8a8. Revert "bridge: only expire the mdb entry when query is received" This reverts commit 9f00b2e7. ==================== CC: Cong Wang <amwang@redhat.com> Signed-off-by:
