Pull networking fixes from David Miller: "Some more fixes trickled in over the past few days: 1) PIM device names can overflow the IFNAMSIZ buffer unless we properly limit the allowed indexes, fix from Eric Dumazet. 2) Under heavy load we can OOPS in icmp reply processing due to an unchecked inet_putpeer() call. Fix from Neal Cardwell. 3) SCTP round trip calculations need to use 64-bit math to avoid overflows, fix from Schoch Christian. 4) Fix a memory leak and an error return flub in SCTP and IRDA triggerable by userspace. Fix from Tommi Rantala and found by the syscall fuzzer (trinity). 5) MLX4 driver gives bogus size to memcpy() call, fix from Amir Vadai. 6) Fix length calculation in VHOST descriptor translation, from Michael S Tsirkin. 7) Ambassador ATM driver loops forever while loading firmware, fix from Dan Carpenter. 8) Over MTU packets in openvswitch warn about wrong device, fix from Jesse Gross. 9) Netfilter IPSET's netlink code can overrun a string buffer because it's not properly limited to IFNAMSIZ. Fix from Florian Westphal. 10) PCAN USB driver sets wrong timestamp in SKB, from Oliver Hartkopp. 11) Make sure the RX ifindex always has a valid value in the CAN BCM driver, even if we haven't received a frame yet.

John W. Linville says: ==================== This pull request is intended for the 3.8 stream. It is a bit large -- I guess Thanksgiving got me off track! At least the code got to spend some time in linux-next... :-) This includes the usual batch of pulls for Bluetooth, NFC, and mac80211 as well as iwlwifi. Also here is an ath6kl pull, and a new driver in the rtlwifi family. The brcmfmac, brcmsmac, ath9k, and mwl8k get their usual levels of attention, and a handful of other updates tag along as well. For more detail on the pulls, please see below... On Bluetooth, Gustavo says: "Another set of patches for integration in wireless-next. There are two big set of changes in it: Andrei Emeltchenko and Mat Martineau added more patches towards a full Bluetooth High Speed support and Johan Hedberg improve the single mode support for Bluetooth dongles. Apart from that we have small fixes and improvements." ...and: "A few patches to 3.8. The majority of the work here is from Andrei on the High Speed support. Other than that Johan added support for setting LE advertising data. The rest are fixes and clean ups and small improvements like support for a new broadcom hardware." On mac80211, Johannes says: "This is for mac80211, for -next (3.8). Plenty of changes, as you can see below. Some fixes for previous changes like the export.h include, the beacon listener fix from Ben Greear, etc. Overall, no exciting new features, though hwsim does gain channel context support for people to try it out and look at." ...and...: "This one contains the mac80211-next material. Apart from a few small new features and cleanups I have two fixes for the channel context code. The RX_END timestamp support will probably be reworked again as Simon Barber noted the calculations weren't really valid, but the discussions there are still going on and it's better than what we had before." ...and: "Please pull (see below) to get the following changes: * a fix & a debug aid in IBSS from Antonio, * mesh cleanups from Marco, * a few bugfixes for some of my previous patches from Arend and myself, * and the big initial VHT support patchset" And on iwlwifi, Johannes says: "In addition to the previous four patches that I'm not resending, we have a number of cleanups, message reduction, firmware error handling improvements (yes yes... we need to fix them instead) and various other small things all over." ...and: "In his quest to try to understand the current iwlwifi problems (like stuck queues etc.) Emmanuel has first cleaned up the PCIe code, I'm including his changes in this pull request. Other than that I only have a small cleanup from Sachin Kamat to remove a duplicate include and a bugfix to turn off MFP if software crypto is enabled, but this isn't really interesting as MFP isn't supported right now anyway." On NFC, Samuel says: "With this one we have: - A few HCI improvements in preparation for an upcoming HCI chipset support. - A pn544 code cleanup after the old driver was removed. - An LLCP improvement for notifying user space when one peer stops ACKing I frames." On ath6kl, Kalle says: "Major changes this time are firmware recover support to gracefully handle if firmware crashes, support for changing regulatory domain and support for new ar6004 hardware revision 1.4. Otherwise there are just smaller fixes or cleanups from different people." Thats about it... :-) Please let me know if there are problems! ==================== Signed-off-by: NDavid S.

This patch reports the change made by Stephen Hemminger in ipip and gre[6] in commit eccc1bb8 (tunnel: drop packet if ECN present with not-ECT). Goal is to handle RFC6040, Section 4.2: Default Tunnel Egress Behaviour. o If the inner ECN field is Not-ECT, the decapsulator MUST NOT propagate any other ECN codepoint onwards. This is because the inner Not-ECT marking is set by transports that rely on dropped packets as an indication of congestion and would not understand or respond to any other ECN codepoint [RFC4774]. Specifically: * If the inner ECN field is Not-ECT and the outer ECN field is CE, the decapsulator MUST drop the packet. * If the inner ECN field is Not-ECT and the outer ECN field is Not-ECT, ECT(0), or ECT(1), the decapsulator MUST forward the outgoing packet with the ECN field cleared to Not-ECT. The patch takes benefits from common function added in net/inet_ecn.h. Like it was done for Xin4 tunnels, it adds logging to allow detecting broken systems that set ECN bits incorrectly when tunneling (or an intermediate router might be changing the header). Errors are also tracked via rx_frame_error. CC: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: NNicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: NDavid S.

On BE2 chip, an interrupt may be raised even when EQ is in un-armed state. As a result be_intx()::events_get() and be_poll:events_get() can race and notify an EQ wrongly. Fix this by counting events only in be_poll(). Commit 0b545a62 fixes the same issue in the MSI-x path. But, on Lancer, INTx can be de-asserted only by notifying num evts. This is not an issue as the above BE2 behavior doesn't exist/has never been seen on Lancer. Signed-off-by: NSathya Perla <sathya.perla@emulex.com> Signed-off-by: NDavid S.

由 Michal Kubeček 提交于
If all slaves of a balance-rr bond with ARP monitor are enslaved with down link state, bond keeps down state even after slaves go up. This is caused by bond_enslave() setting curr_active_slave to first slave not taking into account its link state. As bond_loadbalance_arp_mon() uses curr_active_slave to identify whether slave's down->up transition should update bond's link state, bond stays down even if slaves are up (until first slave goes from up to down at least once). Before commit f31c7937 "bonding: start slaves with link down for ARP monitor", this was masked by slaves always starting in UP state with ARP monitor (and MII monitor not relying on curr_active_slave being NULL if there is no slave up).
