Fixes from RonQing Li. 10) Logitech Harmony 900 should be handled by zaurus driver not cdc_ether, update white lists and black lists accordingly. From Scott Talbert. 11) Receiving from certain kinds of devices there won't be a MAC header, so there is no MAC header to fixup in the IPSEC code, and if we try to do it we'll crash.

From Ben McKeegan. 17) Fix regression of ->ip_summed initialization in sfc driver. From Ben Hutchings. 18) Bluetooth timeout mistakenly using msecs instead of jiffies, from Andrzej Kaczmarek. 19) Using _sync variant of work cancellation results in deadlocks, use the non _sync variants instead. From Andre Guedes. 20) Bluetooth rfcomm code had reference counting problems leading to crashes, fix from Octavian Purdila. 21) The conversion of netem over to classful qdisc handling added two bugs to netem_dequeue(), fixes from Eric Dumazet. 22) Missing pci_iounmap() in ATM Solos driver. Fix from Julia Lawall. 23) b44_pci_exit() should not have __exit tag since it's invoked from non-__exit code. From Nikola Pajkovsky. 24) The conversion of the neighbour hash tables over to RCU added a race, fixed here by adding the necessary reread of tbl->nht, fix from Michel Machado. 25) When we added VF (virtual function) attributes for network device dumps, this potentially bloats up the size of the dump of one network device such that the dump size is too large for the buffer allocated by properly written netlink applications. In particular, if you add 255 VFs to a network device, parts of GLIBC stop working. To fix this, we add an attribute that is used to turn on these extended portions of the network device dump. Sophisticaed applications like 'ip' that want to see this stuff will be changed to set the attribute, whereas things like GLIBC that don't care about VFs simply will not, and therefore won't be busted by the mere presence of VFs on a network device. Thanks to the tireless work of Greg Rose on this fix. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (53 commits) sfc: Fix assignment of ip_summed for pre-allocated skbs ppp: fix 'ppp_mp_reconstruct bad seq' errors enic: Fix endianness bug. gre: fix spelling in comments netfilter: ctnetlink: fix soft lockup when netlink adds new entries (v2) Revert "netfilter: ctnetlink: fix soft lockup when netlink adds new entries" davinci_emac: Do not free all rx dma descriptors during init mlx4_core: Fixing array indexes when setting port types phy: IC+101G and PHY_HAS_INTERRUPT flag netdev/phy/icplus: Correct broken phy_init code ipsec: be careful of non existing mac headers Move Logitech Harmony 900 from cdc_ether to zaurus hso: memsetting wrong data in hso_get_count() netfilter: ip6_route_output() never returns NULL. ethernet/broadcom: ip6_route_output() never returns NULL. ipv6: ip6_route_output() never returns NULL. jme: Fix FIFO flush issue atm: clip: remove clip_tbl ipv4: ping: Fix recvmsg MSG_OOB error handling. rtnetlink: Fix problem with buffer allocation ...

| | * sfc: Fix assignment of ip_summed for pre-allocated skbsBen Hutchings2012-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When pre-allocating skbs for received packets, we set ip_summed = CHECKSUM_UNNCESSARY. We used to change it back to CHECKSUM_NONE when the received packet had an incorrect checksum or unhandled protocol. Commit bc8acf2c8c3e43fcc192762a9f964b3e9a17748b ('drivers/net: avoid some skb->ip_summed initializations') mistakenly replaced the latter assignment with a DEBUG-only assertion that ip_summed == CHECKSUM_NONE. This assertion is always false, but it seems no-one has exercised this code path in a DEBUG build. Fix this by moving our assignment of CHECKSUM_UNNECESSARY into efx_rx_packet_gro().

If the link is not ok, the skb is freed and no new dma descriptor added to the rx dma channel. This causes trouble during initialization when the carrier status has not yet been updated. If a lot of packets are received while netif_carrier_ok returns false, all dma descriptors are freed and the rx dma transfer is stopped. The bug occurs when the board is connected to a network with lots of traffic and the ifconfig down/up is done, e.g., when reconfiguring the interface with DHCP. The bug can be reproduced by flood pinging the davinci board while doing ifconfig eth0 down ifconfig eth0 up on the board. After that, the rx path stops working and the overrun value reported by ifconfig is counting up. This patch reverts commit 0a5f38467765ee15478db90d81e40c269c8dda20 and instead issues warnings only if cpdma_chan_submit returns -ENOMEM.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver attempts to use two TX rings but lacks proper support : 1) IRQ handler only takes care of TX completion on first TX ring 2) the stop/start logic uses the legacy functions (for non multiqueue drivers) This means all packets witk skb mark set to 1 are sent through high queue but are never cleaned and queue eventualy fills and block the device, triggering the infamous "NETDEV WATCHDOG" message. Lets use a single TX ring to fix the problem, this driver is not a real multiqueue one yet. Minimal fix for stable kernels.

Thanks to Eric Dumazet, Roland Dreier, and others. 2) Fix build failure when INET_UDP_DIAG is built in and ipv6 is modular. From Anisse Astier. 3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman. 4) ipv4 TCP reset generation needs to respect any network interface binding from the socket, otherwise route lookups might give a different result than all the other segments received. From Shawn Lu. 5) Fix unintended regression in ipv4 proxy ARP responses, from Thomas Graf. 6) Fix SKB under-allocation bug in sh_eth, from Yoshihiro Shimoda. 7) Revert skge PCI mapping changes that are causing crashes for some folks, from Stephen Hemminger. 8) IPV4 route lookups fill in the wildcarded fields of the given flow lookup key passed in, which is fine most of the time as this is exactly what the caller's want. However there are a few cases that want to retain the original flow key values afterwards, so handle those cases properly. Fix from Julian Anastasov. 9) IGB/IXGBE VF lookup bug fixes from Greg Rose. 10) Properly null terminate filename passed to ethtool flash device method, from Ben Hutchings. 11) S3 resume fix in via-velocity from David Lv. 12) Fix double SKB free during xmit failure in CAIF, from Dmitry Tarnyagin. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (72 commits) net: Don't proxy arp respond if iif == rt->dst.dev if private VLAN is disabled ipv4: Fix wrong order of ip_rt_get_source() and update iph->daddr. netprio_cgroup: fix wrong memory access when NETPRIO_CGROUP=m netprio_cgroup: don't allocate prio table when a device is registered netprio_cgroup: fix an off-by-one bug bna: fix error handling of bnad_get_flash_partition_by_offset() isdn: type bug in isdn_net_header() net: Make qdisc_skb_cb upper size bound explicit. ixgbe: ethtool: stats user buffer overrun ixgbe: dcb: up2tc mapping lost on disable/enable CEE DCB state ixgbe: do not update real num queues when netdev is going away ixgbe: Fix broken dependency on MAX_SKB_FRAGS being related to page size ixgbe: Fix case of Tx Hang in PF with 32 VFs ixgbe: fix vf lookup igb: fix vf lookup e1000: add dropped DMA receive enable back in for WoL gro: more generic L2 header check IPoIB: Stop lying about hard_header_len and use skb->cb to stash LL addresses zd1211rw: firmware needs duration_id set to zero for non-pspoll frames net: enable TC35815 for MIPS again ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current error handling doesn't work because we flash_part is a u32 so the checks for negative error codes don't work. I considered making things signed but I don't know the hardware enough to say if that's a problem. Really, we don't use the error codes so just returning zero for all problems is fine.

This occurs because the general practice in user space to query stats is to issue a ETHTOOL_GSSET cmd to learn the buffer size needed, allocate the buffer, then call ETHTOOL_GSTIRNGS and ETHTOOL_GSTATS. If the number of real_num_queues is changed or flow control attributes are changed after ETHTOOL_GSSET but before the ETHTOOL_GSTRINGS/ETHTOOL_GSTATS a user space buffer overrun occurs. To fix the overrun always return the max buffer size needed from get_sset_count() then return all strings and stats from get_strings()/get_ethtool_stats(). This _will_ change the output from the ioctl() call which could break applications and script parsing in theory. I believe these changes should not break existing tools because the only changes will be more {tx|rx}_queues and the {tx|rx}_pb_* stats will always be returned. Existing scripts already need to handle changing number of queues because this occurs today depending on system and current features. The {tx|rx}_pb_* stats are at the end of the output and should be handled by scripts today regardless. Finally get_ethtool_stats and get_strings are free-form outputs tools parsing these outputs should be defensive anyways. In the end these updates are better then having a tool segfault because of a buffer overrun.

Specifically it looks like that in 2.6.39 a change was made so that GRO would always have at least 16 frags available for coalescing, but the ixgbe RSC logic was not updated. As such the RSC feature would generate a frame larger than 64K and then overflow the value in the IP length field. To correct that I am now basing things on the PAGE_SIZE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When this GETHER controller received a large frame (about 1800 bytes or more), skb_over_panic() happened. This is because the previous driver set the RFLR to 0x1000 (4096 bytes) and the skb allocate size is smaller than 4096 bytes. So, the controller accepted such a frame. The controller can discard a large frame by the RFLR setting. So, the patch modifies the value of RFLR to mtu + ETH_HLEN + VLAN_HLEN + ETH_FCS_LEN.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We allocate memory for 'new_data' with kmalloc(). If we get the memory we then try to build_skb() and if that should fail (which it can) we do not enter 'if (likely(skb)) {' and actually use 'new_data' but instead fall through to the 'drop:' label and end up returning from the function without ever assigning 'new'data' to anything or freeing it. That leaks the memory allocated to 'new_data'. This patch fixes the memory leak by doing a kfree(new_data) in the case where build_skb() fails (or where allocation of 'new_data' itself fails, but in taht case it's just a harmless kfree(NULL)).
