Anish Bhatt says: ==================== net: Fix randconfig errros in bnx2i/bnx2fc caused by IPV6 Just like CNIC bnx2i/bnx2fc also have their tristate dependent on IPV6, however using the same solution as CNIC can cause recursive dependecies during make. Based on suggestions by Randy Dunlap, SCSI_NETLINK now depends on NET instead of selecting NET. Second patch fixes the actual randconfig error.

Just like CNIC, tristate of these two modules is also dependent on IPV6. These need to be handled separately as they select CNIC, which can override tristate for CNIC from 'm' to 'y', which can cause build failures when ipv6 is compiled as a module even if CNIC's Kconfig will only 'm' or 'n' when ipv6 is compiled as a module.

commit 35b1de55 ("rdma/cxgb4: Fixes cxgb4 probe failure in VM when PF is exposed through PCI Passthrough") moved the code to check for SR-IOV PF[0..3] much further down in init_one() past the point where we allocate a (struct adapter) for PF[0..3]. As a result, we left four of these on ever module remove. Fix: Allocate adapter structure only for PF4 Signed-off-by:

As Toshiaki Makita pointed out, the BRIDGE_INPUT_SKB_CB will not be initialized in br_should_learn() as that function is called only from br_handle_local_finish(). That is an input handler for link-local ethernet traffic so it perfectly correct to check br->vlan_enabled here.

Vladislav Yasevich says: ==================== bridge: Two small fixes to vlan filtering code. This series corrects 2 small issues that I've ran across recently while doing more work with vlan filtering changes. ==================== Signed-off-by: -
Vlad Yasevich authored
Currently, it is possible to modify the vlan filter configuration to add pvid or untagged support. For example: bridge vlan add vid 10 dev eth0 bridge vlan add vid 10 dev eth0 untagged pvid The second statement will modify vlan 10 to include untagged and pvid configuration. However, it is currently impossible to go backwards bridge vlan add vid 10 dev eth0 untagged pvid bridge vlan add vid 10 dev eth0 Here nothing happens. This patch correct this so that any modifiers not supplied are removed from the configuration. Signed-off-by:

The bridge code checks if vlan filtering is enabled on both ingress and egress. When the state flip happens, it is possible for the bridge to currently be forwarding packets and forwarding behavior becomes non-deterministic. Bridge may drop packets on some interfaces, but not others. This patch solves this by caching the filtered state of the packet into skb_cb on ingress. The skb_cb is guaranteed to not be over-written between the time packet entres bridge forwarding path and the time it leaves it. On egress, we can then check the cached state to see if we need to apply filtering information. Signed-off-by:

The problem is that the slave is first linked and slave_cnt is incremented afterwards leading to a div by zero in the modes that use it as a modulus. What happens is that in bond_start_xmit() bond_has_slaves() is used to evaluate further transmission and it becomes true after the slave is linked in, but when slave_cnt is used in the xmit path it is still 0, so fetch it once and transmit based on that. Since it is used only in round-robin and XOR modes, the fix is only for them. Thanks to Eric Dumazet for pointing out the fault in my first try to fix this.

John W. Linville says: ==================== pull request: wireless 2014-09-11 Please pull this batch of fixes intended for the 3.17 stream: For the mac80211 bits, Johannes says: "Two more fixes for mac80211 - one of them addresses a long-standing issue that we only found when using vendor events more frequently; the other addresses some bad information being reported in userspace that people were starting to actually look at." For the iwlwifi bits, Emmanuel says: "I re-enable scheduled scan on firmware that contain the fix for the bug that Linus reported. A few trivial fixes: endianity issues, the same DTIM period fix that I did in mac80211. Eyal fixes a few issues we identified with EAPOL, we now send them just as if they were management frames, this solves interrop issues. Johannes has another set of trivial fixes, while Luca fixes the way we configure the filters in the firmware. Last but not least, a new device is added by Oren." Emmanuel was traveling, resulting in his pull to be a bit larger than I would have liked to see at this point. FWIW, I have asked Emmanuel to be much more strict for any more pull requests in this cycle. In addition to the above, Sujith Manoharan reverts an earlier ath9k patch. The earlier change was found to allow for the device to sleep too long and miss beacons. ==================== Signed-off-by: -

Beniamino Galvani authored
In the current implementation the cleaning of tx ring is done by the NAPI poll handler, which is scheduled after rx interrupts. Thus, in absence of received packets the reclaim of used tx buffers is never executed, blocking further transmission. This can be easily reproduced starting the transmission of a UDP flow with iperf, which blocks almost immediately because skbs are not returned to the stack and the socket send buffer becomes full. The patch enables tx interrupts so that the tx reclaim is scheduled after completed transmissions. Signed-off-by:

This reverts commit 09ebb810. ath9k_hw_set_sta_beacon_timers() configures AR_TIM_PERIOD with the beacon interval. Before this commit, the sleepduration was never greater than the beacon interval. But now, the behavior has changed. For example, with an AP that uses a beacon interval of 100: ath: phy9: next beacon 61128704 ath: phy9: beacon period 204800 ath: phy9: DTIM period 204800 If the sleepduration is calculated based on the listen time, then the bmiss threshold should also be changed since the HW would be in sleep state for a longer time, but that is not done currently. To avoid configuring a higher beacon interval based on the sleepduration, revert to the original behavior. Power consumption is not a problem since PS is disabled in ath9k anyway.

Linux manpage for recvmsg and sendmsg calls does not explicitly mention setting msg_namelen to 0 when msg_name passed set as NULL. When developers don't set msg_namelen member in msghdr, it might contain garbage value which will fail the validation check and sendmsg and recvmsg calls from kernel will return EINVAL. This will break old binaries and any code for which there is no access to source code. To fix this, we set msg_namelen to 0 when msg_name is passed as NULL from userland. Signed-off-by:
