curr_cmd points to the command that is in processing or waiting for its command response from firmware. If the function shutdown happens to occur at this time we should cancel the cmd timer and put the command back to free queue. Cc: <stable@vger.kernel.org> # 3.8 Tested-by:

Running the following script repeatedly on XO-4 with SD8787 produces command timeout and system lockup. insmod mwifiex_sdio.ko sleep 1 ifconfig eth0 up iwlist eth0 scan & sleep 0.5 rmmod mwifiex_sdio mwifiex_send_cmd_async() is called for sync as well as async commands. (mwifiex_send_cmd_sync() internally calls it for sync command.) "adapter->cmd_queued" gets filled inside mwifiex_send_cmd_async() routine for both types of commands. But it is used only for sync commands in mwifiex_wait_queue_complete(). This could lead to a race when two threads try to queue a sync command with another sync/async command simultaneously. Get rid of global variable and pass command node as a parameter to mwifiex_wait_queue_complete() to fix the problem. Cc: <stable@vger.kernel.org> # 3.8 Reported-by:

The beacon and multicast-buffer queues are managed by the beacon tasklet, and the generic tx path hang check does not help in any way here. Running it on those queues anyway can introduce some race conditions leading to unnecessary chip resets. Cc: stable@vger.kernel.org Signed-off-by:

The commit 'ath9k_hw: fix calibration issues on chainmask that don't include chain 0' changed the hardware chainmask to the chip chainmask for the duration of the calibration, but the revert to user configuration in the reset path runs too early. That causes some issues with limiting the number of antennas (including spurious failure in hardware-generated packets). Fix this by reverting the chainmask after the essential parts of the calibration that need the workaround, and before NF calibration is run. Signed-off-by:

Whenever an adapter is removed we must clean all the local structures, especially the timers and scheduled work. Otherwise those asynchronous threads will eventually try to access the freed nfc_dev pointer if an LLCP link is up. Signed-off-by: -

This is really difficult to test with real NFC devices, but without this fix an LLCP server will eventually refuse new connections. Signed-off-by:

John W. Linville says: ==================== This time just passing along a big batch of fixes from Johannes... For the mac80211 bits: "Here I have fixes from Ben Greear for stray work items when deleting interfaces, another idle handling fix from Felix, a fix from Marco ro a mesh PS buffering crash and I have a fix for the VHT MCS calculation in association request frames and more nl80211 feature advertising removal as well as a workaround to increase the dump size if the SKB overhead is too large. For 3.10 I already have a complete fix queued, but that also requires (simple) userspace changes." And for the iwlwifi bits: "The patches from Dor fix a bunch of calibration issues in the new MVM driver, and Emmanuel has a number of fixes there as well. Also, we decided to disable 8k A-MSDU by default, so that's in there. My own patches are addressing an issue we found with the new devices but that seems to also exist on older ones, the DMA writeback the devices do can be delayed and cause issues. The fix is unfortunately relatively large and depends on two other changes (to not be hugely conflicting), but I think it's still worth it at this point." As Johannes says, it is a bit large. But I hope it is still early enough in the cycle to make that worthwhile. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

The SLIPORT_SEMAPHORE register shadowed in the config-space may not reflect the correct POST stage after an EEH reset in BE2/3; it may return FW_READY state even though FW is not ready. This causes the driver to prematurely poll the FW mailbox and fail. For BE2/3 use the CSR-BAR/0xac instead. Reported-by:

Ben Hutchings says: ==================== Fix regressions introduced by the last set of fixes (sorry): 1. Potential deadlock when disabling TX queues. 2. RX was broken on architectures other than x86 and powerpc. I still expect to send one more bug fix for 3.9, but as it sometimes takes days to reproduce the bug it's going to take a couple of weeks of testing to be confident that it's really fixed. ==================== Signed-off-by: -

RX DMA buffers start at an offset of EFX_PAGE_IP_ALIGN bytes from the start of a cache line. This offset obviously needs to be included in the virtual address, but this was missed in commit b590ace0 ('sfc: Fix efx_rx_buf_offset() in the presence of swiotlb') since EFX_PAGE_IP_ALIGN is equal to 0 on both x86 and powerpc.

efx_device_detach_sync() locks all TX queues before marking the device detached and thus disabling further TX scheduling. But it can still be interrupted by TX completions which then result in TX scheduling in soft interrupt context. This will deadlock when it tries to acquire a TX queue lock that efx_device_detach_sync() already acquired. To avoid deadlock, we must use netif_tx_{,un}lock_bh(). Signed-off-by: -

While PCI card faces EEH errors, reset (usually hot reset) is expected to recover from the EEH errors. After EEH core finishes the reset, the driver callback (be_eeh_reset) is called and wait the firmware to complete POST successfully. The original code would return with error once detecting failure during POST stage. That seems not enough. The patch forces the driver (be_eeh_reset) to wait the firmware completes POST until timeout, instead of returning error upon detection POST failure immediately. Also, it would improve the reliability of the EEH funtionality of the driver. Signed-off-by:

When a router forwards a packet that contains the IPv4 timestamp option, if there is no space left in the option for the router to add its own timestamp, then the router increments the Overflow value in the option. However, if the addresses of the routers are prespecified in the option, then the overflow condition cannot happen: the option is structured so that each prespecified router has a place to write its timestamp. Other routers do not add a timestamp, so there will never be a lack of space. This fix ensures that the Overflow value in the IPv4 timestamp option is not incremented when the addresses of the routers are prespecified, even if the Pointer value is greater than the Length value.

We should reset nf settings bond to the skb as ipip/ipgre do. If not, the conntrack/nat info bond to the origin packet may continually redirect the packet to vxlan interface causing a routing loop. this is the scenario: VETP VXLAN Gateway /----\ /---------------\ | | | | | vx+--+vx --NAT-> eth0+--> Internet | | | | \----/ \---------------/ when there are any packet coming from internet to the vetp, there will be lots of garbage packets coming out the gateway's vxlan interface, but none actually sent to the physical interface, because they are redirected back to the vxlan interface in the postrouting chain of NAT rule, and dmesg complains: Mar 1 21:52:53 debian kernel: [ 8802.997699] Dead loop on virtual device vxlan0, fix it urgently!

QFQ+ can select for service only 'eligible' aggregates, i.e., aggregates that would have started to be served also in the emulated ideal system. As a consequence, for QFQ+ to be work conserving, at least one of the active aggregates must be eligible when it is time to choose the next aggregate to serve. The set of eligible aggregates is updated through the function qfq_update_eligible(), which does guarantee that, after its invocation, at least one of the active aggregates is eligible. Because of this property, this function is invoked in qfq_deactivate_agg() to guarantee that at least one of the active aggregates is still eligible after an aggregate has been deactivated. In particular, the critical case is when there are other active aggregates, but the aggregate being deactivated happens to be the only one eligible. However, this precaution is not needed for QFQ+ to be work conserving, because update_eligible() is always invoked also at the beginning of qfq_choose_next_agg(). This patch removes the additional invocation of update_eligible() in qfq_deactivate_agg(). Signed-off-by:

By definition of (the algorithm of) QFQ+, the system virtual time must be pushed up only if there is no 'eligible' aggregate, i.e. no aggregate that would have started to be served also in the ideal system emulated by QFQ+. QFQ+ serves only eligible aggregates, hence the aggregate currently in service is eligible. As a consequence, to decide whether there is no eligible aggregate, QFQ+ must also check whether there is no aggregate in service. Signed-off-by:
