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: NDavid S. Miller <davem@davemloft.net>

If we try to rmmod the driver for an interface while sockets with setsockopt(JOIN_ANYCAST) are alive, some refcounts aren't cleaned up and we get stuck on: unregister_netdevice: waiting for ens3 to become free. Usage count = 1 If we LEAVE_ANYCAST/close everything before rmmod'ing, there is no problem. We need to perform a cleanup similar to the one for multicast in addrconf_ifdown(how == 1).

由 Beniamino Galvani 提交于
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.

由 Sujith Manoharan 提交于
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.

With this in mind, it's possible for virtualization tools to try and configure a single ported VF through the "wrong" PF port.

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.

The sunvnet driver does not have an rmb() in the ring consumer corresponding to the wmb() in the producer. According to Documentation/memory-barriers.txt: "When dealing with CPU-CPU interactions, certain types of memory barrier should always be paired. A lack of appropriate pairing is almost certainly an error." In cases where an rmb() is not a no-op and a consumer is removing data from the ring while a producer is adding new entries, a load reorder would allow CPU1 CPU2 ---- ---- LOAD desc.size [e.g] STORE desc.size <wmb> set desc.hdr.state = VIO_DESC_READY LOAD desc.hdr.state [because VIO_DESC_READY, use old desc.size, already loaded out of order] [CPU2 has reordered apparently unrelated LOADs] To ensure other desc fields are not loaded before checking VIO_DESC_READY, we need an rmb() between the check and desc data accesses. I've also moved the viodbg() call to after the rmb() so that it, too, has current descriptor data even with reordering, which has the side effect that it won't print anything for descriptors that are not VIO_DESC_READY as before. That's a) probably a good thing, since the fields are not necessarily set and, b) better than adding another rmb() just for viodbg(). This would not be possible if strict-ordering is enforced, but then the memory barriers should be no-ops in that case.

Using the LQ table which is initially set according to the rssi could lead to EAPOLs being sent in high legacy rates like 54mbps. It's better to avoid sending EAPOLs in high rates as it reduces the chances of a successful 4-Way handshake.
