Setting net.ipv6.conf.<interface>.accept_ra=2 causes the kernel to accept RAs even when forwarding is enabled. However, enabling forwarding purges all default routes on the system, breaking connectivity until the next RA is received. Fix this by not purging default routes on interfaces that have accept_ra=2.

This is a resubmission. Added kfree() in ax88179_get_eeprom to prevent memory leakage. Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts. Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)". Fixed endianness issue on big endian systems and verified this driver on iBook G4. Removed steps that change net->features in ax88179_set_features function. Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array. Fixed the issue that the default MTU is not 1500. Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an MTU higher than 1500. Fixed indentation and empty line coding style errors. The _nopm version usb functions were added to access register in suspend and resume functions. Serveral variables allocted dynamically were removed and replaced by stack variables. ax88179_get_eeprom were modified from asix_get_eeprom in asix_common. This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0 to gigabit ethernet adapters. It's based on the AX88xxx driver but the usb commands used to access registers for AX88179 are completely different. This driver had been verified on x86 system with AX88179/AX88178A and Sitcomm LN-032 USB dongles. Signed-off-by:

I had a report recently of a user trying to use dropwatch to localise some frame loss, and they were getting false positives. Turned out they were using a user space SCTP stack that used raw sockets to grab frames. When we don't have a registered protocol for a given packet, we record it as a drop, even if a raw socket receieves the frame. We should only record the drop in the event a raw socket doesnt exist to receive the frames Tested by the reported successfully Signed-off-by:

John W. Linville says: ==================== This is another flurry of fixes intended for the 3.9 stream... A mac80211 pull from Johannes: "Seth fixes a stupid bug I introduced into one of his earlier patches, Chun-Yeow fixes mesh forwarding and Felix fixes monitor mode. I myself fixed a small locking issue and, the biggest change here, removed some nl80211 information with which sometimes the per wiphy information was getting too large for the typical 4k-minus-overhead. In my -next tree I have a patch to allow splitting that and add back the information removed now." An iwlwifi pull from Johannes: "I have a fix for a pretty important bug regarding DMA mapping, that could cause the DMA engine to overwrite data we wanted to send to it, so that the next time we send it it would be bad. This particularly affects calibration results. Other than that, three little fixes for the MVM driver." But wait, there's more! Avinash Patil fixes an incorrectly timed delay in mwifiex. Bing Zhao prevents a crash in SD8688 caused by failing to properly set a flag before issuing a command. Felix Fietkau is the big here this time, providing a trio of minor ath9k fixes and correcting the advertised interface combinations for rt2x00 when mesh support is disabled. Finally, Hauke Mehrtens gives us a patch that correctlin initializes a spin lock in the bcma code. Please let me know if there are problems! ==================== Signed-off-by: -

The sendmsg() syscall handler for PPPoL2TP doesn't decrease the socket reference counter after successful transmissions. Any successful sendmsg() call from userspace will then increase the reference counter forever, thus preventing the kernel's session and tunnel data from being freed later on. The problem only happens when writing directly on L2TP sockets. PPP sockets attached to L2TP are unaffected as the PPP subsystem uses pppol2tp_xmit() which symmetrically increase/decrease reference counters. This patch adds the missing call to sock_put() before returning from pppol2tp_sendmsg(). Signed-off-by:

Fix memory leak in phy_device_free() for the case when phy_device* returned by phy_device_create() is not registered in the system. Bug description: phy_device_create() sets name of kobject using dev_set_name(), which allocates memory using kvasprintf(), but this memory isn't freed if the underlying device isn't registered properly, because kobject_cleanup() is not called in that case. This can happen (and actually is happening on our machines) if phy_device_register(), called by mdiobus_scan(), fails. Patch description: Embedded struct device is initialized in phy_device_create() and it counterpart phy_device_free() just drops one reference to the device, which leads to proper deinitialization including releasing the kobject name memory.

TCP prequeue mechanism purpose is to let incoming packets being processed by the thread currently blocked in tcp_recvmsg(), instead of behalf of the softirq handler, to better adapt flow control on receiver host capacity to schedule the consumer. But in typical request/answer workloads, we send request, then block to receive the answer. And before the actual answer, TCP stack receives the ACK packets acknowledging the request. Processing pure ACK on behalf of the thread blocked in tcp_recvmsg() is a waste of resources, as thread has to immediately sleep again because it got no payload. This patch avoids the extra context switches and scheduler overhead.

Lee A. Roberts says: ==================== This series of patches resolves several SCTP association hangs observed during SCTP stress testing. Observable symptoms include communications hangs with data being held in the association reassembly and/or lobby (ordering) queues. Close examination of reassembly/ordering queues may show either duplicated or missing packets. In version #2, corrected build failure in initial version of patch series due to wrong calling sequence for sctp_ulpq_partial_delivery() being inserted in sctp_ulpq_renege(). In version #3, adjusted patch documentation to be less repetitive. ==================== Signed-off-by: -

In sctp_ulpq_tail_data(), use return values 0,1 to indicate whether a complete event (with MSG_EOR set) was delivered. A return value of -ENOMEM continues to indicate an out-of-memory condition was encountered. In sctp_ulpq_retrieve_partial() and sctp_ulpq_retrieve_first(), correct message reassembly logic for SCTP partial delivery. Change logic to ensure that as much data as possible is sent with the initial partial delivery and that following partial deliveries contain all available data. In sctp_ulpq_partial_delivery(), attempt partial delivery only if the data on the head of the reassembly queue is at or before the cumulative TSN ACK point. In sctp_ulpq_renege(), use the modified return values from sctp_ulpq_tail_data() to choose whether to attempt partial delivery or to attempt to drain the reassembly queue as a means to reduce memory pressure. Remove call to sctp_tsnmap_mark(), as this is handled correctly in call to sctp_ulpq_tail_data(). Signed-off-by:

For SD8688, FUNC_INIT command is queued before fw_ready flag is set. This causes the following crash as lbs_thread blocks any command if fw_ready is not set.

On many different chips, important aspects of the MAC state are not fully cleared by a warm reset. This can show up as tx/rx hangs, those annoying "DMA failed to stop in 10 ms..." messages or other quirks. On AR933x, the chip can occasionally get stuck in a way that only a driver unload/reload or a reboot would bring it back to life. With this patch, a full reset is issued when bringing the chip out of FULL-SLEEP state (after idle), or if either Rx or Tx was not shut down properly. This makes the DMA related error messages disappear completely in my tests on AR933x, and the chip does not get stuck anymore. Cc: stable@vger.kernel.org Signed-off-by:

The ath9k commit 2ef16755 (ath9k: fix signal strength reporting issues) fixed an issue where the reported per-frame signal strength reported to mac80211 was being overwritten with an internal average. The same issue is also present in ath9k_htc. In addition to preventing the driver from overwriting the value, this commit also ensures that the internal average (which is used for ANI) only tracks beacons of the AP that we're connected to.

RSSI is being stored internally as s8 in several places. The indication of an unset RSSI value, ATH_RSSI_DUMMY_MARKER, was supposed to have been set to 127, but ended up being set to 0x127 because of a code cleanup mistake. This could lead to invalid signal strength values in a few places. Signed-off-by:

This USB ethernet adapter was purchased in anodyne packaging from the computer store adjacent to linux.conf.au 2013 in Canberra (Australia). A web search shows other recent purchasers in Lancaster (UK) and Seattle (USA). Just like an emergent virus, our age of e-commerce and airmail allows underdocumented hardware to spread around the world instantly using the vector of ridiculously low prices. Paige Thompson, infected via eBay, discovered that the HG20F9 is a copy of the Asix 88772B; many viruses copy the RNA of other viruses. See Paige's work at <https://github.com/paigeadele/HG20F9>. This patch uses her discovery to update the restructured Asix driver in the current kernel. Just as some viruses inhabit seemingly-healthy cells, the HG20F9 uses the Vendor ID 0x066b assigned to Linksys Inc. For the present there is no clash of Product ID 0x20f9. Signed-off-by:
