atl1c uses netdev_alloc_skb to refill its rx dma ring, but that call makes no guarantees about the suitability of the memory for use in DMA. As a result we've gotten reports of atl1c drivers occasionally hanging and needing to be reset: https://bugzilla.kernel.org/show_bug.cgi?id=54021 Fix this by modifying the call to use the internal version __netdev_alloc_skb, where you can set the gfp_mask explicitly to include GFP_DMA. Tested by two reporters in the above bug, who have the hardware to validate it. Both report immediate cessation of the problem with this patch Signed-off-by:

When (integer) sysctl values are expressed in ms and have to be represented internally as jiffies. The msecs_to_jiffies function returns an unsigned long, which gets assigned to the integer.

usbnet doesn't support yet SG, so drivers should not advertise SG or TSO capabilities, as they allow TCP stack to build large TSO packets that need to be linearized and might use order-5 pages. This adds an extra copy overhead and possible allocation failures. Current code ignore skb_linearize() return code so crashes are even possible. Best is to not pretend SG/TSO is supported, and add this again when/if usbnet really supports SG for devices who could get a performance gain.

John W. Linville says: ==================== This is another batch of fixes intended for the 3.11 stream. FWIW, this is the first request with fixes from the mac80211 and iwlwifi trees as well. Regarding the mac80211 bits, Johannes says: "Here I have a fix for RSSI thresholds in mesh, two minstrel fixes from Felix, an nl80211 fix from Michal and four various fixes I did myself." As for the iwlwifi bits, Johannes says: "Here I have a fix for debugfs directory creation (causing a spurious error message), two scanning fixes from David Spinadel, an LED fix and two patches related to a BA session problem that eventually caused firmware crashes from Emmanuel and a small BT fix for older devices as well as a workaround for a firmware problem with APs with very small beacon intervals from myself." Along with those: Arend van Spriel addresses a lock-up and a NULL pointer dereference in brcmfmac. Daniel Drake fixes an unhandled interrupt during device tear down in mwifiex. Larry Finger corrects a wil6210 build error. Oleksij Rempel fixes two ath9k_htc problems related to keeping the driver and firmware in sync. Solomon Peachy gives us a cw1200 fix to avoid an oops in monitor mode. ==================== Signed-off-by: -

The work queue is initialised in rtl_open (when the interface goes up), but canceled in rtl_remove_one (when the PCI device gets removed). If the network interface is not brought up, then the work queue struct is not initialised. When the device is removed, the attempt to cancel the uninitialised work queue causes a lockdep warning. This patch fixes the issue by moving cancel_work_sync to rtl_close (to match rtl_open). (Note that rtl_close is also called via unregister_netdev in rtl_remove_one.) Signed-off-by:

Daniel Drake authored
During tear down (e.g. mwifiex_sdio_remove during system suspend), mwifiex left IRQs enabled for a significant period of time when it was unable to handle them correctly. This caused interrupt storms and interfered with the bluetooth interface on the same SDIO card. Solve this by disabling interrupts at the point when they can no longer be handled correctly, which is at the start of mwifiex_remove_card(). For cleanliness, we now enable interrupts in the mwifiex_add_card() path, to be symmetrical with the disabling of interrupts. We also couple the registration of the sdio IRQ handler with the actual enable/disable of interrupts at the hardware level. I also removed a write to this register in mwifiex_init_sdio which seemed pointless and won't cause any ill effects now that we only register the SDIO IRQ handler when we are ready to accept interrupts. Includes some corrections from Amitkumar Karwar. Signed-off-by:

commit 9f00b2e7 ("bridge: only expire the mdb entry when query is received") added a nasty bug as an active timer can be reinitialized. setup_timer() must be done once, no matter how many time mod_timer() is called. br_multicast_new_group() is the right place to do this. Reported-by:

The veth device doesn't provide the vlan features, so TSO for example is disabled and that causes performance issues when using tagged traffic. The test topology looks like this: br0 br1 / \ / \ vnet veth0.10 ----- veth1.10 vnet VM VM The netperf results with current veth driver: MIGRATED TCP STREAM TEST from 192.168.1.1 () port 0 AF_INET to 192.168.1.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 10.01 2210.22 Now after applying the proposed patch: MIGRATED TCP STREAM TEST from 192.168.1.1 () port 0 AF_INET to 192.168.1.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 87380 16384 16384 10.00 13067.47 Signed-off-by:Flavio Leitner <fbl@redhat.com> Signed-off-by:
