2014-04-24brcmfmac: Fix brcmf_chip_ai_coredisable not applying reset bits to BCMA_IOCTLHans de Goede1-2/+3
brcmfmac has been broken on my cubietruck with a BCM43362: brcmfmac: brcmf_chip_recognition: found AXI chip: BCM43362, rev=1 brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0: Apr 22 2013 14:50:00 version 5.90.195.89.6 FWID 01-b30a427d since commit 53036261033: "brcmfmac: update core reset and disable routines". The problem is that since this commit brcmf_chip_ai_resetcore no longer sets BCMA_IOCTL itself before bringing the core out of reset, instead relying on brcmf_chip_ai_coredisable to do so. But brcmf_chip_ai_coredisable is a nop of the chip is already in reset. This patch modifies brcmf_chip_ai_coredisable to always set BCMA_IOCTL even if the core is already in reset. This fixes brcmfmac hanging in firmware loading on my board.

The commit "ath9k: move sc_flags to ath_common" moved setting ATH_OP_INVALID flag below ieee80211_register_hw. This is causing the flag never being cleared randomly as the drv_start is called prior to setting flag. Fix this by setting the flag prior to register_hw.

2014-04-22ath9k: add a recv budgetTim Harvey1-0/+4
Implement a recv budget so that in cases of high traffic we still allow other taskets to get processed. Without this, we can encounter a host of issues during high wireless traffic reception depending on system load including rcu stall's detected (ARM), soft lockups, failure to service critical tasks such as watchdog resets, and triggering of the tx stuck tasklet. The same thing was proposed previously by Ben: http://www.spinics.net/lists/linux-wireless/msg112891.html The only difference here is that I make sure only processed packets are counted in the budget by checking at the end of the rx loop.

Despite having low legacy rates in the LQ table lower entries it doesn't help much in case we're doing aggregations as the aggregation was being transmitted in the initial rate of the table.

This gives better results when the attenuation increased signficantly (e.g. we got further from the AP) and after a while we start Tx Note that the first Tx after the idle period will still go out in the old modulation and rate but this seemed a simpler approach compared to adding a timer or modifying mac80211 for this.

2014-04-12sym53c8xx_2: Set DID_REQUEUE return code when aborting squeueMikulas Patocka1-0/+4
This patch fixes I/O errors with the sym53c8xx_2 driver when the disk returns QUEUE FULL status. When the controller encounters an error (including QUEUE FULL or BUSY status), it aborts all not yet submitted requests in the function sym_dequeue_from_squeue. This function aborts them with DID_SOFT_ERROR. If the disk has full tag queue, the request that caused the overflow is aborted with QUEUE FULL status (and the scsi midlayer properly retries it until it is accepted by the disk), but the sym53c8xx_2 driver aborts the following requests with DID_SOFT_ERROR --- for them, the midlayer does just a few retries and then signals the error up to sd. The result is that disk returning QUEUE FULL causes request failures. The error was reproduced on 53c895 with COMPAQ BD03685A24 disk (rebranded ST336607LC) with command queue 48 or 64 tags. The disk has 64 tags, but under some access patterns it return QUEUE FULL when there are less than 64 pending tags. The SCSI specification allows returning QUEUE FULL anytime and it is up to the host to retry.

From Florian Westphal. 4) If VLAN untagging fails, we double free the SKB in the bridging output path. From Toshiaki Makita. 5) Several call sites of sk->sk_data_ready() were referencing an SKB just added to the socket receive queue in order to calculate the second argument via skb->len. This is dangerous because the moment the skb is added to the receive queue it can be consumed in another context and freed up. It turns out also that none of the sk->sk_data_ready() implementations even care about this second argument. So just kill it off and thus fix all these use-after-free bugs as a side effect. 6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti. 7) pktgen needs to do locking properly for LLTX devices, from Daniel Borkmann. 8) xen-netfront driver initializes TX array entries in RX loop :-) From Vincenzo Maffione. 9) After refactoring, some tunnel drivers allow a tunnel to be configured on top itself.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to e1000, e1000e, igb, igbvf, ixgb, ixgbe, ixgbevf and i40evf. Mark fixes an issue with ixgbe and ixgbevf by adding a bit to indicate when workqueues have been initialized. This permits the register read error handling from attempting to use them prior to that, which also generates warnings. Checking for a detected removal after initializing the work queues allows the probe function to return an error without getting the workqueue involved. Further, if the error_detected callback is entered before the workqueues are initialized, exit without recovery since the device initialization was so truncated. Francois Romieu provides several patches to all the drivers to remove the open coded skb_cow_head. Jakub Kicinski provides a fix for igb where last_rx_timestamp should be updated only when Rx time stamp is read. Mitch provides a fix for i40evf where a recent change broke the RSS LUT programming causing it to be programmed with all 0's. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-04-12r8152: check RTL8152_UNPLUGhayeswang1-0/+48
When the device is unplugged, the driver would try to disable the device. Add checking the flag of RTL8152_UNPLUG to skip setting the device when it is unplugged. This could shorten the time of unloading the driver. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-04-12net: sun4i-emac: add promiscuous supportMarc Zyngier1-9/+21
The sun4i-emac driver is rather primitive, and doesn't support promiscuous mode. This makes usage such as bridging impossible, which is a shame on virtualization capable HW such as the Allwinner A20. The fix is fairly simple: move the RX setup code to the ndo_set_rx_mode vector, and add the required HW configuration when IFF_PROMISC is passed by the core code. This has been tested on a generic A20 box running a few virtual machines hanging off a bridge with the EMAC chip as the link to the outside world.

2014-04-11ib_srpt: Use correct ib_sg_dma primitivesMike Marciniszyn1-6/+10
The code was incorrectly using sg_dma_address() and sg_dma_len() instead of ib_sg_dma_address() and ib_sg_dma_len(). This prevents srpt from functioning with the Intel HCA and indeed will corrupt memory badly.

2014-04-11target/tcm_fc: Rename ft_{add,del}_lport to {add,del}_wwnAndy Grover1-6/+6
These functions are not adding or deleting an lport. They are adding a wwn that may match with an lport that is present on the system. Renaming ft_del_lport also means we won't have functions named both ft_del_lport and ft_lport_del any more.

2014-04-11target/tcm_fc: Rename structs and list members for clarityAndy Grover2-33/+32
Rename struct ft_lport_acl to ft_lport_wwn. "acl" is associated with something different in LIO terms. Really, ft_lport_wwn is the fabric-specific wrapper for the struct se_wwn. Rename "lacl" local variables to "ft_wwn" as well. Rename list_heads used as list members to make it clear they're nodes, not heads. Rename lport_node to ft_wwn_node.

2014-04-11target/tcm_fc: Limit to 1 TPG per wwnAndy Grover2-11/+12
tcm_fc doesn't support multiple TPGs per wwn. For proof, see ft_lport_find_tpg. Enforce this in the code. Replace ft_lport_wwn.tpg_list with a single pointer. We can't fold ft_tpg into ft_lport_wwn because they can have different lifetimes. Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
