2012-02-07iscsi: use IP_FREEBIND socket optionDax Kelson1-0/+8
Use IP_FREEBIND socket option so that iscsi portal configuration with explicit IP addresses can happen during boot, before network interfaces have been assigned IPs. This is especially important on systemd based Linux boxes where system boot happens asynchronously and non-trivial configuration must be done to get targetcli.service to start synchronously after the network is configured.

2012-02-07target: Fix target_submit_cmd() exception handlingNicholas Bellinger1-8/+10
This patch fixes a bug in target_submit_cmd() where the failure path for transport_generic_allocate_tasks() made a direct call to transport_send_check_condition_and_sense() and not calling the final target_put_sess_cmd() release callback. For transport_generic_allocate_tasks() failures, use the proper call to transport_generic_request_failure() to handle kref_put() along with potential internal queue full response processing. It also makes transport_lookup_cmd_lun() failures in target_submit_cmd() use transport_send_check_condition_and_sense() and target_put_sess_cmd() directly to avoid se_cmd->se_dev reference in transport_generic_request_failure() handling. Finally it drops the out_check_cond: label and use direct reference for allocate task failures, and per-se_device queue_full handling is currently not supported for transport_lookup_cmd_lun() failure descriptors due to se_device dependency.

2012-02-07target: Change target_submit_cmd() to return voidAndy Grover2-10/+4
Retval not very useful, and may even be harmful. Once submitted, fabrics should expect a sense error if anything goes wrong. All fabrics checking of this retval are useless or broken: fc checks it just to emit more debug output. ib_srpt trickles retval up, then it is ignored. qla2xxx trickles it up, which then causes a bug because the abort goto in qla_target.c thinks cmd hasn't been sent to target. Just returning nothing is best. Signed-off-by: Andy Grover <[email protected]> Signed-off-by: Nicholas Bellinger <[email protected]>
2012-02-07target: accept REQUEST_SENSE with 18bytesSebastian Andrzej Siewior1-10/+4
WindowsXP+BOT issues a MODE_SENSE request with page 0x1c which is not suppoerted by target. Target rejects that command with TCM_INVALID_CDB_FIELD, so far so good. On BOT I can't send the SENSE response back, instead I can only reply that an error occured. The next thing happens is a REQUEST_SENSE request with 18 bytes length. Since the check here is more than 18 bytes I have to NACK that request as well. This is not really required: We check for some additional room, but we never use it. The additional length is set to 0xa so the total length is 0xa + 8 = 18 which is fine with my 18 bytes.

2012-02-06drm/i915: Force explicit bpp selection for intel_dp_link_requiredKeith Packard1-15/+5
It is never correct to use intel_crtc->bpp in intel_dp_link_required, so instead pass an explicit bpp in to this function. This patch only supports 18bpp and 24bpp modes, which means that 10bpc modes will be computed incorrectly. Fixing that will require more extensive changes, and so must be addressed separately from this bugfix. intel_dp_link_required is called from intel_dp_mode_valid and intel_dp_mode_fixup. * intel_dp_mode_valid is called to list supported modes; in this case, the current crtc values cannot be relevant as the modes in question may never be selected. Thus, using intel_crtc->bpp is never right. * intel_dp_mode_fixup is called during mode setting, but it is run well before ironlake_crtc_mode_set is called to set intel_crtc->bpp, so using intel_crtc-bpp in this path can only ever get a stale value.

2012-02-06mlx4: fix DMA mapping leak when allocation failsThadeu Lima de Souza Cascardo1-1/+5
mlx4_en_prepare_rx_desc does not correctly clean up after it finds an allocation failure. It should unmap a page before calling put_page, but it only calls the later. This bug would prevent a device removal using hotplug after setting the device MTU to 9000 and opening the network interface. After the fix, we still see the allocation failure with MTU 9000, but we are able to remove the device. Signed-off-by: Thadeu Lima de Souza Cascardo <[email protected]> Signed-off-by: David S.

2012-02-06mlx4: allow device removal by fixing dma unmap sizeThadeu Lima de Souza Cascardo3-4/+6
After opening the network interface, Mellanox ConnectX device cannot be removed by hotplug because it has not properly unmapped all DMA memory. It happens that mlx4_en_activate_rx_rings overrides the variable that keeps the size of the memory mapped. This is fixed by passing to mlx4_en_destroy_rx_ring the same size that is given to mlx4_en_create_rx_ring. After applying this patch, hot unplugging the device works after opening the interface.

commit adb5066 "ath9k_hw: do not apply the 2.4 ghz ack timeout workaround to cts" reduced the hardware CTS timeout to the normal values specified by the standard, but it turns out while it doesn't need the same extra time that it needs for the ACK timeout, it does need more than the value specified in the standard, but only for 2.4 GHz.

2012-02-03ath9k: Fix kernel panic during driver initilizationMohammed Shafi Shajakhan1-4/+5
all works need to be initialized before ieee80211_register_hw to prevent mac80211 call backs such as drv_start, drv_config getting started. otherwise we would queue/cancel works before initializing them and it leads to kernel panic. this issue can be recreated with the following script in Chrome laptops with AR928X cards, with background scan running (or) Network manager is running while true do sudo modprobe -v ath9k sleep 3 sudo modprobe -r ath9k sleep 3 done EIP: [<81040a47>] __cancel_work_timer+0xb8/0xe1 SS:ESP 0068:f6be9d70 ---[ end trace 4f86d6139a9900ef ]--- Registered led device: ath9k-phy0 ieee80211 phy0: Atheros AR9280 Rev:2 mem=0xf88a0000, irq=16 Kernel panic - not syncing: Fatal exception Pid: 456, comm: wpa_supplicant Tainted: G D 3.0.13 #1 Call Trace: [<81379e21>] panic+0x53/0x14a [<81004a30>] oops_end+0x73/0x81 [<81004b53>] die+0x4c/0x55 [<81002710>] do_trap+0x7c/0x83 [<81002855>] ? do_bounds+0x58/0x58 [<810028cc>] do_invalid_op+0x77/0x81 [<81040a47>] ? __cancel_work_timer+0xb8/0xe1 [<810489ec>] ? sched_clock_cpu+0x81/0x11f [<8103f809>] ? wait_on_work+0xe2/0xf7 [<8137f807>] error_code+0x67/0x6c [<810300d8>] ? wait_consider_task+0x4ba/0x84c [<81040a47>] ? __cancel_work_timer+0xb8/0xe1 [<810380c9>] ? try_to_del_timer_sync+0x5f/0x67 [<81040a91>] cancel_work_sync+0xf/0x11 [<f88d7b7c>] ath_set_channel+0x62/0x25c [ath9k] [<f88d67d1>] ? ath9k_tx_last_beacon+0x26a/0x85c [ath9k] [<f88d8899>] ath_radio_disable+0x3f1/0x68e [ath9k] [<f90d0edb>] ieee80211_hw_config+0x111/0x116 [mac80211] [<f90dd95c>] __ieee80211_recalc_idle+0x919/0xa37 [mac80211] [<f90dda76>] __ieee80211_recalc_idle+0xa33/0xa37 [mac80211] [<812dbed8>] __dev_open+0x82/0xab Cc: <[email protected]> Cc: Gary Morain <[email protected]> Cc: Paul Stewart <[email protected]> Cc: Vasanthakumar Thiagarajan <[email protected]> Tested-by: Mohammed Shafi Shajakhan <[email protected]> Signed-off-by: Rajkumar Manoharan <[email protected]> Signed-off-by: Mohammed Shafi Shajakhan <[email protected]> Signed-off-by: John W.

2012-02-03mwifiex: handle association failure case correctlyAmitkumar Karwar1-1/+7
Currently even if association is failed "iw link" shows some information about connected BSS and "Tx timeout" error is seen in dmesg log. This patch fixes below issues in the code to handle assoc failure case correctly. 1) "status" variable in mwifiex_wait_queue_complete() is not correctly updated. Hence driver doesn't inform cfg80211 stack about association failure. 2) During association network queues are stopped but carrier is not cleared, which gives Tx timeout error in failure case Signed-off-by: Amitkumar Karwar <[email protected]> Signed-off-by: Bing Zhao <[email protected]> Signed-off-by: John W.

2012-02-03mfd: Avoid twl6040-codec PLL reconfiguration when not neededPeter Ujfalusi1-51/+74
Do not reconfigure the PLL in case it has been configured already with the requested parameters. In case of different PLL configuration do only the needed changes. This can save considerable amount of time since we can avoid the defined protocol (with delays) for the PLL configuration.
