2018-06-27ipw2x00: track time using boottimeArnd Bergmann
The ipw2x00 driver family uses get_seconds() to read the current time for various purposes. This function is deprecated because of the 32-bit time_t overflow, and it can cause unexpected behavior when the time changes due to settimeofday() calls or leap second updates. In many cases, we want to use monotonic time instead, however ipw2x00 explicitly tracks the time spent in suspend, so this changes the driver over to use ktime_get_boottime_seconds(), which is slightly slower, but not used in a fastpath here.

2018-06-27zd1211rw: stop using deprecated get_seconds()Arnd Bergmann
The get_seconds() function is deprecated because of the y2038 overflow. In zd1211rw we don't even care about the absolute value, so this is not a problem, but it's equally trivial to change to the non-deprecated ktime_get_seconds().

2018-06-27wireless-drivers: use BIT_ULL for NL80211_STA_INFO_ attribute typesOmer Efrat
The BIT macro uses unsigned long which some architectures handle as 32 bit and therefore might cause macro's shift to overflow when used on a value equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards). Since 'filled' member in station_info changed to u64, BIT_ULL macro should be used with all NL80211_STA_INFO_* attribute types instead of BIT to prevent future possible bugs when one will use BIT macro for higher attributes by mistake. This commit cleans up all usages of BIT macro with the above field in wireless-drivers by changing it to BIT_ULL instead. In addition, there are some places which don't use BIT nor BIT_ULL macros so align those as well. Signed-off-by: Omer Efrat <omer.efrat@tandemg.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-06-27rndis_wlan: potential buffer overflow in rndis_wlan_auth_indication()Dan Carpenter
This is a static checker fix, not something I have tested. The issue is that on the second iteration through the loop, we jump forward by le32_to_cpu(auth_req->length) bytes. The problem is that if the length is more than "buflen" then we end up with a negative "buflen". A negative buflen is type promoted to a high positive value and the loop continues but it's accessing beyond the end of the buffer. I believe the "auth_req->length" comes from the firmware and if the firmware is malicious or buggy, you're already toasted so the impact of this bug is probably not very severe.

2018-06-27wlcore: Enable runtime PM autosuspend supportTony Lindgren
With runtime PM tested working for wlcore with no autosuspend, we can now enable autosuspend to cut down on enable/disable for interrupts. Basically we just replace pm_runtime_put() with the autosuspend variants. Let's use autosuspend delay of 50ms that MMC drivers typically use.

2018-06-27wlcore: Make sure firmware is initialized in wl1271_op_add_interface()Tony Lindgren
We have wl12xx_boot() call wl12xx_enable_interrupts() and if we have wl1271_op_add_interface() call pm_runtime_get_sync() before the interrupts are enabled. And then we get the following error during boot: wlcore: ERROR ELP wakeup timeout! Let's fix this by first checking if we need to boot the firmware. And only after that call pm_runtime_get_sync() when interrupts are enabled. And only after that do the check for wl12xx_need_fw_change().

2018-06-27wlcore: Use generic runtime pm calls for wowlan elp configurationEyal Reizer
With runtime PM enabled, we can now use calls to pm_runtime_force_suspend and pm_runtime_force_resume for enabling elp during suspend when wowlan is enabled and waking the chip from elp on resume. Remove the custom API that was used to ensure that the command that is used to allow ELP during suspend is completed before the system suspend.

2018-06-27wlcore: Fix timout errors after recoveryTony Lindgren
After enabling runtime PM, if we force hardware reset multiple times with: # echo 1 > /sys/kernel/debug/ieee80211/phy0/wlcore/start_recovery We will after few tries get the following error: wlcore: ERROR timeout waiting for the hardware to complete initialization And then wlcore is unable to reconnect until after the wlcore related modules are reloaded. Let's fix this by moving pm_runtime_put() earlier before we restart the hardware. And let's use the sync version to make sure we're done before we restart. Note that we still will get -EBUSY warning from wl12xx_sdio_set_power() but let's fix that separately once we know exactly why we get the warning.

2018-06-27wlcore: Fix misplaced PM call for scan_complete_work()Tony Lindgren
With runtime PM enabled, we now need to have wlcore enabled longer until after we're done calling wlcore_cmd_regdomain_config_locked(): scan_complete_work() wlcore_cmd_regdomain_config_locked() wlcore_cmd_send_failsafe() wl12xx_sdio_raw_read() Note that this is not needed before runtime PM support as the custom PM code had it's own timer. We have not yet enabled runtime PM autosuspend for wlcore and this is why this issue now shows up. Let's fix the issues first before we enable runtime PM autosuspend.

2018-06-27wlcore: Add support for runtime PMTony Lindgren
We can update wlcore to use PM runtime by adding functions for wlcore_runtime_suspend() and wlcore_runtime_resume() and replacing calls to wl1271_ps_elp_wakeup() and wl1271_ps_elp_sleep() with calls to pm_runtime_get_sync() and pm_runtime_put(). Note that the new wlcore_runtime_suspend() and wlcore_runtime_resume() functions are based on simplified versions of wl1271_ps_elp_sleep() and wl1271_ps_elp_wakeup(). We don't want to use the old functions as we can now take advantage of the runtime PM usage count. And we don't need the old elp_work at all. And we can also remove WL1271_FLAG_ELP_REQUESTED that is no longer needed. Pretty much the only place where we are not just converting the existing functions is wl1271_op_suspend() where we add pm_runtime_put_noidle() to keep the calls paired. As the next step is to implement runtime PM autosuspend, let's not add wrapper functions for the generic runtime PM calls. We would be getting rid of any wrapper functions anyways. After autoidle we should be able to start using Linux generic wakeirqs for the padconf interrupt. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-06-27wlcore: Make sure PM calls are pairedTony Lindgren
The call to wl1271_ps_elp_wakeup() in wl12xx_queue_recovery_work() is unpaired. Let's remove it and add paired calls to wl1271_recovery_work() instead in preparation for changing things to use runtime PM.

2018-06-27wlcore: Add missing PM call for wlcore_cmd_wait_for_event_or_timeout()Tony Lindgren
Otherwise we can get: WARNING: CPU: 0 PID: 55 at drivers/net/wireless/ti/wlcore/io.h:84 I've only seen this few times with the runtime PM patches enabled so this one is probably not needed before that. This seems to work currently based on the current PM implementation timer. Let's apply this separately though in case others are hitting this issue.

This then leads to discrepancies in reference counting when the VLAN is removed. spectrum.c warns about the problem when the module is removed: [13578.493090] WARNING: CPU: 0 PID: 2454 at drivers/net/ethernet/mellanox/mlxsw/spectrum.c:2973 mlxsw_sp_port_remove+0xfd/0x110 [mlxsw_spectrum] [...] [13578.627106] Call Trace: [13578.629617] mlxsw_sp_fini+0x2a/0xe0 [mlxsw_spectrum] [13578.634748] mlxsw_core_bus_device_unregister+0x3e/0x130 [mlxsw_core] [13578.641290] mlxsw_pci_remove+0x13/0x40 [mlxsw_pci] [13578.646238] pci_device_remove+0x31/0xb0 [13578.650244] device_release_driver_internal+0x14f/0x220 [13578.655562] driver_detach+0x32/0x70 [13578.659183] bus_remove_driver+0x47/0xa0 [13578.663134] pci_unregister_driver+0x1e/0x80 [13578.667486] mlxsw_sp_module_exit+0xc/0x3fa [mlxsw_spectrum] [13578.673207] __x64_sys_delete_module+0x13b/0x1e0 [13578.677888] ? exit_to_usermode_loop+0x78/0x80 [13578.682374] do_syscall_64+0x39/0xe0 [13578.685976] entry_SYSCALL_64_after_hwframe+0x44/0xa9 Fix by putting the port_vlan when mlxsw_sp_port_vlan_bridge_join() determines it's a flag-only change.

2018-06-15stmmac: added support for 802.1ad vlan strippingElad Nachman
stmmac reception handler calls stmmac_rx_vlan() to strip the vlan before calling napi_gro_receive(). The function assumes VLAN tagged frames are always tagged with 802.1Q protocol, and assigns ETH_P_8021Q to the skb by hard-coding the parameter on call to __vlan_hwaccel_put_tag() . This causes packets not to be passed to the VLAN slave if it was created with 802.1AD protocol (ip link add link eth0 eth0.100 type vlan proto 802.1ad id 100). This fix passes the protocol from the VLAN header into __vlan_hwaccel_put_tag() instead of using the hard-coded value of ETH_P_8021Q. NETIF_F_HW_VLAN_STAG_RX check was added and the strip action is now dependent on the correct combination of features and the detected vlan tag. NETIF_F_HW_VLAN_STAG_RX feature was added to be in line with the driver actual abilities.

2018-06-15nvme-fabrics: fix and refine state checks in __nvmf_check_readyChristoph Hellwig
- make sure we only allow internally generates commands in any non-live state - only allow connect commands on non-live queues when actually in the new or connecting states - treat all other non-live, non-dead states the same as a default cach-all This fixes a regression where we could not shutdown a controller orderly as we didn't allow the internal generated Property Set command, and also ensures we don't accidentally let a Connect command through in the wrong state.

Move the is_connected check to the fibre channel transport, as it has no meaning for other transports. To facilitate this split out a new nvmf_fail_nonready_command helper that is called by the transport when it is asked to handle a command on a queue that is not ready. Also avoid a function call for the queue live fast path by inlining the check. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: James Smart <james.smart@broadcom.com>
