| | * | | | | | | | mwifiex: avoid queue_work while work is ongoingShengzhen Li2015-03-16

This change instead sets more_task flag to ensure we run main_process superloop once again.

This means WL18XX_DEBUGFS_FWSTATS_FILE can't be used to display this field in debugfs (it would display a pointer, not the actual data). Use WL18XX_DEBUGFS_FWSTATS_FILE_ARRAY instead. This bug has been found by adding a __printf attribute to wl1271_format_buffer. gcc complained about "format '%u' expects argument of type 'unsigned int', but argument 5 has type 'u32 *'".

At first, it disables the interrupt generation, then it waits for the interrupt handler and tasklets completion, and then proceeds to the HW configuration update. But it does not consider that the interrupt handler or tasklet re-enables the interrupt generation. And we fall in a situation when ath5k assumes that interrupts are disabled, but it is not. This can lead to different consequences, such as reception of the frame, when we do not expect it. Under certain circumstances, this can lead to the following warning: WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]() invalid hw_rix: 1a [..] Call Trace: [<802656a8>] show_stack+0x48/0x70 [<802dd92c>] warn_slowpath_common+0x88/0xbc [<802dd98c>] warn_slowpath_fmt+0x2c/0x38 [<81b51be8>] ath5k_tasklet_rx+0x318/0x6ec [ath5k] [<8028ac64>] tasklet_action+0x8c/0xf0 [<80075804>] __do_softirq+0x180/0x32c [<80196ce8>] irq_exit+0x54/0x70 [<80041848>] ret_from_irq+0x0/0x4 [<80182fdc>] ioread32+0x4/0xc [<81b4c42c>] ath5k_hw_set_sleep_clock+0x2ec/0x474 [ath5k] [<81b4cf28>] ath5k_hw_reset+0x50/0xeb8 [ath5k] [<81b50900>] ath5k_reset+0xd4/0x310 [ath5k] [<81b557e8>] ath5k_config+0x4c/0x104 [ath5k] [<80d01770>] ieee80211_hw_config+0x2f4/0x35c [mac80211] [<80d09aa8>] ieee80211_scan_work+0x2e4/0x414 [mac80211] [<8022c3f4>] process_one_work+0x28c/0x400 [<802df8f8>] worker_thread+0x258/0x3c0 [<801b5710>] kthread+0xe0/0xec [<800418a8>] ret_from_kernel_thread+0x14/0x1c Fix this issue by adding a new status flag, which forbids to re-enable the interrupt generation until the HW configuration is completed.

In case of channel switch, such sequence creates a small window when a frame, which is received on the old channel is considered as a frame received on the new one. The most notable consequence of this situation occurs during the switch from 2 GHz band (CCK+OFDM) to the 5GHz band (OFDM-only). Frame received with CCK rate, e.g. beacon received at the 1mbps, causes the following warning: WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]() invalid hw_rix: 1a [..] Call Trace: [<802656a8>] show_stack+0x48/0x70 [<802dd92c>] warn_slowpath_common+0x88/0xbc [<802dd98c>] warn_slowpath_fmt+0x2c/0x38 [<81b51be8>] ath5k_tasklet_rx+0x318/0x6ec [ath5k] [<8028ac64>] tasklet_action+0x8c/0xf0 [<80075804>] __do_softirq+0x180/0x32c [<80196ce8>] irq_exit+0x54/0x70 [<80041848>] ret_from_irq+0x0/0x4 [<80182fdc>] ioread32+0x4/0xc [<81b4c42c>] ath5k_hw_set_sleep_clock+0x2ec/0x474 [ath5k] [<81b4cf28>] ath5k_hw_reset+0x50/0xeb8 [ath5k] [<81b50900>] ath5k_reset+0xd4/0x310 [ath5k] [<81b557e8>] ath5k_config+0x4c/0x104 [ath5k] [<80d01770>] ieee80211_hw_config+0x2f4/0x35c [mac80211] [<80d09aa8>] ieee80211_scan_work+0x2e4/0x414 [mac80211] [<8022c3f4>] process_one_work+0x28c/0x400 [<802df8f8>] worker_thread+0x258/0x3c0 [<801b5710>] kthread+0xe0/0xec [<800418a8>] ret_from_kernel_thread+0x14/0x1c The easiest way to reproduce this warning is to run scan with dualband NIC in noisy environments, when the channel 11 runs multiple APs. In my tests if the APs num >= 12, the warning appears in the first few seconds of scanning. In order to fix this, the Rx disable code moved to a higher level and placed before the channel pointer update. This is also makes the code a bit more symmetrical, since we disable and enable the Rx in the same function. In fact, at the pointer update time new frames should not appear, because interrupt generation at this point should already be disabled. The next patch should address this issue.
