Hi Daniel, > Queue main_work in case mwifiex_main_process() bails due to an already > processed transaction. This is particularly necessary because > mwifiex_main_process() is called from both the SDIO interrupt handler and > the workqueue. In case an interrupt occurs while the main process is > currently executed from the workqueue, the interrupt is lost, resulting in a > command timeout and consequently a card reset. > > I'm marking this for stable kernel in version 3.7+, because on our platform, > the issue appears since 601216e12c ("mwifiex: process RX packets in SDIO > IRQ thread directly") went in. > > Signed-off-by: Daniel Mack <zonque@xxxxxxxxx> > Reported-by: Sven Neumann <s.neumann@xxxxxxxxxxxx> > Reported-by: Andreas Fenkart <afenkart@xxxxxxxxx> > Cc: Bing Zhao <bzhao@xxxxxxxxxxx> > Cc: <stable@xxxxxxxxxxxxxxx> [v3.7+] Acked-by: Bing Zhao <bzhao@xxxxxxxxxxx> Thanks, Bing > --- > drivers/net/wireless/mwifiex/main.c | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/drivers/net/wireless/mwifiex/main.c > b/drivers/net/wireless/mwifiex/main.c > index ff4ed96..0700bc2 100644 > --- a/drivers/net/wireless/mwifiex/main.c > +++ b/drivers/net/wireless/mwifiex/main.c > @@ -235,6 +235,7 @@ int mwifiex_main_process(struct mwifiex_adapter > *adapter) > /* Check if already processing */ > if (adapter->mwifiex_processing) { > spin_unlock_irqrestore(&adapter->main_proc_lock, flags); > + queue_work(adapter->workqueue, &adapter->main_work); > goto exit_main_proc; > } else { > adapter->mwifiex_processing = true; > -- > 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
