| * xen: netfront: handle incoming GSO SKBs which are not CHECKSUM_PARTIALIan Campbell2011-01-271-8/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux network stack expects all GSO SKBs to have ip_summed == CHECKSUM_PARTIAL (which implies that the frame contains a partial checksum) and the Xen network ring protocol similarly expects an SKB which has GSO set to also have NETRX_csum_blank (which also implies a partial checksum). However there have been cases of buggy guests which mark a frame as GSO but do not set csum_blank. If we detect that we a receiving such a frame (which manifests as ip_summed != PARTIAL && skb_is_gso) then force the SKB to partial and recalculate the checksum, since we cannot rely on the peer having done so if they have not set csum_blank. Add an ethtool stat to track occurances of this event.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In drivers/net/wireless/rtlwifi/pci.c::_rtl_pci_rx_interrupt() we call dev_alloc_skb(), which may fail and return NULL, but we do not check the returned value against NULL before dereferencing the returned pointer. This may lead to a NULL pointer dereference which means we'll crash - not good. In a separate call to dev_alloc_skb(), the debug level is changed so that the failure message will always be logged.

To fix this, add those calls directly to ath_reset and drop them from callers where it makes sense.

| | | * | | RTC: Properly handle rtc_read_alarm error propagation and fix bugJohn Stultz2011-01-211-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In reviewing cases where the virtualized interfaces didn't propagate errors properly, I noticed rtc_read_alarm needed fixing. In doing so I noticed my RTC rework dropped a memset and that the behavior of rtc_read_alarm shouldn't be conditionalized on the alarm.enabled flag (as the alarm may be set, but the irqs may be disabled). So those were corrected as well.

| | | * | | RTC: Propagate error handling via rtc_timer_enqueue properlyJohn Stultz2011-01-211-21/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In cases where RTC hardware does not support alarms, the virtualized RTC interfaces did not have a way to propagate the error up to userland. This patch extends rtc_timer_enqueue so it catches errors from the hardware and returns them upwards to the virtualized interfaces. To simplify error handling, it also internalizes the management of the timer->enabled bit into rtc_timer_enqueue and rtc_timer_remove. Also makes rtc_timer_enqueue and rtc_timer_remove static.

This was found when using Xen where there is a acpi pm reported, but gives bogus values, and other code was continuing to try to use the pm timer after the initialization failed.
