Save & restore is an advanced power saving feature, supported only on selected devices. SR operation is almost completely transparent to the driver. Support for it is hardware and firmware dependent. Reviewed-by:

There is better to use kstrto* instead of simple_strtoul. In this case it applies a bit stricter rules for input as well. Signed-off-by:

In routine _rtl8188e_read_power_value_fromprom(), there are loops initializing index_cck_base and index_bw40_base from the PROM. As the result of a typo, the second loop is ended one element too soon. Signed-off-by:

Inside one FIFO slot queue, EDMA chipsets have the same link pointer re-read race condition as older chipsets, so the same buffer holding logic needs to be used in order to avoid use-after-free bugs. Unlike on older chips, it can be skipped for the end of the queue. Signed-off-by:

If AR_CRCErr, AR_PHYErr, AR_DecryptCRCErr or AR_MichaelErr is indicated in the rx status word, but AR_RxFrameOK is also set, the descriptor contents are typically invalid. This can show up as a warning about invalid MCS rates in a frame. Even with those checks in place, a descriptor with invalid MCS rates can still sometimes make it through to the driver (mostly on older hardware like AR91xx). Detect such errors in the last descriptor of a frame and discard the whole frame if present. Signed-off-by:

As the comment in ath_get_next_rx_buf indicates, if a descriptor with the done bit set follows one with the done bit cleared, both descriptors should be discarded, however the driver is not doing that yet. To fix this, use the rs->rs_more flag as an indicator that the following frame should be discarded. This also helps with the split buffer case: if the first part of the frame is discarded, the following parts need to be discarded as well, since they contain no valid header or usable data.

Gabor Juhos authored
The functions in the rt2x00mmio module has been moved from the rt2x00pci module. Each function uses the rt2x00pci prefix which is a bit confusing. Use the r2x000mmio prefix for each function to make it consistent with the module name. The renamed functions are used by several modules, and updating the names in all of them would result in a big patch. In order to keep the patch simple, add compatibility defines for the old function names. This allows to update the names in each module separately. After each module is updated, the defines can be removed. The patch contains no functional changes. Signed-off-by:

In brcmf_rx_frames() the call to brcmf_fweh_process_skb() could change the ifidx using information in the event data. This is only different to the BDC ifidx for IF ADD event. However, the creation of the new interface is deferred to event worker so it does not exist. After brcmf_fweh_process_skb() it is only used to set statistics. Reviewed-by:

The function brcmf_p2p_notify_action_frame_rx() the wireless_dev is needed to pass the action frame to cfg80211. The wireless_dev is held in brcmf_cfg80211_vif object. Use that instead of the ieee80211_ptr in net_device as P2P_DEVICE interface does not have a net_device associated with it. Reviewed-by:

The current driver code creates a P2P_DEVICE through a module parameter. This device has a dummy netdevice which is not how this interface type is intended. This patch add proper support for the P2P_DEVICE interface type. This requires a wpa_supplicant with such support as well. Reviewed-by:

Not locking ra_list when dequeuing packets creates race conditions. When adding a packet 'tx_pkts_queued' is modified before setting highest_priority_queue. If in-between the main loop starts, it will see a packet queued (tx_pkts_queued > 0) but will not find it, since max prio is not set yet. Depending on the scheduling, the thread trying to add the packet could complete and restore the situation. But this is not something to rely on. Another race condition exists, if a new packet, exceeding current max prio is added. If concurrently a packet is dequeued, the newly set max prio will be overwritten with the value of the dequeued packet. This can occur, because selecting a packet and modifying the max prio is not atomic. The result in an infinite loop unless, a new packet is added that has at least the priority of the hidden packet. Same applies to bss_prio_tbl. Forward iteration is no proper lock-free technique and provides no protection from calls to list_del. Although BSS are currently not added/removed dynamically, this must not be the case in the future. Hence always hold proper locks when accessing those lists. Signed-off-by:
