This patch fixes the tx_timeout() to properly handle the clean up of the tx ring. It also sets the tx put pointer back to the correct position to be in sync with HW. Signed-off-by:

Currently, the VLAN event handler does not adjust the VLAN device's carrier state when the real device or the VLAN device is set administratively up or down. The following patch adds a transfer of operating state from the real device to the VLAN device when the real device is administratively set up or down, and sets the carrier state up or down during init, open and close of the VLAN device. This permits observers above the VLAN device that care about the carrier state (bonding's link monitor, for example) to receive updates for administrative changes by more closely mimicing the behavior of real devices.

Related-to: commit 325fb5b4 The compat path suffers from a similar problem. It only uses a __be32 when all of the recent code uses, and expects, an nf_inet_addr everywhere. As a result, addresses stored by xt_recents were filled with whatever other stuff was on the stack following the be32. Signed-off-by:

Commit d0dba725 (netfilter: ctnetlink: add callbacks to the per-proto nlattrs) changed the protocol registration function to abort if the to-be registered protocol doesn't provide a new callback function. The DCCP and UDP-Lite IPv6 protocols were missed in this conversion, add the required callback pointer. Reported-and-tested-by:

The NetLabel address selector mechanism has a problem where it can get mistakenly remove the wrong selector when similar addresses are used. The problem is caused when multiple addresses are configured that have different netmasks but the same address, e.g. 127.0.0.0/8 and 127.0.0.0/24. This patch fixes the problem. Reported-by:

While ifconfig eth0 up kernel calls open() of 8139 driver(8139too.c). In rtl8139_hw_start() of rtl8139_open(), 8139 driver enable RX before setting up the DMA buffer address. In this interval where RX was enabled and DMA buffer address is not yet set up, any incoming broadcast packet would be send to a strange physical address: 0x003e8800 which is the default value of DMA buffer address. Unfortunately, this address is used by Linux kernel. So kernel panics. This patch fix it by setting up DMA buffer address before RX enabled and everything is fine even under broadcast packets attack.

AF_IUCV runs into a race when queuing incoming iucv messages and receiving the resulting backlog. If the Linux system is under pressure (high load or steal time), the message queue grows up, but messages are not received and queued onto the backlog queue. In that case, applications do not receive any data with recvmsg() even if AF_IUCV puts incoming messages onto the message queue. The race can be avoided if the message queue spinlock in the message_pending callback is spreaded across the entire callback function. Signed-off-by:

If iucv_sock_recvmsg() is called with MSG_PEEK flag set, the skb is enqueued twice. If the socket is then closed, the pointer to the skb is freed twice. Remove the skb_queue_head() call for MSG_PEEK, because the skb_recv_datagram() function already handles MSG_PEEK (does not dequeue the skb). Signed-off-by:

A few issues wrt DMA were uncovered when using the driver with swiotlb. - driver should not use memory after it has been mapped - iwl3945's RX queue management cannot use all of iwlagn because the size of the RX buffer is different. Revert back to using iwl3945 specific routines that map/unmap memory. - no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single, we can just call pci_unmap_single initially - only map the memory area that will be used by device. this is especially relevant to the mapping of iwl_cmd. we should not map the entire structure because the meta data at the beginning of structure contains the address to be used later for unmapping. If the address to be used for unmapping is stored in mapped data it creates a problem. - ensure that _if_ memory needs to be modified after it is mapped that we call _sync_single_for_cpu first, and then release it back to device with _sync_single_for_device - we mapped the wrong length of data for host commands, with mapped length differing with length provided to device, fix that.

When debugging TX issues it is helpful to know the seq nr of the frame being transmitted. The seq nr is printed as part of ucode's log informing us which frame is being processed. Having this information printed in driver log makes it easy to match activities between driver and firmware. Also make possible to print TX flags directly. These are already printed as part of entire TX command, but having it printed directly in cpu format makes it easier to look at. Signed-off-by:

This patch fixes a build warning in mwl8.c. (Marvell TOPDOG wireless driver) The warning it fixes is: "large integer implicitly truncated to unsigned type." The rx_ctrl member of the mwl8k_rx_desc struct is 8 bit (__u8 ), whereas trying to assign it a 32 bit value (which is returned from cpu_to_le32()) causes the compiler to issue a truncation warning.

It is expected that config interface will always succeed as mac80211 will only request what driver supports. The exception here is when a device has rfkill enabled. At this time the rfkill state is unknown to mac80211 and config interface can fail. When this happens we deal with this error instead of printing a WARN. Signed-off-by:

Currently beacon loss detection triggers after a scan. A probe request is sent and a message like this is printed to the log: wlan0: beacon loss from AP 00:12:17:e7:98:de - sending probe request But in fact there is no beacon loss, the beacons are just not received because of the ongoing scan. Fix it by updating last_beacon after the scan has finished. Reported-by:
