commit 86271e460a66003dc1f4cbfd845adafb790b7587 introduced a regression that caused mac80211 queues in stopped state. ath_drain_all_txq is called in driver flush which would reset the stopped flag and the mac80211 queues were never started after that. iperf traffic is completely stalled due to this issue. Restart the mac80211 queues in driver flush only if the txqs were drained. Signed-off-by: Senthil Balasubramanian <senthilkumar@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-03-23ath9k: Fix kernel panic caused by invalid rate index access.Senthil Balasubramanian
With the recent tx status optimization in mac80211, we bail out as and and when invalid rate index is found. So the behavior of resetting rate idx to -1 and count to 0 has changed for the rate indexes that were not part of the driver's retry series. This has resulted in ath9k using incorrect rate table index which caused the system to panic. Ideally ath9k need to loop only for the indexes that were part of the retry series and so simply use hw->max_rates as the loop counter. Pasted the stack trace of the panic issue for reference.

2011-03-22zlib: slim down zlib_deflate() workspace when possibleJim Keniston
Instead of always creating a huge (268K) deflate_workspace with the maximum compression parameters (windowBits=15, memLevel=8), allow the caller to obtain a smaller workspace by specifying smaller parameter values. For example, when capturing oops and panic reports to a medium with limited capacity, such as NVRAM, compression may be the only way to capture the whole report. In this case, a small workspace (24K works fine) is a win, whether you allocate the workspace when you need it (i.e., during an oops or panic) or at boot time. I've verified that this patch works with all accepted values of windowBits (positive and negative), memLevel, and compression level.

2011-03-22IB: Increase DMA max_segment_size on Mellanox hardwareDavid Dillow
By default, each device is assumed to be able only handle 64 KB chunks during DMA. By giving the segment size a larger value, the block layer will coalesce more S/G entries together for SRP, allowing larger requests with the same sg_tablesize setting. The block layer is the only direct user of it, though a few IOMMU drivers reference it as well for their *_map_sg coalescing code. pci-gart_64 on x86, and a smattering on on sparc, powerpc, and ia64. Since other IB protocols could potentially see larger segments with this, let's check those: - iSER is fine, because you limit your maximum request size to 512 KB, so we'll never overrun the page vector in struct iser_page_vec (128 entries currently). It is independent of the DMA segment size, and handles multi-page segments already. - IPoIB is fine, as it maps each page individually, and doesn't use ib_dma_map_sg(). - RDS appears to do the right thing and has no dependencies on DMA segment size, but I don't claim to have done a complete audit. - NFSoRDMA and 9p are OK -- they do not use ib_dma_map_sg(), so they doesn't care about the coalescing. - Lustre's ko2iblnd does not care about coalescing -- it properly walks the returned sg list. This patch ups the value on Mellanox hardware to 1 GB, which matches reported firmware limits on mlx4.

2011-03-21veth: Fix the byte countersEric W. Biederman
Commit 44540960 "veth: move loopback logic to common location" introduced a bug in the packet counters. I don't understand why that happened as it is not explained in the comments and the mut check in dev_forward_skb retains the assumption that skb->len is the total length of the packet. I just measured this emperically by setting up a veth pair between two noop network namespaces setting and attempting a telnet connection between the two. I saw three packets in each direction and the byte counters were exactly 14*3 = 42 bytes high in each direction. I got the actual packet lengths with tcpdump. So remove the extra ETH_HLEN from the veth byte count totals. Signed-off-by: Eric W. Biederman <ebiederm@aristanetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-21macvlan: Fix use after free of struct macvlan_port.Eric W. Biederman
When the macvlan driver was extended to call unregisgter_netdevice_queue in 23289a37e2b127dfc4de1313fba15bb4c9f0cd5b, a use after free of struct macvlan_port was introduced. The code in dellink relied on unregister_netdevice actually unregistering the net device so it would be safe to free macvlan_port. Since unregister_netdevice_queue can just queue up the unregister instead of performing the unregiser immediately we free the macvlan_port too soon and then the code in macvlan_stop removes the macaddress for the set of macaddress to listen for and uses memory that has already been freed. To fix this add a reference count to track when it is safe to free the macvlan_port and move the call of macvlan_port_destroy into macvlan_uninit which is guaranteed to be called after the final macvlan_port_close.

2011-03-21can: c_can: Do basic c_can configuration _before_ enabling the interruptsJan Altenberg
I ran into some trouble while testing the SocketCAN driver for the BOSCH C_CAN controller. The interface is not correctly initialized, if I put some CAN traffic on the line, _while_ the interface is being started (which means: the interface doesn't come up correcty, if there's some RX traffic while doing 'ifconfig can0 up'). The current implementation enables the controller interrupts _before_ doing the basic c_can configuration. I think, this should be done the other way round. The patch below fixes things for me.

2011-03-21ath9k: Fix kernel panic in AR2427Mohammed Shafi Shajakhan
Kernel panic occurs just after AR2427 establishes connection with AP. Unless aggregation is enabled we don't initialize the TID structure. Thus accesing the elements of the TID structure when aggregation is disabled, leads to NULL pointer dereferencing.
