ath_tx_setup_buffer() can fail if there is no ath_buf left, or if mapping DMA failed. In this case it frees the skb passed to it. If ath_tx_setup_buffer is called from ath_tx_form_aggr, the skb is still linked into the tid buffer list and must be dequeued before being released. Signed-off-by:

It has been found that active Rx can interfere with stopping tx DMA, which could result in at least parts of those "Failed to stop Tx DMA!" messages. Stopping rx before tx should prevent that. Signed-off-by:

mac80211 tries to verify the existence of the current AP by probing or sending a NULL frame in function ieee80211_mgd_probe_ap_send. It 1st sends a null frame to the AP, increments probe_send_count and waits for the ACK to the NULL frame for a finite duration of time. At times, it happens that by the time mac80211 gets to increment probe_send_count, the ACK for the NULL frame transmitted has already been processed. This leads to a race condition where mac80211 times out waiting for the ACK for the NULL frame causing unnecessary disconnection with the AP. Signed-off-by:

If "buf[0]" is 255 then "len" gets set to 0. The call to "crc_ccitt(0xffff, buf, len - 2);" casts the "len - 2" to a high positive number which is ugly. Signed-off-by:

This driver disables interrupt just after requesting it and enables it later, after interface is up. However currently there is a time window between request_irq() and disable_irq() where if interrupt arrives, the driver oopses because it's not yet ready to process it. This can be reproduced by inserting the module, associating and removing the module multiple times. Eliminate this race by setting IRQF_NOAUTOEN flag before request_irq().

When adding a station fails in iwl_restore_stations, the driver treats it like a successful station add and sends a link quality command, when it it shouldn't.

Shadow registers in the device are meant to allow the driver to update certain device registers without needing to wake up all components of the device.

The logic that allows to have a short TFD queue was completely wrong. We do maintain 256 Transmit Frame Descriptors, but they point to recycled buffers. We used to attach and de-attach different TFDs for the same buffer and it worked since they pointed to the same buffer. Also zero the number of BDs after unmapping a TFD. This seems not necessary since we don't reclaim the same TFD twice, but I like housekeeping.

When BT traffic load changes from its previous state, a new LQ command needs to be sent down to the firmware. This needs to be done only once per change. The state variable that keeps track of this change is last_bt_traffic_load. However, it was not being updated when the change had been handled. Not updating this variable was causing a flood of advanced BT config commands to be sent to the firmware. Fix this. Cc: stable@vger.kernel.org #2.6.38+ Signed-off-by:

Linus Torvalds authored
During early boot, when the scheduler hasn't really been fully set up, we really can't do blocking allocations because with certain (dubious) configurations the "might_resched()" calls can actually result in scheduling events. We could just make such users always use GFP_ATOMIC, but quite often the code that does the allocation isn't really aware of the fact that the scheduler isn't up yet, and forcing that kind of random knowledge on the initialization code is just annoying and not good for anybody. And we actually have a the 'gfp_allowed_mask' exactly for this reason: it's just that the kernel init sequence happens to set it to allow blocking allocations much too early. So move the 'gfp_allowed_mask' initialization from 'start_kernel()' (which is some of the earliest init code, and runs with preemption disabled for good reasons) into 'kernel_init()'. kernel_init() is run in the newly created thread that will become the 'init' process, as opposed to the early startup code that runs within the context of what will be the first idle thread. So by the time we reach 'kernel_init()', we know that the scheduler must be at least limping along, because we've already scheduled from the idle thread into the init thread. Reported-by:

There is no point having the NET dependency on the select target, as it forces all users to depend on NET to tell they support BPF_JIT. Move the config option to the bottom of the file - this could be a nice place also for future "selectable" config symbols. Fix up all users to drop the dependency on NET now that it is not required to supress warnings for non-NET builds. Reported-by:

This should make the kbuild maintainers really happy. Thanks a lot to Sam Ravnborg for his tireless efforts to get this going. 2) Convert sparc64 to nobootmem. I suspect now with sparc32 being a lot cleaner, it should be able to fall in line and modernize in this area too. 3) Make sparc32 use generic clockevents, from Tkhai Kirill. [ I fixed up the BPF rules, and tried to clean up the build rules too.

Pull networking changes from David Miller: 1) Get rid of the error prone NLA_PUT*() macros that used an embedded goto. 2) Kill off the token-ring and MCA networking drivers, from Paul Gortmaker. 3) Reduce high-order allocations made by datagram AF_UNIX sockets, from Eric Dumazet. 4) Add PTP hardware clock support to IGB and IXGBE, from Richard Cochran and Jacob Keller. 5) Allow users to query timestamping capabilities of a card via ethtool, from Richard Cochran. 6) Add loadbalance mode to the teaming driver, from Jiri Pirko. Part of this is that we can now have BPF filters not attached to sockets, and the loadbalancing function is calculated using one. 7) Francois Romieu went through the network drivers removing gratuitous uses of netdev->base_addr, perhaps some day we can remove it completely but it's used for ISA probing still. 8) Add a BPF JIT for sparc. I know, who cares, right? :-) 9) Move networking sysctl registry away from using the compatability mode interfaces in the sysctl code. From Eric W Biederman. 10) Pavel Emelyanov added a way to save and restore TCP socket state via TCP_REPAIR, TCP_REPAIR_QUEUE, and TCP_QUEUE_SEQ socket options as well as a way to forcefully bind a socket to a port via the sk->sk_reuse value SK_FORCE_REUSE. There is also a TCP_REPAIR_OPTIONS which allows to reinstante the TCP options enabled on the connection. 11) Several enhancements from Eric Dumazet that, in particular, can enhance splice performance on TCP sockets significantly. a) Reset the offset of the per-socket sendmsg page when we know we're the only use of the page in linear_to_page(). b) Add facilities such that skb->data can be backed a page rather than SLAB kmalloc'd memory. In particular devices which were receiving into linear RX buffers can now end up providing paged data. The big result is that code like splice and GRO do not have to copy any more. 12) Allow a pure sender to more gracefully handle ACK backlogs in TCP. What can happen at high rates is that the sender hasn't grown his receive buffer limits at all (he's not receiving data so really doesn't need to), but the non-data ACKs consume receive buffer space. sk_add_backlog() is too aggressive in dropping frames in this case, so relax it's requirements by using the receive buffer plus the send buffer limit as the backlog limit instead of just the former. Also from Eric Dumazet. 13) Add ipv6 support to L2TP, from Benjamin LaHaise, James Chapman, and Chris Elston. 14) Implement TCP early retransmit (RFC 5827), from Yuchung Cheng. Basically, we can start fast retransmit before hiting the dupack threshold under certain conditions. 15) New CODEL active queue management packet scheduler, from Eric Dumazet based upon initial work by Dave Taht. Basically, the big feature is that packets are dropped (or ECN bits are set) based upon how long packets live in the queue, rather than the queue length (which is what RED uses). * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1341 commits) drivers/net/stmmac: seq_file fix memory leak ipv6/exthdrs: strict Pad1 and PadN check USB: qmi_wwan: Add ZTE (Vodafone) K3520-Z USB: qmi_wwan: Add ZTE (Vodafone) K3765-Z USB: qmi_wwan: Make forced int 4 whitelist generic net/ipv4: replace simple_strtoul with kstrtoul net/ipv4/ipconfig: neaten __setup placement net: qmi_wwan: Add Vodafone/Huawei K5005 support net: cdc_ether: Add ZTE WWAN matches before generic Ethernet ipv6: use skb coalescing in reassembly ipv4: use skb coalescing in defragmentation net: introduce skb_try_coalesce() net:ipv6:fixed space issues relating to operators. net:ipv6:fixed a trailing white space issue. ipv6: disable GSO on sockets hitting dst_allfrag tg3: use netdev_alloc_frag() API net: napi_frags_skb() is static ppp: avoid false drop_monitor false positives ipv6: bool/const conversions phase2 ipx: Remove spurious NULL checking in ipx_ioctl(). ...

This teaches vfs_fstat() to use the appropriate f[get|put]_light functions, allowing it to avoid some unnecessary locking for the common case. More noticeably, it also cleans up and simplifies the "getname_flags()" function, which now relies on the architecture strncpy_from_user() doing all the user access checks properly, instead of hacking around the fact that on x86 it didn't use to do it right (see commit 92ae03f2: "x86: merge 32/64-bit versions of 'strncpy_from_user()' and speed it up"). * vfs-cleanups: VFS: make vfs_fstat() use f[get|put]_light() VFS: clean up and simplify getname_flags() x86: make word-at-a-time strncpy_from_user clear bytes at the end

This makes cp_new_stat() a bit more readable, and avoids having to memset() the whole structure just to fill in a couple of padding fields. This is another result of me looking at code generation of functions that show up high on certain kernel profiles, and just going "Oh, let's just clean that up". Architectures that don't supply the #define to fill just the padding fields will still fall back to memset(). * stat-cleanups: vfs: don't force a big memset of stat data just to clear padding fields vfs: de-crapify "cp_new_stat()" function

This series sanitizes the interface to unmap_vma(). The crazy interface annoyed me no end when I was looking at unmap_single_vma(), which we can spend quite a lot of time in (especially with loads that have a lot of small fork/exec's: shell scripts etc). Moving the nr_accounted calculations to where they belong at least clarifies things a little. I hope to come back to look at the performance of this later, but if/when I get back to it I at least don't have to see the crazy interfaces any more. * vm-cleanups: vm: remove 'nr_accounted' calculations from the unmap_vmas() interfaces vm: simplify unmap_vmas() calling convention
