The TX/RX packet counters are needed to fill in RADIUS Accounting attributes Acct-Output-Packets and Acct-Input-Packets. We already collect the needed information, but only the TX/RX bytes were previously exposed through nl80211. Allow applications to fetch the packet counters, too, to provide more complete support for accounting.

This extends the NL80211_CMD_TRIGGER_SCAN command to allow applications to specify a set of information element(s) to be added into Probe Request frames with NL80211_ATTR_IE. This provides support for the MLME-SCAN.request primitive parameter VendorSpecificInfo and can be used, e.g., to implement WPS scanning.

The AP can switch dynamically between 20/40 Mhz channel width, in which case we switch the local operating channel, but the rate control algorithm is not notified. This patch adds a new callback to indicate such changes to the RC algorithm. Currently, HT channel width change is notified, but this callback can be used to indicate any new requirements that might come up later on.

Hardware with AMPDU queues currently has broken aggregation. This patch fixes it by making all A-MPDUs go over the regular AC queues, but keeping track of the hardware queues in mac80211. As a first rough version, it actually stops the AC queue for extended periods of time, which can be removed by adding buffering internal to mac80211, but is currently not a huge problem because people rarely use multiple TIDs that are in the same AC (and iwlwifi currently doesn't operate as AP). This is a short-term fix, my current medium-term plan, which I hope to execute soon as well, but am not sure can finish before .30, looks like this: 1) rework the internal queuing layer in mac80211 that we use for fragments if the driver stopped queue in the middle of a fragmented frame to be able to queue more frames at once (rather than just a single frame with its fragments) 2) instead of stopping the entire AC queue, queue up the frames in a per-station/per-TID queue during aggregation session initiation, when the session has come up take all those frames and put them onto the queue from 1) 3) push the ampdu queue layer abstraction this patch introduces in mac80211 into the driver, and remove the virtual queue stuff from mac80211 again This plan will probably also affect ath9k in that mac80211 queues the frames instead of passing them down, even when there are no ampdu queues.

It turns out that net_alive is unnecessary, and the original problem that led to it being added was simply that the icmp code thought it was a network device and wound up being unable to handle packets while there were still packets in the network namespace. Now that icmp and tcp have been fixed to properly register themselves this problem is no longer present and we have a stronger guarantee that packets will not arrive in a network namespace then that provided by net_alive in netif_receive_skb. So remove net_alive allowing packet reception run a little faster. Additionally document the strong reason why network namespace cleanup is safe so that if something happens again someone else will have a chance of figuring it out. Signed-off-by: NEric W.

A long time ago we had bugs, primarily in TCP, where we would modify skb->truesize (for TSO queue collapsing) in ways which would corrupt the socket memory accounting. skb_truesize_check() was added in order to try and catch this error more systematically. However this debugging check has morphed into a Frankenstein of sorts and these days it does nothing other than catch false-positives. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

During peeloff/accept() sctp needs to save the parent socket state into the new socket so that any options set on the parent are inherited by the child socket.

SCTP incorrectly doubles rto ever time a Hearbeat chunk is generated. However RFC 4960 states: On an idle destination address that is allowed to heartbeat, it is recommended that a HEARTBEAT chunk is sent once per RTO of that destination address plus the protocol parameter 'HB.interval', with jittering of +/- 50% of the RTO value, and exponential backoff of the RTO if the previous HEARTBEAT is unanswered. Essentially, of if the heartbean is unacknowledged, do we double the RTO. Signed-off-by: NVlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This is a new version of my patch, now using a module parameter instead of a sysctl, so that the option is harder to find. Please note that, once the module is loaded, it is still possible to change the value of the parameter in /sys/module/sctp/parameters/, which is useful if you want to do performance comparisons without rebooting. Computation of SCTP checksums significantly affects the performance of SCTP. For example, using two dual-Opteron 246 connected using a Gbe network, it was not possible to achieve more than ~730 Mbps, compared to 941 Mbps after disabling SCTP checksums. Unfortunately, SCTP checksum offloading in NICs is not commonly available (yet). By default, checksums are still enabled, of course.

由 Andrew Morton 提交于
The problem is that in_atomic() will return false inside spinlocks if CONFIG_PREEMPT=n. This will lead to deadlockable GFP_KERNEL allocations from spinlocked regions. Secondly, if CONFIG_PREEMPT=y, this bug solves itself because networking will instead use GFP_ATOMIC from this callsite. Hence we won't get the might_sleep() debugging warnings which would have informed us of the buggy callsites. Solve both these problems by switching to in_interrupt(). Now, if someone runs a gfp_any() allocation from inside spinlock we will get the warning if CONFIG_PREEMPT=y. I reviewed all callsites and most of them were too complex for my little brain and none of them documented their interface requirements. I have no idea what this patch will do.

Giving the signal in dB isn't much more useful to userspace than giving the signal in unspecified units.

This allows drivers to request strict regulatory settings to be applied to its devices. This is desirable for devices where proper calibration and compliance can only be gauranteed for for the device's programmed regulatory domain. Regulatory domain settings will be ignored until the device's own regulatory domain is properly configured. If no regulatory domain is received only the world regulatory domain will be applied -- if OLD_REG (default to "US") is not enabled. If OLD_REG behaviour is not acceptable to drivers they must update their wiphy with a custom reuglatory prior to wiphy registration. Signed-off-by: NLuis R.

A new nl80211 command, NL80211_CMD_SET_MGMT_EXTRA_IE, can be used to add arbitrary IE data into the end of management frames. The interface allows extra IEs to be configured for each management frame subtype, but only some of them (ProbeReq, ProbeResp, Auth, (Re)AssocReq, Deauth, Disassoc) are currently accepted in mac80211 implementation.
