* | genetlink: introduce pre_doit/post_doit hooksJohannes Berg2010-10-051-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each family may have some amount of boilerplate locking code that applies to most, or even all, commands. This allows a family to handle such things in a more generic way, by allowing it to a) include private flags in each operation b) specify a pre_doit hook that is called, before an operation's doit() callback and may return an error directly, c) specify a post_doit hook that can undo locking or similar things done by pre_doit, and finally d) include two private pointers in each info struct passed between all these operations including doit(). (It's two because I'll need two in nl80211 -- can be extended.) Signed-off-by: Johannes Berg <johannes.berg@intel.com> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: John W.

* | mac80211: distinct between max rates and the number of rates the hw can reportHelmut Schaa2010-10-051-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers cannot handle multiple retry rates specified by the rc algorithm but instead use their own retry table (for example rt2800). However, if such a device registers itself with a max_rates value of 1 the rc algorithm cannot make use of the extended information the device can provide about retried rates. On the other hand, if a device registers itself with a max_rates value > 1 the rc algorithm assumes that the device can handle multi rate retries. Fix this issue by introducing another hw parameter max_report_rates that can be set to a different value then max_rates to indicate if a device is capable of reporting more rates then specified in max_rates.

* mac80211: move packet flags into packetJohannes Berg2010-09-271-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 8c0c709eea5cbab97fb464cd68b06f24acc58ee1 Author: Johannes Berg <johannes@sipsolutions.net> Date: Wed Nov 25 17:46:15 2009 +0100 mac80211: move cmntr flag out of rx flags moved the CMNTR flag into the skb RX flags for some aggregation cleanups, but this was wrong since the optimisation this flag tried to make requires that it is kept across the processing of multiple interfaces -- which isn't true for flags in the skb. The patch not only broke the optimisation, it also introduced a bug: under some (common!) circumstances the flag will be set on an already freed skb! However, investigating this in more detail, I found that most of the flags that we set should be per packet, _except_ for this one, due to a-MPDU processing. Additionally, the flags used for processing (currently just this one) need to be reset before processing a new packet. Since we haven't actually seen bugs reported as a result of the wrong flags handling (which is not too surprising -- the only real bug case I can come up with is an a-MSDU contained in an a-MPDU), I'll make a different fix for rc.

* mac80211/ath9k: Support AMPDU with multiple VIFs.Ben Greear2010-09-271-11/+14
| | | | | | | | | | | | | | | | The old ieee80211_find_sta_by_hw method didn't properly find VIFS when there was more than one per AP. This caused AMPDU logic in ath9k to get the wrong VIF when trying to account for transmitted SKBs. This patch changes ieee80211_find_sta_by_hw to take a localaddr argument to distinguish between VIFs with the same AP but different local addresses. The method name is changed to ieee80211_find_sta_by_ifaddr. Signed-off-by: Ben Greear <greearb@candelatech.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

Because ieee80211_handle_filtered_frame feeds skbs back into the tx path, they have to be stripped of some tx flags so they won't confuse the stack, driver or device.

| * Bluetooth: Use 3-DH5 payload size for default ERTM max PDU sizeMat Martineau2010-08-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous value of 672 for L2CAP_DEFAULT_MAX_PDU_SIZE is based on the default L2CAP MTU. That default MTU is calculated from the size of two DH5 packets, minus ACL and L2CAP b-frame header overhead. ERTM is used with newer basebands that typically support larger 3-DH5 packets, and i-frames and s-frames have more header overhead. With clean RF conditions, basebands will typically attempt to use 1021-byte 3-DH5 packets for maximum throughput. Adjusting for 2 bytes of ACL headers plus 10 bytes of worst-case L2CAP headers yields 1009 bytes of payload. This PDU size imposes less overhead for header bytes and gives the baseband the option to choose 3-DH5 packets, but is small enough for ERTM traffic to interleave well with other L2CAP or SCO data. 672-byte payloads do not allow the most efficient over-the-air packet choice, and cannot achieve maximum throughput over BR/EDR.
