2010-02-03Bluetooth: Enter active mode before establishing a SCO link.Nick Pelly
When in sniff mode with a long interval time (1.28s) it can take 4+ seconds to establish a SCO link. Fix by requesting active mode before requesting SCO connection. This improves SCO setup time to ~500ms. Bluetooth headsets that use a long interval time, and exhibit the long SCO connection time include Motorola H790, HX1 and H17. They have a CSR 2.1 chipset. Verified this behavior and fix with host Bluetooth chipsets: BCM4329 and TI1271. 2009-10-13 14:17:46.183722 > HCI Event: Mode Change (0x14) plen 6 status 0x00 handle 1 mode 0x02 interval 2048 Mode: Sniff 2009-10-13 14:17:53.436285 < HCI Command: Setup Synchronous Connection (0x01|0x0028) plen 17 handle 1 voice setting 0x0060 2009-10-13 14:17:53.445593 > HCI Event: Command Status (0x0f) plen 4 Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1 2009-10-13 14:17:57.788855 > HCI Event: Synchronous Connect Complete 0x2c) plen 17 status 0x00 handle 257 bdaddr 00:1A:0E:F1:A4:7F type eSCO Air mode: CVSD Signed-off-by: Nick Pelly <npelly@google.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2010-02-03dccp: fix auto-loading of dccp(_probe)Gerrit Renker
This fixes commit (38ff3e6bb987ec583268da8eb22628293095d43b) ("dccp_probe: Fix module load dependencies between dccp and dccp_probe", from 15 Jan). It fixes the construction of the first argument of try_then_request_module(), where only valid return codes from the first argument should be returned. What we do now is assign the result of register_jprobe() to ret, without the side effect of the comparison.

2010-02-03dccp: fix bug in cache allocationGerrit Renker
This fixes a bug introduced in commit de4ef86cfce60d2250111f34f8a084e769f23b16 ("dccp: fix dccp rmmod when kernel configured to use slub", 17 Jan): the vsnprintf used sizeof(slab_name_fmt), which became truncated to 4 bytes, since slab_name_fmt is now a 4-byte pointer and no longer a 32-character array. This lead to error messages such as FATAL: Error inserting dccp: No buffer space available >> kernel: [ 1456.341501] kmem_cache_create: duplicate cache cci generated due to the truncation after the 3rd character.

Netlink code does module autoload if protocol userspace is asking for is not ready. However, module can dissapear right after it was autoloaded.

2010-02-03Bluetooth: Do not call rfcomm_session_put() for RFCOMM UA on closed socketNick Pelly
When processing a RFCOMM UA frame when the socket is closed and we were not the RFCOMM initiator would cause rfcomm_session_put() to be called twice during rfcomm_process_rx(). This would cause a kernel panic in rfcomm_session_close() then. This could be easily reproduced during disconnect with devices such as Motorola H270 that send RFCOMM UA followed quickly by L2CAP disconnect request. This trace for this looks like: 2009-09-21 17:22:37.788895 < ACL data: handle 1 flags 0x02 dlen 8 L2CAP(d): cid 0x0041 len 4 [psm 3] RFCOMM(s): DISC: cr 0 dlci 20 pf 1 ilen 0 fcs 0x7d 2009-09-21 17:22:37.906204 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 1 packets 1 2009-09-21 17:22:37.933090 > ACL data: handle 1 flags 0x02 dlen 8 L2CAP(d): cid 0x0040 len 4 [psm 3] RFCOMM(s): UA: cr 0 dlci 20 pf 1 ilen 0 fcs 0x57 2009-09-21 17:22:38.636764 < ACL data: handle 1 flags 0x02 dlen 8 L2CAP(d): cid 0x0041 len 4 [psm 3] RFCOMM(s): DISC: cr 0 dlci 0 pf 1 ilen 0 fcs 0x9c 2009-09-21 17:22:38.744125 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 1 packets 1 2009-09-21 17:22:38.763687 > ACL data: handle 1 flags 0x02 dlen 8 L2CAP(d): cid 0x0040 len 4 [psm 3] RFCOMM(s): UA: cr 0 dlci 0 pf 1 ilen 0 fcs 0xb6 2009-09-21 17:22:38.783554 > ACL data: handle 1 flags 0x02 dlen 12 L2CAP(s): Disconn req: dcid 0x0040 scid 0x0041 Avoid calling rfcomm_session_put() twice by skipping this call in rfcomm_recv_ua() if the socket is closed.

2010-02-03HID: make raw reports possible for both feature and output reportsJiri Kosina
In commit 2da31939a42 ("Bluetooth: Implement raw output support for HIDP layer"), support for Bluetooth hid_output_raw_report was added, but it pushes the data to the intr socket instead of the ctrl one. This has been fixed by 6bf8268f9a91f1 ("Bluetooth: Use the control channel for raw HID reports") Still, it is necessary to distinguish whether the report in question should be either FEATURE or OUTPUT. For this, we have to extend the generic HID API, so that hid_output_raw_report() callback provides means to specify this value so that it can be passed down to lower level hardware drivers (currently Bluetooth and USB).

This patch adds a new flag for checking the availability of a radiotap header, so that it only attempts to parse it once, reusing the tx info on the next call to ieee80211_tx(). This fixes severe issues with rekeying in AP mode. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Cc: stable@kernel.org Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-02-01mac80211: fix sta lookup for received action frames on an AP VLANFelix Fietkau
When looking for a matching interface, __ieee80211_rx_handle_packet loops over all active interfaces, looking for matching stations. Because AP VLAN interfaces are not processed as part of this loop, it needs to use sta_info_get_bss instead of sta_info_get in order to find a STA that has been moved to a VLAN. This fixes issues with aggregation setup/teardown. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Use a more compact and readable format for "agg_status" to reduce the stack frame to less than 1024 bytes. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-02-01mac80211: reduce stack usage in sta_ht_capa_read()Pavel Roskin
The maximal size of the "ht_capa" file is 430 bytes. In most cases, it's much shorter. Use a 512 byte long buffer. 1024 bytes is too much and causes a warning with CONFIG_FRAME_WARN=1024. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-02-01cfg80211: add regulatory hint disconnect supportLuis R. Rodriguez
This adds a new regulatory hint to be used when we know all devices have been disconnected and idle. This can happen when we suspend, for instance. When we disconnect we can no longer assume the same regulatory rules learned from a country IE or beacon hints are applicable so restore regulatory settings to an initial state. Since driver hints are cached on the wiphy that called the hint, those hints are not reproduced onto cfg80211 as the wiphy will respect its own wiphy->regd regardless. Signed-off-by: Luis R.

2010-02-01cfg80211: avoid flushing the global workqueue for core reg hintsLuis R. Rodriguez
When cfg80211 starts it will send a core regulatory hint. This is sent to the global workqueue but we force processing of it by flushing the global workqueue. The flushing was done since cfg80211 needs last_request to always be populated. Avoid flushing the global workqueue by processing the work required immediately instead of putting it into a linked list and processing it after the flush. Signed-off-by: Luis R.

2010-01-30Bluetooth: Use the control channel for raw HID reportsBastien Nocera
In commit 2da31939a42f7a676a0bc5155d6a0a39ed8451f2, support for Bluetooth hid_output_raw_report was added, but it pushes the data to the interrupt channel instead of the contol one. This patch makes hid_output_raw_report use the control channel instead. Using the interrupt channel was a mistake.

2010-01-28sched: add head drop fifo queueHagen Paul Pfeifer
This adds an additional queuing strategy, called pfifo_head_drop, to remove the oldest skb in the case of an overflow within the queue - the head element - instead of the last skb (tail). To remove the oldest skb in congested situations is useful for sensor network environments where newer packets reflect the superior information.

I'm not sure about rcu stuff near kmem cache destruction: * checks for non-empty hashes look bogus, they're done _before_ rcu_berrier() * unregistering netns ops is done before kmem_cache destoy (as it should), and unregistering involves rcu barriers by itself So it looks nothing should be done.
