Bluetooth: Fix calling request callback more than once

2013-07-29T11:28:04Z

In certain circumstances, such as an HCI driver using __hci_cmd_sync_ev with HCI_EV_CMD_COMPLETE as the expected completion event there is the chance that hci_event_packet will call hci_req_cmd_complete twice (once for the explicitly looked after event and another time in the actual handler of cmd_complete). In the case of __hci_cmd_sync_ev this introduces a race where the first call wakes up the blocking __hci_cmd_sync_ev and lets it complete. However, by the time that a second __hci_cmd_sync_ev call is already in progress the second hci_req_cmd_complete call (from the previous operation) will wake up the blocking function prematurely and cause it to fail, as witnessed by the following log: [ 639.232195] hci_rx_work: hci0 Event packet [ 639.232201] hci_req_cmd_complete: opcode 0xfc8e status 0x00 [ 639.232205] hci_sent_cmd_data: hci0 opcode 0xfc8e [ 639.232210] hci_req_sync_complete: hci0 result 0x00 [ 639.232220] hci_cmd_complete_evt: hci0 opcode 0xfc8e [ 639.232225] hci_req_cmd_complete: opcode 0xfc8e status 0x00 [ 639.232228] __hci_cmd_sync_ev: hci0 end: err 0 [ 639.232234] __hci_cmd_sync_ev: hci0 [ 639.232238] hci_req_add_ev: hci0 opcode 0xfc8e plen 250 [ 639.232242] hci_prepare_cmd: skb len 253 [ 639.232246] hci_req_run: length 1 [ 639.232250] hci_sent_cmd_data: hci0 opcode 0xfc8e [ 639.232255] hci_req_sync_complete: hci0 result 0x00 [ 639.232266] hci_cmd_work: hci0 cmd_cnt 1 cmd queued 1 [ 639.232271] __hci_cmd_sync_ev: hci0 end: err 0 [ 639.232276] Bluetooth: hci0 sending Intel patch command (0xfc8e) failed (-61) Signed-off-by: Johan Hedberg Acked-by: Marcel Holtmann Signed-off-by: Gustavo Padovan

Bluetooth: Fix HCI init for BlueFRITZ! devices

2013-07-29T11:12:27Z

None of the BlueFRITZ! devices with manufacurer ID 31 (AVM Berlin) support HCI_Read_Local_Supported_Commands. It is safe to use the manufacturer ID (instead of e.g. a USB ID specific quirk) because the company never created any newer controllers. < HCI Command: Read Local Supported Comm..

Bluetooth: Fix race between hci_register_dev() and hci_dev_open()

2013-07-25T18:52:36Z

If hci_dev_open() is called after hci_register_dev() added the device to the hci_dev_list but before the workqueue are created we could run into a NULL pointer dereference (see below). This bug is very unlikely to happen, systems using bluetoothd to manage their bluetooth devices will never see this happen.

Bluetooth: Fix invalid length check in l2cap_information_rsp()

2013-07-25T18:52:30Z

The length check is invalid since the length varies with type of info response. This was introduced by the commit cb3b3152b2f5939d67005cff841a1ca748b19888 Because of this, l2cap info rsp is not handled and command reject is sent. > ACL data: handle 11 flags 0x02 dlen 16 L2CAP(s): Info rsp: type 2 result 0 Extended feature mask 0x00b8 Enhanced Retransmission mode Streaming mode FCS Option Fixed Channels < ACL data: handle 11 flags 0x00 dlen 10 L2CAP(s): Command rej: reason 0 Command not understood Cc: stable@vger.kernel.org Signed-off-by: Jaganath Kanakkassery Signed-off-by: Chan-Yeol Park Acked-by: Johan Hedberg Signed-off-by: Gustavo Padovan

Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...

drivers: avoid format strings in names passed to alloc_workqueue()

2013-07-03T23:07:41Z

For the workqueue creation interfaces that do not expect format strings, make sure they cannot accidently be parsed that way. Additionally, clean up calls made with a single parameter that would be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents.
