wireless: radiotap: fix parsing buffer overrun

2013-10-14T07:47:00Z

When parsing an invalid radiotap header, the parser can overrun the buffer that is passed in because it doesn't correctly check 1) the minimum radiotap header size 2) the space for extended bitmaps The first issue doesn't affect any in-kernel user as they all check the minimum size before calling the radiotap function. The second issue could potentially affect the kernel if an skb is passed in that consists only of the radiotap header with a lot of extended bitmaps that extend past the SKB. In that case a read-only buffer overrun by at most 4 bytes is possible. Fix this by adding the appropriate checks to the parser.

cfg80211: don't add p2p device while in RFKILL

2013-10-09T16:40:16Z

Since P2P device doesn't have a netdev associated to it, we cannot prevent the user to start it when in RFKILL. So refuse to even add it when in RFKILL. Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

cfg80211: fix sysfs registration race

2013-09-26T18:03:45Z

My locking rework/race fixes caused a regression in the registration, causing uevent notifications for wireless devices before the device is really fully registered and available in nl80211. Fix this by moving the device_add() under rtnl and move the rfkill to afterwards (it can't be under rtnl.) Reported-and-tested-by: Maxime Bizon Signed-off-by: Johannes Berg

cfg80211: fix warning when using WEXT for IBSS

2013-09-26T17:43:14Z

Fix kernel warning when using WEXT for configuring ad-hoc mode, e.g. "iwconfig wlan0 essid test channel 1" WARNING: at net/wireless/chan.c:373 cfg80211_chandef_usable+0x50/0x21c [cfg80211]() The warning is caused by an uninitialized variable center_freq1.

cfg80211: use the correct macro to check for active monitor support

2013-09-26T11:22:45Z

Use MONITOR_FLAG_ACTIVE, which is a flag mask, instead of NL80211_MNTR_FLAG_ACTIVE, which is a flag index, when checking if the hardware supports active monitoring. Cc: stable@vger.kernel.org Signed-off-by: Luciano Coelho Signed-off-by: Johannes Berg

Pull networking changes from David Miller: "Noteworthy changes this time around: 1) Multicast rejoin support for team driver, from Jiri Pirko. 2) Centralize and simplify TCP RTT measurement handling in order to reduce the impact of bad RTO seeding from SYN/ACKs. Also, when both timestamps and local RTT measurements are available prefer the later because there are broken middleware devices which scramble the timestamp. From Yuchung Cheng. 3) Add TCP_NOTSENT_LOWAT socket option to limit the amount of kernel memory consumed to queue up unsend user data. From Eric Dumazet. 4) Add a "physical port ID" abstraction for network devices, from Jiri Pirko. 5) Add a "suppress" operation to influence fib_rules lookups, from Stefan Tomanek. 6) Add a networking development FAQ, from Paul Gortmaker. 7) Extend the information provided by tcp_probe and add ipv6 support, from Daniel Borkmann. 8) Use RCU locking more extensively in openvswitch data paths, from Pravin B Shelar. 9) Add SCTP support to openvswitch, from Joe Stringer. 10) Add EF10 chip support to SFC driver, from Ben Hutchings. 11) Add new SYNPROXY netfilter target, from Patrick McHardy. 12) Compute a rate approximation for sending in TCP sockets, and use this to more intelligently coalesce TSO frames. Furthermore, add a new packet scheduler which takes advantage of this estimate when available. From Eric Dumazet. 13) Allow AF_PACKET fanouts with random selection, from Daniel Borkmann. 14) Add ipv6 support to vxlan driver, from Cong Wang" Resolved conflicts as per discussion. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1218 commits) openvswitch: Fix alignment of struct sw_flow_key. netfilter: Fix build errors with xt_socket.c tcp: Add missing braces to do_tcp_setsockopt caif: Add missing braces to multiline if in cfctrl_linkup_request bnx2x: Add missing braces in bnx2x:bnx2x_link_initialize vxlan: Fix kernel panic on device delete. net: mvneta: implement ->ndo_do_ioctl() to support PHY ioctls net: mvneta: properly disable HW PHY polling and ensure adjust_link() works icplus: Use netif_running to determine device state ethernet/arc/arc_emac: Fix huge delays in large file copies tuntap: orphan frags before trying to set tx timestamp tuntap: purge socket error queue on detach qlcnic: use standard NAPI weights ipv6:introduce function to find route for redirect bnx2x: VF RSS support - VF side bnx2x: VF RSS support - PF side vxlan: Notify drivers for listening UDP port changes net: usbnet: update addr_assign_type if appropriate driver/net: enic: update enic maintainers and driver driver/net: enic: Exposing symbols for Cisco's low latency driver ...
