git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless John W. Linville says: ==================== Here is another handful of late-breaking fixes intended for the 3.8 stream... Hopefully the will still make it! :-) There are three mac80211 fixes pulled from Johannes: "Here are three fixes still for the 3.8 stream, the fix from Cong Ding for the bad sizeof (Stephen Hemminger had pointed it out before but I'd promptly forgotten), a mac80211 managed-mode channel context usage fix where a downgrade would never stop until reaching non-HT and a bug in the channel determination that could cause invalid channels like HT40+ on channel 11 to be used." Also included is a mwl8k fix that avoids an oops when using mwl8k devices that only support the 5 GHz band. Please let me know if there are problems! ==================== Signed-off-by: David S.

2013-02-12ixgbe: Only set gso_type to SKB_GSO_TCPV4 as RSC does not support IPv6Alexander Duyck
The original fix that was applied for setting gso_type required more change than necessary because it was assumed ixgbe does RSC on IPv6 frames and this is not correct. RSC is only supported with IPv4/TCP frames only. As such we can simplify the fix and avoid the unnecessary move of eth_type_trans. The previous patch "ixgbe: fix gso type" and this patch reduce the entire fix to one line that sets gso_type to TCPV4 if the frame is RSC.

2013-02-12net: fix infinite loop in __skb_recv_datagram()Eric Dumazet
Tommi was fuzzing with trinity and reported the following problem : commit 3f518bf745 (datagram: Add offset argument to __skb_recv_datagram) missed that a raw socket receive queue can contain skbs with no payload. We can loop in __skb_recv_datagram() with MSG_PEEK mode, because wait_for_packet() is not prepared to skip these skbs.

2013-02-11netpoll: Fix __netpoll_rcu_free so that it can hold the rtnl lockNeil Horman
__netpoll_rcu_free is used to free netpoll structures when the rtnl_lock is already held. The mechanism is used to asynchronously call __netpoll_cleanup outside of the holding of the rtnl_lock, so as to avoid deadlock. Unfortunately, __netpoll_cleanup modifies pointers (dev->np), which means the rtnl_lock must be held while calling it. Further, it cannot be held, because rcu callbacks may be issued in softirq contexts, which cannot sleep. Fix this by converting the rcu callback to a work queue that is guaranteed to get scheduled in process context, so that we can hold the rtnl properly while calling __netpoll_cleanup Tested successfully by myself.

2013-02-11mwl8k: fix band for supported channelsJonas Gorski
The band field for the supported channels were left unpopulated, making them default to 0 == IEEE80211_BAND_2GHZ, even for the 5GHz channels. This resulted in null pointer accesses if anything tries to access wiphy->bands[channel->band] of a 5GHz channel on 5GHz only cards, since wiphy->bands[2GHZ] is NULL for them (e.g. cfg80211_chandef_usable does).

David Ward says: ==================== The Linux kernel currently implements the GARP VLAN Registration Protocol (GVRP) from IEEE 802.1Q-1998 (applicant-only participant). When the GVRP flag is set for a VLAN interface on a Linux host, the host advertises its membership in the VLAN to the attached bridge/ switch, so that it is not necessary to manually configure the bridge/ switch port to participate in the VLAN. GVRP has been superseded by the Multiple VLAN Registration Protocol (MVRP) in IEEE 802.1Q-2011, which addresses scalability concerns about the earlier protocol. The following patches add support for MVRP to the Linux kernel and iproute2 utility. They are based largely off of the existing implementation of GVRP, but have been modified for the new PDU structure and state machine. This implementation was tested with two Juniper EX4200 switches. ==================== Signed-off-by: David Ward <david.ward@ll.mit.edu> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

This didn't use to be the case: with intel cards on 3.2 and older kernels, with qlogic - on 3.4 and older kernels, so it's a regression if not a recent one.

2013-02-10bnx2x: set gso_typeMichael S. Tsirkin
In LRO mode, bnx2x set gso_size but not gso type. This leads to crashes in macvtap. Commit cbf1de72324a8105ddcc3d9ce9acbc613faea17e queued for 3.9 includes a more complete fix. This is a minimal patch to avoid the crash, for 3.8. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Dmitry Kravkov <dmitry@broadcom.com> Signed-off-by: David S.

2013-02-10Merge branch 'vsock'David S. Miller
Andy King says: ==================== In an effort to improve the out-of-the-box experience with Linux kernels for VMware users, VMware is working on readying the VM Sockets (VSOCK, formerly VMCI Sockets) (vsock) kernel module for inclusion in the Linux kernel. The purpose of this post is to acquire feedback on the vsock kernel module. Unlike previous submissions, where the new socket family was entirely reliant on VMware's VMCI PCI device (and thus VMware's hypervisor), VM Sockets is now completely[1] separated out into two parts, each in its own module: o Core socket code, which is transport-neutral and invokes transport callbacks to communicate with the hypervisor. This is vsock.ko. o A VMCI transport, which communicates over VMCI with the VMware hypervisor. This is vmw_vsock_vmci_transport.ko, and it registers with the core module as a transport. This should provide a path to introducing additional transports, for example virtio, with the ultimate goal being to make this new socket family hypervisor-neutral. [1] If Gerd tries it and determines this to be false (still), I'll ship him a keg of beer. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2013-02-10VSOCK: Introduce VM SocketsAndy King
VM Sockets allows communication between virtual machines and the hypervisor. User level applications both in a virtual machine and on the host can use the VM Sockets API, which facilitates fast and efficient communication between guest virtual machines and their host. A socket address family, designed to be compatible with UDP and TCP at the interface level, is provided. Today, VM Sockets is used by various VMware Tools components inside the guest for zero-config, network-less access to VMware host services. In addition to this, VMware's users are using VM Sockets for various applications, where network access of the virtual machine is restricted or non-existent. Examples of this are VMs communicating with device proxies for proprietary hardware running as host applications and automated testing of applications running within virtual machines. The VMware VM Sockets are similar to other socket types, like Berkeley UNIX socket interface. The VM Sockets module supports both connection-oriented stream sockets like TCP, and connectionless datagram sockets like UDP. The VM Sockets protocol family is defined as "AF_VSOCK" and the socket operations split for SOCK_DGRAM and SOCK_STREAM. For additional information about the use of VM Sockets, please refer to the VM Sockets Programming Guide available at: https://www.vmware.com/support/developer/vmci-sdk/ Signed-off-by: George Zhang <georgezhang@vmware.com> Signed-off-by: Dmitry Torokhov <dtor@vmware.com> Signed-off-by: Andy king <acking@vmware.com> Signed-off-by: David S.

2013-02-08net: sctp: sctp_auth_make_key_vector: use sctp_auth_create_keyDaniel Borkmann
In sctp_auth_make_key_vector, we allocate a temporary sctp_auth_bytes structure with kmalloc instead of the sctp_auth_create_key allocator. Change this to sctp_auth_create_key as it is the case everywhere else, so that we also can properly free it via sctp_auth_key_put. This makes it easier for future code changes in the structure and allocator itself, since a single API is consistently used for this purpose. Also, by using sctp_auth_create_key we're doing sanity checks over the arguments.
