The auto negotiation logic was geared to being the initiator of the auto negotiation. This presented problems when auto negotiation was initiated by the remote end. Change the auto negotiation logic to make use of the auto negotiation event interrupt thus allowing the auto negotiation state machine to function properly in either scenario. This also removes the polling during auto-negotiation. Signed-off-by:

Since the Tx ring cleanup can run at the same time that data is being transmitted, a spin lock was used to protect the ring. This patch eliminates the need for Tx spinlocks by updating the current ring position only after all ownership bits for data being transmitted have been set. This will insure that ring operations in the Tx cleanup path do not interfere with the ring operations in the Tx transmit path. Signed-off-by:

When performing a device restart, like during an MTU change, sometimes the device queues still have data and get hung up trying to flush resulting in the device becoming unresponsive until brought down and back up. To prevent this, always perform a device reset during a restart. Signed-off-by:

When we put our declared work task in the global workqueue with schedule_delayed_work(), its delay parameter is always zero. Therefore, we should define a regular work in rhashtable structure instead of a delayed work. By the way, we add a condition to check whether resizing functions are NULL before cancelling the work, avoiding to cancel an uninitialized work. Lastly, while we wait for all work items we submitted before to run to completion with cancel_delayed_work(), ht->mutex has been taken in rhashtable_destroy(). Moreover, cancel_delayed_work() doesn't return until all work items are accomplished, and when work items are scheduled, the work's function - rht_deferred_worker() will be called. However, as rht_deferred_worker() also needs to acquire the lock, deadlock might happen at the moment as the lock is already held before. So if the cancel work function is moved out of the lock covered scope, this will avoid the deadlock. Fixes: 97defe1e ("rhashtable: Per bucket locks & deferred expansion/shrinking") Signed-off-by:

Merge tag 'mac80211-next-for-davem-2015-01-15' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next Here's a big pile of changes for this round. We have * a lot of regulatory code changes to deal with the way newer Intel devices handle this * a change to drop packets while disconnecting from an AP instead of trying to wait for them * a new attempt at improving the tailroom accounting to not kick in too much for performance reasons * improvements in wireless link statistics * many other small improvements and small fixes that didn't seem necessary for 3.19 (e.g. in hwsim which is testing only code) Conflicts: drivers/staging/rtl8723au/os_dep/ioctl_cfg80211.c Minor overlapping changes.

RAW sockets with hdrinc suffer from contention on rt_uncached_lock spinlock. One solution is to use percpu lists, since most routes are destroyed by the cpu that created them. It is unclear why we even have to put these routes in uncached_list, as all outgoing packets should be freed when a device is dismantled. Signed-off-by:

Thomas Graf says: ==================== VXLAN Group Policy Extension Implements supports for the Group Policy VXLAN extension [0] to provide a lightweight and simple security label mechanism across network peers based on VXLAN. The security context and associated metadata is mapped to/from skb->mark. This allows further mapping to a SELinux context using SECMARK, to implement ACLs directly with nftables, iptables, OVS, tc, etc. The extension is disabled by default and should be run on a distinct port in mixed Linux VXLAN VTEP environments. Liberal VXLAN VTEPs which ignore unknown reserved bits will be able to receive VXLAN-GBP frames. Simple usage example: 10.1.1.1: # ip link add vxlan0 type vxlan id 10 remote 10.1.1.2 gbp # iptables -I OUTPUT -m owner --uid-owner 101 -j MARK --set-mark 0x200 10.1.1.2: # ip link add vxlan0 type vxlan id 10 remote 10.1.1.1 gbp # iptables -I INPUT -m mark --mark 0x200 -j DROP iproute2 [1] and OVS [2] support will be provided in separate patches.

Introduces support for the group policy extension to the VXLAN virtual port. The extension is disabled by default and only enabled if the user has provided the respective configuration. ovs-vsctl add-port br0 vxlan0 -- \ set Interface vxlan0 type=vxlan options:exts=gbp The configuration interface to enable the extension is based on a new attribute OVS_VXLAN_EXT_GBP nested inside OVS_TUNNEL_ATTR_EXTENSION which can carry additional extensions as needed in the future. The group policy metadata is stored as binary blob (struct ovs_vxlan_opts) internally just like Geneve options but transported as nested Netlink attributes to user space. Renames the existing TUNNEL_OPTIONS_PRESENT to TUNNEL_GENEVE_OPT with the binary value kept intact, a new flag TUNNEL_VXLAN_OPT is introduced. The attributes OVS_TUNNEL_KEY_ATTR_VXLAN_OPTS and existing OVS_TUNNEL_KEY_ATTR_GENEVE_OPTS are implemented mutually exclusive. Signed-off-by: -

A VXLAN net_device looking for an appropriate socket may only consider a socket which has a matching set of flags/extensions enabled. If incompatible flags are enabled, return a conflict to have the caller create a distinct socket with distinct port. The OVS VXLAN port is kept unaware of extensions at this point. Signed-off-by:

Implements supports for the Group Policy VXLAN extension [0] to provide a lightweight and simple security label mechanism across network peers based on VXLAN. The security context and associated metadata is mapped to/from skb->mark. This allows further mapping to a SELinux context using SECMARK, to implement ACLs directly with nftables, iptables, OVS, tc, etc. The group membership is defined by the lower 16 bits of skb->mark, the upper 16 bits are used for flags. SELinux allows to manage label to secure local resources. However, distributed applications require ACLs to implemented across hosts. This is typically achieved by matching on L2-L4 fields to identify the original sending host and process on the receiver. On top of that, netlabel and specifically CIPSO [1] allow to map security contexts to universal labels. However, netlabel and CIPSO are relatively complex. This patch provides a lightweight alternative for overlay network environments with a trusted underlay. No additional control protocol is required. Host 1: Host 2: Group A Group B Group B Group A +-----+ +-------------+ +-------+ +-----+ | lxc | | SELinux CTX | | httpd | | VM | +--+--+ +--+----------+ +---+---+ +--+--+ \---+---/ \----+---/ | | +---+---+ +---+---+ | vxlan | | vxlan | +---+---+ +---+---+ +------------------------------+ Backwards compatibility: A VXLAN-GBP socket can receive standard VXLAN frames and will assign the default group 0x0000 to such frames. A Linux VXLAN socket will drop VXLAN-GBP frames. The extension is therefore disabled by default and needs to be specifically enabled: ip link add [...] type vxlan [...] gbp In a mixed environment with VXLAN and VXLAN-GBP sockets, the GBP socket must run on a separate port number. Examples: iptables: host1# iptables -I OUTPUT -m owner --uid-owner 101 -j MARK --set-mark 0x200 host2# iptables -I INPUT -m mark --mark 0x200 -j DROP OVS: # ovs-ofctl add-flow br0 'in_port=1,actions=load:0x200->NXM_NX_TUN_GBP_ID[],NORMAL' # ovs-ofctl add-flow br0 'in_port=2,tun_gbp_id=0x200,actions=drop' [0] https://tools.ietf.org/html/draft-smith-vxlan-group-policy [1] http://lwn.net/Articles/204905/Signed-off-by: -
