2016-04-17macsec: fix crypto Kconfig dependencyArnd Bergmann
The new MACsec driver uses the AES crypto algorithm, but can be configured even if CONFIG_CRYPTO is disabled, leading to a build error: warning: (MAC80211 && MACSEC) selects CRYPTO_GCM which has unmet direct dependencies (CRYPTO) warning: (BT && CEPH_LIB && INET && MAC802154 && MAC80211 && BLK_DEV_RBD && MACSEC && AIRO_CS && LIBIPW && HOSTAP && USB_WUSB && RTLLIB_CRYPTO_CCMP && FS_ENCRYPTION && EXT4_ENCRYPTION && CEPH_FS && BIG_KEYS && ENCRYPTED_KEYS) selects CRYPTO_AES which has unmet direct dependencies (CRYPTO) crypto/built-in.o: In function `gcm_enc_copy_hash': aes_generic.c:(.text+0x2b8): undefined reference to `crypto_xor' aes_generic.c:(.text+0x2dc): undefined reference to `scatterwalk_map_and_copy' This adds an explicit 'select CRYPTO' statement the way that other drivers handle it.

2016-04-16nfp: add async reconfiguration mechanismJakub Kicinski
Some callers of nfp_net_reconfig() are in atomic context so we used to busy wait for commands to complete. In worst case scenario that means locking up a core for up to 5 seconds when a command times out. Lets add a timer-based mechanism of asynchronously checking whether reconfiguration completed successfully for atomic callers to use. Non-atomic callers can now just sleep. The approach taken is quite simple because (1) synchronous reconfigurations always happen under RTNL (or before device is registered); (2) we can coalesce pending reconfigs. There is no need for request queues, timer which eventually takes a look at reconfiguration result to report errors is good enough.

2016-04-16nfp: remove buggy RX buffer length validationJakub Kicinski
Meaning of data_len and meta_len RX WB descriptor fields is slightly confusing. Add a comment with a diagram clarifying the layout. Also remove the buffer length validation: (a) it's imprecise for static rx-offsets; (b) if firmware is buggy enough to DMA past the end of the buffer WARN_ON_ONCE() doesn't seem like a strong enough response. skb_put() will do the checking for us anyway.

2016-04-16stmmac: socfpga: remove extra call to socfpga_dwmac_setupDinh Nguyen
In the socfpga_dwmac_probe function, we have a call to socfpga_dwmac_setup, which is already called from socfpga_dwmac_init later in the probe function. Remove this extra call to socfpga_dwmac_setup. Also we should not be calling socfpga_dwmac_setup() directly without wrapping it around the proper reset assert/deasserts. That is because the socfpga_dwmac_setup() is setting up PHY modes in the system manager, and it is requires the EMAC's to be in reset during the PHY setup.

2016-04-16ip_tunnel_core: iptunnel_handle_offloads returns int and doesn't free skbAlexander Duyck
This patch updates the IP tunnel core function iptunnel_handle_offloads so that we return an int and do not free the skb inside the function. This actually allows us to clean up several paths in several tunnels so that we can free the skb at one point in the path without having to have a secondary path if we are supporting tunnel offloads. In addition it should resolve some double-free issues I have found in the tunnels paths as I believe it is possible for us to end up triggering such an event in the case of fou or gue.

2016-04-16net: dsa: mv88e6xxx: share the same default FDBVivien Didelot
For hardware cross-chip bridging to work, user ports *and* DSA ports need to share a common address database, in order to switch a frame to the correct interconnected device. This is currently working for VLAN filtering aware systems, since Linux will implement a bridge group as a 802.1Q VLAN, which has its own FDB, including DSA and CPU links as members. However when the system doesn't support VLAN filtering, Linux only relies on the port-based VLAN to implement a bridge group. To fix hardware cross-chip bridging for such systems, set the same default address database 0 for user and DSA ports, instead of giving them all a different default database. Note that the bridging code prevents frames to egress between unbridged ports, and flushes FDB entries of a port when changing its STP state. Also note that the FID 0 is special and means "all" for ATU operations, but it's OK since it is used as a default forwarding address database. Fixes: 2db9ce1fd9a3 ("net: dsa: mv88e6xxx: assign default FDB to ports") Fixes: 466dfa077022 ("net: dsa: mv88e6xxx: assign dynamic FDB to bridges") Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.

2016-04-16net: dsa: mv88e6xxx: enable SA learning on DSA portsVivien Didelot
In multi-chip systems, DSA Tag ports must learn SA addresses in order to correctly switch frames between interconnected chips. This fixes cross-chip hardware bridging in a VLAN filtering aware system, because a bridge group gets implemented as an hardware 802.1Q VLAN and thus DSA and user ports share the same FDB.

Locking a port generates an hardware interrupt when a new SA address is received. This enables CPU directed learning, which is needed for 802.1X MAC authentication. To disable automatic learning on a port, the only configuration needed is to set its Port Association Vector to all zero. Clear PAV when SA learning should be disabled instead of locking a port.

This adds support for W5200 chip. W5100 and W5200 have similar memory map although some of their offsets are different. The register access sequences between them are different but w5100 driver has abstraction layer for difference bus interface modes so it is easy to add W5200 support to w5100 and w5100-spi drivers.

2016-04-16net: w5100: enable to support sleepable register access interfaceAkinobu Mita
SPI transfer routines are callable only from contexts that can sleep. This adds ability to tell the core driver that the interface mode cannot access w5100 register on atomic contexts. In this case, workqueue and threaded irq are required. This also corrects timeout period waiting for command register to be automatically cleared because the latency of the register access with SPI transfer can be interfered by other contexts.

2016-04-16net: w5100: add ability to support other bus interfaceAkinobu Mita
The w5100 driver currently only supports direct and indirect bus interface mode which use MMIO space for accessing w5100 registers. In order to support SPI interface mode which is supported by W5100 chip, this makes the bus interface abstraction layer more generic so that separated w5100-spi driver can use w5100 driver as core module.

2016-04-16vxlan: synchronously and race-free destruction of vxlan socketsHannes Frederic Sowa
Due to the fact that the udp socket is destructed asynchronously in a work queue, we have some nondeterministic behavior during shutdown of vxlan tunnels and creating new ones. Fix this by keeping the destruction process synchronous in regards to the user space process so IFF_UP can be reliably set. udp_tunnel_sock_release destroys vs->sock->sk if reference counter indicates so. We expect to have the same lifetime of vxlan_sock and vxlan_sock->sock->sk even in fast paths with only rcu locks held. So only destruct the whole socket after we can be sure it cannot be found by searching vxlan_net->sock_list.

2016-04-15qlge: Replace create_singlethread_workqueue with alloc_ordered_workqueueAmitoj Kaur Chawla
Replace deprecated create_singlethread_workqueue with alloc_ordered_workqueue. Work items include getting tx/rx frame sizes, resetting MPI processor, setting asic recovery bit so ordering seems necessary as only one work item should be in queue/executing at any given time, hence the use of alloc_ordered_workqueue. WQ_MEM_RECLAIM flag has been set since ethernet devices seem to sit in memory reclaim path, so to guarantee forward progress regardless of memory pressure.

2016-04-15rtl8xxxu: Pause TX before calling disable_rf()Jes Sorensen

2016-04-15rtl8xxxu: Implement rtl8192e_enable_rf()Jes Sorensen
This implements an 8192eu specific enable_rf() function. The 8192eu is not a combo device, so no need for doing the BT specific bits needed by the 8723bu. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2016-04-15rtl8xxxu: Fix OOPS if user tries to add device via /sysJes Sorensen
This driver relies on driver_info in struct usb_device_id, so allowing adding a device via /sys/bus/usb/drivers/rtl8xxxu/new_id will cause a NULL pointer dereference. Set .no_dynamic_id = 1 to disable hot add of USB IDs.
