2017-02-14Merge branch 'bridge-fdb-minor-cleanup'David S. Miller
Nikolay Aleksandrov says: ==================== bridge: minor fdb cleanup These patches aim to simplify the bridge fdb API a little by removing some redundant functions and converting them into wrappers of a single function. Also add proper lock checking to avoid future mistakes for the search functions. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2017-02-14bridge: fdb: converge fdb_delete_by functions into oneNikolay Aleksandrov
We can simplify the logic of entries pointing to the bridge by converging the fdb_delete_by functions, this would allow us to use the same function for both cases since the fdb's dst is set to NULL if it is pointing to the bridge thus we can always check for a port match.

2017-02-14bridge: fdb: add proper lock checks in searching functionsNikolay Aleksandrov

2017-02-14bridge: fdb: converge fdb searching functions into oneNikolay Aleksandrov
Before this patch we had 3 different fdb searching functions which was confusing. This patch reduces all of them to one - fdb_find_rcu(), and two flavors: br_fdb_find() which requires hash_lock and br_fdb_find_rcu which requires RCU. This makes it clear what needs to be used, we also remove two abusers of __br_fdb_get which called it under hash_lock and replace them with br_fdb_find().

2017-02-14ath10k: fix napi crash during rmmod when probe firmware failsKalle Valo
This fixes the below crash when ath10k probe firmware fails, NAPI polling tries to access a rx ring resource which was never allocated. An easy way to reproduce this is easy to remove all the firmware files, load ath10k modules and ath10k will crash when calling 'rmmod ath10k_pci'. The fix is to call napi_enable() from ath10k_pci_hif_start() so that it matches with napi_disable() being called from ath10k_pci_hif_stop(). Big thanks to Mohammed Shafi Shajakhan who debugged this and provided first version of the fix. In this patch I just fix the actual problem in pci.c instead of having a workaround in core.c.

2017-02-14Merge branch 'ipv6-v4mapped'David S. Miller
Jonathan T. Leighton says: ==================== IPv4-mapped on wire, :: dst address issue Under some circumstances IPv6 datagrams are sent with IPv4-mapped IPv6 addresses as the source. Given an IPv6 socket bound to an IPv4-mapped IPv6 address, and an IPv6 destination address, both TCP and UDP will will send packets using the IPv4-mapped IPv6 address as the source. Per RFC 6890 (Table 20), IPv4-mapped IPv6 source addresses are not allowed in an IP datagram. The problem can be observed by attempting to connect() either a TCP or UDP socket, or by using sendmsg() with a UDP socket. The patch is intended to correct this issue for all socket types. linux follows the BSD convention that an IPv6 destination address specified as in6addr_any is converted to the loopback address. Currently, neither TCP nor UDP consider the possibility that the source address is an IPv4-mapped IPv6 address, and assume that the appropriate loopback address is ::1. The patch adds a check on whether or not the source address is an IPv4-mapped IPv6 address and then sets the destination address to either ::ffff:127.0.0.1 or ::1, as appropriate. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2017-02-14ipv6: Handle IPv4-mapped src to in6addr_any dst.Jonathan T. Leighton
This patch adds a check on the type of the source address for the case where the destination address is in6addr_any. If the source is an IPv4-mapped IPv6 source address, the destination is changed to ::ffff:127.0.0.1, and otherwise the destination is changed to ::1. This is done in three locations to handle UDP calls to either connect() or sendmsg() and TCP calls to connect(). Note that udpv6_sendmsg() delays handling an in6addr_any destination until very late, so the patch only needs to handle the case where the source is an IPv4-mapped IPv6 address.

2017-02-14spi: lantiq-ssc: add support for Lantiq SSC SPI controllerHauke Mehrtens
This driver supports the Lantiq SSC SPI controller in master mode. This controller is found on Intel (former Lantiq) SoCs like the Danube, Falcon, xRX200, xRX300. The hardware uses two hardware FIFOs one for received and one for transferred bytes. When the driver writes data into the transmit FIFO the complete word is taken from the FIFO into a shift register. The data from this shift register is then written to the wire. This driver uses the interrupts signaling the status of the FIFOs and not the shift register. It is also possible to use the interrupts for the shift register, but they will send a signal after every word. When using the interrupts for the shift register we get a signal when the last word is written into the shift register and not when it is written to the wire. After all FIFOs are empty the driver busy waits till the hardware is not busy any more and returns the transfer status.

2017-02-14IB/mlx4: Take source GID by index from HW GID tableTalat Batheesh
Previously, we used the HW GID index in order to search the source GID in the software GID cached table. In some cases, for example when the MAC Address of the network interface is changed, the GID cached table saves the old-IPv6-link-local GID at the end of the table. When returning the old MAC address, the software GID cached table tries to add the new IPv6-link-local GID, and when it identifies that the GID already exists, the software GID cached does not add it. Thus a mismatch occurs between the HW and the SW GID tables. It resulted with sending traffic with the wrong source GID. This commit fixes the issue by taking both from the HW table. The problem can be reproduced with the following scenario: Client: # ifconfig ens6 2.2.2.5 # ifconfig ens6 inet6 add 2001:0db8:0:f101::5/64 # ifconfig ens6 hw ether f4:52:14:61:a0:71 # ifconfig ens6 inet6 del 2001:0db8:0:f101::5/64 # ifconfig ens6 inet6 add 2001:0db8:0:f101::5/64 # ucmatose -f ipv6 -b 2001:0db8:0:f101::5 -s 2001:0db8:0:f101::6 -p 20156 Server: # ucmatose -f ipv6 -b 2001:0db8:0:f101::6 -p 20156 Fixes: 4c3eb3ca1396 ('IB/mlx4: Add VLAN support for IBoE') Signed-off-by: Talat Batheesh <talatb@mellanox.com> Reviewed-by: Maor Gottlieb <maorg@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>

2017-02-14IB: Query ports via the core instead of direct into the driverOr Gerlitz

Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers.
