s390: remove unneeded variables

2015-08-07T07:57:01+00:00

This patch remove unneeded variables used to store return values. These issues were detected with the Coccinelle script: scripts/coccinelle/misc/returnvar.cocci [heiko.carstens@de.ibm.com]: make qeth_l[2/3]_stop() return void Signed-off-by: Peter Senna Tschudin Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

s390/lcs: Fix null-pointer access in msg

2015-05-18T16:14:18+00:00

An attempt to configure a CTC device as LCS results in the following error message: (null): Detecting a network adapter for LCS devices failed with rc=-5 (0xfffffffb) "(null)" results from access to &card->dev->dev in lcs_new_device() which is only initialized later in the function. Fix this by using &ccwgdev->dev instead which is initialized before lcs_new_device() is called. Signed-off-by: Peter Oberparleiter Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

qeth: replace ENOSYS with EOPNOTSUPP

2015-05-18T16:14:17+00:00

Since recently, `checkpatch.pl` advices that ENOSYS should not be used for anything other than "invalid syscall nr". This patch replaces ENOSYS return code with EOPNOTSUPP for the "unsupported function" conditions. Signed-off-by: Eugene Crosser Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

qeth: BRIDGEPORT "sanity check"

2015-05-18T16:14:17+00:00

Forbid enabling IFF_PROMISC reflection to BRIDGEPORT when a role is already assigned, and forbid direct manipulation of the role when reflection mode is engaged. Reviewed-by: Thomas Richter Signed-off-by: Eugene Crosser Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

qeth: OSA version of SETBRIDGEPORT command

2015-05-18T16:14:17+00:00

OSA Ethernet hardware is introducing BRIDGEPORT functionality similar (but not identical) to HiperSockets BRIDGEPORT. This patch makes HiperSockets BRIDGEPORT related sysfs attributes and udev events work with OSA hardware too.

qeth: IFF_PROMISC flag to BRIDGE PORT mode

2015-05-18T16:14:17+00:00

OSA and HiperSocket devices do not support promiscuous mode proper, but they support "BRIDGE PORT" mode that is functionally similar. This update introduces sysfs attribute that, when set, makes the driver try to "reflect" setting and resetting of the IFF_PROMISC flag on the interface into setting and resetting PRIMARY or SECONDARY bridge port role on the underlying OSA or HiperSocket device.

qeth: remove locks from sysfs _show

2015-05-18T16:14:17+00:00

Locking is probably unnecessary in this case, and the rest of the qeth sysfs code does not use locks in the *_show() functions. Remove locks from the layer2 *_show() functions in which they where accidentally introduced. Signed-off-by: Eugene Crosser Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

qeth: fix handling of IPA return codes

2015-05-18T16:14:17+00:00

Function that executes IPA commands returns the result code from the IPA response block. If non-negative, it needs to be transformed into errno-compatible code before returning to the caller. Signed-off-by: Eugene Crosser Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

qeth: fix rx checksum offload handling

2015-05-18T16:14:16+00:00

ethtool is used to change some device driver features such as RX/TX hardware checksum offloading. The qeth device driver callback function to turn on/off RX hardware check sum handling never changes the hardware configuration. The NETIF_F_RXCSUM bit is cleared when the feature bitset type netdev_features_t(64bit) is assigned to 32 a bit variable. This patch fixes the NETIF_F_RXCSUM handling. Also there is no need to manipulate the device's features bit set as this is done by the caller when no error occurs. Signed-off-by: Thomas Richter Signed-off-by: Ursula Braun Signed-off-by: David S.

Pull networking updates from David Miller: 1) Add BQL support to via-rhine, from Tino Reichardt. 2) Integrate SWITCHDEV layer support into the DSA layer, so DSA drivers can support hw switch offloading. From Floria Fainelli. 3) Allow 'ip address' commands to initiate multicast group join/leave, from Madhu Challa. 4) Many ipv4 FIB lookup optimizations from Alexander Duyck. 5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel Borkmann. 6) Remove the ugly compat support in ARP for ugly layers like ax25, rose, etc. And use this to clean up the neigh layer, then use it to implement MPLS support. All from Eric Biederman. 7) Support L3 forwarding offloading in switches, from Scott Feldman. 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed up route lookups even further. From Alexander Duyck. 9) Many improvements and bug fixes to the rhashtable implementation, from Herbert Xu and Thomas Graf. In particular, in the case where an rhashtable user bulk adds a large number of items into an empty table, we expand the table much more sanely. 10) Don't make the tcp_metrics hash table per-namespace, from Eric Biederman. 11) Extend EBPF to access SKB fields, from Alexei Starovoitov. 12) Split out new connection request sockets so that they can be established in the main hash table. Much less false sharing since hash lookups go direct to the request sockets instead of having to go first to the listener then to the request socks hashed underneath. From Eric Dumazet. 13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk. 14) Support stable privacy address generation for RFC7217 in IPV6. From Hannes Frederic Sowa. 15) Hash network namespace into IP frag IDs, also from Hannes Frederic Sowa. 16) Convert PTP get/set methods to use 64-bit time, from Richard Cochran. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1816 commits) fm10k: Bump driver version to 0.15.2 fm10k: corrected VF multicast update fm10k: mbx_update_max_size does not drop all oversized messages fm10k: reset head instead of calling update_max_size fm10k: renamed mbx_tx_dropped to mbx_tx_oversized fm10k: update xcast mode before synchronizing multicast addresses fm10k: start service timer on probe fm10k: fix function header comment fm10k: comment next_vf_mbx flow fm10k: don't handle mailbox events in iov_event path and always process mailbox fm10k: use separate workqueue for fm10k driver fm10k: Set PF queues to unlimited bandwidth during virtualization fm10k: expose tx_timeout_count as an ethtool stat fm10k: only increment tx_timeout_count in Tx hang path fm10k: remove extraneous "Reset interface" message fm10k: separate PF only stats so that VF does not display them fm10k: use hw->mac.max_queues for stats fm10k: only show actual queues, not the maximum in hardware fm10k: allow creation of VLAN on default vid fm10k: fix unused warnings ...
