rocker: rename rocker.c to rocker_main.c

2016-02-18T04:08:34+00:00

Since "rocker.c" is going to be split into multiple files, start with renaming original "rocker.c" file to "rocker_main.c". Multiple code parts are going to be cut from "rocker_main.c" later on. Fix couple of checkpatch issues on the way. Signed-off-by: Jiri Pirko Acked-by: Scott Feldman Signed-off-by: David S. Miller

rocker: rename rocker.h to rocker_hw.h

2016-02-18T04:08:34+00:00

Since "rocker.h" file is going to be used for different purpose, rename the hardware-specific header to "rocker_hw.h". Signed-off-by: Jiri Pirko Acked-by: Scott Feldman Signed-off-by: David S. Miller

rocker: remove unused rocker_port param from alloc funcs and shorten their names

2016-02-18T04:08:34+00:00

No need to pass rocker_port around to alloc/free rocker functions, since they now use switchdev_trans for memory management storage. With the param removal, shorten the name of the functions since they now has nothing to do with rocker port. Signed-off-by: Jiri Pirko Acked-by: Scott Feldman Signed-off-by: David S. Miller

switchdev: Require RTNL mutex to be held when sending FDB notifications

2016-01-29T00:21:31+00:00

When switchdev drivers process FDB notifications from the underlying device they resolve the netdev to which the entry points to and notify the bridge using the switchdev notifier. However, since the RTNL mutex is not held there is nothing preventing the netdev from disappearing in the middle, which will cause br_switchdev_event() to dereference a non-existing netdev. Make switchdev drivers hold the lock at the beginning of the notification processing session and release it once it ends, after notifying the bridge. Also, remove switchdev_mutex and fdb_lock, as they are no longer needed when RTNL mutex is held.

net: add netif_tx_napi_add()

2015-11-18T21:17:41+00:00

netif_tx_napi_add() is a variant of netif_napi_add() It should be used by drivers that use a napi structure to exclusively poll TX. We do not want to add this kind of napi in napi_hash[] in following patches, adding generic busy polling to all NAPI drivers. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

Merge tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

2015-11-06T22:22:15+00:00

Pull asm-generic cleanups from Arnd Bergmann: "The asm-generic changes for 4.4 are mostly a series from Christoph Hellwig to clean up various abuses of headers in there. The patch to rename the io-64-nonatomic-*.h headers caused some conflicts with new users, so I added a workaround that we can remove in the next merge window. The only other patch is a warning fix from Marek Vasut" * tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: asm-generic: temporarily add back asm-generic/io-64-nonatomic*.h asm-generic: cmpxchg: avoid warnings from macro-ized cmpxchg() implementations gpio-mxc: stop including n_tracesink: stop including n_tracerouter: stop including mlx5: stop including hifn_795x: stop including drbd: stop including move count_zeroes.h out of asm-generic move io-64-nonatomic*.h out of asm-generic

rocker: remove nowait from switchdev callbacks.

2015-10-15T13:09:51+00:00

No need to avoid sleeping in switchdev callbacks now, as the switchdev core allows it. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

switchdev: remove pointers from switchdev objects

2015-10-15T13:09:49+00:00

When object is used in deferred work, we cannot use pointers in switchdev object structures because the memory they point at may be already used by someone else. So rather do local copy of the value.
