net: correct check in dev_addr_del()

2012-11-15T22:57:53Z

Check (ha->addr == dev->dev_addr) is always true because dev_addr_init() sets this. Correct the check to behave properly on addr removal. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

net: addr_list: add exclusive dev_uc_add and dev_mc_add

2012-04-15T17:06:04Z

This adds a dev_uc_add_excl() and dev_mc_add_excl() calls similar to the original dev_{uc|mc}_add() except it sets the global bit and returns -EEXIST for duplicat entires. This is useful for drivers that support SR-IOV, macvlan devices and any other devices that need to manage the unicast and multicast lists. v2: fix typo UNICAST should be MULTICAST in dev_mc_add_excl() CC: Ben Hutchings Signed-off-by: John Fastabend Signed-off-by: David S.

net: fix /proc/net/dev regression

2012-04-03T21:23:23Z

Commit f04565ddf52 (dev: use name hash for dev_seq_ops) added a second regression, as some devices are missing from /proc/net/dev if many devices are defined. When seq_file buffer is filled, the last ->next/show() method is canceled (pos value is reverted to value prior ->next() call) Problem is after above commit, we dont restart the lookup at right position in ->start() method. Fix this by removing the internal 'pos' pointer added in commit, since we need to use the 'loff_t *pos' provided by seq_file layer. This also reverts commit 5cac98dd0 (net: Fix corruption in /proc/*/net/dev_mcast), since its not needed anymore.

net: introduce netif_addr_lock_nested() and call if when appropriate

2012-01-09T20:46:58Z

dev_uc_sync() and dev_mc_sync() are acquiring netif_addr_lock for destination device of synchronization. Since netif_addr_lock is already held at the time for source device, this triggers lockdep deadlock warning. There's no way this deadlock can happen so use spin_lock_nested() to silence the warning.

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30Z

These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere. Signed-off-by: Paul Gortmaker

net,rcu: convert call_rcu(ha_rcu_free) to kfree_rcu()

2011-05-08T05:50:52Z

The rcu callback ha_rcu_free() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(ha_rcu_free). Signed-off-by: Lai Jiangshan Acked-by: David S. Miller Signed-off-by: Paul E. McKenney Reviewed-by: Josh Triplett
