For most pre-5705 devices, multiple link interrupts were being generated for a single physical link change. The source of the interrupts was determined to be unnecessary toggling of the MAC link polarity bit. This patch changes the way the link polarity bit gets configured. Where possible, code that dynamically configures the bit in response to link changes has been replaced by code that configures the bit once during initialization time and then leaves the bit alone. For correctness, this patch also limits the use of the bit to those devices where it is defined, namely devices before the 5705. This patch also corrects the link polarity configurations for 5700 devices when paired against a bcm5411 phy.

Gagan Arneja <gaagaan@gmail.com> pointed out that tg3_reset_task() could potentially race with another thread calling tg3_full_lock() such as the ethtool_set_xxx() functions. This may trigger the BUG_ON() in tg3_irq_quiesce() or cause the irq_sync flag to be out- of-sync. I think the easiest way to fix this is to get the tp->lock first before setting the irq_sync flag. This is safe to do because the tp->lock is never grabbed by the irq handler. This change will guarantee that the irq_sync flag updates will be serialized. We also have to change one spot to call tg3_netif_start() (which clears the irq_sync flag) before releasing the tp->lock. Signed-off-by: NMichael Chan <mchan@broadcom.com> Signed-off-by: NDavid S.

Switch from formatting messages in probe routine and copying with kfifo, to using a small circular queue of information and formatting on read. This avoids wraparound issues with kfifo, and saves one copy. Also make sure to state correct license, rather than copying off some other driver I started with.

All drivers need to unregister their devices in the module unload function. While doing so they must hold the rtnl and atomically unregister the rtnl_link ops as well. This makes the rtnl_link_unregister function that takes the rtnl itself completely useless. Provide default newlink/dellink functions, make __rtnl_link_unregister and rtnl_link_unregister unregister all devices with matching rtnl_link_ops and change the existing users to take advantage of that.

The VLAN MAC address handling is broken in multiple ways. When the address differs when setting it, the real device is put in promiscous mode twice, but never taken out again. Additionally it doesn't resync when the real device's address is changed and needlessly puts it in promiscous mode when the vlan device is still down. Fix by moving address handling to vlan_dev_open/vlan_dev_stop and properly deal with address changes in the device notifier. Also switch to dev_unicast_add (which needs the exact same handling). Since the set_mac_address handler is identical to the generic ethernet one with these changes, kill it and use ether_setup().

Throw out the old mark & sweep garbage collector and put in a refcounting cycle detecting one. The old one had a race with recvmsg, that resulted in false positives and hence data loss. The old algorithm operated on all unix sockets in the system, so any additional locking would have meant performance problems for all users of these. The new algorithm instead only operates on "in flight" sockets, which are very rare, and the additional locking for these doesn't negatively impact the vast majority of users. In fact it's probable, that there weren't *any* heavy senders of sockets over sockets, otherwise the above race would have been discovered long ago. The patch works OK with the app that exposed the race with the old code. The garbage collection has also been verified to work in a few simple cases.

The "fix" for emerging security threat was overkill and it broke basic semantic of IPv6 routing header processing. We should assume RT0 (or even RT2, depends on configuration) as "unknown" RH type so that we - silently ignore the routing header if segleft == 0 - send ICMPv6 Parameter Problem message back to the sender, otherwise.

93ec2c72 applied excessive duct tape to the netpoll beast's netpoll_cleanup(), thus substituting one leak with another, and opening up a little buglet :-) net_device->npinfo (netpoll_info) is a shared and refcounted object and cannot simply be set NULL the first time netpoll_cleanup() is called. Otherwise, further netpoll_cleanup()'s see np->dev->npinfo == NULL and become no-ops, thus leaking. And it's a bug too: the first call to netpoll_cleanup() would thus (annoyingly) "disable" other (still alive) netpolls too. Maybe nobody noticed this because netconsole (only user of netpoll) never supported multiple netpoll objects earlier. This is a trivial and obvious one-line fixlet.

Document the expectations about device MTU handling. The documentation about oversize packet handling is probably too loose. IMHO devices should drop oversize packets for robustness, but many devices allow it now. For example, if you set mtu to 1200 bytes, most ether devices will allow a 1500 byte frame in.
