2009-07-03qlge: Clear frame to queue routing before reset.Ron Mercer
Not clearing the routing bits can cause frames to erroneously get routed to management processor. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-07-03qlge: Expand coverage of hw lock for config register.Ron Mercer
The hardware semaphore covers the configuration register as well as the ICB registers. The ICB high and low regs contain the address of the initialization control block and the config register is used to signal the hardware that a block is ready to be downloaded. Currently we were only protecting the ICB regs. This changes expands to cover the config register as well. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: David S.

2009-07-03IPv6: preferred lifetime of address not getting updatedBrian Haley
There's a bug in addrconf_prefix_rcv() where it won't update the preferred lifetime of an IPv6 address if the current valid lifetime of the address is less than 2 hours (the minimum value in the RA). For example, If I send a router advertisement with a prefix that has valid lifetime = preferred lifetime = 2 hours we'll build this address: 3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000 inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic valid_lft 7175sec preferred_lft 7175sec If I then send the same prefix with valid lifetime = preferred lifetime = 0 it will be ignored since the minimum valid lifetime is 2 hours: 3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000 inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic valid_lft 7161sec preferred_lft 7161sec But according to RFC 4862 we should always reset the preferred lifetime even if the valid lifetime is invalid, which would cause the address to immediately get deprecated. So with this patch we'd see this: 5: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000 inet6 2001:1890:1109:a20:21f:29ff:fe5a:ef04/64 scope global deprecated dynamic valid_lft 7163sec preferred_lft 0sec The comment winds-up being 5x the size of the code to fix the problem. Update the preferred lifetime of IPv6 addresses derived from a prefix info option in a router advertisement even if the valid lifetime in the option is invalid, as specified in RFC 4862 Section 5.5.3e. Fixes an issue where an address will not immediately become deprecated. Reported by Jens Rosenboom. Signed-off-by: Brian Haley <brian.haley@hp.com> Signed-off-by: David S.

2009-07-02phylib: fixes for PHY_RESUMING state changesWade Farnsworth
The PHY_HALTED state disables phydev->link, but the link will not be updated upon entering PHY_RESUMING. Add a call to phy_read_status() to update the link before entering PHY_RUNNING. If the link is not up at this point, enter the PHY_NOLINK state instead. Also, when transitioning from PHY_RESUMING to PHY_RUNNING, calls to netif_carrier_on() and phydev->adjust_link() are missing.

Restrict firmware reset to following cases - o chip rev is NX2031 (firmare doesn't support heartbit). o firmware is dead. o previous attempt to init firmware had failed. o we have got newer file firmware.

2009-06-30Revert "ipv4: arp announce, arp_proxy and windows ip conflict verification"Eric W. Biederman
This reverts commit 73ce7b01b4496a5fbf9caf63033c874be692333f. After discovering that we don't listen to gratuitious arps in 2.6.30 I tracked the failure down to this commit. The patch makes absolutely no sense. RFC2131 RFC3927 and RFC5227. are all in agreement that an arp request with sip == 0 should be used for the probe (to prevent learning) and an arp request with sip == tip should be used for the gratitous announcement that people can learn from. It appears the author of the broken patch got those two cases confused and modified the code to drop all gratuitous arp traffic. Ouch! Cc: stable@kernel.org Signed-off-by: Eric W.

2009-06-26inet: Call skb_orphan before tproxy activatesHerbert Xu
As transparent proxying looks up the socket early and assigns it to the skb for later processing, we must drop any existing socket ownership prior to that in order to distinguish between the case where tproxy is active and where it is not.

2009-06-26mac80211: Use rcu_barrier() on unload.Jesper Dangaard Brouer
The mac80211 module uses rcu_call() thus it should use rcu_barrier() on module unload. The rcu_barrier() is placed in mech.c ieee80211_stop_mesh() which is invoked from ieee80211_stop() in case vif.type == NL80211_IFTYPE_MESH_POINT. Acked-by: Paul E.

2009-06-26sunrpc: Use rcu_barrier() on unload.Jesper Dangaard Brouer
The sunrpc module uses rcu_call() thus it should use rcu_barrier() on module unload. Have not verified that the possibility for new call_rcu() callbacks has been disabled. As a hint for checking, the functions calling call_rcu() (unx_destroy_cred and generic_destroy_cred) are registered as crdestroy function pointer in struct rpc_credops. Acked-by: Paul E.

2009-06-26bridge: Use rcu_barrier() instead of syncronize_net() on unload.Jesper Dangaard Brouer
When unloading modules that uses call_rcu() callbacks, then we must use rcu_barrier(). This module uses syncronize_net() which is not enough to be sure that all callback has been completed.
