* e1000: fix screaming IRQAnupam Chanda2010-11-211-4/+8
| | | | | | | | | | | | | | | | | VMWare reports that the e1000 driver has a bug when bringing down the interface, such that interrupts are not disabled in the hardware but the driver stops reporting that it consumed the interrupt. The fix is to set the driver's "down" flag later in the routine, after all the timers and such have exited, preventing the interrupt handler from being called and exiting early without handling the interrupt.

* be2net: Fix to avoid firmware update when interface is not open.Sarveshwar Bandi2010-11-191-0/+6
| | | | | | | | | | Since interrupts are enabled only when open is called on the interface, Attempting a firmware update operation when interface is down could lead to partial success or failure of operation. This fix fails the request if netif_running is false. Signed-off-by: Sarveshwar Bandi <Sarveshwar.Bandi@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When operating in a mode that initiates communication and using HT40 we should fail if we cannot use both primary and secondary channels to initiate communication. Our current ht40 allowmap only covers STA mode of operation, for beaconing modes we need a check on the fly as the mode of operation is dynamic and there other flags other than disable which we should read to check if we can initiate communication. Do not allow for initiating communication if our secondary HT40 channel has is either disabled, has a passive scan flag, a no-ibss flag or is a radar channel. Userspace now has similar checks but this is also needed in-kernel. Reported-by: Jouni Malinen <jouni.malinen@atheros.com> Cc: stable@kernel.org Signed-off-by: Luis R.

| * | ipv6: addrconf: don't remove address state on ifdown if the address is being ↵Lorenzo Colitti2010-11-121-16/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kept Currently, addrconf_ifdown does not delete statically configured IPv6 addresses when the interface is brought down. The intent is that when the interface comes back up the address will be usable again. However, this doesn't actually work, because the system stops listening on the corresponding solicited-node multicast address, so the address cannot respond to neighbor solicitations and thus receive traffic. Also, the code notifies the rest of the system that the address is being deleted (e.g, RTM_DELADDR), even though it is not. Fix it so that none of this state is updated if the address is being kept on the interface. Tested: Added a statically configured IPv6 address to an interface, started ping, brought link down, brought link up again. When link came up ping kept on going and "ip -6 maddr" showed that the host was still subscribed to there Signed-off-by: Lorenzo Colitti <lorenzo@google.com> Signed-off-by: David S.

Just skip this new code block if sock_owned_by_user() is true and eliminate the now superfluous sock_owned_by_user() code block contained within.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now with improved comma support. On parsing malformed X.25 facilities, decrementing the remaining length may cause it to underflow. Since the length is an unsigned integer, this will result in the loop continuing until the kernel crashes. This patch adds checks to ensure decrementing the remaining length does not cause it to wrap around. Signed-off-by: Dan Rosenberg <drosenberg@vsecurity.com> Signed-off-by: David S.

| * | ixgbe: Look inside vlan when determining offload protocol.Hao Zheng2010-11-121-28/+32

However, if vlan offloading is disabled or otherwise not used, the protocol field will be ETH_P_8021Q, not the actual protocol. This will cause the offloading to be not performed correctly, even though the hardware is capable of looking inside vlan tags. Instead, look inside the header if necessary to determine the correct protocol type. To some extent this fixes a regression from 2.6.36 because it was previously not possible to disable vlan offloading and this error case was not exposed.
