2015-02-20openvswitch: Fix net exit.Pravin B Shelar
Open vSwitch allows moving internal vport to different namespace while still connected to the bridge. But when namespace deleted OVS does not detach these vports, that results in dangling pointer to netdevice which causes kernel panic as follows. This issue is fixed by detaching all ovs ports from the deleted namespace at net-exit. BUG: unable to handle kernel NULL pointer dereference at 0000000000000028 IP: [<ffffffffa0aadaa5>] ovs_vport_locate+0x35/0x80 [openvswitch] Oops: 0000 [#1] SMP Call Trace: [<ffffffffa0aa6391>] lookup_vport+0x21/0xd0 [openvswitch] [<ffffffffa0aa65f9>] ovs_vport_cmd_get+0x59/0xf0 [openvswitch] [<ffffffff8167e07c>] genl_family_rcv_msg+0x1bc/0x3e0 [<ffffffff8167e319>] genl_rcv_msg+0x79/0xc0 [<ffffffff8167d919>] netlink_rcv_skb+0xb9/0xe0 [<ffffffff8167deac>] genl_rcv+0x2c/0x40 [<ffffffff8167cffd>] netlink_unicast+0x12d/0x1c0 [<ffffffff8167d3da>] netlink_sendmsg+0x34a/0x6b0 [<ffffffff8162e140>] sock_sendmsg+0xa0/0xe0 [<ffffffff8162e5e8>] ___sys_sendmsg+0x408/0x420 [<ffffffff8162f541>] __sys_sendmsg+0x51/0x90 [<ffffffff8162f592>] SyS_sendmsg+0x12/0x20 [<ffffffff81764ee9>] system_call_fastpath+0x12/0x17 Reported-by: Assaf Muller <amuller@redhat.com> Fixes: 46df7b81454("openvswitch: Add support for network namespaces.")

2015-02-20net: phy: Fix verification of EEE support in phy_init_eeeGuenter Roeck
phy_init_eee uses phy_find_setting(phydev->speed, phydev->duplex) to find a valid entry in the settings array for the given speed and duplex value. For full duplex 1000baseT, this will return the first matching entry, which is the entry for 1000baseKX_Full. If the phy eee does not support 1000baseKX_Full, this entry will not match, causing phy_init_eee to fail for no good reason.

2015-02-20be2net: Refactor be_xmit_enqueue() routineSriharsha Basavapatna
- Reduce code duplication by moving WRB-frags setup into a function. - Do not setup WRB-header before frags are setup, which is unncessary if there's errors while setting up frags. We should only grab an entry for the header, setup the frags and if everything is fine setup the header. - The error cleanup can be moved into a small function.

2015-02-20be2net: Refactor wrb_fill_hdr() routineSriharsha Basavapatna
The WRB header is setup by wrb_fill_hdr() routine. This routine currently gets some of the WRB params as args and figures out rest of the WRB params by looking at various fields in skb (like gso, checksum, vlan-tag etc). All these params could instead be retrieved from the skb into a structure and passed to this routine. This separates wrb_fill_hdr() to only provide chip-specific code to fill the WRB. This also makes it simple to support chips with different WRB formats. Signed-off-by: Sriharsha Basavapatna <sriharsha.basavapatna@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-02-20Bluetooth: Remove unnecessary queue_monitor_skb() functionJohan Hedberg
Now that there's the general purpose hci_send_to_channel() API it will do the exact same thing as queue_monitor_skb() when passed the monitor HCI channel.

2015-02-20Bluetooth: Rename hci_send_to_control to hci_send_to_channelJohan Hedberg

2015-02-20Bluetooth: Use hci_copy_identity_addr() helper for SMP chan creationJohan Hedberg
The only reason the SMP code is essentially duplicating the hci_copy_identity_addr() function is that the helper returns the address type in the HCI format rather than the three-value format expected by l2cap_chan. This patch converts the SMP code to use the helper and then do a simple conversion from one address type to another.

Since commit 8e5cfb55d3f (Btrfs: Make raid_map array be inlined in btrfs_bio structure), the raid map array is allocated along with the btrfs bio in alloc_btrfs_bio. The calculation used to decide how much we need to allocate was using the wrong parameter passed into the allocation function. The passed in real_stripes will be zero if a target replace operation is not currently running. We want to use total_stripes instead.
