Both mega flow mask's reference counter and per flow table mask list should only be accessed when holding ovs_mutex() lock. However this is not true with ovs_flow_table_flush(). The patch fixes this bug. Reported-by:

While the zerocopy method is correctly omitted if user space does not support unaligned Netlink messages. The attribute is still not padded correctly as skb_zerocopy() will not ensure padding and the attribute size is no longer pre calculated though nla_reserve() which ensured padding previously. This patch applies appropriate padding if a linear data copy was performed in skb_zerocopy(). Signed-off-by:

Backend drivers shouldn't transistion to CLOSED unless the frontend is CLOSED. If a backend does transition to CLOSED too soon then the frontend may not see the CLOSING state and will not properly shutdown. So, treat an unexpected backend CLOSED state the same as CLOSING. Signed-off-by:

When configuring GRE tunnel using OVS, tcp stream is distributed over all RSS queues which may cause TCP reordering. It happens since OVS uses L2GRE protocol when kernel gre uses IPGRE. Patch defaults gre tunnel to L2GRE which allows proper RSS for L2GRE packets and (implicitly) disables RSS for IPGRE traffic. Signed-off-by:

MII management bus clock is derived from the MAC clock by dividing it by MIIMODER register CLKDIV field value. This value may need to be set up in case it is undefined or its default value is too high (and communication with PHY is too slow) or too low (and communication with PHY is impossible). The value of CLKDIV is not specified directly, but is derived from the MAC clock for the default MII management bus frequency of 2.5MHz. The MAC clock may be specified in the platform data, or in the 'clocks' device tree attribute. Signed-off-by:

OpenCores 10/100 Mbps MAC does not support speeds above 100 Mbps, but does not disable advertisement when PHY supports them. This results in non-functioning network when the MAC is connected to a gigabit PHY connected to a gigabit switch. The fix is to disable gigabit speed advertisement on attached PHY unconditionally.

When a Gigabit PHY device is connected to a 10/100Mbits capable Ethernet MAC, the driver will restrict the phydev->supported modes to mask off Gigabit. If the Gigabit PHY comes out of reset with the Gigabit features set by default in MII_CTRL1000, it will keep advertising these feature, so by the time we call genphy_config_advert(), the condition on phydev->supported having the Gigabit features on is false, and we do not update MII_CTRL1000 with updated values, and we keep advertising Gigabit features, eventually configuring the PHY for Gigabit whilst the Ethernet MAC does not support that. This patches fixes the problem by ensuring that the Gigabit feature bits are always cleared in MII_CTRL1000, if the PHY happens to be a Gigabit PHY, and then, if Gigabit features are supported, setting those and updating MII_CTRL1000 accordingly.

Ding Tianhong says: ==================== bonding: Fix some issues for fail_over_mac The parameter fail_over_mac only affect active-backup mode, if it was set to active or follow and works with other modes, just like RR or XOR mode, the bonding could not set all slaves to the master's address, it will cause the slave could not work well with master. v1->v2: According Jay's suggestion, that we should permit setting an option at any time, but only have it take effect in active-backup mode, so I add mode checking together with fail_over_mac during enslavement and rebuild the patches. v2->v3: The correct way to fix the problem is that we should not add restrictions when setting options, just need to modify the bond enslave and removal processing to check the mode in addition to fail_over_mac when setting a slave's MAC during enslavement. The change active slave processing already only calls the fail_over_mac function when in active-backup mode.

The fail_over_mac could be set to active or follow in any time for all modes, so if the fail_over_mac is not none and the current mode is not active-backup, the bond_set_mac_address() could not change the master and slave's MAC address. In bond_set_mac_address(), the fail_over_mac should only affect AB mode, so modify to check the mode in addition to fail_over_mac when setting bond's MAC address.

According to bonding.txt, the fail_over_ma should only affect active-backup mode, but I found that the fail_over_mac could be set to active or follow in all modes, this will cause new slave could not be set to bond's MAC address at enslave processing and restore its own MAC address at removal processing. The correct way to fix the problem is that we should not add restrictions when setting options, just need to modify the bond enslave and removal processing to check the mode in addition to fail_over_mac when setting a slave's MAC during enslavement. The change active slave processing already only calls the fail_over_mac function when in active-backup mode. Thanks for Jay's suggestion. The patch also modify the pr_warning() to pr_warn().

Setting rt variable to NULL at the beginning of ip_tunnel_xmit() missed possible use of this variable as a scratch value. Also fixes a possible dst leak in tunnel_dst_check() : If we had to call tunnel_dst_reset(), we forgot to release the reference on dst. Merges tunnel_dst_get()/tunnel_dst_check() into a single tunnel_rtable_get() function for clarity. Many thanks to Tommi for his report and tests.

Self generated skbuffs in net/can/bcm.c are setting a skb->sk reference but no explicit destructor which is enforced since Linux 3.11 with commit 376c7311 (net: add a temporary sanity check in skb_orphan()). This patch adds some helper functions to make sure that a destructor is properly defined when a sock reference is assigned to a CAN related skb. To create an unshared skb owned by the original sock a common helper function has been introduced to replace open coded functions to create CAN echo skbs. Signed-off-by:

Chris Mason reported a NULL pointer derefernence in generic_getxattr() that was due to sb->s_xattr being NULL. The reason is that the nfs #ifdef's for ACL support were misplaced, and the nfs3 inode operations had the xattr operation pointers set up, even though xattrs were not actually supported. As a result, the xattr code was being called without the infrastructure having been set up. Move the #ifdef's appropriately. Reported-and-tested-by:
