Function qeth_l2_remove_device invokes qeth_l2_del_all_mc at the end. This is needless, because it is already called in the offline function. And even more this is invalid, because multicast addresses cannot be removed in DOWN state. Thus this patch deletes invocation of qeth_l2_del_all_mc in function qeth_l2_remove_device. Signed-off-by:

This patch serializes device removal and other sysfs-triggered configurations by moving removal of sysfs-attributes to the beginning of the remove functions. And it serializes online/offline setting and discipline-switching (causing reestablishing of the net_device) by making use of a new discipline mutex. Signed-off-by:

This patch fixes a problem that occurs when switching from layer 3 to layer 2 mode. Resetting this mac_bits makes sure that we retrieve our mac address from the card, otherwise the interface simply would'nt work. Signed-off-by:

If the allocations fail in either dwmac1000_setup() or dwmac100_setup() then return NULL. These are called from stmmac_mac_device_setup(). The check for NULL returns in stmmac_mac_device_setup() needed to be moved forward a couple lines. Signed-off-by:

When copying VLAN information to or removing from a slave during slave addition or removal, the bonding code currently holds the bond->lock for write to prevent concurrent modification of the vlan_list / vlgrp. This is unnecessary, as all of these operations occur under RTNL. Holding the bond->lock also caused might_sleep issues for some drivers' ndo_vlan_* functions. This patch removes the extra locking.

After commit ad1afb00 ("vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet)") it is now regular practice for a VLAN "add vid" for VLAN 0 to arrive prior to any VLAN registration or creation of a vlan_group. This patch updates the bonding code that tests for the presence of VLANs configured above bonding. The new logic tests for bond->vlgrp to determine if a registration has occured, instead of testing that bonding's internal vlan_list is empty. The old code would panic when vlan_list was not empty, but vlgrp was still NULL (because only an "add vid" for VLAN 0 had occured). Bonding still adds VLAN 0 to its internal list so that 802.1p frames are handled correctly on transmit when non-VLAN accelerated slaves are members of the bond. The test against bond->vlan_list remains in bond_dev_queue_xmit for this reason. Modification to the bond->vlgrp now occurs under lock (in addition to RTNL), because not all inspections of it occur under RTNL. Additionally, because 8021q will never issue a "kill vid" for VLAN 0, there is now logic in bond_uninit to release any remaining entries from vlan_list. Signed-off-by:

Convert a few calls from kfree_skb to consume_skb Noticed while I was working on dropwatch that I was detecting lots of internal skb drops in several places. While some are legitimate, several were not, freeing skbs that were at the end of their life, rather than being discarded due to an error. This patch converts those calls sites from using kfree_skb to consume_skb, which quiets the in-kernel drop_monitor code from detecting them as drops. Tested successfully by myself Signed-off-by:

Patch to add -EAGAIN error to dropwatch netlink message handling code. -EAGAIN will be returned anytime userspace attempts to transition the state of the drop monitor service to a state that its already in. That allows user space to detect this condition, so it doesn't wait for a success ACK that will never arrive. Tested successfully by me Signed-off-by:

The new netpoll code in bridging contains use-after-free bugs that are non-trivial to fix. This patch fixes this by removing the code that uses skbs after they're freed. As a consequence, this means that we can no longer call bridge from the netpoll path, so this patch also removes the controller function in order to disable netpoll. Signed-off-by:

Even with jumbograms I cannot see any way in which we would need to records a larger than 65535 valued next-header offset. The maximum extension header length is (256 << 3) == 2048. There are only a handful of extension headers specified which we'd even accept (say 5 or 6), therefore the largest next-header offset we'd ever have to contend with is something less than say 16k. Therefore make it a u16 instead of a u32. Signed-off-by: -
