vpd_data[] is allocated as kmalloc(256, GFP_KERNEL), so if cnt = 255 then (cnt + 3) overflows 256. memset() is executed without checking. vpd_data[cnt+2] must be less than 256-cnt-2 as the latter is number of vpd_data[] elements to copy. Do not fill with zero the beginning of nic->serial_num as it will be filled with vpd_data[]. String in product_name[] should be terminated by '\0'. Signed-off-by:

We assume that "pd" can be null on the previous line, and throughout the function so we should check it here as well. This was introduced by 9b2c2ff7 "mv643xx_eth: use sw csum for big packets" Signed-off-by:

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:

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:

After the change from mdio polling to irq, it became necessary to restore the interrupt mask after resetting the chip in fec_stop(). Otherwise, with all irqs disabled, no communication with the PHY will be possible after e.g. un-/replugging the cable and the device gets stalled. Signed-off-by:
