veth: Enforce minimum size of VETH_INFO_PEER

2012-02-15T19:59:20+00:00

VETH_INFO_PEER carries struct ifinfomsg plus optional IFLA
attributes. A minimal size of sizeof(struct ifinfomsg) must be
enforced or we may risk accessing that struct beyond the limits
of the netlink message.

Sweep away N/A fw_version dustbunnies from the .get_drvinfo routine of a number of drivers

2011-11-22T21:43:32+00:00

Per discussion with Ben Hutchings and David Miller, go through and
remove assignments of "N/A" to fw_version in various drivers'
.get_drvinfo routines.  While there clean-up some use of bare
constants and such.

net: remove NETIF_F_NO_CSUM feature bit

2011-11-16T22:43:12+00:00

Only distinct use is checking if NETIF_F_NOCACHE_COPY should be
enabled by default. The check heuristics is altered a bit here,
so it hits other people than before. The default shouldn't be
trusted for performance-critical cases anyway.

For all other uses NETIF_F_NO_CSUM is equivalent to NETIF_F_HW_CSUM.

net: sweep-up some straglers in strlcpy conversion of .get_drvinfo routines

2011-11-16T22:38:55+00:00

Convert some remaining straglers' .get_drvinfo routines to use strlcpy
rather than strcpy/strncpy.

net: better pcpu data alignment

2011-11-08T20:10:59+00:00

Tunnels can force an alignment of their percpu data to reduce number of
cache lines used in fast path, or read in .ndo_get_stats()

percpu_alloc() is a very fine grained allocator, so any small hole will
be used anyway.

drivers/net: Add module.h to drivers who were implicitly using it

2011-10-31T23:31:07+00:00

The device.h header was including module.h, making it present for
most of these drivers.  But we want to clean that up.  Call out the
include of module.h in the modular network drivers.

net: Audit drivers to identify those needing IFF_TX_SKB_SHARING cleared

2011-07-28T05:39:30+00:00

After the last patch, We are left in a state in which only drivers calling
ether_setup have IFF_TX_SKB_SHARING set (we assume that drivers touching real
hardware call ether_setup for their net_devices and don't hold any state in
their skbs.  There are a handful of drivers that violate this assumption of
course, and need to be fixed up.  This patch identifies those drivers, and marks
them as not being able to support the safe transmission of skbs by clearning the
IFF_TX_SKB_SHARING flag in priv_flags

Exclude duplicated checking for iface-up. This flags is checked in 'is_skb_forwardable' function, which is subroutine of 'dev_forward_skb'.
