net: clear heap allocation for ethtool_get_regs()

2011-02-17T23:14:58+00:00

commit b7c7d01aaed1f71d9afe815a569f0a81465a1744 upstream.

There is a conflict between commit b00916b1 and a77f5db3. This patch resolves
the conflict by clearing the heap allocation in ethtool_get_regs().

ethtool: Add support for vlan accleration.

2010-10-21T08:26:54+00:00

Now that vlan acceleration is handled consistently regardless of usage,
it is possible to enable and disable it at will.  This adds support for
Ethtool operations that change the offloading status for debugging
purposes, similar to other forms of hardware acceleration.

net: clear heap allocations for privileged ethtool actions

2010-10-11T19:23:25+00:00

Several other ethtool functions leave heap uncleared (potentially) by
drivers. Some interfaces appear safe (eeprom, etc), in that the sizes
are well controlled. In some situations (e.g. unchecked error conditions),
the heap will remain unchanged in areas before copying back to userspace.
Note that these are less of an issue since these all require CAP_NET_ADMIN.

net: clear heap allocation for ETHTOOL_GRXCLSRLALL

2010-10-08T17:48:28+00:00

Calling ETHTOOL_GRXCLSRLALL with a large rule_cnt will allocate kernel
heap without clearing it. For the one driver (niu) that implements it,
it will leave the unused portion of heap unchanged and copy the full
contents back to userspace.

ethtool: Allocate register dump buffer with vmalloc()

Some NICs have huge register files which exceed the maximum heap
allocation size.

ethtool, ixgbe: Move RX n-tuple mask fixup to ethtool

2010-09-17T23:53:23+00:00

The ethtool utility does not set masks for flow parameters that are
not specified, so if both value and mask are 0 then this must be
treated as equivalent to a mask with all bits set.  Currently that is
done in the only driver that implements RX n-tuple filtering, ixgbe.
Move it to the ethtool core.

ethtool: change ethtool_set_gro() to use ethtool_op_get_rx_csum

2010-09-17T18:56:18+00:00

To be able to switch on GRO on a device, ethtool_set_gro() checks this
device provides a get_rx_csum() method.

Some devices dont provide this method, while they do support RX
checksumming.

This patch allows bonding to support GRO :

ethtool -K bond0 gro on

ethtool: Remove unimplemented flow specification types

2010-09-15T21:42:13+00:00

struct ethtool_rawip4_spec and struct ethtool_ether_spec are neither
commented nor used by any driver, so remove them.  Adjust padding in
the user-visible unions that included these structures.

Fix references to struct ethtool_rawip4_spec in
ethtool_get_rx_ntuple(), which should use struct ethtool_usrip4_spec.

struct ethtool_usrip4_spec cannot hold IPv6 host addresses and there
is no separate structure that can, so remove ETH_RX_NFC_IP6 and the
reference to it in niu.
