      ethtool: Fix potential user buffer overflow for ETHTOOL_{G, S}RXFH · bf988435
      由 Ben Hutchings 提交于 
      struct ethtool_rxnfc was originally defined in 2.6.27 for the
ETHTOOL_{G,S}RXFH command with only the cmd, flow_type and data
fields.  It was then extended in 2.6.30 to support various additional
commands.  These commands should have been defined to use a new
structure, but it is too late to change that now.

Since user-space may still be using the old structure definition
for the ETHTOOL_{G,S}RXFH commands, and since they do not need the
additional fields, only copy the originally defined fields to and
from user-space.

Debatable -- the current comment is located at the callsite of
ops->get_sset_count(), which is where an implementor might think to add
a new call.  Not all the numeric fields in ethtool_drvinfo are obtained
from ->get_sset_count().

Hence the "some" in the attached patch to include/linux/ethtool.h,
addressing your comment.

Agreed.

I've attached a follow-up patch, which should enable my/Jeff's kernel
patch to be applied, followed by this one.

      ethtool: Add direct access to ops->get_sset_count · 723b2f57
      由 Jeff Garzik 提交于 
      This patch is an alternative approach for accessing string
counts, vs. the drvinfo indirect approach.  This way the drvinfo
space doesn't run out, and we don't break ABI later.

      ethtool: Add reset operation · d73d3a8c
      由 Ben Hutchings 提交于 
      After updating firmware stored in flash, users may wish to reset the
relevant hardware and start the new firmware immediately.  This should
not be completely automatic as it may be disruptive.

A selective reset may also be useful for debugging or diagnostics.

This adds a separate reset operation which takes flags indicating the
components to be reset.  Drivers are allowed to reset only a subset of
those requested, and must indicate the actual subset.  This allows the
use of generic component masks and some future expansion.
