forcedeth: Improve stats counters · 0bdfea8b

由 Mandeep Baines 提交于 11月 05, 2011

Rx byte count was off; instead use the hardware's count.  Tx packet
count was counting pre-TSO packets; instead count on-the-wire packets.
Report hardware dropped frame count as rx_fifo_errors.

- The count of transmitted packets reported by the forcedeth driver
  reports pre-TSO (TCP Segmentation Offload) packet counts and not the
  count of the number of packets sent on the wire. This change fixes
  the forcedeth driver to report the correct count. Fixed the code by
  copying the count stored in the NIC H/W to the value reported by the
  driver.

- Count rx_drop_frame errors as rx_fifo_errors:
  We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
  for too long.  Normally, rx_fifo_errors would be counted in this case.
  The rx_drop_frame error count is private to forcedeth and is not
  reported by ifconfig or sysfs.  The rx_fifo_errors count is currently
  unused in the forcedeth driver.  It is reported by ifconfig as overruns.
  This change reports rx_drop_frame errors as rx_fifo_errors.

forcedeth: remove unneeded stats updates · 4687f3f3

由 david decotigny 提交于 11月 05, 2011

Function ndo_get_stats() updates most of the stats from hardware
registers, making the manual updates un-needed. This change removes
these manual updates. Main exception is rx_missed_errors which needs
manual update.

Another exception is rx_packets, still updated manually in this commit
to make sure this patch doesn't change behavior of driver. This will
be addressed by a future patch.

forcedeth: fix race when unloading module · f9c4082d

由 david decotigny 提交于 11月 05, 2011

When forcedeth module is unloaded, there exists a path that can lead
to mod_timer() after del_timer_sync(), causing an oops. This patch
short-circuits this unneeded path, which originates in
nv_get_ethtool_stats().

Tested:
  x86_64 16-way + 3 ethtool -S infinite loops + 100Mbps incoming traffic
  + rmmod/modprobe/ifconfig in a loop

sky2: fix regression on Yukon Optima · 27d240fd

由 stephen hemminger 提交于 11月 04, 2011

Changes to support other Optima types, introduced an accidental
regression that caused 88E8059 to come up in 10Mbit/sec.

The Yukon Optima supports a reverse auto-negotiation feature that
was incorrectly setup, and not needed. The feature could be used to
allow wake-on-lan at higher speeds. But doing it correctly would require
other changes to initialization.

netlink: validate NLA_MSECS length · c30bc947

由 Johannes Berg 提交于 11月 03, 2011

L2TP for example uses NLA_MSECS like this:
policy:
        [L2TP_ATTR_RECV_TIMEOUT]        = { .type = NLA_MSECS, },
code:
        if (info->attrs[L2TP_ATTR_RECV_TIMEOUT])
                cfg.reorder_timeout = nla_get_msecs(info->attrs[L2TP_ATTR_RECV_TIMEOUT]);

As nla_get_msecs() is essentially nla_get_u64() plus the
conversion to a HZ-based value, this will not properly
reject attributes from userspace that aren't long enough
and might overrun the message.

Add NLA_MSECS to the attribute minlen array to check the
size properly.

i825xx and xscale are "sub" Kconfigs to NET_VENDOR_INTEL, so
NET_VENDOR_INTEL should contain ALL the dependencies of the
"sub" Kconfigs.

Same with 8390 is a "sub" Kconfig to NET_VENDOR_NATSEMI, so
NET_VENDOR_NATSEMI needs to contains ALL the dependencies.

Freescale Kconfig only had fs_enet as a sub Kconfig, and already
contained the needed dependencies, just cleaned up the dependencies.

macvlan: receive multicast with local address · 729e72a1

由 stephen hemminger 提交于 11月 02, 2011

When implementing VRRP v2 using macvlan several problems were
discovered.  VRRP is weird in that all routers participating
in a redundant group use the same virtual MAC address.
Macvlan is a natural driver to use for this but it doesn't
work.  The problem is that packets with a macvlan device's
source address are not received.

The problem is actually a regression that date back almost 2 years now.
The original problems started with:

commit 618e1b74
Author: Arnd Bergmann <arnd@arndb.de>
Date:   Thu Nov 26 06:07:10 2009 +0000

    macvlan: implement bridge, VEPA and private mode

This patches restores the original 2.6.32 behavior. Allowing multicast
packets received with the VRRP source address to be received.
