When the source address of a tunnel is given as 0.0.0.0 do a routing lookup
to get the real source address for the destination and fill that into the
acquire message. This allows to specify policies like this:
spdadd 172.16.128.13/32 172.16.0.0/20 any -P out ipsec
esp/tunnel/0.0.0.0-x.x.x.x/require;

On PowerPC, we want to be able to provide an AT_PLATFORM aux table
entry to userspace, so that glibc can choose optimized libraries for
the processor we're running on. Unfortunately that would be the 21st
aux table entry on powerpc, meaning that the aux table including the
terminating null entry would overflow the mm->saved_auxv[] array,
leading to userland programs segfaulting.
This increases the size of the mm->saved_auxv array to be large enough
to accommodate an AT_PLATFORM entry on powerpc.

This monster-patch tries to do the best job for unifying the data
structures and backend interfaces for the three evil clones ip_tables,
ip6_tables and arp_tables. In an ideal world we would never have
allowed this kind of copy+paste programming... but well, our world
isn't (yet?) ideal.
o introduce a new x_tables module
o {ip,arp,ip6}_tables depend on this x_tables module
o registration functions for tables, matches and targets are only
wrappers around x_tables provided functions
o all matches/targets that are used from ip_tables and ip6_tables
are now implemented as xt_FOOBAR.c files and provide module aliases
to ipt_FOOBAR and ip6t_FOOBAR
o header files for xt_matches are in include/linux/netfilter/,
include/linux/netfilter_{ipv4,ipv6} contains compatibility wrappers
around the xt_FOOBAR.h headers
Based on this patchset we're going to further unify the code,
gradually getting rid of all the layer 3 specific assumptions.

At least some versions of the via-velocity hardware only support
checksumming IPv4 frames in hardware. However, the driver is currently
setting the NETIF_F_HW_CSUM flag, which indicates support for more than
just IPv4. This results in errors when trying to use IPv6 over
via-velocity hardware.

I believe I see the race Michael refers to (tlb_choose_channel
may set head, which tlb_init_slave clears), although I was not able to
reproduce it. I have updated his patch for the current netdev-2.6.git
tree and added a version update. His original comment follows:
Our systems have been crashing during testing of PCI HotPlug
support in the various networking components. We've faulted in
the bonding driver due to a bug in bond_alb.c:tlb_clear_slave()
In that routine, the last modification to the TLB hash table is
made without protection of the lock, allowing a race that can lead
tlb_choose_channel() to select an invalid table element.

This patch allows the Atmel driver to work correctly with wpa_supplicant
and other programs that require some conformance with WEXT-18. It
should not affect current behavior of the driver. The patch does four
things:
1) Implements SIOCSIWENCODEEXT, SIOCGIWENCODEEXT, SIOCSIWAUTH, and
SIOCGIWAUTH calls for unencrypted and WEP operation
2) Accepts zero-filled addresses for SIOCSIWAP, which are legal and
should turn off any previous forced WAP address
3) Sends association and de-association events to userspace at most of
the appropriate times
4) Fixes erroneous order of CIPHER_SUITE_WEP_* arguments in one location
which are actually unused anyway

We have identified two related bugs in the e100 driver.
Both bugs are related to manipulation of the MDI control register.
The first problem is that the Ready bit is being ignored when writing to
the Control register; we noticed this because the Linux bonding driver
would occasionally come to the spurious conclusion that the link was down
when querying Link State. It turned out that by failing to wait for a
previous command to complete it was selecting what was essentially a random
register in the MDI register set. When we added code that waits for the
Ready bit (as shown in the patch file below) all such problems ceased.
The second problem is that, although access to the MDI registers involves
multiple steps which must not be intermixed, nothing was defending against
two or more threads attempting simultaneous access. The most obvious
situation where such interference could occur involves the watchdog versus
ioctl paths, but there are probably others, so we recommend the locking
shown in our patch file.
