Preparation for 32 bit table IDs
[IPROUTE]: Preparation for 32 bit table IDs
The route table filter uses an integer for the table number and the value
-1 to represent cloned routes. For 32 bit table IDs it needs to become an
unsigned, so this won't work anymore. Introduce a new filter flag "cloned"
and use instead of filter.tb = -1.

The current behaviour for IPv6 routing table filters is to derive the
table from the route type. This doesn't really work anymore now that IPv6
supports multiple tables. Add detection for IPv6 multiple table support
(relying on the fact that the first routes dumped belong to the local table
and have rtm_table == RT_TABLE_LOCAL with multiple tables) and handle it
like other protocols.
This patch adds a generic netlink controller interface.
The controller is the only module using this at the moment.
Thomas has a sample user of genetlink that would fit here; bug him
for it.

This patch adds ability to monitor tc events similar to ipmonitor.
User runs "tc monitor" (without quotes) and watches events of
addition, deletion and updates from qdiscs, classes, filters and
actions as they happen.

Heres another on top of the others i sent. If you get the time, can
update your git tree with these patches?
If you are planning to make a release soon, please ping me - I have at
least one more patch that i need to work on.
cheers,

Stephen,
I apologize for the last patch I sent not applying cleanly to the latest
iproute2 sources. I realized that this might impede any
review/acceptance of the patch and created a separate patch against the 20060323 build of iproute2, which seems to be the latest (by looking at
the website).
The previous patch wouldn't apply cleanly due to the label of the
ssthresh argument being corrected from REALMS to NUMBER.
Please let us know if there is any other information or assistance we
can be with this patch submission.

The ip(8) command has a bug when dealing with IPoIB link layer
addresses. Specifically it does not correctly handle the addition of
new entries in the neighbor/arp table. For example, this command will
fail:
ip neigh add 192.168.0.138 lladdr
00:00:04:04:fe:80:00:00:00:00:00:00:00:01:73:00:00:00:8a:91 nud
permanent dev ib0
An IPoIB link layer address is 20-bytes (see
http://www.ietf.org/internet-drafts/draft-ietf-ipoib-ip-over-infiniband-09.txt,
section 9.1.1).
The command line parsing code expects link layer addresses to be a
maximum of 16-bytes. Addresses over 16-bytes are truncated.

When assigning an ip address to an ethernet adapter, the newest
(050929) version of 'ip addr' hangs while older versions worked.
The problem was traced to be a removed initialisation. The patch
below corrects this problem.

The symlink commands create absolute symlinks instead of relative.
This causes dangling links in case the package is installed using
DESTDIR. Some package managers will report this as an error.

Hi jamal,
I found some spare time to play around a bit more with you ipt action stuff.
I've tested the patch attached with the testcase here below. It works
fine here. It fixes broken target option checkings (final_check) and a
leak in the merge_options function. I've killed copy_options since I
didn't find any reason why we need it.
--- test.sh ---
tc qdisc del dev wlan0 ingress
tc qdisc add dev wlan0 ingress
tc filter add dev wlan0 parent ffff: protocol ip prio 6 u32 \
match ip src 192.168.0.2/32 flowid 1:16 \
action ipt -j TOS --set-tos Maximize-Reliability
sleep 3
tc -s filter ls dev wlan0 parent ffff:
--- end of test.sh ---
Results:

Now, check if options passed to the target are correct.

missing parameter

btw, how's your schedule ? did you finally get spare time to come to the
netfilter workshop in seville ?
