The iproute package keeps its own headers so there is no need
of polluting code with #ifdef's

Hi,

here is a patch against iproute2 to allow user to set a state with a specific
auth length.

Example:
$ ip xfrm state add src 10.16.0.72 dst 10.16.0.121 proto ah spi 0x10000000
auth-trunc "sha256" "azertyuiopqsdfghjklmwxcvbn123456" 96 mode tunnel
$ ip xfrm state
src 10.16.0.72 dst 10.16.0.121
         proto ah spi 0x10000000 reqid 0 mode tunnel
         replay-window 0
         auth-trunc hmac(sha256)
0x617a6572747975696f707173646667686a6b6c6d77786376626e313233343536 96
         sel src 0.0.0.0/0 dst 0.0.0.0/0

Regards,
Nicolas

Subject: [PATCH] iproute2: allow to specify truncation bits on auth algo

Attribute XFRMA_ALG_AUTH_TRUNC can be used to specify
truncation bits, so we add a new algo type: auth-trunc.

In 2.6.39, we can build SFQ queues with a given hash table size,

The get_jiffies() function retrieves rtt-type values in units of
milliseconds. This patch updates the function name accordingly,
following the pattern given by dst_metric() <=> dst_metric_rtt().

Since July 2008 (2.6.27, c1e20f7c8b9), the kernel stores the values for
RTAX_{RTT{,VAR},RTO_MIN} in milliseconds. When using a kernel > 2.6.27 with
the current iproute2, conversion of these values is broken in either way.

This patch
 * updates the code to pass and retrieve milliseconds;
 * since values < 1msec would be rounded up, also drops the usec/nsec variants;
 * since there is no way to query kernel HZ, also drops the jiffies variant.

Arguments such as
	rtt		3.23sec
	rto_min		0xff
	rto_min		0.200s
	rttvar		25ms
now all work as expected when reading back previously set values.

get_jiffies() is in all places called in the same manner, with base=0;
simplify argument list by putting the constant value into the function.

Adds security context support to ip xfrm state.

Adds security context support to ip xfrm policy.
Signed-off-by: Joy Latten <latten@austin.ibm.com>

In the Linux kernel, ipsec policy and SAs can include a
security context to support MAC networking. This feature
is often referred to as "labeled ipsec".

This patchset adds security context support into ip xfrm
such that a security context can be included when
add/delete/display SAs and policies with the ip command.
The user provides the security context when adding
SAs and policies. If a policy or SA contains a security
context, the changes allow the security context to be displayed.

For example,
ip xfrm state
src 10.1.1.6 dst 10.1.1.2
	proto esp spi 0x00000301 reqid 0 mode transport
	replay-window 0
	auth hmac(digest_null) 0x3078
	enc cbc(des3_ede) 0x6970763672656164796c6f676f33646573636263696e3031
	security context root:system_r:unconfined_t:s0

Please  let me know if all is ok with the patchset.
Thanks!!

Add the group keyword to ip link set, which has the following meaning:
If both a group and a device name are pressent, we change the device's
group to the specified one. If only a group is present, then the
operation specified by the rest of the command should apply on an entire
group, not a single device.

So, to set eth0 to the default group, one would use
	ip link set dev eth0 group default

Conversely, to set all the devices in the default group down, use
	ip link set group default down

This reverts commit 632110aa.

There seem to be some recent changes in the 802.1Qbh/bg specs which may
result in changes to this patch in the near future. It seems like its best
to ignore this patch for now.
I will re-spin at a later time when the changes in the specs converge.

BTW, Please let me know if I should CC netdev list and others on the
original email. I can resend this email.

Use sanitized headers from 2.6.37-rc8

In preparation for adding name hash:
  * add const
  * use same types in cache as ifinfomsg
  * rename idxmap to ll_cache

Avoid initializing the LL map (which involves a costly RTNL dump)
multiple times. This can happen when running in batch mode.

The default of 16 is too small for users with 10,000 interfaces.

A small typo fix.

This patch adds save and restore commands to "ip route". Save dumps
the RTNL stream to stdout which can then be passed to restore later.
This may be helpful in some normal situations, and will allow C/R to
migrate the routing information in userspace.  Tweaking of the stream
can be done by userspace helpers to convert between versions and adjust
things like device indexes when restoring routes in a different
environment.

By factoring out some of the common bits of print_route() into
filter_nlmsg(), the "save" command can use the same selection logic
as "list," allowing the caller to save only specific routes as
necessary.

The only change since the RFC is the addition of manpage and doc
material.

Add the iproute2 support for the ACT_CSUM action. Can be used as
following, certainly in conjunction with the ACT_PEDIT action (pedit):

 # In order to DNAT (stateless) IPv4 packet from 192.168.1.100 to
 #  0x12345678 (18.52.86.120), and update the IPv4 header checksum and
 #  the UDP checksum (the last one, only if the packet is UDP).
tc filter add eth0 prio 1 protocol ip parent ffff: \
  u32 match ip src 192.168.1.100/32 flowid :1 \
    action pedit munge offset 16 u32 set 0x12345678 \
      pipe csum ip and udp

 # In order to alter destination address of IPv6 TCP packets from fc00::1
 #  and correct the TCP checksum (nothing happened? except maybe for
 #  checksums in the TCP payload ...).
tc filter add eth0 prio 1 protocol ipv6 parent ffff: \
  u32 match ip6 src fc00::1/128 match ip6 protocol 0x06 0xff flowid :1 \
    action pedit munge offset 24 u32 set 0x12345678 \
      pipe csum tcp

The default remains at 10 for backwards compatibility.

For instance:
 # ip addr flush dev eth2
 *** Flush remains incomplete after 10 rounds. ***
 # ip -l 20 addr flush dev eth2
 *** Flush remains incomplete after 20 rounds. ***
 # ip -loops 0 addr flush dev eth2
 #

This is useful for getting rid of large numbers of IP
addresses in scripts.
