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.

This patch allows the user to create/manage AEAD algorithms with
the ip xfrm command. AEAD algorithms are also known as combined-
mode algorithms. They provide the functionality of encryption
algorithms as well as authentication algorithms.

Hi Stephen:
[IP] xfrm: Allow replay setting
For certain applications there is a requirement to start the
sequence number from a point other than the default. As it
is the kernel provides an interface to do that but it isn't
available through the ip(8) command. Since we're encouraging
people to migrate over to ip(8) for manual keying, it is useful
to have this ability there.
This patch adds support for setting replay sequence numbers
through ip(8).

Some usages of rtnl_send could cause errors (ie flush requests)
others do a listen afterwards.

Fix xfrm state or policy flush message.
And minor updates are included:
o Use static buffer to show unknown value as string.
o Show policy type (ptype) only when kernel specified it.
o Clean-up xfrm_monitor.

o Support policy flag with string format.
Note that kernel defines only one name "localok" for the flag
and it has not had any effect currently.
o Support state flag value XFRM_STATE_NOPMTUDISC.
o Fix to show detailed flags value when "-s" option is used.
o Fix minor typo.

Need to use correct XFRMA_ constants.
Get rid of bogus casts. Fix case where no attribute returned.

Stephen,
Use this patch instead of the one i sent yesterday.
As before, you will need to pull include/linux/xfrm.h from
net-2.6 once Dave applies the kernel patch.
cheers,

[XFRM] see SAD info
i.e instead of something like ip xfrm state ls | grep -i src | wc -l
do:
ip xfrm state count
And you get the count; you can also pass -s to the command line and
get the hash info.

To support Mobile IPv6 RO, the following extension is included:
o Use XFRM_MODE_XXX macro instead of magic number
o New attribute option for all state: source address for
deleting or getting message
o New attribute options for RO: care-of address, last-used timestamp
and wild-receive flag
Note:
Flush command like `ip xfrm state flush` is to remove all XFRM state.
It has been effected for IPsec SAD but with this patch it flushes both
IPsec SAD and Mobile IPv6 RO states.
To make only IPsec SA flush, it is recommanded to specify each XFRM
protocol like below:
`ip x s f proto esp ; ip x s f proto ah ; ip x s f proto comp`

[IPROUTE]: Fix struct alignment with cris architecture
gcc for the cris arch does not pad structures to the next multiple of 4
bytes, as the i386 gcc does.
This causes errors like this when displaying xfrm policies:
# ip x p
!!!Deficit 3, rta_len=300
src 192.168.251.32/29 dst 192.168.251.32/29
dir in priority 0
!!!Deficit 3, rta_len=180
src 0.0.0.0/0 dst 192.168.251.32/29
dir in priority 2208
....
Similar errors are seen from ip x s.
This patch fixes the errors when printing. I'm not sure whether we
should worry about other uses of the affected structs, I've not seen any
other bad effects from this though, so hopefully this is enough.
(Thanks to Herbert Xu for pointing out that NLMSG_SPACE is the correct
macro to use here.)
Tested against 2.6.17.6 kernel on i386, and 2.6.16.1 kernel on cris.

It fixes flush feature for IPsec(ip xfrm).
Jamal gave me comment about it. I've tested it on 2.6.11.7.
Please find the log below, check code and pull it:
bk://bk.skbuff.net:38000/iproute2-xfrm-flush
ChangeSet@1.182, 2005-04-13 21:19:44+09:00, nakam@linux-ipv6.org
[ip] add "deleteall" command for xfrm;
"flush" uses kernel's flush interface and
"deleteall" uses legacy iproute2's flush feature like
getting-and-deleting-for-each.
