Subject: [net-next-2.6 PATCH 0/7] xfrm by MARK

From: Jamal Hadi Salim <hadi@...erus.ca>

Changes since last time:
----------------------
Patch 1/7: Feedback from David Miller; aggregate xfrm_*mark
and correct comment on the type of xfrm_mark

Changes since first time:
----------------------
Patch 1/7: Feedback from Patrick McHardy; We pass to user space any 
mark as long as it has non-zero mask.

This patchset implements manipulation of ipsec tables with the
"mark" tag. You can config the SAD and SPD from user space
with a specified mark. 

Example:
---
#ip xfrm state add src 192.168.2.100 dst 192.168.1.10 proto esp spi 0x00000301 mode tunnel mark 7 auth md5 0x96358c90783bbfa3d7b196ceabe0536b enc des3_ede 0xf6ddb555acfd9d77b03ea3843f2653255afe8eb5573965df

#ip xfrm state get mark 7 src 192.168.2.100 dst 192.168.1.10 proto esp spi 0x00000301
output:
src 192.168.2.100 dst 192.168.1.10
        proto esp spi 0x00000301 reqid 0 mode tunnel
        replay-window 0 
        mark 7/0xffffffff
        auth hmac(md5) 0x96358c90783bbfa3d7b196ceabe0536b
        enc cbc(des3_ede) 0xf6ddb555acfd9d77b03ea3843f2653255afe8eb5573965df
        sel src 0.0.0.0/0 dst 0.0.0.0/0 
#
#
#ip xfrm policy add src 172.16.2.0/24 dst 172.16.1.0/24 \
        dir fwd ptype main \
        tmpl src 192.168.2.100 dst 192.168.1.100 \
        proto esp mode tunnel mark 7 mask 0xffffffff
#
#ip xfrm policy ls
output:
src 172.16.2.0/24 dst 172.16.1.0/24 
        dir fwd priority 0 ptype main 
        mark 7/0xffffffff
        tmpl src 192.168.2.100 dst 192.168.1.100
                proto esp reqid 0 mode tunnel
-----
A mark-configured SAD/SPD entry will use the mark as part of the 
lookup key (both in data and control path).
Example:

---
# ip xfrm pol get src 172.16.2.0/24 dst 172.16.1.0/24 dir fwd
output:
RTNETLINK answers: No such file or directory
# ip xfrm pol get src 172.16.2.0/24 dst 172.16.1.0/24 dir fwd mark 7
output:
src 172.16.2.0/24 dst 172.16.1.0/24 
        dir fwd priority 0 ptype main 
        mark 7/0xffffffff
        tmpl src 192.168.2.100 dst 192.168.1.100
                proto esp reqid 0 mode tunnel
