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

Primary site is: http://developer.osdl.org/dev/iproute2 Original FTP site is: ftp://ftp.inr.ac.ru/ip-routing/ How to compile this. -------------------- 1. Look at start of Makefile and set correct values for: KERNEL_INCLUDE should point to correct linux kernel include directory. Default (/usr/src/linux/include) is right as rule. arpd needs to have the db4 development libraries. For debian users this is the package with a name like libdb4.x-dev. DBM_INCLUDE points to the directory with db_185.h which is the include file used by arpd to get to the old format Berkely database routines. Often this is in the db-devel package. 2. make The makefile will automatically build a file Config which contains whether or not ATM is available, etc. 3. To make documentation, cd to doc/ directory , then look at start of Makefile and set correct values for PAGESIZE=a4 , ie: a4 , letter ... (string) PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric) and make there. It assumes, that latex, dvips and psnup are in your path. Stephen Hemminger shemminger@osdl.org Alexey Kuznetsov kuznet@ms2.inr.ac.ru
