I have shorewall 4.6.1.2 (Debian package version 4.6.1.2-1).
I am trying to set mark with "|" and "&" in the tcrules file, and
it doesn't work.
The relevant lines in tcrules look ilke this:
# "OR" 0x40 into flags for packets to or from address 10.1.2.3,
# provided the connection mark is zero.
|0x40:P 10.1.2.3 0.0.0.0/0 - { test=0:C }
|0x40:T 0.0.0.0/0 10.1.2.3 - { test=0:C }
The relevant lines in the output from /sbin/shorewall trace safe-restart
look like this:
Compiling /etc/shorewall/tcrules...
IN===> |0x40:P 10.1.2.3 0.0.0.0/0 - { test=0:C }
NF-(A)-> mangle:tcpre:1 -A tcpre -s 10.1.2.3 -m
connmark --mark 0/0xff -j MARK --set-mark 0x40
IN===> |0x40:T 0.0.0.0/0 10.1.2.3 - { test=0:C }

connmark --mark 0/0xff -j MARK --set-mark 0x40
WARNING: Non-empty tcrules file (/etc/shorewall/tcrules); consider running

See it using "--set-mark" instead of "--or-mark". Also, the
message suggests that the tcrules file is deprecated, but the
shorewall-tcrules man page does not appear to say it's deprecated.
I think this is a bug, and line 560 of Shorewall/Tc.pm look
suspicious:
handle_mark_param('--set-mark' , , HIGHMARK );
handle_mark_param seems to expect the first argument to be false
in the case that AND and OR handling is desired.
