kernel 2.4.18 and RH 7.2

kernel 2.4.18 and RH 7.2

[Joe]

Not sure if this has been reported as I am not on the mailing list.  I'm
guessing probably yes.

I have a RH 7.2 box and am getting the following error from iptables and
kernel 2.4.18. I don't get it in 2.4.17.

output from /etc/init.d/iptables start

I'll add a "me too" to this - 2.4.18, iptables 1.2.4

Setting up IPv4 mangle rules:
iptables: libiptc/libip4tc.c:384: do_check: Assertion `h->info.valid_hooks == (1 << 0 | 1 << 3)' failed.
/etc/fw-ipv4/mangle: line 2:   215 Aborted                 iptables -t mangle -F
iptables: libiptc/libip4tc.c:384: do_check: Assertion `h->info.valid_hooks == (1 << 0 | 1 << 3)' failed.
/etc/fw-ipv4/mangle: line 3:   216 Aborted                 iptables -t mangle -X
iptables: libiptc/libip4tc.c:384: do_check: Assertion `h->info.valid_hooks == (1 << 0 | 1 << 3)' failed.
/etc/fw-ipv4/mangle: line 15:   217 Aborted                 iptables -t mangle -A PREROUTING -i eth0 -d xxx.xxx.xxx.xxx/xx -j ACCEPT
... lots more ...

The rules do appear to be in the kernel however.

iptables 1.2.4 was rebuild for the 2.4.17 because it stopped working at
that point.  I hope it isn't requirement to rebuild iptables against each
stable kernel release.

Its not a requirement for 1.2.4 and 2.4.18 either - what happened was that
some people (Red Hat notably) turned all the paranoid debugging stuff on
and that is what spews the warnings.

[Joe]

Unfortunately it is not just warnings.  It does not allow the firewall /
packet filter to start and iptables -L shows an open system as the rules were
never applied.  Needless to say I'm back on 2.4.17.

Maybe I should file this as a bug with RH 7.2 then......

Please try  1.2.6 snapshot or try rebuild it with -DNODEBUG make flag.
