Reported by: Satoru SATOH <satoru.satoh@gmail.com>
"ip route show" does not print correct value when larger rto_min is
set (e.g. 3sec).

This problem is because of overflow in print_route() and
the patch below is a workaround fix for that.

[root test]# ./iproute2.git.org/ip/ip route show dev eth1
192.168.140.0/24  proto kernel  scope link  src 192.168.140.130
169.254.0.0/16  scope link
[root test]# ./iproute2.git.org/ip/ip route change 192.168.140.0/24
dev eth1 rto_min 3s
[root test]# ./iproute2.git.org/ip/ip route show dev eth1
192.168.140.0/24  scope link  rto_min lock 2ms     <-- wrong
169.254.0.0/16  scope link
[root test]# ./iproute2.git/ip/ip route show dev eth1  # patched version
192.168.140.0/24  scope link  rto_min lock 3000ms  <-- correct
169.254.0.0/16  scope link

This is a simpler fix.

Updated patch, added your netmask validation code but without the check
that made 0.0.0.0 (default) and 255.255.255.255 (one address) invalid
netmasks as they are permitted in CIDR format.

Hello Stephen,

As the current maintainer of iproute2 package, you could be interested
in including the attached patch that allow using masks in the fw filter
of the tc utility (very useful at least for me). AFAK, it works at least
from iproute2 version 2.6.20-?. Feel free to make the appropriate
cleaning changes if necessary, or contact me if you see any trouble.

Best regards,
François Delawarde.

The ip util would happily change these flags, it's just not recommended.
Reflect that in the doc.

The behaviour of ifconfig is exactly the same as of ip, delete the note about
it.

It seems it fails to properly detect that your kernel is missing
RTM_NEWLINK support. Apparently the reason is that the kernels

Follow up patch to "Fix overflow in time2tick / tick2time." which switches
the remaining two helper functions from long to unsigned as well.
These functions are only used in "tc/q_hfsc.c" where both the passed argument
and the place the return value is stored are unsigned/u32 variables, so this
change should be safe to make but hasn't been tested as extensively as the
time2tick patch.

The help/usage screen of ematch cmp and nbyte say recognised symbolic
values for "layer FOO" are link, header and next-header, but the code
does _not_ implement that: it will recognise "next-header" as what is
supposed to be "header" and will not recognise "header". The right
symbolic values seem to be link, network, transport. Here is a patch
that changes the help/usage screen to match the code.
