Title: 32 character limit in firewall aliases. Can it be increased?
Post by: nyctophilia on July 19, 2021, 12:20:00 am

As this is my very first post:

Hello everyone,
and thanks to the devs for their awesome work!

I have one small question, as I couldn't find any answer by googling. Is there any reason why aliases are limited to 32 characters in total? Could it be increased or will it break code/performance?

We have a use-case which would require more than 32 chars in the alias name, probably double (64) for good measure.

Thank you in advance!

Hi there,

Currently, it's pinned to 32 characters in the OS:

https://github.com/opnsense/src/blob/17a61782d3b8d86464d5bdc38483ee8a0ac6a4f9/sys/netpfil/pf/pf.h#L185

I don't know the implications of increasing it and would hope that FreeBSD pioneers this change if the need is big enough. Feel free to open a ticket here:

https://bugs.freebsd.org/bugzilla/

Kristof will probably respond with a more qualified answer than I can.


Cheers,
Franco
