How to increase HFSC_MAX_CLASSES

m1s1u · Sep 30, 2006, 8:25 AM

I was trying to set per IP traffic shaping. I've added around 500 queues and I've got following error on reloading pf rules:

pfctl: DIOCADDALTQ: Cannot allocate memory

Googling about this I've found that the reaseon for this is HFSC_MAX_CLASSES parameter in altq_hfsc.h set by default to 64. To get rid of the error one must set HFSC_MAX_CLASSES to ex. 1024 and recompile the kernel.

Can enyone tell me how to perform abowe operations on pfSense?

you need a freebsd 6.1 full install with all kernel sourches and the gcc compiler and the pfsense kernel options to make a new kernel for pfsense and transfer that to youre pfsense system

Where can I get pfsense kernel options?

The kernel configuration file is:
http://cvs.pfsense.com/cgi-bin/cvsweb.cgi/tools/builder_scripts/conf/pfSense.6?rev=1.33

The patches file is:
http://cvs.pfsense.com/cgi-bin/cvsweb.cgi/tools/builder_scripts/patches.RELENG_6_1?rev=1.10

The patches directory is:
http://cvs.pfsense.com/cgi-bin/cvsweb.cgi/tools/patches/RELENG_6_1/

This is all unsupported. Good luck!

Thanks for the links.

Can you tell me the command to apply the patches to standard freebsd files?

I assume that "patch" command should be used but I'm not sure about the parameters (I've tried some but without success).

Also I'm not sure where should I put *.diff files (I have original freebsd sources in /usr/src)
