Subject: [LARTC] u32 hashing filter - deletion problem!
Date: Wed, 12 Oct 2005 22:17:01 +0000	[thread overview]
Message-ID: <20051013001701.5a00d79c@cat> (raw)

Hi there,

I'm having a bit of a headache because of the u32 filter with hashing... My router administration system updates filter configuration differentially. Therefore I need to delete filters sometimes. I know that by deleting root class I'd make all filters go away, but I can't use that option in this particular case.

When I delete even a single u32 hashed filter I end up with non-functional u32 hashed filters. No band is classified by hashed u32 filters any more. The only thing that saves the day is a root class delete and full filter reload.

Test platform 1
---------------
tested kernels: 2.6.13.4 and 2.6.11-rc4 (both with SMP)
Hardware: 	2 x Intel(R) Xeon(TM) CPU 2.40GHz with HT enabled

Test platform 2
---------------
tested kernels: 2.6.13.2
Hardware:	AMD Athlon 900MHz

I don't know if it's important, but I'm using CPU cycle counter as a packet scheduler clock source on both systems.

Any comments? Should I go to the kernel dev group with this?

Cheers,
Marek Kierdelewicz
