Description Cassiano Martin 2013-10-24 13:08:42 UTC 
ebtables fails add or list any kernel rules. it prints the following message:

"The kernel doesn't support the ebtables filter table."


I've had to add the following cflags to the build process: -DEBT_MIN_ALIGN=8 -DKERNEL_64_USERSPACE_32

This fixes when building a 32 bit userland and a 64 bit kernel on mips64 platform. 

Thanks
Comment 1 Gustavo Zacarias 2013-10-24 17:18:31 UTC 
Can you test if -DKERNEL64_USERSPACE_32 is enough?
-DEBT_MIN_ALIGN=8 is used/meant for sparc64 which doesn't handle unaligned memory accesses.
Regards.
Comment 2 Cassiano Martin 2013-10-25 12:28:31 UTC 
Yes, you are right. -DKERNEL_64_USERSPACE_32 is enough. Tested on my board and it worked.

Thanks
