A new kernel parameter rsbac_debug_stack has been added, which prints out free stack size at many stages of initialization. I now have final free stack after init of 4-5K instead of 200-300 Bytes. The reason were declarations of huge structs of several KB - well - ... Sorry for that. :( The changed version has just been uploaded as new official 1.1.1 release. Please try it out and report here for next week's first bugfix... ;) Amon. - To unsubscribe from the rsbac list, send a mail to majordomo@rsbac.org with unsubscribe rsbac as single line in the body.
