apparently it works just fine. the number of clones is limited by the v_specbitmap which currently allows for 64 clones total (per system, not per process).
apply the diff and see how all your apps are happily using single device node: /dev/bpf0. thanks to pedro and thib for the spec_open_clone and guenther for helping out big time. i'm not 100% sure we want this but why wouldn't we? generally speaking we also need to move to a single /dev/bpf node, but that can be done, once this diff is tested and we all agree that this is a way to go. so please test and share your thoughts. diff --git sys/sys/conf.h sys/sys/conf.h index b2ee90c..46937fd 100644 --- sys/sys/conf.h +++ sys/sys/conf.h @@ -313,7 +313,7 @@ extern struct cdevsw cdevsw[]; dev_init(c,n,open), dev_init(c,n,close), dev_init(c,n,read), \ dev_init(c,n,write), dev_init(c,n,ioctl), (dev_type_stop((*))) enodev, \ 0, dev_init(c,n,poll), (dev_type_mmap((*))) enodev, \ - 0, 0, dev_init(c,n,kqfilter) } + 0, D_CLONE, dev_init(c,n,kqfilter) } /* open, close, ioctl */ #define cdev_lkm_init(c,n) { \
