I've released a new zero copy sockets snapshot, based on -current from June 20th, 2002. http://people.FreeBSD.org/~ken/zero_copy This fixes the following issues: - Use SLIST_FIRST() macros to access the first entry in a SLIST in uipc_jumbo.c. I didn't fix all of these when Alfred pointed out the problem. (Pointed out by Bosko Milekic.) - Remove superfluous TI_LOCK()/TI_UNLOCK() calls in the zero copy version of ti_newbuf_jumbo(). We already have the lock in all the places ti_newbuf_jumbo() is called. (Prompted by Bosko Milekic.) - In the SIOCGIFMEDIA ioctl in ifmedia_ioctl(), avoid calling malloc() with M_WAITOK. Return an error if the M_NOWAIT malloc fails. The ti(4) driver and the wi(4) driver, at least, call this with a mutex held. This causes witness warnings for 'ifconfig -a' with a wi(4) or ti(4) board in the system. (I've only verified for ti(4)). Feedback and comments are welcome!
