* Keep socket timeout intervals in nsecs and use them with tsleep_nsec(9).mpi2020-01-151-3/+3
| | | | | | | | | | | | | | Introduce and use TIMEVAL_TO_NSEC() to convert SO_RCVTIMEO/SO_SNDTIMEO specified values into nanoseconds. As a side effect it is now possible to specify a timeout larger that (USHRT_MAX / 100) seconds. To keep code simple `so_linger' now represents a number of seconds with 0 meaning no timeout or 'infinity'. Yes, the 0 -> INFSLP API change makes conversions complicated as many timeout holders are still memset()'d. Inputs from cheloha@ and bluhm@, ok bluhm@

* Remove useless splsoftnet().mpi2017-05-171-11/+3
| | | | | | | | | | Outside of USB, no code is executed in a softnet interrupt context. So what's protecting NFS data structures is the KERNEL_LOCK(). But more importantly, since r1.114 of nfs_socket.c, the 'softnet' thread is no longer executing NFS code. ok visa@

* all pools have their ipl set via pool_setipl, so fold it into pool_init.dlg2016-09-151-3/+2
| | | | | | | | | | | | | | | | | | | | | | the ioff argument to pool_init() is unused and has been for many years, so this replaces it with an ipl argument. because the ipl will be set on init we no longer need pool_setipl. most of these changes have been done with coccinelle using the spatch below. cocci sucks at formatting code though, so i fixed that by hand. the manpage and subr_pool.c bits i did myself. ok tedu@ jmatthew@ @ipl@ expression pp; expression ipl; expression s, a, o, f, m, p; @@ -pool_init(pp, s, a, o, f, m, p); -pool_setipl(pp, ipl); +pool_init(pp, s, a, ipl, f, m, p);

* Store a unique ID, an interface index, rather than a pointer to thempi2015-06-161-2/+2
| | | | | | | | | | | | | | | receiving interface in the packet header of every mbuf. The interface pointer should now be retrieved when necessary with if_get(). If a NULL pointer is returned by if_get(), the interface has probably been destroy/removed and the mbuf should be freed. Such mechanism will simplify garbage collection of mbufs and limit problems with dangling ifp pointers. Tested by jmatthew@ and krw@, discussed with many. ok mikeb@, bluhm@, dlg@

| | | | | | | | | | | | | | | | each mount, and when work is "found", peg an aiod to that mount todo the I/O. Make nfs_asyncio() a bit smarter when deciding when to do asyncio and when to force it sync, this is done by keeping the aiod's one two lists, an "idle" and an "all" list, so asyncio is only done when there are aiods hanging around todo it for us or are already pegged to the mount. Idea liked by at least beck@ (and I think art@). Extensive testing done by myself and jasper and a few others on various arch's. Ideas/Code from Net/Free. OK blambert@.
