| | | | | | | | | struct ucred; struct process then directly links to the ucred Based on a discussion at c2k10 or so before noting that FreeBSD and NetBSD did this too. ok matthew@

* Changing the socket buffer flags sb_flags was not interrupt safebluhm2013-01-151-3/+3
| | | | | | | | as |= and &= are non-atomic operations. To avoid additional locks, put the flags that have to be accessed from interrupt into a separate sb_flagsintr 32 bit integer field. sb_flagsintr is protected by splsoftnet. Input from miod@ deraadt@; OK deraadt@

| | | | | | and should return stat information instead of EINVAL from deep in the guts of tcp_usrreq. While there, put some more information into struct stat, inspired by FreeBSD. EINVAL problem reported in PR 5943

| | | | | | | | | | | | | get hung in nfs_reconnect() because they do not have the proper privilages to bind to a socket, by adding a struct proc * argument to sobind() (and the *_usrreq() routines, and finally in{6}_pcbbind) and do the sobind() with proc0 in nfs_connect. OK markus@, blambert@. "go ahead" deraadt@. Fixes an issue reported by bernd@ (Tested by bernd@). Fixes PR5135 too.
* exclude control data from the number of bytes returned by FIONREAD ioctl()kurt2007-02-261-2/+2

* Replace select backends with poll backends. selscan() and pollscan()millert2003-09-231-33/+28
| | | | | | | now call the poll backend. With this change we implement greater poll(2) functionality instead of emulating it via the select backend. Adapted from NetBSD and including some changes from FreeBSD. Tested by many, deraadt@ OK
