* Initialize va_filerev in vattr_null() to avoid leaking stack garbage;guenther2015-10-131-9/+23
| | | | | | | | | | | | | problem pointed out by Martin Natano (natano (at) natano.net) Also, stop chaining assignments (foo = bar = baz) in vattr_null(). The exact meaning of those depends on the order of the sizes-and- signednesses of the lvalues, making them fragile: a statement here mixed *six* types, but managed to get them in a safe order. Delete a 20+ year old XXX comment that was almost certainly bemoaning a bug from when they were in an unsafe order. ok deraadt@ miod@

This way every consumer of the radix tree has a chance to explicitly initialize the shared data structures and no longer rely on another subsystem to do the initialization. As a bonus ``dom_maxrtkey'' is no longer used an die. ART kernels should now be fully usable because pf(4) and IPSEC properly initialized the radix tree. ok chris@, reyk@

* Stop using a shutdown hook for softraid(4) and explicitly shutdownmpi2014-07-101-1/+9
| | | | | | | | | | | | | | | | | | | the disciplines right after vfs_shutdown(). This change is required in order to be able to set `cold' to 1 before traversing the device (mainbus) tree for DVACT_POWERDOWN when halting a machine. Yes, this is ugly because sr_shutdown() needs to sleep. But at least it is obvious and hopefully somebody will be ofended and fix it. In order to properly flush the cache of the disks under softraid0, sr_shutdown() now propagates DVACT_POWERDOWN for this particular subtree of devices which are not under mainbus. As a side effect sd(4) shutdown hook should no longer be necessary. Tested by stsp@ and Jean-Philippe Ouellet. ok deraadt@, stsp@, jsing@

* While it may be smart to use the radix tree for exports it is not OK toclaudio2014-06-041-28/+28
| | | | | | | | | | use the domain specific tree initialisation method for this since that one is multipath enabled and assumes that the radix node is part of a struct rtentry. This code uses a different struct and so the multipath modifies wrong fields and breaks stuff in mysterious ways. Since we only support AF_INET here anyway simplify the code and only have one radix_node_head pointer instead of AF_MAX ones. Fixes NFS server issues reported by rpe@, OK rpe@, guenther@, sthen@

* Don't map a buffer (and potentially sleep) when invalidating it in vinvalbuf.beck2012-11-171-2/+3
| | | | | | | | | | This fixes a problem where we could sleep for kva and then our pointers would not be valid on the next pass through the loop. We do this by adding buf_acquire_nomap() - which can be used to busy up the buffer without changing its mapped or unmapped state. We do not need to have the buffer mapped to invalidate it, so it is sufficient to acquire it for that. In the case where we write the buffer, we do map the buffer, and potentially sleep.

| | | | | | | | | | | | | | | | | | | vector setup that has questionable features (that have, as far as I can tell never been used in practice, atleast not in OpenBSD), remove all the gunk and favor a simple struct full of function pointers that get set directly by each of the filesystems. Removes gobs of ugly code and makes things simpler by a magnitude. The only downside of this is that we loose the vnoperate feature so the spec/fifo operations of the filesystems need to be kept in sync with specfs and fifofs, this is no big deal as the API it self is pretty static. Many thanks to armani@ who pulled an earlier version of this diff to current after c2k10 and Gabriel Kihlman on tech@ for testing. Liked by many. "come on, find your balls" deraadt@.
