hannken 905b6b7730 It is not the task of tmpfs_open() to check for unlinked nodes. 
Fix tmpfs_lookup() to always return ENOENT when looking up from
an unlinked directory.

christos 9d605174d9 Change the queue.3 *_END(&head) macros to NULL. Since we don't have CIRCLEQ 
anymore, all the macros expand to NULL anyway, so this improves readability.

rmind ccc45228d5 - tmpfs_construct_node: prevent from the new node construction if the 
directory was removed.  Fixes the crash reported by Nicolas Joly.
- tmpfs_reclaim: avoid race by checking tn_links with the vnode locked.
 2013-11-24 17:16:29 +00:00

rmind e63cf28e67 - Simplify tmpfs_update(), eliminate tmpfs_note_t::tn_status and deferred 
timestamp updates.  Fix some incorrect updates and plug some missing ones.
  Should fix PR/48385.

  entries were never added.

rmind 884c21d51e v7fs: replace malloc(9) with kmem(9), fix a memory leak and few missing 
mutex destruction cases in the error path.

Also, change tn_status to unsigned while here.

christos 15bc40ee73 mark variable __diagused 2013-11-10 03:20:20 +00:00
rmind 1f5dbc945b tmpfs: replace the broken tmpfs_dircookie() logic which uses the node 
address truncated to 31 bits (required for 32-bit readdir compatibility,
e.g. linux32).  Instead, assign 2^31 range using the following logic:
- The first half of the 2^31 is assigned incrementally (the fast path).
- When exceeded, use the second half of 2^31, but manage with vmem(9).

It will require 2 billion files per-directory to trigger vmem(9) usage.
Also, while here, add some fixes for tmpfs_unmount().

Should fix PR/47739, PR/47480, PR/46088 and PR/41068.
Thanks to wiz@ for stress testing.

the vnode has a reference.

rmind 20a51a9773 tmpfs: fix the zero-length symlink target case as NetBSD supports them. 2013-11-01 15:38:45 +00:00

rmind f8abe6cb77 tmpfs_alloc_node: it is less error-prone to store the link path with 
the NIL terminator included.  Adjust tmpfs_readlink() to exclude NIL.
Also, remove the check for zero-length and add some asserts.

Patch from Pedro Martelletto.

- tmpfs_link: remove unused variable.

hannken 85b4f7dccf Remove a bogus vrecycle() from udf_inactive(). Vrecycle() works on inactive 
vnodes while VOP_INACTIVE() should never be called on an inactive vnode.

rmind be67742670 tmpfs_remove: as per POSIX, "if the file's link count is not 0, the last 
file status change timestamp of the file shall be marked for update."

hannken 3881f4f3f9 Replace macro v_specmountpoint with two functions spec_node_getmountedfs()

dholland e63709eb76 The script for preparing an import of this nfs code. 2013-09-30 07:23:37 +00:00
dholland 6ca3558714 Import FreeBSD's "newnfs" nfs client and server code. This contains 
nfsv4 as well as new implementations of nfsv3 and nfsv2.

This import is from tonight's FreeBSD head and is unchanged from there
except for automated munging of rcsids, rearranging of paths, and an
autogenerated files.* file that might or might not be syntactically
valid. (I will check in the script that does this shortly.)

There is not the slightest chance this will configure yet, let alone
compile or run.
