Remove the hardcoded 4 MB free kernel memory limit and replace it
by uvmexp.freetarg, as discussed on tech-kern.
Main purpose is to make tmpfs usable (as far as possible) on small memory
machines.
This is a bit experimental, but we need to give it some real world exposure
to see how well it works.

memory buffer, and could dereference a NULL pointer when particular

Limit check for 'data_len'. Otherwise a (un)privileged user can easily
panic the system by passing a huge size.
ok christos@
An (un)privileged user can easily make the kernel dereference a NULL
pointer.
The kernel allows 'data' to be NULL; it's the fs's responsibility to
ensure that it isn't NULL (if the fs actually needs data).
ok christos@
Some fs's - like kernfs - set their vfs_min_mount_data to zero. Add a check
to prevent an (un)privileged user from requesting a zero-sized allocation
(and thus a panic).
This thing is totally buggy: 'data_len' is modified by the fs, so calling
kmem_free with it while its value has changed since the kmem_alloc is far
from being a good idea.
If the kernel figures out that something mismatches, it will panic
(typically with kernfs).

Fix a race where thread1 runs VOP_REMOVE() and gets preempted in
tmpfs_reclaim() before the call to tmpfs_free_node().  Thread2
runs VFS_FHTOVP() and gets a new vnode attached to the node thread1

Change tmpfs_fhtovp() to check the generation number after
tmpfs_vnode_get() succeeded.

  Should fix PR/48385.

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.

- Rework and document inode reference counting.  Also document inode life
  cycle (destruction part).  Perform link counting in tmpfs_dir_attach()
  and tmpfs_dir_detach(), instead of alloc/free and arbitrary places.
  Fixes PR/44285, PR/44288, PR/44657 and likely PR/42484.

- Fix the race between the lookup and inode destruction.  Fixes PR/43167
  and its duplicates PR/40088, PR/40757.

- Improve tmpfs_rename() locking a little, fix kqueue event notifications
  and also fix PR/43617.  Add simplistic tmpfs_parentcheck_p(); to be
  expanded and used for further rename() locking fixes.

- Cache directory entry "hint" in the tmpfs node, add tmpfs_dir_cached(),
  and thus avoid unnecessary lookup in tmpfs_remove() and tmpfs_rmdir().

- Set correct _PC_FILESIZEBITS value in tmpfs_pathconf().  Fixes PR/43576.

- Few minor fixes.

Fix file handle operations for tmpfs by removing a now bogus test and
fixing the return value of tmpfs_fhtovp() in the not-found case.

When vmlocking2 was merged to head (Jan 2008 !!) the inode numbering was
changed.  Before inodes were numbered 2..tm_nodes_max-1 and after the
merge the numbers are derived from the nodes memory address.

Fixes PR #43605 (tmpfs file handles are broken)

- Don't leave nodes dangling in order to keep track of the inode generation
  number. Free them back to the pool as soon as the referenced file becomes
  unused. Using arc4random() for the generation and ino_t based off the

  system is going to give.
- Add assertion to catch empty directories with linkcount > 1 being freed.

Change the VFS_MOUNT() interface so that the 'data' buffer passed to the
fs code is a kernel buffer, pass though the length of the buffer as well.
Since the length of the userspace buffer isn'it (yet) passed through the mount
system call, add a field to the vfsops structure containing the default length.
Split sys_mount() for calls from compat code.
Ride one of the recent kernel version changes - old fs LKMs will load, but
sys_mount() will reject any attempt to use them.

New file system suspension API to replace vn_start_write and vn_finished_write.
The suspension helpers are now put into file system specific operations.
This means every file system not supporting these helpers cannot be suspended
and therefore snapshots are no longer possible.

Implemented for file systems of type ffs.

The new API is enabled on a kernel option NEWVNGATE.  This option is
not enabled by default in any kernel config.

Presented and discussed on tech-kern with much input from
Bill Studenmund <wrstuden@netbsd.org> and YAMAMOTO Takashi <yamt@netbsd.org>.

Welcome to 4.99.9 (new vfs op vfs_suspendctl).

Fix alignement problems for fhandle_t, exposed by gcc4.1.

While touching all vptofh/fhtovp functions, get rid of VFS_MAXFIDSIZ,
version the getfh(2) syscall and explicitly pass the size available in
the filehandle from userland.

Discussed on tech-kern, with lots of help from yamt (thanks!).

Kill the tmpfs(9) manual page; it was just documenting internal details of
tmpfs' "API" and was already rotting.

Instead, merge all the relevant comments into the code.  This includes
acknowledgements to Google's Summer of Code 2005 program (they were in the
AUTHORS section of tmpfs(9) before), so all the files need to be changed
to include this sentence alongside the title.  (Note that this was not a
requirement of the program.)

Apply the NFS exports list rototill patch:

- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
  function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
  file sys/nfs/nfs_export.c.  The former was becoming large and its code
  is always compiled, regardless of the build options.  Using the latter,
  the code is only compiled in when NFSSERVER is enabled.  While doing this,
  also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
  path and a set of export entries.  At the moment it can only clear the
  exports list or append entries, one by one, but it is done in a way that
  allows setting the whole set of entries atomically in the future (see the
  comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
  that it becomes file system agnostic.  In fact, all this whole thing was
  done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
  exports initialization; done internally by the kernel when initializing
  the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
  subsystems can run arbitrary code upon receipt of specific VFS events.
  At the moment, this only provides support for unmount and is used to
  destroy NFS exports lists from the file systems being unmounted, though it
  has room for extension.

Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments
and advice in the development of this patch.

Nodes cannot use the '0' identifier or they will be skipped by readdir.
E.g., the root node's '.' and '..' directory entries did not appear in
a directory list, because the root node always holds the first id.

wiz@ remembers that the preferred way to spell file-system in NetBSD is
file system.

Revision 1.1 / (download) - annotate - [select for diffs], Sat Sep 10 19:20:51 2005 UTC (9 years, 1 month ago) by jmmv
Branch: MAIN

Initial addition of tmpfs, an efficient memory file-system.  This project
was developed as part of Google's Summer of Code 2005 program.  This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*.  Therefore, it is disabled by
default in all kernels.  However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

OK'ed by my project mentor, William Studenmund (wrstuden@).
