520acca96b Mark perfused_panic as dead. Canonical form of infinite loops is 
for (;;). Remove completely redundant NOTREACHED markers.

9724ab82d4 Make sure perfused exit when the filesystem crashed, so that unmount 
is done. Failure to do so caused deadlocks, with operation that
held a lock on the root vnode and got stuck in perfused forever.

Approved by releng.

109f5fba24 - remove dup included files 
- use intptr_t instead of long where appropriate
- use perfused_ instead of perfuse_ for our own functions.
- more static
Fixes namespace collision of perfuse_mount with this and libperfuse.

fb0fa57f18 Fix creds passed to FUSE when requests are done on behalf of the kernel. 
We previously sent uid/gid set to -1, we now set it to 0.

26381d518d Use SOCK_SEQPACKET in perfuse if available. This fix file operations hangs 
where the FUSE filesyste replied to an operation and got an ENOBUFS it did
not handle.

We now are also able to cleanly unmount

33c1bbe9da - fix warnings 
- try to handle ENOBUFS in a nicer way
- use errx() for usage message, not err(), as we do not waht strerror(errno)

160a586559 Interm hack raising buffers for /dev/fuse socket used in the filesystem. 
This works around read(2) system callsfailing with ENOBUFS.

This is a hack bedause there is no way to know that 4 * FUSE_BUFSIZE
will be enough to hold queued FUSE frames. It seems good enough at
mine.

7ba588b3fb - Add debug santity checks

e9a8a6acc0 - Use SOCK_DGRAM instead of SOCK_STREAM, as the filesystem seems to 
assume datagram semantics: when using SOCK_STREAM, if perfused sends
frames faster than the filesystem consumes them, it will grab multiple
frames at once and discard anything beyond the first one. For now the
code can work both with SOCK_DGRAM and SOCK_STREAM, but SOCK_STREAM
support will probably have to be removed for the sake of readability.

- Remeber to sync parent directories when moving a node

- In debug output, display the requeue type (readdir, write, etc...)

1e672db8d2 - Do not checkfor peer credentials when perfused is autostarted and 
therefore runs with filesystem privileges

- shut up warnings and debug messages when perfused is autostarted

- make perfused patch modifiable with CFLAGS for easier pkgsrc integration

- Fix build warnings

1326029781 - if perfused is not already started (cannot connect to /dev/fuse), 
FUSE filesystems will attempt to start it on their own, and will
communicate using a socketpair

- do not advertise NULL file handle as being valid when sending themback to the FUSE filesystem.

- unmount if we cannot talk to the FUSE process anymore

- set calling process gid properly

- debug message cleanup

a18d4c5a69 perfused(8) creates a /dev/fuse socket and performs PUFFS to FUSE relaying. 
This is still a work in progress.
