jakllsch 3c644b8a5a Bring mount_psshfs user/host/path argument processing in line with sftp(1). 2011-08-25 19:49:05 +00:00
riastradh 772f45cfc9 Cache vattr in psshfs's setattr. 
This means within the cache window, a setattr that wouldn't change the
remote file's attributes from our current view of them will not be
relayed to the server and wait for the server to answer.  Thus, e.g., a
process with a periodic timer interrupt that calls open(2) in a loop
can make progress with much higher probability than without caching.

XXX The test case doesn't work, so it's currently disabled.  It needs
to stop the child of sshd that is handling an sftp session, not sshd
itself, and it's not obvious how to do that.

pooka cf3a71d4a7 Add rump_au-naturel, which instead of mounting a file system inside 
the rump kernel just attaches to / in said rump kernel instance.
This is mostly useful in case wanting to see what nodes components
create (see Makefile).

pooka 326638b53f In case we create a file, reclaim the vnode, and lookup the file 
without the directory timeout expiring, we get vattr_null as the
attributes for that file.  Ensure that we always report sane
attributes by getting them from the server if this is the case.
(also, sprinkle some const)

Fixes problem reported by dyoung.   But wait!  The bug's medallion
begins to glow!  The bug looks much better!  I crumble to dust.

There's probably another similar bug related to "lazy open".  It
will trigger if we reclaim a node before the response to the open
arrives.  Even the comments (typoless) know about this bug ...
But verifying it exists and fixing it will have to wait for another
day.

pooka c11c0f21f8 Not Quite MFS 
Instead of copulating with newfs to produce a new FFS image into
memory, mmap() a given existing image and pass that as the backing
store.  If -s is given, mmap is done with MAP_SHARED and changes
are kept across mounts, else MAP_COPY (i.e. MAP_PRIVATE for us) is
done and changes are lost when the server exits.

Note: -s does not guarantee any kind of file system safety whatsoever
and in case of kill, crash, exit or other form of elusion,
everything will be, according to our theme, quite screwed.

pooka 73655f9fb0 Save "." attributes in readdir. This fixes the root link count 
after readdir is called for the root dir the first time (yes,
there's still a window of wrong link count after the fs is mounted.
it's currently quite difficult to call sftp_readdir() from outside
the main loop).

Should fix "find /mnt" problem for a mountpoint with more than the
"guessed" amount of subdirectories, as reported by dyoung.

pooka 7face90494 statvfs: 
Since bresvd is not available from the server, calculate:
	bresvd = bfree - bavail.

Then df calculates:

can write to the fs.

 2009-10-18 16:02:15 +00:00
pooka 2d07f409b9 Use write through cache here too. Doesn't make the same kind of 
difference as with smbfs since nfs is "stateless", but better to
have the data on the server ASAP in case some other nods wants to
use it.

pooka b0d965c6f5 Add rump_smbfs. It's innards are different from most file systems 
in two respects:
    * in addition to vfs (and networking), it depends on kernel
      device code to provide /dev/nsmb
    * mounting involves having lengthy chats with the kernel smb
      device instead of the typical "parse args and mount(2) away".

Seems to be pretty stable, at least data seems to flow over it
faster than over in-kernel nfs.

loading, since ufs was not really a module.  librumpfs_ufs is now
obsoleted and ffs consumers should be linked solely against
librumpfs_ffs.
