1cf445da3e Don't play rename & typecast games with kauth_cred_t, but rather

4224c1d885 * in getpages, make sure we always align our buffer size to the page size 
* in putpages, make sure we don't try attempt to push data in a page
  after eof.  also, skip blocks which bmap can't locate (see comment
  in code).

the effect: file systems with fs_bsize < PAGE_SIZE now work r/w

3c2765f1a3 Hide NetBSD kernel headers completely from ukfs. This includes creating 
accessors for:
  * struct mount & VFS ops
  * struct uio
  * struct vnode
  * struct vattr

and some namespace games for:
  * namei flags
  * VOPs
  * enum vtype

Also, split rump services into two categories: library private and public
(rump_private.h and rump.h, respectively).

As a result, it is now possible to compile and use the NetBSD kernel
file systems on Linux (and probably other systems too with very
little work), although the makefiles need a bit of work to make it
a pleasureable experience.
 2007-08-20 15:58:13 +00:00
pooka
34980d5637 Namespace management: do not call VOP_FOO directly from ukfs or 
p2k, but rather make the calls go through librump.  This avoids
having to include NetBSD kernel headers in userspace programs.
Stay tuned for some more mods of the same sort ...

6c71c22a44 Add "file system console", which is meant eventually to become a 
"console" to a file system, i.e. a tool for mounting any file system
image supported by rump and executing various commands on it.
Currently it's just a linear set of calls to ukfs routines and
serves mainly as a simple test program and ukfs usage example.

b926b490ec Add routines for pure userspace file system operation 
(i.e. no kernel involvement), namely:
* create, mknod, remove, mknod, rmdir, getdents, read, write, and link

Still obviously missing a few, but this is a start (I'm also searching
for the blessed orb of code quality, maybe someone has seen it?).

c360a79960 * split userspace file system access into two separate libraries:

	     independent of libp2k and/or puffs

643e56125f * move rump_vopwrite_fault() into history - we now support the file 
system faulting in pages if it does e.g. fragment reallocation
* get rid of rumpvm_findpage() and always use uvm_pagelookup()
* determine a vnode's cleanness by flagging it as being on the work
  list if we "take" a write fault and removing it from the worklist
  once pages are flushed.  There is no work list here, but at least
  there is symmetry with the kernel.

c3bc94628d Play catchup with ufs/ffs changes: compile subr_specificdata.c

36c0b176cc Fix it a bit & wait for the dust to settle. Also, enable UBC by default. 
ffs in userspace on top of puffs/p2k/rump is now stable enough to
host a make -j4 kernel build (well, at least my kernel build ...
but, yes, I am currently running that kernel on my desktop)

37698f56d6 Enable lfs in r/o mode, i.e. does not start lfs_clean-nerd and do 
any real trickery.  Unfortunately this was the easy part; r/w
support is going to make ascending naked, blind, illiterate, without
food and as an atheist look trivial.

427705465b Provide rumpmachine bswap.h, which makes bswapxx() call rumpuser 
directly instead of relying on a symbol in rumpkern.  I would like
to make it call the libc symbol directly, but I don't currently know
how to make it do that MI.

Makes hfs work (on i386), as it avoids endless recursion in bswap64().

daafee8742 Introduce RUMPs - Runnable Userspace Meta-Programs 
/sys/rump contains programs which run unmodified kernel code in an
emulated userspace environment.  The kernel environment is provided
by librump.  Currently supported are a number of file systems,
which by using puffs integrate seamlessly into the system and
provide a similar user experience to if the code was running as
part of the kernel.  Potential future rumpification targets include
for example parts of the networking stack and some device drivers.

This work was supported by Google Summer of Code 2007.
