pooka 357983cc1c Make P2K_WIZARDUID require a valid integer instead of defaulting to root. 2011-01-07 16:02:32 +00:00
pooka 0d0a5842f8 Document how to get debug info for the mount. 2011-01-07 15:50:40 +00:00
pooka 27daa694a2 In case of a P2K_DEBUG mount, dump mount point contents when the 
process receives SIGINFO.  Additionally, dump vnode status if the
process gets SIGUSR1 (can be quite quite verbose, therefore not
displayed with SIGINFO).
 2011-01-07 15:47:14 +00:00
pooka d32ef440df in case unmount fails (it never should), do a full mountpoint dump 2011-01-07 15:30:09 +00:00
pooka cc30c34a93 Remove the componentname-saving code since it was addressing 
SAVENAME/HASBUF/SAVESTART and they don't exist anymore (and the
removed code didn't compile on nb5).

pooka 4063bc515b Fix file handles. Problem reported & fix tested by kefren. 2011-01-07 10:18:06 +00:00

dholland b845056678 Add an INRELOOKUP namei flag. Sigh. (We don't need more namei flags.) 
However, because of a protocol deficiency puffs relies on being able
to keep track of VOP_LOOKUP calls by inspecting their contents, and
this at least allows it to use something vaguely principled instead of
making wild guesses based on whether SAVESTART is set.

Update libp2k to use INRELOOKUP instead of SAVESTART.

pooka 9670fcaf80 Remove dead code from previous revision. 2010-11-30 15:42:11 +00:00
dholland 297e393f26 SAVENAME and HASBUF namei flags have been removed; update accordingly. 
(pooka@ says not to worry about compat.)

pooka d33a80444e Simplify now that ukfs deals with being called from a thread which 
already has a rump lwp context.

Welcome to 5.99.32.

Discussed on tech-kern.

jruoho 3fe9db0422 Use standard section headers. 
Xref vfs(9), which could be slightly more elaborate.

pooka 9a9b93d40a Initialize "hasdebug" default deterministically. 2010-05-20 00:13:02 +00:00
pooka d16346a23e If P2K_DEBUG is given, also dump rump kernel event counters when 
file system is unmounted.
 2010-05-01 14:44:48 +00:00
pooka 30df4c9f8c If vfstype is MOUNT_RUMPFS, assume we don't actually want to mount 
a file system, but attach to the root in the fs namespace of a rump
kernel.

pooka 2734e549f0 Some _t purification. no functional change. 2010-04-14 14:15:48 +00:00
pooka 3454464e10 Technically we're supposed to use flags from the RUMP_NAMEI namespace 
instead of NAMEI directly.  Probably doesn't matter in practise,
since the chances of this running on non-NetBSD are low.  But make
it correct anyway.
 2009-12-23 01:15:11 +00:00
pooka 81eb543b62 Use NAMEI_INRENAME to improve the situation with detecting on when 
to save componentname instead of looking at SAVESTART.  Not perfect,
but better.  Also, try to be more forgiving of kernel bugs.

pooka 13777d56f1 Don't VOP_PUTPAGES(PGO_FREE) in inactive for tmpfs, since we now 
(after some changes to rump) actually free those pages, leaving
the tmpfs vnode feeling quite empty.
(the purpose of the flush is to avoid double caching between the
rump kernel and puffs vfs layer)

pooka a1c4673949 Adapt ukfs users to the new ukfs_part interface. 2009-12-03 14:27:16 +00:00

pooka 18382772a4 document P2K_WIZARDUID 2009-11-21 11:40:52 +00:00
pooka 251fbb35dc Report actual group array size instead of 0 (which always gives back 0 grousp). 2009-11-20 14:24:58 +00:00
pooka 96ae77ca39 Add "wizardmode", which allows to specify the uid which is used to 
access the file system instead of using the caller uid.  This is
useful for example when modifying the root fs image for an OS
installation without wanting to dance around as root on the host.

pooka a37ccec12c Default "recycle" to false in inactive. File system drivers do 
not always set it.
 2009-10-19 17:34:07 +00:00
pooka 38a8ac9c61 Split init routines a bit more to allow for p2k init without having 
to pass any real configuration data.  This benefits things like
rump_smbfs which need to init rump before running the userspace
mount routines (because they make rump system calls) but cannot
run p2k_setup() at that stage because it requires data provided by
the userspace mount routines.  And p2k_setup() in turn forks (to
detach), so it cannot be run after rump has been inited and threads
have been created.

want to perform actions after mounting.

pooka a06931db70 puffs might call getattr after we decided to recycle node. protect. 2009-10-07 20:56:29 +00:00
pooka 0605ce2bd4 Provide p2k_run_diskfs(), which acts like p2k_run_fs(), but taps 
into ukfs_mount_disk() instead of ukfs_mount()
 2009-10-07 20:55:25 +00:00
pooka b02819edcd don't double free p2m 2009-10-06 16:57:54 +00:00
pooka 5290e6c820 Give a p2k node an internal state. This allows us to do proper 
reference counting and not release nodes based just on puffs'
impression of if they are free.

This also allows us to reclaim vnodes already in inactive if the
file system so desires.  Some file systems, most notably ffs, change
file state already in inactive.  This could lead to a deadlock in
the middle of inactive and reclaim if some other puffs operation
was processed in between (as exposed by haad's open(at) test
program).

Also, properly thread the componentname from lookup to the actual
vnode operation.  This required the changes the rump componentname
routines.  Yes, the rename case is truly mindbogglingly disgusting.
Puke for yourself.
