interrupt thread.
The sleepq implementation required for callouts is horrible, kludged
only for callouts, and generally unacceptable. It needs revisiting,
but I'm not sure yet should rump or kern_timeout be improved. It's
almost untested as of now, but committing this will give me some
maneuvering space while letting application compile.
execute them simply in the context of the scheduling code, as this
does not work for all applications (e.g. networking soft interrupts).
Rather, schedule them and execute them from a separate context.
Also provide a timer which for now executes just hardclock_callout()
(well, at least after callouts are included in librump, which is
soon).
for any sensible operation when running the entire TCP/IP stack in
userspace (as opposed to libsockin which uses host kernel networking
to provide PF_INET).
While this basically works (although it is quite barebones), it
depends on some bit of cleanup in librump and is not built by
default yet.
which delegates the work to host kernel sockets. This does not
run the entire kernel TCP/IP stack in userspace and therefore does
not require the ability to send or receive raw packets. This
implies that root priviledges are not required. As already said
above, only supports UDPv4 for now. Extending should be easy.
to the root vnode. Properly fixing this would require fixing p2k,
which would require fixing puffs, which has some optimizations,
which are incompatible with kernel file systems... guess my Eyes
of the Overworld were misplaced at that time.
the other mount binaries do. Now syspuffs can be used to run all
puffs file systems as utilities. This includes fuse file systems
and becomes interesting with the fs-utils project. We can now do
e.g. this:
ReFUSE ntfs-3g:
golem> echo hello | fsu_write/fsu_write ntfs-3g puffs ~/img/ntfs.img dafile
golem> fsu_cat/fsu_cat ntfs-3g puffs ~/img/ntfs.img dafile
hello
golem>
puffs sysctlfs:
golem> fsu_ls/fsu_ls mount_sysctlfs puffs sysctl -l ddb

Same works for psshfs etcetc.
In other words, this provides total integration for "normal"
in-kernel file systems and puffs/fuse file systems on the ukfs
library level.
Note: implementation is still "first stab" and the fs-utils usage
will no doubt change.
