via sysctl(8). The initial value of maxprocperuid is maxproc-1,
that of maxfilesperproc is maxfiles (untill maxfile will disappear)
Now it is at least possible to prohibit one user opening maxfiles

requires complications to adjust the offsets to relative when a block
containing the label is read and back to absolute when such a block is
written. The adjustment is not made on the whole disk slice.
Don't allow setting the offset of partition C to nonzero in in-core labels.
This will cause some (nonstandard) disktab entries to fail. They will
need to be changed to have relative offsets (and no partitions outside
of the slice).
Don't write protect the (nonexistent) label on the whole disk slice.
Writing labels and bootstraps should work right now (except if there is
no DOSpartition table).
Slice 0 is now for the first BSD slice. The first BSD slice is
the first DOSpartition with id 0xa5 or the whole disk if their
are no DOSpartitions (except the latter is not yet implemented).
Existing partitions on it work the same as in 2.0 except the
'd' partition is no longer special and partitions are relative
to the skice.
Slice 1 is now for the whole disk and gets a read-only label
describing the disk. Previously, slice 0 was for the whole disk
and there was no label on it.
Slices 2-31 are for DOSpartitions. Slice 0 is an alias for one
of these if there is a BSD slice. Previously, slices 1-31 were
for DOSpartitions.
diskslice_machdep.c:
Expand whole disk slice to include all DOSpartitions. More work
is required for >1024 cylinders and to rewrite the label iff the
driver is unsure about the geometry.
subr_diskslice.c:
New function dsisopen() to help handle media changes.
mapping from numbers to names is messy for backwards compatibility.
E.g., for driver "sd", unit "0":
slice 0: omit the slice number for compatibility; names are sd0[a-h].
slice 1: omit the partition letter 'c' because the whole disk device
shouldn't have anything to do with partitions; sd0 is the
only name.
slices 2-31: subtract 1 from slice number to compensate for the
compatibility slice 0; names are sd0s[1-30][a-h].
- Overflow now calculated right
- Close works ok,does not looses tty
- Better overflow handling now the snooping stops
on overflow,but programm notified and can reconnect if
it want to..Default maximal buffer set to 664 K and this
is probably too much..:)))
Utility still to come
Restore fixes to flushing that were lost in the previous commit.
Clean up snoop changes.
Add my TODO list from 1.1.5. The improvements in 1.1.5 should be "obtained"
first.
Users-beware..
It is tested and working for me but probably have some bugs i
didn't noticed so test it and reply...
It can:
look at what's sent to the user from tty device
snoop on pty's,vty's and serial tty's
It (still) can't:
write to tty
see what user types in local echo mode
It is probably bad styled and
very dependant on tty_pty.c,sio.c and syscons.c
I would be really happy if another ppl would make their
changes because i am not sure this is the best snoop
we can have..but it is good..:)))))
Bruce finally caught this bogon for me, Thank you Bruce !
Due to some part of the VM/buffer/pmap magic doing clustering, this bogon
managed to work better than 99.9% of the time. Amazing.
If You ever again see a weird message from the gzip code, please tell me.
TS_WOPEN state when CLOCAL is toggled from on to off while there
is no carrier. There is no way back, and with sio there is no way
forward either (TS_ISOPEN will never be set again for the current
open). This bug was observed in 1.1 and was fixed in 1.1.5.
argument is now more than just a single flag. (kern_malloc.c)
Used new M_KERNEL value for socket allocations that previous were
"M_NOWAIT". Note that this will change when we clean up the M_ namespace
mess.

Now it matches the man page and also the only other commercial implementation
i have found so far ( Solaris 2.x).
Changed the name from ss_base to ss_sp.
implemented the ability to limit bufferspace by memory consumed. (vfs_bio.c)
Fixed recently introduced bugs that caused extra I/O to happen in some
cases. (vfs_cluster.c)

Moved various pmap 'bit' test/set functions back into real functions; gcc
generates better code at the expense of more of it. (pmap.c)
Fixed a deadlock problem with pv entry allocations (pmap.c)
Added a new, optional function 'pmap_prefault' that does clustered page
table preloading (pmap.c)
Changed the way that page tables are held onto (trap.c).

the physical device is closed. Previously only the reverse case was handled.
Abuse the cdevsw interface instead of the vfs interface to do this.
Remove unnecessary #includes.
