(prefix related ioctl should only be called on router,
because host use dynamic address and prefix configuration mechanism,
and those prefix are managed separately with ones whih are assined
manually.)
Using recursion to traverse the recursive data structure for extended
partitions was never good, but when slice support was implemented in
1995, the recursion worked for the default maximum number of slices
(32), and standard fdisk utilities didn't support creating more than
the default number. Even then, corrupt extended partitions could
cause endless recursion, because we attempt to check all slices, even
ones which we don't turn into devices.
The recursion has succumbed to creeping features. The stack requirements
for each level had grown to 204 bytes on i386's. Most of the growth was
caused by adding a 64-byte copy of the DOSpartition table to each frame.
The kernel stack size has shrunk to about 5K on i386's. Most of the
shrinkage was caused by the growth of `struct sigacts' by 2388 bytes
to support 128 signals.
Linux fdisk (a 1997 version at least) can now create 60 slices (4 standard
ones, 56 for logical drives within extended partitions, and it seems to
be leaving room to map the 4 BSD partitions on my test drive), and Linux
(2.2.29 and 2.3.35 at least) now reports all these slices at boot time.
The fix limits the recursion to 16 levels (4 + 16 slices) and recovers
32 bytes per level caused by gcc pessimizing for space. Switching to
a static buffer doesn't cause any problems due to recursion, since the
buffer is not passed down. Using a static buffer is wrong in general
because it requires the giant lock to protect it. However, this problem
is small compared with using a static buffer for dsname(). We sometimes
neglect to copy the result of dsname() before sleeping.
Also fixed slice names when we find more than MAX_SLICES (32) slices.
The number of the last slice found was not passed passed recursively.
The limit on the recursion now prevents finding more than 32 slices
with a standard extended partition data structure anyway.
struct contains a major union for which lph_slp was being initialized
only for TCP connections, but accessed for all types of connections
leading to a crash. Also, a conditional controlling an nfs_slplock()
call contained an improper paren grouping, causing a second crash in
the UDP case.
The nqhost structure has been reorganized and lph_slp has been made a
normal structural field rather then a union field, and properly
initialized for all connection types.

- Add acl_dup() prototype
- Remove acl_calc_mask, which belongs in the editing library
- Introduce posix1e.3, a man page introducing POSIX.1e library calls

vintage system, well before the ppbus changes. When I called it an
"example" module, I meant as an example for the rest of the ppbus client
drivers, not that it was worthless. I'll mail my 5.8MB world.log to
anybody who doesn't believe me.

adds _np to a couple of function prototypes that provided more broad/useful
interfaces than POSIX.1e interfaces included.
Also, move from using a heuristic to identify POSIX.1e-semantic ACLs to
using different ACL types for non-POSIX.1e ACLs. This should clean up the
existing fuzzy logic that determined when acl_sort() should be applied
before kernel submission.
IRQ 2 was being unilaterally disallowed, which is only appropriate if
the interrupt hardware is the traditional chained PIC arrangement.

Dont use READ_CD on normal data reads (2048 bytes), too many old drives
doesn't support this command even if the std says "shall" :(, but still
use READ_CD on all other blocksizes.
Add the geometry to the ad probe, its still usefull.

Widen MAX_INITITATORS to 256- that's still not quite right, but will

does ignore DCD. Even TIOCMGET cannot read DCD as the firmware doesn't
report it. This has pretty interesting effects for ppp(8) which runs
in clocal mode and polls carrier (!). (Specialix's linux driver does
this too)
Also update the firmware to 3.0.6 for the SX cards, as apparently there
was a problem with floating (disconnected) DCD pins causing stray carrier
transitions, especially at port open time.
It seems to work here, and carrier loss is detected nearly immediately
rather than having to wait for a LQR timeout (a few minutes) before ppp(8)
gives up.

despite having a non-null cn_tab entry. This case now works the same
as if there is no physical console, except i/o at the kernel printf
level may still work. This frees drivers of physical console drivers
from the responsibility of attaching the device no matter what.

Dont be so verbose in the probe, only ONE line printed now, to get more

the ata_printf function, it saves alot of codelines.

Move the handling of next_writeable to userland.
Use the READ_CD command to read CD's. That enables us to read _anything_
