connect to their 1-wire bus like the DS2404 "EconoRAM Time Chip"

* Interface function definitions for this kind of chips. Currently only
low-level byte_read and _write, implenented as inline functions.
This functions take a struct ds_handle * (also defined here), which contains
pointers to bit-read/write and reset functions.
Eventually, prototypes for memory-access functions should go here, and the
1-wire bus should be made a BSD auto-configuration bus.
fixed in FreeBSD by John Polstra:
Fix a bug (apparently very old) that can cause a TCP connection to
be dropped when it has an unusual traffic pattern. For full details
as well as a test case that demonstrates the failure, see the
referenced PR (FreeBSD's kern/3998).
Under certain circumstances involving the persist state, it is
possible for the receive side's tp->rcv_nxt to advance beyond its
tp->rcv_adv. This causes (tp->rcv_adv - tp->rcv_nxt) to become
negative. However, in the code affected by this fix, that difference
was interpreted as an unsigned number by max(). Since it was
negative, it was taken as a huge unsigned number. The effect was
to cause the receiver to believe that its receive window had negative
size, thereby rejecting all received segments including ACKs. As
the test case shows, this led to fruitless retransmissions and
eventually to a dropped connection. Even connections using the
loopback interface could be dropped. The fix substitutes the signed
imax() for the unsigned max() function.
Bill informs me that his research indicates this bug appeared in Reno.
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.
("filename" must be processed by parsebootfile() first).

- make some "booting..." output match reality
- print '\n' and '\b' more controlled

- Update using m68k asm.h macros
- Move initialization towards the front of the file
- Rename mac68k_buserr_addr to m68k_fault_addr
- Reorganize trap 15 handler, similar in structure to -- though not as
complete as -- the hp300 version
- Reorganize doboot() for easier integration of external cache, and
make room for the latter (#ifdef __notyet__)
- General garbage collection of unused code/data
_buserr point to the 68020/030 buserr code _only_. This has broken access
error handling in the 060 support code.
This is repaired by jumping to _buserr60 from the 060SP, and by providing
a _buserr60 label identical to the _buserr in the unchanged m68k ports
using the 68060.

socket names:
- In unp_setsockaddr() and unp_setpeeraddr(), if the socket name can't
fit into a single mbuf, allocate enough external storage space to
hold it.
- In unp_bind() and unp_connect(), perform a similar operation, but allocate
one extra byte, and ensure that the pathname is nul-terminated.
Many thanks to enami tsugutomo <enami@cv.sony.co.jp> for the sanity
checking.
- Add a comment describing my feelings about this interface, in general.
- Remove the COMPAT_OLDSOCK length hack. Instead, if the socket argument
is too long to fit in an mbuf, allocate enough external storage to
hold it.
- If the socket argument is a sockaddr, don't allow the length to be
greater than 255, as that would overflow sa_len.

This, incidently, may have been causing user errors in initializing
new disks, as described in (now closed) pr-2729 from Scott Reynolds,
because users typically don't try to edit their c partitions to be
"correct".

- Correctly deal with branch taken vs. branch not taken cases, and
self-branches.
- General cleanup, including types botches.

formats in DDB:
- Reverse the sense of the symbol format #ifdef... i.e. instead of
"#ifndef DB_NO_AOUT", use "#ifdef DB_AOUT_SYMBOLS". This is pulled
in from <machine/db_machdep.h>.
- Change the signature of X_db_sym_init(). Instead of int * and char *,
it now takes void *'s for the start and end of the symbol table.
- In X_db_sym_init(), check that the pointer to the beginning of
the symbol table is aligned.
- X_db_symbol_values() now takes a "db_symtab_t *symtab" argument.

This can happen during perfectly normal operation if:
(a) We are using DMA to select a target, and
(b) we are interrupted by another target reselecting us.

Every ccb locks 64k of memory for dma buffers.
Instead of AHA_CCB_MAX ccbs using 1MByte only sc_link.openings ccbs

- Disallow < 1 values for SO_SNDBUF, SO_RCVBUF, SO_SNDLOWAT, and

- For SO_SNDLOWAT and SO_RCVLOWAT, don't let the low-water mark get
set above the high-water mark. Behavior is now consistent with
BSD/OS: If such an attempt is made, silently truncate to the high-water

greater flexibility in its use. Additionally, add support for "geometry
emulation". This allows the "geometry" of the "disk" to be specified
at config time, providing near-perfect emulation of disklabel-less floppies,
CD-ROMs, etc., including non-512-byte sectors. If a geometry is not
specified at config time, a default based on 1M cylinders will be used.
