add support for an ATAPI attachment for 'sd'.
...
fix 'cd' driver's NCD_SCSI bogosity (was using testing wrong macro!)
clean up in various ways:
* make common atapi_mode_{sense,select}() functions.
* put ATAPI data structures in more sensible headers, split up by
device type.
* include headers a bit more carefully.
* pass flags to attachment-specific cd functions, and use them.
* get rid of SCSI bits in scsipi_base.h's scsipi_make_xs(), move
them into the correct place in scsi_base.c.
* fix minor typo in struct name in scsipiconf.h (which was apparently
never used except in a #define later in the same file).
* use __attribute__ to force 4-byte alignment for xs command store,
so that architectures trying to bus_space_write_multi_N() (where
N > 1) that data to a controller won't lose.
* clean up a few comments in typos, and make a few #defines easier to
understand/maintain.
* rename cd_link.h to cdvar.h (via repository copy). This is exactly
what a 'var' file is supposed to be.

Various cleanups and bug fixes to the wdc/wd code:
...
* Fix bug in wdc that would overflow ATAPI transfer length.
* Improve wdc probe code so that 'wdc' is probed in if present
even if there are no drives attached, and so that it works
properly even if the only device is an ATAPI slave.
* bus_space-ify.
* split the ISA attachment from the wdc driver, and remove
ISA dependencies from non-ISA files.
* claim that wd and wdc are now machine-independent (probably not
completely true, but mostly so; they at least work on arm32 and
i386).
* Various other minor fixups and cleanups, some of which were pointed
out by Kazuki Sakamoto.

* Fix a train-load of bugs, mostly present in one of these categories:
...
- "out of resource" errors cause receive buffer chain corruption
- resets can confuse the interrupt handler
- multi-cast setup causes receive buffer chain corruption
- shared memory setup incomplete
* Enhance effiency by avoiding unnecessary shared memory access,
improved handling of receive frame & buffer descriptors, and
introducing an `asynchronous' option when issuing 82586 commands.
* Exclusively use offsets relative to the bus handle representing the shared
memory area to formulate accesses to the chip's data-structures. The
front-ends provide glue functions that cater to the chip's endian-
sensitivity, to perform the actual device access (note: single-byte
accesses are done here using `bus_space_{read,write}_1()').
This concludes the transformation into a bus-independent driver module.

Implement passing credentials as ancillary data on Unix domain sockets,
...
enabled with the LOCAL_CREDS socket option on the listener. Semantics are
similar to BSD/OS's:
- Creds are available with first data on SOCK_STREAM, and with every datagram
on SOCK_DGRAM.
- It is not possible to forge credentials.
Different in that:
- Different credential data structure (ours does not rely on the format
of internal kernel data structures, and does not pass the login name).
- We can pass creds and file descriptors at the same time (this does not
work in BSD/OS).
Luke Mewburn <lukem@netbsd.org> gets credit for inspiring me to implement
this. :-)

1998-01-06 00:35:42 +00:00
a8f80ad4fd
Fix a bogosity apparently inherited from when the Utah 4.3BSD code base
...
was converted to use Mach VM for Net2/4.4BSD. The user segment table
pointer was originally stored in the PCB. When Mach VM came along,
however, it was also stored in the pmap, and loaded into the PCB in
pmap_activate(). pmap_activate() would then note that the PCB's USTP
was now in sync with the pmap's USTP, and the low-level context switch
code would use the value from the PCB.
However, pmap_activate() would also load the hardware MMU context if
the pmap was the current pmap (or, in the case where pmaps can be shared,
such as in NetBSD, if the proc was the current proc). The low-level
context switch code would then reload the hardware _again_ using the
USTP from the PCB.
However, the optimization of not calling pmap_activate() if "stchanged"
was false ended up causing some processes to use stale USTP values from
the PCB when the low-level context switch code reloaded the hardware!
This was noticed by using a real vfork(2) (which worked for some time
before failing, surprisingly!)
Since I'm hard pressed to find any real optimization here (since the
hardware was always reloaded once, sometimes twice!), the code now always
calls pmap_activate(), which uses the correct USTP value (the one in the
pmap). The PCB's USTP is now ignored, and should eventually be g/c'd.
Another optimization can actually be performed, and I have added a comment
describing what it is, but have not yet implemented it.
Also note that most of the loadustp() functions where actually incomplete.
This has been corrected. These functions should probably be split up into
MMU-specific operations, and called indirectly, rather than doing constant
run-time decision making based on values that will never change during the
course of a boot's lifetime.

so_linger is used as an argument to tsleep(), so was stuffed with
clockticks for the TCP linger time. However, so_linger is set directly from
l_linger if the linger time is specified, and l_linger is seconds (although
this is not currently documented anywhere). Fix this to set the TCP
linger time in seconds, and multiply so_linger by hz when tsleep() is
called to actually perform the linger.

Fix the stat(2) ABI problem noticed by Curt Sampson and Chris Demetriou.
...
The problem is that the timespec structures now how 7 32-bit values before
them, which causes them to be implicitly padded on the Alpha (because the
timespecs have an alignment of 64 bits). However, the alignment constraints
changed if _POSIX_SOURCE was defined (thus replacing the timespecs with
time_ts and longs). This had no effect on 32-bit architectures, but changed
the offsets of several stat structure members on the Alpha.
XXX The ABI has not changed; explicit padding is added in the _POSIX_SOURCE
XXX case, enabled by an #ifdef __alpha__. This should be changed if the
XXX stat(2) ABI is ever changed again (e.g. if we change time_t to 64 bits).

New vfork(2) implementation, whith semantics matching those of the original
...
3BSD vfork(2), i.e. share address space w/ parent and block parent.
Keep statistics on the total number of forks, the number of forks that
block the parent, and the number of forks that share the address space
with the parent.

- Adjust so that access to the PCB is not required in most pmap functions.
...
Store the page {0,1} base and length registers in the pmap structure,
and implement pmap_activate(), which stores them in the PCB (for the
hardware's use).
- Re-implement pmap_pinit(); allocate the PTEs here, not in cpu_fork().

- Remove the PCB pointer from the pmap structure. Instead, store the
...
page {0,1} base and length registers in the pmap structure. They will
be loaded in to the PCB when the process's address space is activated
by way of pmap_activate().
- Remove pmap_pinit() macro; it's now a real function.
- Prototypes for pmap_pinit(), pmap_activate(), pmap_deactivate().
