Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.
= Hesiod has been added to libc (see hesiod(3)).
= A library routine for parsing nsswitch.conf and invoking callback
functions as specified has been added to libc (see nsdispatch(3)).
= The following C library functions have been modified to use nsdispatch:
. getgrent, getgrnam, getgrgid
. getpwent, getpwnam, getpwuid
. getusershell
. getaddrinfo
. gethostbyname, gethostbyname2, gethostbyaddr
. getnetbyname, getnetbyaddr
. getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr
= host.conf has been removed from src/etc. rc.network has been modified
to warn that host.conf is no longer used at boot time. In addition, if
there is a host.conf but no nsswitch.conf, the latter is created at boot
time from the former.

Do not panic on an uninitialized VOP_xxx() call. This was meant as a
sanity check, but it is too easy to run into, eg: making an ACL syscall
when no filesystems have the ACL implementation enabled.
The original reason for the panic was that the VOP_ vector had not been
assigned and therefor could not be passed down the stack.. and there
was no point passing it down since nothing implemented it anyway.
vop_defaultop entries could not pass it on because it had a zero (unknown)
vector that was indistinguishable from another unknown VOP vector.
Anyway, we can do something reasonable in this case, we shouldn't need
to panic here as there is a reasonable recovery option (return EOPNOTSUPP
and dont pass it down the stack).

Don't warn about unknown mount types, since they most likely simply mean
that the right module hasn't been loaded yet (and mount(8) will do so
when necessary).
Add refcounts to the "global" DEVFS inode slots, this allows us
to recycle inodes after a destroy_dev() but not until all mounts
have picked up the change.
Add support for an overflow table for DEVFS inodes. The static
table defaults to 1024 inodes, if that fills, an overflow table
of 32k inodes is allocated. Both numbers can be changed at
compile time, the size of the overflow table also with the
sysctl vfs.devfs.noverflow.
Use atomic instructions to barrier between make_dev()/destroy_dev()
and the mounts.
Add lockmgr() locking of directories for operations accessing or
modifying the directory TAILQs.
When sigaltstack is called with a stack size that's not smaller
than LINUX_MINSIGSTKSZ but smaller than MINSIGSTKSZ, cheat and
pass MINSIGSTKSZ to the kernel. This is a workaround.
1. IP_FW_F_{UID,GID} are _not_ commands, they are extras. The sanity checking
for them does not belong in the IP_FW_F_COMMAND switch, that mask doesn't even
apply to them(!).
2. You cannot add a uid/gid rule to something that isn't TCP, UDP, or IP.
XXX - this should be handled in ipfw(8) as well (for more diagnostic output),
but this at least protects bogus rules from being added.
Export the salient configuration items in a non-pxe-specific namespace
to allow commonality between varying platforms. This is a step
towards parsing the diskless configuration information with MI code
inside the kernel.
Export the interface hardware address to the kernel, so that it is possible
to determine the boot interface with certainty.
Export the NFS filehandle for the root mount to the kernel, so that the
kernel does not need to perform a mount RPC call.
Don't scan for the "right" network interface by shooting in the dark.
Assume that the nfs_diskless structure is correctly set up; the provider
ought to be getting it right.
Remove uidinfo hash table lookup and maintenance out of chgproccnt() and
chgsbsize(), which are called rather frequently and may be called from an
interrupt context in the case of chgsbsize(). Instead, do the hash table
lookup and maintenance when credentials are changed, which is a lot less
frequent. Add pointers to the uidinfo structures to the ucred and pcred
structures for fast access. Pass a pointer to the credential to chgproccnt()
and chgsbsize() instead of passing the uid. Add a reference count to the
uidinfo structure and use it to decide when to free the structure rather
than freeing the structure when the resource consumption drops to zero.
Move the resource tracking code from kern_proc.c to kern_resource.c. Move
some duplicate code sequences in kern_prot.c to separate helper functions.
Change KASSERTs in this code to unconditional tests and calls to panic().
Make the basic AIO functions, i.e., aio_read() and aio_write(),
work on the Alpha, at least, for the aio_qphysio() case. Specifically,
fix an unaligned access fault.

Add support for the SOHOware PCMCIA Ethernet card, model ND5100-E.
This seems to be a re-badged NDC (National Datacomms. Corp) card.
It needs a quirk entry due to lack of manufacturer tuple in the CIS.
For some reason, the 'Tx/Rx' LED on the connector module is inverted
such that it is off during network activity...
Good thing about these examples is that no one uses them, so they can
stay broken for months without anyone noticing.
The boot-conf command was changed as to reproduce the behavior of builtin
loader words precisely. As a result, it now always need an argument, possibly
0 indicating that no other arguments are being passed. This broke in a
non-deterministic way (ie, it could go on working as if everything was fine).
Implement readahead buffering for non-raw files. This drastically improves
the efficiency of byte-by-byte read operations on filesystems not already
supported by the block cache (especially NFS).
This should be a welcome change for users booting via PXE, as the loader
now reads its startup files almost instantly, instead of taking tens of
seconds.

Remove the SIGSYS handler and wrapper around the __getcwd() syscall.
It was kinda silly since the sigaction() syscall that it used to setup
the handler is more recent than __getcwd(), therefore it was useless
as the wrapper would have died before even getting as far as __getcwd(2).

Catch a few more bogosities in certain chipsets before they mess us up.
Some have dual host->PCI bridges for the same logical pci bus (!), eg:
some of the RCC chipsets. This is a 32/64 bit 33/66MHz and dual pci
voltage motherboard so persumably there are electical or signalling
differences but they are otherwise the same logical bus.
The new PCI probe code however was getting somewhat upset about it and
ended up creating two pci bridges to the same logical bus, which caused
devices on that logical bus to appear and be probed twice.
The ACPI data on this box correctly identifies this stuff, so bring on
ACPI! :-)

When dumping the 'found devices' list in verbose mode, actually show the
bus/slot/function numbers. The old PCI code used other markers or
something, but without it here under the new pci code it is very hard to
tell which device is which (this only affects bootverbose mode).

Yank out the NOPOLL conditionals. libc_r no longer needs it, and this
library depends on other things that come *way* later than poll() now
(sigset size changes in particular)
Throw out a considerable number of cards that have never been tested
on Alpha, primarily in the storage adapter area. Things like
Soundblaster-attached CDs, WD7000 etc for example. Try to get RELNOTES
for alpha to reflect reality a bit more.
* rewrite catopen() to remove duplicate code chunks and optimize
* if empty string is passed to catopen() as name argument then
catopen() will set errno to ENOENT (File not found), not EINVAL
* move search code to LOOKUP() macro to shrink amount of duplicated code
* move common resource freeing actions to __nls_free_resources() function
* exclude from build code related to MCLoadAll defintion since it is not

Make filt_aio() check the jobstate for JOBST_JOBBFINISHED (in addition
to JOBST_JOBFINISHED) in case the aio_read() or aio_write() was performed
via the high-performance physio method, i.e., aio_qphysio().
When we have both a rcsid and sccsid, ifdef 0 the sccsid. This
appears to be the standard FreeBSD way to do this. style(9) is silent
about this, however.
Don't print an error message if the bad option is '?'. This has been
in my tree for a long time. bde reviewed this once upon a time and
said it was OK, iirc. This also obviates the need to put ? in the
optstring argument to preclude the extra warning message which some
people think confuses users. When I made my getopt cleanups of a long
time ago, this was the compromise reached. I just neglected to commit
it until now.
