8ba5efbd6f On sparc64 obtain the initiator ID to be used for SPI HBAs from the
Open Firmware device tree in order to match what the PROM built-in
driver uses. This is especially important when netbooting Fujitsu
Siemens PRIMEPOWER250 as in that case the built-in driver isn't used
and the port facts PortSCSIID defaults to 0, conflicting with the
disk at the same address.

637bfa488b Use _exit(2) system call directly instead of using exit(3) in signal
handler, as the latter is not guaranteed to be signal safe, and we
do not really care about flushing the stream during SIGINT.

7a657e630d Enhance the historic behaviour of raw sockets and jails in a way
that we allow all possible jail IPs as source address rather than
forcing the "primary". While IPv6 naturally has source address
selection, for legacy IP we do not go through the pain in case
IP_HDRINCL was not set. People should bind(2) for that.

This will, for example, allow ping(|6) -S to work correctly for
non-primary addresses.

4bc2b0b76d Require the option that's mapped be listed in the options file. This
will allow people with old config options to either have it just work
(if config is new enough), or get a version error (if their config is
about 7.0 or newer) rather than getting a cryptic error about
duplicated options in the options file, or getting an error about an
unknown option, at which point they'd update their config file only to
learn they need a new config, only to learn they didn't really need to
update their config file...  All this because our version checking was
in the wrong place for the past decade...

# hopefully this is the last change, and we'll be able to config with an
# 8.0 GENERIC file on stable/8 after I merge this change and add the
# compat options.

012ead2f2c Redo how we add compat options so as to be compatible with old
versions of config.  Remove support for the syntax OLD = NEW form the
options file, and instead have a new file $S/conf/options-compat.
This file will be parsed as OLD NEW on each line.  Bump version of
config.  Since nothing in -current ever used this, there's no hazards
for current users, so I'm not bumping the version in the
Makefiles.$MACHINE.  No need, really, for this version bump in
-current, but this was introduced into -stable before I realized the
version check was ineffective there, so the verison bump doesn't hurt
here and keeps the two branches in sync, versionwise, after the MFC.

90aa4f9e8c Move checking the version up from Makefile generation to just after
we've parsed the config file.  Makefile generation is too late if
we've introduce changes to the syntax of the metafiles to warn about
version skew, since we have to try to parse them and we get an parse
error that's rather baffling to the user rather than a 'your config is
too old, upgrade' which we should get.

We have to defer doing it until after we've read the user's config
file because we define machinename there.  The version required to
compile the kernel is encoded in Makefile.machinename.  There's no
real reason for this to be the case, but changing it now would
introduce some logistical issues that I'd rather avoid for the moment.
I intend to revisit this if we're still using config in FreeBSD 10.

This also means that we cannot introduce any config metafile changes
that result in a syntax error or other error for the user until 9.0 is
released.  Otherwise, we break the upgrade path, or at least reduce
the usefulness of the error messages we generate.

# This implies that the config file option mapping will need to be redone.

4c7421aadb It seems ale(4) controllers do not like to see TCP payload in the
first descriptor in TSO case. Otherwise controller can generate bad
frames during TSO. To address it, make sure to pull up ethernet +
IP + TCP header with options in first buffer. Also ensure the
buffer length of the first descriptor for TSO covers entire ethernet
+ IP + TCP with options and setup additional Tx descriptor if the
first buffer includes TCP payload.

7d11e744c1 - Rework the underlying ALQ storage to be a circular buffer, which amongst other
things allows variable length messages to be easily supported.

- Extend KPI with alq_writen() and alq_getn() to support variable length
  messages, which is enabled at ALQ creation time depending on the
  arguments passed to alq_open(). Also add variants of alq_open() and
  alq_post() that accept a flags argument. The KPI is still fully
  backwards compatible and shouldn't require any change in ALQ consumers
  unless they wish to utilise the new features.

- Introduce the ALQ_NOACTIVATE and ALQ_ORDERED flags to allow ALQ consumers
  to have more control over IO scheduling and resource acquisition
  respectively.

- Strengthen invariants checking.

- Document ALQ changes in ALQ(9) man page.

0d2e1c3e39 Clearing a page table entry's accessed bit (PG_A) and setting the
page's PG_REFERENCED flag in pmap_protect() can't really be justified.
In contrast to pmap_remove() or pmap_remove_all(), the mapping is not
being destroyed, so the notion that the page was accessed is not lost.
Moreover, clearing the page table entry's accessed bit and setting the
page's PG_REFERENCED flag can throw off the page daemon's activity
count calculation.  Finally, in my tests, I found that 15% of the
atomic memory operations being performed by pmap_protect() were only
to clear PG_A, and not change protection.  This could, by itself, be
fixed, but I don't see the point given the above argument.

Remove a comment from pmap_protect_pde() that is no longer meaningful
after the above change.

36f8c7ebef Make hash, type and ulimit available via execve().
These are specified by POSIX but are not special builtins, and therefore
need to be available via execve() and utilities like time, nohup, xargs.
(Note that hash was moved from the XSI option to the base in the 2008
standard.)

Like most of the POSIX "regular builtin commands", these need to be executed
in a shell environment for full functionality, although they may still be of
some use outside one.

Unlike the POSIX special and regular builtin commands, POSIX does not
require these to be found before a PATH search, although that could be an
oversight.

Like some of the utilities already provided by usr.bin/alias, these may lead
to confusing results when invoked from csh(1).

23f929dfe8 An NFSv4 server will reply NFSERR_GRACE for non-recovery RPCs
during the grace period after startup. This grace period must
be at least the lease duration, which is typically 1-2 minutes.
It seems prudent for the experimental NFS client to wait a few
seconds before retrying such an RPC, so that the server isn't
flooded with non-recovery RPCs during recovery. This patch adds
an argument to nfs_catnap() to implement a 5 second delay
for this case.
