Change the way shutdown is handled for log file.
pmc_flush_logfile is now non-blocking and just ask the kernel
to shutdown the file. From that point, no more data is
accepted by the log thread and when the last buffer is flushed
the file is closed.
This will remove a deadlock between pmcstat asking for
flush while it cannot flush the pipe itself.
- Reorganize code in 'plugin' to share log processing.
- Kcachegrind (calltree) support with assembly/source
code mapping and call count estimator (-F).
- Top mode for calltree and callgraph plugin (-T).
Fix mptutil's method for locating disk devices attached to a specific
mpt(4) controller. Previously, the code assumed that multiple match
patterns provided to an XPT_DEV_MATCH request were ANDed together.
Instead, they are ORed. Instead, to match peripherals for a specific bus,
one query needs to be performed to lookup the path ID of the bus. A second
query can then be performed matching peripherals attached to that path.
This approach also makes the code a bit cleaner as the returned match
results do not mix buses and perphierals.
- Don't emit a warning in 'show adapter' if the IOC2 or IOC6 pages are not
present. mpt(4) controllers that do not support RAID do not have an IOC6
page, for example.
- Correct a check for a missing page error in a debug function.
Don't consider non-existence of a PID file an error, we should be able
to proceed anyway as this most likely mean that the process has been
terminated. [1]
Add a new option, -P, which reverts newsyslog(8) to the old behavior,
which stops to proceed further, as it is possible that processes which
fails to create PID file get screwed by rotation. [2]

Add ip4.saddrsel/ip4.nosaddrsel (and equivalent for ip6) to control
whether to use source address selection (default) or the primary
jail address for unbound outgoing connections.
This is intended to be used by people upgrading from single-IP
jails to multi-IP jails but not having to change firewall rules,
application ACLs, ... but to force their connections (unless
otherwise changed) to the primry jail IP they had been used for
years, as well as for people prefering to implement similar policies.
Note that for IPv6, if configured incorrectly, this might lead to
scope violations, which single-IPv6 jails could as well, as by the
design of jails. [1]

Simplify handling of MTREEFILE relative to DESTDIR
Make the message about a missing MTREEFILE combined with -U
more informative
MFC r200425:
Over time things that used to be files/directories/links can change
to something else. So add code to detect when things don't match and
give the user choices about how to fix it.
If we're using -P and something in the above check needs to be moved
we need to have the directory there for it, so create it at the
beginning and delete empty versions of it at the end.
The case where something used to be a file or link and now is supposed
to be a directory (e.g., /etc/security) is especially dangerous, so
make failure to install a necessary directory in $DESTDIR a fatal error.
MFC r200700:
In the places where find is used that the user may see the results,

MFC r200701:
Fix an indentation issue, no functional changes
MFC r200708:
Fix a problem with how mergemaster handles the hard links for /.cshrc
and /.profile. The problem is that install(1) will unlink the old file
before it installs the new one, which means that in the best case we
have to compare the changes for the old file twice.
So, change the logic to first test to see if the link exists, then
install the file. Then if the link was there and we're using -i, just
create the link in /root and be done with it. Otherwise display the
message to the user and give them the option.
Because we are now sorting things before doing the comparison we can
know conclusively that the files in / should be the sources, and the
files in /root will be the targets, so adjust the paths accordingly.
While I'm here, split a too-long error message into two lines and
just return at the end of handling these files instead of setting
the variable that says "do nothing" and then returning at the end
of the function anyway.
MFC r201291:
Add some patches contributed by jhb:
1. Don't prompt the user for "-U but no db" error if we're using -a
2. Add an option to delete stale rc.d files automatically if the user
has DELETE_STALE_RC_FILES in their rc file. Lack of command line option
for this is not an oversight.
3. Add []'s around the terminal $ for the $FreeBSD$ test for -F
For one bug raised by jhb I did a more thorough solution:
There were a lot of things that "snuck in" between the end of the test
for -r and the start of the comparison. One of them is the creation of
the mtree db, as pointed out by jhb. Fix this problem more thoroughly
by moving the end of the test down to where it should/used to be, right
before the comparison. As a result, indent the interloping code to match.
MFC r201292:
Document the DELETE_STALE_RC_FILES option introduced in r201291. This is

for a couple of options.

Update copyright date
Update delete_temproot() to include the error message if it fails,
and clean up the places where it's called.

delete it without prompting. This should make "automated" runs of
mergemaster without -a a little easier.
Document the new behavior in the man page.

-------
The proxy arp entries could not be added into the system over the
IFF_POINTOPOINT link types. The reason was due to the routing
entry returned from the kernel covering the remote end is of an
interface type that does not support ARP. This patch fixes this
problem by providing a hint to the kernel routing code, which
indicates the prefix route instead of the PPP host route should
be returned to the caller. Since a host route to the local end
point is also added into the routing table, and there could be
multiple such instantiations due to multiple PPP links can be
created with the same local end IP address, this patch also fixes
the loopback route installation failure problem observed prior to
this patch. The reference count of loopback route to local end would
be either incremented or decremented. The first instantiation would
create the entry and the last removal would delete the route entry.
r201543
-------
The IFA_RTSELF address flag marks a loopback route has been installed
for the interface address. This marker is necessary to properly support
PPP types of links where multiple links can have the same local end
IP address. The IFA_RTSELF flag bit maps to the RTF_HOST value, which
was combined into the route flag bits during prefix installation in
IPv6. This inclusion causing the prefix route to be unusable. This
patch fixes this bug by excluding the IFA_RTSELF flag during route
installation.
