46be218dce The PADLOCK_RNG and RDRAND_RNG kernel options are now devices.
Thus "device padlock_rng" and "device rdrand_rng" should be
used instead of "options PADLOCK_RNG" & "options RDRAND_RNG".

0dc59c0fac Add a note that if you were WITH_ICONV before, you should turn on
WITH_LIBICONV_COMPAT.

0ff204bbd1 The iconv in libc did two things - implement the standard APIs, the GNU
extensions and also tried to be link time compatible with ports libiconv.
This splits that functionality and enables the parts that shouldn't
interfere with the port by default.

WITH_ICONV (now on by default) - adds iconv.h, iconv_open(3) etc.
WITH_LIBICONV_COMPAT (off by default) adds the libiconv_open etc API, linker
symbols and even a stub libiconv.so.3 that are good enough to be able
to 'pkg delete -f libiconv' on a running system and reasonably expect it
to work.

I have tortured many machines over the last few days to try and reduce
the possibilities of foot-shooting as much as I can.  I've successfully
recompiled to enable and disable the libiconv_compat modes, ports that use
libiconv alongside system iconv etc.  If you don't enable the
WITH_LIBICONV_COMPAT switch, they don't share symbol space.

This is an extension of behavior on other system.  iconv(3) is a standard
libc interface and libiconv port expects to be able to run alongside it on
systems that have it.

Bumped osreldate.

c319ea15f4 opensolaris code: translate INVARIANTS to DEBUG and ZFS_DEBUG
Do this by forcing inclusion of
sys/cddl/compat/opensolaris/sys/debug_compat.h
via -include option into all source files from OpenSolaris.
Note that this -include option must always be after -include opt_global.h.

Additionally, remove forced definition of DEBUG for some modules and fix
their build without DEBUG.

Also, meaning of DEBUG was overloaded to enable WITNESS support for some
OpenSolaris (primarily ZFS) locks.  Now this overloading is removed and
that use of DEBUG is replaced with a new option OPENSOLARIS_WITNESS.

9d6d5a7131 find: Allow -delete to delete files given as arguments.
Formerly, a command like find dir1/dir2 -delete would delete everything
under dir1/dir2 but not dir1/dir2 itself.

When -L is not specified and "." can be opened, the fts(3) code underlying
find(1) is careful to avoid following symlinks or being dropped in different
locations by moving the directory fts is currently traversing. If a
problematic concurrent modification is detected, fts will not enter the
directory or abort. Files found in the search are returned via the current
working directory and a pathname not containing a slash.

For paranoia, find(1) verifies this when -delete is used. However, it is too
paranoid about the root of the traversal. It is already assumed that the
initial pathname does not refer to directories or symlinks that might be
replaced by untrusted users; otherwise, the whole traversal would be unsafe.
Therefore, it is not necessary to do the check for fts_level ==
FTS_ROOTLEVEL.

Deleting the pathnames given as arguments can be prevented without error
messages using -mindepth 1 or by changing directory and passing "." as
argument to find. This works in the old as well as the new version of find.

99ff83da74 Decouple yarrow from random(4) device.
* Make Yarrow an optional kernel component -- enabled by "YARROW_RNG" option.
  The files sha2.c, hash.c, randomdev_soft.c and yarrow.c comprise yarrow.

* random(4) device doesn't really depend on rijndael-*.  Yarrow, however, does.

* Add random_adaptors.[ch] which is basically a store of random_adaptor's.
  random_adaptor is basically an adapter that plugs in to random(4).
  random_adaptor can only be plugged in to random(4) very early in bootup.
  Unplugging random_adaptor from random(4) is not supported, and is probably a
  bad idea anyway, due to potential loss of entropy pools.
  We currently have 3 random_adaptors:
  + yarrow
  + rdrand (ivy.c)
  + nehemeiah

* Remove platform dependent logic from probe.c, and move it into
  corresponding registration routines of each random_adaptor provider.
  probe.c doesn't do anything other than picking a specific random_adaptor
  from a list of registered ones.

* If the kernel doesn't have any random_adaptor adapters present then the
  creation of /dev/random is postponed until next random_adaptor is kldload'ed.

* Fix randomdev_soft.c to refer to its own random_adaptor, instead of a
  system wide one.

8e94193e58 make path matching in devfs rules consistent and sane (and safer)
Before this change path matching had the following features:
- for device nodes the patterns were matched against full path
- in the above case '/' in a path could be matched by a wildcard
- for directories and links only the last component was matched

So, for example, a pattern like 're*' could match the following entries:
- re0 device
- responder/u0 device
- zvol/recpool directory

Although it was possible to work around this behavior (once it was spotted
and understood), it was very confusing and contrary to documentation.

Now we always match a full path for all types of devfs entries (devices,
directories, links) and a '/' has to be matched explicitly.
This behavior follows the shell globbing rules.

This change is originally developed by Jaakko Heinonen.
Many thanks!

46e95f646c 2 years, 10 months, 22 days after the projects/arm_eabi branch was created
make the ARM EABI the default ABI on arm, armeb, armv6 and armv6eb.

This is intended to be the default ABI from now on with the old ABI to be
retired. Because of this all users are strongly suggested to upgrade to the
ARM EABI.

As the two ABIs are incompatible it is unlikely upgrading in place will
work. Users should perform a full backup and either use an external machine
to upgrade, or install to an alternative location on their media. They
should also reinstall all ports or packages when these are available.

The only known issues are:
 - pkg incorrectly detects the ABI. This is fixed upstream, and will a
   patch will be made to the port.
 - GDB can have issues with executables built with clang.

__FreeBSD_version has been bumped.

3a45b4781a Re-enable CTL in GENERIC on i386 and amd64, but turn on the CTL disable
tunable by default.

This will allow GENERIC configurations to boot on small memory boxes, but
not require end users who want to use CTL to recompile their kernel.  They
can simply set kern.cam.ctl.disable=0 in loader.conf.

The eventual solution to the memory usage problem is to change the way
CTL allocates memory to be more configurable, but this should fix things
for small memory situations in the mean time.

UPDATING:		Explain the change in the CTL configuration, and
			how users can enable CTL if they would like to use
			it.

sys/conf/options:	Add a new option, CTL_DISABLE, that prevents CTL
			from initializing.

ctl.c:			If CTL_DISABLE is turned on, don't initialize.

i386/conf/GENERIC,

			option.
