ace66b568e Implement soft pressure on UMA cache bucket sizes.
Every time system detects low memory condition decrease bucket sizes for
each zone by one item.  As result, higher memory pressure will push to
smaller bucket sizes and so smaller per-CPU caches and so more efficient
memory use.

Before this change there was no force to oppose buckets growth as result
of practically inevitable zone lock conflicts, and after some run time
per-CPU caches could consume enough RAM to kill the system.

204957ef5e Bug fixes in iconv(3) UTF-7 support.
- Add ' to the list of directly encoded characters and * to the list of
  optionally directly encoded characters as per RFC 2152.

- In _citrus_UTF7_mbtoutf16 on end of input when the next output character
  has only been partially decoded, save a copy of the buffer of input
  characters (not just its length).  On the next call with more input
  characters this buffer is reprocessed together with the new input to
  form a fully decoded output character.

- At the end of a base64 encoded sequence fully discard '-' (BASE64_OUT)
  by decrementing psenc->chlen and i.  This is needed to make room in
  psenc->ch (input buffer) in case the next input character starts a new
  base64 encoded sequence.  And also, if this is the end of input and no
  output character can be returned, this brings the encoder in the initial
  state as indicated by _citrus_UTF7_stdenc_get_state_desc_generic which
  is used by the caller to distinguish between no output and partial
  output.

- In _citrus_UTF7_mbrtowc_priv pass the s parameter (input pointer)
  directly to _citrus_UTF7_mbtoutf16 instead of a copy (s0).  This way s
  is updated correctly in case of errors.

- In _citrus_UTF7_mbrtowc_priv when called with psenc->surrogate set
  (previous call did not have enough input), retrieve the previously
  decoded UTF-16 character from (psenc->cache >> psenc->bits) instead of
  (psenc->cache >> 2).

1f9e80bcdb opensolaris/uts/common/dtrace/fasttrap.c
Fix several problems that can cause panics on kldload and kldunload.

	* kproc_create(fasttrap_pid_cleanup_cb, ...) gets called before
	  fasttrap_provs.fth_table gets allocated.  This can lead to a panic
	  on module load, because fasttrap_pid_cleanup_cb references
	  fasttrap_provs.fth_table.  Move kproc_create down after the point
	  that fasttrap_provs.fth_table gets allocated, and modify the error
	  handling accordingly.

	* dtrace_fasttrap_{fork,exec,exit} weren't getting NULLed until
	  after fasttrap_provs.fth_table got freed.  That caused panics on
	  module unload because fasttrap_exec_exit calls
	  fasttrap_provider_retire, which references
	  fasttrap_provs.fth_table.  NULL those function pointers earlier.

	* There wasn't any code to destroy the
	  fasttrap_{tpoints,provs,procs}.fth_table mutexes on module unload,
	  leading to a resource leak when WITNESS is enabled.  Destroy those
	  mutexes during fasttrap_unload().

dc2445625a Add the 'dvd1.iso' target. This mimics the 'release.iso' target,
with the additional step of fetching packages for inclusion on the
dvd image.

The 'pkg-stage' target is used to run 'scripts/pkg-stage.sh' if
the '${TARGET}/pkg-stage.conf' configuration file exists (currently
only amd64 and i386).

Allow dvd1.iso to be skipped if NODVD=1.

042a51f641 Add a script and configuration files to fetch pre-built packages
from pkg.FreeBSD.org for inclusion on release medium (dvd1.iso).

The script sources ${.CURDIR}/${TARGET}/pkg-stage.conf, which sets
several environment variables, such as the pkg(8) ABI, PACKAGESITE,
PKG_DBDIR, and PKG_CACHEDIR.  PKG_CACHEDIR is set to the directory
on the release medium used by bsdconfig(8) (/packages/${ABI}).  ABI
is determined by output of 'make -C /usr/src/release -V REVISION'.
See pkg.conf(5) for descripton on other variables set here.

The list of packages to include are set within the configuration
file.

The script and configuration files are intended to be run by the
'make dvd' target within the release directory, and assume the
release is built within a chroot environment (such as by using
release.sh).

Relevant updates to release/Makefile will follow.

21203fdd06 Add some sample test programs.
This change adds some sample test cases to share/examples/tests/
demonstrating the basic usage of the atf and plain interfaces.

These test programs are fully-functional and are installed as part
of the test suite, which guarantees that the sample code remains
correct.  However, they currently mostly serve as a placeholder for
additional examples and may be incomplete (depending on how you
look at them).  I will see what else can be useful while working on
documentation.

As a bonus, the addition of these tests exercise the *.test.mk files,
one of which (plain.test.mk) was not yet in use, and also demonstrates
that it's possible to mix different kinds of test programs into the
same test suite.

dd580326fe The fasttrap ioctl used to create probes takes a variable-sized argument.
It was not being correctly copied into the kernel on FreeBSD, and as a
result, probes with multiple probe sites were not being created properly.
To fix this, change the ioctl definition so that the fasttrap ioctl handler
is responsible for copying in userland data.

73cdac7877 Update notes for imports of atf.
This is because the atf vendor branch now includes a verbatim copy of
the distfile sources.  As a result, the list of files to-be-removed from
the contrib/ directory is now more aggressive (and different) and the
upgrade notes now only describe stuff that is specific to the atf import
and is not documented in the Subversion Primer.

615dc002b8 Fix the build of some ATF tests.
When building various programs from a single Makefile, program-specific
variables are of the form <VAR>.<PROG>, not <VAR>_<PROG>.  Fix this
obvious typo to fix the build when WITH_TESTS=yes.

I am not sure how this ever worked before given that manual inspection
of bsd.progs.mk clearly shows that the expected character between the
two components is a dot and not an underscore... but I suspect the
changes in r258095 exposed this oddity.

2b7d2c216d Bump __FreeBSD_version for iconv changes 2013-11-17 22:59:06 +00:00
Peter Wemm
091b8336ae Attempt to move the POSIX iconv* symbols out of runtime linker space.
FreeBSD systems usually implemented this as a third party module and
our implementation hasn't played as nicely with the old way as it could
have.

To that end:
* Rename the iconv* symbols in libc.so.7 to have a __bsd_ prefix.
* Provide .symver compatability with existing 10.x+ binaries that
  referenced the iconv symbols. All existing binaries should work.
* Like on Linux/glibc systems, add a libc_nonshared.a to the ldscript
  at /usr/lib/libc.so.
* Move the "iconv*" wrapper symbols to libc_nonshared.a

This should solve the runtime ambiguity about which symbols resolve
to where.  If you compile against the iconv in libc, your runtime
dependencies will be unambiguous.

Old 9.x libraries and binaries will always resolve against their
libiconv.so.3 like they did on 9.x.  They won't resolve against libc.

Old 10.x binaries will be satisified by the .symver helpers.

This should allow ports to selectively compile against the libiconv
port if needed and it should behave without ambiguity now.

b20a9aa92a Fix siginfo_t.si_status for wait6/waitid/SIGCHLD.
Per POSIX, si_status should contain the value passed to exit() for
si_code==CLD_EXITED and the signal number for other si_code. This was
incorrect for CLD_EXITED and CLD_DUMPED.

This is still not fully POSIX-compliant (Austin group issue #594 says that
the full value passed to exit() shall be returned via si_status, not just
the low 8 bits) but is sufficient for a si_status-related test in libnih
(upstart, Debian/kFreeBSD).

776fd11e30 Add a sysctl to allow disabling resetting the OF syscons.
On some machines (G5 with lots of RAM), entering OF sometimes causes the
machine to hang.  Once the machine is booted, currently the only entry point
into OF is through resetting the framebuffer on mode switch on these machines.
Disabling this allows the machine to stay up at the expense of less usable
consoles after X is started.
