5c4d28f5dc libc: tag the Rune initialization function prototypes visibility as hidden.
It is good practice to export as few symbols as possible from your shared
libraries, so use the GCC visibility attribute in this case, matching what
Apple's libc does.

881e506b36 makefs: sync NetBSD IDs with upstream for changes that we already have
May 22 21:51:39 2011 +0000 (christos):

    From Nathan Whitehorn (nwhitehorn at freebsd dot org):
    Add code to generate bootable ISOs on Powermac and CHRP systems.
    Synthesize some partition maps (APM and MBR, respectively) pointing
    to (a) the whole disk, and (b) relevant El Torito boot images that
    have been added by other code. These partition maps are a little
    bit funny looking, but they seem to work. FreeBSD has been using
    this successfully in their release generation on powerpc, as well
    as generating all non-SPARC install media. SPARC support could
    probably be added as an extension of this patch.

    PR/45285: Martin Matuska: makefs does not properly convert ISO level 1 and 2
    filenames (buffer overflow)

    makefs does not properly verify the maximum filename length in the
    special "." case for both ISO level 1 and ISO level 2 filename
    conversion.  This creates broken images or causes a buffer overflow
    (ISO level 2).

    ISO level 1:
    If a filename contains only dots or up to 8 characters followed by
    dots the 8+3 limit check doesn't work.

    ISO level 2:
    If a filename contains a dot in the first 30 characters and a dot
    on the 30th character, the length limit check doesn't work and the
    buffer is overflowed.

a1acc06f4f Random bit generator (RBG) driver for RPi and RPi2.
Summary:
This driver supports the following methods to trigger gathering random bits from the hardware:
1. interrupt when the FIFO is full (default) fed into the harvest queue
2. callout (when BCM2835_RNG_USE_CALLOUT is defined) every second if hz is less than 100, otherwise hz / 100, feeding the random bits into the harvest queue

If the kernel is booted with verbose enabled, the contents of the registers will be dumped after the RBG is started during the attach routine.

Author: hackagadget_gmail.com (Stephen J. Kiernan)

Test Plan: Built RPI2 kernel and booted on board. Tested the different methods to feed the harvest queue (callout, interrupt) and the interrupt driven approach seems best. However, keeping the other method for people to be able to experiment with.

fe50ba0583 Include makewhatis in ITOOLS when MK_MAN_UTILS is true
Previously it was conditional on MK_MAN. It's possible to build
FreeBSD with man pages but without man page tools. MK_MAN_UTILS
is the conditional used in share/man/Makefile for determining whether
makewhatis is executed at install time, so it is the proper one for
ITOOLS as well.

ed22e564b8 Add named dynamic states support to ipfw(4).
The keep-state, limit and check-state now will have additional argument
flowname. This flowname will be assigned to dynamic rule by keep-state
or limit opcode. And then can be matched by check-state opcode or
O_PROBE_STATE internal opcode. To reduce possible breakage and to maximize
compatibility with old rulesets default flowname introduced.
It will be assigned to the rules when user has omitted state name in
keep-state and check-state opcodes. Also if name is ambiguous (can be
evaluated as rule opcode) it will be replaced to default.

b1b8369114 llvm-libunwind: use conventional (non-Darwin) X86 register numbers
For historical reasons Darwin/i386 has ebp and esp swapped in the
eh_frame register numbering.  That is:

             Darwin      Other
    Reg #    eh_frame    eh_frame    DWARF
    =====    ========    ========    =====
      4        ebp         esp        esp
      5        esp         ebp        ebp

Although the UNW_X86_* constants are not supposed to be coupled to
DWARF / eh_frame numbering they are currently conflated in LLVM
libunwind, and thus we require the non-Darwin numbering.

ffa25bec32 [ath] don't do LDPC, STBC or short-gi for locationing frames.
The 11n duration calculation function in net80211 and the HAL round /up/
the duration calculation for short-gi, so we can't use that.

The 11n duration calculation doesn't know about the extra symbol time
needed for STBC, nor the LDPC encoding duration, so we can't use
that.

This (along with other, local hacks) allow the locationing services to
get down to around 200nS (yes, nanoseconds) of variance when speaking
to a "good" AP.

e9c0137235 g_Ctoc() conversion buffers are smaller than needed up to MB_CUR_MAX - 1
since whole conversion needs a room for (len >= MB_CUR_MAX). It is no
difference when MB_CUR_MAX == 1, but for multi-byte locales last few chars
('\0' and before) may need just one byte, and the rest of MB_CUR_MAX - 1
space becomes unavailable in the MAXPATHLEN-sized buffer, which cause
conversion error on near MAXPATHLEN long pathes.

Increase g_Ctoc() conversion buffers to MB_LEN_MAX - 1.

f4d4982ea6 1) POSIX defines well when GLOB_ABORTED can be returned (only for directory
open/read errors and with GLOB_ERR and gl_errfunc processing), so we can't
blindly return it on any MAXPATHLEN overflow. Even our manpage disagrees
with such GLOB_ABORTED usage. Use GLOB_NOSPACE for that now with errno is
set to 0 as for limits.

2) Return GLOB_NOSPACE when valid ~ expansion can't happens due to
MAXPATHLEN overflow too.

3) POSIX (and our manpage) says, if GLOB_ERR is set, GLOB_ABORTED should
be returned immediatelly, without using gl_errfunc. Implement it now.

This change adds a pr_pid field to prpsinfo (NT_PRSINFO).  Rather than
bumping the prpsinfo version number, note parsers can use the note's

0c3a489325 Break up vm_fault()'s implementation of the read-ahead and delete-behind
optimizations into two distinct pieces.  The first piece consists of the
code that should only be performed once per page fault and requires the map
to be locked.  The second piece consists of the code that should be
performed each time a pager is called on an object in the shadow chain.
(This second piece expects the map to be unlocked.)

Previously, the entire implementation could be executed multiple times.
Moreover, the second and subsequent executions would occur with the map
unlocked.  Usually, the ensuing unsynchronized accesses to the map were
harmless because the map was not changing.  Nonetheless, it was possible for
a use-after-free error to occur, where vm_fault() wrote to a freed map
entry.  This change corrects that problem.
