- Fix a logic bug which prevented the sending of UDP packet with 0 checksum.
- Disable TX checksum offload for UDP-Lite completely. It wasn't used for
partial checksum coverage, but even for full checksum coverage it doesn't
work.
citrus: Avoid invalid code points.
The UTF-8 decoder should not accept byte sequences which decode to
unicode code positions U+D800 to U+DFFF (UTF-16 surrogates).[1]
Contrary to the original OpenBSD patch, we do pass U+FFFE and U+FFFF,
both values are valid "non-characters" [2] and must be mapped through
UTFs.

- In the libiconv module for ISO 2022 restore the original order of the
fields of a private struct such that variables of this type are
initialised correctly. Fixes conversion from ISO 2022.
Also do this in the BIG5 module to prevent similar errors in the future.
- In the libiconv module for EUC-TW replace 2^cs with 1<<cs. Fixes
conversion from EUC-TW.
- Synchronise iconv code with NetBSD. In most cases this only updates

Merge the projects/clang-sparc64 branch back to head. This brings in
several updates from the llvm and clang trunks to make the sparc64
backend fully functional.
Apart from one patch to sys/sparc64/include/pcpu.h which is still under
discussion, this makes it possible to let clang fully build world and
kernel for sparc64.
Any assistance with testing this on actual sparc64 hardware is greatly
appreciated, as there will unavoidably be bugs left.
Many thanks go to Roman Divacky for his upstream work on getting the
sparc64 backend into shape.
MFC r262985:
Repair a few minor mismerges from r262261 in the clang-sparc64 project
branch. This is also to minimize differences with upstream.

If rare conditions such as concurrent conflicting manipulation of the
filesystem occur, fts_read() frees the current FTSENT without adjusting
the pointers in the FTS accordingly. A later fts_close() then frees the
same FTSENT again.

This fixes some dereferencing bugs in Chinese character set conversions.

The posix_fallocate(2) syscall should return error number on error,
without modifying errno.
MFC r261290:
The posix_madvise(3) and posix_fadvise(2) should return error on
failure, same as posix_fallocate(2).
Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.
Similar to the (1 << 31) case it is not defined to do (2 << 30).
This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.
A similar change was made in OpenBSD.
Fix several bugs in sctp_bindx():
* Set errno to EAFNOSUPPORT if an address is provided which is neither
AF_INET nor AF_INET6.
* Don't modify the arguments.
* Don't smash the stack when provided with a non-zero port.
* Handle the case correctly where the first address provided is
an IPv6 address.
The compile time constant limit on number of swap devices was removed in 5.2.
As such, remove the EINVAL error saying so. Currently the vm.nswapdev sysctl
just represents the number of added swap devices.
Do not force to run atexit handlers, which text comes from a dso owning
the handle passed to __cxa_finalize() but which are registered by other
dso, when the process is inside exit(3).
r258537 (hrs):
Add ICONV_{GET,SET}_ILSEQ_INVALID iconvctl. GNU iconv returns
EILSEQ when there is an invalid character in the output codeset
while it is valid in the input. However, POSIX requires iconv()
to perform an implementation-defined conversion on the character.
So, Citrus iconv converts such a character to a special character
which means it is invalid in the output codeset.
This is not a problem in most cases but some software like libxml2
depends on GNU's behavior to determine if a character is output
as-is or another form such as a character entity (&#NNN;).
r258587 (peter):
Move the iconv wrapper source from libc_nonshared to libc/iconv so
that it is all in the one place again. Rename libc/iconv/iconv.c
to bsd_iconv.c. Compile the wrappers into libc.a so that
WITHOUT_DYNAMICROOT works again.

- Add a new protect(1) command that can be used to set or revoke protection
from arbitrary processes. Similar to ktrace it can apply a change to all
existing descendants of a process as well as future descendants.
- Add a new procctl(2) system call that provides a generic interface for
control operations on processes (as opposed to the debugger-specific
operations provided by ptrace(2)). procctl(2) uses a combination of
idtype_t and an id to identify the set of processes on which to operate
similar to wait6().
- Add a PROC_SPROTECT control operation to manage the protection status
of a set of processes. MADV_PROTECT still works for backwards
compatability.
- Add a p_flag2 to struct proc (and a corresponding ki_flag2 to kinfo_proc)
the first bit of which is used to track if P_PROTECT should be inherited

This change avoids undesirably passing some internal file descriptors to a

Kernel support for SOCK_CLOEXEC was added in r248534, March 19, 2013.
Austin Group issue #411 requires 'e' to be accepted before and after 'x',
and encourages accepting the characters in any order, except the initial
'r', 'w' or 'a'.
Given that glibc accepts the characters after r/w/a in any order and that
diagnosing this problem may be hard, change our libc to behave that way as
well.
