4d871c1e61 Not all targets support by clang have a tested or enabled ubsan yet.
Only enable h_raw on x86 targets for today so that a buildworld runs to
completion for clang enabled targets that are not x86.  This should be
removed when validation of the sanitizer has occured for all targets
supported by FreeBSD and clang.

d8a7885b36 Fix several memory leaks, and crashes, in iconvlist(3).
- Both curitem and curitem (via the names list) was always leaked.
- malloc(3) failures lead to some leaks.
- __bsd___iconv_get_list() failure lead to a crash since its error was not
  handles and __bsd___iconv_free_list() is not NULL-safe.

I have slightly refactored this to avoid extra malloc and free logic in cases
of malloc(3) failing.

There are still bad assumptions here that I did not deal with.  One of which is
that the data will always have a '/' so the strchr(3) will not return NULL.

f1d04a2543 libedit: Use correct buffer lengths in vi mode v command.
Libedit's vi mode provides a v command to edit the current line in vi(1)
(hard-coded to vi, in fact).

When Unicode/wide character mode was added, this command started truncating
and/or corrupting the edited text.

This commit fixes v if the text fits into the buffer. If the text is longer,
it is truncated.

3e973f9b6d Fix compiling with gcc [4.2.1] after r287797 when MK_HESOID == no and
MK_NIS == no by converting `i` back to an int, and instead cast the loop
comparison to `int`

The loop comparison is iterating the len(ns_dtab)-1, because
the last element is the sentinel tuple { NULL, NULL, NULL, }, so when
both HESOID and NIS are off, len(ns_dtab)-1 == 1 - 1 == 0, and the loop
is skipped because the expression is tautologically false

While here, convert `(sizeof(x) / sizeof(x[0]))` to `nitems(x)`

Tested with: clang 3.7.0, gcc 4.2.1, and gcc 4.9.4 [*] with MK_NIS={no,yes}
             and by running bash -lc 'id -u && id -g && id'

* gcc 4.9.4 needs another patch in order for the compile to succeed
  with -Werror with lib/libc/gen/getgrent.c

4cf0f1f5b3 resolver: abuse _res a little less
In the past, _res was a global variable.  Now, it's multiple function calls.
Several functions in the resolver use _res multiple times and therefore
call the function(s) far more than necessary.

Fix those callers to store the result of _res in a local variable.

Add __noinline to the definition of res_init() to avoid the code bloat
that these changes would have otherwise incurred.  Thanks to jilles
for noticing this.

60b27ebb25 resolver: automatically reload /etc/resolv.conf
On each resolver query, use stat(2) to see if the modification time
of /etc/resolv.conf has changed.  If so, reload the file and reinitialize
the resolver library.  However, only call stat(2) if at least two seconds
have passed since the last call to stat(2), since calling it on every
query could kill performance.

This new behavior is enabled by default.  Add a "reload-period" option
to disable it or change the period of the test.

Document this behavior and option in resolv.conf(5).

Polish the man page just enough to appease igor.

59e2ff550c Integrate the tests from lib/libarchive, usr.bin/cpio, and usr.bin/tar in to
the FreeBSD test suite

functional_test.sh was ported from bin/sh/tests/functional_test.sh, as a
small wrapper around libarchive_test, bsdcpio_test, and bsdtar_test provided
by upstream.

A handful of testcases in lib/libarchive/tests have been disabled as they
were failing when run with kyua test (see BROKEN_TESTS in
lib/libarchive/tests/Makefile)

As a sidenote: this removes the check/test targets from the Makefiles as they
don't match the pattern used in the rest of the FreeBSD test suite.

92001b9497 Change the default setting of kern.ipc.shm_allow_removed from 0 to 1.
This removes the need for manually changing this flag for Google Chrome
users. It also improves compatibility with Linux applications running under
Linuxulator compatibility layer, and possibly also helps in porting software
from Linux.

Generally speaking, the flag allows applications to create the shared memory
segment, attach it, remove it, and then continue to use it and to reattach it
later. This means that the kernel will automatically "clean up" after the
application exits.

It could be argued that it's against POSIX. However, SUSv3 says this
about IPC_RMID: "Remove the shared memory identifier specified by shmid from
the system and destroy the shared memory segment and shmid_ds data structure
associated with it." From my reading, we break it in any case by deferring
removal of the segment until it's detached; we won't break it any more
by also deferring removal of the identifier.

This is the behaviour exhibited by Linux since... probably always, and
also by OpenBSD since the following commit:

revision 1.54
date: 2011/10/27 07:56:28; author: robert; state: Exp; lines: +3 -8;
Allow segments to be used even after they were marked for deletion with
the IPC_RMID flag.
This is permitted as an extension beyond the standards and this is similar
to what other operating systems like linux do.

e6b95927f3 Fix core corruption caused by race in note_procstat_vmmap
This fix is spiritually similar to r287442 and was discovered thanks to
the KASSERT added in that revision.

NT_PROCSTAT_VMMAP output length, when packing kinfo structs, is tied to
the length of filenames corresponding to vnodes in the process' vm map
via vn_fullpath.  As vnodes may move during coredump, this is racy.

We do not remove the race, only prevent it from causing coredump
corruption.

- Add a sysctl, kern.coredump_pack_vmmapinfo, to allow users to disable
  kinfo packing for PROCSTAT_VMMAP notes.  This avoids VMMAP corruption
  and truncation, even if names change, at the cost of up to PATH_MAX
  bytes per mapped object.  The new sysctl is documented in core.5.

- Fix note_procstat_vmmap to self-limit in the second pass.  This
  addresses corruption, at the cost of sometimes producing a truncated
  result.

- Fix PROCSTAT_VMMAP consumers libutil (and libprocstat, via copy-paste)
  to grok the new zero padding.
