30787285b5 Since the socket is non-blocking, it is necessary to use select(2) even

671c033623 Remove incorrect __restrict qualifier on several pointers
The typical case was:
static __inline int
convert_ccl(FILE *fp, char * __restrict p, [...])
{
        [...]

        if (p == SUPPRESS_PTR) {
		[...]
	} else {
		[...]
	}

	[...]
}

This qualifier says that the pointer is the only one at that time
pointing to the resource.

Here, clang considers that "p" will never match "SUPPRESS_PTR" and
optimize the if{} block out. This leads to segfaults in programs calling
vfscanf(3) and vfwscanf(3) with just the format string (no arguments
following it).

The following softwares were reported to abort with segmentation fault
and this patch fixes it:
    o  cmake
    o  smartd
    o  devel/ORBit2

dim@ opened an LLVM PR to discuss this clang optimization:

cbd3cbbae0 Fix a bug in *wscanf's handling of non-wide %s, %c, and %[
conversions.  Both the specification and the documentation say the
width is interpreted as the max number of wide characters to read, but
the implementation was interpreting it as the number of bytes to convert.
(See also r105317.)

This change has security implications for any applications that depend
on the buggy behavior, but the impact in practice is probably nil.
Any such application would already be buggy on other platforms that
get the semantics right.  Also, these conversions are rarely used;
%ls, %lc, and %l[ are more appropriate.

d7af8cf14b Previously, vfscanf()'s wide character processing functions were
reading wide characters manually.  With this change, they now use
fgetwc().  To make this work, we use an internal version of fgetwc()
with a few extensions: it takes an mbstate * because non-wide streams
don't have a built-in mbstate, and it indicates the number of bytes
read.

vfscanf() now resembles vfwscanf() more closely.  Minor functional
improvements include working xlocale support in vfscanf(), setting the
stream error indicator on encoding errors, and proper handling of
shift-based encodings.  (Actually, making shift-based encodings work
with non-wide streams is hopeless, but the implementation now matches
the broken specification.)

666d00d34a If the size passed to {,v}s{w,n}printf is larger than INT_MAX+1
(i.e., the return value would overflow), set errno to EOVERFLOW
and return an error.  This improves the chances that buggy
applications -- for instance, ones that pass in a negative integer
as the size due to a bogus calculation -- will fail in safe ways.
Returning an error in these situations is specified by POSIX, but
POSIX appears to have an off-by-one error that isn't duplicated in
this change.

Previously, some of these functions would silently cap the size at
INT_MAX+1, and others would exit with an error after writing more
than INT_MAX characters.

d2cc835cb5 After r217375, some startup objects under lib/csu are built in a special
way: first they are compiled to assembly, then some sed'ing is done on
the assembly, and lastly the assembly is compiled to an object file.

This last step is done using ${CC}, and not ${AS}, because when the
compiler is clang, it outputs directives that are too advanced for our
old gas.  So we use clang's integrated assembler instead.  (When the
compiler is gcc, it just calls gas, and nothing is different, except one
extra fork.)

However, in the .s to .o rules in lib/csu/$ARCH/Makefile, I still passed
CFLAGS to the compiler, instead of ACFLAGS, which are specifically for
compiling .s files.

In case you are using '-g' for debug info anywhere in your CFLAGS, it
causes the .s files to already contain debug information in the assembly

019100de26 Back out r233646. Although it fixed most libgeom consumers under 32-bit
compatibility, it broke programs using devstat, under 32-bit compatibility and
not.

It's very difficult to fix the identifiers used by devstat, so this change is
simply being backed out.  Since changes to 3rd-party code seem likely, and may be
necessary to properly fix 32-bit binaries on 64-bit kernel, it would seem better
to make more invasive changes to fix GEOM's problems with 32-bit compatibility in
general.

The right thing to do is to replace all of the use of pointers as opaque
identifiers with a fixed-size (64-bit or even 32-bit should be enough for tracking
unique GEOM elments) field.  That probably maintains source compatibility with
most GEOM consumers, and allows xml2tree to make better assumptions about how to
decode the identifiers.

17ce606321 umtx operation UMTX_OP_MUTEX_WAKE has a side-effect that it accesses
a mutex after a thread has unlocked it, it event writes data to the mutex
memory to clear contention bit, there is a race that other threads
can lock it and unlock it, then destroy it, so it should not write
data to the mutex memory if there isn't any waiter.
The new operation UMTX_OP_MUTEX_WAKE2 try to fix the problem. It
requires thread library to clear the lock word entirely, then
call the WAKE2 operation to check if there is any waiter in kernel,
and try to wake up a thread, if necessary, the contention bit is set again
by the operation. This also mitgates the chance that other threads find
the contention bit and try to enter kernel to compete with each other
to wake up sleeping thread, this is unnecessary. With this change, the
mutex owner is no longer holding the mutex until it reaches a point
where kernel umtx queue is locked, it releases the mutex as soon as
possible.
Performance is improved when the mutex is contensted heavily.  On Intel
i3-2310M, the runtime of a benchmark program is reduced from 26.87 seconds
to 2.39 seconds, it even is better than UMTX_OP_MUTEX_WAKE which is
deprecated now. http://people.freebsd.org/~davidxu/bench/mutex_perf.c

3dce589cb9 Fix 32-bit libgeom consumers run on 64-bit kernels with COMPAT_FREEBSD32.
Kernel pointer values are used as opaque unique identifiers, which are then
used to reconstruct references between various providers, classes, etc., inside
libgeom from the source XML.  Unfortunately, they're converted to pointer-width
integers (in the form of pointers) to do this, and 32-bit userland pointers
cannot hold sensible representations (however opaque) of 64-bit kernel pointers
on all systems.

In the case where the leading bits are zero and 32 distinct bits of pointer can
be identified, this will happen to work.  On systems where the upper 32-bits of
kernel pointers are non-zero and the same for all kernel pointers, this will
result in double frees and all kinds of bizarre crashes and linkage between
objects inside libgeom.

To mitigate this problem, treat the opaque identifiers in the XML as C strings
instead, and internalize them to give unique and consistent per-object pointer
values in userland for each identifier in the XML.  This allows us to keep the
libgeom logic the same with only minor changes to initial setup and parsing.

It might be more sensible for speed reasons to treat the identifiers as numbers
of a large size (uintmax_t, say) rather than strings, but strings seem fine for
now.

(As an added side-effect, this makes it slightly easier to identify unresolved
 references, but nothing has been added to inform the user of those.)

7e3d5c1fca Use program exit status as pam_exec return code (optional)
pam_exec(8) now accepts a new option "return_prog_exit_status". When
set, the program exit status is used as the pam_exec return code. It
allows the program to tell why the step failed (eg. user unknown).
However, if it exits with a code not allowed by the calling PAM service
module function (see $PAM_SM_FUNC below), a warning is logged and
PAM_SERVICE_ERR is returned.

The following changes are related to this new feature but they apply no
matter if the "return_prog_exit_status" option is set or not.

The environment passed to the program is extended:
    o  $PAM_SM_FUNC contains the name of the PAM service module function
       (eg. pam_sm_authenticate).
    o  All valid PAM return codes' numerical values are available
       through variables named after the return code name. For instance,
       $PAM_SUCCESS, $PAM_USER_UNKNOWN or $PAM_PERM_DENIED.

pam_exec return code better reflects what went on:
    o  If the program exits with !0, the return code is now
       PAM_PERM_DENIED, not PAM_SYSTEM_ERR.
    o  If the program fails because of a signal (WIFSIGNALED) or doesn't
       terminate normally (!WIFEXITED), the return code is now
       PAM_SERVICE_ERR, not PAM_SYSTEM_ERR.
    o  If a syscall in pam_exec fails, the return code remains
       PAM_SYSTEM_ERR.

waitpid(2) is called in a loop. If it returns because of EINTR, do it
again. Before, it would return PAM_SYSTEM_ERR without waiting for the
child to exit.

Several log messages now include the PAM service module function name.

The man page is updated accordingly.

    and other user kerberos operations. klist and kswitch are just symlinks
    to kcc(1) now.
  o kswitch(1) allows you to easily switch between kerberos credentials if
    you're running KCM.
  o hxtool(1) is a certificate management tool to use with PKINIT.
  o string2key(1) maps a password into key.
  o kdigest(8) is a userland tool to access the KDC's digest interface.
  o kimpersonate(8) creates a "fake" ticket for a service.

  We also now install manpages for some lirbaries that were not installed
  before, libheimntlm and libhx509.

- The new HEIMDAL version no longer supports Kerberos 4.  All users are
  recommended to switch to Kerberos 5.

- Weak ciphers are now disabled by default.  To enable DES support (used
  by telnet(8)), use "allow_weak_crypto" option in krb5.conf.

- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings
  disabled due to the function they use (krb5_get_err_text(3)) being
  deprecated.  I plan to work on this next.

- Heimdal's KDC now require sqlite to operate.  We use the bundled version
  and install it as libheimsqlite.  If some other FreeBSD components will
  require it in the future we can rename it to libbsdsqlite and use for these
  components as well.

- This is not a latest Heimdal version, the new one was released while I was
  working on the update.  I will update it to 1.5.2 soon, as it fixes some
  important bugs and security issues.

1b008f5e51 Some software think a mutex can be destroyed after it owned it, for
example, it uses a serialization point like following:
	pthread_mutex_lock(&mutex);
	pthread_mutex_unlock(&mutex);
	pthread_mutex_destroy(&muetx);
They think a previous lock holder should have already left the mutex and
is no longer referencing it, so they destroy it. To be maximum compatible
with such code, we use IA64 version to unlock the mutex in kernel, remove
the two steps unlocking code.

e5fb99b712 Removed excessive _seekdir() call in closedir(). This saves one lseek()
syscall.  Before r5958, seekdir() was called for its side effect of
freeing memory allocated by opendir() for rewinddir(), but that revision
added _reclaim_telldir() that frees all memory allocated by telldir()
calls, making this call redundant.

This introduces a slight change.  If an application duplicated the descriptor
obtained through dirfd(), it can no longer rely on file position to be
reset to the start of file after a call to closedir().  It's believed to
be safe because neither POSIX, nor any other OS I've tested (NetBSD, Linux,
OS X) rewind the file offset pointer on closedir().

df1f1bae9e In revision 231989, we pass a 16-bit clock ID into kernel, however
according to POSIX document, the clock ID may be dynamically allocated,
it unlikely will be in 64K forever. To make it future compatible, we
pack all timeout information into a new structure called _umtx_time, and
use fourth argument as a size indication, a zero means it is old code
using timespec as timeout value, but the new structure also includes flags
and a clock ID, so the size argument is different than before, and it is
non-zero. With this change, it is possible that a thread can sleep
on any supported clock, though current kernel code does not have such a
POSIX clock driver system.

Ignore the NAT_T extension types so we can at least dump the SADB from
the in-base libipsec/setkey without error when NAT_T support is present
in the kernel, though not printing the additional information yet.
However in case there is no NAT_T support in kernel still consider them
to be an error.

71d8432f98 Replace utxrm(8) by utx(8).
At first, I added a utility called utxrm(8) to remove stale entries from
the user accounting database. It seems there are cases in which we need
to perform different operations on the database as well. Simply rename
utxrm(8) to utx(8) and place the old code under the "rm" command.

In addition to "rm", this tool supports "boot" and "shutdown", which are
going to be used by an rc-script which I am going to commit separately.

a8f77c1f66 Set read buffer size to multiple of sizeof(struct futx).
If the utmpx database gets updated while an application is reading it,
there is a chance the reading application processes partially
overwritten entries. To solve this, make sure we always read a multiple
of sizeof(struct futx) at a time.

ca1672da93 Switch getifaddrs(3) to the new API introduced in r231505. Also remove
conditional code parts not used by or applicable to FreeBSD.

The new implementation is supposed to be able to cope with changes to
the 'l' versions of the msghdr structs now used as well as to if_data
allowing future changes without breaking things.

This restores carp(4) config support in HEAD after r231504.

6d076ae8f7 Introduce a new NET_RT_IFLISTL API to query the address list. It works
on extended and extensible structs if_msghdrl and ifa_msghdrl.  This
will allow us to extend both the msghdrl structs and eventually if_data
in the future without breaking the ABI.

Bump __FreeBSD_version to allow ports to more easily detect the new API.

e82cf13bfb Backout changes from r228571. Remove if_data from struct ifa_msghdr again.
While this breaks carp on HEAD temporary, it restores the upgrade path from
stable, and head before 20111215.

e6ad3d22f4 Detect file modification properly by using tv_nsec.
POSIX 2008 standardizes st_mtim, meaning we can simply use nanosecond
precision to detect file modification.
