there's a bootstrap complication in ths respect. Avoid it. Make the
necessary changes to have upgrade_checks work wth bmake anyway.
2. Remove the use of -E. It's not needed in our build because we use ?= for
the respective variables, which means that we'll take the environment
value (if any) anyway.
3. Properly declare phony targets as phony as bmake is a lot smarter (and
thus agressive) about build avoidance.
4. Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
smarter about build avoidance and should not find files we generate in
the source tree. We should not have files in the repository we want to
generate, but this is an easier way to cross this hurdle.
5. Have behavior under bmake the same as it is under make with respect to

that bmake is informed when sub-commands fail.

This fixes a race condition where another thread may fork() before CLOEXEC
is set, unintentionally passing the descriptor to the child process.
This commit only adds O_CLOEXEC flags to open() or openat() calls where no
fcntl(fd, F_SETFD, FD_CLOEXEC) follows. The separate fcntl() call still
leaves a race window so it should be fixed later.
Because fts keeps internal file descriptors open across calls, making such
descriptors close-on-exec helps not only multi-threaded applications but
also single-threaded applications.
In particular, this prevents passing a temporary file descriptor for saving
the current directory to processes created via find -exec.
The attempt to merge changes from the linux libtirpc caused

For some reason, libc exports the symbol .cerror (HIDENAME(cerror)), albeit
in the FBSDprivate_1.0 version. It looks like there is no reason for this
since it is not used from other libraries. Given that it cannot be accessed
from C and its strange calling convention, it is rather unlikely that other
things rely on it. Perhaps it is from a time when symbols could not be
hidden.
Most of the amd64 assembler code jumps to .cerror using the GOT. It can jump
to it directly now, as in non-PIC mode.
There are also some minor size optimizations to instructions but they yield
virtually no benefit in the size of libc.so.7 due to padding.

Not exporting .cerror causes it to be jumped to directly instead of via the
PLT.
This change also takes advantage of .cerror's new status by not saving and
loading %ebx before jumping to it. (Therefore, .cerror now saves and loads
%ebx itself.) Where there was a conditional jump to a jump to .cerror, the
conditional jump has been changed to jump to .cerror directly (many modern
CPUs don't do static prediction and in any case it is not much of a benefit
anyway).

rpcbind generally ignores the r_owner field for calls that come in over

When building libelf in the bootstrap stage this would include the tree
versions of, for example, sys/_types.h. This would work as long as the
tree's version of this file was close enough to the system's version of
the file. If, however, there was a change in the tree such that the location
of a typedef was moved this would cause problems. In this case the version
of sys/_types.h in the tree no longer defines __wchar_t and expects it to
to be defined in machine/_types.h, however we pick up machine/_types.h from
the system and find it is not defined there. The solution is to restrict the
parts of sys er include from the tree to those that are needed.

clock_gettime(2) functions if supported. The speedup seen in
microbenchmarks is in range 4x-7x depending on the hardware.
Only amd64 and i386 architectures are supported. Libc uses rdtsc and
kernel data to calculate current time, if enabled by kernel.
Hopefully, this code is going to migrate into vdso in some future.

First, extend the changes in r230782 to better handle the common case
of using NOREUSE with sequential reads. A NOREUSE file descriptor
will now track the last implicit DONTNEED request it made as a result
of a NOREUSE read. If a subsequent NOREUSE read is adjacent to the
previous range, it will apply the DONTNEED request to the entire range
of both the previous read and the current read. The effect is that
each read of a file accessed sequentially will apply the DONTNEED
request to the entire range that has been read. This allows NOREUSE
to properly handle misaligned reads by flushing each buffer to cache
once it has been completely read.
Second, apply the same changes made to read(2) by r230782 and this
change to writes. This provides much better performance in the
sequential write case as it allows writes to still be clustered. It
also provides much better performance for misaligned writes. It does
mean that NOREUSE will be generally ineffective for non-sequential
writes as the current implementation relies on a future NOREUSE
write's implicit DONTNEED request to flush the dirty buffer from the
current write.

string buffer for each linelist l_line into one large string. Since
linelists parsed out during the previous passes store the pointers to
previously allocated l_lines, the reallocation caused undefined
behaviour on accessing the buffers, and quite deterministic fault on
freeing them (in mountd(8) startup).
This fixes reading of netgroup(5) file which contains more then one
netgroup.

which was inadvertently caused by r236185: if SHLIBDIR is set using the
?= operator, it must be done *before* bsd.own.mk is included, otherwise
the default value is still used.
Note, bsd.lib.mk will take care of removing the copy in /usr/lib upon
installation, so no addition to ObsoleteFiles.inc is needed.

thing it was still used for was to set the "global default" password
hash. Since the stock auth.conf contained nothing but comments, the
global default was actually the first algorithm in crypt(3)'s list,
which happens to be DES; I take the fact that nobody noticed as proof
that it was not used outside of crypt(3).
The only other use in our tree was in the Kerberos support code in
in tinyware's passwd(1). I removed that code in an earlier commit;
it would not have compiled anyway, as it only supported Kerberos IV.
The auth_getval() function is now a stub that always returns NULL,
which has the same effect as a functional auth_getval() with an
empty auth.conf.

- Use CLOCK_MONOTONIC instead of CLOCK_REALTIME, because CLOCK_MONOTONIC
does not wrap into negative in near future. This fixes any potential
problems using "pthread_cond_timedwait()".
- Fix a bug where the "libusb_wait_for_event()" function computes an
absolute timeout instead of a relative timeout. USB transfers do
not depend on this timeout value.
- Add dependency towards LibPthread to Makefile, because LibUSB v1.0
needs this library to function correctly.

(Resolved state) recommend this way for the current standard (called
"earlier" in the text)
"However, earlier versions of this standard did not require this, and the
same example had to be written as:
// buf was obtained by malloc(buflen)
ret = write(fd, buf, buflen);
if (ret < 0) {
int save = errno;
free(buf);
errno = save;
return ret;
}
"
from feedback I have for previous commit it seems that many people prefer
to avoid mass code change needed for current standard compliance
and prefer to track unpublished standard instead, which requires now
that free() itself must save errno, not its usage code.
So, I back out "save errno across free()" part of previous commit,
and will fill PR for changing free() isntead.
2) Remove now unused serrno.
MFC after: 1 week
"The setting of errno after a successful call to a function is
unspecified unless the description of that function specifies that
errno shall not be modified."
However, free() in IEEE Std 1003.1-2008 does not mention its interaction
with errno, so MAY modify it after successful call
(it depends on particular free() implementation, OS-specific, etc.).
So, save errno across free() calls to make code portable and
POSIX-conformant.
2) Remove unused serrno assignment.
