process, using pdfork(2). Forking from a process has a lot of advantages:
1. We have the same cwd as the original process.
2. The same uid, gid and groups.
3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper
to new architecture.

bd18fd57db DIRDEPS_BUILD: Regenerate without local dependencies.
These are no longer needed after the recent 'beforebuild: depend' changes
and hooking DIRDEPS_BUILD into a subset of FAST_DEPEND which supports
skipping 'make depend'.

b9cd412e7b FAST_DEPEND: Always run depend via beforebuild which removes many hacks.
This will generate dependencies rather than depending on the previous behavior
of depending on the guessed OBJS: *.h dependecies or a user running
'make depend'.

Experimentation showed that depending only on headers was not enough and
prone to .ORDER errors.  Downstream users may also have added
dependencies into beforedepend or afterdepend targets.  The safest way to
ensure dependencies are generated before build is to run 'make depend'
beforehand rather than just depending on DPSRCS+SRCS.

Note that the OBJS_DEPEND_GUESS mechanism (a.k.a .if !exists(.depend) then
foo.o: *.h) is still useful as it improves incremental builds with missing
.depend.* files and allows 'make foo.o' to usually work, while this
'beforebuild: depend' ensures that the build will always find all dependencies.
The 'make foo.o' case has no means of a 'beforebuild' hook.

This also removes several hacks in the DIRDEPS_BUILD:
- NO_INSTALL_INCLUDES is no longer needed as it mostly was to work around
  .ORDER problems with building the needed headers early.
- DIRDEPS_BUILD: It is no longer necesarry to track "local dependencies" in
  Makefile.depend.

  These were only in Makefile.depend for 'clean builds' since nothing would
  generate the files due to skipping 'make depend' and early dependency
  bugs that have been fixed, such as adding headers into SRCS for the
  OBJS_DEPEND_GUESS mechanism.  Normally if a .depend file does not exist then
  a dependency is added by bsd.lib.mk/bsd.prog.mk from OBJS: *.h.  However,
  meta.autodep.mk creates a .depend file from created meta files and inserts
  that into Makefile.depend.  It also only tracks *.[ch] files though which can
  miss some dependencies that are hooked into 'make depend'.  This .depend
  that is created then breaks incremental builds due to the !exists(.depend)
  checks for OBJS_DEPEND_GUESS.  The goal was to skip 'make depend' yet it only
  really works the first time.  After that files are not generated as expected,
  which r288966 tried to address but was using buildfiles: rather than
  beforebuild: and was reverted in r291725.  As noted previously,
  depending only on headers in beforebuild: would create .ORDER errors
  in some cases.

  meta.autodep.mk is still used to generate Makefile.depend though via:
    gendirdeps: Makefile.depend
    .END: gendirdeps

  This commit allows removing all of the "local dependencies" in
  Makefile.depend which cuts down on churn and removes some of the
  arch-dependent Makefile.depend files.

  The "local dependencies" were also problematic for bootstrapping.

287b96dd25 Add handling for non-native error values to libsysdecode.
Add two new functions, sysdecode_abi_to_freebsd_errno() and
sysdecode_freebsd_to_abi_errno(), which convert errno values between
the native FreeBSD ABI and other supported ABIs. Note that the
mappings are not necessarily perfect meaning in some cases multiple
errors in one ABI might map to a single error in another ABI. In that
case, the reverse mapping will return one of the errors that maps, but
which error is non-deterministic.

Change truss to always report the raw error value to the user but
use libsysdecode to map it to a native errno value that can be used
with strerror() to generate a description. Previously truss reported
the "converted" error value. Now the user will always see the exact
error value that the application sees.

Change kdump to report the truly raw error value to the user. Previously
kdump would report the absolute value of the raw error value (so for
Linux binaries it didn't output the FreeBSD error value, but the positive
value of the Linux error). Now it reports the real (i.e. negative) error
value for Linux binaries. Also, use libsysdecode to convert the native
FreeBSD error reported in the ktrace record to the raw error used by the
ABI. This means that the Linux ABI can now be handled directly in
ktrsysret() and removes the need for linux_ktrsysret().

08674c4573 Rename pte.h to pte-v4.h and start including directly either pte-v4.h
or pte-v6.h in files which needs it.

There are quite internal definitions in pte-v4.h and pte-v6.h headers
specific for corresponding pmap implementation. These headers should be
included only in very few files and an intention is to not hide for
which implementation such files are.

Further, sys/arm/arm/elf_trampoline.c is an example of file which
uses armv4 like pmap implementation for both armv4 and armv6 platforms.
This is another reason why pte.h which includes specific header
according to __ARM_ARCH is not created.

2082bf26c8 fputs: Return the number of bytes written.
POSIX.1-2008 requires that successful completion simply return a
non-negative integer. We have regularly returned a constant value.
Another, equally valid, implementation convention implies returning
the number of bytes written.

Adopt this last convention to be in line with what Apple's libc
does. POSIX also explicitly notes:

Note that this implementation convention cannot be adhered to for strings
longer than {INT_MAX} bytes as the value would not be representable in the
return type of the function. For backwards-compatibility, implementations
can return the number of bytes for strings of up to {INT_MAX} bytes, and
return {INT_MAX} for all longer strings.

Developers shouldn't depend specifically on either convention but
the change may help port software from Apple.

bd43f0691c If libthr.so is dlopened without RTLD_GLOBAL flag, the libthr symbols
do not participate in the global symbols namespace, but rtld locks are
still replaced and functions are interposed.  In particular,
__pthread_map_stacks_exec is resolved to the libc version.  If a
library is loaded later, which requires adjustment of the stack
protection mode, rtld calls into libc __pthread_map_stacks_exec due to
the symbols scope.  The libc version might recurse into binder and
recursively acquire rtld bind lock, causing the hang.

Make libc __pthread_map_stacks_exec() interposed, which synchronizes

7fd852f860 This seems like a very trivial bug that should have been squashed a long
time ago, but for some reason it was not. Basically, without this change
dlopen(3)'ing an empty .so file would just cause application to dump core
with SIGSEGV.

Make sure the file has enough data for at least the ELF header before
mmap'ing it.

Add a test case to check that dlopen an empty file return an error.

There were a separate discussion as to whether it should be SIGBUS
instead when you try to access region mapped from an empty file,
but it's definitely SIGSEGV now, so if anyone want to check that please
be my guest.

wraps sendmsg(2) and recvmsg(2) into batch send and receive operation.
The goal of this implementation is only to provide API compatibility
with Linux.

The cancellation behaviour of the functions is not quite right, but
due to relative rare use of cancellation it is considered acceptable
comparing with the complexity of the correct implementation.  If
functions are reimplemented as syscalls, the fix would come almost
trivial.  The direct use of the syscall trampolines instead of libc
wrappers for sendmsg(2) and recvmsg(2) is to avoid data loss on
cancellation.

2dd1bdf183 Convert rman to use rman_res_t instead of u_long
Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources.  For
now, this is still compatible with u_long.

This is step one in migrating rman to use uintmax_t for resources instead of
u_long.

Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.

This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

a5f14abfd2 Add support to libsysdecode for decoding system call names.
A new sysdecode_syscallname() function accepts a system call code and
returns a string of the corresponding name (or NULL if the code is
unknown).  To support different process ABIs, the new function accepts a
value from a new sysdecode_abi enum as its first argument to select the
ABI in use.  Current ABIs supported include FREEBSD (native binaries),
FREEBSD32, LINUX, LINUX32, and CLOUDABI64.  Note that not all ABIs are
supported by all platforms.  In general, a given ABI is only supported
if a platform can execute binaries for that ABI.

To simplify the implementation, libsysdecode's build reuses the
existing pre-generated files from the kernel source tree rather than
duplicating new copies of said files during the build.

kdump(1) and truss(1) now use these functions to map system call
identifiers to names.  For kdump(1), a new 'syscallname()' function
consolidates duplicated code from ktrsyscall() and ktrsyscallret().
The Linux ABI no longer requires custom handling for ktrsyscall() and
linux_ktrsyscall() has been removed as a result.

88d74d64d7 Restore flushing of output for revoke(2) again. Document revoke()'s
intended behaviour in its man page.  Simplify tty_drain() to match.
Don't call ttydevsw methods in tty_flush() if the device is gone
since we now sometimes call it then.

The flushing was supposed to be implemented by passing the FNONBLOCK
flag to VOP_CLOSE() for revoke().  The tty driver is one of the few
that can block in close and was one of the fewer that knew about this.

This almost worked in FreeBSD-1 and similarly in Net/2.  These
versions only almost worked because there was and is considerable
confusion between IO_NDELAY and FNONBLOCK (aka O_NONBLOCK).  IO_NDELAY
is only valid for VOP_READ() and VOP_WRITE().  For other VOPs it has
the same value as O_SHLOCK.  But since vfs_subr.c and tty.c
consistently used the wrong flag and the O_SHLOCK flag is rarely set,
this mostly worked.  It also gave the feature than applications could
get the non-blocking close by abusing O_SHLOCK.

This was first broken then fixed in 1995.  I changed only the tty
driver to use FNONBLOCK, as a hack to get non-blocking via the normal
flag FNONBLOCK for last closes.  I didn't know about revoke()'s use
of IO_NDELAY or change it to be consistent, so revoke() was broken.
Then I changed revoke() to match.

This was next broken in 1997 then fixed in 1998.  Importing Lite2 made
the flags inconsistent again by undoing the fix only in vfs_subr.c.

This was next broken in 2008 by replacing everything in tty.c and not
checking any flags in last close.  Other bugs in draining limited the
resulting unbounded waits to drain in some cases.

It is now possible to fix this better using the new FREVOKE flag.
Just restore flushing for revoke() for now.  Don't restore or undo any
hacks for ordinary last closes yet.  But remove dead code in the
1-second relative timeout (r272789).  This did extra work to extend
the buggy draining for revoke() for as long as possible.  The 1-second
timeout made this not very long by usually flushing after 1 second.

18a2ccd22d Fix bug in the readpassphrase(3) function, which can be exposed
by application closing its stdin (i.e. STDIN_FILENO) prior to
calling readpassphrase WITHOUT setting RPP_STDIN. What happens
then is that the readpassphrase would open /dev/tty, and since
file descriptors are reused, the call would return first unused
fd, which is 0 which is also STDIN_FILENO. Then due to the usage
of "input != STDIN_FILENO" in the code to do its logic, that
would result in noecho flags not set on that file descriptor,
which was original issue I've been trying to fix.

In addition to that, the readpassphrase() would leak file
descriptor on its way out, so fix that one as well.

This problem can be tested with:

 $ ssh-add - < /tmp/myprivate.key

The password will not be hidden as it should and ktrace will
show:

 53326 ssh-add  CALL  open(0x80142443c,0x100002<O_RDWR|O_CLOEXEC>,<unused>0x165f030)
 53326 ssh-add  NAMI  "/dev/tty"
 53326 ssh-add  RET   open 0
 53326 ssh-add  CALL  sigprocmask(SIG_SETMASK,0x802eb1324,0x7fffffffd5e0)
 53326 ssh-add  RET   sigprocmask 0
 53326 ssh-add  CALL  sigaction(SIGALRM,0x7fffffffd630,0x7fffffffd610)

Instead of:

 57690 ssh-add  CALL  open(0x80142443c,0x100002<O_RDWR|O_CLOEXEC>,<unused>0x165f030)
 57690 ssh-add  NAMI  "/dev/tty"
 57690 ssh-add  RET   open 4
 57690 ssh-add  CALL  ioctl(0x4,TIOCGETA,0x7fffffffd860)
 57690 ssh-add  RET   ioctl 0
 57690 ssh-add  CALL  ioctl(0x4,TIOCSETAF,0x7fffffffd680)
 57690 ssh-add  RET   ioctl 0
 57690 ssh-add  CALL  sigprocmask(SIG_SETMASK,0x802eb1324,0x7fffffffd620)
 57690 ssh-add  RET   sigprocmask 0
 57690 ssh-add  CALL  sigaction(SIGALRM,0x7fffffffd670,0x7fffffffd650)

For the case when the key is read from the file.

Technically this can also be workaround'ed at the application side
by not closing the STDIN_FILENO in the first place, but readpassphrase(3)
doesn't need to make any assumptions about that. Plus the file descriptor
leak confirms that this is an oversight, rather than a deliberate behaviour.

f16550ad09 Test for /etc/ssl/cert.pem existence to avoid masking SSL_CA_CERT_PATH
Prior to this patch, unless SSL_CA_CERT_FILE is set in the environment,
libfetch will set the CA file to "/usr/local/etc/cert.pem" if it exists,
and to "/etc/ssl/cert.pem" otherwise. This has the consequence of
masking SSL_CA_CERT_PATH, because OpenSSL will ignore the CA path if a CA
file is set but fails to load (see X509_STORE_load_locations()).

While here, fall back to OpenSSL defaults if neither SSL_CA_CERT_FILE nor
SSL_CA_CERT_PATH are set in the environment, and if neither of the
libfetch default CA files exists.

In the event that the getconfig(3) call in svcunix_create is partly successful,
some of the netconfig(3) resources allocated might be leaked if the call returns
NULL as endnetconfig(3) wasn't called explicitly in that case. Ensure that the
resources are fully cleaned up by going to the `done` label, which will call
endnetconfig(3) for us.

2bab0c5535 New sendfile(2) syscall. A joint effort of NGINX and Netflix from 2013 and
up to now.

The new sendfile is the code that Netflix uses to send their multiple tens
of gigabits of data per second. The new implementation features asynchronous
I/O, when I/O operations are launched, but not awaited to be complete. An
explanation of why such behavior is beneficial compared to old one is
going to be too long for a commit message, so we will skip it here.

Additional features of new syscall are extra flags, which provide an
application more control over data sent. The SF_NOCACHE flag tells
kernel that data shouldn't be cached after it was sent. The SF_READAHEAD()
macro allows to specify readahead size in pages.

The new syscalls is a drop in replacement. No modifications are required
to applications. One can take nginx binary for stable/10 and run it
successfully on head. Although SF_NODISKIO lost its original sense, as now
sendfile doesn't block, and now means something completely different (tm),
using the new sendfile the old way is absolutely safe.

fdd1590a42 As submitted upstream in a review, avoid using undefined behavior in
llvm's LinkAllPasses.h.  This caused some of the calls not to be
emitted, if the optimization level was -O2 or higher.

Conversely, if you used -O1 or lower, calls to e.g.  RunningOnValgrind()
would be emitted, leading to link failures, because we did not include
Valgrind.cpp into libllvmsupport.  Therefore, add it unconditionally.
