bff207520a libgcc_s: add libm dependencies from div{d,s,x}c3
compiler-rt's complex division support routines contain calls to
compiler builtins such as `__builtin_scalbnl`.  Unfortunately Clang
turns these back into a call to `scalbnl`.

For now link libm's C version of the required support routines.

4ef9bd22ed Improve typing of POSIX search tree functions.
Back in 2015 when I reimplemented these functions to use an AVL tree, I
was annoyed by the weakness of the typing of these functions. Both tree
nodes and keys are represented by 'void *', meaning that things like the
documentation for these functions are an absolute train wreck.

To make things worse, users of these functions need to cast the return
value of tfind()/tsearch() from 'void *' to 'type_of_key **' in order to
access the key. Technically speaking such casts violate aliasing rules.
I've observed actual breakages as a result of this by enabling features
like LTO.

I've filed a bug report at the Austin Group. Looking at the way the bug
got resolved, they made a pretty good step in the right direction. A new
type 'posix_tnode' has been added to correspond to tree nodes. It is
still defined as 'void' for source-level compatibility, but in the very
far future it could be replaced by a proper structure type containing a
key pointer.

d49a5ddd04 Create libefivar library. This library aims to provide
the same API as the GPL'd version of this library. It implements the common
Linux API for programatically manipulating UEFI environment varibales using
the UEFI Runtime Services the kernel provides. It replaces the old efi
library since it is programmed to a different interface, but retails the
CHAR16 to UTF-8 and vice versa conversion routines. The new name is to match
Linux program's expectations.

7e81ad1292 abort in srandomdev if kern.arandom sysctl fails
The sysctl cannot fail. If it does fail on some FreeBSD derivative or
after some future change, just abort() so that the problem will be found
and fixed.

While abort() is not normally suitable for a library, it makes sense
here.

This is akin to r306636 for arc4random.

1a466ddc79 Remove setkey(), encrypt(), des_setkey() and des_cipher().
The setkey() and encrypt() functions are part of XSI, not the POSIX base
definitions. There is no strict requirement for us to provide these,
especially if we're only going to keep these around as undocumented
stubs. The same holds for des_setkey() and des_cipher().

Instead of providing functions that only generate warnings when linking,
simply disallow linking against them. The impact of this is relatively
low. It only causes two leaf ports to break. I'll see what I can do to
help out to get those fixed.

35c05a4fbc Add librss, a simple wrapper around RSS APIs so applications can begin auto-tuning.
I've used this in a handful of RSS test applications.  It is just some
very simple functions to fetch the RSS configuration, query the per-bucket
CPU set, and mark sockets as local to an RSS bucket.  It should be sufficient
for both thread-based and process-based workloads.

(Yes, I wrote a manpage.)

This is based on some early RSS API and wrapper API work I did whilst
I was at Netflix.  Thanks to Netflix for the very original work that
spawned this; thanks to Peter Grehan for his feedback about RSS APIs
and thanks to Jack Vogel and Navdeep Parhar for the NIC-facing side of the
APIs.  These fed into the simple userland API I wrote up here.

fd85bff53e Replace dirname(3) by a copy that complies to POSIX.
It turns out that the path normalization that our brand new copy of
dirname(3) does is actually not allowed by the draft version of the
upcoming version of POSIX. It has to behave identically to the
dirname(1) utility.

This change replaces our new dirname(3) implementation by yet another
version that doesn't implement the path normalization logic; it merely
looks for the end of the directory name and overwrites that with a null
byte.

5432c3bec3 Disconnect the "optimized" asm variants of cos(), sin() and tan() from
the build on i386.  Leave them in the source tree for regression tests.

The asm functions were always much less accurate (by a factor of more
than 10**18 in the worst case).  They were faster on old CPUs.  But
with each new generation of CPUs they get relatively slower.  The
double precision C version's average advantage is about a factor of 2
on Haswell.

The asm functions were already intentionally avoided in float and long
double precision on i386 and in all precisions on amd64.  Float
precision and amd64 give larger advantages to the C version.  The long
double precision C code and compilers' understanding of long double
precision are not so good, so the i387 is still slightly faster for
long double precision, except for the unimportant subcase of huge args
where the sub-optimal C code now somehow beats the i387 by about a
factor of 2.

mixture of all 6 variants of remainder in asm and only 1 of 6
variants of fmod in asm.

eab5e7a376 Don't bake all of CC/CPP/CXX into CFLAGS
Capture executable names for CC, CPP, CXX (assumed to be the
first non-CCACHE_BIN word).

This change strips out all of the cross-compiler arguments, (-target,
-B, etc), added to ${CC}, etc via ${CROSSENV} in Makefile.inc1, so it
doesn't infect the build and subsequently the test.

Add comments noting why this logic is being added, and why the logic in
r305041 was necessary/what it was trying to achieve.

This is required after recent changes made to the toolchain to always
specify --sysroot, -target, -B, etc with clang in buildworld (presumably
r304681).

89688ae708 directory(3): Deprecate readdir_r(). Clarify dirent buffers.
In existing implementations including FreeBSD, there is no reason to use
readdir_r() in the common case where potentially multiple threads each list
their own directory. Code using readdir() is simpler.

What's more, lthough readdir_r() can safely be used on FreeBSD because
NAME_MAX is forced to 255, it cannot be used safely on systems where
{NAME_MAX} is not fixed. As a concrete example, FAT/NTFS filenames can be up
to 255 UTF-16 code units long, which can be up to 765 UTF-8 bytes.

Deprecating readdir_r() in POSIX has been proposed in
http://www.austingroupbugs.net/view.php?id=696
and glibc wants to deprecate it as well.

6a695123b0 Netboot: allow both tftpfs and nfs in both pxeboot and loader.efi
Add a new 'netproto' variable which can be set for now to
NET_TFTP or NET_NFS (default to NET_NONE)

From the dhcp options if one sets the root-path option to:
"ip:path", the loader will consider it is booting over NFS
(meaning same behaviour as the default current behaviour)

if the dhcp option "tftp server address" is set (option 150)
the loader will consider it is booting over tftpfs, it will then
consider the root-path options with 2 possible case
1. "path" then the IP of the tftp server will be the one passed by
the option 150, and the files will be retrieved under "path" on the tftp
server
2. "ip:path" then the IP of the tftp server will be the one passed in
the option "overwritting the IP from the option 150.

We could not "abuse" the rootpath option in the form or tftp://ip:path because
this is already used for other purpose by iPXE preventing any chainload from
iPXE to the FreeBSD loader.

Given at each open(), the loader loops over all available filesystems and keep
the "best" error, we needed to prevent tftpfs to fallback on nfs and vice versa.
the tftpfs and nfs implementation in libstand now return EINVAL early if
'netproto' for that purpose.

da6e468936 Do not obliterate errno value in the main thread during ptrace(2) call on x86.
Since ptrace(2) syscall can return -1 for non-error situations, libc
wrappers set errno to 0 before performing the syscall, as the service
to the caller.  On both i386 and amd64, the errno symbol was directly
referenced, which only works correctly in single-threaded process.

Change assembler wrappers for ptrace(2) to get current thread errno
location by calling __error().  Allow __error interposing, as
currently allowed in cerror().

ebbc445889 The formal behavior of qsort is unstable with regard to objects that
are equal. Unfortunately, RFC 3484 requires that otherwise equal objects
remain in the order supplied by the DNS server. The present code attempts
to deal with this by returning -1 for objects that are equal (i.e.,
returns that the first parameter is less then the second parameter).
Unfortunately, the qsort API does not state that the first parameter
passed in is in any particular position in the list.

986e05bc2a Completely revamp the way llvm, clang and lldb are built.
* Bootstrap llvm-tblgen and clang-tblgen with a minimal llvm static
  library, that has no other dependencies.
* Roll up all separate llvm libraries into one big static libllvm.
* Similar for all separate clang and lldb static libraries.
* For all these libraries, generate their .inc files only once.
* Link all llvm tools (including extra) against the big libllvm.
* Link clang and clang-format against the big libllvm and libclang.
* Link lldb against the big libllvm, libclang and liblldb.

N.B.: This is work in progress, some details may still be missing.

It also heavily depends on bsd.*.mk's support for SRCS and DPSRCS with
relative pathnames, which apparently does not always work as expected.
For building llvm, clang and lldb though, it seems to work just fine.

The main idea behind this restructuring is maintainability and build
peformance.  The previous large number of very small libraries, each
with their own generated files and dependencies was slow to traverse
and hard to understand.

Possible future improvements:
* Only build certain targets, e.g. for most regular users having just
  one target will be fine.  This will shave off some build time.
* Building the big llvm, clang and lldb libraries as shared (private)
  libraries.
* Adding other components from the LLVM project, such as lld.

cd4dcac89a Improve compatibility of calls to dirname() on constant strings.
As the xinstall(8) utility had to be patched up to work with the POSIXly
correct basename()/dirname() prototypes, we make it pretty hard to build
previous versions of FreeBSD on HEAD. xinstall(8) is part of the
bootstrap tools.

Add some logic to <libgen.h> to automatically detect bad calls to
dirname() based on the type of the argument. If the argument is of type
'const char *', we simply fall back to calling into dirname@FBSD_1.0
directly.

I'll also give basename() similar treatment when importing the
thread-safe version of that function.

This should hopefully make programs easier to maintain, and reduce code
duplication.

Work will begin on making ifconfig(8) use this library in the near future.

This code is still evolving. The interface should not be considered stable until
it is announced as such.

6ca8079c85 Pull in r265122 from upstream llvm trunk (by James Molloy):
Fix for pr24346: arm asm label calculation error in sub

  Some ARM instructions encode 32-bit immediates as a 8-bit integer
  (0-255) and a 4-bit rotation (0-30, even) in its least significant 12
  bits. The original fixup, FK_Data_4, patches the instruction by the
  value bit-to-bit, regardless of the encoding. For example, assuming
  the label L1 and L2 are 0x0 and 0x104 respectively, the following
  instruction:

    add r0, r0, #(L2 - L1) ; expects 0x104, i.e., 260

  would be assembled to the following, which adds 1 to r0, instead of
  260:

    e2800104 add r0, r0, #4, 2 ; equivalently 1

  The new fixup kind fixup_arm_mod_imm takes care of the encoding:

    e2800f41 add r0, r0, #260

  Patch by Ting-Yuan Huang!

This fixes label calculation for ARM assembly, and is needed to enable
ARM assembly sources for OpenSSL.

1680854946 Implement userspace gettimeofday(2) with HPET timecounter.
Right now, userspace (fast) gettimeofday(2) on x86 only works for
RDTSC.  For older machines, like Core2, where RDTSC is not C2/C3
invariant, and which fall to HPET hardware, this means that the call
has both the penalty of the syscall and of the uncached hw behind the
QPI or PCIe connection to the sought bridge.  Nothing can me done
against the access latency, but the syscall overhead can be removed.
System already provides mappable /dev/hpetX devices, which gives
straight access to the HPET registers page.

Add yet another algorithm to the x86 'vdso' timehands. Libc is updated
to handle both RDTSC and HPET.  For HPET, the index of the hpet device
to mmap is passed from kernel to userspace, index might be changed and
libc invalidates its mapping as needed.

Remove cpu_fill_vdso_timehands() KPI, instead require that
timecounters which can be used from userspace, to provide
tc_fill_vdso_timehands{,32}() methods.  Merge i386 and amd64
libc/<arch>/sys/__vdso_gettc.c into one source file in the new
libc/x86/sys location.  __vdso_gettc() internal interface is changed
to move timecounter algorithm detection into the MD code.

Measurements show that RDTSC even with the syscall overhead is faster
than userspace HPET access.  But still, userspace HPET is three-four
times faster than syscall HPET on several Core2 and SandyBridge
machines.

in such a way that it's thread-safe, but also guaranteed to succeed. C
libraries like glibc, musl and the one that's part of Solaris already
follow such an approach.

Move the existing implementation to another source file,
freebsd11_dirname.c to keep existing users of the API that pass in a
constant string happy, using symbol versioning.

Put a new version of the function in dirname.c, obtained from CloudABI's
C library. This version scans through the pathname string from left to
right, normalizing it, while discarding the last pathname component.

5f521d7ba7 Make libcrypt thread-safe. Add crypt_r(3).
glibc has a pretty nice function called crypt_r(3), which is nothing
more than crypt(3), but thread-safe. It accomplishes this by introducing
a 'struct crypt_data' structure that contains a buffer that is large
enough to hold the resulting string.

Let's go ahead and also add this function. It would be a shame if a
useful function like this wouldn't be usable in multithreaded apps.
Refactor crypt.c and all of the backends to no longer declare static
arrays, but write their output in a provided buffer.

There is no need to do any buffer length computation here, as we'll just
need to ensure that 'struct crypt_data' is large enough, which it is.
_PASSWORD_LEN is defined to 128 bytes, but in this case I'm picking 256,
as this is going to be part of the actual ABI.

b812fe4d6b [mips] add support for using the MIPS user register for TLS data.
This work, originally from Stacey Son, uses the MIPS UserReg for
reading the TLS data, and will fall back to the normal syscall path
when it isn't supported.

This code dynamically patches cpu_switch() to bypass the UserReg
instruction so to avoid generating a machine exception.

Thanks to sson for the original work, and to Dan Nelson for
bringing it to date and testing it on MIPS32 with me.

Tested:

* mips64 (sson)
* mips74k (dnelson_1901@yahoo.com) - AR9344 SoC, UserReg support
* mips24k (adrian) - AR9331 SoC, no UserReg support

b585cd3e2c Add __cxa_thread_atexit(3) API implementation.
This is the backing feature to implement C++11 thread storage duration
specified by the thread_local keyword.  A destructor for given
thread-local object is registered to be executed at the thread
termination time using __cxa_thread_atexit().  Libc calls the
__cxa_thread_calls_dtors() during exit(3), before finalizers and
atexit functions, and libthr calls the function at the thread
termination time, after the stack unwinding and thread-specific key
destruction.

There are several uncertainties in the API which lacks a formal
specification.  Among them:
- is it allowed to register destructors during destructing;
	we allow, but limiting the nesting level.  If too many iterations
	detected, a diagnostic is issued to stderr and thread forcibly
	terminates for now.
- how to handle destructors which belong to an unloading dso;
	for now, we ignore destructor calls for such entries, and
	issue a diagnostic.  Linux does prevent dso unload until all
	threads with destructors from the dso terminated.
It is supposed that the diagnostics allow to detect real-world
applications relying on the above details and possibly adjust
our implementation.  Right now the choices were to provide the slim
API (but that rarely stands the practice test).

Tests are added to check generic functionality and to specify some of
the above implementation choices.

9c24291370 Fix up setgrent(3) to have a POSIX-compliant prototype.
Just like with freelocale(3), I haven't been able to find any piece of
code that actually makes use of this function's return value, both in
base and in ports. The reason for this is that FreeBSD seems to be the
only operating system to have such a prototype. This is why I'm deciding
to not use symbol versioning for this.

It does seem that the pw(8) utility depends on the function's typing and
already had a switch in place to toggle between the FreeBSD and POSIX
variant of this function. Clean this up by always expecting the POSIX
variant.

There is also a single port that has a couple of local declarations of
setgrent(3) that need to be patched up. This is in the process of being

938809f941 Fix up prototypes of basename(3) and dirname(3) to comply to POSIX.
POSIX allows these functions to be implemented in a way that the
resulting string is stored in the input buffer. Though some may find
this annoying, this has the advantage that it makes it possible to
implement this function in a thread-safe way. It also means that they
can be implemented in a way that they work for paths of arbitrary
length, as the output string of these functions is never longer than
max(1, len(input)).

Portable code already needs to be written with this in mind, so in my
opinion it makes very little sense to allow the existing behaviour.
Prevent the base system from falling back to this by switching over to
POSIX prototypes.

I'm not going to bump the __FreeBSD_version for this. The reason is that
it's possible to account for this change in a portable way, without
depending on a specific version of FreeBSD. An exp-run was done some
time ago. As far as I know, all regressions as a result of this have
already been fixed.

I'll give this change some time to settle. In the long run I want to
replace our copies by ones that are thread-safe and don't depend on

use registers for passing function arguments that are at least as big as
long (e.g., amd64), or int and long are of the same size (e.g., i386).

globexp1() recursive calls, but glob0() was not supposed to be called
repeatedly in the original code. It finalize results by possible adding
original pattern for no match case, may return GLOB_NOMATCH error and
by sorting all things. Original pattern adding or GLOB_NOMATCH error
can happens each time glob0() called repeatedly, and sorting happens
for one item only, all things are never sorted. Second, f.e. "a{a"
pattern does not match "a{a" file but match "a" file instead
(just one example, there are many). Third, some errors (f.e. for limits
or overflow) can be ignored by GLOB_BRACE code because it forces return (0).

recursively called globexp1() to finalize things like glob0() does.
Reorganize braces code to work correctly.

fc4f075a1a Add PTRACE_VFORK to trace vfork events.
First, PL_FLAG_FORKED events now also set a PL_FLAG_VFORKED flag when
the new child was created via vfork() rather than fork().  Second, a
new PL_FLAG_VFORK_DONE event can now be enabled via the PTRACE_VFORK
event mask.  This new stop is reported after the vfork parent resumes
due to the child calling exit or exec.  Debuggers can use this stop to
reinsert breakpoints in the vfork parent process before it resumes.

ffdeef3234 libkvm: Improve physical address lookup scaling.
Instead of using a hash table to convert physical page addresses to offsets
in the sparse page array, cache the number of bits set for each 4MB chunk of
physical pages.  Upon lookup, find the nearest cached population count, then
add/subtract the number of bits from that point to the page's PTE bit.
Then multiply by page size and add to the sparse page map's base offset.

This replaces O(n) worst-case lookup with O(1) (plus a small number of bits
to scan in the bitmap).  Also, for a 128GB system, a typical kernel core of
about 8GB will now only require ~4.5MB of RAM for this approach instead of
~48MB as with the hash table.

More concretely, /usr/sbin/crashinfo against the same core improves from a
max RSS of 188MB and wall time of 43.72s (33.25 user 2.94 sys) to 135MB and
9.43s (2.58 user 1.47 sys).  Running "thread apply all bt" in kgdb has a
similar RSS improvement, and wall time drops from 4.44s to 1.93s.

aa3d69a636 1) This file full of direct char <-> wchar_t assignment, not converted, cut
them down. This hack still remains:
 * 2. Illegal byte sequences in filenames are handled by treating them as
 *    single-byte characters with a values of such bytes of the sequence
 *    cast to wchar_t.

2) Reword the comment in the hack above to reflect implementation.

3) Protect signed wchar_t from sign extension when a signed char is assigned
to it in the hack above.

3) Corresponding backward hack in g_Ctoc() was not implemented, so all
pathes with illegal byte sequences are skipped as result, implement it now.

4) globtilde() forget to convert expanded user home dir from multibyte to
wchar.

5) Protect globtilde() from long expansion truncation.

6) Results was not sorted according to collate as POSIX requires.

73a33477ca Add a regression test to make sure the Russian collation is actually working
when importing collation support from Dragonfly/Illumos amdmi3@ tested the
collation branch and reported an issue with Russian collation. John Marino fixed
the issue in Dragonfly and I merged it back to FreeBSD.

Now that Illumos is working on merging our fixes they (Lauri Tirkkonen) found
issues with the commit that fixes the russian collation in UTF-8 that resulted
in a crash with strxfrm(3) and the ISO-8859-5 locale (fixed in FreeBSD r302916).
This small test was written to ensure we do not bring back the old issue with
russian collation while fixing the other issue.

8d570f64aa Add a mask of optional ptrace() events.
ptrace() now stores a mask of optional events in p_ptevents.  Currently
this mask is a single integer, but it can be expanded into an array of
integers in the future.

Two new ptrace requests can be used to manipulate the event mask:
PT_GET_EVENT_MASK fetches the current event mask and PT_SET_EVENT_MASK
sets the current event mask.

The current set of events include:
- PTRACE_EXEC: trace calls to execve().
- PTRACE_SCE: trace system call entries.
- PTRACE_SCX: trace syscam call exits.
- PTRACE_FORK: trace forks and auto-attach to new child processes.
- PTRACE_LWP: trace LWP events.

The S_PT_SCX and S_PT_SCE events in the procfs p_stops flags have
been replaced by PTRACE_SCE and PTRACE_SCX.  PTRACE_FORK replaces
P_FOLLOW_FORK and PTRACE_LWP replaces P2_LWP_EVENTS.

The PT_FOLLOW_FORK and PT_LWP_EVENTS ptrace requests remain for
compatibility but now simply toggle corresponding flags in the
event mask.

While here, document that PT_SYSCALL, PT_TO_SCE, and PT_TO_SCX both
modify the event mask and continue the traced process.

5a5807dd4c Remove broken support for collation in [a-z] type ranges.
Only first 256 wide chars are considered currently, all other are just
dropped from the range. Proper implementation require reverse tables
database lookup, since objects are really big as max UTF-8 (1114112
code points), so just the same scanning as it was for 256 chars will
slow things down.

POSIX does not require collation for [a-z] type ranges and does not
prohibit it for non-POSIX locales. POSIX require collation for ranges
only for POSIX (or C) locale which is equal to ASCII and binary for
other chars, so we already have it.

No other *BSD implements collation for [a-z] type ranges.

Restore ABI compatibility with unused now __collate_range_cmp() which
is visible from outside (will be removed later).

(instead of continuing to wait) and for a long time SA_RESTART has
affected advisory file locks. These are both not compliant to POSIX.1.

To clarify that restarting means something, add a paragraph about fair
queuing. Note that the network lock manager does not implement fair
queuing.
