The introduction of <sched.h> improved compatibility with some 3rd
party software, but caused the configure scripts of some ports to
assume that they were run in a GLIBC compatible environment.
Parts of sched.h were made conditional on -D_WITH_CPU_SET_T being
added to ports, but there still were compatibility issues due to
invalid assumptions made in autoconfigure scripts.
The differences between the FreeBSD version of macros like CPU_AND,
CPU_OR, etc. and the GLIBC versions was in the number of arguments:
FreeBSD used a 2-address scheme (one source argument is also used as
the destination of the operation), while GLIBC uses a 3-adderess
scheme (2 source operands and a separately passed destination).
The GLIBC scheme provides a super-set of the functionality of the
FreeBSD macros, since it does not prevent passing the same variable
as source and destination arguments. In code that wanted to preserve
both source arguments, the FreeBSD macros required a temporary copy of
one of the source arguments.
This patch set allows to unconditionally provide functions and macros
expected by 3rd party software written for GLIBC based systems, but
breaks builds of externally maintained sources that use any of the
following macros: CPU_AND, CPU_ANDNOT, CPU_OR, CPU_XOR.
One contributed driver (contrib/ofed/libmlx5) has been patched to
support both the old and the new CPU_OR signatures. If this commit
is merged to -STABLE, the version test will have to be extended to
cover more ranges.
Ports that have added -D_WITH_CPU_SET_T to build on -CURRENT do
no longer require that option.
The FreeBSD version has been bumped to 1400046 to reflect this
incompatible change.

Text requests and responses can span multiple PDUs. In that case, the
sender sets the Continue bit in non-final PDUs and the Final bit in
the last PDU. The receiver responds to non-final PDUs with an empty
text PDU.
To support this, add a more abstract API in libiscsi which accepts and
receives key sets rather than PDUs. These routines internally send or
receive one or more PDUs. Use these new functions to replace the
handling of TextRequest and TextResponse PDUs in discovery sessions in
both ctld and iscsid.
Note that there is not currently a use case for large Text requests
and those are still always sent as a single PDU. However, discovery
sessions can return a text response listing targets that spans
multiple PDUs, so the new API supports sending and receiving multi-PDU
responses.

The states macro is the type for engine.c to use, with states1 being a
local macro for regexec to use to determine whether it can use the small
matcher or not (by comparing nstates and 8*sizeof(states1)). However,
macro bodies are expanded in the context of their use, and so when
regexec uses states1 it uses the current value of states, which is left
over as char * from the large version (or, really, the multi-byte one,
but that reuses large's states). For all supported architectures in
FreeBSD, the two have the same size, and so this confusion is harmless.
However, for architectures like CHERI where that is not the case (or
Windows's LLP64 as discovered by LLVM and fixed in 2010 in 2e071faed8e2)
and sizeof(char *) is bigger than sizeof(long) regexec will erroneously
try to use the small matcher when nstates is between sizeof(long) and
sizeof(char *) (i.e. between 64 and 128 on CHERI, or 32 and 64 on LLP64)
and end up overflowing the number of bits in the underlying long if it
ever uses those high states. On weirder architectures where sizeof(long)
is greater than sizeof(char *) this also fixes it to not fall back on
the large matcher prematurely, but such architectures are likely limited
to the embedded space, if they exist at all.
Fix this by swapping round states and states1, so that states1 is
defined directly as being long and states is an alias for it for the
small matcher case.

When keys are loaded from a received PDU, a copy of the received keys
block is saved in the keys struct and the name and value pointers
point into that saved block. Freeing the keys frees this block.
However, when keys are added to a keys struct to build a set of keys
later sent in a PDU, the keys data block pointer is not used and
individual key names and values hold allocated strings. When the keys
structure was freed, all of these individual key name and value
strings were leaked.
Instead, allocate copies of strings for names and values when parsing
a set of keys from a received PDU and free all of the individual key

hwpmc has been utterly broken for userspace binaries, and has been
labeling all samples from userspace binaries as dubious frames. The
issues are that:
-The check for ph.p_offset & (-ph.p_align) == 0 was mostly bogus. The
intent was to ignore all executable segments other than the first,
which when using BFD appeared in the first page, but with current LLD
a read-only data segment appears before the executable segment,
pushing the latter into the second page or later. This meant no
executable segment was ever found, and thus pi_vaddr remained
0. Instead of relying on BFD's layout, track whether we've seen an
executable segment explicitly with a local bool.
-Shared libraries were not parsing the segments to calculate pi_vaddr,
resulting in it always being 0. Again, when using BFD, the executable
segment started at the first page, and so pi_vaddr was genuinely
meant to be 0, but not with LLD's current layout. This meant that
pmcstat_image_link's offset calculation gave the base address of the
segment in memory, rather than the base address of the whole library
in memory, and so when adding that to pi_start/pi_end to get the
range of the executable sections in memory it double-counted the
offset of the first executable segment within the library. Thus we
need to do the exact same parsing for ET_DYN as we do for ET_EXEC,
which is simpler to write as special-casing ET_REL to not look for
segments. Note that, whilst PT_INTERP isn't needed for shared
libraries, it will be for PIEs, which pmcstat still fails to handle
due to not knowing the base address of the PIE; we get the base
address for libraries by MAP_IN events, and for rtld by virtue of the
process's entry address being rtld's, but have no equivalent for the
executable.

This works around brokenness in buildworld's bootstrapping logic: it
uses the source tree's metadata to collect dependency info (such as,
"libdwarf depends on libz") but links against static host libraries.
If these two are out of sync, as is the case if one builds a commit
prior to the introduction of the libz dependency, then the build fails
when trying to statically link nm(1).
Mitigate the problem by defining a weak uncompress() symbol which simply
returns an error. This ensures that the build won't fail when
statically linking libdwarf without zlib. The downside is that any
tools using libdwarf without zlib will now hit a runtime error if they
attempt to decode compressed sections, but at least they'll fail
deterministically, and compressed debug info is only enabled by default
in main.
In particular, this fixes building of branches lacking commit
dbf05458e3, such as releng branches, stable/12 and 13 and old

Add two underscore characters "__" to names of BIT_* and BITSET_*
macros to move them to the implementation name space and to prevent
a name space pollution due to BIT_* macros in 3rd party programs with
conflicting parameter signatures.
These prefixed macro names are used in kernel header files to define
macros in e.g. sched.h, sys/cpuset.h and sys/domainset.h.
If C programs are built with either -D_KERNEL (automatically passed
when building a kernel or kernel modules) or -D_WANT_FREENBSD_BITSET
(or this macros is defined in the source code before including the
bitset macros), then all macros are made visible with their previous
names, too. E.g., both __BIT_SET() and BIT_SET() are visible with
either of _KERNEL or _WANT_FREEBSD_BITSET defined.
The main reason for this change is that some 3rd party sources
including sched.h have been found to contain conflicting BIT_*
macros.
As a work-around, parts of shed.h have been made conditional and
depend on _WITH_CPU_SET_T being set when sched.h is included.
Ports that expect the full functionality provided by sched.h need
to be built with -D_WITH_CPU_SET_T. But this leads to conflicts if
BIT_* macros are defined in that program, too.
This patch set makes all of sched.h visible again without this
parameter being passed and without any name space pollution due
to BIT_* macros becoming visible when sched.h is included.
This patch set will be backported to the STABLE branches, but ports
will need to use -D_WITH_CPU_SET_T as long as there are supported
releases that do not contain these patches.

This reverts commit 2886c93d1b.
The original commit has two problems:
* It sets SO_SNDBUF to be as large as MAXLINE. But for unix domain
sockets, the send buffer is bypassed. Packets go directly to the
peer's receive buffer, so setting and querying SO_SNDBUF is
ineffective. To ensure that the socket can accept messages of a
certain size, it would be necessary to add a SO_PEERRCVBUF socket
option that could query the connected peer's receive buffer size.
* It sets MAXLINE to 8 kB, which is larger than the default sockbuf size
of 4 kB. That's ok for the builtin syslogd, which sets its recvbuf
to 80 kB, but not ok for alternative sysloggers, like rsyslogd, which
use the default size.
As a consequence, writing messages of more than 4 kB with syslog() as a
non-root user while running rsyslogd would cause the logging application
to spin indefinitely within syslog().

Some of the functions in msun can be implemented using a compiler
builtin function to generate a small number of instructions. Implement
this support in fma, fmax, fmin, and sqrt on arm64.
Care must be taken as the builtin can be implemented as a function
call on some architectures that lack direct support. In these cases
we need to use the original code path.
As we don't set errno on failure build with -fno-math-errno so the
toolchain doesn't convert a builtin into a function call when it
detects a failure, e.g. gcc will add a call to sqrt when the input
is negative leading to an infinite loop.

The change implements cexpl() for both ld80 and ld128 architectures.
Testing was done on x86_64 and aarch64 systems.
Along the way sincos[fl]() use an optimization that reduces the argument
to being done one rather than twice. This optimization actually pointed
to a bug in the ld128 version of sincosl(), which is now fixed. In
addition, the minmax polynomial coefficients for sincosl() have been

* Misuses of copysignl() in sinpil() and tanpil().
* Redo the splitting of argument 'x' into an integer part and
remainder. The remainder must satify 0 <= r < 1.
* Update the reduction of the integer part to something that can
easily be seen as even or odd, e.g., sin(pi*x) = (-1)^n*sin(pi*r)
with n <= 2^112 and we an reduce n by subtracting integer powers
of 2.
* In s_cospil.c, fix typos where 'x' is used where 'ax', the
remainder, is required.
* In tanpil(), fix the use of an uninitialized variable, ax = fabsl(ax),
ax should be x in fabsl().
One item of note, in the limited tested on aarch64, the max ULP
for sinpil() and cospil() were less than 1.1 ULP, which is higher
that the desired max ULP less than 1. This was traced to the
kernel for cosl() in the fundamental interval [0,pi/4].
The coefficients in the minmax polynomial likely need refinement.

The last two drivers that required sppp are cp(4) and ce(4).
These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.
Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially. Later they have dropped
support for Linux drivers to. As of mid-2020 they don't even
have a developer to maintain their Windows driver. However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.
These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP. Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.
Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part. Further maintenance of these
drivers in the tree shouldn't be a big deal.
While doing that, remove some cruft and enable cp(4) compilation
on amd64. The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.

In some configurations (e.g. powerpc64) the llvm-readobj tool also needs
contrib/llvm-project/llvm/BinaryFormat/MsgPackWriter.cpp, so add it to
libllvm.

Fixes: 1b85b68da0
From https://github.com/PJK/libcbor:
libcbor is a C library for parsing and generating CBOR, the general-
purpose schema-less binary data format.
libcbor will be used by ssh to support FIDO/U2F keys. It is currently
intended only for use by ssh, and so is installed as a PRIVATELIB and is
placed in the ssh pkgbase package.
cbor_export.h and configuration.h were generated by the upstream CMake
build. We could create them with bmake rules instead (as NetBSD has
done) but this is a fine start.
This is currently disabled for the 32-bit library build as libfido2 is
not compatible with the COMPAT_32BIT hack in usb_ioctl.h, and there is
no need for libcbor without libfido2.
