With the mac_priority(4) realtime policy active, users and processes in
the realtime group may promote existing threads and processes to

PRIV_SCHED_SETPOLICY which allows explicit creation of new realtime

One use case of this is when the pthread scheduling policy is set to

MFC after: 1 week
When bootstrapping on FreeBSD we use -DNO_SHARED so this case is already
handled correctly, but on non-FreeBSD we set NO_SHARED to no in
Makefile.boot.pre as not all OSes have static libraries available. As a
result, users of libdwarf fail to link during the cross tools stage due
to the newly-introduced dependency of libdwarf on libz.
This should perhaps be reworked to instead leave NO_SHARED as yes but
have an override (either implicit in bsd.prog.mk, or explicit via a new
variable) to turn off just the use of -static.

We don't currently honour _DP_foo when bootstrapping on non-FreeBSD, and

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 adds a new ng_device command, NGM_DEVICE_ETHERALIGN, which has no

packets sent out its hook to have ETHER_ALIGN bytes of padding at the
beginning of the packet. The ETHER_ALIGN padding is added only when
running on an architecture that requires strict alignment of IP headers
(based on the __NO_STRICT_ALIGNMENT macro, which is only #define'd on
x86 as of this writing).
This also adds ascii <-> binary command translation to ng_device, both for
the existing NGM_DEVICE_GET_DEVNAME and the new ETHERALIGN command.
This also gives a name to every ng_device node when it is constructed, using
the cdev device name (ngd0, ngd1, etc). This makes it easier to address

NOTE: HEADS UP read the note below if your kernel config is not including GENERIC!!
This patch does a bit of cleanup on TCP congestion control modules. There were some rather
interesting surprises that one could get i.e. where you use a socket option to change
from one CC (say cc_cubic) to another CC (say cc_vegas) and you could in theory get
a memory failure and end up on cc_newreno. This is not what one would expect. The
new code fixes this by requiring a cc_data_sz() function so we can malloc with M_WAITOK
and pass in to the init function preallocated memory. The CC init is expected in this
case *not* to fail but if it does and a module does break the
"no fail with memory given" contract we do fall back to the CC that was in place at the time.
This also fixes up a set of common newreno utilities that can be shared amongst other
CC modules instead of the other CC modules reaching into newreno and executing
what they think is a "common and understood" function. Lets put these functions in
cc.c and that way we have a common place that is easily findable by future developers or
bug fixers. This also allows newreno to evolve and grow support for its features i.e. ABE
and HYSTART++ without having to dance through hoops for other CC modules, instead
both newreno and the other modules just call into the common functions if they desire
that behavior or roll there own if that makes more sense.
Note: This commit changes the kernel configuration!! If you are not using GENERIC in
some form you must add a CC module option (one of CC_NEWRENO, CC_VEGAS, CC_CUBIC,
CC_CDG, CC_CHD, CC_DCTCP, CC_HTCP, CC_HD). You can have more than one defined
as well if you desire. Note that if you create a kernel configuration that does not
define a congestion control module and includes INET or INET6 the kernel compile will
break. Also you need to define a default, generic adds 'options CC_DEFAULT=\"newreno\"
but you can specify any string that represents the name of the CC module (same names
that show up in the CC module list under net.inet.tcp.cc). If you fail to add the
options CC_DEFAULT in your kernel configuration the kernel build will also break.

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.

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.

These allow one to non-destructively iterate over the set or clear bits
in a bitset. The motivation is that we have several code fragments
which iterate over a CPU set like this:
while ((cpu = CPU_FFS(&cpus)) != 0) {
cpu--;
CPU_CLR(cpu, &cpus);
<do something>;
}
This is slow since CPU_FFS begins the search at the beginning of the
bitset each time. On amd64 and arm64, CPU sets have size 256, so there
are four limbs in the bitset and we do a lot of unnecessary scanning.
A second problem is that this is destructive, so code which needs to
preserve the original set has to make a copy. In particular, we have
quite a few functions which take a cpuset_t parameter by value, meaning
that each call has to copy the 32 byte cpuset_t.
The new macros address both problems.

If MK_DEBUG_FILES=no then the Clang link rule has clang as .TARGET,
rather than clang.full, causing the implicit ${CFLAGS.${.TARGET:T}} to
be CFLAGS.clang, and thus pull in flags intended for when your compiler
is Clang, not when linking Clang itself. This doesn't matter if your
compiler is in fact Clang, but it breaks using GCC as, for example,
bsd.sys.mk adds -Qunused-arguments to CFLAGS.clang. This is seen when
trying to build a bootstrap toolchain on Linux where GCC is the system
compiler.
Thus, introduce a new internal NO_TARGET_FLAGS variable that is set by
Clang to disable the addition of these implicit flags. This is a bigger
hammer than necessary, as flags for .o files would be safe, but that is
not needed for Clang.
Note that the same problem does not arise for LDFLAGS when building LLD
with BFD, since our build produces a program called ld.lld, not plain
lld (unlike upstream, where ld.lld is a symlink to lld so they can

Older versions of LLD fail with big-endian compressed debug sections.
This was fixed in LLD upstream (commit c6ebc651b6fa) and merged to
FreeBSD main (commit d69d07569e) by dim.
External toolchains (e.g. the llvm12 package) will not yet have the fix.
These may be used to link against base system .a archives, so compressed
debug sections would cause trouble even though the base system is fixed.
Enable compressed debug sections again, for little-endian targets only.
As discussed on freebsd-hackers[1] I expect to undo this in the future
(using compressed debug everywhere), once fixed versions of lld are
widely available.
Note that to be pedantically correct we should check both the compiler
and the linker for compressed debug support, but given the external
