From https://github.com/Yubico/libfido2:
libfido2 provides library functionality and command-line tools to
communicate with a FIDO device over USB, and to verify attestation
and assertion signatures.
libfido2 supports the FIDO U2F (CTAP 1) and FIDO 2.0 (CTAP 2)
protocols.
libfido2 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.
This is currently disabled for the 32-bit library build as libfido2 is

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.

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

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
toolchain constraint the extra complexity does not seem worthwhile.

In other words: if there's a typo in the main pf_rules we would allow

If $pf_program (i.e. pfctl) fails to set $pf_fules and
$pf_fallback_rules_enable is YES we will load $pf_fallback_rules_file if
set, or $pf_fallback_rules.
$pf_fallback_rules can include multiple rules, for example to permit

Make it work, but change the interface to be safe for non-root users. In
particular, right now interface only works for the tables which can be
minimally parsed by kernel to determine the table size. Then, userspace can
query the table size, after that it provides a buffer of needed size
and kernel copies out just table to userspace.
Main advantage is that user no longer need to be able to read /dev/mem,
the disadvantage is the need to have minimal parsers aware of the table
types. Right now the parsers are implemented for ESRT and PROP tables.
Future extension of the present interface might be a return of only
the table physical address, in case kernel does not have suitable
parser yet. Then, a privileged user could read the table from /dev/mem.
This extension, which logically equivalent to the old (non-worked)
EFIIOC_GET_TABLE variant, is not implemented until needed.

that the cgi interface runs on FreeBSD amd64.
* In FreeBSD amd64 some manual pages have broken X-refs. See hptrr(4)

* Also, we have broken links in our Release Notes. This is a

with a number of bug fixes; new features in use at Berkeley; performance

build system changes. Based on the TUHS archives, it contains none of
the V32 changes, however.
In addition to the source code analysis, Mike Karels relates the story
of how his group lost a customizes to V6 on a PDP-11/40 due to a disk
crash. Since V7 just came out and Bill Jolitz had just brought that up
elsewhere, they replaced their customized V6 with a V7 system, and that
base would eventually become 2.8BSD. (Quarter Century of Unix)

It supports basic VLAN offloads - tag extraction, injection and hardware
filtering. Inband MDIO connectivity is used for link status
monitoring through the miibus interface. Fixed-link mode is also
supported, which allows for operation of internal cpu to switch port.
Since no admin interrupts are present in hardware, link status polling
has to be used.
Due to a hardware bug software reset of the NIC results in a external
abort. Because of that most of the hardware initialization is done
during attach. This also means that in the case of an fatal error full
board reset is required.
