This update is primarily bug fixes in C++ symbol demangling, including:
- rvalue reference
- builtin type auto and decltype(auto)
- revamped support for function return types
- formatting fixes
- omit void when its the only param
- ref-qualifiers and others in function types
- type qualifiers in pointer-to-member function types
- incorrect handling regarding CV-qualifiers in function types
- ref-qualifier found in nested-name
- properly handle <name> ::= <substitute><template-args>
- make sure that nested function name is not a substitute candidate
- correctly handle expression in template args
- skip unknown substitution abbreviations

valid when adding a pool (ippool -A), not when removing a pool
(ippool -R). It is a command line syntax error if specifying a seed (-S)
is specified when emoving a pool (-R).
The declaration was already inactive when INET6 was enabled
and it causes a build error in the other case because of
a conflict with the correct definition in stdlib.h.

This change implements NOTE_ABSTIME flag for EVFILT_TIMER, which
specifies that the data field contains absolute time to fire the
event.
To make this useful, data member of the struct kevent must be extended
to 64bit. Using the opportunity, I also added ext members. This
changes struct kevent almost to Apple struct kevent64, except I did
not changed type of ident and udata, the later would cause serious API
incompatibilities.
The type of ident was kept uintptr_t since EVFILT_AIO returns a
pointer in this field, and e.g. CHERI is sensitive to the type
(discussed with brooks, jhb).
Unlike Apple kevent64, symbol versioning allows us to claim ABI
compatibility and still name the new syscall kevent(2). Compat shims
are provided for both host native and compat32.

The intention is that the branch goes to the instruction after the
branch, effectively turning it on a nop. The branch adds the runtime
PC, but we were adding it statically too.
I noticed the oddity by inspection, but llvm-objdump seems to agree,
since it now prints things like:

This change is a portion of LLD rev 305212 which accidentally ended
up in my svn tree. We do want to backport the change to LLD 4.0, but
it needs additional work and was not supposed to be included in
r319887.
If two sections contained relocations to absolute symbols with the same
value we would crash when trying to access their sections. Add a check that
both symbols point to sections before accessing their sections, and treat
absolute symbols as equal if their values are equal.

now. The option does not presently work. However, similar functions in
ipfstat (for state) and ipnat (for nat) do work and provide outputs that
can be easily parsed by shell scripts or subsequently loaded into CSV
files. The intention here is to return to this option to make it work.
I suspect the problem is in printpoolfields.c.
It implements missing man(7) macros used in base by kerberos/ntp and makes them
supported by mandoc.
This import should have been done before the removal of groff.

All manpages in base are now compatible with mandoc(1), all roff documentation
will be relocated in the doc tree. man(1) can now use groff from the ports tree
if it needs.
Also remove checknr(1) and colcrt(1) which are only useful with groff.

The problem is that when the parameter 'pat' is null, the function locally
allocates a NULL string but never frees it.
Instead of tracking the local alloc, it is noted that the while(*pat) never
enters when there is a local alloc.
So instead of doing the local alloc, check that 'pat' is null before the
while(*pat) loop.

In the absense of a more specific handler for TRAP_CAP (generated by
ENOTCAPABLE or ECAPMODE while in capability mode) treat it as a trace
trap.
Example usage (testing the bug in PR219173):
% proccontrol -m trapcap lldb usr.bin/hexdump/obj/hexdump -- -Cv -s 1 /bin/ls
...
(lldb) run
Process 12980 launching
Process 12980 launched: '.../usr.bin/hexdump/obj/hexdump' (x86_64)
Process 12980 stopped
* thread #1, stop reason = trace
frame #0: 0x0000004b80c65f1a libc.so.7`__sys_lseek + 10
...
In the future we should have LLDB control the trapcap procctl itself
(as it does with ASLR), as well as report a specific stop reason.
This change eliminates an assertion failure from LLDB for now.
The original blacklist library supported two notification types:
- failed auth attempt, which incremented the failed login count
by one for the remote address
- successful auth attempt, which reset the failed login count
to zero for that remote address
When the failed login count reached the limit in the configuration
file, the remote address would be blocked by a packet filter.
This patch implements a new notification type, "abusive behavior",
and accepts, but does not act on an additional type, "bad username".
It is envisioned that a system administrator will configure a small
list of "known bad usernames" that should be blocked immediately.

This is no-op and only for reference: the S/390 port seems to be elusive

It is likely newer attempts will focus on a newer toolchain using clang
