If we're sending a packet via pf_route()/pf_route6() we check for packet
size and potentially generate ICMP(6) packet too big messages. If we do,
don't consider this a rejected packet. That is, return PF_PASS and set
the mbuf to NULL rather than returning PF_DROP.
This matters for locally generated packets, because with PF_DROP we
can end up returning EACCES to userspace, causing the connection to
terminate. Instead, with PF_PASS and a NULL mbuf this is translated to
PFIL_CONSUMED, which does not return an error to userspace.

In commit cf1eaaf41c I added the WITH_LLVM_LINK_STATIC_LIBRARIES

However, the checks were incorrect: when WITH_LLVM_LINK_STATIC_LIBRARIES

In commit 2e47f35be5 libllvm, libclang and liblldb were converted into
private shared libraries. This allowed clang, lld, lldb, and other llvm
tools to be linked against these shared libraries, which makes them
smaller and avoids duplication.
However, this also comes at the cost of some performance, since the
dynamic libraries are quite large, and contain lots of long symbols
(mangled C++ identifiers).
Add a WITH_LLVM_LINK_STATIC_LIBRARIES build knob that can be used to go
back to the previous behavior: libllvm, libclang and liblldb are built
as internal static libraries, i.e. only available during buildworld, and
fully linked into the various executables such as clang, lld, etc.

An internet draft (expected to become an RFC someday)
https://datatracker.ietf.org/doc/draft-ietf-nfsv4-posix-acls
describes an extension to NFSv4.2 to handle POSIX draft ACLs.
This is the final patch in the series that enables
the extension of NFSv4.2 to support POSIX draft ACLs.
At this time, only UFS mounted with the "acls" option
will work, and only for FreeBSD built with these patches.
Patches for client and server for the Linux kernel are
in the works. (I'll admit my next little project is
cleaning the Linux patches up for submission for upstream.)
To make these changes really useful, the FreeBSD port
of OpenZFS needs to be patched to add POSIX draft ACL
support. (Support for POSIX draft ACLs is already in
the Linux port of OpenZFS.)
Interopeability with NFSv4.2 clients and servers that
do not support this extension should not be a problem.

An internet draft (expected to become an RFC someday)
https://datatracker.ietf.org/doc/draft-ietf-nfsv4-posix-acls
describes an extension to NFSv4.2 to handle POSIX draft ACLs.
This is the fifth of several patches that implement the
above draft.
This one mostly adds an extra argument to two functions
in nfscommon.ko. Unfortunately, these functions are
called in many places, so the changes are numerous, but
straightforward.
Since the internal KAPI between the NFS modules is changed
by this commit, all of nfscommon.ko, nfscl.ko and nfsd.ko
must be rebuilt from sources.
There should be no semantics change for the series at
this point.

private shared libraries. This allowed clang, lld, lldb, and other llvm
tools to be linked against these shared libraries, which makes them
smaller and avoids duplication.
However, upstream builds the shared libraries using several visibility
options, which reduces the number of external symbols, and makes the
libraries a bit smaller.
On my test machine:
* libprivatellvm.so goes from 75643 to 34706 symbols (~54% reduction)
* libprivateclang.so goes from 53250 to 33531 symbols (~37% reduction)
* libprivatelldb.so goes from 27242 to 18798 symbols (~31% reduction)
Note: to get the full benefit, a clean build is required. Incremental
builds should still work, but I didn't want to force a full rebuild on

and don't trigger ifnet_arrival_event and ifnet_departure_event for a
rename, as the interface isn't being detached from any protocol. The
consumers of the arrival/departure events are divided into a few
categories:
- which indeed need to do the same actions as if interface was fully
detached and attached: routing socket and netlink notifications to
userland and the Linux sysfs. All addressed by this commit.
- which build their logic based on an interface name, but should actually
update their database on rename: packet filters. This commit leaves
them with the old behavior - emulate full detach & attach, but this
should be improved.
- which shouldn't do anything on rename, not touched by the commit.
- ng_ether and if_tuntap, that are special and will be addressed by
separate commits.
We first want to give a chance to all owners of multicast addresses to

a possible use after free.
