With the upcoming multipath changes described in D24141,
rt->rt_nhop can potentially point to a nexthop group instead of
an individual nhop.
To simplify caller handling of such cases, change ifa_rtrequest() callback
to pass changed nhop directly.

This is a temporary hack to aid with config(8) changing in r360443.
It will not work for all cases.
env PATH is used because universe-toolchain is only built when worlds
are built, and then only if clang is needed, so it may not exist.
universe-toolchain needs to be expanded to always be built, inspected to
remove non-cross-build-safe tools, used for buildworld/buildkernel,
and potentially incremental build support.

This behavior is most relevant for ipfw(4) as documented in syslog.conf(5).
The recent addition of property-based regex filters in r359327 is a
fine workaround for this but the behavior was present since 1997 and
documented.
This only fixes local matching of the "kernel program". It does not
change the forwarded format at all. On the remote side it will still
be "kernel: ipfw:" and not be parsed as a kernel message. This matches
old behavior.

particular, the cv_wait() in sendfile() does not get interrupted until

This may happen, for instance, if one happens to have an alias of diff to
diff -up and attempts to specify the amount of context on top of that.
Aliases like this may cause other problems, but if they're really not ever
generating non-unified diffs then we should at least not break that
use-case.
In addition, we'll now pick up a format mismatch if -p is specified with
!contextual && !unified && !unset.
Fix up a small trailing whitespace nit in the tests while we're here, and
add tests to make sure that we can double up all the formatting options.

vm_page_release_locked() must not free the page. Once the xbusy lock is

While we're here, let's stylize these as functions instead of just raw text.
A future change may allow arbitrary data arguments to be passed some of
these, and the distinction is useful.
The NFS code had a bunch of Mac OS/X accessor functions named uio_XXX
left over from the port to Mac OS/X. Since that port is long forgotten,
replace the calls with the code generated by the FreeBSD macros for these
in nfskpiport.h. This allows the macros to be deleted from nfskpiport.h
and I think makes the code more readable.
This patch should not result in any semantic change.

In the process, change it slightly: readConfFiles will take a string like

We don't actually need to fetch loader_conf_files as much as we do; we've
already fetched it once at the beginning, we only really need to fetch it

While here, drop a note about the recursion so that I stop trying to

This largely reuses the TLS TOE support added in r330884. However,

Without this patch, sosend_generic() will try to use top->m_pkthdr.len,
assuming that the first mbuf has a pkthdr.
When a list of ext_pgs mbufs is passed in, the first mbuf is not a
pkthdr and cannot be post-r359919. As such, the value of top->m_pkthdr.len
is bogus (0 for my testing).
This patch fixes sosend_generic() to handle this case, calculating the
total length via m_length() for this case.
There is currently nothing that hands a list of ext_pgs mbufs to
sosend_generic(), but the nfs-over-tls kernel RPC code in
projects/nfs-over-tls will do that and was used to test this patch.

This was changed in the review process for the flags sysctl. The

gdb.
- Add a new TCP_RXTLS_ENABLE socket option to set the encryption and
authentication algorithms and keys as well as the initial sequence
number.
- When reading from a socket using KTLS receive, applications must use
recvmsg(). Each successful call to recvmsg() will return a single
TLS record. A new TCP control message, TLS_GET_RECORD, will contain
the TLS record header of the decrypted record. The regular message
buffer passed to recvmsg() will receive the decrypted payload. This
is similar to the interface used by Linux's KTLS RX except that
Linux does not return the full TLS header in the control message.
- Add plumbing to the TOE KTLS interface to request either transmit
or receive KTLS sessions.
- When a socket is using receive KTLS, redirect reads from
soreceive_stream() into soreceive_generic().
- Note that this interface is currently only defined for TLS 1.1 and
1.2, though I believe we will be able to reuse the same interface
and structures for 1.3.
bhyve uses cached copies of the MSI capability registers to generate
MSI interrupts for device models. Previously, these cached fields
were only set when the MSI capability control register was updated.
The Linux kernel recently adopted a change to deal with races in MSI
interrupt delivery that writes to the MSI capability address and data
registers to alter the destination of MSI interrupts without writing
to the MSI capability control register. bhyve was not updating its
cached registers for these writes and continued to send interrupts
with the old data value to the old address. Fix this by recomputing
the cached values for every write to any MSI capability register.
