75b7de1b56 cache: fix up a corner case in r307650
If no negative entry is found on the last list, the ncp pointer will be
left uninitialized and a non-null value will make the function assume an
entry was found.

Fix the problem by initializing to NULL on entry.

8dfb293335 For CCBs allocated on the stack, we need to clear the entire CCB, not just
the header.  Otherwise stack garbage can lead to random flags getting set.

This showed up as 'camcontrol rescan all' failing with EINVAL because the
address type wasn't CAM_DATA_VADDR.

sbin/camcontrol/camcontrol.c:
	In rescan_or_reset_bus(), bzero the stack-allocated CCBs before
	use instead of clearing the body.

bc1b92e799 Add make rules to build LLVM IR from C/C++ sources.
As a foundation for future work with LLVM's Intermediate Representation (IR),
add new suffix rules that can be used to build .llo (text) or .bco (bitcode)
files from C or C++ sources.  This compilation step uses the same CFLAGS, etc.,
as are used for building .o files, with the exception of optimization flags.
Many of the things we would like to do with IR (e.g., instrumentation) work
better with unoptimized code, so our approach is to build .c->.bco without
optimization and then apply the optimization in post-analysis,
post-instrumentation linking.

The overall result of these changes is:

* one can "make foo.llo" or "make foo.bco" wherever "make foo.o" was supported
* new make variables IR_CFLAGS and IR_CXXFLAGS are available to inspect the
  flags that are used by Clang to generate the IR

These new rules are added unconditionally to our non-POSIX suffix rule set,
since we cannot inspect COMPILER_TYPE in sys.mk.  Future changes that depend
on these rules (e.g., building IR versions of binaries from bsd.prog.mk)
should use COMPILER_TYPE to determine when we can expect IR rules to succeed.

If WITHOUT_GNU_GREP is set then BSD grep will be installed as

knob.

7fbfba6490 Clear mbuf hashtype on loopback when RSS is enabled.
The hashtype on an outgoing mbuf reflects the correct hash on the
transmit side of the connection.  If this hash persists on loopback,
the receiving RSS/PCBGROUP code will use it to look up the pcbgroup
for the transmit side, which will often not match the pcbgroup for the
receive side of the connection.  This leads to TCP connections
hanging, and dropping the SYN/ACK packet.   This is essentially
the same as having a hardware network card generate mbufs with an
incorrect RSS hash.

There are a number of places which can set the hash on transmit,
so the simplest fix is to simply clear the hash at loopback time.
Clearing the hash allows a new, correct hash to be calculated in
software on the receive side.

a2159d1038 Document the unique requirements for upgrading more
prominently. Unlike in the past (dating back to the 4.x branch point),
you cannot upgrade from any point on the past couple of stable
branches to -current. Due to a bug in clang that existed before
r286035 in stable/9 or r286033 in stable/10, we cannot compile llvm
that's in 11.x or -current. Unfortunately, these revisions are after
9.3R and 10.3R on their respective branches. stable/11 and 11.0R are
not affected.

This also affects the upgrade path to 11 (including 11.0R) from
stable/9 and stable/10 (which would otherwise work, were it not for
this bug).

We also need to amend the 11.0R release notes.

23dcf48f60 Add FFS pager, which uses buffer cache read operation to validate pages.
See the comments for more detailed description of the algorithm.

The pager is used unconditionally when the block size of the
underlying device is larger than the machine page size, since local
vnode pager cannot handle the configuration [1].  Otherwise, the
vfs.ffs.use_buf_pager sysctl allows to switch to the local pager.

Measurements demonstrated no regression in the ever-important
buildworld benchmark, and small (~5%) throughput improvements in the
special microbenchmark configuration for dbench over swap-backed
md(4).

Code can be generalized and reused for other filesystems which use
buffer cache.

8c4ba2c67a [net80211] Initial full-offload scan support.
This is a very simple addition to the net80211 scan support.

It doesn't implement a replacement scan interface - it just disables
the pieces that we should disable to make this lifecycle a bit
more managable.

There's more work to come before full scan offload support is available
but it should be good enough for driver work.

* add a flag to say "full offload"
* don't do probe requests when scanning full-offload - firmware can do that
* don't do powersave transitions and buffering - firmware can do that

tested:

* iwm(4) - STA mode
* ath10k port (local, not in freebsd-head yet)
