In some cases it seems that the PHY mode can only be identified by
matching against the corresponding device node name in the FDT. r334880
broke this for the case where the node name contains a unit address.
Fix the problem by allowing a match in that case.

Synproxy was accidentally broken by r335569. The 'return (action)' must be
executed for every non-PF_PASS result, but the error packet (TCP RST or ICMP
error) should only be sent if the packet was dropped (i.e. PF_DROP) and the
return flag is set.

The issue found with gcc6 build (originally on illumos, confirmed on FreeBSD).
Mark it __unused.
Differential Revision: https://reviews.freebsd.org/D13109
When shutting down a vnet jail pf_shutdown() clears the remaining states, which
through pf_clear_states() calls pf_unlink_state().
For synproxy states pf_unlink_state() will send a TCP RST, which eventually
tries to schedule the pf swi in pf_send(). This means we can't remove the
software interrupt until after pf_shutdown().

o Fix the parsing of the device path. a last minute change terminated
it too soon.
o Kill setting LINES. We don't need to do it, and even if we did hard
coding it to 24 is wrong.
o Now that the console is working again for the loader, adjust the
printfs to be more in line with other platforms.
note that r336270's commit message was slightly incorrect. It changed
the default setting of the console to honor the ConOut
variable. Overrides via the command line are still possible, and we
use the devices in ConOut to set the proper console. If, for example,
serial cosnole is specified, we'll set console to "efi" if ConOut has
a serial port list and to either "efi comconsole" or "comconsole efi"
if not depending on whether -D or -D -h was specified.

For server machines, ComOut is set to the set of devices that the efi
console suppots. Parse it to see if we have serial, video or both.
Make that take precidence over the command line args. boot1.efi parses
them, but loader.efi doesn't. It's not clear where to read boot.conf
from, so we don't do that. The command line args can still be set via
efibootmgr, which is more inline with the UEFI boot manager to replace
that. These args are typically used only to set serial vs video and
the com speed line. We can infer that from ComOut, so do so.
Remember the com speed and hw.uart.console to match.

So long as the TCP connection to a pNFS DS isn't shared with other DSs,
it can be closed down when the DS is being disabled in the pNFS client.
This causes any RPCs in progress to fail.
This patch only affects the NFSv4.1 pNFS client when errors occur
while doing I/O on a DS.

This moves the bulk of the geli support from lib386/biosdisk.c into a new
geli/gelidev.c which implements a devsw-type device whose dv_strategy()
function handles geli decryption. Support for all arches comes from moving
the taste-and-attach code to the devopen() function in libsa.
After opening any DEVT_DISK device, devopen() calls the new function
geli_probe_and_attach(), which will "attach" the geli code to the open_file
struct by creating a geli_devdesc instance to replace the disk_devdesc
instance in the open_file. That routes all IO for the device through the
geli code.
A new public geli_add_key() function is added, to allow arch/vendor-specific
code to add keys obtained from custom hardware or other sources.
With these changes, geli support will be compiled into all variations of
loader(8) on all arches because the default is WITH_LOADER_GELI.

to it being a common name elsewhere. Rename the old kzip one
to subr_inflate.c.
This actually fixes the build issues on sparc64 that my inclusion of
.PATH ${SYSDIR}/kern created in r336244, so also revert the broken
workaround I committed in r336249.
This slipped passed me because apparently, I never did a clean build.
Doing so ensures that all threads sharing the pmap have a consistent
view of the mapping. This fixes the problem described in the commit
log message for r329254 without the overhead of an extra fault in the
common case. (Once the riscv pmap_enter() implementation is similarly
modified, the workaround added in r329254 can be removed, reducing the
overhead of CoW faults.)
See also r335784 for amd64. The mips implementation of pmap_enter()
already reused the PV entry from the old mapping.

Eliminate 4 of the copies of the arg parsing in /boot/laoder

Sponsored by: Netflix
Differential Revision: https://reviews.freebsd.org/D16205
boot_parse_arg to parse a single arg
boot_parse_cmdline to parse a command line string
boot_parse_args to parse all the args in a vector
boot_howto_to_env Convert howto bits to env vars
boot_env_to_howto Return howto mask mased on what's set in the environment.
All these routines return an int that's the bitmask of the args
translated to RB_* flags. As a special case, the 'S' flag sets the
comconsole_speed env var. Any arg that looks like a=b will set the env
key 'a' to value 'b'. If =b is omitted, 'a' is set to '1'. This
should help us reduce the number of redundant copies of these routines
in the tree. It should also give a more uniform experience between
platforms.
Also, invent a new flag RB_PROBE that's set when 'P' is parsed. On
x86 + BIOS, this means 'probe for the keyboard, and if it's not there
set both RB_MULTIPLE and RB_SERIAL (which means show the output on
both video and serial consoles, but make serial primary). Others it
may be some similar concept of probing, but it's loader dependent
what, exactly, it means.
These routines are suitable for /boot/loader and/or the kernel,
though they may not be suitable for the tightly hand-rolled-for-space
environments like boot2.

an I/O attempt on a DS to the server via LayoutReturn.
The current FreeBSD client can generate these errors for an operational
DS while doing a recovery of a mirror after a mirrored DS has been repaired.
I am not sure why these errors occur, but my best current guess is a race
between the Layout Recall issued by the kernel code run from pnfsdscopymr(8)
and a Read operation on the DS for the file bing copied.
The errrors are not fatal, since the client falls back on doing I/O through
the MDS, which can do the I/O successfully as a proxy. (The fact that the
MDS can do this indicates that the file does still exist on the functioning
DS.)
This patch only affects behaviour of the pNFS client and only when using
Flexible File layouts.

Without this patch, the NFSv4.1 pNFS client shared a single TCP connection
for all DSs that resided on the same machine. This made disabling one of
the DSs impossible. Although unlikely, it is possible that the storage
subsystem has failed in such a way that the storage for one DS on a machine
is no longer functioning correctly, but the storage used by another DS on
the same machine is still ok. For this case, it would be nice if a system
can fail one of the DSs without failing them all.
This patch changes the default behaviour to use separate TCP connections
for each DS even if they reside on the same machine.
I do not believe that this will be a problem for extant pNFS servers, but
a sysctl can be set to restore the old behaviour if this change causes a
problem for an extant pNFS server.
This patch only affects the NFSv4.1 pNFS client.

Request init/fini array on FreeBSD 12 and later
Summary:
It seems a bad idea to change the default in the middle of a release
branch due to possible changes in global ctor / dtor ordering between
.ctors and .init_array. With FreeBSD 11.0's release imminent lets
change the default now for FreeBSD 12 (the current development
stream) and later.
FreeBSD rtld has supported .init_array / .fini_array for many years.
As of Jan 1 2017 all supported FreeBSD releases and branches will
have support.
