Debugging boot issues can be helped by
logging each rc.d script as it is run
and being able to selectively enable/disable set -x
debug.sh provides an elaborate framework for debugging shell scripts.
For secure systems, we want to be paranoid about what we read
during boot.
dot() simply reads (.) arg file if it exists
vdot() if mac_veriexec is active, ignore unverified files
otherwise behaves much the same as dot()
safe_dot() in safe_eval.sh allows reading an untrusted file;
limiting the input to simple variable assignments.
In load_rc_config allow caller to provide an option to indicate how to
handle its arg:
-v use vdot()
-s use sdot() which will try to use vdot() and fallback to safe_dot()
The default is to read using dot()
rc_run_scripts()
encapsulate the running of rc.d scripts
so that we can easily call it more than twice.
We vdot local.rc.subr to pick up extensions (like
run_rc_scripts_final) and overrides.
We also allow rc.subr.local or rc.conf to set rc_config_xtra
eg (rc_config_xtra=XXX for historic compatibility)
rc use set -o verify around the reading in of rc.subr
This has no effect if mac_veriexec is not active, but if it is; ensures
rc.subr has not been tampered with.

This socket option was added in 6a2989fd54 together with LOCAL_CREDS.
Both options originate from NetBSD. The LOCAL_CREDS seems to be used by
some software and is covered by our test suite.
The main problem with LOCAL_CONNWAIT is that it doesn't work as
documented. A basic test shows that connect(2) indeed blocks, but
accept(2) on the other side does not wake it up. Indeed, I don't see what
code in the accept(2) path would go into the peer socket of a unix/stream
listener's child and would make wakeup(&so->so_timeo). I tried the test
even on a FreeBSD 6.4-RELEASE and it produced the same results as on
CURRENT.
The other thing that puzzles me is why that option would be useful even if
it worked? Because on unix/stream you can send(2) immediately after
connect(2) and that would put data on the peer receive buffer even before
listener had done accept(2). In other words, one side can do connect(2)
then send(2), only after the remote side would make accept(2) and the
remote would see the data sent before the accept(2). Again this
undocumented feature of unix(4) is present on all versions from FreeBSD 6
to CURRENT.

This function was used only in TCP before 446ccdd08e. It was born in
pain in 2016 to plug different complex panics in TCP timers. It wasn't
warmly accepted in phabricator by all of the reviewers and my recollection
of overall agreement was that "if you need this KPI, then you'd better fix
your code to not need it". However, the function served its duty well all
the way to FreeBSD 14. But now that TCP doesn't need it anymore, let's
retire it to reduce complexity of callout code and also to avoid its
further use.

Allocation code has been transferred from device_set_desc_internal() to

device_set_desc_internal(). The "copy" argument in
device_set_desc_internal() has been replaced with a flag which is set

ADAT connections transport 8, 4 or 2 audio channels depending on the
sample rate. Instead of splitting each physical ADAT port into 4
(potentially unmapped) stereo pcm devices, create just one pcm
device of variable channel width for every ADAT port.
Depending on the sample rate and channel width selected, the pcm
channels may be only partially mapped to ADAT channels and vice versa.
Added flexibility of the new channel mapping is also prerequisite to
introduce more pcm device layouts in follow-up commits.

Loading ispfw(4) moved from isp_pci_attach() to isp_reset().
Drop the reference to ispfw(4) after using it so one can kldunload(8) it.

A bunch of new helper functions to identify and validate active flash
regions for firmware, auxiliary and NVRAM.
Overhaul ISP_FW_* macros and make use of it when comparing firmware
versions. We can handle firmware versions up to 255.255.255.
Firmware load priority slightly changed:
For 27xx and newer adapters:
- load ispfw(4) firmware
- request (active) flash firmware information
- compare version numbers of ispfw(4) and flash firmware
- load firmware with highest version into RISC's RAM
- if loading ispfw(4) is disabled or failed - load firmware from flash
- if everything else fails use MBOX_LOAD_FLASH_FIRMWARE as fallback
For 26xx and older adapters nothing changed:
- load ispfw(4) firmware and load it into RISC's RAM
- if loading ispfw(4) is disabled or failed use MBOX_EXEC_FIRMWARE
- for 26xx a preceding MBOX_LOAD_FLASH_FIRMWARE is used
New read only sysctl(8)'s:
dev.isp.N.fw_version_run: the firmware version actually running
dev.isp.N.fw_version_ispfw: the firmware version provided by ispfw(4)
dev.isp.N.fw_version_flash: the (active) firmware version in flash
While here:
- firmware attribute handling/parsing reworked
+ renamed defines from ISP2400_FW_ATTR_* to ISP_FW_ATTR_*
+ changed values to match new handling/parsing
+ added some more attributes
- enable FLT support on 26xx based adapters
- log level adjustments
- new function return status codes (some for now, some for later use)
- some minor style changes
