At present the linker type detection is used only for enabling build-id,

It adds support for mangling symbols exported by a module by prepending

It allows the use of a macro as the module name in the DECLARE_MACRO()

It allows the code to register stack aliases (e.g. both a generic name
["default"] and version-specific name ["default_10_3p1"]).
With these changes, it is trivial to compile TCP stack modules with
the name defined in the Makefile and to load multiple versions of the
same stack simultaneously. This functionality can be used to enable
side-by-side testing of an old and new version of the same TCP stack.
It also could support upgrading the TCP stack without a reboot.

Normally META_MODE ignores host files for "meta mode" decisions on whether a
file should be rebuilt or not. This is because a simple installworld can
update timestamps and cause the next build to rebuild all host tools, when the
previous ones may not have any changes in the source tree. These tools are
normally still ABI compatible. They are only rebuilt if NO_META_IGNORE_HOST is
set from the workaround/hack in r301467.
One of the major problems with this is when a host tool has objects spread
across many revisions that have mixed-ABI. For example, if struct stat were to
change on the host, some objects for a tool may have different ideas of that
struct's definition. If just 1 source file were modified and rebuilt and
linked into the tool, then that toll will have mixed-ABI objects and crash.
This exact thing happened with the ino64 commit in r301467 followed by a
trivial update to libbfd in r318750. The resulting binary would crash in
buildworld.
Sponsored by: Dell EMC Isilon
See r301467 for more details on NO_META_IGNORE_HOST. Usually the full
list of host ignores should have no real impact on the host tools. The
headers however may reliably define what the ABI is for the host. It
may be useful to allow using the headers for the build but still not
caring about things like /bin/sh, /lib/libedit.so, etc.

ABI breakage is mitigated by providing compatibility using versioned
symbols, ingenious use of the existing padding in structures, and
by employing other tricks. Unfortunately, not everything can be
fixed, especially outside the base system. For instance, third-party
APIs which pass struct stat around are broken in backward and
forward incompatible ways.
Kinfo sysctl MIBs ABI is changed in backward-compatible way, but
there is no general mechanism to handle other sysctl MIBS which
return structures where the layout has changed. It was considered
that the breakage is either in the management interfaces, where we
usually allow ABI slip, or is not important.
Struct xvnode changed layout, no compat shims are provided.
For struct xtty, dev_t tty device member was reduced to uint32_t.
It was decided that keeping ABI compat in this case is more useful

ENA is a networking interface designed to make good use of modern CPU
features and system architectures.
The ENA device exposes a lightweight management interface with a
minimal set of memory mapped registers and extendable command set
through an Admin Queue.
The driver supports a range of ENA devices, is link-speed independent
(i.e., the same driver is used for 10GbE, 25GbE, 40GbE, etc.), and has
a negotiated and extendable feature set.
Some ENA devices support SR-IOV. This driver is used for both the
SR-IOV Physical Function (PF) and Virtual Function (VF) devices.
ENA devices enable high speed and low overhead network traffic
processing by providing multiple Tx/Rx queue pairs (the maximum number
is advertised by the device via the Admin Queue), a dedicated MSI-X
interrupt vector per Tx/Rx queue pair, and CPU cacheline optimized
data placement.
The ENA driver supports industry standard TCP/IP offload features such
as checksum offload and TCP transmit segmentation offload (TSO).
Receive-side scaling (RSS) is supported for multi-core scaling.
The ENA driver and its corresponding devices implement health
monitoring mechanisms such as watchdog, enabling the device and driver
to recover in a manner transparent to the application, as well as
debug logs.
Some of the ENA devices support a working mode called Low-latency
Queue (LLQ), which saves several more microseconds. This feature will
be implemented for driver in future releases.

After FreeBSD SVN revision 236814, the pass(4) driver changed from
only doing error recovery when the CAM_PASS_ERR_RECOVER flag was
set on a CCB to sometimes doing error recovery if the passed in
retry count was non-zero.
Error recovery would happen if two conditions were met:
1. The error recovery action was simply a retry. (Which is most
cases.)
2. The retry_count is non-zero. (Which happened a lot because of
cut-and-pasted code.)
This explains a bug I noticed in with camcontrol:
# camcontrol tur da34 -v
Unit is ready
# camcontrol reset da34
Reset of 1:172:0 was successful
At this point, there should be a Unit Attention:
# camcontrol tur da34 -v
Unit is ready
No Unit Attention.
Try it again:
# camcontrol reset da34
Reset of 1:172:0 was successful
Now set the retry_count to 0 for the TUR:
# camcontrol tur da34 -v -C 0
Unit is not ready
(pass42:mps1:0:172:0): TEST UNIT READY. CDB: 00 00 00 00 00 00
(pass42:mps1:0:172:0): CAM status: SCSI Status Error
(pass42:mps1:0:172:0): SCSI status: Check Condition
(pass42:mps1:0:172:0): SCSI sense: UNIT ATTENTION asc:29,2 (SCSI bus reset occurred)
(pass42:mps1:0:172:0): Field Replaceable Unit: 2
There is the unit attention. camcontrol(8) has a default
retry_count of 1, in case someone sets the -E flag without
setting -C.
The CAM_PASS_ERR_RECOVER behavior was only broken with the
CAMIOCOMMAND ioctl, which is the synchronous pass(4) API. It has
worked as intended (error recovery is only done when the flag
is set) in the asynchronous API (CAMIOQUEUE ioctl).

In passsendccb(), when calling cam_periph_runccb(), only

Specifically, set '-mabi=XX' in AFLAGS, CFLAGS, and LDFLAGS. This permits
building MIPS worlds and binaries with a toolchain whose default output
does not match the desired TARGET_ARCH.
_LDFLAGS (which is used with LD instead of with CC) required an update as
LD does not accept the -mabi flags (so they must be stripped from LDFLAGS
when generating _LDFLAGS). For bare uses of LD (rather than linking via
CC), the desired ABI must be set by setting an explicit linker emulation
as done in r316514 for kernels and kernel modules.

This should no longer be necessary after r316620 as all places that

In a cross-build, the build-tools are native host binaries. We do not
want to rebuild them when building for the target. Bmake previously
did not support checking .NOMETA on an existing target, so .NOMETA_CMP
was used here. However, .NOMETA_CMP still triggers meta mode conditions
if the number of commands or the command changes. In r312467 the paths
to build ncurses files were modified and thus triggered meta mode to
rebuild the build tools (make_keys, make_hash) in ncurses during the
target build. Bmake 20160604 committed in r301462 changed .NOMETA to
also skip meta mode logic for an existing .meta file as well, thus it
is now the proper fix here.
I explored moving the build-tools output to WORLDTMP/tools with
relatively good success, but have concerns that doing so would be
problematic for downstream vendors who use LOCAL_TOOL_DIRS and
expect the tools to be in current OBJDIR for the target. It also
adds more complexity into finding the tools during target build
and handling of where they are for rescue/rescue and
mkcsmapper_static/mkesdb_static which should really not be connected in
build-tools anyway.

Multiple periodic scripts sleep for a random amount of time in order to
mitigate the thundering herd problem. This is bad, because the sum of
multiple uniformly distributed random variables approaches a normal
distribution, so the problem isn't mitigated as effectively as it would be
with a single sleep.
This change creates a single configurable anticongestion sleep. periodic
will only sleep if at least one script requires it, and it will never sleep
more than once per invocation. It also won't sleep if periodic was run
interactively, fixing an unrelated longstanding bug.

The goal of this work is to remove the explicit dependency for ctl(4)
on iscsi(4), so end-users without iscsi(4) support in the kernel can
use ctl(4) for its other functions.
This allows those without iscsi(4) support built into the kernel to use
ctl(4) as a test mechanism. As a sidenote, this was possible around the
10.0-RELEASE period, but made impossible for end-users without iscsi(4)
between 10.0-RELEASE and 11.0-RELEASE.
Automatically load cfiscsi(4) from ctladm(8) and ctld(8) for backwards
compatibility with previously releases. The automatic loading feature is
compiled into the beforementioned tools if MK_ISCSI == yes when building
world.
Add a manpage for cfiscsi(4) and refer to it in ctl(4).

man(1) has some logic to use two spaces after a full stop, which is
useful for spotting sentence breaks in monospace fonts. However,
this logic is very simple, treating almost all '.' characters as
end-of-sentence markers, unless followed by certain other
characters. For example, '.,' is not end-of-sentence, and neither
is ".) ", but ".)" at the end of a line triggers the sentence-end
detection.
Apply a zero-width space to a few instances of this in share/man,
and also supply a missing full stop for an instance that occurred at
the end of a sentence.
Leave untouched several instances that are at the end of a sentence
or list element.

Add a clock_nanosleep() syscall, as specified by POSIX.
Make nanosleep() a wrapper around it.
Attach the clock_nanosleep test from NetBSD. Adjust it for the
FreeBSD behavior of updating rmtp only when interrupted by a signal.
I believe this to be POSIX-compliant, since POSIX mentions the rmtp
parameter only in the paragraph about EINTR. This is also what
Linux does. (NetBSD updates rmtp unconditionally.)
Copy the whole nanosleep.2 man page from NetBSD because it is complete
and closely resembles the POSIX description. Edit, polish, and reword it
a bit, being sure to keep any relevant text from the FreeBSD page.
