SAM-5 specification states maximum size of command identifier (tag),
defined by specific transports, should not be larger than 64 bits.
While most of supported transports use 32 bits or less, it was
reported that virtio-scsi uses 64 bits. Truncation to 32 bits in
bhyve code caused false tag conflict errors reported and possibly
other issues.
This changes CTL ABI and HA protocol, so CTL_HA_VERSION is bumped.
While we make HA protocol incompatible, increase default maximum
number of ports in CTL from 256 to 1024, matching number of LUNs.
There are many reports from people who need many iSCSI targets with
only one LUN each. Increased memory consumption should be less of
a problem these days.

GCC 12 raises warnings about literal operator suffixes not preceded by

Netlink has a confirmation/error reporting mechanism for the sent
messages. Kernel explicitly acks each messages if requested (NLM_F_ACK)
or if message processing results in an error.
Similarly, for multipart messages - typically dumps, where each message
represents a single object like an interface or a route - another
message, NLMSG_DONE is used to indicate the end of dump and the
resulting status.
As a result, successfull dump ends with both NLMSG_DONE and NLMSG_ERROR
messages.
RFC 3549 does not say anything specific about such case.
Linux adopted an optimisation which suppresses NLMSG_ERROR message
when NLMSG_DONE is already sent. Certain libraries/applications like
libnl depends on such behavior.
Suppress sending NLMSG_ERROR if NLMSG_DONE is already sent, by
setting newly-added 'suppress_ack' flag in the writer and checking
this flag when generating ack.
This change restores libnl compatibility.

The suppresion was added in 5f311da2cc with no explanation in the
commit message of the exact problem that was fixed. In the BSDCan
2006 talk [1], slides 12 to 14, we can find that it seems that there
was some problem with the TIME_WAIT state not properly being handled
on the remote side (also FreeBSD!), and this switching off the
suppression had hidden the problem. The rationale of the change was
that other stacks may also be buggy wrt the TIME_WAIT.
I did not find the actual problem in TIME_WAIT that the suppression
has hidden, neither a commit that would fix it. However, since that
time we started to handle SYNs with RFC5961 instead of RFC793, see
3220a2121c. We also now have the tcp-testsuite [2], that has full

RB-tree augmentation maintains data in each node of the tree that
represents the product of some associative operator applied to all the
nodes of the subtree rooted at that node. If a node in the tree
changes, augmentation data for the node is updated for that node and
all nodes on the path from that node to the tree root. However,
sometimes, augmenting a node changes no data in that node,
particularly if the associated operation is something involving 'max'
or 'min'. If augmentation changes nothing in a node, then the work of
walking to the tree root from that point is pointless, because
augmentation will change nothing in those nodes either. This change
makes it possible to avoid that wasted work.
Define RB_AUGMENT_CHECK as a macro much like RB_AUGMENT, but which
returns a value 'true' when augmentation changes the augmentation data
of a node, and false otherwise. Change code that unconditionally walks
and augments to the top of tree to code that stops once an
augmentation has no effect. In the case of rebalancing the tree after
insertion or deletion, where previously a node rotated into the path
was inevitably augmented on the march to the tree root, now check to
see if it needs augmentation because the march to the tree root
stopped before reaching it.
Change the augmentation function in iommu_gas.c so that it returns
true/false to indicate whether the augmentation had any effect.

kern.cam.da.default_softtimeout currently does nothing. It sets a value
in the CCB that SIMs could look at, only none do. Leave it undocumented
until it actually does something. It was introduced to allow a 'soft
recovery' to be started when things were taking too long in the SIM by
not scheduling new I/O, or other measures the SIM knew would help when
it seemed like things were getting 'backed up'. No SIM in the FreeBSD
tree implements this and scsi_da doesn't use it other than to pass it
down, so best remove it from the documentation until it does something.

Here go cons of using inpcb for divert:
- divert(4) uses only 16 bits (local port) out of struct inpcb,
which is 424 bytes today.
- The inpcb KPI isn't able to provide hashing for divert(4),
thus it uses global inpcb list for lookups.
- divert(4) uses INET-specific part of the KPI, making INET
a requirement for IPDIVERT.
Maintain our own very simple hash lookup database instead. It
has mutex protection for write and epoch protection for lookups.
Since now so->so_pcb no longer points to struct inpcb, don't
initialize protosw methods to methods that belong to PF_INET.
Also, drop support for setting options on a divert socket. My
review of software in base and ports confirms that this has no
use and unlikely worked before.
Differential revision: https://reviews.freebsd.org/D36382
The divert(4) is not a protocol of IPv4. It is a socket to
intercept packets from ipfw(4) to userland and re-inject them
back. It can divert and re-inject IPv4 and IPv6 packets today,
but potentially it is not limited to these two protocols. The
IPPROTO_DIVERT does not belong to known IP protocols, it
doesn't even fit into u_char. I guess, the implementation of
divert(4) was done the way it is done basically because it was
easier to do it this way, back when protocols for sockets were
intertwined with IP protocols and domains were statically
compiled in.
Moving divert(4) out of inetsw accomplished two important things:
1) IPDIVERT is getting much closer to be not dependent on INET.
This will be finalized in following changes.
2) Now divert socket no longer aliases with raw IPv4 socket.
Domain/proto selection code won't need a hack for SOCK_RAW and
multiple entries in inetsw implementing different flavors of
raw socket can merge into one without requirement of raw IPv4
being the last member of dom_protosw.

Generally, access to the kernel debugger is considered to be unsafe from
a security perspective since it presents an unrestricted interface to
inspect or modify the system state, including sensitive data such as
signing keys.
However, having some access to debugger functionality on production
systems may be useful in determining the cause of a panic or hang.
Therefore, it is desirable to have an optional policy which allows
limited use of ddb(4) while disabling the functionality which could
reveal system secrets.
This loadable MAC module allows for the use of some ddb(4) commands
while preventing the execution of others. The commands have been broadly
grouped into three categories:
- Those which are 'safe' and will not emit sensitive data (e.g. trace).
Generally, these commands are deterministic and don't accept
arguments.
- Those which are definitively unsafe (e.g. examine <addr>, search
<addr> <value>)
- Commands which may be safe to execute depending on the arguments
provided (e.g. show thread <addr>).
Safe commands have been flagged as such with the DB_CMD_MEMSAFE flag.
Commands requiring extra validation can provide a function to do so.
For example, 'show thread <addr>' can be used as long as addr can be
checked against the system's list of process structures.
The policy also prevents debugger backends other than ddb(4) from
executing, for example gdb(4).

This fixes incomplete commit 2e547442ab
New sysctl allows to mark transmitted PPPoE LCP Control
ethernet frames with needed 3-bit Priority Code Point (PCP) value.
Confirming driver like if_vlan(4) uses the value to fill
IEEE 802.1p class of service field.
This is similar to Cisco IOS "control-packets vlan cos priority"
command.
It helps to avoid premature disconnection of user sessions
due to control frame drops (LCP Echo etc.)
if network infrastructure has a botteleck at a switch
or the xdsl DSLAM.

Get amd64 compiling. However, the current kboot supports an old way of
enumerating memory and the new way needs to be incorporated as well. The
powerpc folks could use either, it seems and newer powerpc platforms
need some changes for kboot to work anyway.
This commit includes the linker script, trampoline code to start the new
kernel, Linux system calls and the necessary configuration glue needed
to build the binaries.
This includes a quick hack to get multiboot support, but we need to
really share these defines. The multiiboot2.h is the minimum needed to
build. We have multiboot information in three places now, so a
refactoring is in order.
This should be considered, at best, preliminary and experimental for
anybody wishing to try it out.

This argument is useless for the vast majority of drivers. For now,
use __VA_ARGS__ wrapper macros so that that the *DRIVER_MODULE()
macros accept both the old version (with a devclass) and the new
version (which omits the argument and stores NULL in the
driver_module_data structure). This provides an API compatiblity
shim that can be merged to older stable branches.
Once all drivers relevant to 14.0 (both in and out of tree) have been
updated, the API compat shims can be dropped.

This dumper can instantiate and write the dump's contents to a
file-backed vnode.
Unlike existing disk or network dumpers, the vnode dumper should not be
invoked during a system panic, and therefore is not added to the global
dumper_configs list. Instead, the vnode dumper is constructed ad-hoc
when a live dump is requested using the new ioctl on /dev/mem. This is
similar in spirit to a kgdb session against the live system via
/dev/mem.
As described briefly in the mem(4) man page, live dumps are not
guaranteed to result in a usuable output file, but offer some debugging
value where forcefully panicing a system to dump its memory is not
desirable/feasible.
A future change to savecore(8) will add an option to save a live dump.

In order to support various types of data stored in device
tree properties or ACPI _DSD packages, create a new enum so
the caller can specify the expected type of a property they
want to read, according to the binding. The bus logic will use
that information to process the underlying data.
For example in DT all integer properties are stored in BE format.
In order to get constant results across different platforms we
need to convert its endianness to match the host.
Another example are ACPI_TYPE_INTEGER properties stored
as uint64_t. Before this patch the ACPI logic would refuse
to read them if the provided buffer was smaller than 8 bytes.
Now this can be handled by using DEVICE_PROP_UINT32 type.
Modify the existing consumers of this API to reflect the changes
and update the man pages accordingly.

During distributeworld we call distribute on subdirectories, which in
turn calls installconfig. However, this recursive installconfig call
appends the distribution name (in these cases, "base") to DESTDIR. For
install(1) this works fine as its -D argument comes from the top-level
Makefile.inc1, which passes the original DESTDIR, thereby resulting in
the METALOG entry having the distribution name as a prefix representing
its true installed path relative to the root, but for the hand-rolled
entries they do not use install(1) and thus do not have access to what
the original DESTDIR was, resulting in the METALOG missing this prefix.
Thus, pass down the name of the distribution via a new variable DISTBASE
(chosen as Makefile.inc1 already uses that to convey this exact same
information to etc's distrib-dirs during distributeworld) and prepend
this to the handful of manually-generated METALOG entries. For the
installworld case this variable will be empty and so this behaves as
before.
Note that we need to be careful to avoid double slashes in the METALOG;
distributeworld uses find | awk to split the single METALOG up into
multiple dist.meta files, and this relies on the paths in the METALOG
having the exact prefix ./dist (or ./dist/usr/lib/debug).
