Simply said, WDAT is an abstraction for the real WDT hardware. For
instance, to add a newer generation WDT to ichwd(4), one must know the
detailed hardware registers, etc..
With WDAT, the necessary IO accesses to operate the WDT are comprehensively
described in it and no hardware knowledge is required.
With this driver, the WDT on Advantech ARK-1124C, Dell R210 and Dell R240 are
detected and operated flawlessly.
* While R210 is also supported by ichwd(4), others are not supported yet.
The unfortunate thing is that not all systems have WDAT defined.

SAM-5 specification states maximum size of command identifier (tag),

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

This changes CTL ABI and HA protocol, so CTL_HA_VERSION is bumped.

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
coverage of all possible scenarios of receiving SYN in TIME_WAIT.

The maximum CPU number of a cpuset_t is determined by CPU_SETSIZE. In
the kernel this is MAXCPU, but in userspace it is CPU_MAXSIZE unless
CPU_SETSIZE is defined before including sys/_cpuset.h. CPU_MAXSIZE is
256 and in userspace MAXCPU is generally 1 because it being set to a
larger MD value is gated on SMP being defined (not generally the case in
userspace).

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.

FreeBSD used to support both armv4 and armv5 binaries. All of that
support has been removed from the tree. We have only ever supported
armv6 and armv7 binaries in that mode. Note armv4 here too for
completeness since it flowed better than 'armv5 and earlier' and means
the same thing (FreeBSD never ran on an armv3 or earlier CPU).

For small, transactional exchanges (e.g. web objects <15kB), this

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.

Alternatively a user can save the state of the /var/run directories
manually using service var_run save and disable the autosaving of

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.
