This hasn't been updated in 10 years in any real way. It's time to
retire it. It hasn't worked in some time due to drivers being removed
starting in FreeBSD 10. All the interesting bits have already been
hoisted into other parts of base. The google code site hasn't had any
commits since 2011 and claims to Target FreeBSD 5, 6, 7, and 8.
Should someone fix the numerous issues, it can be restored.

parseDWM() can advance the time to the next week. If the next week is
in the next month, then tm_mon is incremented. However, the increment
was failing to handle the wraparound from December to January, so when
parsing a rule during the last week of the December, the month would
advance to month 12. This triggered an out-of-bounds read of the
mtab[] array in days_pmonth() after parseDWM() returned. To fix,
this change resets the month to January and increment the year when
the month increment wraps.
The default rule for /var/log/weekly.log triggers this during the
last week of December each year.

If desired we can stop linking devd statically after this change (to

We must set SHLIBDIR with ?= before including <src.opts.mk>, otherwise
that will have set SHBLIDIR to its default value of /usr/lib.
Otherwise, "make delete-old-libs" would suggest to delete libc++.so.1
from /usr/lib, while there was not yet a copy in /lib.

The introduction of <sched.h> improved compatibility with some 3rd
party software, but caused the configure scripts of some ports to
assume that they were run in a GLIBC compatible environment.
Parts of sched.h were made conditional on -D_WITH_CPU_SET_T being
added to ports, but there still were compatibility issues due to
invalid assumptions made in autoconfigure scripts.
The differences between the FreeBSD version of macros like CPU_AND,
CPU_OR, etc. and the GLIBC versions was in the number of arguments:
FreeBSD used a 2-address scheme (one source argument is also used as
the destination of the operation), while GLIBC uses a 3-adderess
scheme (2 source operands and a separately passed destination).
The GLIBC scheme provides a super-set of the functionality of the
FreeBSD macros, since it does not prevent passing the same variable
as source and destination arguments. In code that wanted to preserve
both source arguments, the FreeBSD macros required a temporary copy of
one of the source arguments.
This patch set allows to unconditionally provide functions and macros
expected by 3rd party software written for GLIBC based systems, but
breaks builds of externally maintained sources that use any of the
following macros: CPU_AND, CPU_ANDNOT, CPU_OR, CPU_XOR.
One contributed driver (contrib/ofed/libmlx5) has been patched to
support both the old and the new CPU_OR signatures. If this commit
is merged to -STABLE, the version test will have to be extended to
cover more ranges.
Ports that have added -D_WITH_CPU_SET_T to build on -CURRENT do
no longer require that option.
The FreeBSD version has been bumped to 1400046 to reflect this
incompatible change.

For years CTL block backend limited I/O size to 1MB, splitting larger
requests into sequentially processed chunks. It is sufficient for
most of use cases, since typical initiators rarely use bigger I/Os.
One of known exceptions is VMWare VAAI offload, by default sending up
to 8 4MB EXTENDED COPY requests same time. CTL internally converted
those into 32 1MB READ/WRITE requests, that could overwhelm the block
backend, having finite number of processing threads and making more
important interactive I/Os to wait in its queue. Previously it was
partially covered by CTL core serializing sequential reads to help
ZFS speculative prefetcher, but that serialization was significantly
relaxed after recent ZFS improvements.
With the new settings block backend receives 8 4MB requests, that
should be easier for both CTL itself and the underlying storage.

Text requests and responses can span multiple PDUs. In that case, the
sender sets the Continue bit in non-final PDUs and the Final bit in
the last PDU. The receiver responds to non-final PDUs with an empty
text PDU.
To support this, add a more abstract API in libiscsi which accepts and
receives key sets rather than PDUs. These routines internally send or
receive one or more PDUs. Use these new functions to replace the
handling of TextRequest and TextResponse PDUs in discovery sessions in
both ctld and iscsid.
Note that there is not currently a use case for large Text requests
and those are still always sent as a single PDU. However, discovery
sessions can return a text response listing targets that spans
multiple PDUs, so the new API supports sending and receiving multi-PDU
responses.
