In the rare case that we succeed in probing, but fail to attach, flip
the default to be to disable the

the old behavior. The old behavior dates form a time when dynamic
control of devices wasn't yet present (devctl didn't exist). Now that
one can retry probe/attach the device with devctl, the default doesn't
make sense: The more desirable behaivor is to have stable device numbers
when one has several instances of the same device in a system (common
for NICs or HBAs).

Reported by: avg
Discussed with: glebius, avg
RFC: 8375, Section 6: Security Considerations
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.

A number of header files in sys/* have, going back to 7th Edition Unix
in 1979, reqiured other files (like sys/types.h) to compile. Likewise
the 4BSD networking code has had prerequisites. However, going back to
around the turn of the 21st century, other systems have made them be
independently include-able (wide-spread header include protection
post-dates 7th edition Unix by maybe 3 or so years judging from USENET
source postings). Start down the path of making them all independently
include-able by creating this test that fails buildworld when they are
not.
The file 'badfiles.inc' contains a list of the currently broken files
that cannot be included w/o any prerequisites. As files are fixed, 'make
badfiles.inc' should be re-run to remove them from the list. Note: All
files that start with an underscore are considered internal and not
tested.
Please note: once a file is removed from badfiles.inc, it must pass on
all architectures. Buildworld through at least the _includes target is
needed to ensure its working (though a buildkernel should also be done
on all architectures as well).

NOTE: HEADS UP read the note below if your kernel config is not including GENERIC!!
This patch does a bit of cleanup on TCP congestion control modules. There were some rather
interesting surprises that one could get i.e. where you use a socket option to change
from one CC (say cc_cubic) to another CC (say cc_vegas) and you could in theory get
a memory failure and end up on cc_newreno. This is not what one would expect. The
new code fixes this by requiring a cc_data_sz() function so we can malloc with M_WAITOK
and pass in to the init function preallocated memory. The CC init is expected in this
case *not* to fail but if it does and a module does break the
"no fail with memory given" contract we do fall back to the CC that was in place at the time.
This also fixes up a set of common newreno utilities that can be shared amongst other
CC modules instead of the other CC modules reaching into newreno and executing
what they think is a "common and understood" function. Lets put these functions in
cc.c and that way we have a common place that is easily findable by future developers or
bug fixers. This also allows newreno to evolve and grow support for its features i.e. ABE
and HYSTART++ without having to dance through hoops for other CC modules, instead
both newreno and the other modules just call into the common functions if they desire
that behavior or roll there own if that makes more sense.
Note: This commit changes the kernel configuration!! If you are not using GENERIC in
some form you must add a CC module option (one of CC_NEWRENO, CC_VEGAS, CC_CUBIC,
CC_CDG, CC_CHD, CC_DCTCP, CC_HTCP, CC_HD). You can have more than one defined
as well if you desire. Note that if you create a kernel configuration that does not
define a congestion control module and includes INET or INET6 the kernel compile will
break. Also you need to define a default, generic adds 'options CC_DEFAULT=\"newreno\"
but you can specify any string that represents the name of the CC module (same names
that show up in the CC module list under net.inet.tcp.cc). If you fail to add the
options CC_DEFAULT in your kernel configuration the kernel build will also break.

The last two drivers that required sppp are cp(4) and ce(4).
These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.
Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially. Later they have dropped
support for Linux drivers to. As of mid-2020 they don't even
have a developer to maintain their Windows driver. However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.
These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP. Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.
Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part. Further maintenance of these
drivers in the tree shouldn't be a big deal.
While doing that, remove some cruft and enable cp(4) compilation
on amd64. The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.

GDB 6.1.1 was released in June 2004 and is long obsolete. It does not
support all of the architectures that FreeBSD does, and imposes
limitations on the FreeBSD kernel build, such as the continued use of
DWARF2 debugging information.
It was kept (in /usr/libexec/) only for use by crashinfo(8), which
extracts some basic information from a kernel core dump after a crash.
Crashinfo already prefers gdb from port/package if installed.
Future work may add kernel debug support to LLDB or find another path
for crashinfo's needs, but in any case we do not want to ship the
excessively outdated GDB in FreeBSD 13.
