7920ad944b libbe(3): Move build goop back out of cddl/
Some background: in the GSoC project, libbe/Makefile lived in lib/libbe. I
created projects/bectl branch, maintained the above for all of five
minutes before I misread Makefile.inc1 and decided that it couldn't possibly
build outside of cddl/, so I kicked the Makefile out into the cddl/ build
and all was good. The misreading was of the bit where .WAIT is added to
SUBDIR after lib, libexec but prior to building bin and cddl *only during
the install targets*, which is the critical part.

Fast forward- buildworld was still broken in my branch unbeknownst to me
because I didn't nuke my OBJDIR. Combing through Makefile.inc1 eventually
revealed the necessary magic to make sure that libbe's dependencies are
specified well enough, and it becomes clear what needs done to make a
non-cddl/ build work. This is an interesting prospect, because the build
split is kind of annoying to work with.

IGNORE_PRAGMA is added to avoid dropping WARNS by one more. This was
previously pulled in via cddl/Makefile.inc.

This basically adds makes use of the C99 restrict keyword, and also
adds some 'const's to four threading functions: pthread_mutexattr_gettype(),
pthread_mutexattr_getprioceiling(), pthread_mutexattr_getprotocol(), and
pthread_mutex_getprioceiling. The changes are in accordance to POSIX/SUSv4-2018.

284001a222 Put jail(2) under COMPAT_FREEBSD11. It has been the "old" way of creating
jails since FreeBSD 7.

Along with the system call, put the various security.jail.allow_foo and
security.jail.foo_allowed sysctls partly under COMPAT_FREEBSD11 (or
BURN_BRIDGES).  These sysctls had two disparate uses: on the system side,
they were global permissions for jails created via jail(2) which lacked
fine-grained permission controls; inside a jail, they're read-only
descriptions of what the current jail is allowed to do.  The first use
is obsolete along with jail(2), but keep them for the second-read-only use.

9d45c24cc4 Create a loader for each interpreter for x86 BIOS and all EFI
Create loader_{4th,lua,simp}{,.efi}. All of these are installed by
default. Create LOADER_DEFAULT_INTERP to specify the default
interpreter when no other is specified. LOADER_INTERP is the current
interpreter language building. Turn building of lua on by default to
match 4th. simploader is a simplified loader build w/o any interpreter
language (but with a simple loader).  This is the historic behavir you
got with WITHOUT_FORTH. Make a hard link to the default loader. This
has to be a hard link rather than the more desirable soft link because
older zfsboot blocks don't support symlinks.

3f48dbd1cc Merge libbe(3)/bectl(8) from projects/bectl into head
bectl(8) is an administrative interface for working with ZFS boot
environments, intended to provide a superset of the functionality provided
by sysutils/beadm.

libbe(3) is the back-end library that the required functionality has been
pulled out into for later reuse.

These were originally written for GSoC 2017 under the mentorship of
allanjude@.

bectl(8) has proven pretty stable in my testing, with the known bug
documented in the man page.

89edb881e6 Add optional LLVM BPF target support
BPF (eBPF) is an independent instruction set architecture which is
introduced in Linux a few years ago. Originally, eBPF execute
environment was only inside Linux kernel. However, recent years there
are some user space implementation (https://github.com/iovisor/ubpf,
https://doc.dpdk.org/guides/prog_guide/bpf_lib.html) and kernel space
implementation for FreeBSD is going on
(https://github.com/YutaroHayakawa/generic-ebpf).

The BPF target support can be enabled using WITH_LLVM_TARGET_BPF, as it
is not built by default.

95a914f631 Address concerns about CPU usage while doing TCP reassembly.
Currently, the per-queue limit is a function of the receive buffer
size and the MSS.  In certain cases (such as connections with large
receive buffers), the per-queue segment limit can be quite large.
Because we process segments as a linked list, large queues may not
perform acceptably.

The better long-term solution is to make the queue more efficient.
But, in the short-term, we can provide a way for a system
administrator to set the maximum queue size.

We set the default queue limit to 100.  This is an effort to balance
performance with a sane resource limit.  Depending on their
environment, goals, etc., an administrator may choose to modify this
limit in either direction.

87842989f8 Add ioctl to conveniently mmap a PCI device BAR into userspace.
Add the ioctl PCIOCBARMMAP on /dev/pci to conveniently create
userspace mapping of a PCI device BAR.  This is enormously superior to
read the BAR value with PCIOCREAD and then try to mmap /dev/mem, and
should allow to automatically activate the mapped BARs when needed in
future.

Current implementation creates new sg pager for each user mmap
request.  If the pointer (and reference) to a managed device pager is
stored in pci_map, we would be able to revoke all mappings on the BAR
deactivation or relocation.  This is related to the unimplemented BAR
activation on mmap, and is postponed for the future.
