- sc_tx_lock covers any access to tx list, tx ring, and writes to
if_flags and if_itimer
- sc_rx_lock covers any access to rx list, tx ring, and free tx counter
fix suspend and detach to work again - recent softintr changes made
xennet_tx_complete() not actually being called, because the call
in xennet_handler() was after IFF_RUNNING check; now it's called
directly rather than triggering softint, with updates locking it's safe
enable DVF_DETACH_SHUTDOWN for xennet(4), though the call only
triggers notification to backend to close, leaves actual detach to
xenwatch_thread
Relying on p_opptr is not safe as there is a race between:
- spawner giving a birth to a child process and being killed
- spawnee accessng p_opptr and reporting TRAP_CHLD

- Always print the core's vendor and product name.
- Print the CPU ID on the same line as the name. Single line of dmesg
per core.
- Use aprint_verbose for reporting additional details.
*) Revert the change of EOF detection while reading in libssl to avoid
regressions in applications depending on the current way of reporting
the EOF. As the existing method is not fully accurate the change to
reporting the EOF via SSL_ERROR_SSL is kept on the current development
branch and will be present in the 3.0 release.

*) Revised BN_generate_prime_ex to not avoid factors 3..17863 in p-1
when primes for RSA keys are computed.
Since we previously always generated primes == 2 (mod 3) for RSA keys,
the 2-prime and 3-prime RSA modules were easy to distinguish, since
N = p*q = 1 (mod 3), but N = p*q*r = 2 (mod 3). Therefore fingerprinting
2-prime vs. 3-prime RSA keys was possible by computing N mod 3.
This avoids possible fingerprinting of newly generated RSA modules.

same way as OpenBSD.
The use of coherent (uncacheable on ARM and other arches) mappings
for transfer buffers impacts performance, espcially where memcpys
are involved.
Audit the necessary usb_syncmem operations - a few were missing.
- Merge the eventswitch parent notification code which was copied in two
places (eventswitchchild)
- Fix bugs in the eventswitch parent notification code:
1. p_slflags should be accessed holding both proc_lock and p->p_lock
2. p->p_opptr can be NULL if the parent was PSL_CHTRACED and exited.
Fixes random crashes the posix_spawn_kill_spawner unit test which tried
to dereference a NULL pptr.
rx-copy (first shipped in NetBSD 6.0 in 2012) the only supported
mode
this is mostly to simplify maintenance and future development
rx-flip is not supported by Linux Dom0/DomU, and NetBSD Dom0/DomU
defaults to rx-copy for over 8 years now too, so there is little
need to keep the support for compatibility
besides compatibility there is no other reason to keep rx-flip -
page transfer is generally slower than copy due to necessary MMU/TLB
manipulation, especially on MP systems
0x60006003, which blocks SIGTERM by default, so running something simple
from a hook, like /etc/rc.d/racoon restart does not work. The script
is then stuck waiting for the daemon to die, which it won't since it will
never receive the signal, and the hook never terminates.
This logic is already present in subr_copy.c:copyin_vmspace() and
rumpcopy.c:copyinstr().
This avoids memcpy() calls for NULL objects that is Undefined Behavior,
allowed in the kernel space (-fno-delete-null-pointer-checks), but not
in userland.

Reading from a database is now optional.
Compiling terminfo descriptions (including from $TERMINFO) is now optional.
Compat support is now optional.
This removes 17k on amd64 from the binary size, which allows it to be used
again on space constrained ramdisks.
