ChangeLog since bmake-20230126
* VERSION (_MAKE_VERSION): 20230208
Merge with NetBSD make, pick up
o var.c: always use SCOPE_GLOBAL for :_ to avoid problems
when it has been used within conditional expressions
* install-sh: if making directories ensure umask is set
to match mode.
* Makefile: use DIRMODE for directories and
NONBINMODE for man pages and mk files
Split the in_pcblookup_hash_locked() function into several independent
subroutine calls, each of which does some kind of hash table lookup.
This refactoring makes it easier to introduce variants of the lookup
algorithm that behave differently depending on whether they are
synchronized by SMR or the PCB database hash lock.
While here, do some related cleanup:
- Remove an unused ifnet parameter from internal functions. Keep it in
external functions so that it can be used in the future to derive a v6
scopeid.
- Reorder the parameters to in_pcblookup_lbgroup() to be consistent with
the other lookup functions.
- Remove an always-true check from in_pcblookup_lbgroup(): we can assume
that we're performing a wildcard match.
No functional change intended.

These changes unbreak AP startup when using a 13.1-RELEASE bhyve
executable with a newer kernel:
- Correct the destination mask for the VM_EXITCODE_IPI message generated
by an INIT or STARTUP IPI in vlapic_icrlo_write_handler().
- Only initialize vlapics on active vCPUs. 13.1-RELEASE bhyve activates
AP vCPUs only after the BSP starts them with an IPI, and vmm now
allocates vcpu structures lazily, so the STARTUP handling in
vm_handle_ipi() could trigger a page fault.
- Fix an off-by-one setting the vcpuid in a VM_EXITCODE_SPINUP_AP
message.

This allows us to avoid spurious calls to ktls_disable_ifnet()
When we implemented ifnet kTLSe, we set a flag in the tx socket
buffer (SB_TLS_IFNET) to indicate ifnet kTLS. This flag meant that
now, or in the past, ifnet ktls was active on a socket. Later,
I added code to switch ifnet ktls sessions to software in the case
of lossy TCP connections that have a high retransmit rate.
Because TCP was using SB_TLS_IFNET to know if it needed to do math
to calculate the retransmit ratio and potentially call into
ktls_disable_ifnet(), it was doing unneeded work long after
a session was moved to software.
This patch carefully tracks whether or not ifnet ktls is still enabled
on a TCP connection. Because the inp is now embedded in the tcpcb, and
because TCP is the most frequent accessor of this state, it made sense to
move this from the socket buffer flags to the tcpcb. Because we now need
reliable access to the tcbcb, we take a ref on the inp when creating a tx
ktls session.
While here, I noticed that rack/bbr were incorrectly implementing
tfb_hwtls_change(), and applying the change to all pending sends,
when it should apply only to future sends.
This change reduces spurious calls to ktls_disable_ifnet() by 95% or so
in a Netflix CDN environment.

GCC expands the pointer type in this conditional expression even for
template types _Up that are not arrays. This raises an error when
std::decay<> is used with reference types (as is done in LLVM's
sources). Using add_pointer<> causes GCC to only instantiate a

changes) has been merged to libc++ in commit

Overall, this is a non-functional change, except for kernels built with
SCHED_STATS. However, the switch types are useful for communicating the
intent of the caller.
1. Ensure that every caller provides a type. In most cases, we upgrade
the basic yield to sched_relinquish() aka SWT_RELINQUISH.
2. The case of sched_bind() is distinct, so add a new switch type SWT_BIND.
3. Remove the two unused types, SWT_PREEMPT and SWT_SLEEPQTIMO.
4. Remove SWT_NONE altogether and assert that callers always provide
a type flag.
5. Reference the mi_switch(9) man page in the comments, as these flags
will be documented there.

Currently isolation and resource requirements are handled directly
by the kyua runner, based on the requirements specified by the test.
It works well for simple tests, but may cause discrepancy with tests
doing complex pre-setups. For example, all tests that perform
VNET setups require root access to properly function.
This change adds additional handling of the "require_user" property
within the python testing framework. Specifically, it requests
root access if the test class signals its root requirements and
drops privileges to the desired user after performing the pre-setup.

asomers@ found a problem with the NFS client, where a write to
an NFS mounted file done via mmap(2) was lost when fspacectl(2)
was done before it. This turned out to be caused by clearing the
dirty bit on pages when the client was doing commit RPCs,
due to the second argument to vfs_busy_pages() being set to 1.
Commit RPCs tell the server to commit previously written data to
stable storage. However, Commit RPCs do not write data from the
client to the server. As such, if the dirty bit on the page has
been set by a mmap'd write to an address in the page, it should
not be cleared. Clearing it causes the mmap'd write to by lost.
This patch fixes the problem by changing the 2nd argument to
vfs_busy_pages() to 0 for this case.
I doubt this bug has affected many, since it was inherited from
the old NFS client and was in 4.3 FreeBSD twenty years ago.
Although fspacectl(2) is FreeBSD 14 specific, a write(2) would
cause the same failure.

The architecture nexus should handle allocation and release of memory and
interrupts. This is to ensure that system-wide resources such as these
are available to all devices, not just children of ofwbus0.
On powerpc this moves the ownership of these resources up one level,
from ofwbus0 to nexus0. Other architectures already have the required
logic in their nexus implementation, so this eliminates the duplication
of resources. An implementation of nexus_adjust_resource() is added for
arm, arm64, and riscv.
As noted by ian@ in the review, resource handling was the main bit of
logic distinguishing ofwbus from simplebus. With some attention to
detail, it should be possible to merge the two in the future.
