H A Dmsg_215.c1.11 Sun Aug 29 17:01:27 GMT 2021 rillig lint: in C99 mode, make implicit function declarations an error

In tree.c 1.294 from 2021-06-28, I had already tried this, but at that
time, there were too many implicit function definitions in the NetBSD
tree. Most of them were GCC builtins, which lint did not recognize.
Therefore I had to revert to a warning in tree.c 1.302 from 2021-06-30.

In the meantime, lint has learnt to recognize compiler builtins, see
is_compiler_builtin, so try again now. The build logs from x86_64,
i386, sparc and sparc64 show no more implicit function declarations.

H A Dsystm.h1.302 Mon May 22 14:07:24 GMT 2023 riastradh uiomove(9): Add uiopeek/uioskip operations.

This allows a caller to grab some data, consume part of it, and
atomically update the uio with only the amount it consumed. This
way, the caller can use a buffer of a size that doesn't depend on how
much it will actually consume, which it may not know in advance --
e.g., because it depends on how much an underlying hardware tty
device will accept before it decides it has had too much.

Proposed on tech-kern:
https://mail-index.netbsd.org/tech-kern/2023/05/09/msg028883.html

(Opinions were divided between `uioadvance' and `uioskip'. I stuck
with `uioskip' because that was less work for me.)

H A Dvnode.h1.302 Mon Jul 18 04:30:30 GMT 2022 thorpej Make kqueue event status for vnodes shareable, and for stacked file systems
like nullfs, make the upper vnode share that status with the lower vnode.

And, lo, NetBSD 9.99.99.

H A Dtty.c1.302 Mon Oct 03 19:57:06 GMT 2022 riastradh constty(4): Make MP-safe.

Access to the global constty variable is coordinated as follows:

1. Setting constty to nonnull, with atomic_store_release, is allowed
only under the new adaptive constty_lock in thread context. This
serializes TIOCCONS operations and ensures unlocked readers can
safely use a constty pointer read with atomic_load_consume.

2. Changing constty from nonnull to null, with atomic_cas_ptr, is
allowed in any context -- printf(9) uses this to disable a broken
constty.

3. Reading constty under constty_lock is allowed with
atomic_load_relaxed, because while constty_lock is held, it can
only be made null by some other thread/CPU, never made nonnull.

4. Reading constty outside constty_lock is allowed with
atomic_load_consume in a pserialize read section -- constty is
only ever made nonnull with atomic_store_release, in (1).
ttyclose will wait for all these pserialize read sections to
complete before flushing the tty.

5. To continue to use a struct tty pointer in (4) after the
pserialize read section has completed, caller must use tty_acquire
during the pserialize read section and then tty_release when done.
ttyclose will wait for all these references to drain before
returning.

These access rules allow us to serialize TIOCCONS, and safely destroy
ttys, without putting any locks on the access paths like printf(9)
that use constty. Once we set D_MPSAFE, operations on /dev/console
will contend only with other users of the same tty as constty, which
will be an improvement over contending with all other kernel lock
users in the system.
H A Dvfs_bio.c1.302 Wed Mar 30 10:34:14 GMT 2022 riastradh kern: Sprinkle biglock-slippage assertions.

We seem to have a poltergeist that occasionally messes with the
biglock depth, but it's very hard to reproduce and only manifests as
some other CPU spinning out on the kernel lock which is no good for
diagnostics.

Remove separate mb_map. The nmbclusters is computed at boot time based
on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.

The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048
clusters.

Fix use-after-free on failed unmount with extended attribute enabled

When unmount failed, for instance because the mount is still busy,
UFS1 extended attributes structures were left freed while the kernel
assumes extended attributes were still enabled. This led to using
UFS1 extended attributes structures after free. With LOCKDEBUG, with
quickly triggers a panic.

The problem is fixed by:
1) clear MNT_EXTATTR flag after extended attributes structures are freed
2) attempt to restart extended attributes after failed unmount
2) set MNT_EXTATTR correctly after extended attributes restart

As a side effect, extended attribute structures are now only initialized
when extended attributes are started for the filesystem.
