H A Dbuild.sh1.392 Sat May 10 14:10:57 GMT 2025 martin Expert hack: if you know what you are doing, allow to avoid
the tool build for some commands that might or might not need
it, like:

build.sh -VUSETOOLS=never -P mkrepro-timestamp show-revisionid

This will not need any tools when run on a new-enough NetBSD host or
if using some other VCS than CVS.

H A Dwd.c1.392 Thu Feb 02 19:43:02 GMT 2012 tls branches: 1.392.2;
Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.

H A DMakefile1.392 Mon Aug 22 18:54:05 GMT 2011 jym branches: 1.392.2;
Modify etc/defaults/Makefile so that architectures can specify an additional
rc.conf file. This one should reside under etc/etc.${MACHINE}/, and will
get automatically appended to etc/defaults/rc.conf at build time if present.

This is used by i386 and amd64 to append a small MD rc.conf(5) configuration
at the end of the defaults/rc.conf file, so that powerd(8) can be started
by default when we are running in a Xen environment. This is needed to support
save/restore functions for domains.

From all the alternatives proposed to fix that issue (from /etc/rc.conf
parsing in postinstall to etc/defaults/rc.conf arch-hooks) I believe
this one will appease everyone because it:
- does not touch etc/defaults/rc.conf template file,
- patches it at build time for MD hooks only when required,
- does not need to parse/modify a user-specified file like /etc/rc.conf (which
is a complex, error-prone operation),
- only enables powerd(8) by default when conditions are met (Xen environment)
while still allowing root to shoot himself in the foot if he wants to
override this manually in /etc/rc.conf.

H A Duvm_map.c1.392 Sat Mar 12 15:32:33 GMT 2022 riastradh sys: Membar audit around reference count releases.

If two threads are using an object that is freed when the reference
count goes to zero, we need to ensure that all memory operations
related to the object happen before freeing the object.

Using an atomic_dec_uint_nv(&refcnt) == 0 ensures that only one
thread takes responsibility for freeing, but it's not enough to
ensure that the other thread's memory operations happen before the
freeing.

Consider:

Thread A Thread B
obj->foo = 42; obj->baz = 73;
mumble(&obj->bar); grumble(&obj->quux);
/* membar_exit(); */ /* membar_exit(); */
atomic_dec -- not last atomic_dec -- last
/* membar_enter(); */
KASSERT(invariant(obj->foo,
obj->bar));
free_stuff(obj);

The memory barriers ensure that

obj->foo = 42;
mumble(&obj->bar);

in thread A happens before

KASSERT(invariant(obj->foo, obj->bar));
free_stuff(obj);

in thread B. Without them, this ordering is not guaranteed.

So in general it is necessary to do

membar_exit();
if (atomic_dec_uint_nv(&obj->refcnt) != 0)
return;
membar_enter();

to release a reference, for the `last one out hit the lights' style
of reference counting. (This is in contrast to the style where one
thread blocks new references and then waits under a lock for existing
ones to drain with a condvar -- no membar needed thanks to mutex(9).)

I searched for atomic_dec to find all these. Obviously we ought to
have a better abstraction for this because there's so much copypasta.
This is a stop-gap measure to fix actual bugs until we have that. It
would be nice if an abstraction could gracefully handle the different
styles of reference counting in use -- some years ago I drafted an
API for this, but making it cover everything got a little out of hand
(particularly with struct vnode::v_usecount) and I ended up setting
it aside to work on psref/localcount instead for better scalability.

I got bored of adding #ifdef __HAVE_ATOMIC_AS_MEMBAR everywhere, so I
only put it on things that look performance-critical on 5sec review.
We should really adopt membar_enter_preatomic/membar_exit_postatomic
or something (except they are applicable only to atomic r/m/w, not to
atomic_load/store_*, making the naming annoying) and get rid of all
the ifdefs.
