Fix pcap-config --libs output

(martin)

Welcome to NetBSD 9.99.84 (bpf tracking changes)

(martin)

Add a bpf_register_track_event() function (and deregister equivalent)
that allows a driver to track listeners attaching/detaching from tap
points.

This is usefull for drivers that would have to do extra work for some
taps and can not easily decide (at the driver level) if the work would
be needed further up the stack.

An example is providing radiotap headers for IEEE 802.11 frames.

(martin)

Add a (FreeBSD compatible) bpf_peers_present() predicate to allow
testing for active listeners on a tap.

Work around abs rela relocations issue (for now):

0000000000000048 R_X86_64_64      *ABS*
...

Since those have symidx == 0, and the 0 symbol table entry is special,
treat them as SHN_ABS.

Change ENOENT -> ENOEXEC to avoid confusion (like other linking errors),
and add some debugging when that happens.

audio(4): Revert revision 1.96 and redo it another way.

Instead of refusing to open /dev/audioN for writes when the device
doesn't support playback, just refuse to issue writes.

Although it seems more sensible to me to reject writable opens early
on, and it seems Solaris does so, this makes querying device
properties a little trickier and is a change to the NetBSD semantics.

(riastradh)

pad(4): run the callout if the buffer is saturated instead of returning

reverts to the same behavior as in -8 and -9. prevents immediate failures
and device timeouts if there's a slight delay in the buffer being
consumed.

this is reproducible with the example in the man page that uses
ffmpeg to record the output of audioplay:

$ ffmpeg -f s16le -ar 44100 -ac 2 -i /dev/pad0 output.wav
$ audioplay -d /dev/audio1 input.wav

if output.wav already exists, ffmpeg will prompt for confirmation
to overwrite as soon as audioplay starts, causing a noticable delay,
followed by a write failure that causes audioplay to immediately
exit.

audio(4): When closing /dev/audioN, drain before removing from list.

Previously, in revision 1.100, I factored the SLIST_REMOVE out of
audio_unlink and audio_close up into audioclose since it is now used
by /dev/audio, /dev/audioctl, and /dev/mixer alike.  But I didn't
realize that the order

1. audio_track_drain
2. SLIST_REMOVE from sc_files

was significant; it matters because audio_track_drain waits for
wakeups that are delivered by hardware interrupts only to files
listed in sc_files.

This also fixes a bug introduced with the audiobell -- it was missing
the SLIST_REMOVE altogether.

For now, duplicate the SLIST_REMOVE calls in a few more places --
this is suboptimal but I want to make sure the logic works before
factoring it all out to tidy up.

Adapt the SMALLPROG / -UWITH_SSL build to also use the fetch_*()

Disable ssl-specific support in the fetch_*() methods if WITH_SSL

dev_verbose(9): Prohibit autounloading modules.

This logic is not safe for autounload right now -- there's no
mechanism by which to block new users and wait for existing users to
drain when unloading.  To be remedied!

x86: Reset cached tsc in every lwp to 0 on suspend/resume.

This avoids spuriously warning about tsc going backwards, which is to
be expected after a suspend/resume cycle.

audio(4): audio_unlink never fails, so make it return void.

(riastradh)

audio(4): Insert mixers and audioctls into sc_files on open too.

This is necessary so that on detach we set file->dying before any
operations, particularly audioclose, try to acquire a psref by the
time the audio softc is gone.

Candidate fix for PR kern/56164.

(riastradh)

audio(4): No need to set file->dying when closing the file.

No other file operations are possible by the time we get to
audioclose.

(riastradh)

audio(4): Grab sc->sc_cred under sc->sc_lock before freeing.

Otherwise we may race with open, leaking a cred no longer in use and
freeing a cred still in use.

(riastradh)

audio(4): Use kmem_alloc(sizeof(*p)) style.

(riastradh)

audio(4): Make sure to return ENXIO if device is being detached.

Don't return 0 indicating successful open of an unusable device!

(riastradh)

audio(4): Set AUMODE_PLAY/RECORD only if asked _and_ supported.

If one is requested and _not_ supported, fail; otherwise we might
enter audio_write with a null play track and crash on KASSERT.

(riastradh)

ksyms(4): Don't skip symbol tables that are soon to be freed.

They will not actually be freed until /dev/ksyms is closed, so
continued access to them remains kosher.

(riastradh)

ksyms(4): Modify ksyms_symtabs only at IPL_HIGH.

This limits the opportunities for ddb to witness an inconsistent
state of the symbol table list.

(riastradh)

ksyms(4): Fix ksymsread synchronization.

Fixes crash on concurrent update and read of /dev/ksyms.

XXX Unclear why we have to skip sd_gone entries here -- it seems like
they should be preserved until ksymsclose.

(riastradh)

audiorecord(1): Handle read(2) return value gracefully.

Pull up following revision(s) (requested by rin in ticket #1277):

sys/arch/aarch64/aarch64/netbsd32_machdep.c: revision 1.18

Fix conversion between aarch64 and aarch32 fpreg's; in aarch32 mode,
d0-d31 are packed into v0-v15 (== q0-q15).

This fixes crashes in VFP-optimized codes running on COMPAT_NETBSD32.

OK ryo

Pull up following revision(s) (requested by rin in ticket #1276):

external/mit/xorg/server/drivers/xf86-input-keyboard/Makefile: revision 1.17

Make wskbd(4) default for mac68k; no other protocol is available.

(martin)

Fix the wrong timeout event handler for PAP

sppp_auth_to_event() is a implementation of TO+/TO- event for
authentication protocol and it drops TO+ event in Ack-rcvd state.

(yamaguchi)

Update test case.
The state of IPCP and IPv6CP is Closed when those are disabled.

(yamaguchi)

Send Up event in tlu action of LCP

When LCP is stopping, the layer send Down event and Close event
(Down -> Close). To align the sequence, Up event is moved
before Open event.

(yamaguchi)

Added logs when IPCP and IPv6CP are up or down

(yamaguchi)

Added SPPP_LOG() for refactoring around log
