[PATCH 0/8] ISDN patches for net-next

[Tilman Schmidt]

Karsten, David,

here's a series of eight patches to the Kernel CAPI subsystem and
the Gigaset driver. Please consider for application to net-next.
The first three should also go into -stable and are tagged accordingly.

Thanks,
Tilman

[PATCH 1/8] isdn/gigaset: ratelimit CAPI message dumps

[Tilman Schmidt]

Introduce a global ratelimit for CAPI message dumps to protect
against possible log flood.
Drop the ratelimit for ignored messages which is now covered by the
global one.

[PATCH 2/8] isdn/gigaset: fix CAPI disconnect B3 handling

[Tilman Schmidt]

If DISCONNECT_B3_IND was synthesized because of a DISCONNECT_REQ
with existing logical connections, the connection state wasn't
updated accordingly. Also the emitted DISCONNECT_B3_IND message
wasn't included in the debug log as requested.
This patch fixes both of these issues.

[PATCH 3/8] isdn/gigaset: improve error handling querying firmware version

[Tilman Schmidt]

An out-of-place "OK" response to the "AT+GMR" (get firmware version)
command turns out to be, more often than not, a delayed response to
a previous command rather than an actual error, so continue waiting
for the version number in that case.

[PATCH 8/8] isdn/capi: elliminate capincci_find() in non-middleware case

[Tilman Schmidt]

If Kernel CAPI is compiled without CONFIG_ISDN_CAPI_MIDDLEWARE,
the structure retrieved via capincci_find() is never actually
used, so don't compile that function in that case.

[PATCH 5/8] isdn/gigaset: internal function name cleanup

[Tilman Schmidt]

Functions clear_at_state and free_strings did the same thing;
drop one of them, keeping the more descriptive name.
Drop a redundant call.
Rename function dealloc_at_states to dealloc_temp_at_states
to clarify its purpose.

[PATCH 6/8] isdn/gigaset: unify function return values

[Tilman Schmidt]

Various functions in the Gigaset driver were using different
conventions for the meaning of their int return values.
Align them to the usual negative error numbers convention.

Re: [PATCH 1/8] isdn/gigaset: ratelimit CAPI message dumps

[Karsten Keil]

Hmm, I think the only CAPI messages which would need a ratelimit are
related to the DATA_B3 messages. If you need CAPI debug messages in most
cases you do not need all of the DATA_B3, but you do not want to miss
any other message related to the call control. With a general rate limit
you do not have the control, which messages are logged and which are not.
And here maybe some cases, when even the DATA_B3 are important (e.g.
searching bugs in flow control), so I would make it still conditional
to allow to print all messages.
And I'm not sure, if this is really something for stable.

The ratelimit introduced by this patch only applies to messages
other than DATA_B3. Logging DATA_B3 messages is not done via
dump_cmsg().

I'd like to ratelimit specifically non-DATA_B3 messages because I
saw a (possibly buggy) CAPI application flooding the log with
FACILITY messages. Equally important, I'd like to make the
ratelimit in do_nothing() / do_unsupported() bursty because I had
a case where I needed to see several ignored/unhandled CAPI
messages in quick succession. So this patch is killing two birds
with one stone for me.

The burst limit of 20 messages in 20 seconds is chosen to allow a
complete call setup sequence to be logged, while limiting to one
message per second in the long run.

DATA_B3 dumps produce an enormous amount of log data and are
therefore controlled separately by the DEBUG_MCMD flag.
Someone who enables that should know what she or he does.
But if you need them, you need them all. A ratelimit doesn't
make sense there in my experience.

It's pretty simple and localized, a net simplification, and only
affects generation of debugging messages, so I think it's safe.
But if you see a problem there I can drop the "CC: stable" line.

Thanks,
Tilman

Thanks for the clarification, forget about my objection.
I ack this patch now.

I let the decision about it to you and the stable maintainers.

Is there anything missing for these to be accepted into net-next?
Or should I just be patient?

I'll take care of it, I just put them back into "under review" state
in patchwork.

All applied and pushed out to net-next, thanks Tilman.
