bas_gigaset: fix pre_reset handling

2012-12-06T11:20:17+00:00

commit c6fdd8e5d0c65bb8821dc6da26ee1a2ddd58b3cc upstream.

The delayed work function int_in_work() may call usb_reset_device()
and thus, indirectly, the driver's pre_reset method. Trying to
cancel the work synchronously in that situation would deadlock.
Fix by avoiding cancel_work_sync() in the pre_reset method.

If the reset was NOT initiated by int_in_work() this might cause
int_in_work() to run after the post_reset method, with urb_int_in
already resubmitted, so handle that case gracefully.

isdn/gigaset: improve error handling querying firmware version

2012-05-30T23:43:24+00:00

commit e055d03dc088a990fe5ea24a2d64033a168da23c upstream.

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.

isdn/gigaset: fix CAPI disconnect B3 handling

2012-05-30T23:43:23+00:00

commit 62a1cfe052346b96a552b6a9178d412c709711bb upstream.

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.

isdn/gigaset: ratelimit CAPI message dumps

2012-05-30T23:43:23+00:00

commit 8e618aad5348b6e6c5a90e8d97ea643197963b20 upstream.

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.

isdn: avoid copying too long drvid

2011-11-29T23:39:37+00:00

"cfg->drvid" comes from the user so there is a possibility they
didn't NUL terminate it properly.

isdn: make sure strings are null terminated

2011-11-29T23:39:36+00:00

These strings come from the user.  We strcpy() them inside
cf_command() so we should check that they are NULL terminated and
return an error if not.
