* Fix stack corruption during juju lock transactionsGravatar David Moore 2008-12-291-13/+19
| | | | | | | | | | | | | | | When performing a lock transaction (such as with fw_lock) under Juju, 4 bytes of the stack gets corrupted. This is because the lock transaction has 8 bytes of data sent and 4 bytes received. Since the transaction "length" is specified as 8, handle_device_event() copies 8 bytes into the destination variable instead of the desired 4, and overflows into the stack by 4 bytes. This patch fixes the corruption by adding an extra "out_length" argument to the send_request() function so that both in_length and out_length can be specified separately.

* [libraw1394 patch] Unify {ieee1394,fw}_bandwidth_modify()Gravatar Stefan Richter 2008-12-031-49/+0
| | | | | | | | | | | | because they do the same. We only may want a separate fw_bandwidth_modify() in the future when firewire-core gains a special ioctl() for that. (Not runtime-tested, but it looks good to me.) Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Dan Dennedy <dan@dennedy.org>
* [libraw1394 patch] Fix raw1394_channel_modify() on firewire-coreGravatar Stefan Richter 2008-12-031-49/+0
| | | | | | | | | | | | | | | | | | | (juju) Reported by Adrian Knoth: fw_channel_modify() was unable to allocate some channels which were actually free. http://marc.info/?l=linux1394-devel&t=122818128900002 This can be easily fixed by replacing fw_channel_modify() by ieee1394_channel_modify() because this is highlevel enough to work with Juju as well. We only may want a separate fw_channel_modify() in the future when firewire-core gains a special ioctl() for that. Also fix a documentation typo: raw1394_channel_modify() did not show up in extracted API documentation due to a cut'n'paste typo in raw1394.h.

* Fix segfault in juju's handle_arm_requestGravatar Stefan Richter 2008-10-281-0/+2
| | | | | | | The buffer pointers were uninitialized, leading to segfault in memcpy. Bug report and initial version of the fix by Adrian Knoth. Signed-off-by: Dan Dennedy <dan@dennedy.org>
* Makes extra sure strings are not overrun.Gravatar Erik Hovland 2008-10-281-13/+19
| | | | | | | | | When using strncpy with the exact size of the destination string the string may end up lacking null termination because the source string is bigger then the destination. Signed-off-by: Erik Hovland <erik@hovland.org> Signed-off-by: Dan Dennedy <dan@dennedy.org>
* Make sure that we have the right types.Gravatar Erik Hovland 2008-10-281-4/+4
| | | | | | | | When an unsigned type is assigned a signed value, the negatived value is never seen. Signed-off-by: Erik Hovland <erik@hovland.org> Signed-off-by: Dan Dennedy <dan@dennedy.org>
* Compare unsigned values instead of subtracting them.Gravatar Erik Hovland 2008-10-281-2/+3
| | | | | | | Unsigned values do not return signed values when subtracted and the right operand is larger then the left operand. Signed-off-by: Dan Dennedy <dan@dennedy.org>

* Plug dir leak and initialize data structsGravatar Philippe Troin 2008-07-051-1/+14
| | | | | | | | | | | | | | While trying to track down some crashes in kino, I found the following problems with libraw1394: * There is a DIR* leak in raw1394_set_port(). * Lots of data structures are not fully initialized when calling IEEE1394 ioctl()s. These cause valgrind errors (benign, as valgrind does not know how to interpret all ioctls. However these also cause kino to crash in libraw1394. I've added a bunch of memset()s to prevent this problem from happening. Forward-ported to libraw1394 git tree by Jarod Wilson.
* Move the source code files in the juju directory into the src directory andGravatar Dan Dennedy 2008-04-301-0/+1369
