can: peak_usb: fix cleanup sequence order in case of error during init

2015-04-14T09:33:45Z

commit af35d0f1cce7a990286e2b94c260a2c2d2a0e4b0 upstream. This patch sets the correct reverse sequence order to the instructions set to run, when any failure occurs during the initialization steps. It also adds the missing unregistration call of the can device if the failure appears after having been registered.

can: peak_usb: fix memset() usage

2015-04-14T09:33:45Z

commit dc50ddcd4c58a5a0226038307d6ef884bec9f8c2 upstream. This patchs fixes a misplaced call to memset() that fills the request buffer with 0. The problem was with sending PCAN_USBPRO_REQ_FCT requests, the content set by the caller was thus lost. With this patch, the memory area is zeroed only when requesting info from the device.

can: esd_usb2: fix memory leak on disconnect

2015-02-02T09:05:22Z

commit efbd50d2f62fc1f69a3dcd153e63ba28cc8eb27f upstream. It seems struct esd_usb2 dev is not deallocated on disconnect. The patch adds the missing deallocation.

can: pcan_usb: fix wrong memcpy() bytes length

2013-08-20T15:26:28Z

commit 3c322a56b01695df15c70bfdc2d02e0ccd80654e upstream. Fix possibly wrong memcpy() bytes length since some CAN records received from PCAN-USB could define a DLC field in range [9..15]. In that case, the real DLC value MUST be used to move forward the record pointer but, only 8 bytes max. MUST be copied into the data field of the struct can_frame object of the skb given to the network core. Signed-off-by: Stephane Grosjean Signed-off-by: Marc Kleine-Budde Signed-off-by: David S.

can: peak_usb: fix hwtstamp assignment

2012-12-03T19:47:09Z

commit c9faaa09e2a1335678f09c70a0d0eda095564bab upstream. The skb->tstamp is set to the hardware timestamp when available in the USB urb message. This leads to user visible timestamps which contain the 'uptime' of the USB adapter - and not the usual system generated timestamp. Fix this wrong assignment by applying the available hardware timestamp to the skb_shared_hwtstamps data structure - which is intended for this purpose.

can: usb: PCAN-USB Pro: fix mem leaks in pcan_usb_pro_init() on error paths

2012-04-16T19:34:50Z

If either call to pcan_usb_pro_send_req() in drivers/net/can/usb/peak_usb/pcan_usb_pro.c::pcan_usb_pro_init() fails, we'll leak the memory we allocated to 'usb_if' with kzalloc() when the 'usb_if' variable goes out of scope without having been assigned to anything as we 'return err;'. Fix this by adding appropriate kfree(usb_if) calls to the error paths. Signed-off-by: Jesper Juhl Acked-by: Stephane Grosjean Signed-off-by: Marc Kleine-Budde

can: peak_usb: PCAN-USB specific part: fix little endian usage

2012-03-07T14:51:01Z

That patch fixes some bad usage of two little-endian variables, which lead to some warning/error when building the peak_usb driver. Reported-by: Dan Carpenter Acked-by: Marc Kleine-Budde Signed-off-by: Stephane Grosjean Signed-off-by: Marc Kleine-Budde
