mscan: too much data copied to CAN frame due to 16 bit accesses

2011-10-10T18:31:00Z

Due to the 16 bit access to mscan registers there's too much data copied to the zero initialized CAN frame when having an odd number of bytes to copy. This patch ensures that only the requested bytes are copied by using an 8 bit access for the remaining byte.

drivers/net/can/sja1000/plx_pci.c: eliminate double free

2011-08-14T01:00:32Z

In this code, the failure_cleanup label calls the function plx_pci_del_card, which frees everything in the card->net_dev array. dev is placed in this array immediately after allocation, so the two subsequent jumps to failure_cleanup should not also call free_sja1000dev, but the second one does. If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on dev. Because dev is already in the card->net_dev array, this implies that when plx_pci_del_card is later called, it may get freed again. So that entry is reset to NULL after the free. Finally, if there is a problem with one channel, there will be a hole in the array. card->channels counts the number of channels that have succeeded, and does not keep track of the index of the largest element in the array that is valid. So the loop in plx_pci_del_card is changed to go up to PLX_PCI_MAX_CHAN, which is only 2. Signed-off-by: Julia Lawall Signed-off-by: David S. Miller

slcan: ldisc generated skbs are received in softirq context

2011-08-11T12:52:57Z

As this discussion pointed out http://marc.info/?l=linux-netdev&m=131257225602375 netdevices that are based on serial line disciplines should use netif_rx_ni() when pushing received socketbuffers into the netdev rx queue. Following commit 614851601c121b1320a35757ab88292d6272f906 ("slip: fix NOHZ local_softirq_pending 08 warning") this patch updates the slcan driver accordingly.
