From: Harry Morris <h.morris@xxxxxxxxxxx> v2 to catch length==1 packets or malformed packets read in ca8210_test_check_upstream() This patchset fixes a small bug in the ca8210 driver discovered by Domen Puncer Kugler <domen.puncer@xxxxxxxxxxx>. The bug allows for uninitialised memory to be sent out over SPI by writing unexpected commands to the debug interface. The bug is described in more detail in 1/1. This fix has been tested on a Raspberry Pi running kernel 4.9.37-v7+: harry@raspberrypi:~ $ sudo bash -c 'echo -ne "\x4f\x10" > /sys/kernel/debug/ca8210' bash: line 0: echo: write error: Invalid exchange harry@raspberrypi:~ $ Harry Morris (1): ieee802154: ca8210: fix uninitialised data read drivers/net/ieee802154/ca8210.c | 7 +++++++ 1 file changed, 7 insertions(+) -- 2.11.0 -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
