Jukka Rissanen 9ea5140565 6lowpan: Uncompression of traffic class field was incorrect ... [ Upstream commit 1188f05497 ] If priority/traffic class field in IPv6 header is set (seen when using ssh), the uncompression sets the TC and Flow fields incorrectly. Example: This is IPv6 header of a sent packet. Note the priority/TC (=1) in the first byte. 00000000: 61 00 00 00 00 2c 06 40 fe 80 00 00 00 00 00 00 00000010: 02 02 72 ff fe c6 42 10 fe 80 00 00 00 00 00 00 00000020: 02 1e ab ff fe 4c 52 57 This gets compressed like this in the sending side 00000000: 72 31 04 06 02 1e ab ff fe 4c 52 57 ec c2 00 16 00000010: aa 2d fe 92 86 4e be c6 .... In the receiving end, the packet gets uncompressed to this IPv6 header 00000000: 60 06 06 02 00 2a 1e 40 fe 80 00 00 00 00 00 00 00000010: 02 02 72 ff fe c6 42 10 fe 80 00 00 00 00 00 00 00000020: ab ff fe 4c 52 57 ec c2 First four bytes are set incorrectly and we have also lost two bytes from destination address. The fix is to switch the case values in switch statement when checking the TC field. Signed-off-by: Jukka Rissanen <jukka.rissanen@linux.intel.com> Signed-off-by: David S.
