commit f9c52831133050c6b82aa8b6831c92da2bbf2a0b upstream.

This patch is necessary if case of AF_PACKET or other socket interface

mac802154: tx: use put_unaligned_le16 for copy crc

2018-12-16T22:08:36+00:00

commit 061ef8f915988839b12460c47ebfcf3700e124f0 upstream.

This patch replaces the memcpy with a put_unaligned_le16. The placement
of crc inside of PSDU can also be unaligned. With memcpy this can fail
on some architectures.

mac802154: don't deliver packets to devices that are down

2014-06-11T19:10:19+00:00

Only one WPAN devices can be active at any given time, so only deliver
packets to that one interface that is actually up. Multiple monitors may
be up at any given time, but we don't have to deliver to monitors that
are down either.

mac802154: properly free incoming skbs on decryption failure

2014-06-11T19:10:18+00:00

mac802154 RX did not free skbs on decryption failure, assuming that the
caller would when the local rx handler returned _DROP. This was false.

mac802154: llsec: add forgotten list_del_rcu in key removal

2014-06-06T23:25:37+00:00

During key removal, the key object is freed, but not taken out of the
llsec key list properly. Fix that.

Key id comparison for type 1 keys (implicit source, with index) should
return true if mode and id are equal, not false.

mac802154: llsec: fold useless return value check

2014-05-22T19:24:13+00:00

llsec_do_encrypt will never return a positive value, so the restriction
to 0-or-negative on return is useless.

mac802154: llsec: fix incorrect lock pairing

2014-05-22T19:24:13+00:00

In encrypt, sec->lock is taken with read_lock_bh, so in the error path,
we must read_unlock_bh.
