2022-07-25macsec: limit replay window size with XPNSabrina Dubroca
IEEE 802.1AEbw-2013 (section 10.7.8) specifies that the maximum value of the replay window is 2^30-1, to help with recovery of the upper bits of the PN. To avoid leaving the existing macsec device in an inconsistent state if this test fails during changelink, reuse the cleanup mechanism introduced for HW offload. This wasn't needed until now because macsec_changelink_common could not fail during changelink, as modifying the cipher suite was not allowed. Finally, this must happen after handling IFLA_MACSEC_CIPHER_SUITE so that secy->xpn is set.

2022-07-25macsec: fix NULL deref in macsec_add_rxsaSabrina Dubroca
Commit 48ef50fa866a added a test on tb_sa[MACSEC_SA_ATTR_PN], but nothing guarantees that it's not NULL at this point. The same code was added to macsec_add_txsa, but there it's not a problem because validate_add_txsa checks that the MACSEC_SA_ATTR_PN attribute is present. Note: it's not possible to reproduce with iproute, because iproute doesn't allow creating an SA without specifying the PN.

An MAE port, or m-port, is a port (source/destination for traffic) on the Match-Action Engine (the internal switch on EF100). Representors will use their representee's m-port for two purposes: as a destination override on TX from the representor, and as a source match in 'default rules' to steer representee traffic (when not matched by e.g. a TC flower rule) to representor RX via the parent PF's receive queue.
