From: Jouni Malinen Date: Wed, 2 Nov 2011 21:45:55 +0000 (+0200) Subject: ath6kl: Fix key configuration to copy at most seq_len from seq X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f4bb9a6fbc1f49058fc9eb6dcb4a3022d99013b4;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ath6kl: Fix key configuration to copy at most seq_len from seq There is no guarantee on the caller using 8-octet buffer for key->seq, so better follow the key->seq_len parameter on figuring out how many octets to copy.
