Subject: af_key: fix SADB_X_SPDDELETE response
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1839faab9a2747bcd30ee14e50575a39bf6735d4;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

af_key: fix SADB_X_SPDDELETE response

When deleting an SPD entry using SADB_X_SPDDELETE, c.data.byid is not
initialized to zero in pfkey_spddelete(). Thus, key_notify_policy()
responds with a PF_KEY message of type SADB_X_SPDDELETE2 instead of
SADB_X_SPDDELETE.
