Subject: [SCTP]: Correctly set the length of sctp_assoc_change notification
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b90a137d30a6322d76023d879d40fc31f3edf0a6;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[SCTP]: Correctly set the length of sctp_assoc_change notification

sctp_assoc_change notification may contain the data from a received
ABORT chunk.  Set the length correctly to account for that.
