mainline inclusion from mainline-master commit 2d016672528a592ada5188e53ac746e1b8b7a978 category: bugfix bugzilla: 173981 CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Actual data length of the 'secret' is not equal to the 'secret_size'.
Since the 'curve_id' has removed in the 'secret', the 'secret_size' should subtract the length of the 'curve_id'.
