Subject: [ima-evm-utils PATCH 2/5] Set size of xattr_value to MAX_SIGNATURE_SIZE
Date: Sun, 5 Apr 2026 20:08:07 -0400 [thread overview]
Message-ID: <20260406000810.4013201-3-stefanb@linux.ibm.com> (raw)
In-Reply-To: <20260406000810.4013201-1-stefanb@linux.ibm.com>
Set the size of an xattr_value that can be read to MAX_SIGNATURE_SIZE
so that ML-DSA keys can also be read once enabled (and MAX_SIGNATURE_SIZE
gets a larger value).
