Subject: [PATCH 12/16] crypto/dpaa2_sec: fix bitmask truncation
Date: Thu, 14 Nov 2024 22:05:49 -0800 [thread overview]
Message-ID: <20241115060738.313190-13-stephen@networkplumber.org> (raw)
In-Reply-To: <20241115060738.313190-1-stephen@networkplumber.org>
The dqrr_held mask is 64 bit but updates were getting truncated
because 1 is of type int (32 bit) and the result shift of int is of
type int (32 bit); therefore any value >= 32 would get truncated.
