crypto: af_alg - Fix incorrect boolean values in af_alg_ctx
In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Fix incorrect boolean values in af_alg_ctx
Commit 1b34cbbf4f01 ("crypto: af_alg - Disallow concurrent writes in
af_alg_sendmsg") changed some fields from bool to 1-bit bitfields of
type u32.
However, some assignments to these fields, specifically 'more' and
'merge', assign values greater than 1. These relied on C's implicit
conversion to bool, such that zero becomes false and nonzero becomes
true.
With a 1-bit bitfields of type u32 instead, mod 2 of the value is taken
instead, resulting in 0 being assigned in some cases when 1 was intended.
Fix this by restoring the bool type.
