Subject: [PATCH] kcapi: Fix hang in fuzz tests with recent kernels
|
|
|
|
After kernel commit f3c802a1f300 ("crypto: algif_aead - Only wake up
|
|
when..."), the fuzz tests hang indefinitely, because they request more
|
|
output data than the operation can produce. Fix this by requesting at
|
|
most the expected size of the output data.
