bpo-35050: AF_ALG length check off-by-one error#10058
Merged

Conversation
The length check for AF_ALG salg_name and salg_type had a off-by-one error. The code assumed that both values are not necessarily NULL terminated. However the Kernel code for alg_bind() ensures that the last byte of both strings are NULL terminated. Signed-off-by: Christian Heimes <christian@python.org>
