OpenSSL BIO classes provide an abstraction for dealing with I/O. OpenSSL provides BIO classes for commonly used I/O primitives backed by file descriptors, sockets, etc. as well as permitting consumers of OpenSSL to define custom BIO classes. One of the methods BIO classes implement is a control method invoked by BIO_ctrl() for various ancilliary tasks somewhat analgous to fcntl() and ioctl() on file descriptors. According to the BIO_ctrl(3) manual page, control methods should return 0 for unknown control requests. KTLS support in OpenSSL adds new control requests. Two of those new requests are queries to determine if KTLS is enabled for either reading or writing. These control reuquest return 1 if KTLS is enabled and 0 if it is not. serf includes two custom BIO classes for wrapping I/O requests from files and from a buffer in memory. These BIO classes both use a custom control method. However, this custom control method was returning 1 for unknown or unsupported control requests instead of 0. As a result, OpenSSL with KTLS believed that these BIOs were using KTLS and were thus adding headers and doing encryption/decryption in the BIO. Correcting the return value removes this confusion.

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
