powerpc64 switched to ELFv2 ABI at the same time it switched to LLVM. This brings us to a parity with modern Linux distributions. This also makes the binaries from previous FreeBSD versions incompatible with 13.0-RELEASE.
Kernel Changes
The GENERIC kernels for amd64 and i386 now include aesni(4) to support accelerated software cryptography for geli(8) by default.
The GENERIC kernel for aarch64 now includes armv8crypto(4) to support accelerated software cryptography for geli(8) by default. Now aarch64 supports AES-XTS and AES-GCM.
Added Safe Memory Reclamation (SMR) to the kernel, a light weight variant of epoch reclamation closely coupled to uma(9). This has been applied in parts of the VM subsystem and VFS layer to improve scalability on high core count systems.
The suite of VirtIO device drivers now support the VirtIO V1 spec. This improves FreeBSD’s compatibility as a guest operating system with various hypervisors and emulators including the ability to run on the Q35 chipset under QEMU.
For iscsi(4) and ctld(8), support for specifying network QoS in the form of DiffServ Codepoints (DSCP) and Ethernet Priority Code Point (PCP) was added.
The kernel now provides a default implementation for the SEEK_DATA and SEEK_HOLE ioctl(2)’s for filesystems which do not support sparse files.
The NFS client and server now support NFS over TLS. The additional userland daemons are not built by default but can be enabled by building a new world that includes a KTLS-enabled OpenSSL via the WITH_OPENSSL_KTLS option.
A new nfsv4_server_only variable can be set to YES in /etc/rc.conf to only enable support for NFSv4. This avoids the need to run rpcbind(8) on an NFS server.
The NFS client and server now support NFSv4.2 (RFC 7862) and Extended Attributes (RFC 8276).
The ZFS implementation is now provided by OpenZFS.
Updated the fusefs(5) protocol to 7.28 along with adding support for FUSE_COPY_FILE_RANGE and FUSE_LSEEK.
The kernel now supports in-kernel framing and encryption of Transport Layer Security (TLS) data on TCP sockets for TLS versions 1.0 through 1.3. Transmit offload via in-kernel crypto drivers is supported for MtE cipher suites using AES-CBC as well as AEAD cipher suites using AES-GCM. Receive offload via in-kernel crypto drivers is supported for AES-GCM cipher suites for TLS 1.2. Using KTLS requires the use of a KTLS-aware userland SSL library. The OpenSSL library included in the base system does not enable KTLS support by default, but support can be enabled by building with the WITH_OPENSSL_KTLS option.
tcp(4) now supports Proportional Rate Reduction (as described by RFC6937) to improve SACK loss recovery during burst loss and ACK thinning scenarios. This feature is enabled by default.
The amd64 architecture now supports 57-bit virtual addresses (LA57) on supported CPUs. This permits user processes to use up to** 56 bits of virtual address space**. This also includes support for five layer nested page tables used by bhyve.
The 64-bit ARM architecture known as arm64 or AArch64 is promoted to Tier-1 status for FreeBSD 13.
All powerpc architectures switched to LLVM and are currently mostly similar to amd64 toolchain-wise.
powerpc64le (64-bit little endian port) was introduced, targeting POWER8 and newer processors.
The bhyve(8) utility now supports VirtIO-9p (aka VirtFS) filesystem sharing.
