4.2.0 - 2020-03-17

Added

• New API function slirp_add_unix: add a forward rule to a Unix socket.
• New API function slirp_remove_guestfwd: remove a forward rule previously added by slirp_add_exec, slirp_add_unix or slirp_add_guestfwd
• New SlirpConfig.outbound_addr{,6} fields to bind output socket to a specific address

Changed

• socket: do not fallback on host loopback if get_dns_addr() failed or the address is in slirp network

Fixed

• ncsi: fix checksum OOB memory access
• tcp_emu(): fix OOB accesses
• tftp: restrict relative path access
• state: fix loading of guestfwd state

4.1.0 - 2019-12-02

Added

• The slirp_new() API, simpler and more extensible than slirp_init().
• Allow custom MTU configuration.
• Option to disable host loopback connections.
• CI now runs scan-build too.

Changed

• Disable tcp_emu() by default. tcp_emu() is known to have caused several CVEs, and not useful today in most cases. The feature can be still enabled by setting SlirpConfig.enable_emu to true.
• meson build system is now subproject() friendly.
• Replace remaining malloc()/free() with glib (which aborts on OOM)
• Various code cleanups.

Deprecated

• The slirp_init() API.

Fixed

• getpeername() error after shutdown(SHUT_WR).
• Exec forward: correctly parse command lines that contain spaces.
• Allow 0.0.0.0 destination address.
• Make host receive broadcast packets.
• Various memory related fixes (heap overflow, leaks, NULL dereference).
• Compilation warnings, dead code.

4.0.0 - 2019-05-24

Added

• Installable as a shared library.
• meson build system (& make build system for in-tree QEMU integration)

Changed

• Standalone project, removing any QEMU dependency.
• License clarifications.
