Source: linux Version: 5.10.28-1 Severity: wishlist The current configuration does not enable the multipath TCP functionality provided by the kernel through the MPTCP (and the the-default MPTCP_IPV6) binary options. These have been available since kernel version 5.6. When enabled, user space applications can opt in to MPTCP behavior by using the new IPPROTO_MPTCP; regular TCP connections are unaffected. Applications using this are starting slowly (outside of the Apple ecosystem where this has been in used for years to ensure smooth network handovers), but having this available widely would make it easier for application developers to verify MPTCP operation on systems where they can't easily (or don't have the experience to) rebuild their kernel with CONFIG_MPTCP=y. Please consider enabling this feature. -- System Information: Debian Release: 11.0 APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.12.0-rc5 (SMP w/8 CPU threads) Kernel taint flags: TAINT_WARN, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled -- To use raw power is to make yourself infinitely vulnerable to greater powers. -- Bene Gesserit axiom
