As was pointed out in the bug: https://bugs.archlinux.org/task/65517#comment186483 ssh errors with: kex_exchange_identification: read: Connection reset by peer sshd logs the error: fatal: recv_rexec_state: buffer error: incomplete message It's pretty plausible that this commit is simply incompatible with the previous version of sshd, therefore it could not reexec: https://github.com/openssh/openssh-portable/commit/c2bd7f74b0e0f3a3ee9d19ac549e6ba89013abaf So this is "expected" behavior. There's no way to upgrade this without triggering the need for a restart. All consumers of openssh on any operating system will need to restart sshd, possibly via maintenance scripts provided by the distro. -- Eli Schwartz Bug Wrangler and Trusted User
