v0.50.2

Changes

• e574068: fixed #460 - do not panic on mlock failures (#464) (Eugene) #464

Reverted a change from 0.50.0 that made cryptovec panic when the OS fails to mlock() the memory.

Instead, russh-cryptovec will log a one-time log warning about this.

A common cause for these errors is running on Linux under a low RLIMIT_MEMLOCK limit

Docs
