tor/changes/bug31696

  o Major bugfixes (crash, Linux):
    - Tolerate systems (including some Linux installations) where madvise
      and/or MADV_DONTFORK are available at build-time, but not at run time.
      Previously, these systems would notice a failed syscall and abort.
      Fixes bug 31696; bugfix on 0.4.1.1-alpha.
madvise: tolerate EINVAL and ENOSYS when minherit fails These errors can occur if we are built on a system with support for madvise(MADV_NOFORK) but then we are run on a system whose kernel does not support that flag. If the error is something that we don't tolerate at all, we now log it before crashing. Fixes bug 31696. I am calling this a bugfix on 0.4.1.1-alpha, where we actually started using the map_anon code. This is similar to, but not the same as, the fix for #31570. 2019-09-11 15:13:50 +02:00			`o Major bugfixes (crash, Linux):`
