tor/changes/bug31570

  o Major bugfixes (crash, android):
    - Tolerate systems (including some Android installations) where madvise
      and MADV_DONTDUMP are available at build-time, but not at run time.
      Previously, these systems would notice a failed syscall and abort.
      Fixes bug 31570; bugfix on 0.4.1.1-alpha.
madvise: tolerate EINVAL and ENOSYS 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 31570. I am calling this a bugfix on 0.4.1.1-alpha, where we actually started using the map_anon code. 2019-09-02 20:49:53 +02:00			`o Major bugfixes (crash, android):`
