  o Minor bugfixes (sandbox):

    - Handle failures in getpwnam()/getpwuid() when running with the
      User option set and the Linux syscall sandbox enabled. Fixes bug
      11946; bugfix on 0.2.5.1-alpha.
Use tor_getpw{nam,uid} wrappers to fix bug 11946 When running with User set, we frequently try to look up our information in the user database (e.g., /etc/passwd). The seccomp2 sandbox setup doesn't let us open /etc/passwd, and probably shouldn't. To fix this, we have a pair of wrappers for getpwnam and getpwuid. When a real call to getpwnam or getpwuid fails, they fall back to a cached value, if the uid/gid matches. (Granting access to /etc/passwd isn't possible with the way we handle opening files through the sandbox. It's not desirable either.) 2014-05-14 19:53:14 +02:00			`o Minor bugfixes (sandbox):`
