| | | | | Some object file diffs, but they are harmless. (Mostly they seem to come from internal counters in gcc... and in one case the order of two instructions was harmlessly swapped, which is odd and annoying.)

* Security improvements for games (largely from or inspired by OpenBSD).jsm1999-09-121-1/+4
| | | | | | | | | | | | | | | Games which run setgid from dm, but don't need to, should drop their privileges at startup. Games which have a scorefile should open it at startup, then drop all privileges leaving just the open writable file descriptor. If the game can invoke subprocesses, this should be made close-on-exec. Games with scorefiles should make sure they do not get a file descriptor < 3. (Otherwise, they could get confused and corrupt the scorefile when using stdin, stdout or stderr.) Some old setuid revokes from the days of setuid games change into gid revokes.
* Add use of `const' where appropriate to the games.jsm1999-09-081-7/+7

Some such changes were previously covered in PRs bin/6041, bin/6146, bin/6148, bin/6150, bin/6151, bin/6580, bin/6660, bin/7993, bin/7994, bin/8039, bin/8057 and bin/8093.
