  • Committer: Teddy Hogeborn
  • Date: 2008-09-26 04:54:35 UTC
  • Revision ID: teddy@fukt.bsnet.se-20080926045435-0thnnqops1kzclag
* debian/mandos-client.postinst: Change home directory to
                                 "/nonexistent".
* debian/mandos.postinst: - '' -

* plugin-runner.c (main): Bug fix: Block signals while modifying
                          "plugin_list".

* plugins.d/usplash.c (usplash_write): New function.
  (main): Use "usplash_write" to write "INPUTQUIET" command.  Also
          write "TIMEOUT 0" before it, and write "TIMEOUT 15" and
          "PULSATE" if starting a new usplash process.  Kill old
          usplash before forking.  Bug fix: do setuid(geteuid()) to
          preserve genuine rootness.  Better interrupted/error logic
          overall.

* debian/mandos-client.lintian-overrides: Ignore setuid
                                          "plugins.d/usplash".
