- ---------------------------------------------------------------------

* Thu Apr 14 2005 Jason Vas Dias - 4.1-33_FC3

- - fix bug 154922 / CAN-2005-1038: check that new crontab is
regular file after editor session ends.
- - fix bug 154575: use PATH_MAX (4096) as max filename length; also make
limits on command line and env.var. lengths sensible (131072).

* Fri Apr 8 2005 Jason Vas Dias - 4.1-33_FC3

- - do pam_close_session and pam_setcred(pamh, PAM_DELETE_CRED)
- - if fork fails

* Thu Apr 7 2005 Jason Vas Dias - 4.1-33_FC3

- - fix bug 154065: crontab's job control broken: by
- - xpid = waitpid(pid,&waiter,WUNTRACED);...
- - if( WIFSTOPPED(waiter) )... kill(getpid(),WSTOPSIG(waiter));
- - crontab should not kill itself with SIGSTOP if its child
- - gets SIGSTOP; hence it does not need the waitpid WUNTRACED flag.

* Tue Apr 5 2005 Jason Vas Dias - 4.1-33_FC3

- - Required for EAL Audit certification:
- - If pam_setcred should fail, the pam_session could fail to be
- - closed, leaving autofs user directories still mounted.

* Tue Mar 15 2005 Jason Vas Dias - 4.1-33_FC3

- - fix bug 151145: segfault if cronjob runs without any SELinux user
- - security context (eg. in a broken chroot environment)

* Fri Feb 25 2005 Jason Vas Dias - 4.1-24_FC3

- - Fix bug 147636 - disable silly mail recipient name checking
- - (do_command.c's safe_p()) by default . Can be enabled by

- - environment - also '_'s in MAILTOs are allowed.

* Tue Jan 25 2005 Jason Vas Dias - 4.1-21_FC3

* Thu Sep 30 2004 Jason Vas Dias - 4.1-17
