TODO list (most will be addressed in sudo 2.0) 01) Redo parsing to be more like op(8) with true command aliases where can specify uid, gid(s) and part/all of the environment. 02) Add a SHELLS reserved word that checks against /etc/shells. 03) Make the sudoers file accessible via NIS, Hesiod, and maybe NetInfo. 04) Add a -h (?) flag to sudo for a history mechanism. 05) Add an option to set LD_LIBRARY_PATH? 06) Add Prog_Alias facility (Prog_Alias VI = /usr/secure/bin/vi +args). 07) check for in configure and include it in sudo.c if it exists. 08) Add generic STREAMS support for getting interfaces and netmasks. 09) Add support for "safe scripts" by checking for shell script cookie (first two bytes are "#!") and execing the shell outselves after doing the stat to guard against spoofing. This should avoid the race condition caused by going through namei() twice... 10) Overhaul testsudoers to use things from parse.o so we don't reimplement things. 11) Make runas_user a struct "runas" with user and group components. (maybe uid and gid too???) 12) Add -g group/gid option. 13) Should be able to mix Cmnd_Alias's and command args. Ie: pete ALL=PASSWD [A-z]*,!PASSWD root where PASSWD was defined to be /usr/bin/passwd. This requires the arg parsing to happen in the yacc grammer. At the very least, commands and args have to become separate tokens in the lexer. 14) Add a per-tty restriction? Ie: only can run foo from /dev/console. 15) Add test for how to read ether interfaces in configure script 16) Add configure check for $(CC) -R and use it in addition to -L 17) An option to make "sudo -s" use the target user's shell might be nice (and more like su). Overlaps with the upcoming -i option. 18) Add configure option to enable old behavior of visudo (O_EXCL)? --without-sudoers-lock? 19) Profile sudo again (is the yacc grammar optimal?) 20) Zero out encrypted passwords after use. Use an Exit function or some such (have to hook in to emalloc() and friends). Hard (impossible?) to be thorough w/ atexit/on_exit. 21) Make 'sudo -l user' if run as root do a "sudo -l" output for the specified user. 22) Use strtol() and strtoul(), not atoi() 23) In parse.yacc get rid of unneeded '{ ; }' 24) Look into %e, %p, %k in parse.lex 25) Make syslog stuff work on vanilla ultrix 26) Implement date_format and log_format options. 27) Add support for: Default:user@host 28) Do login-style -sh hack for sudo -s? (new option or do it always?) 29) Make visudo rcs-aware 30) Add support for parsing multiple sudoers files. Basically make _PATH_SUDOERS be a colon-separated list of pathname like EDITOR. Requires _PATH_SUDOERS_TMP chages (perhaps "%s.tmp"). 31) Add -i (simulate initial login) option as per 946 +sudo (requires two-pass parser). Also add "default_path" Defaults option to go with it. (See MINUS_I.patch) 32) Some people want to be able to specify a special password in sudoers in addition or instead of the normal one. The best argument for this so far is to be able to use separate passwords for the target users that are not the passwd file ones. 33) Add support for trusted users. E.g. allow user to run a certain command regardless of what dir it is in if it is owned by the trusted user. 34) Add mechanism to choose logfile based on RunasUser 35) Split the parser into two stages. The first parse checks for syntax and sets the Defaults options and sets up the data structures to check a user. The second stage does the actual user check. 36) Add a flag similar to '-l' but that spits out sudo commands in a format suitable for cut & paste (requires parser overhaul first). 37) Someone wants a recursive version of the dir specifier. Ie: SOME_MODIFIER:/usr/local/ to allow anything under /usr/local to be run. 38) An option to set the shell to the target user would make sense. See other target user-related issues above. 39) Add an option (-D) to dump the defaults after the sudoers file has been parsed. Should only be available to root and should allow a -u user modifier. 40) For sudo 1.7 wipe out the environment by default.
