1 TODO list (most will be addressed in sudo 2.0)
3 01) Redo parsing to be more like op(8) with true command aliases where
4 can specify uid, gid(s) and part/all of the environment.
6 02) Add a SHELLS reserved word that checks against /etc/shells.
8 03) Make the sudoers file accessible via NIS, Hesiod, and maybe NetInfo.
10 04) Add a -h (?) flag to sudo for a history mechanism.
12 05) Add an option to set LD_LIBRARY_PATH?
14 06) Add Prog_Alias facility (Prog_Alias VI = /usr/secure/bin/vi +args).
16 07) check for <net/errno.h> in configure and include it in sudo.c if it exists.
18 08) Add generic STREAMS support for getting interfaces and netmasks.
20 09) Add support for "safe scripts" by checking for shell script
21 cookie (first two bytes are "#!") and execing the shell outselves
22 after doing the stat to guard against spoofing. This should avoid
23 the race condition caused by going through namei() twice...
25 10) Overhaul testsudoers to use things from parse.o so we don't reimplement
28 11) Make runas_user a struct "runas" with user and group components.
29 (maybe uid and gid too???)
31 12) Add -g group/gid option.
33 13) Should be able to mix Cmnd_Alias's and command args. Ie:
34 pete ALL=PASSWD [A-z]*,!PASSWD root
35 where PASSWD was defined to be /usr/bin/passwd.
36 This requires the arg parsing to happen in the yacc grammer.
37 At the very least, commands and args have to become separate
40 14) Add a per-tty restriction? Ie: only can run foo from /dev/console.
42 15) Add test for how to read ether interfaces in configure script
44 16) Add configure option to enable old behavior of visudo (O_EXCL)?
45 --without-sudoers-lock?
47 17) Profile sudo again (is the yacc grammar optimal?)
49 18) Zero out encrypted passwords after use. Use an Exit function or
50 some such (have to hook in to emalloc() and friends).
51 Hard (impossible?) to be thorough w/ atexit/on_exit.
53 19) Make 'sudo -l user' if run as root do a "sudo -l" output for the specified
56 20) Use strtol() and strtoul(), not atoi()
58 21) Look into %e, %p, %k in parse.lex
60 22) Make syslog stuff work on vanilla ultrix
62 23) Implement date_format and log_format options.
64 24) Add support for: Default:user@host
66 25) Make visudo rcs-aware
68 26) Add support for parsing multiple sudoers files. Basically make
69 _PATH_SUDOERS be a colon-separated list of pathname like EDITOR.
70 Requires _PATH_SUDOERS_TMP chages (perhaps "%s.tmp").
72 27) Some people want to be able to specify a special password in sudoers
73 in addition or instead of the normal one. The best argument for
74 this so far is to be able to use separate passwords for the
75 target users that are not the passwd file ones.
77 28) Add support for trusted users. E.g. allow user to run a certain
78 command regardless of what dir it is in if it is owned by the
81 28) Split the parser into two stages. The first parse checks for
82 syntax and sets the Defaults options and sets up the
83 data structures to check a user. The second stage does
84 the actual user check.
86 30) Add a flag similar to '-l' but that spits out sudo commands in
87 a format suitable for cut & paste (requires parser overhaul first).
89 31) Someone wants a recursive version of the dir specifier. Ie:
90 SOME_MODIFIER:/usr/local/ to allow anything under /usr/local to be run.
92 31) An option to set the shell to the target user would make sense.
93 See other target user-related issues above.
95 33) Add an option (-D) to dump the defaults after the sudoers file
96 has been parsed. Should only be available to root and should
97 allow a -u user modifier.
99 34) For sudo 1.7 wipe out the environment by default.
101 35) Allow /etc/sudoers to be a symlink but require the parent dir to
102 be root-owned and not writable by anything else. Should really
103 traverse the tree to the root doing this.
105 36) Improve interfaces.c STREAMS code (see ntpd's ntp_io.c for hints)
107 37) Wildcard support for user and group names? (netgroup too?)
109 38) If root_sudo is off, still allow sudo -u to non-root users?
111 39) Add configure option to id user based on euid not ruid?
113 40) Split $EDITOR/$VISUAL in visudo into an argument vector based on whitespace
115 41) Use proper links in .pod files
117 42) Parse gids like %#0
119 43) Add support for systrace (requires that sudo fork and be persistent)
121 44) For AIX, call getuserattr() to get resource limits and set them
123 http://nscp.upenn.edu/aix4.3html/libs/basetrf1/getuserattr.htm#A16691a89
125 45) Add an insult_path variable that is intialized to "builtin" but that
126 can point to other files containing an insult count as the first
127 line and that have a constant record length (sparse files) for
130 46) Investigate using glob(3) instead of fnmatch(3) for path matching. That
131 way we can stat each potential match like we normally would. Patterns
132 ending in '/*' can be replaced with '/basename' as an optimization.
134 47) Some way of using a new pty for the program run via sudo would prevent
135 access to the caller's /dev/tty (but probably makes job control tricky).
137 48) Maybe have a database of checksums that commands are verified against.
138 Basically replace the st_ino/st_dev check with a checksum lookup.
140 49) Look into testing writability of a file via sudoedit *before* doing
141 the edit; e.g., try opening with O_APPEND.
143 50) Add Makefile.in bits to autogenerate Solaris and HP-UX packages
