1TODO list (most will be addressed in sudo 2.0) 2 301) 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. 5 602) Add a SHELLS reserved word that checks against /etc/shells. 7 803) Make the sudoers file accessible via NIS, Hesiod, and maybe NetInfo. 9 1004) Add a -h (?) flag to sudo for a history mechanism. 11 1205) Add an option to set LD_LIBRARY_PATH? 13 1406) Add Prog_Alias facility (Prog_Alias VI = /usr/secure/bin/vi +args). 15 1607) check for <net/errno.h> in configure and include it in sudo.c if it exists. 17 1808) Add generic STREAMS support for getting interfaces and netmasks. 19 2009) 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... 24 2510) Overhaul testsudoers to use things from parse.o so we don't reimplement 26 things. 27 2811) Make runas_user a struct "runas" with user and group components. 29 (maybe uid and gid too???) 30 3112) Add -g group/gid option. 32 3313) 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 38 tokens in the lexer. 39 4014) Add a per-tty restriction? Ie: only can run foo from /dev/console. 41 4215) Add test for how to read ether interfaces in configure script 43 4416) Add configure option to enable old behavior of visudo (O_EXCL)? 45 --without-sudoers-lock? 46 4717) Profile sudo again (is the yacc grammar optimal?) 48 4918) 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. 52 5319) Make 'sudo -l user' if run as root do a "sudo -l" output for the specified 54 user. 55 5620) Use strtol() and strtoul(), not atoi() 57 5821) Look into %e, %p, %k in parse.lex 59 6022) Make syslog stuff work on vanilla ultrix 61 6223) Implement date_format and log_format options. 63 6424) Add support for: Default:user@host 65 6625) Make visudo rcs-aware 67 6826) 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"). 71 7227) 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. 76 7728) 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 79 trusted user. 80 8128) 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. 85 8630) Add a flag similar to '-l' but that spits out sudo commands in 87 a format suitable for cut & paste (requires parser overhaul first). 88 8931) Someone wants a recursive version of the dir specifier. Ie: 90 SOME_MODIFIER:/usr/local/ to allow anything under /usr/local to be run. 91 9231) An option to set the shell to the target user would make sense. 93 See other target user-related issues above. 94 9533) 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. 98 9934) For sudo 1.7 wipe out the environment by default. 100 10135) 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. 104 10536) Improve interfaces.c STREAMS code (see ntpd's ntp_io.c for hints) 106 10737) Wildcard support for user and group names? (netgroup too?) 108 10938) If root_sudo is off, still allow sudo -u to non-root users? 110 11139) Add configure option to id user based on euid not ruid? 112 11340) Split $EDITOR/$VISUAL in visudo into an argument vector based on whitespace 114 11541) Use proper links in .pod files 116 11742) Parse gids like %#0 118 11943) Add support for systrace (requires that sudo fork and be persistent) 120 12144) For AIX, call getuserattr() to get resource limits and set them 122 as appropriate, see: 123 http://nscp.upenn.edu/aix4.3html/libs/basetrf1/getuserattr.htm#A16691a89 124 12545) 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 128 easy seeking. 129 13046) 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. 133 13447) 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). 136 13748) Maybe have a database of checksums that commands are verified against. 138 Basically replace the st_ino/st_dev check with a checksum lookup. 139 14049) Look into testing writability of a file via sudoedit *before* doing 141 the edit; e.g., try opening with O_APPEND. 142 14350) Add Makefile.in bits to autogenerate Solaris and HP-UX packages 144
