o stay_setuid - sudo will remain setuid if system has saved uids or setreuid(2)
o env_reset - reset the environment to a sane default
o env_keep - preserve environment variables that would otherwise be cleared
No longer use getenv/putenv/setenv functions--do environment munging by hand.
Potentially dangerous environment variables can be cleared only if they
contain '/' pr '%' characters to protect buggy programs.
Moved environment routines into env.c (new file)
o Implement mailer_flags
o Store syslog stuff both in int and string form. Setting the string
form magically updates the int version.
o Add boolean attribute to strings where it makes sense to say !foo
changable at runtime (and on a global, per-host and per-user basis).
Both the names and the internal representation are still subject to change.
It was necessary to make sudo_user.runas but a char ** instead of a
char * since this value can be changed by a Defaults line. There is a
similar (but more complicated) issue with sudo_user.prompt but it
is handled differently at the moment.
Add a "-L" flag to list the name of options with their descriptions. This
may only be temporary.
Move some prototypes to parse.h
Be much less restrictive on what is allowed for a username.
possible to express things like "failed to validate because user not listed
for this host". Some thigns that were previously VALIDATE_FOO are now
FLAG_FOO. This may change later on.
Reorganized code in log_auth() and sudo.c to deal with above changes.
Safer versions of push/pushcp with in the do { ... } while (0) style
parse.yacc now saves info on the stack to allow parse.c to determine
if a user was listed, but not for the host he/she tried to run on.
Added --with-mail-if-no-host option
o real dependencies in the Makefile
o --with-devel option to enable yacc, lex, and -Wall
o style -- "foo -> bar" becomes "foo->bar"
o ALL goes back to being a token, not a string but don't leak memory
o rename hsotspec -> host in parse.yacc
where an alias may be used before it is defined. Only turned on for visudo
and testsudoers.
o Add --disable-authentication option that makes sudo not require
authentication by default. The PASSWD tag can be used to require
authentication for an entry. We no longer overload --without-passwd.
o Visudo now locks the sudoers temp file instead of bailing when
the temp file already exists. This fixes the problem of stale
temp files but it does *require* that you not try to put the
temp file in a world-writable directory. This shoud not be
an issue as the temp file should live in the same dir as sudoers.
o Visudo now only installs the temp file as sudoers if it changed.
system strdup(3) which may or may not exist. There is now no need to
provide strdup() for those w/o it. Also, the prototype for estrdup()
was wrong, it returns char * and its param is const.
