7a07ad8641 Don't look at prev_user until after we've parsed sudoers and done the 
password check.  That way, if sudo/sudoedit is run from a root process
that was invoked by sudo, we check sudoers for root, not the previous
user.  This makes sudoedit much more useful and means that for the
sudo case, we get correct logging on who actually ran the command.

5a972df0ba noexec now replaces more than just execve() 2004-01-22 19:18:50 +00:00
Todd C. Miller
4ad4ba1740 Alas, all the world does not go through execve(2). Many systems 
still have an execv(2) system call, Linux 2.6 provides fexecve(2)
and it is not uncommon for libc to have underscore ('_') versions
of the functions to be used internally by the library.  Instead of
stubbing all these out by hand, define a macro and let it do the
work.  Extra exec functions pointed out by Reznic Valery.

5ccddf8176 Fix suspending the editor in -e mode. Because we do a fork() first 
we need to be notified when the child has been stopped and then send
that same signal to ourself so the shell can do its job control thing.

24155a405a Use WIFEXITED and WEXITSTATUS macros. If there are systems out there 
that want to run sudo that still don't support these we can try to
deal with that later.

2be964efea If sudo is invoked as "sudoedit" the -e flag is implied and no other 
flags are permitted.

c7d74402f3 Add a new flag, -e, that makes it possible to give users the ability 
to edit files with the editor of their choice as the invoking user,
not the runas user.  Temporary files are used for the actual edit
and the temp file is copied over the original after the editor is done.

8ab5b8c596 If real uid == 0 and the SUDO_USER environment variables is set, 
use that to determine the invoking user's true identity.  That way
the proper info gets logged by someone who has done "sudo su" but
still uses sudo to as root.  We can't do this for non-root users
since that would open up a security hole, though perhaps it would
be acceptable to use getlogin(2) on OSes where this a system call
(and doesn't just look in the utmp file).

063c2812e2 Back out portions of the -i commit that set NewArgv[0] in set_runaspw. 
It is far to late to set NewArgv[0] there and will have no effect
anyway as cmnd and safe_cmnd have already been set.

03f5f4087c Fix a bug when set_runaspw() is used as a callback. We don't want to 
reset the contents of runas_pw if the user specified a user via the -u flag.

Avoid unnecessary passwd lookups in set_authpw().  In most cases we already
have the info in runas_pw.
