with a different effective group.  If the -g option is specified
without -u the command will be run as the current user (only the
group will change).  the -g and -u options may be used together.

d72778832c Move list manipulation macros to list.h and create C versions of 
the more complex ones in list.c.  The names have been down-cased
so they appear more like normal functions.

d1dbe2ecee Change list head macros to take a pointer, not a struct. 2007-08-31 01:12:50 +00:00
Todd C. Miller
8cdea0b941 Use a list head struct when storing the semi-circular lists and 
convert to tail queues in the process.  This will allow us to
reverse foreach loops more easily and it makes it clearer which
functions expect a list as opposed to a single member.

Add macros for manipulating lists.  Some of these should become functions.

When freeing up a list, just pop off the last item in the queue instead
of going from head to tail.  This is simpler since we don't have to
stash a pointer to the next member, we always just use the last one
in the queue until the queue is empty.

Rename match functions that take a list to have list in the name.
Break cmnd_matches() into cmnd_matches() and cmndlist_matches.

304dc46d7f Add efree() for consistency with emalloc() et al. Allows us to rely 
on C89 behavior (free(NULL) is valid) even on K&R.

0cddfc3684 Change an occurence of user_matches() -> runas_matches() missed previously 
runas_matches(), host_matches() and cmnd_matches() only really need to pass in
a list of members.  user_matches() still needs to pass in a passwd struct
because of "sudo -l"

2c2daa8eca Use: #include <config.h>

51375f969f Add local error/warning functions like err/warn but that call an additional 
cleanup routine in the error case.  This means we no longer need to compile
a special version of alloc.o for visudo.

02f37dc2da Add support for tuples in def_data.in; these are implemented as an 
enum type.  Currently there is only a single tuple enum but in the
future we may have one tuple enum per T_TUPLE entry in def_data.in.
Currently listpw, verifypw and lecture are tuples.  This avoids the
need to have two entries (one ival, one str) for pwflags and syslog
values.

lecture is now a tuple with the following values: never, once, always

We no longer use both an int and string entry for syslog facilities
and priorities.  Instead, there are logfac2str() and logpri2str()
functions that get used when we need to print the string values.

6ad252765b Create def_* macros for each defaults value so we no longer need 
the def_{flag,ival,str,list,mode} macros (which have been removed).
This is a step toward more flexible data types in def_data.in.

dcf1a5acce Use warn/err and getprogname() throughout. The main exception is 
openlog().  Since the admin may be filtering logs based on the
program name in the log files, hard code this to "sudo".

8dc87eeb22 o Roll our own loop instead of using strpbrk() for better grokability 
o When adding to a list we must malloc() and use memcpy(), not strdup()
  since we must only copy len bytes from str.

2f818e2c32 o Add a new LIST type and functions to manipulate it. 
o This is for use with environment handling variables.

   initialize the environment lists.

(to be expired manually by the user).

d956d77528 Move defaults info into its own files from which we generate 
.h and .c files.  This makes adding or rearranging variables
much simpler.

998631b73a New Defaults options: 
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)

7ea65e54bd Move set_perms() to its own file and use POSIX saved uid or setreuid() 
if available.

Added stay_setuid option for systems that have libraries that perform
extra paranoia checks in system libraries for setuid programs (ie:
anything with issetugid(2)).
