ca6eddf0df Replace the double fork with a fork + daemonize. 2008-06-22 20:19:42 +00:00

5756ddfbeb Change how the mailer is waited for. Instead of having a SIGCHLD 
handler, use the double fork trick to orphan the child that opens
the pipe to sendmail.  Fixes a problem running su on some Linux distros.

552eca0d0f Ignore SIGPIPE instead of blocking it when piping to the mailer. If we 
only block the signal it may be delivered later when we unblock.
Also, there is no need to block SIGCHLD since we no longer do the
double fork.  The normal SIGCHLD handler is sufficient.

b7b807e107 Block SIGPIPE in send_mail() so sudo is not killed by a problem 
executing the mailer.

0f9e7f96f4 Add mailfrom Defaults option that sets the value of the From:

the invoking user is used.

ff0a538d04 Call cleanup() before exit in log_error() instead of calling 
sudo_ldap_close() directly.  ldap_conn can now be static to sudo.c

a766300007 Set aux group vector for PERM_RUNAS and restore group vector for 
PERM_ROOT if we previously changed it.  Stash the runas group vector
so we don't have to call initgroups more than once. Also add no-op
check to check_perms.

f9f4aca556 Add support for runas groups. This allows the user to run a command 
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.
TODO: implement runas group for ldap
      improve runas group documentation
      add testsudoers support

the command is prefixed with the SETENV tag.

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

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.

27ad285a03 Also exit waitpid() loop when pid == 0. Fixes a problem where the sudo 
process would spin eating up CPU until sendmail finished when it has
to send mail.

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".
