17514b55ea Add support for multiple '*' in env_keep, env_check and env_delete 
entries.

b3af85ddc8 Add restricted_env_file which is like env_file but subject to the 
same restrictions as the user's own environment.

deb4c3b19c In sudo_unsetenv_nodebug(), decrement envp.env_len after removing 
the variable.  From Paul Zirnik of SUSE.

dbd5252798 Fix incorrect strncmp() lengths. The check for USERNAME was only 
looking at the first 5 characters (copy and paste error).  The check
for SUDO_PS1 was not checking the trailing '=' character (off by
one error).  Found by PVS-Studio.

4c8988d483 When checking for old-style bash functions in the environment, check 
for values starting with "() " (note the trailing space) rather
than "()".  Bash will only treat the value as a function if the
space after "()" is present.  The trailing space was already present
in the compare string but when it was added, the length passed to
strncmp() was not updated from 3 to 4.
Found by PVS-Studio.  No security impact.

3f022419ae Be consistent with the naming of the variable used to store the 
function return value.  Previously, some code used "rval", some
used "ret".  This standardizes on "ret" and uses "rc" for temporary
return codes.

17ad75d50b Add a flags option to sudo_parseln() and a flag to only mach comments 
at the beginning of the line.  Use the flag when parsing ldap.conf.

21d6fc3d8f Simple garbage collection (really a to-be-freed list) for the sudoers 
plugin.  Almost identical to what sudo.c uses.  Currenly only the
environment strings are collected at exit time which is enough to
quiet address sanitizer's leak detector.

9c0354730a When preserving variables from the invoking user's environment, if 
there are duplicates only keep the first instance.

588460405f For env_reset, SHELL should be set based on the target user, not 
the invoking user unless preserved via env_keep.

29a3fcd06c If some, but not all, of the LOGNAME, USER or USERNAME environment 
variables have been preserved from the invoking user's environment,
sudo will now use the preserved value to set the remaining variables
instead of using the runas user.  This ensures that if, for example,
only LOGNAME is present in the env_keep list, that sudo will not
set USER and USERNAME to the runas user.

0b241088b3 There's no need to conditionalize the #include <unistd.h>, we require

caf5d45e0f Previously, debug_return_bool was the same as debug_return_int 
except that it logged true/false for 1/0.  However, this appears
to trigger a bug in some compilers.  To avoid this, debug_return_bool
now uses bool, not int.  Callers that were passing it an int have
been converted to use debug_return_int instead.

c3c28773f5 Sanity check the TZ environment variable by special casing it in 
env_check.  The --with-tzdir configure option can be used to
specify the zoneinfo directory if configure doesn't find it.

systems doesn't include stdint.h itself.

866cfc4fc3 Add support for multiple Debug lines per program. Callers may 
register arbitrary debug facilities or use built-in defaults.  We
now use separate Debug statements for plugins and programs.

c49ca1d315 Don't allow pam_env to overwrite existing variables when env_reset 
is disabled unless the variables match the black list and would
normally be removed.  It may just be better to never overwrite when
env_reset is disabled.

df0fd41530 Add explicit support for matching the full environment string 
(name=value).  Bash functions may now be preserved for full matches,
but not for name-only matches.

then calls gettext().
Add U_ macro that calls warning_gettext() instead of gettext().
