0f60107a1c No need for dump_badenv() now that dump_defaults() knows how to dump lists. 2002-05-05 19:58:29 +00:00

3f7d801880 Don't try to pre-compute the size of the new envp, just allocate 
space up front and realloc as needed.  Changes to the new env pointer
must all be made through insert_env() which now keeps track of
spaced used and allocates as needed.

a576207620 Use easprintf instead of emalloc + sprintf for some things. 2002-04-18 15:38:52 +00:00

ea24bef19c The SHELL environment variable was preserved from the user's 
environment instead of being reset based on the passwd database
when the "env_reset" option was used.  Now it is reset as it should be.

existing parser.

2cbd965d63 o Remove assumption that PATH and TERM are not listed in env_keep 
o If no PATH is in the environment use a default value
o If TERM is not set in the non-reset case also give it a default
  value.

199a17436d o Convert environment handling to use lists instead of strings. 
This greatly simplifies routines that need to do "foreach" type
   operations.
 o Add new init_envtables() function to set env_check and env_delete
   defaults based on initial_badenv_table and initial_checkenv_table
   (formerly sudo_badenv_table).

65302649f5 Add support for '*' in env_keep when not resetting the environment 
(ie: the normal case).

ab020c056b Add env_delete variable that lets the user replace/add to the bad_env_table. 
Allow '*' wildcard in env_keep entries.

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)
