5bc294b715 More to a less restrictive, ISC-style license. 2004-02-13 21:36:43 +00:00

4dc5700a6d 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.

7536a781f0 Add support for preloading a shared object containing a dummy execve() 
function that just sets error and returns -1.  This adds a
"noexec_file" option to load the filename as well as a "noexec" flag
to enable it unconditionally.  There is also a NOEXEC tag that can
be attached to specific commands and an EXEC tag to disable it.

a01f25b5f1 Don't assume libc can realloc() a NULL string. 
If malloc/realloc fails, make sure we just return; yyerror() is not terminal.

8b3c38d20c Better fix for sudoers files w/o a newline before EOF. It looks 
like the issue is that yyrestart() does not reset the start condition
to INITIAL which is an issue since we parse sudoers multiple times.

cce84a1811 Work around what appears to be a flex bug when dealing with files 
that lack a final newline before EOF.  This adds a rule to match
EOF in the non-initial states which resets the state to INITIAL and
throws an error.

cf2db3682b o Use exclusive start conditions to remove some ambiguity in the 
lexer.  Also reorder some things for clarity.
 o Add support for "+=" and "-=" list operators.
 o Use the new DEFVAR token to denote a Defaults variable name.

d64ad77515 Allow special characters (including '#') to be embedded in pathnames 
if quoted by a '\\'.  The quoted chars will be dealt with by fnmatch().
Unfortunately, 'sudo -l' still prints the '\\'.

9aeabf1b03 Fully qualified hosts w/ wildcards were not matching the FQHOST token type. 
There's really no need for a separate token for fully-qualified vs.
unqualified anymore so FQHOST is now history and hostname_matches
now decides which hostname (short or long) to check based on whether
or not the pattern contains a '.'.

2eb9882339 o Whenever we get a bare newline we change to the INITIAL state. 
o Enter GOTRUNAS when we see Runas_Alias

This allows #uid to work in a RunasAlias.

818bbacb5d Don't need YY_FLUSH_BUFFER after all 
Move yyrestart() into visudo.c since it might not get called in yywrap
    if we get a parse error (and we only reread the file on error anyway).
 1999-11-09 20:06:53 +00:00
Todd C. Miller
95eb54d99c Call YY_FLUSH_BUFFER macro in yywrap() to clean up any buffers that 
might still exist.
Call yyrestart() instead of using the deprecated YY_NEW_FILE macro.

13bf42675d Add support for "Defaults" line in sudoers to make configuration variables 
changable at runtime (and on a global, per-host and per-user basis).
Both the names and the internal representation are still subject to change.
It was necessary to make sudo_user.runas but a char ** instead of a
char * since this value can be changed by a Defaults line.  There is a
similar (but more complicated) issue with sudo_user.prompt but it
is handled differently at the moment.

Add a "-L" flag to list the name of options with their descriptions.  This
may only be temporary.

Move some prototypes to parse.h

Be much less restrictive on what is allowed for a username.

3a8b0be635 o --with-otp deprecated, use --without-passwd instead 
o real dependencies in the Makefile
o --with-devel option to enable yacc, lex, and -Wall
o style -- "foo -> bar" becomes "foo->bar"
o ALL goes back to being a token, not a string but don't leak memory
o rename hsotspec -> host in parse.yacc

f14dd25b01 Break 'WORD' regexp def into HOSTNAME and USERNAME. These days a 
username can contain just about anything so be very permissive.
Also drop the unused \. punctuation.

d1a6fa810e o Remove some unnecessary backslashes 
o collapse multiple !'s by using !+ and checking if yyleng is even or odd.
  this allows us to simplify ! handling in parse.yacc
