c54bdd799b Return AUTH_* flags from check_user() instead of 1/0/-1. 2023-09-09 14:59:46 -06:00

2fdb4db339 Wrap valid_shell and add to sudo_pwutil_set_backend(). 
This will make it possible to support a different getusershell()
implementation for testsudoers in the future.

d18ee8e0e7 Move check_user_shell() to pwutil.c as user_shell_valid() 
This will make it possible to support a different backend which may
be used by testsudoers in the future.

956de5cbbc sudoers_sethost: refactor code to set host names in sudoers_context. 
The sudoers_sethost() function can be shared by the sudoers plugin,
visudo, cvtsudoers and testsudoers.

3c05e748a4 Add ignore_perms plugin argument to skip the sudoers file security checks. 
This is not intended to be used in a production environment.

30fc288291 Move tty_present() into policy.c as sudoers_tty_present(). 
This function is policy-dependent.  For the modern sudo front-end
it will simply check tcpgid and/or ttypath.

c7157ce0b1 Move a few fields from sudoers_user_contect to sudoers_context. 
They are not really specific to the user or user-specified.

87571dab0a Add struct sudoers_conf to struct sudoers_plugin_context. 
There's now no need to pass this directly to init_parser() since we
already pass in a pointer to a sudoers_context struct.
 2023-08-21 09:21:54 -06:00

9e53d903ea Store policy paths in struct sudoers_context. 
This removes the need for the getters in policy.c.

bbaf293912 Add sudoers_ctx_free() and use it for freeing struct sudoers context. 
This replaces sudoers_user_ctx_free() and sudoers_runas_ctx_free().

2440174954 Make struct sudoers_context private to sudoers.c. 
We now pass a pointer to the context where necessary.  There are a
few cases where we need to request the context from sudoers via
sudoers_get_context() for the plugin API functions.  If the plugin
API was able to pass around a closure pointer this would not be
necessary.

2d2529a15e Add a sudoers_context struct that embeds the user and runas structs. 2023-08-20 16:27:08 -06:00

20baa39007 Move max_groups out of sudoers_user_context and into pwutil.c. 
It is only used by the local password pwutil implementation.

737354390c Pass in directory to check_user_runchroot() and check_user_runcwd(). 
This way we do not rely on the runas_ctx global.

bd8cccb5dd Rename struct sudo_user -> struct sudo_user_context. 
Also rename the sudo_user global to user_ctx.

The JSON logs will store the matching rule source.

01ad570e24 Move check_user_* functions to check_util.c so testsudoers can use them. 2023-06-30 10:43:18 -06:00

f352ef5d67 Move parser prototypes / externs from sudoers.h to parse.h or toke.h. 2023-05-09 14:01:41 -06:00

8cbd5462a6 Move sudoers search path to struct sudoers_parser_config. 
That way we can avoid passing it to init_parser() directly.
We still need sudoers_search_path to be shared between the lexer
and the parser.
 2023-05-08 17:04:38 -06:00
Todd C. Miller
9d7c30c5a8 Add struct sudoers_parser_config and pass it to init_parser(). 
This struct contains parser configuration such as the sudoers file
uid/gid/mode and parse flags such as verbose, strict and recovery.

c0fa3a4d24 Rename force_umask to override_umask and make it private to sudoers.c. 
Add getter for policy.c.

d5de5890f5 Make login_style private to bsdauth.c 
Add a setter for policy.c to handle auth_type from the front-end.
 2023-05-04 13:06:09 -06:00

80768ed3a8 Make path_ldap_conf and path_ldap_secret private to policy.c. 
Add getters for both so the ldap code can access them.

Todd C. Miller
f553ddc430 Make sudoers_file private to policy.c and visudo.c. 
We just need a way for the policy (and visudo) to override the
default sudoers path.  This adds a getter to be used in file.c when
sudoers is first opened.

f17b35471f Support sudoers_file being a colon-separated path of files. 
The first file found is used.

d7b8f3ffbf Split up the monolithic sudoers_policy_main() function. 
This splits the code to find the command, perform a sudoers lookup,
ask for a password as needed, and perform post-lokup checks out
into sudoers_check_common().  The old sudoers_policy_main() has
been replaced by sudoers_check_cmnd() (called by sudoers_policy_check()),
sudoers_validate_user() (called by sudoers_policy_validate()) and
sudoers_list() (called by sudoers_policy_list()).  The list_user
lookup is now performed in sudoers_list().

Todd C. Miller
8049e4e32f Replace sudoers_warnings with sudoers_verbose. 
This is now an int, with values > 1 reserved for visudo.

0ef5373678 Add canon_path(), a realpath() wrapper that performs caching. 
This also adds a new user_cmnd_dir variable that stores the
canonicalized parent directory of the command to be run.

bff4e3ce16 set_cmnd_path: apply runchroot if set when finding the command path 
Previously we would prepend runchroot to the path we were checking
but that does not properly handle symbolic links.

13a311bc71 Add pivot_root() and unpivot_root() to switch the root dir and restore it. 
This will be used to more accurately handling command resolution and
path matching when a new root directory is specified.

0865e61d9e Pass back the number of files to edit when using sudoedit. 
The sudo front-end can use this to determine where the list of files
to edit begins.
