The "-l logfile" option can be used to store a log of what
actions cvtsudoers took when merging multiple files.
For example, which aliases were renamed, which entries were overriden
or removed as duplicated.
Previously, we checked that the previous entry's binding pointer
was not the same while freeing. However, to be able to merge
Defaults records we cannot rely on Defaults entries with the same
binding being immediately adjacent. This removes the prev_binding
checks in favor of a reference count which allows us to plug the
memory leak in cvtsudoers when merging Defaults.
This causes "intercept" to be set to true in command_info[] which
the sudo front-end will use to determine whether or not to intercept
attempts to run further commands, such as from a shell. Also add
"log_children" which will use the same mechanism but only log (audit)
further commands.
Previously we needed to include headers required by the various
sudo*h files. Now those files are more self-sufficient and we
should only include headers needed by code in the various .c files.
o The parse tree is now passed to the alias, match and defaults functions.
o The nss API has been changed so that the nss parse() function returns
a pointer to a struct sudoers_parse_tree which will be filled in
by the getdefs() and query() functions.
addition to expand_aliases, input_format and output_format, both
the initial sudoOrder and the increment when updating sudoOrder for
subsequent sudoRole objects can be specified. Command line options
have also been added for the start order and increment.
This makes it possible to convert from LDAP sudoers to a traditional
sudoers file. Semantic differences between file sudoers and LDAP
sudoers mean that LDIF -> sudoers is not completely equivalent.
