buck-security hard-codes a number of file locations for the target system on
which it operates and also its own dependencies. These hard-coded dependencies
have been parameterized and a few other related changes have been made. The
changes are more fully explained below.
buck-security.bb:
* The RDEPENDS_${PN} variable has been made more orderly in anticipation of
subsequent changes. It also includes a few other perl modules required by
the changes to the application.
* The functionality.patch file has been removed and superseded by the
take_root_dir.patch patch.
* The definition of S is parameterized on BPN not PN; they are different if the
package has a native option.
* The install step replaces the use directives and an assignment in the
buck-security script in a more general way than previously.
* The recipes now allows the package to have a native version.
take_root_dir.patch:
* buck-security
* An additional flag, sysroot, that specifies the sysroot of the filesystem
that the buck-security utility inspects is added. If the sysroot can not
be located the script fails gracefully.
* An additional flag, no-sudo, which prevents the script from exiting
if it is not run by root is added.
* An additional flag, disable-checks, which accepts a comma-separated list
of checks to be disabled is added.
* The script checks whether there has been an error in parsing the
command-line arguments and fails with a usage message if there has.
* The log flag now optionally takes a log file name.
* The location of the configuration file is calculated relative to the
location of the main script and if it can not be found the script fails
gracefully.
* The various file locations specified in the buck-security configuration
file are made relative to the location of the buck-security script or the
sysroot as appropriate.
* If a log file has been specified the log is not also printed to stdout.
* The command actually executed is printed in the log.
* Some checks for mutually exclusive options are added.
* Output level 3 is now meaningless, so it has been removed.
* Various changes have been made to the report format.
* Results are sorted lexicographically and, if abspath, do not include
the sysroot.
* checks/*.pm files
* Wherever a directory had been hard-coded it is now parameterized on the
sysroot.
* In some cases, a test that had previously been run as a bash test was
converted to a perl test to allow better handling of results and errors.
* The output parameter is no longer accepted by the check procedure since
this value is global.
* All check procedures now accept an output_type parameter.
* The dangling URLs are removed from the help text.
* checks/lib/check.pm
* The CheckBash and CheckPerl functions have been adapted so that the
the filepaths are not hard-coded and so that the actual command is made
available to the logging component.
* A parameter indicating the outcome type is accepted and passed to the
exception checker.
* Error output is clearly distinguished from regular output.
* A failure in a test is clearly distinguished from an insecure result.
* The output is no longer formatted in the check functions.
* checks/lib/mkchecksum.pm
* The command no longer is run on non-existent directories.
* checks/lib/exceptions.pm
* The exception file path is located relative to the buck-security script.
* If the exceptions are pathnames, the sysroot is prepended.
* Correct wildcard semantics is observed.
* checks/lib/users.pm
* The passwd files are located relative to the sysroot.
* Reading from the password file is made more principle.
* The test experiences an error if files can not be found rather than
the script terminating.
* Some dead code is eliminated.
* conf/buck-security.conf
* The checksum_dir variable is a list instead of a string for easier
manipulation.
* The new configuration variable sysdir is added and the default is /.
* The ssh_config variable is added.
* All tests are included in the checks variable.
* checks/sshd.pm
* The ssh config file is set in the buck-security configuration file
instead of hard-coded here.
* checks/nopasswd.pm
* This is a duplicate of emptypasswd, so it is removed.
* RDEPENDS_${PN}_class-native variable is added as some tasks make no
sense when run externally. Since they will not be run, there is no point
