- one can write record/s to pipe in following format - "%s %ul %64s\n" - it contains full path, size and sha256 hash - each record has to be terminated with new line character - size of the record is limited by size of the buffer which is 4096 - one can write "2" to the pipe and daemon will flush all cache - it is recommended to refresh the caches after some addition Signed-off-by: Radovan Sroka <rsroka@redhat.com>

Fapolicyd (File Access Policy Daemon) implements application whitelisting to decide file access rights. Applications that are known via a reputation source are allowed access while unknown applications are not. The rpm plugin allows us to use rpm database as a source of trust. We used dnf plugin since the beggining but it only provides notification when transaction ends. With "integrity checking" requirement we need a continual addition of files which are installed during the system update. With fapolicyd rpm plugin we can allow using of recently added/updated files in scriptlets during rpm transaction. The fapolicyd plugin gathers metadata of currently installed files. It sends the information about files and about ongoing rpm transaction to the fapolicyd daemon. The information is written to Linux pipe which is placed in /var/run/fapolicyd/fapolicyd.fifo. The data format is "%s %lu %64s\n". [path, size, sha256] The fapolicyd rpm plugin can be enabled with "--with-fapolicyd" configure option.
