Interpretación de banderas en el informe diario de la AIDE

Interpretación de banderas en el informe diario de la AIDE

Mi pregunta es sobre las banderas que muestra AIDE para cada archivo en los informes diarios por correo electrónico. Por ejemplo, para archivos nuevos se muestra de la siguiente manera:

f++++++++++++++++: /var/cache/apt/archives/squashfs-tools_1%3a4.4-1ubuntu0.1_amd64.deb

Puedo deducir que fsignifica archivo y he visto dcuál significa directorio. ¿Pero qué otras banderas podrían venir aquí? ¿Qué pasa con el ++++++++++++++++? ¿Significa algo?

Ahora las cosas son más interesantes para los archivos modificados:

d =.... mc.. ..  : /run/motd.d/fwupd
f =.... mci....  : /run/motd.d/fwupd/85-fwupd
f >b... mc..C.. .: /var/cache/apt/pkgcache.bin
f <.... mc..C.. .: /var/cache/apt/srcpkgcache.bin
f =.... .c..... .: /var/lib/PackageKit/transactions.db

No pude encontrar ninguna documentación con detalles de lo que esto significa. Cualquier ayuda para entender esto es muy apreciada.

Las banderas se describen en la aide.confpágina del manual (ver man 5 aide.conf):

       report_summarize_changes (type: bool, default: true)
       summarize_changes (DEPRECATED, will be removed in a future release)
              Summarize changes in the added, removed and changed files sections of the report.

              The general format is like the string YlZbpugamcinHAXSEC, where Y is replaced by the file-type (f for a regular file, d for a directory, l for a symbolic link, c for a character device, b for a block device, p for a FIFO, s for a unix socket, D for  a
              Solaris door, P for a Solaris event port, !  if file type has changed and ? otherwise).

              The Z is replaced as follows: A = means that the size has not changed, a < reports a shrinked size and a > reports a grown size.

              The other letters in the string are the actual letters that will be output if the associated attribute for the item has been changed or a "." for no change, a "+" if the attribute has been added, a "-" if it has been removed, a ":" if the attribute is
              ignored (but not forced) or a " " if the attribute has not been checked. The exceptions to this are: (1) a newly created file replaces each letter with a "+", and (2) a removed file replaces each letter with a "-".

              The attribute that is associated with each letter is as follows:

              o      A l means that the link name has changed.

              o      A b means that the block count has changed.

              o      A p means that the permissions have changed.

              o      An u means that the uid has changed.

              o      A g means that the gid has changed.

              o      An a means that the access time has changed.

              o      A m means that the modification time has changed.

              o      A c means that the change time has changed.

              o      An i means that the inode has changed.

              o      A n means that the link count has changed.

              o      A H means that one or more message digests have changed.

              The following letters are only available when explicitly enabled using configure:

              o      A A means that the access control list has changed.

              o      A X means that the extended attributes have changed.

              o      A S means that the SELinux attributes have changed.

              o      A E means that the file attributes on a second extended file system have changed.

              o      A C means that the file capabilities have changed.
