I can't recall any clear indication that this is for internal purposes (and can't find any mention of this now), but there is explicit check in keyctl.c:key_get_type_from_user and it is used for ".request_key_auth" key type. Judging by commit messages for 54e2c2c1, 1260f801 and 3e30148c, it is indeed reserved for internal purposes and has been reserved as part of the introduction of the aforementioned ".request_key_auth" key type. > Cheers, > > Michael > > >> +.TP >> +.B EPERM >> +.I type >> +was >> +.I """keyring""" >> +and the >> +.I description >> +started from dot. >> .SH VERSIONS >> This system call first appeared in Linux 2.6.10. >> .SH CONFORMING TO >> > > > -- > Michael Kerrisk > Linux man-pages maintainer; http://www.kernel.org/doc/man-pages/ > Linux/UNIX System Programming Training: http://man7.org/training/ -- Eugene "eSyr" Syromyatnikov mailto:evgSyr@xxxxxxxxx xmpp:eSyr@jabber.{ru|org} -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
