(and I don't know) <pinotree> (yes, and gamin) <youpi> pinotree: you have them already, they're just not stored <youpi> see S_io_reauthenticate <youpi> Throw away the ids we went through all that trouble to get... <youpi> (comment) * pinotree looks <pinotree> hm, and who calls that rpc? <youpi> everybody <youpi> since that's how ext2fs knows the permission to apply, for instance <pinotree> ah, i was referring to the reauthenticate of pflocal, not auth_server_authenticate() <youpi> that's what I'm saying <youpi> see __hurd_file_name_lookup_retry, which is the very internal part of open() <youpi> it calls io_reauthenticate() <youpi> to authenticate itself to the underlying translator of the opened node <pinotree> youpi: so, hm, could be an option make the result of pflocal's S_io_reauthenticate cached in the sock_user struct? <youpi> yes <pinotree> nice thanks, i will try that change first # IRC, OFTC, #debian-hurd, 2013-02-20 <pinotree> youpi: while debugging #700530, it seems that xorg does not have working socket credentials on kfreebsd (and hurd too) <pinotree> julien provided sune with http://people.debian.org/~jcristau/kbsd-peercred.diff to test, but of course that won't work for us (even if we would have working socket credentials with cmsg) <pinotree> (that patch is not tested yet) <pinotree> at least, we're aware there's another place in need for working socket credentials now <youpi> k <pinotree> youpi: (the patch above has been confirmed to work, with s/SOL_SOCKET/0/ ) <youpi> 0 ?! <pinotree> yeah --- See also [[pflocal_reauth]] and [[sendmsg_scm_creds]].
