I've upgraded gentoo source to gentoo-sources-3.10.7-r1, compiled and aufs3 doesn't work anymore, it needs some symbols (do_splice_to, do_splice_from, etc) So by looking at changelog I think it may be related to the security fix, I'm not sure these symbols has to be exported or now (so aufs3 needs an update) but I see some .rej files in the source tree: ./security/commoncap.c.rej ./security/device_cgroup.c.rej ./security/security.c.rej ./fs/splice.c.rej ./fs/namespace.c.rej ./fs/open.c.rej ./fs/inode.c.rej ./fs/file_table.c.rej ./fs/notify/group.c.rej ./fs/notify/mark.c.rej ./include/linux/splice.h.rej ./include/linux/fs.h.rej could you looks please? Reproducible: Always
All genpatches patches apply clean, no rejs. None of the patches touch do_splice. 1) Which version are you upgrading from? 2) Have you tried to rebuild aufs3? 3) Which version of linux-headers? Try 3.10? 4) Which version of aufs3 is this?
1) upgrading from 3.10.7 to 3.10.7-r1, I see .rej files even re-emerging the package from scratch 2) the module builds fine but it cannot be loaded because of non exported symbols 3) currently linux-headers-3.9 so far I've tested: - emerged linux-headers-3.10 - unmerged gentoo-sources - removed /usr/src/linux-3.10.7-gentoo-r1 - emerged again gentoo-sources (3.10-7-r1) - genkernel - emerged aufs3-3_p20130915 >>> Installing (1 of 1) sys-fs/aufs3-3_p20130915 * Removing sys-fs/aufs3-3_p20130915 from moduledb. * Updating module dependencies for 3.10.7-gentoo-r1 ... depmod: WARNING: //lib/modules/3.10.7-gentoo-r1/misc/aufs.ko needs unknown symbol update_time depmod: WARNING: //lib/modules/3.10.7-gentoo-r1/misc/aufs.ko needs unknown symbol do_splice_to depmod: WARNING: //lib/modules/3.10.7-gentoo-r1/misc/aufs.ko needs unknown symbol __mnt_drop_write depmod: WARNING: //lib/modules/3.10.7-gentoo-r1/misc/aufs.ko needs unknown symbol files_lglock depmod: WARNING: //lib/modules/3.10.7-gentoo-r1/misc/aufs.ko needs unknown symbol do_splice_from depmod: WARNING: //lib/modules/3.10.7-gentoo-r1/misc/aufs.ko needs unknown symbol do_truncate [ ok ] 4) aufs3-3_p20130915 aufs-headers-3.11_p20130915 aufs-util-3.9_p20130915
ok, looks like the problem is aufs3 package tries to patch kernel sources but if fails, perhaps why emerge says ok?

It says "ok" because these are just warnings; regardless, assigning to aufs3 maintainers because this is likely something they will want to look into. At least on our side, I don't see anything wrong and have cross checked everything.
Please user aufs-sources which are gentoo-sources+aufs3.
yes I think it's an aufs3 bug, the package needs to be updated with latest patches
(In reply to Gianluigi Tiesi from comment #6) > yes I think it's an aufs3 bug, the package needs to be updated with latest > patches The aufs3 code in the standalone and in the kernel source package are the same. So it's a patching problem on your side, which you can avoid by using aufs-sources.
