Build log

Compilation errors are of the form:

    /var/tmp/portage/sys-fs/aufs3-3_p20130318/work/aufs3-standalone/fs/aufs/i_op.c: In function ‘aufs_setattr’:
    /var/tmp/portage/sys-fs/aufs3-3_p20130318/work/aufs3-standalone/fs/aufs/i_op.c:719:8: error: incompatible type for argument 2 of ‘security_path_chown’

Full build log is attached.

I should add, I have CONFIG_USER_NS enabled, because I want to make use of lxc.

[Comment 3 Justin Lecher (RETIRED) 2013-03-27 17:44:08 UTC]

could you please try to use sys-kernel/aufs-sources as you are using gentoo source with aufs.

aufs-sources .config

I get the same thing when I try to build aufs-sources:

fs/aufs/i_op.c: In function ‘aufs_setattr’:
fs/aufs/i_op.c:719:8: error: incompatible type for argument 2 of ‘security_path_chown’
include/linux/security.h:2936:19: note: expected ‘kuid_t’ but argument is of type ‘uid_t’

include/linux/security.h:2936:19: note: expected ‘kgid_t’ but argument is of type ‘gid_t’
fs/aufs/i_op.c: In function ‘au_refresh_iattr’:

include/linux/fs.h:710:20: note: expected ‘gid_t’ but argument is of type ‘kgid_t’

Can I ask, why does the sys-fs/aufs package exist if not to be used with gentoo-sources?

I've attached my aufs-sources .config.

I will test that.

you can, but aufs-sources are much simpler.

[Comment 6 Justin Lecher (RETIRED) 2013-03-28 10:45:33 UTC]

I reported it upstream.

[Comment 7 Justin Lecher (RETIRED) 2013-03-28 12:35:57 UTC]

Quoting upstream:

justin:

Confirmed.
The type of the parameter was changed in linux-3.7. I didn't aware of
it.
The fix will be released in next Monday.

The problem still appears to be present on sys-kernel/afs-sources-3.8.5. Any progress on this issue?

[Comment 9 Justin Lecher (RETIRED) 2013-04-02 16:05:17 UTC]

not yet. still not fixed upstream.
