staging/lustre: remove IOC_LIBCFS_PING_TEST ioctl

2015-12-06T22:50:59Z

The ioctl IOC_LIBCFS_PING_TEST has not been used in ages. The recent nidstring changes which moved all the nidstring operations from libcfs to the LNet layer but this ioctl code was still using an nidstring operation that was causing a circular dependency loop between libcfs and LNet.

Pull vfs fixes from Al Viro: "A couple of fixes (-stable fodder) + dead code removal after the overlayfs fix. I agree that it's better to separate from the fix part to make backporting easier, but IMO it's not worth delaying said dead code removal until the next window" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: Don't reset ->total_link_count on nested calls of vfs_path_lookup() ovl: get rid of the dead code left from broken (and disabled) optimizations ovl: fix permission checking for setattr

Don't reset ->total_link_count on nested calls of vfs_path_lookup()

we already zero it on outermost set_nameidata(), so initialization in path_init() is pointless and wrong. The same DoS exists on pre-4.2 kernels, but there a slightly different fix will be needed. Cc: stable@vger.kernel.org # v4.2 Signed-off-by: Al Viro

ovl: fix permission checking for setattr

2015-12-06T17:28:23Z

[Al Viro] The bug is in being too enthusiastic about optimizing ->setattr() away - instead of "copy verbatim with metadata" + "chmod/chown/utimes" (with the former being always safe and the latter failing in case of insufficient permissions) it tries to combine these two. Note that copyup itself will have to do ->setattr() anyway; _that_ is where the elevated capabilities are right. Having these two ->setattr() (one to set verbatim copy of metadata, another to do what overlayfs ->setattr() had been asked to do in the first place) combined is where it breaks.
