4.18-stable review patch. If anyone has any objections, please let me know.
------------------ From: Samuel Mendoza-Jonas <[email protected]> [ Upstream commit 3d0371b313b84ba7c16ebf2526a7a34f1c57b19e ] The ncsi_pkg_info_all_nl() .dumpit handler is missing the NLM_F_MULTI flag, causing additional package information after the first to be lost. Also fixup a sanity check in ncsi_write_package_info() to reject out of range package IDs. Signed-off-by: Samuel Mendoza-Jonas <[email protected]> Signed-off-by: David S.
