neightbl_dump_info and neigh_dump_table can skip entries if the *fill*info functions return an error. This results in an incomplete dump ((invoked by netlink requests for RTM_GETNEIGHTBL or RTM_GETNEIGH) nidx and idx should not be incremented if the current entry was not placed in the output buffer Signed-off-by: Gautam Kachroo <gk@aristanetworks.com> --- It looks like the problem crept in with commit 426b5303eb435d98b9bee37a807be386bc2b3320 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
