If recvmsg indicates that the message read was truncated libnl retries to read the complete message after increasing the message buffer. This only works if the message flags MSG_PEEK | MSG_TRUNC are set. If NL_MSG_PEEK is not enabled on the nl_sock structure, flags are left empty and the rest of the truncated message is discarded, hence a subsequent recvmsg returns the next message (in case of a multipart message, the NLMSG_DONE) is read and returned. This patch aborts message processing if the message was truncated and the NL_MSG_PEEK flags was not activated for the nl_sock structure. http://lists.infradead.org/pipermail/libnl/2015-June/001888.html [thaller@redhat.com: add NL_CAPABILITY_NL_RECV_FAIL_TRUNK_NO_PEEK] Signed-off-by: Thomas Egerer <hakke_007@gmx.de> Signed-off-by: Thomas Haller <thaller@redhat.com> |
