If libpcap on the host is built with HAVE_TPACKET3 defined (to enable support for TPACKET_V3), the dhcpsnoop code's initialization of the libpcap socket would fail with the following error: virNWFilterSnoopDHCPOpen:1134 : internal error: pcap_setfilter: can't remove kernel filter: Bad file descriptor It turns out that this was because TPACKET_V3 requires a larger buffer size than libvirt was setting (we were setting it to 128k). Changing the buffer size to 256k eliminates the error, and the dhcpsnoop thread once again works properly. A fuller explanation of why TPACKET_V3 requires such a large buffer, for future git spelunkers: libpcap calls setsockopt(... SOL_PACKET, PACKET_RX_RING...) to setup a ring buffer for receiving packets; two of the attributes sent to this API are called tp_frame_size, and tp_frame_nr. If libpcap was built with HAVE_TPACKET3 defined, tp_trame_size is set to MAXIMUM_SNAPLEN (defined in libpcap sources as 262144) and tp_frame_nr is set to: [the buffer size we set, i.e. PCAP_BUFFERSIZE i.e. 262144] / tp_frame_size. So if PCAP_BUFFERSIZE < MAXIMUM_SNAPLEN, then tp_frame_nr (the number of frames in the ring buffer) is 0, which is nonsensical. This same value is later used as a multiplier to determine the size for a call to malloc() (which would also fail). (NB: if HAVE_TPACKET3 is *not* defined, then tp_frame_size is set to the snaplen set by the user (in our case 576) plus a small amount to account for ethernet headers, so 256k is far more than adequate) Since the TPACKET_V3 code in libpcap actually reads multiple packets into each frame, it's not a problem to have only a single frame (especially when we are monitoring such infrequent traffic), so it's okay to set this relatively small buffer size (in comparison to the default, which is 2MB), which is important since every guest using dhcp snooping in a nwfilter rule will hold 2 of these buffers for the entire life of the guest. Thanks to Christian Ehrhardt for discovering that buffer size was the problem (this was not at all obvious from the error that was logged!)

There are two undesirable aspects to the impl - Only a bare wildcard is permitted - The wildcard match is not performed in the order listed Reviewed-by: John Ferlan <jferlan@xxxxxxxxxx> Signed-off-by: Daniel P. Berrangé <berrange@xxxxxxxxxx> commit 96fc9fc5096b9d699c46bfd0baecab68c2138066 Author: Peter Krempa <pkrempa@xxxxxxxxxx> Date: Fri Apr 27 13:17:17 2018 +0200 qemu: migration: Set the 'set' boolean in qemuMigrationParamsSetString The code setting TLS parameters verifies that TLS is supported by looking at the dump of parameters which will be reset after migration, but sets the parameters in the list of new parameters. As qemuMigrationParamsSetString did not set the 'set' property, the TLS parameters would not be used. This is a regression after the series refactoring migration parameters and it resulted into TLS not being used even when requested.
