Have a snapshot length of 0 in a capture_file structure mean "there is

that case, a value of 0 mean "no, we don't have a snapshot length".
In dumpcap, start out with a pipe buffer size of 2KB, and grow it as
necessary. When checking for a too-big packet from a pipe, check
against the appropriate maximum - 128MB for DLT_DBUS, 256KB for
everything else.

Unfortunately, only one libpcap code path puts the CAN ID in the
SocketCAN header in network byte order; the others leave it in host byte
order. Therefore, a new LINKTYPE_/DLT_ value was introduced, and
libpcap was changed to use that for the cases where the CAN ID is in
host byte order. Support them both.
This means we need to, when reading pcap and pcapng files, fix up the
CAN ID if the host that wrote the file has a different byte order from
ours (as libpcap also now does). This includes Linux "cooked" captures,
which can include CAN packets.

Set len and caplen in pcap_read_post_process to actual wlen/payload length like for native ERF.
This fixes padding incorrectly showing as an Ethernet trailer or equivalent as
well as packet length calculations being incorrect.
Fix up rlen when writing ENCAP_ERF so it isn't longer than the actual record
length. This differs from native ERF behaviour which pads the record instead
but there is currently no non-hackish way to do this for pcap/pcap-ng.
Note: This means records captured from a DAG card in Wireshark (or old
PCAP(-NG) files opened) will have padding stripped when saved as PCAP(-NG) and
thus cannot be transmitted when converted to native ERF without aligning first.
However, if the file is saved as native ERF originally the padding will be
preserved (and zeroed). Given that extension header write support was very
broken and transmission of PCAP(-NG) is not supported without conversion this
is not expected to have been common.

Truncate final ERF extension header when too many. Rlen is not currently

check against PCAP incl_len anyway as there are other scenarios where this can
happen like naive snapping or Wireshark ERF-to-PCAP.
Properly fixing this will involve getting rid of the ERF pseudoheader.
