#20 fixed Buy air bed perry matt@…
Description

I cannot use tracemerge to join two files that were generated from tracesplit. I get a segfault resulting in the following backtrace

#21 fixed tracemerge cannot write erf files when using -i from pcap input perry matt@…
Description

When using the -i option in conjunction with a PCAP input trace and ERF output traces an error occurs as shown below.

matt@argon:~$ tracemerge -i erf:new.erf pcap:out.pcap pcap:in.pcap
trace_write_packet((null)): No erf type for packet

The problem occurs because when trace_set_direction is set on a packet read from a pcap trace the packet is promoted to the LINUX_SLL type. This type is not handled by the erf output routines, libtrace_to_erf_type in linktypes.c particularly, leading to the error shown above.
