#273 fixed libpacketdump cannot decode the header following Linux SLL perry salcock
Description

Trying to run tracepktdump on the Wireless 1 trace results in the following output:

tracepktdump -c 1 pcapfile:/trace/wireless/1/wireless-i.pcap.gz 

Fri Mar  7 22:52:16 2008
 Capture: Packet Length: 178/178 Direction Value: 1
 Linux SLL: Packet Type = HOST
 Linux SLL: Hardware Address Type = 0x0323
 Linux SLL: Hardware Address Length = 6
 Linux SLL: Hardware Address = 00:00:02:7b:c4:7f
 Linux SLL: Protocol = 0x0019
tracepktdump: symbol lookup error: /home/salcock/install//lib/libpacketdump/link_6.so: undefined symbol: arphrd_type_to_libtrace

arphrd_type_to_libtrace is only defined locally within the libtrace library. The question is: do we want to make this an external function so that link_6.c can use it, or should we just copy and paste the code for that function into link_6.c and hope we never have to change it?

#274 fixed Libtrace fails to open some compressed files perry salcock
Description

Libtrace does not open compressed trace files created using crl_to_pcap (a libcoral tool). The error occurs when calling pcapfile_start() - attempting to read the pcap header returns Z_STREAM_END which is interpreted to be an EOF.

This generates the helpful error message of "Failed to start trace: No error" :)

There is a trace on wraith:/scratch/salcock/test2.gz which exhibits this behaviour if you need a test case.

#279 fixed tracetop segfaults when it can't open an interface perry Matt Brown
Description

if you run tracetop as a normal user who can't open an interface it segfaults:
