I am tryin to open BLF file in Wireshark Version 4.2.5 (v4.2.5-0-g4aa814ac25a1). File contains data from CAN and LIN protocols. CAN data is shown fine, while LIN data is not shown. IN Vector CANoe, all data is shown correctly. LIN data is saved in form of BLF_OBJTYPE_LIN_MESSAGE2 and it is supposed to be implemented by this merge: https://gitlab.com/wireshark/wireshar...

That a mess with all the commits. :-(

If you look at the top of this specific commit, it didn't get put into the 4.2.x branch.

v4.3.0rc1 is available from the Download page.
Or try a development build from the automated builds.

As this was a dissector improvement\change rather than a bugfix it wouldn't normally be backported to the stable release.

In the current release, they are supported, but only in BLF_OBJTYPE_LIN_MESSAGE objects. BLF_OBJTYPE_LIN_MESSAGE2 objects aren't supported.

In the development branch for the next release, BLF_OBJTYPE_LIN_MESSAGE2 are supported. However, BLF files that have raw objects, rather than log containers, at the top level are not supported, regardless of what protocols are in the file, even in that branch.
