Bitfield with negative bit_position value #49

Closed IridiumXOR closed 8 months ago

IridiumXOR commented 1 year ago

Hi, generating the json profile for vmlinux-5.19.0-40-generic Ubuntu 22.04 stock kernel I have discovered that the tool produce a negative bit_position value for bitfields (example for field active_mode in struct Scsi_Host. I think the problem come from this line: https://github.com/volatilityfoundation/dwarf2json/blob/c306d1132f014dc882ffc0ad22e97764bae49451/main.go#L290

Please can you fix it?

Shiselster commented 1 year ago

I tend to believe the issue stems from differences between DWARF Version 4 and DWARF Version 5, the latter probably not supported by dwarf2json yet?

Happens to me too (only on DWARF Version 5), any intention to fix it?

Issue seems to be fixed after commit https://github.com/volatilityfoundation/dwarf2json/pull/58/commits/9673739daf497a6ebc835f6dcb8f74de19d9e8ba!!

Great job @mkonshie! Any plans to merge https://github.com/volatilityfoundation/dwarf2json/pull/58 back into master?
