linux_proc_maps AttributeError: Struct mnt has no member mnt_parent #373

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

1. Boot Lubuntu 12.10 64bit Live then mount a HD partition via pcmanfm
2. Dump memory to the mounted drive partition
3. Create a profile for your Live environment.
4. Audit *.lime with linux_tmpfs -L

What is the expected output?

Should be a list of memory maps for processes.

What do you see instead?

Please provide any additional information below.

linux_lsof reports the same error as linux_proc_maps.
linux_mount reports the same error as linux_tmpfs -L.

Hello,

Can you please download svn trunk and try? This issue should be fixed in it 
since about a month ago (we had a similar report then). All of those plugins 
are breaking because they are inheriting same function, so they should all be 
fixed at once.

I downloaded the svn trunk and still have issues with 3 out of 4 of the 
plugins. linux_proc_maps is working while the rest are displaying the keyerror.

I'm including a similar issue from another plugin, linux_find_file.

Hello,

Can you please svn update and then rebuild the profile for your machine? The 
plugins should then work with the new profile. I will leave the issue opened 
until you report as fixed.

Hi peeknmod, its been a few days so we're going to assume this is working 
properly at this time. If you find otherwise, please do re-open or create a new 
ticket and we'll get back to you asap. 

Thanks!
