Rebasing the session

[radare]

We can change the baddr at startup time.. but this is not possible in the middle of a running session. we can use fR to relocate the flags, but this will not change the bininfo, analysis, meta, ...

I think that we should have a command to perform this action, and test it properly, also we should be able to rebase only the metadata from a specific range in memory, if we have more files opened we dont want to relocate everything.

How does wrongly-based metadata get into the session in the first place?

[radare]

?

[kazarmy]

Um ... are there any other reasons to rebase metadata apart from the debugger loading the binary at a different address from previously?

Aslr?

In my case fR didn't work. Binary file - firmware for intel x86 16bit.
Before relocating:

[3000:36fc]> f
0x000336fc 9 str.MainTask
....
[3000:36fc]> pd 1                                       
            ;-- str.MainTask:                           
            3000:36fc     .string "MainTask" ; len=9

Relocating:

[3000:36fc]> fR 0x3000:0x36fc 0x3000:0x4000
Relocated 15 flags                         
[3000:36fc]> f
0x000376fc 9 str.MainTask
...

But it didn't relocate:

[3000:36fc]> pd 1
            ;-- str.MainTask:
            3000:36fc     .string "MainTask" ; len=9
