Expected behavior

Binary structures (like IMAGE_DOS_HEADER, IMAGE_NT_HEADER, ...) should be mapped by default when analyzing a binary

Actual behavior

Headers are not mapped in memory

Steps to reproduce the behavior

Open an exe with r2, px @ 0x00400000 (if file is mapped at 0x00400000) => not mapped (no MZ magic, ...)

Some people want it some people don't want it. You can just use e io.va=false for now.

[radare]

Nope this doesnt makes the data structures to appear magically

its not about wanting it, its a bug and must be fixed. @Maijin the issue is about the maps not the types

[Maijin]

kk

[radare]

Its about a missing map. Is this issue for ELF only? Or PE is affected too? Should be easy to fix

I noted this issue when analysing a PE. I have no idea for ELF and other stuffs.

[radare]

I have implemented the omo command that should make this map appear but its not yet depriorized when created. Will fix that later today but will be good to do the fix properly in rbin. Because i saw many inconsistent output in -S and -SS after the last changes from @ret2libc and i think we must review that but after the 2.7 release

moving for 2.8 because now we have the omo command that seems to work. tested on a mach0 binary. We will need to import the header parser info and show the header properly. this is where asm.meta joins the game.

@radare what are you referring to?

[radare]

i think that r2 -SS should print something and it does nothing, at least for mach0 binaries, didnt tested more. also r2 -rSS should print om commands, not S ones.

If you have some concrete examples please open an issue and I'll have a look

[radare]

it’s more like random ideas in my head that i have to put in a pad to make real issues and plans for it

Since the automation was "interrupted" by recent tags.. Please do provide additional details about the issue, which includes: a specific binary where the problem happens, the exact commands you use, the exact actual output you see and what you expect to see. Make sure to use an updated version of r2 please.
