uasm ubuntu focal repo package highly wip experiment

[KradMoonRa]

I got some time to spend building uasm 2.50 and repackaging for ubuntu packages installs.

This build it install in /usr/bin and has macrolib in separate include files that's going to install in /usr/include/uasm

if your using the HLL

Add to your uasm comandline

Code Select Expand

-I /usr/include/uasm
Or add to path

Code Select Expand

sudo export PATH="$PATH:/usr/include/uasm"

Add to you code

Code Select Expand

include macrolib.inc

The new code it's not documented yet, but it will be in future.

What you will need to install in ubuntu focal:

add sign key

Code Select Expand

sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xc3aa60f8ba7f9354

Create the file

Code Select Expand

sudo nano /etc/apt/sources.list.d/navegos-uasm-2.50-focal.list with the following content:

Update ubuntu

Installed well on kali linux 

But the new version does not accept PROTO, and generates the first error

     Error A2169: General Failure

Code Select Expand

malloc proto :dword

p0  proto  fastcall :qword ; OK
p1 proto  c :qword         ; OK
p2 proto  stdcall :qword   ; OK
p  proto                  ; OK
p4 proto   :qword         ; ---->  Error A2169: General Failure
p3 proto  systemv :qword   ; ----> Error A2169: General Failure

It was not in the previous version

Hi KradMoonRa,

very useful stuff, thanks!

Hi mabdelouahab,

The implementation for the news added conventions regcall and syscall for linux kernel in 64bits, got the code for conventions uninitialized till the 1º proc comes in 1º place before proto, bad bug here.
So I redone all the changes for if table for conventions initialization, and now it's necessary to exclusively call in the command-line the convention and convention initializer, output format and memory model.

One simple example:
testlinux.7z

UASM command-line:

Code Select Expand


./uasm testlinux.asm -c -Cp -archSSE -mf -elf64 -zf4 -W3 -Gy

-c         = Assemble without linking (always set)
-Cp      = Set OPTION CASEMAP none
-archSSE = Set OPTION ARCH (always set)(unnecessary)
-mf       = Set memory model flat
-elf64   = Elf64 Output Format
-W3     = Warning Level
-zf4      = convention initializer 64 bits SystemV style
-Gy       = Calling Convention SystemV

I will repack as soon as I have time.

Yea, ./build.sh: line 15:  3942 Segmentation fault     ./uasm -c -Cp -archSSE -mf -elf64 -zf4 -W3 -Gy $SrcAsm.asm
This one if add *.asm files after command it cleans the pointer's (resetting everything to null), and seg's fault hitting the proto for uses off null-pointers.
Still figuring why this behavior.

After this weeks still can't find a fix for proto in linux, without break windows also.
From my test's declaring the new call's in proto with no proc /or proto before proc end, the uasm crash's with unknow params or symbol.
Added new option to not create stack frame for stackbase:rbp in linux only.
Example anexed.
