QUESTION

Writing and linking shared libraries in assembly 32-bit

Asked 2022-Apr-01 at 11:39

I am currently learning assembler for x86 with att syntax. Over the past time I have already written exercise programs without dependencies. Now I wanted to try writing a shared shared-library, as this is what I do in C most of the time.

I thought it may be a good idea to write a simple "test" program, which consists of an, in asm written, test-library and a program, that links to this test-library.

I assembled the library with: as -32 prog.s -o prog.o
and the caller with: as -32 startprog.s -o startprog.o

After I assembled both files, I ran the linker on the library with ld -melf_i386 -fPIE -shared prog.o -o libprog.so
and on the caller ld -melf_i386 startprog.o -L./ -lprog -o startprog

Up to this point everything worked fine. But then I tried to run the program ./startprog, which causes a Segment violation. I re-ran with gdb and set _start as a breakpoint. As soon as I entered r into gdb, to actually start the execution, I was greeted with the same SIGSEGV. It seems to occur in the libc write() function. At least that is, what I can make of this.

The complete output looks like this:

As stated in the UPDATE, i've got it working by patching the runtime of the ELF with patchelf --set-interpreter /lib/ld-linux.so.2 startprog

Also as stated, if anyone knows, why it automatically assigned the libc as the runtime, I would be pretty thankful, if they would post the answer. It confuses me to no end any I would like to avoid patching the binary every time.

I wonder how patchelf affects elf info.

You don't need to wonder -- you could just see.

Compare the output from readelf -WS libmyib.so before and after, and you will observe that patchelf does affect ELF info (it would be pointless if it didn't).

QUESTION

Azure Pipelines agent running in container throwing error on concurrent builds

Asked 2021-Mar-05 at 17:59

I have three Azure Pipeline agents built on Ubuntu 18.04 images and deployed to a Kubernetes cluster. Agents are running the latest version, 2.182.1, but this problem also happened using 2.181.0.

Executing build pipelines individually works just fine. Build completes successfully every time. But whenever a second pipeline starts while another pipeline is already running, it fails - every time - on the "Checkout" job with the following error:

The working folder U:\azp\agent\_work\1\s is already in use by the workspace ws_1_34;Project Collection Build Service (myaccount) on computer linux-agent-deployment-78bfb76d.

These are three separate and distinct agents running as separate containers. Why would a job from one container be impacting a job running on a different container? Concurrent builds work all day long on my non-container Windows servers.

The container agents are deployed as a standard Kubernetes "deployment" object:

Solution has been found. Here's how I resolved this for anyone coming across this post:

I discovered a helm chart for Azure Pipeline agents - emberstack/docker-azure-pipelines-agent - and after poking around in the contents, discovered what was staring me in the face the last couple of days: "StatefulSets"

Simple, easy to test, and working well so far. I refactored my k8s manifest as a StatefulSet object and the agents are up and able to run builds concurrently. Still more testing to do, but looking very positive at this point.

QUESTION

Any way to add a static library to a dynamic library without rebuilding dynamic library?

Asked 2021-Feb-24 at 03:31

Let's say I have a static library libmystatic.a and a dynamic library libmydynamic.so. Is it possible to use command line tools like ar or patchelf etc to put the libmystatic.a archive into the dynamic library?

So it would be the equivalent of rebuilding libmy_dynamic.so and editing the CMakeLists.txt to add:

...

ANSWER

Answered 2021-Feb-24 at 03:31

Is it possible

No (on most systems). No (on any ELF system).

A fully linked image (such as the executable or a shared library) is considered final -- the linker discards most of the info that you would need to rebuild it.

AIX is a notable exception -- rebuilding certain kinds of shared libraries is possible there.

Implement missing symbol on a shared library

Asked 2020-Dec-17 at 19:09

I have a third-party library (let say libfoobar.so) that depends of another third-party library called libutils.so. I only have the old version of libutils.so, his older version is missing a symbol (exported function) that only exists in the new version.

I can code the function in a new shared library (let say libwrapper.so):

...

ANSWER

Answered 2020-Dec-17 at 19:09

Ok, i solved the problem in a weird way creating a "proxy" library that wraps the functions used.

Step following the previous example:

open libfoobar.so in a hexadecimal editor and patch (change) the linking to a new shared library replacing the string libutils.so by libutilx.so (respect the character count)
also change the SONAME, in this example change LIBSUTILS by LIBUTILX
code the wrapper and compile as libutilx.so. C code example below
put in the same folder with libfoobar.so and DONE.

I just did the following and wasn't able to reproduce your error:

make a new compute instance
open it up using JupyterLab
open a new terminal
conda activate azureml_py36
conda install seaborn -y
open a new notebook and run import seaborn as sns

Are you using the kernel, Python 3.6 - AzureML (i.e. the azureml_py36 conda env)?
Have you tried restarting the kernel and/or creating a new compute instance?
