QUESTION
I see here that the swig interface file has identical declarations at 2 places (in and after %{ }% part).
...ANSWER
Answered 2022-Mar-14 at 05:50The code between %{ and %} is directly injected in the generated SWIG wrapper code to make the declarations available to the compiler. For example you could have a utility function in this block that's only visible to the compiler but not exposed to the target language, or add #include statements needed to compile the wrapper.
Code outside that block is parsed by SWIG and exposed to the target language. If you left out one of the declarations in this section it wouldn't be exposed to the target language.
You can eliminate the redundancy in this case by using %inline, which both injects the code into the wrapper and parses it for exposure to the target language:
QUESTION
I have a lib, that uses some C on linux. On windows it is just a dummy noop lib with functions that do nothing.
The lib is in 3 files: lib_linux.go, lib_win.go and lib.c
But when I try to compile it on windows, it throws this error: C source files not allowed when not using cgo or SWIG: lib.c
How can I tell to the go compiler to ignore the C source files on windows?
...ANSWER
Answered 2022-Feb-28 at 07:49A similar issue suggests (when tailored to your case):
workarounds
- Rename the
.cfile lib_linux.c;- Or add a build constraint
// +build linuxcondition to the top of the.cfile (conditional compilation).
QUESTION
I need to compile gem5 with the environment inside docker. This is not frequent, and once the compilation is done, I don't need the docker environment anymore. I have a docker image named gerrie/gem5. I want to perform the following process.
Use this image to create a container, mount the local gem5 source code, compile and generate an executable file(Executables are by default in the build directory.), exit the container and delete it. And I want to be able to see the compilation process so that if the code goes wrong, I can fix it.
But I ran into some problems.
docker run -it --rm -v ${HOST_GEM5}:${DOCKER_GEM5} gerrie/gem5 bash -c "scons build/X86/gem5.opt"
When I execute the above command, I will go to the docker terminal. Then the command to compile gem5(scons build/X86/gem5.opt) is not executed. I think it might be because of the -it option. When I remove this option, I don't see any output anymore.
I replaced the command with the following sentence.
docker run -it --rm -v ${HOST_GEM5}:${DOCKER_GEM5} gerrie/gem5 bash -c "echo 'hello'"But I still don't see any output.When I went into the docker container and tried to compile it myself, the build directory was generated. I found that outside docker, I can't delete it.
What should I do? Thanks!

QUESTION
With regard to the Log4j JNDI remote code execution vulnerability that has been identified CVE-2021-44228 - (also see references) - I wondered if Log4j-v1.2 is also impacted, but the closest I got from source code review is the JMS-Appender.
The question is, while the posts on the Internet indicate that Log4j 1.2 is also vulnerable, I am not able to find the relevant source code for it.
Am I missing something that others have identified?
Log4j 1.2 appears to have a vulnerability in the socket-server class, but my understanding is that it needs to be enabled in the first place for it to be applicable and hence is not a passive threat unlike the JNDI-lookup vulnerability which the one identified appears to be.
Is my understanding - that Log4j v1.2 - is not vulnerable to the jndi-remote-code execution bug correct?
ReferencesThis blog post from Cloudflare also indicates the same point as from AKX....that it was introduced from Log4j 2!
Update #1 - A fork of the (now-retired) apache-log4j-1.2.x with patch fixes for few vulnerabilities identified in the older library is now available (from the original log4j author). The site is https://reload4j.qos.ch/. As of 21-Jan-2022 version 1.2.18.2 has been released. Vulnerabilities addressed to date include those pertaining to JMSAppender, SocketServer and Chainsaw vulnerabilities. Note that I am simply relaying this information. Have not verified the fixes from my end. Please refer the link for additional details.
...ANSWER
Answered 2022-Jan-01 at 18:43The JNDI feature was added into Log4j 2.0-beta9.
Log4j 1.x thus does not have the vulnerable code.
QUESTION
I try to test swig library 'std_vector.i', but I can't create a vector in Python3 like official demo, Here is some information.
swig_test.i
...ANSWER
Answered 2022-Jan-22 at 19:25The problem here is how you're importing and using the module you've built.
When you ran SWIG as well as generating some C++ code it also generated some Python too. Rather than directly access the native module you want to access it via the generated python instead, e.g.
QUESTION
REF: https://portswigger.net/daily-swig/ip-spoofing-bug-leaves-django-rest-applications-open-to-ddos-password-cracking-attacks Reported Date: Jan 11 2022
- Other than providing captcha, what security measure should be taken?
- Which version of Django and/or Python is affected by IP Spoofing?
ANSWER
Answered 2022-Jan-12 at 22:10I did some research into the link you shared, Django's source and Django REST Framework's source.
Bare-bones Django is not vulnerable to this, since it doesn't uses X-Forwarded-For, and neither is Python.
Virtually all versions of Django REST Framework are vulnerable, since this commit 9 years ago added the HTTP_X_FORWARDED_FOR check: https://github.com/encode/django-rest-framework/blob/d18d32669ac47178f26409f149160dc2c0c5359c/rest_framework/throttling.py#L155
For measures you can take to avoid this, since a patch is not yet available, you could implement your own ratelimitter, and replace get_ident to only use REMOTE_ADDR.
If your Djando REST Framework application is behind a proxy, you might not be vulnerable to this.
QUESTION
I am using swig 4.0.x to wrap a c++ file.
Everything is working fine except I want to change the accessibility of the generated C# classes from public class to internal class.
So far what I have tried is this: In swig interface file
...ANSWER
Answered 2022-Jan-03 at 13:41Okay, so I have figured it out after asking this question on swig github repository. Following answer courtesy to William Fulton:
SWIGTYPE_xxx classes are called Type Wrapper Classes.
You need to use the C type for the typemap that causes the type wrapper class to be generated. For example SWIGTYPE_p_int is wrapping an int *. Hence you'd use:
%typemap(csclassmodifiers) int * "internal class"
The defaults for all generated proxy and type wrapper classes comes from csharp.swg:
%typemap(csclassmodifiers) SWIGTYPE, SWIGTYPE *, SWIGTYPE &, SWIGTYPE &&, SWIGTYPE [], SWIGTYPE (CLASS::*) "public class"
So just override these typemaps to provide your customised code and read the chapter on Typemaps in the documentation.

QUESTION
Honestly I read and re-read a lot of post on this site regarding to the struct theme. But I need your help.
I have C-style structures
...ANSWER
Answered 2021-Dec-30 at 18:33You can write a typemap to append the Time output argument. SWIG generates a proxy for the structure that can be generated as needed via SWIG_NewPointerObj(). Full example below:
DeviceInterface.h (minimal implementation)
QUESTION
Maybe someone know, how to rewrite getVersion to get in Python version and legacyVersion as a result of function instead of passing them as in/out parameters
...ANSWER
Answered 2021-Dec-30 at 16:29You can define your own typemaps to handle the output parameters. In this case, the typemaps treat all uint32_t* parameters as 200-byte output buffers. This is a minimal example without error checking.
