Any recommendations for a tool that can generate SBOM for a Kamailio instance based on configured modules? Thanks, Ivan

Hello, I think Olle was looking into that some month ago, maybe (when he reads it) can share some of his research results if possible. You can also find some of his articles e.g., on his linkedin page.

Still digging through this. There are tools that can list your packages if you install Linux packages, i.e. Debian. But there are no tools that can parse your kamailio config to really see what’s loaded and active. It all depends on what you want to do with the SBOM - if you want to check for vulnerabilities, list licenses or have a generic inventory. /O

Hi Olle, Yes, I realised by now that taking enabled Kamailio modules into account when generating SBOM is too much to ask. I'd be ok with obtaining full list of Kamailio dependencies (with transitive dependencies if possible) and then manually filtering them based on module usage. Not sure if at any point during Kamailio build process all sources + dependency sources/binaries are present in the system for scanning/identification? I'm mainly interested in listing (and validating licenses) and having a general inventory. Any recommendations? -- Ivan Ribakov Software Engineer www.zaleos.net On Thu, 28 Sept 2023 at 10:58, Olle E.

I did try a beta of a tool in cyclonedx toolset for scanning C files and it crashed. Will try again, but so far I haven’t succeeded. I suggest we would need one SBOM based on a linux distro, like Debian and one more generic based on C code and the versions of libraries we recommend. I have tried to add pointers to the various third party dependencies in the READMEs over the years in a somewhat unstructured effort, but the information is there. Maybe we can add the dependencies in a way that’s parseable in order to build an SBOM. C code doesn’t have package management like Python, Perl, Go and others so it’s tricky to automate creation of SBOMs. I think that the SBOM tree for the source code and dependencies would grow quite large. Anyway - at this time, I failed. :-) /O

I see, thanks for sharing your experience Olle. I'm no autoconf expert - does anyone know if it's possible to dump more or less concise list of all linked libraries used either during build configuration or the actual build process? I'm thinking that should be pretty close to the source of truth for direct dependencies involved and could act as a starting point for a manual process of figuring out versions and licenses.

Maybe leveraging ldd in a first phase can help building the chain of dependencies: $ ldd src/kamailio linux-vdso.so.1 (0x0000ffff91745000) libm.so.6 => /lib/aarch64-linux-gnu/libm.so.6 (0x0000ffff90f30000) libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000ffff90d80000) /lib/ld-linux-aarch64.so.1 (0x0000ffff9170c000) $ ldd src/modules/tls/tls.so linux-vdso.so.1 (0x0000ffff96e5d000) libssl.so.3 => /lib/aarch64-linux-gnu/libssl.so.3 (0x0000ffff96ca0000) libcrypto.so.3 => /lib/aarch64-linux-gnu/libcrypto.so.3 (0x0000ffff968b0000) libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000ffff96700000) /lib/ld-linux-aarch64.so.1 (0x0000ffff96e24000) $ ldd /lib/aarch64-linux-gnu/libcrypto.so.3 linux-vdso.so.1 (0x0000ffff9952c000) libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000ffff98f50000) /lib/ld-linux-aarch64.so.1 (0x0000ffff994f3000) Might take some time, a matter of what modules are used, but if really needed, the process should be doable manually.

Hi, We are using that "ldd" approach for our Docker containers: We are running ldd on the Kamailio binary and the modules from config (may vary - depending on system) and use that result to create a slim Kamailio Container "from scratch" - without any operating system.

That's a neat trick, Carsten. Thanks for sharing! -- Ivan Ribakov Software Engineer www.zaleos.net On Fri, 29 Sept 2023 at 16:29, Carsten Bock via sr-users < sr-users(a)lists.kamailio.org> wrote:

Hi, We are using that "ldd" approach for our Docker containers: We are running ldd on the Kamailio binary and the modules from config (may vary - depending on system) and use that result to create a slim Kamailio Container "from scratch" - without any operating system.

I'd be ok with obtaining full list of Kamailio dependencies (with transitive dependencies if possible) and then manually filtering them based on module usage. Not sure if at any point during Kamailio build process all sources + dependency sources/binaries are present in the system for scanning/identification? I'm mainly interested in listing (and validating licenses) and having a general inventory. Any recommendations? I did try a beta of a tool in cyclonedx toolset for scanning C files and it crashed. Will try again, but so far I haven’t succeeded. I suggest we would need one SBOM based on a linux distro, like Debian and one more generic based on C code and the versions of libraries we recommend. I have tried to add pointers to the various third party dependencies in the READMEs over the years in a somewhat unstructured effort, but the information is there.
