[M] Change in libosmocore[master]: Add Emscripten build support and JS callback logging backend
by Timur Davydov 23 Jan '26

23 Jan '26

Attention is currently required from: laforge, neels, pespin. Hello Jenkins Builder, fixeria, neels, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmocore/+/41813?usp=email to look at the new patch set (#20). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: Add Emscripten build support and JS callback logging backend ...................................................................... Add Emscripten build support and JS callback logging backend This change enables building libosmocore for sandboxed, non-POSIX environments, specifically WebAssembly targets produced via the Emscripten toolchain. The broader motivation is to allow partial execution of selected Osmocom components in isolated runtime environments where direct access to hardware and traditional operating system facilities (filesystem, sockets, privileged execution) is not available. One intended use case is running a GSM 2G base station where the radio-facing components are executed inside a web environment, while the remaining Osmocom stack and core network components continue to run unchanged on a conventional backend server. In this model, highly stripped-down variants of osmo-bts and osmo-trx are built as static WebAssembly libraries and executed in the browser, while depending on core libraries such as libosmocore, libosmo-netif, and libosmo-abis. A practical advantage of this approach is that no deployment or privileged setup is required on the radio endpoint side. A user can instantiate a radio endpoint with minimal configuration, while all stateful logic and operational complexity remains centralized on the backend. Multiple such radio endpoints may connect to the same backend core network, effectively forming a single logical network from the core network perspective, independent of the physical location of the radio endpoints. Existing libosmocore build logic and platform assumptions rely on the availability of POSIX APIs and OS services which are not present in WebAssembly runtimes. This currently prevents libosmocore from being built for such targets without targeted, build-time adjustments. This patch introduces the minimal set of changes required to enable such builds, without affecting native platforms. As part of this groundwork, a minimal callback-based logging hook is introduced. When building for Emscripten, this hook allows forwarding log messages to an external environment via a user-provided JavaScript callback. This enables integration with browser-side logging or UI infrastructure without introducing new logging backends or runtime dependencies. For all other build targets, the hook resolves to a no-op implementation and does not alter existing logging behavior. No runtime behavior, protocol semantics, or network interactions are changed by this patch. All modifications are strictly limited to build-time and platform-specific code paths and are only active when targeting Emscripten. Native builds and existing deployment scenarios remain unaffected. This patch is intended as groundwork. Follow-up changes, proposed separately and incrementally, may extend similar support to other Osmocom components such as libosmo-netif, libosmo-abis, osmo-bts, and osmo-trx, while keeping all such changes optional and isolated from native builds.

[…] The build fails due to missing Linux-specific headers/types. First, without any guards: stats_tcp.c:33:10: fatal error: 'linux/tcp.h' file not found #include <linux/tcp.h> If I try to workaround this by guarding the include with `#if defined(__linux__)`, the build still fails because the code below relies on Linux-only types/macros: stats_tcp.c:103:18: error: variable has incomplete type 'struct tcp_info' stats_tcp.c:112:56: error: use of undeclared identifier 'TCP_INFO' So this can’t be fixed just by wrapping the include. We need a generic configure-time feature/header check (e.g. for linux/tcp.h and/or the presence of struct tcp_info / TCP_INFO) and conditionally build/enable the TCP_INFO stats code based on that. I’ll address this in a separate patch.

Agreed. I disabled it only to avoid creating files on the Web side, but since Emscripten provides an IndexedDB-backed filesystem, leaving it enabled and failing at runtime is fine.

[…] about the stub idea: - if I have to add a fake non-abstract yet abstract stub to prevent ABC from doing what it was designed to do, it defies the point of ABC, right? =) Instead I can just remove the @abstractmethod decorator to achieve the same goal. - I can adjust these classes here, but i want to keep other peoples' subclasses that may be out there intact, too. I would like to add the new classmethod in an *optional* way, leaving the transition to the new features up to the implementing classes -- transitions are shown in the subsequent commits. As part of this discussion, I'd also like to mention from the future: In a later patch, we generate SdKey classes by using `type('Xxx',...)` instead of `class Xxx:` According to python docs, they are identical: https://docs.python.org/3/library/functions.html#type "The following two...create identical..." However, it turns out that, as soon as ConfigurableParameter inherits from ABC, the newly created `SdKeyXxx.__module__` member suddenly points to module `abc`, not to `pySim.esim.saip.personalization` where it was actually created, and I have to set the `__module__` member explicitly to make things work again. (I don't really like generating classes very much, we should be generating class *instances* instead, but the choice is again to stay backwards compatible with the existing API) So, in all honesty, my opinion is still that ... well ... that abc serves no purpose and doesn't work, as harsh as it may sound. -- To view, visit https://gerrit.osmocom.org/c/pysim/+/39742?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: pysim Gerrit-Branch: master Gerrit-Change-Id: I6522be4c463e34897ca9bff2309b3706a88b3ce8 Gerrit-Change-Number: 39742 Gerrit-PatchSet: 18 Gerrit-Owner: neels <nhofmeyr(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: dexter <pmaier(a)sysmocom.de> Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: neels <nhofmeyr(a)sysmocom.de> Gerrit-CC: pespin <pespin(a)sysmocom.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Comment-Date: Thu, 22 Jan 2026 23:53:23 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: neels <nhofmeyr(a)sysmocom.de> Comment-In-Reply-To: laforge <laforge(a)osmocom.org> Comment-In-Reply-To: fixeria <vyanitskiy(a)sysmocom.de> Comment-In-Reply-To: pespin <pespin(a)sysmocom.de>
