Conduit Linux Bring-up Report - 2026-06-13

Target server:

  • CS2 container: gp_c2b47a90
  • CS2 server UUID: c2b47a90
  • CS2 name: Test Sunucusu
  • Satisfactory container: gp_d8f13411 (left untouched)

Artifacts copied next to this report:

  • conduit-20260613.log
  • conduit-crash-20260613-113458.txt

Final service state after crash test recovery:

/gp_c2b47a90 running running=true exit=0 oom=false
/gp_d8f13411 exited running=false exit=130 oom=false

Panel DB state after recovery:

   uuid   |      name      | status  |     slug     | port
----------+----------------+---------+--------------+-------

1. Build Result

Final build succeeded using GCC 12 in build/linux-gcc12.

Final link output:

[27/27] Linking CXX shared library package/addons/conduit/bin/conduit.so

Build/deploy issues encountered and fixed:

  • Ubuntu clang++ was 14.0.0 and rejected -std=c++23.
  • hl2sdk headers needed POSIX aliases for stricmp/strcmpi during this Linux build.
  • crash_handler_linux.cpp needed cstdarg visible for va_start/va_end; handled via build flag.
  • watchdog.cpp had a Linux compile error because glibc SIGRTMIN is runtime, not constexpr. Local source change:
-constexpr int kSampleSignal = SIGRTMIN + 4;
+const int kSampleSignal = SIGRTMIN + 4;
  • First deployed build failed to load in Metamod with protobuf ABI mismatch:
[META] Failed to load plugin addons/conduit/bin/conduit: /home/steam/cs2-dedicated/game/csgo/addons/conduit/bin/conduit.so: undefined symbol: _ZNK6google8protobuf7Message11GetTypeNameB5cxx11Ev

Rebuilt with _GLIBCXX_USE_CXX11_ABI=0; Conduit then loaded successfully.

Final configure command used:

cmake -S /root/codex/Conduit -B /root/codex/Conduit/build/linux-gcc12 -G Ninja \
  -DCMAKE_BUILD_TYPE=RelWithDebInfo \
  -DCMAKE_C_COMPILER=gcc-12 \

  "-DCMAKE_CXX_FLAGS=-include strings.h -include cstdarg -Dstricmp=strcasecmp -Dstrcmpi=strcasecmp -D_GLIBCXX_USE_CXX11_ABI=0"

  • Attribution worked.
  • Stack sample landed.
  • Symbol quality is partial: libconduit.so(+0x...) offsets are present, but not function names such as conduit_stall_test.

7. Conduit Log File

Original log file:

/var/lib/gamepanel/servers/c2b47a90/game/csgo/addons/conduit/logs/conduit-20260613.log

Copied artifact:

/root/codex/source-gamepanel/conduit-bringup-artifacts/conduit-20260613.log

Relevant load lines:

2026-06-13 10:33:21 [INFO] gamedata: 1 files loaded: 0 signatures, 0 offsets, all valid
2026-06-13 10:33:21 [INFO] core: Conduit 0.1.0-dev loaded — crash reporter armed, profiler on
2026-06-13 10:33:29 [INFO] core: first GameFrame observed — hook dispatch confirmed

8. Console / Metamod / Signal Warnings

Important console findings:

  1. Before the ABI rebuild, Metamod failed to load Conduit:
[META] Failed to load plugin addons/conduit/bin/conduit: /home/steam/cs2-dedicated/game/csgo/addons/conduit/bin/conduit.so: undefined symbol: _ZNK6google8protobuf7Message11GetTypeNameB5cxx11Ev
[META] Loaded 0 plugins.

This was fixed by rebuilding with _GLIBCXX_USE_CXX11_ABI=0.

  1. After the successful build, no current Metamod load failure was observed. meta list reports Conduit loaded.

  2. Signal/watchdog behavior:

  • No signal clash symptoms observed.
  • No (stack sample timed out) observed.
  • Stack sample appeared, but symbol names are mostly raw offsets for libconduit.so.
  1. Crash test console tail showed the expected deliberate crash:
post-hook: noop
entry.sh: line 192:    36 Segmentation fault      (core dumped) ./cs2 -dedicated -ip 0.0.0.0 -port 27015 -console -usercon -maxplayers 16 +game_type 0 +game_mode 1 +mapgroup mg_active +map de_dust2 +rcon_password changeme +sv_lan 0 +tv_port 27020 -insecure

Other engine/game warnings seen, not clearly Conduit-specific:

Failed loading resource "maps/prefabs/misc/terrorist_team_intro_variant2/world_visibility.vvis_c" (ERROR_FILEOPEN: File not found)
Failed to write backup_round15.txt!
UNEXPECTED LONG FRAME DETECTED

Additional Findings

conduit_dumpbytes found server!CreateInterface:

[Conduit] server!CreateInterface @ 0x7fdfaa682220
  55 48 89 E5 41 55 49 89 F5 41 54 53 48 83 EC 08

But scanning the same pattern failed:

[Conduit] no match in server (285312 bytes scanned)

This looks like a Linux memscan bug or module range issue: export lookup can locate CreateInterface, but ScanPattern does not find the bytes at that address.

conduit_detour_test passed:

[Conduit] detour test: PASS (before=42 during=43 after=42; expected 42/43/42)
