# 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:
```text
/gp_c2b47a90 running running=true exit=0 oom=false
/gp_d8f13411 exited running=false exit=130 oom=false
```
Panel DB state after recovery:
```text
uuid | name | status | slug | port
----------+----------------+---------+--------------+-------
c2b47a90 | Test Sunucusu | running | cs2 | 27015
d8f13411 | MukemmelSunucu | stopped | satisfactory | 7777
(2 rows)
```
## 1. Build Result
Final build succeeded using GCC 12 in `build/linux-gcc12`.
Final link output:
```text
[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:
```diff
-constexpr int kSampleSignal = SIGRTMIN + 4;
+const int kSampleSignal = SIGRTMIN + 4;
```
- First deployed build failed to load in Metamod with protobuf ABI mismatch:
```text
[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:
```sh
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_COMPILER=g++-12 \
"-DCMAKE_CXX_FLAGS=-include strings.h -include cstdarg -Dstricmp=strcasecmp -Dstrcmpi=strcasecmp -D_GLIBCXX_USE_CXX11_ABI=0"
```

## 4. conduit_schema

--- conduit_schema CBaseEntity m_iTeamNum ---

```
Comparison with Windows reference from the bring-up doc:
- `CCSPlayerPawn::m_iHealth`: Linux `0x5B0`, Windows expected `0x2D0` -> mismatch.
- `CBaseEntity::m_iTeamNum`: Linux `0x624`, Windows expected `0x344` -> mismatch.

```
Notes:
- 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:
```text
/var/lib/gamepanel/servers/c2b47a90/game/csgo/addons/conduit/logs/conduit-20260613.log
```
Copied artifact:
```text
/root/codex/source-gamepanel/conduit-bringup-artifacts/conduit-20260613.log
```
Relevant load lines:
```text
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:
```text
[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`.
2. After the successful build, no current Metamod load failure was observed. `meta list` reports Conduit loaded.
3. 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`.
4. Crash test console tail showed the expected deliberate crash:
```text
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:
```text
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`:
```text
[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:
```text
[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:
```text
[Conduit] detour test: PASS (before=42 during=43 after=42; expected 42/43/42)
```
