linux-omarchy: CONFIG_ARCH_MMAP_RND_BITS=32 randomly SIGSYS-kills Proton/Wine child processes (Arch uses 28)

[MolluscMonk]

What happened

On a machine that migrated to the linux-omarchy kernel today (migration 1789325478, package linux-omarchy 7.2.5-3), a Proton Experimental process died with SIGSYS the first time Steam ran anything under Proton after the reboot:

PID: 31214 (wine64-preloade)
Signal: 31 (SYS) si_code: SYS_SECCOMP
Command Line: .../Proton - Experimental/files/lib/wine/i386-unix/wine64-preloader .../wine64 '\\?\S:\steamapps\common\Proton - Experimental\files\share\wine/../xalia/xalia.exe'
Stack trace of thread 31214:
#0  0x00006fff52121026 _start (.../wine64-preloader + 0x1026)

It was Proton's xalia.exe helper, spawned via CreateProcess by a Wine process during Steam's post-install script for a game. The child died on the first syscall of _start (arch_prctl(ARCH_SET_FS), syscall 158), before mapping a single library (VmPeak 204 kB). /proc/<pid>/status from the core: NoNewPrivs: 1, Seccomp: 2, Seccomp_filters: 1.

Root cause

linux-omarchy is built with

CONFIG_ARCH_MMAP_RND_BITS=32        # pkgbuilds/linux-omarchy/config.x86_64 in omacom/omarchy-pkgs
CONFIG_ARCH_MMAP_RND_COMPAT_BITS=16

Stock Arch linux 7.2.3.arch1-3 (checked in its linux-headers package) is built with CONFIG_ARCH_MMAP_RND_BITS=28 / COMPAT_BITS=8.

Proton's Wine installs a seccomp filter for Windows-syscall emulation (found byte-for-byte in Proton - Experimental/files/lib/wine/x86_64-unix/ntdll.so, offset 0xa5340). Decoded:

ld   [12]                ; A = instruction_pointer >> 32
jgt  #0x7000  → ALLOW    ; native (unix) code is assumed to live at IP >= 0x7001_0000_0000
ld   [4]                 ; arch
jne  #AUDIT_ARCH_X86_64 → ALLOW
ld   [8]                 ; A = instruction_pointer & 0xffffffff
jlt  #0x7d400000 → TRAP  ; only the 0x7d400000–0x7d402000 trampoline page is allowed below the line
jge  #0x7d402000 → TRAP
ALLOW

With 28 bits of mmap randomization the mmap base is always ≥ ~0x7efb_0000_0000, so native code is always above that line. With 32 bits the base is spread over 16 TiB, down to ~0x6ffb_0000_0000. Every Wine child process inherits the parent's filter across execve, gets a fresh random layout, and if the (static-PIE) wine64-preloader lands below 0x7001_0000_0000 its first syscall is SECCOMP_RET_TRAP-ed. No SIGSYS handler exists yet in a just-exec'd process, so it is killed. In this core the preloader was mapped at 0x6fff52120000.

Proton has a mitigation for this ("Native libs are being loaded in low addresses … not installing seccomp"), but it only protects the process that installs the filter, not children that inherit it — so on this kernel every Wine process spawn is a dice roll.

Measured on the running 7.2.5-3-omarchy kernel: 3000 process starts, native-library load addresses span exactly 16.0 TiB (min 0x6ffc19815000), and 5 of 3000 (0.17 %) fell below Proton's line. A Proton game launch spawns dozens of Wine processes (wineboot, services, explorer, xalia, launchers, the game itself), so this shows up as occasional helper crashes, games that silently fail to start, or lost launcher/anti-cheat processes. Eleven Proton sessions on the stock kernel over the previous week logged no such crash; the first session on the Omarchy kernel did.

Expected

Proton/Wine processes should not be randomly killed by the kernel's ASLR layout. Either build linux-omarchy with Arch's CONFIG_ARCH_MMAP_RND_BITS=28, or ship a sysctl (vm.mmap_rnd_bits = 28) alongside the kernel. (Upstream Proton's filter is fragile too, but the divergence from Arch is what triggers it, and Omarchy ships Steam.)

Steps to reproduce

1. Boot linux-omarchy (uname -r → 7.2.5-3-omarchy); sudo sysctl vm.mmap_rnd_bits → 32.
2. Launch Proton games repeatedly; watch coredumpctl list for wine64-preloader / SIGSYS.
3. Or measure directly (no Steam needed): sample /proc/self/maps of a few thousand short-lived processes and count how often the highest ld-linux mapping is below 0x700100000000 — ~0.17 % here, 0 % with vm.mmap_rnd_bits=28.

Workaround confirmed by the address math (not yet field-tested): sudo sysctl -w vm.mmap_rnd_bits=28 (persist in /etc/sysctl.d/), or boot the stock linux kernel.

Second confirmed occurrence, same kernel, different trigger — this isn't specific to Proton's xalia.exe helper.

Command line: wine64-preloader .../GE-Proton10-29/files/bin/wine64 'C:\windows\system32\cmd.exe' /c — a CreateProcess("cmd.exe", "/c") helper spawned by the EVE Online launcher (ProtonFixes had just run for app 8500), not xalia.exe.

_start mapped at 0x00006ffdf1da9000, below the 0x7001_0000_0000 line the ntdll seccomp filter uses to allow native code — same threshold identified above. No local vm.mmap_rnd_bits override was present on this machine (default 32-bit randomization from linux-omarchy still in effect), consistent with the reported root cause.

@MolluscMonk @soemuda thank you for the report!

I moved both values to their current defaults. Next release of v7.2.6 should help with these Wine and Proton issues.

For now, please you can apply real time change via the sysctl setting vm.mmap_rnd_bits, per:

$ sudo sysctl -w vm.mmap_rnd_bits=28

@MolluscMonk @soemuda follow-up here.

Can you try the following release candidate kernel for me?

• https://drive.google.com/drive/folders/174fObr4GJLUeESK_Sg2gwHvuRKy9B8eb?usp=drive_link

Use whichever version you prefer from there - bore or BASE.

If you then collect as much system logs as possible, including dmesg complete output before and/or after any possible issue.

Make sure to revert the sysctl setting, if you have it set to be applied on start up.

Thank you!
