feat(libkernel): deliver guest signals on Linux and keep signal masks per thread

[Zaid-Talib]

What

Guest signal delivery in libkernel on Linux, and per-thread guest signal masks on both platforms. Based on current upstream main (311c049). Five commits; commits 2, 4 and 5 fix defects that adversarial reviews of the commit before each found and confirmed:

1. feat(libkernel): deliver sceKernelRaiseException on Linux

sceKernelRaiseException threw on Linux (NotImplemented), so a title whose garbage collector stops threads with it could not run there. Unity's PS5Util module does this: it installs a SIGUSR1 handler with sceKernelInstallExceptionHandler, raises SIGUSR1 on each thread and reads mc_rsp from the handler's context (see the existing TechnicalDebt entry). shadPS4 records that libkernel's install is a sigaction wrapper (SA_SIGINFO | SA_RESTART) and the raise a pthread_kill; this follows that model.

• The raise sends the host SIGUSR1 to the target thread with pthread_kill. The host handler builds the FreeBSD-layout ucontext the Windows path already uses: general registers, rip, rsp, rflags, cs, ss and the 512-byte FXSAVE area. It calls the guest handler on the target's own stack and writes the registers back. Only the 416 bytes up to XMM15 are written back; the rest of the FXSAVE area holds the kernel's XSAVE frame marker, and overwriting it would make sigreturn drop the upper YMM halves.
• errno is left as the handler leaves it. libthr does the same: handle_signal in lib/libthr/thread/thr_sig.c saves errno after the user handler.
• A raise on another thread blocks the host signal, takes the target's join lock and returns ESRCH once the thread has finished, so a detached thread's pthread_t is never used after the thread exits. PthreadPrivate records the pthread_t at creation and adoption.
• The handler table is lock-free (the host handler reads it). GuestUcontext is alignas(16) like FreeBSD's mcontext_t; its layout and size do not change.

2. fix(libkernel): keep raises off unregistered threads and clamp the handler's MXCSR

Three defects found by an adversarial review of commit 1, each reproduced before the fix:

• A raise right after scePthreadCreate reached the thread before RunThread set currentThread. scePthreadSelf() in the handler then adopted a second handle (1997 of 2000 immediate raises), and could deadlock on glibc's per-thread lock when the signal interrupted pthread_getattr_np (gdb backtrace in the review). The creator now blocks all signals around the std::thread construction, so the child starts with them blocked. RunThread restores the creator's mask once the thread is registered, as libthr does.
• A handler that set reserved MXCSR bits made rt_sigreturn fail with SIGSEGV. The MXCSR the handler leaves is masked with MXCSR_MASK (0xffbf when it reads 0), as FreeBSD's fpusetregs does. This applies on both platforms; Windows also keeps CONTEXT.MxCsr equal to FltSave.MxCsr.
• The no-device pacing sleep of sceAudioOutOutput/sceAudioOutOutputs (sleepUs, since fix(audioout): keep ports without a device in real time boykopovar/AnyPS5#955) returned early when a raise interrupted it. It now sleeps the remaining time, as TimedWait::SleepNanos does.

3. fix(libkernel): keep guest signal masks per thread in FreeBSD's bit layout

sigprocmask kept one process-wide mask, read only its first word, and tested signal n at bit n. FreeBSD's sigset_t keeps signal n at bit n − 1 (_SIG_BIT), so blocking SIGTERM blocked SIGURG instead. A signal raised while blocked was dropped, and sceKernelRaiseException ignored the target's mask.

• The mask is per thread, as libthr's sigprocmask is (it forwards to the kernel's per-thread mask). All 128 bits are kept in PthreadPrivate, a new thread starts with its creator's mask, and SIGKILL, SIGSTOP and SIGTHR cannot be blocked (SIG_CANTMASK, libthr's SIGCANCEL).
• A signal raised while blocked stays pending and is delivered once, when it is unblocked, before sigprocmask returns.
• On Linux the blocked mapped signals and SIGUSR1 are applied to the thread's host mask, which the kernel enforces and which a query reads back. A handler therefore sees its own signal blocked, as on FreeBSD.
• On Windows the thread keeps its pending signals. raise and the CRT dispatcher record a blocked one, a raise on another thread checks the mask while the target is suspended, and sigprocmask delivers what it unblocks.

4. fix(libkernel): block a signal while its handler runs and restore the mask after it

• Signal blocked during its handler: on Windows a handler did not run with its own signal blocked, so a raise during it ran the handler again inside itself. A raise now claims the signal's bit in the target's mask with one atomic fetch_or, while the target is suspended (or is the caller); a second raise finds the bit set and stays pending until the handler returns. The CRT dispatcher blocks the signal it delivers the same way.
• Mask restored after the handler: FreeBSD's sigreturn installs uc_sigmask. The SIGUSR1 handler's context now carries the interrupted mask, and whatever mask the handler leaves there is installed when it returns. On Linux its mapped bits go to the host frame's uc_sigmask; the CRT dispatcher restores the mask the thread had before the handler.
• Ignored signals: a raise of a signal set to SIG_IGN is discarded, as FreeBSD's tdsendsignal does. On Windows, installing SIG_IGN discards the calling thread's pending signal.
• CRT dispatcher on Windows: it no longer adopts the thread it runs on (that leaked a handle per Ctrl+C), and it no longer defers a signal the CRT raises itself, such as abort()'s SIGABRT, which FreeBSD's abort() unblocks first.

5. fix(libkernel): make sigprocmask atomic and redeliver a pending raise in place

• Atomic sigprocmask on Linux: a SIGUSR1 delivered between sigprocmask's store of the new mask and its host update wrote the handler's interrupted mask back over it. The call returned 0, but the change to a mapped signal was lost (about one call in 100000 under constant raises). sigprocmask now blocks the mapped host signals while it reads, changes and stores the mask, and installs the result with one pthread_sigmask, as the console's system call is atomic.
• Atomic sigprocmask on Windows: it claims SIGUSR1's bit for the same span, so a raise in that span stays pending and is delivered when the call returns.
• Redelivery in place (Windows): a raise that arrived during a handler was delivered afterwards through the self-raise path, so the second handler saw libkernel's context instead of the interrupted code, its register changes were dropped, and each such delivery nested another frame. Deliver now runs the pending raise itself, as FreeBSD delivers after sigreturn: with the interrupted context the previous handler left, the mask it claims, and the handler installed at that moment.
• APC claim timing (Windows): the APC path claimed the signal when the raise was queued, while the target could still be running other code, so a stale interrupted mask could be installed later. The APC now claims when it runs.
• TechnicalDebt records that guest setjmp/longjmp do not save the signal mask as FreeBSD's do.

TechnicalDebt: the "throws on Linux" and "does not consult the target thread's signal mask" lines are replaced by what still differs from the console. A new entry records that a SIGINT or SIGTERM sent from outside the process can run the handler on an emulator thread. On Linux, the handler runs wherever the thread was interrupted, emulator code included. On the console, kernel objects are syscalls and libthr defers signals while a thread holds its internal locks; here a host lock held by the interrupted code stays held. Host waits and sleeps resume after the handler, and the calls Linux does not restart return EINTR to the guest.

Tested

• Ubuntu 24.04, GCC 13.3, Release, -DBUILD_TESTING=ON, after each commit: full build, then ctest with lavapipe and ANYPS5_REQUIRE_VULKAN=1: 409 passed, 0 failed. 23 GPU tests skipped themselves because they need host subgroups wider than lavapipe's 8 lanes.
• After rebasing onto c8a2f06, and again onto 311c049: 415 of 416 passed. guest_sce_net aborts, and it aborts the same way with this branch's files reverted to main, so it is broken on main itself (the IPv6 change in fix(net): provide IPv6 unspecified address object boykopovar/AnyPS5#1248 is the likely cause), not by this branch.
• guest_raise_exception, now registered on every platform, covers:
  • the thread states: self, busy, waiting in sceKernelWaitSema, blocked on a host mutex, leaving a wait;
  • a register round trip: r12, r13, xmm8 and MXCSR, including a reserved MXCSR bit;
  • 50 raises right after scePthreadCreate, each checking scePthreadSelf() in the handler;
  • SIGUSR1 blocked on itself and on another thread;
  • the handler's view of the mask, uc_sigmask round-tripping, and a raise inside the handler being deferred;
  • a raise during a handler patching r12 of the interrupted code after the handler returns;
  • two threads toggling a mapped signal for two seconds under constant raises, checking every query (the unfixed sigprocmask fails 4 runs in 5);
  • a finished thread → ESRCH.
• Stress runs of the raise test, all passing: 150/150 serial and 100/100 with 5 in parallel on 4 cores (commit 1); 100/100 serial and 40/40 with 4 in parallel (commit 2); 60/60 serial together with guest_signals (commit 3); 80/80 serial and 32/32 in parallel, each together with guest_signals (commit 4); 40/40 serial with guest_signals and 24/24 in parallel (commit 5).
• guest_signals covers:
  • the bit layout, and pending delivery with coalescing;
  • all four words, and the unblockable signals;
  • an aliased set/oset;
  • inheritance by a created thread, including a signal above 32;
  • handler mask scoping for CRT signals, and SIG_IGN discards.
• Mutation check, all caught. The tests fail when any of these is removed or reverted: the register write-back, the FXSAVE write-back, the r13 read, the startup signal block, the MXCSR clamp, the bit layout, the host-mask update, the unblockable-signal filter, the creator-mask copy, the mask restore after a CRT handler, the SIG_IGN discard, or the uc_sigmask fill and write-back.
• Windows: not run (no Windows host here). Every changed file compiles with x86_64-w64-mingw32-g++ (GCC 13, -fsyntax-only -Wall -Wextra); Thread.cpp hits the same three errors on main, from that toolchain's older headers (SetThreadDescription, EfficiencyClass). The Windows logic was reviewed by reading only. CI runs it.
• No title tested.

Checklist

• Based on current main; no other open PR implements the same functions. I checked every open PR's diff:
  • fix(libkernel): stop losing and deadlocking sceKernelRaiseException deliveries on Windows boykopovar/AnyPS5#1421 changes the Windows raise path in the same function; it fixes a different issue, and its key ordering (read the thread context before waitCount) is also done here. Whichever lands second needs a small merge.
  • chore: adopt clang-format and pre-commit boykopovar/AnyPS5#1128 (clang-format), feat(libkernel): implement thread cancellation boykopovar/AnyPS5#1141 (thread cancellation) and perf(libSceAudioOut): eliminate per-frame allocations and cache AudioCVT boykopovar/AnyPS5#1174 (AudioOut allocations) touch some of the same files for unrelated changes.
• One topic per PR; follow-ups go in a new PR
• No comments in code except technical debt
• Unimplemented paths throw (NotImplemented_nid_no_patch); silent stubs are listed in TechnicalDebt
• No notes, investigation .md files or images added to the repository (attach them to this PR)
• New third-party code is a submodule built from source
• Generic behaviour, not specific to one title
• Depends on: none
• AI-assisted: yes
