feat(ipc/sem): add semaphore support for dragonOS by mistcoversmyeyes · Pull Request #2172 · DragonOS-Community/DragonOS

mistcoversmyeyes · 2026-08-08T11:14:05Z

Summary

Implement the x86_64 System V semaphore syscalls: semget, semctl, semop, and semtimedop.
Add semaphore-set management to IPC namespaces.
Extract and reuse common System V IPC permission checks.

Scope

Match the Linux 6.6 x86_64 ABI and observable behavior.
SEM_UNDO is out of scope and currently returns ENOSYS.

Acceptance

Valid semaphore syscall requests no longer return ENOSYS.
semop and semtimedop share consistent operation semantics.
Creation, lookup, control, removal, and permission checks match Linux behavior.
Multi-operation requests execute atomically.
Blocking operations wake correctly after value changes or IPC_RMID.
Nonblocking, timeout, signal, invalid-argument, and removed-set errors match Linux behavior.
Concurrent access avoids races, lost wake-ups, use-after-free, and resource leaks.
Existing DragonOS CI tests pass.

Testing

Added 43 System V semaphore dunitests.
QEMU guest test: 43/43 passed.
Format, Clippy, multi-architecture builds, Dunitest, and Integration Test CI passed.

Request changes: this PR establishes a useful base for System V semaphore support, but it does not yet satisfy the Linux 6.6 compatibility and concurrency-safety contract stated in #2142.

The blocking issues are:

IPC_SET permission updates can partially commit on an error, changing the owner even though the syscall returns EINVAL; the shared helper also affects SHM.
SEM_UNDO is rejected with ENOSYS and the new test codifies that incompatibility, while Linux maintains per-process/shared undo state and replays it at process exit.
A single namespace-wide spinlock protects the registry and every semaphore set, so unrelated sets are serialized; the lock also covers allocation-heavy queue simulation and scheduler wakeups.
User-controlled semaphore-set allocation is infallible and can reach the kernel panic allocation handler instead of returning ENOMEM.
SEM_STAT and SEM_STAT_ANY mask their direct table index, causing out-of-range indices to alias valid objects.

The basic syscall wiring, atomic multi-operation simulation, timeout/removal paths, and test breadth are valuable. However, the issues above are architectural or user-visible Linux semantic mismatches rather than optional refinements. Please address them, add the corresponding regression tests, and rerun the guest suite. The current Integration Test check also reports 5666 passed, 1 failed, and 180 skipped; I am not attributing that failure to this PR without further evidence, but the PR description should not claim that Integration Test passed while the check remains red.

+            .iter()
+            .any(|op| (op.sem_flg as u32) & SemFlags::SEM_UNDO.bits() != 0)
+        {
+            return Err(SystemError::ENOSYS);


[P1] Rejecting every SEM_UNDO operation with ENOSYS is not Linux-compatible System V semaphore behavior. Linux 6.6 maintains sem_undo/semadj state, shares the undo list for CLONE_SYSVSEM, clears adjustments on SETVAL/SETALL/IPC_RMID, and replays them from exit_sem() when a task exits. This is essential crash-recovery behavior: without it, a lock holder exiting can leave peers blocked indefinitely. Please implement the full lifecycle before treating #2142 as complete; the new test should verify Linux behavior instead of expecting ENOSYS.

Confirmed. Full SEM_UNDO lifecycle support is required for Linux 6.6 compatibility, including shared undo state for CLONE_SYSVSEM, semadj updates and limits, cleanup on SETVAL/SETALL/IPC_RMID, and replay on task exit. I am implementing this now and will replace the current ENOSYS test with lifecycle coverage. Keeping this thread open until the implementation and tests are complete.

+    /// SysV SHM manager (phase one: per-namespace SHM only)
    pub shm: SpinLock<ShmManager>,
+    /// SysV semaphore manager
+    pub sem: SpinLock<SemManager>,


[P1] A namespace-wide spinlock is too broad for semaphore-set state. Every operation on every set, including update_queue(), is serialized here; queue simulation allocates a HashMap, may rescan waiters quadratically, and calls Waker::wake() while this lock is held. A user can therefore stall unrelated semaphore sets in the same namespace. Please keep the manager lock limited to ID/key/quota lookup, store stable Arc<KernelSemSet> objects with per-set locking, use a non-allocating operation fast path, and collect wakeups for execution after releasing the set lock, following Linux's registry/array locking and wake_q separation.

Please keep the manager lock limited to ID/key/quota lookup, store stable Arc<KernelSemSet> objects with per-set locking, use a non-allocating operation fast path, and collect wakeups for execution after releasing the set lock.

I am currently evaluating the necessity and designing the manager/per-set lock separation. No implementation changes for this lock split have started yet.

I am also coordinating this with the latest semaphore queue work. The design will preserve the unlocked queue-growth preparation and fallible-allocation semantics from b3f637c7, rather than duplicate or replace that work. I will post the finalized scope before touching the locking code so we can avoid overlapping changes.

mistcoversmyeyes · 2026-09-02T16:04:21Z

While reviewing the queue-rescan concern, I found a separate Linux 6.6 compatibility issue in the current unified waiter queue.

Linux classifies queued requests into const operations (the entire operation group has no altering operation) and alter operations when they are enqueued: ipc/sem.c#L2127-L2153. Its update path handles wait-for-zero requests before scanning pending alter requests: ipc/sem.c#L1029-L1039. After a queued alter operation succeeds, Linux immediately checks wait-for-zero requests made satisfiable by that change before continuing with further alter operations: ipc/sem.c#L974-L992.

The current DragonOS implementation stores both classes in one VecDeque, so an older alter waiter can run before an already-satisfied const waiter and make its zero condition false again. This can produce behavior different from Linux.

Proposed minimal design for this PR:

Split the set-level queue into pending_const and pending_alter.
Classify an operation group once: all sem_op == 0 goes to pending_const; any nonzero operation goes to pending_alter.
Process ready const waiters before scanning alter waiters.
After any alter waiter changes semaphore values, return to the const phase before continuing alter processing.
Keep the existing full atomic simulation and weak-FIFO alter scan; defer per-semaphore/simple-complex indexing to a separate performance change.

This fixes the observable ordering difference without attempting to eliminate the irreducible worst-case rescan for complex multi-operation groups.

将等待对象延迟到确认阻塞后创建

当 semop 可立即完成时，这里仍会无条件为 Waker 分配 Arc；带非零超时的 semtimedop 还会额外分配 TimeoutWaker 和 Timer。这使无竞争的信号量快路径以及无效 ID、越界或权限失败等错误路径都承担不必要的堆分配开销；应仅在 simulate_semop 返回 Blocked 且确实需要睡眠后创建这些对象。

There are currently conflicts. Please rebase your code onto the latest origin/master branch and resolve the conflicts correctly according to the intended semantics. Please also review the affected changes and adjust the object abstraction and design as needed to ensure that the changes are merged correctly, rather than resolving the conflicts mechanically.

Pushed three signed-off fixes: 8d1e231 (fallible namespace fs copy), 2c64d68 (unlocked semaphore storage preparation and direct FIFO unlink), and b2717d7 (the CI failure's root cause).

The failing Dunitest run 33979086990 reported a 5000 ms timeout in PtyExecDirectUnameEmitsOutputAndExits although the test took only 9 ms and captured the complete uname output. CollectFdUntilChildExit counted every ready poll as 10 ms. Persistent PTY HUP therefore exhausted an imaginary timeout before the child became waitable. Linux and DragonOS both close files before publishing final exit status; HUP is not proof that waitpid must already succeed. The collector now uses a real monotonic deadline and stops polling a drained, closed output descriptor while continuing bounded waits for process exit. No timeout increase, kernel HUP workaround, or test skip was introduced.

Deterministic pipe and PTY regressions (close output, remain alive for 200 ms, then exit normally) both failed immediately with the old helper on Linux; they pass after the fix. Validation: make kernel, formatting and diff checks pass; QEMU semaphore suite 74/74 and PTY suite 29/29, plus 20 repetitions of each (2,060 passing test executions). Host checks cover allocation failure and the actual queue/table methods; these are structural checks, not guest-wide OOM injection. Three-role adversarial review found no actionable new defect in this delta.

The three new review threads have English replies and are resolved. Earlier unrelated unresolved discussions remain open. Only code and regression tests were pushed. New CI and automated review results are pending.

Pushed signed-off commit dabd730 addressing the two new SEM_UNDO review threads. Existing operations now borrow live debt and commit only affected slots; final-owner replay releases the namespace lock between sets while keeping unprocessed debt visible to semctl. Both threads have detailed English replies and are resolved.

Validation: make kernel and formatting/diff checks pass; the full semaphore dunitest suite passes 76/76 in QEMU plus 20 complete repetitions (1,520 executions). New semantic regressions also pass on the pre-fix guest and Linux host. Actual-source structural checks separately demonstrate removal of the full-size Existing allocation and preservation of pending replay visibility. Three-role adversarial review passed. Only code and tests were pushed; new CI and automated review are pending.

仅在信号量值变化后扫描等待队列

当集合已积累大量阻塞者，而调用者反复执行可立即成功的全零等待或最终值不变的操作时，这里仍会在持有 namespace 级 ipcns.sem 锁期间调用 update_queue()，逐项扫描两个无界等待队列；SEM_UNDO 分支还丢弃了 SemAttempt::Completed 中已有的 values_changed 标志，非 SEM_UNDO 分支也未使用该标志。由于原子操作未改变任何 semval，现有等待者不可能因此变为可执行，应仅在 values_changed 为真时扫描队列，避免普通用户将无效果的成功调用放大为 O(W) 的全局锁内工作。
