It\u0027s initialized to the number of tasks which need to stop for\ngroup stop to finish and each stopping or trapping task decrements.\nHowever, each task doesn\u0027t keep track of whether it decremented the\ncounter or not and if woken up before the group stop is complete and\nstops again, it can decrement the counter multiple times.\n\nPlease consider the following example code.\n\n static void *worker(void *arg)\n {\n\t while (1) ;\n\t return NULL;\n }\n\n int main(void)\n {\n\t pthread_t thread;\n\t pid_t pid;\n\t int i;\n\n\t pid \u003d fork();\n\t if (!pid) {\n\t\t for (i \u003d 0; i \u003c 5; i++)\n\t\t\t pthread_create(\u0026thread, NULL, worker, NULL);\n\t\t while (1) ;\n\t\t return 0;\n\t }\n\n\t ptrace(PTRACE_ATTACH, pid, NULL, NULL);\n\t while (1) {\n\t\t waitid(P_PID, pid, NULL, WSTOPPED);\n\t\t ptrace(PTRACE_SINGLESTEP, pid, NULL, (void *)(long)SIGSTOP);\n\t }\n\t return 0;\n }\n\nThe child creates five threads and the parent continuously traps the\nfirst thread and whenever the child gets a signal, SIGSTOP is\ndelivered. If an external process sends SIGSTOP to the child, all\nother threads in the process should reliably stop. However, due to\nthe above bug, the first thread will often end up consuming\ngroup_stop_count multiple times and SIGSTOP often ends up stopping\nnone or part of the other four threads.\n\nThis patch adds a new field task-\u003egroup_stop which is protected by\nsiglock and uses GROUP_STOP_CONSUME flag to track which task is still\nto consume group_stop_count to fix this bug.\n\ntask_clear_group_stop_pending() and task_participate_group_stop() are\nadded to help manipulating group stop states. As ptrace_stop() now\nalso uses task_participate_group_stop(), it will set\nSIGNAL_STOP_STOPPED if it completes a group stop.\n\nThere still are many issues regarding the interaction between group\nstop and ptrace.

At least, nobody even tried since the\noriginal 99d1419d96d7df9cfa56 (\"unshare system call -v5: system call\nhandler function\") was applied more than 4 years ago.\n\nAnd the code is not consistent. unshare_thread() always fails\nunconditionally, while unshare_sighand() and unshare_vm() pretend to work\nif there is nothing to unshare.\n\nRemove unshare_thread(), unshare_sighand(), unshare_vm() helpers and\nrelated variables and add a simple CLONE_THREAD | CLONE_SIGHAND| CLONE_VM\ncheck into check_unshare_flags().\n\nAlso, move the \"CLONE_NEWNS needs CLONE_FS\" check from\ncheck_unshare_flags() to sys_unshare(). This looks more consistent and\nmatches the similar do_sysvsem check in sys_unshare().\n\nNote: with or without this patch \"atomic_read(mm-\u003emm_users) \u003e 1\" can give\na false positive due to get_task_mm().\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nAcked-by: Roland McGrath \u003croland@redhat.com\u003e\nCc: Janak Desai \u003cjanak@us.ibm.com\u003e\nCc: Daniel Lezcano \u003cdaniel.lezcano@free.fr\u003e\nCc: \"Eric W.

This can be solved by adding a smp_wmb between setting the\nfunc and info members and setting setting the cpumask; this will pair\nwith the existing and required smp_rmb ordering the cpumask read before\nthe read of refs. This placement avoids the need a second smp_rmb in\nthe interrupt handler which would be executed on each of the N cpus\nexecuting the call request. (I was thinking this barrier was present\nbut was not).\n\nSecond, the previous write to refs (establishing the zero that we the\ninterrupt handler was testing from all cpus) was performed by a third\nparty cpu. This would invoke transitivity which, as a recient or\nconcurrent addition to memory-barriers.txt now explicitly states, would\nrequire a full smp_mb().\n\nHowever, we know the cpumask will only be set by one cpu (the data\nowner) and any preivous iteration of the mask would have cleared by the\nreading cpu. By redundantly writing refs to 0 on the owning cpu before\nthe smp_wmb, the write to refs will follow the same path as the writes\nthat set the cpumask, which in turn allows us to keep the barrier in the\ninterrupt handler a smp_rmb instead of promoting it to a smp_mb (which\nwill be be executed by N cpus for each of the possible M elements on the\nlist).\n\nI moved and expanded the comment about our (ab)use of the rcu list\nprimitives for the concurrent walk earlier into this function. I\nconsidered moving the first two paragraphs to the queue list head and\nlock, but felt it would have been too disconected from the code.\n\nCc: Paul McKinney \u003cpaulmck@linux.vnet.ibm.com\u003e\nCc: stable@kernel.org (2.6.32 and later)\nSigned-off-by: Milton Miller \u003cmiltonm@bga.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e6cd1e07a185d5f9b0aa75e020df02d3c1c44940", "tree": "74f58672a37de933f8fa3456c0ec19a73b483b65", "parents": [ "ef2b4b95a63a1d23958dcb99eb2c6898eddc87d0" ], "author": { "name": "Milton Miller", "email": "miltonm@bga.com", "time": "Tue Mar 15 13:27:16 2011 -0600" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Mar 17 16:58:10 2011 -0700" }, "message": "call_function_many: fix list delete vs add race\n\nPeter pointed out there was nothing preventing the list_del_rcu in\nsmp_call_function_interrupt from running before the list_add_rcu in\nsmp_call_function_many.\n\nFix this by not setting refs until we have gotten the lock for the list.\nTake advantage of the wmb in list_add_rcu to save an explicit additional\none.\n\nI tried to force this race with a udelay before the lock \u0026 list_add and\nby mixing all 64 online cpus with just 3 random cpus in the mask, but\nwas unsuccessful.

That means we mark the interrupt disabled, but\nleave the hardware unmasked. That\u0027s an optimization because we avoid\nthe hardware access for the common case where no interrupt happens\nafter we marked it disabled. If an interrupt happens, then the\ninterrupt flow handler masks the line at the hardware level and marks\nit pending.\n\nSuspend makes use of this delayed disable as it \"disables\" all\ninterrupts when preparing the suspend transition. Right before the\nsystem goes into hardware suspend state it checks whether one of the\ninterrupts which is marked as a wakeup interrupt came in after\ndisabling it.\n\nMost interrupt chips have a separate register which selects the\ninterrupts which can wake up the system from suspend, so we don\u0027t have\nto mask any on the non wakeup interrupts.\n\nBut now we have to deal with brilliant designed hardware which lacks\nsuch a wakeup configuration facility. For such hardware it\u0027s necessary\nto mask all non wakeup interrupts before going into suspend in order\nto avoid the wakeup from random interrupts.\n\nRather than working around this in the affected interrupt chip\nimplementations we can solve this elegant in the core code itself.\n\nAdd a flag IRQCHIP_MASK_ON_SUSPEND which can be set by the irq chip\nimplementation to indicate, that the interrupts which are not selected\nas wakeup sources must be masked in the suspend path.
