Instead it affects the children\ncreated with fork and clone. The first of these children becomes the init\nprocess of the new pid namespace, the rest become oddball children\nof pid 0. From the point of view of the new pid namespace the process\nthat created it is pid 0, as it\u0027s pid does not map.\n\nA couple of different semantics were considered but this one was\nsettled on because it is easy to implement and it is usable from\npam modules. The core reasons for the existence of unshare.\n\nI took a survey of the callers of pam modules and the following\nappears to be a representative sample of their logic.\n{\n\tsetup stuff include pam\n\tchild \u003d fork();\n\tif (!child) {\n\t\tsetuid()\n exec /bin/bash\n }\n waitpid(child);\n\n pam and other cleanup\n}\n\nAs you can see there is a fork to create the unprivileged user\nspace process. Which means that the unprivileged user space\nprocess will appear as pid 1 in the new pid namespace. Further\nmost login processes do not cope with extraneous children which\nmeans shifting the duty of reaping extraneous child process to\nthe creator of those extraneous children makes the system more\ncomprehensible.\n\nThe practical reason for this set of pid namespace semantics is\nthat it is simple to implement and verify they work correctly.\nWhereas an implementation that requres changing the struct\npid on a process comes with a lot more races and pain. Not\nthe least of which is that glibc caches getpid().\n\nThese semantics are implemented by having two notions\nof the pid namespace of a proces. There is task_active_pid_ns\nwhich is the pid namspace the process was created with\nand the pid namespace that all pids are presented to\nthat process in. The task_active_pid_ns is stored\nin the struct pid of the task.\n\nThere there is the pid namespace that will be used for children\nthat pid namespace is stored in task-\u003ensproxy-\u003epid_ns.\n\nThere is one really nasty corner case in all of this. Which\npid namespace are you in if your parent unshared it\u0027s pid\nnamespace and then on clone you also unshare the pid namespace.\nTo me there are only two possible answers. Either the cases\nis so bizarre and we deny it completely. or the new pid\nnamespace is a descendent of our parent\u0027s active pid namespace,\nand we ignore the task-\u003ensproxy-\u003epid_ns.\n\nTo that end I have modified copy_pid_ns to take both of these\npid namespaces. The active pid namespace and the default\npid namespace of children. Allowing me to simply implement\nunsharing a pid namespace in clone after already unsharing\na pid namespace with unshare.\n\nSigned-off-by: Eric W.

This guarantees that no task\ncan escpae the pid namespace, and that it is safe for proc_flush_task\nto put the proc_mnt of the dead pid_namespace when pid 1 of the\npid namespace calls proc_flush_task.\n\nBefore zap_pid_ns_processes was fixed to wait for all zombies\nin the pid namespace to be reaped the easiest way to generate\na zombie that would escape the pid namespace would be to attach\na debugger to a process inside a pidnamespace from outside the\npid namespace and then exit the pid namespace.\n\nIn the process of trying to fix this bug I have looked at a lot\nof different options and a lot of different directions we can\ngo. There are several limiting factors.\n\n- We need to guarantee that the init process of a pid namespace\n is not reaped before every other task in the pid namespace is\n reaped. Wait succeeding on the init process of a pid namespace\n gives the guarantee that all processes in the pid namespace\n are dead and gone. Or more succinctly it is not possible to\n escape from a pid namespace.\n\n The previous behaviour where some zombies could escape the pid\n namespace violates the assumption made by some reapers of a pid\n namespace init that all of the pid namespace cleanup has completed\n by the time that init is reaped.\n\n- proc_flush_task needs to be called after each task is reaped.\n Tasks are volatile and applications like top and ps frequently\n touch every thread group directory in /proc which triggers dcache\n entries to be created. If we don\u0027t remove those dcache entries\n when tasks are reaped we can get a large build up of useless\n inodes and dentries. Shrink_slab is designed to flush out useful\n cache entries not useless ones so while in the big picture it doesn\u0027t\n hurt if we leak a few if we leak a lot of dentries we put unnatural\n pressure on the kernels memory managment.\n\n I sat down and attempted to measure the cost of calling\n proc_flush_task with lat_tcp (from lmbench) and I get the same\n range of latency readings wether or not proc_flush_task is\n called. Which tells me the runtime cost of the existing\n proc_flush_task is in the noise.\n\n By running find /proc/ \u003e /dev/null with proc_flush_task\n disabled and then examining the counts in the slabcache\n I managed to see us growing about 84 proc_inodes per\n iteration, which is pretty horrific. With proc_flush_task\n enabled I don\u0027t see steady growth in any of the slab caches.\n\n- Mounts of the /proc need a referenece to the pid namespace\n that doesn\u0027t go away until /proc is unmounted. Without\n holding a reference to the pid namespace that lasts until\n a /proc is unmounted it just isn\u0027t safe to lookup and display\n pids in a particular pid_namespace.\n\n- The pid_namespace needs to be able to access proc_mnt until\n the at least the last call of proc_flush_task, for a\n pid_namespace.\n\n Currently there is a the circular reference between proc_mnt\n and the pid_namespace that we break very carefully through\n an interaction of zap_pid_ns_processes, and proc_flush_task.\n That clever interaction going wrong is what caused oopses\n that led us to realize we have a problem.\n\n Even if we fix the pid_namespace and the proc_mnt to have\n conjoined lifetimes and the oopses are fixed we still have\n the problem that zombie processes can escape the pid namespace.\n Which appears to be a problem for people using pid_namespaces\n as inescapable process containers.\n\n- fork/exec/waitpid is a common kernel path and as such we need\n to keep the runtime costs down. Which means as much as possible\n we want to keep from adding code (especially expensive code)\n into the fork/exec/waitpid code path.\n\n Changing zap_pid_ns_processes to fix the problem instead of\n changing the code elsewhere is one of the few solutions I have\n seen that does not increase the cost of the lat_proc test from\n lmbench.\n\nv2: Trivial fixes\n s/threa/thread/\n s/namespac/namespace/\n Add found variable so we only look at task inside rcu_read_lock.\n\nAcked-by: Louis Rilling \u003cLouis.Rilling@kerlabs.com\u003e\nAcked-by: Serge E.

This situation can cause\nthe instance of __rcu_read_unlock() invoked from interrupt to do some\nof the processing that would otherwise have been carried out by the\ntask-level instance of __rcu_read_unlock(). When the interrupt-level\ninstance of __rcu_read_unlock() is called with a scheduler lock held\nfrom interrupt-entry/exit situations where in_irq() returns false,\ndeadlock can result.\n\nThis commit resolves these deadlocks by using negative values of\nthe per-task -\u003ercu_read_lock_nesting counter to indicate that an\ninstance of __rcu_read_unlock() is in flight, which in turn prevents\ninstances from interrupt handlers from doing any special processing.\nThis patch is inspired by Steven Rostedt\u0027s earlier patch that similarly\nmade __rcu_read_unlock() guard against interrupt-mediated recursion\n(see https://lkml.org/lkml/2011/7/15/326), but this commit refines\nSteven\u0027s approach to avoid the need for preemption disabling on the\n__rcu_read_unlock() fastpath and to also avoid the need for manipulating\na separate per-CPU variable.\n\nThis patch avoids need for preempt_disable() by instead using negative\nvalues of the per-task -\u003ercu_read_lock_nesting counter. Note that nested\nrcu_read_lock()/rcu_read_unlock() pairs are still permitted, but they will\nnever see -\u003ercu_read_lock_nesting go to zero, and will therefore never\ninvoke rcu_read_unlock_special(), thus preventing them from seeing the\nRCU_READ_UNLOCK_BLOCKED bit should it be set in -\u003ercu_read_unlock_special.\nThis patch also adds a check for -\u003ercu_read_unlock_special being negative\nin rcu_check_callbacks(), thus preventing the RCU_READ_UNLOCK_NEED_QS\nbit from being set should a scheduling-clock interrupt occur while\n__rcu_read_unlock() is exiting from an outermost RCU read-side critical\nsection.\n\nOf course, __rcu_read_unlock() can be preempted during the time that\n-\u003ercu_read_lock_nesting is negative. This could result in the setting\nof the RCU_READ_UNLOCK_BLOCKED bit after __rcu_read_unlock() checks it,\nand would also result it this task being queued on the corresponding\nrcu_node structure\u0027s blkd_tasks list. Therefore, some later RCU read-side\ncritical section would enter rcu_read_unlock_special() to clean up --\nwhich could result in deadlock if that critical section happened to be in\nthe scheduler where the runqueue or priority-inheritance locks were held.\n\nThis situation is dealt with by making rcu_preempt_note_context_switch()\ncheck for negative -\u003ercu_read_lock_nesting, thus refraining from\nqueuing the task (and from setting RCU_READ_UNLOCK_BLOCKED) if we are\nalready exiting from the outermost RCU read-side critical section (in\nother words, we really are no longer actually in that RCU read-side\ncritical section). In addition, rcu_preempt_note_context_switch()\ninvokes rcu_read_unlock_special() to carry out the cleanup in this case,\nwhich clears out the -\u003ercu_read_unlock_special bits and dequeues the task\n(if necessary), in turn avoiding needless delay of the current RCU grace\nperiod and needless RCU priority boosting.\n\nIt is still illegal to call rcu_read_unlock() while holding a scheduler\nlock if the prior RCU read-side critical section has ever had either\npreemption or irqs enabled. However, the common use case is legal,\nnamely where then entire RCU read-side critical section executes with\nirqs disabled, for example, when the scheduler lock is held across the\nentire lifetime of the RCU read-side critical section.\n\nSigned-off-by: Paul E.

These deadlocks would result from RCU incorrectly\nbelieving that the just-ended RCU read-side critical section had been\npreempted and/or boosted. If that RCU read-side critical section was\nexecuted with either rq or pi locks held, RCU\u0027s ensuing (incorrect)\ncalls to the scheduler would cause the scheduler to attempt to once\nagain acquire the rq and pi locks, resulting in deadlock. More complex\ndeadlock cycles are also possible, involving multiple rq and pi locks\nas well as locks from multiple rcu_node structures.\n\nThis commit fixes synchronization by creating -\u003ercu_boosted field in\ntask_struct that is accessed and modified only when holding the -\u003elock\nin the rcu_node structure on which the task is queued (on that rcu_node\nstructure\u0027s -\u003eblkd_tasks list). This results in tasks accessing only\ntheir own current-\u003ercu_read_unlock_special fields, making unsynchronized\naccess once again legal, and keeping the rcu_read_unlock() fastpath free\nof atomic instructions and memory barriers.\n\nThe reason that the rcu_read_unlock() fastpath does not need to access\nthe new current-\u003ercu_boosted field is that this new field cannot\nbe non-zero unless the RCU_READ_UNLOCK_BLOCKED bit is set in the\ncurrent-\u003ercu_read_unlock_special field. Therefore, rcu_read_unlock()\nneed only test current-\u003ercu_read_unlock_special: if that is zero, then\ncurrent-\u003ercu_boosted must also be zero.\n\nThis bug does not affect TINY_PREEMPT_RCU because this implementation\nof RCU accesses current-\u003ercu_read_unlock_special with irqs disabled,\nthus preventing races on the !SMP systems that TINY_PREEMPT_RCU runs on.\n\nMaybe-reported-by: Dave Jones \u003cdavej@redhat.com\u003e\nMaybe-reported-by: Sergey Senozhatsky \u003csergey.senozhatsky@gmail.com\u003e\nReported-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Paul E.
