They\n will be privileged with respect to the new namespace, but this should\n only include resources which the unprivileged user already owns.\n\n- Provide separate limits and accounting for userids in different\n namespaces.\n\nStatus:\n\n Currently (as of 2.6.38) you can clone with the CLONE_NEWUSER flag to\n get a new user namespace if you have the CAP_SYS_ADMIN, CAP_SETUID, and\n CAP_SETGID capabilities. What this gets you is a whole new set of\n userids, meaning that user 500 will have a different \u0027struct user\u0027 in\n your namespace than in other namespaces. So any accounting information\n stored in struct user will be unique to your namespace.\n\n However, throughout the kernel there are checks which\n\n - simply check for a capability. Since root in a child namespace\n has all capabilities, this means that a child namespace is not\n constrained.\n\n - simply compare uid1 \u003d\u003d uid2. Since these are the integer uids,\n uid 500 in namespace 1 will be said to be equal to uid 500 in\n namespace 2.\n\n As a result, the lxc implementation at lxc.sf.net does not use user\n namespaces. This is actually helpful because it leaves us free to\n develop user namespaces in such a way that, for some time, user\n namespaces may be unuseful.\n\nBugs aside, this patchset is supposed to not at all affect systems which\nare not actively using user namespaces, and only restrict what tasks in\nchild user namespace can do. They begin to limit privilege to a user\nnamespace, so that root in a container cannot kill or ptrace tasks in the\nparent user namespace, and can only get world access rights to files.\nSince all files currently belong to the initila user namespace, that means\nthat child user namespaces can only get world access rights to *all*\nfiles. While this temporarily makes user namespaces bad for system\ncontainers, it starts to get useful for some sandboxing.\n\nI\u0027ve run the \u0027runltplite.sh\u0027 with and without this patchset and found no\ndifference.\n\nThis patch:\n\ncopy_process() handles CLONE_NEWUSER before the rest of the namespaces.\nSo in the case of clone(CLONE_NEWUSER|CLONE_NEWUTS) the new uts namespace\nwill have the new user namespace as its owner. That is what we want,\nsince we want root in that new userns to be able to have privilege over\nit.\n\nChangelog:\n\tFeb 15: don\u0027t set uts_ns-\u003euser_ns if we didn\u0027t create\n\t\ta new uts_ns.\n\tFeb 23: Move extern init_user_ns declaration from\n\t\tinit/version.c to utsname.h.\n\nSigned-off-by: Serge E.

This blocked the notifier from continuing to\nstart other more critical pieces of cpu bring-up (in our case based on a\n2.6.32 fork, it was the mce). As a result, during soft cpu online/offline\ntesting, the system would panic when a cpu was offlined because the cpu\nnotifier would succeed in processing a watchdog disable cpu event and\nwould panic in the mce case as a result of un-initialized variables from a\nnever executed cpu up event.\n\nI realized the hardlockup/softlockup cases are really just debugging aids\nand should never impede the progress of a cpu up/down event.

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.
