This allows security\nmodules to permit access to reading process state without granting\nfull ptrace access. The base DAC/capability checking remains unchanged.\n\nRead access to /proc/pid/mem continues to apply a full ptrace attach\ncheck since check_mem_permission() already requires the current task\nto already be ptracing the target. The other ptrace checks within\nproc for elements like environ, maps, and fds are changed to pass the\nread mode instead of attach.\n\nIn the SELinux case, we model such reading of process state as a\nreading of a proc file labeled with the target process\u0027 label. This\nenables SELinux policy to permit such reading of process state without\npermitting control or manipulation of the target process, as there are\na number of cases where programs probe for such information via proc\nbut do not need to be able to control the target (e.g. procps,\nlsof, PolicyKit, ConsoleKit). At present we have to choose between\nallowing full ptrace in policy (more permissive than required/desired)\nor breaking functionality (or in some cases just silencing the denials\nvia dontaudit rules but this can hide genuine attacks).\n\nThis version of the patch incorporates comments from Casey Schaufler\n(change/replace existing ptrace_may_attach interface, pass access\nmode), and Chris Wright (provide greater consistency in the checking).\n\nNote that like their predecessors __ptrace_may_attach and\nptrace_may_attach, the __ptrace_may_access and ptrace_may_access\ninterfaces use different return value conventions from each other (0\nor -errno vs. 1 or 0). I retained this difference to avoid any\nchanges to the caller logic but made the difference clearer by\nchanging the latter interface to return a bool rather than an int and\nby adding a comment about it to ptrace.h for any future callers.\n\nSigned-off-by: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nAcked-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\n" }, { "commit": "6924d1ab8b7bbe5ab416713f5701b3316b2df85b", "tree": "affbf0ff13f7522336f25505e8e7b5f12a34e705", "parents": [ "4e78c91abe1a40b905611100a593be62784ba355", "25556c1699ad84dd6077adf67c92eba362aa7dc2", "b764a15f679942a7bc9d4f9645299e1defcc5b43", "437a0a54eea7b101e8a5b70688009956f6522ed0", "41b3eae669fb1ef6ae4acaa937b4e4617a1aa078", "84e65b0a84a2c856bef36f13d122047678408b0a", "684eb0163a98bc329193b4aa4535cdd705a5dd58", "93022136fff9e6130aa128a5ed8a599e93ac813c", "5cb04df8d3f03e37a19f2502591a84156be71772", "44974c8fc1d7047abe414562e0782320f4c1f511", "48cf937f48f68bd1e61f37c6357dbff5adb95532", "205f93288093df69f9ab5f6981aef27b91088b28", "c54f9da1c8ceee19436430afac0798a989eb886d", "0ed368c71aa65cba8d349432bd4dab4a9a2eb39c", "b478458aeebfc55fe409abec43794ac72a623c79", "2d144e63098be47c21ad59d68a4fd17bd73a3aaf", "607baf1f4ef94637ab0f7d0e258932851dc5c0a2", "33af9039cbf629041da2bfa0cf451208391a1ec3", "3557b18fcbe0e29706214f3c7cc680a7823605eb", "63687a528c39a67c1a213cdffa09feb0e6af9dbe", "009b9fc98ddd83f9139fdabb12c0d7a8535d5421", "f6477cc76c73833a56e97f1fafc36a7ca92927e5", "e6b0edef3453677b13e175a104a83eb36d062dd3", "400d34944c4ad82a817c06e570bc93b1114aa596" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Jul 08 09:16:56 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Jul 08 09:16:56 2008 +0200" }, "message": "Merge branches \u0027x86/numa-fixes\u0027, \u0027x86/apic\u0027, \u0027x86/apm\u0027, \u0027x86/bitops\u0027, \u0027x86/build\u0027, \u0027x86/cleanups\u0027, \u0027x86/cpa\u0027, \u0027x86/cpu\u0027, \u0027x86/defconfig\u0027, \u0027x86/gart\u0027, \u0027x86/i8259\u0027, \u0027x86/intel\u0027, \u0027x86/irqstats\u0027, \u0027x86/kconfig\u0027, \u0027x86/ldt\u0027, \u0027x86/mce\u0027, \u0027x86/memtest\u0027, \u0027x86/pat\u0027, \u0027x86/ptemask\u0027, \u0027x86/resumetrace\u0027, \u0027x86/threadinfo\u0027, \u0027x86/timers\u0027, \u0027x86/vdso\u0027 and \u0027x86/xen\u0027 into x86/devel\n" }, { "commit": "ce0c0e50f94e8c55b00a722e8c6e8d6c802be211", "tree": "cd8917c9f7917c75d2c65f2eaa2e4d4c60794bef", "parents": [ "1b40a895df6c7d5a80e71f65674060b03d84bbef" ], "author": { "name": "Andi Kleen", "email": "andi@firstfloor.org", "time": "Fri May 02 11:46:49 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Jul 08 08:11:45 2008 +0200" }, "message": "x86, generic: CPA add statistics about state of direct mapping v4\n\nAdd information about the mapping state of the direct mapping to\n/proc/meminfo.

On the other hand, hiding them completely from the container\u0027s tasks\nsometimes causes user-space to stop working.\n\nWhen developing net sysctl, the common practice was to duplicate a table and\ndrop the write bits in table-\u003emode, but this approach was not very elegant,\nlead to excessive memory consumption and was not suitable in general.\n\nHere\u0027s the alternative solution. To facilitate the per-container sysctls\nctl_table_root-s were introduced. Each root contains a list of\nctl_table_header-s that are visible to different namespaces. The idea of this\nset is to add the permissions() callback on the ctl_table_root to allow ctl\nroot limit permissions to the same ctl_table-s.\n\nThe main user of this functionality is the net-namespaces code, but later this\nwill (should) be used by more and more namespaces, containers and control\ngroups.\n\nActually, this idea\u0027s core is in a single hunk in the third patch. First two\npatches are cleanups for sysctl code, while the third one mostly extends the\narguments set of some sysctl functions.\n\nThis patch:\n\nThese -\u003eread and -\u003ewrite callbacks act in a very similar way, so merge these\npaths to reduce the number of places to patch later and shrink the .text size\n(a bit).\n\nSigned-off-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nAcked-by: \"David S.

The original OOPS is described in the\ncommit 2d3a4e3666325a9709cc8ea2e88151394e8f20fc:\n\n Typical PDE creation code looks like:\n\n \tpde \u003d create_proc_entry(\"foo\", 0, NULL);\n \tif (pde)\n \t\tpde-\u003eproc_fops \u003d \u0026foo_proc_fops;\n\n Notice that PDE is first created, only then -\u003eproc_fops is set up to\n final value. This is a problem because right after creation\n a) PDE is fully visible in /proc , and\n b) -\u003eproc_fops are proc_file_operations which do not have -\u003eopen callback. So, it\u0027s\n possible to -\u003eread without -\u003eopen (see one class of oopses below).\n\n The fix is new API called proc_create() which makes sure -\u003eproc_fops are\n set up before gluing PDE to main tree. Typical new code looks like:\n\n \tpde \u003d proc_create(\"foo\", 0, NULL, \u0026foo_proc_fops);\n \tif (!pde)\n \t\treturn -ENOMEM;\n\n Fix most networking users for a start.\n\n In the long run, create_proc_entry() for regular files will go.\n\nIn addition to this, proc_create_data is introduced to fix reading from\nproc without PDE-\u003edata. The race is basically the same as above.\n\ncreate_proc_entries is replaced in the entire kernel code as new method\nis also simply better.\n\nThis patch:\n\nThe problem is the same as for de-\u003eproc_fops. Right now PDE becomes visible\nwithout data set. So, the entry could be looked up without data. This, in\nmost cases, will simply OOPS.\n\nproc_create_data call is created to address this issue. proc_create now\nbecomes a wrapper around it.\n\nSigned-off-by: Denis V.
