This allows the removal of a truly nasty kludge to make\nsure that mm-\u003enr_ptes was correct in exit_mmap. The underlying problem was\nalways that the stubs, which have ptes, and thus allocated a page table,\nweren\u0027t covered by a VMA.\n\nThis patch fixes that by using install_special_mapping in arch_dup_mmap and\nactivate_context to create the VMA. The stubs have to be moved, since\nshift_arg_pages seems to assume that the stack is the only VMA present at that\npoint during exec, and uses vma_adjust to fiddle its VMA. However, that\nextends the stub VMA by the amount removed from the stack VMA.\n\nTo avoid this problem, the stubs were moved to a different fixed location at\nthe start of the address space.\n\nThe init_stub_pte calls were moved from init_new_context to arch_dup_mmap\nbecause I was occasionally seeing arch_dup_mmap not being called, causing\nexit_mmap to die. Rather than figure out what was really happening, I decided\nit was cleaner to just move the calls so that there\u0027s no doubt that both the\npte and VMA creation happen, no matter what. arch_exit_mmap is used to clear\nthe stub ptes at exit time.\n\nThe STUB_* constants in as-layout.h no longer depend on UM_TASK_SIZE, that\nthat definition is removed, along with the comments complaining about gcc.\n\nBecause the stubs are no longer at the top of the address space, some care is\nneeded while flushing TLBs. update_pte_range checks for addresses in the stub\nrange and skips them. flush_thread now issues two unmaps, one for the range\nbefore STUB_START and one for the range after STUB_END.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "42a2b54ce8c7b9d4f418995a7950e7e2e15e52ce", "tree": "30bcb0ea0a4ee6d5091b1b9a85589cff8b1863fc", "parents": [ "b7c000cbc4f1fa7b82efa95b34f00c2adbeaa3fe" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:31:00 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:29 2008 -0800" }, "message": "uml: clean up TASK_SIZE usage\n\nClean up the calculation and use of the usable address space size on the host.\n\ntask_size is gone, replaced with TASK_SIZE, which is calculated from\nCONFIG_TOP_ADDR. get_kmem_end and set_task_sizes_skas are also gone.\n\nhost_task_size, which refers to the entire address space usable by the UML\nkernel and which may be larger than the address space usable by a UML process,\nsince that has to end on a pgdir boundary, is replaced by CONFIG_TOP_ADDR.\n\nSTACK_TOP is now TASK_SIZE minus the two stub pages.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ca77b555c0aafa3070fbb67592abaaa1b8d31913", "tree": "fb0b42c68879599b65dc897153923ffadca408ab", "parents": [ "655e4ed0c521dcfdbf1c5a79da971560e6733527" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:30:55 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:28 2008 -0800" }, "message": "uml: add virt_to_pte\n\nTurn um_virt_to_phys into virt_to_pte, cleaning up a horrid interface.\n\nIt\u0027s also made non-static and declared in pgtable.h because it\u0027ll be\nneeded when the stubs get a vma.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "655e4ed0c521dcfdbf1c5a79da971560e6733527", "tree": "8b0cf794410c9e632b9ee65b8e0750621d9c96ce", "parents": [ "a5a678c80beac4d163babda243a27eeb9c89bd89" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Mon Feb 04 22:30:55 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Feb 05 09:44:28 2008 -0800" }, "message": "uml: fix page table data sizes\n\nGet the sizes of various pieces of data right when using three-level\npage tables. pgd and pmd entries remain at 32 bits in a 32-bit\ncompilation because page tables will remain in low memory.

It provides infrastructure for more than one parameter,\nand exposes a user mode interface for processes to register pm_qos\nexpectations of processes.\n\nThis interface provides a kernel and user mode interface for registering\nperformance expectations by drivers, subsystems and user space applications on\none of the parameters.\n\nCurrently we have {cpu_dma_latency, network_latency, network_throughput} as\nthe initial set of pm_qos parameters.\n\nThe infrastructure exposes multiple misc device nodes one per implemented\nparameter. The set of parameters implement is defined by pm_qos_power_init()\nand pm_qos_params.h. This is done because having the available parameters\nbeing runtime configurable or changeable from a driver was seen as too easy to\nabuse.\n\nFor each parameter a list of performance requirements is maintained along with\nan aggregated target value. The aggregated target value is updated with\nchanges to the requirement list or elements of the list. Typically the\naggregated target value is simply the max or min of the requirement values\nheld in the parameter list elements.\n\n\u003eFrom kernel mode the use of this interface is simple:\n\npm_qos_add_requirement(param_id, name, target_value):\n\n Will insert a named element in the list for that identified PM_QOS\n parameter with the target value. Upon change to this list the new target is\n recomputed and any registered notifiers are called only if the target value\n is now different.\n\npm_qos_update_requirement(param_id, name, new_target_value):\n\n Will search the list identified by the param_id for the named list element\n and then update its target value, calling the notification tree if the\n aggregated target is changed. with that name is already registered.\n\npm_qos_remove_requirement(param_id, name):\n\n Will search the identified list for the named element and remove it, after\n removal it will update the aggregate target and call the notification tree\n if the target was changed as a result of removing the named requirement.\n\n\u003eFrom user mode:\n\n Only processes can register a pm_qos requirement. To provide for\n automatic cleanup for process the interface requires the process to register\n its parameter requirements in the following way:\n\n To register the default pm_qos target for the specific parameter, the\n process must open one of /dev/[cpu_dma_latency, network_latency,\n network_throughput]\n\n As long as the device node is held open that process has a registered\n requirement on the parameter. The name of the requirement is\n \"process_\u003cPID\u003e\" derived from the current-\u003epid from within the open system\n call.\n\n To change the requested target value the process needs to write a s32\n value to the open device node.

Smack is a kernel based scheme that requires\nan absolute minimum of application support and a very small\namount of configuration data.\n\nSmack uses extended attributes and\nprovides a set of general mount options, borrowing technics used\nelsewhere. Smack uses netlabel for CIPSO labeling. Smack provides\na pseudo-filesystem smackfs that is used for manipulation of\nsystem Smack attributes.\n\nThe patch, patches for ls and sshd, a README, a startup script,\nand x86 binaries for ls and sshd are also available on\n\n http://www.schaufler-ca.com\n\nDevelopment has been done using Fedora Core 7 in a virtual machine\nenvironment and on an old Sony laptop.\n\nSmack provides mandatory access controls based on the label attached\nto a task and the label attached to the object it is attempting to\naccess. Smack labels are deliberately short (1-23 characters) text\nstrings. Single character labels using special characters are reserved\nfor system use. The only operation applied to Smack labels is equality\ncomparison. No wildcards or expressions, regular or otherwise, are\nused. Smack labels are composed of printable characters and may not\ninclude \"/\".\n\nA file always gets the Smack label of the task that created it.\n\nSmack defines and uses these labels:\n\n \"*\" - pronounced \"star\"\n \"_\" - pronounced \"floor\"\n \"^\" - pronounced \"hat\"\n \"?\" - pronounced \"huh\"\n\nThe access rules enforced by Smack are, in order:\n\n1. Any access requested by a task labeled \"*\" is denied.\n2. A read or execute access requested by a task labeled \"^\"\n is permitted.\n3. A read or execute access requested on an object labeled \"_\"\n is permitted.\n4. Any access requested on an object labeled \"*\" is permitted.\n5. Any access requested by a task on an object with the same\n label is permitted.\n6. Any access requested that is explicitly defined in the loaded\n rule set is permitted.\n7. Any other access is denied.\n\nRules may be explicitly defined by writing subject,object,access\ntriples to /smack/load.\n\nSmack rule sets can be easily defined that describe Bell\u0026LaPadula\nsensitivity, Biba integrity, and a variety of interesting\nconfigurations. Smack rule sets can be modified on the fly to\naccommodate changes in the operating environment or even the time\nof day.\n\nSome practical use cases:\n\nHierarchical levels. The less common of the two usual uses\nfor MLS systems is to define hierarchical levels, often\nunclassified, confidential, secret, and so on. To set up smack\nto support this, these rules could be defined:\n\n C Unclass rx\n S C rx\n S Unclass rx\n TS S rx\n TS C rx\n TS Unclass rx\n\nA TS process can read S, C, and Unclass data, but cannot write it.\nAn S process can read C and Unclass. Note that specifying that\nTS can read S and S can read C does not imply TS can read C, it\nhas to be explicitly stated.\n\nNon-hierarchical categories. This is the more common of the\nusual uses for an MLS system. Since the default rule is that a\nsubject cannot access an object with a different label no\naccess rules are required to implement compartmentalization.\n\nA case that the Bell \u0026 LaPadula policy does not allow is demonstrated\nwith this Smack access rule:\n\nA case that Bell\u0026LaPadula does not allow that Smack does:\n\n ESPN ABC r\n ABC ESPN r\n\nOn my portable video device I have two applications, one that\nshows ABC programming and the other ESPN programming. ESPN wants\nto show me sport stories that show up as news, and ABC will\nonly provide minimal information about a sports story if ESPN\nis covering it. Each side can look at the other\u0027s info, neither\ncan change the other. Neither can see what FOX is up to, which\nis just as well all things considered.\n\nAnother case that I especially like:\n\n SatData Guard w\n Guard Publish w\n\nA program running with the Guard label opens a UDP socket and\naccepts messages sent by a program running with a SatData label.\nThe Guard program inspects the message to ensure it is wholesome\nand if it is sends it to a program running with the Publish label.\nThis program then puts the information passed in an appropriate\nplace. Note that the Guard program cannot write to a Publish\nfile system object because file system semanitic require read as\nwell as write.\n\nThe four cases (categories, levels, mutual read, guardbox) here\nare all quite real, and problems I\u0027ve been asked to solve over\nthe years. The first two are easy to do with traditonal MLS systems\nwhile the last two you can\u0027t without invoking privilege, at least\nfor a while.\n\nSigned-off-by: Casey Schaufler \u003ccasey@schaufler-ca.com\u003e\nCc: Joshua Brindle \u003cmethod@manicmethod.com\u003e\nCc: Paul Moore \u003cpaul.moore@hp.com\u003e\nCc: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nCc: Chris Wright \u003cchrisw@sous-sol.org\u003e\nCc: James Morris \u003cjmorris@namei.org\u003e\nCc: \"Ahmed S.

Unfortunately\nthat is not always the case for some filesystems, but it could be an idea\nfor the future.\n\nAlso bring the handling of anonymous page uptodateness in line with that of\nfile backed page management, by marking anon pages as uptodate when they\n_are_ uptodate, rather than when our implementation requires that they be\nmarked as such. Doing allows us to get rid of the smp_wmb\u0027s in the page\ncopying functions, which were especially added for anonymous pages for an\nanalogous memory ordering problem. Both file and anonymous pages are\nhandled with the same barriers.\n\nFAQ:\nQ. Why not do this in flush_dcache_page?\nA. Firstly, flush_dcache_page handles only one side (the smb side) of the\nordering protocol; we\u0027d still need smp_rmb somewhere. Secondly, hiding away\nmemory barriers in a completely unrelated function is nasty; at least in the\nPageUptodate macros, they are located together with (half) the operations\ninvolved in the ordering. Thirdly, the smp_wmb is only required when first\nbringing the page uptodate, wheras flush_dcache_page should be called each time\nit is written to through the kernel mapping. It is logically the wrong place to\nput it.\n\nQ. Why does this increase my text size / reduce my performance / etc.\nA. Because it is adding the necessary instructions to eliminate the data-race.\n\nQ. Can it be improved?\nA. Yes, eg. if you were to create a rule that all SetPageUptodate operations\nrun under the page lock, we could avoid the smp_rmb places where PageUptodate\nis queried under the page lock. Requires audit of all filesystems and at least\nsome would need reworking.

Epoll (efd1) has installed a\n\u003e callback wakeup entry on that queue, and the wake_up() performed by the\n\u003e \"dfd\" net code will end up in ep_poll_callback().
