When implementing a network namespace I need to be able\nto have multiple network devices with the same name. Currently this\nis a problem for /sys/class/net/*, /sys/devices/virtual/net/*, and\npotentially a few other directories of the form /sys/ ... /net/*.\n\nWhat this patch does is to add an additional tag field to the\nsysfs dirent structure. For directories that should show different\ncontents depending on the context such as /sys/class/net/, and\n/sys/devices/virtual/net/ this tag field is used to specify the\ncontext in which those directories should be visible. Effectively\nthis is the same as creating multiple distinct directories with\nthe same name but internally to sysfs the result is nicer.\n\nI am calling the concept of a single directory that looks like multiple\ndirectories all at the same path in the filesystem tagged directories.\n\nFor the networking namespace the set of directories whose contents I need\nto filter with tags can depend on the presence or absence of hotplug\nhardware or which modules are currently loaded. Which means I need\na simple race free way to setup those directories as tagged.\n\nTo achieve a reace free design all tagged directories are created\nand managed by sysfs itself.\n\nUsers of this interface:\n- define a type in the sysfs_tag_type enumeration.\n- call sysfs_register_ns_types with the type and it\u0027s operations\n- sysfs_exit_ns when an individual tag is no longer valid\n\n- Implement mount_ns() which returns the ns of the calling process\n so we can attach it to a sysfs superblock.\n- Implement ktype.namespace() which returns the ns of a syfs kobject.\n\nEverything else is left up to sysfs and the driver layer.\n\nFor the network namespace mount_ns and namespace() are essentially\none line functions, and look to remain that.\n\nTags are currently represented a const void * pointers as that is\nboth generic, prevides enough information for equality comparisons,\nand is trivial to create for current users, as it is just the\nexisting namespace pointer.\n\nThe work needed in sysfs is more extensive. At each directory\nor symlink creating I need to check if the directory it is being\ncreated in is a tagged directory and if so generate the appropriate\ntag to place on the sysfs_dirent. Likewise at each symlink or\ndirectory removal I need to check if the sysfs directory it is\nbeing removed from is a tagged directory and if so figure out\nwhich tag goes along with the name I am deleting.\n\nCurrently only directories which hold kobjects, and\nsymlinks are supported. There is not enough information\nin the current file attribute interfaces to give us anything\nto discriminate on which makes it useless, and there are\nno potential users which makes it an uninteresting problem\nto solve.\n\nSigned-off-by: Eric W.

The checker only keeps track of the current state; all\nthe state machine logic is kept at the object instance level.\n\nThe checker works by adding a supplementary \"unsigned int astate\" field to the\ndebug_obj structure. It keeps track of the current \"active state\" of the object.\n\nThe only constraints that are imposed on the states by the debugobjects system\nis that:\n\n- activation of an object sets the current active state to 0,\n- deactivation of an object expects the current active state to be 0.\n\nFor the rest of the states, the state mapping is determined by the specific\nobject instance. Therefore, the logic keeping track of the state machine is\nwithin the specialized instance, without any need to know about it at the\ndebugobject level.\n\nThe current object active state is changed by calling:\n\ndebug_object_active_state(addr, descr, expect, next)\n\nwhere \"expect\" is the expected state and \"next\" is the next state to move to if\nthe expected state is found.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7.

The generic\nalgorithm instead merges pairs of equal length lists as early as possible,\nin recursive order. For either algorithm, the elements that extend the\nlist beyond power-of-two length are a special case, handled as nearly as\npossible as a \"rounding-up\" to a full POT.\n\nSome intuition for the locality of reference implications of merge order\nmay be gotten by watching this animation:\n\n http://www.sorting-algorithms.com/merge-sort\n\nSimon\u0027s algorithm requires only O(1) extra space rather than the generic\nalgorithm\u0027s O(log N), but in my non-recursive implementation the actual\nO(log N) data is merely a vector of ~20 pointers, which I\u0027ve put on the\nstack.\n\nLong-running list_sort() calls: If the list passed in may be long, or the\nclient\u0027s cmp() callback function is slow, the client\u0027s cmp() may\nperiodically invoke cond_resched() to voluntarily yield the CPU. All\ninner loops of list_sort() call back to cmp().\n\nStability of the sort: distinct elements that compare equal emerge from\nthe sort in the same order as with Mark\u0027s code, for simple test cases. A\nboot-time test is provided to verify this and other correctness\nrequirements.\n\nA kernel that uses drm.ko appears to run normally with this change; I have\nno suitable hardware to similarly test the use by UBIFS.\n\n[akpm@linux-foundation.org: style tweaks, fix comment, make list_sort_test __init]\nSigned-off-by: Don Mullis \u003cdon.mullis@gmail.com\u003e\nCc: Dave Airlie \u003cairlied@redhat.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Artem Bityutskiy \u003cdedekind@infradead.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d6a2eedfddcded92c8f9b0ac022a99c4134696b0", "tree": "6a0f38fbc74e839fc7712f8ebcb65cce75cdcc06", "parents": [ "a11d2b64e1f2556953120d516241243ea365f0ae" ], "author": { "name": "André Goddard Rosa", "email": "andre.goddard@gmail.com", "time": "Fri Mar 05 13:43:12 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:35 2010 -0800" }, "message": "lib/string.c: simplify strnstr()\n\nSigned-off-by: André Goddard Rosa \u003candre.goddard@gmail.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Joe Perches \u003cjoe@perches.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a11d2b64e1f2556953120d516241243ea365f0ae", "tree": "efb406b16a33fedf9c239fd6c09d8fe74b0042b7", "parents": [ "8a6e25357d51d6ecf4ee21e9048f0416a085a79c" ], "author": { "name": "André Goddard Rosa", "email": "andre.goddard@gmail.com", "time": "Fri Mar 05 13:43:11 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:35 2010 -0800" }, "message": "lib/string.c: simplify stricmp()\n\nRemoves 32 bytes on core2 with gcc 4.4.1:\n text data bss dec hex filename\n 3196 0 0 3196 c7c lib/string-BEFORE.o\n 3164 0 0 3164 c5c lib/string-AFTER.o\n\nSigned-off-by: André Goddard Rosa \u003candre.goddard@gmail.com\u003e\nCc: Joe Perches \u003cjoe@perches.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0347af4ee3922220f6bfe74b87b526aa709a0365", "tree": "6b1f860991e3dae3fc110e02a1a838eb291b94ee", "parents": [ "33fd797b3e2c6a7663b9331150da0acdb31990a2" ], "author": { "name": "Simon Kagstrom", "email": "simon.kagstrom@netinsight.net", "time": "Fri Mar 05 13:42:49 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Mar 06 11:26:32 2010 -0800" }, "message": "lkdtm: add debugfs access and loosen KPROBE ties\n\nAdd adds a debugfs interface and additional failure modes to LKDTM to\nprovide similar functionality to the provoke-crash driver submitted here:\n\n http://lwn.net/Articles/371208/\n\nCrashes can now be induced either through module parameters (as before)\nor through the debugfs interface as in provoke-crash.\n\nThe patch also provides a new \"direct\" interface, where KPROBES are not\nused, i.e., the crash is invoked directly upon write to the debugfs\nfile.
