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call sysfs_register_ns_types with the type and it\u0027s operations\n- sysfs_exit_ns when an individual tag is no longer valid\n\n- Implement mount_ns() which returns the ns of the calling process\n so we can attach it to a sysfs superblock.\n- Implement ktype.namespace() which returns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.

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. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "fac2622bbad4d7e3a32c53e631e018b80ec631dc", "tree": "42e4ad2b38c6d40c86eabaff5efff2b0adeb0b40", "parents": [ "2354dcc7218853a6537ec722be40fde9a11c413b" ], "author": { "name": "Eric W.

The patch uses hooks introduced in the\nprevious patch to handle the getting and setting of security information for\nthe sysfs inodes. As was suggested by Eric Biederman the struct iattr in the\nsysfs_dirent structure has been replaced by a structure which contains the\niattr, secdata and secdata length to allow the changes to persist in the event\nthat the inode representing the sysfs_dirent is evicted. Because sysfs only\nstores this information when a change is made all the optional data is moved\ninto one dynamically allocated field.\n\nThis patch addresses an issue where SELinux was denying virtd access to the PCI\nconfiguration entries in sysfs. The lack of setxattr handlers for sysfs\nrequired that a single label be assigned to all entries in sysfs. Granting virtd\naccess to every entry in sysfs is not an acceptable solution so fine grained\nlabeling of sysfs is required such that individual entries can be labeled\nappropriately.\n\n[sds: Fixed compile-time warnings, coding style, and setting of inode security init flags.]\n\nSigned-off-by: David P.

For most attributes, this doesn\u0027t change the\n\"real\" size of the file i.e. how much can be read from it. However, the\nparameter validation for reading and writing binary attribute files is based\non the inode size and not the size specified in the file\u0027s bin_attribute, so it\ncan be broken by this. For example, if we try using dd to write to such a file:\n\n# pwd\n/sys/bus/pci/devices/0000:08:00.0\n# ls -l config\n-rw-r--r-- 1 root root 4096 Feb 1 17:35 config\n# dd if\u003d/dev/zero of\u003dconfig bs\u003d4 count\u003d1\n1+0 records in\n1+0 records out\n# ls -l config\n-rw-r--r-- 1 root root 0 Feb 1 17:50 config\n# dd if\u003d/dev/zero of\u003dconfig bs\u003d4 count\u003d1 seek\u003d128\ndd: writing `config\u0027: No space left on device\n1+0 records in\n0+0 records out\n\nAlso, after truncation to 0, parameter validation for read and write is\ndisabled. Most bin_attribute read and write methods also validate the size and\noffset, but for some this will allow out-of-range access.

This patch implements active reference and\nmakes the association between kobject and sysfs immediately breakable.\n\nNow each sysfs_dirent has two reference counts - s_count and s_active.\ns_count is a regular reference count which guarantees that the\ncontaining sysfs_dirent is accessible. As long as s_count reference\nis held, all sysfs internal fields in sysfs_dirent are accessible\nincluding s_parent and s_name.\n\nThe newly added s_active is active reference count. This is acquired\nby invoking sysfs_get_active() and it\u0027s the caller\u0027s responsibility to\nensure sysfs_dirent itself is accessible (should be holding s_count\none way or the other). Dereferencing sysfs_dirent to access objects\nout of sysfs proper requires active reference. This includes access\nto the associated kobjects, attributes and ops.\n\nThe active references can be drained and denied by calling\nsysfs_deactivate(). All active sysfs_dirents must be deactivated\nafter deletion but before the default reference is dropped. This\nenables immediate disconnect of sysfs nodes. Once a sysfs_dirent is\ndeleted, it won\u0027t access any entity external to sysfs proper.\n\nBecause attr/bin_attr ops access both the node itself and its parent\nfor kobject, they need to hold active references to both.\nsysfs_get/put_active_two() helpers are provided to help grabbing both\nreferences. Parent\u0027s is acquired first and released last.\n\nUnlike other operations, mmapped area lingers on after mmap() is\nfinished and the module implement implementing it and kobj need to\nstay referenced till all the mapped pages are gone. This is\naccomplished by holding one set of active references to the bin_attr\nand its parent if there have been any mmap during lifetime of an\nopenfile. The references are dropped when the openfile is released.\n\nThis change makes sysfs lifetime rules independent from both kobject\u0027s\nand module\u0027s. It not only fixes several race conditions caused by\nsysfs not holding onto the proper module when referencing kobject, but\nalso helps fixing and simplifying lifetime management in driver model\nand drivers by taking sysfs out of the equation.\n\nPlease read the following message for more info.\n\n http://article.gmane.org/gmane.linux.kernel/510293\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "3e5190380ebef77f2b015c9e7a4ca225a3d75021", "tree": "08d17cd0562acf5101063e93c649f5f71f80b3b9", "parents": [ "0c096b507f15397da890051ee73de4266d3941fb" ], "author": { "name": "Tejun Heo", "email": "htejun@gmail.com", "time": "Thu Jun 14 03:45:15 2007 +0900" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Jul 11 16:09:04 2007 -0700" }, "message": "sysfs: make sysfs_dirent-\u003es_element a union\n\nMake sd-\u003es_element a union of sysfs_elem_{dir|symlink|attr|bin_attr}\nand rename it to s_elem.
