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call sysfs_register_ns_types with the type and it\u0027s operations\n- sysfs_exit_ns when an individual tag is no longer valid\n\n- Implement mount_ns() which returns the ns of the calling process\n so we can attach it to a sysfs superblock.\n- Implement ktype.namespace() which returns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": "0f4288ec6fcc1a47d1fa0241ec1c6dacd5a09e96", "tree": "7112809d470a7e6dc55cd68054896beef24bc184", "parents": [ "fac2622bbad4d7e3a32c53e631e018b80ec631dc" ], "author": { "name": "Eric W.

For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing. In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n pointer argument and return an integer, so most filesystems have to change\n very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n normally call simple_set_mnt() to instantiate the vfsmount. This will\n always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n dcache upon superblock destruction rather than shrink_dcache_anon().\n\n This is required because the superblock may now have multiple trees that\n aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n currently called functions assume that the whole tree is rooted at s_root,\n and that anonymous dentries are not the roots of trees which results in\n dentries being left unculled.\n\n However, with the way NFS superblock sharing are currently set to be\n implemented, these assumptions are violated: the root of the filesystem is\n simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n with child trees.\n\n [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "8215534ce7d073423bfa9c17405c43ab7636ca03", "tree": "b53aed1111cf10a7d42ef0695308c4a70b820747", "parents": [ "988d186de5b6966a71a8cc52e6cb4895fd2f7799" ], "author": { "name": "Maneesh Soni", "email": "maneesh@in.ibm.com", "time": "Tue May 31 10:39:52 2005 +0530" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Jun 20 15:15:37 2005 -0700" }, "message": "[PATCH] sysfs-iattr: set inode attributes\n\no Following patch sets the attributes for newly allocated inodes for sysfs\n objects.
