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 may be a\nsecurity issue, though access to such files is often limited to root. In any\ncase, the validation should remain for safety\u0027s sake!)\n\nThis was previously reported in Bugzilla as bug 9867.\n\nsysfs should ignore size changes or else refuse them (by returning -EINVAL).\nThis patch makes it ignore them.\n\nSigned-off-by: Ben Hutchings \u003cbhutchings@solarflare.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "8e24eea728068bbeb6a3c500b848f883a20bf225", "tree": "93e79da649723e2766237505b22725fec395f139", "parents": [ "530b6412786d7f83592c1a8e2445541ed73fca76" ], "author": { "name": "Harvey Harrison", "email": "harvey.harrison@gmail.com", "time": "Wed Apr 30 00:55:09 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:54 2008 -0700" }, "message": "fs: replace remaining __FUNCTION__ occurrences\n\n__FUNCTION__ is gcc-specific, use __func__\n\nSigned-off-by: Harvey Harrison \u003charvey.harrison@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": "e4ad08fe64afca4ef79ecc4c624e6e871688da0d", "tree": "5b8b390b874700041dc0c095e8ba9ac3ed42ea77", "parents": [ "76f1418b485da2707531178e517bbb5cf06b3c76" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Wed Apr 30 00:54:37 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:50 2008 -0700" }, "message": "mm: bdi: add separate writeback accounting capability\n\nAdd a new BDI capability flag: BDI_CAP_NO_ACCT_WB.

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" } ], "next": "eb36165353d0e5ac32b063f555acedcbaf6d3b75" }
