This is handled on server side without a need\n for putting ctime on the wire.\n*) The server currently supports changing mode, time, ownership and\n size of the file.\n*) 9P RFC says \"Either all the changes in wstat request happen, or\n none of them does: if the request succeeds, all changes were made;\n if it fails, none were.\"\n I have not done anything to implement this specifically because I\n don\u0027t see a reason.\n\nSigned-off-by: Sripathi Kodi \u003csripathik@in.ibm.com\u003e\nSigned-off-by: Venkateswararao Jujjuri \u003cjvrao@linux.vnet.ibm.com\u003e\nSigned-off-by: Eric Van Hensbergen \u003cericvh@gmail.com\u003e\n" }, { "commit": "f085312204f384a0277a66c3c48ba8f9edcd58f2", "tree": "33006860cc1cd4338de56ba1a9915ed95082814e", "parents": [ "9ffaf63e34821ea60b2e1c8593f968d73728f82b" ], "author": { "name": "Sripathi Kodi", "email": "sripathik@in.ibm.com", "time": "Mon Jul 12 20:07:23 2010 +0530" }, "committer": { "name": "Eric Van Hensbergen", "email": "ericvh@gmail.com", "time": "Mon Aug 02 14:25:09 2010 -0500" }, "message": "9p: getattr client implementation for 9P2000.L protocol.\n\n SYNOPSIS\n\n size[4] Tgetattr tag[2] fid[4] request_mask[8]\n\n size[4] Rgetattr tag[2] lstat[n]\n\n DESCRIPTION\n\n The getattr transaction inquires about the file identified by fid.\n request_mask is a bit mask that specifies which fields of the\n stat structure is the client interested in.\n\n The reply will contain a machine-independent directory entry,\n laid out as follows:\n\n st_result_mask[8]\n Bit mask that indicates which fields in the stat structure\n have been populated by the server\n\n qid.type[1]\n the type of the file (directory, etc.), represented as a bit\n vector corresponding to the high 8 bits of the file\u0027s mode\n word.\n\n qid.vers[4]\n version number for given path\n\n qid.path[8]\n the file server\u0027s unique identification for the file\n\n st_mode[4]\n Permission and flags\n\n st_uid[4]\n User id of owner\n\n st_gid[4]\n Group ID of owner\n\n st_nlink[8]\n Number of hard links\n\n st_rdev[8]\n Device ID (if special file)\n\n st_size[8]\n Size, in bytes\n\n st_blksize[8]\n Block size for file system IO\n\n st_blocks[8]\n Number of file system blocks allocated\n\n st_atime_sec[8]\n Time of last access, seconds\n\n st_atime_nsec[8]\n Time of last access, nanoseconds\n\n st_mtime_sec[8]\n Time of last modification, seconds\n\n st_mtime_nsec[8]\n Time of last modification, nanoseconds\n\n st_ctime_sec[8]\n Time of last status change, seconds\n\n st_ctime_nsec[8]\n Time of last status change, nanoseconds\n\n st_btime_sec[8]\n Time of creation (birth) of file, seconds\n\n st_btime_nsec[8]\n Time of creation (birth) of file, nanoseconds\n\n st_gen[8]\n Inode generation\n\n st_data_version[8]\n Data version number\n\n request_mask and result_mask bit masks contain the following bits\n #define P9_STATS_MODE 0x00000001ULL\n #define P9_STATS_NLINK 0x00000002ULL\n #define P9_STATS_UID 0x00000004ULL\n #define P9_STATS_GID 0x00000008ULL\n #define P9_STATS_RDEV 0x00000010ULL\n #define P9_STATS_ATIME 0x00000020ULL\n #define P9_STATS_MTIME 0x00000040ULL\n #define P9_STATS_CTIME 0x00000080ULL\n #define P9_STATS_INO 0x00000100ULL\n #define P9_STATS_SIZE 0x00000200ULL\n #define P9_STATS_BLOCKS 0x00000400ULL\n\n #define P9_STATS_BTIME 0x00000800ULL\n #define P9_STATS_GEN 0x00001000ULL\n #define P9_STATS_DATA_VERSION 0x00002000ULL\n\n #define P9_STATS_BASIC 0x000007ffULL\n #define P9_STATS_ALL 0x00003fffULL\n\n This patch implements the client side of getattr implementation for\n 9P2000.L. It introduces a new structure p9_stat_dotl for getting\n Linux stat information along with QID. The data layout is similar to\n stat structure in Linux user space with the following major\n differences:\n\n inode (st_ino) is not part of data. Instead qid is.\n\n device (st_dev) is not part of data because this doesn\u0027t make sense\n on the client.\n\n All time variables are 64 bit wide on the wire. The kernel seems to use\n 32 bit variables for these variables. However, some of the architectures\n have used 64 bit variables and glibc exposes 64 bit variables to user\n space on some architectures. Hence to be on the safer side we have made\n these 64 bit in the protocol. Refer to the comments in\n include/asm-generic/stat.h\n\n There are some additional fields: st_btime_sec, st_btime_nsec, st_gen,\n st_data_version apart from the bitmask, st_result_mask. The bit mask\n is filled by the server to indicate which stat fields have been\n populated by the server. Currently there is no clean way for the\n server to obtain these additional fields, so it sends back just the\n basic fields.\n\nSigned-off-by: Sripathi Kodi \u003csripathik@in.ibm.com\u003e\nSigned-off-by: Eric Van Hensbegren \u003cericvh@gmail.com\u003e\n" }, { "commit": "9ffaf63e34821ea60b2e1c8593f968d73728f82b", "tree": "a2fa40eeb0cc9ae7bb1ac5dfbbd23231746290f8", "parents": [ "69d4b4436b54c1a850d475697fda5ca117b09a5e" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Tue Jun 01 09:26:18 2010 +0000" }, "committer": { "name": "Eric Van Hensbergen", "email": "ericvh@gmail.com", "time": "Mon Aug 02 14:25:08 2010 -0500" }, "message": "fs/9p: Pass the correct user credentials during attach\n\nWe need to make sure we pass the right uid value\nduring attach. dotl is similar to dotu in this regard.\nWithout this mapped security model on dotl doesn\u0027t work\n\nSigned-off-by: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nSigned-off-by: Eric Van Hensbergen \u003cericvh@gmail.com\u003e\n" }, { "commit": "7751bdb3a095ad32dd4fcff3443cf8dd4cb1e748", "tree": "6c7a93a546e34d86e433a1be05e3ebfcc4f77754", "parents": [ "97e8442b0971ea6be9a495b3d03402985cfe5d6a" ], "author": { "name": "Sripathi Kodi", "email": "sripathik@in.ibm.com", "time": "Fri Jun 04 13:41:26 2010 +0000" }, "committer": { "name": "Eric Van Hensbergen", "email": "ericvh@gmail.com", "time": "Mon Aug 02 14:25:07 2010 -0500" }, "message": "9p: readdir implementation for 9p2000.L\n\nThis patch implements the kernel part of readdir() implementation for 9p2000.L\n\n Change from V3: Instead of inode, server now sends qids for each dirent\n\n SYNOPSIS\n\n size[4] Treaddir tag[2] fid[4] offset[8] count[4]\n size[4] Rreaddir tag[2] count[4] data[count]\n\n DESCRIPTION\n\n The readdir request asks the server to read the directory specified by \u0027fid\u0027\n at an offset specified by \u0027offset\u0027 and return as many dirent structures as\n possible that fit into count bytes.

very often, we can\nreasonably make use of a loop involving reading the creds pointer and using\natomic_inc_not_zero() to attempt to increment it if it hasn\u0027t already hit zero.\n\nIf successful, we can safely return the credentials in the knowledge that, even\nif the task we\u0027re accessing has released them, they haven\u0027t gone to the RCU\ncleanup code.\n\nWe then change task_state() in procfs to use get_task_cred() rather than\ncalling get_cred() on the result of __task_cred(), as that suffers from the\nsame problem.\n\nWithout this change, a BUG_ON in __put_cred() or in put_cred_rcu() can be\ntripped when it is noticed that the usage count is not zero as it ought to be,\nfor example:\n\nkernel BUG at kernel/cred.c:168!\ninvalid opcode: 0000 [#1] SMP\nlast sysfs file:

The \"first\" parameter can also be set the same way,\nwith the restriction that it must be set before the journal id is\nassigned.\n\nIn addition, if mount becomes stuck waiting for a reply from\ngfs_controld which never arrives, then it is killable and will abort the\nmount gracefully.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n" }, { "commit": "30116ff6c6d140bc696cc624e6d8e38f018c886e", "tree": "d6a69965d025c9de83ff0611a6c5eda913da0430", "parents": [ "540ad6b62b3a188a53b51cac81d8a60d40e29fbd" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Jun 14 09:58:41 2010 +0100" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu Jul 29 09:36:14 2010 +0100" }, "message": "GFS2: Use nobh_writepage\n\nUse nobh_writepage rather than calling mpage_writepage directly.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\n" }, { "commit": "a6f80fb7b5986fda663d94079d3bba0937a6b6ff", "tree": "b8a44b0ed1560ae3f00f1ff4e342f43b7422bcc3", "parents": [ "6c50e1a49b4377b760ee46f824ed04b17be913e3" ], "author": { "name": "Andre Osterhues", "email": "aosterhues@escrypt.com", "time": "Tue Jul 13 15:59:17 2010 -0500" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jul 28 19:59:24 2010 -0700" }, "message": "ecryptfs: Bugfix for error related to ecryptfs_hash_buckets\n\nThe function ecryptfs_uid_hash wrongly assumes that the\nsecond parameter to hash_long() is the number of hash\nbuckets instead of the number of hash bits.\nThis patch fixes that and renames the variable\necryptfs_hash_buckets to ecryptfs_hash_bits to make it\nclearer.\n\nFixes: CVE-2010-2492\n\nSigned-off-by: Andre Osterhues \u003caosterhues@escrypt.com\u003e\nSigned-off-by: Tyler Hicks \u003ctyhicks@linux.vnet.ibm.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6c50e1a49b4377b760ee46f824ed04b17be913e3", "tree": "5e558bcd8fa3ca0d1a999e4c472d206aa688ec68", "parents": [ "d2a97a4e99ff0ffdccd1fc46f22fb34270ef1e56", "03066f23452ff088ad8e2c8acdf4443043f35b51" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jul 28 11:10:53 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jul 28 11:10:53 2010 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:\n ceph: use complete_all and wake_up_all\n ceph: Correct obvious typo of Kconfig variable \"CRYPTO_AES\"\n ceph: fix dentry lease release\n ceph: fix leak of dentry in ceph_init_dentry() error path\n ceph: fix pg_mapping leak on pg_temp updates\n ceph: fix d_release dop for snapdir, snapped dentries\n ceph: avoid dcache readdir for snapdir\n" }, { "commit": "d2a97a4e99ff0ffdccd1fc46f22fb34270ef1e56", "tree": "f9ac90f438bb3221a6e383e7f1c9c817e95ad44b", "parents": [ "fc0f5ac8fe693d1b05f5a928cc48135d1c8b7f2e" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Wed Jul 28 17:56:23 2010 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jul 28 11:10:03 2010 -0700" }, "message": "GFS2: Use kmalloc when possible for -\u003ereaddir()\n\nIf we don\u0027t need a huge amount of memory in -\u003ereaddir() then\nwe can use kmalloc rather than vmalloc to allocate it.
