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": "69d4b4436b54c1a850d475697fda5ca117b09a5e", "tree": "e7f1ad979bacad89bd359938d1211caf27dbe8cf", "parents": [ "7751bdb3a095ad32dd4fcff3443cf8dd4cb1e748" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Tue Jun 01 09:26:17 2010 +0000" }, "committer": { "name": "Eric Van Hensbergen", "email": "ericvh@gmail.com", "time": "Mon Aug 02 14:25:08 2010 -0500" }, "message": "net/9p: Handle the server returned error properly\n\nWe need to get the negative errno value in the kernel\neven for dotl.\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.

In response the server\n sends a buffer filled with dirent structures. This is different from the\n existing v9fs_dir_readdir() call which receives stat structures from the server.\n This results in significant speedup of readdir() on large directories.\n For example, doing \u0027ls \u003e/dev/null\u0027 on a directory with 10000 files on my\n laptop takes 1.088 seconds with the existing code, but only takes 0.339 seconds\n with the new readdir.\n\nSigned-off-by: Sripathi Kodi \u003csripathik@in.ibm.com\u003e\nReviewed-by: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nSigned-off-by: Eric Van Hensbergen \u003cericvh@gmail.com\u003e\n" }, { "commit": "cff6b8a9b81b404e8ce0257b26007c3afe625212", "tree": "8d8793de1843a1831f5ee38efb273a30f06c2a65", "parents": [ "b126468e08d92aaeffa58ef04d70e417241dadc1" ], "author": { "name": "Dan Carpenter", "email": "error27@gmail.com", "time": "Sat Jul 10 11:51:54 2010 +0200" }, "committer": { "name": "Eric Van Hensbergen", "email": "ericvh@gmail.com", "time": "Mon Aug 02 10:37:17 2010 -0500" }, "message": "9p: strlen() doesn\u0027t count the terminator\n\nThis is an off by one bug because strlen() doesn\u0027t count the NULL\nterminator.
