The\n only check it has is calling inode_change_ok()\n*) The p9_iattr_dotl structure does not have ctime and ia_file\n parameters because I don\u0027t think these are needed in our case.\n The client user space can request updating just ctime by calling\n chown(fd, -1, -1). 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.

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": "45bc21edb52fa71dbb1324c6f573aa880e95519d", "tree": "adee2b59a562679241f874c978162739e1df78bb", "parents": [ "fae4528b2341f2ab0c86c191e24d9cdd93624c60" ], "author": { "name": "Sripathi Kodi", "email": "sripathik@in.ibm.com", "time": "Mon Mar 08 17:33:04 2010 +0000" }, "committer": { "name": "Eric Van Hensbergen", "email": "ericvh@gmail.com", "time": "Sat Mar 13 08:57:29 2010 -0600" }, "message": "9p: Change the name of new protocol from 9p2010.L to 9p2000.L\n\nThis patch changes the name of the new 9P protocol from 9p2010.L to\n9p2000.u.
