2010-08-03can-raw: Fix skb_orphan_try handlingOliver Hartkopp
Commit fc6055a5ba31e2c14e36e8939f9bf2b6d586a7f5 (net: Introduce skb_orphan_try()) allows an early orphan of the skb and takes care on tx timestamping, which needs the sk-reference in the skb on driver level. So does the can-raw socket, which has not been taken into account here. The patch below adds a 'prevent_sk_orphan' bit in the skb tx shared info, which fixes the problem discovered by Matthias Fuchs here: http://marc.info/?t=128030411900003&r=1&w=2 Even if it's not a primary tx timestamp topic it fits well into some skb shared tx context.

This reverts commit 15e83ed78864d0625e87a85f09b297c0919a4797. As explained by Johannes Berg, the optimization made here is invalid. Or, at best, incomplete.

This fid can later be used to set the xattr value. flag value is derived from set Linux setxattr. The manpage says "The flags parameter can be used to refine the semantics of the operation. XATTR_CREATE specifies a pure create, which fails if the named attribute exists already. XATTR_REPLACE specifies a pure replace operation, which fails if the named attribute does not already exist. By default (no flags), the extended attribute will be created if need be, or will simply replace the value if the attribute exists." The actual setxattr operation happens when the fid is clunked. At that point the written byte count and the attr_size specified in TXATTRCREATE should be same otherwise an error will be returned.

The mode argument specifies the permissions to use. New file is created with the uid if the fid and with supplied gid. The flags argument represent Linux access mode flags with which the caller is requesting to open the file with. Protocol allows all the Linux access modes but it is upto the server to allow/disallow any of these acess modes. If the server doesn't support any of the access mode, it is expected to return error.

2010-08-029p: Implement client side of setattr for 9P2000.L protocol.Sripathi Kodi
SYNOPSIS size[4] Tsetattr tag[2] attr[n] size[4] Rsetattr tag[2] DESCRIPTION The setattr command changes some of the file status information. attr resembles the iattr structure used in Linux kernel. It specifies which status parameter is to be changed and to what value. It is laid out as follows: valid[4] specifies which status information is to be changed. Possible values are: ATTR_MODE (1 << 0) ATTR_UID (1 << 1) ATTR_GID (1 << 2) ATTR_SIZE (1 << 3) ATTR_ATIME (1 << 4) ATTR_MTIME (1 << 5) ATTR_ATIME_SET (1 << 7) ATTR_MTIME_SET (1 << 8) The last two bits represent whether the time information is being sent by the client's user space. In the absense of these bits the server always uses server's time. mode[4] File permission bits uid[4] Owner id of file gid[4] Group id of the file size[8] File size atime_sec[8] Time of last file access, seconds atime_nsec[8] Time of last file access, nanoseconds mtime_sec[8] Time of last file modification, seconds mtime_nsec[8] Time of last file modification, nanoseconds Explanation of the patches: -------------------------- *) The kernel just copies relevent contents of iattr structure to p9_iattr_dotl structure and passes it down to the client. The only check it has is calling inode_change_ok() *) The p9_iattr_dotl structure does not have ctime and ia_file parameters because I don't think these are needed in our case. The client user space can request updating just ctime by calling chown(fd, -1, -1). This is handled on server side without a need for putting ctime on the wire. *) The server currently supports changing mode, time, ownership and size of the file. *) 9P RFC says "Either all the changes in wstat request happen, or none of them does: if the request succeeds, all changes were made; if it fails, none were." I have not done anything to implement this specifically because I don't see a reason.

2010-08-029p: getattr client implementation for 9P2000.L protocol.Sripathi Kodi
SYNOPSIS size[4] Tgetattr tag[2] fid[4] request_mask[8] size[4] Rgetattr tag[2] lstat[n] DESCRIPTION The getattr transaction inquires about the file identified by fid. request_mask is a bit mask that specifies which fields of the stat structure is the client interested in. The reply will contain a machine-independent directory entry, laid out as follows: st_result_mask[8] Bit mask that indicates which fields in the stat structure have been populated by the server qid.type[1] the type of the file (directory, etc.), represented as a bit vector corresponding to the high 8 bits of the file's mode word. qid.vers[4] version number for given path qid.path[8] the file server's unique identification for the file st_mode[4] Permission and flags st_uid[4] User id of owner st_gid[4] Group ID of owner st_nlink[8] Number of hard links st_rdev[8] Device ID (if special file) st_size[8] Size, in bytes st_blksize[8] Block size for file system IO st_blocks[8] Number of file system blocks allocated st_atime_sec[8] Time of last access, seconds st_atime_nsec[8] Time of last access, nanoseconds st_mtime_sec[8] Time of last modification, seconds st_mtime_nsec[8] Time of last modification, nanoseconds st_ctime_sec[8] Time of last status change, seconds st_ctime_nsec[8] Time of last status change, nanoseconds st_btime_sec[8] Time of creation (birth) of file, seconds st_btime_nsec[8] Time of creation (birth) of file, nanoseconds st_gen[8] Inode generation st_data_version[8] Data version number request_mask and result_mask bit masks contain the following bits #define P9_STATS_MODE 0x00000001ULL #define P9_STATS_NLINK 0x00000002ULL #define P9_STATS_UID 0x00000004ULL #define P9_STATS_GID 0x00000008ULL #define P9_STATS_RDEV 0x00000010ULL #define P9_STATS_ATIME 0x00000020ULL #define P9_STATS_MTIME 0x00000040ULL #define P9_STATS_CTIME 0x00000080ULL #define P9_STATS_INO 0x00000100ULL #define P9_STATS_SIZE 0x00000200ULL #define P9_STATS_BLOCKS 0x00000400ULL #define P9_STATS_BTIME 0x00000800ULL #define P9_STATS_GEN 0x00001000ULL #define P9_STATS_DATA_VERSION 0x00002000ULL #define P9_STATS_BASIC 0x000007ffULL #define P9_STATS_ALL 0x00003fffULL This patch implements the client side of getattr implementation for 9P2000.L. It introduces a new structure p9_stat_dotl for getting Linux stat information along with QID. The data layout is similar to stat structure in Linux user space with the following major differences: inode (st_ino) is not part of data. Instead qid is. device (st_dev) is not part of data because this doesn't make sense on the client. All time variables are 64 bit wide on the wire. The kernel seems to use 32 bit variables for these variables. However, some of the architectures have used 64 bit variables and glibc exposes 64 bit variables to user space on some architectures. Hence to be on the safer side we have made these 64 bit in the protocol. Refer to the comments in include/asm-generic/stat.h There are some additional fields: st_btime_sec, st_btime_nsec, st_gen, st_data_version apart from the bitmask, st_result_mask. The bit mask is filled by the server to indicate which stat fields have been populated by the server. Currently there is no clean way for the server to obtain these additional fields, so it sends back just the basic fields.

2010-08-029p: readdir implementation for 9p2000.LSripathi Kodi
This patch implements the kernel part of readdir() implementation for 9p2000.L Change from V3: Instead of inode, server now sends qids for each dirent SYNOPSIS size[4] Treaddir tag[2] fid[4] offset[8] count[4] size[4] Rreaddir tag[2] count[4] data[count] DESCRIPTION The readdir request asks the server to read the directory specified by 'fid' at an offset specified by 'offset' and return as many dirent structures as possible that fit into count bytes. Each dirent structure is laid out as follows. qid.type[1] the type of the file (directory, etc.), represented as a bit vector corresponding to the high 8 bits of the file's mode word. qid.vers[4] version number for given path qid.path[8] the file server's unique identification for the file offset[8] offset into the next dirent. type[1] type of this directory entry. name[256] name of this directory entry. This patch adds v9fs_dir_readdir_dotl() as the readdir() call for 9p2000.L. This function sends P9_TREADDIR command to the server. In response the server sends a buffer filled with dirent structures. This is different from the existing v9fs_dir_readdir() call which receives stat structures from the server. This results in significant speedup of readdir() on large directories. For example, doing 'ls >/dev/null' on a directory with 10000 files on my laptop takes 1.088 seconds with the existing code, but only takes 0.339 seconds with the new readdir.

On the bridge TX path we're leaking an skb when br_multicast_rcv returns an error. Reported-by: David Lamparter <equinox@diac24.net> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-07-30tcp: cookie transactions setsockopt memory leakDmitry Popov
There is a bug in do_tcp_setsockopt(net/ipv4/tcp.c), TCP_COOKIE_TRANSACTIONS case. In some cases (when tp->cookie_values == NULL) new tcp_cookie_values structure can be allocated (at cvp), but not bound to tp->cookie_values. So a memory leak occurs.

2010-07-29mac80211: allow drivers to request DTIM periodJohannes Berg
Some features require knowing the DTIM period before associating. This implements the ability to wait for a beacon in mac80211 before assoc to provide this value. It is optional since most likely not all drivers will need this. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-07-28mac80211: inform drivers about the off-channel status on channel changesFelix Fietkau
For some drivers it can be useful to know whether the channel they're supposed to switch to is going to be used for short off-channel work or scanning, or whether the hardware is expected to stay on it for a while longer. This is important for various kinds of calibration work, which takes longer to complete and should keep some persistent state, even if the channel temporarily changes.

2010-07-28Revert "mac80211: fix sw scan bracketing"Luis R. Rodriguez
This reverts this commit. While in theory the change is correct the patch does not address current assumptions made by some drivers, one which is definitley affected is ath9k. Prior to this change the scan complete callback would be called after we returned to the home channel and configured the hardware RX filters. After this change we call the scan complete callback prior to both the hw config and the config filter. At least for ath9k this breaks quite a few assumptions on the callback, leading to disconnects to the AP after every scan making the driver pretty useless on STA mode. The goal behind this commit was to address the now understood spurious warnings from ath9k and mac80211_hwsim on scanning on two wiphys at the same time but we have now supressed these and will address this issue in the next kernel release. When fixing this for good next we must first review the other driver's dependence on this logic and perhaps consider removal of the scan complete callback all together.

2010-07-28bridge: add rcu_read_lock on transmitstephen hemminger
Long ago, when bridge was converted to RCU, rcu lock was equivalent to having preempt disabled. RCU has changed a lot since then and bridge code was still assuming the since transmit was called with bottom half disabled, it was RCU safe.
