That is inefficient if, for example, the driver has no room for stations any more because then the station will go through the entire auth/assoc handshake, only to be kicked out afterwards. To address this a bit better, at least with drivers using the new station state callback, allow hostapd to add stations in unauthenticated mode, just after receiving the AUTH frame, before even replying. Thus if there's no more space at that point, it can send a negative auth frame back. It still needs to handle later state transition errors though, of course.

It adds the support of (*,*) and (*,G) entries. The user should define an (*,*) entry which is not used for real forwarding. This entry defines the upstream in iif and contains all interfaces from the static tree in its oifs. It will be used to forward packet upstream when they come from an interface belonging to the static tree. Hence, the user should define (*,G) entries to build its static tree. Note that upstream interface must be part of oifs: packets are sent to all oifs interfaces except the input interface. This ensures to always join the whole static tree, even if the packet is not coming from the upstream interface. Signed-off-by: Nicolas Dichtel Acked-by: David L Stevens Signed-off-by: David S.

Currently, there's no way to report per-layer stats. To address the above issues, adding a new DVBv5-based stats API. While here, correct inner code nomenclature on a few places.

Avati" Date: Sun, 19 Aug 2012 08:53:23 -0400 Subject: fuse: implement NFS-like readdirplus support This patch implements readdirplus support in FUSE, similar to NFS. The payload returned in the readdirplus call contains 'fuse_entry_out' structure thereby providing all the necessary inputs for 'faking' a lookup() operation on the spot. If the dentry and inode already existed (for e.g. in a re-run of ls -l) then just the inode attributes timeout and dentry timeout are refreshed. With a simple client->network->server implementation of a FUSE based filesystem, the following performance observations were made: Test: Performing a filesystem crawl over 20,000 files with sh# time ls -lR /mnt Without readdirplus: Run 1: 18.1s Run 2: 16.0s Run 3: 16.2s With readdirplus: Run 1: 4.1s Run 2: 3.8s Run 3: 3.8s The performance improvement is significant as it avoided 20,000 upcalls calls (lookup).

User level applications both in a virtual machine and on the host can use the VM Sockets API, which facilitates fast and efficient communication between guest virtual machines and their host. A socket address family, designed to be compatible with UDP and TCP at the interface level, is provided. Today, VM Sockets is used by various VMware Tools components inside the guest for zero-config, network-less access to VMware host services. In addition to this, VMware's users are using VM Sockets for various applications, where network access of the virtual machine is restricted or non-existent. Examples of this are VMs communicating with device proxies for proprietary hardware running as host applications and automated testing of applications running within virtual machines. The VMware VM Sockets are similar to other socket types, like Berkeley UNIX socket interface. The VM Sockets module supports both connection-oriented stream sockets like TCP, and connectionless datagram sockets like UDP. The VM Sockets protocol family is defined as "AF_VSOCK" and the socket operations split for SOCK_DGRAM and SOCK_STREAM. For additional information about the use of VM Sockets, please refer to the VM Sockets Programming Guide available at: https://www.vmware.com/support/developer/vmci-sdk/ Signed-off-by: George Zhang Signed-off-by: Dmitry Torokhov Signed-off-by: Andy king Signed-off-by: David S.

An example is mmio device base addresses, where KVM must know the base address for a given device to properly emulate mmio accesses within a certain address range or directly map a device with virtualiation extensions into the guest address space.

When this flag is set, the btrfs send code will never write file data into the stream (thus also avoiding expensive reads of that data in the first place). BTRFS_SEND_C_UPDATE_EXTENT commands will be sent (instead of BTRFS_SEND_C_WRITE) with an offset, length pair indicating the extent in question. This patch does not affect the operation of BTRFS_SEND_C_CLONE commands - they will continue to be sent when a search finds an appropriate extent to clone from.

Unfortunately the parses for the Processing Unit Descriptor came with a very subtle bug... Functions uac_processing_unit_iProcessing() and uac_processing_unit_specific() were indexing the baSourceID array forgetting the fields before the iProcessing and process-specific descriptors.

The band-aid works by using bounce buffers to snapshot page contents instead of waiting. For those wondering about the ext3 bandage -- fixing the jbd locking (which was done as part of ext4dev years ago) is a lot of surgery, and setting PG_writeback on data pages when we actually hold the page lock dropped ext3 performance by nearly an order of magnitude. If we're going to migrate iscsi and raid to use stable page writes, the complaints about high latency will likely return. We might as well centralize their page snapshotting thing to one place.

Current mainline implementation of hfsplus file system driver treats as extended attributes only two fields (fdType and fdCreator) of user_info field in file description record (struct hfsplus_cat_file). It is possible to get or set only these two fields as extended attributes. But HFS+ treats as com.apple.FinderInfo extended attribute an union of user_info and finder_info fields as for file (struct hfsplus_cat_file) as for folder (struct hfsplus_cat_folder). Moreover, current mainline implementation of hfsplus file system driver doesn't support special metadata file - attributes tree. Mac OS X 10.4 and later support extended attributes by making use of the HFS+ filesystem Attributes file B*-tree feature which allows for named forks. Mac OS X supports only inline extended attributes, limiting their size to 3802 bytes. Any regular file may have a list of extended attributes. HFS+ supports an arbitrary number of named forks. Each attribute is denoted by a name and the associated data. The name is a null-terminated Unicode string. It is possible to list, to get, to set, and to remove extended attributes from files or directories. It exists some peculiarity during getting of extended attributes list by means of getfattr utility. The getfattr utility expects prefix "user." before any extended attribute's name. So, it ignores any names that don't contained such prefix. Such behavior of getfattr utility results in unexpected empty output of extended attributes list even in the case when file (or folder) contains extended attributes. It needs to use empty string as regular expression pattern for names matching (getfattr --match=""). For support of extended attributes in HFS+: 1. It was added necessary on-disk layout declarations related to Attributes tree into hfsplus_raw.h file. 2. It was added attributes.c file with implementation of functionality of manipulation by records in Attributes tree. 3. It was reworked hfsplus_listxattr, hfsplus_getxattr, hfsplus_setxattr functions in ioctl.c. Moreover, it was added hfsplus_removexattr method.

If the NBD server opened the target with neither O_SYNC nor O_DSYNC, however, the device will be effectively backed by a writeback cache. Without issuing flushes properly, operation of the NBD device will not be safe against power losses. The NBD protocol has support for both a cache flush command and a FUA command flag; the server will also pass a flag to note its support for these features. This patch adds support for the cache flush command and flag. In the kernel, we receive the flags via the NBD_SET_FLAGS ioctl, and map NBD_FLAG_SEND_FLUSH to the argument of blk_queue_flush. When the flag is active the block layer will send REQ_FLUSH requests, which we translate to NBD_CMD_FLUSH commands. FUA support is not included in this patch because all free software servers implement it with a full fdatasync; thus it has no advantage over supporting flush only. Because I [Paolo] cannot really benchmark it in a realistic scenario, I cannot tell if it is a good idea or not. It is also not clear if it is valid for an NBD server to support FUA but not flush. The Linux block layer gives a warning for this combination, the NBD protocol documentation says nothing about it. The patch also fixes a small problem in the handling of flags: nbd->flags must be cleared at the end of NBD_DO_IT, but the driver was not doing that. The bug manifests itself as follows. Suppose you two different client/server pairs to start the NBD device. Suppose also that the first client supports NBD_SET_FLAGS, and the first server sends NBD_FLAG_SEND_FLUSH; the second pair instead does neither of these two things. Before this patch, the second invocation of NBD_DO_IT will use a stale value of nbd->flags, and the second server will issue an error every time it receives an NBD_CMD_FLUSH command. This bug is pre-existing, but it becomes much more important after this patch; flush failures make the device pretty much unusable, unlike Signed-off-by: Paolo Bonzini Signed-off-by: Alex Bligh Acked-by: Paul Clements Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/uapi/linux/nbd.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'include/uapi/linux') diff --git a/include/uapi/linux/nbd.h b/include/uapi/linux/nbd.h index dfb514472cbc..4f52549b23ff 100644 --- a/include/uapi/linux/nbd.h +++ b/include/uapi/linux/nbd.h @@ -33,13 +33,14 @@ enum { NBD_CMD_READ = 0, NBD_CMD_WRITE = 1, NBD_CMD_DISC = 2, - /* there is a gap here to match userspace */ + NBD_CMD_FLUSH = 3, NBD_CMD_TRIM = 4 }; /* values for flags field */ #define NBD_FLAG_HAS_FLAGS (1 << 0) /* nbd-server supports flags */ #define NBD_FLAG_READ_ONLY (1 << 1) /* device is read-only */ +#define NBD_FLAG_SEND_FLUSH (1 << 2) /* can flush writeback cache */ /* there is a gap here to match userspace */ #define NBD_FLAG_SEND_TRIM (1 << 5) /* send trim/discard */ -- cgit v1.2.3 From 02cde50b7ea74557d32ff778c73809322445ccd2 Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Fri, 1 Mar 2013 22:45:49 +0000 Subject: dm ioctl: optimize functions without variable params Device-mapper ioctls receive and send data in a buffer supplied by userspace. The buffer has two parts. The first part contains a 'struct dm_ioctl' and has a fixed size. The second part depends on the ioctl and has a variable size. This patch recognises the specific ioctls that do not use the variable part of the buffer and skips allocating memory for it. In particular, when a device is suspended and a resume ioctl is sent, this now avoid memory allocation completely. The variable "struct dm_ioctl tmp" is moved from the function copy_params to its caller ctl_ioctl and renamed to param_kernel. It is used directly when the ioctl function doesn't need any arguments.
