2011-09-19net: activity_stats: Add statistics for network transmission activityMike Chan
When enabled, tracks the frequency of network transmissions (inbound and outbound) and buckets them accordingly. Buckets are determined by time between network activity. Each bucket represents the number of network transmisions that were N sec or longer apart. Where N is defined as 1 << bucket index. This network pattern tracking is particularly useful for wireless networks (ie: 3G) where batching network activity closely together is more power efficient than far apart. New file: /proc/net/stat/activity output: Min Bucket(sec) Count 1 7 2 0 4 1 8 0 16 0 32 2 64 1 128 0 Change-Id: I15136982e997f7f6120f0b46074bfd87e121a6b0 Signed-off-by: Mike Chan <mike@android.com>

2010-10-20ceph: factor out libceph from Ceph file systemYehuda Sadeh
This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil <sage@newdream.net>
2010-08-05DNS: Separate out CIFS DNS Resolver codeWang Lei
Separate out the DNS resolver key type from the CIFS filesystem into its own module so that it can be made available for general use, including the AFS filesystem module. This facility makes it possible for the kernel to upcall to userspace to have it issue DNS requests, package up the replies and present them to the kernel in a useful form. The kernel is then able to cache the DNS replies as keys can be retained in keyrings. Resolver keys are of type "dns_resolver" and have a case-insensitive description that is of the form "[<type>:]<domain_name>". The optional <type> indicates the particular DNS lookup and packaging that's required. The <domain_name> is the query to be made. If <type> isn't given, a basic hostname to IP address lookup is made, and the result is stored in the key in the form of a printable string consisting of a comma-separated list of IPv4 and IPv6 addresses. This key type is supported by userspace helpers driven from /sbin/request-key and configured through /etc/request-key.conf. The cifs.upcall utility is invoked for UNC path server name to IP address resolution. The CIFS functionality is encapsulated by the dns_resolve_unc_to_ip() function, which is used to resolve a UNC path to an IP address for CIFS filesystem. This part remains in the CIFS module for now. See the added Documentation/networking/dns_resolver.txt for more information.

2010-04-03l2tp: Split pppol2tp patch into separate l2tp and ppp partsJames Chapman
This patch splits the pppol2tp driver into separate L2TP and PPP parts to prepare for L2TPv3 support. In L2TPv3, protocols other than PPP can be carried, so this split creates a common L2TP core that will handle the common L2TP bits which protocol support modules such as PPP will use. Note that the existing pppol2tp module is split into l2tp_core and l2tp_ppp by this change. There are no feature changes here. Internally, however, there are significant changes, mostly to handle the separation of PPP-specific data from the L2TP session and to provide hooks in the core for modules like PPP to access.

2010-04-03l2tp: Relocate pppol2tp driver to new net/l2tp directoryJames Chapman
This patch moves the existing pppol2tp driver from drivers/net into a new net/l2tp directory, which is where the upcoming L2TPv3 code will live. The existing CONFIG_PPPOL2TP config option is left in its current place to avoid "make oldconfig" issues when an existing pppol2tp user takes this change. (This is the same approach used for the pppoatm driver, which moved to net/atm.) There are no code changes. The existing drivers/net/pppol2tp.c is simply moved to net/l2tp.

2009-06-09net: add IEEE 802.15.4 socket family implementationSergey Lapin
Add support for communication over IEEE 802.15.4 networks. This implementation is neither certified nor complete, but aims to that goal. This commit contains only the socket interface for communication over IEEE 802.15.4 networks. One can either send RAW datagrams or use SOCK_DGRAM to encapsulate data inside normal IEEE 802.15.4 packets. Configuration interface, drivers and software MAC 802.15.4 implementation will follow. Initial implementation was done by Maxim Gorbachyov, Maxim Osipov and Pavel Smolensky as a research project at Siemens AG. Later the stack was heavily reworked to better suit the linux networking model, and is now maitained as an open project partially sponsored by Siemens.

2008-10-08net: Distributed Switch Architecture protocol supportLennert Buytenhek
Distributed Switch Architecture is a protocol for managing hardware switch chips. It consists of a set of MII management registers and commands to configure the switch, and an ethernet header format to signal which of the ports of the switch a packet was received from or is intended to be sent to. The switches that this driver supports are typically embedded in access points and routers, and a typical setup with a DSA switch looks something like this: +-----------+ +-----------+ | | RGMII | | | +-------+ +------ 1000baseT MDI ("WAN") | | | 6-port +------ 1000baseT MDI ("LAN1") | CPU | | ethernet +------ 1000baseT MDI ("LAN2") | |MIImgmt| switch +------ 1000baseT MDI ("LAN3") | +-------+ w/5 PHYs +------ 1000baseT MDI ("LAN4") | | | | +-----------+ +-----------+ The switch driver presents each port on the switch as a separate network interface to Linux, polls the switch to maintain software link state of those ports, forwards MII management interface accesses to those network interfaces (e.g. as done by ethtool) to the switch, and exposes the switch's hardware statistics counters via the appropriate Linux kernel interfaces. This initial patch supports the MII management interface register layout of the Marvell 88E6123, 88E6161 and 88E6165 switch chips, and supports the "Ethertype DSA" packet tagging format. (There is no officially registered ethertype for the Ethertype DSA packet format, so we just grab a random one. The ethertype to use is programmed into the switch, and the switch driver uses the value of ETH_P_EDSA for this, so this define can be changed at any time in the future if the one we chose is allocated to another protocol or if Ethertype DSA gets its own officially registered ethertype, and everything will continue to work.)
