* strparser: Stream parser for messagesTom Herbert2016-08-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces a utility for parsing application layer protocol messages in a TCP stream. This is a generalization of the mechanism implemented of Kernel Connection Multiplexor. The API includes a context structure, a set of callbacks, utility functions, and a data ready function. A stream parser instance is defined by a strparse structure that is bound to a TCP socket. The function to initialize the structure is: int strp_init(struct strparser *strp, struct sock *csk, struct strp_callbacks *cb); csk is the TCP socket being bound to and cb are the parser callbacks. The upper layer calls strp_tcp_data_ready when data is ready on the lower socket for strparser to process. This should be called from a data_ready callback that is set on the socket: void strp_tcp_data_ready(struct strparser *strp); A parser is bound to a TCP socket by setting data_ready function to strp_tcp_data_ready so that all receive indications on the socket go through the parser. This is assumes that sk_user_data is set to the strparser structure. There are four callbacks. - parse_msg is called to parse the message (returns length or error). - rcv_msg is called when a complete message has been received - read_sock_done is called when data_ready function exits - abort_parser is called to abort the parser The input to parse_msg is an skbuff which contains next message under construction. The backend processing of parse_msg will parse the application layer protocol headers to determine the length of the message in the stream. The possible return values are: >0 : indicates length of successfully parsed message 0 : indicates more data must be received to parse the message -ESTRPIPE : current message should not be processed by the kernel, return control of the socket to userspace which can proceed to read the messages itself other < 0 : Error is parsing, give control back to userspace assuming that synchronzation is lost and the stream is unrecoverable (application expected to close TCP socket) In the case of error return (< 0) strparse will stop the parser and report and error to userspace. The application must deal with the error. To handle the error the strparser is unbound from the TCP socket. If the error indicates that the stream TCP socket is at recoverable point (ESTRPIPE) then the application can read the TCP socket to process the stream. Once the application has dealt with the exceptions in the stream, it may again bind the socket to a strparser to continue data operations. Note that ENODATA may be returned to the application. In this case parse_msg returned -ESTRPIPE, however strparser was unable to maintain synchronization of the stream (i.e. some of the message in question was already read by the parser). strp_pause and strp_unpause are used to provide flow control. For instance, if rcv_msg is called but the upper layer can't immediately consume the message it can hold the message and pause strparser.

* net/ncsi: Resource managementGavin Shan2016-07-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NCSI spec (DSP0222) defines several objects: package, channel, mode, filter, version and statistics etc. This introduces the data structs to represent those objects and implement functions to manage them. Also, this introduces CONFIG_NET_NCSI for the newly implemented NCSI stack. * The user (e.g. netdev driver) dereference NCSI device by "struct ncsi_dev", which is embedded to "struct ncsi_dev_priv". The later one is used by NCSI stack internally. * Every NCSI device can have multiple packages simultaneously, up to 8 packages. It's represented by "struct ncsi_package" and identified by 3-bits ID. * Every NCSI package can have multiple channels, up to 32. It's represented by "struct ncsi_channel" and identified by 5-bits ID. * Every NCSI channel has version, statistics, various modes and filters. They are represented by "struct ncsi_channel_version", "struct ncsi_channel_stats", "struct ncsi_channel_mode" and "struct ncsi_channel_filter" separately. * Apart from AEN (Asynchronous Event Notification), the NCSI stack works in terms of command and response. This introduces "struct ncsi_req" to represent a complete NCSI transaction made of NCSI request and response. link: https://www.dmtf.org/sites/default/files/standards/documents/DSP0222_1.1.0.pdf Signed-off-by: Gavin Shan <gwshan@linux.vnet.ibm.com> Acked-by: Joel Stanley <joel@jms.id.au> Signed-off-by: David S.

| * make default ->i_fop have ->open() fail with ENXIOAl Viro2014-12-101-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As it is, default ->i_fop has NULL ->open() (along with all other methods). The only case where it matters is reopening (via procfs symlink) a file that didn't get its ->f_op from ->i_fop - anything else will have ->i_fop assigned to something sane (default would fail on read/write/ioctl/etc.). Unfortunately, such case exists - alloc_file() users, especially anon_get_file() ones. There we have tons of opened files of very different kinds sharing the same inode. As the result, attempt to reopen those via procfs succeeds and you get a descriptor you can't do anything with. Moreover, in case of sockets we set ->i_fop that will only be used on such reopen attempts - and put a failing ->open() into it to make sure those do not succeed. It would be simpler to put such ->open() into default ->i_fop and leave it unchanged both for anon inode (as we do anyway) and for socket ones. Result: * everything going through do_dentry_open() works as it used to * sock_no_open() kludge is gone * attempts to reopen anon-inode files fail as they really ought to * ditto for aio_private_file() * ditto for perfmon - this one actually tried to imitate sock_no_open() trick, but failed to set ->i_fop, so in the current tree reopens succeed and yield completely useless descriptor. Intent clearly had been to fail with -ENXIO on such reopens; now it actually does. * everything else that used alloc_file() keeps working - it has ->i_fop set for its inodes anyway Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves generic code which is used by bluetooth and ieee802154 6lowpan to a new net/6lowpan directory.

* net/hsr: Add support for the High-availability Seamless Redundancy protocol ↵Arvid Brodin2013-11-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | (HSRv0) High-availability Seamless Redundancy ("HSR") provides instant failover redundancy for Ethernet networks. It requires a special network topology where all nodes are connected in a ring (each node having two physical network interfaces). It is suited for applications that demand high availability and very short reaction time. HSR acts on the Ethernet layer, using a registered Ethernet protocol type to send special HSR frames in both directions over the ring. The driver creates virtual network interfaces that can be used just like any ordinary Linux network interface, for IP/TCP/UDP traffic etc. All nodes in the network ring must be HSR capable. This code is a "best effort" to comply with the HSR standard as described in IEC 62439-3:2010 (HSRv0). Signed-off-by: Arvid Brodin <arvid.brodin@xdin.com> Signed-off-by: David S.

* MPLS: Add limited GSO supportSimon Horman2013-05-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the case where a non-MPLS packet is received and an MPLS stack is added it may well be the case that the original skb is GSO but the NIC used for transmit does not support GSO of MPLS packets. The aim of this code is to provide GSO in software for MPLS packets whose skbs are GSO. SKB Usage: When an implementation adds an MPLS stack to a non-MPLS packet it should do the following to skb metadata: * Set skb->inner_protocol to the old non-MPLS ethertype of the packet. skb->inner_protocol is added by this patch. * Set skb->protocol to the new MPLS ethertype of the packet. * Set skb->network_header to correspond to the end of the L3 header, including the MPLS label stack. I have posted a patch, "[PATCH v3.29] datapath: Add basic MPLS support to kernel" which adds MPLS support to the kernel datapath of Open vSwtich. That patch sets the above requirements in datapath/actions.c:push_mpls() and was used to exercise this code. The datapath patch is against the Open vSwtich tree but it is intended that it be added to the Open vSwtich code present in the mainline Linux kernel at some point. Features: I believe that the approach that I have taken is at least partially consistent with the handling of other protocols. Jesse, I understand that you have some ideas here. I am more than happy to change my implementation. This patch adds dev->mpls_features which may be used by devices to advertise features supported for MPLS packets. A new NETIF_F_MPLS_GSO feature is added for devices which support hardware MPLS GSO offload. Currently no devices support this and MPLS GSO always falls back to software. Alternate Implementation: One possible alternate implementation is to teach netif_skb_features() and skb_network_protocol() about MPLS, in a similar way to their understanding of VLANs. I believe this would avoid the need for net/mpls/mpls_gso.c and in particular the calls to __skb_push() and __skb_push() in mpls_gso_segment(). I have decided on the implementation in this patch as it should not introduce any overhead in the case where mpls_gso is not compiled into the kernel or inserted as a module. MPLS GSO suggested by Jesse Gross. Based in part on "v4 GRE: Add TCP segmentation offload for GRE" by Pravin B Shelar.

* VSOCK: Introduce VM SocketsAndy King2013-02-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VM Sockets allows communication between virtual machines and the hypervisor. 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.

* wanrouter: completely decouple obsolete code from kernel.Paul Gortmaker2013-01-311-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The original suggestion to delete wanrouter started earlier with the mainline commit f0d1b3c2bcc5de8a17af5f2274f7fcde8292b5fc ("net/wanrouter: Deprecate and schedule for removal") in May 2012. More importantly, Dan Carpenter found[1] that the driver had a fundamental breakage introduced back in 2008, with commit 7be6065b39c3 ("netdevice wanrouter: Convert directly reference of netdev->priv"). So we know with certainty that the code hasn't been used by anyone willing to at least take the effort to send an e-mail report of breakage for at least 4 years. This commit does a decouple of the wanrouter subsystem, by going after the Makefile/Kconfig and similar files, so that these mainline files that we are keeping do not have the big wanrouter file/driver deletion commit tied into their history. Once this commit is in place, we then can remove the obsolete cyclomx drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.

| | | | | | | | | | | | | | | | | | | | | Open vSwitch is a multilayer Ethernet switch targeted at virtualized environments. In addition to supporting a variety of features expected in a traditional hardware switch, it enables fine-grained programmatic extension and flow-based control of the network. This control is useful in a wide variety of applications but is particularly important in multi-server virtualization deployments, which are often characterized by highly dynamic endpoints and the need to maintain logical abstractions for multiple tenants. The Open vSwitch datapath provides an in-kernel fast path for packet forwarding. It is complemented by a userspace daemon, ovs-vswitchd, which is able to accept configuration from a variety of sources and translate it into packet processing rules.

* DNS: Separate out CIFS DNS Resolver codeWang Lei2010-08-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* net: add IEEE 802.15.4 socket family implementationSergey Lapin2009-06-091-0/+1
| | | | | | | | | | | | | | | | | | | | 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.

The DCB feature support included are Priority Grouping (PG) - which allows bandwidth guarantees to be allocated to groups to traffic based on the 802.1q priority, and Priority Based Flow Control (PFC) - which introduces a new MAC control PAUSE frame which works at granularity of the 802.1p priority instead of the link (IEEE 802.3x).

* net: Distributed Switch Architecture protocol supportLennert Buytenhek2008-10-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)
