CIPSO Format + +Option type: 134 (Class 0, Number 6, Copy on Fragmentation) +Option length: Variable + +This option permits security related information to be passed between +systems within a single Domain of Interpretation (DOI). A DOI is a +collection of systems which agree on the meaning of particular values +in the security option. An authority that has been assigned a DOI +identifier will define a mapping between appropriate CIPSO field values +and their human readable equivalent. This authority will distribute that +mapping to hosts within the authority's domain. These mappings may be +sensitive, therefore a DOI authority is not required to make these +mappings available to anyone other than the systems that are included in +the DOI. + +This option MUST be copied on fragmentation. This option appears at most +once in a datagram. All multi-octet fields in the option are defined to be +transmitted in network byte order. The format of this option is as follows: + ++----------+----------+------//------+-----------//---------+ +| 10000110 | LLLLLLLL | DDDDDDDDDDDD | TTTTTTTTTTTTTTTTTTTT | ++----------+----------+------//------+-----------//---------+ + + TYPE=134 OPTION DOMAIN OF TAGS + LENGTH INTERPRETATION + + + Figure 1. CIPSO Format + + +3.1 Type + +This field is 1 octet in length. Its value is 134. + + +3.2 Length + +This field is 1 octet in length. It is the total length of the option +including the type and length fields. With the current IP header length +restriction of 40 octets the value of this field MUST not exceed 40. + + +3.3 Domain of Interpretation Identifier + +This field is an unsigned 32 bit integer. The value 0 is reserved and MUST +not appear as the DOI identifier in any CIPSO option. Implementations +should assume that the DOI identifier field is not aligned on any particular +byte boundary. + +To conserve space in the protocol, security levels and categories are +represented by numbers rather than their ASCII equivalent. This requires +a mapping table within CIPSO hosts to map these numbers to their +corresponding ASCII representations. Non-related groups of systems may + + + +Internet Draft, Expires 15 Jan 93 [PAGE 2] + + + +CIPSO INTERNET DRAFT 16 July, 1992 + + + +have their own unique mappings. For example, one group of systems may +use the number 5 to represent Unclassified while another group may use the +number 1 to represent that same security level. The DOI identifier is used +to identify which mapping was used for the values within the option. + + +3.4 Tag Types + +A common format for passing security related information is necessary +for interoperability. CIPSO uses sets of "tags" to contain the security +information relevant to the data in the IP packet. Each tag begins with +a tag type identifier followed by the length of the tag and ends with the +actual security information to be passed. All multi-octet fields in a tag +are defined to be transmitted in network byte order. Like the DOI +identifier field in the CIPSO header, implementations should assume that +all tags, as well as fields within a tag, are not aligned on any particular +octet boundary. The tag types defined in this document contain alignment +bytes to assist alignment of some information, however alignment can not +be guaranteed if CIPSO is not the first IP option. + +CIPSO tag types 0 through 127 are reserved for defining standard tag +formats. Their definitions will be published in RFCs. Tag types whose +identifiers are greater than 127 are defined by the DOI authority and may +only be meaningful in certain Domains of Interpretation. For these tag +types, implementations will require the DOI identifier as well as the tag +number to determine the security policy and the format associated with the +tag. Use of tag types above 127 are restricted to closed networks where +interoperability with other networks will not be an issue. Implementations +that support a tag type greater than 127 MUST support at least one DOI that +requires only tag types 1 to 127. + +Tag type 0 is reserved. Tag types 1, 2, and 5 are defined in this +Internet Draft. Types 3 and 4 are reserved for work in progress. +The standard format for all current and future CIPSO tags is shown below: + ++----------+----------+--------//--------+ +| TTTTTTTT | LLLLLLLL | IIIIIIIIIIIIIIII | ++----------+----------+--------//--------+ + TAG TAG TAG + TYPE LENGTH INFORMATION + + Figure 2: Standard Tag Format + +In the three tag types described in this document, the length and count +restrictions are based on the current IP limitation of 40 octets for all +IP options. If the IP header is later expanded, then the length and count +restrictions specified in this document may increase to use the full area +provided for IP options. + + +3.4.1 Tag Type Classes + +Tag classes consist of tag types that have common processing requirements +and support the same security policy. The three tags defined in this +Internet Draft belong to the Mandatory Access Control (MAC) Sensitivity + + + +Internet Draft, Expires 15 Jan 93 [PAGE 3] + + + +CIPSO INTERNET DRAFT 16 July, 1992 + + + +class and support the MAC Sensitivity security policy. + + +3.4.2 Tag Type 1 + +This is referred to as the "bit-mapped" tag type. Tag type 1 is included +in the MAC Sensitivity tag type class. The format of this tag type is as +follows: + ++----------+----------+----------+----------+--------//---------+ +| 00000001 | LLLLLLLL | 00000000 | LLLLLLLL | CCCCCCCCCCCCCCCCC | ++----------+----------+----------+----------+--------//---------+ + + TAG TAG ALIGNMENT SENSITIVITY BIT MAP OF + TYPE LENGTH OCTET LEVEL CATEGORIES + + Figure 3.

It is the total length of the tag type +including the type and length fields. With the current IP header length +restriction of 40 bytes the value within this field is between 4 and 34. + + +3.4.2.3 Alignment Octet + +This field is 1 octet in length and always has the value of 0. Its purpose +is to align the category bitmap field on an even octet boundary. This will +speed many implementations including router implementations. + + +3.4.2.4 Sensitivity Level + +This field is 1 octet in length. Its value is from 0 to 255. The values +are ordered with 0 being the minimum value and 255 representing the maximum +value. + + +3.4.2.5 Bit Map of Categories + +The length of this field is variable and ranges from 0 to 30 octets. This +provides representation of categories 0 to 239. The ordering of the bits +is left to right or MSB to LSB. For example category 0 is represented by +the most significant bit of the first byte and category 15 is represented +by the least significant bit of the second byte. Figure 4 graphically +shows this ordering. Bit N is binary 1 if category N is part of the label +for the datagram, and bit N is binary 0 if category N is not part of the +label.

To +support these routers there is an optimized form of tag type 1. The format +does not change. The only change is to the category bitmap which is set to +a constant length of 10 octets. Trailing octets required to fill out the 10 +octets are zero filled. Ten octets, allowing for 80 categories, was chosen +because it makes the total length of the CIPSO option 20 octets. If CIPSO +is the only option then the option will be full word aligned and additional +filler octets will not be required. + + +3.4.3 Tag Type 2 + +This is referred to as the "enumerated" tag type. It is used to describe +large but sparsely populated sets of categories. Tag type 2 is in the MAC +Sensitivity tag type class. The format of this tag type is as follows: + ++----------+----------+----------+----------+-------------//-------------+ +| 00000010 | LLLLLLLL | 00000000 | LLLLLLLL | CCCCCCCCCCCCCCCCCCCCCCCCCC | ++----------+----------+----------+----------+-------------//-------------+ + + TAG TAG ALIGNMENT SENSITIVITY ENUMERATED + TYPE LENGTH OCTET LEVEL CATEGORIES + + Figure 5.

Its value is from 0 to 255. The values +are ordered with 0 being the minimum value and 255 representing the +maximum value. + + +3.4.3.5 Enumerated Categories + +In this tag, categories are represented by their actual value rather than +by their position within a bit field. The length of each category is 2 +octets. Up to 15 categories may be represented by this tag. Valid values +for categories are 0 to 65534. Category 65535 is not a valid category +value. The categories MUST be listed in ascending order within the tag. + + +3.4.4 Tag Type 5 + +This is referred to as the "range" tag type. It is used to represent +labels where all categories in a range, or set of ranges, are included +in the sensitivity label. Tag type 5 is in the MAC Sensitivity tag type +class.

Its value is from 0 to 255. The values +are ordered with 0 being the minimum value and 255 representing the maximum +value. + + +3.4.4.5 Category Ranges + +A category range is a 4 octet field comprised of the 2 octet index of the +highest numbered category followed by the 2 octet index of the lowest +numbered category. These range endpoints are inclusive within the range of +categories. All categories within a range are included in the sensitivity +label. This tag may contain a maximum of 7 category pairs. The bottom +category endpoint for the last pair in the tag MAY be omitted and SHOULD be +assumed to be 0. The ranges MUST be non-overlapping and be listed in +descending order. Valid values for categories are 0 to 65534. Category +65535 is not a valid category value. + + +3.4.5 Minimum Requirements + +A CIPSO implementation MUST be capable of generating at least tag type 1 in +the non-optimized form. In addition, a CIPSO implementation MUST be able +to receive any valid tag type 1 even those using the optimized tag type 1 +format. + + +4. Configuration Parameters + +The configuration parameters defined below are required for all CIPSO hosts, +gateways, and routers that support multiple sensitivity labels. A CIPSO +host is defined to be the origination or destination system for an IP +datagram. A CIPSO gateway provides IP routing services between two or more +IP networks and may be required to perform label translations between +networks. A CIPSO gateway may be an enhanced CIPSO host or it may just +provide gateway services with no end system CIPSO capabilities. A CIPSO +router is a dedicated IP router that routes IP datagrams between two or more +IP networks. + +An implementation of CIPSO on a host MUST have the capability to reject a +datagram for reasons that the information contained can not be adequately +protected by the receiving host or if acceptance may result in violation of +the host or network security policy. In addition, a CIPSO gateway or router +MUST be able to reject datagrams going to networks that can not provide +adequate protection or may violate the network's security policy. To +provide this capability the following minimal set of configuration +parameters are required for CIPSO implementations: + +HOST_LABEL_MAX - This parameter contains the maximum sensitivity label that +a CIPSO host is authorized to handle. All datagrams that have a label +greater than this maximum MUST be rejected by the CIPSO host. This +parameter does not apply to CIPSO gateways or routers. This parameter need +not be defined explicitly as it can be implicitly derived from the +PORT_LABEL_MAX parameters for the associated interfaces. + + + +Internet Draft, Expires 15 Jan 93 [PAGE 7] + + + +CIPSO INTERNET DRAFT 16 July, 1992 + + + + +HOST_LABEL_MIN - This parameter contains the minimum sensitivity label that +a CIPSO host is authorized to handle. All datagrams that have a label less +than this minimum MUST be rejected by the CIPSO host. This parameter does +not apply to CIPSO gateways or routers. This parameter need not be defined +explicitly as it can be implicitly derived from the PORT_LABEL_MIN +parameters for the associated interfaces. + +PORT_LABEL_MAX - This parameter contains the maximum sensitivity label for +all datagrams that may exit a particular network interface port. All +outgoing datagrams that have a label greater than this maximum MUST be +rejected by the CIPSO system. The label within this parameter MUST be +less than or equal to the label within the HOST_LABEL_MAX parameter. This +parameter does not apply to CIPSO hosts that support only one network port. + +PORT_LABEL_MIN - This parameter contains the minimum sensitivity label for +all datagrams that may exit a particular network interface port. All +outgoing datagrams that have a label less than this minimum MUST be +rejected by the CIPSO system. The label within this parameter MUST be +greater than or equal to the label within the HOST_LABEL_MIN parameter. +This parameter does not apply to CIPSO hosts that support only one network +port. + +PORT_DOI - This parameter is used to assign a DOI identifier value to a +particular network interface port. All CIPSO labels within datagrams +going out this port MUST use the specified DOI identifier. All CIPSO +hosts and gateways MUST support either this parameter, the NET_DOI +parameter, or the HOST_DOI parameter. + +NET_DOI - This parameter is used to assign a DOI identifier value to a +particular IP network address. All CIPSO labels within datagrams destined +for the particular IP network MUST use the specified DOI identifier. All +CIPSO hosts and gateways MUST support either this parameter, the PORT_DOI +parameter, or the HOST_DOI parameter. + +HOST_DOI - This parameter is used to assign a DOI identifier value to a +particular IP host address. All CIPSO labels within datagrams destined for +the particular IP host will use the specified DOI identifier. All CIPSO +hosts and gateways MUST support either this parameter, the PORT_DOI +parameter, or the NET_DOI parameter. + +This list represents the minimal set of configuration parameters required +to be compliant. Implementors are encouraged to add to this list to +provide enhanced functionality and control. For example, many security +policies may require both incoming and outgoing datagrams be checked against +the port and host label ranges. + + +4.1 Port Range Parameters + +The labels represented by the PORT_LABEL_MAX and PORT_LABEL_MIN parameters +MAY be in CIPSO or local format. Some CIPSO systems, such as routers, may +want to have the range parameters expressed in CIPSO format so that incoming +labels do not have to be converted to a local format before being compared +against the range. If multiple DOIs are supported by one of these CIPSO + + + +Internet Draft, Expires 15 Jan 93 [PAGE 8] + + + +CIPSO INTERNET DRAFT 16 July, 1992 + + + +systems then multiple port range parameters would be needed, one set for +each DOI supported on a particular port. + +The port range will usually represent the total set of labels that may +exist on the logical network accessed through the corresponding network +interface. It may, however, represent a subset of these labels that are +allowed to enter the CIPSO system. + + +4.2 Single Label CIPSO Hosts + +CIPSO implementations that support only one label are not required to +support the parameters described above. These limited implementations are +only required to support a NET_LABEL parameter. This parameter contains +the CIPSO label that may be inserted in datagrams that exit the host. In +addition, the host MUST reject any incoming datagram that has a label which +is not equivalent to the NET_LABEL parameter. + + +5. Handling Procedures + +This section describes the processing requirements for incoming and +outgoing IP datagrams. Just providing the correct CIPSO label format +is not enough. Assumptions will be made by one system on how a +receiving system will handle the CIPSO label. Wrong assumptions may +lead to non-interoperability or even a security incident. The +requirements described below represent the minimal set needed for +interoperability and that provide users some level of confidence. +Many other requirements could be added to increase user confidence, +however at the risk of restricting creativity and limiting vendor +participation. + + +5.1 Input Procedures + +All datagrams received through a network port MUST have a security label +associated with them, either contained in the datagram or assigned to the +receiving port. Without this label the host, gateway, or router will not +have the information it needs to make security decisions. This security +label will be obtained from the CIPSO if the option is present in the +datagram. See section 4.1.2 for handling procedures for unlabeled +datagrams. This label will be compared against the PORT (if appropriate) +and HOST configuration parameters defined in section 3. + +If any field within the CIPSO option, such as the DOI identifier, is not +recognized the IP datagram is discarded and an ICMP "parameter problem" +(type 12) is generated and returned. The ICMP code field is set to "bad +parameter" (code 0) and the pointer is set to the start of the CIPSO field +that is unrecognized. + +If the contents of the CIPSO are valid but the security label is +outside of the configured host or port label range, the datagram is +discarded and an ICMP "destination unreachable" (type 3) is generated +and returned. The code field of the ICMP is set to "communication with +destination network administratively prohibited" (code 9) or to + + + +Internet Draft, Expires 15 Jan 93 [PAGE 9] + + + +CIPSO INTERNET DRAFT 16 July, 1992 + + + +"communication with destination host administratively prohibited" +(code 10). The value of the code field used is dependent upon whether +the originator of the ICMP message is acting as a CIPSO host or a CIPSO +gateway. The recipient of the ICMP message MUST be able to handle either +value. The same procedure is performed if a CIPSO can not be added to an +IP packet because it is too large to fit in the IP options area. + +If the error is triggered by receipt of an ICMP message, the message +is discarded and no response is permitted (consistent with general ICMP +processing rules). + + +5.1.1 Unrecognized tag types + +The default condition for any CIPSO implementation is that an +unrecognized tag type MUST be treated as a "parameter problem" and +handled as described in section 4.1. A CIPSO implementation MAY allow +the system administrator to identify tag types that may safely be +ignored. This capability is an allowable enhancement, not a +requirement. + + +5.1.2 Unlabeled Packets + +A network port may be configured to not require a CIPSO label for all +incoming datagrams. For this configuration a CIPSO label must be +assigned to that network port and associated with all unlabeled IP +datagrams. This capability might be used for single level networks or +networks that have CIPSO and non-CIPSO hosts and the non-CIPSO hosts +all operate at the same label. + +If a CIPSO option is required and none is found, the datagram is +discarded and an ICMP "parameter problem" (type 12) is generated and +returned to the originator of the datagram. The code field of the ICMP +is set to "option missing" (code 1) and the ICMP pointer is set to 134 +(the value of the option type for the missing CIPSO option). + + +5.2 Output Procedures + +A CIPSO option MUST appear only once in a datagram. Only one tag type +from the MAC Sensitivity class MAY be included in a CIPSO option. Given +the current set of defined tag types, this means that CIPSO labels at +first will contain only one tag. + +All datagrams leaving a CIPSO system MUST meet the following condition: + + PORT_LABEL_MIN <= CIPSO label <= PORT_LABEL_MAX + +If this condition is not satisfied the datagram MUST be discarded. +If the CIPSO system only supports one port, the HOST_LABEL_MIN and the +HOST_LABEL_MAX parameters MAY be substituted for the PORT parameters in +the above condition. + +The DOI identifier to be used for all outgoing datagrams is configured by + + + +Internet Draft, Expires 15 Jan 93 [PAGE 10] + + + +CIPSO INTERNET DRAFT 16 July, 1992 + + + +the administrator. If port level DOI identifier assignment is used, then +the PORT_DOI configuration parameter MUST contain the DOI identifier to +use. If network level DOI assignment is used, then the NET_DOI parameter +MUST contain the DOI identifier to use. And if host level DOI assignment +is employed, then the HOST_DOI parameter MUST contain the DOI identifier +to use. A CIPSO implementation need only support one level of DOI +assignment. + + +5.3 DOI Processing Requirements + +A CIPSO implementation MUST support at least one DOI and SHOULD support +multiple DOIs. System and network administrators are cautioned to +ensure that at least one DOI is common within an IP network to allow for +broadcasting of IP datagrams. + +CIPSO gateways MUST be capable of translating a CIPSO option from one +DOI to another when forwarding datagrams between networks. For +efficiency purposes this capability is only a desired feature for CIPSO +routers. + + +5.4 Label of ICMP Messages + +The CIPSO label to be used on all outgoing ICMP messages MUST be equivalent +to the label of the datagram that caused the ICMP message. If the ICMP was +generated due to a problem associated with the original CIPSO label then the +following responses are allowed: + + a. Use the CIPSO label of the original IP datagram + b. Drop the original datagram with no return message generated + +In most cases these options will have the same effect. If you can not +interpret the label or if it is outside the label range of your host or +interface then an ICMP message with the same label will probably not be +able to exit the system. + + +6. Assignment of DOI Identifier Numbers = + +Requests for assignment of a DOI identifier number should be addressed to +the Internet Assigned Numbers Authority (IANA). + + +7.

It +is composed of three main components, the protocol engines, the communication +layer, and the kernel security module API. + + * Protocol Engines + +The protocol engines are responsible for both applying and retrieving the +network packet's security attributes. If any translation between the network +security attributes and those on the host are required then the protocol +engine will handle those tasks as well. Other kernel subsystems should +refrain from calling the protocol engines directly, instead they should use +the NetLabel kernel security module API described below. + +Detailed information about each NetLabel protocol engine can be found in this +directory, consult '00-INDEX' for filenames. + + * Communication Layer + +The communication layer exists to allow NetLabel configuration and monitoring +from user space. The NetLabel communication layer uses a message based +protocol built on top of the Generic NETLINK transport mechanism. The exact +formatting of these NetLabel messages as well as the Generic NETLINK family +names can be found in the the 'net/netlabel/' directory as comments in the +header files as well as in 'include/net/netlabel.h'. + + * Security Module API + +The purpose of the NetLabel security module API is to provide a protocol +independent interface to the underlying NetLabel protocol engines. In addition +to protocol independence, the security module API is designed to be completely +LSM independent which should allow multiple LSMs to leverage the same code +base. + +Detailed information about the NetLabel security module API can be found in the +'include/net/netlabel.h' header file as well as the 'lsm_interface.txt' file +found in this directory. diff --git a/trunk/Documentation/netlabel/lsm_interface.txt b/trunk/Documentation/netlabel/lsm_interface.txt new file mode 100644 index 000000000000..98dd9f7430f2 --- /dev/null +++ b/trunk/Documentation/netlabel/lsm_interface.txt @@ -0,0 +1,47 @@ +NetLabel Linux Security Module Interface +============================================================================== +Paul Moore, paul.moore@hp.com + +May 17, 2006 + + * Overview + +NetLabel is a mechanism which can set and retrieve security attributes from +network packets. It is intended to be used by LSM developers who want to make +use of a common code base for several different packet labeling protocols. +The NetLabel security module API is defined in 'include/net/netlabel.h' but a +brief overview is given below. + + * NetLabel Security Attributes + +Since NetLabel supports multiple different packet labeling protocols and LSMs +it uses the concept of security attributes to refer to the packet's security +labels. The NetLabel security attributes are defined by the +'netlbl_lsm_secattr' structure in the NetLabel header file. Internally the +NetLabel subsystem converts the security attributes to and from the correct +low-level packet label depending on the NetLabel build time and run time +configuration. It is up to the LSM developer to translate the NetLabel +security attributes into whatever security identifiers are in use for their +particular LSM. + + * NetLabel LSM Protocol Operations + +These are the functions which allow the LSM developer to manipulate the labels +on outgoing packets as well as read the labels on incoming packets. Functions +exist to operate both on sockets as well as the sk_buffs directly. These high +level functions are translated into low level protocol operations based on how +the administrator has configured the NetLabel subsystem. + + * NetLabel Label Mapping Cache Operations + +Depending on the exact configuration, translation between the network packet +label and the internal LSM security identifier can be time consuming. The +NetLabel label mapping cache is a caching mechanism which can be used to +sidestep much of this overhead once a mapping has been established. Once the +LSM has received a packet, used NetLabel to decode it's security attributes, +and translated the security attributes into a LSM internal identifier the LSM +can use the NetLabel caching functions to associate the LSM internal +identifier with the network packet's label. This means that in the future +when a incoming packet matches a cached value not only are the internal +NetLabel translation mechanisms bypassed but the LSM translation mechanisms are +bypassed as well which should result in a significant reduction in overhead. diff --git a/trunk/Documentation/networking/LICENSE.qla3xxx b/trunk/Documentation/networking/LICENSE.qla3xxx new file mode 100644 index 000000000000..2f2077e34d81 --- /dev/null +++ b/trunk/Documentation/networking/LICENSE.qla3xxx @@ -0,0 +1,46 @@ +Copyright (c) 2003-2006 QLogic Corporation +QLogic Linux Networking HBA Driver + +This program includes a device driver for Linux 2.6 that may be +distributed with QLogic hardware specific firmware binary file. +You may modify and redistribute the device driver code under the +GNU General Public License as published by the Free Software +Foundation (version 2 or a later version). + +You may redistribute the hardware specific firmware binary file +under the following terms: + + 1.

It sits between SCSI Core and SAS LLDDs. The +layout is as follows: while SCSI Core is concerned with +SAM/SPC issues, and a SAS LLDD+sequencer is concerned with +phy/OOB/link management, the SAS layer is concerned with: + + * SAS Phy/Port/HA event management (LLDD generates, + SAS Layer processes), + * SAS Port management (creation/destruction), + * SAS Domain discovery and revalidation, + * SAS Domain device management, + * SCSI Host registration/unregistration, + * Device registration with SCSI Core (SAS) or libata + (SATA), and + * Expander management and exporting expander control + to user space. + +A SAS LLDD is a PCI device driver. It is concerned with +phy/OOB management, and vendor specific tasks and generates +events to the SAS layer. + +The SAS Layer does most SAS tasks as outlined in the SAS 1.1 +spec. + +The sas_ha_struct describes the SAS LLDD to the SAS layer. +Most of it is used by the SAS Layer but a few fields need to +be initialized by the LLDDs. + +After initializing your hardware, from the probe() function +you call sas_register_ha(). It will register your LLDD with +the SCSI subsystem, creating a SCSI host and it will +register your SAS driver with the sysfs SAS tree it creates. +It will then return. Then you enable your phys to actually +start OOB (at which point your driver will start calling the +notify_* event callbacks). + +Structure descriptions: + +struct sas_phy -------------------- +Normally this is statically embedded to your driver's +phy structure: + struct my_phy { + blah; + struct sas_phy sas_phy; + bleh; + }; +And then all the phys are an array of my_phy in your HA +struct (shown below). + +Then as you go along and initialize your phys you also +initialize the sas_phy struct, along with your own +phy structure. + +In general, the phys are managed by the LLDD and the ports +are managed by the SAS layer. So the phys are initialized +and updated by the LLDD and the ports are initialized and +updated by the SAS layer. + +There is a scheme where the LLDD can RW certain fields, +and the SAS layer can only read such ones, and vice versa. +The idea is to avoid unnecessary locking. + +enabled -- must be set (0/1) +id -- must be set [0,MAX_PHYS) +class, proto, type, role, oob_mode, linkrate -- must be set +oob_mode -- you set this when OOB has finished and then notify +the SAS Layer. + +sas_addr -- this normally points to an array holding the sas +address of the phy, possibly somewhere in your my_phy +struct. + +attached_sas_addr -- set this when you (LLDD) receive an +IDENTIFY frame or a FIS frame, _before_ notifying the SAS +layer. The idea is that sometimes the LLDD may want to fake +or provide a different SAS address on that phy/port and this +allows it to do this. At best you should copy the sas +address from the IDENTIFY frame or maybe generate a SAS +address for SATA directly attached devices. The Discover +process may later change this. + +frame_rcvd -- this is where you copy the IDENTIFY/FIS frame +when you get it; you lock, copy, set frame_rcvd_size and +unlock the lock, and then call the event. It is a pointer +since there's no way to know your hw frame size _exactly_, +so you define the actual array in your phy struct and let +this pointer point to it. You copy the frame from your +DMAable memory to that area holding the lock. + +sas_prim -- this is where primitives go when they're +received. See sas.h. Grab the lock, set the primitive, +release the lock, notify. + +port -- this points to the sas_port if the phy belongs +to a port -- the LLDD only reads this. It points to the +sas_port this phy is part of. Set by the SAS Layer. + +ha -- may be set; the SAS layer sets it anyway. + +lldd_phy -- you should set this to point to your phy so you +can find your way around faster when the SAS layer calls one +of your callbacks and passes you a phy. If the sas_phy is +embedded you can also use container_of -- whatever you +prefer. + + +struct sas_port -------------------- +The LLDD doesn't set any fields of this struct -- it only +reads them. They should be self explanatory. + +phy_mask is 32 bit, this should be enough for now, as I +haven't heard of a HA having more than 8 phys. + +lldd_port -- I haven't found use for that -- maybe other +LLDD who wish to have internal port representation can make +use of this. + + +struct sas_ha_struct -------------------- +It normally is statically declared in your own LLDD +structure describing your adapter: +struct my_sas_ha { + blah; + struct sas_ha_struct sas_ha; + struct my_phy phys[MAX_PHYS]; + struct sas_port sas_ports[MAX_PHYS]; /* (1) */ + bleh; +}; + +(1) If your LLDD doesn't have its own port representation. + +What needs to be initialized (sample function given below). + +pcidev +sas_addr -- since the SAS layer doesn't want to mess with + memory allocation, etc, this points to statically + allocated array somewhere (say in your host adapter + structure) and holds the SAS address of the host + adapter as given by you or the manufacturer, etc. +sas_port +sas_phy -- an array of pointers to structures. (see + note above on sas_addr). + These must be set. See more notes below. +num_phys -- the number of phys present in the sas_phy array, + and the number of ports present in the sas_port + array.

Task +Collector Mode is an optional feature for HAs which support +this in their hardware.

There is *no* +queuing of any sort and at any level in a SAS LLDD. + +The use of task::list is two-fold, one for linked commands, +the other discussed below. + +It is possible to queue up more than one task at a time, by +initializing the list element of struct sas_task, and +passing the number of tasks enlisted in this manner in num. + +Returns: -SAS_QUEUE_FULL, -ENOMEM, nothing was queued; + 0, the task(s) were queued. + +If you want to pass num > 1, then either +A) you're the only caller of this function and keep track + of what you've queued to the LLDD, or +B) you know what you're doing and have a strategy of + retrying. + +As opposed to queuing one task at a time (function call), +batch queuing of tasks, by having num > 1, greatly +simplifies LLDD code, sequencer code, and _hardware design_, +and has some performance advantages in certain situations +(DBMS). + +The LLDD advertises if it can take more than one command at +a time at lldd_execute_task(), by setting the +lldd_max_execute_num parameter (controlled by "collector" +module parameter in aic94xx SAS LLDD). + +You should leave this to the default 1, unless you know what +you're doing. + +This is a function of the LLDD, to which the SAS layer can +cater to. + +int lldd_queue_size + The host adapter's queue size.

It is completely managed by the SAS layer. A task +points to a domain device, this is how the SAS LLDD knows +where to send the task(s) to. A SAS LLDD only reads the +contents of the domain_device structure, but it never creates +or destroys one. + +Expander management from User Space +----------------------------------- + +In each expander directory in sysfs, there is a file called +"smp_portal". It is a binary sysfs attribute file, which +implements an SMP portal (Note: this is *NOT* an SMP port), +to which user space applications can send SMP requests and +receive SMP responses. + +Functionality is deceptively simple: + +1. Build the SMP frame you want to send. The format and layout + is described in the SAS spec. Leave the CRC field equal 0. +open(2) +2. Open the expander's SMP portal sysfs file in RW mode. +write(2) +3. Write the frame you built in 1. +read(2) +4. Read the amount of data you expect to receive for the frame you built. + If you receive different amount of data you expected to receive, + then there was some kind of error. +close(2) +All this process is shown in detail in the function do_smp_func() +and its callers, in the file "expander_conf.c". + +The kernel functionality is implemented in the file +"sas_expander.c". + +The program "expander_conf.c" implements this. It takes one +argument, the sysfs file name of the SMP portal to the +expander, and gives expander information, including routing +tables. + +The SMP portal gives you complete control of the expander, +so please be careful. diff --git a/trunk/Documentation/sound/alsa/ALSA-Configuration.txt b/trunk/Documentation/sound/alsa/ALSA-Configuration.txt index f61af23dd85d..e6b57dd46a4f 100644 --- a/trunk/Documentation/sound/alsa/ALSA-Configuration.txt +++ b/trunk/Documentation/sound/alsa/ALSA-Configuration.txt @@ -758,6 +758,7 @@ Prior to version 0.9.0rc4 options had a 'snd_' prefix.

-/* The exp_to_poly and poly_to_exp tables are used to perform efficient - * operations in GF(2^8) represented as GF(2)[x]/w(x) where - * w(x)=x^8+x^6+x^3+x^2+1. We care about doing that because it's part of the - * definition of the RS matrix in the key schedule. Elements of that field - * are polynomials of degree not greater than 7 and all coefficients 0 or 1, - * which can be represented naturally by bytes (just substitute x=2). In that - * form, GF(2^8) addition is the same as bitwise XOR, but GF(2^8) - * multiplication is inefficient without hardware support. To multiply - * faster, I make use of the fact x is a generator for the nonzero elements, - * so that every element p of GF(2)[x]/w(x) is either 0 or equal to (x)^n for - * some n in 0..254. Note that that caret is exponentiation in GF(2^8), - * *not* polynomial notation. So if I want to compute pq where p and q are - * in GF(2^8), I can just say: - * 1. if p=0 or q=0 then pq=0 - * 2. otherwise, find m and n such that p=x^m and q=x^n - * 3. pq=(x^m)(x^n)=x^(m+n), so add m and n and find pq - * The translations in steps 2 and 3 are looked up in the tables - * poly_to_exp (for step 2) and exp_to_poly (for step 3). To see this - * in action, look at the CALC_S macro. As additional wrinkles, note that - * one of my operands is always a constant, so the poly_to_exp lookup on it - * is done in advance; I included the original values in the comments so - * readers can have some chance of recognizing that this *is* the RS matrix - * from the Twofish paper. I've only included the table entries I actually - * need; I never do a lookup on a variable input of zero and the biggest - * exponents I'll ever see are 254 (variable) and 237 (constant), so they'll - * never sum to more than 491. I'm repeating part of the exp_to_poly table - * so that I don't have to do mod-255 reduction in the exponent arithmetic. - * Since I know my constant operands are never zero, I only have to worry - * about zero values in the variable operand, and I do it with a simple - * conditional branch.

operations in GF(2^8) represented as GF(2)[x]/w(x) where + * w(x)=x^8+x^6+x^3+x^2+1. We care about doing that because it's part of the + * definition of the RS matrix in the key schedule. Elements of that field + * are polynomials of degree not greater than 7 and all coefficients 0 or 1, + * which can be represented naturally by bytes (just substitute x=2). In that + * form, GF(2^8) addition is the same as bitwise XOR, but GF(2^8) + * multiplication is inefficient without hardware support. To multiply + * faster, I make use of the fact x is a generator for the nonzero elements, + * so that every element p of GF(2)[x]/w(x) is either 0 or equal to (x)^n for + * some n in 0..254. Note that that caret is exponentiation in GF(2^8), + * *not* polynomial notation. So if I want to compute pq where p and q are + * in GF(2^8), I can just say: + * 1. if p=0 or q=0 then pq=0 + * 2. otherwise, find m and n such that p=x^m and q=x^n + * 3. pq=(x^m)(x^n)=x^(m+n), so add m and n and find pq + * The translations in steps 2 and 3 are looked up in the tables + * poly_to_exp (for step 2) and exp_to_poly (for step 3). To see this + * in action, look at the CALC_S macro. As additional wrinkles, note that + * one of my operands is always a constant, so the poly_to_exp lookup on it + * is done in advance; I included the original values in the comments so + * readers can have some chance of recognizing that this *is* the RS matrix + * from the Twofish paper.

It allows the write to selected bits of this register without altering the bits that are not selected. Command style registers are divided into 4 bytes that can be written independently. Higher order bit of each byte is the value bit that specifies the value that will be written into the selected bits of register. eg., if the value 10011010b is written into the least significant byte of a command style register, bits 1,3 and 4 of the register will be set to 1, and the other bits will not be altered. If the value 00011010b is written into the same byte, bits 1,3 and 4 will be cleared to 0 and the other bits will not be altered. @@ -122,8 +122,8 @@ typedef enum { ASF_INIT_DONE = (1 << 1), ASF_INIT_PRESENT = (1 << 0), -}STAT_ASF_BITS;
