So if b0 +of the it_present member of ieee80211_radiotap_header is set, it means that +the header for argument index 0 (IEEE80211_RADIOTAP_TSFT) is present in the +argument area. + + < 8-byte ieee80211_radiotap_header > + [ <possible argument bitmap extensions ... > ] + [ <argument> ... ] + +At the moment there are only 13 possible argument indexes defined, but in case +we run out of space in the u32 it_present member, it is defined that b31 set +indicates that there is another u32 bitmap following (shown as "possible +argument bitmap extensions..." above), and the start of the arguments is moved +forward 4 bytes each time. + +Note also that the it_len member __le16 is set to the total number of bytes +covered by the ieee80211_radiotap_header and any arguments following. + + +Requirements for arguments +-------------------------- + +After the fixed part of the header, the arguments follow for each argument +index whose matching bit is set in the it_present member of +ieee80211_radiotap_header. + + - the arguments are all stored little-endian! + + - the argument payload for a given argument index has a fixed size. So + IEEE80211_RADIOTAP_TSFT being present always indicates an 8-byte argument is + present. See the comments in ./include/net/ieee80211_radiotap.h for a nice + breakdown of all the argument sizes + + - the arguments must be aligned to a boundary of the argument size using + padding. So a u16 argument must start on the next u16 boundary if it isn't + already on one, a u32 must start on the next u32 boundary and so on. + + - "alignment" is relative to the start of the ieee80211_radiotap_header, ie, + the first byte of the radiotap header. The absolute alignment of that first + byte isn't defined. So even if the whole radiotap header is starting at, eg, + address 0x00000003, still the first byte of the radiotap header is treated as + 0 for alignment purposes. + + - the above point that there may be no absolute alignment for multibyte + entities in the fixed radiotap header or the argument region means that you + have to take special evasive action when trying to access these multibyte + entities. Some arches like Blackfin cannot deal with an attempt to + dereference, eg, a u16 pointer that is pointing to an odd address. Instead + you have to use a kernel API get_unaligned() to dereference the pointer, + which will do it bytewise on the arches that require that. + + - The arguments for a given argument index can be a compound of multiple types + together. For example IEEE80211_RADIOTAP_CHANNEL has an argument payload + consisting of two u16s of total length 4. When this happens, the padding + rule is applied dealing with a u16, NOT dealing with a 4-byte single entity. + + +Example valid radiotap header +----------------------------- + + 0x00, 0x00, // <-- radiotap version + pad byte + 0x0b, 0x00, // <- radiotap header length + 0x04, 0x0c, 0x00, 0x00, // <-- bitmap + 0x6c, // <-- rate (in 500kHz units) + 0x0c, //<-- tx power + 0x01 //<-- antenna + + +Using the Radiotap Parser +------------------------- + +If you are having to parse a radiotap struct, you can radically simplify the +job by using the radiotap parser that lives in net/wireless/radiotap.c and has +its prototypes available in include/net/cfg80211.h.

Using the N_Port Id + Virtualization (NPIV) mechanism, a point-to-point connection to a Fabric + can be assigned more than 1 N_Port_ID. Each N_Port_ID appears as a + separate port to other endpoints on the fabric, even though it shares one + physical link to the switch for communication. Each N_Port_ID can have a + unique view of the fabric based on fabric zoning and array lun-masking + (just like a normal non-NPIV adapter). Using the Virtual Fabric (VF) + mechanism, adding a fabric header to each frame allows the port to + interact with the Fabric Port to join multiple fabrics. The port will + obtain an N_Port_ID on each fabric it joins. Each fabric will have its + own unique view of endpoints and configuration parameters. NPIV may be + used together with VF so that the port can obtain multiple N_Port_IDs + on each virtual fabric. + + The FC transport is now recognizing a new object - a vport. A vport is + an entity that has a world-wide unique World Wide Port Name (wwpn) and + World Wide Node Name (wwnn). The transport also allows for the FC4's to + be specified for the vport, with FCP_Initiator being the primary role + expected. Once instantiated by one of the above methods, it will have a + distinct N_Port_ID and view of fabric endpoints and storage entities. + The fc_host associated with the physical adapter will export the ability + to create vports. The transport will create the vport object within the + Linux device tree, and instruct the fc_host's driver to instantiate the + virtual port. Typically, the driver will create a new scsi_host instance + on the vport, resulting in a unique <H,C,T,L> namespace for the vport. + Thus, whether a FC port is based on a physical port or on a virtual port, + each will appear as a unique scsi_host with its own target and lun space. + + Note: At this time, the transport is written to create only NPIV-based + vports. However, consideration was given to VF-based vports and it + should be a minor change to add support if needed. The remaining + discussion will concentrate on NPIV. + + Note: World Wide Name assignment (and uniqueness guarantees) are left + up to an administrative entity controling the vport. For example, + if vports are to be associated with virtual machines, a XEN mgmt + utility would be responsible for creating wwpn/wwnn's for the vport, + using it's own naming authority and OUI. (Note: it already does this + for virtual MAC addresses). + + +Device Trees and Vport Objects: +------------------------------- + + Today, the device tree typically contains the scsi_host object, + with rports and scsi target objects underneath it. Currently the FC + transport creates the vport object and places it under the scsi_host + object corresponding to the physical adapter. The LLDD will allocate + a new scsi_host for the vport and link it's object under the vport. + The remainder of the tree under the vports scsi_host is the same + as the non-NPIV case. The transport is written currently to easily + allow the parent of the vport to be something other than the scsi_host. + This could be used in the future to link the object onto a vm-specific + device tree. If the vport's parent is not the physical port's scsi_host, + a symbolic link to the vport object will be placed in the physical + port's scsi_host. + + Here's what to expect in the device tree : + The typical Physical Port's Scsi_Host: + /sys/devices/.../host17/ + and it has the typical decendent tree: + /sys/devices/.../host17/rport-17:0-0/target17:0:0/17:0:0:0: + and then the vport is created on the Physical Port: + /sys/devices/.../host17/vport-17:0-0 + and the vport's Scsi_Host is then created: + /sys/devices/.../host17/vport-17:0-0/host18 + and then the rest of the tree progresses, such as: + /sys/devices/.../host17/vport-17:0-0/host18/rport-18:0-0/target18:0:0/18:0:0:0: + + Here's what to expect in the sysfs tree : + scsi_hosts: + /sys/class/scsi_host/host17 physical port's scsi_host + /sys/class/scsi_host/host18 vport's scsi_host + fc_hosts: + /sys/class/fc_host/host17 physical port's fc_host + /sys/class/fc_host/host18 vport's fc_host + fc_vports: + /sys/class/fc_vports/vport-17:0-0 the vport's fc_vport + fc_rports: + /sys/class/fc_remote_ports/rport-17:0-0 rport on the physical port + /sys/class/fc_remote_ports/rport-18:0-0 rport on the vport + + +Vport Attributes: +------------------------------- + + The new fc_vport class object has the following attributes + + node_name: Read_Only + The WWNN of the vport + + port_name: Read_Only + The WWPN of the vport + + roles: Read_Only + Indicates the FC4 roles enabled on the vport. + + symbolic_name: Read_Write + A string, appended to the driver's symbolic port name string, which + is registered with the switch to identify the vport.

The following states exist: + + FC_VPORT_UNKNOWN - Unknown + An temporary state, typically set only while the vport is being + instantiated with the kernel and LLDD. + + FC_VPORT_ACTIVE - Active + The vport has been successfully been created on the FC link. + It is fully functional. + + FC_VPORT_DISABLED - Disabled + The vport instantiated, but "disabled".

This state will persist until the vport is + successfully created (state becomes FC_VPORT_ACTIVE) or it fails + (state is one of the values below).

The presense of this function will + cause the creation of the new attributes on the fc_host. As part of + the physical port completing its initialization relative to the + transport, it should set the max_npiv_vports attribute to indicate the + maximum number of vports the driver and/or adapter supports. + + +Vport Creation: + + The LLDD vport_create() syntax is: + + int vport_create(struct fc_vport *vport, bool disable) + + where: + vport: Is the newly allocated vport object + disable: If "true", the vport is to be created in a disabled stated. + If "false", the vport is to be enabled upon creation. + + When a request is made to create a new vport (via sgio/netlink, or the + vport_create fc_host attribute), the transport will validate that the LLDD + can support another vport (e.g. max_npiv_vports > npiv_vports_inuse). + If not, the create request will be failed. If space remains, the transport + will increment the vport count, create the vport object, and then call the + LLDD's vport_create() function with the newly allocated vport object. + + As mentioned above, vport creation is divided into two parts: + - Creation with the kernel and LLDD. This means all transport and + driver data structures are built up, and device objects created. + This is equivalent to a driver "attach" on an adapter, which is + independent of the adapter's link state. + - Instantiation of the vport on the FC link via ELS traffic, etc. + This is equivalent to a "link up" and successfull link initialization. + + The LLDD's vport_create() function will not synchronously wait for both + parts to be fully completed before returning. It must validate that the + infrastructure exists to support NPIV, and complete the first part of + vport creation (data structure build up) before returning. We do not + hinge vport_create() on the link-side operation mainly because: + - The link may be down. It is not a failure if it is. It simply + means the vport is in an inoperable state until the link comes up. + This is consistent with the link bouncing post vport creation. + - The vport may be created in a disabled state. + - This is consistent with a model where: the vport equates to a + FC adapter. The vport_create is synonymous with driver attachment + to the adapter, which is independent of link state. + + Note: special error codes have been defined to delineate infrastructure + failure cases for quicker resolution. + + The expected behavior for the LLDD's vport_create() function is: + - Validate Infrastructure: + - If the driver or adapter cannot support another vport, whether + due to improper firmware, (a lie about) max_npiv, or a lack of + some other resource - return VPCERR_UNSUPPORTED. + - If the driver validates the WWN's against those already active on + the adapter and detects an overlap - return VPCERR_BAD_WWN. + - If the driver detects the topology is loop, non-fabric, or the + FLOGI did not support NPIV - return VPCERR_NO_FABRIC_SUPP. + - Allocate data structures. If errors are encountered, such as out + of memory conditions, return the respective negative Exxx error code. + - If the role is FCP Initiator, the LLDD is to : + - Call scsi_host_alloc() to allocate a scsi_host for the vport. + - Call scsi_add_host(new_shost, &vport->dev) to start the scsi_host + and bind it as a child of the vport device. + - Initializes the fc_host attribute values. + - Kick of further vport state transitions based on the disable flag and + link state - and return success (zero). + + LLDD Implementers Notes: + - It is suggested that there be a different fc_function_templates for + the physical port and the virtual port. The physical port's template + would have the vport_create, vport_delete, and vport_disable functions, + while the vports would not. + - It is suggested that there be different scsi_host_templates + for the physical port and virtual port. Likely, there are driver + attributes, embedded into the scsi_host_template, that are applicable + for the physical port only (link speed, topology setting, etc). This + ensures that the attributes are applicable to the respective scsi_host. + + +Vport Disable/Enable: + + The LLDD vport_disable() syntax is: + + int vport_disable(struct fc_vport *vport, bool disable) + + where: + vport: Is vport to to be enabled or disabled + disable: If "true", the vport is to be disabled. + If "false", the vport is to be enabled. + + When a request is made to change the disabled state on a vport, the + transport will validate the request against the existing vport state. + If the request is to disable and the vport is already disabled, the + request will fail. Similarly, if the request is to enable, and the + vport is not in a disabled state, the request will fail. If the request + is valid for the vport state, the transport will call the LLDD to + change the vport's state. + + Within the LLDD, if a vport is disabled, it remains instantiated with + the kernel and LLDD, but it is not active or visible on the FC link in + any way. (see Vport Creation and the 2 part instantiation discussion). + The vport will remain in this state until it is deleted or re-enabled. + When enabling a vport, the LLDD reinstantiates the vport on the FC + link - essentially restarting the LLDD statemachine (see Vport States + above). + + +Vport Deletion: + + The LLDD vport_delete() syntax is: + + int vport_delete(struct fc_vport *vport) + + where: + vport: Is vport to delete + + When a request is made to delete a vport (via sgio/netlink, or via the + fc_host or fc_vport vport_delete attributes), the transport will call + the LLDD to terminate the vport on the FC link, and teardown all other + datastructures and references. If the LLDD completes successfully, + the transport will teardown the vport objects and complete the vport + removal. If the LLDD delete request fails, the vport object will remain, + but will be in an indeterminate state. + + Within the LLDD, the normal code paths for a scsi_host teardown should + be followed. E.g. If the vport has a FCP Initiator role, the LLDD + will call fc_remove_host() for the vports scsi_host, followed by + scsi_remove_host() and scsi_host_put() for the vports scsi_host. + + +Other: + fc_host port_type attribute: + There is a new fc_host port_type value - FC_PORTTYPE_NPIV. This value + must be set on all vport-based fc_hosts. Normally, on a physical port, + the port_type attribute would be set to NPORT, NLPORT, etc based on the + topology type and existence of the fabric. As this is not applicable to + a vport, it makes more sense to report the FC mechanism used to create + the vport. + + Driver unload: + FC drivers are required to call fc_remove_host() prior to calling + scsi_remove_host().

Minimizing the total number of commands sent (typical command latency - * including drive and bus mastering host overhead is as high as 4.5ms) - * to transfer a given amount of data. - * - * This is accomplished by placing no arbitrary limit on the number - * of scatter/gather buffers supported, since we can transfer 1K - * per scatter/gather buffer without Eric's cluster patches, - * 4K with. - * - * 2. Minimizing the number of fatal interrupts serviced, since - * fatal interrupts halt the SCSI I/O processor. Basically, - * this means offloading the practical maximum amount of processing - * to the SCSI chip. - * - * On the NCR53c810/820/720, this is accomplished by using - * interrupt-on-the-fly signals when commands complete, - * and only handling fatal errors and SDTR / WDTR messages - * in the host code. - * - * On the NCR53c710, interrupts are generated as on the NCR53c8x0, - * only the lack of a interrupt-on-the-fly facility complicates - * things. Also, SCSI ID registers and commands are - * bit fielded rather than binary encoded. - * - * On the NCR53c700 and NCR53c700-66, operations that are done via - * indirect, table mode on the more advanced chips must be - * replaced by calls through a jump table which - * acts as a surrogate for the DSA. Unfortunately, this - * will mean that we must service an interrupt for each - * disconnect/reconnect. - * - * 3. Eliminating latency by pipelining operations at the different levels. - * - * This driver allows a configurable number of commands to be enqueued - * for each target/lun combination (experimentally, I have discovered - * that two seems to work best) and will ultimately allow for - * SCSI-II tagged queuing. - * - * - * Architecture : - * This driver is built around a Linux queue of commands waiting to - * be executed, and a shared Linux/NCR array of commands to start. Commands - * are transferred to the array by the run_process_issue_queue() function - * which is called whenever a command completes. - * - * As commands are completed, the interrupt routine is triggered, - * looks for commands in the linked list of completed commands with - * valid status, removes these commands from a list of running commands, - * calls the done routine, and flags their target/luns as not busy. - * - * Due to limitations in the intelligence of the NCR chips, certain - * concessions are made. In many cases, it is easier to dynamically - * generate/fix-up code rather than calculate on the NCR at run time. - * So, code is generated or fixed up for - * - * - Handling data transfers, using a variable number of MOVE instructions - * interspersed with CALL MSG_IN, WHEN MSGIN instructions. - * - * The DATAIN and DATAOUT routines are separate, so that an incorrect - * direction can be trapped, and space isn't wasted. - * - * It may turn out that we're better off using some sort - * of table indirect instruction in a loop with a variable - * sized table on the NCR53c710 and newer chips. - * - * - Checking for reselection (NCR53c710 and better) - * - * - Handling the details of SCSI context switches (NCR53c710 and better), - * such as reprogramming appropriate synchronous parameters, - * removing the dsa structure from the NCR's queue of outstanding - * commands, etc. - * - */ - -#include <linux/module.h> - - -#include <linux/types.h> -#include <asm/setup.h> -#include <asm/dma.h> -#include <asm/io.h> -#include <asm/system.h> -#include <linux/delay.h> -#include <linux/signal.h> -#include <linux/sched.h> -#include <linux/errno.h> -#include <linux/string.h> -#include <linux/slab.h> -#include <linux/vmalloc.h> -#include <linux/mm.h> -#include <linux/ioport.h> -#include <linux/time.h> -#include <linux/blkdev.h> -#include <linux/spinlock.h> -#include <linux/interrupt.h> -#include <asm/pgtable.h> - -#ifdef CONFIG_AMIGA -#include <asm/amigahw.h> -#include <asm/amigaints.h> -#include <asm/irq.h> - -#define BIG_ENDIAN -#define NO_IO_SPACE -#endif - -#ifdef CONFIG_MVME16x -#include <asm/mvme16xhw.h> - -#define BIG_ENDIAN -#define NO_IO_SPACE -#define VALID_IDS -#endif - -#ifdef CONFIG_BVME6000 -#include <asm/bvme6000hw.h> - -#define BIG_ENDIAN -#define NO_IO_SPACE -#define VALID_IDS -#endif - -#include "scsi.h" -#include <scsi/scsi_dbg.h> -#include <scsi/scsi_host.h> -#include <scsi/scsi_transport_spi.h> -#include "53c7xx.h" -#include <linux/stat.h> -#include <linux/stddef.h> - -#ifdef NO_IO_SPACE -/* - * The following make the definitions in 53c7xx.h (write8, etc) smaller, - * we don't have separate i/o space anyway. - */ -#undef inb -#undef outb -#undef inw -#undef outw -#undef inl -#undef outl -#define inb(x) 1 -#define inw(x) 1 -#define inl(x) 1 -#define outb(x,y) 1 -#define outw(x,y) 1 -#define outl(x,y) 1 -#endif - -static int check_address (unsigned long addr, int size);

Keep track of how many - * times this has happened within a single SCSI command; if it - * gets excessive, then FATAL(). - * - * 3. Parity checking is currently disabled, and a few things should - * happen here now that we support synchronous SCSI transfers : - * 1. On soft-reset, we shoould set the EPC (Enable Parity Checking) - * and AAP (Assert SATN/ on parity error) bits in SCNTL0. - * - * 2. We should enable the parity interrupt in the SIEN0 register. - * - * 3. intr_phase_mismatch() needs to believe that message out is - * always an "acceptable" phase to have a mismatch in. If - * the old phase was MSG_IN, we should send a MESSAGE PARITY - * error. If the old phase was something else, we should send - * a INITIATOR_DETECTED_ERROR message. Note that this could - * cause a RESTORE POINTERS message; so we should handle that - * correctly first. Instead, we should probably do an - * initiator_abort. - * - * 4. MPEE bit of CTEST4 should be set so we get interrupted if - * we detect an error. - * - * - * 5. The initial code has been tested on the NCR53c810.

Need to accommodate - * different register mappings, probably scan through - * the SCRIPT code and change the non SFBR register operand - * of all MOVE instructions. - * - * It is rather worse than this actually, the 710 corrupts - * both TEMP and DSA when you do a MOVE MEMORY.

A data structure for + * queueing up work in the form of timed callbacks is also included. + * + * The group count controls how many lists are created, and thereby how finely + * the elements are grouped in time. When reaping occurs, all the elements in + * all the lists whose time has expired are deleted. + * + * To give an example of how this works in practice, consider a client that + * initialises an MRU Cache with a lifetime of ten seconds and a group count of + * five. Five internal lists will be created, each representing a two second + * period in time. When the first element is added, time zero for the data + * structure is initialised to the current time. + * + * All the elements added in the first two seconds are appended to the first + * list. Elements added in the third second go into the second list, and so on. + * If an element is accessed at any point, it is removed from its list and + * inserted at the head of the current most-recently-used list. + * + * The reaper function will have nothing to do until at least twelve seconds + * have elapsed since the first element was added. The reason for this is that + * if it were called at t=11s, there could be elements in the first list that + * have only been inactive for nine seconds, so it still does nothing. If it is + * called anywhere between t=12 and t=14 seconds, it will delete all the + * elements that remain in the first list. It's therefore possible for elements + * to remain in the data store even after they've been inactive for up to + * (t + t/g) seconds, where t is the inactive element lifetime and g is the + * number of groups. + * + * The above example assumes that the reaper function gets called at least once + * every (t/g) seconds. If it is called less frequently, unused elements will + * accumulate in the reap list until the reaper function is eventually called. + * The current implementation uses work queue callbacks to carefully time the + * reaper function calls, so this should happen rarely, if at all. + * + * From a design perspective, the primary reason for the choice of a list array + * representing discrete time intervals is that it's only practical to reap + * expired elements in groups of some appreciable size. This automatically + * introduces a granularity to element lifetimes, so there's no point storing an + * individual timeout with each element that specifies a more precise reap time. + * The bonus is a saving of sizeof(long) bytes of memory per element stored. + * + * The elements could have been stored in just one list, but an array of + * counters or pointers would need to be maintained to allow them to be divided + * up into discrete time groups. More critically, the process of touching or + * removing an element would involve walking large portions of the entire list, + * which would have a detrimental effect on performance. The additional memory + * requirement for the array of list heads is minimal. + * + * When an element is touched or deleted, it needs to be removed from its + * current list. Doubly linked lists are used to make the list maintenance + * portion of these operations O(1). Since reaper timing can be imprecise, + * inserts and lookups can occur when there are no free lists available. When + * this happens, all the elements on the LRU list need to be migrated to the end + * of the reap list. To keep the list maintenance portion of these operations + * O(1) also, list tails need to be accessible without walking the entire list. + * This is the reason why doubly linked list heads are used. + */ + +/* + * An MRU Cache is a dynamic data structure that stores its elements in a way + * that allows efficient lookups, but also groups them into discrete time + * intervals based on insertion time. This allows elements to be efficiently + * and automatically reaped after a fixed period of inactivity. + * + * When a client data pointer is stored in the MRU Cache it needs to be added to + * both the data store and to one of the lists. It must also be possible to + * access each of these entries via the other, i.e. to: + * + * a) Walk a list, removing the corresponding data store entry for each item. + * b) Look up a data store entry, then access its list entry directly. + * + * To achieve both of these goals, each entry must contain both a list entry and + * a key, in addition to the user's data pointer. Note that it's not a good + * idea to have the client embed one of these structures at the top of their own + * data structure, because inserting the same item more than once would most + * likely result in a loop in one of the lists.
