* [parseopt] Add generic option-parsing libraryMichael Brown2010-11-212-0/+128
| | | | | | | | | | | | | | | | Command implementations tend to include a substantial amount of common boilerplate code revolving around the parsing of command-line options and arguments. This increases the size cost of each command. Introduce an option-parsing library that abstracts out the common operations involved in command implementations. This enables the size of each individual command to be reduced, and also enhances consistency between commands. Total size of the library is 704 bytes, to be amortised across all command implementations. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [netdevice] Allow per-device receive queue processing to be frozenMichael Brown2010-11-201-2/+37
| | | | | | | | | | | | | | Several use cases (e.g. the UNDI API and the EFI SNP API) require access to the raw network device receive queue, and so currently use manual calls to netdev_poll() on a specific network device in order to prevent received packets from being processed by the network stack. As an alternative, provide a flag that allows receive queue processing to be frozen on a per-device basis. When receive queue processing is frozen, packets will be enqueued as normal, but will not be automatically dequeued and passed up the network stack. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [list] Add list_first_entry()Michael Brown2010-11-081-0/+13
| | | | | | | | | There are several points in the iPXE codebase where list_for_each_entry() is (ab)used to extract only the first entry from a list. Add a macro list_first_entry() to make this code easier to read. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [autoboot] Introduce "skip-san-boot" optionDave Hansen2010-10-221-2/+10
| | | | | | | | | | | | | For some install-to-SAN scenarios, the OS needs to be able to reboot to reread the partition table. On this second boot attempt, the SAN disk will not be empty and so iPXE will attempt to boot from it, rather than falling back to the OS' installation media. Work around this problem by introducing the "skip-san-boot" option, similar in spirit to "keep-san". Modified-by: Michael Brown <mcb30@ipxe.org> Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [scsi] Wait for a successful TEST UNIT READY commandMichael Brown2010-10-191-0/+12
| | | | | | | | | | | | | Some SCSI targets (observed with an EMC CLARiiON Fibre Channel target) will not respond to commands correctly until a TEST UNIT READY has been issued. In particular, a READ CAPACITY (10) command will return with a success status, but no capacity data. Fix by issuing a TEST UNIT READY command automatically, and delaying further SCSI commands until the TEST UNIT READY has succeeded.

* [iscsi] Ensure ISID is consistent within an iSCSI sessionMichael Brown2010-10-181-0/+6
| | | | | | | | | | | | | | | | Commit 5f4ab0d ("[iscsi] Randomise a portion of the ISID to force new session instantiation") introduced a regression by randomising the ISID on each call to iscsi_start_login(), which may be called more than once per connection, rather than on each call to iscsi_open_connection(), which is guaranteed to be called only once per connection. This is incorrect behaviour that causes our connection to be rejected by some iSCSI targets (observed with a COMSTAR target under OpenSolaris). Fix by generating the ISID in iscsi_open_connection(), and storing the randomised ISID as part of the session state. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [netdevice] Pass both link-layer addresses in net_tx() and net_rx()Michael Brown2010-10-072-5/+9
| | | | | | | | | FCoE requires the use of fabric-provided MAC addresses, which breaks the assumption that the net device's MAC address is implicitly the source address for net_tx() and the (unicast) destination address for net_rx(). Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [int13] Add infrastructure to support EDD version 4.0Michael Brown2010-09-223-0/+200
| | | | | | | | | | | | | | | | | | | | | | Support the extensions mandated by EDD 4.0, including: o the ability to specify a flat physical address in a disk address packet, o the ability to specify a sector count greater than 127 in a disk address packet, o support for all functions within the Fixed Disk Access and EDD Support subsets, o the ability to describe a device using EDD Device Path Information. This implementation is based on draft revision 3 of the EDD 4.0 specification, with reference to the EDD 3.0 specification. It is possible that this implementation may need to change in order to conform to the final published EDD 4.0 specification. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [infiniband] Add node GUID as distinct from the first port GUIDMichael Brown2010-09-161-3/+4
| | | | | | | | | | | | | | | iPXE currently uses the first port's port GUID as the node GUID, rather than using the (possibly distinct) real node GUID. This can confuse opensm during the handover to a loaded OS: it thinks the port already belongs to a different node and so discards our port information with a warning message about duplicate ports. Everything is picked up correctly on the second subnet sweep, after opensm has established that the "old" node no longer exists, but this can delay link-up unnecessarily by several seconds. Fix by using the real node GUID. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [infiniband] Always call ib_link_state_changed() in ib_smc_update()Michael Brown2010-09-161-2/+2
| | | | | | | | | | | | | | ib_smc_update() potentially updates the Infiniband port state, and so should almost always be followed by a call to ib_link_state_changed(). The one exception is the call made to ib_smc_update() before the device is registered. Fix by removing explicit calls to ib_link_state_changed() from drivers using ib_smc_update(), including a call to ib_link_state_changed() within ib_smc_update(), and creating a separate ib_smc_init() for use prior to device registration.

* [block] Replace gPXE block-device API with an iPXE asynchronous interfaceMichael Brown2010-09-1413-409/+681
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The block device interface used in gPXE predates the invention of even the old gPXE data-transfer interface, let alone the current iPXE generic asynchronous interface mechanism. Bring this old code up to date, with the following benefits: o Block device commands can be cancelled by the requestor. The INT 13 layer uses this to provide a global timeout on all INT 13 calls, with the result that an unexpected passive failure mode (such as an iSCSI target ACKing the request but never sending a response) will lead to a timeout that gets reported back to the INT 13 user, rather than simply freezing the system. o INT 13,00 (reset drive) is now able to reset the underlying block device. INT 13 users, such as DOS, that use INT 13,00 as a method for error recovery now have a chance of recovering. o All block device commands are tagged, with a numerical tag that will show up in debugging output and in packet captures; this will allow easier interpretation of bug reports that include both sources of information. o The extremely ugly hacks used to generate the boot firmware tables have been eradicated and replaced with a generic acpi_describe() method (exploiting the ability of iPXE interfaces to pass through methods to an underlying interface). The ACPI tables are now built in a shared data block within .bss16, rather than each requiring dedicated space in .data16. o The architecture-independent concept of a SAN device has been exposed to the iPXE core through the sanboot API, which provides calls to hook, unhook, boot, and describe SAN devices. This allows for much more flexible usage patterns (such as hooking an empty SAN device and then running an OS installer via TFTP). Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [xfer] Generalise metadata "whence" field to "flags" fieldMichael Brown2010-09-031-25/+16Star
| | | | | | | | | | | | | iPXE has never supported SEEK_END; the usage of "whence" offers only the options of SEEK_SET and SEEK_CUR and so is effectively a boolean flag. Further flags will be required to support additional metadata required by the Fibre Channel network model, so repurpose the "whence" field as a generic "flags" field. xfer_seek() has always been used with SEEK_SET, so remove the "whence" field altogether from its argument list.
