* [hci] Use http://ipxe.org/<errno> instead of raw error numbersMichael Brown2010-10-191-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Users tend to gloss over cryptic-looking error messages such as "Boot failed: Exec format error (Error 0x2e852001)" In particular, users tend not to report the error number, which is the single most useful piece of diagnostic information in an iPXE error message. Try replacing the "Error 0x2e852001" portion with a URL, giving "Boot failed: Exec format error (http://ipxe.org/2e852001)" in the hope that users will, upon seeing something that is recognisably a URL, try viewing it in a web browser. Such users will be greeted by a web page containing a more detailed description of the error (automatically generated from the einfo text), including links to each line of code that might generate the error, and a section for additional user-contributed notes. At the time of writing, a user who visits http://ipxe.org/2e852001 would see a note saying "This error usually indicates that the SAN disk is empty, and does not yet contain a bootable operating system." which may be more useful than "Exec format error (Error 0x2e852001)".

* [iscsi] Ensure ISID is consistent within an iSCSI sessionMichael Brown2010-10-182-1/+10
| | | | | | | | | | | | | | | | 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>
* [romprefix] Add missing FILE_LICENCE declaration to undiloader.SMichael Brown2010-10-181-0/+2

* [legal] Ignore config/local header files for licensing purposesMichael Brown2010-10-181-1/+4
| | | | | | | | | The config/local/*.h files are expected to be empty in most cases. This should not cause a licence determination to fail. Fix by ignoring config/local/*.h for licensing purposes. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [iscsi] Randomise a portion of the ISID to force new session instantiationMichael Brown2010-10-161-1/+1
| | | | | | | | | | | | | | | | When a connection to an iSCSI target is broken without gracefully closing the TCP socket, a subsequent connection attempt may fail because the target believes that we are attempting session reinstatement (see RFC3720 section 5.3.1). This has been observed using the Microsoft iSCSI target. Section 9.1.1 of RFC3720 states that initiators should use a stable ISID, however section 5.3.1 shows that the only way to explicitly request that a new session be created is to use a new ISID. Fix by randomising the "qualifier" portion of the ISID. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [fcoe] Request SPMA iff FIP advertisement indicates support for SPMAMichael Brown2010-10-151-5/+18
| | | | | | | | | | | | | | | We currently set both the FP and SP bits in our FIP FLOGI, to allow the FCF the choice of selecting either a fabric-provided or a server- provided MAC address. This complies with the FCoE specification, but has been observed to result in an FLOGI rejection from some FCFs. Fix by recording whether or not the FCF supports SPMA, and requesting only one of FPMA or SPMA in our FIP FLOGI. We choose to prefer SPMA where available, because many iPXE drivers will not be able to receive unicast packets sent to a non-default MAC address.

* [dhcp] Include session state metadata in packet tracesMichael Brown2010-10-091-0/+10
| | | | | | | | | | | | | | | | | (Ab)use the "secs" field in transmitted DHCP packets to convey metadata about the DHCP session state. In particular: bit 0 represents the receipt of a ProxyDHCPOFFER bit 1 represents the receipt of a DHCPOFFER bits 2+ represent the transmitted packet sequence number This allows some relevant information about the internal state of the DHCP session to be read out from a packet trace from a non-debug build of iPXE. It also potentially allows replies to be correlated to their requests (for servers that copy the "secs" field from request to reply). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [dhcp] Omit ProxyDHCPREQUEST if PXE options are present in ProxyDHCPOFFERMichael Brown2010-10-081-37/+67
| | | | | | | | | | | | Some ProxyDHCP implementations seem to violate the PXE specification by expecting the client to retain options from the ProxyDHCPOFFER rather than issuing a separate ProxyDHCPREQUEST. Work around such broken clients by retaining the ProxyDHCPOFFER packet, and proceeding to a ProxyDHCPREQUEST only if the ProxyDHCPOFFER does not already contain PXE options.

| | | | | | | | | | Error numbers are signed ints.
