* [undi] Assume that interrupts are not supported if IRQ=0Michael Brown2011-04-231-1/+3
| | | | | | | | | Some PXE stacks (notably old Etherboot/gPXE stacks) will claim to use the timer interrupt, rather than reporting that interrupts are not supported. Since using the timer interrupt is equivalent to polling anyway, we may as well genuinely poll these stacks. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [build] Run parserom.pl only on potential driver filesMichael Brown2011-04-101-1/+2
| | | | | | | | | | | PCI_ROM() and ISA_ROM() macros occur only within driver files. Running parserom.pl on non-driver files is therefore redundant. Skip running parserom.pl on any files outside a "drivers" directory. This reduces the time taken to generate build rules and dependencies after a "make veryclean" by around 12%.

* [cmdline] Simplify "isset" commandMichael Brown2011-04-081-10/+3Star
| | | | | | | | There is no plausible scenario I can think of in which "isset" would be used with more than one argument. Simplify the code by specifying that exactly one argument is required. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [hermon] Work around missing mport support in current BOFM implementationsMichael Brown2011-04-081-15/+39
| | | | | | | | | | | | | | | | | | | | | | | Current BOFM versions are unable to create entries with mport>1, which means that only the port 1 MAC address can be explicitly specified. Work around this by using the provided MAC address as a base address for all subsequent ports. For example, if BOFM assigns the address 00:1A:64:76:00:09 for port 1 then we will assign the addresses 00:1A:64:76:00:09 for port 1 00:1A:64:76:00:0a for port 2 Future BOFM versions that may correctly support mport will work with this scheme without modification provided that the BOFM entries are created in increasing order of mport. Since BOFM tools tend to generate entries in increasing order (of slot, port, etc), this is not an unreasonable compromise. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [build] Refuse to attempt building with the GNU gold linkerMichael Brown2011-04-051-0/+7
| | | | | | | | | | | | | | GNU gold (part of newer binutils builds) does not appear to be designed to support generic linker functionality, since its source code contains several Linux-specific hard-coded assumptions about the layout of ELF binaries. Attempting to build iPXE using GNU gold will generally cause some kind of "linker internal error". Provide an explicit error message suggesting the use of GNU ld instead.

* [tcp] Update ts_recent whenever window is advancedMichael Brown2011-04-031-9/+22
| | | | | | | | | | | | | Commit 3f442d3 ("[tcp] Record ts_recent on first received packet") failed to achieve its stated intention. Fix this (and reduce the code size) by moving the ts_recent update to tcp_rx_seq(). This is the code responsible for advancing the window, called by both tcp_rx_syn() and tcp_rx_data(), and so the window check is now redundant.

* [cmdline] Fix "isset" commandMichael Brown2011-04-011-2/+8
| | | | | | | | | | | | | | | Commit b5f5f73 ("[cmdline] Expand settings within each command-line token individually") introduced a regression into the "isset" command: it is now possible for command-line arguments to be empty strings, and so "isset" cannot simply check for a non-empty argument list. Restore previous behaviour by checking for the presence of any non-empty arguments, rather than checking for a non-empty argument list.

* [build] Avoid generating ROMs with "match-any" vendor or device IDsMichael Brown2011-03-301-0/+1
| | | | | | | | | A PCI_ROM() entry containing a vendor or device ID of PCI_ANY_ID (0xffff) indicates to pci_find_driver() that the entry's vendor or device ID should be ignored when matching against the device's vendor or device ID. It does not represent a PCI ROM that should be built. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [build] Include only one copy of each ROM in "make allroms"Michael Brown2011-03-301-4/+4
| | | | | | | | | | | | Each PCI ROM currently ends up appearing twice in the $(ROMS) list: once under its designated name (e.g. "rtl8139.rom"), once under its PCI IDs (e.g. "bin/10ec8139.rom"). Include only the latter of these in the $(ROMS) list, so that doing "make allroms" will generate only one copy of each ROM.

* [forcedeth] Never change the NVREG_TRANSMITPOLL_MAC_ADDR_REV flagMichael Brown2011-03-301-5/+0Star
| | | | | | | | | | | iPXE operates the forcedeth NIC in promiscuous mode, and never changes the unicast MAC address filter registers.

* [forcedeth] Remove software unicast MAC address filterMichael Brown2011-03-291-9/+2Star
| | | | | | | | | | | | | | | | | | | The forcedeth driver currently implements unicast MAC address filtering in software. This is almost invariably the wrong thing to do (since the network stack must already be able to cope with unwanted packets) and it breaks FCoE (which requires the card to operate in promiscuous mode). Also, the implementation is buggy: is_local_ether_addr() is used to check for a locally-assigned Ethernet address (not to check for a unicast address), and the current link-layer address is in netdev->ll_addr, not netdev->hw_addr. Fix by removing this code. Reported-by: Tal Aloni <tal.aloni.il@gmail.com> Tested-by: Tal Aloni <tal.aloni.il@gmail.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [main] Add the "scriptlet" settingMichael Brown2011-03-282-5/+27
| | | | | | | | | | | | | | | | | | | A scriptlet is a single iPXE command that can be stored in non-volatile option storage and used to override the default "autoboot" behaviour without having to reflash the iPXE image. For example, a scriptlet could contain autoboot || reboot to instruct iPXE to reboot the system if booting fails. Unlike an embedded image, the presence of a scriptlet does not inhibit the initial "Press Ctrl-B..." prompt. This allows the user to recover from setting a faulty scriptlet.

* [cmdline] Allow ";" as an unconditional command separatorMichael Brown2011-03-281-0/+14
| | | | | | | | | | | | It is currently possible to construct a sequence of commands to be executed regardless of success or failure using "|| &&" as the command separator. (The "||" captures the failure case, the blank command converts it to a success case.) Allow ";" to be used as a more visually appealing (and space-efficient) alternative.
