* [jme] Fix refill behaviorGuo-Fu Tseng2010-06-131-7/+13
| | | | | | | | | | | After changing the driver to refill after feed, if any error occurs a non-contiguous empty buffer will be introduced in the ring due to my reuse-buffer-when-error implementation.

| | | | | | | | | | | | | | | This removes the need for inline safety wrappers, marginally reducing the size penalty of weak functions, and works around an apparent binutils bug that causes undefined weak symbols to not actually be NULL when compiling with -fPIE (as EFI builds do). A bug in versions of binutils prior to 2.16 (released in 2005) will cause same-file weak definitions to not work with those toolchains.

* [efi] Verify object format support in elf2efi.cGeoff Lywood2010-05-271-2/+3

* [dhcp] Honor PXEBS_SKIP option in discovery controlJoshua Oreman2010-05-271-2/+26
| | | | | | | | | | | | | | | | It is permissible for a DHCP packet containing PXE options to specify only "discovery control", instead of the more typical boot menu + prompt options. This is the strategy used by older versions of dnsmasq; by specifying the discovery control as PXEBS_SKIP, they cause vendor PXE ROMs to ignore boot server discovery and just use the filename and next-server options in the initial (Proxy)DHCP packet. Modify iPXE to accept this behavior, to be more compatible with the Intel firmware.

* [wpa] Remove PMKID checkingJoshua Oreman2010-05-271-64/+0Star
| | | | | | | | | | | | PMKID checking is an additional pre-check that helps detect invalid passphrases before going through the full handshaking procedure. It takes up some amount of code size, and is not necessary from a security perspective. It also is implemented improperly by some routers, which was causing iPXE to give spurious authentication errors. Remove it for these reasons.

* [tcp] Update received sequence number before delivering received dataMichael Brown2010-05-221-8/+10
| | | | | | | | | | | | | iPXE currently updates the TCP sequence number after delivering the data to the application via xfer_deliver_iob(). If the application responds to the received data by transmitting more data, this would result in a stale ACK number appearing in the transmitted packet, which potentially causes retransmissions and also gives the undesirable appearance of violating causality (by sending a response to a message that we claim not to have yet received).

* [pxe] Treat PXENV_RESTART_TFTP as unreturnableMichael Brown2010-05-213-7/+17
| | | | | | | | | | | | | | | | | | | | | | | Microsoft WDS can end up calling PXENV_RESTART_TFTP to execute a second-stage NBP which then exits. Specifically, wdsnbp.com uses PXENV_RESTART_TFTP to execute pxeboot.com, which will exit if the user does not press F12. iPXE currently treats PXENV_RESTART_TFTP as a normal PXE API call, and so attempts to return to wdsnbp.com, which has just been vaporised by pxeboot.com. Use rmsetjmp/rmlongjmp to preserve the stack state as of the initial NBP execution, and to restore this state immediately prior to executing the NBP loaded via PXENV_RESTART_TFTP. This matches the behaviour in the PXE spec (which says that "if TFTP is restarted, control is never returned to the caller"), and allows pxeboot.com to exit relatively cleanly back to iPXE. As with all usage of setjmp/longjmp, there may be subtle corner case bugs due to not gracefully unwinding any state accumulated by the time of the longjmp call, but this seems to be the only viable way to provide the specified behaviour.

* [romprefix] Add .mrom format, allowing loading of large ROMsMichael Brown2010-04-255-9/+518
| | | | | | | | | | | | | | | | | | | | | Add an infrastructure allowing the prefix to provide an open_payload() method for obtaining out-of-band access to the whole iPXE image. Add a mechanism within this infrastructure that allows raw access to the expansion ROM BAR by temporarily borrowing an address from a suitable memory BAR on the same PCI card. For cards that have a memory BAR that is at least as large as their expansion ROM BAR, this allows large iPXE ROMs to be supported even on systems where PMM fails, or where option ROM space pressure makes it impossible to use PMM shrinking. The BIOS sees only a stub ROM of approximately 3kB in size; the remainder (which can be well over 64kB) is loaded only at the time iPXE is invoked. As a nice side-effect, an iPXE .mrom image will continue to work even if its PMM-allocated areas are overwritten between initialisation and invocation. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [romprefix] Inhibit the use of relocation during POSTMichael Brown2010-04-253-6/+25
| | | | | | | | | | | | | | | It is common for system memory maps to be grotesquely unreliable during POST. Many sanity checks have been added to the memory map reading code, but these do not catch all problems. Skip relocation entirely if called during POST. This should avoid the problems typically encountered, at the cost of slightly disrupting the memory map of an operating system booted via iPXE when iPXE was entered during POST. Since this is a very rare special case (used, for example, when reflashing an experimental ROM that would otherwise prevent the system from completing POST), this is an acceptable cost.
