* [xfer] Implement xfer_vreopen() to properly handle redirectionsMichael Brown2009-03-3013-14/+44
| | | | | When handling a redirection event, we need to close the existing connection before opening the new connection.
* [bzimage] Support old (pre-2.00 bootloader) Linux kernel formatsMichael Brown2009-03-302-249/+235Star
| | | | | | | | | | This allows gPXE to load memtest86, which is packaged as an old kernel. Split all code that directly touches the kernel headers out into bzimage_parse_header() and bzimage_update_header(), to reduce code size and offset the cost of supporting older kernels. Total cost of this feature: 11 bytes (uncompressed).
* [build] Avoid always rebuilding bin/embedded.oMichael Brown2009-03-271-2/+2
| | | | | | | | | | | bin/embedded.o has a build dependency on bin/.embedded.list, which gets generated automatically by the Makefile. However, if the EMBEDDED_IMAGE list is empty, bin/.embedded.list will never be created, and so bin/embedded.o will be rebuilt every time due to a missing dependency. Fix by forcing bin/.embedded.list to be created even if the list is empty.

* [tables] Incorporate table data type information into table definitionMichael Brown2009-03-1326-128/+183
| | | | | | | Eliminate the potential for mismatches between table names and the table entry data type by incorporating the data type into the definition of the table, rather than specifying it explicitly in each table accessor method.
* [tables] Redefine methods for accessing linker tablesMichael Brown2009-03-1348-264/+239Star
| | | | | | | | | | | | | | | Intel's C compiler (icc) chokes on the zero-length arrays that we currently use as part of the mechanism for accessing linker table entries. Abstract away the zero-length arrays, to make a port to icc easier. Introduce macros such as for_each_table_entry() to simplify the common case of iterating over all entries in a linker table. Represent table names as #defined string constants rather than unquoted literals; this avoids visual confusion between table names and C variable or type names, and also allows us to force a compilation error in the event of incorrect table names.
* [tcp] Avoid setting PSH flag when SYN flag is setMichael Brown2009-03-101-1/+3

* [settings] Allow for autovivification of settings blocksMichael Brown2009-03-062-53/+113
| | | | | | | | | | | | | | | | | | Allow for settings blocks to be created on demand. This allows for constructions such as set defaults/filename http://bootserver/bootfile set defaults/priority 0xff dhcp net0 chain ${filename} which will boot from the DHCP-provided filename, or from "http://bootserver/bootfile" if the DHCP server does not provide a filename. (Note that "priority" gets interpreted as a signed integer, so setting "defaults/priority" to 0xff will cause the "defaults" settings block to have an effective priority of -1.)

* [infiniband] Kill off obsolete mlx_ipoib directoryMichael Brown2009-02-2529-16486/+0Star
| | | | | | This directory contains the old Etherboot implementation of IPoIB boot from Mellanox, which has long been obsoleted by gPXE's own implementation.
* [image] Allow for zero embedded imagesMichael Brown2009-02-246-20/+32
| | | | | | | | | | | | | | | | | | Having a default script containing #!gpxe autoboot can cause problems when entering commands to load and start a kernel manually; the default script image will still be present when the kernel is started and so will be treated as an initrd. It is possible to work around this by typing "imgfree" before any other commands, but this is counter-intuitive. Fix by allowing the embedded image list to be empty (in which case we just call autoboot()), and making this the default. Reported by alkisg@gmail.com.
* [image] Added "chain" command to fetch, load, and execute imageShao Miller2009-02-241-0/+20
| | | | | | | | | | | | The "chain" command combines the functions of "imgfetch", "imgload", and "boot". chain http://etherboot.org/gtest/gtest.gpxe is equivalent to: kernel http://etherboot.org/gtest/gtest.gpxe boot
* [pxe] Set %ax to zero on entry to PXE NBPMichael Brown2009-02-231-9/+10
| | | | | | This is not strictly an entry requirement, but it does mean that a PXE NBP returning without setting %ax will appear to have returned success.
* [pxeprefix] Search for the PXE entry points through all methodsH. Peter Anvin2009-02-231-42/+105
| | | | | | | Search for the PXE entry points (via the !PXE or PXENV+ structures) through all known combinations of search methods. Furthermore, if we find a PXENV+ structure, attempt to use it to find the !PXE structure if at all possible.
* [iscsi] Include credentials in iBFT only if used during iSCSI loginMichael Brown2009-02-203-17/+73
| | | | | | | | Avoid passing credentials in the iBFT that were available but not required for login. This works around a problem in the Microsoft iSCSI initiator, which will refuse to initiate sessions if the CHAP password is fewer than 12 characters, even if the target ends up not asking for CHAP authentication.

* [crypto] Allow creation of arbitrary CBC cipher algorithms using CBC_CIPHER()Michael Brown2009-02-193-106/+66Star

* [crypto] Change cipher_{en,de}crypt() to void functionsMichael Brown2009-02-193-50/+25Star
| | | | | | It is a programming error, not a runtime error, if we attempt to use block ciphers with an incorrect blocksize, so use an assert() rather than an error status return.
* [crypto] Split crypto_algorithm into {digest,cipher,pubkey}_algorithmMichael Brown2009-02-1816-121/+160
| | | | | | | | The various types of cryptographic algorithm are fundamentally different, and it was probably a mistake to try to handle them via a single common type. pubkey_algorithm is a placeholder type for now.
* [crypto] Move AES_convert_key() hack into axtls_aes.cMichael Brown2009-02-182-13/+25
| | | | | | Although the nature of the hack is essentially unchanged, this allows us to remove the hardcoded assumption in tls.c that the RX cipher is AES.

* [pxe] Initialize EDX on PXE NBP entry and INT 1AhH. Peter Anvin2009-02-182-8/+13
| | | | | | | | | The PXE 1.x spec specifies that on NBP entry or on return from INT 1Ah AX=5650h, EDX shall point to the physical address of the PXENV+ structure. The PXE 2.x spec drops this requirement, simply stating that EDX is clobbered. Given the principle "be conservative in what you send, liberal in what you accept", however, we should implement this anyway.
* [pxeprefix] Add .kkpxe image type and ability to return via PXE stackMichael Brown2009-02-187-39/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain combinations of PXE stack and BIOS result in a broken INT 18 call, which will leave the system displaying a "PRESS ANY KEY TO REBOOT" message instead of proceeding to the next boot device. On these systems, returning via the PXE stack is the only way to continue to the next boot device. Returning via the PXE stack works only if we haven't already blown away the PXE base code in pxeprefix.S. In most circumstances, we do want to blow away the PXE base code. Base memory is a limited resource, and it is desirable to reclaim as much as possible. When we perform an iSCSI boot, we need to place the iBFT above the 512kB mark, because otherwise it may not be detected by the loaded OS; this may not be possible if the PXE base code is still occupying that memory. Introduce a new prefix type .kkpxe which will preserve both the PXE base code and the UNDI driver (as compared to .kpxe, which preserves the UNDI driver but uninstalls the PXE base code). This prefix type can be used on systems that are known to experience the specific problem of INT 18 being broken, or in builds (such as gpxelinux.0) for which it is particularly important to know that returning to the BIOS will work.

* [comboot] Restore the real-mode stack pointer on exit from a COMBOOT imageMichael Brown2009-02-175-14/+40
| | | | | | | | | | | | | COMBOOT images use INTs to issue API calls; these end up making calls into gPXE from real mode, and so temporarily change the real-mode stack pointer. When our COMBOOT code uses a longjmp() to implement the various "exit COMBOOT image" API calls, this leaves the real-mode stack pointer stuck with its temporary value, which causes problems if we eventually try to exit out of gPXE back to the BIOS. Fix by adding rmsetjmp() and rmlongjmp() calls (analogous to sigsetjmp()/siglongjmp()); these save and restore the additional state needed for real-mode calls to function correctly.
