* extlinux: add ext4 support to the installersyslinux-4.00-pre1H. Peter Anvin2009-08-071-4/+5
| | | | | | | The filesystem code now supports ext4, so support it in the installer as well. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Makefile: add back the gpxe directoryH. Peter Anvin2009-08-071-1/+1
| | | | | | Add the gpxe directory back into the build. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| * extlinux: handle more than one sector of sector pointersH. Peter Anvin2009-07-161-5/+12
| | | | | | | | | | | | | | | | Fix the extlinux installer so we can handle more than one sector of sector pointers. This code should be merged with the equivalent code in the syslinux installer. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
| * dos: add pointer to PE header in binaryH. Peter Anvin2009-07-101-0/+15
| | | | | | | | | | | | | | Explicitly add the pointer to the PE header in the binary. That way we might be eventually able to create a merged DOS/Win32 binary. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
| * com32: add openmem.o to the MakefileH. Peter Anvin2009-07-091-0/+1
| | | | | | | | | | | | | | We need openmem.o in the Makefile if it's actually supposed to get built... Signed-off-by: H. Peter Anvin <hpa@zytor.com>
| * Add openmem() function to read from memory as if it were a fileH. Peter Anvin2009-07-094-9/+70
| | | | | | | | | | | | | | | | Reading from memory as if it were a file is pretty easy... we just treat it as a really big block buffer and tell the file layer that we already closed the underlying handle. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
| * core: include exported symbol informationH. Peter Anvin2009-07-093-3/+27
| | | | | | | | | | | | | | Extract symbol table information to be exported to modules. This is a really hacky way of doing it, so replace it later. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
| * syslinux.ld: add support for .ctors and .dtorsH. Peter Anvin2009-07-081-2/+22
| | | | | | | | | | | | | | We're going to need at least constructors when we start linking in com32 library code in a serious way. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | Update mdiskchk and add a Makefile. Note that since this needs OpenWatcom to compile, we still check in the binary file (which is quite small, anyway.) Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | DOS utilities aren't really "samples". Create a dedicated "dosutil" directory, and move mdiskchk there for now. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| * | MCONFIG: build GCCOPT one step at a time, don't align stackH. Peter Anvin2009-06-244-19/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some gcc options are only valid together with other gcc options, so build GCCOPT one bit at a time, and change gcc_ok to take already existing GCCOPT flags into account. This lets us build with -mpreferred-stack-boundary=2, which is only valid on 32 bits and therefore with -m32. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | NASM 2.03 or higher can generate DWARF debugging info, which is also what gcc produces. Mixing debugging info seems to cause a lot of problems. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | * PXELINUX: when chaining an NBP, restore *all* registersH. Peter Anvin2009-06-141-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On at least ASUS A8N-E, unless *all* registers are restored to pre-PXE status, localboot doesn't work. We were clobbering DS, ESI and EDX when chainloading an NBP, which meant that localboot wouldn't work in the chainloaded NBP. Fix this. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean up some of the constructs in com32.h, and make OFFS_VALID() take the pointer type into account for the range check -- the whole object needs to fit within the segment. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under some certain circumstances, it might not be safe to use the stack as it was set up, so use a jump instead of a call to invoke the bootstrap. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The main reason for ERROR is OACK parsing failure, so revert to using error code 8 (but a fixed text error.) Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of looking for a string of null bytes at the end of the OACK string, simply abort parsing if we run into a null byte where an option is expected; either we are seeing junk at the end of the packet, or we are hopelessly confused about how to make sense of the rest of the packet -- in either case, ignoring is the "liberal" option. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
| | | * PXELINUX: handle OACK packets with extra NULs, cleaner TFTP errorsyslinux-3.82-pre5H. Peter Anvin2009-06-082-11/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are apparently TFTP servers in the field which will send OACK packets with extra NUL bytes appended at the end. If we find an OACK packet where the only thing left at some point during processing is NULs, then just consider the packet processed. We have reported all TFTP protocol errors as "tsize required", which is definitely not true anymore. Change error code to 0 (undefined) and the error string to "TFTP error". When this code gets converted to C we'll do better. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If it can happen for CD-ROM BIOSes, it can probably happen elsewhere, too; make sure we don't leave interrupts disabled after broken INT 13h calls. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
| | | * simple menu: make ONTIMEOUT work with MENU HIDDENSergey Vlasov2009-06-042-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command invoked when no keys were pressed for the specified time (ONTIMEOUT) may be different from the menu item initially selected when the menu is displayed (DEFAULT or MENU DEFAULT). Unfortunately, this did not work together with MENU HIDDEN (which is exactly the case when having a separate ONTIMEOUT command makes the most sense).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Additional stylistic cleanups. Rename "syscall" to "intcall" (we can't call it __intcall without clashing with com32.h); use macros instead of copying variables to different places with only the type being different. Also, only change the rm/pm jump instructions when actually relocating the code. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Relocate the real-mode code before booting. This allows the target bootstrap to be loaded at an arbitrary address, not necessarily 0x7c00, and to be almost arbitrarily long. Add some initial infrastructure for other bootstrap addresses, too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the rm_args initialization (and the associated sti) to C code. Export the total size of the real-mode code to the protected-mode code. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Limit the size of the real-mode stack. This should limit the amount of memory needed for a relocated real-mode code. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
| | * | memdisk: remove hard-coded assumptions for a specific RM segmentH. Peter Anvin2009-06-073-100/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove some hard-coded assumptions about having an RM segment at a specific location. This should allow us to relocate the RM code once the PM code knows where DOS free memory ends. This in turn allows the PM code to load the boot sector almost anywhere it wants to go in low memory, as is required for 100% compliant El Torito support. Signed-off-by: H.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the requirement that CS_BASE is below 64K, based on its use in the A20 test code. This means it can now be located anywhere in high memory, but it is still a constant. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
