* SYSAPPEND: Fix space strippingDany St-Amant2015-01-051-1/+1
| | | | | | | | The description of SYSAPPEND for the DMI information states that the spaces are replaced by underscores, but this replacement does not occur in 6.03. Signed-off-by: Dany St-Amant <dany.ephemeral.2014@icloud.com> Signed-off-by: Gene Cumm <gene.cumm@gmail.com>
* build: sort sources to build in a more deterministic wayPhilippe Coval2015-01-051-5/+5
| | | | | | | | | | | | | | | | | It has been observed that binaries contents are depending on the order of linked objects. This order is caused by GNU make's wildcard function and the position of sources on filesystem. This change tries to prevent this kind of randomness. Also consider building using -j1 flag to make it even more reproductible.

* core, pxe: Don't push on one stack and pop from the other in pxenvsyslinux-6.03-pre19H. Peter Anvin2014-07-291-0/+4
| | | | | | | | | | | | | | When saving/restoring the flags around the stack switch test, we cannot leave live data on the stack *across* the stack switch that we are going to use on the other side (unlike the "big" stack frame which we only use once we are back on the original stack.) Use register BP, which is not live at either point, as a temporary holding place for the flags from the stack.

* pxe: Re-add support for embedded DHCP optionssyslinux-6.03-pre15H. Peter Anvin2014-06-164-3/+23
| | | | | | | | | | Fix the support for embedded DHCP options. Although we were diligently saving them away, we never actually parsed them. This fixes embedded options for BIOS only -- for EFI we need to modify the encoding scheme so that it can fit inside an EFI PECOFF image. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Make symbols defined in linker script HIDDENH. Peter Anvin2014-06-101-149/+149

* ntfs: fix incorrect file->offset usage in ntfs_readdirAndy Alex2014-06-021-6/+4
| | | | | | | | | | | | | file->offset is used to store position in index root between ntfs_readdir calls. Previously, pointer to buffer was stored in this field. However this buffer is reallocated and read each ntfs_readdir call so the pointer may become incorrect. Now offset in index root rather than pointer is stored in this field.

* cache, btrfs: Provide a general cached read routineH. Peter Anvin2014-05-263-34/+41

* btrfs: Fix stack smash with node size > 4Ksyslinux-6.03-pre12H. Peter Anvin2014-05-262-41/+62
| | | | | | | | | | | Newer btrfs has a node size of more than 4K. Make sure we have a buffer big enough to hold a node -- instead of allocating it on the stack, allocate it at startup time. While changing this code, remove a completely unnecessary arbitrary 64-bit divide. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* core: Avoid initializing the cache more than onceRaphael S. Carvalho2014-04-034-2/+7

| | | | | | | | | | | | | | | | | | | | Remove the last bits of the comapi interfaces completely. This does not install stub handlers for the INT 20-3Fh handlers, as we don't support loading old COMBOOT/COM32/COM32R images anymore. We could put those back if we really need them. Signed-off-by: H.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attached is a patch which switches susp_rr.c from reading the big-endian ISO 9660 and SUSP numbers to reading the little-endian ones. Tested within libisofs on my collection of ISO images. [ hpa: more mastering programs are known which botch the bigendian information than the littleendian information, so most systems only read the littleendian info regardless of the native byte order. ]
| * | iso9660: Avoid arbitrarily large malloc()sThomas Schmitt2013-04-021-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After explaining the slightly wasteful usage of malloc()/memcpy() with multi-block CE entries, i noticed that i did not install a safety cap on the malloc size. I could not challenge this in practice but only by gdb manipulation. My most CE-happy test image has 3 occasions of multi-block CE. All three only span over 2 blocks each.
| * | iso9660: Add support for Rock Ridge filenamesThomas Schmitt2013-03-314-4/+659
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for parsing SUSP and RRIP records, and support for Rock Ridge filename extensions, thus avoiding the filename limitations (length and character set) of plain iso9660. This will be a part of using UTF-8 for filenames and console. [ hpa: manually rebased to the elflink branch ]

| | | | | | | | | | | | | | | | | | | | | | | | On some code, the intcall 0x15 was missing when playing with 0x8800 making code useless. That's not a big deal since e820 or e801 shall be provided by host but anyway, let's fix it ;)

Having unclean inreg could trigger bad behaviors on some hosts. This patch is about adding memset() calls prior any intcall() : - some intcall didn't had any memset at all - some successive intcall() calls didn't memset inreg in between calls
