Correct base's type to match its initialization from prot_mode_base and passage to syslinux_memmap_find(). Tested with extlinux.

Hi, in syslinux-386, I think I've found a problem in com32/lib/syslinux/load_linux.c that leads to cmdline being truncated unnecessarily when e.g. linux.c32 is used. The patch below fixes the problem for me. But I don't know, whether the patch is safe in all cases. I tried to reproduce the logic found in runkernel.inc, but I might have missed something. So, feel free to tell me

If the kernel is relocatable and the protected mode code will not fit in the initially determined location, that code will be moved to the next available location. However, beginning with commit 8f470e7b, the code is moved to the initially determined location instead of the next available location because prot_mode_base is no longer updated to the correct location. Since whdr->code32_start is

Impact: None. The end of memory needs to be page aligned: if the initrd expands beyond it, Linux kernels won't be able to access the last few bytes.

Some kernel images use the Linux kernel boot protocol and header structure, but do not actually have any protected-mode code. For instance, grub's 1024-byte lnxboot.img consists of 1024 real-mode bytes and 0 protected-mode bytes; you can concatenate it with a full grub core.img to produce a self-contained bootable kernel, but you can also use it standalone as the kernel with the core.img

These patches fix a few compiler warnings.

PXELINUX has stopped recognizing the keeppxe option on the kernel command line. Here is a patch to make it work again. With COM32, it is no longer possible to use preprocessor directives to determine the SYSLINUX variant. The code inside the #if will never be compiled. So, I changed it to use syslinux_filesystem() to determine the variant. Also, I moved the relevant code from

Hi, back in February, Scot Doyle proposed two patches: http://www.syslinux.org/archives/2015-February/023209.html http://www.syslinux.org/archives/2015-February/023179.html Since then, the bug fixed by those patches has been identified in Ubuntu, Debian and Tails: https://bugs.launchpad.net/ubuntu/+source/syslinux/+bug/1429323 https://bugs.debian.org/780765

gfxboot uses those three calls, but currently doesn't really handle returns from them. syslinux_boot_linux (lib/syslinux/load_linux.c) can return ("bail" label). syslinux_local_boot (lib/syslinux/localboot.c) has a comment which says "returns only on failure". The documentation for "Local boot" in doc/comboot.txt says "Does not return". Which is correct?
