[PATCH 1/2] ldlinux: fix stack overflow when running COM32 modules
From: Sylvain Gault <sylvain.gault at gmail.com>
When a COM32 module exits, the functions never return and a new call to
ldlinux_enter_command is made. This could fill the stack and overflow on
some data present in memory.
This patch use setjmp/longjmp to return to the main function and restart
from there when a COM32 module exits.

[PATCH 0/2] Stack overflows when running commands
From: Sylvain Gault <sylvain.gault at gmail.com>
Hello there,
I propose 2 patches that fix two possible stack overflows either when running a
COM32 module or when loading a new config file.
I didn't find a better way to do this than to use the infamous setjmp/longjmp
functions to restore the stack to a previous state. This makes the logic a bit
more complex, but the behavior is not

[GIT PULL] elflink fixes
Hi Peter,
The main part of this pull request includes commits that try to replace
as many __intcall() invocations as possible. Some remain, but not many
(and eventually they'll be gone too). There's also a patch to make
better use of ld's --as-needed option and various other bug
fixes/cleanups.

[GIT PULL] elflink fixes
Peter,
Paulo reported some problems with his config files under ISOLINUX and
PXELINUX - basically TIMEOUT and TOTALTIMEOUT were broken. The patches
I've pushed to the elflink branch fix this and also fix parsing of the
ALLOWOPTIONS config directive.

[PATCH 0/9] elflink fixes
From: Matt Fleming <matt.fleming at intel.com>
Here are the patches that I've got queued up based on the very helpful
feedback I received from people testing Syslinux 5.00-pre9. Unless
anyone has any concerns these will make it into Syslinux 5.00-pre10.

SYSAPPEND not replacing spaces
Hello,
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. There's small bug present in triplicata in com32/elflink/ldlinux/readconfig.c:copy_sysappend_string(), com32/menu/readconfig.c:copy_sysappend_string(), and core/sysappend.c:copy_and_mangle() prevent proper replacement of spaces by

boot... round 2
To remind you once again.
ISOLINUX >= 6.00 built with GCC >= 5.0.0 causes a broken boot.
This relates specifically to the use of the vesamenu.c32,
menu.c32 works without problemos.
This "code" is already in 6.03, therefore this is not a fix for it!

[PATCH 0/4] some fixes on elflink branch
This is a small set of patches for elflink branch based on

patches on my git tree.

Syslinux 6.01 released
OK, 6.01 is now out.
The main intention of this release was to fix the terrible bug in
Syslinux 6.00 which made it impossible to boot kernels from BIOS. This
resulted in a way shorter than usual release cycle, and it does mean
that there are some bugs that have been reported that haven't yet been
fixed. Shortlog appended below.
Thanks to everyone who helped test things out.

[GIT PULL] elflink warning fixes and auto extension support
Hi,
I just pushed out changes that fix pretty much all the compiler build
warnings on the elflink branch. Also, I've added "auto extension"
support so that if the user doesn't type the file name extension it will
automatically be looked up, e.g. now typing "ls" will execute "ls.c32".

To be clear: core treats the value as always hexidecimal while simple
menu treats it as decimal unless a 0x prefix is

[GIT PULL] elflink compiler warning fixes
Hi,
These patches fix some compiler warnings in ldlinux and elflink. I've
tried to split the patches out so that they only change one file or one
type of problem at once. So, if they do inadvertently introduce any
bugs it should at least be easy to bisect to a smallish commit.
