[PATCH] efi: Suspicious size reduction in emalloc
From: Sylvain Gault <sylvain.gault at gmail.com> It could happen on 32 bits architecture that the memory size really allocated could be less than required. On 64 bits, allocate_pages may be called more times than needed. This closes bug #39.

[PATCH] Call ExitBootServices twice
From: Sylvain Gault <sylvain.gault at gmail.com> On some architecture, including my hardware, the function ExitBootServices may need to be called twice in order to successfully exit the boot services. As stated by the UEFI spec, the first call to ExitBootServices may perform a partial shutdown of the services. It seems that during this partial shutdown, the memory map can be modified, thus

[PATCH] efi: off-by-one in gdt allocation

[PATCH v3 3/8] OvmfPkg: define EFI_XEN_OVMF_INFO and extend XenInfo
EFI_XEN_OVMF_INFO is defined to accept configurations from hvmloader. It must match the definition on Xen side. XenInfo is extended to include necessary bits as well.

[PATCH 0/2] Fixes for gcc 5
From: Sylvain Gault <sylvain.gault at gmail.com> TL;DR: The section aligment in linker scripts messed-up the memory mapping needed for the compression / decompression to work. The bug with gcc 5 is not trivial, I'll do my best to explain it here. Basically, there are two memory mappings of the code. One in "virtual memory", and one in "load memory". The one in

[PATCH 1/1] ldlinux: Fix return pointer to local data
From: Sylvain Gault <sylvain.gault at gmail.com> The command-line parsing used to return a pointer to a local array. The code used to work by chance, but now, gcc 5 is able to detect it and return a NULL pointer instead. The buffer is now marked static. This shouldn't be a problem as only one command line can be read at a time. Signed-off-by: Sylvain Gault <sylvain.gault at

[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
