I am trying to add UEFI support to my existing PXE environment for kickstarting CentOS 7.0. With bios boot all is working well. I have added syslinux.efi and ldlinux.e64 from syslinux 6.03 to my tftp server and altered my dhcp server to boot syslinux.efi. I get to my usual menu fine, the server downloads vmlinuz and initrd.img fine but then bails out with "Failed to allocate memory for

Hello Richard As discussed in the IRC channel, when merging a moderately large reg file (~35MB) to a hiv file (~118 MB); hivex generates a huge hiv file (~580 MB). These changes address that by creating a list of unallocated blocks and reassigning unused blocks. I used https://github.com/msuhanov/regf/blob/master/Windows%20registry%20file%20format%20specification.md as a reference for the

From: Sylvain Gault <sylvain.gault at gmail.com> I found something suspicious while hunting another bug a while ago. The conditions for that bug to occur seems quite hard to meet, but it's still code quality improvement. See the commit message for details.

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.
