[Qemu-devel] [PULL 18/18] User mode support for Linux ELF files with no section header

[riku . voipio]

From: Craig Heffner <address@hidden>

In user mode Linux, Qemu currently refuses to load ELF files that do not
contain section headers (ehdr->e_shentsize == 0). Since section headers are not
required in order to load an ELF file, simply removing the e_shentsize check in
elf_check_ehdr() allows ELF binaries with no section headers to be run properly
in user mode:
