When the code is compiled with "-fstack-protector-strong -D_FORTIFY_SOURCE=2", everytime ftpfd is asked for a non existent file, it crashes with the following error: *** buffer overflow detected ***: Aborted This seems to be a bug/feature of gcc. A bug has been open on their bugzilla, and also inetutils have been posted with the proposed patch. Without this patch, pxelinux fails to boot because it keeps asking the server for the pxelinux.cfg/00-01-02-03-04 and never jumps to /default.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
