This patch fixes CVE-2021-3518. The fix for the CVE is the
following 3 lines in 1098c30a:
- (cur->children->type != XML_ENTITY_DECL) &&
- (cur->children->type != XML_XINCLUDE_START) &&
- (cur->children->type != XML_XINCLUDE_END)) {
+ ((cur->type == XML_DOCUMENT_NODE) ||
+ (cur->type == XML_ELEMENT_NODE))) {
This relies on an updated version of xinclude.c from upstream which
also adds several new tests. Those changes are brought in first so
that the CVE patch can be applied cleanly.
The first patch updates xinclude.c and adds the new tests from
upstream, and the second applies the fix for the CVE.

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.
