| |
Hi,
This is an even more complete Kernel IBT implementation.
Since last time (in no specific order):
- Reworked Xen and paravirt bits lots (andyhpp) - Reworked entry annotation (jpoimboe) - Renamed CONFIG symbol to CONFIG_X86_KERNEL_IBT (redgecomb) - Pinned CR4_CET (kees) - Added __noendbr to CET control functions (kees) - kexec (redgecomb) - made function-graph, kprobes and bpf not explode (rostedt) - cleanups and split ups (jpoimboe, mbenes) - reworked whole module objtool (nathanchance) - attempted and failed at making Clang go
Specifically to clang; I made clang-13 explode by rediscovering: https://reviews.llvm.org/D111108, then I tried clang-14 but it looks like ld.lld is still generating .plt entries out of thin air.
Also, I know the very first patch is somewhat controversial amonst the clang people, but I really think the current state of affairs is abysmal and this lets me at least use clang.
Patches are also available here:
git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git x86/wip.ibt
This series is on top of tip/master along with the linkage patches from Mark:

Enjoy!
