Merge branch 'fixes-for-stack-with-allow_ptr_leaks'
Kumar Kartikeya Dwivedi says:
====================
Fixes for stack with allow_ptr_leaks
Two fixes for usability/correctness gaps when interacting with the stack
without CAP_PERFMON (i.e. with allow_ptr_leaks = false). See the commits
for details. I've verified that the tests fail when run without the fixes.
Changelog:

v3 -> v4
v3: https://lore.kernel.org/bpf/20241202083814.1888784-1-memxor@gmail.com
* Address Andrii's comments
* Fix bug paperered over by missing CAP_NET_ADMIN in verifier_mtu
test
* Add warning when undefined CAP_ constant is specified, and fail
test
* Reorder annotations to be more clear
* Verify that fixes fail without patches again
* Add Acked-by from Andrii
v2 -> v3

* We can simply always return early when stype == STACK_INVALID
* Drop allow_ptr_leaks conditionals
* Add Eduard's __caps_unpriv patch into the series
* Convert test_verifier_mtu to use it
* Move existing tests to __caps_unpriv annotation and verifier_spill_fill.c
