With the test build failure fixed (bug 1948831), the ubuntu_bpf test on J-oem-5.17 is now failing with:

 #947/u ringbuf: invalid reservation offset 1 SKIP

 Unexpected verifier log!
 EXP: dereference of modified alloc_mem ptr R1
 RES:

 Unexpected error message!

This is because the test is expecting the following error message when this test fails:
"dereference of modified alloc_mem ptr R1"

But we are using "helper wants pointer to allocated memory" from SAUCE patch 33623ca13a "UBUNTU: SAUCE: bpf: prevent helper argument PTR_TO_ALLOC_MEM to have offset other than 0" (bug 1956585)
