Hi ,
We are running bpf selftests on 5.4.210 kernel version and we see that test case 11 of test_align failed. Please find the below error.
selftests: bpf: test_align Test 11: pointer variable subtraction ... Failed to find match 16: R5_w=pkt(id=2,off=0,r=0,umin_value=2,umax_value=1082,var_off=(0x2; 0xfffffffc) # func#0 @0 # 0: R1=ctx(id=0,off=0,imm=0) R10=fp0 # 0: (61) r2 = *(u32 *)(r1 +76) # 1: R1=ctx(id=0,off=0,imm=0) R2_w=pkt(id=0,off=0,r=0,imm=0) R10=fp0 # 1: (61) r3 = *(u32 *)(r1 +80)
For complete errors please see the attached file. The same test case execution was successful in the 5.4.209 version , could you please let me know any known issue with the recent changes in 5.4.210 and how to fix these errors.
Can you use 'git bisect' to find the offending commit?
thanks,
