| check_stack_read | |
| check_ptr_to_btf_access | |
| check_mem_access | heck whether memory at (regno + off) is accessible for t = (read | write)* if t==write, value_regno is a register which value is stored into memory* if t==read, value_regno is a register which will receive the value from memory* if t==write && |
| __clear_all_pkt_pointers | Packet data might have moved, any old PTR_TO_PACKET[_META,_END]* are now invalid, so turn them into unknown SCALAR_VALUE. |
| release_reg_references | |
| check_helper_call | |
| adjust_scalar_min_max_vals | WARNING: This function does calculations on 64-bit values, but the actual* execution may occur on 32-bit values. Therefore, things like bitshifts* need extra checks in the 32-bit case. |
| adjust_reg_min_max_vals | Handles ALU ops other than BPF_END, BPF_NEG and BPF_MOV: computes new min/max* and var_off. |
| check_alu_op | heck validity of 32-bit and 64-bit arithmetic operations |
| check_ld_abs | verify safety of LD_ABS|LD_IND instructions:* - they can only appear in the programs where ctx == skb* - since they are wrappers of function calls, they scratch R1-R5 registers,* preserve R6-R9, and store return value into R0* Implicit input:* ctx == skb |
