Menglong Dong 37653a0b8a net: ip: make fib_validate_source() support drop reasons ... In this commit, we make fib_validate_source() and __fib_validate_source() return -reason instead of errno on error. The return value of fib_validate_source can be -errno, 0, and 1. It's hard to make fib_validate_source() return drop reasons directly. The fib_validate_source() will return 1 if the scope of the source(revert) route is HOST. And the __mkroute_input() will mark the skb with IPSKB_DOREDIRECT in this case (combine with some other conditions). And then, a REDIRECT ICMP will be sent in ip_forward() if this flag exists. We can't pass this information to __mkroute_input if we make fib_validate_source() return drop reasons. Therefore, we introduce the wrapper fib_validate_source_reason() for fib_validate_source(), which will return the drop reasons on error. In the origin logic, LINUX_MIB_IPRPFILTER will be counted if fib_validate_source() return -EXDEV. And now, we need to adjust it by checking "reason == SKB_DROP_REASON_IP_RPFILTER". However, this will take effect only after the patch "net: ip: make ip_route_input_noref() return drop reasons", as we can't pass the drop reasons from fib_validate_source() to ip_rcv_finish_core() in this patch. Following new drop reasons are added in this patch: SKB_DROP_REASON_IP_LOCAL_SOURCE SKB_DROP_REASON_IP_INVALID_SOURCE Signed-off-by: Menglong Dong <dongml2@chinatelecom.cn> Signed-off-by: Paolo Abeni <pabeni@redhat.com>		2024-11-12 11:24:50 +01:00
