0406a91c81 selftests/bpf: Add push/pop checking for msg_verify_data in test_sockmap
[ Upstream commit 862087c3d36219ed44569666eb263efc97f00c9a ]

Add push/pop checking for msg_verify_data in test_sockmap, except for
pop/push with cork tests, in these tests the logic will be different.
1. With corking, pop/push might not be invoked in each sendmsg, it makes
the layout of the received data difficult
2. It makes it hard to calculate the total_bytes in the recvmsg
Temporarily skip the data integrity test for these cases now, added a TODO

59b13f6bb6 selftests/bpf: Fix total_bytes in msg_loop_rx in test_sockmap
[ Upstream commit 523dffccbadea0cfd65f1ff04944b864c558c4a8 ]

total_bytes in msg_loop_rx should also take push into account, otherwise
total_bytes will be a smaller value, which makes the msg_loop_rx end early.

Besides, total_bytes has already taken pop into account, so we don't need
to subtract some bytes from iov_buf in sendmsg_test. The additional
subtraction may make total_bytes a negative number, and msg_loop_rx will
just end without checking anything.

b1293e8098 selftests/bpf: Fix SENDPAGE data logic in test_sockmap
[ Upstream commit 4095031463d4e99b534d2cd82035a417295764ae ]

In the SENDPAGE test, "opt->iov_length * cnt" size of data will be sent
cnt times by sendfile.
1. In push/pop tests, they will be invoked cnt times, for the simplicity of
msg_verify_data, change chunk_sz to iov_length
2. Change iov_length in test_send_large from 1024 to 8192. We have pop test
where txmsg_start_pop is 4096. 4096 > 1024, an error will be returned.

4116625fb3 selftests/bpf: Add txmsg_pass to pull/push/pop in test_sockmap
[ Upstream commit 66c54c20408d994be34be2c070fba08472f69eee ]

Add txmsg_pass to test_txmsg_pull/push/pop. If txmsg_pass is missing,
tx_prog will be NULL, and no program will be attached to the sockmap.
As a result, pull/push/pop are never invoked.

fb0c9a0102 selftests/bpf: Fix msg_verify_data in test_sockmap
[ Upstream commit ee9b352ce4650ffc0d8ca0ac373d7c009c7e561e ]

Function msg_verify_data should have context of bytes_cnt and k instead of
assuming they are zero. Otherwise, test_sockmap with data integrity test
will report some errors. I also fix the logic related to size and index j

1/ 6  sockmap::txmsg test passthrough:FAIL
2/ 6  sockmap::txmsg test redirect:FAIL
7/12  sockmap::txmsg test apply:FAIL
10/11  sockmap::txmsg test push_data:FAIL
11/17  sockmap::txmsg test pull-data:FAIL
12/ 9  sockmap::txmsg test pop-data:FAIL
13/ 1  sockmap::txmsg test push/pop data:FAIL
...
Pass: 24 Fail: 52

After applying this patch, some of the errors are solved, but for push,
pull and pop, we may need more fixes to msg_verify_data, added a TODO

10/11  sockmap::txmsg test push_data:FAIL
11/17  sockmap::txmsg test pull-data:FAIL
12/ 9  sockmap::txmsg test pop-data:FAIL
...
Pass: 37 Fail: 15

Besides, added a custom errno EDATAINTEGRITY for msg_verify_data, we
shall not ignore the error in txmsg_cork case.

[ Upstream commit de1b5ea789dc28066cc8dc634b6825bd6148f38b ]

The value of recv in msg_loop may be negative, like EWOULDBLOCK, so it's
necessary to check if it is positive before accumulating it to bytes_recvd.

[ Upstream commit 6c8d7598dfed759bf1d9d0322b4c2b42eb7252d8 ]

bpf_prog5 and bpf_prog7 are removed from progs/test_sockmap_kern.h in
commit d79a32129b21 ("bpf: Selftests, remove prints from sockmap tests"),
now there are only 9 progs in it, not 11:

	SEC("sk_skb1")
	int bpf_prog1(struct __sk_buff *skb)
	SEC("sk_skb2")
	int bpf_prog2(struct __sk_buff *skb)
	SEC("sk_skb3")
	int bpf_prog3(struct __sk_buff *skb)
	SEC("sockops")
	int bpf_sockmap(struct bpf_sock_ops *skops)
	SEC("sk_msg1")
	int bpf_prog4(struct sk_msg_md *msg)
	SEC("sk_msg2")
	int bpf_prog6(struct sk_msg_md *msg)
	SEC("sk_msg3")
	int bpf_prog8(struct sk_msg_md *msg)
	SEC("sk_msg4")
	int bpf_prog9(struct sk_msg_md *msg)
	SEC("sk_msg5")
	int bpf_prog10(struct sk_msg_md *msg)

This patch updates the array sizes of prog_fd[], prog_attach_type[] and
prog_type[] from 11 to 9 accordingly.
