2019-08-05selftests/tls: add a litmus test for the socket reuse through shutdownJakub Kicinski
Make sure that shutdown never works, and at the same time document how I tested to came to the conclusion that currently reuse is not possible. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Add a test which sends 15 bytes of data, and then tries to read 10 byes twice.

2019-01-17selftests/tls: Fix recv partial/large_buff test casesVakul Garg
TLS test cases recv_partial & recv_peek_large_buf_mult_recs expect to receive a certain amount of data and then compare it against known strings using memcmp. To prevent recvmsg() from returning lesser than expected number of bytes (compared in memcmp), MSG_WAITALL needs to be passed in recvmsg().

2018-10-01selftests/tls: Fix recv(MSG_PEEK) & splice() test casesVakul Garg
TLS test cases splice_from_pipe, send_and_splice & recv_peek_multiple_records expect to receive a given nummber of bytes and then compare them against the number of bytes which were sent. Therefore, system call recv() must not return before receiving the requested number of bytes, otherwise the subsequent memcmp() fails. This patch passes MSG_WAITALL flag to recv() so that it does not return prematurely before requested number of bytes are copied to receive buffer.

2018-09-17selftests/tls: Add MSG_WAITALL in recv() syscallVakul Garg
A number of tls selftests rely upon recv() to return an exact number of data bytes. When tls record crypto is done using an async accelerator, it is possible that recv() returns lesser than expected number bytes. This leads to failure of many test cases. To fix it, MSG_WAITALL has been used in flags passed to recv() syscall. Signed-off-by: Vakul Garg <vakul.garg@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-17tls: fix currently broken MSG_PEEK behaviorDaniel Borkmann
In kTLS MSG_PEEK behavior is currently failing, strace example: [pid 2430] socket(AF_INET, SOCK_STREAM, IPPROTO_IP) = 3 [pid 2430] socket(AF_INET, SOCK_STREAM, IPPROTO_IP) = 4 [pid 2430] bind(4, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("0.0.0.0")}, 16) = 0 [pid 2430] listen(4, 10) = 0 [pid 2430] getsockname(4, {sa_family=AF_INET, sin_port=htons(38855), sin_addr=inet_addr("0.0.0.0")}, [16]) = 0 [pid 2430] connect(3, {sa_family=AF_INET, sin_port=htons(38855), sin_addr=inet_addr("0.0.0.0")}, 16) = 0 [pid 2430] setsockopt(3, SOL_TCP, 0x1f /* TCP_??? */, [7564404], 4) = 0 [pid 2430] setsockopt(3, 0x11a /* SOL_?? */, 1, "\3\0033\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 40) = 0 [pid 2430] accept(4, {sa_family=AF_INET, sin_port=htons(49636), sin_addr=inet_addr("127.0.0.1")}, [16]) = 5 [pid 2430] setsockopt(5, SOL_TCP, 0x1f /* TCP_??? */, [7564404], 4) = 0 [pid 2430] setsockopt(5, 0x11a /* SOL_?? */, 2, "\3\0033\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 40) = 0 [pid 2430] close(4) = 0 [pid 2430] sendto(3, "test_read_peek", 14, 0, NULL, 0) = 14 [pid 2430] sendto(3, "_mult_recs\0", 11, 0, NULL, 0) = 11 [pid 2430] recvfrom(5, "test_read_peektest_read_peektest"..., 64, MSG_PEEK, NULL, NULL) = 64 As can be seen from strace, there are two TLS records sent, i) 'test_read_peek' and ii) '_mult_recs\0' where we end up peeking 'test_read_peektest_read_peektest'. This is clearly wrong, and what happens is that given peek cannot call into tls_sw_advance_skb() to unpause strparser and proceed with the next skb, we end up looping over the current one, copying the 'test_read_peek' over and over into the user provided buffer. Here, we can only peek into the currently held skb (current, full TLS record) as otherwise we would end up having to hold all the original skb(s) (depending on the peek depth) in a separate queue when unpausing strparser to process next records, minimally intrusive is to return only up to the current record's size (which likely was what c46234ebb4d1 ("tls: RX path for ktls") originally intended as well). Thus, after patch we properly peek the first record: [pid 2046] wait4(2075, <unfinished ...> [pid 2075] socket(AF_INET, SOCK_STREAM, IPPROTO_IP) = 3 [pid 2075] socket(AF_INET, SOCK_STREAM, IPPROTO_IP) = 4 [pid 2075] bind(4, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("0.0.0.0")}, 16) = 0 [pid 2075] listen(4, 10) = 0 [pid 2075] getsockname(4, {sa_family=AF_INET, sin_port=htons(55115), sin_addr=inet_addr("0.0.0.0")}, [16]) = 0 [pid 2075] connect(3, {sa_family=AF_INET, sin_port=htons(55115), sin_addr=inet_addr("0.0.0.0")}, 16) = 0 [pid 2075] setsockopt(3, SOL_TCP, 0x1f /* TCP_??? */, [7564404], 4) = 0 [pid 2075] setsockopt(3, 0x11a /* SOL_?? */, 1, "\3\0033\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 40) = 0 [pid 2075] accept(4, {sa_family=AF_INET, sin_port=htons(45732), sin_addr=inet_addr("127.0.0.1")}, [16]) = 5 [pid 2075] setsockopt(5, SOL_TCP, 0x1f /* TCP_??? */, [7564404], 4) = 0 [pid 2075] setsockopt(5, 0x11a /* SOL_?? */, 2, "\3\0033\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 40) = 0 [pid 2075] close(4) = 0 [pid 2075] sendto(3, "test_read_peek", 14, 0, NULL, 0) = 14 [pid 2075] sendto(3, "_mult_recs\0", 11, 0, NULL, 0) = 11 [pid 2075] recvfrom(5, "test_read_peek", 64, MSG_PEEK, NULL, NULL) = 14 Fixes: c46234ebb4d1 ("tls: RX path for ktls") Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: David S.
