Add test for mbedtls_net_poll beyond FD_SETSIZE mbedtls_net_poll() and mbedtls_net_recv_timeout() rely on select(), which represents sets of file descriptors through the fd_set type. This type cannot hold file descriptors larger than FD_SETSIZE. Make sure that these functions identify this failure code. Without a proper range check of the file descriptor in the mbedtls_net_xxx function, this test fails when running with UBSan: ``` net_poll beyond FD_SETSIZE ........................................ source/library/net_sockets.c:482:9: runtime error: index 16 out of bounds for type '__fd_mask [16]' SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior source/library/net_sockets.c:482:9 in ``` This is a non-regression test for https://github.com/ARMmbed/mbedtls/issues/4169 . The implementation of this test is specific to Unix-like platforms. Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com> 2021-02-24 19:41:29 +01:00			`net_poll beyond FD_SETSIZE`
