45 there we don't advertise STREAMS as supported is no need to test
46 the STREAMS related functions. This affects
47 getmsg() getpmsg() putmsg()
48 putpmsg()
50 lockf() and fcntl() are tested in tst-cancel16.
52 pthread_join() is tested in tst-join5.
54 pthread_testcancel()'s only purpose is to allow cancellation. This
55 is tested in several places.
57 sem_wait() and sem_timedwait() are checked in tst-cancel1[2345] tests.
59 mq_send(), mq_timedsend(), mq_receive() and mq_timedreceive() are checked
60 in tst-mqueue8{,x} tests.
62 aio_suspend() is tested in tst-cancel17.
64 clock_nanosleep() is tested in tst-cancel18.

86 /* The WRITE_BUFFER_SIZE value needs to be chosen such that if we set
87 the socket send buffer size to '1', a write of this size on that
88 socket will block.
90 The Linux kernel imposes a minimum send socket buffer size which
91 has changed over the years. As of Linux 3.10 the value is:
93 2 * (2048 + SKB_DATA_ALIGN(sizeof(struct sk_buff)))
95 which is attempting to make sure that with standard MTUs,
96 TCP can always queue up at least 2 full sized packets.
98 Furthermore, there is logic in the socket send paths that
99 will allow one more packet (of any size) to be queued up as
100 long as some socket buffer space remains. Blocking only
101 occurs when we try to queue up a new packet and the send
102 buffer space has already been fully consumed.
104 Therefore we must set this value to the largest possible value of
105 the formula above (and since it depends upon the size of "struct
106 sk_buff", it is dependent upon machine word size etc.) plus some
107 slack space. */
