Report 1648 Actions Problem Report Number 1648 Submitter's Classification Test Suite problem State Resolved Resolution Permanent Interpretation (PIN) Problem Resolution ID PIN.X.0205 Raised 2002-10-01 08:00 Updated 2003-03-13 08:00 Published 2002-10-08 08:00 Product Standard Sockets V2 (UNIX 98) Certification Program The Open Brand certification program Test Suite VSU version 5.1.2 Test Identification CAPI.os/sockets/connect 3,4,5,6,7,8 Specification Networking Services Issue 5 Location in Spec See Problem Text Problem Summary PIN4U.00071 This IR claims that historical listen() behavior should be allowed in UNIX98 Problem Text Tests 3, 4, 5, 6, 7, and 8 make a listen() call with the second parameter 'backlog' value explicitly set to be 2: tet_infoline("PREP: Child: listen on socket with backlog of 2"); s2 = listen(sc, 2); These tests were designed to have queue depth of incoming connection queue to be 2. However, according to IRIX listen(2) man page: The system actually enforces the limit of pending connections as ((3 * backlog) / 2) + 1 For example, a backlog of 32 will allow 49 outstanding connections. So, a value of 2 would yield the queue depth of 4. The failure of the above 6 tests were caused by this. By changing the backlog value to be 1, which would yield a queue depth of 2, all six tests would pass. Two other tests, test 14 and test 17 also make calls to listen() with backlog value of 2. Since these two tests were to test something else, the value does not matter. Changing the value to 1 did not affect the outcome of these tests. So, we request Open Group to make this parameter a configurable variable so that we can assign a value that meets the purpose the above tests were designed to perform, with either a Temporary Interpretation or TSD to cover this situation until that is done.

as PIN4U.00046. Although the wording of the specification changed slightly between XNS4 and XNS5, the same grey area still exists in XNS5, and so a new PIN should be issued that can be referenced in UNIX98 registrations. It is recommended that a permanent interpretation is granted.
