However, xs_bind() subsequently uses\nthe value of this field without regard to whether the source address\nwas initialized during transport creation or not.\n\nSo far we\u0027ve been lucky: the uninitialized value of this field is\nzeroes. xs_bind(), until recently, used only the sin[6]_addr field in\nthis sockaddr, and all zeroes is a valid value for this: it means\nANYADDR. This is a happy coincidence.\n\nHowever, xs_bind() now wants to use the sa_family field as well, and\nexpects it to be initialized to something other than zero.\n\nTherefore, the source address sockaddr field should be fully\ninitialized at transport create time in _every_ case, not just when\nthe RPC application wants to use a specific bind address.\n\nBruce added a workaround for this missing initialization by adjusting\ncommit 6bc9638a, but the \"right\" way to do this is to ensure that the\nsource address sockaddr is always correctly initialized from the\nget-go.\n\nThis patch doesn\u0027t introduce a behavior change. It\u0027s simply a\nclean-up of Bruce\u0027s fix, to prevent future problems of this kind. It\nmay look like overkill, but\n\n a) it clearly documents the default initial value of this field,\n\n b) it doesn\u0027t assume that the sockaddr_storage memory is first\n initialized to any particular value, and\n\n c) it will fail verbosely if some unknown address family is passed\n in\n\nOriginally introduced by commit d3bc9a1d.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nSigned-off-by: J.

This rule \u0027b\u0027 above will sometimes be effective, but\n not reliably.\n\n When the client closes the connection, it used to result in\n TCP_FIN_WAIT1, TCP_FIN_WAIT2, TCP_CLOSE. However since commit\n f75e674 (SUNRPC: Fix the problem of EADDRNOTAVAIL syslog floods on\n reconnect) we don\u0027t see *any* events on client-close. I think this\n is because xs_restore_old_callbacks is called to disconnect\n xs_tcp_state_change before the socket is closed.\n In any case, rule \u0027a\u0027 no longer applies.\n\nSo all that is left are rule d, which successfully doubles the\ntimeout which is never rest, and rule e which initialises the timeout.\n\nEven if the rules worked as expected, there would be a problem because\na successful connection does not reset the timeout, so a sequence\nof events where the server closes the connection (e.g. during failover\ntesting) will cause longer and longer timeouts with no good reason.\n\nThis patch:\n\n - sets reestablish_timeout to 0 in xs_close thus effecting rule \u0027a\u0027\n - sets it to 0 in xs_tcp_data_ready to ensure that a successful\n connection resets the timeout\n - sets it to at least XS_TCP_INIT_REEST_TO after it is doubled,\n thus effecting rule c\n\nI have not reimplemented rule b and the new version of rule c\nseems sufficient.\n\nI suspect other code in xs_tcp_data_ready needs to be revised as well.\nFor example I don\u0027t think connect_cookie is being incremented as often\nas it should be.\n\nSigned-off-by: NeilBrown \u003cneilb@suse.de\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "f300baba5a1536070d6d77bf0c8c4ca999bb4f0f", "tree": "648d0020d9a9325cfcb07571d9f11a5c797ee900", "parents": [ "908329f2c08b8b5af7b394f709b0ee9c43b93041" ], "author": { "name": "Alexandros Batsakis", "email": "batsakis@netapp.com", "time": "Thu Sep 10 17:33:30 2009 +0300" }, "committer": { "name": "J.
