774c3a62d9 1566. [port] Support for the cmsg framework on Solaris and HP/UX. 
This also solved the problem that match-destinations

5d26560e2b 1245. [bug] Treat ENOBUFS, ENOMEM and ENFILE as soft errors for 
accept().

HPUX 11.11 returns ENOBUFS when the TCP connecting is closed before accept.
ENOMEM and ENFILE were also recommend by HP to be treated as soft for accept().

were incorrectly destroyed, causing corruption
                        of socket manager data structures.

7900390a52 Previous change turned invalid peer address returns from accept() 
into hard errors - they should be soft errors
 2001-04-10 21:48:27 +00:00
Andreas Gustafsson
a84cfaa3f2 The bug fix in socket.c 1.189 was less than ideal: if a socket 
got wedged in a state where accept() always returns EBADF, the server would loop calling
internal_accept() repeatedly.  Implemented an alternative fix where a hard
error in accept() causes an event with a nonzero result code to be sent, and
the new socket object to be freed
 2001-04-10 21:38:33 +00:00

2eb3dafdcf Add the socket flag ISC_R_NORETRY, which makes the socket code treat 
a soft error as a hard error on send (that is, not retry it).  It also
modifies the code calling sendmsg() to retry on EINTR.

c05eeed3c9 754. [bug] Certain failure returns from sendto() could 
cause the server to retry the transmission
                        indefinitely. [RT #902]
 2001-02-24 23:51:09 +00:00
Brian Wellington
1f7f8d5c07 Add isc_socket_sendto2() and isc_socket_recv2(). These versions take 
a partially constructed event and flags.  The flags can include
ISC_SOCKFLAG_IMMEDIATE, which means that if the operation completes, the
event is filled in and not sent.

df0bcff664 extend change #727 to check returned address length for zero. 2001-02-07 23:40:28 +00:00
Andreas Gustafsson
9a3ee1570d "hard" errors in accept() were handled really badly. They were logged 
twice, and the socket object for the new socket was never destroyed,
causing the server to hang on exit (if multithreaded) or dump core on exit
(if singlethreaded).  Now the only difference between "hard" and "soft" errors
is that the latter are not logged.
 2001-02-06 23:43:01 +00:00
Andreas Gustafsson
8dab78b566 as a workaround for various OS bugs, do not INSIST() that 
accept() returns a valid peer address; instead just log an ugly error message
and continue if the peer address is left unchanged or insane by accept()
