Abstract

LIC-COMM-OTHER SOCKETS RECEIVE DATA FAILS AFTER REMOTE CLOSE
END OF ABSTRACT

Error Description

Remote side of a connection closes and the local socket issues  
a send that fails with errno value of EPIPE. Receives fail      
with errno value of ECONNRESET, even if there is valid data    
queued.                                                        

Problem Summary

After the remote side of a connection closes and the local      
socket issues a send that fails with errno value of EPIPE,      
receives fail with errno value of ECONNRESET even if there is  
valid data queued.                                              

Problem Conclusion

The receive code path was updated so that any valid data queued
on the socket is returned after the remote side is reset. After
all data is received from the socket, the next receive fails    
with errno value of ECONNRESET. Additional receives after that  
point get a return code of 0 indicating end of file.            

Temporary Fix

Comments

The receive code path was updated so that any valid data queued
on the socket is returned after the remote side is reset. After
all data is received from the socket, the next receive fails    
with errno value of ECONNRESET. Additional receives after that  
point get a return code of 0 indicating end of file.
