NOTICE:

Application of this PTF may disable or render ineffective programs that
use system memory addresses not generated by the IBM translator,
including programs that circumvent control technology designed to limit
interactive capacity to purchased levels.  This PTF may be a prerequisite
for future PTFs.  By applying this PTF you authorize and agree to the
foregoing.

This PTF is subject to the terms of the 'IBM License Agreement for Machine
Code', the terms of which were provided in a printed document that was
delivered with the machine.

SUBJECT TO ANY WARRANTIES WHICH CAN NOT BE EXCLUDED OR EXCEPT AS EXPLICITLY
AGREED TO IN THE APPLICABLE LICENSE AGREEMENT OR AN APPLICABLE SUPPORT
AGREEMENT, IBM MAKES NO WARRANTIES OR CONDITIONS EITHER EXPRESS OR IMPLIED,
INCLUDING BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OR CONDITIONS OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON INFRINGEMENT,
REGARDING THE PTF.





APAR Error Description / Circumvention

-----------------------------------------------
An application used the sendmsg()--Send a Message Over a Socket
function to pass a descriptor for a character special file
(*CHRSF) to another job.  The second job was able to use the
recvmsg()--Receive a Message Over a Socket function to receive
the *CHRSF descriptor, but some functions using that descriptor
failed.

CORRECTION FOR APAR MA46564 :
-----------------------------
Internal information was not set correctly during the recvmsg()
processing for the *CHRSF descriptor incorrectly indicating some
functions could not be performed on the descriptor.  The PTF
correctly sets the information to correctly indicate which
functions are supported.

This may also affect applications using the
givedescriptor()--Pass Descriptor Access to Another Job and
takedescriptor()--Receive Socket Access from Another Job APIs to
pass a *CHRSF descriptor to another Job.

CIRCUMVENTION FOR APAR MA46564 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


If the PTF is applied as an immediate PTF, active jobs that use *CHRSF
descriptors should be ended and restarted to activate the fix in those
jobs. If the PTF is applied as a delayed PTF, no further action is
necessary.

********************************************************************
THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED
PTF HAS ALREADY BEEN APPLIED AND ITS SPECIAL INSTRUCTION FOLLOWED,
IT IS NOT NECESSARY TO FOLLOW THAT SPECIAL INSTRUCTION AGAIN.
********************************************************************

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF MF58299 :

be ended and restarted to activate the fix in those jobs. If
the PTF is applied as a delayed PTF, no further action is
necessary.
