IJ44573: THE POLLSET_QUERY API CAN RETURN INVALID FILE DESCRIPTOR STATUS APPLIES TO AIX 7300-02

APAR status

• Closed as program error.

Error description

• The pollset_query API returns a status of "false" (0),
  indicating that a file descriptor is not a member of
  the specified pollset even though the file descriptor
  actually resides in the pollset, e.g. pollset add
  operation with the same file descriptor fails with
  EINVAL.
  

Local fix

Problem summary

• The pollset_query API returns a status of "false" (0),
  indicating that a file descriptor is not a member of
  the specified pollset even though the file descriptor
  actually resides in the pollset, e.g. pollset add
  operation with the same file descriptor fails with
  EINVAL.
  

Problem conclusion

• Introduce a new system call, pollset_query_type, that allows
  querying a pollset for different types of indentifiers, e.g.
  file descriptor, message queue id, etc. Applications may
  continue to use the existing pollset_query API, but it will
  be limited to only querying file descriptors.
  

Temporary fix
