Problem summary

  • APAR NUMBER:  PJ40799
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  'C' LANGUAGE SUPPORT
    SHIPPED IN PUT:  10
    
    ABSTRACT:
    A CTL-230 may occur when logging system messages using syslog.
    
    PACKAGE CONTENTS:
    Source Segments:
    (C) base/rt/csylgd.c
    
    Object Only Binaries:
    None.
    
    Configuration Independent Binaries:
    (C) base/obj/csylgd.o
    (C) base/load/CSYL.so
    
    Support Files:
    base/lst/csylgd.lst
    base/lst/CSYL.map
    
    OTHER BINARIES TO BUILD: NO
    None.
    
    COMMENTS:
    When logging messages, function fprintlog() in program segment
    csylgd.c declares and initializes an integer sized variable,
    bss, to indicate that it is not operating in the BSS and that a
    cebic_restore() must be issued before exiting. When logging
    messages to file, fprintlog() will check the BSS indicator in
    the ECB. If it is not operating in the BSS, a cebic_save() and
    cebic_goto_bss() are issued. Otherwise, the variable, bss, is
    set to indicate that it is operating in the BSS. However, there
    are other paths in this function where the BSS indicator in the
    ECB is not checked. Yet, before exiting, variable bss is still
    checked to determine if a cebic_restore() needs to be issued.
    If, for example, fprintlog() is writing to tape, then a
    cebic_restore() is needlessly issued and a CTL-230 will occur.
    

Problem conclusion

  • SOLUTION:
    In program segment csylgd.c, function fprintlog() has been
    updated to always check the BSS inidicator in the ECB, set
    variable bss, and issue cebic_save and cebic_restore
    accordingly. Before exiting, variable bss will correctly
    indicate whether or not a cebic_restore() must be issued. In
    addition, segment csylgd.c was updated to call ascii2ebcdic()
    and convert a message only if the prior call to recvfrom()
    returned a valid message.
    
    COREQS: NO
