            Bug ID: 27835
           Summary: inet_nsap_ntoa() strange output
           Product: glibc
           Version: 2.33
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: network
          Assignee: unassigned at sourceware dot org
          Reporter: wharms at bfs dot de
  Target Milestone: ---

Created attachment 13427
  --> https://sourceware.org/bugzilla/attachment.cgi?id=13427&action=edit
simple example using inet_nsap_addr/inet_nsap_ntoa

I played with some undocumented functions and found the output
inet_nsap_ntoa().
I found no documentation about the expected behavior.


inet_nsap_ntoa() converts a given buffer in to a hexstring with dots.
the output looks like that:
 0C.2238.4E0C.2238.4E

you will notice the first and last dot make the output asymmetric.
the code says: 
                if (((i % 2) == 0 && (i + 1) < binlen))
                        *ascii++ = '.';
what does not work as intend because of a *ascii++ the line before. 
changing (i % 2) == 0 to (i % 2) == 1 changes the output into
 0C22.384E.0C22.384E

This is compatible with BSD.

As Andreas wrote, this is the expected output format.
