Description

EDIT: Reformatted code for legibility. --bmah

Context

  • Version of iperf3: 3.7

  • Hardware: Sparc

  • Operating system (and distribution, if any):

Solaris 10

  • Other relevant information (for example, non-default compilers, libraries, cross-compiling, etc.):

gcc

  • Possible Solution

Not being used with pull request I submit here some code that seems to fix something under Solaris 10: Add the follwing in iperf_auth.c found this on https://github.com/firnsy/barnyard2/issues/98

#if defined(__sun)
/* Written by Kaveh R. Ghazi <ghazi@caip.rutgers.edu> */
char *
strndup (const char *s, size_t n)
{
  char *result;
  size_t len = strlen (s);

  if (n < len)
    len = n;

  result = (char *) malloc (len + 1);
  if (!result)
    return 0;

  memcpy (result, s, len);
  result[len] = '\0';
  return(result);
}
#endif

Research direction
The issue requires adding a `strndup` implementation in `iperf auth.c` for Solaris 10 compatibility. The provided code snippet can be used directly, but verify that it compiles with GCC on Solaris and does not affect other platforms. Check for any existing conditional compilation for Solaris in the codebase. The reference to another project's issue may offer insights.
