About the UNIX socket path length check

Thu Oct 9 16:02:16 UTC 2014

Hi,
In src/core/ngx_inet.c we have this code:
 if (len > sizeof(saun->sun_path)) {
 u->err = "too long path in the unix domain socket";
 return NGX_ERROR;
 }
But a NUL-terminated string requires one byte more. Is it allowed to
omit the NUL byte when the string would not fit otherwise? If not,
this should be changed to:
 if (len >= sizeof(saun->sun_path)) {
 u->err = "too long path in the unix domain socket";
 return NGX_ERROR;
 }

Kind regards,
Peter
