[Winpcap-bugs] Bug in pcap-new.c compatibility with linux.

[Gianluca Varenni]

This is a known bug in the sources of WinPcap 4.0, 4.0.1 and 4.1 beta (and some previous beta versions as well).

I have already fixed it in source tree, so it will be available in the next release of WinPcap.

Thanks for the report!

Have a nice day

  Hi,

  I am using rpcapd through a linux installation. I applied remote-code.patch and copied the extra files, but there was still a problem. This is it :

  in pcap_open, you recently (my previous codebase was 3.1 ) added the ability to set windows-specific options when opening a device from far away.
  This is the code :

  case PCAP_SRC_IFLOCAL:

  #ifdef WIN32
  //
  // these flags are supported on Windows only
  // 
              fp = pcap_open_live(name, snaplen, (flags & PCAP_OPENFLAG_PROMISCUOUS), read_timeout, errbuf);
  ... (windows specific code follows)

  The first line (the pcap_open_live call) needs to be called regardless of the OS. The code should look like this : 

  case PCAP_SRC_IFLOCAL:
              fp = pcap_open_live(name, snaplen, (flags & PCAP_OPENFLAG_PROMISCUOUS), read_timeout, errbuf);
  #ifdef WIN32
  //
  // these flags are supported on Windows only
  //
  .... (windows specific code follows) 

  I don't know how to create a .patch file that does this change, but it shouldnt take more than 10 seconds for anyone who does.

  Please consider adding this to the main branch, i see this as a clean bug fix... 

  Thanks!
