* Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen2016-06-231-3/+0
| | | | | | | | | | | | | | Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause. Everything else stays under GPLv3+. New Linking Exception exempts resulting executables from LGPLv3 section 4. Add CONTRIBUTORS file to keep track of licensing. Remove 'Copyright Red Hat Inc' comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Throughout Cygwin, use u_intN_t or uintN_tCorinna Vinschen2016-03-241-28/+27
| | | | | | | | | | Don't use u_char, u_short, u_int or u_long in Cygwin, unless it refers to the Winsock types. Use u_intN_t in BSD-based sources, unsigned char where strings are concerned, uintN_t otherwise. Also: * net.cc: Fix comment, we're not using u_long anymore.

* cygwin_getaddrinfo: workaround Winsock getaddrinfo issue with broken DNSCorinna Vinschen2016-03-141-1/+10
| | | | | | | | | | | | | | | | | | Add experimental code to workaround the issue described in the thread starting at https://cygwin.com/ml/cygwin/2015-07/msg00350.html There's a hint in https://communities.vmware.com/message/2577858#2577858 that this problem is related to using the AI_ALL flag. This patch checks if GetAddrInfoW returned with WSANO_RECOVERY and if the AI_ALL flag was set, it retries GetAddrInfo without the AI_ALL flag. * net.cc (cygwin_getaddrinfo): Add experimental code to retry GetAddrInfoW without AI_ALL flag if it returned with WSANO_RECOVERY. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* getifaddrs: Return pointer to extended interface info in ifa_data memberCorinna Vinschen2016-03-101-22/+23
| | | | | | | | | | | | | | | | According to https://cygwin.com/ml/cygwin/2016-03/msg00124.html it's a problem to collect friendlyname info using AF_INET6 sockets. Fix problem by exposing additional hardware info for all collected interfaces via the pointer in the ifaddrs::ifa_data member. * include/ifaddrs.h (struct ifaddrs_hwdata): Define as struct of not yet exposed members of struct ifall, defined in net.cc. * net.cc (struct ifall): Replace hardware dta members with struct ifaddrs_hwdata. Accommodate throughout. (get_ifs): Let ifaddrs ifa_data member point to ifall::ifa_hwdata member. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
