Okay, so it's not actually the emulator. The "guest system" (goldfish?) simply kernel panics, see the attachment.
I guess the android source package is still correct though. ** Attachment added: "goldfish-kernel-panic.log" https://bugs.launchpad.net/ubuntu/+source/android/+bug/1420366/+attachment/4317217/+files/goldfish-kernel-panic.log ** Summary changed: - emulator freeze on setsockopt(…IP_ADD_MEMBERSHIP…) + goldfish kernel panic after setsockopt(…IP_ADD_MEMBERSHIP…) ** Description changed: + Update: The "freeze" I explain in this bug is not an emulator freeze + (which I thought at first), but a goldfish kernel panic. + + -------------------------------- + This might be a bug in one of the products the ubuntu emulator is based on, or maybe it's a configuration issue. I don't know so I report this here. I'm trying to use libupnp in the Ubuntu emulator (My app was compiled using a 15.04 framework / i386 "kit" chroot created through ubuntu-sdk on Ubuntu 14.04, the emulator runs the "devel" i386 system image, I think r1, and libupnp is statically linked against my c++ backend module). My system is 14.04 and I use the SDK PPA, so… ubuntu-emulator is version 0.10-0ubuntu1 ubuntu-emulator-runtime is version 20140922-1903-0ubuntu3 There is a problem because InitUpnp() freezes the emulator instead of initializing the library correctly. By single-stepping through that library function and the functions called by that function, I figured out that it probably freezes in a setsockopt() call: (*) > ret = setsockopt(*ssdpSock, IPPROTO_IP, IP_ADD_MEMBERSHIP, > (char *)&ssdpMcastAddr, sizeof(struct ip_mreq)); Line 846: > http://sourceforge.net/p/pupnp/code/ci/master/tree/upnp/src/ssdp/ssdp_server.c#l846 * (That guess is based on the fact that after entering create_ssdp_sock_v4(), there's a sequence of socket(), setsockopt(), bind(), inet_addr(), inet_addr(), setsockopt() and then it freezes when typing "fin" in gdb to return from the last setsockopt call – I don't have enough debug information in the binary to know exactly, and I'm looking at libupnp git master but linking against a precompiled libupnp.a supplied by Ubuntu.) - - That system call apparently changes the socket to receive multicast packets. + That system call apparently changes the socket to receive multicast + packets. Related: http://sourceforge.net/p/pupnp/mailman/message/18352779/ states that the same line of code caused issues for another qemu-based emulator, but that was in 2008 and AIUI qemu is supposed to support IP_ADD_MEMBERSHIP since 2009. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1420366 Title: goldfish kernel panic after setsockopt(…IP_ADD_MEMBERSHIP…) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/android/+bug/1420366/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
