Re: [Bug 1347322] Re: juju ssh results in a panic: runtime error
btw. This has nothing to do with ssh, it is to do with the length of time the juju cli process is running for. Normally this is a very short period, but juju ssh forks ssh as a child then waits for it to finish. The crash is caused by a bug in the previous runtime (compiled statically into the binary) when the garbage collector had been running for long enough to call madvise(DONT_NEED, ...) with the wrong page size.

[Bug 1347322] Re: juju ssh results in a panic: runtime error
** Description changed: I am using Juju on Power 8 hardware and I get a panic when I use juju to ssh to a system. The reproduction steps are juju init juju bootstrap -e local + juju switch local juju deploy local:trusty/ubuntu juju ssh ubuntu/0 (use the session to the local machine and after some time the panic happens and the screen is unreadable.) ubuntu@ubuntu-local-machine-1:~$ panic: runtime error: invalid memory address or nil pointer dereference [signal 0xb code=0x1 addr=0x8] goroutine 11 [running]: code.google.com_p_go.net_websocket.Send.N40_code. google.com_p_go.net_websocket.Codec /build/buildd/juju-core-1.18.1/src/code.google.com/p/go.net/webso cket/websocket.go:293 launchpad.net_juju_core_rpc_jsoncodec.Send.N48_launchpad.net_juju_core_rpc_jsonc odec.wsJSONConn /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/rpc/jsoncodec/conn.go: 21 launchpad.net_juju_core_rpc_jsoncodec.WriteMessage.pN43_launchpad.net_juju_core_rpc_jsoncodec.Codec /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/rpc/jsoncodec/codec.go:178 launchpad.ne t_juju_core_rpc.send.pN32_launchpad.net_juju_core_rpc.Conn /build/buildd/juju-core-1.18.1/src/launch pad.net/juju-core/rpc/client.go:72 launchpad.net_juju_core_rpc.Go.pN32_launchpad.net_juju_core_rpc.Con n /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/rpc/client.go:174 launchpad.net_juju_co re_rpc.Call.pN32_launchpad.net_juju_core_rpc.Conn /build/buildd/juju-core-1.18.1/src/launchpad.net/ juju-core/rpc/client.go:148 launchpad.net_juju_core_state_api.Call.pN39_launchpad.net_juju_core_state_ api.State /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/state/api/apiclient.go:168 launchpad.net_juju_core_state_api.Ping.pN39_launchpad.net_juju_core_state_api.State /build/buildd/juj u-core-1.18.1/src/launchpad.net/juju-core/state/api/apiclient.go:158 launchpad.net_juju_core_state_api .heartbeatMonitor.pN39_launchpad.net_juju_core_state_api.State /build/buildd/juju-core-1.18.1/sr c/launchpad.net/juju-core/state/api/apiclient.go:149 created by launchpad.net_juju_core_state_api.Open /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/state/api/apiclient.go:143 goroutine 1 [syscall]: goroutine in C code; stack unavailable goroutine 3 [syscall]: goroutine in C code; stac k unavailable goroutine 10 [IO wait]: code.google.com_p_go.net_websocket.ReadByte.N57_code.google.com_p _go.net_websocket.hybiFrameReaderFactory /build/buildd/juju-core-1.18.1/src/code.google.com/p/go.n et/websocket/hybi.go:113 code.google.com_p_go.net_websocket.NewFrameReader.N57_code.google.com_p_go.ne t_websocket.hybiFrameReaderFactory /build/buildd/juju-core-1.18.1/src/code.google.com/p/go.net/webso cket/hybi.go:126 code.google.com_p_go.net_websocket.Receive.N40_code.google.com_p_go.net_websocket.Cod ec /build/buildd/juju-core-1.18.1/src/code.google.com/p/go.net/websocket/websocket.go:314 launchpad.n et_juju_core_rpc_jsoncodec.Receive.N48_launchpad.net_juju_core_rpc_jsoncodec.wsJSONConn /build/bu ildd/juju-core-1.18.1/src/launchpad.net/juju-core/rpc/jsoncodec/conn.go:25 launchpad.net_juju_core_rpc _jsoncodec.ReadHeader.pN43_launchpad.net_juju_core_rpc_jsoncodec.Codec

I have tried to reproduce this problem in utopic on rockne (a P7+ system), and it's not reproducible for me. # grep P /proc/cpuinfo cpu : POWER7+ (raw), altivec supported cpu : POWER7+ (raw), altivec supported machine : CHRP IBM pSeries (emulated by qemu) # uname -a Linux rockne-06 3.13.0-22-generic #44-Ubuntu SMP Wed Apr 2 20:06:28 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux # zgrep 64K_PAGES /proc/config.gz CONFIG_PPC_64K_PAGES=y # sudo apt-get install lxc # lxc-create -n utopic-test -t ubuntu -- --release utopic # sed -i -e'/lxc.aa_profile/d' /var/lib/lxc/utopic-test/config # echo 'lxc.aa_profile = lxc-container-default-with-nesting' /var/lib/lxc/utopic-test/config # echo 'lxc.mount.auto = cgroup' /var/lib/lxc/utopic-test/config # lxc-start --name utopic-test [...] Ubuntu Utopic Unicorn (development branch) utopic-test console utopic-test login: ubuntu Password: ubuntu [...] ubuntu@utopic-test:~$ sudo apt-get install juju juju-local bzr $ mkdir -p charms/trusty $ bzr branch http://bazaar.launchpad.net/~charmers/charms/trusty/ubuntu/trunk/ charms/trusty/ubuntu $ juju init $ juju bootstrap -e local $ juju switch local $ juju deploy --repository=$(pwd)/charms local:trusty/ubuntu $ juju ssh ubuntu/0 [...] ubuntu@ubuntu-local-machine-1:~$ /var/lib/juju/tools/machine-1/jujud --version 1.18.4.1-trusty-ppc64 $ I've stayed logged in for over 10 minutes with no problems, have installed packages inside the container, etc. So there are several variables here: - utopic has juju 1.18.4, not 1.18.1. - the system is a P7+, not a P8 as in the original report. - this is built with the utopic gccgo-4.9 package, not the backported one in trusty. The last of these is unlikely to be the cause. Someone with access to a P8 machine should ideally try to reproduce with this same method there, to check whether this is a P8-specific issue. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to juju-core in Ubuntu. https://bugs.launchpad.net/bugs/1347322 Title: juju ssh results in a panic: runtime error To manage notifications about this bug go to: https://bugs.launchpad.net/juju-core/+bug/1347322/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
