by Red Hat Bugzilla 08 Jun '16

https://bugzilla.redhat.com/show_bug.cgi?id=1046469 Bug ID: 1046469 Summary: docker privileged mode with cmd /sbin/init - agetty & high cpu Product: Fedora Version: 20 Component: docker-io Assignee: lsm5(a)redhat.com Reporter: fortuik(a)gmail.com QA Contact: extras-qa(a)fedoraproject.org CC: golang(a)lists.fedoraproject.org, lsm5(a)redhat.com, mattdm(a)redhat.com, mgoldman(a)redhat.com, skottler(a)redhat.com, vbatts(a)redhat.com Description of problem: docker containers in privileged mode mess with the host agetty and produce very hicht cpu load Version-Release number of selected component (if applicable): Fedora 20 Docker 0.7.1, 0.7.2 How reproducible: docker run -privileged -d mattdm/fedora:latest /sbin/init Actual results: docker container runs cpu load is very high - agetty stopping the container & the docker daemon do not free the cpu resources one have to kill the agetty process Expected results: docker container runs Additional info: In my real case i run rhel containers with puppet & ssh daemons for a small puppet lab. The reason i met this bug is that running docker container with /sbin/init cmd under RHEL 6.5 require priviliged mode. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 1192081] New: Modify base image Dockerfile to enable systemd to run smoothly

In my opinion, we should add ENV container=docker VOLUME ['/run', '/tmp'] to the base image Dockerfile. Command docker run --it --rm -v /sys/fs/cgroup:/sys/fs/cgroup:ro fedora:rawhide /usr/sbin/init would then be all an user would need to "boot" systemd in a container. I've already made some changes in KS file - remove fstab and machine-id, mask mount units... which make the boot sequence smooth. More changes to boot sequence will probably come later (f.e. switch from graphical.target to multi-user target) I'd also like to suggest new Rawhide build to be pushed to registry. This one works for me quite well: http://koji.fedoraproject.org/koji/taskinfo?taskID=8883309 -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 1250352] New: golang: HTTP request smuggling in net/http library

https://bugzilla.redhat.com/show_bug.cgi?id=1250352 Bug ID: 1250352 Summary: golang: HTTP request smuggling in net/http library Product: Security Response Component: vulnerability Keywords: Security Severity: medium Priority: medium Assignee: security-response-team(a)redhat.com Reporter: amaris(a)redhat.com CC: admiller(a)redhat.com, golang(a)lists.fedoraproject.org, lemenkov(a)gmail.com, renich(a)woralelandia.com, s(a)shk.io, thrcka(a)redhat.com, vbatts(a)redhat.com There have been found potentially exploitable flaws in Golang net/http library affecting versions 1.4.2 and 1.5. Problems: * Double Content-length headers in a request does not generate a 400 error, the second Content-length is ignored. * Invalid headers are parsed as valid headers (like "Content Length:" with a space in the middle) Exploitations: In a situation where the net/http agent HTTP communication with the final http clients is using some reverse proxy (reverse proxy cache, SSL terminators, etc), some requests can be made exploiting the net/http HTTP protocol violations. Attacker could possibly: * bypass security controls on theses previous elements * perform some cache poisoning on these elements * alter the request/response map on these previous elements (for DOS) CVE request: http://seclists.org/oss-sec/2015/q3/237 Upstream patches: https://github.com/golang/go/commit/117ddcb83d7f42d6aa72241240af99ded81118e9 https://github.com/golang/go/commit/300d9a21583e7cf0149a778a0611e76ff7c6680f https://github.com/golang/go/commit/143822585e32449860e624cace9d2e521deee62e -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 1316210] New: Cannot set dm.basesize until docker has been started
by Red Hat Bugzilla 03 Jun '16

https://bugzilla.redhat.com/show_bug.cgi?id=1316210 Bug ID: 1316210 Summary: Cannot set dm.basesize until docker has been started Product: Fedora Version: rawhide Component: docker-io Severity: medium Assignee: ichavero(a)redhat.com Reporter: mason.jones(a)creditkarma.com QA Contact: extras-qa(a)fedoraproject.org CC: adimania(a)gmail.com, admiller(a)redhat.com, golang(a)lists.fedoraproject.org, hushan.jia(a)gmail.com, ichavero(a)redhat.com, jchaloup(a)redhat.com, jperrin(a)centos.org, lsm5(a)redhat.com, mgoldman(a)redhat.com, miminar(a)redhat.com, s(a)shk.io, thrcka(a)redhat.com, vbatts(a)redhat.com, wolfy(a)nobugconsulting.ro Description of problem: When using terraform to bring up a new EC2 instance with Docker, I wanted to modify the dm.basesize option before starting Docker. To do this, my script adds a line to the /etc/sysconfig/docker-storage file: DOCKER_STORAGE_OPTIONS= --storage-opt dm.basesize=50G However, when it then tries to start Docker with systemctl start docker.service I was getting an error: Error starting daemon: error initializing graphdriver: Unknown option dm.basesize I had used this same line before, but realized that it was after Docker had been started at least once on the server. So then I changed things to: systemctl start docker.service Add the line to /etc/sysconfigdocker-storage systemctl restart docker.service This works fine. Maybe Docker needs to be started at least once on the server in order to initialize the storage subsystem somehow? Before that's done, it doesn't recognize the storage option. This is sort of crazy, so is there a proper fix/workaround? Version-Release number of selected component (if applicable): Output of "docker version": Docker version 1.7.1, build 446ad9b/1.7.1 This is on AWS EC2, running CentOS Linux release 7.1.1503 (Core). I first asked this as an issue against Docker (https://github.com/docker/docker/issues/21037) but they said since it's a Red Hat-supported build of Docker it should be asked here. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 1192848] New: docker no longer supports socket-activation
by Red Hat Bugzilla 03 Jun '16

03 Jun '16

https://bugzilla.redhat.com/show_bug.cgi?id=1192848 Bug ID: 1192848 Summary: docker no longer supports socket-activation Product: Fedora Version: 21 Component: docker-io Assignee: lsm5(a)redhat.com Reporter: tim(a)gfxmonk.net QA Contact: extras-qa(a)fedoraproject.org CC: adimania(a)gmail.com, admiller(a)redhat.com, golang(a)lists.fedoraproject.org, hushan.jia(a)gmail.com, jchaloup(a)redhat.com, jperrin(a)centos.org, lsm5(a)redhat.com, mattdm(a)redhat.com, mgoldman(a)redhat.com, miminar(a)redhat.com, s(a)shk.io, thrcka(a)redhat.com, vbatts(a)redhat.com Version-Release number of selected component (if applicable): docker-io-1.4.1-8.fc21.x86_64 How reproducible: Always Steps to Reproduce: $ docker ps Actual results: FATA[0000] Cannot connect to the Docker daemon. Is 'docker -d' running on this host? Expected results: /var/run/docker.sock should automatically start `docker.service` via socket activation. This was the case on fedora 20. Additional info: I looked in the package history, and it looks like it was disabled by: commit aecb9bfe55824e2c9c7be4afce3ac8dd7e3395f5 Author: Lokesh Mandvekar <lsm5(a)fedoraproject.org> Date: Fri Jan 16 17:06:40 2015 +0000 docker group and socket activation not used NVR: docker-io-1.4.1-7 - sysconfig file updates Signed-off-by: Lokesh Mandvekar <lsm5(a)fedoraproject.org> I assume there's a reason for this, but there's no bugzilla or other issue reference, and no description of why the functionality should be removed. The removal of socket activation is pretty annoying, so it would be great if it could be re-enabled. If it can't be enabled, it would be good to document why. -- You are receiving this mail because: You are on the CC list for the bug.
