v1.1.0
067aaf85 · ·v1.1.0 -- "A plan depends as much upon execution as it does upon concept." This release only contains very minor changes from v1.1.0-rc.1 and is the first release of the 1.1.y release series of runc. Changed: * libcontainer will now refuse to build without the nsenter package being correctly compiled (specifically this requires CGO to be enabled). This should avoid folks accidentally creating broken runc binaries (and incorrectly importing our internal libraries into their projects). (#3331) Thanks to the following people who made this release possible: * Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp> * Aleksa Sarai <cyphar@cyphar.com> * Kir Kolyshkin <kolyshkin@gmail.com> Signed-off-by: Aleksa Sarai <cyphar@cyphar.com>

v1.1.0-rc.1
55df1fc4 · ·v1.1.0~rc1 -- "He who controls the spice controls the universe." This release is the first release candidate for the next minor release following runc 1.0. It contains all of the bugfixes included in runc 1.0 patch releases (up to and including 1.0.3). A fair few new features have been added, and several features have been deprecated (with plans for removal in runc 1.2). At the moment we only plan to do a single release candidate for runc 1.1, and once 1.1.0 is released we will not continue updating the 1.0.z runc branch. Deprecated: * runc run/start now warns if a new container cgroup is non-empty or frozen; this warning will become an error in runc 1.2. (#3132, #3223) * runc can only be built with Go 1.16 or later from this release onwards. (#3100, #3245) Removed: * `cgroup.GetHugePageSizes` has been removed entirely, and been replaced with `cgroup.HugePageSizes` which is more efficient. (#3234) * `intelrdt.GetIntelRdtPath` has been removed. Users who were using this function to get the intelrdt root should use the new `intelrdt.Root` instead. (#2920, #3239) Added: * Add support for RDMA cgroup added in Linux 4.11. (#2883) * runc exec now produces exit code of 255 when the exec failed. This may help in distinguishing between runc exec failures (such as invalid options, non-running container or non-existent binary etc.) and failures of the command being executed. (#3073) * runc run: new `--keep` option to skip removal exited containers artefacts. This might be useful to check the state (e.g. of cgroup controllers) after the container hasexited. (#2817, #2825) * seccomp: add support for `SCMP_ACT_KILL_PROCESS` and `SCMP_ACT_KILL_THREAD` (the latter is just an alias for `SCMP_ACT_KILL`). (#3204) * seccomp: add support for `SCMP_ACT_NOTIFY` (seccomp actions). This allows users to create sophisticated seccomp filters where syscalls can be efficiently emulated by privileged processes on the host. (#2682) * checkpoint/restore: add an option (`--lsm-mount-context`) to set a different LSM mount context on restore. (#3068) * runc releases are now cross-compiled for several architectures. Static builds for said architectures will be available for all future releases. (#3197) * intelrdt: support ClosID parameter. (#2920) * runc exec --cgroup: an option to specify a (non-top) in-container cgroup to use for the process being executed. (#3040, #3059) * cgroup v1 controllers now support hybrid hierarchy (i.e. when on a cgroup v1 machine a cgroup2 filesystem is mounted to /sys/fs/cgroup/unified, runc run/exec now adds the container to the appropriate cgroup under it). (#2087, #3059) * sysctl: allow slashes in sysctl names, to better match `sysctl(8)`'s behaviour. (#3254, #3257) * mounts: add support for bind-mounts which are inaccessible after switching the user namespace. Note that this does not permit the container any additional access to the host filesystem, it simply allows containers to have bind-mounts configured for paths the user can access but have restrictive access control settings for other users. (#2576) * Add support for recursive mount attributes using `mount_setattr(2)`. These have the same names as the proposed `mount(8)` options -- just prepend `r` to the option name (such as `rro`). (#3272) * Add `runc features` subcommand to allow runc users to detect what features runc has been built with. This includes critical information such as supported mount flags, hook names, and so on. Note that the output of this command is subject to change and will not be considered stable until runc 1.2 at the earliest. The runtime-spec specification for this feature is being developed in opencontainers/runtime-spec#1130. (#3296) Changed: * system: improve performance of `/proc/$pid/stat` parsing. (#2696) * cgroup2: when `/sys/fs/cgroup` is configured as a read-write mount, change the ownership of certain cgroup control files (as per `/sys/kernel/cgroup/delegate`) to allow for proper deferral to the container process. (#3057) * docs: series of improvements to man pages to make them easier to read and use. (#3032) Libcontainer API: * internal api: remove internal error types and handling system, switch to Go wrapped errors. (#3033) * New configs.Cgroup structure fields (#3177): * Systemd (whether to use systemd cgroup manager); and * Rootless (whether to use rootless cgroups). * New cgroups/manager package aiming to simplify cgroup manager instantiation. (#3177) * All cgroup managers' instantiation methods now initialize cgroup paths and can return errors. This allows to use any cgroup manager method (e.g. Exists, Destroy, Set, GetStats) right after instantiation, which was not possible before (as paths were initialized in Apply only). (#3178) Fixed: * nsenter: do not try to close already-closed fds during container setup and bail on close(2) failures. (#3058) * runc checkpoint/restore: fixed for containers with an external bind mount which destination is a symlink. (#3047). * cgroup: improve openat2 handling for cgroup directory handle hardening. (#3030) * `runc delete -f` now succeeds (rather than timing out) on a paused container. (#3134) * runc run/start/exec now refuses a frozen cgroup (paused container in case of exec). Users can disable this using `--ignore-paused`. (#3132, #3223) * config: do not permit null bytes in mount fields. (#3287) Thanks to the following people who made this release possible: * Adrian Reber <areber@redhat.com> * Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp> * Alban Crequy <alban@kinvolk.io> * Aleksa Sarai <cyphar@cyphar.com> * Dave Chen <dave.chen@arm.com> * flouthoc <flouthoc.git@gmail.com> * Fraser Tweedale <ftweedal@redhat.com> * Itamar Holder <iholder@redhat.com> * Kailun Qin <kailun.qin@intel.com> * Kang Chen <kongchen28@gmail.com> * Kir Kolyshkin <kolyshkin@gmail.com> * lifubang <lifubang@acmcoder.com> * Liu Hua <weldonliu@tencent.com> * Maksim An <maksiman@microsoft.com> * Markus Lehtonen <markus.lehtonen@intel.com> * Mauricio Vásquez <mauricio@kinvolk.io> * Mengjiao Liu <mengjiao.liu@daocloud.io> * Mrunal Patel <mrunal@me.com> * Neil Johnson <najohnsn@gmail.com> * Odin Ugedal <odin@uged.al> * Piotr Resztak <piotr.resztak@gmail.com> * Qiang Huang <h.huangqiang@huawei.com> * Rodrigo Campos <rodrigo@kinvolk.io> * Sascha Grunert <sgrunert@redhat.com> * Sebastiaan van Stijn <github@gone.nl> * Shengjing Zhu <zhsj@debian.org> * xiadanni <xiadanni1@huawei.com> Signed-off-by: Aleksa Sarai <cyphar@cyphar.com>

v1.0.3
f46b6ba2 · ·v1.0.3 -- "If you were waiting for the opportune moment, that was it." This is the third stable release in the 1.0 branch, fixing a handful of medium priority issues related to mounts and cgroups, as well as a potential security vulnerability. This release is expected to be the last point release in the 1.0 branch, as we are planning to release runc 1.1 in the near future. Security: * A potential vulnerability was discovered in runc (related to an internal usage of netlink), however upon further investigation we discovered that while this bug was exploitable on the master branch of runc, no released version of runc could be exploited using this bug. The exploit required being able to create a netlink attribute with a length that would overflow a uint16 but this was not possible in any released version of runc. For more information see GHSA-v95c-p5hm-xq8f and CVE-2021-43784. Due to an abundance of caution we decided to do an emergency release with this fix, but to reiterate *we do not believe this vulnerability was possible to exploit*. Thanks to Felix Wilhelm from Google Project Zero for discovering and reporting this vulnerability so quickly. Bugfixes: * Fixed inability to start a container with read-write bind mount of a read-only fuse host mount (#3292) * Fixed inability to start when read-only /dev in set in spec (#3277) * Fixed not removing sub-cgroups upon container delete, when rootless cgroup v2 is used with older systemd (#3297) * Fixed returning error from GetStats when hugetlb is unsupported (which causes excessive logging for kubernetes) (#3295) * [CI only] Fixed criu 3.16 compatibility issue (#3282) * [CI only] Add Go 1.17 to the testing matrix (#3299) Enhancements: * Improved an error message when dbus-user-session is not installed and rootless + cgroup2 + systemd are used (#3212) Thanks to all of the contributors who made this release possible: * Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp> * Aleksa Sarai <cyphar@cyphar.com> * Kailun Qin <kailun.qin@intel.com> * Kang Chen <kongchen28@gmail.com> * Kir Kolyshkin <kolyshkin@gmail.com> * Odin Ugedal <odin@uged.al> * Sebastiaan van Stijn <thaJeztah@users.noreply.github.com> Signed-off-by: Aleksa Sarai <cyphar@cyphar.com>

v1.0.2
52b36a2d · ·v1.0.2 -- "Given the right lever, you can move a planet." This is a second stable release in 1.0 branch, fixing a few medium and high priority issues, including one that affects Kubernetes' usage of runc's libcontainer. Bugfixes: * Fixed a failure to set CPU quota period in some cases on cgroup v1. (#3115) * Fixed the inability to start a container with the "adding seccomp filter rule for syscall ..." error, caused by redundant seccomp rules (i.e. those that has action equal to the default one). Such redundant rules are now skipped. (#3129) * Made release builds reproducible from now on. (#3142) * Fixed a rare debug log race in runc init, which can result in occasional harmful "failed to decode ..." errors from runc run or exec. (#3130) * Fixed the check in cgroup v1 systemd manager if a container needs to be frozen before Set, and add a setting to skip such freeze unconditionally. The previous fix for that issue, done in runc 1.0.1, was not working. (#3167) Thanks to all of the contributors who made this release possible: * Adrian Reber <areber@redhat.com> * Akihiro Suda <akihiro.suda.cz@hco.ntt.co.jp> * Aleksa Sarai <cyphar@cyphar.com> * Kir Kolyshkin <kolyshkin@gmail.com> * Mrunal Patel <mrunal@me.com> * Odin Ugedal <odin@uged.al> Signed-off-by: Aleksa Sarai <cyphar@cyphar.com>

v1.0.1
4144b638 · ·v1.0.1 -- "If in doubt, Meriadoc, always follow your nose." This is the first stable release in the 1.0 branch, fixing a few medium and high priority issues with runc 1.0.0, including a few that affect Kubernetes' usage of libcontainer. Bugfixes: * Fixed occasional runc exec/run failure ("interrupted system call") on an Azure volume. (#3074) * Fixed "unable to find groups ... token too long" error with /etc/group containing lines longer than 64K characters. (#3079) * cgroup/systemd/v1: fix leaving cgroup frozen after Set if a parent cgroup is frozen. This is a regression in 1.0.0, not affecting runc itself but some of libcontainer users (e.g Kubernetes). (#3085) * cgroupv2: bpf: Ignore inaccessible existing programs in case of permission error when handling replacement of existing bpf cgroup programs. This fixes a regression in 1.0.0, where some SELinux policies would block runc from being able to run entirely. (#3087) * cgroup/systemd/v2: don't freeze cgroup on Set. (#3092) * cgroup/systemd/v1: avoid unnecessary freeze on Set.

v1.0.0
84113eef · ·v1.0.0 -- "A wizard is never late, nor is he early, he arrives precisely when he means to." This release fixes a few bugs found (almost all related to cgroupv2 handling), and is the first non-rc release of runc in 5 years (v1.0.0-rc1 was released in 2016). It's been a very long road, and we thank the many contributors and maintainers that helped us get to this point (approximately 422 people in total). As runc follows Semantic Versioning, we will endeavor to not make any breaking changes without bumping the major version number of runc. However, it should be noted that Go API usage of runc's internal implementation (libcontainer) is *not* covered by this policy -- for historical reasons, this code was not moved into an "internal" package (this feature did not exist in Go at the time) and because certain projects currently depend on this, we have not yet moved this code into an internal package. Despite this, we reserve the right to make breaking changes in our Go APIs (though we will note such changes in our changelog, and will try to avoid needless disruption if possible). Breaking changes: * Removed libcontainer/configs.Device* identifiers (deprecated since rc94, use libcontainer/devices) (#2999) * Removed libcontainer/system.RunningInUserNS function (deprecated since rc94, use libcontainer/userns) (#2999) Deprecations: * The usage of relative paths for mountpoints will now produce a warning (such configurations are outside of the spec, and in future runc will produce an error when given such configurations). (#2917, #3004) Bugfixes: * cgroupv2: devices: rework the filter generation to produce consistent results with cgroupv1, and always clobber any existing eBPF program(s) to fix `runc update` and avoid leaking eBPF programs (resulting in errors when managing containers). (#2951) * cgroupv2: correctly convert "number of IOs" statistics in a cgroupv1-compatible way. (#2965, #2967, #2968, #2964) * cgroupv2: support larger than 32-bit IO statistics on 32-bit architectures. * cgroupv2: wait for freeze to finish before returning from the freezing code, optimize the method for checking whether a cgroup is frozen. (#2955) * cgroups/systemd: fixed "retry on dbus disconnect" logic introduced in rc94 * cgroups/systemd: fixed returning "unit already exists" error from a systemd cgroup manager (regression in rc94) (#2997, #2996) Improvements: * cgroupv2: support SkipDevices with systemd driver (#2958, #3019) * cgroup/systemd: return, not ignore, stop unit error from Destroy (#2946) * Fix all golangci-lint failures. (#2781, #2962) * Make "runc --version" output sane even when built with `go get` or otherwise outside of our build scripts. (#2962) * cgroups: set SkipDevices during runc update (so we don't modify cgroups at all during `runc update`). (#2994) * cgroup1: blkio: support BFQ weights. (#3010) * cgroupv2: set per-device io weights if BFQ IO scheduler is available.
