runc v1.4.2 -- "Я — Земля! Я своих провожаю питомцев"

This is the second patch release of the 1.4.z release series of runc.

Fixed

• A regression in runc v1.3.0 which can result in a stuck runc exec or runc run when the container process runs for a short time. (#5208, #5210, #5216)

• Mount sources that need to be open on the host are now closed earlier during container start, reducing the total amount of used file descriptors and helping to avoid hitting the open files limit when handling many such mounts. (#5177, #5201)

Static Linking Notices

The runc binary distributed with this release are statically linked with the following GNU LGPL-2.1 licensed libraries, with runc acting as a "work that uses the Library":

• libseccomp

The versions of these libraries were not modified from their upstream versions, but in order to comply with the LGPL-2.1 (§6(a)), we have attached the complete source code for those libraries which (when combined with the attached runc source code) may be used to exercise your rights under the LGPL-2.1.

However we strongly suggest that you make use of your distribution's packages or download them from the authoritative upstream sources, especially since these libraries are related to the security of your containers.

Hi @dependabot[bot]. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Details

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
