2020-11-05Fix failure setting OOM score adjustmentFabricio Voznika
When OOM score adjustment needs to be set, all the containers need to be loaded to find all containers that belong to the sandbox. However, each load signals the container to ensure it is still alive. OOM score adjustment is set during creation and deletion of every container, generating a flood of signals to all containers. The fix removes the signal check when it's not needed. There is also a race fetching OOM score adjustment value from the parent when the sandbox exits at the same time (the time it took to signal containers above made this window quite large). The fix is to store the original value in the sandbox state file and use it when the value needs to be restored. Also add more logging and made the existing ones more consistent to help with debugging. PiperOrigin-RevId: 340940799

This was occasionally causing tests to get stuck due to races with the save process, during which the same mutex is acquired. PiperOrigin-RevId: 340789616

2020-11-04Include file size in Merkle hashChong Cai
The file size can now also be verified. Also, since we are zero-padding the last block of the data, we cannot differentiate the cases between zero-padded block from the blocks that are ends with zeroes. With the size included this can be addressed, as those cases would have different file size. PiperOrigin-RevId: 340695510

2020-11-03Make pipe min/max sizes match linux.Nicolas Lacasse
The default pipe size already matched linux, and is unchanged. Furthermore `atomicIOBytes` is made a proper constant (as it is in Linux). We were plumbing usermem.PageSize everywhere, so this is no functional change. PiperOrigin-RevId: 340497006
