2022-07-19libstore/globals.cc: Automatically set cores based on cgroup CPU limitAlex Wied
By default, Nix sets the "cores" setting to the number of CPUs which are physically present on the machine. If cgroups are used to limit the CPU and memory consumption of a large Nix build, the OOM killer may be invoked. For example, consider a GitLab CI pipeline which builds a large software package. The GitLab runner spawns a container whose CPU is limited to 4 cores and whose memory is limited to 16 GiB. If the underlying machine has 64 cores, Nix will invoke the build with -j64. In many cases, that level of parallelism will invoke the OOM killer and the build will completely fail. This change sets the default value of "cores" to be ceil(cpu_quota / cpu_period), with a fallback to std::thread::hardware_concurrency() if cgroups v2 is not detected.

2022-07-17local-derivation-goal.cc: detect unprivileged_userns_clone failure modeAdam Joseph
The workaround for "Some distros patch Linux" mentioned in local-derivation-goal.cc will not help in the `--option sandbox-fallback false` case. To provide the user more helpful guidance on how to get the sandbox working, let's check to see if the `/proc` node created by the aforementioned patch is present and configured in a way that will cause us problems. If so, give the user a suggestion for how to troubleshoot the problem.
2022-07-17local-derivation-goal.cc: add comment re: CLONE_NEWUSERAdam Joseph
local-derivation-goal.cc contains a comment stating that "Some distros patch Linux to not allow unprivileged user namespaces." Let's give a pointer to a common version of this patch for those who want more details about this failure mode.
2022-07-16local-derivation-goal.cc: warn if failing and /proc/self/ns/user missingAdam Joseph
This commit causes nix to `warn()` if sandbox setup has failed and `/proc/self/ns/user` does not exist. This is usually a sign that the kernel was compiled without `CONFIG_USER_NS=y`, which is required for sandboxing.
2022-07-16local-derivation-goal.cc: warn if failing due to max_user_namespaces==0Adam Joseph
This commit uses `warn()` to notify the user if sandbox setup fails with errno==EPERM and /proc/sys/user/max_user_namespaces is missing or zero, since that is at least part of the reason why sandbox setup failed. Note that `echo -n 0 > /proc/sys/user/max_user_namespaces` or equivalent at boot time has been the recommended mitigation for several Linux LPE vulnerabilities over the past few years. Many users have applied this mitigation and then forgotten that they have done so.
2022-07-16local-derivation-goal.cc: improve error messages when sandboxing failsAdam Joseph
The failure modes for nix's sandboxing setup are pretty complicated. When nix is unable to set up the sandbox, let's provide more detail about what went wrong. Specifically: * Make sure the error message includes the word "sandbox" so the user knows that the failure was related to sandboxing. * If `--option sandbox-fallback false` was provided, and removing it would have allowed further attempts to make progress, let the user know.
