This makes packages use lapack and blas, which can wrap different
BLAS/LAPACK implementations.
treewide: cleanup from blas/lapack changes
A few issues in the original treewide:
- can’t assume blas64 is a bool
- unused commented code
This is based on previous work for switching between BLAS and LAPACK
implementation in Debian[1] and Gentoo[2]. The goal is to have one way
to depend on the BLAS/LAPACK libraries that all packages must use. The
attrs “blas” and “lapack” are used to represent a wrapped BLAS/LAPACK
provider. Derivations that don’t care how BLAS and LAPACK are
implemented can just use blas and lapack directly. If you do care what
you get (perhaps for some CPP), you should verify that blas and lapack
match what you expect with an assertion.
The “blas” package collides with the old “blas” reference
implementation. This has been renamed to “blas-reference”. In
addition, “lapack-reference” is also included, corresponding to
“liblapack” from Netlib.org.
Currently, there are 3 providers of the BLAS and LAPACK interfaces:
- lapack-reference: the BLAS/LAPACK implementation maintained by netlib.org
- OpenBLAS: an optimized version of BLAS and LAPACK
- MKL: Intel’s unfree but highly optimized BLAS/LAPACK implementation
By default, the above implementations all use the “LP64” BLAS and
LAPACK ABI. This corresponds to “openblasCompat” and is the safest way
to use BLAS/LAPACK. You may received some benefits from “ILP64” or
8-byte integer BLAS at the expense of breaking compatibility with some
packages.
This can be switched at build time with an override like:
import <nixpkgs> {
config.allowUnfree = true;
overlays = [(self: super: {
lapack = super.lapack.override {
lapackProvider = super.lapack-reference;
};
blas = super.blas.override {
blasProvider = super.lapack-reference;
};
})];
}
or, switched at runtime via LD_LIBRARY_PATH like:
$ LD_LIBRARY_PATH=$(nix-build -E '(with import <nixpkgs> {}).lapack.override { lapackProvider = pkgs.mkl; is64bit = true; })')/lib:$(nix-build -E '(with import <nixpkgs> {}).blas.override { blasProvider = pkgs.mkl; is64bit = true; })')/lib ./your-blas-linked-binary
By default, we use OpenBLAS LP64 also known in Nixpkgs as
openblasCompat.

* ghcHEAD: bump to 8.11.20200403
* ghcHead: reduce diff vs. 8.10.1
dontAddExtraLibs was removed by accident (IMO) in ea19a8ed1e
* ghcHEAD: add ability to use system libffi
- enable nixpkgs' libffi
- minimise diffs against 8.10.1
- remove patching
* remove configure warning about --with-curses-includes

This is an updated version of the former upstream,
https://github.com/AndroidHardeningArchive/linux-hardened, and provides
a minimal set of additional hardening patches on top of upstream.
The patch already incorporates many of our hardened profile defaults,
and releases are timely (Linux 5.5.15 and 5.6.2 were released on
2020-04-02; linux-hardened patches for them came out on 2020-04-03 and
2020-04-04 respectively).
This commit migrates the Nomad package from the 0.10.x line of releases
to 0.11.X.
This allows us to also bump the version of Go that is used to 1.14.x.
NOTE: 1.14.x will be needed for the rest of the 0.11.x releases as Nomad
only bumps patch versions of Go within a release series.
CHANGELOG:
FEATURES:
Container Storage Interface [beta]: Nomad has expanded support
of stateful workloads through support for CSI plugins.
Exec UI: an in-browser terminal for connecting to running allocations.
Audit Logging (Enterprise): Audit logging support for Nomad
Enterprise.
Scaling APIs: new scaling policy API and job scaling APIs to support external autoscalers
Task Dependencies: introduces lifecycle stanza with prestart and sidecar hooks for tasks within a task group
BACKWARDS INCOMPATIBILITIES:
driver/rkt: The Rkt driver is no longer packaged with Nomad and is instead
distributed separately as a driver plugin. Further, the Rkt driver codebase
is now in a separate
repository.
