Release notes: https://golang.org/doc/go1.16
The latest Go release, version 1.16, arrives six months after Go 1.15. Most of
its changes are in the implementation of the toolchain, runtime, and libraries.
The linker changes in 1.16 extend the 1.15 improvements to all supported
architecture/OS combinations (the 1.15 performance improvements were primarily
focused on ELF-based OSes and amd64 architectures). For a representative set of
large Go programs, linking is 20-25% faster than 1.15 and requires 5-15% less
memory on average for linux/amd64, with larger improvements for other
architectures and OSes. Most binaries are also smaller as a result of more
aggressive symbol pruning.
According to the release notes, Go 1.16 drops support for x87 mode
compilation (GO386=387). Support for non-SSE2 processors is now available
using soft float mode. Buildroot will automatically set GO386=softfloat on
non-SSE2 processors.

Fixes the following security issues:
- cmd/go: packages using cgo can cause arbitrary code execution at build time
The go command may execute arbitrary code at build time when cgo is in use
on Windows. This may occur when running “go get”, or any other command
that builds code. Only users who build untrusted code (and don’t execute
it) are affected.
In addition to Windows users, this can also affect Unix users who have “.”
listed explicitly in their PATH and are running “go get” or build commands
outside of a module or with module mode disabled.
Thanks to RyotaK (https://twitter.com/ryotkak) for reporting this issue.
This issue is CVE-2021-3115 and Go issue golang.org/issue/43783.
- crypto/elliptic: incorrect operations on the P-224 curve
The P224() Curve implementation can in rare circumstances generate
incorrect outputs, including returning invalid points from ScalarMult.
The crypto/x509 and golang.org/x/crypto/ocsp (but not crypto/tls) packages
support P-224 ECDSA keys, but they are not supported by publicly trusted
certificate authorities. No other standard library or golang.org/x/crypto
package supports or uses the P-224 curve.
The incorrect output was found by the elliptic-curve-differential-fuzzer
project running on OSS-Fuzz and reported by Philippe Antoine (Catena cyber).

Fixes the following security issues:
- math/big: panic during recursive division of very large numbers
A number of math/big.Int methods (Div, Exp, DivMod, Quo, Rem, QuoRem, Mod,
ModInverse, ModSqrt, Jacobi, and GCD) can panic when provided crafted
large inputs. For the panic to happen, the divisor or modulo argument
must be larger than 3168 bits (on 32-bit architectures) or 6336 bits (on
64-bit architectures). Multiple math/big.Rat methods are similarly affected.
crypto/rsa.VerifyPSS, crypto/rsa.VerifyPKCS1v15, and crypto/dsa.Verify may
panic when provided crafted public keys and signatures. crypto/ecdsa and
crypto/elliptic operations may only be affected if custom CurveParams with
unusually large field sizes (several times larger than the largest
supported curve, P-521) are in use. Using crypto/x509.Verify on a crafted
X.509 certificate chain can lead to a panic, even if the certificates
don’t chain to a trusted root. The chain can be delivered via a
crypto/tls connection to a client, or to a server that accepts and
verifies client certificates. net/http clients can be made to crash by an
HTTPS server, while net/http servers that accept client certificates will
recover the panic and are unaffected.
Moreover, an application might crash invoking
crypto/x509.(*CertificateRequest).CheckSignature on an X.509 certificate
request or during a golang.org/x/crypto/otr conversation. Parsing a
golang.org/x/crypto/openpgp Entity or verifying a signature may crash.
Finally, a golang.org/x/crypto/ssh client can panic due to a malformed
host key, while a server could panic if either PublicKeyCallback accepts a
malformed public key, or if IsUserAuthority accepts a certificate with a
malformed public key.
Thanks to the Go Ethereum team and the OSS-Fuzz project for reporting
this. Thanks to Rémy Oudompheng and Robert Griesemer for their help
developing and validating the fix.
This issue is CVE-2020-28362 and Go issue golang.org/issue/42552.
- cmd/go: arbitrary code execution at build time through cgo
The go command may execute arbitrary code at build time when cgo is in
use. This may occur when running go get on a malicious package, or any
other command that builds untrusted code.
This can be caused by malicious gcc flags specified via a #cgo directive,
or by a malicious symbol name in a linked object file.
Thanks to Imre Rad and to Chris Brown and Tempus Ex respectively for

The Go compiler needs to know the "import path" to the root of package
source repositories. Previously, this was done by creating a fake
_gopath in the build directory and symlinking the package source into
that path.
Go has deprecated the GOPATH mechanism in favor of a new approach -
Modules - which specifies the root import path (and dependencies) in a
"go.mod" file. This commit moves Buildroot to use the new go.mod
approach, which requires:
- Passing GO111MODULE=on when building host or target Go packages.
- Passing GOPROXY=off and -mod=vendor to prevent the Go module system
from downloading by itself sources from the Internet. We currently
only support Go packages that have all their dependencies in their
source tree in "vendor" directories.
- Specifying a <pkg>_GOMOD variable, which is used both to create a
minimal go.mod file in the package source tree if it exists, and to
invoke the right build targets. Indeed, all elements in
<pkg>_BUILD_TARGETS are now relative to <pkg>_GOMOD.

package/go/go.mk provides a HOST_GO_TARGET_ENV which provides a useful

For host packages, we simply have package/pkg-golang.mk defining
GO_HOST_ENV to specify CFLAGS/LDFLAGS, but that's it: we don't pass an
explicit path to the compiler, we don't pass GO111MODULE, GOCACHE,
GOROOT, etc.
This commit introduces a HOST_GO_HOST_ENV variable that provides the
appropriate set of environment variables to use when building host
golang packages.

The go toolchain can cross-compile by default. So most of the time,
building a toolchain that supports a target, allows us to also build go
binaries for the host. This is how support for host go packages was
added: we use the same toolchain that was initially built only for
target.
But we might want to build a go binary for the host, when compiling a
target for which go isn't supported. Then, building host-go will fail:
by default, we build go for a specific target, and give the toolchain
bootstrap scripts the cross compiler we'll use.
This change modifies this behaviour: we only assume the go toolchain is
cross-capable if we know the current target is supported. Otherwise this
is a simple host go tool. We don't need to set any of the options needed
for cross-compilation in that case.
Thus, only set all the target-specific go options under a condition that
the target arch is supported. The only option we still set is
HOST_GO_CGO_ENABLED, and we always set it to enabled.
It was also considered to create a separate package to build the
go-for-host compiler which would be used for host-go-packages, but that
would lead to a lot of duplication and is completely unnecessary.

The hidden Config.in option BR2_PACKAGE_HOST_GO_ARCH_SUPPORTS name is
not very clear as to whether it says whether Go is available for the
target architecture or the host architecture.
Until now, this was fine since there was support for host Go
packages. But as we are about to introduce support for building host
Go packages, we need to clarify the meaning of
BR2_PACKAGE_HOST_GO_ARCH_SUPPORTS. Since it says whether the target
architecture has support for Go or not, we rename it to
BR2_PACKAGE_HOST_GO_TARGET_ARCH_SUPPORTS.
And since BR2_PACKAGE_HOST_GO_CGO_LINKING_SUPPORTS is tightly related,
we rename it to BR2_PACKAGE_HOST_GO_TARGET_CGO_LINKING_SUPPORTS.

In Go 1.12, module support remains the same as in Go 1.11. GOPATH is scheduled
for deprecation in 1.13, however. The Buildroot Go package infrastructure should
therefore aim to migrate to a new, currently undefined, Go module friendly

Go "modules" refers to the dependency fetching, verification (hashing), and
version control system built into Go as of 1.11.
It is not desirable to have Go modules enabled in Buildroot in the normal case,
as Buildroot manages downloading the sources, and third party dependency
managers are typically not used.
In the absence of the GO111MODULE environment variable, the Go compiler will
correctly compile using the "vendor" version of dependencies downloaded by
Buildroot during the compilation process for Go-based packages.
However, if the user sets the GO111MODULE=on environment variable, the Go
compiler will download the Go dependencies for Buildroot packages, using the
modules system. This is potentially unintended behavior from user environment
variables.
This commit sets the GO111MODULE=off variable in the Go target and host
compilation environments, disabling Go modules support for Buildroot mainline
packages.
