crypto/rsa assumes RSA OAEP uses the same hash to be used for both the label
and the mask generation function. However, implementations in other languages,
such as Java and Python, allow these parameters to be specified independently.
This change allows the MGF hash to be specified independently for decrypt
operations in order to allow decrypting ciphertexts generated in other
environments.

Extend the context package to allow users to specify why a context was
canceled in the form of an error, the "cause". Users write the cause
by calling WithCancelCause to construct a derived context, then
calling cancel(cause) to cancel the context with the provided cause.
Users retrieve the cause by calling context.Cause(ctx), which returns
the cause of the first cancelation for ctx or any of its parents.
The cause is implemented as a field of cancelCtx, since only cancelCtx
can be canceled. Calling cancel copies the cause to all derived (child)
cancelCtxs. Calling Cause(ctx) finds the nearest parent cancelCtx by
looking up the context value keyed by cancelCtxKey.
API changes:
+pkg context, func Cause(Context) error
+pkg context, func WithCancelCause(Context) (Context, CancelCauseFunc)
+pkg context, type CancelCauseFunc func(error)

Implement CLONE_INTO_CGROUP feature, allowing to put a child in a
specified cgroup in a clean and simple way. Note that the feature only
works for cgroup v2, and requires Linux kernel 5.7 or newer.
Using the feature requires a new syscall, clone3. Currently this is the
only reason to use clone3, but the code is structured in a way so that
other cases may be easily added in the future.
Add a test case.
While at it, try to simplify the syscall calling code in
forkAndExecInChild1, which became complicated over time because:
1. It was using either rawVforkSyscall or RawSyscall6 depending on
whether CLONE_NEWUSER was set.
2. On Linux/s390, the first two arguments to clone(2) system call are
swapped (which deserved a mention in Linux ABI hall of shame). It
was worked around in rawVforkSyscall on s390, but had to be
implemented via a switch/case when using RawSyscall6, making the code
less clear.
Let's
- modify rawVforkSyscall to have two arguments (which is also required
for clone3);
- remove the arguments workaround from s390 asm, instead implementing
arguments swap in the caller (which still looks ugly but at least
it's done once and is clearly documented now);
- use rawVforkSyscall for all cases (since it is essentially similar to
RawSyscall6, except for having less parameters, not returning r2, and
saving/restoring the return address before/after syscall on 386 and
amd64).

done in the runtime package):
- remove the CLONE_* constants from zerrors_linux_*.go;
- patch mkerrors.sh to not generate CLONE_ constants

Add a new Rewrite hook to ReverseProxy, superseding the Director hook.
Director does not distinguish between the inbound and outbound request,
which makes it possible for headers added by Director to be inadvertently
removed before forwarding if they are listed in the inbound request's
Connection header. Rewrite accepts a value containing the inbound
and outbound requests, with hop-by-hop headers already removed from
the outbound request, avoiding this problem.
ReverseProxy's appends the client IP to the inbound X-Forwarded-For
header by default. Users must manually delete untrusted X-Forwarded-For
values. When used with a Rewrite hook, ReverseProxy now strips
X-Forwarded-* headers by default.
NewSingleHostReverseProxy creates a proxy that does not rewrite the
Host header of inbound requests. Changing this behavior is
cumbersome, as it requires wrapping the Director function created
by NewSingleHostReverseProxy. The Rewrite hook's ProxyRequest
parameter provides a SetURL method that provides equivalent
functionality to NewSingleHostReverseProxy, rewrites the Host
header by default, and can be more easily extended with additional
customizations.

Sometimes when implementing a Formatter it's helpful to use the fmt
package without invoking the formatter. This new function, FormatString,
makes that easier in some cases by recreating the original formatting
directive (such as "%3.2f") that caused Formatter.Format to be
called.
The original Formatter interface is probably not what we would
design today, but we're stuck with it. FormatString, although it
takes a State as an argument, compensates by making Formatter a
little more flexible.
The State does not include the verb so (unlike in the issue), we
must provide it explicitly in the call to FormatString. Doing it there
minimizes allocations by returning the complete format string.

Historically, Objects in go/types were canonical, meaning each entity
was represented by exactly one variable and could thus be identified by
its address. With object instantiation this is no longer the case: Var
and Func objects must be copied to hold substituted type information,
and there may be more than one Var or Func variable representing the
same source-level entity.
This CL adds Origin methods to *Var and *Func, so users can efficiently
navigate to the corresponding canonical object on the generic type.

These are straightforward variants of the existing Sprintf etc.,
but append the resulting bytes to a provided buffer rather than
returning a string.
Internally, there is potentially some allocation because the package
uses a pool of buffers to build its output. We make no attempt to
override that, so the result is first printed into the pool and
then copied to the output. Since it is a managed pool, asymptotically
there should be no extra allocation.

These implementations will inline to the lower-level primitives,
but they hide the underlying values so that all accesses are
forced to use the atomic APIs. They also allow the use of shorter

CL 381374 was reverted because x/sys/execabs broke.
This CL reapplies CL 381374, but adding a lookPathErr error
field back, for execabs to manipulate with reflect.
That field will just be a bit of scar tissue in this package forever,
to keep old code working with new toolchains.
CL 403256 fixes x/sys/execabs's test to be ready for the change.
Older versions of x/sys/execabs will keep working
(that is, will keep rejecting what they should reject),
but they will return a slightly different error from LookPath
without that CL, and the test fails because of the different
error text.

Adds a new, cryptobyte based, CRL parser, which returns a
x509.RevocaitonList, rather than a pkix.CertificateList. This allows us
to return much more detailed information, as well as leaving open the
option of adding further information since RevocationList is not a
direct ASN.1 representation like pkix.CertificateList. Additionally
a new method is added to RevocationList, CheckSignatureFrom, which is
analogous to the method with the same name on Certificate, which
properly checks that the signature is from an issuing certiifcate.
This change also deprecates a number of older CRL related functions and
types, which have been replaced with the new functionality introduced
in this change:
* crypto/x509.ParseCRL
* crypto/x509.ParseDERCRL
* crypto/x509.CheckCRLSignature

Add a fuzz test to verify that calling the String method on any
BuildInfo returned by Parse produces a string that parses to the same
BuildInfo. (Note that this doesn't ensure that String always produces
a parseable input: we assume that a user constructing a BuildInfo

This method is unused and was not discussed in the API
proposals. Note that all error output goes through the
local sprintf which handles arguments specially.
Fixes#50760.

This patch reworks the handling of the DWARF DW_AT_bit_offset and
DW_AT_data_bit_offset attributes to resolve problems arising from
a previous related change (CL 328709).
In CL 328709 the DWARF type reader was updated to look for and use
the DW_AT_data_bit_offset attribute for structure fields, handling
the value of the attribute in the same way as for DW_AT_bit_offset.
This caused problems for clients, since the two attributes have very
different semantics.
This CL effectively reverts CL 328709 and moves to a scheme in which
we detect and report the two attributes separately/independently.
This patch also corrects a problem in the DWARF type reader in the
code that detects and fixes up the type of struct fields corresponding
to zero-length arrays; the code in question was testing the
DW_AT_bit_offset attribute value but assuming DW_AT_data_bit_offset
semantics, meaning that it would fail to fix up cases such as
typedef struct another_struct {
unsigned short quix;
int xyz[0];
unsigned x:1;
long long array[40];
} t;
The code in question has been changed to avoid using BitOffset and
instead consider only ByteOffset and BitSize.
Fixes#50685.
Updates #46784.

CL 331490 and friends added new API to package syscall.
This was a mistake that we need to fix before Go 1.18 is released.

When the go command builds a binary, it will now stamp the current
revision from the local Git or Mercurial repository, and it will also
stamp whether there are uncommitted edited or untracked files. Only
Git and Mercurial are supported for now.
If no repository is found containing the current working directory
(where the go command was started), or if either the main package
directory or the containing module's root directory is outside the
repository, no VCS information will be stamped. If the VCS tool is
missing or returns an error, that error is reported on the main
package (hinting that -buildvcs may be disabled).
This change introduces the -buildvcs flag, which is enabled by
default. When disabled, VCS information won't be stamped when it would
be otherwise.
Stamped information may be read using 'go version -m file' or
debug.ReadBuildInfo.

These functions provide access to module information stamped into Go
binaries. In the future, they'll provide access to other information
(like VCS info).
These functions are added in a new package instead of runtime/debug
since they use binary parsing packages like debug/elf, which would
make runtime/debug an unacceptably heavy dependency. The types in
runtime/debug are still used; debug/buildinfo uses them via type
aliases.
This information is already available for the running binary through
debug.ReadBuildInfo and for other binaries with 'go version -m', but
until now, there hasn't been a way to get it for other binaries
without installing cmd/go.
This change copies most of the code in cmd/go/internal/version. A
later CL will migrate 'go version -m' to use this package.

Previously, modload.PackageBuildInfo returned a string containing
information about modules used to build an executable. This string is
embedded in the binary and can be read with debug.ReadBuildInfo or
'go version -m'.
With this change, debug.BuildInfo now has a MarshalText method that
returns a string in the same format as modload.PackageBuildInfo.
Package.load now calls Package.setBuildInfo, which constructs a
debug.BuildInfo, formats it with MarshalText, then sets
Package.Internal.BuildInfo. This is equivalent to what
modload.PackageBuildInfo did.
modload.PackageBuildInfo is deleted, since it's no longer used.

Otherwise the type checker defaults to amd64, which can break
type-checking for definitions using unsafe.Sizeof.
This has the side effect of changing the API output: constants with
different values across architectures (e.g., MaxInt) are now
individually listed per-arch. This actually makes the API file more
accurate, but does introduce a one-time discontinuity. These changes
have been integrated into the API files where the constants were added.
