uTLS: X25519Kyber768Draft00 hybrid post-quantum key agreement by cloudflare/go (#222)
* crypto/tls: Add hybrid post-quantum key agreement (#13) * import: client-side KEM from cloudflare/go * import: server-side KEM from cloudflare/go * fix: modify test to get rid of CFEvents. Note: uTLS does not promise any server-side functionality, and this change is made to be able to conduct unit tests which requires both side to be able to handle KEM Curves.

The hybrid post-quantum key exchanges uses plain X{25519,448} instead of HPKE, which we assume will be more likely to be adopted. The order is chosen to match CECPQ2. Not enabled by default. Adds CFEvents to detect `HelloRetryRequest`s and to signal which key agreement was used.

Limit this by restricting the size of RSA keys transmitted during handshakes to <= 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in circulation with keys larger than this, and all three appear to be test certificates that are not actively deployed. It is possible there are larger keys in use in private PKIs, but we target the web PKI, so causing breakage here in the interests of increasing the default safety of users of crypto/tls seems reasonable. Thanks to Mateusz Poliwczak for reporting this issue. Fixes CVE-2023-29409 * build: [ci skip] boring not included * fix: typo [ci skip] * docs: replenish readme [ci skip] replace old build status badge with new ones, bump up required version noted in docs, update developer contact to reflect current status. |

* crypto/tls: add support for Ed25519 certificates in TLS 1.2 and 1.3
Support for Ed25519 certificates was added in CL 175478, this wires them
up into the TLS stack according to RFC 8422 (TLS 1.2) and RFC 8446 (TLS 1.3).
RFC 8422 also specifies support for TLS 1.0 and 1.1, and I initially
implemented that, but even OpenSSL doesn't take the complexity, so I
just dropped it. It would have required keeping a buffer of the
handshake transcript in order to do the direct Ed25519 signatures. We
effectively need to support TLS 1.2 because it shares ClientHello
signature algorithms with TLS 1.3.
While at it, reordered the advertised signature algorithms in the rough
order we would want to use them, also based on what curves have fast
constant-time implementations.
Client and client auth tests changed because of the change in advertised
signature algorithms in ClientHello and CertificateRequest.

* all: remove PEM-encoded private keys from tests
Gerrit is complaining about pushes that affect these files
and forcing people to use -o nokeycheck, which defeats
the point of the check. Hide the keys from this kind of scan
by marking them explicitly as testing keys.
This is a little annoying but better than training everyone
who ever edits one of these test files to reflexively override
the Gerrit check.
The only remaining keys explicitly marked as private instead
of testing are in examples, and there's not much to do
about those. Hopefully they are not edited as much.

* crypto/tls: disable RSA-PSS in TLS 1.2 again
Signing with RSA-PSS can uncover faulty crypto.Signer implementations,
and it can fail for (broken) small keys. We'll have to take that
breakage eventually, but it would be nice for it to be opt-out at first.
TLS 1.3 requires RSA-PSS and is opt-out in Go 1.13. Instead of making a
TLS 1.3 opt-out influence a TLS 1.2 behavior, let's wait to add RSA-PSS
to TLS 1.2 until TLS 1.3 is on without opt-out.
Note that since the Client Hello is sent before a protocol version is
selected, we have to advertise RSA-PSS there to support TLS 1.3.
That means that we still support RSA-PSS on the client in TLS 1.2 for
verifying server certificates, which is fine, as all issues arise on the
signing side. We have to be careful not to pick (or consider available)
RSA-PSS on the client for client certificates, though.
We'd expect tests to change only in TLS 1.2:
* the server won't pick PSS to sign the key exchange
(Server-TLSv12-* w/ RSA, TestHandshakeServerRSAPSS);
* the server won't advertise PSS in CertificateRequest
(Server-TLSv12-ClientAuthRequested*, TestClientAuth);
* and the client won't pick PSS for its CertificateVerify
(Client-TLSv12-ClientCert-RSA-*, TestHandshakeClientCertRSAPSS,
Client-TLSv12-Renegotiate* because "R" requests a client cert).
Client-TLSv13-ClientCert-RSA-RSAPSS was updated because of a fix in the test.
This effectively reverts 88343530720a52c96b21f2bd5488c8fb607605d7.
Testing was made more complex by the undocumented semantics of OpenSSL's
-[client_]sigalgs (see openssl/openssl#9172).

seeing flakes on dragonfly (#29583).
But see also #19519, flakes due to the same assumption on FreeBSD

This CL rewrites localPipe to try a few times to get a matching pair
of connections on the dial and accept side.

* crypto/tls: remove TestVerifyHostnameResumed
Session resumption is not a reliable TLS behavior: the server can decide
to reject a session ticket for a number of reasons, or no reason at all.
This makes this non-hermetic test extremely brittle.
It's currently broken on the builders for both TLS 1.2 and TLS 1.3, and
I could reproduce the issue for TLS 1.3 only. As I was debugging it, it
started passing entirely on my machine.
In practice, it doesn't get us any coverage as resumption is already
tested with the recorded exchange tests, and TestVerifyHostname still
provides a smoke test checking that we can in fact talk TLS.

* crypto/tls: refactor certificate and signature algorithm logic
This refactors a lot of the certificate support logic to make it cleaner
and reusable where possible. These changes will make the following CLs
much simpler.
In particular, the heavily overloaded pickSignatureAlgorithm is gone.
That function used to cover both signing and verifying side, would work
both for pre-signature_algorithms TLS 1.0/1.1 and TLS 1.2, and returned
sigalg, type and hash.
Now, TLS 1.0/1.1 and 1.2 are differentiated at the caller, as they have
effectively completely different logic. TLS 1.0/1.1 simply use
legacyTypeAndHashFromPublicKey as they employ a fixed hash function and
signature algorithm for each public key type. TLS 1.2 is instead routed
through selectSignatureScheme (on the signing side) or
isSupportedSignatureAlgorithm (on the verifying side) and
typeAndHashFromSignatureScheme, like TLS 1.3.
On the signing side, signatureSchemesForCertificate was already version
aware (for PKCS#1 v1.5 vs PSS support), so selectSignatureScheme just
had to learn the Section 7.4.1.4.1 defaults for a missing
signature_algorithms to replace pickSignatureAlgorithm.
On the verifying side, pickSignatureAlgorithm was also checking the
public key type, while isSupportedSignatureAlgorithm +
typeAndHashFromSignatureScheme are not, but that check was redundant
with the one in verifyHandshakeSignature.
There should be no major change in behavior so far. A few minor changes
came from the refactor: we now correctly require signature_algorithms in
TLS 1.3 when using a certificate; we won't use Ed25519 in TLS 1.2 if the
client didn't send signature_algorithms; and we don't send
ec_points_format in the ServerHello (a compatibility measure) if we are
not doing ECDHE anyway because there are no mutually supported curves.
The tests also got simpler because they test simpler functions. The
caller logic switching between TLS 1.0/1.1 and 1.2 is tested by the
transcript tests.

* crypto/tls: select only compatible chains from Certificates
Now that we have a full implementation of the logic to check certificate
compatibility, we can let applications just list multiple chains in
Certificates (for example, an RSA and an ECDSA one) and choose the most
appropriate automatically.
NameToCertificate only maps each name to one chain, so simply deprecate
it, and while at it simplify its implementation by not stripping
trailing dots from the SNI (which is specified not to have any, see RFC
6066, Section 3) and by not supporting multi-level wildcards, which are
not a thing in the WebPKI (and in crypto/x509).
The performance of SupportsCertificate without Leaf is poor, but doesn't
affect current users. For now document that, and address it properly in
the next cycle. See #35504.
While cleaning up the Certificates/GetCertificate/GetConfigForClient
behavior, also support leaving Certificates/GetCertificate nil if
GetConfigForClient is set, and send unrecognized_name when there are no
available certificates.

This CL changes some unit test functions, making sure that these tests (and goroutines spawned during test) won't block.
Since they are just test functions, I use one CL to fix them all. I hope this won't cause trouble to reviewers and can save time for us.
There are three main categories of incorrect logic fixed by this CL:
1. Use testing.Fatal()/Fatalf() in spawned goroutines, which is forbidden by Go's document.
2. Channels are used in such a way that, when errors or timeout happen, the test will be blocked and never return.
3. Channels are used in such a way that, when errors or timeout happen, the test can return but some spawned goroutines will be leaked, occupying resource until all other tests return and the process is killed.

Clients have to reject any HelloRetryRequest message that doesn't lead
to a change in the ClientHello. Instead, we were rejecting any HRR that
didn't select an alternative group, even if it sent a cookie, which
would change the CH.
The good news is that I know of no TLS servers that use or need HRRs
exclusively for cookies (which are mostly useful in DTLS as a way to
verify the source address). The bad news is that we poisoned the
ecosystem as Go 1.12 to 1.14 will reject such HRRs. Oops, hopefully no
one needed this.
No tests because neither Go nor s_server support cookies. This would
presumably get covered once we integrate BoGo.

so they override what is saved in ClientSessionState. It is likely
that if the server is sending a different set of SCTs there is probably
a reason for doing so, such as a log being retired, or SCT validation

* crypto/tls: create certs w/o KeyEncipherment KU for non-RSA keys in generate_cert.go
Summary
The crypto/tls/generate_cert.go utility should only set the template
x509.Certificate's KeyUsage field to a value with the
x509.KeyUsageKeyEncipherment bits set when the certificate subject
public key is an RSA public key, not an ECDSA or ED25519 public key.
Background
RFC 5480 describes the usage of ECDSA elliptic curve subject keys with
X.509. Unfortunately while Section 3 "Key Usages Bits" indicates which
key usage bits MAY be used with a certificate that indicates
id-ecPublicKey in the SubjectPublicKeyInfo field it doesn't provide
guidance on which usages should *not* be included (e.g. the
keyEncipherment bit, which is particular to RSA key exchange). The same
problem is present in RFC 8410 Section 5 describing Key Usage Bits for
ED25519 elliptic curve subject keys.
There's an update to RFC 5480 in last call stage within the IETF LAMPS
WG, draft-ietf-lamps-5480-ku-clarifications-00. This update is meant
to clarify the allowed Key Usages extension values for certificates with
ECDSA subject public keys by adding:
> If the keyUsage extension is present in a certificate that indicates
> id-ecPublicKey as algorithm of AlgorithmIdentifier [RFC2986] in
> SubjectPublicKeyInfo, then following values MUST NOT be present:
>
> keyEncipherment; and
> dataEncipherment.
I don't believe there is an update for RFC 8410 in the works but I
suspect it will be clarified similarly in the future.
This commit updates generate_cert.go to ensure when the certificate
public key is ECDSA or ED25519 the generated certificate has the
x509.Certificate.KeyUsage field set to a value that doesn't include KUs
specific to RSA. For ECDSA keys this will adhere to the updated RFC 5480
language.

As part of #42026, these helpers from io/ioutil were moved to os.
(ioutil.TempFile and TempDir became os.CreateTemp and MkdirTemp.)
Update the Go tree to use the preferred names.
As usual, code compiled with the Go 1.4 bootstrap toolchain
and code vendored from other sources is excluded.
ReadDir changes are in a separate CL, because they are not a
simple search and replace.
For #42026.

* docs: clarify when APIs use context.Background.
The Go standard library retrofitted context support onto existing APIs
using context.Background and later offered variants that directly
supported user-defined context value specification. This commit makes
that behavior clear in documentation and suggests context-aware
alternatives if the user is looking for one.
An example motivation is supporting code for use in systems that expect
APIs to be cancelable for lifecycle correctness or load
shedding/management reasons, as alluded to in
https://blog.golang.org/context-and-structs.

* crypto/tls: add HandshakeContext method to Conn
Adds the (*tls.Conn).HandshakeContext method. This allows
us to pass the context provided down the call stack to
eventually reach the tls.ClientHelloInfo and
tls.CertificateRequestInfo structs.
These contexts are exposed to the user as read-only via Context()
methods.
This allows users of (*tls.Config).GetCertificate and
(*tls.Config).GetClientCertificate to use the context for
request scoped parameters and cancellation.
Replace uses of (*tls.Conn).Handshake with (*tls.Conn).HandshakeContext
where appropriate, to propagate existing contexts.

Simplified both tests significantly by removing logic for writing

* crypto/tls: make cipher suite preference ordering automatic
We now have a (well, two, depending on AES hardware support) universal
cipher suite preference order, based on their security and performance.
Peer and application lists are now treated as filters (and AES hardware
support hints) that are applied to this universal order.
This removes a complex and nuanced decision from the application's
responsibilities, one which we are better equipped to make and which
applications usually don't need to have an opinion about. It also lets
us worry less about what suites we support or enable, because we can be
confident that bad ones won't be selected over good ones.
This also moves 3DES suites to InsecureCipherSuites(), even if they are
not disabled by default. Just because we can keep them as a last resort
it doesn't mean they are secure. Thankfully we had not promised that
Insecure means disabled by default.
Notable test changes:
- TestCipherSuiteCertPreferenceECDSA was testing that we'd pick the
right certificate regardless of CipherSuite ordering, which is now
completely ignored, as tested by TestCipherSuitePreference. Removed.
- The openssl command of TestHandshakeServerExportKeyingMaterial was
broken for TLS 1.0 in CL 262857, but its golden file was not
regenerated, so the test kept passing. It now broke because the
selected suite from the ones in the golden file changed.
- In TestAESCipherReordering, "server strongly prefers AES-GCM" is
removed because there is no way for a server to express a strong
preference anymore; "client prefers AES-GCM and AES-CBC over ChaCha"
switched to ChaCha20 when the server lacks AES hardware; and finally
"client supports multiple AES-GCM" changed to always prefer AES-128
per the universal preference list.
* this is going back on an explicit decision from CL 262857, and
while that client order is weird and does suggest a strong dislike
for ChaCha20, we have a strong dislike for software AES, so it
didn't feel worth making the logic more complex
- All Client-* golden files had to be regenerated because the
ClientHello cipher suites have changed.
(Even when Config.CipherSuites was limited to one suite, the TLS 1.3
default order changed.)

Notably, objabi.GOEXPERIMENT is set to a comma-separated list of enabled experiments, but this may not be the string a user should set the GOEXPERIMENT environment variable to get that list of experiments: if an experiment is enabled by default but gets turned off by GOEXPERIMENT, then the string we report needs to include "no"+experiment to capture that default override. This complication also seeps into the version string we print for "go tool compile -V", etc. This logic is further complicated by the fact that it only wants to include an experiment string if the set of experiments varies from the default. This CL rethinks how we handle default-on experiments. Now that experiment state is all captured in a struct, we can simplify a lot of this logic. objabi.GOEXPERIMENT will be set based on the delta from the default set of experiments, which reflects what a user would actually need to pass on the command line. Likewise, we include this delta in the "-V" output, which simplifies this logic because if there's nothing to show in the version string, the delta will be empty.

It extends cmd/link to define _counters and _ecounters symbols so internal/fuzz can find the coverage counters. 2. It adds "trace" stub functions that implement the ABI expected by cmd/compile for comparison instrumentation. N.B., that -tags=libfuzzer should *not* be set, so that internal/fuzz's trace routines will be used instead of runtime's libfuzzer trampolines. Also, the current implementation doesn't support multi-module builds (i.e., compiling a Go program that spans multiple .so/.dll files). Presumably this isn't an issue, since "go test -fuzz" will need to recompile the binary with instrumentation anyway so it can make sure to always use a single-module build. But we can revisit this if necessary.

Peer and application lists are now treated as filters (and AES hardware support hints) that are applied to this universal order. This removes a complex and nuanced decision from the application's responsibilities, one which we are better equipped to make and which applications usually don't need to have an opinion about. It also lets us worry less about what suites we support or enable, because we can be confident that bad ones won't be selected over good ones. This also moves 3DES suites to InsecureCipherSuites(), even if they are not disabled by default. Just because we can keep them as a last resort it doesn't mean they are secure. Thankfully we had not promised that Insecure means disabled by default. Notable test changes: - TestCipherSuiteCertPreferenceECDSA was testing that we'd pick the right certificate regardless of CipherSuite ordering, which is now completely ignored, as tested by TestCipherSuitePreference. Removed. - The openssl command of TestHandshakeServerExportKeyingMaterial was broken for TLS 1.0 in CL 262857, but its golden file was not regenerated, so the test kept passing. It now broke because the selected suite from the ones in the golden file changed. - In TestAESCipherReordering, "server strongly prefers AES-GCM" is removed because there is no way for a server to express a strong preference anymore; "client prefers AES-GCM and AES-CBC over ChaCha" switched to ChaCha20 when the server lacks AES hardware; and finally "client supports multiple AES-GCM" changed to always prefer AES-128 per the universal preference list. * this is going back on an explicit decision from CL 262857, and while that client order is weird and does suggest a strong dislike for ChaCha20, we have a strong dislike for software AES, so it didn't feel worth making the logic more complex - All Client-* golden files had to be regenerated because the ClientHello cipher suites have changed.

Unfortunately, we can't store and use the coverage data for a given run of `go test` and re-use it the next time we fuzz, since the edges could have changed between builds. Instead, every entry in the seed corpus and the on-disk corpus is run by the workers before fuzzing begins, so that the coordinator can get the baseline coverage for what the fuzzing engine has already found (or what the developers have already provided). Users should run `go clean -fuzzcache` before using this change, to clear out any existing "interesting" values that were in the cache. Previously, every single non-crashing input was written to the on-disk corpus. Now, only inputs that actually expand coverage are written. This change includes a small hack in cmd/go/internal/load/pkg.go which ensures that the Gcflags that were explicitly set in cmd/go/internal/test/test.go don't get cleared out.

Ideally counters would be deterministic, as there are many advanced fuzzing strategies that require mutating the input while maintaining static coverage. The simplest way to mitigate this noise is to capture the coverage counters as closely as possible to the invocation of the fuzz target in the testing package. In order to do this add a new function which captures the current values of the counters, SnapshotCoverage. This function copies the current counters into a static buffer, coverageSnapshot, which workerServer.fuzz can then inspect when it comes time to check if new coverage has been found. This method is not foolproof. As the fuzz target is called in a goroutine, harness code can still cause counters to be incremented while the target is being executed. Despite this we do see significant reduction in churn via this approach. For example, running a basic target that causes strconv to be instrumented for 500,000 iterations causes ~800 unique sets of coverage counters, whereas by capturing the counters closer to the target we get ~40 unique sets. It may be possible to make counters completely deterministic, but likely this would require rewriting testing/F.Fuzz to not use tRunner in a goroutine, and instead use it in a blocking manner (which I couldn't figure out an obvious way to do), or by doing something even more complex.
