linker seems to require LLVMgold.so and can't find it. I'm not really

Since all the platforms now support O_DIRECTORY flag for open, it can be
used to (together with O_NOFOLLOW) to ensure we open a directory, thus
eliminating the need to call stat before open. This fixes the symlink race,
when a directory is replaced by a symlink in between stat and open calls.

While at it, rename openFdAt to openDirAt, because this function is (and was)
meant for directories only.

NOTE Solaris supports O_DIRECTORY since before Solaris 11 (which is the
only version Go supports since supported version now), and Illumos
always had it. The only missing piece was O_DIRECTORY flag value, which

11 months agoiter: deflake TestPull by letting exiting goroutines finish
Michael Anthony Knyszek [Thu, 23 May 2024 20:26:02 +0000 (20:26 +0000)]
iter: deflake TestPull by letting exiting goroutines finish

Currently TestPull is flaky because goroutines spawned to run subtests
exit asynchronously when they finish and TestPull has explicit checks
for the number of existing goroutines.

This is pretty much only a problem between subtests executing, because
within each subtest the coroutine goroutine spawned for iter.Pull always
exits fully synchronously before the final `next` or `stop` returns.

So, we can resolve the problem by ensuring the first goroutine count the
test takes likely doesn't contain any exiting goroutines. The trick is
to set GOMAXPROCS=1 and spin in runtime.Gosched until the number of
goroutines stabilizes to some reasonable degree (we pick 100 consecutive
iterations; there are only a handful of possible goroutines that can
run, so this is giving that handful around 20 chances to actually run to
completion).

When running TestPull under stress2, this issue is easily reproducible
before this CL. After this CL, it no longer reproduces under these
conditions.

Fixes #66017.

net/http: remove TestTransportDialCancelRace

This test was added to cover a specific race condition
in request cancellation, applying only to the deprecated
Transport.CancelRequest cancellation path. The test
assumes that canceling a request at the moment
persistConn.RoundTrip begins guarantees that it will
be canceled before being sent.

This does not apply to the newer forms of canceling
a request: Request.Cancel and context-based cancellation
both send the cancel signal on a channel, and do not
check for cancellation before sending a request.

A recent refactoring unified the implementation
of cancellation, so the Transport.CancelRequest
path now translates into context-based cancellation
internally. This makes this test flaky, since
sometimes the request completes before we read
from the context's done channel.

Drop the test entirely. It's verifying the fix
for a bug in a code path which no longer exists,
and the property that it's testing for (canceling
a request at a very specific point in the internal
request flow) is not interesting.

cmd/compile: intrinsify atomic And/Or on arm64

The atomic And/Or operators were added by the CL 528797,
the compiler does not intrinsify them, this CL does it for
arm64.

Also, for the existing atomicAnd/Or operations, the updated
value are not used, but at that time we need a register to
temporarily hold it. Now that we have v.RegTmp, the new value
is not needed anymore. This CL changes it.

The other change is that the existing operations don't use their
result, but now we need the old value and not the new value for
the result.

And this CL alias all of the And/Or operations into sync/atomic
package.

crypto/tls: add ech client support

This CL adds a (very opinionated) client-side ECH implementation.

In particular, if a user configures a ECHConfigList, by setting the
Config.EncryptedClientHelloConfigList, but we determine that none of
the configs are appropriate, we will not fallback to plaintext SNI, and
will instead return an error. It is then up to the user to decide if
they wish to fallback to plaintext themselves (by removing the config
list).

Additionally if Config.EncryptedClientHelloConfigList is provided, we
will not offer TLS support lower than 1.3, since negotiating any other
version, while offering ECH, is a hard error anyway. Similarly, if a
user wishes to fallback to plaintext SNI by using 1.2, they may do so
by removing the config list.

With regard to PSK GREASE, we match the boringssl  behavior, which does
not include PSK identities/binders in the outer hello when doing ECH.

If the server rejects ECH, we will return a ECHRejectionError error,
which, if provided by the server, will contain a ECHConfigList in the
RetryConfigList field containing configs that should be used if the user
wishes to retry. It is up to the user to replace their existing
Config.EncryptedClientHelloConfigList with the retry config list.

11 months agoruntime: skip tracing events that would cause reentrancy
Michael Anthony Knyszek [Wed, 22 May 2024 20:00:02 +0000 (20:00 +0000)]
runtime: skip tracing events that would cause reentrancy

Some of the new experimental events added have a problem in that they
might be emitted during stack growth. This is, to my knowledge, the only
restriction on the tracer, because the tracer otherwise prevents
preemption, avoids allocation, and avoids write barriers. However, the
stack can grow from within the tracer. This leads to
tracing-during-tracing which can result in lost buffers and broken event
streams. (There's a debug mode to get a nice error message, but it's
disabled by default.)

This change resolves the problem by skipping writing out these new
events. This results in the new events sometimes being broken (alloc
without a free, free without an alloc) but for now that's OK. Before the
freeze begins we just want to fix broken tests; tools interpreting these
events will be totally in-house to begin with, and if they have to be a
little bit smarter about missing information, that's OK. In the future
we'll have a more robust fix for this, but it appears that it's going to
require making the tracer fully reentrant. (This is not too hard; either
we force flushing all buffers when going reentrant (which is actually
somewhat subtle with respect to event ordering) or we isolate down just
the actual event writing to be atomic with respect to stack growth. Both
are just bigger changes on shared codepaths that are scary to land this
late in the release cycle.)

11 months agoruntime: lower mutex contention test expectations
Rhys Hiltner [Wed, 22 May 2024 18:53:36 +0000 (11:53 -0700)]
runtime: lower mutex contention test expectations

As of https://go.dev/cl/586796, the runtime/metrics view of internal
mutex contention is sampled at 1 per gTrackingPeriod, rather than either
1 (immediately prior to CL 586796) or the more frequent of
gTrackingPeriod or the mutex profiling rate (Go 1.22). Thus, we no
longer have a real lower bound on the amount of contention that
runtime/metrics will report. Relax the test's expectations again.

For #64253

11 months agoruntime: write out a batch with alignment info for traceallocfree
Michael Anthony Knyszek [Mon, 20 May 2024 20:31:36 +0000 (20:31 +0000)]
runtime: write out a batch with alignment info for traceallocfree

Currently the traceallocfree experiment is missing info in the trace for
interpeting the produced events. Most notably, the base heap address is
missing. While not technically necessary, it is useful for getting an
accurate picture of the program's memory layout, and will be useful for
future trace experiments. Since we want to emit a batch for this, we
should also emit a batch for all the alignment info that's used to
compress the addresses (IDs) produced for the alloc/free events.

This CL distinguishes the different formats of the experimental batches
(note that there's already batches containing type information in this
experiment) by putting a byte at the beginning of each experimental
batch indicating its format.

cmd/compile/internal/ssa: reintroduce ANDconst opcode on PPC64

This allows more effective conversion of rotate and mask opcodes
into their CC equivalents, while simplifying the first lowering
pass.

This was removed before the latelower pass was introduced to fold
more cases of compare against zero. Add ANDconst to push the
conversion of ANDconst to ANDCCconst into latelower with the other
CC opcodes.

This also requires introducing RLDICLCC to prevent regressions
when ANDconst is converted to RLDICL then to RLDICLCC and back
to ANDCCconst when possible.
