Since we can't feasibly add detail on the net/http side without

As an alternative, validType could mark invalid *Named types

cmd/compile: support libFuzzer value profiling mode for integer compares
libFuzzer provides a special mode known as “value profiling” in which it
tracks the bit-wise progress made by the fuzzer in satisfying tracked
comparisons. Furthermore, libFuzzer uses the value of the return address
in its hooks to distinguish the progress for different comparisons.
The original implementation of the interception for integer comparisons
in Go simply called the libFuzzer hooks from a function written in Go
assembly. The libFuzzer hooks thus always see the same return address
(i.e., the address of the call instruction in the assembly snippet) and
thus can’t distinguish individual comparisons anymore. This drastically
reduces the usefulness of value profiling.
This is fixed by using an assembly trampoline that injects synthetic but
valid return addresses on the stack before calling the libFuzzer hook,
otherwise preserving the calling convention of the respective platform
(for starters, x86_64 Windows or Unix). These fake PCs are generated
deterministically based on the location of the compare instruction in
the IR representation.

Currently, physical-page-aligned allocations for stacks (where the
physical page size is greater than the runtime page size) first
overallocates some memory, then frees the unaligned portions back to the
heap.
However, because allocating via h.pages.alloc causes scavenged bits to
get cleared, we need to account for that memory correctly in heapFree
and heapReleased. Currently that is not the case, leading to throws at
runtime.
Trying to get that accounting right is complicated, because information
about exactly which pages were scavenged needs to get plumbed up.
Instead, find the oversized region first, and then only allocate the
aligned part. This avoids any accounting issues.
However, this does come with some performance cost, because we don't
update searchAddr (which is safe, it just means the next allocation
potentially must look harder) and we skip the fast path that
h.pages.alloc has for simplicity.

2- Newly covered blocks are now properly reported as new coverage by
libFuzzer, not only as new features.
3- The NeverZero strategy is used to ensure that coverage counters

issues encountered when fuzzing loops with iteration counts that

runtime: test alignment of fields targeted by 64-bit atomics
Make sure that all the targets of 64-bit atomic operations
are actually aligned to 8 bytes. This has been a source of
bugs on 32-bit systems. (e.g. CL 399754)
The strategy is to have a simple test that just checks the
alignment of some explicitly listed fields and global variables.
Then there's a more complicated test that makes sure the list
used in the simple test is exhaustive. That test has some
limitations, but it should catch most cases, particularly new
uses of atomic operations on new or existing fields.
Unlike a runtime assert, this check is free and will catch
accesses that occur even in very unlikely code paths.

cmd/gofmt: use SkipObjectResolution with -s as well
The "simplify" feature used go/ast's object tracking in only one place -
to replace s[a:len(s)] with s[a:].
Using go/ast.Object did allow us to not simplify code like:
len := func(s []int) int { ... }
s = s[a:len(s)]
The existing code already noted the limitation with that approach,
such as "len" being redeclared in a different file in the same package.
Since go/ast's object tracking is file-based and very basic,
it wouldn't work with edge cases like those.
The reasoning is that redeclaring len and abusing it that way is
extremely unlikely, and hasn't been a problem in about a decade now.
I reason that the same applies to len being redeclared in the same file,
so we should be able to safely remove the use of go/ast.Object here.
Per https://go.dev/cl/401454, this makes "gofmt -s" about 5% faster.
If we ever wanted to truly get rid of false positive simplifications,
I imagine we'd want to reimplement the feature under go/analysis,
which is able to fully typecheck packages and suggest edits.
That seems unnecessary at this point, but we can always course correct
in the presumably unlikely scenario that users start reporting bugs.
See #46485.

misc/cgo/testplugin: set the package name in TestIssue19534
The fix for #19534 (in CL 40994) adjusted escaping in the
dynamically-linked name lookup logic for the plugin package. However,
the regression test added for it incorrectly included quotes within
the -ldflags flag, causing the flag to inadvertently be ignored.
Possibly in that same CL or possibly at some other point, the
condition that the test thought it was checking stopped working: the
dynamic lookup used the path passed to ldflags, but the object file
actually contained the symbol indexed by the original package name.
Ideally we should stop mucking around with ldflags in this test and
run 'go build' from a suitably-named directory instead, to mimic the
actual conditions in which the original bug was reported. For now, as
a more targeted fix, we can pass the '-p' flag to the compiler to
adjust the package path used at compile time to match the one that
will be set at link time.

correctly. There have been flaky failures on the builder (probably
due to OS scheduling delays). Increase the threshold to make it
less flaky. The gap would be much bigger if the scheduler doesn't
work correctly.
For the long term maybe it is better to test it more directly
with the scheduler, e.g. with scheduler instrumentation.
May fix #52207.

net/http/cookiejar: allow cookies with an IP address in the domain attribute
A set domain attribute in a cookie in a Set-Cookie header is intended to
create a domain cookie, i.e. a cookie that is not only sent back to the
domain the Set-Cookie was received from, but to all subdomains thereof
too. Sometimes people set this domain attribute to an IP address. This
seems to be allowed by RFC 6265 albeit it's not really sensible as there
are no "subdomains" of an IP address.
Contemporary browsers allow such cookies, currently Jar forbids them.
This CL allows to persist such cookies in the Jar and send them back
again in subsequent requests. Jar allows those cookies that all
contemporary browsers allow (not all browsers behave the same and none
seems to conform to RFC 6265 in regards to these cookies, see below).
The following browsers in current version) were tested:
- Chrome (Mac and Windows)
- Firefox (Mac and Windows)
- Safari (Mac)
- Opera (Mac)
- Edge (Windows)
- Internet Explorer (Windows)
- curl (Mac, Linux)
All of them allow a cookie to be set via the following HTTP header if
the request was made to e.g. http://35.206.97.83/ :
Set-Cookie: a=1; domain=35.206.97.83
They differ in handling a leading dot "." before the IP address as in
Set-Cookie: a=1; domain=.35.206.97.83
sets a=1 only in curl and in Internet Explorer, the other browsers just
reject such cookies.
As far as these internals can be observed the browsers do not treat such
cookies as domain cookies but as host cookies. RFC 6265 would require to
treat them as domain cookies; this is a) nonsensical and b) doesn't make
an observable difference. As we do not expose Jar entries and their
HostOnly flag it probably is still okay to claim that Jar implements a
RFC 6265 cookie jar.
RFC 6265 would allow cookies with dot-prefixed domains like
domain=.35.206.97.83 but it seems as if this feature of RFC 6265 is not
used in real life and not requested by users of package cookiejar (probably
because it doesn't work in browsers) so we refrain from documenting this
detail.

Since the docs already mentioned that they may be unstable across

If the status code is in the 1xx range, the current content of the header map

because the headers must also be included in the final response.
The Chrome and Fastly teams are starting a large-scale experiment to measure
