Changes were made in 1554ac3b5f to provide
a mechanism for the CLI to notify running plugin processes that they
should exit, in order to improve the general CLI/plugin UX. The current
implementation boils down to:
1. The CLI creates a socket
2. The CLI executes the plugin
3. The plugin connects to the socket
4. (When) the CLI receives a termination signal, it uses the socket to
notify the plugin that it should exit
5. The plugin's gets notified via the socket, and cancels it's `cmd.Context`,
which then gets handled appropriately
This change works in most cases and fixes the issue it sets out to solve
(see: https://github.com/docker/compose/pull/11292) however, in the case
where the user has a TTY attached and the plugin is not already handling
received signals, steps 4+ changes:
4. (When) the CLI receives a termination signal, before it can use the
socket to notify the plugin that it should exit, the plugin process
also receives a signal due to sharing the pgid with the CLI
Since we now have a proper "job control" mechanism, we can simplify the
scenarios by executing the plugins with their own process group id,
thereby removing the "double notification" issue and making it so that
plugins can handle the same whether attached to a TTY or not.
In order to make this change "plugin-binary" backwards-compatible, in
the case that a plugin does not connect to the socket, the CLI passes
the signal to the plugin process.

Previously, long lived CLI plugin processes weren't
properly handled
(see: https://github.com/docker/cli/issues/4402)
resulting in plugin processes being left behind
running, after the CLI process exits.
This commit changes the plugin handling code to open
an abstract unix socket before running the plugin and
passing it to the plugin process, and changes the
signal handling on the CLI side to close this socket
which tells the plugin that it should exit.
This implementation makes use of sockets instead of
simply setting PDEATHSIG on the plugin process
so that it will work on both BSDs, assorted UNIXes
and Windows.

Fixes#4648
Make it easier to specify IPv6 addresses in the '--add-host' option by
permitting 'host=ip' in addition to 'host:ip', and allowing square
brackets around the address.
For example:
--add-host=my-hostname:127.0.0.1
--add-host=my-hostname:::1
--add-host=my-hostname=::1
--add-host=my-hostname:[::1]
To avoid compatibility problems, the CLI will replace an '=' separator
with ':', and strip brackets, before sending the request to the API.

[security] Go 1.21.5 and Go 1.20.12 are released
Hello gophers,
We have just released Go versions 1.21.5 and 1.20.12, minor point releases.
These minor releases include 3 security fixes following the security policy:
- net/http: limit chunked data overhead
A malicious HTTP sender can use chunk extensions to cause a receiver
reading from a request or response body to read many more bytes from
the network than are in the body.
A malicious HTTP client can further exploit this to cause a server to
automatically read a large amount of data (up to about 1GiB) when a
handler fails to read the entire body of a request.
Chunk extensions are a little-used HTTP feature which permit including
additional metadata in a request or response body sent using the chunked
encoding. The net/http chunked encoding reader discards this metadata.
A sender can exploit this by inserting a large metadata segment with
each byte transferred. The chunk reader now produces an error if the
ratio of real body to encoded bytes grows too small.
Thanks to Bartek Nowotarski for reporting this issue.
This is CVE-2023-39326 and Go issue https://go.dev/issue/64433.
- cmd/go: go get may unexpectedly fallback to insecure git
Using go get to fetch a module with the ".git" suffix may unexpectedly
fallback to the insecure "git://" protocol if the module is unavailable
via the secure "https://" and "git+ssh://" protocols, even if GOINSECURE
is not set for said module. This only affects users who are not using
the module proxy and are fetching modules directly (i.e. GOPROXY=off).
Thanks to David Leadbeater for reporting this issue.
This is CVE-2023-45285 and Go issue https://go.dev/issue/63845.
- path/filepath: retain trailing \ when cleaning paths like \\?\c:\
Go 1.20.11 and Go 1.21.4 inadvertently changed the definition of the
volume name in Windows paths starting with \\?\, resulting in
filepath.Clean(\\?\c:\) returning \\?\c: rather than \\?\c:\ (among
other effects). The previous behavior has been restored.
This is an update to CVE-2023-45283 and Go issue https://go.dev/issue/64028.

[security] Go 1.21.4 and Go 1.20.11 are released
Hello gophers,
We have just released Go versions 1.21.4 and 1.20.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- path/filepath: recognize `\??\` as a Root Local Device path prefix.
On Windows, a path beginning with `\??\` is a Root Local Device path equivalent
to a path beginning with `\\?\`. Paths with a `\??\` prefix may be used to
access arbitrary locations on the system. For example, the path `\??\c:\x`
is equivalent to the more common path c:\x.
The filepath package did not recognize paths with a `\??\` prefix as special.
Clean could convert a rooted path such as `\a\..\??\b` into
the root local device path `\??\b`. It will now convert this
path into `.\??\b`.
`IsAbs` did not report paths beginning with `\??\` as absolute.
It now does so.
VolumeName now reports the `\??\` prefix as a volume name.
`Join(`\`, `??`, `b`)` could convert a seemingly innocent
sequence of path elements into the root local device path
`\??\b`. It will now convert this to `\.\??\b`.
This is CVE-2023-45283 and https://go.dev/issue/63713.
- path/filepath: recognize device names with trailing spaces and superscripts
The `IsLocal` function did not correctly detect reserved names in some cases:
- reserved names followed by spaces, such as "COM1 ".
- "COM" or "LPT" followed by a superscript 1, 2, or 3.
`IsLocal` now correctly reports these names as non-local.
This is CVE-2023-45284 and https://go.dev/issue/63713.

"By default" implies that this is something which could be
disabled for an individual `docker exec` call. This doesn't seem
to be the case, so removing the "by default" part would make
these docs clearer to me.

- updates fc6976db45
- updates 74bace156c
Commit fc6976db45 introduced support for the
`bind-recursive` option on `--mount`, and deprecated the `bind-nonrecursive`
option. Unlike `bind-nonrecursive` boolean, the `bind-recursive` option
accepts a string value with multiple options.
For convenience, the `bind-recursive` option also was made to accept boolean
values (true/false, 1/0). However, as the option works as the _reverse_ of
`bind-nonrecursive` (`bind-nonrecursive=true` === `bind-recursive=false`),
the new option won't be a "drop-in" replacement, and having more options
to choose from may only be adding more complexity / cognitive overload.
This patch removes support for boolean values; if we see a need to add
support for boolean values in future, it would be trivial to add back this
functionality.
