The eventually-consistent nature of NetworkDB means we cannot depend on
events being received in the same order that they were sent. Nor can we
depend on receiving events for all intermediate states. It is possible
for a series of entry UPDATEs, or a DELETE followed by a CREATE with the
same key, to get coalesced into a single UPDATE event on the receiving
node. Watchers of NetworkDB tables therefore need to be prepared to
gracefully handle arbitrary UPDATEs of a key, including those where the
new value may have nothing in common with the previous value.
The libnetwork controller naively handled events for endpoint_table
assuming that an endpoint leave followed by a rejoin of the same
endpoint would always be expressed as a DELETE event followed by a
CREATE. It would handle a coalesced UPDATE as a CREATE, adding a new
service binding without removing the old one. This would
have various side effects, such as having the "transient state" of
having multiple conflicting service bindings where more than one
endpoint is assigned an IP address never settling.

Windows and Linux overlay driver instances are interoperable, working
from the same NetworkDB table for peer discovery. As both drivers
produce and consume serialized data through the table, they both need to
have a shared understanding of the shape and semantics of that data.
The Windows overlay driver contains a duplicate copy of the protobuf
definitions used for marshaling and unmarshaling the NetworkDB peer
entries for dubious reasons. It gives us the flexibility to have the
definitions diverge, which is only really useful for shooting ourselves
in the foot.

The concurrency control in the overlay driver is logically unsound.
While the use of mutexes is sufficient to prevent data races --
violations of the Go memory model -- many operations which need to be
atomic are performed with unbounded concurrency.
Overhaul the use of locks in the overlay network driver. Implement sound
locking at the network granularity: operations may proceed concurrently
iff they are being applied to distinct networks. Push the responsibility
of locking up to the code which calls methods or accesses struct fields
to avoid deadlock situations like we had previously with
d.initSandboxPeerDB() and to make the code easier to reason about.
Each overlay network has a distinct peer db. The NetworkDB watch for the
overlay peer table for the network will only start after
(*driver).CreateNetwork returns and will be stopped before libnetwork
calls (*driver).DeleteNetwork, therefore the lifetime of the peer db for
a network is constrained to the lifetime of the network itself. Yet the
peer db for a network is tracked in a dedicated map, separately from the
network objects themselves. This has resulted in a parallel set of
mutexes to manage concurrency of the peer db distinct from the mutexes
for the driver and networks. Move the peer db for a network into a field
of the network struct and guard it from concurrent access using the
per-network lock. Move the methods for manipulating the peer db into the
network struct so that the methods can only be called if the caller has
a reference to the network object.
Network creation and deletion are synchronized using the driver-scope
mutex, but some of the kernel programming is performed outside of the
critical section. It is possible for network deletion to race with
recreating the network, interleaving the kernel programming for the
network creation and deletion, resulting in inconsistent kernel state.
Parallelize network creation and deletion soundly. Use a double-checked
locking scheme to soundly handle the case of concurrent CreateNetwork
and DeleteNetwork for the same network id without blocking operations
on other networks. Synchronize operations on a network so that
operations on the network such as adding a neighbor to the peer db are
performed atomically, not interleaved with deleting the network.

There is a dedicated mutex for synchronizing access to the encrMap.
Separately, the main driver mutex is used for synchronizing access to
the encryption keys. Their use is sufficient to prevent data races (if
used correctly, which is not the case) but not logical race conditions.
Programming the encryption parameters for a peer can race with
encryption keys being updated, which could lead to inconsistencies
between the parameters programmed into the kernel and the desired state.
Introduce a new mutex for synchronizing encryption operations. Use that
mutex to synchronize access to both encrMap and keys. Handle encryption
key updates in a critical section so they can no longer be interleaved
with kernel programming of encryption parameters.

The IPsec encryption parameters (Security Association Database and
Security Policy Database entries) for a particular overlay network peer
(VTEP) are shared global state as they have to be programmed into the
root network namespace. The same parameters are used when encrypting
VXLAN traffic to a particular VTEP for all overlay networks. Deleting
the entries for a VTEP will break encryption to that VTEP across all
encrypted overlay networks, therefore the decision of when to delete the
entries must take the state of all overlay networks into account.
Unfortunately this is not the case.
The overlay driver uses local per-network state to decide when to
program and delete the parameters for a VTEP. In practice, the
parameters for all VTEPs participating in an encrypted overlay network
are deleted when the network is deleted. Encryption to that VTEP over
all other active encrypted overlay networks would be broken until some
other incidental peerDB event triggered a re-programming of the
parameters for that VTEP.
Change the setupEncryption and removeEncryption functions to be
reference-counted. The removeEncryption function needs to be called the
same number of times as addEncryption before the parameters are deleted
from the kernel.

The overlay driver assumes that the peer table in NetworkDB will always
converge to a 1:1:1 mapping from peer endpoint IP address to MAC address
to VTEP. While this currently holds true in practice most of the time,
it is not an invariant and there are ways that users can violate this
assumption.
The driver detects whether peer entries conflict with each other by
matching up (IP, MAC) tuples. In the common case this works out fine as
the MAC address for an endpoint is generally derived from the assigned
IP address. If an IP address gets reassigned to a container on another
node the MAC address will follow, so the driver's conflict resolution
logic will behave as intended. However users may explicitly configure
the MAC address for a container's network endpoints. If an IP address
gets reassigned from a container with an auto-generated MAC address to a
container with a manually-configured MAC, or vice versa, the driver
would not detect the conflict as the (IP, MAC) tuples won't match up. It
would attempt to program the kernel's neighbor table with two
conflicting MAC addresses for one IP, which will fail. And since it
does not realize that there is a conflict, the driver won't reprogram
the kernel from the remaining entry when the other entry is deleted.
The assumption that only one IP address may resolve to a given MAC
address is violated if multiple IP addresses are assigned to an
endpoint. This rarely comes up in practice today as the overlay driver
only supports IPv4 single-stack connectivity for endpoints. If multiple
distinct peer entries exist with the same MAC address, the driver will
delete the MAC->VTEP mapping from the kernel's forwarding database when
any entry is deleted, even if other entries remain active. This
limitation is one of the biggest obstacles in the way of supporting IPv6
and dual-stack connectivity for endpoints attached to overlay networks.
Modify the peer db logic to correctly handle the cases where peer
entries have non-unique MAC or VTEP values. Treat any set of entries
with non-unique IP addresses as a conflict, irrespective of the entries'
MAC addresses. Maintain a reference count of forwarding database entries
and only delete the MAC->VTEP mapping from the kernel when there are no
longer any neighbor entries which resolve to that MAC.

Since it is not meaningful to add or remove encryption between the local
node and itself, the isLocal parameter is redundant. Setting up
encryption for all network peers is now invoked by calling
checkEncryption(nid, netip.Addr{}, true)
Calling checkEncryption with isLocal=true, add=false is now more
explicitly a no-op. It always was effectively a no-op, but that was not
easy to spot by inspection. In the world with the isLocal flag,
calls to checkEncryption where isLocal=true and add=false would have rIP
set to d.advertiseAddr. In other words, it was a request to remove
encryption parameters between the local peer and itself if peerDB had no
remote-peer entries for the network. So either the call would do
nothing, or it would remove encryption parameters that aren't used for
anything. Now the equivalent call always does nothing.

The VTEP value for a peer in peerDB is only accurate for a remote peer.
The VTEP for a local peer would be the driver's advertise address, which
is not necessarily constant for the lifetime of the driver instance.
The VTEP values persisted in the peerDB entries for local peers could be
stale or missing if not kept in sync with the advertise address. And the
peerDB could get polluted with duplicate entries for local peers if the
advertise address was to change, as entries which differ only by VTEP
are considered distinct by SetMatrix. Persisting the advertise address
as the VTEP for local peers creates lots of problems that are not easy
to solve.
Stop persisting the VTEP for local peers in peerDB. Any code that needs
to know the VTEP for local peers can look that up from the source of
truth: the driver's advertise address. Use the lack of a VTEP in peerDB
entries to signify local peers, making the isLocal flag redundant.

The overlay driver's checkEncryption function configures the IPSec
parameters for the VXLAN tunnels to peer nodes. When called with
isLocal=true, it configures encryption for all peer nodes with at least
one peerDB entry. Since the local peers are also included in the peerDB,
it needs to filter those entries out. It does so by filtering out any
peer entries whose VTEP address is equal to the current local advertise
address. Trouble is, the local advertise address is not necessarily
constant. The driver tries to handle this case by calling
peerDBUpdateSelf() when the advertise address changes. This function
iterates through the peerDB and tries to update the VTEP address for all
local peer entries, but it does not actually do anything: it mutates a
temporary copy of the entry which is not persisted back into the peerDB.
(It used to be functional, but was broken when the peerDB was extended
to use SetMatrix.) So there may be cases where local peer entries are
not filtered out properly, resulting in spurious encryption parameters
being programmed into the kernel.
Filter out local peers when walking the peerDB by filtering on whether
the entry has the isLocal flag set. Remove the no-op code which attempts
to update local entries in the peerDB. No other code takes any interest
in the VTEP value for isLocal peer entries.

The netip types are really useful for tracking state in the overlay
driver as they are hashable, unlike net.IP and friends, making them
directly useable as map keys. Converting between netip and net types is
fairly trivial, but fewer conversions is more ergonomic.
The NetworkDB entries for the overlay peer table encode the IP addresses
as strings. We need to parse them to some representation before
processing them further. Parse directly into netip types and pass those
values around to cut down on the number of conversions needed.
The peerDB needs to marshal the keys and entries to structs of hashable
values to be able to insert them into the SetMatrix. Use netip.Addr in
peerEntry so that peerEntry values can be directly inserted into the
SetMatrix without conversions. Use a hashable struct type as the
SetMatrix key to avoid having to marshal the whole struct to a string
and parse it back out.
Use netip.Addr as the map key for the driver's encryption map so the
values do not need to be converted to and from strings. Change the
encryption configuration methods to take netip types so the peerDB code
can pass netip values directly.

When a node leaves a network, all entries owned by that node are
implicitly deleted. The other NetworkDB nodes handle the leave by
setting the deleted flag on the entries owned by the left node in their
local stores. This behaviour is problematic as it results in two
conflicting entries with the same Lamport timestamp propagating
through the cluster.
Consider two NetworkDB nodes, A, and B, which are both joined to some
network. Node A in quick succession leaves the network, immediately
rejoins it, then creates an entry. If Node B processes the
entry-creation event first, it will add the entry to its local store
then set the deleted flag upon processing the network-leave. No matter
how many times B bulk-syncs with A, B will ignore the live entry for
having the same timestamp as its local tombstone entry. Once this
situation occurs, the only way to recover is for the entry to get

There is no need for a node to store forged tombstones for another
node's entries. All nodes will purge the entries naturally when they
process the network-leave or node-leave event. Simply delete the
non-owned entries from the local store so there is no inconsistent state
to interfere with convergence when nodes rejoin a network. Have nodes
update their local store with tombstones for entries when leaving a
network so that after a rapid leave-then-rejoin the entry deletions
propagate to nodes which may have missed the leave event.

NetworkDB's JoinNetwork function enqueues a message onto a
TransmitLimitedQueue while holding the NetworkDB mutex locked for
writing. The TransmitLimitedQueue has its own synchronization;
it locks its mutex when enqueueing a message. Locking order:
1. (NetworkDB).RWMutex.Lock()
2. (TransmitLimitedQueue).mu.Lock()
NetworkDB's gossip periodic task calls GetBroadcasts on the same
TransmitLimitedQueue to retrieve the enqueued messages. GetBroadcasts
invokes the queue's NumNodes callback while the mutex is locked. The
NumNodes callback function that NetworkDB sets locks the NetworkDB mutex
for reading to take the length of the nodes map. Locking order:
1. (TransmitLimitedQueue).mu.Lock()
2. (NetworkDB).RWMutex.RLock()
If one goroutine calls GetBroadcasts on the queue concurrently with
another goroutine calling JoinNetwork on the NetworkDB, the goroutines
may deadlock due to the lock inversion.
Fix the deadlock by caching the number of nodes in an atomic variable so
that the NumNodes callback can load the value without blocking or
violating Go's memory model. And fix a similar deadlock situation with
the table-event broadcast queues.

With rejoinClusterBootStrap fixed in tests, split clusters should
reliably self-heal in tests as well as production. Work around the other
source of flakiness in TestNetworkDBIslands: timing out waiting for a
failed node to transition to gracefully left. This flake happens when
one of the leaving nodes sends its NodeLeft message to the other leaving
node, and the second is shut down before it has a chance to rebroadcast
the message to the remaining nodes. The proper fix would be to leverage
memberlist's own bookkeeping instead of duplicating it poorly with user
messages, but doing so requires a change in the memberlist module.
Instead have the test check that the sum of failed+left nodes is
expected instead of waiting for all nodes to have failed==3 && left==0.

The rejoinClusterBootStrap periodic task rejoins with the bootstrap
nodes if none of them are members of the cluster. It correlates the
cluster nodes with the bootstrap list by comparing IP addresses,
ignoring ports. In normal operation this works out fine as every node
has a unique IP address, but in unit tests every node listens on a
distinct port of 127.0.0.1. This situation causes the check to
incorrectly filter out all nodes from the list, mistaking them for the
local node.
Filter out the local node using pointer equality of the *node to avoid
any ambiguity. Correlate the remote nodes by IP:port so that the check
behaves the same in tests and in production.

A network node is responsible for both broadcasting table events for
entries it owns and for rebroadcasting table events from other nodes it
has received. Table events to be broadcast are added to a single queue
per network, including events for rebroadcasting. As the memberlist
TransmitLimitedQueue is (to a first approximation) LIFO, a flood of
events from other nodes could delay the broadcasting of
locally-generated events indefinitely. Prioritize broadcasting local
events by splitting up the queues and only pulling from the rebroadcast
queue if there is free space in the gossip packet after draining the
local-broadcast queue.

NetworkDB uses a muli-dimensional map of struct network to keep track of
network attachments for both remote nodes and the local node. Only a
subset of the struct fields are used for remote nodes' network
attachments. The tableBroadcasts pointer field in particular is
always initialized for network values representing local attachments
(read: nDB.networks[nDB.config.NodeID]) and always nil for remote
attachments. Consequently, unnecessary defensive nil-pointer checks are
peppered throughout the code despite the aforementioned invariant.
Enshrine the invariant that tableBroadcasts is initialized iff the
network attachment is for the local node in the type system. Pare down
struct network to only the fields needed for remote network attachments
and move the local-only fields into a new struct thisNodeNetwork. Elide
the unnecessary nil-checks.

When joining a network that was previously joined but not yet reaped,
NetworkDB replaces the network struct value with a zeroed-out one with
the entries count copied over. This is also the case when joining a
network that is currently joined! Consequently, joining a network has
the side effect of clearing the broadcast queue. If the queue is cleared
while messages are still pending broadcast, convergence may be delayed
until the next bulk sync cycle.
Make it an error to join a network twice without leaving. Retain the
existing broadcast queue when rejoining a network that has not yet been

When libnetwork receives a watch event for a driver table entry from
NetworkDB it passes the event along to the interested driver. This code
contains a subtle bug: update events from NetworkDB are passed along to
the driver as Delete events! This bug was lying dormant as driver-table
entries can only be added by the driver, not updated. Now that NetworkDB
broadcasts an UpdateEvent to watchers if the entry is already known to
the local NetworkDB, irrespective of whether the event received from the
remote peer was a CREATE or UPDATE event, the bug is causing problems.
Whenever a remote node replaces an entry in the overlay_peer_table but
the intermediate delete state was not received by the local node, the
new CREATE event would be translated to an UpdateEvent by NetworkDB and
subsequently handled by the overlay driver as if the entry was deleted!
Bubble table UPDATE events up to the network driver as Update events.

When a node leaves a network or the cluster, or memberlist considers the
node as failed, NetworkDB atomically deletes all table entries (for the
left network) owned by the node. This maintains the invariant that table
entries owned by a node are present in the local database indices iff
that node is an active cluster member which is participating in the
network the entries pertain to.
(*NetworkDB).handleTableEvent() is written in a way which attempts to
minimize the amount of time it is in a critical section with the mutex
locked for writing. It first checks under a read-lock whether both the
local node and the node where the event originated are participating in
the network which the event pertains to. If the check passes, the mutex
is unlocked for reading and locked for writing so the local database
state is mutated in a critical section. That leaves a window of time
between the participation check the write-lock being acquired for a
network or node event to arrive and be processed. If a table event for a
node+network races a node or network event which triggers the purge of
all table entries for the same node+network, the invariant could be
violated. The table entry described by the table event may be reinserted
into the local database state after being purged by the node's leaving,
resulting in an orphaned table entry which the local node will bulk-sync
to other nodes indefinitely.
It's not completely wrong to perform a pre-flight check outside of the
critical section. It allows for an early return in the no-op case
without having to bear the cost of synchronization. But such optimistic
concurrency control is only sound if the condition is double-checked
inside the critical section. It is tricky to get right, and this
instance of optimistic concurrency control smells like a case of
premature optimization. Move the pre-flight check into the critical
section to ensure that the invariant is maintained.

NetworkDB's Watch() facility is problematic to use in practice. The
stream of events begins when the watch is started, so the watch cannot
be used to process table entries that existed beforehand. Either option
to process existing table entries is racy: walking the table before
starting the watch leaves a race window where events could be missed,
and walking the table after starting the watch leaves a race window
where created/updated entries could be processed twice.
Modify Watch() to initialize the channel with synthetic CREATE events
for all existing entries owned by remote nodes before hooking it up to
the live event stream. This way watchers observe an equivalent sequence
of events irrespective of whether the watch was started before or after
entries from remote nodes are added to the database. Remove the bespoke
and racy synthetic event replay logic for driver watches from the

The gossip protocol which powers NetworkDB does not guarantee in-order
reception of events. This poses a problem with deleting entries: without
some mechanism to discard stale CREATE or UPDATE events received after a
DELETE, out-of-order reception of events could result in a deleted entry
being spuriously resurrected in the local NetworkDB state! NetworkDB
handles this situation by storing "tombstone" entries for a period of
time with the Lamport timestamps of the entries' respective DELETE
events. Out-of-order CREATE or UPDATE events will be ignored by virtue
of having older timestmaps than the tombstone entry, just like how it
works for entries that have not yet been deleted.
NetworkDB was only storing a tombstone if the entry was already present
in the local database at the time of the DELETE event. If the first
event received for an entry is a DELETE, no tombstone is stored. If a
stale CREATE/UPDATE event for the entry (with an older timestamp than
the DELETE) is subsequently received, NetworkDB erroneously creates a
live entry in the local state with stale data. Modify NetworkDB to store
tombstones for DELETE events irrespective of whether the entry was known
to NetworkDB beforehand so that it correctly discards out-of-order
CREATEs and UPDATEs in all cases.

NetworkDB gossips changes to table entries to other nodes using distinct
CREATE, UPDATE and DELETE events. It is unfortunate that the wire
protocol distinguishes CREATEs from UPDATEs as nothing useful can be
done with this information. Newer events for an entry invalidate older
ones, so there is no guarantee that a CREATE event is broadcast to any
node before an UPDATE is broadcast. And due to the nature of gossip
protocols, even if the CREATE event is broadcast from the originating
node, there is no guarantee that any particular node will receive the
CREATE before an UPDATE. Any code which handles an UPDATE event
differently from a CREATE event is therefore going to behave in
unexpected ways in less than perfect conditions.
NetworkDB table watchers also receive CREATE, UPDATE and DELETE events.
Since the watched tables are local to the node, the events could all
have well-defined meanings that are actually useful. Unfortunately
NetworkDB is just bubbling up the wire-protocol event types to the
watchers. Redefine the table-watch events such that a CREATE event is
broadcast when an entry pops into existence in the local NetworkDB, an
UPDATE event is broadcast when an entry which was already present in the
NetworkDB state is modified, and a DELETE event is broadcast when an
entry which was already present in the NetworkDB state is marked for
deletion. DELETE events are broadcast with the same value as the most
recent CREATE or UPDATE event for the entry.
The handler for endpoint table events in the libnetwork agent assumed
incorrectly that CREATE events always correspond to adding a new active
endpoint and that UPDATE events always correspond to disabling an
endpoint. Fix up the handler to handle CREATE and UPDATE events using
the same code path, checking the table entry's ServiceDisabled flag to
determine which action to take.

NetworkDB uses a hierarchy of queues to prioritize messages for
broadcast. Unfortunately the logic to pull from multiple queues is
flawed. The length of the messages pulled from the first queue is not
taken into account when pulling messages from the second queue. A list
of messages up to tiwce as long as the limit could be returned! Messages
beyond the limit will be truncated unceremoniously by memberlist.
Memberlist broadcast queues assume that all messages returned from a
GetBroadcasts call will be broadcasted to other nodes in the cluster.
Messages are popped from the queue once they have hit their retransmit
limit. On a busy system messages may be broadcast fewer times than
intended, possibly even being dropped without ever being broadcast!
Subtract the length of messages pulled from the first queue from the
broadcast size limit so the limit is not exceeded when pulling from the
second queue.

NetworkDB defaults to binding to the unspecified address for gossip

The NetworkDB unit tests don't override this default, leaving them
vulnerable to flaking out as a result of rogue network traffic
perturbing the test, or the inferred advertise address not being useable
for loopback testing. And macOS prompts for permission to allow the test
executable to listen on public interfaces every time it is rebuilt.

The NetworkDB unit tests instantiate clusters which communicate over
loopback where every "node" listens on a distinct localhost port. The
tests make use of a NetworkDB configuration knob to set the port. When
the NetworkDB configuration's BindPort field is set to a nonzero value,
its memberlist instance is configured to bind to the specified port
number. However, the advertise port is left at the
memberlist.DefaultLANConfig() default value of 7946. Because of this,
nodes would be unable to contact any of the other nodes in the cluster
learned by gossip as the gossiped addresseses specify the wrong ports!
The flaky tests passed as often as they did thanks to the robustness of
the memberlist module: NetworkDB gossip and and memberlist node
liveness-probe pings to unreachable nodes can all be relayed through
the reachable nodes, the nodes on the bootstrap join list.
Make the NetworkDB unit tests less flaky by setting each node's
advertise port to the bind port.
The daemon is unaffected by this oversight as it unconditionally uses
the default listen port of 7946, which aligns with the advertise port.

From the mailing list:
Hello gophers,
We have just released Go versions 1.24.2 and 1.23.8, minor point releases.
These minor releases include 1 security fixes following the security policy:
- net/http: request smuggling through invalid chunked data
The net/http package accepted data in the chunked transfer encoding
containing an invalid chunk-size line terminated by a bare LF.
When used in conjunction with a server or proxy which incorrectly
interprets a bare LF in a chunk extension as part of the extension,
this could permit request smuggling.
The net/http package now rejects chunk-size lines containing a bare LF.
Thanks to Jeppe Bonde Weikop for reporting this issue.
This is CVE-2025-22871 and Go issue https://go.dev/issue/71988.

This is the fifth patch release in the 1.2.z series of runc. It primarily fixes
an issue caused by an upstream systemd bug.
* There was a regression in systemd v230 which made the way we define
device rule restrictions require a systemctl daemon-reload for our
transient units. This caused issues for workloads using NVIDIA GPUs.
Workaround the upstream regression by re-arranging how the unit properties
are defined.
* Dependency github.com/cyphar/filepath-securejoin is updated to v0.4.1,
to allow projects that vendor runc to bump it as well.
* CI: fixed criu-dev compilation.
* Dependency golang.org/x/net is updated to 0.33.0.

This minor release include 1 security fix following the security policy:
- crypto/elliptic: timing sidechannel for P-256 on ppc64le
Due to the usage of a variable time instruction in the assembly implementation
of an internal function, a small number of bits of secret scalars are leaked on
the ppc64le architecture. Due to the way this function is used, we do not
believe this leakage is enough to allow recovery of the private key when P-256
is used in any well known protocols.

Hello gophers,
We have just released Go versions 1.23.5 and 1.22.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- crypto/x509: usage of IPv6 zone IDs can bypass URI name constraints
A certificate with a URI which has a IPv6 address with a zone ID may
incorrectly satisfy a URI name constraint that applies to the certificate
chain.
Certificates containing URIs are not permitted in the web PKI, so this
only affects users of private PKIs which make use of URIs.
Thanks to Juho Forsén of Mattermost for reporting this issue.
This is CVE-2024-45341 and Go issue https://go.dev/issue/71156.
- net/http: sensitive headers incorrectly sent after cross-domain redirect
The HTTP client drops sensitive headers after following a cross-domain redirect.
For example, a request to a.com/ containing an Authorization header which is
redirected to b.com/ will not send that header to b.com.
In the event that the client received a subsequent same-domain redirect, however,
the sensitive headers would be restored. For example, a chain of redirects from
a.com/, to b.com/1, and finally to b.com/2 would incorrectly send the Authorization
header to b.com/2.

This is the fourth patch release of the 1.2.z release branch of runc. It
includes a fix for a regression introduced in 1.2.0 related to the
default device list.
- Re-add tun/tap devices to built-in allowed devices lists.
In runc 1.2.0 we removed these devices from the default allow-list
(which were added seemingly by accident early in Docker's history) as
a precaution in order to try to reduce the attack surface of device
inodes available to most containers. At the time we thought
that the vast majority of users using tun/tap would already be
specifying what devices they need (such as by using --device with
Docker/Podman) as opposed to doing the mknod manually, and thus
there would've been no user-visible change.
Unfortunately, it seems that this regressed a noticeable number of
users (and not all higher-level tools provide easy ways to specify
devices to allow) and so this change needed to be reverted. Users
that do not need these devices are recommended to explicitly disable
them by adding deny rules in their container configuration.

This is the third patch release of the 1.2.z release branch of runc. It
primarily fixes some minor regressions introduced in 1.2.0.
- Fixed a regression in use of securejoin.MkdirAll, where multiple
runc processes racing to create the same mountpoint in a shared rootfs
would result in spurious EEXIST errors. In particular, this regression
caused issues with BuildKit.
- Fixed a regression in eBPF support for pre-5.6 kernels after upgrading
Cilium's eBPF library version to 0.16 in runc.

Breaking changes and deprecations are included below;
Breaking changes:
Several aspects of how mount options work has been adjusted in a way that
could theoretically break users that have very strange mount option strings.
This was necessary to fix glaring issues in how mount options were being
treated. The key changes are:
- Mount options on bind-mounts that clear a mount flag are now always
applied. Previously, if a user requested a bind-mount with only clearing
options (such as rw,exec,dev) the options would be ignored and the
original bind-mount options would be set. Unfortunately this also means
that container configurations which specified only clearing mount options
will now actually get what they asked for, which could break existing
containers (though it seems unlikely that a user who requested a specific
mount option would consider it "broken" to get the mount options they
asked foruser who requested a specific mount option would consider it
"broken" to get the mount options they asked for). This also allows us to
silently add locked mount flags the user did not explicitly request to be
cleared in rootless mode, allowing for easier use of bind-mounts for
rootless containers.
- Container configurations using bind-mounts with superblock mount flags
(i.e. filesystem-specific mount flags, referred to as "data" in
mount(2), as opposed to VFS generic mount flags like MS_NODEV) will
now return an error. This is because superblock mount flags will also
affect the host mount (as the superblock is shared when bind-mounting),
which is obviously not acceptable. Previously, these flags were silently
ignored so this change simply tells users that runc cannot fulfil their
request rather than just ignoring it.
Deprecated
- runc option --criu is now ignored (with a warning), and the option will
be removed entirely in a future release. Users who need a non-standard
criu binary should rely on the standard way of looking up binaries in
$PATH.
- runc kill option -a is now deprecated. Previously, it had to be specified
to kill a container (with SIGKILL) which does not have its own private PID
namespace (so that runc would send SIGKILL to all processes). Now, this is
done automatically.
- github.com/opencontainers/runc/libcontainer/user is now deprecated, please
use github.com/moby/sys/user instead. It will be removed in a future
release.

`Parser.ParseMountRaw()` labels anonymous volumes with a `AnonymousLabel` label
(`com.docker.volume.anonymous`) label based on whether a volume has a name
(named volume) or no name (anonymous) (see [1]).
However both `VolumesService.Create()` (see [1]) and `Parser.ParseMountRaw()`
(see [2], [3]) were generating a random name for anonymous volumes. The latter
is called before `VolumesService.Create()` is called, resulting in such volumes
not being labeled as anonymous.
Generating the name was originally done in Create (fc7b904dce),
but duplicated in b3b7eb2723 with the introduction
of the new Mounts field in HostConfig. Duplicating this effort didn't have a
real effect until (`Create` would just skip generating the name), until
618f26ccbc introduced the `AnonymousLabel` in
(v24.0.0, backported to v23.0.0).
Parsing generally should not fill in defaults / generate names, so this patch;
- Removes generating volume names from `Parser.ParseMountRaw()`
- Adds a debug-log entry to `VolumesService.Create()`
- Touches up some logs to use structured logs for easier correlating logs

We had a few "runaway jobs" recently, where the job got stuck, and kept
running for 6 hours (in one case even 24 hours, probably due some github
outage). Some of those jobs could not be terminated.
While running these actions on public repositories doesn't cost us, it's
still not desirable to have jobs running for that long (as they can still
hold up the queue).
This patch adds a blanket "2 hours" time-limit to all jobs that didn't
have a limit set. We should look at tweaking those limits to actually
expected duration, but having a default at least is a start.
Also changed the position of some existing timeouts so that we have a
consistent order in which it's set; making it easier to spot locations
where no limit is defined.

The buildkit workflow uses Go to determine the version of Buildkit to run
integration-tests for. It currently uses on the default version that's
installed on the GitHub actions runners (1.21.13 currently), but this fails
if the go.mod/vendor.mod specify a higher version of Go as required version.
If this fails, the BUILDKIT_REF and REPO env-vars are not set / empty,
resulting in the workflow checking out the current (moby) repository instead
of buildkit, which fails.
This patch adds a step to explicitly install the expected version of Go.

From discussion on GitHub;
https://github.com/moby/moby/pull/46982#issuecomment-2206992611
The arm/v5 build failure looks to be due to libatomic not being included
in the link. For reasons probably buried in mailing list archives,
[gcc](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81358) and clang don't
bother to implicitly auto-link libatomic. This is not a big deal on many
modern platforms with atomic intrinsics as the compiler generates inline
instruction sequences, avoiding any libcalls into libatomic. ARMv5 is not
one of those platforms: all atomic operations require a libcall.
In theory, adding `CGO_LDFLAGS=-latomic` should fix arm/v5 builds.
While it could be argued that cgo should automatically link against
libatomic in the same way that it automatically links against libpthread,
the Go maintainers would have a valid counter-argument that it should be
the C toolchain's responsibility to link against libatomic automatically,
just like it does with libgcc or compiler-rt.

- release notes: https://github.com/containerd/containerd/releases/tag/v1.7.19
- full diff: https://github.com/containerd/containerd/compare/v1.7.18...v1.7.19
Welcome to the v1.7.19 release of containerd!
The nineteenth patch release for containerd 1.7 contains various updates and
splits the main module from the api module in preparation for the same change
in containerd 2.0. Splitting the modules will allow 1.7 and 2.x to both exist
as transitive dependencies without running into API registration errors.
Projects should use this version as the minimum 1.7 version in preparing to
use containerd 2.0 or to be imported alongside it.
Highlights
- Fix support for OTLP config
- Add API go module
- Remove overlayfs volatile option on temp mounts
- Update runc binary to v1.1.13
- Migrate platforms package to github.com/containerd/platforms
- Migrate reference/docker package to github.com/distribution/reference

These minor releases include 1 security fixes following the security policy:
net/http: denial of service due to improper 100-continue handling
The net/http HTTP/1.1 client mishandled the case where a server responds to a request with an "Expect: 100-continue" header with a non-informational (200 or higher) status. This mishandling could leave a client connection in an invalid state, where the next request sent on the connection will fail.
An attacker sending a request to a net/http/httputil.ReverseProxy proxy can exploit this mishandling to cause a denial of service by sending "Expect: 100-continue" requests which elicit a non-informational response from the backend. Each such request leaves the proxy with an invalid connection, and causes one subsequent request using that connection to fail.
Thanks to Geoff Franks for reporting this issue.

From the security announcement;
We have just released Go versions 1.22.4 and 1.21.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- archive/zip: mishandling of corrupt central directory record
The archive/zip package's handling of certain types of invalid zip files
differed from the behavior of most zip implementations. This misalignment
could be exploited to create an zip file with contents that vary depending
on the implementation reading the file. The archive/zip package now rejects
files containing these errors.
Thanks to Yufan You for reporting this issue.

- net/netip: unexpected behavior from Is methods for IPv4-mapped IPv6 addresses
The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected
for IPv4-mapped IPv6 addresses, returning false for addresses which would
return true in their traditional IPv4 forms.

We currently depend on the containerd platform-parsing to return typed
errdefs errors; the new containerd platforms module does not return such
errors, and documents that errors returned should not be used as sentinel
errors; c1438e911a/errors.go (L21-L30)
Let's type these errors ourselves, so that we don't depend on the error-types
returned by containerd, and consider that eny platform string that results in
an error is an invalid parameter.

If a node is promoted right after another node is demoted, there exists
the possibility of a race, by which the newly promoted manager attempts
to connect to the newly demoted manager for its initial Raft membership.
This connection fails, and the whole swarm Node object exits.
At this point, the daemon nodeRunner sees the exit and restarts the
Node.
However, if the address of the no-longer-manager is recorded in the
nodeRunner's config.joinAddr, the Node again attempts to connect to the
no-longer-manager, and crashes again. This repeats. The solution is to
remove the node entirely and rejoin the Swarm as a new node.
This change erases config.joinAddr from the restart of the nodeRunner,
if the node has previously become Ready. The node becoming Ready
indicates that at some point, it did successfully join the cluster, in
some fashion. If it has successfully joined the cluster, then Swarm has
its own persistent record of known manager addresses. If no joinAddr is
provided, then Swarm will choose from its persisted list of managers to
join, and will join a functioning manager.

/usr/sbin/runc is confined with "runc" profile[1] introduced in AppArmor
v4.0.0. This change breaks stopping of containers, because the profile
assigned to containers doesn't accept signals from the "runc" peer.
AppArmor >= v4.0.0 is currently part of Ubuntu Mantic (23.10) and later.
In the case of Docker, this regression is hidden by the fact that
dockerd itself sends SIGKILL to the running container after runc fails
to stop it. It is still a regression, because graceful shutdowns of
containers via "docker stop" are no longer possible, as SIGTERM from
runc is not delivered to them. This can be seen in logs from dockerd
when run with debug logging enabled and also from tracing signals with
killsnoop utility from bcc[2] (in bpfcc-tools package in Debian/Ubuntu):
Test commands:
root@cloudimg:~# docker run -d --name test redis

This change extends the docker-default profile with rules that allow
receiving signals from processes that run confined with either runc or
crun profile (crun[4] is an alternative OCI runtime that's also confined
in AppArmor >= v4.0.0, see [1]). It is backward compatible because the
peer value is a regular expression (AARE) so the referenced profile
doesn't have to exist for this profile to successfully compile and load.
Note that the runc profile has an attachment to /usr/sbin/runc. This is
the path where the runc package in Debian/Ubuntu puts the binary. When
the docker-ce package is installed from the upstream repository[3], runc
is installed as part of the containerd.io package at /usr/bin/runc.
Therefore it's still running unconfined and has no issues sending
signals to containers.

for more details.
These minor releases include 1 security fixes following the security policy:
- http2: close connections when receiving too many headers
Maintaining HPACK state requires that we parse and process all HEADERS
and CONTINUATION frames on a connection. When a request's headers exceed
MaxHeaderBytes, we don't allocate memory to store the excess headers but
we do parse them. This permits an attacker to cause an HTTP/2 endpoint
to read arbitrary amounts of header data, all associated with a request
which is going to be rejected. These headers can include Huffman-encoded
data which is significantly more expensive for the receiver to decode
than for an attacker to send.
Set a limit on the amount of excess header frames we will process before
closing a connection.

This code is currently only used in the daemon, but is also needed in other
places. We should consider moving this code to github.com/moby/sys, so that
BuildKit can also use the same implementation instead of maintaining a fork;
moving it to internal allows us to reuse this code inside the repository, but
does not allow external consumers to depend on it (which we don't want as
it's not a permanent location).
As our code only uses this in linux files, I did not add a stub for other
platforms (but we may decide to do that in the moby/sys repository).

commit c655b7dc78 added a check to make sure
the TMP_OUT variable was not set to an empty value, as such a situation would
perform an `rm -rf /**` during cleanup.
However, it was a bit too eager, because Makefile conditionals (`ifeq`) are
evaluated when parsing the Makefile, which happens _before_ the make target
is executed.
As a result `$@_TMP_OUT` was always empty when the `ifeq` was evaluated,
making it not possible to execute the `generate-files` target.
This patch changes the check to use a shell command to evaluate if the var
is set to an empty value.

In de2447c, the creation of the 'lower' file was changed from using
os.Create to using ioutils.AtomicWriteFile, which ignores the system's
umask. This means that even though the requested permission in the
source code was always 0666, it was 0644 on systems with default
umask of 0022 prior to de2447c, so the move to AtomicFile potentially
increased the file's permissions.
This is not a security issue because the parent directory does not
allow writes into the file, but it can confuse security scanners on
Linux-based systems into giving false positives.

In a container-create API request, HostConfig.NetworkMode (the identity
of the "main" network) may be a name, id or short-id.
The configuration for that network, including preferred IP address etc,
may be keyed on network name or id - it need not match the NetworkMode.
So, when migrating the old container-wide MAC address to the new
per-endpoint field - it is not safe to create a new EndpointSettings
entry unless there is no possibility that it will duplicate settings
intended for the same network (because one of the duplicates will be
discarded later, dropping the settings it contains).
This change introduces a new API restriction, if the deprecated container
wide field is used in the new API, and EndpointsConfig is provided for
any network, the NetworkMode and key under which the EndpointsConfig is
store must be the same - no mixing of ids and names.

Non-swarm networks created before network-creation-time validation
was added in 25.0.0 continued working, because the checks are not
re-run.
But, swarm creates networks when needed (with 'agent=true'), to
ensure they exist on each agent - ignoring the NetworkNameError
that says the network already existed.
By ignoring validation errors on creation of a network with
agent=true, pre-existing swarm networks with IPAM config that would
fail the new checks will continue to work too.
New swarm (overlay) networks are still validated, because they are
initially created with 'agent=false'.

Prior to release 25.0.0, the bridge in an internal network was assigned
an IP address - making the internal network accessible from the host,
giving containers on the network access to anything listening on the
bridge's address (or INADDR_ANY on the host).
This change restores that behaviour. It does not restore the default
route that was configured in the container, because packets sent outside
the internal network's subnet have always been dropped. So, a 'connect()'
to an address outside the subnet will still fail fast.

Commit e6907243af applied a fix for situations
where the client was configured with API-version negotiation, but did not yet
negotiate a version.
However, the checkVersion() function that was implemented copied the semantics
of cli.NegotiateAPIVersion, which ignored connection failures with the
assumption that connection errors would still surface further down.
However, when using the result of a failed negotiation for NewVersionError,
an API version mismatch error would be produced, masking the actual connection
error.
This patch changes the signature of checkVersion to return unexpected errors,
including failures to connect to the API.
Before this patch:
docker -H unix:///no/such/socket.sock secret ls
"secret list" requires API version 1.25, but the Docker daemon API version is 1.24

however this case is already handled by Ping itself.
Ping only returns an error when either failing to connect to the API (daemon

This test was added in 27ef09a46f, which changed
the Ping handling to ignore internal server errors. That case is tested in
TestPingFail, which verifies that we accept the Ping response if a 500
status code was received.
The TestPingWithError test was added to verify behavior if a protocol
(connection) error occurred; however the mock-client returned both a
response, and an error; the error returned would only happen if a connection
error occurred, which means that the server would not provide a reply.
Running the test also shows that returning a response is unexpected, and
ignored:
=== RUN TestPingWithError
2024/02/23 14:16:49 RoundTripper returned a response & error; ignoring response
2024/02/23 14:16:49 RoundTripper returned a response & error; ignoring response
--- PASS: TestPingWithError (0.00s)
PASS

futex: Add sys_futex_requeue()
Finish off the 'simple' futex2 syscall group by adding
sys_futex_requeue(). Unlike sys_futex_{wait,wake}() its arguments are

futex_waitv to pass the 'source' and 'destination' futexes to the

This syscall implements what was previously known as FUTEX_CMP_REQUEUE

destination.
This design explicitly allows requeueing between different types of
futex by having a different flags word per uaddr.

x86/shstk: Introduce map_shadow_stack syscall
When operating with shadow stacks enabled, the kernel will automatically
allocate shadow stacks for new threads, however in some cases userspace
will need additional shadow stacks. The main example of this is the
ucontext family of functions, which require userspace allocating and
pivoting to userspace managed stacks.
Unlike most other user memory permissions, shadow stacks need to be
provisioned with special data in order to be useful. They need to be setup
with a restore token so that userspace can pivot to them via the RSTORSSP
instruction. But, the security design of shadow stacks is that they
should not be written to except in limited circumstances. This presents a
problem for userspace, as to how userspace can provision this special
data, without allowing for the shadow stack to be generally writable.

fs: Add fchmodat2()
On the userspace side fchmodat(3) is implemented as a wrapper
function which implements the POSIX-specified interface. This
interface differs from the underlying kernel system call, which does not
have a flags argument. Most implementations require procfs [1][2].
There doesn't appear to be a good userspace workaround for this issue

The monitorDaemon() goroutine calls startContainerd() then blocks on
<-daemonWaitCh to wait for it to exit. The startContainerd() function
would (re)initialize the daemonWaitCh so a restarted containerd could be
waited on. This implementation was race-free because startContainerd()
would synchronously initialize the daemonWaitCh before returning. When
the call to start the managed containerd process was moved into the
waiter goroutine, the code to initialize the daemonWaitCh struct field
was also moved into the goroutine. This introduced a race condition.
Move the daemonWaitCh initialization to guarantee that it happens before
the startContainerd() call returns.

If a reader has caught up to the logger and is waiting for the next
message, it should stop waiting when the logger is closed. Otherwise
the reader will unnecessarily wait the full closedDrainTimeout for no
log messages to arrive.
This case was overlooked when the journald reader was recently
overhauled to be compatible with systemd 255, and the reader tests only
failed when a logical race happened to settle in such a way to exercise
the bugged code path. It was only after implicit flushing on close was
added to the journald test harness that the Follow tests would
repeatably fail due to this bug. (No new regression tests are needed.)

The journald reader test harness injects an artificial asynchronous
delay into the logging pipeline: a logged message won't be written to
the journal until at least 150ms after the Log() call returns. If a test
returns while log messages are still in flight to be written, the logs
may attempt to be written after the TempDir has been cleaned up, leading
to spurious errors.
The logger read tests which interleave writing and reading have to
include explicit synchronization points to work reliably with this delay
in place. On the other hand, tests should not be required to sync the
logger explicitly before returning. Override the Close() method in the
test harness wrapper to wait for in-flight logs to be flushed to disk.

Commit 5d5eeac310 then removed that validation step and automatically

was reverted in c59e93a67b and now the error introduced by 4f47013feb

But it turns out some users expect a network created with an IPv6

The API's EndpointConfig struct has a MacAddress field that's used for
both the configured address, and the current address (which may be generated).
A configured address must be restored when a container is restarted, but a
generated address must not.
The previous attempt to differentiate between the two, without adding a field
to the API's EndpointConfig that would show up in 'inspect' output, was a
field in the daemon's version of EndpointSettings, MACOperational. It did
not work, MACOperational was set to true when a configured address was
used. So, while it ensured addresses were regenerated, it failed to preserve
a configured address.
So, this change removes that code, and adds DesiredMacAddress to the wrapped
version of EndpointSettings, where it is persisted but does not appear in
'inspect' results. Its value is copied from MacAddress (the API field) when
a container is created.

Commit 8b7af1d0f added some code to update the DNSNames of all
endpoints attached to a sandbox by loading a new instance of each
affected endpoints from the datastore through a call to
`Network.EndpointByID()`.
This method then calls `Network.getEndpointFromStore()`, that in
turn calls `store.GetObject()`, which then calls `cache.get()`,
which calls `o.CopyTo(kvObject)`. This effectively creates a fresh
new instance of an Endpoint. However, endpoints are already kept in
memory by Sandbox, meaning we now have two in-memory instances of
the same Endpoint.
As it turns out, libnetwork is built around the idea that no two objects
representing the same thing should leave in-memory, otherwise breaking
mutex locking and optimistic locking (as both instances will have a drifting
version tracking ID -- dbIndex in libnetwork parliance).
In this specific case, this bug materializes by container rename failing
when applied a second time for a given container. An integration test is
added to make sure this won't happen again.

in 6a2542d and now the cid is always added to the list of network
aliases.
This commit reintroduces the old logic.

Commit 21e50b89c9 added a label on the buildkit
worker to advertise the host-gateway-ip. This option can be either set by the
user in the daemon config, or otherwise defaults to the gateway-ip.
If no value is set by the user, discovery of the gateway-ip happens when
initializing the network-controller (`NewDaemon`, `daemon.restore()`).
However d222bf097c changed how we handle the
daemon config. As a result, the `cli.Config` used when initializing the
builder only holds configuration information form the daemon config
(user-specified or defaults), but is not updated with information set
by `NewDaemon`.
This patch adds an accessor on the daemon to get the current daemon config.
An alternative could be to return the config by `NewDaemon` (which should
likely be a _copy_ of the config).

With containerd snapshotters enabled `docker run` currently fails when
creating a container from an image that doesn't have the default host
platform without an explicit `--platform` selection:
```
$ docker run image:amd64
Unable to find image 'asdf:amd64' locally
docker: Error response from daemon: pull access denied for asdf, repository does not exist or may require 'docker login'.
See 'docker run --help'.
```
This is confusing and the graphdriver behavior is much better here,
because it runs whatever platform the image has, but prints a warning:
```
$ docker run image:amd64
WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
```
This commits changes the containerd snapshotter behavior to be the same
as the graphdriver. This doesn't affect container creation when platform
is specified explicitly.
```
$ docker run --rm --platform linux/arm64 asdf:amd64
Unable to find image 'asdf:amd64' locally
docker: Error response from daemon: pull access denied for asdf, repository does not exist or may require 'docker login'.
See 'docker run --help'.

This matcher was only used internally in the containerd implementation of
the image store. Un-export it, and make it a local utility in that package
to prevent external use.
This package was introduced in 1616a09b61

should be no need to deprecate / alias the old location.

Commit 8ae94cafa5 added a DNS resolution
of the `device` part of the volume option.
The previous way to resolve the passed hostname was to use `addr`
option, which was handled by the same code path as the `nfs` mount type.
The issue is that `addr` is also an SMB module option handled by kernel
and passing a hostname as `addr` produces an invalid argument error.
To fix that, restore the old behavior to handle `addr` the same way as
before, and only perform the new DNS resolution of `device` if there is
no `addr` passed.

The names of extended attributes are not completely freeform. Attributes
are namespaced, and the kernel enforces (among other things) that only
attributes whose names are prefixed with a valid namespace are
permitted. The name of the attribute therefore needs to be known in
order to diagnose issues with lsetxattr. Include the name of the
extended attribute in the errors returned from the Lsetxattr and
Lgetxattr so users and us can more easily troubleshoot xattr-related
issues. Include the name in a separate rich-error field to provide code
handling the error enough information to determine whether or not the
failure can be ignored.

Since v25.0 (commit ff50388), we validate endpoint settings when
containers are created, instead of doing so when containers are started.
However, a container created prior to that release would still trigger
validation error at start-time. In such case, the API returns a 500
status code because the Go error isn't wrapped into an InvalidParameter
error. This is now fixed.

The MAC address of a running container was stored in the same place as
the configured address for a container.
When starting a stopped container, a generated address was treated as a
configured address. If that generated address (based on an IPAM-assigned
IP address) had been reused, the containers ended up with duplicate MAC
addresses.
So, remember whether the MAC address was explicitly configured, and
clear it if not.
