The fix for tcp-fast-open ensures that the connect permission is being
mediated correctly but it didn't add an artifact to the feature set to
advertise the fix is available. Add an artifact so that the test suite
can identify if the fix has not been properly applied or a new
unexpected regression has occurred.

sendmsg()/sendto() with MSG_FASTOPEN is a combination of connect(2) and
write(2): it opens the connection in the SYN. apparmor_socket_sendmsg()
only checks AA_MAY_SEND, so a profile that grants send but denies connect
lets a confined task open an outbound TCP/MPTCP connection that connect(2)
would have refused, bypassing connect mediation.
Mediate the implicit connect when MSG_FASTOPEN is set and a destination
is supplied. Add it to apparmor_socket_sendmsg() (not the shared
aa_sock_msg_perm() helper, which recvmsg also uses) and call aa_sk_perm()
directly, mirroring the selinux and tomoyo fixes. sk_is_tcp() does not
cover MPTCP fast open, so the SOCK_STREAM/IPPROTO_MPTCP arm is explicit.

Pull IMA updates from Mimi Zohar: - Introduce IMA and EVM post-quantum ML-DSA signature support ML-DSA signature support for IMA and EVM is limited to sigv3 signatures, which calculates and verifies a hash of a compact structure containing the file data/metadata hash, hash type, and hash algorithm. IMA and EVM still calculate the file data/metadata hashes respectively. - Introduce support for removing IMA measurement list records stored in kernel memory The IMA measurement list can grow large depending on policy, but removing records breaks remote attestation, unless they are safely preserved and made available for attestation requests. Until environments are prepared to preserve the measurement records, a new CONFIG_IMA_STAGING Kconfig option is introduced to guard against deletion. Several approaches for removing measurement list records were evaluated but rejected due to filesystem constraints, the introduction of a new critical data record, and locking concerns. Two methods are being upstreamed: staged deletion with confirmation, and staged deletion of N records without confirmation. Both methods minimize the period during which new measurements are blocked from being appended to the measurement list by staging the measurement list. A comparison of the two methods is included in the documentation. - Some code cleanup, and a couple of bug fixes * tag 'integrity-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: doc: security: Add documentation of exporting and deleting IMA measurements ima: Support staging and deleting N measurements records ima: Add support for flushing the hash table when staging measurements ima: Add support for staging measurements with prompt ima: Introduce ima_dump_measurement() ima: Use snprintf() in create_securityfs_measurement_lists ima: Mediate open/release method of the measurements list ima: Introduce _ima_measurements_start() and _ima_measurements_next() ima: Introduce per binary measurements list type binary_runtime_size value ima: Introduce per binary measurements list type ima_num_records counter ima: Replace static htable queue with dynamically allocated array ima: Remove ima_h_table structure evm: terminate and bound the evm_xattrs read buffer integrity: Add support for sigv3 verification using ML-DSA keys integrity: Refactor asymmetric_verify for reusability integrity: Check that algo parameter is within valid range integrity: Check for NULL returned by asymmetric_key_public_key ima: return error early if file xattr cannot be changed ima: Fix sigv3 signature handling for EVM_IMA_XATTR_DIGSIG
Pull selinux updates from Paul Moore:
"A number of SELinux patches, almost all of which are either minor
fixes or hardening patches:
- Additional verifications when loading new SELinux policy
Multiple patches by Christian Göttsche to add additional
validations to the code responsible for loading and parsing SELinux
policy as it is loaded into the kernel.
- Avoid nontransitive comparisons comparisons in our sorting code
Done to prevent unexpected sorting results due to overflow. Qualys
documented a similar issue with glibc
https://www.qualys.com/2024/01/30/qsort.txt
- Consistently use u16 for SELinux security classes
- Move from page allocations to kmalloc() based allocations
Unfortunately one of these patches had to be reverted, but you
should see a fixed version during the next merge window.
- Move from kmalloc_objs() to kzalloc_objs() in the policy load code
- Reorder sel_kill_sb() slightly to match other pseudo filesystems
- Simplify things with QSTR() instead of QSTR_INIT()
- Minor comment typo fixes"

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Work on removing rtnl_lock protection throughout the stack
continues. In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even
tho user space wants a dump of all netdevs, most of the time, the
OOO programming model results in repeating the dump for each
netdev. Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on
retransmit timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 >
40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot
express reqid changes or migrate Transport mode selectors.
The new interface identifies the SA via SPI and mark, supports
reqid changes, address family changes, encap removal, and uses an
atomic create+install flow under x->lock to prevent SN/IV reuse
during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff:
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto
API users, since it changed crypto transformation objects into
reference-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the
global crypto API as obsolete and insecure.
Wireless:
- Major rework of station bandwidth handling, fixing issues with
lower capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter:
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions:
- Remove TLS + sockmap integration. TLS wants to pin user pages to
avoid a copy, and sockmap wants to write to the input stream. More
work on this integration is clearly needed, and we can't find any
users (original author admitted that they never deployed it).
- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from the
vendor that added this are AWOL.
- Remove more ATM code, trying to leave behind only what PPPoATM
needs, AAL5 and br2684 with permanent circuits.
- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.
- Disable 32-bit x_tables compatibility (32bit binaries on 64bit
kernel) interface in user namespaces. To be deleted completely,
soon.
- Remove 5/10 MHz support from cfg80211/mac80211.
