The gtp generic netlink family sends notifications on its "gtp"
multicast group when a PDP context is added or deleted, and for GTP-U
echo responses. They carry the same attributes as a GETPDP reply: the
MS and peer addresses, and the TEIDs, or the TID and the flow label.
GETPDP requires CAP_NET_ADMIN, but generic netlink lets any user join a
multicast group by default, so an unprivileged user in the network
namespace of the gtp device can read all of this. Found by code
inspection.
Fix by marking the group with GENL_MCAST_CAP_NET_ADMIN, like the psample
"packets" group, and with uns-admin-perm in the gtp netlink spec. Only
users with CAP_NET_ADMIN in the user namespace owning the network
namespace can then join it.
This is still weaker than the check on GETPDP, which needs
CAP_NET_ADMIN in the initial user namespace: in a network namespace
owned by another user namespace, its root can join the group, but not
use GETPDP. Genetlink has no multicast group flag for the initial user
namespace, and ioam6 pairs its ops and its group the same way. This fix
blocks the unprivileged users.
Tested by joining the group as root, as root without CAP_NET_ADMIN, and
as an unprivileged user:
Before:
root: joined
root without CAP_NET_ADMIN: joined
nobody: joined
After:
root: joined
root without CAP_NET_ADMIN: EPERM
nobody: EPERM

Jeff Layton extended the netlink listener-set operation so that a
management daemon can register NFSD's programs with rpcbind itself.
This prevents an unresponsive rpcbind from stalling NFSD adminis-
tration for a minute at a time.
Bulk delegation recall now adjusts the number of delegations it
wants returned, based on memory pressure. The previous mechanism
was spec-conformant, but it requested all delegations to be
returned at once. Clients are free to return few or none in such
cases, but requesting smaller batches of delegations is more
neighborly.
In preparation for handling TLS KeyUpdate, the server's TCP receive
path has been reworked to handle control records. In the process,
the use of sock_recvmsg was replaced with ->read_sock, which contends
less with other holders of the socket lock.
NFSv2 XDR code is now generated by xdrgen, which mechanically
generates the encoders and decoders from the RPC language
specification for the protocol. Replacing hand-built XDR code
makes prototyping new protocol elements faster, reduces errors, and
improves memory safety. Replacement of XDR code for newer NFS
versions will continue in subsequent releases of NFSD.
The remaining bulk of changes in v7.4 is bug fixes, clean-ups, and
small optimizations. Sincere thanks to all contributors, reviewers,
testers, and bug reporters who participated in the v7.4 NFSD
development cycle.

Ethernet network interfaces may have more than one front-facing port.
The phy_port infrastructure was introduced to keep track of

capability of these ports. Add a ethnl netlink message to report this

The GTP (GPRS Tunnelling Protocol, user plane) generic netlink family
has no YAML specification under Documentation/netlink/specs/, so it
cannot be consumed by the ynl tooling used for user-space clients,
documentation and selftests.
Add a genetlink-legacy spec describing the existing family: the PDP
context management commands (NEWPDP, DELPDP, GETPDP) and the GTP-U echo
request (ECHOREQ), the GTPA_* attribute set, and the "gtp" multicast
group. Command and attribute values are taken from
include/uapi/linux/gtp.h and match it one-to-one. The request
attributes of each command are the ones its handler in
drivers/net/gtp.c reads, and the reply attributes the ones
gtp_genl_fill_info() emits.
The notifications sent on the "gtp" group are not described: they reuse
the command values of the NEWPDP, DELPDP and ECHOREQ requests, which
the ynl code generator cannot express with the existing uapi header.
The family doc says so.
Add the matching CFLAGS_gtp entry to tools/net/ynl/Makefile.deps, so
the generated code is built against the tree's gtp.h instead of an
older one installed on the host.
This only adds the description; there is no kernel code or uapi change.

Previously, neigh_managed_work() was not rescheduled within
1s since commit ed6cd6a178 ("net, neigh: Set lower cap for
neigh_managed_work rearming").
Later, commit 211da42eaa ("net, neigh: introduce
interval_probe_time_ms for periodic probe") added
INTERVAL_PROBE_TIME_MS and changed the limit to 1ms.
The limit actually did not work but was fixed with
netlink_range_validation by commit 6d79b223ec ("neighbour:
Enforce min/max to NDTPA_INTERVAL_PROBE_TIME_MS.").
neigh_table is now per-netns, and a user could hog CPU by setting
INTERVAL_PROBE_TIME_MS to a small value.
Let's floor the value at 1 second.
This is a user-visible change, but given we had the 1s floor before
and the default is 5s, it is unlikely that anyone but syzbot is
setting it below 1s and affected by this change.

Replace binary opts in lwtunnel-ip and lwtunnel-ip6 with a nested
lwtunnel-ip-opts set. Add attribute sets for geneve, vxlan, and erspan
IP options to match linux/lwtunnel.h.
Note the kernel encodes LWTUNNEL_IP_OPTS_GENEVE differently for requests
vs dumps. On the request path, the kernel iterates and reads one
CLASS/TYPE/DATA triplet per geneve option. On the dump path, the kernel
opens only one nested geneve option and writes a CLASS/TYPE/DATA triplet
for every option within it. Before there is a proper way to handle it,
I will just omit geneve options and use binary for it.

YNL enum ifla-inet6-stats got misaligned with C, as two commits
reordered the enum.
In commit b4a11b2033 ("net: fix IPSTATS_MIB_OUTPKGS increment in
OutForwDatagrams."), IPSTATS_MIB_OUTPKTS was renamed to _OUTREQUESTS
and a new _OUTPKTS was as the last entry.
In commit 652e2c7778 ("net: reorganize IP MIB values (II)"), the
IPSTATS_MIB_* enum was reorganized for data locality.
Neither of these commits updated the YNL spec.
This changed uAPI, as IPSTATS_MIB_* is used as indicies in an u64 array,
exported as IFLA_INET6_STATS by inet6_fill_ifla6_stats_attrs().
This patch updates ifla-inet6-stats to reflect both of these commits.
Next time we want to reorganize these counters we should properly apply
mapping as to maintain the current order on the netlink side.
While touching these entries, also remove the dash from ect{0,1}-pkts,
so that they align with the C naming.
This pre-existing issue was identified by Sashiko during review of
commit 2b0aecb7b2 ("netlink: specs: rt-link: add accept-ra-min-lft").

Conntrack flush supports filtering by zone using CTA_ZONE, but this
attribute is really hard to use from user space applications. The
reason is that it is not possible to tell if it's supported or not.
Older kernels silently ignore CTA_ZONE. And in that case they just
happily flush all the entries from all zones breaking all the existing
connections. So, applications have to infer support from the kernel
version. While it works in most cases, it's not a particularly
reliable or desired way to check kernel capabilities from applications
that aim to be portable. There should be a better way to probe or
discover features in the kernel.
The CTA_FILTER interface on the other hand is simple enough to probe.
We can check for NLM_F_DUMP_FILTERED in the dump to see if filtering
is supported. And unknown sub-attributes in CTA_FILTER are rejected
explicitly since strict validation is in use there.
Let's add new CTA_FILTER_ZONE that signals that CTA_ZONE should be
filtered on. It is a flag, since everything in the CTA_FILTER is a
bit mask, i.e., a form of a flag. If set, it means that CTA_ZONE must
be present and be used for filtering. If the flag is not set however,
the filtering on CTA_ZONE will still take place to ensure backwards
compatibility. So, the flag doesn't really change the filtering
behavior, but it allows user space applications to properly discover
support for CTA_ZONE filtering without need to rely on kernel version
parsing or risk accidental flushes of the entire conntrack table,
and also without modifying the kernel state.
A new test variant is added to test with and without the new flag.
Since the setup code is moved into a shared function, expectations
replaced with assertions to bail early if the base setup fails to
avoid the cascade of secondary failures that can be misleading.
Error return is only for the SKIP cases.

port-index is the only way rate-set can address a leaf (port) rate object,
but it was never listed in the request, so the generated policy has no
entry for it. The op declares .maxattr = DEVLINK_ATTR_PARENT_DEV, so the
attribute still reaches info->attrs[], validated against a zeroed slot -
NLA_UNSPEC, length 0 - which GENL_DONT_VALIDATE_STRICT accepts at any
length.
devlink_port_get_from_attrs() then runs nla_get_u32() on it. Handed a
zero-length port-index the kernel reads the four bytes past the payload,
which are the next attribute's header, and acts on the port index those
spell out. Since we're reading a linear skb the OOB read is still
within the same memory allocation, it's just garbage. We also do not
echo the garbage back to the user so it's not an info leak either.
Hence not treating this is a real bug fix.
rate-new is left alone on purpose. It creates rate nodes, resolved by
name through devlink_rate_node_get_from_attrs(), and never looks at
port-index.

We are missing the pad attribute in a number of subsets.
Worse, dl-attr-stats which is a separate attr space doesn't
define pad, but reuses the value from the root attr set
(DEVLINK_ATTR_PAD). This would break parsing stats on
an arch without CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS.

devlink_nl_rate_parent_fill() emits DEVLINK_ATTR_PARENT_DEV via
devlink_nl_put_nested_handle(), which adds DEVLINK_ATTR_NETNS_ID
whenever the parent rate node lives on a devlink instance in another
netns. Now that we defined dl-nested-devlink subset, which unlike
dl-parent-dev includes netns-id, let's switch to it. The rate APIs
input genuinely does not accept the netns-id, so we need to subset
them to stick with dl-parent-dev.

- devlink_nl_region_snapshots_id_put() emits one
DEVLINK_ATTR_REGION_SNAPSHOT sub-nest per entry on the region's

- devlink_nl_linecard_fill() emits one DEVLINK_ATTR_LINECARD_TYPE per

we haven't taken the time to properly define the sub-sets for

We need this subsetting because within the DEVLINK_ATTR_PORT_FUNCTION

The "# TODO: fill in the attributes in between" gap before selftests
(176) hides exactly one attribute, DEVLINK_ATTR_NESTED_DEVLINK (175).
devlink_nl_fill() calls devlink_nl_nested_fill() unconditionally, which
emits one of these per entry in devlink->nested_rels (mlx5, ice).
Unlike the other TODO gaps this is a single attribute of an already
modelled type, so just fill it in.

AFAICT this is a cosmetic change - both DEVLINK_RELOAD_LIMIT_UNSPEC

don't declare them as supported. User will see either a policy

ctrl_policy_family[] accepts CTRL_ATTR_FAMILY_ID and ctrl_getfamily()
looks the family up by it, but the spec lists only family-name in the
request. C YNL generates struct members and setters from that list, so
struct nlctrl_getfamily_req has no way to carry an id and resolving a
family id - the one a client gets handed in nlmsg_type - back to a name
needs a full dump.
Python YNL happens to encode any attribute of the op's attribute set,
which is why this went unnoticed.

mask and pad are declared the wrong way round, giving mask 11 and
pad 12, while enum netlink_policy_type_attr has
NL_POLICY_TYPE_ATTR_PAD at 11 and NL_POLICY_TYPE_ATTR_MASK at 12.
The kernel emits the mask for every NLA_POLICY_MASK() attribute, so a
Python YNL client parsing a policy dump maps it onto pad and throws it
away - 30 of them in ethtool's policy alone. In the other direction the
64-bit alignment padding, which the kernel does emit on architectures
without efficient unaligned access, is decoded as a u64 mask and blows
up the whole dump. But those architectures are rare.
The generated C parser is not affected, it keys the attributes off the
uAPI symbol names rather than off the values the spec derives.

Minor touch ups to the XSK-related doc strings in the netdev spec.
Tx checksum is (obviously?) Layer 4 (TCP/UDP), not Layer 3 (IP).
The xdp_zc_max_segs change is more subtle, I guess, but to kernel devs
saying "frags" may sound like the number of skb frags. The value includes
the head in this case. The default of 1 means single buffer, XDP_USE_SG
sockets are refused when it is 1. Let's use the word "buffer" instead
of "frag".

Currently netlink-raw.yaml contains two if keys and two then keys in a
single mapping that enforces a "len" for "pad" members and a "len" or
"struct" for binary members.
During validation PyYAML resolves duplicate keys last-wins, so only the
binary rule survives. Pad has not been validated since commit
bf08f32c8c ("tools/net/ynl: Add support for nested structs") added
the second if/then pair in January 2024.
None of the current specs violate this rule, but this validation should
not be parser dependent and unspecified. Strict YAML validators such as
Red Hat's VS Code YAML extension and Adrien Verge's yamllint will
reject the netlink-raw.yaml schema:
Command:
$ yamllint Documentation/netlink/netlink-raw.yaml
Output:
185:13 error duplication of key "if" in mapping (key-duplicates)
189:13 error duplication of key "then" in mapping (key-duplicates)

Paolo pointed out an issue flagged at low priority by Sashiko -
we're currently not handling BE{16,32} attributes in policy dumps.
Commit 3f4285d741 ("netlink: specs: fou: local-v4 and peer-v4 are big
endian") flipped two fou attributes from NLA_U32 to NLA_BE32.
This made them vanish from the policy dump.
Follow the YAML spec format and treat byte order as a property of
a u16 / u32 rather than a type of its own. I don't have a strong
preference either way. The YNL format "feels cleaner" but the
kernel's separate type is easier when handling decoding.
I don't think that the policy type is actually usable for decoding
(since it only contains input types) so I went with YNL and added
the separate attr.
A missing byte order means host order, again like in the YAML specs.

All four RTT attributes tell the reader to left-shift, which inflates the
value by 16 to 64 times, and the two usec ones say the result is in msecs.
The attributes carry srtt_us and mdev_us, which hold 3 and 2 fractional
bits. The shift to get the integer part would be a right shift.
Drop the instructions instead of turning them around. The number of
fractional bits is the part worth documenting, whether to shift, divide or
convert to a double is up to the caller.

TCP_FASTOPEN_COOKIE_MAX is the longest cookie we accept, not the shortest
one. Cookies are even sized, from 4 bytes up, and the ones Linux itself
generates are 8 bytes, so a 16 byte minimum declares all but the longest
cookie invalid. The reference policy kept under #if 0 in tcp_metrics.c
spells it as a maximum, which is what .len means for NLA_BINARY.
The IPv6 addresses err the other way. The policy uses
NLA_POLICY_EXACT_LEN() for both, so a request carrying a longer address is
rejected with -ERANGE, even though the spec advertises 16 bytes as a mere
minimum. Were the policy generated from this spec, as kernel-policy: global
promises, the check would turn into NLA_POLICY_MIN_LEN() and start
accepting over-long addresses, of which nla_get_in6_addr() would take the
first 16 bytes.
Nothing generated changes. fopen-cookie is reply-only so it never gets a
policy entry, and exact-len only feeds the policy (and the fixed size array
form, which needs a sub-type).
