The prandom_u32() function has been a deprecated inline wrapper around
get_random_u32() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. The same also applies to get_random_int(), which is
just a wrapper around get_random_u32(). This was done as a basic find
and replace.

Support direct writes to nf_conn:mark from TC and XDP prog types. This
is useful when applications want to store per-connection metadata. This
is also particularly useful for applications that run both bpf and
iptables/nftables because the latter can trivially access this metadata.
One example use case would be if a bpf prog is responsible for advanced
packet classification and iptables/nftables is later used for routing
due to pre-existing/legacy code.

====================
The following set contains changes for your *net-next* tree:
- make conntrack ignore packets that are delayed (containing
data already acked). The current behaviour to flag them as INVALID
causes more harm than good, let them pass so peer can send an
immediate ACK for the most recent sequence number.
- make conntrack recognize when both peers have sent 'invalid' FINs:
This helps cleaning out stale connections faster for those cases where
conntrack is no longer in sync with the actual connection state.
- Now that DECNET is gone, we don't need to reserve space for DECNET
related information.
- compact common 'find a free port number for the new inbound
connection' code and move it to a helper, then cap number of tries
the new helper will make until it gives up.
- replace various instances of strlcpy with strscpy, from Wolfram Sang.

__nf_ct_try_assign_helper() remains in place but it now requires a
template to configure the helper.
A toggle to disable automatic helper assignment was added by:
a900689264 ("netfilter: nf_ct_helper: allow to disable automatic helper assignment")
in 2012 to address the issues described in "Secure use of iptables and
connection tracking helpers". Automatic conntrack helper assignment was
disabled by:
3bb398d925 ("netfilter: nf_ct_helper: disable automatic helper assignment")
back in 2016.
This patch removes the sysctl and modparam toggles, users now have to
rely on explicit conntrack helper configuration via ruleset.

check that auto-assignment does not happen anymore.

To clear the flow table on flow table free, the following sequence
normally happens in order:
1) gc_step work is stopped to disable any further stats/del requests.
2) All flow table entries are set to teardown state.
3) Run gc_step which will queue HW del work for each flow table entry.
4) Waiting for the above del work to finish (flush).
5) Run gc_step again, deleting all entries from the flow table.
6) Flow table is freed.
But if a flow table entry already has pending HW stats or HW add work
step 3 will not queue HW del work (it will be skipped), step 4 will wait
for the pending add/stats to finish, and step 5 will queue HW del work
which might execute after freeing of the flow table.
To fix the above, this patch flushes the pending work, then it sets the
teardown flag to all flows in the flowtable and it forces a garbage
collector run to queue work to remove the flows from hardware, then it
flushes this new pending work and (finally) it forces another garbage
collector run to remove the entry from the software flowtable.

Instead of parsing the data and then validate that type and length are
correct, pass a description of the expected data so it can be validated
upfront before parsing it to bail out earlier.
This patch adds a new .size field to specify the maximum size of the
data area. The .len field is optional and it is used as an input/output
field, it provides the specific length of the expected data in the input
path. If then .len field is not specified, then obtained length from the
netlink attribute is stored. This is required by cmp, bitwise, range and
immediate, which provide no netlink attribute that describes the data
length. The immediate expression uses the destination register type to
infer the expected data type.
Relying on opencoded validation of the expected data might lead to
subtle bugs as described in 7e6bc1f6ca ("netfilter: nf_tables:
stricter validation of element data").
Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
Update template to validate variable length extensions. This patch adds
a new .ext_len[id] field to the template to store the expected extension
length. This is used to sanity check the initialization of the variable
length extension.
Use PTR_ERR() in nft_set_elem_init() to report errors since, after this
update, there are two reason why this might fail, either because of
ENOMEM or insufficient room in the extension field (EINVAL).
Kernels up until 7e6bc1f6ca ("netfilter: nf_tables: stricter
validation of element data") allowed to copy more data to the extension
than was allocated. This ext_len field allows to validate if the
destination has the correct size as additional check.

Introduce bpf_ct_set_status and bpf_ct_change_status kfunc helpers in
order to set nf_conn field of allocated entry or update nf_conn status

share the permitted status field changes between netlink and BPF side

It is required to introduce two kfuncs taking nf_conn___init and nf_conn

checking. This would disallow passing nf_conn___init to kfunc taking
nf_conn, and vice versa. We cannot remove the KF_TRUSTED_ARGS flag as we

order to change nf_conn timeout. This is same as ctnetlink_change_timeout,
hence code is shared between both by extracting it out to

Apart from this, bpf_ct_set_timeout is only called for newly allocated

sensitive to order of setting status and timeout after allocation.

Introduce bpf_nf_ct_tuple_parse utility routine to consolidate common

We extract out a helper __nf_ct_set_timeout, used by the ctnetlink and
nf_conntrack_bpf code, extract it out to nf_conntrack_core, so that
nf_conntrack_bpf doesn't need a dependency on CONFIG_NF_CT_NETLINK.
Later this helper will be reused as a helper to set timeout of allocated
but not yet inserted CT entry.
The allocation functions return struct nf_conn___init instead of
nf_conn, to distinguish allocated CT from an already inserted or looked
up CT. This is later used to enforce restrictions on what kfuncs
allocated CT can be used with.
