If a perf event doesn't fit into remaining buffer space return NULL to
remap buf and fetch the event again.
Keep the logic to error out on inadequate input from fuzzing.

SPE doesn't have this set even though synthetic memory data is generated

Commit 3f6634d997db ("iommu: Use right way to retrieve iommu_ops") started
triggering a NULL pointer dereference for some omap variants:
__iommu_probe_device from probe_iommu_group+0x2c/0x38
probe_iommu_group from bus_for_each_dev+0x74/0xbc

bus_set_iommu from omap_iommu_init+0x88/0xcc
omap_iommu_init from do_one_initcall+0x44/0x24
This is caused by omap iommu probe returning 0 instead of ERR_PTR(-ENODEV)
as noted by Jason Gunthorpe <jgg@ziepe.ca>.
Looks like the regression already happened with an earlier commit

In get_initial_state, it calls notify_initial_state_done(skb,..) if
cb->args[5]==1. If genlmsg_put() failed in notify_initial_state_done(),
the skb will be freed by nlmsg_free(skb).
Then get_initial_state will goto out and the freed skb will be used by
return value skb->len, which is a uaf bug.
What's worse, the same problem goes even further: skb can also be
freed in the notify_*_state_change -> notify_*_state calls below.
Thus 4 additional uaf bugs happened.
My patch lets the problem callee functions: notify_initial_state_done
and notify_*_state_change return an error code if errors happen.
So that the error codes could be propagated and the uaf bugs can be avoid.

bpf_tcp_gen_syncookie looks at the IP version in the IP header and
validates the address family of the socket. It supports IPv4 packets in
AF_INET6 dual-stack sockets.
On the other hand, bpf_tcp_check_syncookie looks only at the address
family of the socket, ignoring the real IP version in headers, and
validates only the packet size. This implementation has some drawbacks:
1. Packets are not validated properly, allowing a BPF program to trick
bpf_tcp_check_syncookie into handling an IPv6 packet on an IPv4
socket.
2. Dual-stack sockets fail the checks on IPv4 packets. IPv4 clients end
up receiving a SYNACK with the cookie, but the following ACK gets
dropped.
This patch fixes these issues by changing the checks in
bpf_tcp_check_syncookie to match the ones in bpf_tcp_gen_syncookie. IP
version from the header is taken into account, and it is validated
properly with address family.

In some cases, xdp tx_queue can get used before initialization.
1. interface up/down
2. ring buffer size change
When CPU cores are lower than maximum number of channels of sfc driver,
it creates new channels only for XDP.
When an interface is up or ring buffer size is changed, all channels
are initialized.
But xdp channels are always initialized later.
So, the below scenario is possible.
Packets are received to rx queue of normal channels and it is acted
XDP_TX and tx_queue of xdp channels get used.
But these tx_queues are not initialized yet.
If so, TX DMA or queue error occurs.
In order to avoid this problem.
1. initializes xdp tx_queues earlier than other rx_queue in
efx_start_channels().
2. checks whether tx_queue is initialized or not in efx_xdp_tx_buffers().
Splat looks like:

While parsing user-provided actions, openvswitch module may dynamically
allocate memory and store pointers in the internal copy of the actions.
So this memory has to be freed while destroying the actions.
Currently there are only two such actions: ct() and set(). However,
there are many actions that can hold nested lists of actions and
ovs_nla_free_flow_actions() just jumps over them leaking the memory.
For example, removal of the flow with the following actions will lead
to a leak of the memory allocated by nf_ct_tmpl_alloc():
actions:clone(ct(commit),0)
Non-freed set() action may also leak the 'dst' structure for the
tunnel info including device references.
Under certain conditions with a high rate of flow rotation that may
cause significant memory leak problem (2MB per second in reporter's
case). The problem is also hard to mitigate, because the user doesn't
have direct control over the datapath flows generated by OVS.
Fix that by iterating over all the nested actions and freeing
everything that needs to be freed recursively.
New build time assertion should protect us from this problem if new
actions will be added in the future.
Unfortunately, openvswitch module doesn't use NLA_F_NESTED, so all
attributes has to be explicitly checked. sample() and clone() actions
are mixing extra attributes into the user-provided action list. That
prevents some code generalization too.

'OVS_CLONE_ATTR_EXEC' is an internal attribute that is used for
performance optimization inside the kernel. It's added by the kernel
while parsing user-provided actions and should not be sent during the
flow dump as it's not part of the uAPI.
The issue doesn't cause any significant problems to the ovs-vswitchd
process, because reported actions are not really used in the
application lifecycle and only supposed to be shown to a human via
ovs-dpctl flow dump. However, the action list is still incorrect
and causes the following error if the user wants to look at the
datapath flows:
# ovs-dpctl add-dp system@ovs-system
# ovs-dpctl add-flow "<flow match>" "clone(ct(commit),0)"

<flow match>, packets:0, bytes:0, used:never,

Disable check for queue being enabled in ice_vc_dis_qs_msg, because
there could be a case when queues were created, but were not enabled.
We still need to delete those queues.
Normal workflow for VF looks like:
Enable path:
VIRTCHNL_OP_ADD_ETH_ADDR (opcode 10)
VIRTCHNL_OP_CONFIG_VSI_QUEUES (opcode 6)
VIRTCHNL_OP_ENABLE_QUEUES (opcode 8)
Disable path:
VIRTCHNL_OP_DISABLE_QUEUES (opcode 9)
VIRTCHNL_OP_DEL_ETH_ADDR (opcode 11)
The issue appears only in stress conditions when VF is enabled and
disabled very fast.
Eventually there will be a case, when queues are created by
VIRTCHNL_OP_CONFIG_VSI_QUEUES, but are not enabled by
VIRTCHNL_OP_ENABLE_QUEUES.
In turn, these queues are not deleted by VIRTCHNL_OP_DISABLE_QUEUES,
because there is a check whether queues are enabled in
ice_vc_dis_qs_msg.
When we bring up the VF again, we will see the "Failed to set LAN Tx queue
context" error during VIRTCHNL_OP_CONFIG_VSI_QUEUES step. This
happens because old 16 queues were not deleted and VF requests to create
16 more, but ice_sched_get_free_qparent in ice_ena_vsi_txq would fail to
find a parent node for first newly requested queue (because all nodes
are allocated to 16 old queues).
Testing Hints:
Just enable and disable VF fast enough, so it would be disabled before
reaching VIRTCHNL_OP_ENABLE_QUEUES.

VIRTCHNL_OP_DISABLE_QUEUES stage will fail with error:
[ 639.531454] disable queue 89 failed 14
[ 639.532233] Failed to disable LAN Tx queues, error: ICE_ERR_AQ_ERROR
[ 639.533107] ice 0000:02:00.0: Failed to stop Tx ring 0 on VSI 5
The reason for the fail is that we are trying to send AQ command to
delete queue 89, which has never been created and receive an "invalid
argument" error from firmware.
As this queue has never been created, it's teid and ring->txq_teid
have default value 0.
ice_dis_vsi_txq has a check against non-existent queues:
node = ice_sched_find_node_by_teid(pi->root, q_teids[i]);
if (!node)
continue;
But on some platforms the Root Node of Tx scheduler has a teid = 0.
Hence, ice_sched_find_node_by_teid finds a node with teid = 0 (it is
pi->root), and we go further to submit an erroneous request to firmware.

Arm64 systems rely on store_cpu_topology() to call update_siblings_masks()
to transfer the toplogy to the various cpu masks. This needs to be done
before the call to notify_cpu_starting() which tells the scheduler about
each cpu found, otherwise the core scheduling data structures are setup
in a way that does not match the actual topology.
With smt_mask not setup correctly we bail on `cpumask_weight(smt_mask) == 1`
for !leaders in:
notify_cpu_starting()
cpuhp_invoke_callback_range()
sched_cpu_starting()
sched_core_cpu_starting()
which leads to rq->core not being correctly set for !leader-rq's.
Without this change stress-ng (which enables core scheduling in its prctl
tests in newer versions -- i.e. with PR_SCHED_CORE support) causes a warning
and then a crash (trimmed for legibility):

Prior to commit eeef2f6b9f6e ("net: stmmac: Start adding phylink support"),
the check for a valid max_speed setting was to check if it was greater
than zero. This commit got it right, but subsequent patches just checked
for non-zero, which is incorrect for DT platforms.
In commit 92c3807b9ac3 ("net: stmmac: convert to phylink_get_linkmodes()")
the conversion switched completely to checking for non-zero value as a

VSI is set as default forwarding one when promisc mode is set for
PF interface, when PF is switched to switchdev mode or when VF
driver asks to enable allmulticast or promisc mode for the VF
interface (when vf-true-promisc-support priv flag is off).
The third case is buggy because in that case VSI associated with
VF remains as default one after VF removal.
Reproducer:
1. Create VF
echo 1 > sys/class/net/ens7f0/device/sriov_numvfs
2. Enable allmulticast or promisc mode on VF
ip link set ens7f0v0 allmulticast on
ip link set ens7f0v0 promisc on
3. Delete VF
echo 0 > sys/class/net/ens7f0/device/sriov_numvfs
4. Try to enable promisc mode on PF
ip link set ens7f0 promisc on
Although it looks that promisc mode on PF is enabled the opposite
is true because ice_vsi_sync_fltr() responsible for IFF_PROMISC
handling first checks if any other VSI is set as default forwarding
one and if so the function does not do anything. At this point
it is not possible to enable promisc mode on PF without re-probe
device.
To resolve the issue this patch clear default forwarding VSI
during ice_vsi_release() when the VSI to be released is the default
one.

Fix a use-after-free when using page_pool with page fragments. We
encountered this problem during normal RX in the hns3 driver:
(1) Initially we have three descriptors in the RX queue. The first one
allocates PAGE1 through page_pool, and the other two allocate one
half of PAGE2 each. Page references look like this:
RX_BD1 _______ PAGE1
RX_BD2 _______ PAGE2
RX_BD3 _________/
(2) Handle RX on the first descriptor. Allocate SKB1, eventually added
to the receive queue by tcp_queue_rcv().
(3) Handle RX on the second descriptor. Allocate SKB2 and pass it to
netif_receive_skb():
netif_receive_skb(SKB2)
ip_rcv(SKB2)
SKB3 = skb_clone(SKB2)
SKB2 and SKB3 share a reference to PAGE2 through
skb_shinfo()->dataref. The other ref to PAGE2 is still held by
RX_BD3:
SKB2 ---+- PAGE2
SKB3 __/ /
RX_BD3 _________/
(3b) Now while handling TCP, coalesce SKB3 with SKB1:
tcp_v4_rcv(SKB3)
tcp_try_coalesce(to=SKB1, from=SKB3) // succeeds
kfree_skb_partial(SKB3)
skb_release_data(SKB3) // drops one dataref
SKB1 _____ PAGE1
\____
SKB2 _____ PAGE2
/
RX_BD3 _________/
In skb_try_coalesce(), __skb_frag_ref() takes a page reference to
PAGE2, where it should instead have increased the page_pool frag
reference, pp_frag_count. Without coalescing, when releasing both
SKB2 and SKB3, a single reference to PAGE2 would be dropped. Now
when releasing SKB1 and SKB2, two references to PAGE2 will be
dropped, resulting in underflow.
(3c) Drop SKB2:
af_packet_rcv(SKB2)
consume_skb(SKB2)
skb_release_data(SKB2) // drops second dataref
page_pool_return_skb_page(PAGE2) // drops one pp_frag_count
SKB1 _____ PAGE1
\____
PAGE2
/
RX_BD3 _________/
(4) Userspace calls recvmsg()
Copies SKB1 and releases it. Since SKB3 was coalesced with SKB1, we
release the SKB3 page as well:
tcp_eat_recv_skb(SKB1)
skb_release_data(SKB1)
page_pool_return_skb_page(PAGE1)
page_pool_return_skb_page(PAGE2) // drops second pp_frag_count
(5) PAGE2 is freed, but the third RX descriptor was still using it!
In our case this causes IOMMU faults, but it would silently corrupt
memory if the IOMMU was disabled.
Change the logic that checks whether pp_recycle SKBs can be coalesced.
We still reject differing pp_recycle between 'from' and 'to' SKBs, but
in order to avoid the situation described above, we also reject
coalescing when both 'from' and 'to' are pp_recycled and 'from' is
cloned.
The new logic allows coalescing a cloned pp_recycle SKB into a page
refcounted one, because in this case the release (4) will drop the right
reference, the one taken by skb_try_coalesce().

("vrf: add mac header for tunneled packets when sniffer is attached")
an Ethernet header was cooked for traffic originating from tunnel devices.
However, the header is added based on whether the mac_header is unset
and ignores cases where the device doesn't expose a mac header to upper
layers, such as in ip tunnels like ipip and gre.
Traffic originating from such devices still appears garbled when capturing
on the vrf device.
Fix by observing whether the original device exposes a header to upper
layers, similar to the logic done in af_packet.
In addition, skb->mac_len needs to be adjusted after adding the Ethernet
header for the skb_push/pull() surrounding dev_queue_xmit_nit() to work
on these packets.
