Notable user impacting bugs
- On multi device filesystems, recovery was looping in
btree_trans_too_many_iters(). This checks if a transaction has touched
too many btree paths (because of iteration over many keys), and isuses
a restart to drop unneeded paths. But it's now possible for some paths
to exceed the previous limit without iteration in the interior btree
update path, since the transaction commit will do alloc updates for
every old and new btree node, and during journal replay we don't use
the btree write buffer for locking reasons and thus those updates use
btree paths when they wouldn't normally.
- Fix a corner case in rebalance when moving extents on a durability=0
device. This wouldn't be hit when a device was formatted with
durability=0 since in that case we'll only use it as a write through
cache (only cached extents will live on it), but durability can now be
changed on an existing device.
- bch2_get_acl() could rarely forget to handle a transaction restart;
this manifested as the occasional missing acl that came back after
dropping caches.
- Fix a major performance regression on high iops multithreaded write
workloads (only since 6.9-rc1); a previous fix for a deadlock in the
interior btree update path to check the journal watermark introduced a
dependency on the state of btree write buffer flushing that we didn't
want.
- Assorted other repair paths and recovery fixes.

This patch adds a new helper chk_msk_info() to show the counters in
mptcp_info of the given info, and check that the timestamps move
forward. Use it to show newly added last_data_sent, last_data_recv
and last_ack_recv in mptcp_info in chk_last_time_info().

This patch adds "last time" fields last_data_sent, last_data_recv and
last_ack_recv in struct mptcp_sock to record the last time data_sent,
data_recv and ack_recv happened. They all are initialized as
tcp_jiffies32 in __mptcp_init_sock(), and updated as tcp_jiffies32 too
when data is sent in __subflow_push_pending(), data is received in
__mptcp_move_skbs_from_subflow(), and ack is received in ack_update_msk().
Similar to tcpi_last_data_sent, tcpi_last_data_recv and tcpi_last_ack_recv
exposed with TCP, this patch exposes the last time "an action happened" for
MPTCP in mptcp_info, named mptcpi_last_data_sent, mptcpi_last_data_recv and
mptcpi_last_ack_recv, calculated in mptcp_diag_fill_info() as the time
deltas between now and the newly added last time fields in mptcp_sock.
Since msk->last_ack_recv needs to be protected by mptcp_data_lock/unlock,
and lock_sock_fast can sleep and be quite slow, move the entire
mptcp_data_lock/unlock block after the lock/unlock_sock_fast block.
Then mptcpi_last_data_sent and mptcpi_last_data_recv are set in
lock/unlock_sock_fast block, while mptcpi_last_ack_recv is set in
mptcp_data_lock/unlock block, which is protected by a spinlock and
should not block for too long.
Also add three reserved bytes in struct mptcp_info not to have holes in
this structure exposed to userspace.

====================
mana: Add flex array to struct mana_cfg_rx_steer_req_v2 (part)
The "struct mana_cfg_rx_steer_req_v2" uses a dynamically sized set of
trailing elements. Specifically, it uses a "mana_handle_t" array. So,
use the preferred way in the kernel declaring a flexible array [1].
At the same time, prepare for the coming implementation by GCC and Clang
of the __counted_by attribute. Flexible array members annotated with
__counted_by can have their accesses bounds-checked at run-time via
CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for
strcpy/memcpy-family functions).
Also, avoid the open-coded arithmetic in the memory allocator functions
[2] using the "struct_size" macro.
Moreover, use the "offsetof" helper to get the indirect table offset
instead of the "sizeof" operator and avoid the open-coded arithmetic in
pointers using the new flex member. This new structure member also allow
us to remove the "req_indir_tab" variable since it is no longer needed.
Now, it is also possible to use the "flex_array_size" helper to compute
the size of these trailing elements in the "memcpy" function.
Specifically, the first commit adds the flex member and the patches 2 and
3 refactor the consumers of the "struct mana_cfg_rx_steer_req_v2".

This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1][2].
As the "req" variable is a pointer to "struct mana_cfg_rx_steer_req_v2"
and this structure ends in a flexible array:
struct mana_cfg_rx_steer_req_v2 {
[...]
mana_handle_t indir_tab[] __counted_by(num_indir_entries);

the preferred way in the kernel is to use the struct_size() helper to

The patch mentioned in the `Fixes` tag removed the explicit assignment
of tx_info->xdpf to NULL with the justification that there's no need
to set tx_info->xdpf to NULL and tx_info->num_of_bufs to 0 in case
of a mapping error. Both values won't be used once the mapping function
returns an error, and their values would be overridden by the next
transmitted packet.
While both values do indeed get overridden in the next transmission
call, the value of tx_info->xdpf is also used to check whether a TX
descriptor's transmission has been completed (i.e. a completion for it
was polled).
An example scenario:
1. Mapping failed, tx_info->xdpf wasn't set to NULL
2. A VF reset occurred leading to IO resource destruction and
a call to ena_free_tx_bufs() function
3. Although the descriptor whose mapping failed was freed by the
transmission function, it still passes the check
if (!tx_info->skb)
(skb and xdp_frame are in a union)
4. The xdp_frame associated with the descriptor is freed twice
This patch returns the assignment of NULL to tx_info->xdpf to make the
cleaning function knows that the descriptor is already freed.

ENA has two types of TX queues:
- queues which only process TX packets arriving from the network stack
- queues which only process TX packets forwarded to it by XDP_REDIRECT
or XDP_TX instructions
The ena_free_tx_bufs() cycles through all descriptors in a TX queue
and unmaps + frees every descriptor that hasn't been acknowledged yet
by the device (uncompleted TX transactions).
The function assumes that the processed TX queue is necessarily from
the first category listed above and ends up using napi_consume_skb()
for descriptors belonging to an XDP specific queue.
This patch solves a bug in which, in case of a VF reset, the
descriptors aren't freed correctly, leading to crashes.

Missing IO completions check is called every second (HZ jiffies).
This commit fixes several issues with this check:
1. Duplicate queues check:
Max of 4 queues are scanned on each check due to monitor budget.
Once reaching the budget, this check exits under the assumption that
the next check will continue to scan the remainder of the queues,
but in practice, next check will first scan the last already scanned
queue which is not necessary and may cause the full queue scan to
last a couple of seconds longer.
The fix is to start every check with the next queue to scan.
For example, on 8 IO queues:
Bug: [0,1,2,3], [3,4,5,6], [6,7]
Fix: [0,1,2,3], [4,5,6,7]
2. Unbalanced queues check:
In case the number of active IO queues is not a multiple of budget,
there will be checks which don't utilize the full budget
because the full scan exits when reaching the last queue id.
The fix is to run every TX completion check with exact queue budget
regardless of the queue id.
For example, on 7 IO queues:
Bug: [0,1,2,3], [4,5,6], [0,1,2,3]
Fix: [0,1,2,3], [4,5,6,0], [1,2,3,4]
The budget may be lowered in case the number of IO queues is less
than the budget (4) to make sure there are no duplicate queues on
the same check.
For example, on 3 IO queues:
Bug: [0,1,2,0], [1,2,0,1]
Fix: [0,1,2], [0,1,2]

Small unsigned types are promoted to larger signed types in
the case of multiplication, the result of which may overflow.
In case the result of such a multiplication has its MSB
turned on, it will be sign extended with '1's.
This changes the multiplication result.
Code example of the phenomenon:
-------------------------------
u16 x, y;
size_t z1, z2;
x = y = 0xffff;
printk("x=%x y=%x\n",x,y);
z1 = x*y;
z2 = (size_t)x*y;
printk("z1=%lx z2=%lx\n", z1, z2);
Output:
-------
x=ffff y=ffff
z1=fffffffffffe0001 z2=fffe0001
The expected result of ffff*ffff is fffe0001, and without the
explicit casting to avoid the unwanted sign extension we got
fffffffffffe0001.
This commit adds an explicit casting to avoid the sign extension
issue.

Garbage collector does not take into account the risk of embryo getting
enqueued during the garbage collection. If such embryo has a peer that
carries SCM_RIGHTS, two consecutive passes of scan_children() may see a
different set of children. Leading to an incorrectly elevated inflight
count, and then a dangling pointer within the gc_inflight_list.
sockets are AF_UNIX/SOCK_STREAM
S is an unconnected socket
L is a listening in-flight socket bound to addr, not in fdtable
V's fd will be passed via sendmsg(), gets inflight count bumped
connect(S, addr) sendmsg(S, [V]); close(V) __unix_gc()
---------------- ------------------------- -----------
NS = unix_create1()
skb1 = sock_wmalloc(NS)
L = unix_find_other(addr)
unix_state_lock(L)
unix_peer(S) = NS
// V count=1 inflight=0
NS = unix_peer(S)
skb2 = sock_alloc()
skb_queue_tail(NS, skb2[V])
// V became in-flight
// V count=2 inflight=1
close(V)
// V count=1 inflight=1
// GC candidate condition met

If there is a GC-candidate listening socket, lock/unlock its state. This
makes GC wait until the end of any ongoing connect() to that socket. After
flipping the lock, a possibly SCM-laden embryo is already enqueued. And if
there is another embryo coming, it can not possibly carry SCM_RIGHTS. At
this point, unix_inflight() can not happen because unix_gc_lock is already
taken. Inflight graph remains unaffected.

In Clause 5 of IEEE Std 802-2014, two sublayers of the data link layer
(DLL) of the Open Systems Interconnection basic reference model (OSI/RM)
are described; the medium access control (MAC) and logical link control
(LLC) sublayers. The MAC sublayer is the one facing the physical layer.
In 8.2 of IEEE Std 802.1Q-2022, the Bridge architecture is described. A
Bridge component comprises a MAC Relay Entity for interconnecting the Ports
of the Bridge, at least two Ports, and higher layer entities with at least
a Spanning Tree Protocol Entity included.
Each Bridge Port also functions as an end station and shall provide the MAC
Service to an LLC Entity. Each instance of the MAC Service is provided to a
distinct LLC Entity that supports protocol identification, multiplexing,
and demultiplexing, for protocol data unit (PDU) transmission and reception
by one or more higher layer entities.
It is described in 8.13.9 of IEEE Std 802.1Q-2022 that in a Bridge, the LLC
Entity associated with each Bridge Port is modeled as being directly
connected to the attached Local Area Network (LAN).
On the switch with CPU port architecture, CPU port functions as Management
Port, and the Management Port functionality is provided by software which
functions as an end station. Software is connected to an IEEE 802 LAN that
is wholly contained within the system that incorporates the Bridge.
Software provides access to the LLC Entity associated with each Bridge Port
by the value of the source port field on the special tag on the frame
received by software.
We call frames that carry control information to determine the active
topology and current extent of each Virtual Local Area Network (VLAN),
i.e., spanning tree or Shortest Path Bridging (SPB) and Multiple VLAN
Registration Protocol Data Units (MVRPDUs), and frames from other link
constrained protocols, such as Extensible Authentication Protocol over LAN
(EAPOL) and Link Layer Discovery Protocol (LLDP), link-local frames. They
are not forwarded by a Bridge. Permanently configured entries in the
filtering database (FDB) ensure that such frames are discarded by the
Forwarding Process. In 8.6.3 of IEEE Std 802.1Q-2022, this is described in
detail:
Each of the reserved MAC addresses specified in Table 8-1
(01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]) shall be
permanently configured in the FDB in C-VLAN components and ERs.
Each of the reserved MAC addresses specified in Table 8-2
(01-80-C2-00-00-[01,02,03,04,05,06,07,08,09,0A,0E]) shall be permanently
configured in the FDB in S-VLAN components.
Each of the reserved MAC addresses specified in Table 8-3
(01-80-C2-00-00-[01,02,04,0E]) shall be permanently configured in the FDB
in TPMR components.
The FDB entries for reserved MAC addresses shall specify filtering for all
Bridge Ports and all VIDs. Management shall not provide the capability to
modify or remove entries for reserved MAC addresses.
The addresses in Table 8-1, Table 8-2, and Table 8-3 determine the scope of
propagation of PDUs within a Bridged Network, as follows:
The Nearest Bridge group address (01-80-C2-00-00-0E) is an address that
no conformant Two-Port MAC Relay (TPMR) component, Service VLAN (S-VLAN)
component, Customer VLAN (C-VLAN) component, or MAC Bridge can forward.
PDUs transmitted using this destination address, or any other addresses
that appear in Table 8-1, Table 8-2, and Table 8-3
(01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]), can
therefore travel no further than those stations that can be reached via a
single individual LAN from the originating station.
The Nearest non-TPMR Bridge group address (01-80-C2-00-00-03), is an
address that no conformant S-VLAN component, C-VLAN component, or MAC
Bridge can forward; however, this address is relayed by a TPMR component.
PDUs using this destination address, or any of the other addresses that
appear in both Table 8-1 and Table 8-2 but not in Table 8-3
(01-80-C2-00-00-[00,03,05,06,07,08,09,0A,0B,0C,0D,0F]), will be relayed
by any TPMRs but will propagate no further than the nearest S-VLAN
component, C-VLAN component, or MAC Bridge.
The Nearest Customer Bridge group address (01-80-C2-00-00-00) is an
address that no conformant C-VLAN component, MAC Bridge can forward;
however, it is relayed by TPMR components and S-VLAN components. PDUs
using this destination address, or any of the other addresses that appear
in Table 8-1 but not in either Table 8-2 or Table 8-3
(01-80-C2-00-00-[00,0B,0C,0D,0F]), will be relayed by TPMR components and
S-VLAN components but will propagate no further than the nearest C-VLAN
component or MAC Bridge.
Because the LLC Entity associated with each Bridge Port is provided via CPU
port, we must not filter these frames but forward them to CPU port.
In a Bridge, the transmission Port is majorly decided by ingress and egress
rules, FDB, and spanning tree Port State functions of the Forwarding
Process. For link-local frames, only CPU port should be designated as
destination port in the FDB, and the other functions of the Forwarding
Process must not interfere with the decision of the transmission Port. We
call this process trapping frames to CPU port.
Therefore, on the switch with CPU port architecture, link-local frames must
be trapped to CPU port, and certain link-local frames received by a Port of
a Bridge comprising a TPMR component or an S-VLAN component must be
excluded from it.
A Bridge of the switch with CPU port architecture cannot comprise a
Two-Port MAC Relay (TPMR) component as a TPMR component supports only a
subset of the functionality of a MAC Bridge. A Bridge comprising two Ports
(Management Port doesn't count) of this architecture will either function
as a standard MAC Bridge or a standard VLAN Bridge.
Therefore, a Bridge of this architecture can only comprise S-VLAN
components, C-VLAN components, or MAC Bridge components. Since there's no
TPMR component, we don't need to relay PDUs using the destination addresses
specified on the Nearest non-TPMR section, and the proportion of the
Nearest Customer Bridge section where they must be relayed by TPMR
components.
One option to trap link-local frames to CPU port is to add static FDB
entries with CPU port designated as destination port. However, because that
Independent VLAN Learning (IVL) is being used on every VID, each entry only
applies to a single VLAN Identifier (VID). For a Bridge comprising a MAC
Bridge component or a C-VLAN component, there would have to be 16 times
4096 entries. This switch intellectual property can only hold a maximum of
2048 entries. Using this option, there also isn't a mechanism to prevent
link-local frames from being discarded when the spanning tree Port State of
the reception Port is discarding.
The remaining option is to utilise the BPC, RGAC1, RGAC2, RGAC3, and RGAC4
registers. Whilst this applies to every VID, it doesn't contain all of the
reserved MAC addresses without affecting the remaining Standard Group MAC
Addresses. The REV_UN frame tag utilised using the RGAC4 register covers
the remaining 01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F] destination
addresses. It also includes the 01-80-C2-00-00-22 to 01-80-C2-00-00-FF
destination addresses which may be relayed by MAC Bridges or VLAN Bridges.
The latter option provides better but not complete conformance.
This switch intellectual property also does not provide a mechanism to trap
link-local frames with specific destination addresses to CPU port by
Bridge, to conform to the filtering rules for the distinct Bridge
components.
Therefore, regardless of the type of the Bridge component, link-local
frames with these destination addresses will be trapped to CPU port:
01-80-C2-00-00-[00,01,02,03,0E]
In a Bridge comprising a MAC Bridge component or a C-VLAN component:
Link-local frames with these destination addresses won't be trapped to
CPU port which won't conform to IEEE Std 802.1Q-2022:
01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F]
In a Bridge comprising an S-VLAN component:
Link-local frames with these destination addresses will be trapped to CPU
port which won't conform to IEEE Std 802.1Q-2022:
01-80-C2-00-00-00
Link-local frames with these destination addresses won't be trapped to
CPU port which won't conform to IEEE Std 802.1Q-2022:
01-80-C2-00-00-[04,05,06,07,08,09,0A]
Currently on this switch intellectual property, if the spanning tree Port
State of the reception Port is discarding, link-local frames will be
discarded.
To trap link-local frames regardless of the spanning tree Port State, make
the switch regard them as Bridge Protocol Data Units (BPDUs). This switch
intellectual property only lets the frames regarded as BPDUs bypass the
spanning tree Port State function of the Forwarding Process.
With this change, the only remaining interference is the ingress rules.
When the reception Port has no PVID assigned on software, VLAN-untagged
frames won't be allowed in. There doesn't seem to be a mechanism on the
switch intellectual property to have link-local frames bypass this function
of the Forwarding Process.

managing MSIX for the aux device (for RoCE). The existing
scheme statically carves out the MSIX vectors for RoCE even if
the RoCE driver is not loaded. The new scheme adds flexibility
and allows the L2 driver to use the RoCE MSIX vectors if needed
when they are unused by the RoCE driver. The last patch updates

The existing scheme sets aside a number of MSIX/NQs for the RoCE

is not flexible and limits the resources available for the L2 rings
if RoCE is never used.
Modify the scheme so that the RoCE MSIX/NQs can be used by the L2
driver if they are not used for RoCE. The MSIX/NQs are now
represented by 3 fields. bp->ulp_num_msix_want contains the
desired default value, edev->ulp_num_msix_vec contains the
available value (but not necessarily in use), and
ulp_tbl->msix_requested contains the actual value in use by RoCE.
The L2 driver can dip into edev->ulp_num_msix_vec if necessary.
We need to add rtnl_lock() back in bnxt_register_dev() and
bnxt_unregister_dev() to synchronize the MSIX usage between L2 and
RoCE.

adds the aux device into the aux bus subsytem. Refactor the logic into
separate functions, first function to initialize the aux device along
with the required resources and second, to actually add the device to
the aux bus subsytem.
This separation helps to create bnxt_en_dev much earlier and save its
resources separately.

struct mlx5_pkt_reformat contains a naked union of a u32 id and a
dr_action pointer which is used when the action is SW-managed (when
pkt_reformat.owner is set to MLX5_FLOW_RESOURCE_OWNER_SW). Using id
directly in that case is incorrect, as it maps to the least significant
32 bits of the 64-bit pointer in mlx5_fs_dr_action and not to the pkt
reformat id allocated in firmware.
For the purpose of comparing whether two rules are identical,
interpreting the least significant 32 bits of the mlx5_fs_dr_action
pointer as an id mostly works... until it breaks horribly and produces
the outcome described in [1].
This patch fixes mlx5_flow_dests_cmp to correctly compare ids using
mlx5_fs_dr_action_get_pkt_reformat_id for the SW-managed rules.

Previously, add_rule_fg would only add newly created rules from the
handle into the tree when they had a refcount of 1. On the other hand,
create_flow_handle tries hard to find and reference already existing
identical rules instead of creating new ones.
These two behaviors can result in a situation where create_flow_handle
1) creates a new rule and references it, then
2) in a subsequent step during the same handle creation references it
again,
resulting in a rule with a refcount of 2 that is not linked into the
tree, will have a NULL parent and root and will result in a crash when
the flow group is deleted because del_sw_hw_rule, invoked on rule
deletion, assumes node->parent is != NULL.
This happened in the wild, due to another bug related to incorrect
handling of duplicate pkt_reformat ids, which lead to the code in
create_flow_handle incorrectly referencing a just-added rule in the same
flow handle, resulting in the problem described above. Full details are
at [1].
This patch changes add_rule_fg to add new rules without parents into
the tree, properly initializing them and avoiding the crash. This makes
it more consistent with how rules are added to an FTE in
create_flow_handle.

Next patch will move devlink register to be first. Therefore, whenever
mlx5 will register a param, the user will be notified.
In order to notify the user, devlink is using the get() callback of
the param. Hence, resources that are being used by the get() callback
must be set before the devlink param is registered.
Therefore, store eswitch pointer inside mdev before registering the
param.

- kprobes: Fix possible use-after-free issue on kprobe registration. Since
check_kprobe_address_safe() uses `is_module_text_address()` and
`__module_text_address()` separately, if the probe address is on an
unloading module, the first `is_module_text_address()` return true but
the second `__module_text_address()` returns NULL (module is unloaded
between them). Thus it expects the probe is on the kernel text, and
skips to get the module reference. In this case, when it arms a breakpoint
on the probe address, it may cause a use-after-free problem.
To fix this issue, we only use `__module_text_address()` once and tries
to get reference of the module, if it fails, reject the probe.

After commit 40867d74c3 ("net: Add l3mdev index to flow struct and
avoid oif reset for port devices") it is possible to configure FIB rules
that match on iif / oif being a l3mdev port. It was not possible before
as these parameters were reset to the ifindex of the l3mdev device
itself prior to the FIB rules lookup.
Add tests that cover this functionality as it does not seem to be
covered by existing ones and I am aware of at least one user that needs
this functionality in addition to the one mentioned in [1].
Reuse the existing FIB rules tests by simply configuring a VRF prior to
the test and removing it afterwards. Differentiate the output of the
non-VRF tests from the VRF tests by appending "(VRF)" to the test name
if a l3mdev FIB rule is present.
Verified that these tests do fail on kernel 5.15.y which does not
include the previously mentioned commit:
