 "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"

====================
ENA driver bug fixes

From: David Arinzon <darinzon@amazon.com>

This patchset contains multiple bug fixes for the
ENA driver.
====================

Link: https://lore.kernel.org/r/20240410091358.16289-1-darinzon@amazon.comSigned-off-by: Paolo Abeni <pabeni@redhat.com>

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

						for u in gc_inflight_list:
						  if (total_refs == inflight_refs)
						    add u to gc_candidates

						// gc_candidates={L, V}

						for u in gc_candidates:
						  scan_children(u, dec_inflight)

						// embryo (skb1) was not
						// reachable from L yet, so V's
						// inflight remains unchanged
__skb_queue_tail(L, skb1)
unix_state_unlock(L)
						for u in gc_candidates:
						  if (u.inflight)
						    scan_children(u, inc_inflight_move_tail)

						// V count=1 inflight=2 (!)

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.
