Dinghao Liu 4d8cc87d18 scsi: be2iscsi: Fix a memleak in beiscsi_init_wrb_handle()
[ Upstream commit 235f2b548d7f4ac5931d834f05d3f7f5166a2e72 ]

When an error occurs in the for loop of beiscsi_init_wrb_handle(), we
should free phwi_ctxt->be_wrbq before returning an error code to prevent
potential memleak.

Petr Pavlu bc5b79df6d tracing: Fix a warning when allocating buffered events fails
[ Upstream commit 34209fe83ef8404353f91ab4ea4035dbc9922d04 ]

Function trace_buffered_event_disable() produces an unexpected warning
when the previous call to trace_buffered_event_enable() fails to
allocate pages for buffered events.

The situation can occur as follows:

* The counter trace_buffered_event_ref is at 0.

* The soft mode gets enabled for some event and
  trace_buffered_event_enable() is called. The function increments
  trace_buffered_event_ref to 1 and starts allocating event pages.

* The allocation fails for some page and trace_buffered_event_disable()
  is called for cleanup.

* Function trace_buffered_event_disable() decrements
  trace_buffered_event_ref back to 0, recognizes that it was the last
  use of buffered events and frees all allocated pages.

* The control goes back to trace_buffered_event_enable() which returns.
  The caller of trace_buffered_event_enable() has no information that
  the function actually failed.

* Some time later, the soft mode is disabled for the same event.
  Function trace_buffered_event_disable() is called. It warns on
  "WARN_ON_ONCE(!trace_buffered_event_ref)" and returns.

Buffered events are just an optimization and can handle failures. Make
trace_buffered_event_enable() exit on the first failure and left any
cleanup later to when trace_buffered_event_disable() is called.

Nathan Rossi 22143a0e5a arm64: dts: imx8mp: imx8mq: Add parkmode-disable-ss-quirk on DWC3
[ Upstream commit 209043cf092d7b0d4739921b3f11d6d0b451eabf ]

The i.MX8MP and i.MX8MQ devices both use the same DWC3 controller and
are both affected by a known issue with the controller due to specific
behaviour when park mode is enabled in SuperSpeed host mode operation.

Under heavy USB traffic from multiple endpoints the controller will
sometimes incorrectly process transactions such that some transactions
are lost, or the controller may hang when processing transactions. When
the controller hangs it does not recover.

This issue is documented partially within the linux-imx vendor kernel
which references a Synopsys STAR number 9001415732 in commits [1] and
additional details in [2]. Those commits provide some additional
controller internal implementation specifics around the incorrect
behaviour of the SuperSpeed host controller operation when park mode is
enabled.

The summary of this issue is that the host controller can incorrectly
enter/exit park mode such that part of the controller is in a state
which behaves as if in park mode even though it is not. In this state
the controller incorrectly calculates the number of TRBs available which
results in incorrect access of the internal caches causing the overwrite
of pending requests in the cache which should have been processed but
are ignored. This can cause the controller to drop the requests or hang
waiting for the pending state of the dropped requests.

The workaround for this issue is to disable park mode for SuperSpeed
operation of the controller through the GUCTL1[17] bit. This is already
available as a quirk for the DWC3 controller and can be enabled via the
'snps,parkmode-disable-ss-quirk' device tree property.

It is possible to replicate this failure on an i.MX8MP EVK with a USB
Hub connecting 4 SuperSpeed USB flash drives. Performing continuous
small read operations (dd if=/dev/sd... of=/dev/null bs=16) on the block
devices will result in device errors initially and will eventually
result in the controller hanging.

The VA addresses are coming from rdma-core in this diagram can be
arbitrary, but for 64k pages, the VA may be offset by some number of HCA
4k pages and followed by some number of HCA 4k pages.

The current iterator doesn't account for either the preceding 4k pages or
the following 4k pages.

Fix the issue by extending the ib_block_iter to contain the number of DMA
pages like comment [1] says and by using __sg_advance to start the
iterator at the first live HCA page.

The changes are contained in a parallel set of iterator start and next
functions that are umem aware and specific to umem since there is one user
of the rdma_for_each_block() without umem.

These two fixes prevents the extra pages before and after the user MR
data.

Fix the preceding pages by using the __sq_advance field to start at the
first 4k page containing MR data.

Fix the following pages by saving the number of pgsz blocks in the
iterator state and downcounting on each next.

This fix allows for the elimination of the small page crutch noted in the
Fixes.

[ Upstream commit 1fefca6c57fb928d2131ff365270cbf863d89c88 ]

The ACPI specification says:

"If an error occurs while obtaining the meter reading or if the value
is not available then an Integer with all bits set is returned"

Since the "integer" is 32 bits in case of the ACPI power meter,
userspace will get a power reading of 2^32 * 1000 miliwatts (~4.29 MW)
in case of such an error. This was discovered due to a lm_sensors
bugreport (https://github.com/lm-sensors/lm-sensors/issues/460).

Shifeng Li 19269741c3 RDMA/irdma: Fix UAF in irdma_sc_ccq_get_cqe_info()
[ Upstream commit 2b78832f50c4d711e161b166d7d8790968051546 ]

When removing the irdma driver or unplugging its aux device, the ccq
queue is released before destorying the cqp_cmpl_wq queue.
But in the window, there may still be completion events for wqes. That
will cause a UAF in irdma_sc_ccq_get_cqe_info().

Md Haris Iqbal 233c32bcf0 RDMA/rtrs-srv: Destroy path files after making sure no IOs in-flight
[ Upstream commit c4d32e77fc1006f99eeb78417efc3d81a384072a ]

Destroying path files may lead to the freeing of rdma_stats. This creates
the following race.

An IO is in-flight, or has just passed the session state check in
process_read/process_write. The close_work gets triggered and the function
rtrs_srv_close_work() starts and does destroy path which frees the
rdma_stats. After this the function process_read/process_write resumes and
tries to update the stats through the function rtrs_srv_update_rdma_stats

This commit solves the problem by moving the destroy path function to a
later point. This point makes sure any inflights are completed. This is
done by qp drain, and waiting for all in-flights through ops_id.

While processing info request, it could so happen that the srv_path goes
to CLOSING state, cause of any of the error events from RDMA. That state
change should be picked up while trying to change the state in

call in process_info_req fails, we fail the processing.

We should also check the return value for rtrs_srv_path_up, since it
sends a link event to the client above, and the client can fail for any
reason.

[ Upstream commit 7269cba53d906cf257c139d3b3a53ad272176bca ]

Currently supplicant dependent optee device enumeration only registers
devices whenever tee-supplicant is invoked for the first time. But it
forgets to remove devices when tee-supplicant daemon stops running and
closes its context gracefully. This leads to following error for fTPM
driver during reboot/shutdown:

[   73.466791] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024

Fix this by adding an attribute for supplicant dependent devices so that
the user-space service can detect and detach supplicant devices before
closing the supplicant:

$ for dev in /sys/bus/tee/devices/*; do if [[ -f "$dev/need_supplicant" && -f "$dev/driver/unbind" ]]; \
      then echo $(basename "$dev") > $dev/driver/unbind; fi done

Ido Schimmel b5ca945612 drop_monitor: Require 'CAP_SYS_ADMIN' when joining "events" group
[ Upstream commit e03781879a0d524ce3126678d50a80484a513c4b ]

The "NET_DM" generic netlink family notifies drop locations over the
"events" multicast group. This is problematic since by default generic
netlink allows non-root users to listen to these notifications.

Fix by adding a new field to the generic netlink multicast group
structure that when set prevents non-root users or root without the
'CAP_SYS_ADMIN' capability (in the user namespace owning the network
namespace) from joining the group. Set this field for the "events"
group. Use 'CAP_SYS_ADMIN' rather than 'CAP_NET_ADMIN' because of the
nature of the information that is shared over this group.

Note that the capability check in this case will always be performed
against the initial user namespace since the family is not netns aware
and only operates in the initial network namespace.

A new field is added to the structure rather than using the "flags"
field because the existing field uses uAPI flags and it is inappropriate
to add a new uAPI flag for an internal kernel check. In net-next we can
rework the "flags" field to use internal flags and fold the new field
into it. But for now, in order to reduce the amount of changes, add a
new field.

Since the information can only be consumed by root, mark the control
plane operations that start and stop the tracing as root-only using the
'GENL_ADMIN_PERM' flag.

Tested using [1].

Ido Schimmel 07c8229c02 psample: Require 'CAP_NET_ADMIN' when joining "packets" group
[ Upstream commit 44ec98ea5ea9cfecd31a5c4cc124703cb5442832 ]

The "psample" generic netlink family notifies sampled packets over the
"packets" multicast group. This is problematic since by default generic
netlink allows non-root users to listen to these notifications.

Fix by marking the group with the 'GENL_UNS_ADMIN_PERM' flag. This will
prevent non-root users or root without the 'CAP_NET_ADMIN' capability
(in the user namespace owning the network namespace) from joining the
group.

Tested using [1].

Before:

 # capsh -- -c ./psample_repo
 # capsh --drop=cap_net_admin -- -c ./psample_repo

After:

 # capsh -- -c ./psample_repo
 # capsh --drop=cap_net_admin -- -c ./psample_repo

Eric Dumazet 008b807fe4 tcp: do not accept ACK of bytes we never sent
[ Upstream commit 3d501dd326fb1c73f1b8206d4c6e1d7b15c07e27 ]

This patch is based on a detailed report and ideas from Yepeng Pan
and Christian Rossow.

ACK seq validation is currently following RFC 5961 5.2 guidelines:

   The ACK value is considered acceptable only if
   it is in the range of ((SND.UNA - MAX.SND.WND) <= SEG.ACK <=
   SND.NXT).  All incoming segments whose ACK value doesn't satisfy the
   above condition MUST be discarded and an ACK sent back.  It needs to
   be noted that RFC 793 on page 72 (fifth check) says: "If the ACK is a
   duplicate (SEG.ACK < SND.UNA), it can be ignored.  If the ACK
   acknowledges something not yet sent (SEG.ACK > SND.NXT) then send an
   ACK, drop the segment, and return".  The "ignored" above implies that
   the processing of the incoming data segment continues, which means
   the ACK value is treated as acceptable.  This mitigation makes the
   ACK check more stringent since any ACK < SND.UNA wouldn't be
   accepted, instead only ACKs that are in the range ((SND.UNA -
   MAX.SND.WND) <= SEG.ACK <= SND.NXT) get through.

This can be refined for new (and possibly spoofed) flows,
by not accepting ACK for bytes that were never sent.

This greatly improves TCP security at a little cost.

I added a Fixes: tag to make sure this patch will reach stable trees,
even if the 'blamed' patch was adhering to the RFC.

tp->bytes_acked was added in linux-4.2

Following packetdrill test (courtesy of Yepeng Pan) shows
the issue at hand:

0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
+0 bind(3, ..., ...) = 0
+0 listen(3, 1024) = 0

// ---------------- Handshake ------------------- //

// when window scale is set to 14 the window size can be extended to
// 65535 * (2^14) = 1073725440. Linux would accept an ACK packet
// with ack number in (Server_ISN+1-1073725440. Server_ISN+1)
// ,though this ack number acknowledges some data never
// sent by the server.

+0 < S 0:0(0) win 65535 <mss 1400,nop,wscale 14>
+0 > S. 0:0(0) ack 1 <...>
+0 < . 1:1(0) ack 1 win 65535
+0 accept(3, ..., ...) = 4

// For the established connection, we send an ACK packet,
// the ack packet uses ack number 1 - 1073725300 + 2^32,
// where 2^32 is used to wrap around.
// Note: we used 1073725300 instead of 1073725440 to avoid possible
// edge cases.
// 1 - 1073725300 + 2^32 = 3221241997

// Oops, old kernels happily accept this packet.

Florian Westphal c9704c2619 netfilter: nf_tables: fix 'exist' matching on bigendian arches
[ Upstream commit 63331e37fb227e796894b31d713697612c8dee7f ]

Maze reports "tcp option fastopen exists" fails to match on
OpenWrt 22.03.5, r20134-5f15225c1e (5.10.176) router.

"tcp option fastopen exists" translates to:
inet
  [ exthdr load tcpopt 1b @ 34 + 0 present => reg 1 ]
  [ cmp eq reg 1 0x00000001 ]

.. but existing nft userspace generates a 1-byte compare.

On LSB (x86), "*reg32 = 1" is identical to nft_reg_store8(reg32, 1), but
not on MSB, which will place the 1 last. IOW, on bigendian aches the cmp8
is awalys false.

Make sure we store this in a consistent fashion, so existing userspace
will also work on MSB (bigendian).

Regardless of this patch we can also change nft userspace to generate
'reg32 == 0' and 'reg32 != 0' instead of u8 == 0 // u8 == 1 when
adding 'option x missing/exists' expressions as well.
