commit 659ae9d02cb5d72c76f74fff7441eb8fb64d8f5c upstream.

nvmet_pci_epf_create_cq() calls nvmet_cq_create(), which takes a
reference on the controller and installs the completion queue. If the
subsequent PCI address-space mapping fails or returns a too-small partial
mapping, the function jumps to err_internal / err_unmap_queue without
calling nvmet_cq_put(). The matching put in nvmet_pci_epf_delete_cq() is
gated on NVMET_PCI_EPF_Q_LIVE, which is only set after the mapping
succeeds, so teardown never releases these references. A remote PCI host
that drives Create IO CQ commands with a failing PRP1/pci_addr therefore
leaks the CQ and a controller reference on each attempt.

Drop the CQ reference on the mapping-failure paths. The err_internal and
err_unmap_queue labels are only reachable after nvmet_cq_create() has
succeeded, so this pairs the create/put correctly.

commit c9e9bb757971485b4e8414b1744507af186d72c9 upstream.

nvmet_pci_epf_exec_iod_work() submits an I/O command with req->execute()
and then waits for the command to complete and transfers the data back
to the host. This wait is not needed for commands that do not transfer
data from the device to the host. To decide whether that wait is needed,
it reads iod->data_len and iod->dma_dir after calling req->execute().

However, once req->execute() is called, the command may complete
asynchronously on another CPU. For commands that do not require a
device-to-host data transfer, nvmet_pci_epf_queue_response() calls
nvmet_pci_epf_complete_iod() directly, which can free the iod before it
reads iod->data_len and iod->dma_dir, resulting in the KFENCE use-after-
free:

Fix this by referring to iod->data_len and iod->dma_dir before calling
req->execute(). The remaining iod accesses such as iod->status are only
reached on the device-to-host read path. In this case,
nvmet_pci_epf_queue_response() signals iod->done instead of freeing the
iod, so the iod stays valid.

commit 737a3b535247226f6e1a7988fd9d6e63e7d6fc71 upstream.

When fuzzing the nvme target code, I tripped a kernel warning in
nvmet_tcp_map_data() because the length passed into the allocator is
controlled by the remote initiator.

A remote initiator that sends a command with an SGL claiming a huge
number, can create a scatterlist and iovec allocation of over 1 million
entries, which causes the backing kmalloc call to exceed MAX_PAGE_ORDER
and then the page allocator will trip on a WARN_ON_ONCE_GFP() message:

  WARNING: mm/page_alloc.c:5280 __alloc_frozen_pages_noprof
  Workqueue: nvmet_tcp_wq nvmet_tcp_io_work
  ...
  sgl_alloc_order
  nvmet_tcp_map_data
  nvmet_tcp_try_recv_pdu

As it's never good to trip a kernel warning remotely due to many systems
having panic-on-warn enabled, let's silence it by just add GFP_NOWARN to
the allocation flags.

commit 4a3f00262a044e8e15064b1a6860968bf0500bf4 upstream.

nvmet_tcp_map_data() reads the host-controlled 32-bit sgl->length
and, for the in-capsule offset descriptor (type 0x01), checks it
against port->inline_data_size before use. Any other SGL descriptor
type -- including the non-inline transport SGL data-block descriptor
(type (NVME_TRANSPORT_SGL_DATA_DESC << 4) | NVME_SGL_FMT_TRANSPORT_A,
the type a real host uses for out-of-capsule writes) skips that check
entirely and falls straight through to:

	cmd->req.sg = sgl_alloc(len, GFP_KERNEL, &cmd->req.sg_cnt);

with len taken directly from the wire, unbounded up to 4 GiB.

nvmet_req_init() only parses the command and never inspects
sgl->length, and nvmet_check_transfer_len() -- the only other place
transfer_len is validated -- runs later, from req->execute(), after
the allocation has already happened. For a write command the target
responds with an R2T and parks the command waiting for the host to
send the data; if the host (or an unauthenticated peer that simply
never follows up) never does, the sgl_alloc() buffer stays resident
for the life of the command. NVMe/TCP has no mandatory authentication
in the default configuration, so any peer able to reach the target
portal and complete a Fabrics connect can drive this with a single
crafted command, repeatable across queues and connections for
amplification. This is unbounded kernel memory allocation
triggered by a remote, effectively unauthenticated peer.

Validate len against the same NVMET_TCP_MAXH2CDATA ceiling this file
already uses to bound per-PDU H2C data, for every SGL descriptor type,
before doing any allocation. This closes the gap for the non-inline
descriptor while leaving the existing, tighter inline_data_size check
in place for the in-capsule case.

Runtime-verified on a v6.19 KASAN stand: with this bound in place, a
crafted write command carrying an oversized non-inline SGL length is
rejected before sgl_alloc() runs, where the same request previously
drove an unbounded ~256 MiB kernel allocation (up to 4 GiB) that
stayed resident pending an R2T the host never satisfies.

commit ba98d6796d12258e837ece065d2ecb59d76ce4ff upstream.

nvmet_fc_alloc_ls_iodlist() advances iod while initializing the LS IOD
array. If an rqstbuf allocation or response buffer DMA mapping fails,
the unwind loop decrements iod past the start of the array. The final
kfree(iod) therefore frees an address before the allocated object.

This can be reproduced with nvme-fcloop and failslab by setting
fail-nth to 6 before creating a target port. KASAN reports:

  BUG: KASAN: invalid-free in nvmet_fc_register_targetport
  Free of addr ffff88816cf8ff48 by task nvmet_fail_nth/9552

Free the original allocation base stored in tgtport->iod instead. With
this fix applied, the same sysfs write with fail-nth=6 returns -ENOMEM
without any KASAN report.

commit 3ddcfb013322aa37eaa7a0d344b73079c38dfa21 upstream.

nvmet_execute_auth_receive() allocates the response buffer with kmalloc()
sized by the host-supplied AUTH_RECEIVE allocation length, but the
DH-HMAC-CHAP builders write only a fixed-size message into it. The full
allocation length is then copied to the wire by nvmet_copy_to_sgl(), so a
remote initiator receives the bytes past the built message -- up to nearly
a page of uninitialized slab -- during the pre-authentication handshake.

Allocate the buffer with kzalloc() so the unwritten tail is zeroed before
it is sent; conforming responses are unaffected.

commit 79aba4c9403419d822972d2851f2a96a2c0531cf upstream.

When a host issues an Identify command with CNS 07h (Active Namespace ID
List for a specific I/O Command Set), nvmet_execute_identify_nslist() is
called with match_css set. The command-set filter dereferences req->ns,
but this handler never calls nvmet_req_find_ns(), so req->ns is always
NULL (nvmet_req_init() resets it to NULL). As soon as an enabled
namespace with an NSID greater than the requested value exists,
req->ns->csi dereferences a NULL pointer and oopses.

Besides the crash, the comparison is logically wrong: to filter the list
by command set it must test the command set of the namespace being
iterated, not a single fixed value. Use the loop variable ns->csi.

     since DBI may be inaccessible after PME_Turn_Off (Krishna Chaitanya
     Chundru)

   - Power down PHY via PARF_PHY_CTRL before disabling rails/clocks to
     avoid power leakage (Krishna Chaitanya Chundru)

   - Decide whether suspend should put the link in L2 and power down
     using pci_host_common_d3cold_possible() instead of checking whether
     ASPM L1 is enabled (Krishna Chaitanya Chundru)

   - Add qcom D3cold support to tear down interconnect bandwidth and OPP
     votes (Krishna Chaitanya Chundru)

   - Handle unsupported mixed PERST#/PHY DT configurations, e.g., PHY in
     RP node while PERST# is in the RC node, but warn about the DT issue
     (Qiang Yu)

   - Program T_POWER_ON based on DT 't-power-on-us' property in case
     hardware advertises incorrect values (Krishna Chaitanya Chundru)

   - Disable ASPM L0s for SA8775P (Shawn Guo)

   - Initialize DWC MSI lock for firmware-managed ECAM hosts, which
     don't use the dw_pcie_host_init() path that initializes the lock
     (Yadu M G)

  Renesas RZ/G3S PCIe controller driver:

   - Add RZ/V2N DT support (Lad Prabhakar)

  SOPHGO PCIe controller driver:

   - Add 'dma-coherent' DT property for sg2042-pcie driver (Han Gao)

  Synopsys DesignWare PCIe controller driver:

   - Apply ECRC TLP Digest workaround for all DesignWare cores prior to
     5.10a, not just 4.90a and 5.00a (Manikanta Maddireddy)

   - Use common struct dw_pcie 'mode' rather than duplicating it in
     artpec6, dra7xx, dwc-pcie, and keembay driver structs (Hans Zhang)

   - Use DEFINE_SHOW_ATTRIBUTE for ltssm_status debugfs to reduce
     boilerplate and fix a seq_file memory leak by including a
     .release() callback (Hans Zhang)

   - Fix a signedness bug in fault injection test code (Dan Carpenter)

   - Avoid NULL pointer dereference when tearing down debugfs for
     controller that lacks RAS DES capability (Shuvam Pandey)

  MicroSemi Switchtec management driver:

   - Add Gen6 Device IDs (Ben Reed)

  Miscellaneous:

   - Remove unused gpio.h include from amd-mdb, designware-plat, fu740,
     visconti drivers (Andy Shevchenko)

   - Fix typos in documentation (josh ziegler)

   - Use FIELD_MODIFY() instead of open-coding it (Hans Zhang)"
