+Subject: bonding: implement xdo_dev_state_free and call it after deletion
+
+From: Jianbo Liu <jianbol@nvidia.com>
+
+[ Upstream commit ec13009472f4a756288eb4e18e20a7845da98d10 ]
+
+Add this implementation for bonding, so hardware resources can be
+freed from the active slave after xfrm state is deleted. The netdev
+used to invoke xdo_dev_state_free callback, is saved in the xfrm state
+(xs->xso.real_dev), which is also the bond's active slave. To prevent
+it from being freed, acquire netdev reference before leaving RCU
+read-side critical section, and release it after callback is done.
+
+And call it when deleting all SAs from old active real interface while
+switching current active slave.

+Subject: dmaengine: dw: Add memory bus width verification
+
+From: Serge Semin <fancer.lancer@gmail.com>
+
+[ Upstream commit d04b21bfa1c50a2ade4816cab6fdc91827b346b1 ]
+
+Currently in case of the DEV_TO_MEM or MEM_TO_DEV DMA transfers the memory
+data width (single transfer width) is determined based on the buffer
+length, buffer base address or DMA master-channel max address width
+capability. It isn't enough in case of the channel disabling prior the
+block transfer is finished. Here is what DW AHB DMA IP-core databook says
+regarding the port suspension (DMA-transfer pause) implementation in the
+controller:
+
+"When CTLx.SRC_TR_WIDTH < CTLx.DST_TR_WIDTH and the CFGx.CH_SUSP bit is
+high, the CFGx.FIFO_EMPTY is asserted once the contents of the FIFO do not
+permit a single word of CTLx.DST_TR_WIDTH to be formed. However, there may
+still be data in the channel FIFO, but not enough to form a single
+transfer of CTLx.DST_TR_WIDTH. In this scenario, once the channel is
+disabled, the remaining data in the channel FIFO is not transferred to the
+destination peripheral."
+
+So in case if the port gets to be suspended and then disabled it's
+possible to have the data silently discarded even though the controller
+reported that FIFO is empty and the CTLx.BLOCK_TS indicated the dropped
+data already received from the source device. This looks as if the data
+somehow got lost on a way from the peripheral device to memory and causes
+problems for instance in the DW APB UART driver, which pauses and disables
+the DMA-transfer as soon as the recv data timeout happens. Here is the way
+it looks:
+
+ Memory <------- DMA FIFO <------ UART FIFO <---------------- UART
+ DST_TR_WIDTH -+--------| | |
+ | | | | No more data
+ Current lvl -+--------| |---------+- DMA-burst lvl
+ | | |---------+- Leftover data
+ | | |---------+- SRC_TR_WIDTH
+ -+--------+-------+---------+
+
+In the example above: no more data is getting received over the UART port
+and BLOCK_TS is not even close to be fully received; some data is left in
+the UART FIFO, but not enough to perform a bursted DMA-xfer to the DMA
+FIFO; some data is left in the DMA FIFO, but not enough to be passed
+further to the system memory in a single transfer. In this situation the
+8250 UART driver catches the recv timeout interrupt, pauses the
+DMA-transfer and terminates it completely, after which the IRQ handler
+manually fetches the leftover data from the UART FIFO into the
+recv-buffer. But since the DMA-channel has been disabled with the data
+left in the DMA FIFO, that data will be just discarded and the recv-buffer
+will have a gap of the "current lvl" size in the recv-buffer at the tail
+of the lately received data portion. So the data will be lost just due to
+the misconfigured DMA transfer.
+
+Note this is only relevant for the case of the transfer suspension and
+_disabling_. No problem will happen if the transfer will be re-enabled
+afterwards or the block transfer is fully completed. In the later case the
+"FIFO flush mode" will be executed at the transfer final stage in order to
+push out the data left in the DMA FIFO.
+
+In order to fix the denoted problem the DW AHB DMA-engine driver needs to
+make sure that the _bursted_ source transfer width is greater or equal to
+the single destination transfer (note the HW databook describes more
+strict constraint than actually required). Since the peripheral-device
+side is prescribed by the client driver logic, the memory-side can be only
+used for that. The solution can be easily implemented for the DEV_TO_MEM
+transfers just by adjusting the memory-channel address width. Sadly it's
+not that easy for the MEM_TO_DEV transfers since the mem-to-dma burst size
+is normally dynamically determined by the controller. So the only thing
+that can be done is to make sure that memory-side address width is greater
+than the peripheral device address width.

+Subject: dmaengine: dw: Add peripheral bus width verification
+
+From: Serge Semin <fancer.lancer@gmail.com>
+
+[ Upstream commit b336268dde75cb09bd795cb24893d52152a9191f ]
+
+Currently the src_addr_width and dst_addr_width fields of the
+dma_slave_config structure are mapped to the CTLx.SRC_TR_WIDTH and
+CTLx.DST_TR_WIDTH fields of the peripheral bus side in order to have the
+properly aligned data passed to the target device. It's done just by
+converting the passed peripheral bus width to the encoded value using the
+__ffs() function. This implementation has several problematic sides:
+
+1. __ffs() is undefined if no bit exist in the passed value. Thus if the
+specified addr-width is DMA_SLAVE_BUSWIDTH_UNDEFINED, __ffs() may return
+unexpected value depending on the platform-specific implementation.
+
+2. DW AHB DMA-engine permits having the power-of-2 transfer width limited
+by the DMAH_Mk_HDATA_WIDTH IP-core synthesize parameter. Specifying
+bus-width out of that constraints scope will definitely cause unexpected
+result since the destination reg will be only partly touched than the
+client driver implied.
+
+Let's fix all of that by adding the peripheral bus width verification
+method and calling it in dwc_config() which is supposed to be executed
+before preparing any transfer. The new method will make sure that the
+passed source or destination address width is valid and if undefined then
+the driver will just fallback to the 1-byte width transfer.

+
+From: Cong Wang <cong.wang@bytedance.com>
+
+[ Upstream commit defd8b3c37b0f9cb3e0f60f47d3d78d459d57fda ]
+
+When sockfd_lookup() fails, gtp_encap_enable_socket() returns a
+NULL pointer, but its callers only check for error pointers thus miss
+the NULL pointer case.
+
+Fix it by returning an error pointer with the error code carried from
+sockfd_lookup().

+Subject: iommu: Do not return 0 from map_pages if it doesn't do anything
+
+From: Jason Gunthorpe <jgg@nvidia.com>
+
+[ Upstream commit 6093cd582f8e027117a8d4ad5d129a1aacdc53d2 ]
+
+These three implementations of map_pages() all succeed if a mapping is
+requested with no read or write. Since they return back to __iommu_map()
+leaving the mapped output as 0 it triggers an infinite loop. Therefore
+nothing is using no-access protection bits.
+
+Further, VFIO and iommufd rely on iommu_iova_to_phys() to get back PFNs
+stored by map, if iommu_map() succeeds but iommu_iova_to_phys() fails that
+will create serious bugs.
+
+Thus remove this never used "nothing to do" concept and just fail map
+immediately.

+
+Typically, busy-polling durations are below 100 usec.
+
+When/if the busy-poller thread migrates to another cpu,
+local_clock() can be off by +/-2msec or more for small

+
+From: Pablo Neira Ayuso <pablo@netfilter.org>
+
+[ Upstream commit 5fd0628918977a0afdc2e6bc562d8751b5d3b8c5 ]
+
+Subtract network offset to skb->len before performing IPv4 header sanity
+checks, then adjust transport offset from offset from mac header.
+
+Jorge Ortiz says:
+
+When small UDP packets (< 4 bytes payload) are sent from eth0,
+`meta l4proto udp` condition is not met because `NFT_PKTINFO_L4PROTO` is
+not set. This happens because there is a comparison that checks if the
+transport header offset exceeds the total length. This comparison does
+not take into account the fact that the skb network offset might be
+non-zero in egress mode (e.g., 14 bytes for Ethernet header).

+
+From: Aleksandr Mishin <amishin@t-argos.ru>
+
+[ Upstream commit febccb39255f9df35527b88c953b2e0deae50e53 ]
+
+In case of im_protocols value is 1 and tm_protocols value is 0 this
+combination successfully passes the check
+'if (!im_protocols && !tm_protocols)' in the nfc_start_poll().
+But then after pn533_poll_create_mod_list() call in pn533_start_poll()
+poll mod list will remain empty and dev->poll_mod_count will remain 0
+which lead to division by zero.
+
+Normally no im protocol has value 1 in the mask, so this combination is
+not expected by driver. But these protocol values actually come from
+userspace via Netlink interface (NFC_CMD_START_POLL operation). So a
+broken or malicious program may pass a message containing a "bad"
+combination of protocol parameter values so that dev->poll_mod_count
+is not incremented inside pn533_poll_create_mod_list(), thus leading
+to division by zero.
+Call trace looks like:
+nfc_genl_start_poll()
+ nfc_start_poll()
+ ->start_poll()
+ pn533_start_poll()
+
+Add poll mod list filling check.

+
+From: Piyush Mehta <piyush.mehta@amd.com>
+
+[ Upstream commit 25d70083351318b44ae699d92c042dcb18a738ea ]
+
+Enabling clock for all the lanes consumes power even PHY is active or
+inactive. To resolve this, enable/disable clocks in phy_init/phy_exit.
+
+By default clock is disabled for all the lanes. Whenever phy_init called
+from USB, SATA, or display driver, etc. It enabled the required clock
+for requested lane. On phy_exit cycle, it disabled clock for the active
+PHYs.
+
+During the suspend/resume cycle, each USB/ SATA/ display driver called
+phy_exit/phy_init individually. It disabled clock on exit, and enabled
+on initialization for the active PHYs.

+Subject: phy: xilinx: phy-zynqmp: Fix SGMII linkup failure on resume
+
+From: Piyush Mehta <piyush.mehta@amd.com>
+
+[ Upstream commit 5af9b304bc6010723c02f74de0bfd24ff19b1a10 ]
+
+On a few Kria KR260 Robotics Starter Kit the PS-GEM SGMII linkup is not
+happening after the resume. This is because serdes registers are reset
+when FPD is off (in suspend state) and needs to be reprogrammed in the
+resume path with the same default initialization as done in the first
+stage bootloader psu_init routine.
+
+To address the failure introduce a set of serdes registers to be saved in
+the suspend path and then restore it on resume.

+Subject: sctp: fix association labeling in the duplicate COOKIE-ECHO case
+
+From: Ondrej Mosnacek <omosnace@redhat.com>
+
+[ Upstream commit 3a0504d54b3b57f0d7bf3d9184a00c9f8887f6d7 ]
+
+sctp_sf_do_5_2_4_dupcook() currently calls security_sctp_assoc_request()
+on new_asoc, but as it turns out, this association is always discarded
+and the LSM labels never get into the final association (asoc).
+
+This can be reproduced by having two SCTP endpoints try to initiate an
+association with each other at approximately the same time and then peel
+off the association into a new socket, which exposes the unitialized
+labels and triggers SELinux denials.
+
+Fix it by calling security_sctp_assoc_request() on asoc instead of
+new_asoc. Xin Long also suggested limit calling the hook only to cases
+A, B, and D, since in cases C and E the COOKIE ECHO chunk is discarded
+and the association doesn't enter the ESTABLISHED state, so rectify that
+as well.
+
+One related caveat with SELinux and peer labeling: When an SCTP
+connection is set up simultaneously in this way, we will end up with an
+association that is initialized with security_sctp_assoc_request() on
+both sides, so the MLS component of the security context of the
+association will get swapped between the peers, instead of just one side
+setting it to the other's MLS component. However, at that point
+security_sctp_assoc_request() had already been called on both sides in
+sctp_sf_do_unexpected_init() (on a temporary association) and thus if
+the exchange didn't fail before due to MLS, it won't fail now either
+(most likely both endpoints have the same MLS range).
+
+Tested by:
+ - reproducer from https://src.fedoraproject.org/tests/selinux/pull-request/530
+ - selinux-testsuite (https://github.com/SELinuxProject/selinux-testsuite/)
+ - sctp-tests (https://github.com/sctp/sctp-tests) - no tests failed
+ that wouldn't fail also without the patch applied

+Subject: wifi: iwlwifi: fw: fix wgds rev 3 exact size
+
+From: Anjaneyulu <pagadala.yesu.anjaneyulu@intel.com>
+
+[ Upstream commit 3ee22f07a35b76939c5b8d17d6af292f5fafb509 ]
+
+Check size of WGDS revision 3 is equal to 8 entries size with some header,
+but doesn't depend on the number of used entries. Check that used entries
+are between min and max but allow more to be present than are used to fix
+operation with some BIOSes that have such data.
