wifi: rtw89: wow: refine WoWLAN flows of HCI interrupts and low power…
… mode [ Upstream commit baaf806 ] After enabling packet offload, the TX will be stuck after resume from WoWLAN mode. And the 8852c gets error messages like rtw89_8852ce 0000:04:00.0: No busy txwd pages available rtw89_8852ce 0000:04:00.0: queue 0 txwd 100 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 101 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 102 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 103 is not idle If suspend/resume many times that firmware will download failed and disconnection. To fix these issues, We removed the rtw89_hci_disable_intr() and rtw89_hci_enable_intr() during rtw89_wow_swap_fw() to prevent add packet offload can't receive c2h back due to interrupt disable. Only 8852C and 8922A needs to disable interrupt before downloading fw. Furthermore, we avoid using low power HCI mode on WoWLAN mode, to prevent interrupt enabled, then get interrupt and calculate RXBD mismatched due to software RXBD index already reset but hardware RXBD index not yet.

selftests/binderfs: use the Makefile's rules, not Make's implicit rules
[ Upstream commit 019baf6 ] First of all, in order to build with clang at all, one must first apply Valentin Obst's build fix for LLVM [1]. Once that is done, then when building with clang, via: make LLVM=1 -C tools/testing/selftests ...the following error occurs: clang: error: cannot specify -o when generating multiple output files This is because clang, unlike gcc, won't accept invocations of this form: clang file1.c header2.h While trying to fix this, I noticed that: a) selftests/lib.mk already avoids the problem, and b) The binderfs Makefile indavertently bypasses the selftests/lib.mk build system, and quitely uses Make's implicit build rules for .c files instead. The Makefile attempts to set up both a dependency and a source file, neither of which was needed, because lib.mk is able to automatically handle both. This line: binderfs_test: binderfs_test.c ...causes Make's implicit rules to run, which builds binderfs_test without ever looking at lib.mk. Fix this by simply deleting the "binderfs_test:" Makefile target and letting lib.mk handle it instead.

selftests: default to host arch for LLVM builds
[ Upstream commit d4e6fbd ] Align the behavior for gcc and clang builds by interpreting unset `ARCH` and `CROSS_COMPILE` variables in `LLVM` builds as a sign that the user wants to build for the host architecture. This patch preserves the properties that setting the `ARCH` variable to an unknown value will trigger an error that complains about insufficient information, and that a set `CROSS_COMPILE` variable will override the target triple that is determined based on presence/absence of `ARCH`. When compiling with clang, i.e., `LLVM` is set, an unset `ARCH` variable in combination with an unset `CROSS_COMPILE` variable, i.e., compiling for the host architecture, leads to compilation failures since `lib.mk` can not determine the clang target triple. In this case, the following error message is displayed for each subsystem that does not set `ARCH` in its own Makefile before including `lib.mk` (lines wrapped at 75 chrs): make[1]: Entering directory '/mnt/build/linux/tools/testing/selftests/ sysctl' ../lib.mk:33: *** Specify CROSS_COMPILE or add '--target=' option to lib.mk. Stop. make[1]: Leaving directory '/mnt/build/linux/tools/testing/selftests/ sysctl' In the same scenario a gcc build would default to the host architecture, i.e., it would use plain `gcc`.

…uites to test [ Upstream commit 5496b9b ] Commit c72a870 added a mutex to prevent kunit tests from running concurrently. Unfortunately that mutex gets locked during module load regardless of whether the module actually has any kunit tests. This causes a problem for kunit tests that might need to load other kernel modules (e.g. gss_krb5_test loading the camellia module). So check to see if there are actually any tests to run before locking the kunit_run_lock mutex.

selftests/bpf: Fix pointer arithmetic in test_xdp_do_redirect
[ Upstream commit e549b39 ] Cast operation has a higher precedence than addition. The code here wants to zero the 2nd half of the 64-bit metadata, but due to a pointer arithmetic mistake, it writes the zero at offset 16 instead. Just adding parentheses around "data + 4" would fix this, but I think this will be slightly better readable with array syntax. I was unable to test this with tools/testing/selftests/bpf/vmtest.sh, because my glibc is newer than glibc in the provided VM image. So I just checked the difference in the compiled code. objdump -S tools/testing/selftests/bpf/xdp_do_redirect.test.o: - *((__u32 *)data) = 0x42; /* metadata test value */ + ((__u32 *)data)[0] = 0x42; /* metadata test value */ be7: 48 8d 85 30 fc ff ff lea -0x3d0(%rbp),%rax bee: c7 00 42 00 00 00 movl $0x42,(%rax) - *((__u32 *)data + 4) = 0; + ((__u32 *)data)[1] = 0; bf4: 48 8d 85 30 fc ff ff lea -0x3d0(%rbp),%rax - bfb: 48 83 c0 10 add $0x10,%rax + bfb: 48 83 c0 04 add $0x4,%rax bff: c7 00 00 00 00 00 movl $0x0,(%rax) Fixes: 5640b6d ("selftests/bpf: fix "metadata marker" getting overwritten by the netstack") Signed-off-by: Michal Schmidt <mschmidt@redhat.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Reviewed-by: Toke Høiland-Jørgensen <toke@redhat.com> Link: https://lore.kernel.org/bpf/20240506145023.214248-1-mschmidt@redhat.com Signed-off-by: Sasha Levin <sashal@kernel.org>

x86/numa: Fix SRAT lookup of CFMWS ranges with numa_fill_memblks()
[ Upstream commit f9f67e5 ] For configurations that have the kconfig option NUMA_KEEP_MEMINFO disabled, numa_fill_memblks() only returns with NUMA_NO_MEMBLK (-1). SRAT lookup fails then because an existing SRAT memory range cannot be found for a CFMWS address range. This causes the addition of a duplicate numa_memblk with a different node id and a subsequent page fault and kernel crash during boot. Fix this by making numa_fill_memblks() always available regardless of NUMA_KEEP_MEMINFO. As Dan suggested, the fix is implemented to remove numa_fill_memblks() from sparsemem.h and alos using __weak for the function. Note that the issue was initially introduced with [1]. But since phys_to_target_node() was originally used that returned the valid node 0, an additional numa_memblk was not added. Though, the node id was wrong too, a message is seen then in the logs: kernel/numa.c: pr_info_once("Unknown target node for memory at 0x%llx, assuming node 0\n", [1] commit fd49f99 ("ACPI: NUMA: Add a node and memblk for each CFMWS not in SRAT") Suggested-by: Dan Williams <dan.j.williams@intel.com> Link: https://lore.kernel.org/all/66271b0072317_69102944c@dwillia2-xfh.jf.intel.com.notmuch/ Fixes: 8f10046 ("ACPI/NUMA: Apply SRAT proximity domain to entire CFMWS window") Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Alison Schofield <alison.schofield@intel.com> Reviewed-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: Robert Richter <rrichter@amd.com> Acked-by: Borislav Petkov (AMD) <bp@alien8.de> Signed-off-by: Rafael J.

btrfs: set start on clone before calling copy_extent_buffer_full
[ Upstream commit 53e2415 ] Our subpage testing started hanging on generic/560 and I bisected it down to 1cab137 ("btrfs: reuse cloned extent buffer during fiemap to avoid re-allocations"). This is subtle because we use eb->start to figure out where in the folio we're copying to when we're subpage, as our ->start may refer to an area inside of the folio. For example, assume a 16K page size machine with a 4K node size, and assume that we already have a cloned extent buffer when we cloned the previous search. copy_extent_buffer_full() will do the following when copying the extent buffer path->nodes[0] (src) into cloned (dest): src->start = 8k; // this is the new leaf we're cloning cloned->start = 4k; // this is left over from the previous clone src_addr = folio_address(src->folios[0]); dest_addr = folio_address(dest->folios[0]); memcpy(dest_addr + get_eb_offset_in_folio(dst, 0), src_addr + get_eb_offset_in_folio(src, 0), src->len); Now get_eb_offset_in_folio() is where the problems occur, because for sub-pagesize blocksize we can have multiple eb's per folio, the code for this is as follows size_t get_eb_offset_in_folio(eb, offset) { return (eb->start + offset & (folio_size(eb->folio[0]) - 1)); } So in the above example we are copying into offset 4K inside the folio. However once we update cloned->start to 8K to match the src the math for get_eb_offset_in_folio() changes, and any subsequent reads (i.e. btrfs_item_key_to_cpu()) will start reading from the offset 8K instead of 4K where we copied to, giving us garbage. Fix this by setting start before we co copy_extent_buffer_full() to make sure that we're copying into the same offset inside of the folio that we will read from later. All other sites of copy_extent_buffer_full() are correct because we either set ->start beforehand or we simply don't change it in the case of the tree-log usage. With this fix we now pass generic/560 on our subpage tests.

m68k: Fix spinlock race in kernel thread creation
[ Upstream commit da89ce4 ] Context switching does take care to retain the correct lock owner across the switch from 'prev' to 'next' tasks. This does rely on interrupts remaining disabled for the entire duration of the switch. This condition is guaranteed for normal process creation and context switching between already running processes, because both 'prev' and 'next' already have interrupts disabled in their saved copies of the status register. The situation is different for newly created kernel threads. The status register is set to PS_S in copy_thread(), which does leave the IPL at 0. Upon restoring the 'next' thread's status register in switch_to() aka resume(), interrupts then become enabled prematurely. resume() then returns via ret_from_kernel_thread() and schedule_tail() where run queue lock is released (see finish_task_switch() and finish_lock_switch()). A timer interrupt calling scheduler_tick() before the lock is released in finish_task_switch() will find the lock already taken, with the current task as lock owner. This causes a spinlock recursion warning as reported by Guenter Roeck. As far as I can ascertain, this race has been opened in commit 533e690 ("m68k: split ret_from_fork(), simplify kernel_thread()") but I haven't done a detailed study of kernel history so it may well predate that commit. Interrupts cannot be disabled in the saved status register copy for kernel threads (init will complain about interrupts disabled when finally starting user space). Disable interrupts temporarily when switching the tasks' register sets in resume(). Note that a simple oriw 0x700,%sr after restoring sr is not enough here - this leaves enough of a race for the 'spinlock recursion' warning to still be observed. Tested on ARAnyM and qemu (Quadra 800 emulation).

m68k: mac: Fix reboot hang on Mac IIci
[ Upstream commit 265a3b3 ] Calling mac_reset() on a Mac IIci does reset the system, but what follows is a POST failure that requires a manual reset to resolve. Avoid that by using the 68030 asm implementation instead of the C implementation. Apparently the SE/30 has a similar problem as it has used the asm implementation since before git. This patch extends that solution to other systems with a similar ROM. After this patch, the only systems still using the C implementation are 68040 systems where adb_type is either MAC_ADB_IOP or MAC_ADB_II. This implies a 1 MiB Quadra ROM. This now includes the Quadra 900/950, which previously fell through to the "should never get here" catch-all.

dm-delay: fix workqueue delay_timer race
[ Upstream commit 8d24790 ] delay_timer could be pending when delay_dtr() is called. It needs to be shut down before kdelayd_wq is destroyed, so it won't try queueing more work to kdelayd_wq while that's getting destroyed. Also the del_timer_sync() call in delay_presuspend() doesn't protect against the timer getting immediately rearmed by the queued call to flush_delayed_bios(), but there's no real harm if that does happen. timer_delete() is less work, and is basically just as likely to stop a pointless call to flush_delayed_bios().

net: ipv6: fix wrong start position when receive hop-by-hop fragment
[ Upstream commit 1cd354f ] In IPv6, ipv6_rcv_core will parse the hop-by-hop type extension header and increase skb->transport_header by one extension header length. But if there are more other extension headers like fragment header at this time, the skb->transport_header points to the second extension header, not the transport layer header or the first extension header. This will result in the start and nexthdrp variable not pointing to the same position in ipv6frag_thdr_trunced, and ipv6_skip_exthdr returning incorrect offset and frag_off.Sometimes,the length of the last sharded packet is smaller than the calculated incorrect offset, resulting in packet loss.

net: openvswitch: fix overwriting ct original tuple for ICMPv6
[ Upstream commit 7c98817 ] OVS_PACKET_CMD_EXECUTE has 3 main attributes: - OVS_PACKET_ATTR_KEY - Packet metadata in a netlink format. - OVS_PACKET_ATTR_PACKET - Binary packet content. - OVS_PACKET_ATTR_ACTIONS - Actions to execute on the packet. OVS_PACKET_ATTR_KEY is parsed first to populate sw_flow_key structure with the metadata like conntrack state, input port, recirculation id, etc. Then the packet itself gets parsed to populate the rest of the keys from the packet headers. Whenever the packet parsing code starts parsing the ICMPv6 header, it first zeroes out fields in the key corresponding to Neighbor Discovery information even if it is not an ND packet. It is an 'ipv6.nd' field. However, the 'ipv6' is a union that shares the space between 'nd' and 'ct_orig' that holds the original tuple conntrack metadata parsed from the OVS_PACKET_ATTR_KEY. ND packets should not normally have conntrack state, so it's fine to share the space, but normal ICMPv6 Echo packets or maybe other types of ICMPv6 can have the state attached and it should not be overwritten. The issue results in all but the last 4 bytes of the destination address being wiped from the original conntrack tuple leading to incorrect packet matching and potentially executing wrong actions in case this packet recirculates within the datapath or goes back to userspace. ND fields should not be accessed in non-ND packets, so not clearing them should be fine. Executing memset() only for actual ND packets to avoid the issue. Initializing the whole thing before parsing is needed because ND packet may not contain all the options. The issue only affects the OVS_PACKET_CMD_EXECUTE path and doesn't affect packets entering OVS datapath from network interfaces, because in this case CT metadata is populated from skb after the packet is already parsed.

net/mlx5e: Fix netif state handling

net/mlx5: Reload only IB representors upon lag disable/enable
[ Upstream commit 0f06228 ] On lag disable, the bond IB device along with all of its representors are destroyed, and then the slaves' representors get reloaded. In case the slave IB representor load fails, the eswitch error flow unloads all representors, including ethernet representors, where the netdevs get detached and removed from lag bond. Such flow is inaccurate as the lag driver is not responsible for loading/unloading ethernet representors. Furthermore, the flow described above begins by holding lag lock to prevent bond changes during disable flow. However, when reaching the ethernet representors detachment from lag, the lag lock is required again, triggering the following deadlock: Call trace: __switch_to+0xf4/0x148 __schedule+0x2c8/0x7d0 schedule+0x50/0xe0 schedule_preempt_disabled+0x18/0x28 __mutex_lock.isra.13+0x2b8/0x570 __mutex_lock_slowpath+0x1c/0x28 mutex_lock+0x4c/0x68 mlx5_lag_remove_netdev+0x3c/0x1a0 [mlx5_core] mlx5e_uplink_rep_disable+0x70/0xa0 [mlx5_core] mlx5e_detach_netdev+0x6c/0xb0 [mlx5_core] mlx5e_netdev_change_profile+0x44/0x138 [mlx5_core] mlx5e_netdev_attach_nic_profile+0x28/0x38 [mlx5_core] mlx5e_vport_rep_unload+0x184/0x1b8 [mlx5_core] mlx5_esw_offloads_rep_load+0xd8/0xe0 [mlx5_core] mlx5_eswitch_reload_reps+0x74/0xd0 [mlx5_core] mlx5_disable_lag+0x130/0x138 [mlx5_core] mlx5_lag_disable_change+0x6c/0x70 [mlx5_core] // hold ldev->lock mlx5_devlink_eswitch_mode_set+0xc0/0x410 [mlx5_core] devlink_nl_cmd_eswitch_set_doit+0xdc/0x180 genl_family_rcv_msg_doit.isra.17+0xe8/0x138 genl_rcv_msg+0xe4/0x220 netlink_rcv_skb+0x44/0x108 genl_rcv+0x40/0x58 netlink_unicast+0x198/0x268 netlink_sendmsg+0x1d4/0x418 sock_sendmsg+0x54/0x60 __sys_sendto+0xf4/0x120 __arm64_sys_sendto+0x30/0x40 el0_svc_common+0x8c/0x120 do_el0_svc+0x30/0xa0 el0_svc+0x20/0x30 el0_sync_handler+0x90/0xb8 el0_sync+0x160/0x180 Thus, upon lag enable/disable, load and unload only the IB representors of the slaves preventing the deadlock mentioned above.

s390/bpf: Emit a barrier for BPF_FETCH instructions
[ Upstream commit 6837898 ] BPF_ATOMIC_OP() macro documentation states that "BPF_ADD | BPF_FETCH" should be the same as atomic_fetch_add(), which is currently not the case on s390x: the serialization instruction "bcr 14,0" is missing. This applies to "and", "or" and "xor" variants too. s390x is allowed to reorder stores with subsequent fetches from different addresses, so code relying on BPF_FETCH acting as a barrier, for example: stw [%r0], 1 afadd [%r1], %r2 ldxw %r3, [%r4] may be broken. Fix it by emitting "bcr 14,0". Note that a separate serialization instruction is not needed for BPF_XCHG and BPF_CMPXCHG, because COMPARE AND SWAP performs serialization itself.

riscv, bpf: make some atomic operations fully ordered
[ Upstream commit 20a759d ] The BPF atomic operations with the BPF_FETCH modifier along with BPF_XCHG and BPF_CMPXCHG are fully ordered but the RISC-V JIT implements all atomic operations except BPF_CMPXCHG with relaxed ordering. Section 8.1 of the "The RISC-V Instruction Set Manual Volume I: Unprivileged ISA" [1], titled, "Specifying Ordering of Atomic Instructions" says: | To provide more efficient support for release consistency [5], each | atomic instruction has two bits, aq and rl, used to specify additional | memory ordering constraints as viewed by other RISC-V harts. and | If only the aq bit is set, the atomic memory operation is treated as | an acquire access. | If only the rl bit is set, the atomic memory operation is treated as a | release access. | | If both the aq and rl bits are set, the atomic memory operation is | sequentially consistent. Fix this by setting both aq and rl bits as 1 for operations with BPF_FETCH and BPF_XCHG.

ax25: Use kernel universal linked list to implement ax25_dev_list
[ Upstream commit a7d6e36 ] The origin ax25_dev_list implements its own single linked list, which is complicated and error-prone. For example, when deleting the node of ax25_dev_list in ax25_dev_device_down(), we have to operate on the head node and other nodes separately. This patch uses kernel universal linked list to replace original ax25_dev_list, which make the operation of ax25_dev_list easier. We should do "dev->ax25_ptr = ax25_dev;" and "dev->ax25_ptr = NULL;" while holding the spinlock, otherwise the ax25_dev_device_up() and ax25_dev_device_down() could race.

ax25: Fix reference count leak issues of ax25_dev
[ Upstream commit b505e03 ] The ax25_addr_ax25dev() and ax25_dev_device_down() exist a reference count leak issue of the object "ax25_dev". Memory leak issue in ax25_addr_ax25dev(): The reference count of the object "ax25_dev" can be increased multiple times in ax25_addr_ax25dev(). This will cause a memory leak. Memory leak issues in ax25_dev_device_down(): The reference count of ax25_dev is set to 1 in ax25_dev_device_up() and then increase the reference count when ax25_dev is added to ax25_dev_list. As a result, the reference count of ax25_dev is 2. But when the device is shutting down. The ax25_dev_device_down() drops the reference count once or twice depending on if we goto unlock_put or not, which will cause memory leak. As for the issue of ax25_addr_ax25dev(), it is impossible for one pointer to be on a list twice. So add a break in ax25_addr_ax25dev(). As for the issue of ax25_dev_device_down(), increase the reference count of ax25_dev once in ax25_dev_device_up() and decrease the reference count of ax25_dev after it is removed from the ax25_dev_list.

When the ax25 device is shutting down, the ax25_dev_device_down() drops the reference count of net_device one or zero times depending on if we goto unlock_put or not, which will cause memory leak. In order to solve the above issue, decrease the reference count of net_device after dev->ax25_ptr is set to null.

net: fec: remove .ndo_poll_controller to avoid deadlocks
[ Upstream commit c2e0c58 ] There is a deadlock issue found in sungem driver, please refer to the commit ac0a230 ("eth: sungem: remove .ndo_poll_controller to avoid deadlocks"). The root cause of the issue is that netpoll is in atomic context and disable_irq() is called by .ndo_poll_controller interface of sungem driver, however, disable_irq() might sleep. After analyzing the implementation of fec_poll_controller(), the fec driver should have the same issue. Due to the fec driver uses NAPI for TX completions, the .ndo_poll_controller is unnecessary to be implemented in the fec driver, so fec_poll_controller() can be safely removed.

mptcp: SO_KEEPALIVE: fix getsockopt support
[ Upstream commit a651981 ] SO_KEEPALIVE support has to be set on each subflow: on each TCP socket, where sk_prot->keepalive is defined. Technically, nothing has to be done on the MPTCP socket. That's why mptcp_sol_socket_sync_intval() was called instead of mptcp_sol_socket_intval(). Except that when nothing is done on the MPTCP socket, the getsockopt(SO_KEEPALIVE), handled in net/core/sock.c:sk_getsockopt(), will not know if SO_KEEPALIVE has been set on the different subflows or not. The fix is simple: simply call mptcp_sol_socket_intval() which will end up calling net/core/sock.c:sk_setsockopt() where the SOCK_KEEPOPEN flag will be set, the one used in sk_getsockopt(). So now, getsockopt(SO_KEEPALIVE) on an MPTCP socket will return the same value as the one previously set with setsockopt(SO_KEEPALIVE).

mptcp: fix full TCP keep-alive support
[ Upstream commit bd11dc4 ] SO_KEEPALIVE support has been added a while ago, as part of a series "adding SOL_SOCKET" support. To have a full control of this keep-alive feature, it is important to also support TCP_KEEP* socket options at the SOL_TCP level. Supporting them on the setsockopt() part is easy, it is just a matter of remembering each value in the MPTCP sock structure, and calling tcp_sock_set_keep*() helpers on each subflow. If the value is not modified (0), calling these helpers will not do anything. For the getsockopt() part, the corresponding value from the MPTCP sock structure or the default one is simply returned. All of this is very similar to other TCP_* socket options supported by MPTCP. It looks important for kernels supporting SO_KEEPALIVE, to also support TCP_KEEP* options as well: some apps seem to (wrongly) consider that if the former is supported, the latter ones will be supported as well. But also, not having this simple and isolated change is preventing MPTCP support in some apps, and libraries like GoLang [1]. This is why this patch is seen as a fix.

net: micrel: Fix receiving the timestamp in the frame for lan8841
[ Upstream commit aea27a9 ] The blamed commit started to use the ptp workqueue to get the second part of the timestamp. And when the port was set down, then this workqueue is stopped. But if the config option NETWORK_PHY_TIMESTAMPING is not enabled, then the ptp_clock is not initialized so then it would crash when it would try to access the delayed work. So then basically by setting up and then down the port, it would crash. The fix consists in checking if the ptp_clock is initialized and only then cancel the delayed work.

Bluetooth: compute LE flow credits based on recvbuf space
[ Upstream commit ce60b92 ] Previously LE flow credits were returned to the sender even if the socket's receive buffer was full. This meant that no back-pressure was applied to the sender, thus it continued to send data, resulting in data loss without any error being reported. Furthermore, the amount of credits was essentially fixed to a small amount, leading to reduced performance. This is fixed by computing the number of returned LE flow credits based on the estimated available space in the receive buffer of an L2CAP socket. Consequently, if the receive buffer is full, no credits are returned until the buffer is read and thus cleared by user-space. Since the computation of available receive buffer space can only be performed approximately (due to sk_buff overhead) and the receive buffer size may be changed by user-space after flow credits have been sent, superfluous received data is temporary stored within l2cap_pinfo. This is necessary because Bluetooth LE provides no retransmission mechanism once the data has been acked by the physical layer. If receive buffer space estimation is not possible at the moment, we fall back to providing credits for one full packet as before. This is currently the case during connection setup, when MPS is not yet available.

Bluetooth: hci_conn, hci_sync: Use __counted_by() to avoid -Wfamnae w…
…arnings [ Upstream commit c4585ed ] 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, -Wflex-array-member-not-at-end is coming in GCC-14, and we are getting ready to enable it globally. So, use the `DEFINE_FLEX()` helper for multiple on-stack definitions of a flexible structure where the size of the flexible-array member is known at compile-time, and refactor the rest of the code, accordingly. Notice that, due to the use of `__counted_by()` in `struct hci_cp_le_create_cis`, the for loop in function `hci_cs_le_create_cis()` had to be modified. Once the index `i`, through which `cp->cis[i]` is accessed, falls in the interval [0, cp->num_cis), `cp->num_cis` cannot be decremented all the way down to zero while accessing `cp->cis[]`: net/bluetooth/hci_event.c:4310: 4310 for (i = 0; cp->num_cis; cp->num_cis--, i++) { ... 4314 handle = __le16_to_cpu(cp->cis[i].cis_handle); otherwise, only half (one iteration before `cp->num_cis == i`) or half plus one (one iteration before `cp->num_cis < i`) of the items in the array will be accessed before running into an out-of-bounds issue. So, in order to avoid this, set `cp->num_cis` to zero just after the for loop. Also, make use of `aux_num_cis` variable to update `cmd->num_cis` after a `list_for_each_entry_rcu()` loop. With these changes, fix the following warnings: net/bluetooth/hci_sync.c:1239:56: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] net/bluetooth/hci_sync.c:1415:51: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] net/bluetooth/hci_sync.c:1731:51: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] net/bluetooth/hci_sync.c:6497:45: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Link: KSPP#202 Signed-off-by: Gustavo A.

drm/bridge: Fix improper bridge init order with pre_enable_prev_first
[ Upstream commit e18aeed ] For a given bridge pipeline if any bridge sets pre_enable_prev_first flag then the pre_enable for the previous bridge will be called before pre_enable of this bridge and opposite is done for post_disable. These are the potential bridge flags to alter bridge init order in order to satisfy the MIPI DSI host and downstream panel or bridge to function. However the existing pre_enable_prev_first logic with associated bridge ordering has broken for both pre_enable and post_disable calls. [pre_enable] The altered bridge ordering has failed if two consecutive bridges on a given pipeline enables the pre_enable_prev_first flag. Example: - Panel - Bridge 1 - Bridge 2 pre_enable_prev_first - Bridge 3 - Bridge 4 pre_enable_prev_first - Bridge 5 pre_enable_prev_first - Bridge 6 - Encoder In this example, Bridge 4 and Bridge 5 have pre_enable_prev_first. The logic looks for a bridge which enabled pre_enable_prev_first flag on each iteration and assigned the previou bridge to limit pointer if the bridge doesn't enable pre_enable_prev_first flags. If control found Bridge 2 is pre_enable_prev_first then the iteration looks for Bridge 3 and found it is not pre_enable_prev_first and assigns it's previous Bridge 4 to limit pointer and calls pre_enable of Bridge 3 and Bridge 2 and assign iter pointer with limit which is Bridge 4. Here is the actual problem, for the next iteration control look for Bridge 5 instead of Bridge 4 has iter pointer in previous iteration moved to Bridge 4 so this iteration skips the Bridge 4. The iteration found Bridge 6 doesn't pre_enable_prev_first flags so the limit assigned to Encoder. From next iteration Encoder skips as it is the last bridge for reverse order pipeline. So, the resulting pre_enable bridge order would be, - Panel, Bridge 1, Bridge 3, Bridge 2, Bridge 6, Bridge 5. This patch fixes this by assigning limit to next pointer instead of previous bridge since the iteration always looks for bridge that does NOT request prev so assigning next makes sure the last bridge on a given iteration what exactly the limit bridge is. So, the resulting pre_enable bridge order with fix would be, - Panel, Bridge 1, Bridge 3, Bridge 2, Bridge 6, Bridge 5, Bridge 4, Encoder. [post_disable] The altered bridge ordering has failed if two consecutive bridges on a given pipeline enables the pre_enable_prev_first flag. Example: - Panel - Bridge 1 - Bridge 2 pre_enable_prev_first - Bridge 3 - Bridge 4 pre_enable_prev_first - Bridge 5 pre_enable_prev_first - Bridge 6 - Encoder In this example Bridge 5 and Bridge 4 have pre_enable_prev_first. The logic looks for a bridge which enabled pre_enable_prev_first flags on each iteration and assigned the previou bridge to next and next to limit pointer if the bridge does enable pre_enable_prev_first flag. If control starts from Bridge 6 then it found next Bridge 5 is pre_enable_prev_first and immediately the next assigned to previous Bridge 6 and limit assignments to next Bridge 6 and call post_enable of Bridge 6 even though the next consecutive Bridge 5 is enabled with pre_enable_prev_first. This clearly misses the logic to find the state of next conducive bridge as everytime the next and limit assigns previous bridge if given bridge enabled pre_enable_prev_first. So, the resulting post_disable bridge order would be, - Encoder, Bridge 6, Bridge 5, Bridge 4, Bridge 3, Bridge 2, Bridge 1, Panel. This patch fixes this by assigning next with previou bridge only if the bridge doesn't enable pre_enable_prev_first flag and the next further assign it to limit. This way we can find the bridge that NOT requested prev to disable last. So, the resulting pre_enable bridge order with fix would be, - Encoder, Bridge 4, Bridge 5, Bridge 6, Bridge 2, Bridge 3, Bridge 1, Panel.

[ Upstream commit 01c0cce ] Commit 95da53d ("drm/omapdrm: Use regular fbdev I/O helpers") stopped console from updating for command mode displays because there is no damage handling in fb_sys_write() unlike we had earlier in drm_fb_helper_sys_write(). Let's fix the issue by adding FB_GEN_DEFAULT_DEFERRED_DMAMEM_OPS and FB_DMAMEM_HELPERS_DEFERRED as suggested by Thomas. We cannot use the FB_DEFAULT_DEFERRED_OPS as fb_deferred_io_mmap() won't work properly for write-combine.

printk: Let no_printk() use _printk()
[ Upstream commit 8522f6b ] When printk-indexing is enabled, each printk() invocation emits a pi_entry structure, containing the format string and other information related to its location in the kernel sources. This is even true for no_printk(): while the actual code to print the message is optimized out by the compiler due to the always-false check, the pi_entry structure is still emitted. As the main purpose of no_printk() is to provide a helper to maintain printf()-style format checking when debugging is disabled, this leads to the inclusion in the index of lots of printk formats that cannot be emitted by the current kernel. Fix this by switching no_printk() from printk() to _printk(). This reduces the size of an arm64 defconfig kernel with CONFIG_PRINTK_INDEX=y by 576 KiB.

dev_printk: Add and use dev_no_printk()
[ Upstream commit c26ec79 ] When printk-indexing is enabled, each dev_printk() invocation emits a pi_entry structure. This is even true when the dev_printk() is protected by an always-false check, as is typically the case for debug messages: while the actual code to print the message is optimized out by the compiler, the pi_entry structure is still emitted. Avoid emitting pi_entry structures for unavailable dev_printk() kernel messages by: 1. Introducing a dev_no_printk() helper, mimicked after the existing no_printk() helper, which calls _dev_printk() instead of dev_printk(), 2. Replacing all "if (0) dev_printk(...)" constructs by calls to the new helper. This reduces the size of an arm64 defconfig kernel with CONFIG_PRINTK_INDEX=y by 957 KiB.

drm/lcdif: Do not disable clocks on already suspended hardware
[ Upstream commit 172695f ] In case the LCDIF is enabled in DT but unused, the clocks used by the LCDIF are not enabled. Those clocks may even have a use count of 0 in case there are no other users of those clocks. This can happen e.g. in case the LCDIF drives HDMI bridge which has no panel plugged into the HDMI connector. Do not attempt to disable clocks in the suspend callback and re-enable clocks in the resume callback unless the LCDIF is enabled and was in use before the system entered suspend, otherwise the driver might end up trying to disable clocks which are already disabled with use count 0, and would trigger a warning from clock core about this condition. Note that the lcdif_rpm_suspend() and lcdif_rpm_resume() functions internally perform the clocks disable and enable operations and act as runtime PM hooks too.

drm/mediatek: Init
ddp_comp
with devm_kcalloc()[ Upstream commit 01a2c51 ] In the case where `conn_routes` is true we allocate an extra slot in the `ddp_comp` array but mtk_drm_crtc_create() never seemed to initialize it in the test case I ran. For me, this caused a later crash when we looped through the array in mtk_drm_crtc_mode_valid(). This showed up for me when I booted with `slub_debug=FZPUA` which poisons the memory initially. Without `slub_debug` I couldn't reproduce, presumably because the later code handles the value being NULL and in most cases (not guaranteed in all cases) the memory the allocator returned started out as 0. It really doesn't hurt to initialize the array with devm_kcalloc() since the array is small and the overhead of initting a handful of elements to 0 is small. In general initting memory to zero is a safer practice and usually it's suggested to only use the non-initting alloc functions if you really need to. Let's switch the function to use an allocation function that zeros the memory. For me, this avoids the crash.

ASoC: SOF: Intel: hda-dai: fix channel map configuration for aggregat…
…ed dailink [ Upstream commit 8310455 ] The existing code derives the channel map used to program the HDaudio link DMA from the hw_params, but that is not quite right in the case of aggregation. The code in soc-pcm.c splits the hw_params depending on the codec_ch_map, and we need to reconstruct the channel-map to insert the data in the right places. This issue is seen only on amplifier feedback capture where the data from the second amplifier was replaced by that of the first amplifier. Note that the loop iterator of the macro for_each_rtd_cpu_dais() is reused in a following loop. This is different to all existing usages of that macro, hence the use of a boolean flag to avoid an access to an uninitialized variable.

drm/msm/dp: Avoid a long timeout for AUX transfer if nothing connected
[ Upstream commit 5d1a749 ] As documented in the description of the transfer() function of "struct drm_dp_aux", the transfer() function can be called at any time regardless of the state of the DP port. Specifically if the kernel has the DP AUX character device enabled and userspace accesses "/dev/drm_dp_auxN" directly then the AUX transfer function will be called regardless of whether a DP device is connected. For eDP panels we have a special rule where we wait (with a 5 second timeout) for HPD to go high. This rule was important before all panels drivers were converted to call wait_hpd_asserted() and actually can be removed in a future commit. For external DP devices we never checked for HPD. That means that trying to access the DP AUX character device (AKA `hexdump -C /dev/drm_dp_auxN`) would very, very slowly timeout. Specifically on my system: $ time hexdump -C /dev/drm_dp_aux0 hexdump: /dev/drm_dp_aux0: Connection timed out real 0m8.200s We want access to the drm_dp_auxN character device to fail faster than 8 seconds when no DP cable is plugged in. Let's add a test to make transfers fail right away if a device isn't plugged in. Rather than testing the HPD line directly, we have the dp_display module tell us when AUX transfers should be enabled so we can handle cases where HPD is signaled out of band like with Type C.

media: atomisp: ssh_css: Fix a null-pointer dereference in load_video…
…_binaries [ Upstream commit 3b621e9 ] The allocation failure of mycs->yuv_scaler_binary in load_video_binaries() is followed with a dereference of mycs->yuv_scaler_binary after the following call chain: sh_css_pipe_load_binaries() |-> load_video_binaries(mycs->yuv_scaler_binary == NULL) | |-> sh_css_pipe_unload_binaries() |-> unload_video_binaries() In unload_video_binaries(), it calls to ia_css_binary_unload with argument &pipe->pipe_settings.video.yuv_scaler_binary[i], which refers to the same memory slot as mycs->yuv_scaler_binary. Thus, a null-pointer dereference is triggered.

media: uvcvideo: Add quirk for Logitech Rally Bar
[ Upstream commit 0773105 ] Logitech Rally Bar devices, despite behaving as UVC cameras, have a different power management system that the other cameras from Logitech. USB_QUIRK_RESET_RESUME is applied to all the UVC cameras from Logitech at the usb core. Unfortunately, USB_QUIRK_RESET_RESUME causes undesired USB disconnects in the Rally Bar that make them completely unusable. There is an open discussion about if we should fix this in the core or add a quirk in the UVC driver. In order to enable this hardware, let's land this patch first, and we can revert it later if there is a different conclusion.

drm/edid: Parse topology block for all DispID structure v1.x
[ Upstream commit e0a200a ] DisplayID spec v1.3 revision history notes do claim that the toplogy block was added in v1.3 so requiring structure v1.2 would seem correct, but there is at least one EDID in edid.tv with a topology block and structure v1.0. And there are also EDIDs with DisplayID structure v1.3 which seems to be totally incorrect as DisplayID spec v1.3 lists structure v1.2 as the only legal value. Unfortunately I couldn't find copies of DisplayID spec v1.0-v1.2 anywhere (even on vesa.org), so I'll have to go on empirical evidence alone. We used to parse the topology block on all v1.x structures until the check for structure v2.0 was added. Let's go back to doing that as the evidence does suggest that there are DisplayIDs in the wild that would miss out on the topology stuff otherwise. Also toss out DISPLAY_ID_STRUCTURE_VER_12 entirely as it doesn't appear we can really use it for anything. I *think* we could technically skip all the structure version checks as the block tags shouldn't conflict between v2.0 and v1.x. But no harm in having a bit of extra sanity checks I guess. So far I'm not aware of any user reported regressions from overly strict check, but I do know that it broke igt/kms_tiled_display's fake DisplayID as that one gets generated with structure v1.0.

clk: mediatek: pllfh: Don't log error for missing fhctl node
[ Upstream commit bb7b3c8 ] Support for fhctl clocks in apmixedsys was introduced at a later point and to this moment only one mt6795 based platform has a fhctl DT node present. Therefore the fhctl support in apmixedsys should be seen as optional and not cause an error when it is missing. Change the message's log level to warning. The warning level is chosen so that it will still alert the fact that fhctl support might be unintentionally missing, but without implying that this is necessarily an issue. Even if the FHCTL DT nodes are added to all current platforms moving forward, since those changes won't be backported, this ensures stable kernel releases won't have live with this error.

iommu: Undo pasid attachment only for the devices that have succeeded
[ Upstream commit b025dea ] There is no error handling now in __iommu_set_group_pasid(), it relies on its caller to loop all the devices to undo the pasid attachment. This is not self-contained and has drawbacks. It would result in unnecessary remove_dev_pasid() calls on the devices that have not been attached to the new domain. But the remove_dev_pasid() callback would get the new domain from the group->pasid_array. So for such devices, the iommu driver won't find the attachment under the domain, hence unable to do cleanup. This may not be a real problem today. But it depends on the implementation of the underlying iommu driver. e.g. the intel iommu driver would warn for such devices. Such warnings are unnecessary. To solve the above problem, it is necessary to handle the error within __iommu_set_group_pasid(). It only loops the devices that have attached to the new domain, and undo it.

clk: qcom: clk-alpha-pll: remove invalid Stromer register offset
[ Upstream commit 4f2bc4a ] The offset of the CONFIG_CTL_U register defined for the Stromer PLL is wrong. It is not aligned on a 4 bytes boundary which might causes errors in regmap operations. Maybe the intention behind of using the 0xff value was to indicate that the register is not implemented in the PLL, but this is not verified anywhere in the code. Moreover, this value is not used even in other register offset arrays despite that those PLLs also have unimplemented registers. Additionally, on the Stromer PLLs the current code only touches the CONFIG_CTL_U register if the result of pll_has_64bit_config() is true which condition is not affected by the change. Due to the reasons above, simply remove the CONFIG_CTL_U entry from the Stromer specific array.

clk: samsung: gs101: propagate PERIC0 USI SPI clock rate
[ Upstream commit 7b54d91 ] Introduce nMUX() for MUX clocks that can be reparented on clock rate change. "nMUX" comes from "n-to-1 selector", hopefully emphasising that the selector can change on clock rate changes. Ideally MUX/MUX_F() should change to not have the CLK_SET_RATE_NO_REPARENT flag set by default, and all their users to be updated to add the flag back (like in the case of DIV and GATE). But this is a very intrusive change and because for now only GS101 allows MUX reparenting on clock rate change, stick with nMUX(). GS101 defines MUX clocks that are dedicated for each instance of the IP. One example is USI IP (SPI, I2C, serial). The reparenting of these MUX clocks will not affect other instances of the same IP or different IPs altogether. When SPI transfer is being prepared, the spi-s3c64xx driver will call clk_set_rate() to change the rate of SPI source clock (IPCLK). But IPCLK is a gate (leaf) clock, so it must propagate the rate change up the clock tree, so that corresponding MUX/DIV clocks can actually change their values. Add CLK_SET_RATE_PARENT flag to corresponding clocks for all USI instances in GS101 PERIC0: USI{1-8, 14}. This change involves the following clocks: PERIC0 USI*: Clock Div range MUX Selection ------------------------------------------------------------------- gout_peric0_peric0_top0_ipclk_* - - dout_peric0_usi*_usi /1..16 - mout_peric0_usi*_usi_user - {24.5 MHz, 400 MHz} With input clock of 400 MHz this scheme provides the following IPCLK rate range, for each USI block: PERIC0 USI*: 1.5 MHz ... 400 MHz Accounting for internal /4 divider in SPI blocks, and because the max SPI frequency is limited at 50 MHz, it gives us next SPI SCK rates: PERIC0 USI_SPI*: 384 KHz ... 49.9 MHz Fixes: 893f133 ("clk: samsung: gs101: add support for cmu_peric0") Reviewed-by: Peter Griffin <peter.griffin@linaro.org> Acked-by: André Draszik <andre.draszik@linaro.org> Signed-off-by: Tudor Ambarus <tudor.ambarus@linaro.org> Link: https://lore.kernel.org/r/20240419100915.2168573-2-tudor.ambarus@linaro.org Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Signed-off-by: Sasha Levin <sashal@kernel.org>

Note that with this we allow the reparenting of the MUX_USIx clocks to OSCCLK. Each instance of the USI IP has its own MUX_USI clock, thus the reparenting of a MUX_USI clock corresponds to a single instance of the USI IP.

RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt
[ Upstream commit 2b23b60 ] In rxe_comp_queue_pkt() an incoming response packet skb is enqueued to the resp_pkts queue and then a decision is made whether to run the completer task inline or schedule it. Finally the skb is dereferenced to bump a 'hw' performance counter. This is wrong because if the completer task is already running in a separate thread it may have already processed the skb and freed it which can cause a seg fault. This has been observed infrequently in testing at high scale. This patch fixes this by changing the order of enqueuing the packet until after the counter is accessed.

RDMA/rxe: Fix incorrect rxe_put in error path
[ Upstream commit 8776618 ] In rxe_send() a ref is taken on the qp to keep it alive until the kfree_skb() has a chance to call the skb destructor rxe_skb_tx_dtor() which drops the reference. If the packet has an incorrect protocol the error path just calls kfree_skb() which will call the destructor which will drop the ref. Currently the driver also calls rxe_put() which is incorrect. Additionally since the packets sent to rxe_send() are under the control of the driver and it only ever produces IPV4 or IPV6 packets the simplest fix is to remove all the code in this block.

IB/mlx5: Use __iowrite64_copy() for write combining stores
[ Upstream commit ef30228 ] mlx5 has a built in self-test at driver startup to evaluate if the platform supports write combining to generate a 64 byte PCIe TLP or not. This has proven necessary because a lot of common scenarios end up with broken write combining (especially inside virtual machines) and there is other way to learn this information. This self test has been consistently failing on new ARM64 CPU designs (specifically with NVIDIA Grace's implementation of Neoverse V2). The C loop around writeq() generates some pretty terrible ARM64 assembly, but historically this has worked on a lot of existing ARM64 CPUs till now. We see it succeed about 1 time in 10,000 on the worst effected systems. The CPU architects speculate that the load instructions interspersed with the stores makes the WC buffers statistically flush too often and thus the generation of large TLPs becomes infrequent. This makes the boot up test unreliable in that it indicates no write-combining, however userspace would be fine since it uses a ST4 instruction. Further, S390 has similar issues where only the special zpci_memcpy_toio() will actually generate large TLPs, and the open coded loop does not trigger it at all. Fix both ARM64 and S390 by switching to __iowrite64_copy() which now provides architecture specific variants that have a high change of generating a large TLP with write combining. x86 continues to use a similar writeq loop in the generate __iowrite64_copy().

lib/test_hmm.c: handle src_pfns and dst_pfns allocation failure
[ Upstream commit c2af060 ] The kcalloc() in dmirror_device_evict_chunk() will return null if the physical memory has run out. As a result, if src_pfns or dst_pfns is dereferenced, the null pointer dereference bug will happen. Moreover, the device is going away. If the kcalloc() fails, the pages mapping a chunk could not be evicted. So add a __GFP_NOFAIL flag in kcalloc(). Finally, as there is no need to have physically contiguous memory, Switch kcalloc() to kvcalloc() in order to avoid failing allocations.

x86/insn: Fix PUSH instruction in x86 instruction decoder opcode map
[ Upstream commit 59162e0 ] The x86 instruction decoder is used not only for decoding kernel instructions. It is also used by perf uprobes (user space probes) and by perf tools Intel Processor Trace decoding. Consequently, it needs to support instructions executed by user space also. Opcode 0x68 PUSH instruction is currently defined as 64-bit operand size only i.e. (d64). That was based on Intel SDM Opcode Map. However that is contradicted by the Instruction Set Reference section for PUSH in the same manual. Remove 64-bit operand size only annotation from opcode 0x68 PUSH instruction.

ext4: avoid excessive credit estimate in ext4_tmpfile()

EXT4_MAXQUOTAS_INIT_BLOCKS() is 219, then 10 credits from ext4_tmpfile() itself and then ext4_xattr_credits_for_new_inode() adds more credits needed for security attributes and ACLs. Now the EXT4_MAXQUOTAS_INIT_BLOCKS() is in fact unnecessary because we've already initialized quotas with dquot_init() shortly before and so EXT4_MAXQUOTAS_TRANS_BLOCKS() is enough (which boils down to 3 credits).

drivers/virt/acrn: fix PFNMAP PTE checks in acrn_vm_ram_map()
[ Upstream commit 3d65860 ] Patch series "mm: follow_pte() improvements and acrn follow_pte() fixes". Patch #1 fixes a bunch of issues I spotted in the acrn driver. It compiles, that's all I know. I'll appreciate some review and testing from acrn folks. Patch #2+#3 improve follow_pte(), passing a VMA instead of the MM, adding more sanity checks, and improving the documentation. Gave it a quick test on x86-64 using VM_PAT that ends up using follow_pte(). This patch (of 3): We currently miss handling various cases, resulting in a dangerous follow_pte() (previously follow_pfn()) usage. (1) We're not checking PTE write permissions. Maybe we should simply always require pte_write() like we do for pin_user_pages_fast(FOLL_WRITE)? Hard to tell, so let's check for ACRN_MEM_ACCESS_WRITE for now. (2) We're not rejecting refcounted pages. As we are not using MMU notifiers, messing with refcounted pages is dangerous and can result in use-after-free. Let's make sure to reject them. (3) We are only looking at the first PTE of a bigger range. We only lookup a single PTE, but memmap->len may span a larger area.

iommu/vt-d: Decouple igfx_off from graphic identity mapping
[ Upstream commit ba00196 ] A kernel command called igfx_off was introduced in commit <ba39592764ed> ("Intel IOMMU: Intel IOMMU driver"). This command allows the user to disable the IOMMU dedicated to SOC-integrated graphic devices. Commit <9452618e7462> ("iommu/intel: disable DMAR for g4x integrated gfx") used this mechanism to disable the graphic-dedicated IOMMU for some problematic devices. Later, more problematic graphic devices were added to the list by commit <1f76249cc3beb> ("iommu/vt-d: Declare Broadwell igfx dmar support snafu"). On the other hand, commit <19943b0e30b05> ("intel-iommu: Unify hardware and software passthrough support") uses the identity domain for graphic devices if CONFIG_DMAR_BROKEN_GFX_WA is selected. + if (iommu_pass_through) + iommu_identity_mapping = 1; +#ifdef CONFIG_DMAR_BROKEN_GFX_WA + else + iommu_identity_mapping = 2; +#endif ... static int iommu_should_identity_map(struct pci_dev *pdev, int startup) { + if (iommu_identity_mapping == 2) + return IS_GFX_DEVICE(pdev); ... In the following driver evolution, CONFIG_DMAR_BROKEN_GFX_WA and quirk_iommu_igfx() are mixed together, causing confusion in the driver's device_def_domain_type callback. On one hand, dmar_map_gfx is used to turn off the graphic-dedicated IOMMU as a workaround for some buggy hardware; on the other hand, for those graphic devices, IDENTITY mapping is required for the IOMMU core. Commit <4b8d18c0c986> "iommu/vt-d: Remove INTEL_IOMMU_BROKEN_GFX_WA" has removed the CONFIG_DMAR_BROKEN_GFX_WA option, so the IDENTITY_DOMAIN requirement for graphic devices is no longer needed. Therefore, this requirement can be removed from device_def_domain_type() and igfx_off can be made independent.

iommu/amd: Enable Guest Translation after reading IOMMU feature register
[ Upstream commit de111f6 ] Commit 8e01797 ("iommu/amd: Enable Guest Translation before registering devices") moved IOMMU Guest Translation (GT) enablement to early init path. It does feature check based on Global EFR value (got from ACPI IVRS table). Later it adjusts EFR value based on IOMMU feature register (late_iommu_features_init()). It seems in some systems BIOS doesn't set gloabl EFR value properly. This is causing mismatch. Hence move IOMMU GT enablement after late_iommu_features_init() so that it does check based on IOMMU EFR value.

nfsd: don't create nfsv4recoverydir in nfsdfs when not used.
[ Upstream commit 0770249 ] When CONFIG_NFSD_LEGACY_CLIENT_TRACKING is not set, the virtual file /proc/fs/nfsd/nfsv4recoverydir is created but responds EINVAL to any access. This is not useful, is somewhat surprising, and it causes ltp to complain. The only known user of this file is in nfs-utils, which handles non-existence and read-failure equally well. So there is nothing to gain from leaving the file present but inaccessible. So this patch removes the file when its content is not available - i.e. when that config option is not selected. Also remove the #ifdef which hides some of the enum values when CONFIG_NFSD_V$ not selection. simple_fill_super() quietly ignores array entries that are not present, so having slots in the array that don't get used is perfectly acceptable. So there is no value in this #ifdef.

dax/bus.c: replace WARN_ON_ONCE() with lockdep asserts
[ Upstream commit c14c647 ] Patch series "dax/bus.c: Fixups for dax-bus locking", v3. Commit Fixes: c05ae9d ("dax/bus.c: replace driver-core lock usage by a local rwsem") introduced a few problems that this series aims to fix. Add back device_lock() where it was correctly used (during device manipulation operations), remove conditional locking in unregister_dax_dev() and unregister_dax_mapping(), use non-interruptible versions of rwsem locks when not called from a user process, and fix up a write vs. read usage of an rwsem. This patch (of 4): In [1], Dan points out that all of the WARN_ON_ONCE() usage in the referenced patch should be replaced with lockdep_assert_held, or lockdep_held_assert_write(). Replace these as appropriate.

dax/bus.c: fix locking for unregister_dax_dev / unregister_dax_mappin…
…g paths [ Upstream commit 6f6544f ] Commit c05ae9d ("dax/bus.c: replace driver-core lock usage by a local rwsem") aimed to undo device_lock() abuses for protecting changes to dax-driver internal data-structures like the dax_region resource tree to device-dax-instance range structures. However, the device_lock() was legitimately enforcing that devices to be deleted were not current actively attached to any driver nor assigned any capacity from the region. As a result of the device_lock restoration in delete_store(), the conditional locking in unregister_dev_dax() and unregister_dax_mapping() can be removed.

tracing/user_events: Fix non-spaced field matching
[ Upstream commit bd125a0 ] When the ABI was updated to prevent same name w/different args, it missed an important corner case when fields don't end with a space. Typically, space is used for fields to help separate them, like "u8 field1; u8 field2". If no spaces are used, like "u8 field1;u8 field2", then the parsing works for the first time. However, the match check fails on a subsequent register, leading to confusion. This is because the match check uses argv_split() and assumes that all fields will be split upon the space. When spaces are used, we get back { "u8", "field1;" }, without spaces we get back { "u8", "field1;u8" }. This causes a mismatch, and the user program gets back -EADDRINUSE. Add a method to detect this case before calling argv_split(). If found force a space after the field separator character ';'. This ensures all cases work properly for matching. With this fix, the following are all treated as matching: u8 field1;u8 field2 u8 field1; u8 field2 u8 field1;\tu8 field2 u8 field1;\nu8 field2 Link: https://lore.kernel.org/linux-trace-kernel/20240423162338.292-2-beaub@linux.microsoft.com Fixes: ba470ee ("tracing/user_events: Prevent same name but different args event") Signed-off-by: Beau Belgrave <beaub@linux.microsoft.com> Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> Signed-off-by: Sasha Levin <sashal@kernel.org>

net: qrtr: ns: Fix module refcnt
[ Upstream commit fd76e5c ] The qrtr protocol core logic and the qrtr nameservice are combined into a single module. Neither the core logic or nameservice provide much functionality by themselves; combining the two into a single module also prevents any possible issues that may stem from client modules loading inbetween qrtr and the ns. Creating a socket takes two references to the module that owns the socket protocol. Since the ns needs to create the control socket, this creates a scenario where there are always two references to the qrtr module. This prevents the execution of 'rmmod' for qrtr. To resolve this, forcefully put the module refcount for the socket opened by the nameservice.

sched/core: Fix incorrect initialization of the 'burst' parameter in …
…cpu_max_write() [ Upstream commit 49217ea ] In the cgroup v2 CPU subsystem, assuming we have a cgroup named 'test', and we set cpu.max and cpu.max.burst: # echo 1000000 > /sys/fs/cgroup/test/cpu.max # echo 1000000 > /sys/fs/cgroup/test/cpu.max.burst then we check cpu.max and cpu.max.burst: # cat /sys/fs/cgroup/test/cpu.max 1000000 100000 # cat /sys/fs/cgroup/test/cpu.max.burst 1000000 Next we set cpu.max again and check cpu.max and cpu.max.burst: # echo 2000000 > /sys/fs/cgroup/test/cpu.max # cat /sys/fs/cgroup/test/cpu.max 2000000 100000 # cat /sys/fs/cgroup/test/cpu.max.burst 1000 ... we find that the cpu.max.burst value changed unexpectedly. In cpu_max_write(), the unit of the burst value returned by tg_get_cfs_burst() is microseconds, while in cpu_max_write(), the burst unit used for calculation should be nanoseconds, which leads to the bug. To fix it, get the burst value directly from tg->cfs_bandwidth.burst.

l2tp: fix ICMP error handling for UDP-encap sockets
[ Upstream commit 6e828dc ] Since commit a36e185 ("udp: Handle ICMP errors for tunnels with same destination port on both endpoints") UDP's handling of ICMP errors has allowed for UDP-encap tunnels to determine socket associations in scenarios where the UDP hash lookup could not. Subsequently, commit d26796a ("udp: check udp sock encap_type in __udp_lib_err") subtly tweaked the approach such that UDP ICMP error handling would be skipped for any UDP socket which has encapsulation enabled. In the case of L2TP tunnel sockets using UDP-encap, this latter modification effectively broke ICMP error reporting for the L2TP control plane. To a degree this isn't catastrophic inasmuch as the L2TP control protocol defines a reliable transport on top of the underlying packet switching network which will eventually detect errors and time out. However, paying attention to the ICMP error reporting allows for more timely detection of errors in L2TP userspace, and aids in debugging connectivity issues. Reinstate ICMP error handling for UDP encap L2TP tunnels: * implement struct udp_tunnel_sock_cfg .encap_err_rcv in order to allow the L2TP code to handle ICMP errors; * only implement error-handling for tunnels which have a managed socket: unmanaged tunnels using a kernel socket have no userspace to report errors back to; * flag the error on the socket, which allows for userspace to get an error such as -ECONNREFUSED back from sendmsg/recvmsg; * pass the error into ip[v6]_icmp_error() which allows for userspace to get extended error information via.

ALSA: hda - Improve 3.5mm hotplug w/ROG strix B550
When plugging of unplugging an audio jack on this motherbaord, sometimes the audio jacks would stop appearing to pipewire/pulseaudio. Interestingly `cat`-ing out the file `/proc/asound/<card number>/codec#0`, and or restarting pipewire fixes the issue temporarily. This PR improves the current functionality by making hotplug with one 3.5mm jack work, it still breaks if hotplug is between multiple jacks though.
