2023-11-09cifs: handle cases where a channel is closedShyam Prasad N
So far, SMB multichannel could only scale up, but not scale down the number of channels. In this series of patch, we now allow the client to deal with the case of multichannel disabled on the server when the share is mounted. With that change, we now need the ability to scale down the channels. This change allows the client to deal with cases of missing channels more gracefully.

2023-11-09ALSA: hda: ASUS UM5302LA: Added quirks for cs35L41/10431A83 on i2c busVitalii Torshyn
Proposed patch fixes initialization of CSC3551 on the UM5302LA laptop. Patching DSDT table is not required since ASUS did added _DSD entry. Nothing new introduced but reused work started by Stefan B. Currently there is no official firmware available for 10431A83 on cirrus git unfortunately. For testing used 104317f3 (which is also seems on i2c bus): $ cd /lib/firmware/cirrus/ && \ for fw in $(find ./ -name '*104317f3*'); do newfw=$(echo $fw | sed 's/104317f3/10431a83/g'); echo echo "$fw -> $newfw"; ln -s $f $newfw; done With the patch applied to 6.6.0 and obviously symlinks to 104317F3 FW, speakers works and to my susrprise they sound quite good and loud without distortion. Probably confirmation from cirrus team is needed on firmware.

2023-11-09ALSA: info: Fix potential deadlock at disconnectionTakashi Iwai
As reported recently, ALSA core info helper may cause a deadlock at the forced device disconnection during the procfs operation. The proc_remove() (that is called from the snd_card_disconnect() helper) has a synchronization of the pending procfs accesses via wait_for_completion(). Meanwhile, ALSA procfs helper takes the global mutex_lock(&info_mutex) at both the proc_open callback and snd_card_info_disconnect() helper. Since the proc_open can't finish due to the mutex lock, wait_for_completion() never returns, either, hence it deadlocks. TASK#1 TASK#2 proc_reg_open() takes use_pde() snd_info_text_entry_open() snd_card_disconnect() snd_info_card_disconnect() takes mutex_lock(&info_mutex) proc_remove() wait_for_completion(unused_pde) ... waiting task#1 closes mutex_lock(&info_mutex) => DEADLOCK This patch is a workaround for avoiding the deadlock scenario above. The basic strategy is to move proc_remove() call outside the mutex lock. proc_remove() can work gracefully without extra locking, and it can delete the tree recursively alone. So, we call proc_remove() at snd_info_card_disconnection() at first, then delete the rest resources recursively within the info_mutex lock. After the change, the function snd_info_disconnect() doesn't do disconnection by itself any longer, but it merely clears the procfs pointer. So rename the function to snd_info_clear_entries() for avoiding confusion. The similar change is applied to snd_info_free_entry(), too. Since the proc_remove() is called only conditionally with the non-NULL entry->p, it's skipped after the snd_info_clear_entries() call.

2023-11-09x86/acpi: Ignore invalid x2APIC entriesZhang Rui
Currently, the kernel enumerates the possible CPUs by parsing both ACPI MADT Local APIC entries and x2APIC entries. So CPUs with "valid" APIC IDs, even if they have duplicated APIC IDs in Local APIC and x2APIC, are always enumerated. Below is what ACPI MADT Local APIC and x2APIC describes on an Ivebridge-EP system, [02Ch 0044 1] Subtable Type : 00 [Processor Local APIC] [02Fh 0047 1] Local Apic ID : 00 ... [164h 0356 1] Subtable Type : 00 [Processor Local APIC] [167h 0359 1] Local Apic ID : 39 [16Ch 0364 1] Subtable Type : 00 [Processor Local APIC] [16Fh 0367 1] Local Apic ID : FF ... [3ECh 1004 1] Subtable Type : 09 [Processor Local x2APIC] [3F0h 1008 4] Processor x2Apic ID : 00000000 ... [B5Ch 2908 1] Subtable Type : 09 [Processor Local x2APIC] [B60h 2912 4] Processor x2Apic ID : 00000077 As a result, kernel shows "smpboot: Allowing 168 CPUs, 120 hotplug CPUs". And this wastes significant amount of memory for the per-cpu data. Plus this also breaks https://lore.kernel.org/all/87edm36qqb.ffs@tglx/, because __max_logical_packages is over-estimated by the APIC IDs in the x2APIC entries. According to https://uefi.org/specs/ACPI/6.5/05_ACPI_Software_Programming_Model.html#processor-local-x2apic-structure: "[Compatibility note] On some legacy OSes, Logical processors with APIC ID values less than 255 (whether in XAPIC or X2APIC mode) must use the Processor Local APIC structure to convey their APIC information to OSPM, and those processors must be declared in the DSDT using the Processor() keyword. Logical processors with APIC ID values 255 and greater must use the Processor Local x2APIC structure and be declared using the Device() keyword." Therefore prevent the registration of x2APIC entries with an APIC ID less than 255 if the local APIC table enumerates valid APIC IDs.

2023-11-09btrfs: make OWNER_REF_KEY type value smallest among inline refsBoris Burkov
BTRFS_EXTENT_OWNER_REF_KEY is the type of simple quotas extent owner refs. This special inline ref goes in front of all other inline refs. In general, inline refs have a required sorted order s.t. type never decreases (among other requirements). This was recently reified into a tree-checker and fsck rule, which broke simple quotas. To be fair, though, in a sense, the new owner ref item had also violated that not yet fully enforced requirement. This fix brings the owner ref item into compliance with the requirement that inline ref type never decrease. btrfs/301 exercises this behavior and should pass again with this fix.

2023-11-09btrfs: fix qgroup record leaks when using simple quotasFilipe Manana
When using simple quotas we are not supposed to allocate qgroup records when adding delayed references. However we allocate them if either mode of quotas is enabled (the new simple one or the old one), but then we never free them because running the accounting, which frees the records, is only run when using the old quotas (at btrfs_qgroup_account_extents()), resulting in a memory leak of the records allocated when adding delayed references. Fix this by allocating the records only if the old quotas mode is enabled. Also fix btrfs_qgroup_trace_extent_nolock() to return 1 if the old quotas mode is not enabled - meaning the caller has to free the record.

2023-11-09btrfs: fix race between accounting qgroup extents and removing a qgroupFilipe Manana
When doing qgroup accounting for an extent, we take the spinlock fs_info->qgroup_lock and then add qgroups to the local list (iterator) named "qgroups". These qgroups are found in the fs_info->qgroup_tree rbtree. After we're done, we unlock fs_info->qgroup_lock and then call qgroup_iterator_nested_clean(), which will iterate over all the qgroups added to the local list "qgroups" and then delete them from the list. Deleting a qgroup from the list can however result in a use-after-free if a qgroup remove operation happens after we unlock fs_info->qgroup_lock and before or while we are at qgroup_iterator_nested_clean(). Fix this by calling qgroup_iterator_nested_clean() while still holding the lock fs_info->qgroup_lock - we don't need it under the 'out' label since before taking the lock the "qgroups" list is always empty. This guarantees safety because btrfs_remove_qgroup() takes that lock before removing a qgroup from the rbtree fs_info->qgroup_tree.

2023-11-08scsi: sd: Fix sshdr use in sd_suspend_common()Mike Christie
If scsi_execute_cmd() returns < 0, it doesn't initialize the sshdr, so we shouldn't access the sshdr. If it returns 0, then the cmd executed successfully, so there is no need to check the sshdr. sd_sync_cache() will only access the sshdr if it's been setup because it calls scsi_status_is_check_condition() before accessing it. However, the sd_sync_cache() caller, sd_suspend_common(), does not check. sd_suspend_common() is only checking for ILLEGAL_REQUEST which it's using to determine if the command is supported. If it's not it just ignores the error. So to fix its sshdr use this patch just moves that check to sd_sync_cache() where it converts ILLEGAL_REQUEST to success/0. sd_suspend_common() was ignoring that error and sd_shutdown() doesn't check for errors so there will be no behavior changes.

Smatch complains that "dentry" is never initialized. These days everyone initializes all their stack variables to zero so this means that it will trigger a warning every time this function is run. Really, debugfs functions are not supposed to be checked for errors in normal code. For example, if we updated this code to check the correct variable then it would print a warning if CONFIG_DEBUGFS was disabled. We don't want that. Just delete the check.

2023-11-08net/sched: act_ct: Always fill offloading tuple iifidxVlad Buslov
Referenced commit doesn't always set iifidx when offloading the flow to hardware. Fix the following cases: - nf_conn_act_ct_ext_fill() is called before extension is created with nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with unspecified iifidx when connection is offloaded after only single original-direction packet has been processed by tc data path. Always fill the new nf_conn_act_ct_ext instance after creating it in nf_conn_act_ct_ext_add(). - Offloading of unidirectional UDP NEW connections is now supported, but ct flow iifidx field is not updated when connection is promoted to bidirectional which can result reply-direction iifidx to be zero when refreshing the connection. Fill in the extension and update flow iifidx before calling flow_offload_refresh().

The randstruct GCC plugin tried to discover "fake" flexible arrays to issue warnings about them in randomized structs. In the future LSM overhead reduction series, it would be legal to have a randomized struct with a 1-element array, and this should _not_ be treated as a flexible array, especially since commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3"). Disable the 0-sized and 1-element array discovery logic in the plugin, but keep the "true" flexible array check.

2023-11-08x86/shstk: Delay signal entry SSP write until after user accessesRick Edgecombe
When a signal is being delivered, the kernel needs to make accesses to userspace. These accesses could encounter an access error, in which case the signal delivery itself will trigger a segfault. Usually this would result in the kernel killing the process. But in the case of a SEGV signal handler being configured, the failure of the first signal delivery will result in *another* signal getting delivered. The second signal may succeed if another thread has resolved the issue that triggered the segfault (i.e. a well timed mprotect()/mmap()), or the second signal is being delivered to another stack (i.e. an alt stack). On x86, in the non-shadow stack case, all the accesses to userspace are done before changes to the registers (in pt_regs). The operation is aborted when an access error occurs, so although there may be writes done for the first signal, control flow changes for the signal (regs->ip, regs->sp, etc) are not committed until all the accesses have already completed successfully. This means that the second signal will be delivered as if it happened at the time of the first signal. It will effectively replace the first aborted signal, overwriting the half-written frame of the aborted signal. So on sigreturn from the second signal, control flow will resume happily from the point of control flow where the original signal was delivered. The problem is, when shadow stack is active, the shadow stack SSP register/MSR is updated *before* some of the userspace accesses. This means if the earlier accesses succeed and the later ones fail, the second signal will not be delivered at the same spot on the shadow stack as the first one. So on sigreturn from the second signal, the SSP will be pointing to the wrong location on the shadow stack (off by a frame). Pengfei privately reported that while using a shadow stack enabled glibc, the “signal06” test in the LTP test-suite hung. It turns out it is testing the above described double signal scenario. When this test was compiled with shadow stack, the first signal pushed a shadow stack sigframe, then the second pushed another. When the second signal was handled, the SSP was at the first shadow stack signal frame instead of the original location. The test then got stuck as the #CP from the twice incremented SSP was incorrect and generated segfaults in a loop. Fix this by adjusting the SSP register only after any userspace accesses, such that there can be no failures after the SSP is adjusted. Do this by moving the shadow stack sigframe push logic to happen after all other userspace accesses. Note, sigreturn (as opposed to the signal delivery dealt with in this patch) has ordering behavior that could lead to similar failures. The ordering issues there extend beyond shadow stack to include the alt stack restoration. Fixing that would require cross-arch changes, and the ordering today does not cause any known test or apps breakages. So leave it as is, for now.

The keyring and auth functions can be called from both the host and the target side and are controlled by Kconfig options for each of the combinations, but the declarations are controlled by #ifdef checks on the shared Kconfig symbols. This leads to link failures in combinations where one of the frontends is built-in and the other one is a module, and the keyring code ends up in a module that is not reachable from the builtin code: ld: drivers/nvme/host/core.o: in function `nvme_core_exit': core.c:(.exit.text+0x4): undefined reference to `nvme_keyring_exit' ld: drivers/nvme/host/core.o: in function `nvme_core_init': core.c:(.init.text+0x94): undefined reference to `nvme_keyring_init ld: drivers/nvme/host/tcp.o: in function `nvme_tcp_setup_ctrl': tcp.c:(.text+0x4c18): undefined reference to `nvme_tls_psk_default' Address this by moving nvme_keyring_init()/nvme_keyring_exit() into module init/exit functions for the keyring module.
