2025-11-10ASoC: cs35l56: Alter error codes for calibration routineRichard Fitzgerald
Adjust the error codes returned by the calibration debugfs files to provide a wider range of errors and make them more consistent. There is a limited number of standard errors and it's not always easy to find an error code that accurately describes what happened. Additionally, user code often uses strerror() or something similar to report a generic error description. The original calibration code used a limited set of errors to attempt to avoid user error strings that would be confusing or unclear on a file read/write. However, this restricts the ability to provide informative errors. This limited error range didn't help very much with debugging so it has been expanded, rather than worrying about what strerror() would return. The errors are now more consistent: ENXIO Calibration is not supported by the driver. EOPNOTSUPP The given calibration command is not supported. EBUSY Cannot calibrate because the amp is playing audio. ERANGE Calibration result was out-of-range. ETIMEDOUT Calibration did not complete. EMSGSIZE Blob written to cal_data is the wrong size. ENODATA No calibration data available to read from cal_data, or Blob written to cal_data does not contain calibration, or No calibration data available to save to UEFI. EIO General failure to communicate with the firmware, mainly indicating that firmware controls are missing. EINVAL Has its normal meaning that an invalid argument was passed.

2025-11-10ns: add asserts for active refcount underflowChristian Brauner

2025-11-10ns: handle setns(pidfd, ...) cleanlyChristian Brauner
The setns() system call supports: (1) namespace file descriptors (nsfd) (2) process file descriptors (pidfd) When using nsfds the namespaces will remain active because they are pinned by the vfs. However, when pidfds are used things are more complicated. When the target task exits and passes through exit_nsproxy_namespaces() or is reaped and thus also passes through exit_cred_namespaces() after the setns()'ing task has called prepare_nsset() but before the active reference count of the set of namespaces it wants to setns() to might have been dropped already: P1 P2 pid_p1 = clone(CLONE_NEWUSER | CLONE_NEWNET | CLONE_NEWNS) pidfd = pidfd_open(pid_p1) setns(pidfd, CLONE_NEWUSER | CLONE_NEWNET | CLONE_NEWNS) prepare_nsset() exit(0) // ns->__ns_active_ref == 1 // parent_ns->__ns_active_ref == 1 -> exit_nsproxy_namespaces() -> exit_cred_namespaces() // ns_active_ref_put() will also put // the reference on the owner of the // namespace. If the only reason the // owning namespace was alive was // because it was a parent of @ns // it's active reference count now goes // to zero... -------------------------------- // | // ns->__ns_active_ref == 0 | // parent_ns->__ns_active_ref == 0 | | commit_nsset() -----------------> // If setns() // now manages to install the namespaces // it will call ns_active_ref_get() // on them thus bumping the active reference // count from zero again but without also // taking the required reference on the owner. // Thus we get: // // ns->__ns_active_ref == 1 // parent_ns->__ns_active_ref == 0 When later someone does ns_active_ref_put() on @ns it will underflow parent_ns->__ns_active_ref leading to a splat from our asserts thinking there are still active references when in fact the counter just underflowed. So resurrect the ownership chain if necessary as well. If the caller succeeded to grab passive references to the set of namespaces the setns() should simply succeed even if the target task exists or gets reaped in the meantime and thus has dropped all active references to its namespaces. The race is rare and can only be triggered when using pidfs to setns() to namespaces. Also note that active reference on initial namespaces are nops. Since we now always handle parent references directly we can drop ns_ref_active_get_owner() when adding a namespace to a namespace tree. This is now all handled uniformly in the places where the new namespaces actually become active.

2025-11-09kho: allocate metadata directly from the buddy allocatorPasha Tatashin
KHO allocates metadata for its preserved memory map using the slab allocator via kzalloc(). This metadata is temporary and is used by the next kernel during early boot to find preserved memory. A problem arises when KFENCE is enabled. kzalloc() calls can be randomly intercepted by kfence_alloc(), which services the allocation from a dedicated KFENCE memory pool. This pool is allocated early in boot via memblock. When booting via KHO, the memblock allocator is restricted to a "scratch area", forcing the KFENCE pool to be allocated within it. This creates a conflict, as the scratch area is expected to be ephemeral and overwriteable by a subsequent kexec. If KHO metadata is placed in this KFENCE pool, it leads to memory corruption when the next kernel is loaded. To fix this, modify KHO to allocate its metadata directly from the buddy allocator instead of slab.

2025-11-09mm/huge_memory: do not change split_huge_page*() target order silentlyZi Yan
Page cache folios from a file system that support large block size (LBS) can have minimal folio order greater than 0, thus a high order folio might not be able to be split down to order-0. Commit e220917fa507 ("mm: split a folio in minimum folio order chunks") bumps the target order of split_huge_page*() to the minimum allowed order when splitting a LBS folio. This causes confusion for some split_huge_page*() callers like memory failure handling code, since they expect after-split folios all have order-0 when split succeeds but in reality get min_order_for_split() order folios and give warnings. Fix it by failing a split if the folio cannot be split to the target order. Rename try_folio_split() to try_folio_split_to_order() to reflect the added new_order parameter. Remove its unused list parameter. [The test poisons LBS folios, which cannot be split to order-0 folios, and also tries to poison all memory. The non split LBS folios take more memory than the test anticipated, leading to OOM. The patch fixed the kernel warning and the test needs some change to avoid OOM.] Link: https://lkml.kernel.org/r/20251017013630.139907-1-ziy@nvidia.com Fixes: e220917fa507 ("mm: split a folio in minimum folio order chunks") Signed-off-by: Zi Yan <ziy@nvidia.com> Reported-by: syzbot+e6367ea2fdab6ed46056@syzkaller.appspotmail.com Closes: https://lore.kernel.org/all/68d2c943.a70a0220.1b52b.02b3.GAE@google.com/ Reviewed-by: Luis Chamberlain <mcgrof@kernel.org> Reviewed-by: Pankaj Raghav <p.raghav@samsung.com> Reviewed-by: Wei Yang <richard.weiyang@gmail.com> Acked-by: David Hildenbrand <david@redhat.com> Reviewed-by: Lorenzo Stoakes <lorenzo.stoakes@oracle.com> Reviewed-by: Miaohe Lin <linmiaohe@huawei.com> Cc: Baolin Wang <baolin.wang@linux.alibaba.com> Cc: Barry Song <baohua@kernel.org> Cc: David Hildenbrand <david@redhat.com> Cc: Dev Jain <dev.jain@arm.com> Cc: Jane Chu <jane.chu@oracle.com> Cc: Lance Yang <lance.yang@linux.dev> Cc: Liam Howlett <liam.howlett@oracle.com> Cc: Mariano Pache <npache@redhat.com> Cc: Matthew Wilcox (Oracle) <willy@infradead.org> Cc: Naoya Horiguchi <nao.horiguchi@gmail.com> Cc: Ryan Roberts <ryan.roberts@arm.com> Cc: Christian Brauner <brauner@kernel.org> Cc: <stable@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>

2025-11-08Merge patch series "Support power resources defined in acpi on ata"Martin K. Petersen
Markus Probst <markus.probst@posteo.de> says: This series adds support for power resources defined in acpi on ata ports/devices. A device can define a power resource in an ata port/device, which then gets powered on right before the port is probed. This can be useful for devices, which have sata power connectors that are: a: powered down by default b: can be individually powered on like in some synology nas devices. If thats the case it will be assumed, that the power resource won't survive reboots and therefore the disk will be stopped.

2025-11-08scsi: sd: Add manage_restart device attribute to scsi_diskMarkus Probst
In addition to the already existing manage_shutdown, manage_system_start_stop and manage_runtime_start_stop device scsi_disk attributes, add manage_restart, which allows the high-level device driver (sd) to manage the device power state for SYSTEM_RESTART if set to 1. This attribute is necessary for the following commit "ata: stop disk on restart if ACPI power resources are found" to avoid a potential disk power failure in the case the SATA power connector does not retain the power state after a restart.

2025-11-07tcp: add net.ipv4.tcp_comp_sack_rtt_percentEric Dumazet
TCP SACK compression has been added in 2018 in commit 5d9f4262b7ea ("tcp: add SACK compression"). It is working great for WAN flows (with large RTT). Wifi in particular gets a significant boost _when_ ACK are suppressed. Add a new sysctl so that we can tune the very conservative 5 % value that has been used so far in this formula, so that small RTT flows can benefit from this feature. delay = min ( 5 % of RTT, 1 ms) This patch adds new tcp_comp_sack_rtt_percent sysctl to ease experiments and tuning. Given that we cap the delay to 1ms (tcp_comp_sack_delay_ns sysctl), set the default value to 33 %. Quoting Neal Cardwell ( https://lore.kernel.org/netdev/CADVnQymZ1tFnEA1Q=vtECs0=Db7zHQ8=+WCQtnhHFVbEOzjVnQ@mail.gmail.com/ ) The rationale for 33% is basically to try to facilitate pipelining, where there are always at least 3 ACKs and 3 GSO/TSO skbs per SRTT, so that the path can maintain a budget for 3 full-sized GSO/TSO skbs "in flight" at all times: + 1 skb in the qdisc waiting to be sent by the NIC next + 1 skb being sent by the NIC (being serialized by the NIC out onto the wire) + 1 skb being received and aggregated by the receiver machine's aggregation mechanism (some combination of LRO, GRO, and sack compression) Note that this is basically the same magic number (3) and the same rationales as: (a) tcp_tso_should_defer() ensuring that we defer sending data for no longer than cwnd/tcp_tso_win_divisor (where tcp_tso_win_divisor = 3), and (b) bbr_quantization_budget() ensuring that cwnd is at least 3 GSO/TSO skbs to maintain pipelining and full throughput at low RTTs Signed-off-by: Eric Dumazet <edumazet@google.com> Reviewed-by: Neal Cardwell <ncardwell@google.com> Link: https://patch.msgid.link/20251106115236.3450026-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Since commit 54a378f43425 ("tcp: add the ability to control max RTO"), TFO SYN+ACK RTO is capped by the TFO full sk's inet_csk(sk)->icsk_rto_max. The value is inherited from the parent listener. Let's apply the same cap to non-TFO SYN+ACK. Note that req->rsk_listener is always non-NULL when we call tcp_reqsk_timeout() in reqsk_timer_handler() or tcp_check_req(). It could be NULL for SYN cookie req, but we do not use req->timeout then.
