kbuild: Split .modinfo out from ELF_DETAILS

2026-03-12T11:09:44+00:00

commit 8678591b47469fe16357234efef9b260317b8be4 upstream. Commit 3e86e4d74c04 ("kbuild: keep .modinfo section in vmlinux.unstripped") added .modinfo to ELF_DETAILS while removing it from COMMON_DISCARDS, as it was needed in vmlinux.unstripped and ELF_DETAILS was present in all architecture specific vmlinux linker scripts. While this shuffle is fine for vmlinux, ELF_DETAILS and COMMON_DISCARDS may be used by other linker scripts, such as the s390 and x86 compressed boot images, which may not expect to have a .modinfo section. In certain circumstances, this could result in a bootloader failing to load the compressed kernel [1]. Commit ddc6cbef3ef1 ("s390/boot/vmlinux.lds.S: Ensure bzImage ends with SecureBoot trailer") recently addressed this for the s390 bzImage but the same bug remains for arm, parisc, and x86. The presence of .modinfo in the x86 bzImage was the root cause of the issue worked around with commit d50f21091358 ("kbuild: align modinfo section for Secureboot Authenticode EDK2 compat"). misc.c in arch/x86/boot/compressed includes lib/decompress_unzstd.c, which in turn includes lib/xxhash.c and its MODULE_LICENSE / MODULE_DESCRIPTION macros due to the STATIC definition. Split .modinfo out from ELF_DETAILS into its own macro and handle it in all vmlinux linker scripts. Discard .modinfo in the places where it was previously being discarded from being in COMMON_DISCARDS, as it has never been necessary in those uses.

m68k: nommu: fix memmove() with differently aligned src and dest for 68000

2026-03-04T12:20:31+00:00

[ Upstream commit 590fe2f46c8698bb758f9002cb247ca10ce95569 ] 68000 has different alignment needs to 68020+. memcpy() checks if the destination is aligned and does a smaller copy to fix the alignment and then critically for 68000 it checks if the source is still unaligned and if it is reverts to smaller copies. memmove() does not currently do the second part and malfunctions if one of the pointers is aligned and the other isn't. This is apparently getting triggered by printk. If I put breakpoints into the new checks added by this commit the first hit looks like this: memmove (n=205, src=0x2f3971 , dest=0x2f3980 ) at arch/m68k/lib/memmove.c:82 Signed-off-by: Daniel Palmer Signed-off-by: Greg Ungerer Signed-off-by: Sasha Levin

Use CONFIG_EXT4_FS instead of CONFIG_EXT3_FS in all of the defconfigs

2025-10-14T01:50:40+00:00

Commit d6ace46c82fd ("ext4: remove obsolete EXT3 config options") removed the obsolete EXT3_CONFIG options, since it had been over a decade since fs/ext3 had been removed. Unfortunately, there were a number of defconfigs that still used CONFIG_EXT3_FS which the cleanup commit didn't fix up. This led to a large number of defconfig test builds to fail. Oops.

Pull pci updates from Bjorn Helgaas: "Enumeration: - Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that take config space accessor functions. Implement pci_find_capability(), pci_find_ext_capability(), and dwc, dwc endpoint, and cadence capability search interfaces with them (Hans Zhang) - Leave parent unit address 0 in 'interrupt-map' so that when we build devicetree nodes to describe PCI functions that contain multiple peripherals, we can build this property even when interrupt controllers lack 'reg' properties (Lorenzo Pieralisi) - Add a Xeon 6 quirk to disable Extended Tags and limit Max Read Request Size to 128B to avoid a performance issue (Ilpo Järvinen) - Add sysfs 'serial_number' file to expose the Device Serial Number (Matthew Wood) - Fix pci_acpi_preserve_config() memory leak (Nirmoy Das) Resource management: - Align m68k pcibios_enable_device() with other arches (Ilpo Järvinen) - Remove sparc pcibios_enable_device() implementations that don't do anything beyond what pci_enable_resources() does (Ilpo Järvinen) - Remove mips pcibios_enable_resources() and use pci_enable_resources() instead (Ilpo Järvinen) - Clean up bridge window sizing and assignment (Ilpo Järvinen), including: - Leave non-claimed bridge windows disabled - Enable bridges even if a window wasn't assigned because not all windows are required by downstream devices - Preserve bridge window type when releasing the resource, since the type is needed for reassignment - Consolidate selection of bridge windows into two new interfaces, pbus_select_window() and pbus_select_window_for_type(), so this is done consistently - Compute bridge window start and end earlier to avoid logging stale information MSI: - Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol Vives) Error handling: - Align AER with EEH by allowing drivers to request a Bus Reset on Non-Fatal Errors (in addition to the reset on Fatal Errors that we already do) (Lukas Wunner) - If error recovery fails, emit FAILED_RECOVERY uevents for the devices, not for the bridge leading to them. This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner) - Align AER with EEH by calling err_handler.error_detected() callbacks to notify drivers if error recovery fails (Lukas Wunner) - Align AER with EEH by restoring device error_state to pci_channel_io_normal before the err_handler.slot_reset() callback. This is earlier than before the err_handler.resume() callback (Lukas Wunner) - Emit a BEGIN_RECOVERY uevent when driver's err_handler.error_detected() requests a reset, as well as when it says recovery is complete or can be done without a reset (Niklas Schnelle) - Align s390 with AER and EEH by emitting uevents during error recovery (Niklas Schnelle) - Align EEH with AER and s390 by emitting BEGIN_RECOVERY, SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the result of err_handler.error_detected() (Niklas Schnelle) - Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES error information identifies a device without an AER Capability (Breno Leitao) - Update error decoding and TLP Log printing for new errors in current PCIe base spec (Lukas Wunner) - Update error recovery documentation to match the current code and use consistent nomenclature (Lukas Wunner) ASPM: - Enable all ClockPM and ASPM states for devicetree platforms, since there's typically no firmware that enables ASPM This is a risky change that may uncover hardware or configuration defects at boot-time rather than when users enable ASPM via sysfs later. Booting with "pcie_aspm=off" prevents this enabling (Manivannan Sadhasivam) - Remove the qcom code that enabled ASPM (Manivannan Sadhasivam) Power management: - If a device has already been disconnected, e.g., by a hotplug removal, don't bother trying to resume it to D0 when detaching the driver. This avoids annoying "Unable to change power state from D3cold to D0" messages (Mario Limonciello) - Ensure devices are powered up before config reads for 'max_link_width', 'current_link_speed', 'current_link_width', 'secondary_bus_number', and 'subordinate_bus_number' sysfs files. This prevents using invalid data (~0) in drivers or lspci and, depending on how the PCIe controller reports errors, may avoid error interrupts or crashes (Brian Norris) Virtualization: - Add rescan/remove locking when enabling/disabling SR-IOV, which avoids list corruption on s390, where disabling SR-IOV also generates hotplug events (Niklas Schnelle) Peer-to-peer DMA: - Free struct p2p_pgmap, not a member within it, in the pci_p2pdma_add_resource() error path (Sungho Kim) Endpoint framework: - Document sysfs interface for BAR assignment of vNTB endpoint functions (Jerome Brunet) - Fix array underflow in endpoint BAR test case (Dan Carpenter) - Skip endpoint IRQ test if the IRQ is out of range to avoid false errors (Christian Bruel) - Fix endpoint test case for controllers with fixed-size BARs smaller than requested by the test (Marek Vasut) - Restore inbound translation when disabling doorbell so the endpoint doorbell test case can be run more than once (Niklas Cassel) - Avoid a NULL pointer dereference when releasing DMA channels in endpoint DMA test case (Shin'ichiro Kawasaki) - Convert tegra194 interrupt number to MSI vector to fix endpoint Kselftest MSI_TEST test case (Niklas Cassel) - Reset tegra194 BARs when running in endpoint mode so the BAR tests don't overwrite the ATU settings in BAR4 (Niklas Cassel) - Handle errors in tegra194 BPMP transactions so we don't mistakenly skip future PERST# assertion (Vidya Sagar) AMD MDB PCIe controller driver: - Update DT binding example to separate PERST# to a Root Port stanza to make multiple Root Ports possible in the future (Sai Krishna Musham) - Add driver support for PERST# being described in a Root Port stanza, falling back to the host bridge if not found there (Sai Krishna Musham) Freescale i.MX6 PCIe controller driver: - Enable the 3.3V Vaux supply if available so devices can request wakeup with either Beacon or WAKE# (Richard Zhu) MediaTek PCIe Gen3 controller driver: - Add optional sys clock ready time setting to avoid sys_clk_rdy signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno) - Add DT binding and driver support for MT6991 and MT8196 (AngeloGioacchino Del Regno) NVIDIA Tegra PCIe controller driver: - When asserting PERST#, disable the controller instead of mistakenly disabling the PLL twice (Nagarjuna Kristam) - Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock nesting error (Marek Vasut) Qualcomm PCIe controller driver: - Select PCI Power Control Slot driver so slot voltage rails can be turned on/off if described in Root Port devicetree node (Qiang Yu) - Parse only PCI bridge child nodes in devicetree, skipping unrelated nodes such as OPP (Operating Performance Points), which caused probe failures (Krishna Chaitanya Chundru) - Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang) - Consolidate Root Port 'phy' and 'reset' properties in struct qcom_pcie_port, regardless of whether we got them from the Root Port node or the host bridge node (Manivannan Sadhasivam) - Fetch and map the ELBI register space in the DWC core rather than in each driver individually (Krishna Chaitanya Chundru) - Enable ECAM mechanism in DWC core by setting up iATU with 'CFG Shift Feature' and use this in the qcom driver (Krishna Chaitanya Chundru) - Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya Chundru) - Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm Glymur, which is compatible with X1E80100 but doesn't have the cnoc_sf_axi clock (Qiang Yu) Renesas R-Car PCIe controller driver: - Fix a typo that prevented correct PHY initialization (Marek Vasut) - Add a missing 1ms delay after PWR reset assertion as required by the V4H manual (Marek Vasut) - Assure reset has completed before DBI access to avoid SError (Marek Vasut) - Fix inverted PHY initialization check, which sometimes led to timeouts and failure to start the controller (Marek Vasut) - Pass the correct IRQ domain to generic_handle_domain_irq() to fix a regression when converting to msi_create_parent_irq_domain() (Claudiu Beznea) - Drop the spinlock protecting the PMSR register - it's no longer required since pci_lock already serializes accesses (Marek Vasut) - Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock nesting error (Marek Vasut) SOPHGO PCIe controller driver: -

Pull networking updates from Paolo Abeni: "Core & protocols: - Improve drop account scalability on NUMA hosts for RAW and UDP sockets and the backlog, almost doubling the Pps capacity under DoS - Optimize the UDP RX performance under stress, reducing contention, revisiting the binary layout of the involved data structs and implementing NUMA-aware locking. This improves UDP RX performance by an additional 50%, even more under extreme conditions - Add support for PSP encryption of TCP connections; this mechanism has some similarities with IPsec and TLS, but offers superior HW offloads capabilities - Ongoing work to support Accurate ECN for TCP. AccECN allows more than one congestion notification signal per RTT and is a building block for Low Latency, Low Loss, and Scalable Throughput (L4S) - Reorganize the TCP socket binary layout for data locality, reducing the number of touched cachelines in the fastpath - Refactor skb deferral free to better scale on large multi-NUMA hosts, this improves TCP and UDP RX performances significantly on such HW - Increase the default socket memory buffer limits from 256K to 4M to better fit modern link speeds - Improve handling of setups with a large number of nexthop, making dump operating scaling linearly and avoiding unneeded synchronize_rcu() on delete - Improve bridge handling of VLAN FDB, storing a single entry per bridge instead of one entry per port; this makes the dump order of magnitude faster on large switches - Restore IP ID correctly for encapsulated packets at GSO segmentation time, allowing GRO to merge packets in more scenarios - Improve netfilter matching performance on large sets - Improve MPTCP receive path performance by leveraging recently introduced core infrastructure (skb deferral free) and adopting recent TCP autotuning changes - Allow bridges to redirect to a backup port when the bridge port is administratively down - Introduce MPTCP 'laminar' endpoint that con be used only once per connection and simplify common MPTCP setups - Add RCU safety to dst->dev, closing a lot of possible races - A significant crypto library API for SCTP, MPTCP and IPv6 SR, reducing code duplication - Supports pulling data from an skb frag into the linear area of an XDP buffer Things we sprinkled into general kernel code: - Generate netlink documentation from YAML using an integrated YAML parser Driver API: - Support using IPv6 Flow Label in Rx hash computation and RSS queue selection - Introduce API for fetching the DMA device for a given queue, allowing TCP zerocopy RX on more H/W setups - Make XDP helpers compatible with unreadable memory, allowing more easily building DevMem-enabled drivers with a unified XDP/skbs datapath - Add a new dedicated ethtool callback enabling drivers to provide the number of RX rings directly, improving efficiency and clarity in RX ring queries and RSS configuration - Introduce a burst period for the health reporter, allowing better handling of multiple errors due to the same root cause - Support for DPLL phase offset exponential moving average, controlling the average smoothing factor Device drivers: - Add a new Huawei driver for 3rd gen NIC (hinic3) - Add a new SpacemiT driver for K1 ethernet MAC - Add a generic abstraction for shared memory communication devices (dibps) - Ethernet high-speed NICs: -

Pull block updates from Jens Axboe: - NVMe pull request via Keith: - FC target fixes (Daniel) - Authentication fixes and updates (Martin, Chris) - Admin controller handling (Kamaljit) - Target lockdep assertions (Max) - Keep-alive updates for discovery (Alastair) - Suspend quirk (Georg) - MD pull request via Yu: - Add support for a lockless bitmap. A key feature for the new bitmap are that the IO fastpath is lockless. If a user issues lots of write IO to the same bitmap bit in a short time, only the first write has additional overhead to update bitmap bit, no additional overhead for the following writes. By supporting only resync or recover written data, means in the case creating new array or replacing with a new disk, there is no need to do a full disk resync/recovery. - Switch ->getgeo() and ->bios_param() to using struct gendisk rather than struct block_device. - Rust block changes via Andreas. This series adds configuration via configfs and remote completion to the rnull driver. The series also includes a set of changes to the rust block device driver API: a few cleanup patches, and a few features supporting the rnull changes. The series removes the raw buffer formatting logic from `kernel::block` and improves the logic available in `kernel::string` to support the same use as the removed logic. - floppy arch cleanups - Reduce the number of dereferencing needed for ublk commands - Restrict supported sockets for nbd. Mostly done to eliminate a class of issues perpetually reported by syzbot, by using nonsensical socket setups. - A few s390 dasd block fixes - Fix a few issues around atomic writes - Improve DMA interation for integrity requests - Improve how iovecs are treated with regards to O_DIRECT aligment constraints. We used to require each segment to adhere to the constraints, now only the request as a whole needs to. - Clean up and improve p2p support, enabling use of p2p for metadata payloads - Improve locking of request lookup, using SRCU where appropriate - Use page references properly for brd, avoiding very long RCU sections - Fix ordering of recursively submitted IOs - Clean up and improve updating nr_requests for a live device - Various fixes and cleanups * tag 'for-6.18/block-20250929' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (164 commits) s390/dasd: enforce dma_alignment to ensure proper buffer validation s390/dasd: Return BLK_STS_INVAL for EINVAL from do_dasd_request ublk: remove redundant zone op check in ublk_setup_iod() nvme: Use non zero KATO for persistent discovery connections nvmet: add safety check for subsys lock nvme-core: use nvme_is_io_ctrl() for I/O controller check nvme-core: do ioccsz/iorcsz validation only for I/O controllers nvme-core: add method to check for an I/O controller blk-cgroup: fix possible deadlock while configuring policy blk-mq: fix null-ptr-deref in blk_mq_free_tags() from error path blk-mq: Fix more tag iteration function documentation selftests: ublk: fix behavior when fio is not installed ublk: don't access ublk_queue in ublk_unmap_io() ublk: pass ublk_io to __ublk_complete_rq() ublk: don't access ublk_queue in ublk_need_complete_req() ublk: don't access ublk_queue in ublk_check_commit_and_fetch() ublk: don't pass ublk_queue to ublk_fetch() ublk: don't access ublk_queue in ublk_config_io_buf() ublk: don't access ublk_queue in ublk_check_fetch_buf() ublk: pass q_id and tag to __ublk_check_and_get_req() ...
