[ Upstream commit fa2408a24f8f0db14d9cfc613ef162dc267d7ad4 ]

The logic at ghes_new() prevents allocating too large records, by
checking if they're bigger than GHES_ESTATUS_MAX_SIZE (currently, 64KB).
Yet, the allocation is done with the actual number of pages from the
CPER bios table location, which can be smaller.

Yet, a bad firmware could send data with a different size, which might
be bigger than the allocated memory, causing an OOPS:

[ Upstream commit 42b12cb5fd4554679bac06bbdd05dc8b643bcc42 ]

syzbot correctly reports this as a KCSAN race, as ctx->cached_cq_tail
should be read under ->uring_lock. This isn't immediately feasible in
io_flush_timeouts(), but as long as we read a stable value, that should
be good enough. If two io-wq threads compete on this value, then they
will both end up calling io_flush_timeouts() and at least one of them
will see the correct value.

[ Upstream commit eae21beecb95a3b69ee5c38a659f774e171d730e ]

There's a logic inside GHES/CPER to detect if the section_length
is too small, but it doesn't detect if it is too big.

Currently, if the firmware receives an ARM processor CPER record
stating that a section length is big, kernel will blindly trust
section_length, producing a very long dump. For instance, a 67
bytes record with ERR_INFO_NUM set 46198 and section length
set to 854918320 would dump a lot of data going a way past the
firmware memory-mapped area.

Fix it by adding a logic to prevent it to go past the buffer
if ERR_INFO_NUM is too big, making it report instead:

	[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 1
	[Hardware Error]: event severity: recoverable
	[Hardware Error]:  Error 0, type: recoverable
	[Hardware Error]:   section_type: ARM processor error
	[Hardware Error]:   MIDR: 0xff304b2f8476870a
	[Hardware Error]:   section length: 854918320, CPER size: 67
	[Hardware Error]:   section length is too big
	[Hardware Error]:   firmware-generated error record is incorrect
	[Hardware Error]:   ERR_INFO_NUM is 46198

[ Upstream commit cefcb9297fbdb6d94b61787b4f8d84f55b741470 ]

When using device-mapper's dm-raid target, stopping a RAID array can cause
the system to hang under specific conditions.

This occurs when:

- A dm-raid managed device tree is suspended from top to bottom
   (the top-level RAID device is suspended first, followed by its
    underlying metadata and data devices)

- The top-level RAID device is then removed

Removing the top-level device triggers a hang in the following sequence:
the dm-raid destructor calls md_stop(), which tries to flush the
write-intent bitmap by writing to the metadata sub-devices. However, these
devices are already suspended, making them unable to complete the write-intent
operations and causing an indefinite block.

Fix:

- Prevent bitmap flushing when md_stop() is called from dm-raid
destructor context
  and avoid a quiescing/unquescing cycle which could also cause I/O

- Still allow write-intent bitmap flushing when called from dm-raid
suspend context

This ensures that RAID array teardown can complete successfully even when the
underlying devices are in a suspended state.

This second patch uses md_is_rdwr() to distinguish between suspend and
destructor paths as elaborated on above.

[ Upstream commit 6028f59620927aee2e15a424004012ae05c50684 ]

xe_vma_userptr_pin_pages can return -EBUSY but -EBUSY has special
meaning in VM bind IOCTLs that user fence is pending that is attached to
the VMA. Convert -EBUSY to -ENOMEM in this case as -EBUSY in practice
means we are low or out of memory.

Build the image locally: `podman build -f build/dockerfiles/assembly.Dockerfile -t neoche:local .`\n2. Run standalone: `podman run --rm -p 7681:7681 neoche:local` and open http://localhost:7681\n3. Verify Neovim starts and ttyd renders correctly in the browser\n4. Test distribution bootstrapping: `podman run --rm -p 7681:7681 -e NVIM_DISTRO=lazyvim neoche:local`\n5. Push to registry: `podman push neoche:local quay.io/neoche/neovim:insiders`\n6. Deploy ConfigMap to OCP: `oc apply -f registration/configmap.yaml -n <che-namespace>`\n7. Launch workspace: navigate to Dev Spaces dashboard with `?che-editor=neoche/neovim/insiders`\n8. Verify init container runs, neovim-runtime launches, and ttyd is accessible at the workspace endpoint\n\n## Build Order\n\nSteps 1-4 can be built and tested incrementally:\n1.

Build the image locally: `podman build -f build/dockerfiles/assembly.Dockerfile -t neoche:local .`\n2. Run standalone: `podman run --rm -p 7681:7681 neoche:local` and open http://localhost:7681\n3. Verify Neovim starts and ttyd renders correctly in the browser\n4. Test distribution bootstrapping: `podman run --rm -p 7681:7681 -e NVIM_DISTRO=lazyvim neoche:local`\n5. Push to registry: `podman push neoche:local quay.io/neoche/neovim:insiders`\n6. Deploy ConfigMap to OCP: `oc apply -f registration/configmap.yaml -n <che-namespace>`\n7. Launch workspace: navigate to Dev Spaces dashboard with `?che-editor=neoche/neovim/insiders`\n8. Verify init container runs, neovim-runtime launches, and ttyd is accessible at the workspace endpoint\n\n## Build Order\n\nSteps 1-4 can be built and tested incrementally:\n1. Step 1 (init) + Step 2 (scripts) + Step 3 (Dockerfile) -> local standalone test\n2. Step 4 (editor definition) + Step 5 (ConfigMap) -> OCP integration test\n3. Step 6 (Makefile) -> automation\n","structuredPatch":[],"originalFile":null},"sourceToolAssistantUUID":"cb4d4cbc-c1c8-4cd5-a25f-468aada2a99f"}

This project builds `neoche`, a first-class Neovim editor plugin following the exact patterns established by `che-incubator/che-code`, using ttyd as the web terminal frontend. It targets both Josie's OCP cluster (via oc builds) and general-purpose open source use.\n\n## Reference Material\n\n- `che-incubator/che-code` (cloned at `/tmp/che-code`): canonical editor implementation\n  - `/tmp/che-code/build/dockerfiles/assembly.Dockerfile` -- multi-stage assembly pattern\n  - `/tmp/che-code/build/scripts/entrypoint-init-container.sh` -- binary injection\n  - `/tmp/che-code/build/scripts/entrypoint-volume.sh` -- runtime platform detection + launch\n  - `/tmp/che-code/build/scripts/entrypoint.sh` -- standalone direct-run mode\n- `/tmp/che-plugin-registry/che-editors.yaml` -- editor definition format (Devfile v2.2.2)\n  - Lines 1-93: che-code insiders definition (primary reference)\n  - Lines 181-288: che-idea definition (alternative reference)\n\n## Project Structure\n\n```\nneoche/\n├── build/\n│   ├── dockerfiles/\n│   │   └── assembly.Dockerfile\n│   └── scripts/\n│       ├── entrypoint.sh\n│       ├── entrypoint-init-container.sh\n│       ├── entrypoint-volume.sh\n│       └── bootstrap-distro.sh\n├── editor-definition.yaml\n├── registration/\n│   └── configmap.yaml\n├── Makefile\n└── LICENSE\n```\n\n## Implementation Steps\n\n### Step 1: Initialize the project\n\n- `git init` in `/home/josie/development/personal/neoche`\n- Create the directory structure: `build/dockerfiles/`, `build/scripts/`, `registration/`\n- Add EPL-2.0 LICENSE file\n- Initial commit\n\n### Step 2: Write the entrypoint scripts\n\nAll scripts go in `build/scripts/`. These are the runtime glue.\n\n**`entrypoint-init-container.sh`** (reference: `/tmp/che-code/build/scripts/entrypoint-init-container.sh`)\n- Copy `/neovim-linux-*` directories to `/neovim/` shared volume\n- Copy ttyd binaries to `/neovim/bin/`\n- Copy machine-exec to `/neovim/bin/`\n- Copy `entrypoint-volume.sh` and `bootstrap-distro.sh` to `/neovim/`\n\n**`entrypoint-volume.sh`** (reference: `/tmp/che-code/build/scripts/entrypoint-volume.sh`)\n- Non-root user handling: if `whoami` fails and `/etc/passwd` is writable, append user entry (same pattern as che-code lines 62-67)\n- Start machine-exec in background on port 3333: `nohup /neovim/bin/machine-exec --url \"127.0.0.1:3333\" &`\n- Platform detection via `ldd /bin/ls`:\n  - If musl detected: `NVIM_DIR=/neovim/neovim-linux-musl`, `TTYD_BIN=/neovim/bin/ttyd-musl`\n  - Else (glibc): `NVIM_DIR=/neovim/neovim-linux-libc`, `TTYD_BIN=/neovim/bin/ttyd`\n- Set `PATH=$NVIM_DIR/bin:$PATH`, `TERM=xterm-256color`\n- Run `bootstrap-distro.sh` if `NVIM_DISTRO` is set\n- `cd ${PROJECT_SOURCE:-/projects}`\n- `exec $TTYD_BIN -W -p 7681 --writable -t fontSize=14 -t fontFamily=\"monospace\" nvim .`\n\n**`entrypoint.sh`** (standalone/direct-run mode)\n- Simplified version without volume paths -- launches ttyd+nvim directly from image paths\n- Used when running the image standalone (outside Che), useful for testing\n\n**`bootstrap-distro.sh`**\n- If `$HOME/.config/nvim` exists, exit early (respect user config)\n- Switch on `$NVIM_DISTRO`:\n  - `lazyvim`: clone `https://github.com/LazyVim/starter`\n  - `astrovim`: clone `https://github.com/AstroNvim/template`\n  - `nvchad`: clone `https://github.com/NvChad/starter`\n  - `kickstart`: clone `https://github.com/nvim-lua/kickstart.nvim`\n- Remove `.git` directory from cloned config\n- Log which distribution was bootstrapped\n\n### Step 3: Write the assembly Dockerfile\n\nFile: `build/dockerfiles/assembly.Dockerfile`\n\nReference: `/tmp/che-code/build/dockerfiles/assembly.Dockerfile`\n\n```\n# Stage 1: Download Neovim glibc portable build\nFROM registry.access.redhat.com/ubi9/ubi-minimal:latest AS nvim-libc-downloader\nRUN microdnf install -y tar gzip && microdnf clean all\nARG NVIM_VERSION=v0.10.4\nRUN curl -fsSL https://github.com/neovim/neovim/releases/download/${NVIM_VERSION}/nvim-linux-x86_64.tar.gz \\\n    | tar xz -C /opt && mv /opt/nvim-linux-x86_64 /neovim-linux-libc\n\n# Stage 2: Download Neovim AppImage and extract for musl\nFROM alpine:3.21 AS nvim-musl-downloader\nRUN apk add --no-cache curl fuse\nARG NVIM_VERSION=v0.10.4\nRUN curl -fsSL -o /tmp/nvim.appimage \\\n    https://github.com/neovim/neovim/releases/download/${NVIM_VERSION}/nvim-linux-x86_64.appimage \\\n    && chmod +x /tmp/nvim.appimage \\\n    && /tmp/nvim.appimage --appimage-extract \\\n    && mv /squashfs-root /neovim-linux-musl\n\n# Stage 3: Download ttyd binaries (both glibc and static musl)\nFROM registry.access.redhat.com/ubi9/ubi-minimal:latest AS ttyd-downloader\nRUN microdnf install -y curl && microdnf clean all\nARG TTYD_VERSION=1.7.7\nRUN mkdir -p /ttyd-bin \\\n    && curl -fsSL -o /ttyd-bin/ttyd \\\n       https://github.com/tsl0922/ttyd/releases/download/${TTYD_VERSION}/ttyd.x86_64 \\\n    && curl -fsSL -o /ttyd-bin/ttyd-musl \\\n       https://github.com/tsl0922/ttyd/releases/download/${TTYD_VERSION}/ttyd.x86_64-musl \\\n    && chmod +x /ttyd-bin/*\n\n# Stage 4: machine-exec\nFROM quay.io/eclipse/che-machine-exec:7.56.0 AS machine-exec\n\n# Stage 5: Build the rootfs\nFROM registry.access.redhat.com/ubi9/ubi-minimal:latest AS rootfs-builder\nRUN mkdir -p /mnt/rootfs\nRUN microdnf --installroot /mnt/rootfs install -y \\\n    ncurses-libs coreutils glibc-minimal-langpack bash \\\n    && microdnf --installroot /mnt/rootfs clean all\nRUN rm -rf /mnt/rootfs/var/cache/* /mnt/rootfs/var/log/dnf* /mnt/rootfs/var/log/yum.*\n\nWORKDIR /mnt/rootfs\n\nCOPY --from=nvim-libc-downloader --chown=0:0 /neovim-linux-libc /mnt/rootfs/neovim-linux-libc\nCOPY --from=nvim-musl-downloader --chown=0:0 /neovim-linux-musl /mnt/rootfs/neovim-linux-musl\nCOPY --from=ttyd-downloader --chown=0:0 /ttyd-bin /mnt/rootfs/neovim-bin\nCOPY --from=machine-exec --chown=0:0 /go/bin/che-machine-exec /mnt/rootfs/neovim-bin/machine-exec\n\nRUN mkdir -p /mnt/rootfs/projects /mnt/rootfs/home/che /mnt/rootfs/bin\nRUN cat /mnt/rootfs/etc/passwd | sed 's#root:x.*#root:x:${USER_ID}:${GROUP_ID}::${HOME}:/bin/bash#g' \\\n    > /mnt/rootfs/home/che/.passwd.template \\\n    && cat /mnt/rootfs/etc/group | sed 's#root:x:0:#root:x:0:0,${USER_ID}:#g' \\\n    > /mnt/rootfs/home/che/.group.template\nRUN for f in \"/mnt/rootfs/neovim-bin/\" \"/mnt/rootfs/home/che\" \"/mnt/rootfs/etc/group\" \"/mnt/rootfs/projects\";

If not, build Neovim from source in an Alpine stage instead.\n\n### Step 4: Write the editor definition\n\nFile: `editor-definition.yaml`\n\nReference: `/tmp/che-plugin-registry/che-editors.yaml` lines 1-93\n\n```yaml\nschemaVersion: 2.2.2\nmetadata:\n  name: neoche/neovim/insiders\n  displayName: Neovim\n  description: Neovim terminal editor for Eclipse Che via ttyd\n  icon: /images/neovim.svg\n  tags:\n    - Tech-Preview\n  attributes:\n    publisher: neoche\n    version: insiders\n    title: Neovim terminal editor for Eclipse Che\n    repository: https://github.com/josie/neoche\n    firstPublicationDate: '2026-03-03'\ncommands:\n  - id: init-container-command\n    apply:\n      component: neovim-injector\n  - id: init-neovim-command\n    exec:\n      component: neovim-runtime\n      commandLine: >-\n        nohup /neovim/entrypoint-volume.sh > /neovim/entrypoint-logs.txt 2>&1 &\nevents:\n  preStart:\n    - init-container-command\n  postStart:\n    - init-neovim-command\ncomponents:\n  - name: neovim-injector\n    container:\n      image: 'quay.io/neoche/neovim:insiders'\n      command:\n        - /entrypoint-init-container.sh\n      volumeMounts:\n        - name: neovim\n          path: /neovim\n      memoryLimit: 256Mi\n      memoryRequest: 32Mi\n      cpuLimit: 500m\n      cpuRequest: 30m\n  - name: neovim-runtime\n    container:\n      image: 'quay.io/devfile/universal-developer-image:latest'\n      memoryLimit: 512Mi\n      memoryRequest: 128Mi\n      cpuLimit: 500m\n      cpuRequest: 30m\n      env:\n        - name: NVIM_DISTRO\n          value: ''\n      volumeMounts:\n        - name: neovim\n          path: /neovim\n      endpoints:\n        - name: neovim\n          attributes:\n            type: main\n            cookiesAuthEnabled: true\n            discoverable: false\n            urlRewriteSupported: true\n          targetPort: 7681\n          exposure: public\n          secure: true\n          protocol: https\n    attributes:\n      app.kubernetes.io/component: neovim-runtime\n      app.kubernetes.io/part-of: neoche.eclipse.org\n      controller.devfile.io/container-contribution: true\n  - name: neovim\n    volume: {}\n```\n\n### Step 5: Write the OCP registration ConfigMap\n\nFile: `registration/configmap.yaml`\n\n```yaml\napiVersion: v1\nkind: ConfigMap\nmetadata:\n  name: neovim-editor-definition\n  labels:\n    app.kubernetes.io/component: editor-definition\n    app.kubernetes.io/part-of: che.eclipse.org\n  annotations:\n    che.eclipse.org/editor-id: neoche/neovim/insiders\ndata:\n  editor-definition.yaml: |\n    <contents of editor-definition.yaml inlined here>\n```\n\n### Step 6: Write the Makefile\n\nTargets:\n- `build`: Build the assembly image via `podman build` (or `oc start-build` for OCP)\n- `push`: Push to quay.io/neoche/neovim\n- `deploy-configmap`: `oc apply -f registration/configmap.yaml`\n- `test-standalone`: Run the image locally with `podman run -p 7681:7681`\n- `test-che`: Print the URL to launch a workspace with this editor\n- `clean`: Remove built images\n\n### Step 7: Initial testing\n\n1. **Local standalone test**: `make test-standalone` -> open http://localhost:7681 -> verify Neovim loads in browser\n2. **Distribution test**: Run with `-e NVIM_DISTRO=lazyvim` -> verify LazyVim bootstraps on first launch\n3. **OCP deploy test**: Push image, apply ConfigMap, launch a workspace with `?che-editor=neoche/neovim/insiders`\n4. **Platform test**: Verify entrypoint-volume.sh correctly detects glibc in UDI and selects the right binary\n\n## Verification\n\n1. Build the image locally: `podman build -f build/dockerfiles/assembly.Dockerfile -t neoche:local .`\n2. Run standalone: `podman run --rm -p 7681:7681 neoche:local` and open http://localhost:7681\n3. Verify Neovim starts and ttyd renders correctly in the browser\n4. Test distribution bootstrapping: `podman run --rm -p 7681:7681 -e NVIM_DISTRO=lazyvim neoche:local`\n5. Push to registry: `podman push neoche:local quay.io/neoche/neovim:insiders`\n6. Deploy ConfigMap to OCP: `oc apply -f registration/configmap.yaml -n <che-namespace>`\n7. Launch workspace: navigate to Dev Spaces dashboard with `?che-editor=neoche/neovim/insiders`\n8. Verify init container runs, neovim-runtime launches, and ttyd is accessible at the workspace endpoint\n\n## Build Order\n\nSteps 1-4 can be built and tested incrementally:\n1. Step 1 (init) + Step 2 (scripts) + Step 3 (Dockerfile) -> local standalone test\n2. Step 4 (editor definition) + Step 5 (ConfigMap) -> OCP integration test\n3. Step 6 (Makefile) -> automation\n"},"caller":{"type":"direct"}}],"stop_reason":"tool_use","stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":88,"cache_read_input_tokens":68468,"output_tokens":353,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":88,"ephemeral_5m_input_tokens":0},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CYgVC6jpvx7WxyhDubLwa","type":"assistant","uuid":"e3725c5a-081b-4c7e-812d-e73fd9419807","timestamp":"2026-03-03T16:47:12.725Z"}
