Esta serie corrige errores de desreferencia de puntero nulo que ocurren al usar nilfs2 y dos puntos de seguimiento relacionados con bloques. Este parche (de 2): Se ha informado que al usar el punto de seguimiento \\\"block:block_touch_buffer\\\", touch_buffer() llamado desde __nilfs_get_folio_block() causa una desreferencia de puntero NULL o un error de protecci\u00f3n general cuando KASAN est\u00e1 habilitado. Esto sucede porque, dado que el punto de seguimiento se agreg\u00f3 en touch_buffer(), hace referencia al miembro dev_t bh-\u0026gt;b_bdev-\u0026gt;bd_dev independientemente de si el cabezal del b\u00fafer tiene un puntero a una estructura block_device. En la implementaci\u00f3n actual, la estructura block_device se establece despu\u00e9s de que la funci\u00f3n regresa al llamador. Aqu\u00ed, touch_buffer() se utiliza para marcar el folio/p\u00e1gina que posee el encabezado del b\u00fafer como accedido, pero el asistente de b\u00fasqueda com\u00fan para folio/p\u00e1gina utilizado por la funci\u00f3n de llamada se optimiz\u00f3 para marcar el folio/p\u00e1gina como accedido cuando se reimplement\u00f3 hace mucho tiempo, eliminando la necesidad de llamar a touch_buffer() aqu\u00ed en primer lugar. Por lo tanto, esto resuelve el problema al eliminar la llamada a touch_buffer() en s\u00ed.\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H\",\"baseScore\":5.5,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"NONE\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":3.6}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-476\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"3.9\",\"versionEndExcluding\":\"6.1.119\",\"matchCriteriaId\":\"B9F07E74-2989-4705-AED1-FEACA2FEF716\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.6.0\",\"versionEndExcluding\":\"6.6.63\",\"matchCriteriaId\":\"DC8AE946-6593-4D8D-863A-0BC137CF667F\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.11.0\",\"versionEndExcluding\":\"6.11.10\",\"matchCriteriaId\":\"5D7D3F96-FD78-48BB-9935-3CD41775FEAA\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/085556bf8c70e2629e02e79268dac3016a08b8bf\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/3b2a4fd9bbee77afdd3ed5a05a0c02b6cde8d3b9\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/59b49ca67cca7b007a5afd3de0283c8008157665\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/77e47f89d32c2d72eb33d0becbce7abe14d061f4\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/cd45e963e44b0f10d90b9e6c0e8b4f47f3c92471\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]}]}}"
