Title
ata: libata-scsi: fix DSM TRIM for sector sizes larger than 2048 bytes
Summary
In the Linux kernel, the following vulnerability has been resolved: ata: libata-scsi: fix DSM TRIM for sector sizes larger than 2048 bytes ata_scsi_write_same_xlat() translates a SCSI WRITE SAME command with the UNMAP bit set into an ATA DATA SET MANAGEMENT TRIM command. The TRIM descriptor is built by ata_format_dsm_trim_descr() into the 2048-byte ata_scsi_rbuf staging buffer, and the number of bytes copied is compared against the logical sector size by the caller: size = ata_format_dsm_trim_descr(scmd, trmax, block, n_block); if (size != len) /* len == sdp->sector_size */ goto invalid_param_len; ata_format_dsm_trim_descr() clamps the copy length to ATA_SCSI_RBUF_SIZE (2048). On a device whose logical sector size exceeds that (e.g. a 4Kn device, where sector_size == 4096) the function can never return more than 2048, while the caller expects it to return sector_size. The comparison therefore always fails, so every TRIM is rejected with "Parameter list length error" and WARN_ON() splats on each attempt. TRIM / discard is thus completely broken on such devices. The descriptor was incorrectly sized from the logical sector size. A DSM TRIM payload is a list of 512-byte pages, each holding up to ATA_MAX_TRIM_RNUM (64) LBA Range Entries, and is independent of the logical sector size. The Block Limits VPD page already advertises a single such page as the maximum WRITE SAME length (65535 * ATA_MAX_TRIM_RNUM logical blocks), so the block layer never sends a request that needs more than one page. Emit exactly one 512-byte page, independent of the logical sector size, and transfer only that page (COUNT == 1). For a 512-byte-sector device this is unchanged; devices with larger logical sectors now work instead of failing every TRIM.

Passthrough WRITE SAME is rejected, so there is no write or code-execution primitive.\nA:H - WARN_ON() taints the kernel and panics when panic_on_warn is set or warn_limit is exceeded. Because it is not WARN_ON_ONCE, a remote initiator can repeat UNMAP to flood logs and force a host panic, and TRIM/discard is completely broken on 4Kn ATA volumes."

The TRIM\\ndescriptor is built by ata_format_dsm_trim_descr() into the 2048-byte\\nata_scsi_rbuf staging buffer, and the number of bytes copied is compared\\nagainst the logical sector size by the caller:\\n\\n\\tsize = ata_format_dsm_trim_descr(scmd, trmax, block, n_block);\\n\\tif (size != len)\\t\\t/* len == sdp-\u003esector_size */\\n\\t\\tgoto invalid_param_len;\\n\\nata_format_dsm_trim_descr() clamps the copy length to ATA_SCSI_RBUF_SIZE\\n(2048).  On a device whose logical sector size exceeds that (e.g. a 4Kn\\ndevice, where sector_size == 4096) the function can never return more than\\n2048, while the caller expects it to return sector_size.  The comparison\\ntherefore always fails, so every TRIM is rejected with \\\"Parameter list\\nlength error\\\" and WARN_ON() splats on each attempt.  TRIM / discard is\\nthus completely broken on such devices.\\n\\nThe descriptor was incorrectly sized from the logical sector size.  A DSM\\nTRIM payload is a list of 512-byte pages, each holding up to\\nATA_MAX_TRIM_RNUM (64) LBA Range Entries, and is independent of the logical\\nsector size.  The Block Limits VPD page already advertises a single such\\npage as the maximum WRITE SAME length (65535 * ATA_MAX_TRIM_RNUM logical\\nblocks), so the block layer never sends a request that needs more than one\\npage.\\n\\nEmit exactly one 512-byte page, independent of the logical sector size,\\nand transfer only that page (COUNT == 1).  For a 512-byte-sector device\\nthis is unchanged; devices with larger logical sectors now work instead of\\nfailing every TRIM.\"}],\"affected\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"affectedData\":[{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"drivers/ata/libata-scsi.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"ef2d7392c4ece5c3cd12a6c7ca9366cd8f189aff\",\"lessThan\":\"07975b8daa3b0ab3cbc02cc48ea7bc48fadcec53\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"ef2d7392c4ece5c3cd12a6c7ca9366cd8f189aff\",\"lessThan\":\"b7b5ab2df325ffbbad7ca2debaa071e024d68cb5\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"ef2d7392c4ece5c3cd12a6c7ca9366cd8f189aff\",\"lessThan\":\"07baa310ea3224a7044b1ca84796bb37a235af1f\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"ef2d7392c4ece5c3cd12a6c7ca9366cd8f189aff\",\"lessThan\":\"977554ed91b54075fbc0bac536316b4841ef6258\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"ef2d7392c4ece5c3cd12a6c7ca9366cd8f189aff\",\"lessThan\":\"04e2befe25792f2e90097f284d7e86fc6bcfe928\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"ef2d7392c4ece5c3cd12a6c7ca9366cd8f189aff\",\"lessThan\":\"c2e3dccd6870659851eaa4c12ab16418b8e3040a\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"ef2d7392c4ece5c3cd12a6c7ca9366cd8f189aff\",\"lessThan\":\"4a4268a0b0a595bd9534cf9c7fda93775a7d8a0d\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"ef2d7392c4ece5c3cd12a6c7ca9366cd8f189aff\",\"lessThan\":\"79cce911e623c0baa0fde307ce3a434e084b881a\",\"versionType\":\"git\",\"status\":\"affected\"}]},{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"affected\",\"programFiles\":[\"drivers/ata/libata-scsi.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"4.9\",\"status\":\"affected\"},{\"version\":\"0\",\"lessThan\":\"4.9\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.10.270\",\"lessThanOrEqual\":\"5.10.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.15.221\",\"lessThanOrEqual\":\"5.15.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.1.188\",\"lessThanOrEqual\":\"6.1.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.6.157\",\"lessThanOrEqual\":\"6.6.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.12.109\",\"lessThanOrEqual\":\"6.12.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.18.50\",\"lessThanOrEqual\":\"6.18.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"7.2.4\",\"lessThanOrEqual\":\"7.2.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"7.3-rc1\",\"lessThanOrEqual\":\"*\",\"versionType\":\"original_commit_for_fix\",\"status\":\"unaffected\"}]}]}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H\",\"baseScore\":8.2,\"baseSeverity\":\"HIGH\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"LOW\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"HIGH\"},\"exploitabilityScore\":3.9,\"impactScore\":4.2}]},\"references\":[{\"url\":\"https://git.kernel.org/stable/c/04e2befe25792f2e90097f284d7e86fc6bcfe928\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/07975b8daa3b0ab3cbc02cc48ea7bc48fadcec53\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/07baa310ea3224a7044b1ca84796bb37a235af1f\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/4a4268a0b0a595bd9534cf9c7fda93775a7d8a0d\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/79cce911e623c0baa0fde307ce3a434e084b881a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/977554ed91b54075fbc0bac536316b4841ef6258\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/b7b5ab2df325ffbbad7ca2debaa071e024d68cb5\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/c2e3dccd6870659851eaa4c12ab16418b8e3040a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"}]}}",
