+Subject: libata: Apply NOLPM quirk to Crucial M500 480 and 960GB SSDs
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+commit 62ac3f7305470e3f52f159de448bc1a771717e88 upstream.
+
+There have been reports of the Crucial M500 480GB model not working
+with LPM set to min_power / med_power_with_dipm level.
+
+It has not been tested with medium_power, but that typically has no
+measurable power-savings.
+
+Note the reporters Crucial_CT480M500SSD3 has a firmware version of MU03
+and there is a MU05 update available, but that update does not mention any
+LPM fixes in its changelog, so the quirk matches all firmware versions.
+
+In my experience the LPM problems with (older) Crucial SSDs seem to be
+limited to higher capacity versions of the SSDs (different firmware?),
+so this commit adds a NOLPM quirk for the 480 and 960GB versions of the
+M500, to avoid LPM causing issues with these SSDs.

+Subject: libata: Apply NOLPM quirk to Crucial MX100 512GB SSDs
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+commit 9c7be59fc519af9081c46c48f06f2b8fadf55ad8 upstream.
+
+Various people have reported the Crucial MX100 512GB model not working
+with LPM set to min_power. I've now received a report that it also does
+not work with the new med_power_with_dipm level.
+
+It does work with medium_power, but that has no measurable power-savings
+and given the amount of people being bitten by the other levels not
+working, this commit just disables LPM altogether.
+
+Note all reporters of this have either the 512GB model (max capacity), or
+are not specifying their SSD's size. So for now this quirk assumes this is
+a problem with the 512GB model only.

+Subject: libata: disable LPM for Crucial BX100 SSD 500GB drive
+
+From: Kai-Heng Feng <kai.heng.feng@canonical.com>
+
+commit b17e5729a630d8326a48ec34ef02e6b4464a6aef upstream.
+
+After Laptop Mode Tools starts to use min_power for LPM, a user found
+out Crucial BX100 SSD can't get mounted.
+
+Crucial BX100 SSD 500GB drive don't work well with min_power. This also
+happens to med_power_with_dipm.
+
+So let's disable LPM for Crucial BX100 SSD 500GB drive.

+Subject: libata: fix length validation of ATAPI-relayed SCSI commands
+
+From: Eric Biggers <ebiggers@google.com>
+
+commit 058f58e235cbe03e923b30ea7c49995a46a8725f upstream.
+
+syzkaller reported a crash in ata_bmdma_fill_sg() when writing to
+/dev/sg1.  The immediate cause was that the ATA command's scatterlist
+was not DMA-mapped, which causes 'pi - 1' to underflow, resulting in a
+write to 'qc->ap->bmdma_prd[0xffffffff]'.
+
+Strangely though, the flag ATA_QCFLAG_DMAMAP was set in qc->flags.  The
+root cause is that when __ata_scsi_queuecmd() is preparing to relay a
+SCSI command to an ATAPI device, it doesn't correctly validate the CDB
+length before copying it into the 16-byte buffer 'cdb' in 'struct
+ata_queued_cmd'.  Namely, it validates the fixed CDB length expected
+based on the SCSI opcode but not the actual CDB length, which can be
+larger due to the use of the SG_NEXT_CMD_LEN ioctl.  Since 'flags' is
+the next member in ata_queued_cmd, a buffer overflow corrupts it.
+
+Fix it by requiring that the actual CDB length be <= 16 (ATAPI_CDB_LEN).
+
+[Really it seems the length should be required to be <= dev->cdb_len,
+but the current behavior seems to have been intentionally introduced by
+commit 607126c2a21c ("libata-scsi: be tolerant of 12-byte ATAPI commands
+in 16-byte CDBs") to work around a userspace bug in mplayer.  Probably
+the workaround is no longer needed (mplayer was fixed in 2007), but
+continuing to allow lengths to up 16 appears harmless for now.]
+
+Here's a reproducer that works in QEMU when /dev/sg1 refers to the
+CD-ROM drive that qemu-system-x86_64 creates by default:
+
+    #include <fcntl.h>
+    #include <sys/ioctl.h>
+    #include <unistd.h>
+
+    #define SG_NEXT_CMD_LEN 0x2283
+
+    int main()
+    {
+           char buf[53] = { [36] = 0x7e, [52] = 0x02 };
+           int fd = open("/dev/sg1", O_RDWR);
+           ioctl(fd, SG_NEXT_CMD_LEN, &(int){ 17 });
+           write(fd, buf, sizeof(buf));
+    }
+
+The crash was:

+Subject: libata: Make Crucial BX100 500GB LPM quirk apply to all firmware versions
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+commit 3bf7b5d6d017c27e0d3b160aafb35a8e7cfeda1f upstream.
+
+Commit b17e5729a630 ("libata: disable LPM for Crucial BX100 SSD 500GB
+drive"), introduced a ATA_HORKAGE_NOLPM quirk for Crucial BX100 500GB SSDs
+but limited this to the MU02 firmware version, according to:
+http://www.crucial.com/usa/en/support-ssd-firmware
+
+MU02 is the last version, so there are no newer possibly fixed versions
+and if the MU02 version has broken LPM then the MU01 almost certainly
+also has broken LPM, so this commit changes the quirk to apply to all
+firmware versions.

+Subject: libata: Modify quirks for MX100 to limit NCQ_TRIM quirk to MU01 version
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+commit d418ff56b8f2d2b296daafa8da151fe27689b757 upstream.
+
+When commit 9c7be59fc519af ("libata: Apply NOLPM quirk to Crucial MX100
+512GB SSDs") was added it inherited the ATA_HORKAGE_NO_NCQ_TRIM quirk
+from the existing "Crucial_CT*MX100*" entry, but that entry sets model_rev
+to "MU01", where as the entry adding the NOLPM quirk sets it to NULL.
+
+This means that after this commit we no apply the NO_NCQ_TRIM quirk to
+all "Crucial_CT512MX100*" SSDs even if they have the fixed "MU02"
+firmware. This commit splits the "Crucial_CT512MX100*" quirk into 2
+quirks, one for the "MU01" firmware and one for all other firmware
+versions, so that we once again only apply the NO_NCQ_TRIM quirk to the
+"MU01" firmware version.

+Subject: libata: remove WARN() for DMA or PIO command without data
+
+From: Eric Biggers <ebiggers@google.com>
+
+commit 9173e5e80729c8434b8d27531527c5245f4a5594 upstream.
+
+syzkaller hit a WARN() in ata_qc_issue() when writing to /dev/sg0.  This
+happened because it issued a READ_6 command with no data buffer.
+
+Just remove the WARN(), as it doesn't appear indicate a kernel bug.  The
+expected behavior is to fail the command, which the code does.
+
+Here's a reproducer that works in QEMU when /dev/sg0 refers to a disk of
+the default type ("82371SB PIIX3 IDE"):
+
+    #include <fcntl.h>
+    #include <unistd.h>
+
+    int main()
+    {
+            char buf[42] = { [36] = 0x8 /* READ_6 */ };
+
+            write(open("/dev/sg0", O_RDWR), buf, sizeof(buf));
+    }
