+Subject: [PATCH] ide: fix ATAPI command permissions
+
+We're a little too lenient with what we'll let an ATAPI drive handle.
+Clamp down on the IDE command execution table to remove CD_OK permissions
+from commands that are not and have never been ATAPI commands.
+
+For ATAPI command validity, please see:
+- ATA4 Section 6.5 ("PACKET Command feature set")
+- ATA8/ACS Section 4.3 ("The PACKET feature set")
+- ACS3 Section 4.3 ("The PACKET feature set")
+
+ACS3 has a historical command validity table in Table B.4
+("Historical Command Assignments") that can be referenced to find when
+a command was introduced, deprecated, obsoleted, etc.
+
+The only reference for ATAPI command validity is by checking that
+version's PACKET feature set section.
+
+ATAPI was introduced by T13 into ATA4, all commands retired prior to ATA4
+therefore are assumed to have never been ATAPI commands.
+
+Mandatory commands, as listed in ATA8-ACS3, are:
+
+- DEVICE RESET
+- EXECUTE DEVICE DIAGNOSTIC
+- IDENTIFY DEVICE
+- IDENTIFY PACKET DEVICE
+- NOP
+- PACKET
+- READ SECTOR(S)
+- SET FEATURES
+
+Optional commands as listed in ATA8-ACS3, are:
+
+- FLUSH CACHE
+- READ LOG DMA EXT
+- READ LOG EXT
+- WRITE LOG DMA EXT
+- WRITE LOG EXT
+
+All other commands are illegal to send to an ATAPI device and should
+be rejected by the device.
+
+CD_OK removal justifications:
+
+0x06 WIN_DSM              Defined in ACS2. Not valid for ATAPI.
+0x21 WIN_READ_ONCE        Retired in ATA5. Not ATAPI in ATA4.
+0x94 WIN_STANDBYNOW2      Retired in ATA4. Did not coexist with ATAPI.
+0x95 WIN_IDLEIMMEDIATE2   Retired in ATA4. Did not coexist with ATAPI.
+0x96 WIN_STANDBY2         Retired in ATA4. Did not coexist with ATAPI.
+0x97 WIN_SETIDLE2         Retired in ATA4. Did not coexist with ATAPI.
+0x98 WIN_CHECKPOWERMODE2  Retired in ATA4. Did not coexist with ATAPI.
+0x99 WIN_SLEEPNOW2        Retired in ATA4. Did not coexist with ATAPI.
+0xE0 WIN_STANDBYNOW1      Not part of ATAPI in ATA4, ACS or ACS3.
+0xE1 WIN_IDLEIMMDIATE     Not part of ATAPI in ATA4, ACS or ACS3.
+0xE2 WIN_STANDBY          Not part of ATAPI in ATA4, ACS or ACS3.
+0xE3 WIN_SETIDLE1         Not part of ATAPI in ATA4, ACS or ACS3.
+0xE4 WIN_CHECKPOWERMODE1  Not part of ATAPI in ATA4, ACS or ACS3.
+0xE5 WIN_SLEEPNOW1        Not part of ATAPI in ATA4, ACS or ACS3.
+0xF8 WIN_READ_NATIVE_MAX  Obsoleted in ACS3. Not ATAPI in ATA4 or ACS.
+
+This patch fixes a divide by zero fault that can be caused by sending
+the WIN_READ_NATIVE_MAX command to an ATAPI drive, which causes it to
+attempt to use zeroed CHS values to perform sector arithmetic.

+Subject: [PATCH 3/3] virtio-net: correctly drop truncated packets
+
+When packet is truncated during receiving, we drop the packets but
+neither discard the descriptor nor add and signal used
+descriptor. This will lead several issues:
+
+- sg mappings are leaked
+- rx will be stalled if a lots of packets were truncated
+
+In order to be consistent with vhost, fix by discarding the descriptor
