-Subject: [PATCH] pcnet: force the buffer access to be in bounds during tx
-
-4096 is the maximum length per TMD and it is also currently the size of
-the relay buffer pcnet driver uses for sending the packet data to QEMU
-for further processing. With packet spanning multiple TMDs it can
-happen that the overall packet size will be bigger than sizeof(buffer),
-which results in memory corruption.
-
-Fix this by only allowing to queue maximum sizeof(buffer) bytes.
-
-This is CVE-2015-3209.
-
-[Fixed 3-space indentation to QEMU's 4-space coding standard.

-(POSIX.1-2008), so should be available on systems we care about.

-Subject: [PATCH] xen: properly gate host writes of modified PCI CFG contents
-
-The old logic didn't work as intended when an access spanned multiple
-fields (for example a 32-bit access to the location of the MSI Message
-Data field with the high 16 bits not being covered by any known field).
-Remove it and derive which fields not to write to from the accessed
-fields' emulation masks: When they're all ones, there's no point in
-doing any host write.
-
-This fixes a secondary issue at once: We obviously shouldn't make any
-host write attempt when already the host read failed.
-
-This is XSA-128.

-Subject: [PATCH] xen/MSI-X: limit error messages
-
-Limit error messages resulting from bad guest behavior to avoid allowing
-the guest to cause the control domain's disk to fill.
-
-The first message in pci_msix_write() can simply be deleted, as this
-is indeed bad guest behavior, but such out of bounds writes don't
-really need to be logged.
-
-The second one is more problematic, as there guest behavior may only
-appear to be wrong: For one, the old logic didn't take the mask-all bit
-into account. And then this shouldn't depend on host device state (i.e.
-the host may have masked the entry without the guest having done so).
-Plus these writes shouldn't be dropped even when an entry is unmasked.
-Instead, if they can't be made take effect right away, they should take
-effect on the next unmasking or enabling operation - the specification
-explicitly describes such caching behavior. Until we can validly drop
-the message (implementing such caching/latching behavior), issue the
-message just once per MSI-X table entry.
-
-Note that the log message in pci_msix_read() similar to the one being
-removed here is not an issue: "addr" being of unsigned type, and the
-maximum size of the MSI-X table being 32k, entry_nr simply can't be
-negative and hence the conditonal guarding issuing of the message will
-never be true.
-
-This is XSA-130.

-Subject: [PATCH] xen/MSI: don't open-code pass-through of enable bit
- modifications
-
-Without this the actual XSA-131 fix would cause the enable bit to not
-get set anymore (due to the write back getting suppressed there based
-on the OR of emu_mask, ro_mask, and res_mask).
-
-Note that the fiddling with the enable bit shouldn't really be done by
-qemu, but making this work right (via libxc and the hypervisor) will
-require more extensive changes, which can be postponed until after the
-security issue got addressed.
-
-This is a preparatory patch for XSA-131.

- config space handling
-
-This is just to avoid having to adjust that calculation later in

-
-Note that including ->ro_mask in get_throughable_mask()'s calculation
-is only an apparent (i.e. benign) behavioral change: For r/o fields it
-doesn't matter > whether they get passed through - either the same flag
-is also set in emu_mask (then there's no change at all) or the field is
-r/o in hardware (and hence a write won't change it anyway).

-Subject: [PATCH] xen/pt: mark all PCIe capability bits read-only
-
-xen_pt_emu_reg_pcie[]'s PCI_EXP_DEVCAP needs to cover all bits as read-
-only to avoid unintended write-back (just a precaution, the field ought
-to be read-only in hardware).
-
-This is a preparatory patch for XSA-131.

-Subject: [PATCH] xen/pt: mark reserved bits in PCI config space fields
-
-The adjustments are solely to make the subsequent patches work right
-(and hence make the patch set consistent), namely if permissive mode
-(introduced by the last patch) gets used (as both reserved registers
-and reserved fields must be similarly protected from guest access in
-default mode, but the guest should be allowed access to them in
-permissive mode).
-
-This is a preparatory patch for XSA-131.

+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.
