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.

|

|
||||
Make ehci_process_itd return an error in case we didn't do any actual
|
||||
iso transfer because we've found no active transaction. That'll avoid
|
||||
ehci happily run in circles forever if the guest builds a loop out of
|
||||
idts.
|
||||
|

This is CVE-2015-8558.

Subject: [PATCH] net: vmxnet3: avoid memory leakage in activate_device
|
||||
|
||||
Vmxnet3 device emulator does not check if the device is active
|
||||
before activating it, also it did not free the transmit & receive
|
||||
buffers while deactivating the device, thus resulting in memory
|
||||
leakage on the host. This patch fixes both these issues to avoid
|
||||
host memory leakage.

Subject: [PATCH] ide: ahci: reset ncq object to unused on error
|
||||
|
||||
When processing NCQ commands, AHCI device emulation prepares a
|
||||
NCQ transfer object; To which an aio control block(aiocb) object
|
||||
is assigned in 'execute_ncq_command'. In case, when the NCQ
|
||||
command is invalid, the 'aiocb' object is not assigned, and NCQ
|
||||
transfer object is left as 'used'. This leads to a use after
|
||||
free kind of error in 'bdrv_aio_cancel_async' via 'ahci_reset_port'.
|
||||
Reset NCQ transfer object to 'unused' to avoid it.

Subject: [PATCH] i386: avoid null pointer dereference
|
||||
|
||||
Hello,
|
||||
|
||||
A null pointer dereference issue was reported by Mr Ling Liu, CC'd here. It
|
||||
occurs while doing I/O port write operations via hmp interface. In that,
|
||||
'current_cpu' remains null as it is not called from cpu_exec loop, which
|
||||
results in the said issue.
|
||||
|
||||
Below is a proposed (tested)patch to fix this issue; Does it look okay?
|
||||
|
||||
===

Subject: [PATCH] virtio-9p: use accessor to get thread_pool
|
||||
|
||||
The aio_context_new() function does not allocate a thread pool. This is
|
||||
deferred to the first call to the aio_get_thread_pool() accessor. It is
|
||||
hence forbidden to access the thread_pool field directly, as it may be
|
||||
NULL. The accessor *must* be used always.
