David Howells cc25b994ac X.509: Fix the time validation [ver #2]
This fixes CVE-2015-5327.  It affects kernels from 4.3-rc1 onwards.

Fix the X.509 time validation to use month number-1 when looking up the
number of days in that month.  Also put the month number validation before
doing the lookup so as not to risk overrunning the array.

This can be tested by doing the following:

cat <<EOF | openssl x509 -outform DER | keyctl padd asymmetric "" @s

I have two fixes for HV KVM which I would like to have included in

the host is configured for static 2-way micro-threading mode."

Gabriel Krisman Bertazi 2c5d16d6a9 sd: Clear PS bit before Mode Select.
According to SPC-4, in a Mode Select, the PS bit in Mode Pages is
reserved and must be set to 0 by the driver.  In the sd implementation,
function cache_type_store does a Mode Sense, which might set the PS bit
on the read buffer, followed by a Mode Select, which receives the same
buffer, without explicitly clearing the PS bit.  So, in cases where
target supports saving the Mode Page to a non-volatile location, we end
up doing a Mode Select with the PS bit set, which could cause an illegal
request error if the target is checking this.

This was observed on a new firmware change, which was subsequently
reverted, but this changes sd.c to be more compliant with SPC-4.

This patch clears the PS bit in the buffer returned by Mode Select,
right before it is used in the Mode Select command.

There is a static checker warning here because "bytes" is controlled by
the user and we cap the upper bound with min() but allow negatives.
Negative bytes will result in some nasty warning messages but are not
super harmful.  Anyway, no one needs negative bytes so let's just check
for it and return NULL.

Alison Schofield 9c9bd593f3 scsi: pmcraid: replace struct timeval with ktime_get_real_seconds()
Replace the use of struct timeval and do_gettimeofday() with
64 bit ktime_get_real_seconds. Prevents 32-bit type overflow
in year 2038 on 32-bit systems.

Driver was using the seconds portion of struct timeval (.tv_secs)
to pass a millseconds timestamp to the firmware. This change maintains
that same behavior using ktime_get_real_seconds.

The structure used to pass the timestamp to firmware is 48 bits and
works fine as long as the top 16 bits are zero and they will be zero
for a long time..ie. thousands of years.

Alternative Change:  Add sub second granularity to timestamp

As noted above, the driver only used the seconds portion of timeval,
ignores the microseconds portion, and by multiplying by 1000 effectively
does a <<10 and always writes zero into timestamp[0].

The alternative change would pass all the bits to the firmware:

        struct timespec64 ts;

        ktime_get_real_ts64(&ts);
        timestamp = ts.tv_sec * MSEC_PER_SEC + ts.tv_nsec / NSEC_PER_MSEC;

struct mvumi_hs_page2 stores a "seconds_since1970" field which is of
type u64. It is however, written to, using 'struct timeval' which has
a 32-bit seconds field and whose value will overflow in year 2038.
This patch uses ktime_get_real_seconds() instead since it provides a
64-bit seconds value, which is 2038 safe.

Vitaly Kuznetsov a4cf30e15c scsi_scan: don't dump trace when scsi_prep_async_scan() is called twice
The only user of scsi_prep_async_scan() is scsi_scan_host() and it
handles the situation correctly. Move 'called twice' reporting to debug
level as well.

The issue is observed on Hyper-V: on any device add/remove event storvsc
driver calls scsi_scan_host() and in case previous scan is still running
we get the message and stack dump on console.

Sreekanth Reddy c84b06a48c mpt3sas: Single driver module which supports both SAS 2.0 & SAS 3.0 HBAs
Modified the mpt3sas driver to have a single driver module which
supports both SAS 2.0 & SAS 3.0 HBA devices.

* Added SAS 2.0 HBA device IDs to the mpt3sas_pci_table pci table.

* Created two separate SCSI host templates for SAS2 and SAS3 HBAs so
  that, during the driver load time driver can use corresponding host
  template(based the pci device ID) while registering a scsi host
  adapter instance for that pci device.

* Registered two IOCTL devices, mpt2ctl is for SAS2 HBAs & mpt3ctl for
  SAS3 HBAs. Also updated the code to make sure that mpt2ctl device
  processes only those ioctl cmds issued for the SAS2 HBAs and mpt3ctl
  device processes only those ioctl cmds issued for the SAS3 HBAs.

* Added separate indexing for SAS2 and SAS3 HBAs.

* Replaced compile time check 'MPT2SAS_SCSI' to run time check
  'hba_mpi_version_belonged' whereever needed.

* Aliased this merged driver to mpt2sas using MODULE_ALIAS.

* Moved global varaible 'driver_name' to per adapter instance variable.

* Created two raid function template and used corresponding raid
  function templates based on the run time check
  'hba_mpi_version_belonged'.

* Moved mpt2sas_warpdrive.c file from mpt2sas to mpt3sas folder and
  renamed it as mpt3sas_warpdrive.c.

* Also renamed the functions in mpt3sas_warpdrive.c file to follow
  current driver function name convention.

* Updated the Makefile to build mpt3sas_warpdrive.o file for these
  WarpDrive-specific functions.

* Also in function mpt3sas_setup_direct_io(), used sector_div() API
  instead of division operator (which gives compilation errors on 32 bit
  machines).

* Removed mpt2sas files, mpt2sas directory & mpt3sas_module.c file.

* Added module parameter 'hbas_to_enumerate' which permits using this
  merged driver as a legacy mpt2sas driver or as a legacy mpt3sas
  driver.

  Here are the available options for this module parameter:

   0 - Merged driver which enumerates both SAS 2.0 & SAS 3.0 HBAs
   1 - Acts as legacy mpt2sas driver, which enumerates only SAS 2.0 HBAs
   2 - Acts as legacy mpt3sas driver, which enumerates only SAS 3.0 HBAs

* Removed mpt2sas entries from SCSI's Kconfig and Makefile files.

We need a way to make sure threads can't delete them out from under each

Additionally, we cannot iterate over the sas_device_list without holding

deleted as we iterate. This patch refactors _scsih_probe_sas() to use
the sas_device_list in a safe way.

Sreekanth Reddy 422630955e mpt3sas: sysfs attribute to report Backup Rail Monitor Status
A new sysfs shost attribute called "BMR_status" is implemented to report
Backup Rail Monitor status.

This attribute is located in:

        /sys/class/scsi_host/host#/BMR_status

When reading this adapter attribute, the driver will output the state of
GPIO[24]. It returns "0" if BMR is healthy and "1" for failure.

If it returns an empty string then it means that there was an error
while obtaining the BMR status. Check dmesg for what error has occurred.

This sysfs shost attribute is mainly for WarpDrive controllers.

This commit is a port of 6c265660c2 ("mpt2sas: Provide sysfs attribute
to report Backup Rail Monitor Status").

Currently there is a logging level option provided for each of our

Only when this option is enabled will the functions which display the

As we are merging the both drivers we can no longer provide this
configuration option. Remove the SCSI_MPTXSAS_LOGGING entry from Kconfig
and unconditionally enable logging (by removing the #ifdef
CONFIG_SCSI_MPT3SAS_LOGGING preprocessor check conditions) so that all

Brian Norris a61ae81a19 mtd: nand: drop unnecessary partition parser data
All of these drivers set up a parser data struct just to communicate DT
partition data. This field has been deprecated and is instead supported
by telling nand_scan_ident() about the 'flash_node'.

This patch:
 * sets chip->flash_node for those drivers that didn't already (but used
   OF partitioning)
 * drops the parser data
 * switches to the simpler mtd_device_register() where possible, now
   that we've eliminated one of the auxiliary parameters

Now that we've assigned chip->flash_node for these drivers, we can
probably rely on nand_dt_init() to do more of the DT parsing for us, but
for now, I don't want to fiddle with each of these drivers. The parsing
is done in duplicate for now on some drivers. I don't think this should
break things. (Famous last words.)
