2015-11-12X.509: Fix the time validation [ver #2]David Howells
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 -----BEGIN CERTIFICATE----- MIIDbjCCAlagAwIBAgIJAN/lUld+VR4hMA0GCSqGSIb3DQEBCwUAMCkxETAPBgNV BAoMCGxvY2FsLWNhMRQwEgYDVQQDDAtzaWduaW5nIGtleTAeFw0xNTA5MDEyMTMw MThaFw0xNjA4MzEyMTMwMThaMCkxETAPBgNVBAoMCGxvY2FsLWNhMRQwEgYDVQQD DAtzaWduaW5nIGtleTCCASIwDQYJKoZIhvcNAQEBBQADggEPADCCAQoCggEBANrn crcMfMeG67nagX4+m02Xk9rkmsMKI5XTUxbikROe7GSUVJ27sPVPZp4mgzoWlvhh jfK8CC/qhEhwep8Pgg4EJZyWOjhZb7R97ckGvLIoUC6IO3FC2ZnR7WtmWDgo2Jcj VlXwJdHhKU1VZwulh81O61N8IBKqz2r/kDhIWiicUCUkI/Do/RMRfKAoDBcSh86m gOeIAGfq62vbiZhVsX5dOE8Oo2TK5weAvwUIOR7OuGBl5AqwFlPnXQolewiHzKry THg9e44HfzG4Mi6wUvcJxVaQT1h5SrKD779Z5+8+wf1JLaooetcEUArvWyuxCU59 qxA4lsTjBwl4cmEki+cCAwEAAaOBmDCBlTAMBgNVHRMEBTADAQH/MAsGA1UdDwQE AwIHgDAdBgNVHQ4EFgQUyND/eKUis7ep/hXMJ8iZMdUhI+IwWQYDVR0jBFIwUIAU yND/eKUis7ep/hXMJ8iZMdUhI+KhLaQrMCkxETAPBgNVBAoMCGxvY2FsLWNhMRQw EgYDVQQDDAtzaWduaW5nIGtleYIJAN/lUld+VR4hMA0GCSqGSIb3DQEBCwUAA4IB AQAMqm1N1yD5pimUELLhT5eO2lRdGUfTozljRxc7e2QT3RLk2TtGhg65JFFN6eml XS58AEPVcAsSLDlR6WpOpOLB2giM0+fV/eYFHHmh22yqTJl4YgkdUwyzPdCHNOZL hmSKeY9xliHb6PNrNWWtZwhYYvRaO2DX4GXOMR0Oa2O4vaYu6/qGlZOZv3U6qZLY wwHEJSrqeBDyMuwN+eANHpoSpiBzD77S4e+7hUDJnql4j6xzJ65+nWJ89fCrQypR 4sN5R3aGeIh3QAQUIKpHilwek0CtEaYERgc5m+jGyKSc1rezJW62hWRTaitOc+d5 G5hh+9YpnYcxQHEKnZ7rFNKJ -----END CERTIFICATE----- EOF If it works, it emit a key ID; if it fails, it should give a bad message error.

2015-11-11sd: Clear PS bit before Mode Select.Gabriel Krisman Bertazi
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.

2015-11-11scsi: pmcraid: replace struct timeval with ktime_get_real_seconds()Alison Schofield
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; Signed-off-by: Alison Schofield <amsfield22@gmail.com> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Martin K.

It is however, written to, using 'struct timeval' which has a 32-bit seconds field and whose value will overflow in year 2038.

2015-11-11mpt3sas: Single driver module which supports both SAS 2.0 & SAS 3.0 HBAsSreekanth Reddy
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.

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.

2015-11-11mpt2sas: Move Gen2 HBA's device registration to a separate fileSreekanth Reddy
1. Create a mpt2sas_module.c file for mpt2sas where GEN2 HBA devices register with PCI, SML, IOCTL subsystems. 2. Updated the Makefile to use the object files from mpt3sas folder. 3. Defined a compilation flag SCSI_MPT2SAS which can be used to not include those sections of code from mpt3sas driver which are not required for mpt2sas driver. 4. Inherited automatic diag buffer feature from mpt3sas driver.

Note that one of the patches included in this pull request is against arch/unicore32. I've included it here because I couldn't get a response from Guan Xuetao and I consider the change low-risk.
