2019-11-07Windows Driver: Fix strange crashes caused by probably by APC queue issues ↵Mounir IDRASSI1-80/+225
from calls to IoBuildDeviceIoControlRequest and ZwCreate (cf https://www.osr.com/blog/2018/02/14/beware-iobuilddeviceiocontrolrequest/)
2019-03-03Windows Driver: Add IOCTL code to query RAM encryption status in VeraCrypt ↵Mounir IDRASSI1-0/+11
driver
2019-03-01Windows Driver: Enable RAM encryption only after its security parameters ↵Mounir IDRASSI1-6/+5
were created
2019-03-01Windows: use specific order for EFI boot arguments memory regions that ↵Mounir IDRASSI1-1/+41
matches the one used by EFI bootloader.
2019-03-01Windows: Implement RAM encryption for keys on 64-bit machines using ChaCha12 ↵Mounir IDRASSI1-1/+22
cipher and t1ha non-cryptographic fast hash (https://github.com/leo-yuriev/t1ha)
2019-02-12Windows: Use Hardware RNG based on CPU timing jitter "Jitterentropy" by ↵Mounir IDRASSI1-1/+15
Stephan Mueller as a good alternative to RDRAND (http://www.chronox.de/jent.html, smueller@chronox.de)
2019-02-08Windows: Add implementation of ChaCha20 based random generator. Use it for ↵Mounir IDRASSI1-0/+60
driver need of random bytes (currently only wipe bytes but more to come later).
2019-02-08Windows: Add option to enable use of CPU RDRAND/RDSEED as source of entropy ↵Mounir IDRASSI1-0/+1
which is now disabled by default
2019-01-28Windows Driver: force the input size for some IOCTLs to have a fixed valueMounir IDRASSI1-2/+28
2019-01-26Windows: Add a build configuration containing EFI bootloader signed with ↵Mounir IDRASSI1-1/+1
custom SecureBoot key instead
2019-01-14Windows: Implement feature that enables clearing of encryption keys when a ↵Mounir IDRASSI1-0/+7
new device is inserted. Better implementation for update of EFI bootloader without usage of drive letters (this can fix random issues encountered during Windows upgrade).
2019-01-09Windows Security: Add new entry point in driver that allows emergency ↵Mounir IDRASSI1-0/+5
clearing of all encryption keys from memory. This entry point requires administrative privileges and it will caused BSDO when system encryption is active. It can be useful for example to applications that monitors physical access to the machine and which need to erase sensitive key material from RAM when unauthorized access is detected.
2018-12-19Windows Driver: Don't interact with the volume's filesystem if mount manager ↵Mounir IDRASSI1-1/+1
integration is disabled
2018-12-19Windows: Add mount option that allows mounting a volume without attaching it ↵Mounir IDRASSI1-9/+11
to the specified drive letter. This is useful in situation where Windows has issue with the filesystem (e.g. ReFS on Windows 10 1809) and we need to use third party software to be able to use the filesystem under Windows through low level VeraCrypt virtual device (e.g. \Device\VeraCryptVolumeX).
2018-10-10Windows Driver: fix regression that was causing BSOD.Mounir IDRASSI1-1/+1
2018-10-10Windows Driver: replace system functions ↵Mounir IDRASSI1-9/+41
RtlUpcaseUnicodeChar/RtlUnalignedStringCchLengthW by our own code for better clarity
2018-09-21Windows driver: add extra check for data read in TC_IOCTL_OPEN_TEST handlingMounir IDRASSI1-1/+31
2018-09-21Windows: fix low severity vulnerability in driver that allowed reading 3 ↵Mounir IDRASSI1-49/+82
bytes of kernel stack memory (with a rare possibility of 25 additional bytes). Reported by Tim Harrison.
2018-09-01Windows: extended Windows defragmenter workaround to Windows 8.1Mounir IDRASSI1-3/+3
2018-08-24Windows: implement a driver configuration option to explicitly allow ↵Mounir IDRASSI1-1/+3
defragmenting non-système disques by Windows built-in defragmenter tool.
2018-08-18Windows: Implement workaround on Windows 10 to make VeraCrypt encrypted ↵Mounir IDRASSI1-5/+21
disks visible to Windows defragmenter
2018-08-15WIndows driver: add check for failed memory allocationMounir IDRASSI1-8/+11
2018-03-05Windows: Add option to block TRIM command on system encryption SSD drives.Mounir IDRASSI1-0/+4
2018-03-04Windows: Implement TRIM support for non-system SSD partitions/drives and add ↵Mounir IDRASSI1-32/+290
driver option to enable it (TRIM is disabled by default for non-system SSD partitions/drives)
2017-07-27Windows driver: correctly handle IOCTL_DISK_GET_DRIVE_GEOMETRY_EX to fix ↵Mounir IDRASSI1-29/+151
issues with some disks. Implement IOCTL_STORAGE_GET_MEDIA_TYPES_EX.
2017-07-23Windows Driver: make IOCTL_DISK_GET_DRIVE_GEOMETRY_EX support optional. Make ↵Mounir IDRASSI1-15/+19
disk size equal to partition size to avoid compatibility issues with existing software.
2017-07-23Windows Driver: add legacy handling for ↵Mounir IDRASSI1-23/+42
IOCTL_DISK_GET_DRIVE_LAYOUT_EX/IOCTL_DISK_GET_DRIVE_LAYOUT IOCTLs to fix issues with faulty applications and drivers that don't handle them correctly.
2017-07-20Windows driver: only activate newly supported IOCTLs if the option to enable ↵Mounir IDRASSI1-43/+83
extended IOCTLs is enabled in VeraCrypt driver settings.
2017-07-20Windows driver: fix IOCTL_DISK_GET_DRIVE_LAYOUT and ↵Mounir IDRASSI1-2/+2
IOCTL_DISK_GET_DRIVE_LAYOUT_EX output by using setting PartitionCount to 4 instead of 1 since this field must always be a multiple of 4 for MBR disks.
2017-07-05Windows Driver: correctly get KeRestoreExtendedProcessorState function pointer.Mounir IDRASSI1-4/+5
2017-07-04Windows: correctly handle SEH exceptions during self-tests in order to ↵Mounir IDRASSI1-1/+10
disable CPU extended features in such case.
2017-07-04Windows Driver: correctly save and restore extended processor state when ↵Mounir IDRASSI1-0/+41
performing AVX operations on Windows 7 and later. Enhance readability of code handling save/restore of floating point state.
2017-06-23Update IDRIX copyright yearMounir IDRASSI1-1/+1
2017-06-10Windows Driver Security: Use enhanced protection of NX pool under Windows 8 ↵Mounir IDRASSI1-0/+10
and later.
2017-06-01Windows: fix high CPU usage when a favorite is configured to mount using ↵Mounir IDRASSI1-22/+31
VolumeID when its host device is connected to the machine.
2017-05-28Windows Driver: enhance detection of FAT volumes.Mounir IDRASSI1-3/+5
2017-05-26Windows Driver: Correctly detect FAT volumes created on Linux in ↵Mounir IDRASSI1-0/+2
TC_IOCTL_OPEN_TEST FileSystem detection
2017-05-26Windows Driver: Add support for ReFS in TC_IOCTL_OPEN_TEST FileSystem detectionMounir IDRASSI1-1/+1
2017-05-25Windows: remove IOCTL_STORAGE_GET_DEVICE_NUMBER support until a real device ↵Mounir IDRASSI1-2/+3
is implemented.
2017-05-25Windows Driver: implement some extra IOCTLs. Add more traces for debugging.Mounir IDRASSI1-0/+112
2017-05-25Windows Driver: enhance implementation of IOCTL_STORAGE_QUERY_PROPERTYMounir IDRASSI1-9/+106
2017-05-25Windows Driver: remove unused variable.Mounir IDRASSI1-1/+0
2017-05-21Windows Driver: Support new IOCTLS and correct implementation of existing ↵Mounir IDRASSI1-3/+111
ones to solve Windows 10 compatibility issues.
2017-05-21Windows Driver: fix bug in new IOCTL VC_IOCTL_GET_DRIVE_GEOMETRY_EXMounir IDRASSI1-2/+0
2017-05-17Windows: use IOCTL_DISK_GET_DRIVE_GEOMETRY_EX instead of the deprecated ↵Mounir IDRASSI1-3/+32
IOCTL_DISK_GET_DRIVE_GEOMETRY in order to get accurate disk size value.
2016-10-17Windows: Fix failure to access EFS data on VeraCrypt volumes under Windows ↵Mounir IDRASSI1-2/+11
10 but supporting undocumented IOCTL.
2016-08-15Windows Driver: Add extra traces and enable tracing in release build if ↵Mounir IDRASSI1-6/+29

2016-04-14Windows: Finalize implementation of the new volume ID mechanism. Use SHA-256 ↵Mounir IDRASSI1-7/+7
instead of SHA-512 to compute volume ID to reduce string size and make more convenient to use.
