* In the upcoming Boost 1.89.0 release, the Boost.System stub
library introduced back in 1.69 has been removed, which causes
a CMake error when system component is required.
The component can just be dropped cryfs has a minimum of Boost
1.84.0.

Backwards Compatibility
* Filesystems created with CryFS 0.11.x and CryFS 1.0.0 are fully
compatible with each other. The storage format hasn't changed.
* This means filesystems created with 0.10.x or 0.11.x can be
mounted without requiring a migration.
* Filesystems created with 1.0.0 or 0.11.x can be mounted by
CryFS 0.10.x, but only if you configure it to use a cipher
supported by CryFS 0.10.x, e.g. AES-256-GCM. The new default,
XChaCha20-Poly1305, is not supported by CryFS 0.10.x.
Fixes/Improvements
* Added a man page for cryfs-unmount
* Fixed small inaccuracy in calculation of free space in statvfs
* Fix an issue when using -o atime mount options
- Remove 38849c22aa34c5fad10091e066a520dd831462b3.patch
(merged upstream)
OBS-URL: https://build.opensuse.org/package/show/security:privacy/cryfs?expand=0&rev=33
- Update to v0.11.2:
* Time to mount a file system was very long because the build
didn't correctly use OpenMP. This is now fixed and file systems
should open faster again.
* Fix building of the range-v3 dependency. The conan remote URL
for this dependency changed and we have to use the new URL.
* Update to CryptoPP 8.6. This fixes a rare bug where
CryptoPP 8.5 encrypts data wrongly.
* cryfs-unmount correctly unmounts paths that contain spaces.
* Updated to DokanY 1.2.2.1001.

- Update to upstream version 0.11.0
* Backwards Compatibility:
- Filesystems created with CryFS 0.10.x can be mounted without
requiring a migration.
- Filesystems created with CryFS 0.11.x can be mounted by CryFS
0.10.x if you configure it to use a cipher supported by CryFS
0.10.x, e.g. AES-256-GCM. The new default, XChaCha20-Poly1305,
is not supported by CryFS 0.10.x.
* Security:
- Added the XChaCha20-Poly1305 encryption cipher. For new
filesystems, this will be the default, but you're still able
to create a filesystem with the previous default of AES-256-GCM
by saying "no" to the "use default settings?" question when
creating the file system. Also, old filesystems will not be
automatically converted and will keep using AES-256-GCM.
XChaCha20-Poly1305 is significantly slower than AES-256-GCM
on modern CPUs, but it is more secure for large filesystems
(>64GB).
For AES-256-GCM, it is recommended to encrypt at most 2^32
blocks, which at the CryFS default block size of 16KB would
be 64GB. The more the filesystem grows above that, the more
likely it gets that a nonce gets reused and the two
corresponding blocks become decryptable by an adversary.
Other blocks would not be affected, but an adversary being
able to access those two blocks (i.e. 64KB of the stored data)
is bad enough. See Section 8.3 in
https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication800-38d.pdf
XChaCha20-Poly1305 does not suffer from this constraint and
stays secure even if the filesystem gets very large.
* New platforms:
- CryFS now works on devices with Apple M1 silicon
* Build changes:
- Switch to Conan package manager
- Allow an easy way to modify how the dependencies are found.
This is mostly helpful for package maintainers. See "Using
local dependencies" in the README.
- Build with macFUSE instead of osxfuse on OSX
- Now requires CMake 3.10 or later, and GCC 7 or later,
or Clang 7 or later
- Fix a build issue on Gentoo systems
- Fix a build issue when building with boost 1.77
* Improvements:
- Display the file system configuration when mounting a file system
- Now shows a better error message when failing to load the config
file that distinguishes between "wrong password" and "config file
not found".
* New features:
- Add support for atime mount options (noatime, strictatime,
relatime, atime, nodiratime).
- The new default is now noatime (in 0.10.x is was relatime).
Noatime reduces the amount of writes necessary and with that
reduces the probability of synchronization conflicts, and the
probability of corrupted file systems if a power outage
happens while writing.
- Add an --immediate flag to cryfs-unmount that tries to unmount
immediately and doesn't wait for processes to release their
locks on the file system.
- Add a --create-missing-basedir and --create-missing-mountpoint
flag to create the base directory and mount directory respectively,
if they don't exist, skipping the confirmation prompt.
* Other:
- Updated to spdlog 1.8.5
- Updated to ranges-v3 0.11.0
- Updated to boost 1.75
- Updated to crypto++ 8.5
* Clean up spec file

- Update to upstream version 0.10.0, selected changes are:
* Integrity checks ensure you notice when someone modifies your file system.
* File system nodes (files, directories, symlinks) store a parent
pointer to the directory that contains them. This information can
be used in later versions to resolve some synchronization conflicts.
* Allow mounting using system mount tool and /etc/fstab
* Performance improvements
* Use relatime instead of strictatime (further performance improvement)
* cryfs-unmount tool to unmount filesystems-
