2020-03-12crypto: ccp - use file mode for sev ioctl permissionsConnor Kuehl1-16/+17
Instead of using CAP_SYS_ADMIN which is restricted to the root user, check the file mode for write permissions before executing commands that can affect the platform. This allows for more fine-grained access control to the SEV ioctl interface. This would allow a SEV-only user or group the ability to administer the platform without requiring them to be root or granting them overly powerful permissions. For example: chown root:root /dev/sev chmod 600 /dev/sev setfacl -m g:sev:r /dev/sev setfacl -m g:sev-admin:rw /dev/sev In this instance, members of the "sev-admin" group have the ability to perform all ioctl calls (including the ones that modify platform state). Members of the "sev" group only have access to the ioctls that do not modify the platform state. This also makes opening "/dev/sev" more consistent with how file descriptors are usually handled. By only checking for CAP_SYS_ADMIN, the file descriptor could be opened read-only but could still execute ioctls that modify the platform state. This patch enforces that the file descriptor is opened with write privileges if it is going to be used to modify the platform state. This flexibility is completely opt-in, and if it is not desirable by the administrator then they do not need to give anyone else access to /dev/sev.

Since updating req->iv (for chaining) is not required, modify skcipher descriptors to set the FINAL bit for chacha20. [Note that for skcipher decryption we know that ctx1_iv_off is 0, which allows for an optimization by not checking algorithm type, since append_dec_op1() sets FINAL bit for all algorithms except AES.] Also drop the descriptor operations that save the IV.

2020-03-06crypto: Replace zero-length array with flexible-array memberGustavo A. R. Silva9-13/+13
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.
