| * crypto: marvell/octeontx - fix double free of ptrColin Ian King2020-04-031-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently in the case where eq->src != req->ds, the allocation of ptr is kfree'd at the end of the code block. However later on in the case where enc is not null any of the error return paths that return via the error handling return path end up performing an erroneous second kfree of ptr. Fix this by adding an error exit label error_free and only jump to this when ptr needs kfree'ing thus avoiding the double free issue.

NOTE: On its face value this commit decreased throughput numbers reported by dd if=/dev/hwrng of=/dev/null bs=1 count=100K [iflag=nonblock] by about 15%, however commits that enable prediction resistance and limit JR total size impact the performance so much and move the bottleneck such as to make this regression irrelevant. NOTE: On the bright side, this commit reduces RNG in kernel DMA buffer memory usage from 2 x RN_BUF_SIZE (~256K) to 32K.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our handling of ciphers with IV trailing the AAD was correct but overly complicated. Refactor to simplify and possibly save one DMA burst. This has the added bonus of behaving the same as the generic rfc4543 implementation for none compliants inputs where the IV in the iv field was not the same as the IV in the AAD. There should be no change in behaviour with correct inputs. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

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.
