Linus Torvalds ff2ae607c6 SPDX patches for 5.7-rc1.
Here are 3 SPDX patches for 5.7-rc1.
 
 One fixes up the SPDX tag for a single driver, while the other two go
 through the tree and add SPDX tags for all of the .gitignore files as
 needed.
 
 Nothing too complex, but you will get a merge conflict with your current
 tree, that should be trivial to handle (one file modified by two things,
 one file deleted.)
 
 All 3 of these have been in linux-next for a while, with no reported
 issues other than the merge conflict.

Colin Ian King 755bddd1e4 crypto: marvell/octeontx - fix double free of ptr
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.

Ayush Sawal ad59ddd02d Crypto: chelsio - Fixes a hang issue during driver registration
This issue occurs only when multiadapters are present. Hang
happens because assign_chcr_device returns u_ctx pointer of
adapter which is not yet initialized as for this adapter cxgb_up
is not been called yet.

The last_dev pointer is used to determine u_ctx pointer and it
is initialized two times in chcr_uld_add in chcr_dev_add respectively.

The fix here is don't initialize the last_dev pointer during
chcr_uld_add. Only assign to value to it when the adapter's
initialization is completed i.e in chcr_dev_add.

Andrey Smirnov 2c5e88dc90 crypto: caam - simplify RNG implementation
Rework CAAM RNG implementation as follows:

- Make use of the fact that HWRNG supports partial reads and will
handle such cases gracefully by removing recursion in caam_read()

- Convert blocking caam_read() codepath to do a single blocking job
read directly into requested buffer, bypassing any intermediary
buffers

- Convert async caam_read() codepath into a simple single
reader/single writer FIFO use-case, thus simplifying concurrency
handling and delegating buffer read/write position management to KFIFO
subsystem.

- Leverage the same low level RNG data extraction code for both async
and blocking caam_read() scenarios, get rid of the shared job
descriptor and make non-shared one as a simple as possible (just
HEADER + ALGORITHM OPERATION + FIFO STORE)

- Split private context from DMA related memory, so that the former
could be allocated without GFP_DMA.

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.

Leverage devres to get rid of code storing global context as well as
init_done flag.

Original code also has a circular deallocation dependency where
unregister_algs() -> caam_rng_exit() -> caam_jr_free() chain would
only happen if all of JRs were freed. Fix this by moving
caam_rng_exit() outside of unregister_algs() and doing it specifically
for JR that instantiated HWRNG.

Kernel TLS forms TLS header in kernel during encryption and removes
while decryption before giving packet back to user application. The
similar logic is introduced in chtls code as well.

v1->v2:
- tls_proccess_cmsg() uses tls_handle_open_record() which is not required
  in TOE-TLS. Don't mix TOE with other TLS types.

This has the added bonus of behaving the same as the generic

Connor Kuehl b610281358 crypto: ccp - use file mode for sev ioctl permissions
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.
