scsi: ufs: qcom: Convert to use UFSHCD_QUIRK_CUSTOM_CRYPTO_PROFILE

By default the UFS core is responsible for initializing the
blk_crypto_profile, but Qualcomm platforms have their own way of
programming and evicting crypto keys.  So currently
ufs_hba_variant_ops::program_key is used to redirect control flow from
ufshcd_program_key().  This has worked until now, but it's a bit of a hack,
given that the key (and algorithm ID etc.) ends up being converted from
blk_crypto_key => ufs_crypto_cfg_entry => SCM call parameters, where the
intermediate ufs_crypto_cfg_entry step is unnecessary.  Taking a similar
approach with the upcoming wrapped key support, the implementation of which
is similarly platform-specific, would require adding four new methods to
ufs_hba_variant_ops, changing program_key to take the struct
blk_crypto_key, and adding a new UFSHCD_CAP_* flag to indicate support for
wrapped keys.

This patch takes a different approach.  It changes ufs-qcom to use the
existing UFSHCD_QUIRK_CUSTOM_CRYPTO_PROFILE which was recently added for
ufs-exynos.  This allows it to override the full blk_crypto_profile,
eliminating the need for the existing ufs_hba_variant_ops::program_key and
the hooks that would have been needed for wrapped key support.  It does
require a bit of duplicated code to read the crypto capability registers,
but it's worth the simplification in design with ufs-qcom and ufs-exynos
now using the same method to customize the crypto profile, and it makes it
much easier to add wrapped key support.

scsi: storvsc: Don't assume cpu_possible_mask is dense

Current code allocates the stor_chns array with size num_possible_cpus().
This code assumes cpu_possible_mask is dense, which is not true in the
general case per [1]. If cpu_possible_mask is sparse, the array might be
indexed by a value beyond the size of the array.

However, the configurations that Hyper-V provides to guest VMs on x86 and
ARM64 hardware, in combination with how architecture specific code assigns
Linux CPU numbers, *does* always produce a dense cpu_possible_mask.  So the
dense assumption is not currently causing failures. But for robustness
against future changes in how cpu_possible_mask is populated, update the
code to no longer assume dense.

The correct approach is to allocate and initialize the array using size
"nr_cpu_ids". While this leaves unused array entries corresponding to holes
in cpu_possible_mask, the holes are assumed to be minimal and hence the
amount of memory wasted by unused entries is minimal.

Here is the 2nd part in the sequel, watering down the scsi host lock
usage in the ufs driver. This work is motivated by a comment made by
Bart [1], of the abuse of the scsi host lock in the ufs driver.  Its
Precursor [2] removed the host lock around some of the host register
accesses.

This part replaces the scsi host lock by dedicated locks serializing
access to the clock gating and clock scaling members.

Changes compared to v4:
 - split patch 1 into 2 parts (Bart)
 - use scoped_guard() for the host_lock as well (Bart)
 - remove irrelevant comment and use lockdep_assert_held instead (Bart)
 - improve @lock documentation (Bart)

Changes compared to v3:
 - Keep the host lock when checking ufshcd_state (Bean)

Changes compared to v2:
 - Use clang-format to fix formating (Bart)
 - Use guard() in ufshcd_clkgate_enable_store (Bart)
 - Elaborate commit log (Bart)

9 months agostrscpy: write destination buffer only once
Linus Torvalds [Sun, 1 Dec 2024 17:23:33 +0000 (09:23 -0800)]
strscpy: write destination buffer only once

The point behind strscpy() was to once and for all avoid all the
problems with 'strncpy()' and later broken "fixed" versions like
strlcpy() that just made things worse.

So strscpy not only guarantees NUL-termination (unlike strncpy), it also
doesn't do unnecessary padding at the destination.  But at the same time
also avoids byte-at-a-time reads and writes by _allowing_ some extra NUL
writes - within the size, of course - so that the whole copy can be done
with word operations.

It is also stable in the face of a mutable source string: it explicitly
does not read the source buffer multiple times (so an implementation
using "strnlen()+memcpy()" would be wrong), and does not read the source
buffer past the size (like the mis-design that is strlcpy does).

Finally, the return value is designed to be simple and unambiguous: if
the string cannot be copied fully, it returns an actual negative error,
making error handling clearer and simpler (and the caller already knows
the size of the buffer).  Otherwise it returns the string length of the
result.

However, there was one final stability issue that can be important to
callers: the stability of the destination buffer.

In particular, the same way we shouldn't read the source buffer more
than once, we should avoid doing multiple writes to the destination
buffer: first writing a potentially non-terminated string, and then
terminating it with NUL at the end does not result in a stable result
buffer.

Yes, it gives the right result in the end, but if the rule for the
destination buffer was that it is _always_ NUL-terminated even when
accessed concurrently with updates, the final byte of the buffer needs
to always _stay_ as a NUL byte.

[ Note that "final byte is NUL" here is literally about the final byte
  in the destination array, not the terminating NUL at the end of the
  string itself. There is no attempt to try to make concurrent reads and
  writes give any kind of consistent string length or contents, but we
  do want to guarantee that there is always at least that final
  terminating NUL character at the end of the destination array if it
  existed before ]

This is relevant in the kernel for the tsk->comm[] array, for example.
Even without locking (for either readers or writers), we want to know
that while the buffer contents may be garbled, it is always a valid C
string and always has a NUL character at 'comm[TASK_COMM_LEN-1]' (and
never has any "out of thin air" data).

So avoid any "copy possibly non-terminated string, and terminate later"
behavior, and write the destination buffer only once.

tools/power turbostat: Consolidate graphics sysfs access

Currently, there is an inconsistency in how graphics sysfs knobs are
accessed: graphics residency sysfs knobs are opened and closed for each
read, while graphics frequency sysfs knobs are opened once and remain
open until turbostat exits. This inconsistency is confusing and adds
unnecessary code complexity.

Consolidate the access method by opening the sysfs files once and
reusing the file pointers for subsequent accesses. This approach
simplifies the code and ensures a consistent method for accessing
graphics sysfs knobs.

The graphics sysfs knobs are read-only, making the use of fflush()
before reading them redundant.

tools/power turbostat: Enhance platform divergence description

In various generations, platforms often share a majority of features,
diverging only in a few specific aspects. The current approach of using
hardcoded values in 'platform_features' structure fails to effectively
represent these divergences.

To improve the description of platform divergence:
1. Each newly introduced 'platform_features' structure must have a base,
   typically derived from the previous generation.
2. Platform feature values should be inherited from the base structure
   rather than being hardcoded.
This approach ensures a more accurate and maintainable representation of
platform-specific features across different generations.

Converts `adl_features` and `lnl_features` to follow this new scheme.
