      This commit broke WPA offload by unconditionally clearing the crypto
      modes for non-WEP connections. Drop that part of the patch.

      tpm: disable hwrng for fTPM on some AMD designs · f1324bbc
      Mario Limonciello authored
      AMD has issued an advisory indicating that having fTPM enabled in
      BIOS can cause "stuttering" in the OS.  This issue has been fixed
      in newer versions of the fTPM firmware, but it's up to system
      designers to decide whether to distribute it.
      
      This issue has existed for a while, but is more prevalent starting
      with kernel 6.1 because commit b006c439 ("hwrng: core - start
      hwrng kthread also for untrusted sources") started to use the fTPM
      for hwrng by default. However, all uses of /dev/hwrng result in
      unacceptable stuttering.
      
      So, simply disable registration of the defective hwrng when detecting
      these faulty fTPM versions.  As this is caused by faulty firmware, it
      is plausible that such a problem could also be reproduced by other TPM
      interactions, but this hasn't been shown by any user's testing or reports.
      
      It is hypothesized to be triggered more frequently by the use of the RNG
      because userspace software will fetch random numbers regularly.
      
      Intentionally continue to register other TPM functionality so that users
      that rely upon PCR measurements or any storage of data will still have
      access to it.  If it's found later that another TPM functionality is
      exacerbating this problem a module parameter it can be turned off entirely
      and a module parameter can be introduced to allow users who rely upon
      fTPM functionality to turn it on even though this problem is present.

      tpm/eventlog: Don't abort tpm_read_log on faulty ACPI address · 80a6c216
      Morten Linderud authored
      tpm_read_log_acpi() should return -ENODEV when no eventlog from the ACPI
      table is found. If the firmware vendor includes an invalid log address
      we are unable to map from the ACPI memory and tpm_read_log() returns -EIO
      which would abort discovery of the eventlog.
      
      Change the return value from -EIO to -ENODEV when acpi_os_map_iomem()
      fails to map the event log.
      
      The following hardware was used to test this issue:

         - rtl8723bs driver fixes for issues found by Hans in testing

        now in 6.3-rc1 we have a "real" wifi driver for one that includes
        support for many many more devices than this old driver did. So it's
        time to remove it as it is no longer needed. The maintainers of this
        driver all have acked its removal. Many thanks to them over the years
        for working to clean it up and keep it working while the real driver
        was being developed.

      cpumask: relax sanity checking constraints · e7304080
      Linus Torvalds authored
      The cpumask_check() was unnecessarily tight, and causes problems for the
      users of cpumask_next().
      
      We have a number of users that take the previous return value of one of
      the bit scanning functions and subtract one to keep it in "range".  But
      since the scanning functions end up returning up to 'small_cpumask_bits'
      instead of the tighter 'nr_cpumask_bits', the range really needs to be
      using that widened form.
      
      [ This "previous-1" behavior is also the reason we have all those
        comments about /* -1 is a legal arg here. */ and separate checks for
        that being ok.  So we could have just made "small_cpumask_bits-1"
        be a similar special "don't check this" value.
      
        Tetsuo Handa even suggested a patch that only does that for
        cpumask_next(), since that seems to be the only actual case that
        triggers, but that all makes it even _more_ magical and special. So
        just relax the check ]
      
      One example of this kind of pattern being the 'c_start()' function in
      arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on
      other architectures.
