      pstore/ram: Avoid allocation and leak of platform data · 5631e857
      Kees Cook authored
      Yue Hu noticed that when parsing device tree the allocated platform data
      was never freed. Since it's not used beyond the function scope, this
      switches to using a stack variable instead.

      gcc-plugins: arm_ssp_per_task_plugin: fix for GCC 9+ · 2c88c742
      Ard Biesheuvel authored
      GCC 9 reworks the way the references to the stack canary are
      emitted, to prevent the value from being spilled to the stack
      before the final comparison in the epilogue, defeating the
      purpose, given that the spill slot is under control of the
      attacker that we are protecting ourselves from.
      
      Since our canary value address is obtained without accessing
      memory (as opposed to pre-v7 code that will obtain it from a
      literal pool), it is unlikely (although not guaranteed) that
      the compiler will spill the canary value in the same way, so
      let's just disable this improvement when building with GCC9+.

      fix int_sqrt64() for very large numbers · fbfaf851
      Florian La Roche authored
      If an input number x for int_sqrt64() has the highest bit set, then
      fls64(x) is 64.  (1UL << 64) is an overflow and breaks the algorithm.
      
      Subtracting 1 is a better guess for the initial value of m anyway and
      that's what also done in int_sqrt() implicitly [*].
      
      [*] Note how int_sqrt() uses __fls() with two underscores, which already
          returns the proper raw bit number.
      
          In contrast, int_sqrt64() used fls64(), and that returns bit numbers
          illogically starting at 1, because of error handling for the "no
          bits set" case. Will points out that he bug probably is due to a
          copy-and-paste error from the regular int_sqrt() case.

      x86: uaccess: Inhibit speculation past access_ok() in user_access_begin() · 6e693b3f
      Will Deacon authored
      Commit 594cc251 ("make 'user_access_begin()' do 'access_ok()'")
      makes the access_ok() check part of the user_access_begin() preceding a
      series of 'unsafe' accesses.  This has the desirable effect of ensuring
      that all 'unsafe' accesses have been range-checked, without having to
      pick through all of the callsites to verify whether the appropriate
      checking has been made.
      
      However, the consolidated range check does not inhibit speculation, so
      it is still up to the caller to ensure that they are not susceptible to
      any speculative side-channel attacks for user addresses that ultimately
      fail the access_ok() check.
      
      This is an oversight, so use __uaccess_begin_nospec() to ensure that
      speculation is inhibited until the access_ok() check has passed.
