      vsprintf: don't use 'restricted_pointer()' when not restricting · ef0010a3
      Linus Torvalds authored
      Instead, just fall back on the new '%p' behavior which hashes the
      pointer.
      
      Otherwise, '%pK' - that was intended to mark a pointer as restricted -
      just ends up leaking pointers that a normal '%p' wouldn't leak.  Which
      just make the whole thing pointless.
      
      I suspect we should actually get rid of '%pK' entirely, and make it just
      work as '%p' regardless, but this is the minimal obvious fix.  People
      who actually use 'kptr_restrict' should weigh in on which behavior they
      want.

      kallsyms: take advantage of the new '%px' format · 668533dc
      Linus Torvalds authored
      The conditional kallsym hex printing used a special fixed-width '%lx'
      output (KALLSYM_FMT) in preparation for the hashing of %p, but that
      series ended up adding a %px specifier to help with the conversions.
      
      Use it, and avoid the "print pointer as an unsigned long" code.

      Linus Torvalds authored
      Pull printk pointer hashing update from Tobin Harding:
       "Here is the patch set that implements hashing of printk specifier %p.
      
        First we have two clean up patches then we do the hashing. Hashing is
        done via the SipHash algorithm. The next patch adds printk specifier
        %px for printing pointers when we _really_ want to see the address i.e
        %px is functionally equivalent to %lx. Final patch in the set fixes
        KASAN since we break it by hashing %p.
      
        For the record here is the justification for the series:
      
          Currently there exist approximately 14 000 places in the Kernel
          where addresses are being printed using an unadorned %p. This
          potentially leaks sensitive information about the Kernel layout in
          memory. Many of these calls are stale, instead of fixing every call
          we hash the address by default before printing. We then add %px to
          provide a way to print the actual address. Although this is
          achievable using %lx, using %px will assist us if we ever want to
          change pointer printing behaviour. %px is more uniquely grep'able
          (there are already >50 000 uses of %lx).
      
          The added advantage of hashing %p is that security is now opt-out,
          if you _really_ want the address you have to work a little harder
          and use %px.
      
        This will of course break some users, forcing code printing needed
        addresses to be updated"
      
      [ I do expect this to be an annoyance, and a number of %px users to be
        added for debuggability. But nobody is willing to audit existing %p
        users for information leaks, and a number of places really only use
        the pointer as an object identifier rather than really 'I need the
        address'.
      
        IOW - sorry for the inconvenience, but it's the least inconvenient of
        the options.    - Linus ]

      It was a nice cleanup in theory, but as Nicolai Stange points out, we do
      need to make the page dirty for the copy-on-write case even when we
      didn't end up making it writable, since the dirty bit is what we use to
      check that we've gone through a COW cycle.

      vsprintf: add printk specifier %px · 7b1924a1
      Tobin C. Harding authored
      printk specifier %p now hashes all addresses before printing. Sometimes
      we need to see the actual unmodified address. This can be achieved using
      %lx but then we face the risk that if in future we want to change the
      way the Kernel handles printing of pointers we will have to grep through
      the already existent 50 000 %lx call sites. Let's add specifier %px as a
      clear, opt-in, way to print a pointer and maintain some level of
      isolation from all the other hex integer output within the Kernel.
      
      Add printk specifier %px to print the actual unmodified address.
