      tracepoint: Use struct_size() in kmalloc() · f0553dcb
      Gustavo A. R. Silva authored
      One of the more common cases of allocation size calculations is finding
      the size of a structure that has a zero-sized array at the end, along
      with memory for some number of elements for that array. For example:
      
      struct tp_probes {
      	...
              struct tracepoint_func probes[0];
      };
      
      instance = kmalloc(sizeof(sizeof(struct tp_probes) +
      			sizeof(struct tracepoint_func) * count, GFP_KERNEL);
      
      Instead of leaving these open-coded and prone to type mistakes, we can
      now use the new struct_size() helper:
      
      instance = kmalloc(struct_size(instance, probes, count) GFP_KERNEL);
      
      This code was detected with the help of Coccinelle.

      ring-buffer: Remove HAVE_64BIT_ALIGNED_ACCESS · 86b3de60
      Steven Rostedt (VMware) authored
      Commit c19fa94a ("Add HAVE_64BIT_ALIGNED_ACCESS") added the config for
      architectures that required 64bit aligned access for all 64bit words. As
      the ftrace ring buffer stores data on 4 byte alignment, this config option
      was used to force it to store data on 8 byte alignment to make sure the data
      being stored and written directly into the ring buffer was 8 byte aligned as
      it would cause issues trying to write an 8 byte word on a 4 not 8 byte
      aligned memory location.
      
      But with the removal of the metag architecture, which was the only
      architecture to use this, there is no architecture supported by Linux that
      requires 8 byte aligne access for all 8 byte words (4 byte alignment is good
      enough). Removing this config can simplify the code a bit.

      tracing: Add a check_val() check before updating cond_snapshot() track_val · 9b2ca371
      Tom Zanussi authored
      Without this check a snapshot is taken whenever a bucket's max is hit,
      rather than only when the global max is hit, as it should be.
      
      Before:
      
        In this example, we do a first run of the workload (cyclictest),
        examine the output, note the max ('triggering value') (347), then do
        a second run and note the max again.
      
        In this case, the max in the second run (39) is below the max in the
        first run, but since we haven't cleared the histogram, the first max
        is still in the histogram and is higher than any other max, so it
        should still be the max for the snapshot.  It isn't however - the
        value should still be 347 after the second run.

      tracing: Check keys for variable references in expressions too · c8d94a18
      Tom Zanussi authored
      There's an existing check for variable references in keys, but it
      doesn't go far enough.  It checks whether a key field is a variable
      reference but doesn't check whether it's an expression containing
      variable references, which can cause the same problems for callers.
      
      Use the existing field_has_hist_vars() function rather than a direct
      top-level flag check to catch all possible variable references.

      tracing: Prevent hist_field_var_ref() from accessing NULL tracing_map_elts · 55267c88
      Tom Zanussi authored
      hist_field_var_ref() is an implementation of hist_field_fn_t(), which
      can be called with a null tracing_map_elt elt param when assembling a
      key in event_hist_trigger().
      
      In the case of hist_field_var_ref() this doesn't make sense, because a
      variable can only be resolved by looking it up using an already
      assembled key i.e. a variable can't be used to assemble a key since
      the key is required in order to access the variable.
      
      Upper layers should prevent the user from constructing a key using a
      variable in the first place, but in case one slips through, it
      shouldn't cause a NULL pointer dereference.  Also if one does slip
      through, we want to know about it, so emit a one-time warning in that
      case.

      Pull perf tooling updates from Ingo Molnar:
       "perf.data:
      
         - Streaming compression of perf ring buffer into
           PERF_RECORD_COMPRESSED user space records, resulting in ~3-5x
           perf.data file size reduction on variety of tested workloads what
           saves storage space on larger server systems where perf.data size
           can easily reach several tens or even hundreds of GiBs, especially
           when profiling with DWARF-based stacks and tracing of context
           switches.
      
        perf record:
      
         - Improve -user-regs/intr-regs suggestions to overcome errors
      
        perf annotate:
      
         - Remove hist__account_cycles() from callback, speeding up branch
           processing (perf record -b)
      
        perf stat:
      
         - Add a 'percore' event qualifier, e.g.: -e
           cpu/event=0,umask=0x3,percore=1/, that sums up the event counts for
           both hardware threads in a core.
      
           We can already do this with --per-core, but it's often useful to do
           this together with other metrics that are collected per hardware
           thread.
      
           I.e. now its possible to do this per-event, and have it mixed with
           other events not aggregated by core.
      
        arm64:
      
         - Map Brahma-B53 CPUID to cortex-a53 events.
      
         - Add Cortex-A57 and Cortex-A72 events.
      
        csky:
      
         - Add DWARF register mappings for libdw, allowing --call-graph=dwarf
           to work on the C-SKY arch.
      
        x86:
      
         - Add support for recording and printing XMM registers, available,
           for instance, on Icelake.
      
         - Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON
           support. UPI replaced the Intel QuickPath Interconnect (QPI) in
           Xeon Skylake-SP.
      
        Intel PT:
      
         - Fix instructions sampling rate.
      
         - Timestamp fixes.
      
         - Improve exported-sql-viewer GUI, allowing, for instance, to
           copy'n'paste the trees, useful for e-mailing"
