      tracing: Add TRACE_ITER_PRINTK flag check in __trace_puts/__trace_bputs · f0160a5a
      zhangwei(Jovi) 提交于
      The TRACE_ITER_PRINTK check in __trace_puts/__trace_bputs is missing,
      so add it, to be consistent with __trace_printk/__trace_bprintk.
      Those functions are all called by the same function: trace_printk().

      tracing: Fix graph tracer with stack tracer on other archs · 5f8bf2d2
      Steven Rostedt (Red Hat) 提交于
      Running my ftrace tests on PowerPC, it failed the test that checks
      if function_graph tracer is affected by the stack tracer. It was.
      Looking into this, I found that the update_function_graph_func()
      must be called even if the trampoline function is not changed.
      This is because archs like PowerPC do not support ftrace_ops being
      passed by assembly and instead uses a helper function (what the
      trampoline function points to). Since this function is not changed
      even when multiple ftrace_ops are added to the code, the test that
      falls out before calling update_function_graph_func() will miss that
      the update must still be done.
      
      Call update_function_graph_function() for all calls to
      update_ftrace_function()

      tracing: Add ftrace_trace_stack into __trace_puts/__trace_bputs · 8abfb872
      zhangwei(Jovi) 提交于
      Currently trace option stacktrace is not applicable for
      trace_printk with constant string argument, the reason is
      in __trace_puts/__trace_bputs ftrace_trace_stack is missing.
      
      In contrast, when using trace_printk with non constant string
      argument(will call into __trace_printk/__trace_bprintk), then
      trace option stacktrace is workable, this inconstant result
      will confuses users a lot.

      ALSA: hda - Fix broken PM due to incomplete i915 initialization · 4da63c6f
      Takashi Iwai 提交于
      When the initialization of Intel HDMI controller fails due to missing
      i915 kernel symbols (e.g. HD-audio is built in while i915 is module),
      the driver discontinues the probe.  However, since the probe was done
      asynchronously, the driver object still remains, thus the relevant PM
      ops are still called at suspend/resume. This results in the bad access
      to the incomplete audio card object, eventually leads to Oops or stall
      at PM.
      
      This patch adds the missing checks of chip->init_failed flag at each
      PM callback in order to fix the problem above.

      When the module sends bursts of data, sometimes a deadlock happens in

      quickly enough.
      
      Remove the endless while loop in function put_rxbuf_data() which is
      called by the urb completion handler.
      If there isn't enough room in the tty buffer, discards all the data

      net/l2tp: don't fall back on UDP [get|set]sockopt · 3cf521f7
      Sasha Levin 提交于
      The l2tp [get|set]sockopt() code has fallen back to the UDP functions
      for socket option levels != SOL_PPPOL2TP since day one, but that has
      never actually worked, since the l2tp socket isn't an inet socket.
      
      As David Miller points out:
      
        "If we wanted this to work, it'd have to look up the tunnel and then
         use tunnel->sk, but I wonder how useful that would be"
      
      Since this can never have worked so nobody could possibly have depended
      on that functionality, just remove the broken code and return -EINVAL.

      net: ppp: don't call sk_chk_filter twice · 3916a319
      Christoph Schulz 提交于
      Commit 568f194e ("net: ppp: use
      sk_unattached_filter api") causes sk_chk_filter() to be called twice when
      setting a PPP pass or active filter. This applies to both the generic PPP
      subsystem implemented by drivers/net/ppp/ppp_generic.c and the ISDN PPP
      subsystem implemented by drivers/isdn/i4l/isdn_ppp.c. The first call is from
      within get_filter(). The second one is through the call chain
      
        ppp_ioctl() or isdn_ppp_ioctl()
        --> sk_unattached_filter_create()
            --> __sk_prepare_filter()
                --> sk_chk_filter()
      
      The first call from within get_filter() should be deleted as get_filter() is
      called just before calling sk_unattached_filter_create() later on, which
      eventually calls sk_chk_filter() anyway.
      
      For 3.15.x, this proposed change is a bugfix rather than a pure optimization as
      in that branch, sk_chk_filter() may replace filter codes by other codes which
      are not recognized when executing sk_chk_filter() a second time. So with
      3.15.x, if sk_chk_filter() is called twice, the second invocation may yield
      EINVAL (this depends on the filter codes found in the filter to be set, but
      because the replacement is done for frequently used codes, this is almost
      always the case). The net effect is that setting pass and/or active PPP filters
      does not work anymore, since sk_unattached_filter_create() always returns
      EINVAL due to the second call to sk_chk_filter(), regardless whether the filter
      was originally sane or not.
