tools lib traceevent: Add support for IP address formats

2015-01-26T15:04:41Z

Add helpers for the following kernel formats: %pi4 print an IPv4 address with leading zeros %pI4 print an IPv4 address without leading zeros %pi6 print an IPv6 address without colons %pI6 print an IPv6 address with colons %pI6c print an IPv6 address in compressed form with colons %pISpc print an IP address from a sockaddr Allows these formats to be used in tracepoints. Quite a bit of this is adapted from code in lib/vsprintf.c. v4: - fixed pI6c description in git commit message per Valdis' comment v3: - use of 'c' and 'p' requires 'I' v2: - pass ptr+1 to print_ip_arg per Namhyung's comments - added field length checks to sockaddr function Signed-off-by: David Ahern Acked-by: Steven Rostedt Cc: Jiri Olsa Cc: Namhyung Kim Link: http://lkml.kernel.org/r/1418955071-36241-1-git-send-email-dsahern@gmail.com Signed-off-by: Arnaldo Carvalho de Melo

scsi: add SPC-3 command definitions

2014-11-24T19:01:44Z

SPC-3 defines SERVICE ACTION IN(12), SERVICE_ACTION OUT(12), SERVICE ACTION OUT(16), and SERVICE ACTION BIDIRECTIONAL. And READ MEDIA SERIAL NUMBER has long since been deprecated. So update callers to refer to the new cdb name. Signed-off-by: Hannes Reinecke Tested-by: Robert Elliott Reviewed-by: Robert Elliott Signed-off-by: Christoph Hellwig

scsi: rename SERVICE_ACTION_IN to SERVICE_ACTION_IN_16

2014-11-24T19:01:40Z

SPC-3 defines SERVICE ACTION IN(12) and SERVICE ACTION IN(16). So rename SERVICE_ACTION_IN to SERVICE_ACTION_IN_16 to be consistent with SPC and to allow for better distinction. Signed-off-by: Hannes Reinecke Tested-by: Robert Elliott Reviewed-by: Robert Elliott Signed-off-by: Christoph Hellwig

tools lib traceevent: Fix a risk for doing free on uninitialized pointer

2014-06-27T09:14:47Z

Fix a risk of doing free on an uninitialized pointer. This was found using a static code analysis program called cppcheck.

tools lib traceevent: Clean up format of args in jbd2 plugin

2014-06-19T16:18:37Z

While synchronizing what's in trace-cmd vs what's in perf, I came across a change that was made when entering the jbd2 plugin into the tools/lib/traceevent directory. For example, one of the function prototypes went from: unsigned long long process_jbd2_dev_to_name(struct trace_seq *s, unsigned long long *args) to: static unsigned long long process_jbd2_dev_to_name(struct trace_seq *s, unsigned long long *args) I can understand the line break after the long long, but there's no reason to keep args on a separate line.

tools lib traceevent: Fix format in plugin_kvm

2014-06-19T16:18:33Z

The format field argument passed to the format in pevent_print_num_field() will be of type long long. That means that %ll must be used instead of %l.

2014-06-19T16:18:30Z

Fix several issues of kvm_nested_vmexit[_inject]: field width aren't supported with pevent_print, rip was printed twice/incorrectly, SVM ISA was hard-coded, we don't use ':' to separate field names.

tools lib traceevent: Add back in kvm plugins nested_vmexit events

2014-06-19T16:18:25Z

The nested vmexit events were removed from the backport from trace-cmd because they were considered buggy. They have since been updated in trace-cmd but are still missing from the traceevent library. Add back in the buggy version to be able to backport the fixes.
