tools lib traceevent kbuffer: Remove extra update to data pointer in PADDING

2015-05-06T20:03:52+00:00

commit c5e691928bf166ac03430e957038b60adba3cf6c upstream. When a event PADDING is hit (a deleted event that is still in the ring buffer), translate_data() sets the length of the padding and also updates the data pointer which is passed back to the caller. This is unneeded because the caller also updates the data pointer with the passed back length. translate_data() should not update the pointer, only set the length.

tools lib traceevent: Add support for IP address formats

2015-01-26T15:04:41+00:00

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

2014-11-24T19:01:44+00:00

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

2014-11-24T19:01:40+00:00

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

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

2014-06-19T16:18:37+00:00

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.

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

2014-06-19T16:18:25+00:00

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.
