Fix: lttng-live discarded event count after inactivity

When a stream is inactive, the consumer produces fake indexes which are
beacons to let the viewer know a stream has not produced any data up to
a certain timestamp. These beacon are actually real packet indexes with
all the fields set to 0 except for the timestamp_end. Currently we keep
these beacons just like we keep real indexes. The problem is that when
we switch packet, we compare the events_discarded field in the index we
just received with the same field in the previous index. In the case
where a stream has been inactive, we have received inactivity beacons,
and set the discarded_event field to 0, so the difference with the next
real index might be wrong.

In fact, since the inactivity beacons are only used to push the
timestamp end of a stream, we don't need to keep them and we actually
need to keep most of the data from the real previous index. So we now
copy the entire prev_index into the cur_index when we receive an
inactivity beacon. We could refactor the code to avoid performing the
pointer swap of cur and prev indexes, but this implies a redesign of
much of the packet switching code which would affect other code paths.

7 years agoFix live-comm: merge TCP socket write-write sequence in a single write
Jonathan Rajotte [Mon, 24 Jul 2017 20:06:17 +0000 (16:06 -0400)] 
Fix live-comm: merge TCP socket write-write sequence in a single write

The live protocol implementation is often sending content
on TCP sockets in two separate writes. One to send a command header,
and the second one sending the command's payload. This was presumably
done under the assumption that it would not result in two separate
TCP packets being sent on the network (or that it would not matter).

Delayed ACK-induced delays were observed [1] on the second write of the
"write header, write payload" sequence and result in problematic
latency build-ups for live clients connected to moderately/highly
active sessions.

Fundamentaly, this problem arises due to the combination of Nagle's
algorithm and the delayed ACK mechanism which make write-write-read
sequences on TCP sockets problematic as near-constant latency is
expected when clients can keep-up with the event production rate.

In such a write-write-read sequence, the second write is held up until
the first write is acknowledged (TCP ACK). The solution implemented
by this patch bundles the writes into a single one [2].

8 years agodebug info: Call register_event_debug_infos for all events
Simon Marchi [Sun, 19 Jun 2016 15:14:29 +0000 (11:14 -0400)] 
debug info: Call register_event_debug_infos for all events

The register_event_debug_infos function is responsible for setting the
debug_info_src field of the struct definition_integer representing the
"ip" context field.  This pointer is used later to print the
source and binary location of the tracepoint.

Currently, it's not called for the events that have a special meaning
for the debug info analysis (statedump start, dlopen, bin_info, etc).
This means that for these events, the debug_info_src pointer keeps the
value of the previous event from that stream (since the ip field is in
stream event context, there is one instance per stream), which leads to
wrong information and/or crash.  A crash can happen when the debug info
structures are cleared because a statedump start is encountered.
debug_info_src becomes a stale pointer and babeltrace tries to print a
string in free memory.

The fix is to call register_event_debug_infos for all events, which will
always set debug_info_src properly.  The events used to do the debug
info analysis are still regular events and have their own location
information.

The trace in bug #1018 shows a crash caused by this issue.

Here's an example of wrong info from the same trace:

... lttng_ust_statedump:bin_info: { cpu_id = 1 }, { vpid = 28991, ip = 0x7FD26665657D, debug_info = { bin = "libX11.so.6.3.0+0x213fa" } }, ...
... lttng_ust_statedump:build_id: { cpu_id = 1 }, { vpid = 28991, ip = 0x7FD266656656, debug_info = { bin = "libX11.so.6.3.0+0x213fa" } }, ...

We can see that the ip values are different, but the debug info refers
to the same location, which is impossible.  Here's the result with this
patch applied.

... lttng_ust_statedump:bin_info: { cpu_id = 1 }, { vpid = 28991, ip = 0x7FD26665657D, debug_info = { bin = "liblttng-ust.so.0.0.0+0x3557d", func = "trace_bin_info_cb+0xfa" } }, ...
... lttng_ust_statedump:build_id: { cpu_id = 1 }, { vpid = 28991, ip = 0x7FD266656656, debug_info = { bin = "liblttng-ust.so.0.0.0+0x35656", func = "trace_build_id_cb+0xbc" } }, ...

which seems more reasonnable.

AC_CHECK_LIB function achieves its test by trying to link against the

requirements/flags that may differ between different targets.

Set the minimal version of elfutils to 0.154

elfutils 0.154 is required since it is the first release to
include commit 5479725 (dwarf_highpc: Handle DW_AT_high_pc being
a constant offset from DW_AT_low_pc).

This is fix is required to read DwARF information produced by
"modern" (post-2012) GCCs which make use of this DWARF4
capability when generating position independant code. The binaries
provided as part of the test suite make use of this feature. Hence,
tests will fail with older elfutils versions.
