Mathieu Desnoyers [Fri, 23 Jan 2015 16:29:00 +0000 (11:29 -0500)] 
Fix: deadlock between UST registry lock and consumer lock

Reorganize locking of ust registry and consumer socket communication.

commit ce34fcd0 "Fix: per-uid flush and ust registry locking" attempted
to fix locking related to the UST registry, but doing so introduced a
deadlock. The actual solution is to reverse the order in which the UST
registry and the consumer lock nest: the UST registry will now to
responsible for serializing the registry content, and the consumer lock
will only protect communication with the consumer, as it should. This
deals with a TODO in the code.

The reason why this was not done from the beginning is that there was
originally an intent to make sure the ust registry lock is not held for
a long time, thus not while communicating with the consumer daemon.
However, when live has been implemented, it required communication with
the consumer daemon while the ust registry is held anyway. Therefore,
there is not much point anymore in trying to make sure this lock is not
held across the communication with consumerd in push_metadata. This
allows us to greatly simplify locking of the UST registry.

Mathieu Desnoyers [Thu, 15 Jan 2015 22:24:27 +0000 (17:24 -0500)] 
Fix: grab more than one packet for snapshots

There are a few issues with snapshot size: when taking a snapshot
without specifying any "max size" (should be unlimited), only a single
packet from each stream is saved. We expect all stream available content
to be saved. There is a similar issue when a max size is specified.

Also, trying to make all streams save as much data has unexpected
corner-cases: for instance, if we have this configuration:
- kernel channels: 2 subbuffers of 1MB x 8 CPUs
- per-PID UST channels: 16 subbuffers of 4kB x 8 CPUs x 100 apps

would require the user to have a very large max size, since it would try
to fit (8 + (100 * 8)) * 1MB = 808MB of sub-buffers, else it would fail.
This issue here is using the largest subbuffer size as the criterion
applied to all channels.

We fix those issues by simplifying the algorithm used to calculate how
much data to grab. Rather than calculating the size to grab from each
stream, we calculate a number of packets to grab. It fails if we cannot
grab at least one packet from each stream in the session. Then checks if
it can grab 2 packets from each stream, and so on, until there is no
more space available (based on max size). This is not a perfect
solution, but has the merit of being simple to understand, and has no
(or few) unexpected corner-cases.

Mathieu Desnoyers [Thu, 15 Jan 2015 22:24:26 +0000 (17:24 -0500)] 
Fix: per-uid flush and ust registry locking

Commit c4b88406 "Fix: ust-app: per-PID app unregister vs tracing stop
races" introduces a regression for per-UID flush. It can be triggered by
the test_high_throughput_limits (root regression) test. For per-UID
tracing, we need to use the registry channel ID, not the per-application
channel ID, when asking the consumer daemon to flush.

When doing this fix, we notice that the locking rules of push_metadata()
are weird. A per-ust app session lock is protecting registry data, which
makes it impossible to call push_metadata from a ust session level (for
the entire session) in the case of per-UID tracing. Moreover, it's
unclear how holding a per-application lock can protect a registry shared
across applications in per-UID tracing. Therefore, we move all accesses
to the registry metadata_key and metadata_closed fields into the
registry lock critical section. We now only rely on RCU to ensure
existance of registry across push_metadata(), rather than relying on the
per-application session lock.

It also takes care of a documentation vs code mismatch: push_metadata()
documents that "The session lock MUST be acquired here before calling
this.", but in reality, it's the application session lock which is held
across those calls. Removing this requirement, and relying on RCU
instead, fixes this mismatch.

Fix: tests: don't use pidof to wait for test apps

Use the bash shell "wait" to wait for all background tasks rather than
the racy "pidof". Indeed, it's possible that applications have been
forked, but not executed yet, when pidof is done, which would therefore
miss applications. Using "wait" from the shell solves this.

If we want to be really strict, we should have sessiond, consumerd, and
relayd export a file containing their own PID, and wait for this instead
of using pidof. But this will be for another fix.

9 years agoFix: ust-app: per-PID app unregister vs tracing stop races
Mathieu Desnoyers [Mon, 5 Jan 2015 02:25:09 +0000 (21:25 -0500)] 
Fix: ust-app: per-PID app unregister vs tracing stop races

There are various races with UST application unregister performed
concurrently with tracing stop operation when tracing with per-pid
buffers. This randomly affects availability of data shortly after the
data pending check returns that no more data is available.

ust_app_stop_trace_all() iterates on all applications in the ust_app_ht
hash table to issue a flush on all buffers. This is needed to ensure
that the sub-buffers being written to are made available to the
consumer, for both data consumption, and for the data pending check.
Failure to execute the sub-buffer flush makes following data pending
check return that there is no data in the buffers too early, thus
resulting in an incomplete trace.

It is therefore important that an application flushes all its buffers
before it is removed from the ust_app_ht.

This is where ust_app_unregister() needs to be fixed. Note that
ust_app_unregister() executes concurrently with
ust_app_stop_trace_all(), only taking the per-session lock. The order of
flush vs hash table removal therefore matters:

We need to push the metadata before removing application from
ust_app_ht. We also need to issue a flush for all application buffers
before removing the application from ust_app_ht.

Once this is fixed, there is yet another race, this time in
ust_app_flush_trace() (now renamed ust_app_flush_session()). It is
caused by the use of ustctl_sock_flush_buffer() which asks the
application to perform the buffer flush. Unfortunately, if the
application vanishes (not reachable anymore), but its unregistration has
not yet been processed by sessiond, then ust_app_stop_trace_all() will
fail to flush the application buffers, because
ustctl_sock_flush_buffer() will fail.

This final issue is fixed by asking the consumer daemon to flush the
associated channel rather than relying on the application.

Fix: data pending: allow empty streams

There are cases where a stream can be completely empty (no packet to
write) with UST: for instance, if a traced application is either
preempted for a long time, terminated, or stopped, between reserve and
commit. This will make the consumer consider that this stream has no
data ready. If this situation occurs in the first sub-buffer of a
stream, this stream will have no data at all (0 bytes).

Therefore, we need to let the data pending check consider that no data
is pending in this situation, otherwise it can make the data pending
check always return that there is data pending.

10 years agoFix: UST subbuffers silently dropped on moderate trace traffic
Mathieu Desnoyers [Tue, 18 Nov 2014 16:33:23 +0000 (17:33 +0100)] 
Fix: UST subbuffers silently dropped on moderate trace traffic

Well, it looks like we really screwed up on this one.

lttng-tools commit 02b3d1769d5f8a33e4109b1e681141c9295dfda6 introduced
an important regression for lttng-ust tracing in the consumer daemon:
after reading a sub-buffer, a check has been added to see whether there
are more sub-buffers available to read, and if it is the case, it
ensures the wakeup pipe will be awakened again.

The issue lies in the use of ustctl_put_next_subbuf() in this check.
This acts as if the sub-buffer has been read, when in reality it has not
been read. It therefore trashes the data contained by this sub-buffer.

This check should use ustctl_put_subbuf(), which does not move the
consumer position.

This is a severe bug, and the fix needs to be applied to stable-2.6,
stable-2.5, and stable-2.4.

Fix: create/destroy a splice_pipe per stream

We had a per-thread splice_pipe (one for data and one for metadata), but
in case of error, we would end up filling the write side of the pipe and
never emptying it. This could lead to leaking data from one session to
the other, but also to stall the consumer trying to splice into a full
pipe.

Now we create a splice_pipe per-stream, so it is destroyed when the
session is destroyed.

Fix: check userspace perf counter name when looking up contexts

create_ust_app_channel_context() looks for a context's existance
in a channel before adding it. However, it only checks for
context types. This is valid for all context types except for
LTTNG_UST_CONTEXT_PERF_THREAD_COUNTER since multiple perf
thread counters may be enabled at the same time.

This fix ensures that the perf counter name is taken into
consideration when checking for a context's presence in a
channel.
