 From 1132270594314acb2eed250f1690d5b10d0fb47c Mon Sep 17 00:00:00 2001
 From: John Kacur <jkacur@redhat.com>
 Date: Tue, 30 Jun 2015 14:30:47 +0200
 Subject: [PATCH] Various fixes for trace-cmd flightrecorder - systemd files
 1) Allow systemctl enable trace-cmd.service to start trace-cmd.service automatically at system boot
 2) Don't stop trace-cmd.service at system shutdown
 3) Don't stop trace-cmd.service at each kernel module loading
 4) Start trace-cmd.service before any normal services
 1) Allow systemctl enable trace-cmd.service to start trace-cmd.service automatically at system boot
 I added [Install] section in trace-cmd.service. This is necessary to
 make trace-cmd.service automatically get started at system
 boot. Without the [Install] section, systemctl enable
 trace-cmd.service fails as below:
  ~]# systemctl enable trace-cmd.service
  The unit files have no [Install] section. They are not meant to be enabled
  using systemctl.
  Possible reasons for having this kind of units are:
  1) A unit may be statically enabled by being symlinked from another unit's
     .wants/ or .requires/ directory.
  2) A unit's purpose may be to act as a helper for some other unit which has
     a requirement dependency on it.
  3) A unit may be started when needed via activation (socket, path, timer,
     D-Bus, udev, scripted systemctl call, ...).
 WantedBy=multi-user.target in trace-cmd.service means that
 trace-cmd.service is started if multi-user.target, traditional
 runlevel 3, is active.
 2) Don't stop trace-cmd.service at system shutdown
 In the current configuration, trace-cmd reset is executed when
 trace-cmd.service is stopped at system shutdown. Then, trace buffer is
 cleared. This could become a problem if system crash happens at system
 shutdown. Even if we get a crash dump at the crash during system
 shutdown, the crash dump doesn't contain useful trace data.
 To fix the issue, it's necessary to make trace-cmd.service not stop at
 system shutdown.
 To achieve this, I added DefaultDependencies=no into trace-cmd.service.
 To understand this, first you need to understand how systemd achieves
 system shutdown. Look at the description of shutdown.target in man 7
 systemd.special.
     shutdown.target
         A special target unit that terminates the services on
         system shutdown.
         Services that shall be terminated on system shutdown
         shall add Conflicts= dependencies to this unit for their
         service unit, which is implicitly done when
         DefaultDependencies=yes is set (the default).
 As this explains, systemd adds Conflicts=shutdown.target dependency to
 all the unit files by default. By this, if we shutdown system for
 example by systemctl poweroff, then all the currently active services
 with the default dependency get stopped when shutdown.target is pulled
 in.
 Thus, in order not to stop trace-cmd.service at system shutdown, it's
 necessary to remove the default Conflicts=shutdown.target
 dependency. This is achieved by DefaultDependencies=no.
 Also, we need to consider a default dependency around basic.target
 that is explained in man 7 systemd.special as follows:
     basic.target
         A special target unit covering basic boot-up.
         systemd automatically adds dependencies of the types
         Requires= and After= for this target unit to all
         services (except for those with DefaultDependencies=no).
         Usually this should pull-in all mount points, swap
         devices, sockets, timers, and path units and other basic
         initialization necessary for general purpose daemons.
 As this explains, Requires=basic.target is assigned to each service by
 default.
 Requires=basic.target means that the service tries to pull in the
 basic.target when it's pulled in and gets stopped if the basic.target
 gets stopped.
 This means that trace-cmd.service gets stopped at system shutdown via
 Requires=basic.target when basic.target is stopped.
 Thus, not to stop trace-cmd.service at system shutdown, it's necessary
 to remove the default Requires=basic.target dependency. This is again
 achieved by DefaultDependencies=no.
 3) Don't stop trace-cmd.service at each kernel module loading
 We have now udev configuration that restarts trace-cmd.service each
 time some kernel module is loaded. However, systemctl restart
 trace-cmd.service means that systemctl stop trace-cmd.service and then
 systemctl start trace-cmd.service. trace data gets lost when the
 systemctl stop trace-cmd.service is executed as I explained above.
 To fix the issue, we remove trace-cmd reset from ExecReload= in
 trace-cmd.service and use systemctl reload trace-cmd.service in the
 udev script instead of systemctl try-restart trace-cmd.service.
 Note that it's enough to trace-cmd start to enable trace events of
 newly loaded kernel modules.
 Also note that systemctl is-active trace-cmd.service in the udev
 script is needed to avoid executing systemctl reload trace-cmd.service
 when trace-cmd.service is inactive. Without systemctl is-active
 trace-cmd.service, systemctl reload trace-cmd.service is executed even
 when trace-cmd.service is inactive and then logs the following
 message:
  Jun 12 20:24:25 localhost systemd: Unit trace-cmd.service cannot be reloaded because it is inactive.
 4) Start trace-cmd.service before any normal services
 trace-cmd.service needs to start early enough to collect useful kernel
 event information. It's too late if any of the normal services has
 started.
 To achieve this, DefaultDependencies=no is again needed to remove
 After=basic.target dependency assigned by default that is explained in
 man 7 systemd.special.
 Also, we need Before=basic.target to start trace-cmd.service *before*
 any normal services, i.e. any services with the default
 After=basic.target dependency.

 Subject: [PATCH] tools lib traceevent: Fix missing equality check for strcmp
 There was a missing comparison with 0 when checking if type is "s64" or
 "u64". Therefore, the body of the if-statement was entered if "type" was
 "u64" or not "s64", which made the first strcmp() redundant since if
 type is "u64", it's not "s64".
 If type is "s64", the body of the if-statement is not entered but since
 the remainder of the function consists of if-statements which will not
 be entered if type is "s64", we will just return "val", which is
 correct, albeit at the cost of a few more calls to strcmp(), i.e., it
 will behave just as if the if-statement was entered.
 If type is neither "s64" or "u64", the body of the if-statement will be
 entered incorrectly and "val" returned. This means that any type that is
 checked after "s64" and "u64" is handled the same way as "s64" and
 "u64", i.e., the limiting of "val" to fit in for example "s8" is never
 reached.
 This was introduced in the kernel tree when the sources were copied from
 trace-cmd in commit f7d82350e597 ("tools/events: Add files to create
 libtraceevent.a"), and in the trace-cmd repo in 1cdbae6035cei
 ("Implement typecasting in parser") when the function was introduced,
 i.e., it has always behaved the wrong way.
 Detected by cppcheck.

 Subject: [PATCH] trace-cmd: Add option to poll trace buffers
 Waiting for data to be available on the trace ring-buffers may trigger
 IPIs. This might generate unacceptable trace noise when debugging low
 latency or real time systems. So introduce the poll option. When
 enabled, it forces trace-cmd to use O_NONBLOCK. The drawback to using it
 is that traces will be extracted by busy waiting, which will
 unnecessarily hog the CPUs, so only use when really needed.

 Date: Wed, 17 Apr 2019 16:09:58 +0300
 Subject: [PATCH 1/2] trace-cmd: Optimize how pid filters are expressed
 Express pid filters as allowed/disallowed filter ranges
  (pid>=100&&pid<=103)
 instead of specifying them per pid
  (pid==100||pid==101||pid==102||pid==103)
 This makes the size of the resulting filter smaller (and faster) and avoids
 overflowing the filter size limit of one page which we can hit on bigger
 machines (say >160 CPUs).

 About
 Trace-cmd tests according to the CI wiki specifically the standard test interface in the [spec](https://fedoraproject.org/wiki/Changes/InvokingTests).
 The playbook includes Tier1 level test cases that have been tested in classic contexts and is passing reliably.
 The following steps are used to execute the tests using the standard test interface:
 Test environment
 Make sure you have installed packages from the spec
    `# dnf install ansible python2-dnf libselinux-python standard-test-roles ansible python2-dnf libselinux-python standard-test-roles`
 Run tests for Classic
 ~~~~
    # export TEST_SUBJECTS=
    # sudo ansible-playbook --tags=classic tests.yml

 Subject: [PATCH] trace-cmd: Prevent buffer overflow in update_pid_filters()
 The buffer in which the updated filter is written in
 update_pid_filters() is missing one byte to store the null character.
 It fixes the following error:
 $ trace-cmd start -e irq:* -e sched:* -P 1
 *** buffer overflow detected ***: terminated
 Aborted (core dumped)
 Fixes: 5502bcef0f962 ("trace-cmd: Handle filtered PIDs per ftarce instance")

 Check that do_lseek doesn't fail before calling malloc() with a -1

 This is flagged as an overrun error (CWE-119) by static anaysis
 because of the call to read() later, but I don't imagine that malloc
 would succeed.

 Subject: [PATCH 8/8] trace-cmd record: Check the length of the protocol
 version received
 In check_protocol_version we compare the protocol version string with
 the expected one ("V3") with memcmp(). The received string could be
 longer than the constant string used for the comparison. That could
 lead to out of range access.
 Use the known length of the fixed "V3" string for the comparison and
 check that the received protocol version is not too short.

 From e48db64dcb0dfddb6b8f6cd8624e1e2ff2c1302c Mon Sep 17 00:00:00 2001
 From: Jerome Marchand <jmarchan@redhat.com>
 Date: Tue, 29 Oct 2024 09:01:14 +0100
 Subject: [PATCH 5/8] trace-cmd record: Prevent memory leak in setup_network()
 Because of the again label, msg_handle can be already allocated if we
 exit after we got a negative socket file descriptor. Free it there.
 Also unassign msg_handle->fd as to not double close sfd.
 Fixes a RESOURCE_LEAK error (CWE-772)
