+Subject: perf/core: Fix the same task check in perf_event_set_output
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Kan Liang <kan.liang@linux.intel.com>
+
+[ Upstream commit 24d3ae2f37d8bc3c14b31d353c5d27baf582b6a6 ]
+
+The same task check in perf_event_set_output has some potential issues
+for some usages.
+
+For the current perf code, there is a problem if using of
+perf_event_open() to have multiple samples getting into the same mmap’d
+memory when they are both attached to the same process.
+https://lore.kernel.org/all/92645262-D319-4068-9C44-2409EF44888E@gmail.com/
+Because the event->ctx is not ready when the perf_event_set_output() is
+invoked in the perf_event_open().
+
+Besides the above issue, before the commit bd2756811766 ("perf: Rewrite
+core context handling"), perf record can errors out when sampling with
+a hardware event and a software event as below.
+ $ perf record -e cycles,dummy --per-thread ls
+ failed to mmap with 22 (Invalid argument)
+That's because that prior to the commit a hardware event and a software
+event are from different task context.
+
+The problem should be a long time issue since commit c3f00c70276d
+("perk: Separate find_get_context() from event initialization").
+
+The task struct is stored in the event->hw.target for each per-thread
+event. It is a more reliable way to determine whether two events are
+attached to the same task.
+
+The event->hw.target was also introduced several years ago by the
+commit 50f16a8bf9d7 ("perf: Remove type specific target pointers"). It
+can not only be used to fix the issue with the current code, but also
+back port to fix the issues with an older kernel.
+
+Note: The event->hw.target was introduced later than commit
+c3f00c70276d. The patch may cannot be applied between the commit
+c3f00c70276d and commit 50f16a8bf9d7. Anybody that wants to back-port
+this at that period may have to find other solutions.
+

+Subject: scsi: iscsi_tcp: Check that sock is valid before iscsi_set_param()
+
+From: Zhong Jinghua <zhongjinghua@huawei.com>
+
+[ Upstream commit 48b19b79cfa37b1e50da3b5a8af529f994c08901 ]
+
+The validity of sock should be checked before assignment to avoid incorrect
+values. Commit 57569c37f0ad ("scsi: iscsi: iscsi_tcp: Fix null-ptr-deref
+while calling getpeername()") introduced this change which may lead to
+inconsistent values of tcp_sw_conn->sendpage and conn->datadgst_en.
+
+Fix the issue by moving the position of the assignment.
