+
+[ Upstream commit 3b8179944cb0dd53e5223996966746cdc8a60657 ]
+
+Draining makes little sense in the situation of hardware overrun, as the
+hardware will have consumed all its available samples. Additionally,
+draining whilst the stream is paused would presumably get stuck as no
+data is being consumed on the DSP side.

+Subject: ALSA: compress: Fix regression on compressed capture streams
+
+[ Upstream commit 4475f8c4ab7b248991a60d9c02808dbb813d6be8 ]
+
+A previous fix to the stop handling on compressed capture streams causes
+some knock on issues. The previous fix updated snd_compr_drain_notify to
+set the state back to PREPARED for capture streams. This causes some
+issues however as the handling for snd_compr_poll differs between the
+two states and some user-space applications were relying on the poll
+failing after the stream had been stopped.
+
+To correct this regression whilst still fixing the original problem the
+patch was addressing, update the capture handling to skip the PREPARED
+state rather than skipping the SETUP state as it has done until now.

+
+[ Upstream commit 26c3f1542f5064310ad26794c09321780d00c57d ]
+
+Currently, whilst in SNDRV_PCM_STATE_OPEN it is possible to call
+snd_compr_stop, snd_compr_drain and snd_compr_partial_drain, which
+allow a transition to SNDRV_PCM_STATE_SETUP. The stream should
+only be able to move to the setup state once it has received a
+SNDRV_COMPRESS_SET_PARAMS ioctl. Fix this issue by not allowing
+those ioctls whilst in the open state.

+Subject: iscsi_ibft: make ISCSI_IBFT dependson ACPI instead of ISCSI_IBFT_FIND
+
+[ Upstream commit 94bccc34071094c165c79b515d21b63c78f7e968 ]
+
+iscsi_ibft can use ACPI to find the iBFT entry during bootup,
+currently, ISCSI_IBFT depends on ISCSI_IBFT_FIND which is
+a X86 legacy way to find the iBFT by searching through the
+low memory. This patch changes the dependency so that other
+arch like ARM64 can use ISCSI_IBFT as long as the arch supports
+ACPI.
+
+ibft_init() needs to use the global variable ibft_addr declared
+in iscsi_ibft_find.c. A #ifndef CONFIG_ISCSI_IBFT_FIND is needed
+to declare the variable if CONFIG_ISCSI_IBFT_FIND is not selected.
+Moving ibft_addr into the iscsi_ibft.c does not work because if
+ISCSI_IBFT is selected as a module, the arch/x86/kernel/setup.c won't
+be able to find the variable at compile time.

+
+[ Upstream commit d2b3fe42bc629c2d4002f652b3abdfb2e72991c7 ]
+
+ieee80211_set_wmm_default() normally sets up the initial CW min/max for
+each queue, except that it skips doing this if the driver doesn't
+support ->conf_tx. We still end up calling drv_conf_tx() in some cases
+(e.g., ieee80211_reconfig()), which also still won't do anything
+useful...except it complains here about the invalid CW parameters.
+
+Let's just skip the WARN if we weren't going to do anything useful with
+the parameters.

+ request_module
+
+[ Upstream commit 1b0890cd60829bd51455dc5ad689ed58c4408227 ]
+
+Thomas and Juliana report a deadlock when running:
+
+(rmmod nf_conntrack_netlink/xfrm_user)
+
+ conntrack -e NEW -E &
+ modprobe -v xfrm_user
+
+They provided following analysis:
+
+conntrack -e NEW -E
+ netlink_bind()
+ netlink_lock_table() -> increases "nl_table_users"
+ nfnetlink_bind()
+ # does not unlock the table as it's locked by netlink_bind()
+ __request_module()
+ call_usermodehelper_exec()
+
+This triggers "modprobe nf_conntrack_netlink" from kernel, netlink_bind()
+won't return until modprobe process is done.
+
+"modprobe xfrm_user":
+ xfrm_user_init()
+ register_pernet_subsys()
+ -> grab pernet_ops_rwsem
+ ..
+ netlink_table_grab()
+ calls schedule() as "nl_table_users" is non-zero
+
+so modprobe is blocked because netlink_bind() increased
+nl_table_users while also holding pernet_ops_rwsem.
+
+"modprobe nf_conntrack_netlink" runs and inits nf_conntrack_netlink:
+ ctnetlink_init()
+ register_pernet_subsys()
+ -> blocks on "pernet_ops_rwsem" thanks to xfrm_user module
+
+both modprobe processes wait on one another -- neither can make
+progress.
+
+Switch netlink_bind() to "nowait" modprobe -- this releases the netlink
+table lock, which then allows both modprobe instances to complete.

+
+When perf_add_probe_events() we call cleanup_perf_probe_events() for the

+'perf probe' goes on and calls cleanup_params() and that will again call

+Subject: perf tools: Fix proper buffer size for feature processing
+
+[ Upstream commit 79b2fe5e756163897175a8f57d66b26cd9befd59 ]
+
+After Song Liu's segfault fix for pipe mode, Arnaldo reported following
+error:
+
+ # perf record -o - | perf script
+ 0x514 [0x1ac]: failed to process type: 80
+
+It's caused by wrong buffer size setup in feature processing, which
+makes cpu topology feature fail, because it's using buffer size to
+recognize its header version.

+
+[ Upstream commit a6ec414a4dd529eeac5c3ea51c661daba3397108 ]
+
+If the device driver were to send out a full queue's worth of SBALs,
+current code would end up discovering the last of those SBALs as PRIMED
+and erroneously skip the SIGA-w. This immediately stalls the queue.
+
+Add a check to not attempt fast-requeue in this case. While at it also
+make sure that the state of the previous SBAL was successfully extracted
+before inspecting it.

+Subject: test_firmware: fix a memory leak bug
+
+[ Upstream commit d4fddac5a51c378c5d3e68658816c37132611e1f ]
+
+In test_firmware_init(), the buffer pointed to by the global pointer
+'test_fw_config' is allocated through kzalloc(). Then, the buffer is
+initialized in __test_firmware_config_init(). In the case that the
+initialization fails, the following execution in test_firmware_init() needs
+to be terminated with an error code returned to indicate this failure.
+However, the allocated buffer is not freed on this execution path, leading
+to a memory leak bug.
+
+To fix the above issue, free the allocated buffer before returning from
+test_firmware_init().

+Subject: tty/ldsem, locking/rwsem: Add missing ACQUIRE to read_failed sleep
+ loop
+
+[ Upstream commit 952041a8639a7a3a73a2b6573cb8aa8518bc39f8 ]
+
+While reviewing rwsem down_slowpath, Will noticed ldsem had a copy of
+a bug we just found for rwsem.
+
+ X = 0;
+
+ CPU0 CPU1
+
+ rwsem_down_read()
+ for (;;) {
+ set_current_state(TASK_UNINTERRUPTIBLE);
+
+ X = 1;
+ rwsem_up_write();
+ rwsem_mark_wake()
+ atomic_long_add(adjustment, &sem->count);
+ smp_store_release(&waiter->task, NULL);
+
+ if (!waiter.task)
+ break;
+
+ ...
+ }
+
+ r = X;
+
+Allows 'r == 0'.
