+Subject: ASoC: qdsp6: q6routing: Fix return value from msm_routing_put_audio_mixer
+
+From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>
+
+commit 4739d88ad8e1900f809f8a5c98f3c1b65bf76220 upstream.
+
+msm_routing_put_audio_mixer() can return incorrect value in various scenarios.
+
+scenario 1:
+amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1
+amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 0
+
+return value is 0 instead of 1 eventhough value was changed
+
+scenario 2:
+amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1
+amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 1
+
+return value is 1 instead of 0 eventhough the value was not changed
+
+scenario 3:
+amixer cset iface=MIXER,name='SLIMBUS_0_RX Audio Mixer MultiMedia1' 0
+return value is 1 instead of 0 eventhough the value was not changed
+
+Fix this by adding checks, so that change notifications are sent correctly.

+
+commit 8aa55ab422d9d0d825ebfb877702ed661e96e682 upstream.
+
+After setting pre-set combined to 16 queues and reserving 16 queues by
+tc qdisc, pre-set maximum combined queues returned to default value
+after VF reset being 4 and this generated errors during removing tc.
+Fixed by removing clear num_req_queues before reset VF.

+Subject: net: cdc_ncm: Allow for dwNtbOutMaxSize to be unset or zero
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Lee Jones <lee.jones@linaro.org>
+
+commit 2be6d4d16a0849455a5c22490e3c5983495fed00 upstream.
+
+Currently, due to the sequential use of min_t() and clamp_t() macros,
+in cdc_ncm_check_tx_max(), if dwNtbOutMaxSize is not set, the logic
+sets tx_max to 0. This is then used to allocate the data area of the
+SKB requested later in cdc_ncm_fill_tx_frame().
+
+This does not cause an issue presently because when memory is
+allocated during initialisation phase of SKB creation, more memory
+(512b) is allocated than is required for the SKB headers alone (320b),
+leaving some space (512b - 320b = 192b) for CDC data (172b).
+
+However, if more elements (for example 3 x u64 = [24b]) were added to
+one of the SKB header structs, say 'struct skb_shared_info',
+increasing its original size (320b [320b aligned]) to something larger
+(344b [384b aligned]), then suddenly the CDC data (172b) no longer
+fits in the spare SKB data area (512b - 384b = 128b).
+
+Consequently the SKB bounds checking semantics fails and panics:
+
+ skbuff: skb_over_panic: text:ffffffff830a5b5f len:184 put:172 \
+ head:ffff888119227c00 data:ffff888119227c00 tail:0xb8 end:0x80 dev:<NULL>

+By overriding the max value with the default CDC_NCM_NTB_MAX_SIZE_TX

+Subject: net: fec: only clear interrupt of handling queue in fec_enet_rx_queue()
+
+From: Joakim Zhang <qiangqing.zhang@nxp.com>
+
+commit b5bd95d17102b6719e3531d627875b9690371383 upstream.
+
+Background:
+We have a customer is running a Profinet stack on the 8MM which receives and
+responds PNIO packets every 4ms and PNIO-CM packets every 40ms. However, from
+time to time the received PNIO-CM package is "stock" and is only handled when
+receiving a new PNIO-CM or DCERPC-Ping packet (tcpdump shows the PNIO-CM and
+the DCERPC-Ping packet at the same time but the PNIO-CM HW timestamp is from
+the expected 40 ms and not the 2s delay of the DCERPC-Ping).
+
+After debugging, we noticed PNIO, PNIO-CM and DCERPC-Ping packets would
+be handled by different RX queues.
+
+The root cause should be driver ack all queues' interrupt when handle a
+specific queue in fec_enet_rx_queue(). The blamed patch is introduced to
+receive as much packets as possible once to avoid interrupt flooding.
+But it's unreasonable to clear other queues'interrupt when handling one
+queue, this patch tries to fix it.
+
+Fixes: ed63f1dcd578 (net: fec: clear receive interrupts before processing a packet)

+Subject: net/qla3xxx: fix an error code in ql_adapter_up()
+
+From: Dan Carpenter <dan.carpenter@oracle.com>
+
+commit d17b9737c2bc09b4ac6caf469826e5a7ce3ffab7 upstream.
+
+The ql_wait_for_drvr_lock() fails and returns false, then this
+function should return an error code instead of returning success.
+
+The other problem is that the success path prints an error message
+netdev_err(ndev, "Releasing driver lock\n"); Delete that and
+re-order the code a little to make it more clear.

+Subject: qede: validate non LSO skb length
+
+From: Manish Chopra <manishc@marvell.com>
+
+commit 8e227b198a55859bf790dc7f4b1e30c0859c6756 upstream.
+
+Although it is unlikely that stack could transmit a non LSO
+skb with length > MTU, however in some cases or environment such
+occurrences actually resulted into firmware asserts due to packet
+length being greater than the max supported by the device (~9700B).
+
+This patch adds the safeguard for such odd cases to avoid firmware
+asserts.
+
+v2: Added "Fixes" tag with one of the initial driver commit
+ which enabled the TX traffic actually (as this was probably
+ day1 issue which was discovered recently by some customer
+ environment)

+Subject: tools build: Remove needless libpython-version feature check that breaks test-all fast path
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Arnaldo Carvalho de Melo <acme@redhat.com>
+
+commit 3d1d57debee2d342a47615707588b96658fabb85 upstream.
+
+Since 66dfdff03d196e51 ("perf tools: Add Python 3 support") we don't use
+the tools/build/feature/test-libpython-version.c version in any Makefile
+feature check:
+
+ $ find tools/ -type f | xargs grep feature-libpython-version
+ $
+
+The only place where this was used was removed in 66dfdff03d196e51:
+
+ - ifneq ($(feature-libpython-version), 1)
+ - $(warning Python 3 is not yet supported; please set)
+ - $(warning PYTHON and/or PYTHON_CONFIG appropriately.)
+ - $(warning If you also have Python 2 installed, then)
+ - $(warning try something like:)
+ - $(warning $(and ,))
+ - $(warning $(and ,) make PYTHON=python2)
+ - $(warning $(and ,))
+ - $(warning Otherwise, disable Python support entirely:)
+ - $(warning $(and ,))
+ - $(warning $(and ,) make NO_LIBPYTHON=1)
+ - $(warning $(and ,))
+ - $(error $(and ,))
+ - else
+ - LDFLAGS += $(PYTHON_EMBED_LDFLAGS)
+ - EXTLIBS += $(PYTHON_EMBED_LIBADD)
+ - LANG_BINDINGS += $(obj-perf)python/perf.so
+ - $(call detected,CONFIG_LIBPYTHON)
+ - endif
+
+And nowadays we either build with PYTHON=python3 or just install the
+python3 devel packages and perf will build against it.
+
+But the leftover feature-libpython-version check made the fast path
+feature detection to break in all cases except when python2 devel files
+were installed:
+
+ $ rpm -qa | grep python.*devel
+ python3-devel-3.9.7-1.fc34.x86_64
+ $ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf ;
+ $ make -C tools/perf O=/tmp/build/perf install-bin
+ make: Entering directory '/var/home/acme/git/perf/tools/perf'
+ BUILD: Doing 'make -j32' parallel build
+ HOSTCC /tmp/build/perf/fixdep.o
+ <SNIP>
+ $ cat /tmp/build/perf/feature/test-all.make.output
+ In file included from test-all.c:18:
+ test-libpython-version.c:5:10: error: #error
+ 5 | #error
+ | ^~~~~
+ $ ldd ~/bin/perf | grep python
+ libpython3.9.so.1.0 => /lib64/libpython3.9.so.1.0 (0x00007fda6dbcf000)
+ $
+
+As python3 is the norm these days, fix this by just removing the unused
+feature-libpython-version feature check, making the test-all fast path
+to work with the common case.
+
+With this:
+
+ $ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf ;
+ $ make -C tools/perf O=/tmp/build/perf install-bin |& head
+ make: Entering directory '/var/home/acme/git/perf/tools/perf'
+ BUILD: Doing 'make -j32' parallel build
+ HOSTCC /tmp/build/perf/fixdep.o
+ HOSTLD /tmp/build/perf/fixdep-in.o
+ LINK /tmp/build/perf/fixdep
+
+ Auto-detecting system features:
+ ... dwarf: [ on ]
+ ... dwarf_getlocations: [ on ]
+ ... glibc: [ on ]
+ $ ldd ~/bin/perf | grep python
+ libpython3.9.so.1.0 => /lib64/libpython3.9.so.1.0 (0x00007f58800b0000)
+ $ cat /tmp/build/perf/feature/test-all.make.output
+ $

+Subject: tracefs: Set all files to the same group ownership as the mount option
+
+From: Steven Rostedt (VMware) <rostedt@goodmis.org>
+
+commit 48b27b6b5191e2e1f2798cd80877b6e4ef47c351 upstream.
+
+As people have been asking to allow non-root processes to have access to
+the tracefs directory, it was considered best to only allow groups to have
+access to the directory, where it is easier to just set the tracefs file
+system to a specific group (as other would be too dangerous), and that way
+the admins could pick which processes would have access to tracefs.
+
+Unfortunately, this broke tooling on Android that expected the other bit
+to be set. For some special cases, for non-root tools to trace the system,
+tracefs would be mounted and change the permissions of the top level
+directory which gave access to all running tasks permission to the
+tracing directory. Even though this would be dangerous to do in a
+production environment, for testing environments this can be useful.
+
+Now with the new changes to not allow other (which is still the proper
+thing to do), it breaks the testing tooling. Now more code needs to be
+loaded on the system to change ownership of the tracing directory.
+
+The real solution is to have tracefs honor the gid=xxx option when
+mounting. That is,
+
+(tracing group tracing has value 1003)
+
+ mount -t tracefs -o gid=1003 tracefs /sys/kernel/tracing
+
+should have it that all files in the tracing directory should be of the
+given group.
+
+Copy the logic from d_walk() from dcache.c and simplify it for the mount
+case of tracefs if gid is set. All the files in tracefs will be walked and
+their group will be set to the value passed in.
