commit 904371f9 upstream. On i.MX6, the nearest upstream entity to the CSI can only be the CSI video muxes or the Synopsys DW MIPI CSI-2 receiver. However the i.MX53 has no CSI video muxes or a MIPI CSI-2 receiver. So allow for the nearest upstream entity to the CSI to be something other than those.

commit 63604a14 upstream. I previously added an RC_CORE dependency here, but missed the corner case of CONFIG_VIDEO_SECO_CEC=y with CONFIG_RC_CORE=m, which still causes a link error: drivers/media/platform/seco-cec/seco-cec.o: In function `secocec_probe': seco-cec.c:(.text+0x1b8): undefined reference to `devm_rc_allocate_device' seco-cec.c:(.text+0x2e8): undefined reference to `devm_rc_register_device' drivers/media/platform/seco-cec/seco-cec.o: In function `secocec_irq_handler': seco-cec.c:(.text+0xa2c): undefined reference to `rc_keydown' Refine the dependency to disallow building the RC subdriver in this case. This is the same logic we apply in other drivers like it. Fixes: f27dd0ad ("media: seco-cec: fix RC_CORE dependency") Cc: <stable@vger.kernel.org> # 5.1 Signed-off-by:

commit 933c1320 upstream. After removal of clock_start() from before soc_camera_init_i2c() in soc_camera_probe() by commit 9aea470b ("[media] soc-camera: switch I2C subdevice drivers to use v4l2-clk") introduced in v3.11, the ov6650 driver could no longer probe the sensor successfully because its clock was no longer turned on in advance. The issue was initially worked around by adding that missing clock_start() equivalent to OMAP1 camera interface driver - the only user of this sensor - but a propoer fix should be rather implemented in the sensor driver code itself. Fix the issue by inserting a delay between the clock is turned on and the sensor I2C registers are read for the first time. Tested on Amstrad Delta with now out of tree but still locally maintained omap1_camera host driver. Fixes: 9aea470b ("[media] soc-camera: switch I2C subdevice drivers to use v4l2-clk") Signed-off-by:

commit d69cb728 upstream. For SMB1 oplock breaks we would grab one credit while sending the PDU but we would never relese the credit back since we will never receive a response to this from the server. Eventuallt this would lead to a hang once all credits are leaked. Fix this by defining a new flag CIFS_NO_SRV_RSP which indicates that there is no server response to this command and thus we need to add any credits back immediately after sending the PDU.

commit b1a0ba8f upstream. The ACEPC T8 and T11 mini PCs contain quite generic names in the sys_vendor and product_name DMI strings, without this patch brcmfmac will try to load: "brcmfmac43455-sdio.Default string-Default string.txt" as nvram file which is way too generic. The DMI strings on which we are matching are somewhat generic too, but "To be filled by O.E.M." is less common then "Default string" and the system-sku and bios-version strings are pretty unique. Beside the DMI strings we also check the wifi-module chip-id and revision. I'm confident that the combination of all this is unique. Both the T8 and T11 use the same wifi-module, this commit adds DMI quirks for both mini PCs pointing to brcmfmac43455-sdio.acepc-t8.txt .

commit 5467a68c upstream. For lockless accesses to dentries we don't have pinned we rely (among other things) upon having an RCU delay between dropping the last reference and actually freeing the memory. On the other hand, for things like pipes and sockets we neither do that kind of lockless access, nor want to deal with the overhead of an RCU delay every time a socket gets closed. So delay was made optional - setting DCACHE_RCUACCESS in ->d_flags made sure it would happen. We tried to avoid setting it unless we knew we need it. Unfortunately, that had led to recurring class of bugs, in which we missed the need to set it. We only really need it for dentries that are created by d_alloc_pseudo(), so let's not bother with trying to be smart - just make having an RCU delay the default. The ones that do *not* get it set the replacement flag (DCACHE_NORCU) and we'd better use that sparingly. d_alloc_pseudo() is the only such user right now. FWIW, the race that finally prompted that switch had been between __lock_parent() of immediate subdirectory of what's currently the root of a disconnected tree (e.g. from open-by-handle in progress) racing with d_splice_alias() elsewhere picking another alias for the same inode, either on outright corrupted fs image, or (in case of open-by-handle on NFS) that subdirectory having been just moved on server. It's not easy to hit, so the sky is not falling, but that's not the first race on similar missed cases and the logics for settinf DCACHE_RCUACCESS has gotten ridiculously convoluted.

commit 2bc13b83 upstream. Currently if many flush requests are submitted to an md device is quick succession, they are serialized and can take a long to process them all. We don't really need to call flush all those times - a single flush call can satisfy all requests submitted before it started. So keep track of when the current flush started and when it finished, allow any pending flush that was requested before the flush started to complete without waiting any more.

commit 4bc034d3 upstream. This reverts commit 5a409b4f. This patch has two problems. 1/ it make multiple calls to submit_bio() from inside a make_request_fn. The bios thus submitted will be queued on current->bio_list and not submitted immediately. As the bios are allocated from a mempool, this can theoretically result in a deadlock - all the pool of requests could be in various ->bio_list queues and a subsequent mempool_alloc could block waiting for one of them to be released. 2/ It aims to handle a case when there are many concurrent flush requests. It handles this by submitting many requests in parallel - all of which are identical and so most of which do nothing useful. It would be more efficient to just send one lower-level request, but allow that to satisfy multiple upper-level requests.

commit 51e0f227 upstream. Commit 7bd1d409 ("stm class: Introduce an abstraction for System Trace Module devices") naively calculates the channel bitmap size in 64-bit chunks regardless of the size of underlying unsigned long, making the bitmap half as big on a 32-bit system. This leads to an out of bounds access with the upper half of the bitmap. Fix this by using BITS_TO_LONGS. While at it, convert to using struct_size() for the total size calculation of the master struct. Signed-off-by:

commit 70b46491 upstream. During several error paths in the function regulator_set_voltage_unlocked() the value of 'ret' can take on negative error values. However, in calls that go through the 'goto out' statement, this return value is lost and return 0 is used instead, indicating a 'pass'. There are several cases where this function should legitimately return a fail instead of a pass: one such case includes constraints check during voltage selection in the call to regulator_check_voltage(), which can have -EINVAL for the case when an unsupported voltage is incorrectly requested. In that case, -22 is expected as the return value, not 0. Fixes: 9243a195 ("regulator: core: Change voltage setting path") Cc: stable <stable@vger.kernel.org> Signed-off-by:

commit c7e2d94b upstream. Once blk_cleanup_queue() returns, tags shouldn't be used any more, because blk_mq_free_tag_set() may be called. Commit 45a9c9d9 ("blk-mq: Fix a use-after-free") fixes this issue exactly. However, that commit introduces another issue. Before 45a9c9d9, we are allowed to run queue during cleaning up queue if the queue's kobj refcount is held. After that commit, queue can't be run during queue cleaning up, otherwise oops can be triggered easily because some fields of hctx are freed by blk_mq_free_queue() in blk_cleanup_queue(). We have invented ways for addressing this kind of issue before, such as: 8dc765d4 ("SCSI: fix queue cleanup race before queue initialization is done") c2856ae2 ("blk-mq: quiesce queue before freeing queue") But still can't cover all cases, recently James reports another such kind of issue: https://marc.info/?l=linux-scsi&m=155389088124782&w=2 This issue can be quite hard to address by previous way, given scsi_run_queue() may run requeues for other LUNs. Fixes the above issue by freeing hctx's resources in its release handler, and this way is safe becasue tags isn't needed for freeing such hctx resource. This approach follows typical design pattern wrt. kobject's release handler.

Example: If start ping from VF0 (PF1) to VF1 (PF1) and mirror all traffic to VF0 (PF2), icmp reply to VF0 (PF1) and mirrored flow to VF0 (PF2) would be determined as same destination.

[ Upstream commit 12d5cbf8 ] When flow_rule_match_XYZ() functions were first introduced, flow_rule_match_cvlan() for inner vlan is missing. In mlx5_core driver, to get inner vlan key and mask, flow_rule_match_vlan() is just called, which is wrong because it obtains outer vlan information by FLOW_DISSECTOR_KEY_VLAN. This commit fixes this by changing to call flow_rule_match_cvlan() after it's added. Fixes: 8f256622 ("flow_offload: add flow_rule and flow_match structures and use them") Signed-off-by:

[ Upstream commit f1436c80 ] Prevent reading unsupported slave address from SFP EEPROM by testing Diagnostic Monitoring Type byte in EEPROM. Read only page zero of EEPROM, in case this byte is zero. If some SFP transceiver does not support Digital Optical Monitoring (DOM), reading SFP EEPROM slave address 0x51 could return an error. Availability of DOM support is verified by reading from zero page Diagnostic Monitoring Type byte describing how diagnostic monitoring is implemented by transceiver. If bit 6 of this byte is set, it indicates that digital diagnostic monitoring has been implemented. Otherwise it is not and transceiver could fail to reply to transaction for slave address 0x51 [1010001X (A2h)], which is used to access measurements page. Such issue has been observed when reading cable MCP2M00-xxxx, MCP7F00-xxxx, and few others.

[ Upstream commit c52ecff7 ] Old Mellanox silicons, like switchx-2, switch-ib do not support reading QSFP modules temperature through MTMP register. Attempt to access this register on systems equipped with the this kind of silicon will cause initialization flow failure. Test for hardware resource capability is added in order to distinct between old and new silicon - old silicons do not have such capability.
