[ Upstream commit 67300abd ] Currently an out of range dev->nr is detected by just reporting the issue and later on an out-of-bounds read on array card occurs because of this. Fix this by checking the upper range of dev->nr with the size of array card (removes the hard coded size), move this check earlier and also exit with the error -ENOSYS to avoid the later out-of-bounds array read. Detected by CoverityScan, CID#711191 ("Out-of-bounds-read") Fixes: commit 02b20b0b ("V4L/DVB (12730): Add conexant cx25821 driver") Signed-off-by:

[ Upstream commit 65243386 ] The vivid driver has two custom controls that change the behavior of RDS. Depending on the control setting the V4L2_CAP_READWRITE capability is toggled. However, after an earlier commit the capability was no longer set correctly. This is now fixed. Fixes: 9765a32c ("vivid: set device_caps in video_device") Signed-off-by:

[ Upstream commit d13a0139 ] Fixes vb2_vmalloc_get_userptr() to ioremap correct area. Since the current code does ioremap the page address, if the offset > 0, it does not do ioremap the last page and results in kernel panic. This fixes to pass the size + offset to ioremap so that ioremap can map correct area. Also, this uses __pfn_to_phys() to get the physical address of given PFN. Signed-off-by:

[ Upstream commit a398e043 ] While experimenting with older compiler versions, I ran into a warning that no longer shows up on gcc-4.8 or newer: drivers/media/platform/s3c-camif/camif-capture.c: In function '__camif_subdev_try_format': drivers/media/platform/s3c-camif/camif-capture.c:1265:25: error: array subscript is below array bounds This is an off-by-one bug, leading to an access before the start of the array, while newer compilers silently assume this undefined behavior cannot happen and leave the loop at index 0 if no other entry matches. As Sylvester explains, we actually need to ensure that the value is within the range, so this reworks the loop to be easier to parse correctly, and an additional check to fall back on the first format value for any unexpected input. I found an existing gcc bug for it and added a reduced version of the function there.

[ Upstream commit a8321e78 ] Rates declared in PLL rate tables should match exactly rates calculated from PLL coefficients. If that is not the case, rate of the PLL's child clock might be set not as expected. For instance, if in the PLL rates table we have a 393216000 Hz entry and the real value as returned by the PLL's recalc_rate callback is 393216003, after setting PLL's clk rate to 393216000 clk_get_rate will return 393216003. If we now attempt to set rate of a PLL's child divider clock to 393216000/2 its rate will be 131072001, rather than 196608000. That is, the divider will be set to 3 instead of 2, because 393216003/2 is greater than 196608000. To fix this issue declared rates are changed to exactly match rates generated by the PLL, as calculated from the P, M, S, K coefficients. In this patch an erroneous P value for 74176002 output frequency is also corrected. Signed-off-by:

[ Upstream commit 4bf59902 ] The MMC sample and drv clock for rockchip platforms are derived from the bus clock output to the MMC/SDIO card. So it should never happens that the clk rate is zero given it should inherits the clock rate from its parent. If something goes wrong and makes the clock rate to be zero, the calculation would be wrong but may still make the mmc tuning process work luckily. However it makes people harder to debug when the following data transfer is unstable. Signed-off-by:

[ Upstream commit 1f9c63e8 ] It's found that the clock phase output from clk_summary is wrong compared to the actual phase reading from the register. cat /sys/kernel/debug/clk/clk_summary | grep sdio_sample sdio_sample 0 1 0 50000000 0 -22 It exposes an issue that clk core, clk_core_get_phase, always returns the cached core->phase which should be either updated by calling clk_set_phase or directly from the first place the clk was registered. When registering the clk, the core->phase geting from ->get_phase() may return negative value indicating error. This is quite common since the clk's phase may be highly related to its parent chain, but it was temporarily orphan when registered, since its parent chains hadn't be ready at that time, so the clk drivers decide to return error in this case. However, if no clk_set_phase is called or maybe the ->set_phase() isn't even implemented, the core->phase would never be updated. This is wrong, and we should try to update it when all its parent chains are settled down, like the way of updating clock rate for that. But it's not deserved to complicate the code now and just update it anyway when calling clk_core_get_phase, which would be much simple and enough. Signed-off-by:

[ Upstream commit 4b0556a4 ] commit c420c1e4db22 ("clk: rockchip: Prevent calculating mmc phase if clock rate is zero") catches one gremlin again for clk-rk3228.c that the parent of SDMMC phase clock should be sclk_sdmmc0, but not sclk_sdmmc. However, the naming of the sdmmc clocks varies in the manual with the card clock having the 0 while the hclk is named without appended 0. So standardize one one format to prevent confusion, as there also is only one (non-sdio) mmc controller on the soc. Signed-off-by:

[ Upstream commit 04673e38 ] The driver controls when the hardware sends completions that communicate consumption of elements from the WQ. This is done by setting a WQEC bit on a WQE. The current driver sets it on every Nth WQE posting. However, the driver isn't clearing the bit if the WQE is reused. Thus, if the queue depth isn't evenly divisible by N, with enough time, it can be set on every element, creating a lot of overhead and risking CQ full conditions. Correct by clearing the bit when not setting it on an Nth element. Signed-off-by:

[ Upstream commit 00c20cdc ] When aacraid init fails with "AAC0: adapter self-test failed.", shutdown leads to UBSAN warning and then oops: [154316.118423] ================================================================================ [154316.118508] UBSAN: Undefined behaviour in drivers/scsi/scsi_lib.c:2328:27 [154316.118566] member access within null pointer of type 'struct Scsi_Host' [154316.118631] CPU: 2 PID: 14530 Comm: reboot Tainted: G W 4.15.0-dirty #89 [154316.118701] Hardware name: Hewlett Packard HP NetServer/HP System Board, BIOS 4.06.46 PW 06/25/2003 [154316.118774] Call Trace: [154316.118848] dump_stack+0x48/0x65 [154316.118916] ubsan_epilogue+0xe/0x40 [154316.118976] __ubsan_handle_type_mismatch+0xfb/0x180 [154316.119043] scsi_block_requests+0x20/0x30 [154316.119135] aac_shutdown+0x18/0x40 [aacraid] [154316.119196] pci_device_shutdown+0x33/0x50 [154316.119269] device_shutdown+0x18a/0x390 [...] [154316.123435] BUG: unable to handle kernel NULL pointer dereference at 000000f4 [154316.123515] IP: scsi_block_requests+0xa/0x30 This is because aac_shutdown() does struct Scsi_Host *shost = pci_get_drvdata(dev); scsi_block_requests(shost); and that assumes shost has been assigned with pci_set_drvdata(). However, pci_set_drvdata(pdev, shost) is done in aac_probe_one() far after bailing out with error from calling the init function ((*aac_drivers[index].init)(aac)), and when the init function fails, no error is returned from aac_probe_one() so PCI layer assumes there is driver attached, and tries to shut it down later. Fix it by returning error from aac_probe_one() when card-specific init function fails. This fixes reboot on my HP NetRAID-4M with dead battery. Signed-off-by:

[ Upstream commit c02189e1 ] A left shift must shift less than the bit width of the left argument. Avoid triggering undefined behavior if ha->mbx_count == 32.

[ Upstream commit ecf7ff49 ] When a request times out we set the io_req flag BNX2FC_FLAG_IO_COMPL so that if a subsequent completion comes in on that task ID we will ignore it. The issue is that in the check for this flag there is a missing return so we will continue to process a request which may have already been returned to the ownership of the SCSI layer. This can cause unpredictable results. Solution is to add in the missing return. [mkp: typo plus title shortening] Signed-off-by:

[ Upstream commit 96d5eaa9 ] While testing with the ARM specific memset() macro removed, I ran into a compiler warning that shows an old bug: drivers/scsi/arm/fas216.c: In function 'fas216_rq_sns_done': drivers/scsi/arm/fas216.c:2014:40: error: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to provide an explicit length? [-Werror=sizeof-pointer-memaccess] It turns out that the definition of the scsi_cmd structure changed back in linux-2.6.25, so now we clear only four bytes (sizeof(pointer)) instead of 96 (SCSI_SENSE_BUFFERSIZE). I did not check whether we actually need to initialize the buffer here, but it's clear that if we do it, we should use the correct size.

[ Upstream commit 17556cdb ] Commit 8f18c8a4 ("staging: lustre: lmv: separate master object with master stripe") changed how lmo_root inodes were managed, particularly when LMV_HASH_FLAG_MIGRATION is not set. Previously lsm_md_oinfo[0].lmo_root was always a borrowed inode reference and didn't need to by iput(). Since the change, that special case only applies when LMV_HASH_FLAG_MIGRATION is set In the upstream (lustre-release) version of this patch [Commit 60e07b972114 ("LU-4690 lod: separate master object with master stripe")] the for loop in the lmv_unpack_md() was changed to count from 0 and to ignore entry 0 if LMV_HASH_FLAG_MIGRATION is set. In the patch that got applied to Linux, that change was missing, so lsm_md_oinfo[0].lmo_root is never iput(). This results in a "VFS: Busy inodes" warning at unmount.
