2019-11-25drm/amdgpu: fix multiple memory leaks in acp_hw_initNavid Emamdoost
commit 57be09c6e8747bf48704136d9e3f92bfb93f5725 upstream. In acp_hw_init there are some allocations that needs to be released in case of failure: 1- adev->acp.acp_genpd should be released if any allocation attemp for adev->acp.acp_cell, adev->acp.acp_res or i2s_pdata fails. 2- all of those allocations should be released if mfd_add_hotplug_devices or pm_genpd_add_device fail. 3- Release is needed in case of time out values expire.

2019-11-25loop: change queue block size to match when using DIOMartijn Coenen
commit 85560117d00f5d528e928918b8f61cadcefff98b upstream. The loop driver assumes that if the passed in fd is opened with O_DIRECT, the caller wants to use direct I/O on the loop device. However, if the underlying block device has a different block size than the loop block queue, direct I/O can't be enabled. Instead of requiring userspace to manually change the blocksize and re-enable direct I/O, just change the queue block sizes to match, as well as the io_min size.

commit 7ae6d93c8f052b7a77ba56ed0f654e22a2876739 upstream. The QCA8K family supports up to 7 ports. So use the existing QCA8K_NUM_PORTS define to allocate the switch structure and limit all operations with the switch ports. This was not an issue until commit 0394a63acfe2 ("net: dsa: enable and disable all ports") disabled all unused ports.

2019-11-25nvme: allow 64-bit results in passthru commandsMarta Rybczynska
commit 65e68edce0db433aa0c2b26d7dc14fbbbeb89fbb upstream. It is not possible to get 64-bit results from the passthru commands, what prevents from getting for the Capabilities (CAP) property value. As a result, it is not possible to implement IOL's NVMe Conformance test 4.3 Case 1 for Fabrics targets [1] (page 123). This issue has been already discussed [2], but without a solution. This patch solves the problem by adding new ioctls with a new passthru structure, including 64-bit results. The older ioctls stay unchanged.

commit f51913eef23f74c3bd07899dc7f1ed6df9e521d8 upstream. In some cases, hba may go through shutdown flow without successful initialization and then make system hang. For example, if ufshcd_change_power_mode() gets error and leads to ufshcd_hba_exit() to release resources of the host, future shutdown flow may hang the system since the host register will be accessed in unpowered state. To solve this issue, simply add checking to skip shutdown for above kind of situation.

2019-11-25RDMA/cxgb4: Do not dma memory off of the stackGreg KH
commit 3840c5b78803b2b6cc1ff820100a74a092c40cbb upstream. Nicolas pointed out that the cxgb4 driver is doing dma off of the stack, which is generally considered a very bad thing. On some architectures it could be a security problem, but odds are none of them actually run this driver, so it's just a "normal" bug. Resolve this by allocating the memory for a message off of the heap instead of the stack. kmalloc() always will give us a proper memory location that DMA will work correctly from.

commit 0f4f199443faca715523b0659aa536251d8b978f upstream. In iwl_pcie_ctxt_info_gen3_init there are cases that the allocated dma memory is leaked in case of error.

commit db4d30fbb71b47e4ecb11c4efa5d8aad4b03dfae upstream. Some processors may incur a machine check error possibly resulting in an unrecoverable CPU lockup when an instruction fetch encounters a TLB multi-hit in the instruction TLB. This can occur when the page size is changed along with either the physical address or cache type. The relevant erratum can be found here: https://bugzilla.kernel.org/show_bug.cgi?id=205195 There are other processors affected for which the erratum does not fully disclose the impact. This issue affects both bare-metal x86 page tables and EPT. It can be mitigated by either eliminating the use of large pages or by using careful TLB invalidations when changing the page size in the page tables. Just like Spectre, Meltdown, L1TF and MDS, a new bit has been allocated in MSR_IA32_ARCH_CAPABILITIES (PSCHANGE_MC_NO) and will be set on CPUs which are mitigated against this issue.

The legal result is saved to 'ioc'. Then, in condition MPT3COMMAND, the whole struct is fetched again from the userspace. Then _ctl_do_mpt_command() is called, 'ioc' and 'karg' as inputs. However, a malicious user can change the 'ioc_number' between the two fetches, which will cause a potential security issues. Moreover, a malicious user can provide a valid 'ioc_number' to pass the check in first fetch, and then modify it in the second fetch. To fix this, we need to recheck the 'ioc_number' in the second fetch.

commit 8c55dedb795be8ec0cf488f98c03a1c2176f7fb1 upstream. Nicolas Waisman noticed that even though noa_len is checked for a compatible length it's still possible to overrun the buffers of p2pinfo since there's no check on the upper bound of noa_num. Bound noa_num against P2P_MAX_NOA_NUM.

2019-11-09mtd: rawnand: au1550nd: Fix au_read_buf16() prototypePaul Burton
commit df8fed831cbcdce7b283b2d9c1aadadcf8940d05 upstream. Commit 7e534323c416 ("mtd: rawnand: Pass a nand_chip object to chip->read_xxx() hooks") modified the prototype of the struct nand_chip read_buf function pointer. In the au1550nd driver we have 2 implementations of read_buf. The previously mentioned commit modified the au_read_buf() implementation to match the function pointer, but not au_read_buf16(). This results in a compiler warning for MIPS db1xxx_defconfig builds: drivers/mtd/nand/raw/au1550nd.c:443:57: warning: pointer type mismatch in conditional expression Fix this by updating the prototype of au_read_buf16() to take a struct nand_chip pointer as its first argument, as is expected after commit 7e534323c416 ("mtd: rawnand: Pass a nand_chip object to chip->read_xxx() hooks"). Note that this shouldn't have caused any functional issues at runtime, since the offset of the struct mtd_info within struct nand_chip is 0 making mtd_to_nand() effectively a type-cast.

commit 30045f2174aab7fb4db7a9cf902d0aa6c75856a7 upstream. Since commit c2b71462d294 ("USB: core: Fix bug caused by duplicate interface PM usage counter") USB drivers must always balance their runtime PM gets and puts, including when the driver has already been unbound from the interface. Leaving the interface with a positive PM usage counter would prevent a later bound driver from suspending the device. Note that runtime PM has never actually been enabled for this driver since the support_autosuspend flag in its usb_driver struct is not set.

2019-11-09drm/i915: Mark contents as dirty on a write faultChris Wilson
commit b925708f28c2b7a3a362d709bd7f77bc75c1daac upstream. Since dropping the set-to-gtt-domain in commit a679f58d0510 ("drm/i915: Flush pages on acquisition"), we no longer mark the contents as dirty on a write fault. This has the issue of us then not marking the pages as dirty on releasing the buffer, which means the contents are not written out to the swap device (should we ever pick that buffer as a victim). Notably, this is visible in the dumb buffer interface used for cursors. Having updated the cursor contents via mmap, and swapped away, if the shrinker should evict the old cursor, upon next reuse, the cursor would be invisible.

commit 442f1e746e8187b9deb1590176f6b0ff19686b11 upstream. Commit 4b708b7b1a2c ("firmware: google: check if size is valid when decoding VPD data") adds length checks, but the new vpd_decode_entry() function botched the logic -- it adds the key length twice, instead of adding the key and value lengths separately. On my local system, this means vpd.c's vpd_section_create_attribs() hits an error case after the first attribute it parses, since it's no longer looking at the correct offset. With this patch, I'm back to seeing all the correct attributes in /sys/firmware/vpd/...

2019-11-09efivar/ssdt: Don't iterate over EFI vars if no SSDT override was specifiedArd Biesheuvel
commit c05f8f92b701576b615f30aac31fabdc0648649b upstream. The kernel command line option efivar_ssdt= allows the name to be specified of an EFI variable containing an ACPI SSDT table that should be loaded into memory by the OS, and treated as if it was provided by the firmware. Currently, that code will always iterate over the EFI variables and compare each name with the provided name, even if the command line option wasn't set to begin with. So bail early when no variable name was provided. This works around a boot regression on the 2012 Mac Pro, as reported by Scott.

commit dcb10920179ab74caf88a6f2afadecfc2743b910 upstream. End of conversion may be handled by using IRQ or DMA. There may be a race when two conversions complete at the same time on several ADCs. EOC can be read as 'set' for several ADCs, with: - an ADC configured to use IRQs. EOCIE bit is set. The handler is normally called in this case. - an ADC configured to use DMA. EOCIE bit isn't set. EOC triggers the DMA request instead. It's then automatically cleared by DMA read. But the handler gets called due to status bit is temporarily set (IRQ triggered by the other ADC). So both EOC status bit in CSR and EOCIE control bit must be checked before invoking the interrupt handler (e.g. call ISR only for IRQ-enabled ADCs).
