commit c64baa3a upstream. AML opcodes come in two lengths: 1-byte opcodes and 2-byte, extended opcodes. If an error occurs due to illegal opcodes during table load, the AML parser needs to continue loading the table. In order to do this, it needs to skip parsing of the offending opcode and operands associated with that opcode. This change fixes the AML parse loop to correctly skip parsing of incorrect extended opcodes. Previously, only the short opcodes were skipped correctly. Signed-off-by:

commit 4abb951b upstream. The table load process omitted adding the operation region address range to the global list. This omission is problematic because the OS queries the global list to check for address range conflicts before deciding which drivers to load. This commit may result in warning messages that look like the following: [ 7.871761] ACPI Warning: system_IO range 0x00000428-0x0000042F conflicts with op_region 0x00000400-0x0000047F (\PMIO) (20180531/utaddress-213) [ 7.871769] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver However, these messages do not signify regressions. It is a result of properly adding address ranges within the global address list. Link: https://bugzilla.kernel.org/show_bug.cgi?id=200011Tested-by:

commit 95691e3e upstream. Currently, "disable_clkrun" yenta_socket module parameter is only implemented for TI CardBus bridges. Add also an implementation for Ricoh bridges that have the necessary setting documented in publicly available datasheets. Tested on a RL5C476II with a Sunrich C-160 CardBus NIC that doesn't work correctly unless the CLKRUN protocol is disabled. Let's also make it clear in its description that the "disable_clkrun" module parameter only works on these two previously mentioned brands of CardBus bridges. Signed-off-by:

commit da5e79bc upstream. If the policy limits change between invocations of cs_dbs_update(), the requested frequency value stored in dbs_info may not be updated and the function may use a stale value of it next time. Moreover, if idle periods are takem into account by cs_dbs_update(), the requested frequency value stored in dbs_info may be below the min policy limit, which is incorrect. To fix these problems, always update the requested frequency value in dbs_info along with the local copy of it when the previous requested frequency is beyond the policy limits and avoid decreasing the requested frequency below the min policy limit when taking idle periods into account.

commit e7c6a556 upstream. Devices with compatible="pmbus" field have zero initial page count, and pmbus_clear_faults() being called before the page count auto- detection does not actually clear faults because it depends on the page count. Non-cleared faults in its turn may fail the subsequent page count auto-detection.

commit 940ec770 upstream. Fixing/optimizing bcm_qspi_bspi_read() performance introduced two changes: 1) It added a loop to read all requested data using multiple BSPI ops. 2) It bumped max size of a single BSPI block request from 256 to 512 B. The later change resulted in occasional BSPI timeouts causing a regression. For some unknown reason hardware doesn't always handle reads as expected when using 512 B chunks. In such cases it may happen that BSPI returns amount of requested bytes without the last 1-3 ones. It provides the remaining bytes later but doesn't raise an interrupt until another LR start. Switching back to 256 B reads fixes that problem and regression. Fixes: 345309fa ("spi: bcm-qspi: Fix bcm_qspi_bspi_read() performance") Signed-off-by:

commit 53c83b59 upstream. With the current implementation, the complete() in the IRQ handler is supposed to be called only if the register status has one or the other RDY bit set. Other events might trigger an interrupt as well if enabled, but should not end-up with a complete() call. For this purpose, the code was checking if the other bits were set, in this case complete() was not called. This is wrong as two events might happen in a very tight time-frame and if the NDSR status read reports two bits set (eg. RDY(0) and RDDREQ) at the same time, complete() was not called. This logic would lead to timeouts in marvell_nfc_wait_op() and has been observed on PXA boards (NFCv1) in the Hamming write path.

[ Upstream commit 833eacc7 ] The MXS driver was calling back into the GPIO API from its irqchip. This is not very elegant, as we are a driver, let's just shortcut back into the gpio_chip .get() function instead. This is a tricky case since the .get() callback is not in this file, instead assigned by bgpio_init(). Calling the function direcly in the gpio_chip is however the lesser evil.

[ Upstream commit c61c7def ] Commit ea7e0480 ("MIPS: VDSO: Always map near top of user memory") set VDSO_RANDOMIZE_SIZE to 256MB for 64bit kernel. But take a look at arch/mips/mm/mmap.c we can see that MIN_GAP is 128MB, which means the mmap_base may be at (user_address_top - 128MB). This make the stack be surrounded by mmaped areas, then stack expanding fails and causes a segmentation fault. Therefore, VDSO_RANDOMIZE_SIZE should be less than MIN_GAP and this patch reduce it to 64MB. Signed-off-by:

commit 0962590e upstream. ALU operations on pointers such as scalar_reg += map_value_ptr are handled in adjust_ptr_min_max_vals(). Problem is however that map_ptr and range in the register state share a union, so transferring state through dst_reg->range = ptr_reg->range is just buggy as any new map_ptr in the dst_reg is then truncated (or null) for subsequent checks. Fix this by adding a raw member and use it for copying state over to dst_reg. Fixes: f1174f77 ("bpf/verifier: rework value tracking") Signed-off-by:

commit 0fe5119e upstream. Recently a check was added which prevents marking of routers with zero source address, but for IPv6 that cannot happen as the relevant RFCs actually forbid such packets: RFC 2710 (MLDv1): "To be valid, the Query message MUST come from a link-local IPv6 Source Address, be at least 24 octets long, and have a correct MLD checksum." Same goes for RFC 3810. And also it can be seen as a requirement in ipv6_mc_check_mld_query() which is used by the bridge to validate the message before processing it. Thus any queries with :: source address won't be processed anyway. So just remove the check for zero IPv6 source address from the query processing function.

[ Upstream commit 649f0837 ] It was reported that WoL from S5 is broken (WoL from S3 works) and the analysis showed that during system shutdown the network interface was brought down already when the actual kernel shutdown started. Therefore netif_running() returned false and as a consequence the PHY was suspended. Obviously WoL wasn't working then. To fix this the original patch needs to be effectively reverted. A side effect is that when normally bringing down the interface and WoL is enabled the PHY will remain powered on (like it was before the original patch).

[ Upstream commit 7de414a9 ] Most callers of pskb_trim_rcsum() simply drop the skb when it fails, however, ip_check_defrag() still continues to pass the skb up to stack. This is suspicious. In ip_check_defrag(), after we learn the skb is an IP fragment, passing the skb to callers makes no sense, because callers expect fragments are defrag'ed on success. So, dropping the skb when we can't defrag it is reasonable. Note, prior to commit 88078d98, this is not a big problem as checksum will be fixed up anyway. After it, the checksum is not correct on failure. Found this during code review.

[ Upstream commit 4ed591c8 ] The intent of ip6_route_check_nh_onlink is to make sure the gateway given for an onlink route is not actually on a connected route for a different interface (e.g., 2001:db8:1::/64 is on dev eth1 and then an onlink route has a via 2001:db8:1::1 dev eth2). If the gateway lookup hits the default route then it most likely will be a different interface than the onlink route which is ok. Update ip6_route_check_nh_onlink to disregard the device mismatch if the gateway lookup hits the default route. Turns out the existing onlink tests are passing because there is no default route or it is an unreachable default, so update the onlink tests to have a default route other than unreachable.
