Using an empty (malformed) nodelist that is not caught during mount option parsing leads to a stack-out-of-bounds access. The option string that was used was: "mpol=prefer:,". However, MPOL_PREFERRED requires a single node number, which is not being provided here. Add a check that 'nodes' is not empty after parsing for MPOL_PREFERRED's nodeid.

Fixes the lower and upper bounds when there are multiple TCs and traffic is on the the same TC on the same device. The lower bound is represented by 'qoffset' and the upper limit for hash value is 'qcount + qoffset'. This gives a clean Rx to Tx queue mapping when there are multiple TCs, as the queue indices for upper TCs will be offset by 'qoffset'. v2: Fixed commit description based on comments.

Martin noticed that nct6775 driver does not load properly on his system in v5.4+ kernels. The issue was bisected to commit b84398d6d7f9 ("i2c: i801: Use iTCO version 6 in Cannon Lake PCH and beyond") but it is likely not the culprit because the faulty code has been in the driver already since commit 9424693035a5 ("i2c: i801: Create iTCO device on newer Intel PCHs"). So more likely some commit that added PCI IDs of recent chipsets made the driver to create the iTCO_wdt device on Martins system. The issue was debugged to be PCI configuration access to the PMC device that is not present. This returns all 1's when read and this caused the iTCO_wdt driver to accidentally request resourses used by nct6775. It turns out that the SMI resource is only required for some ancient systems, not the ones supported by this driver. For this reason do not populate the SMI resource at all and drop all the related code. The driver now always populates the main I/O resource and only in case of SPT (Intel Sunrisepoint) compatible devices it adds another resource for the NO_REBOOT bit. These two resources are of different types so platform_get_resource() used by the iTCO_wdt driver continues to find the both resources at index 0.

In a rare corner case the new logic for undo of SYNACK RTO could result in triggering the warning in tcp_fastretrans_alert() that says: WARN_ON(tp->retrans_out != 0); The warning looked like: WARNING: CPU: 1 PID: 1 at net/ipv4/tcp_input.c:2818 tcp_ack+0x13e0/0x3270 The sequence that tickles this bug is: - Fast Open server receives TFO SYN with data, sends SYNACK - (client receives SYNACK and sends ACK, but ACK is lost) - server app sends some data packets - (N of the first data packets are lost) - server receives client ACK that has a TS ECR matching first SYNACK, and also SACKs suggesting the first N data packets were lost - server performs TS undo of SYNACK RTO, then immediately enters recovery - buggy behavior then performed a *second* undo that caused the connection to be in CA_Open with retrans_out != 0 Basically, the incoming ACK packet with SACK blocks causes us to first undo the cwnd reduction from the SYNACK RTO, but then immediately enters fast recovery, which then makes us eligible for undo again. And then tcp_rcv_synrecv_state_fastopen() accidentally performs an undo using a "mash-up" of state from two different loss recovery phases: it uses the timestamp info from the ACK of the original SYNACK, and the undo_marker from the fast recovery. This fix refines the logic to only invoke the tcp_try_undo_loss() inside tcp_rcv_synrecv_state_fastopen() if the connection is still in CA_Loss. If peer SACKs triggered fast recovery, then tcp_rcv_synrecv_state_fastopen() can't safely undo.

In that case, the pq is left on the list. The code continues sending packets and potentially can complete the current request with the pq still on the dmawait list provided no descriptor shortage is seen. If the pq is torn down in that state, the sdma interrupt handler could find the now freed pq on the list with list corruption or memory corruption resulting. Fix by adding a flush routine to ensure that the pq is never on a list after processing a request. A follow-up patch series will address issues with seqlock surfaced in: https://lore.kernel.org/r/20200320003129.GP20941@ziepe.ca The seqlock use for sdma will then be converted to a spin lock since the list_empty() doesn't need the protection afforded by the sequence lock currently in use.

This reverts commit effd58c95f277744f75d6e08819ac859dbcbd351. blk_queue_split() is causing excessive IO splitting -- because blk_max_size_offset() depends on 'chunk_sectors' limit being set and if it isn't (as is the case for DM targets!) it falls back to splitting on a 'max_sectors' boundary regardless of offset. "Fix" this by reverting back to _not_ using blk_queue_split() in dm_process_bio() for normal IO (reads and writes). Long-term fix is still TBD but it should focus on training blk_max_size_offset() to call into a DM provided hook (to call DM's max_io_len()).

Some HP Pavilion x2 10 models use an AXP288 for charging and fuel-gauge. We use a native power_supply / PMIC driver in this case, because on most models with an AXP288 the ACPI AC / Battery code is either completely missing or relies on custom / proprietary ACPI OpRegions which Linux does not implement. The native drivers mostly work fine, but there are 2 problems: 1. These model uses a Type-C connector for charging which the AXP288 does not support. As long as a Type-A charger (which uses the USB data pins for charger type detection) is used everything is fine. But if a Type-C charger is used (such as the charger shipped with the device) then the charger is not recognized. So we end up slowly discharging the device even though a charger is connected, because we are limiting the current from the charger to 500mA. To make things worse this happens with the device's official charger. Looking at the ACPI tables HP has "solved" the problem of the AXP288 not being able to recognize Type-C chargers by simply always programming the input-current-limit at 3000mA and relying on a Vhold setting of 4.7V (normally 4.4V) to limit the current intake if the charger cannot handle this. 2. If no charger is connected when the machine boots then it boots with the vbus-path disabled. On other devices this is done when a 5V boost converter is active to avoid the PMIC trying to charge from the 5V boost output. This is done when an OTG host cable is inserted and the ID pin on the micro-B receptacle is pulled low, the ID pin has an ACPI event handler associated with it which re-enables the vbus-path when the ID pin is pulled high when the OTG cable is removed. The Type-C connector has no ID pin, there is no ID pin handler and there appears to be no 5V boost converter, so we end up not charging because the vbus-path is disabled, until we unplug the charger which automatically clears the vbus-path disable bit and then on the second plug-in of the adapter we start charging. The HP Pavilion x2 10 models with an AXP288 do have mostly working ACPI AC / Battery code which does not rely on custom / proprietary ACPI OpRegions. So one possible solution would be to blacklist the AXP288 native power_supply drivers and add the HP Pavilion x2 10 with AXP288 DMI ids to the list of devices which should use the ACPI AC / Battery code even though they have an AXP288 PMIC. This would require changes to 4 files: drivers/acpi/ac.c, drivers/power/supply/axp288_charger.c, drivers/acpi/battery.c and drivers/power/supply/axp288_fuel_gauge.c. Beside needing adding the same DMI matches to 4 different files, this approach also triggers problem 2. from above, but then when suspended, during suspend the machine will not wakeup because the vbus path is disabled by the AML code when not charging, so the Vbus low-to-high IRQ is not triggered, the CPU never wakes up and the device does not charge even though the user likely things it is charging, esp. since the charge status LED is directly coupled to an adapter being plugged in and does not reflect actual charging. This could be worked by enabling vbus-path explicitly from say the axp288_charger driver's suspend handler. So neither situation is ideal, in both cased we need to explicitly enable the vbus-path to work around different variants of problem 2 above, this requires a quirk in the axp288_charger code. If we go the route of using the ACPI AC / Battery drivers then we need modifications to 3 other drivers; and we need to partially disable the axp288_charger code, while at the same time keeping it around to enable vbus-path on suspend. OTOH we can copy the hardcoding of 3A input-current-limit (we never touch Vhold, so that would stay at 4.7V) to the axp288_charger code, which needs changes regardless, then we concentrate all special handling of this interesting device model in the axp288_charger code. That is what this commit does.

Commit f26661e12765 ("initramfs: make initramfs compression choice non-optional") has changed default compression mode. Previously we compress initramfs using available compression algorithm. Now we don't use any compression at all by default. It significantly increases the image size in case of build system chooses embedded initramfs. Initially I faced with this issue while using buildroot. As of today it's not possible to set preferred compression mode in target defconfig as this option depends on INITRAMFS_SOURCE being set. Modification of all build systems either doesn't look like good option. Let's instead rewrite initramfs compression mode choices list the way that "INITRAMFS_COMPRESSION_NONE" will be the last option in the list. In that case it will be chosen only if all other options (which implements any compression) are not available.

Because of this the framebuffer region might still be reserved even after drm_fb_helper_remove_conflicting_pci_framebuffers() returned. Don't consider pci_request_region() failure for the framebuffer region as fatal error to workaround this issue.

This restricts the panel to 8 bpc, not providing the full color depth of the panel on Linux <= 5.5. Additionally, commit '4a8ca46bae8a ("drm/amd/display: Default max bpc to 16 for eDP")' introduced into Linux 5.6-rc1 will unclamp panel depth to its full 10 bpc, thereby requiring a eDP bandwidth for all modes that exceeds the bandwidth available and causes all modes to fail validation -> No modes for the laptop panel -> failure to set any mode -> Panel goes dark. This patch adds a quirk specific to the MBP 2017 15" Retina panel to override reported max link rate to the correct maximum of 0xc = LINK_RATE_RBR2 to fix the darkness and reduced display precision. Please apply for Linux 5.6+ to avoid regressing Apple MBP panel support.

This is typical for Clang, which supports multiple LLVM backends. Even for GCC, we need to take care of biarch compiler cases. It is not a problem when we evaluate cc-option in Makefiles because cc-option is tested against the flag in question + $(KBUILD_CFLAGS). The cc-option in Kconfig, on the other hand, does not accumulate tested flags. Due to this simplification, it could potentially test cc-option against a different target. At first, Kconfig always evaluated cc-option against the host architecture. Since commit e8de12fb7cde ("kbuild: Check for unknown options with cc-option usage in Kconfig and clang"), in case of cross-compiling with Clang, the target triple is correctly passed to Kconfig. The case with biarch GCC (and native build with Clang) is still not handled properly. We need to pass some flags to specify the target machine bit. Due to the design, all the macros in Kconfig are expanded in the parse stage, where we do not know the target bit size yet. For example, arch/x86/Kconfig allows a user to toggle CONFIG_64BIT. If a compiler flag -foo depends on the machine bit, it must be tested twice, one with -m32 and the other with -m64. However, -m32/-m64 are not always recognized. So, this commits adds m64-flag and m32-flag macros. They expand to -m32, -m64, respectively if supported. Or, they expand to an empty string if unsupported. The typical usage is like this: config FOO bool default $(cc-option,$(m64-flag) -foo) if 64BIT default $(cc-option,$(m32-flag) -foo) This is clumsy, but there is no elegant way to handle this in the current static macro expansion. There was discussion for static functions vs dynamic functions. The consensus was to go as far as possible with the static functions.
