2020-08-03Merge branch 'bpf-libbpf-btf-parsing'Daniel Borkmann
Andrii Nakryiko says: ==================== It's pretty common for applications to want to parse raw (binary) BTF data from file, as opposed to parsing it from ELF sections. It's also pretty common for tools to not care whether given file is ELF or raw BTF format. This patch series exposes internal raw BTF parsing API and adds generic variant of BTF parsing, which will efficiently determine the format of a given fail and will parse BTF appropriately. Patches #2 and #3 removes re-implementations of such APIs from bpftool and resolve_btfids tools. ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

2020-08-03ALSA: usb-audio: Add support for Lenovo ThinkStation P620Kai-Heng Feng
Lenovo ThinkStation P620 is like other TRX40 boards, is equipped with two USB audio cards. USB device (17aa:104d) provides functionality for Internal Speaker and Front Headset. It's UAC v2, so it supports insertion control (jack detection). However, when trying to get the connector status of the speaker, an error occurs: [ 5.787405] usb 3-1: cannot get connectors status: req = 0x81, wValue = 0x200, wIndex = 0x1000, type = 0 Since the insertion control works perfectly for the headset, the error for speaker is probably casued by connecting internally. So let's relax the error for a bit if it's a speaker, and always reports it's connected. USB device (17aa:1046) is for rear Line-in, Line-out and Microphone. The insertion control works for all three jacks. However, there's an Function Unit that doesn't work: [ 5.905415] usb 3-6: cannot get ctl value: req = 0x83, wValue = 0xc00, wIndex = 0x1300, type = 4 [ 5.905418] usb 3-6: 19:0: cannot get min/max values for control 12 (id 19) So turn off the FU to avoid the error. Also, add specific card name for both devices, so userspace can easily indentify both cards.

2020-08-03PCI: Remove dev_err() when handing an error from platform_get_irq()Krzysztof Wilczyński
There is no need to call the dev_err() function directly to print a custom message when handling an error from either the platform_get_irq() or platform_get_irq_byname() functions as both are going to display an appropriate error message in case of a failure. This change is as per suggestions from Coccinelle, e.g., drivers/pci/controller/dwc/pcie-armada8k.c:252:2-9: line 252 is redundant because platform_get_irq() already prints an error [bhelgaas: squashed into one commit] Suggested-by: Bjorn Helgaas <bhelgaas@google.com> Link: https://lore.kernel.org/r/20200802142601.1635926-2-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-3-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-4-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-5-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-6-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-7-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-8-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-9-kw@linux.com Link: https://lore.kernel.org/r/20200802142601.1635926-10-kw@linux.com Link: https://lore.kernel.org/r/20200803071040.1663662-1-kw@linux.com Signed-off-by: Krzysztof Wilczyński <kw@linux.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Ley Foon Tan <ley.foon.tan@intel.com> # altera Acked-by: Jesper Nilsson <jesper.nilsson@axis.com> # dwc
2020-08-03tools, build: Propagate build failures from tools/build/Makefile.buildAndrii Nakryiko
The '&&' command seems to have a bad effect when $(cmd_$(1)) exits with non-zero effect: the command failure is masked (despite `set -e`) and all but the first command of $(dep-cmd) is executed (successfully, as they are mostly printfs), thus overall returning 0 in the end. This means in practice that despite compilation errors, tools's build Makefile will return success. We see this very reliably with libbpf's Makefile, which doesn't get compilation error propagated properly. This in turns causes issues with selftests build, as well as bpftool and other projects that rely on building libbpf. The fix is simple: don't use &&. Given `set -e`, we don't need to chain commands with &&. The shell will exit on first failure, giving desired behavior and propagating error properly.

2020-08-03erofs: fix extended inode could cross boundaryGao Xiang
Each ondisk inode should be aligned with inode slot boundary (32-byte alignment) because of nid calculation formula, so all compact inodes (32 byte) cannot across page boundary. However, extended inode is now 64-byte form, which can across page boundary in principle if the location is specified on purpose, although it's hard to be generated by mkfs due to the allocation policy and rarely used by Android use case now mainly for > 4GiB files. For now, only two fields `i_ctime_nsec` and `i_nlink' couldn't be read from disk properly and cause out-of-bound memory read with random value. Let's fix now.

There's also been a lot of work on the x86 code again, this time a big focus has been on cleaning up some issues identified by various static tests, and on the Freescale systems. Otherwise the biggest thing has been a lot of driver additions: - Convert users of digital_mute() to mute_stream(). - Simplify I/O helper functions. - Add a helper for getting the RTD from a substream. - Many, many fixes and cleanups to the x86 code. - New drivers for Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim MAX98360A and MAX98373 Soundwire, several Mediatek boards, nVidia Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards (some of the first phones I worked on!) and TI J721e EVM.

2020-08-03mac80211: Do not report beacon loss if beacon filtering enabledLoic Poulain
mac80211.h says: Beacon filter support is advertised with the IEEE80211_VIF_BEACON_FILTER interface capability. The driver needs to enable beacon filter support whenever power save is enabled, that is IEEE80211_CONF_PS is set. When power save is enabled, the stack will not check for beacon loss and the driver needs to notify about loss of beacons with ieee80211_beacon_loss(). Some controllers may want to dynamically enable the beacon filter capabilities on power save entry (CONF_PS) and disable it on exit. This is the case for the wcn36xx driver which only supports beacon filtering in PS mode (no CONNECTION_MONITOR support). When the mac80211 beacon monitor timer expires, the beacon filter flag must be checked again in case it as been changed in between (e.g. vif moved to PS mode).

At that time other calls like from nf_conntrack_in() can call of nf_ct_is_expired() and see the conn as expired.

2020-08-03mac80211: Handle special status codes in SAE commitJouni Malinen
SAE authentication has been extended with H2E (IEEE 802.11 REVmd) and PK (WFA) options. Those extensions use special status code values in the SAE commit messages (Authentication frame with transaction sequence number 1) to identify which extension is in use. mac80211 was interpreting those new values as the AP denying authentication and that resulted in failure to complete SAE authentication in some cases. Fix this by adding exceptions for the new status code values 126 and 127.

This reverts commit 9a6418487b56 ("ALSA: hda: call runtime_allow() for all hda controllers"). The reverted patch already introduced some regressions on some machines: - on gemini-lake machines, the error of "azx_get_response timeout" happens in the hda driver. - on the machines with alc662 codec, the audio jack detection doesn't work anymore.

2020-08-02md/raid5: Allow degraded raid6 to do rmwChangSyun Peng
Degraded raid6 always do reconstruct-write now. With raid6 xor supported, we can do rmw in degraded raid6. This patch can reduce many read IOs to improve performance. If the failed disk is P, Q or the disk we want to write to, we may need to do reconstruct-write in max degraded raid6. In this situation we can not read enough data from handle_stripe_dirtying() so we have to set force_rcw in handle_stripe_fill() to read all data.

2020-08-02md/raid5: Fix Force reconstruct-write io stuck in degraded raid5ChangSyun Peng
In degraded raid5, we need to read parity to do reconstruct-write when data disks fail. However, we can not read parity from handle_stripe_dirtying() in force reconstruct-write mode. Reproducible Steps: 1. Create degraded raid5 mdadm -C /dev/md2 --assume-clean -l5 -n3 /dev/sda2 /dev/sdb2 missing 2. Set rmw_level to 0 echo 0 > /sys/block/md2/md/rmw_level 3. IO to raid5 Now some io may be stuck in raid5. We can use handle_stripe_fill() to read the parity in this situation.

2020-08-03Revert "xen/balloon: Fix crash when ballooning on x86 32 bit PAE"Roger Pau Monne
This reverts commit dfd74a1edfaba5864276a2859190a8d242d18952. This has been fixed by commit dca4436d1cf9e0d237c which added the out of bounds check to __add_memory, so that trying to add blocks past MAX_PHYSMEM_BITS will fail. Note the check in the Xen balloon driver was bogus anyway, as it checked the start address of the resource, but it should instead test the end address to assert the whole resource falls below MAX_PHYSMEM_BITS.
