2022-09-27docs: admin-guide: for kernel bugs refer to other kernel documentationLukas Bulwahn
The current section 'If something goes wrong' makes a number of suggestions for debugging, bug hunting and reporting issues, which are quite briefly described in that section. However, the suggestions are also well covered in other kernel documentation or sometimes simply outdated. Here, each suggestion in that section is summarized, and then followed with its assessment, and the derived action for each suggestion: - use MAINTAINERS and mailing list: covered in 'Reporting issues', summarized in the short guide, detailed in its further section. Reporting issues even provides some specific examples that guides readers well through the needed steps. Refer to 'Reporting issues'. - contact Linus Torvalds: probably outdated as currently described. nevertheless covered in 'Reporting issues'. Reporting issues points out to contact the relevant kernel maintainers first, and after some patience and failed attempts with those maintainers, contacting Linus Torvalds might be okay. Refer to 'Reporting issues'. - tell what kernel, how to duplicate, the setup, if the problem is new or old and when did you notice: covered in 'Reporting issues', especially in Step-by-step guide how to report issues to the kernel maintainers. Refer to 'Reporting issues'. - duplicate kernel bug reports exactly: covered in 'Reporting issues', especially in Write and send the report. Refer to 'Reporting issues'. - read 'Bug hunting': keep this reference. Refer to 'Bug hunting'. - compile the kernel with CONFIG_KALLSYMS: covered in 'Reporting issues', especially in Decode failure messages. Refer to 'Reporting issues'. - alternatively, use ksymoops: ksymoops at the mentioned URL seems not to be maintained anymore. It was released roughly once a year until version 2.4.11 in 2005, but has not seen a new release since then. The information in ./scripts/ksymoops/README is from 1999, and does not give more insight on its actual maintenance state either. Ksymoops is mentioned as system utility in changes.rst, but also not recommended there. Drop the explanation on using ksymoops. - alternatively, lookup dump manually with the EIP and nm to determine the function in which the kernel crashes: this method seems already a quite advanced and low-level debugging method. Even all the further references on bug hunting and debugging do not mention it. Drop this alternative method and limit mentioning methods explained in the other existing kernel documentation. - read 'Reporting issues': keep this reference. Refer to 'Reporting issues'. - use gdb for debugging: some specific details, e.g., edit arch/x86/Makefile, are probably outdated or limited to one (historic important) setup. Using gdb is covered in 'Bug hunting', 'Debugging kernel and modules via gdb' and 'Using kgdb, kdb and the kernel debugger internals'. Refer to those three documents. Overall, it is sufficient to refer to reporting-issues.rst, bug-hunting.rst, gdb-kernel-debugging.rst and kgdb.rst and this way cover the existing suggestions. 'Reporting issues' is quite new and probably up to date. 'Bug hunting', 'Debugging kernel and modules via gdb' and 'Using kgdb, kdb and the kernel debugger internals' might need some revisit and update, but they are generally in an acceptable state for referring to them. Replace the existing suggestions by reference to other existing kernel documentation covering those suggestions---partly even nicely summarized and then explained in greater detail.

2022-09-27docs: admin-guide: do not mention the 'run a.out user programs' featureLukas Bulwahn
Running a.out user programs with the latest kernel release is a very rare and uncommon use case nowadays. The support of a.out user programs is only remaining for the alpha architecture and is not defined and activated in the architecture's Kconfig (so even the activation of this support requires to modify the Kconfig file and not just kernel build configuration). The discussion on a.out support in 2019 (see Link) shows that the support of a.out user programs is just remaining for a special corner case from some (alpha architecture) users. There is no need to point out and mention this special feature to the general audience of kernel users. Delete the reference to this historic and special feature.

2022-09-27docs/conf.py: Respect env variable SPHINX_IMGMATHAkira Yokosawa
On some distros with coarse-grained packaging policy, dvipng is installed along with latex. In such cases, math rendering will use imgmath by default. It is possible to override the choice by specifying the option string of "-D html_math_renderer='mathjax'" to sphinx-build (Sphinx >= 1.8). To provide developers an easier-to-use knob, add code for an env variable "SPHINX_IMGMATH" which overrides the automatic choice of math renderer for html docs.

2022-09-27docs/conf.py: Treat mathjax as fallback math rendererAkira Yokosawa
Currently, math expressions using the "math::" directive or the ":math:" role of Sphinx need the imgmath extension for proper rendering in html and epub builds. imgmath requires dvipng (and latex). Otherwise, "make htmldocs" will complain of missing commands. As a matter of fact, the mathjax extension is loaded by default since Sphinx v1.8 and it is good enough for html docs without any dependency on texlive packages. Stop loading the imgmath extension for html docs unless requirements for imgmath are met. To find out whether required commands are available, add a helper find_command(), which is a wrapper of shutil.which(). For epub docs, keep the same behavior of always loading imgmath.

2022-09-27libbpf: Don't require full struct enum64 in UAPI headersAndrii Nakryiko
Drop the requirement for system-wide kernel UAPI headers to provide full struct btf_enum64 definition. This is an unexpected requirement that slipped in libbpf 1.0 and put unnecessary pressure ([0]) on users to have a bleeding-edge kernel UAPI header from unreleased Linux 6.0. To achieve this, we forward declare struct btf_enum64. But that's not enough as there is btf_enum64_value() helper that expects to know the layout of struct btf_enum64. So we get a bit creative with reinterpreting memory layout as array of __u32 and accesing lo32/hi32 fields as array elements. Alternative way would be to have a local pointer variable for anonymous struct with exactly the same layout as struct btf_enum64, but that gets us into C++ compiler errors complaining about invalid type casts. So play it safe, if ugly.

2022-09-27ice: xsk: change batched Tx descriptor cleaningMaciej Fijalkowski
AF_XDP Tx descriptor cleaning in ice driver currently works in a "lazy" way - descriptors are not cleaned immediately after send. We rather hold on with cleaning until we see that free space in ring drops below particular threshold. This was supposed to reduce the amount of unnecessary work related to cleaning and instead of keeping the ring empty, ring was rather saturated. In AF_XDP realm cleaning Tx descriptors implies producing them to CQ. This is a way of letting know user space that particular descriptor has been sent, as John points out in [0]. We tried to implement serial descriptor cleaning which would be used in conjunction with batched cleaning but it made code base more convoluted and probably harder to maintain in future. Therefore we step away from batched cleaning in a current form in favor of an approach where we set RS bit on every last descriptor from a batch and clean always at the beginning of ice_xmit_zc(). This means that we give up a bit of Tx performance, but this doesn't hurt l2fwd scenario which is way more meaningful than txonly as this can be treaten as AF_XDP based packet generator. l2fwd is not hurt due to the fact that Tx side is much faster than Rx and Rx is the one that has to catch Tx up. FWIW Tx descriptors are still produced in a batched way.

2022-09-27net: ethernet: mtk_eth_soc: fix usage of foe_entry_sizeDaniel Golle
As sizeof(hwe->data) can now longer be used as the actual size depends on foe_entry_size, in commit 9d8cb4c096ab02 ("net: ethernet: mtk_eth_soc: add foe_entry_size to mtk_eth_soc") the use of sizeof(hwe->data) is hence replaced. However, replacing it with ppe->eth->soc->foe_entry_size is wrong as foe_entry_size represents the size of the whole descriptor and not just the 'data' field. Fix this by subtracing the size of the only other field in the struct 'ib1', so we actually end up with the correct size to be copied to the data field.

2022-09-27Input: snvs_pwrkey - fix SNVS_HPVIDR1 register addressSebastian Krzyszkowiak
Both i.MX6 and i.MX8 reference manuals list 0xBF8 as SNVS_HPVIDR1 (chapters 57.9 and 6.4.5 respectively). Without this, trying to read the revision number results in 0 on all revisions, causing the i.MX6 quirk to apply on all platforms, which in turn causes the driver to synthesise power button release events instead of passing the real one as they happen even on platforms like i.MX8 where that's not wanted.

In commit 19e8b701e258 ("a.out: Stop building a.out/osf1 support on alpha and m68k") the last users of a.out were disabled. As nothing has turned up to cause this change to be reverted, let's remove the code implementing a.out support as well. There may be userspace users of the uapi bits left so the uapi headers have been left untouched. Signed-off-by: "Eric W.

Skip selftests that require EPT support in the VM when it is not available. For example, if running on a machine where kvm_intel.ept=N since KVM does not offer EPT support to guests if EPT is not supported on the host. This commit causes vmx_dirty_log_test to be skipped instead of failing on hosts where kvm_intel.ept=N.

2022-09-27mmc: hsq: Fix data stomping during mmc recoveryWenchao Chen
The block device uses multiple queues to access emmc. There will be up to 3 requests in the hsq of the host. The current code will check whether there is a request doing recovery before entering the queue, but it will not check whether there is a request when the lock is issued. The request is in recovery mode. If there is a request in recovery, then a read and write request is initiated at this time, and the conflict between the request and the recovery request will cause the data to be trampled.

2022-09-27Merge branch 'net-openvswitch-metering-and-conntrack-in-userns'Paolo Abeni
Michael Weiß says: ==================== net: openvswitch: metering and conntrack in userns Currently using openvswitch in a non-initial user namespace, e.g., an unprivileged container, is possible but without metering and conntrack support. This is due to the restriction of the corresponding Netlink interfaces to the global CAP_NET_ADMIN. This simple patches switch from GENL_ADMIN_PERM to GENL_UNS_ADMIN_PERM in several cases to allow this also for the unprivileged container use case. We tested this for unprivileged containers created by the container manager of GyroidOS (gyroidos.github.io). However, for other container managers such as LXC or systemd which provide unprivileged containers this should be apply equally. ==================== Link: https://lore.kernel.org/r/20220923133820.993725-1-michael.weiss@aisec.fraunhofer.de Signed-off-by: Paolo Abeni <pabeni@redhat.com>
