2024-04-13dt-bindings: iio: imu: mpu6050: Improve i2c-gate disallow listLuca Weiss1-8/+9
Before all supported sensors except for MPU{9150,9250,9255} were not allowed to use i2c-gate in the bindings which excluded quite a few supported sensors where this functionality is supported. Switch the list of sensors to ones where the Linux driver explicitly disallows support for the auxiliary bus ("inv_mpu_i2c_aux_bus"). Since the driver is also based on "default: return true" this should scale better into the future.

2024-04-13Documentation: Mark the 'efivars' sysfs interface as removedTim Schumacher3-80/+13
The 'efivars' sysfs interface was removed in commit 0f5b2c69a4cb ("efi: vars: Remove deprecated 'efivars' sysfs interface"), but the ABI documentation was not updated properly. Strip down the documentation file for /sys/firmware/efi/vars to a very basic description of what the interface was about, add a section about the rough removal timeline, and inform the reader about the intended replacement.

2024-04-13dt-bindings: phy: rockchip,pcie3-phy: add rockchip,rx-common-refclk-modeNiklas Cassel1-0/+10
>From the RK3588 Technical Reference Manual, Part1, section 6.19 PCIe3PHY_GRF Register Description: "rxX_cmn_refclk_mode" RX common reference clock mode for lane X. This mode should be enabled only when the far-end and near-end devices are running with a common reference clock. The hardware reset value for this field is 0x1 (enabled). Note that this register field is only available on RK3588, not on RK3568. The link training either fails or is highly unstable (link state will jump continuously between L0 and recovery) when this mode is enabled while using an endpoint running in Separate Reference Clock with No SSC (SRNS) mode or Separate Reference Clock with SSC (SRIS) mode. (Which is usually the case when using a real SoC as endpoint, e.g. the RK3588 PCIe controller can run in both Root Complex and Endpoint mode.) Add a rockchip specific property to enable/disable the rxX_cmn_refclk_mode per lane. (Since this PHY supports bifurcation.)

2024-04-12arm64: boot: Support Flat Image TreeSimon Glass1-0/+9
Add a script which produces a Flat Image Tree (FIT), a single file containing the built kernel and associated devicetree files. Compression defaults to gzip which gives a good balance of size and performance. The files compress from about 86MB to 24MB using this approach. The FIT can be used by bootloaders which support it, such as U-Boot and Linuxboot. It permits automatic selection of the correct devicetree, matching the compatible string of the running board with the closest compatible string in the FIT. There is no need for filenames or other workarounds. Add a 'make image.fit' build target for arm64, as well. The FIT can be examined using 'dumpimage -l'. This uses the 'dtbs-list' file but processes only .dtb files, ignoring the overlay .dtbo files. This features requires pylibfdt (use 'pip install libfdt'). It also requires compression utilities for the algorithm being used. Supported compression options are the same as the Image.xxx files. Use FIT_COMPRESSION to select an algorithm other than gzip. While FIT supports a ramdisk / initrd, no attempt is made to support this here, since it must be built separately from the Linux build.

Pull more bcachefs fixes from Kent Overstreet: "Notable user impacting bugs - On multi device filesystems, recovery was looping in btree_trans_too_many_iters(). This checks if a transaction has touched too many btree paths (because of iteration over many keys), and isuses a restart to drop unneeded paths. But it's now possible for some paths to exceed the previous limit without iteration in the interior btree update path, since the transaction commit will do alloc updates for every old and new btree node, and during journal replay we don't use the btree write buffer for locking reasons and thus those updates use btree paths when they wouldn't normally. - Fix a corner case in rebalance when moving extents on a durability=0 device. This wouldn't be hit when a device was formatted with durability=0 since in that case we'll only use it as a write through cache (only cached extents will live on it), but durability can now be changed on an existing device. - bch2_get_acl() could rarely forget to handle a transaction restart; this manifested as the occasional missing acl that came back after dropping caches. - Fix a major performance regression on high iops multithreaded write workloads (only since 6.9-rc1); a previous fix for a deadlock in the interior btree update path to check the journal watermark introduced a dependency on the state of btree write buffer flushing that we didn't want. - Assorted other repair paths and recovery fixes" * tag 'bcachefs-2024-04-10' of https://evilpiepirate.org/git/bcachefs: (25 commits) bcachefs: Fix __bch2_btree_and_journal_iter_init_node_iter() bcachefs: Kill read lock dropping in bch2_btree_node_lock_write_nofail() bcachefs: Fix a race in btree_update_nodes_written() bcachefs: btree_node_scan: Respect member.data_allowed bcachefs: Don't scan for btree nodes when we can reconstruct bcachefs: Fix check_topology() when using node scan bcachefs: fix eytzinger0_find_gt() bcachefs: fix bch2_get_acl() transaction restart handling bcachefs: fix the count of nr_freed_pcpu after changing bc->freed_nonpcpu list bcachefs: Fix gap buffer bug in bch2_journal_key_insert_take() bcachefs: Rename struct field swap to prevent macro naming collision MAINTAINERS: Add entry for bcachefs documentation Documentation: filesystems: Add bcachefs toctree bcachefs: JOURNAL_SPACE_LOW bcachefs: Disable errors=panic for BCH_IOCTL_FSCK_OFFLINE bcachefs: Fix BCH_IOCTL_FSCK_OFFLINE for encrypted filesystems bcachefs: fix rand_delete unit test bcachefs: fix ! vs ~ typo in __clear_bit_le64() bcachefs: Fix rebalance from durability=0 device bcachefs: Print shutdown journal sequence number ...
2024-04-11KVM: SEV: introduce KVM_SEV_INIT2 operationPaolo Bonzini1-3/+37
The idea that no parameter would ever be necessary when enabling SEV or SEV-ES for a VM was decidedly optimistic. In fact, in some sense it's already a parameter whether SEV or SEV-ES is desired. Another possible source of variability is the desired set of VMSA features, as that affects the measurement of the VM's initial state and cannot be changed arbitrarily by the hypervisor. Create a new sub-operation for KVM_MEMORY_ENCRYPT_OP that can take a struct, and put the new op to work by including the VMSA features as a field of the struct. The existing KVM_SEV_INIT and KVM_SEV_ES_INIT use the full set of supported VMSA features for backwards compatibility. The struct also includes the usual bells and whistles for future extensibility: a flags field that must be zero for now, and some padding at the end.

This corresponds to the NT syscall NtCreateSemaphore(). Semaphores are one of three types of object to be implemented in this driver, the others being mutexes and events. An NT semaphore contains a 32-bit counter, and is signaled and can be acquired when the counter is nonzero. The counter has a maximum value which is specified at creation time. The initial value of the semaphore is also specified at creation time. There are no restrictions on the maximum and initial value. Each object is exposed as an file, to which any number of fds may be opened. When all fds are closed, the object is deleted. Objects hold a pointer to the ntsync_device that created them. The device's reference count is driven by struct file.

2024-04-11tty/sysrq: Replay kernel log messages on consoles via sysrqSreenath Vijayan1-0/+9
When terminal is unresponsive, one cannot use dmesg to view the printk ring buffer messages. Also, syslog services may be disabled, especially on embedded systems, to check the messages after a reboot. In this scenario, replay the messages in printk ring buffer on consoles via sysrq by pressing sysrq+R. The console loglevel will determine which all kernel log messages are displayed. The messages will be displayed only when console_trylock() succeeds. Users could repeat the sysrq key when it fails. If the owner of console subsystem lock is stuck, repeating the key won't work.

2024-04-11x86/bugs: Clarify that syscall hardening isn't a BHI mitigationJosh Poimboeuf2-8/+6
While syscall hardening helps prevent some BHI attacks, there's still other low-hanging fruit remaining. Don't classify it as a mitigation and make it clear that the system may still be vulnerable if it doesn't have a HW or SW mitigation enabled.

2024-04-10docs: Detect variable fonts and suggest denylisting themAkira Yokosawa2-5/+11
Fedora and openSUSE has started deploying "variable font" [1] format Noto CJK fonts [2, 3]. "CJK" here stands for "Chinese, Japanese, and Korean". Unfortunately, XeTeX/XeLaTeX doesn't understand those fonts for historical reasons and builds of translations.pdf end up in errors if such fonts are present on the build host. To help developers work around the issue, add a script to check the presence of "variable font" Noto CJK fonts and to emit suggestions. The script is invoked in the error path of "make pdfdocs" so that the suggestions are made only when a PDF build actually fails. The first suggestion is to denylist those "variable font" files by activating a per-user and command-local fontconfig setting. For further info and backgrounds, please refer to the header comment of scripts/check-variable-font.sh newly added in this commit.
