Due to problem reports in the past SG and TSO/TSO6 are disabled per default. It's not fully clear which chip versions are affected, so we may impact also users of unaffected chip versions, unless they know how to use ethtool for enabling SG/TSO/TSO6.

2024-10-14bcachefs: Fix sysfs warning in fstests generic/730,731Kent Overstreet
sysfs warns if we're removing a symlink from a directory that's no longer in sysfs; this is triggered by fstests generic/730, which simulates hot removal of a block device. This patch is however not a correct fix, since checking kobj->state_in_sysfs on a kobj owned by another subsystem is racy. A better fix would be to add the appropriate check to sysfs_remove_link() - and sysfs_create_link() as well. But kobject_add_internal()/kobject_del() do not as of today have locking that would support that. Note that the block/holder.c code appears to be subject to this race as well.

2024-10-14sched/fair: Fix external p->on_rq usersPeter Zijlstra
Sean noted that ever since commit 152e11f6df29 ("sched/fair: Implement delayed dequeue") KVM's preemption notifiers have started mis-classifying preemption vs blocking. Notably p->on_rq is no longer sufficient to determine if a task is runnable or blocked -- the aforementioned commit introduces tasks that remain on the runqueue even through they will not run again, and should be considered blocked for many cases. Add the task_is_runnable() helper to classify things and audit all external users of the p->on_rq state. Also add a few comments.

2024-10-14sched/psi: Fix mistaken CPU pressure indication after corrupted task state bugJohannes Weiner
Since sched_delayed tasks remain queued even after blocking, the load balancer can migrate them between runqueues while PSI considers them to be asleep. As a result, it misreads the migration requeue followed by a wakeup as a double queue: psi: inconsistent task state! task=... cpu=... psi_flags=4 clear=. set=4 First, call psi_enqueue() after p->sched_class->enqueue_task(). A wakeup will clear p->se.sched_delayed while a migration will not, so psi can use that flag to tell them apart. Then teach psi to migrate any "sleep" state when delayed-dequeue tasks are being migrated. Delayed-dequeue tasks can be revived by ttwu_runnable(), which will call down with a new ENQUEUE_DELAYED. Instead of further complicating the wakeup conditional in enqueue_task(), identify migration contexts instead and default to wakeup handling for all other cases. It's not just the warning in dmesg, the task state corruption causes a permanent CPU pressure indication, which messes with workload/machine health monitoring.

2024-10-13bcachefs: Handle race between stripe reuse, invalidate_stripe_to_devKent Overstreet
When creating a new stripe, we may reuse an existing stripe that has some empty and some nonempty blocks. Generally, the existing stripe won't change underneath us - except for block sector counts, which we copy to the new key in ec_stripe_key_update. But the device removal path can now invalidate stripe pointers to a device, and that can race with stripe reuse. Change ec_stripe_key_update() to check for and resolve this inconsistency.

2024-10-13cfi: fix conditions for HAVE_CFI_ICALL_NORMALIZE_INTEGERSAlice Ryhl
The HAVE_CFI_ICALL_NORMALIZE_INTEGERS option has some tricky conditions when KASAN or GCOV are turned on, as in that case we need some clang and rustc fixes [1][2] to avoid boot failures. The intent with the current setup is that you should be able to override the check and turn on the option if your clang/rustc has the fix. However, this override does not work in practice. Thus, use the new RUSTC_LLVM_VERSION to correctly implement the check for whether the fix is available. Additionally, remove KASAN_HW_TAGS from the list of incompatible options. The CFI_ICALL_NORMALIZE_INTEGERS option is incompatible with KASAN because LLVM will emit some constructors when using KASAN that are assigned incorrect CFI tags. These constructors are emitted due to use of -fsanitize=kernel-address or -fsanitize=kernel-hwaddress that are respectively passed when KASAN_GENERIC or KASAN_SW_TAGS are enabled. However, the KASAN_HW_TAGS option relies on hardware support for MTE instead and does not pass either flag. (Note also that KASAN_HW_TAGS does not `select CONSTRUCTORS`.)

2024-10-13net: ethtool: Add new parameters and a function to support EPLDanielle Ratson
In the CMIS specification for pluggable modules, LPL (Local Payload) and EPL (Extended Payload) are two types of data payloads used for managing various functions and features of the module. EPL payloads are used for more complex and extensive management functions that require a larger amount of data, so writing firmware blocks using EPL is much more efficient. Currently, only LPL payload is supported for writing firmware blocks to the module. Add EPL related parameters to the function ethtool_cmis_cdb_compose_args() and add a specific function for calculating the maximum allowable length extension for EPL. Both will be used in the next patch to add support for writing firmware blocks using EPL.

2024-10-13parport: Proper fix for array out-of-bounds accessTakashi Iwai
The recent fix for array out-of-bounds accesses replaced sprintf() calls blindly with snprintf(). However, since snprintf() returns the would-be-printed size, not the actually output size, the length calculation can still go over the given limit. Use scnprintf() instead of snprintf(), which returns the actually output letters, for addressing the potential out-of-bounds access properly.
