2022-04-07SUNRPC: Fix the svc_deferred_event trace classChuck Lever
Fix a NULL deref crash that occurs when an svc_rqst is deferred while the sunrpc tracing subsystem is enabled. svc_revisit() sets dr->xprt to NULL, so it can't be relied upon in the tracepoint to provide the remote's address. Unfortunately we can't revert the "svc_deferred_class" hunk in commit ece200ddd54b ("sunrpc: Save remote presentation address in svc_xprt for trace events") because there is now a specific check of event format specifiers for unsafe dereferences. The warning that check emits is: event svc_defer_recv has unsafe dereference of argument 1 A "%pISpc" format specifier with a "struct sockaddr *" is indeed flagged by this check. Instead, take the brute-force approach used by the svcrdma_qp_error tracepoint. Convert the dr::addr field into a presentation address in the TP_fast_assign() arm of the trace event, and store that as a string. This fix can be backported to -stable kernels. In the meantime, commit c6ced22997ad ("tracing: Update print fmt check to handle new __get_sockaddr() macro") is now in v5.18, so this wonky fix can be replaced with __sockaddr() and friends properly during the v5.19 merge window.

2022-04-07mm/rmap: Fix handling of hugetlbfs pages in page_vma_mapped_walkzhenwei pi
page_mapped_in_vma() sets nr_pages to 1, which is usually correct as we only want to know about the precise page and not about other pages in the folio. However, hugetlbfs does want to know about the entire hpage, and using nr_pages to get the size of the hpage is wrong. We could change page_mapped_in_vma() to special-case hugetlbfs pages, but it's better to ignore nr_pages in page_vma_mapped_walk() and get the size from the VMA instead.

2022-04-07mm/huge_memory: Avoid calling pmd_page() on a non-leaf PMDMatthew Wilcox (Oracle)
Calling try_to_unmap() with TTU_SPLIT_HUGE_PMD and a folio that's not mapped by a PMD causes oopses on arm64 because we now call page_folio() on an invalid page. pmd_page() returns a valid page for non-leaf PMDs on some architectures, so this bug escaped testing before now. Fix this bug by delaying the call to pmd_page() until after we know the PMD is a leaf.

2022-04-07selftests: KVM: Free the GIC FD when cleaning up in arch_timerOliver Upton
In order to correctly destroy a VM, all references to the VM must be freed. The arch_timer selftest creates a VGIC for the guest, which itself holds a reference to the VM. Close the GIC FD when cleaning up a VM.

2022-04-07selftests: KVM: Don't leak GIC FD across dirty log test iterationsOliver Upton
dirty_log_perf_test instantiates a VGICv3 for the guest (if supported by hardware) to reduce the overhead of guest exits. However, the test does not actually close the GIC fd when cleaning up the VM between test iterations, meaning that the VM is never actually destroyed in the kernel. While this is generally a bad idea, the bug was detected from the kernel spewing about duplicate debugfs entries as subsequent VMs happen to reuse the same FD even though the debugfs directory is still present. Abstract away the notion of setup/cleanup of the GIC FD from the test by creating arch-specific helpers for test setup/cleanup. Close the GIC FD on VM cleanup and do nothing for the other architectures.

2022-04-07KVM: Don't create VM debugfs files outside of the VM directoryOliver Upton
Unfortunately, there is no guarantee that KVM was able to instantiate a debugfs directory for a particular VM. To that end, KVM shouldn't even attempt to create new debugfs files in this case. If the specified parent dentry is NULL, debugfs_create_file() will instantiate files at the root of debugfs. For arm64, it is possible to create the vgic-state file outside of a VM directory, the file is not cleaned up when a VM is destroyed. Nonetheless, the corresponding struct kvm is freed when the VM is destroyed. Nip the problem in the bud for all possible errant debugfs file creations by initializing kvm->debugfs_dentry to -ENOENT. In so doing, debugfs_create_file() will fail instead of creating the file in the root directory.

2022-04-07KVM: selftests: get-reg-list: Add KVM_REG_ARM_FW_REG(3)Andrew Jones
When testing a kernel with commit a5905d6af492 ("KVM: arm64: Allow SMCCC_ARCH_WORKAROUND_3 to be discovered and migrated") get-reg-list output vregs: Number blessed registers: 234 vregs: Number registers: 238 vregs: There are 1 new registers. Consider adding them to the blessed reg list with the following lines: KVM_REG_ARM_FW_REG(3), vregs: PASS ... That output inspired two changes: 1) add the new register to the blessed list and 2) explain why "Number registers" is actually four larger than "Number blessed registers" (on the system used for testing), even though only one register is being stated as new. The reason is that some registers are host dependent and they get filtered out when comparing with the blessed list. The system used for the test apparently had three filtered registers.

2022-04-06drivers: net: slip: fix NPD bug in sl_tx_timeout()Duoming Zhou
When a slip driver is detaching, the slip_close() will act to cleanup necessary resources and sl->tty is set to NULL in slip_close(). Meanwhile, the packet we transmit is blocked, sl_tx_timeout() will be called. Although slip_close() and sl_tx_timeout() use sl->lock to synchronize, we don`t judge whether sl->tty equals to NULL in sl_tx_timeout() and the null pointer dereference bug will happen. (Thread 1) | (Thread 2) | slip_close() | spin_lock_bh(&sl->lock) | ... ... | sl->tty = NULL //(1) sl_tx_timeout() | spin_unlock_bh(&sl->lock) spin_lock(&sl->lock); | ... | ... tty_chars_in_buffer(sl->tty)| if (tty->ops->..) //(2) | ... | synchronize_rcu() We set NULL to sl->tty in position (1) and dereference sl->tty in position (2). This patch adds check in sl_tx_timeout(). If sl->tty equals to NULL, sl_tx_timeout() will goto out.

The megaraid_sas driver supports single LUN for RAID devices. That is LUN 0. All other LUNs are unsupported. When a device scan on a logical target with invalid LUN number is invoked through sysfs, that target ends up getting removed. Add LUN ID validation in the slave destroy function to avoid the target deletion.
