tracing/treewide: Remove second parameter of __assign_str()

2024-05-23T00:14:47Z

With the rework of how the __string() handles dynamic strings where it saves off the source string in field in the helper structure[1], the assignment of that value to the trace event field is stored in the helper value and does not need to be passed in again. This means that with: __string(field, mystring) Which use to be assigned with __assign_str(field, mystring), no longer needs the second parameter and it is unused. With this, __assign_str() will now only get a single parameter. There's over 700 users of __assign_str() and because coccinelle does not handle the TRACE_EVENT() macro I ended up using the following sed script: git grep -l __assign_str | while read a ; do sed -e 's/$__assign_str([^,]*[^ ,]$ *,[^;]*/\1)/' $a > /tmp/test-file; mv /tmp/test-file $a; done I then searched for __assign_str() that did not end with ';' as those were multi line assignments that the sed script above would fail to catch. Note, the same updates will need to be done for: __assign_str_len() __assign_rel_str() __assign_rel_str_len() I tested this with both an allmodconfig and an allyesconfig (build only for both).

Pull KVM updates from Paolo Bonzini: "ARM: - Move a lot of state that was previously stored on a per vcpu basis into a per-CPU area, because it is only pertinent to the host while the vcpu is loaded. This results in better state tracking, and a smaller vcpu structure. - Add full handling of the ERET/ERETAA/ERETAB instructions in nested virtualisation. The last two instructions also require emulating part of the pointer authentication extension. As a result, the trap handling of pointer authentication has been greatly simplified. - Turn the global (and not very scalable) LPI translation cache into a per-ITS, scalable cache, making non directly injected LPIs much cheaper to make visible to the vcpu. - A batch of pKVM patches, mostly fixes and cleanups, as the upstreaming process seems to be resuming. Fingers crossed! - Allocate PPIs and SGIs outside of the vcpu structure, allowing for smaller EL2 mapping and some flexibility in implementing more or less than 32 private IRQs. - Purge stale mpidr_data if a vcpu is created after the MPIDR map has been created. - Preserve vcpu-specific ID registers across a vcpu reset. - Various minor cleanups and improvements. LoongArch: - Add ParaVirt IPI support - Add software breakpoint support - Add mmio trace events support RISC-V: - Support guest breakpoints using ebreak - Introduce per-VCPU mp_state_lock and reset_cntx_lock - Virtualize SBI PMU snapshot and counter overflow interrupts - New selftests for SBI PMU and Guest ebreak - Some preparatory work for both TDX and SNP page fault handling. This also cleans up the page fault path, so that the priorities of various kinds of fauls (private page, no memory, write to read-only slot, etc.) are easier to follow. x86: - Minimize amount of time that shadow PTEs remain in the special REMOVED_SPTE state. This is a state where the mmu_lock is held for reading but concurrent accesses to the PTE have to spin; shortening its use allows other vCPUs to repopulate the zapped region while the zapper finishes tearing down the old, defunct page tables. - Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID field, which is defined by hardware but left for software use. This lets KVM communicate its inability to map GPAs that set bits 51:48 on hosts without 5-level nested page tables. Guest firmware is expected to use the information when mapping BARs; this avoids that they end up at a legal, but unmappable, GPA. - Fixed a bug where KVM would not reject accesses to MSR that aren't supposed to exist given the vCPU model and/or KVM configuration. - As usual, a bunch of code cleanups. x86 (AMD): - Implement a new and improved API to initialize SEV and SEV-ES VMs, which will also be extendable to SEV-SNP. The new API specifies the desired encryption in KVM_CREATE_VM and then separately initializes the VM. The new API also allows customizing the desired set of VMSA features; the features affect the measurement of the VM's initial state, and therefore enabling them cannot be done tout court by the hypervisor. While at it, the new API includes two bugfixes that couldn't be applied to the old one without a flag day in userspace or without affecting the initial measurement. When a SEV-ES VM is created with the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are rejected once the VMSA has been encrypted. Also, the FPU and AVX state will be synchronized and encrypted too. - Support for GHCB version 2 as applicable to SEV-ES guests. This, once more, is only accessible when using the new KVM_SEV_INIT2 flow for initialization of SEV-ES VMs. x86 (Intel): - An initial bunch of prerequisite patches for Intel TDX were merged. They generally don't do anything interesting. The only somewhat user visible change is a new debugging mode that checks that KVM's MMU never triggers a #VE virtualization exception in the guest. - Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig VM-Exit to L1, as per the SDM. Generic: - Use vfree() instead of kvfree() for allocations that always use vcalloc() or __vcalloc(). - Remove .change_pte() MMU notifier - the changes to non-KVM code are small and Andrew Morton asked that I also take those through the KVM tree. The callback was only ever implemented by KVM (which was also the original user of MMU notifiers) but it had been nonfunctional ever since calls to set_pte_at_notify were wrapped with invalidate_range_start and invalidate_range_end... in 2012. Selftests: - Enhance the demand paging test to allow for better reporting and stressing of UFFD performance. - Convert the steal time test to generate TAP-friendly output. - Fix a flaky false positive in the xen_shinfo_test due to comparing elapsed time across two different clock domains. - Skip the MONITOR/MWAIT test if the host doesn't actually support MWAIT. - Avoid unnecessary use of "sudo" in the NX hugepage test wrapper shell script, to play nice with running in a minimal userspace environment. - Allow skipping the RSEQ test's sanity check that the vCPU was able to complete a reasonable number of KVM_RUNs, as the assert can fail on a completely valid setup. If the test is run on a large-ish system that is otherwise idle, and the test isn't affined to a low-ish number of CPUs, the vCPU task can be repeatedly migrated to CPUs that are in deep sleep states, which results in the vCPU having very little net runtime before the next migration due to high wakeup latencies. - Define _GNU_SOURCE for all selftests to fix a warning that was introduced by a change to kselftest_harness.h late in the 6.9 cycle, and because forcing every test to #define _GNU_SOURCE is painful. - Provide a global pseudo-RNG instance for all tests, so that library code can generate random, but determinstic numbers. - Use the global pRNG to randomly force emulation of select writes from guest code on x86, e.g. to help validate KVM's emulation of locked accesses. - Allocate and initialize x86's GDT, IDT, TSS, segments, and default exception handlers at VM creation, instead of forcing tests to manually trigger the related setup.
