2021-11-13perf tools: Add more weak libbpf functionsJiri Olsa1-0/+27
We hit the window where perf uses libbpf functions, that did not make it to the official libbpf release yet and it's breaking perf build with dynamicly linked libbpf. Fixing this by providing the new interface as weak functions which calls the original libbpf functions. Fortunatelly the changes were just renames.

2021-11-13perf bpf: Avoid memory leak from perf_env__insert_btf()Ian Rogers3-3/+10
perf_env__insert_btf() doesn't insert if a duplicate BTF id is encountered and this causes a memory leak. Modify the function to return a success/error value and then free the memory if insertion didn't happen. v2. Adds a return -1 when the insertion error occurs in perf_env__fetch_btf. This doesn't affect anything as the result is never checked.

The head pointer of the AUX buffer managed by the arm_spe_pmu.c driver is not monotonically increasing, therefore the find_snapshot callback is needed in order to find the trace data within the AUX buffer and avoid wasting space in the perf.data file. The pointer is assumed to have wrapped if the buffer contains non-zero data at the end. If it has wrapped, the entire contents of the AUX buffer are stored in the perf.data file. Otherwise only the data up to the head pointer is stored.

2021-11-13perf expr: Add source_count for aggregating eventsIan Rogers8-12/+66
Events like uncore_imc/cas_count_read/ on Skylake open multiple events and then aggregate in the metric leader. To determine the average value per event the number of these events is needed. Add a source_count function that returns this value by counting the number of events with the given metric leader. For most events the value is 1 but for uncore_imc/cas_count_read/ it can yield values like 6. Add a generic test, but manually tested with a test metric that uses the function.

2021-11-13parisc/entry: fix trace test in syscall exit pathSven Schnelle1-1/+1
commit 8779e05ba8aa ("parisc: Fix ptrace check on syscall return") fixed testing of TI_FLAGS. This uncovered a bug in the test mask. syscall_restore_rfi is only used when the kernel needs to exit to usespace with single or block stepping and the recovery counter enabled. The test however used _TIF_SYSCALL_TRACE_MASK, which includes a lot of bits that shouldn't be tested here. Fix this by using TIF_SINGLESTEP and TIF_BLOCKSTEP directly. I encountered this bug by enabling syscall tracepoints. Both in qemu and on real hardware. As soon as i enabled the tracepoint (sys_exit_read, but i guess it doesn't really matter which one), i got random page faults in userspace almost immediately.

2021-11-13parisc: Flush kernel data mapping in set_pte_at() when installing pte for ↵John David Anglin2-4/+10
user page For years, there have been random segmentation faults in userspace on SMP PA-RISC machines. It occurred to me that this might be a problem in set_pte_at(). MIPS and some other architectures do cache flushes when installing PTEs with the present bit set. Here I have adapted the code in update_mmu_cache() to flush the kernel mapping when the kernel flush is deferred, or when the kernel mapping may alias with the user mapping. This simplifies calls to update_mmu_cache(). I also changed the barrier in set_pte() from a compiler barrier to a full memory barrier. I know this change is not sufficient to fix the problem. It might not be needed. I have had a few days of operation with 5.14.16 to 5.15.1 and haven't seen any random segmentation faults on rp3440 or c8000 so far.

2021-11-13parisc: Fix backtrace to always include init funtion namesHelge Deller1-1/+2
I noticed that sometimes at kernel startup the backtraces did not included the function names of init functions. Their address were not resolved to function names and instead only the address was printed. Debugging shows that the culprit is is_ksym_addr() which is called by the backtrace functions to check if an address belongs to a function in the kernel. The problem occurs only for CONFIG_KALLSYMS_ALL=y. When looking at is_ksym_addr() one can see that for CONFIG_KALLSYMS_ALL=y the function only tries to resolve the address via is_kernel() function, which checks like this: if (addr >= _stext && addr <= _end) return 1; On parisc the init functions are located before _stext, so this check fails. Other platforms seem to have all functions (including init functions) behind _stext. The following patch moves the _stext symbol at the beginning of the kernel and thus includes the init section. This fixes the check and does not seem to have any negative side effects on where the kernel mapping happens in the map_pages() function in arch/parisc/mm/init.c.

2021-11-13Revert "mm: shmem: don't truncate page if memory failure happens"Linus Torvalds3-51/+6
This reverts commit b9d02f1bdd98f38e6e5ecacc9786a8f58f3f8b2c. The error handling of that patch was fundamentally broken, and it needs to be entirely re-done. For example, in shmem_write_begin() it would call shmem_getpage(), then ignore the error return from that, and look at the page pointer contents instead. And in shmem_read_mapping_page_gfp(), the patch tested PageHWPoison() on a page pointer that two lines earlier had potentially been set as an error pointer. These issues could be individually fixed, but when it has this many issues, I'm just reverting it instead of waiting for fixes.
