2023-02-14EDAC/amd64: Shut up an -Werror,-Wsometimes-uninitialized clang false positiveYazen Ghannam
Reportedly, clang cannot do interprocedural analysis: https://lore.kernel.org/r/20230213-amd64_edac-wsometimes-uninitialized-v1-1-5bde32b89e02@kernel.org and see that those arguments won't be used uninitialized. So, yeah, the code's fine even without this. Normally, such a "fix" won't be applied but that warning gets automatically enabled in -Wall builds and when CONFIG_WERROR is set in allmodconfig builds, the build fails. So shut it up with a minimal fix as this code will see more reorganization very soon.

2023-02-09EDAC/amd64: Remove early_channel_count()Yazen Ghannam
The early_channel_count() function seems to have been useful in the past for knowing how many EDAC mci structures to populate. However, this is no longer needed as the maximum channel count for a system is used instead. Remove the early_channel_count() helper functions and related code. Use the size of the channel layer when iterating over channel structures.

2023-02-09EDAC/amd64: Remove PCI Function 0Yazen Ghannam
PCI Function 0 is used on Family 17h and later only to read the "dhar" value. This value is printed and provided through a module-specific debug sysfs file. The value is not used for any Family 17h and later code, and it does not have any apparent debug value on these systems. Remove "dhar", Function 0 PCI IDs, and all related code.

2023-02-09EDAC/amd64: Remove scrub rate control for Family 17h and laterYazen Ghannam
The scrub registers on AMD Family 17h and later may be inaccessible to the OS. Furthermore, hardware designers recommend that the scrubbing feature is managed by the firmware. Remove support for the sdram_scrub_rate interface for AMD Family 17h systems and later by not setting the scrub function pointers. The EDAC MC core will then not expose the scrub files in sysfs.

2023-02-08EDAC/i10nm: Add driver decoder for Sapphire Rapids serverYouquan Song
Intel SDM (December 2022) vol3B 17.13.2 contains IMC MC error codes for Sapphire Rapids. Current i10nm_edac only supports firmware decoder (ACPI DSM methods) for Sapphire Rapids. So add the driver decoder (decoding DDR memory errors via extracting error information from the IMC MC error codes) for Sapphire Rapids for better decoding performance.

2023-01-06tpm: Allow system suspend to continue when TPM suspend failsJason A. Donenfeld
TPM 1 is sometimes broken across system suspends, due to races or locking issues or something else that haven't been diagnosed or fixed yet, most likely having to do with concurrent reads from the TPM's hardware random number generator driver. These issues prevent the system from actually suspending, with errors like: tpm tpm0: A TPM error (28) occurred continue selftest ... tpm tpm0: A TPM error (28) occurred attempting get random ... tpm tpm0: Error (28) sending savestate before suspend tpm_tis 00:08: PM: __pnp_bus_suspend(): tpm_pm_suspend+0x0/0x80 returns 28 tpm_tis 00:08: PM: dpm_run_callback(): pnp_bus_suspend+0x0/0x10 returns 28 tpm_tis 00:08: PM: failed to suspend: error 28 PM: Some devices failed to suspend, or early wake event detected This issue was partially fixed by 23393c646142 ("char: tpm: Protect tpm_pm_suspend with locks"), in a last minute 6.1 commit that Linus took directly because the TPM maintainers weren't available. However, it seems like this just addresses the most common cases of the bug, rather than addressing it entirely. So there are more things to fix still, apparently. In lieu of actually fixing the underlying bug, just allow system suspend to continue, so that laptops still go to sleep fine. Later, this can be reverted when the real bug is fixed.

2023-01-06hfs/hfsplus: avoid WARN_ON() for sanity check, use proper error handlingLinus Torvalds
Commit 55d1cbbbb29e ("hfs/hfsplus: use WARN_ON for sanity check") fixed a build warning by turning a comment into a WARN_ON(), but it turns out that syzbot then complains because it can trigger said warning with a corrupted hfs image. The warning actually does warn about a bad situation, but we are much better off just handling it as the error it is. So rather than warn about us doing bad things, stop doing the bad things and return -EIO. While at it, also fix a memory leak that was introduced by an earlier fix for a similar syzbot warning situation, and add a check for one case that historically wasn't handled at all (ie neither comment nor subsequent WARN_ON).

This makes the output using BPF counters match the output without using it, which was the intention all along, the output should be the same using --bpf-counters or not. - Fix 'perf lock contention' core dump related to not finding the "__sched_text_end" symbol on s/390. - Fix build failure when HEAD is signed: exclude the signature from the version string. - Add missing closedir() calls to in perf_data__open_dir(), plugging a fd leak. * tag 'perf-tools-fixes-for-v6.2-1-2023-01-06' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: perf tools: Fix build on uClibc systems by adding missing sys/types.h include perf stat: Fix handling of --for-each-cgroup with --bpf-counters to match non BPF mode perf stat: Fix handling of unsupported cgroup events when using BPF counters perf test record_probe_libc_inet_pton: Fix test on s/390 where 'text_to_binary_address' now appears on the backtrace perf lock contention: Fix core dump related to not finding the "__sched_text_end" symbol on s/390 perf build: Don't propagate subdir to submakes for install_headers perf test record_probe_libc_inet_pton: Fix failure due to extra inet_pton() backtrace in glibc >= 2.35 perf tools: Fix segfault when trying to process tracepoints in perf.data and not linked with libtraceevent perf tools: Don't include signature in version strings perf help: Use HAVE_LIBTRACEEVENT to filter out unsupported commands perf tools riscv: Fix build error on riscv due to missing header for 'struct perf_sample' perf tools: Fix resources leak in perf_data__open_dir()

2023-01-06usb: dwc3: gadget: Ignore End Transfer delay on teardownThinh Nguyen
If we delay sending End Transfer for Setup TRB to be prepared, we need to check if the End Transfer was in preparation for a driver teardown/soft-disconnect. In those cases, just send the End Transfer command without delay. In the case of soft-disconnect, there's a very small chance the command may not go through immediately. But should it happen, the Setup TRB will be prepared during the polling of the controller halted state, allowing the command to go through then. In the case of disabling endpoint due to reconfiguration (e.g. set_interface(alt-setting) or usb reset), then it's driven by the host. Typically the host wouldn't immediately cancel the control request and send another control transfer to trigger the End Transfer command timeout.

2023-01-05riscv, kprobes: Stricter c.jr/c.jalr decodingBjörn Töpel
In the compressed instruction extension, c.jr, c.jalr, c.mv, and c.add is encoded the following way (each instruction is 16b): ---+-+-----------+-----------+-- 100 0 rs1[4:0]!=0 00000 10 : c.jr 100 1 rs1[4:0]!=0 00000 10 : c.jalr 100 0 rd[4:0]!=0 rs2[4:0]!=0 10 : c.mv 100 1 rd[4:0]!=0 rs2[4:0]!=0 10 : c.add The following logic is used to decode c.jr and c.jalr: insn & 0xf007 == 0x8002 => instruction is an c.jr insn & 0xf007 == 0x9002 => instruction is an c.jalr When 0xf007 is used to mask the instruction, c.mv can be incorrectly decoded as c.jr, and c.add as c.jalr.

2023-01-05lib/scatterlist: Fix to merge contiguous pages into the last SG properlyYishai Hadas
When sg_alloc_append_table_from_pages() calls to pages_are_mergeable() in its 'sgt_append->prv' flow to check whether it can merge contiguous pages into the last SG, it passes the page arguments in the wrong order. The first parameter should be the next candidate page to be merged to the last page and not the opposite. The current code leads to a corrupted SG which resulted in OOPs and unexpected errors when non-contiguous pages are merged wrongly. Fix to pass the page parameters in the right order.
