git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull perf tools fixes from Arnaldo Carvalho de Melo: - Make 'perf kmem' cope with the removal of some kmem:kmem_cache_alloc_node and kmem:kmalloc_node in the 11e9734bcb6a7361 ("mm/slab_common: unify NUMA and UMA version of tracepoints") commit, making sure it works with Linux >= 6.2 as well as with older kernels where those tracepoints are present. - Also make it handle the new "node" kmem:kmalloc and kmem:kmem_cache_alloc tracepoint field introduced in that same commit. - Fix hardware tracing PMU address filter duplicate symbol selection, that was preventing to match with static functions with the same name present in different object files. - Fix regression on what linux/types.h file gets used to build the "BPF prologue" 'perf test' entry, the system one lacks the fmode_t definition used in this test, so provide that type in the test itself. - Avoid build breakage with libbpf < 0.8.0 + LIBBPF_DYNAMIC=1. If the user asks for linking with the libbpf package provided by the distro, then it has to be >= 0.8.0. Using the libbpf supplied with the kernel would be a fallback in that case. - Fix the build when libbpf isn't available or explicitly disabled via NO_LIBBPF=1. - Don't try to install libtraceevent plugins as its not anymore in the kernel sources and will thus always fail. * tag 'perf-tools-fixes-for-v6.2-2-2023-01-11' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: perf auxtrace: Fix address filter duplicate symbol selection perf bpf: Avoid build breakage with libbpf < 0.8.0 + LIBBPF_DYNAMIC=1 perf build: Fix build error when NO_LIBBPF=1 perf tools: Don't install libtraceevent plugins as its not anymore in the kernel sources perf kmem: Support field "node" in evsel__process_alloc_event() coping with recent tracepoint restructuring perf kmem: Support legacy tracepoints perf build: Properly guard libbpf includes perf tests bpf prologue: Fix bpf-script-test-prologue test compile issue with clang

2023-01-10perf bpf: Avoid build breakage with libbpf < 0.8.0 + LIBBPF_DYNAMIC=1Arnaldo Carvalho de Melo
In 746bd29e348f99b4 ("perf build: Use tools/lib headers from install path") we stopped having the tools/lib/ directory from the kernel sources in the header include path unconditionally, which breaks the build on systems with older versions of libbpf-devel, in this case 0.7.0 as some of the structures and function declarations present in the newer version of libbpf included in the kernel sources (tools/lib/bpf) are not anymore used, just the ones in the system libbpf. So instead of trying to provide alternative functions when the libbpf-bpf_program__set_insns feature test fails, fail a LIBBPF_DYNAMIC=1 build (requesting the use of the system's libbpf) and emit this build error message: $ make LIBBPF_DYNAMIC=1 -C tools/perf Makefile.config:593: *** Error: libbpf devel library needs to be >= 0.8.0 to build with LIBBPF_DYNAMIC, update or build statically with the version that comes with the kernel sources. Stop. $ For v6.3 these tests will be revamped and we'll require libbpf 1.0 as a minimal version for using LIBBPF_DYNAMIC=1, most distros should have it by now or at v6.3 time.

2023-01-10perf build: Fix build error when NO_LIBBPF=1Ian Rogers
The $(LIBBPF) target should only be a dependency of prepare if the static version of libbpf is needed. Add a new LIBBPF_STATIC variable that is set by Makefile.config. Use LIBBPF_STATIC to determine whether the CFLAGS, etc. need updating and for adding $(LIBBPF) as a prepare dependency. As Makefile.config isn't loaded for "clean" as a target, always set LIBBPF_OUTPUT regardless of whether it is needed for $(LIBBPF). This is done to minimize conditional logic for $(LIBBPF)-clean.

2023-01-10perf kmem: Support field "node" in evsel__process_alloc_event() coping with ↵Leo Yan
recent tracepoint restructuring Commit 11e9734bcb6a7361 ("mm/slab_common: unify NUMA and UMA version of tracepoints") adds the field "node" into the tracepoints 'kmalloc' and 'kmem_cache_alloc', so this patch modifies the event process function to support the field "node". If field "node" is detected by checking function evsel__field(), it stats the cross allocation. When the "node" value is NUMA_NO_NODE (-1), it means the memory can be allocated from any memory node, in this case, we don't account it as a cross allocation.

2023-01-09gcc: disable -Warray-bounds for gcc-11 tooLinus Torvalds
We had already disabled this warning for gcc-12 due to bugs in the value range analysis, but it turns out we end up having some similar problems with gcc-11.3 too, so let's disable it there too. Older gcc versions end up being increasingly less relevant, and hopefully clang and newer version of gcc (ie gcc-13) end up working reliably enough that we still get the build coverage even when we disable this for some versions.

2023-01-09perf tests bpf prologue: Fix bpf-script-test-prologue test compile issue ↵Athira Rajeev
with clang While running 'perf test' for bpf, observed that "BPF prologue generation" test case fails to compile with clang. Logs below from powerpc: <stdin>:33:2: error: use of undeclared identifier 'fmode_t' fmode_t f_mode = (fmode_t)_f_mode; ^ <stdin>:37:6: error: use of undeclared identifier 'f_mode'; did you mean '_f_mode'? if (f_mode & FMODE_WRITE) ^~~~~~ _f_mode <stdin>:30:60: note: '_f_mode' declared here int bpf_func__null_lseek(void *ctx, int err, unsigned long _f_mode, ^ 2 errors generated. The test code tests/bpf-script-test-prologue.c uses fmode_t. And the error above is for "fmode_t" which is defined in include/linux/types.h as part of kernel build directory: "/lib/modules/<kernel_version>/build" that comes from kernel devel [ soft link to /usr/src/<kernel_version> ]. Clang picks this header file from "-working-directory" build option that specifies this build folder. But the commit 14e4b9f4289aed2c ("perf trace: Raw augmented syscalls fix libbpf 1.0+ compatibility") changed the include directory to use: "/usr/include". Post this change, types.h from /usr/include/ is getting picked upwhich doesn’t contain definition of "fmode_t" and hence fails to compile.

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).

2023-01-06nfsd: fix handling of cached open files in nfsd4_open codepathJeff Layton
Commit fb70bf124b05 ("NFSD: Instantiate a struct file when creating a regular NFSv4 file") added the ability to cache an open fd over a compound. There are a couple of problems with the way this currently works: It's racy, as a newly-created nfsd_file can end up with its PENDING bit cleared while the nf is hashed, and the nf_file pointer is still zeroed out. Other tasks can find it in this state and they expect to see a valid nf_file, and can oops if nf_file is NULL. Also, there is no guarantee that we'll end up creating a new nfsd_file if one is already in the hash. If an extant entry is in the hash with a valid nf_file, nfs4_get_vfs_file will clobber its nf_file pointer with the value of op_file and the old nf_file will leak. Fix both issues by making a new nfsd_file_acquirei_opened variant that takes an optional file pointer. If one is present when this is called, we'll take a new reference to it instead of trying to open the file. If the nfsd_file already has a valid nf_file, we'll just ignore the optional file and pass the nfsd_file back as-is. Also rework the tracepoints a bit to allow for an "opened" variant and don't try to avoid counting acquisitions in the case where we already have a cached open file.

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: uaccess: fix type of 0 variable on error in get_user()Ben Dooks
If the get_user(x, ptr) has x as a pointer, then the setting of (x) = 0 is going to produce the following sparse warning, so fix this by forcing the type of 'x' when access_ok() fails. fs/aio.c:2073:21: warning: Using plain integer as NULL pointer Signed-off-by: Ben Dooks <ben-linux@fluff.org> Reviewed-by: Palmer Dabbelt <palmer@rivosinc.com> Link: https://lore.kernel.org/r/20221229170545.718264-1-ben-linux@fluff.org Cc: stable@vger.kernel.org Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
