55267c8 Tom Zanussi 18 April 2019, 15:18:50 UTC tracing: Prevent hist_field_var_ref() from accessing NULL tracing_map_elts hist_field_var_ref() is an implementation of hist_field_fn_t(), which can be called with a null tracing_map_elt elt param when assembling a key in event_hist_trigger(). In the case of hist_field_var_ref() this doesn't make sense, because a variable can only be resolved by looking it up using an already assembled key i.e. a variable can't be used to assemble a key since the key is required in order to access the variable. Upper layers should prevent the user from constructing a key using a variable in the first place, but in case one slips through, it shouldn't cause a NULL pointer dereference. Also if one does slip through, we want to know about it, so emit a one-time warning in that case.

fe48319 Kees Cook 20 May 2019, 22:37:49 UTC selftests/timers: Add missing fflush(stdout) calls When running under a pipe, some timer tests would not report output in real-time because stdout flushes were missing after printf()s that lacked a newline.

e810886 Kees Cook 20 May 2019, 22:37:48 UTC selftests: Remove forced unbuffering for test running As it turns out, the "stdbuf" command will actually force all subprocesses into unbuffered output, and some implementations of "echo" turn into single-character writes, which utterly wrecks writes to /sys and /proc files. Instead, drop the "stdbuf" usage, and for any tests that want explicit flushing between newlines, they'll have to add "fflush(stdout);" as needed.

a20d452 Tong Bo 19 April 2019, 07:10:55 UTC selftests/x86: Support Atom for syscall_arg_fault test Atom-based CPUs trigger stack fault when invoke 32-bit SYSENTER instruction with invalid register values. So we also need SIGBUS handling in this case. Following is assembly when the fault exception happens. (gdb) disassemble $eip Dump of assembler code for function __kernel_vsyscall: 0xf7fd8fe0 <+0>: push %ecx 0xf7fd8fe1 <+1>: push %edx 0xf7fd8fe2 <+2>: push %ebp 0xf7fd8fe3 <+3>: mov %esp,%ebp 0xf7fd8fe5 <+5>: sysenter 0xf7fd8fe7 <+7>: int $0x80 => 0xf7fd8fe9 <+9>: pop %ebp 0xf7fd8fea <+10>: pop %edx 0xf7fd8feb <+11>: pop %ecx 0xf7fd8fec <+12>: ret End of assembler dump. According to Intel SDM, this could also be a Stack Segment Fault(#SS, 12), except a normal Page Fault(#PF, 14). Especially, in section 6.9 of Vol.3A, both stack and page faults are within the 10th(lowest priority) class, and as it said, "exceptions within each class are implementation-dependent and may vary from processor to processor". It's expected for processors like Intel Atom to trigger stack fault(SIGBUS), while we get page fault(SIGSEGV) from common Core processors.

52f476a Dan Williams 17 May 2019, 00:05:21 UTC libnvdimm/pmem: Bypass CONFIG_HARDENED_USERCOPY overhead Jeff discovered that performance improves from ~375K iops to ~519K iops on a simple psync-write fio workload when moving the location of 'struct page' from the default PMEM location to DRAM. This result is surprising because the expectation is that 'struct page' for dax is only needed for third party references to dax mappings. For example, a dax-mapped buffer passed to another system call for direct-I/O requires 'struct page' for sending the request down the driver stack and pinning the page. There is no usage of 'struct page' for first party access to a file via read(2)/write(2) and friends. However, this "no page needed" expectation is violated by CONFIG_HARDENED_USERCOPY and the check_copy_size() performed in copy_from_iter_full_nocache() and copy_to_iter_mcsafe(). The check_heap_object() helper routine assumes the buffer is backed by a slab allocator (DRAM) page and applies some checks. Those checks are invalid, dax pages do not originate from the slab, and redundant, dax_iomap_actor() has already validated that the I/O is within bounds. Specifically that routine validates that the logical file offset is within bounds of the file, then it does a sector-to-pfn translation which validates that the physical mapping is within bounds of the block device. Bypass additional hardened usercopy overhead and call the 'no check' versions of the copy_{to,from}_iter operations directly.

Ever since commit 3a06c7ac24f9 ("posix-clocks: Remove interval timer facility and mmap/fasync callbacks") the possibility of PHC based posix timers has been removed. In addition it will probably never make sense to implement this functionality. This patch removes the misleading example code which seems to suggest that posix timers for PHC devices will ever be a thing.

Stephen reported a false positive for ppc64_defconfig: warning: same basename if the following are built as modules: arch/powerpc/platforms/powermac/nvram.ko drivers/char/nvram.ko The former is never built as a module as you see in arch/powerpc/platforms/powermac/Makefile: # CONFIG_NVRAM is an arch. independent tristate symbol, for pmac32 we really # need this to be a bool. Cheat here and pretend CONFIG_NVRAM=m is really # CONFIG_NVRAM=y obj-$(CONFIG_NVRAM:m=y) += nvram.o Another example of false positive is arm64 defconfig: warning: same basename if the following are built as modules: arch/arm64/lib/crc32.ko lib/crc32.ko It is true CONFIG_CRC32 is a tristate option but it is always 'y' since it is select'ed by ARM64. Hence, neither of them is built as a module for the arm64 build. From the above, modules.builtin essentially contains false positives. I do not think it is a big deal as far as kmod is concerned, but false positive warnings in the kernel build make people upset. It is better to not check it. Even without builtin.modules checked, we have enough (and more solid) test coverage with allmodconfig. While I touched this part, I replaced the sed code with neater one provided by Stephen.

7bf7eac Dan Williams 16 May 2019, 20:26:29 UTC dax: Arrange for dax_supported check to span multiple devices Pankaj reports that starting with commit ad428cdb525a "dax: Check the end of the block-device capacity with dax_direct_access()" device-mapper no longer allows dax operation. This results from the stricter checks in __bdev_dax_supported() that validate that the start and end of a block-device map to the same 'pagemap' instance. Teach the dax-core and device-mapper to validate the 'pagemap' on a per-target basis. This is accomplished by refactoring the bdev_dax_supported() internals into generic_fsdax_supported() which takes a sector range to validate. Consequently generic_fsdax_supported() is suitable to be used in a device-mapper ->iterate_devices() callback. A new ->dax_supported() operation is added to allow composite devices to split and route upper-level bdev_dax_supported() requests. Fixes: ad428cdb525a ("dax: Check the end of the block-device...")

a491cc8 Chris Wilson 15 May 2019, 13:00:49 UTC drm/i915: Truly bump ready tasks ahead of busywaits In commit b7404c7ecb38 ("drm/i915: Bump ready tasks ahead of busywaits"), I tried cutting a corner in order to not install a signal for each of our dependencies, and only listened to requests on which we were intending to busywait. The compromise that was made was that instead of then being able to promote the request with a full NOSEMAPHORE like its non-busywaiting brethren, as we had not ensured we had cleared the semaphore chain, we settled for only using the NEWCLIENT boost. With an over saturated system with multiple NEWCLIENTS in flight at any time, this was found to be an inadequate promotion and left us with a much poorer scheduling order than prior to using semaphores. The outcome of this patch, is that all requests have NOSEMAPHORE priority when they have no dependencies and are ready to run and not busywait, restoring the pre-semaphore ordering on saturated systems. We can demonstrate the effect of poor scheduling order by oversaturating the system using gem_wsim on a system with multiple vcs engines (i.e running the same workloads across more clients than required for peak throughput, e.g. media_load_balance_17i7.wsim -c4 -b context): x v5.1 (normalized) + tip * fix +------------------------------------------------------------------------+ | x | | x | | x | | x | | %x | | %%x | | %%x | | %%x | | %%x | | %%x | | %%x | | %%x | | %%x | | %%x | | %%x | | %#x | | %#x | | %#x | | %#x | | %#x | | + %#xx | | + %#xx | | + %%#xx | | + %%#xx | | + %%#xx | | + %%#xx | | + %%##x | | +++ %%##x | | +++ %%##x | | +++ %%##x | | ++++ %%##x | | ++++ %%##x | | ++++ %%##xx | | ++++ %###xx | | ++++ %###xx | | ++++ %###xx | | ++++ %###xx | | ++++ + %#O#xx | | ++++ + %#O#xx | | ++++++ + %#O#xx | | ++++++++++ %OOOxxx| | ++++++++++ + %#OOO#xx| | + ++++++++++++ ++ +++++ + ++ @@OOOO#xx| | |A_| | ||__________M_______A____________________| | | |A_| | +------------------------------------------------------------------------+ N Min Max Median Avg Stddev x 120 0.99456 1.00628 0.999985 1.0001545 0.0024387139 + 120 0.873021 1.00037 0.884134 0.90148752 0.039190862 Difference at 99.5% confidence -0.098667 +/- 0.0110762 -9.86517% +/- 1.10745% (Student's t, pooled s = 0.0277657) % 120 0.990207 1.00165 0.9970265 0.99699748 0.0021024 Difference at 99.5% confidence -0.003157 +/- 0.000908245 -0.315651% +/- 0.0908105% (Student's t, pooled s = 0.00227678) Fixes: b7404c7ecb38 ("drm/i915: Bump ready tasks ahead of busywaits") Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Dmitry Rogozhkin <dmitry.v.rogozhkin@intel.com> Cc: Dmitry Ermilov <dmitry.ermilov@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190515130052.4475-2-chris@chris-wilson.co.uk (cherry picked from commit 17db337f5098d29415314c4a588b842fc684394b) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> 20 May 2019, 15:29:20 UTC
c80274b Chris Wilson 15 May 2019, 13:00:51 UTC drm/i915: Downgrade NEWCLIENT to non-preemptive Commit 1413b2bc0717 ("drm/i915: Trim NEWCLIENT boosting") had the intended consequence of not allowing a sequence of work that merely crossed into a new engine the privilege to be promoted to NEWCLIENT status. It also had the unintended consequence of actually making NEWCLIENT effective on heavily oversubscribed transcode machines and impacting upon their throughput. If we consider a client packet composed of (rcsA, rcsB, vcs) and 30 of those clients, using the NEWCLIENT boost that will be scheduled as rcsA x 30, (rcsB, vcs) x 30 where as before it would have been (rcsA, rcsB, vcs) x 30 That is with NEWCLIENT only boosting the first request of each client, we would execute all rcsA requests prior to running on the vcs engines; acruing a lot of dead time as compared to the previous case where the vcs engine would be started in parallel to processing the second client. The previous patch has the effect of delaying submission until it is required by a third party (either the user with an explicit wait, or by another client/engine). We reduce the NEWCLIENT bump to a mere WAIT, which has the effect of removing its preemptive grant and reducing it to the same level as any other user interaction -- that it will not be promoted above the interengine dependencies, and so preventing NEWCLIENTS from starving other engines. This a large nerf to the rrul properties of the current NEWCLIENT, but it still does give prioritised submission to new requests from light workloads.

9981927 Chris Wilson 15 May 2019, 13:00:50 UTC drm/i915: Bump signaler priority on adding a waiter The handling of the no-preemption priority level imposes the restriction that we need to maintain the implied ordering even though preemption is disabled. Otherwise we may end up with an AB-BA deadlock across multiple engine due to a real preemption event reordering the no-preemption WAITs. To resolve this issue we currently promote all requests to WAIT on unsubmission, however this interferes with the timeslicing requirement that we do not apply any implicit promotion that will defeat the round-robin timeslice list. (If we automatically promote the active request it will go back to the head of the queue and not the tail!) So we need implicit promotion to prevent reordering around semaphores where we are not allowed to preempt, and we must avoid implicit promotion on unsubmission. So instead of at unsubmit, if we apply that implicit promotion on adding the dependency, we avoid the semaphore deadlock and we also reduce the gains made by the promotion for user space waiting. Furthermore, by keeping the earlier dependencies at a higher level, we reduce the search space for timeslicing without altering runtime scheduling too badly (no dependencies at all will be assigned a higher priority for rrul). v2: Limit the bump to external edges (as originally intended) i.e. between contexts and out to the user.

This patch introduced regressions for devices that come online in read-only state and subsequently switch to read-write. Given how the partition code is currently implemented it is not possible to persist the read-only flag across a device revalidate call. This may need to get addressed in the future since it is common for user applications to proactively call BLKRRPART. Reverting this commit will re-introduce a regression where a device-initiated revalidate event will cause the admin state to be forgotten. A separate patch will address this issue.
