But the default value should hopefully be good for any normal load,\nallowing a few rounds of lock stealing, but enforcing the strict\nordering before the lock has been stolen too many times.\n\nThere is also a hint from Matthieu Baerts that the fair page coloring\nmay end up exposing an ABBA deadlock that is hidden by the usual\noptimistic lock stealing, and while the unfairness doesn\u0027t fix the\nfundamental issue (and I\u0027m still looking at that), it avoids it in\npractice.\n\nThe amount of unfairness can be modified by writing a new value to the\n\u0027sysctl_page_lock_unfairness\u0027 variable (default value of 5, exposed\nthrough /proc/sys/vm/page_lock_unfairness), but that is hopefully\nsomething we\u0027d use mainly for debugging rather than being necessary for\nany deep system tuning.\n\nThis whole issue has exposed just how critical the page lock can be, and\nhow contended it gets under certain locks. And the main contention\ndoesn\u0027t really seem to be anything related to IO (which was the origin\nof this lock), but for things like just verifying that the page file\nmapping is stable while faulting in the page into a page table.\n\nLink: https://lore.kernel.org/linux-fsdevel/ed8442fd-6f54-dd84-cd4a-941e8b7ee603@MichaelLarabel.com/\nLink: https://www.phoronix.com/scan.php?page\u003darticle\u0026item\u003dlinux-50-59\u0026num\u003d1\nLink: https://lore.kernel.org/linux-fsdevel/c560a38d-8313-51fb-b1ec-e904bd8836bc@tessares.net/\nReported-and-tested-by: Michael Larabel \u003cMichael@michaellarabel.com\u003e\nTested-by: Matthieu Baerts \u003cmatthieu.baerts@tessares.net\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Matthew Wilcox \u003cwilly@infradead.org\u003e\nCc: Chris Mason \u003cclm@fb.com\u003e\nCc: Jan Kara \u003cjack@suse.cz\u003e\nCc: Amir Goldstein \u003camir73il@gmail.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "75df529bec9110dad43ab30e2d9490242529e8b8", "tree": "d27d37d398bccf17dee37ef7d5b42069f0406bfa", "parents": [ "32f6865c7aa3c422f710903baa6eb81abc6f559b" ], "author": { "name": "Andrew Jones", "email": "drjones@redhat.com", "time": "Wed Sep 16 17:45:30 2020 +0200" }, "committer": { "name": "Catalin Marinas", "email": "catalin.marinas@arm.com", "time": "Thu Sep 17 18:12:18 2020 +0100" }, "message": "arm64: paravirt: Initialize steal time when cpu is online\n\nSteal time initialization requires mapping a memory region which\ninvokes a memory allocation.

The code currently omits the first instruction, since\nbuild_insn() will increase our ctx-\u003eidx before saving it.\nThat was fine up until bounded eBPF loops were introduced. After that\nintroduction, offset[0] must be the offset of the end of prologue which\nis the start of the 1st insn while, offset[n] holds the\noffset of the end of n-th insn.\n\nWhen \"taken loop with back jump to 1st insn\" test runs, it will\neventually call bpf2a64_offset(-1, 2, ctx). Since negative indexing is\npermitted, the current outcome depends on the value stored in\nctx-\u003eoffset[-1], which has nothing to do with our array.\nIf the value happens to be 0 the tests will work. If not this error\ntriggers.\n\ncommit 7c2e988f400e (\"bpf: fix x64 JIT code generation for jmp to 1st insn\")\nfixed an indentical bug on x86 when eBPF bounded loops were introduced.\n\nSo let\u0027s fix it by creating the ctx-\u003eoffset[] differently. Track the\nbeginning of instruction and account for the extra instruction while\ncalculating the arm instruction offsets.\n\nFixes: 2589726d12a1 (\"bpf: introduce bounded loops\")\nReported-by: Naresh Kamboju \u003cnaresh.kamboju@linaro.org\u003e\nReported-by: Jiri Olsa \u003cjolsa@kernel.org\u003e\nCo-developed-by: Jean-Philippe Brucker \u003cjean-philippe@linaro.org\u003e\nCo-developed-by: Yauheni Kaliuta \u003cyauheni.kaliuta@redhat.com\u003e\nSigned-off-by: Jean-Philippe Brucker \u003cjean-philippe@linaro.org\u003e\nSigned-off-by: Yauheni Kaliuta \u003cyauheni.kaliuta@redhat.com\u003e\nSigned-off-by: Ilias Apalodimas \u003cilias.apalodimas@linaro.org\u003e\nAcked-by: Will Deacon \u003cwill@kernel.org\u003e\nLink: https://lore.kernel.org/r/20200917084925.177348-1-ilias.apalodimas@linaro.org\nSigned-off-by: Catalin Marinas \u003ccatalin.marinas@arm.com\u003e\n" }, { "commit": "29231826f3bd65500118c473fccf31c0cf14dbc0", "tree": "cc93fb0849ab08d14af6ea880156210d7c5bd27a", "parents": [ "d69030c91b3765934048151792f141f0571efa86" ], "author": { "name": "Quentin Perret", "email": "qperret@google.com", "time": "Wed Sep 16 18:18:25 2020 +0100" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Sep 17 08:39:50 2020 +0200" }, "message": "ehci-hcd: Move include to keep CRC stable\n\nThe CRC calculation done by genksyms is triggered when the parser hits\nEXPORT_SYMBOL*() macros. At this point, genksyms recursively expands the\ntypes of the function parameters, and uses that as the input for the CRC\ncalculation. In the case of forward-declared structs, the type expands\nto \u0027UNKNOWN\u0027. Following this, it appears that the result of the\nexpansion of each type is cached somewhere, and seems to be re-used\nwhen/if the same type is seen again for another exported symbol in the\nsame C file.\n\nUnfortunately, this can cause CRC \u0027stability\u0027 issues when a struct\ndefinition becomes visible in the middle of a C file. For example, let\u0027s\nassume code with the following pattern:\n\n struct foo;\n\n int bar(struct foo *arg)\n {\n\t/* Do work ... */\n }\n EXPORT_SYMBOL_GPL(bar);\n\n /* This contains struct foo\u0027s definition */\n #include \"foo.h\"\n\n int baz(struct foo *arg)\n {\n\t/* Do more work ... */\n }\n EXPORT_SYMBOL_GPL(baz);\n\nHere, baz\u0027s CRC will be computed using the expansion of struct foo that\nwas cached after bar\u0027s CRC calculation (\u0027UNKOWN\u0027 here). But if\nEXPORT_SYMBOL_GPL(bar) is removed from the file (because of e.g. symbol\ntrimming using CONFIG_TRIM_UNUSED_KSYMS), struct foo will be expanded\nlate, during baz\u0027s CRC calculation, which now has visibility over the\nfull struct definition, hence resulting in a different CRC for baz.\n\nThe proper fix for this certainly is in genksyms, but that will take me\nsome time to get right. In the meantime, we have seen one occurrence of\nthis in the ehci-hcd code which hits this problem because of the way it\nincludes C files halfway through the code together with an unlucky mix\nof symbol trimming.\n\nIn order to workaround this, move the include done in ehci-hub.c early\nin ehci-hcd.c, hence making sure the struct definitions are visible to\nthe entire file. This improves CRC stability of the ehci-hcd exports\neven when symbol trimming is enabled.\n\nAcked-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: stable \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Quentin Perret \u003cqperret@google.com\u003e\nLink: https://lore.kernel.org/r/20200916171825.3228122-1-qperret@google.com\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n" }, { "commit": "875d369d8f75275d30e59421602d9366426abff7", "tree": "73d6c678636405f1be983d76af77fde7af921737", "parents": [ "e60c27f1ffc733e729319662f75419f4d4fb6a80" ], "author": { "name": "Bhawanpreet Lakha", "email": "Bhawanpreet.Lakha@amd.com", "time": "Tue Sep 15 17:26:29 2020 -0400" }, "committer": { "name": "Alex Deucher", "email": "alexander.deucher@amd.com", "time": "Thu Sep 17 00:13:34 2020 -0400" }, "message": "drm/amd/display: Don\u0027t log hdcp module warnings in dmesg\n\n[Why]\nDTM topology updates happens by default now.
