This is broken because callers expect 0 to\nmean that the module was successfully loaded.\n\nApparently this was never noticed because this method of disabling\nmodule autoloading isn\u0027t used much, and also most callers don\u0027t use the\nreturn value of request_module() since it\u0027s always necessary to check\nwhether the module registered its functionality or not anyway.\n\nBut improperly returning 0 can indeed confuse a few callers, for example\nget_fs_type() in fs/filesystems.c where it causes a WARNING to be hit:\n\n\tif (!fs \u0026\u0026 (request_module(\"fs-%.*s\", len, name) \u003d\u003d 0)) {\n\t\tfs \u003d __get_fs_type(name, len);\n\t\tWARN_ONCE(!fs, \"request_module fs-%.*s succeeded, but still no fs?\\n\", len, name);\n\t}\n\nThis is easily reproduced with:\n\n\techo \u003e /proc/sys/kernel/modprobe\n\tmount -t NONEXISTENT none /\n\nIt causes:\n\n\trequest_module fs-NONEXISTENT succeeded, but still no fs?\n\tWARNING: CPU: 1 PID: 1106 at fs/filesystems.c:275 get_fs_type+0xd6/0xf0\n\t[...]\n\nThis should actually use pr_warn_once() rather than WARN_ONCE(), since\nit\u0027s also user-reachable if userspace immediately unloads the module.\nRegardless, request_module() should correctly return an error when it\nfails. So let\u0027s make it return -ENOENT, which matches the error when\nthe modprobe binary doesn\u0027t exist.\n\nI\u0027ve also sent patches to document and test this case.\n\nSigned-off-by: Eric Biggers \u003cebiggers@google.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nReviewed-by: Kees Cook \u003ckeescook@chromium.org\u003e\nReviewed-by: Jessica Yu \u003cjeyu@kernel.org\u003e\nAcked-by: Luis Chamberlain \u003cmcgrof@kernel.org\u003e\nCc: Alexei Starovoitov \u003cast@kernel.org\u003e\nCc: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\nCc: Jeff Vander Stoep \u003cjeffv@google.com\u003e\nCc: Ben Hutchings \u003cbenh@debian.org\u003e\nCc: Josh Triplett \u003cjosh@joshtriplett.org\u003e\nCc: \u003cstable@vger.kernel.org\u003e\nLink: http://lkml.kernel.org/r/20200310223731.126894-1-ebiggers@kernel.org\nLink: http://lkml.kernel.org/r/20200312202552.241885-1-ebiggers@kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a50d8d98a87f33efa07adfa20747e13a93839a4b", "tree": "578950351241f47660415616fe1005f7a7950ae0", "parents": [ "bfeb022f8fe4c5afdcfd7a3d868fac9765f9bcad" ], "author": { "name": "Logan Gunthorpe", "email": "logang@deltatee.com", "time": "Fri Apr 10 14:33:39 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 10 15:36:21 2020 -0700" }, "message": "mm/memremap: set caching mode for PCI P2PDMA memory to WC\n\nPCI BAR IO memory should never be mapped as WB, however prior to this\nthe PAT bits were set WB and it was typically overridden by MTRR\nregisters set by the firmware.\n\nSet PCI P2PDMA memory to be UC as this is what it currently, typically,\nends up being mapped as on x86 after the MTRR registers override the\ncache setting.\n\nFuture use-cases may need to generalize this by adding flags to select\nthe caching type, as some P2PDMA cases may not want UC.

However, the P2PDMA code is\ncreating pages for PCI BAR memory which should never be accessed through\nthe cache and instead use either WC or UC. This still works in most\ncases, on x86, because the MTRR registers typically override the caching\nsettings in the page tables for all of the IO memory to be UC-.\nHowever, this tends not to work so well on other arches or some rare x86\nmachines that have firmware which does not setup the MTRR registers in\nthis way.\n\nInstead of this, this series proposes a change to arch_add_memory() to\ntake the pgprot required by the mapping which allows us to explicitly\nset pagetable entries for P2PDMA memory to UC.\n\nThis changes is pretty routine for most of the arches: x86_64, arm64 and\npowerpc simply need to thread the pgprot through to where the page\ntables are setup. x86_32 unfortunately sets up the page tables at boot\nso must use _set_memory_prot() to change their caching mode. ia64, s390\nand sh don\u0027t appear to have an easy way to change the page tables so,\nfor now at least, we just return -EINVAL on such mappings and thus they\nwill not support P2PDMA memory until the work for this is done.

After some time the memory gets\nfragmented by non-movable pages, so the chances to find a contiguous 1GB\nblock are getting close to zero. Even dropping caches manually doesn\u0027t\nhelp a lot.\n\nAt large scale rebooting servers in order to allocate gigantic hugepages\nis quite expensive and complex. At the same time keeping some constant\npercentage of memory in reserved hugepages even if the workload isn\u0027t\nusing it is a big waste: not all workloads can benefit from using 1 GB\npages.\n\nThe following solution can solve the problem:\n1) On boot time a dedicated cma area* is reserved. The size is passed\n as a kernel argument.\n2) Run-time allocations of gigantic hugepages are performed using the\n cma allocator and the dedicated cma area\n\nIn this case gigantic hugepages can be allocated successfully with a\nhigh probability, however the memory isn\u0027t completely wasted if nobody\nis using 1GB hugepages: it can be used for pagecache, anon memory, THPs,\netc.\n\n* On a multi-node machine a per-node cma area is allocated on each node.\n Following gigantic hugetlb allocation are using the first available\n numa node if the mask isn\u0027t specified by a user.\n\nUsage:\n1) configure the kernel to allocate a cma area for hugetlb allocations:\n pass hugetlb_cma\u003d10G as a kernel argument\n\n2) allocate hugetlb pages as usual, e.g.\n echo 10 \u003e /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages\n\nIf the option isn\u0027t enabled or the allocation of the cma area failed,\nthe current behavior of the system is preserved.\n\nx86 and arm-64 are covered by this patch, other architectures can be\ntrivially added later.\n\nThe patch contains clean-ups and fixes proposed and implemented by Aslan\nBakirov and Randy Dunlap.

instead trigger\n its backoff mechanism to give the lock holder a chance to finish\n up.\n\n - Ratelimit writeback flushing when buffered writes encounter ENOSPC.\n\n - Other minor cleanups.\n\n - Make reflink a synchronous operation when the fs is mounted with\n wsync or sync, which means that now we force the log to disk to\n record the changes\"\n\n* tag \u0027xfs-5.7-merge-12\u0027 of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (26 commits)\n xfs: reflink should force the log out if mounted with wsync\n xfs: factor out a new xfs_log_force_inode helper\n xfs: fix inode number overflow in ifree cluster helper\n xfs: remove redundant variable assignment in xfs_symlink()\n xfs: ratelimit inode flush on buffered write ENOSPC\n xfs: return locked status of inode buffer on xfsaild push\n xfs: trylock underlying buffer on dquot flush\n xfs: remove unnecessary ternary from xfs_create\n xfs: don\u0027t write a corrupt unmount record to force summary counter recalc\n xfs: factor inode lookup from xfs_ifree_cluster\n xfs: tail updates only need to occur when LSN changes\n xfs: factor common AIL item deletion code\n xfs: correctly acount for reclaimable slabs\n xfs: Improve metadata buffer reclaim accountability\n xfs: don\u0027t allow log IO to be throttled\n xfs: Throttle commits on delayed background CIL push\n xfs: Lower CIL flush limit for large logs\n xfs: remove some stale comments from the log code\n xfs: refactor unmount record writing\n xfs: merge xlog_commit_record with xlog_write_done\n ...\n" }, { "commit": "d3e5e977abe2b6c98455e4f6acd3b09cb4a0a940", "tree": "10b98674d3196308e625c97ae20baf9d28e6875e", "parents": [ "bbec2a2dc338a19185549c318356e25c65552d15", "0214da7cce2030f1a71fb555e2967faf3b92aebf" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 10 09:52:15 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 10 09:52:15 2020 -0700" }, "message": "Merge tag \u0027acpi-5.7-rc1-3\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm\n\nPull more ACPI updates from Rafael Wysocki:\n \"These prevent a false-positive static checker warning from triggering\n in the ACPI EC driver (Rafael Wysocki), fix white space in an ACPI\n document (Vilhelm Prytz) and add static annotation to one variable\n (Jason Yan)\"\n\n* tag \u0027acpi-5.7-rc1-3\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:\n ACPI, x86/boot: make acpi_nobgrt static\n Documentation: firmware-guide: ACPI: fix table alignment in namespace.rst\n ACPI: EC: Fix up fast path check in acpi_ec_add()\n" }, { "commit": "bbec2a2dc338a19185549c318356e25c65552d15", "tree": "474a9cfab197b0359af9563cc50f81af0b030715", "parents": [ "523a05fc681d139ca98a083fa6685ef22c600326", "a31434bcd4cb73b13cd8136c3cbba966dd01f058" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 10 09:50:00 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 10 09:50:00 2020 -0700" }, "message": "Merge tag \u0027pm-5.7-rc1-3\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm\n\nPull more power management updates from Rafael Wysocki:\n \"Rework compat ioctl handling in the user space hibernation interface\n (Christoph Hellwig) and fix a typo in a function name in the cpuidle\n haltpoll driver (Yihao Wu)\"\n\n* tag \u0027pm-5.7-rc1-3\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:\n cpuidle-haltpoll: Fix small typo\n PM / sleep: handle the compat case in snapshot_set_swap_area()\n PM / sleep: move SNAPSHOT_SET_SWAP_AREA handling into a helper\n" }, { "commit": "523a05fc681d139ca98a083fa6685ef22c600326", "tree": "e82a7d5a63578b1fbe5b830e9a52ae226386f0b6", "parents": [ "c0cc271173b2e1c2d8d0ceaef14e4dfa79eefc0d", "2bc55eaeb88d30accfc1b6ac2708d4e4b81ca260" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 10 09:47:26 2020 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Apr 10 09:47:26 2020 -0700" }, "message": "Merge tag \u0027s390-5.7-2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux\n\nPull more s390 updates from Vasily Gorbik:\n \"Second round of s390 fixes and features for 5.7:\n\n - The rest of fallthrough;

That should be safe and I think the code will eventually\ndo that. It was rightly pointed out by Christian that sharing the\nwait_pidfd.lock was a premature optimization.\n\nIt is also true that my pre-merge window testing was insufficient. So\nremove the premature optimization and give struct pid a dedicated lock of\nit\u0027s own for struct pid things. I have verified that lockdep sees all 3\npaths where we take the new pid-\u003elock and lockdep does not complain.\n\nIt is my current day dream that one day pid-\u003elock can be used to guard the\ntask lists as well and then the tasklist_lock won\u0027t need to be held to\ndeliver signals.
