Patch series "Add support for DMA writable pages being writable by the network stack", v3. The first 19 patches in the set add support for the DMA attribute DMA_ATTR_SKIP_CPU_SYNC on multiple platforms/architectures. This is needed so that we can flag the calls to dma_map/unmap_page so that we do not invalidate cache lines that do not currently belong to the device. Instead we have to take care of this in the driver via a call to sync_single_range_for_cpu prior to freeing the Rx page. Patch 20 adds support for dma_map_page_attrs and dma_unmap_page_attrs so that we can unmap and map a page using the DMA_ATTR_SKIP_CPU_SYNC attribute. Patch 21 adds support for freeing a page that has multiple references being held by a single caller. This way we can free page fragments that were allocated by a given driver. The last 2 patches use these updates in the igb driver, and lay the groundwork to allow for us to reimplement the use of build_skb. This patch (of 23): This change allows us to pass DMA_ATTR_SKIP_CPU_SYNC which allows us to avoid invoking cache line invalidation if the driver will just handle it later via a sync_for_cpu or sync_for_device call.

Currently in x86_64, the symbol address of phys_base is exported to vmcoreinfo. Dave Anderson complained this is really useless for his Crash implementation. Because in user-space utility Crash and Makedumpfile which exported vmcore information is mainly used for, value of phys_base is needed to covert virtual address of exported kernel symbol to physical address. Especially init_level4_pgt, if we want to access and go over the page table to look up a PA corresponding to VA, firstly we need calculate page_dir = SYMBOL(init_level4_pgt) - __START_KERNEL_map + phys_base; Now in Crash and Makedumpfile, we have to analyze the vmcore elf program header to get value of phys_base. As Dave said, it would be preferable if it were readily availabl in vmcoreinfo rather than depending upon the PT_LOAD semantics. Hence in this patch change to export the value of phys_base instead of its virtual address. And people also complained that KERNEL_IMAGE_SIZE exporting is x86_64 only, should be moved into arch dependent function arch_crash_save_vmcoreinfo. Do the moving in this patch.

This reverts commit 0549a3c0 ("kdump, vmcoreinfo: report memory sections virtual addresses"). Commit 0549a3c0 tells the userspace utility makedumpfile the randomized base address of these memmory sections when mm kaslr is enabled. However the following patch "kexec: export the value of phys_base instead of symbol address" makes makedumpfile not need these addresses any more. Besides we should use VMCOREINFO_NUMBER to export the value of the variable so that we can use the existing number_table mechanism of Makedumpfile to fetch it. So revert it now. If needed we can add it later. http://lists.infradead.org/pipermail/kexec/2016-October/017540.html Link: http://lkml.kernel.org/r/1478568596-30060-1-git-send-email-bhe@redhat.comSigned-off-by: NBaoquan He <bhe@redhat.com> Cc: Thomas Garnier <thgarnie@google.com> Cc: Baoquan He <bhe@redhat.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H .

I was amused to find "unsafe core_pattern" warning having these lines in /etc/sysctl.conf: fs.suid_dumpable=2 kernel.core_pattern=/core/core-%e-%p-%E kernel.core_uses_pid=0 Turns out kernel is formally right. Default core_pattern is just "core", which doesn't qualify for secure path while setting suid.dumpable. Hint admins about solution, clarify sysctl names, delete unnecessary '\' characters (string literals are concatenated regardless) and reformat for easier grepping.

A check was added to the __set_current_blocked() function to avoid taking the sighand->siglock spinlock if there is no change in the signal mask. This will prevent unneeded spinlock contention when many threads are trying to call sigprocmask(). With this patch applied, the spinlock contention in sigprocmask() was gone.

compaction has been disabled for GFP_NOFS and GFP_NOIO requests since the direct compaction was introduced by commit 56de7263 ("mm: compaction: direct compact when a high-order allocation fails"). The main reason is that the migration of page cache pages might recurse back to fs/io layer and we could potentially deadlock. This is overly conservative because all the anonymous memory is migrateable in the GFP_NOFS context just fine. This might be a large portion of the memory in many/most workkloads. Remove the GFP_NOFS restriction and make sure that we skip all fs pages (those with a mapping) while isolating pages to be migrated. We cannot consider clean fs pages because they might need a metadata update so only isolate pages without any mapping for nofs requests. The effect of this patch will be probably very limited in many/most workloads because higher order GFP_NOFS requests are quite rare, although different configurations might lead to very different results. David Chinner has mentioned a heavy metadata workload with 64kB block which to quote him: : Unfortunately, there was an era of cargo cult configuration tweaks in the : Ceph community that has resulted in a large number of production machines : with XFS filesystems configured this way. And a lot of them store large : numbers of small files and run under significant sustained memory : pressure. : : I slowly working towards getting rid of these high order allocations and : replacing them with the equivalent number of single page allocations, but : I haven't got that (complex) change working yet. We can do the following to simulate that workload: $ mkfs.xfs -f -n size=64k <dev> $ mount <dev> /mnt/scratch $ time ./fs_mark -D 10000 -S0 -n 100000 -s 0 -L 32 \ -d /mnt/scratch/0 -d /mnt/scratch/1 \ -d /mnt/scratch/2 -d /mnt/scratch/3 \ -d /mnt/scratch/4 -d /mnt/scratch/5 \ -d /mnt/scratch/6 -d /mnt/scratch/7 \ -d /mnt/scratch/8 -d /mnt/scratch/9 \ -d /mnt/scratch/10 -d /mnt/scratch/11 \ -d /mnt/scratch/12 -d /mnt/scratch/13 \ -d /mnt/scratch/14 -d /mnt/scratch/15 and indeed is hammers the system with many high order GFP_NOFS requests as per a simle tracepoint during the load: $ echo '!(gfp_flags & 0x80) && (gfp_flags &0x400000)' > $TRACE_MNT/events/kmem/mm_page_alloc/filter I am getting 5287609 order=0 37 order=1 1594905 order=2 3048439 order=3 6699207 order=4 66645 order=5 My testing was done in a kvm guest so performance numbers should be taken with a grain of salt but there seems to be a difference when the patch is applied: * Original kernel FSUse% Count Size Files/sec App Overhead 1 1600000 0 4300.1 20745838 3 3200000 0 4239.9 23849857 5 4800000 0 4243.4 25939543 6 6400000 0 4248.4 19514050 8 8000000 0 4262.1 20796169 9 9600000 0 4257.6 21288675 11 11200000 0 4259.7 19375120 13 12800000 0 4220.7 22734141 14 14400000 0 4238.5 31936458 16 16000000 0 4231.5 23409901 18 17600000 0 4045.3 23577700 19 19200000 0 2783.4 58299526 21 20800000 0 2678.2 40616302 23 22400000 0 2693.5 83973996 and xfs complaining about memory allocation not making progress [ 2304.372647] XFS: fs_mark(3289) possible memory allocation deadlock size 65624 in kmem_alloc (mode:0x2408240) [ 2304.443323] XFS: fs_mark(3285) possible memory allocation deadlock size 65728 in kmem_alloc (mode:0x2408240) [ 4796.772477] XFS: fs_mark(3424) possible memory allocation deadlock size 46936 in kmem_alloc (mode:0x2408240) [ 4796.775329] XFS: fs_mark(3423) possible memory allocation deadlock size 51416 in kmem_alloc (mode:0x2408240) [ 4797.388808] XFS: fs_mark(3424) possible memory allocation deadlock size 65728 in kmem_alloc (mode:0x2408240) * Patched kernel FSUse% Count Size Files/sec App Overhead 1 1600000 0 4289.1 19243934 3 3200000 0 4241.6 32828865 5 4800000 0 4248.7 32884693 6 6400000 0 4314.4 19608921 8 8000000 0 4269.9 24953292 9 9600000 0 4270.7 33235572 11 11200000 0 4346.4 40817101 13 12800000 0 4285.3 29972397 14 14400000 0 4297.2 20539765 16 16000000 0 4219.6 18596767 18 17600000 0 4273.8 49611187 19 19200000 0 4300.4 27944451 21 20800000 0 4270.6 22324585 22 22400000 0 4317.6 22650382 24 24000000 0 4065.2 22297964 So the dropdown at Count 19200000 didn't happen and there was only a single warning about allocation not making progress [ 3063.815003] XFS: fs_mark(3272) possible memory allocation deadlock size 65624 in kmem_alloc (mode:0x2408240) This suggests that the patch has helped even though there is not all that much of anonymous memory as the workload mostly generates fs metadata.

NMI handler doesn't call set_irq_regs(), it's set only by normal IRQ. Thus get_irq_regs() returns NULL or stale registers snapshot with IP/SP pointing to the code interrupted by IRQ which was interrupted by NMI. NULL isn't a problem: in this case watchdog calls dump_stack() and prints full stack trace including NMI. But if we're stuck in IRQ handler then NMI watchlog will print stack trace without IRQ part at all. This patch uses registers snapshot passed into NMI handler as arguments: these registers point exactly to the instruction interrupted by NMI.

This reverts commit 6d31e3ba. This causes bootup problems for me both on my laptop and my desktop. What they have in common is that they have NVMe disks with dm-crypt, but it's not the same controller, so it's not controller-specific. Jens does not see it on his machine (also NVMe), so it's presumably something that triggers just on bootup. Possibly related to dm-crypt and the fact that I mark my luks volume with "allow-discards" in /etc/crypttab. It's 100% repeatable for me, which made it fairly straightforward to bisect the problem to this commit. Small mercies. So we don't know what the reason is yet, but the revert is needed to get things going again.

Previously, when the ata device was being initialized we were probing for NCQ prio support by checking the identify information and also checking the log page that holds information about ncq prio support. This caused an error on an Intel HBA so the code is now updated to only probe for NCQ prio support when the sysfs variable controlling NCQ prio support is enabled. tj: Update formatting, switch to spin_[un]lock_irq() and update locking a bit, use REVALIDATE instead of RESET, and return -EIO instead of -EINVAL on config failure.
