2020-04-17x86/resctrl: Preserve CDP enable over CPU hotplugJames Morse3-0/+16
Resctrl assumes that all CPUs are online when the filesystem is mounted, and that CPUs remember their CDP-enabled state over CPU hotplug. This goes wrong when resctrl's CDP-enabled state changes while all the CPUs in a domain are offline. When a domain comes online, enable (or disable!) CDP to match resctrl's current setting.

2020-04-17kbuild: check libyaml installation for 'make dt_binding_check'Masahiro Yamada1-1/+1
If you run 'make dtbs_check' without installing the libyaml package, the error message "dtc needs libyaml ..." is shown. This should be checked also for 'make dt_binding_check' because dtc needs to validate *.example.dts extracted from *.yaml files. It is missing since commit 4f0e3a57d6eb ("kbuild: Add support for DT binding schema checks"), but this fix-up is applicable only after commit e10c4321dc1e ("kbuild: allow to run dt_binding_check and dtbs_check in a single command").

2020-04-17x86/resctrl: Fix invalid attempt at removing the default resource groupReinette Chatre1-1/+2
The default resource group ("rdtgroup_default") is associated with the root of the resctrl filesystem and should never be removed. New resource groups can be created as subdirectories of the resctrl filesystem and they can be removed from user space. There exists a safeguard in the directory removal code (rdtgroup_rmdir()) that ensures that only subdirectories can be removed by testing that the directory to be removed has to be a child of the root directory. A possible deadlock was recently fixed with 334b0f4e9b1b ("x86/resctrl: Fix a deadlock due to inaccurate reference"). This fix involved associating the private data of the "mon_groups" and "mon_data" directories to the resource group to which they belong instead of NULL as before. A consequence of this change was that the original safeguard code preventing removal of "mon_groups" and "mon_data" found in the root directory failed resulting in attempts to remove the default resource group that ends in a BUG: kernel BUG at mm/slub.c:3969! invalid opcode: 0000 [#1] SMP PTI Call Trace: rdtgroup_rmdir+0x16b/0x2c0 kernfs_iop_rmdir+0x5c/0x90 vfs_rmdir+0x7a/0x160 do_rmdir+0x17d/0x1e0 do_syscall_64+0x55/0x1d0 entry_SYSCALL_64_after_hwframe+0x44/0xa9 Fix this by improving the directory removal safeguard to ensure that subdirectories of the resctrl root directory can only be removed if they are a child of the resctrl filesystem's root _and_ not associated with the default resource group.

kmemleak reports several memory leaks from devicetree unittest. This is the fix for problem 5 of 5. When overlay 'overlay_bad_add_dup_prop' is applied, the apply code properly detects that a memory leak will occur if the overlay is removed since the duplicate property is located in a base devicetree node and reports via printk(): OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail The overlay is removed when the apply code detects multiple changesets modifying the same property. This is reported via printk(): OF: overlay: ERROR: multiple fragments add, update, and/or delete property /testcase-data-2/substation@100/motor-1/rpm_avail As a result of this error, the overlay is removed resulting in the expected memory leak. Add another device node level to the overlay so that the duplicate property is located in a node added by the overlay, thus no memory leak will occur when the overlay is removed.

kmemleak reports several memory leaks from devicetree unittest. This is the fix for problem 2 of 5. of_unittest_platform_populate() left an elevated reference count for grandchild nodes (which are platform devices). Fix the platform device reference counts so that the memory will be freed.

kmemleak reports several memory leaks from devicetree unittest. This is the fix for problem 1 of 5. of_unittest_changeset() reaches deeply into the dynamic devicetree functions. Several nodes were left with an elevated reference count and thus were not properly cleaned up. Fix the reference counts so that the memory will be freed.

2020-04-17btrfs: fix setting last_trans for reloc rootsJosef Bacik1-2/+17
I made a mistake with my previous fix, I assumed that we didn't need to mess with the reloc roots once we were out of the part of relocation where we are actually moving the extents. The subtle thing that I missed is that btrfs_init_reloc_root() also updates the last_trans for the reloc root when we do btrfs_record_root_in_trans() for the corresponding fs_root. I've added a comment to make sure future me doesn't make this mistake again. This showed up as a WARN_ON() in btrfs_copy_root() because our last_trans didn't == the current transid. This could happen if we snapshotted a fs root with a reloc root after we set rc->create_reloc_tree = 0, but before we actually merge the reloc root. Worth mentioning that the regression produced the following warning when running snapshot creation and balance in parallel: BTRFS info (device sdc): relocating block group 30408704 flags metadata|dup ------------[ cut here ]------------ WARNING: CPU: 0 PID: 12823 at fs/btrfs/ctree.c:191 btrfs_copy_root+0x26f/0x430 [btrfs] CPU: 0 PID: 12823 Comm: btrfs Tainted: G W 5.6.0-rc7-btrfs-next-58 #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.12.0-59-gc9ba5276e321-prebuilt.qemu.org 04/01/2014 RIP: 0010:btrfs_copy_root+0x26f/0x430 [btrfs] RSP: 0018:ffffb96e044279b8 EFLAGS: 00010202 RAX: 0000000000000009 RBX: ffff9da70bf61000 RCX: ffffb96e04427a48 RDX: ffff9da733a770c8 RSI: ffff9da70bf61000 RDI: ffff9da694163818 RBP: ffff9da733a770c8 R08: fffffffffffffff8 R09: 0000000000000002 R10: ffffb96e044279a0 R11: 0000000000000000 R12: ffff9da694163818 R13: fffffffffffffff8 R14: ffff9da6d2512000 R15: ffff9da714cdac00 FS: 00007fdeacf328c0(0000) GS:ffff9da735e00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000055a2a5b8a118 CR3: 00000001eed78002 CR4: 00000000003606f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: ? create_reloc_root+0x49/0x2b0 [btrfs] ? kmem_cache_alloc_trace+0xe5/0x200 create_reloc_root+0x8b/0x2b0 [btrfs] btrfs_reloc_post_snapshot+0x96/0x5b0 [btrfs] create_pending_snapshot+0x610/0x1010 [btrfs] create_pending_snapshots+0xa8/0xd0 [btrfs] btrfs_commit_transaction+0x4c7/0xc50 [btrfs] ? btrfs_mksubvol+0x3cd/0x560 [btrfs] btrfs_mksubvol+0x455/0x560 [btrfs] __btrfs_ioctl_snap_create+0x15f/0x190 [btrfs] btrfs_ioctl_snap_create_v2+0xa4/0xf0 [btrfs] ? mem_cgroup_commit_charge+0x6e/0x540 btrfs_ioctl+0x12d8/0x3760 [btrfs] ? do_raw_spin_unlock+0x49/0xc0 ? _raw_spin_unlock+0x29/0x40 ? __handle_mm_fault+0x11b3/0x14b0 ? ksys_ioctl+0x92/0xb0 ksys_ioctl+0x92/0xb0 ? trace_hardirqs_off_thunk+0x1a/0x1c __x64_sys_ioctl+0x16/0x20 do_syscall_64+0x5c/0x280 entry_SYSCALL_64_after_hwframe+0x49/0xbe RIP: 0033:0x7fdeabd3bdd7 Fixes: 2abc726ab4b8 ("btrfs: do not init a reloc root if we aren't relocating") Reviewed-by: Filipe Manana <[email protected]> Signed-off-by: Josef Bacik <[email protected]> Signed-off-by: David Sterba <[email protected]>
