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").

2020-04-17of: unittest: kmemleak in duplicate property updateFrank Rowand2-10/+25
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. Thus users of kmemleak will not have to debug this leak in the future.

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 <fdmanana@suse.com> Signed-off-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: David Sterba <dsterba@suse.com>

The driver uses __napi_schedule_irqoff() which is fine as long as it is invoked with disabled interrupts by everybody. Since the commit mentioned below the driver may invoke xgbe_isr_task() in tasklet/softirq context. This may lead to list corruption if another driver uses __napi_schedule_irqoff() in IRQ context. Use __napi_schedule() which safe to use from IRQ and softirq context.

2020-04-16net: stmmac: dwmac-sunxi: Provide TX and RX fifo sizesFlorian Fainelli1-0/+2
After commit bfcb813203e619a8960a819bf533ad2a108d8105 ("net: dsa: configure the MTU for switch ports") my Lamobo R1 platform which uses an allwinner,sun7i-a20-gmac compatible Ethernet MAC started to fail by rejecting a MTU of 1536. The reason for that is that the DMA capabilities are not readable on this version of the IP, and there is also no 'tx-fifo-depth' property being provided in Device Tree. The property is documented as optional, and is not provided. Chen-Yu indicated that the FIFO sizes are 4KB for TX and 16KB for RX, so provide these values through platform data as an immediate fix until various Device Tree sources get updated accordingly.

2020-04-16xfs: move inode flush to the sync workqueueDarrick J. Wong2-19/+27
Move the inode dirty data flushing to a workqueue so that multiple threads can take advantage of a single thread's flushing work. The ratelimiting technique used in bdd4ee4 was not successful, because threads that skipped the inode flush scan due to ratelimiting would ENOSPC early, which caused occasional (but noticeable) changes in behavior and sporadic fstest regressions. Therefore, make all the writer threads wait on a single inode flush, which eliminates both the stampeding hordes of flushers and the small window in which a write could fail with ENOSPC because it lost the ratelimit race after even another thread freed space.
