2021-04-10btrfs: zoned: move superblock logging zone locationNaohiro Aota1-11/+42
Moves the location of the superblock logging zones. The new locations of the logging zones are now determined based on fixed block addresses instead of on fixed zone numbers. The old placement method based on fixed zone numbers causes problems when one needs to inspect a file system image without access to the drive zone information. In such case, the super block locations cannot be reliably determined as the zone size is unknown. By locating the superblock logging zones using fixed addresses, we can scan a dumped file system image without the zone information since a super block copy will always be present at or after the fixed known locations. Introduce the following three pairs of zones containing fixed offset locations, regardless of the device zone size. - primary superblock: offset 0B (and the following zone) - first copy: offset 512G (and the following zone) - Second copy: offset 4T (4096G, and the following zone) If a logging zone is outside of the disk capacity, we do not record the superblock copy. The first copy position is much larger than for a non-zoned filesystem, which is at 64M. This is to avoid overlapping with the log zones for the primary superblock. This higher location is arbitrary but allows supporting devices with very large zone sizes, plus some space around in between. Such large zone size is unrealistic and very unlikely to ever be seen in real devices. Currently, SMR disks have a zone size of 256MB, and we are expecting ZNS drives to be in the 1-4GB range, so this limit gives us room to breathe. For now, we only allow zone sizes up to 8GB. The maximum zone size that would still fit in the space is 256G. The fixed location addresses are somewhat arbitrary, with the intent of maintaining superblock reliability for smaller and larger devices, with the preference for the latter. For this reason, there are two superblocks under the first 1T. This should cover use cases for physical devices and for emulated/device-mapper devices. The superblock logging zones are reserved for superblock logging and never used for data or metadata blocks. Note that we only reserve the two zones per primary/copy actually used for superblock logging. We do not reserve the ranges of zones possibly containing superblocks with the largest supported zone size (0-16GB, 512G-528GB, 4096G-4112G). The zones containing the fixed location offsets used to store superblocks on a non-zoned volume are also reserved to avoid confusion.

2021-04-09ia64: fix user_stack_pointer() for ptrace()Sergei Trofimovich1-7/+1
ia64 has two stacks: - memory stack (or stack), pointed at by by r12 - register backing store (register stack), pointed at by ar.bsp/ar.bspstore with complications around dirty register frame on CPU. In [1] Dmitry noticed that PTRACE_GET_SYSCALL_INFO returns the register stack instead memory stack. The bug comes from the fact that user_stack_pointer() and current_user_stack_pointer() don't return the same register: ulong user_stack_pointer(struct pt_regs *regs) { return regs->ar_bspstore; } #define current_user_stack_pointer() (current_pt_regs()->r12) The change gets both back in sync. I think ptrace(PTRACE_GET_SYSCALL_INFO) is the only affected user by this bug on ia64. The change fixes 'rt_sigreturn.gen.test' strace test where it was observed initially.

The same deadlock was mentioned in upstream commit 28f5a8a7c033 ("ocfs2: should wait dio before inode lock in ocfs2_setattr()"). It seems that that commit only removed the cluster lock (the victim of above dead lock) from the ABBA deadlock party. End-user visible effects: Process hang in truncate -> ocfs2_setattr path and other processes hang at ocfs2_dio_end_io_write path. This is to fix the deadlock itself. It removes inode_lock() call from dio completion path to remove the deadlock and add ip_alloc_sem lock in setattr path to synchronize the inode modifications.

When we do coredump for user process signal, this may be an SIGBUS signal with BUS_MCEERR_AR or BUS_MCEERR_AO code, which means this signal is resulted from ECC memory fail like SRAR or SRAO, we expect the memory recovery work is finished correctly, then the get_dump_page() will not return the error page as its process pte is set invalid by memory_failure(). But memory_failure() may fail, and the process's related pte may not be correctly set invalid, for current code, we will return the poison page, get it dumped, and then lead to system panic as its in kernel code. So check the poison status in get_dump_page(), and if TRUE, return NULL. There maybe other scenario that is also better to check the posion status and not to panic, so make a wrapper for this check, Thanks to David's suggestion(<david@redhat.com>).

2021-04-09drm/amd/display: Add MST capability to trigger_hotplug interfaceMikita Lipski1-1/+70
[Why] Need to be able to trigger software hotplug for MST connectors [How] For unplug the driver calls to disable topologies manager that connector is attached to. For plugging in it does the whole rediscovery of all connectors in drm device and enbles their topologies if attached. The interface for MST connectors works in the following way: 1. To disconnect all MST topologies currently connected: echo 0 > /sys/kernel/debug/dri/0/amdgpu_dm_trigger_hpd_mst 2. To reconnect/rediscover all topologies that are physically connected to the card: echo 1 > /sys/kernel/debug/dri/0/amdgpu_dm_trigger_hpd_mst A related fix which has been merged with this patch Leo Ma(Hanghong Ma)'s work: Set power states before disable MST topology [Why] When we try to disable MST topology from the debugfs entry, some receiver will hang.
