macfuse macfuse-5.3.1

General

• Add initial support for macOS 27

• Add initial support for Xcode 27

FSModule (FSKit Backend)

• Use the node identifier and generation as the authoritative handle for file system items instead of the inode number. Perform FUSE_LOOKUP to get authoritative handle of directory entries returned by FUSE_READDIR

  Previous releases assumed that the node identifier and inode number were identical, as is the case when using the high level libfuse API without use_ino. This change removes that shortcut and resolves macfuse/macfuse#1166 and macfuse/macfuse#1167.

• Improve stability by fixing a bug in open file handle management

• Improve performance when preparing messages sent to the file system server

• Improve performance when enumerating directories by using FUSE_BATCH_FORGET

Kernel Extension (Kernel Backend)

• Update the kernel extension version to 5.3.1

• Remove the file system item from the name cache when handling FUSE_NOTIFY_INVAL_ENTRY

  This ensures that the next lookup triggers a FUSE_LOOKUP request and resolves macfuse/macfuse#1160.

• Address an incompatibility with the macOS 27 SDK included in Xcode 27.0 beta 1

MFMount.framework

• Turn MFChannelCreateWithDeviceFileDescriptor() into a weak import

  This function will be removed once MFMount() supports mounting volumes using the kernel backend. Check that the symbol is available before calling it.

• Please note that parts of the MFMount.framework API may still change in future releases.

libfuse

• Fix a path deadlock in the high level API when using VNOP_MONITOR. This adds the missing free_path() call in fuse_lib_monitor() and resolves macfuse/macfuse#1168.

libfuse3

• Fix a path deadlock in the high level API when using VNOP_MONITOR. This adds the missing free_path() call in fuse_lib_monitor() and resolves macfuse/macfuse#1168.
