- Create a generic copy_file_range handler and make individual filesystems responsible for calling it (i.e. no more assuming that do_splice_direct will work or is appropriate) - Refactor copy_file_range and remap_range parameter checking where they are the same - Install missing copy_file_range parameter checking(!) - Remove suid/sgid and update mtime like any other file write - Change the behavior so that a copy range crossing the source file's eof will result in a short copy to the source file's eof instead of EINVAL - Permit filesystems to decide if they want to handle cross-superblock copy_file_range in their local handlers. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEUzaAxoMeQq6m2jMV+H93GTRKtOsFAl0BGvAACgkQ+H93GTRK tOu2aw/+KGG7PiXm9ED3ZXUppKVddrZMOgqM7mSfHo6TBgW3pJUJcRIhawK0Wz/P stgTsOkurHSl3iT3vQyX4GTZvLoGN/rfsRLPxogJptBUqVv3BOrXsrI53f7V/kbm rtjlYsgExji7VBUiMTe5kOWWqxyR7B4nXyvY/8rier57rW/8C1I58B0OrxAmTK0k rz1e5BtE1dg91xA7cSdEc38FInz8MW8cvsrEzW9vyYY4IVE0PBuhhA1EvryxTrAZ hfthHFfzwxhJkI0mdha8uqNufNWrHLSqiwyjYC7pwAwSQzQPiQz9U17flu+URnfF kXaR5LdXbBP3pl46RdthrfuonWsv612cC1Qwfjs8PBG9lG7b9PGJ40MGVTiw7LlQ 924/03ho0zAnV0E8Qn5O9nPshQNDJhwhzMS39EmMyFKb1D5XGzdMV0gDdIfx6hdO HDbw6VQ33S59gvk7v/gxsFB5Bs4PKfamHx/QmwQwpqWM5XExcr0yJ90OTBtAuY4r S+9gwG6uED3aPh8HbQ5UgnA8bZmMmi8AkcBvqJ9GgNw5SbZl0oyv9Sj6JNpoOejV 8y9JkhoZUxqiihnKTw/vtMrj5RCOfifNBjMSwrShfLdLKtK0AZl1mXC0/1Q3VnEQ TUcyRHEzrtHgJ9/AK9xIyDNvNYzvHSLZj7maoZZumgQa2FOFrmw= =qM44 -----END PGP SIGNATURE----- Merge tag 'copy-file-range-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux Pull copy_file_range updates from Darrick Wong: "This fixes numerous parameter checking problems and inconsistent behaviors in the new(ish) copy_file_range system call. Now the system call will actually check its range parameters correctly; refuse to copy into files for which the caller does not have sufficient privileges; update mtime and strip setuid like file writes are supposed to do; and allows copying up to the EOF of the source file instead of failing the call like we used to. Summary: - Create a generic copy_file_range handler and make individual filesystems responsible for calling it (i.e. no more assuming that do_splice_direct will work or is appropriate) - Refactor copy_file_range and remap_range parameter checking where they are the same - Install missing copy_file_range parameter checking(!) - Remove suid/sgid and update mtime like any other file write - Change the behavior so that a copy range crossing the source file's eof will result in a short copy to the source file's eof instead of EINVAL - Permit filesystems to decide if they want to handle cross-superblock copy_file_range in their local handlers" * tag 'copy-file-range-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: fuse: copy_file_range needs to strip setuid bits and update timestamps vfs: allow copy_file_range to copy across devices xfs: use file_modified() helper vfs: introduce file_modified() helper vfs: add missing checks to copy_file_range vfs: remove redundant checks from generic_remap_checks() vfs: introduce generic_file_rw_checks() vfs: no fallback for ->copy_file_range vfs: introduce generic_copy_file_range() |
