The intent is to have a more complete support for file operations in io_uring. This change adds support for the following functions to io_uring: - fgetxattr - fsetxattr - getxattr - setxattr Patch 1: fs: split off do_user_path_at_empty from user_path_at_empty() This splits off a new function do_user_path_at_empty from user_path_at_empty that is based on filename and not on a user-specified string. Patch 2: fs: split off setxattr_copy and do_setxattr function from setxat= tr Split off the setup part of the setxattr function in the setxattr_copy function. Split off the processing part in do_setxattr. Patch 3: fs: split off do_getxattr from getxattr Split of the do_getxattr part from getxattr. This will allow it to be invoked it from io_uring. Patch 4: io_uring: add fsetxattr and setxattr support This adds new functions to support the fsetxattr and setxattr functions. Patch 5: io_uring: add fgetxattr and getxattr support This adds new functions to support the fgetxattr and getxattr functions. There are two additional patches: liburing: Add support for xattr api's. This also includes the tests for the new code. xfstests: Add support for io_uring xattr support. V9: - keep kvalue in struct xattr_ctx V8: - introduce xattr_name struct as advised by Linus - remove kname_sz field in xattr_ctx V7: - split off setxattr in two functions as recommeneded by Christian. V6: - reverted addition of kname array to xattr_ctx structure Adding the kname array increases the io_kiocb beyond 64 bytes (increases it to 224 bytes). We try hard to limit it to 64 bytes. Keeping the original interface also is a bit more efficient. - addressed Pavel's reordering comment - addressed Pavel's putname comment - addressed Pavel's kvfree comment - rebased on for-5.17/io_uring-getdents64 V5: - add kname array to xattr_ctx structure V4: - rebased patch series V3: - remove req->file checks in prep functions - change size parameter in do_xattr V2: - split off function do_user_path_empty instead of changing the function signature of user_path_at - Fix datatype size problem in do_getxattr Stefan Roesch (5): fs: split off do_user_path_at_empty from user_path_at_empty() fs: split off setxattr_copy and do_setxattr function from setxattr fs: split off do_getxattr from getxattr io_uring: add fsetxattr and setxattr support io_uring: add fgetxattr and getxattr support fs/internal.h | 28 +++ fs/io_uring.c | 314 ++++++++++++++++++++++++++++++++++ fs/namei.c | 10 +- fs/xattr.c | 114 ++++++++---- include/linux/namei.h | 2 + include/uapi/linux/io_uring.h | 8 +- 6 files changed, 438 insertions(+), 38 deletions(-) base-commit: b4518682080d3a1cdd6ea45a54ff6772b8b2797a --=20 2.30.2
