Date: Wed, 24 Oct 2018 00:57:43 +0100 From: David Howells <dhowells@...hat.com> To: viro@...iv.linux.org.uk Cc: dhowells@...hat.com, linux-afs@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH 00/25] AFS development [ver #2] Hi Al, Here's a set of development patches for AFS if you could pull it for the upcoming merge window. Its main features are: (1) Provide wrapper functions for accessing iov iterators and provide a new read discard iterator type (ITER_DISCARD). (2) Use iov iterators more directly in AFS unmarshalling routines. (3) Support for retrieving DNS information where the VL server address list is partitioned by server. (4) Implement VL server rotation and improve both this and FS server rotation. (5) Add support for the YFS variant of the AFS server. (6) When first attempting to use a server or a list of servers, plumb all the addresses simultaneously to try and determine the best route. The patches are tagged here: git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git afs-next-20181024 and can also be found on the following branch: http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=afs-next David --- David Howells (25): amd-gpu: Don't undefine READ and WRITE iov_iter: Use accessor function iov_iter: Separate type from direction and use accessor functions iov_iter: Add I/O discard iterator afs: Better tracing of protocol errors afs: Set up the iov_iter before calling afs_extract_data() afs: Improve FS server rotation error handling afs: Implement VL server rotation afs: Fix TTL on VL server and address lists afs: Handle EIO from delivery function afs: Add a couple of tracepoints to log I/O errors afs: Don't invoke the server to read data beyond EOF afs: Increase to 64-bit volume ID and 96-bit vnode ID for YFS afs: Commit the status on a new file/dir/symlink afs: Remove callback details from afs_callback_break struct afs: Implement the YFS cache manager service afs: Fix FS.FetchStatus delivery from updating wrong vnode afs: Calc callback expiry in op reply delivery afs: Get the target vnode in afs_rmdir() and get a callback on it afs: Expand data structure fields to support YFS afs: Implement YFS support in the fs client afs: Allow dumping of server cursor on operation failure afs: Eliminate the address pointer from the address list cursor afs: Fix callback handling afs: Probe multiple fileservers simultaneously block/bio.c | 2 drivers/block/drbd/drbd_main.c | 2 drivers/block/drbd/drbd_receiver.c | 2 drivers/block/loop.c | 9 drivers/block/nbd.c | 12 drivers/fsi/fsi-sbefifo.c | 4 drivers/gpu/drm/amd/display/dc/os_types.h | 2 drivers/isdn/mISDN/l1oip_core.c | 3 drivers/misc/vmw_vmci/vmci_queue_pair.c | 6 drivers/nvme/target/io-cmd-file.c | 2 drivers/target/iscsi/iscsi_target_util.c | 6 drivers/target/target_core_file.c | 6 drivers/usb/usbip/usbip_common.c | 2 drivers/xen/pvcalls-back.c | 8 fs/9p/vfs_addr.c | 4 fs/9p/vfs_dir.c | 2 fs/9p/xattr.c | 4 fs/afs/Kconfig | 12 fs/afs/Makefile | 7 fs/afs/addr_list.c | 209 ++- fs/afs/afs.h | 50 - fs/afs/cache.c | 2 fs/afs/callback.c | 17 fs/afs/cell.c | 65 + fs/afs/cmservice.c | 287 +++- fs/afs/dir.c | 75 + fs/afs/dynroot.c | 4 fs/afs/file.c | 8 fs/afs/flock.c | 22 fs/afs/fs_probe.c | 270 ++++ fs/afs/fsclient.c | 583 ++++---- fs/afs/inode.c | 37 fs/afs/internal.h | 322 ++++ fs/afs/mntpt.c | 5 fs/afs/proc.c | 110 + fs/afs/protocol_yfs.h | 163 ++ fs/afs/rotate.c | 302 +++- fs/afs/rxrpc.c | 115 +- fs/afs/security.c | 13 fs/afs/server.c | 145 -- fs/afs/server_list.c | 6 fs/afs/super.c | 5 fs/afs/vl_list.c | 340 +++++ fs/afs/vl_probe.c | 273 ++++ fs/afs/vl_rotate.c | 355 +++++ fs/afs/vlclient.c | 195 +-- fs/afs/volume.c | 56 - fs/afs/write.c | 30 fs/afs/xattr.c | 2 fs/afs/yfsclient.c | 2184 +++++++++++++++++++++++++++++ fs/block_dev.c | 2 fs/ceph/file.c | 7 fs/cifs/connect.c | 4 fs/cifs/file.c | 4 fs/cifs/misc.c | 4 fs/cifs/smb2ops.c | 4 fs/cifs/smbdirect.c | 17 fs/cifs/transport.c | 8 fs/direct-io.c | 2 fs/dlm/lowcomms.c | 2 fs/fuse/file.c | 2 fs/iomap.c | 2 fs/nfsd/vfs.c | 4 fs/ocfs2/cluster/tcp.c | 2 fs/orangefs/inode.c | 2 fs/splice.c | 7 include/linux/uio.h | 65 + include/trace/events/afs.h | 213 +++ lib/iov_iter.c | 125 +- mm/filemap.c | 2 mm/page_io.c | 2 net/9p/client.c | 2 net/9p/trans_virtio.c | 2 net/bluetooth/6lowpan.c | 2 net/bluetooth/a2mp.c | 2 net/bluetooth/smp.c | 2 net/ceph/messenger.c | 6 net/netfilter/ipvs/ip_vs_sync.c | 2 net/smc/smc_clc.c | 4 net/socket.c | 6 net/sunrpc/svcsock.c | 2 net/tipc/topsrv.c | 2 net/tls/tls_device.c | 4 net/tls/tls_sw.c | 4 84 files changed, 5629 insertions(+), 1236 deletions(-) create mode 100644 fs/afs/fs_probe.c create mode 100644 fs/afs/protocol_yfs.h create mode 100644 fs/afs/vl_list.c create mode 100644 fs/afs/vl_probe.c create mode 100644 fs/afs/vl_rotate.c create mode 100644 fs/afs/yfsclient.c
