The thing completes and doesn't hang, but I get 6 failures: Failures: generic/604 generic/633 generic/645 generic/696 generic/697 generic/732 Though these don't appear to be anything to do with netfslib (see attached). There are two cases where the mount is busy and the rest seems to be due to id-mapped mounts and/or user namespaces. The xfstest local.config file looks something like: export FSTYP=ceph export TEST_DEV=<ipaddr>:/test export TEST_DIR=/xfstest.test TEST_FS_MOUNT_OPTS='-o name=admin,mds_namespace=test,fs=test,fsc' export SCRATCH_DEV=<ipaddr>:/scratch export SCRATCH_MNT=/xfstest.scratch export MOUNT_OPTIONS='-o name=admin,mds_namespace=scratch,fs=scratch,fsc=scratch' David --- # ./check -E .exclude generic/604 generic/633 generic/645 generic/696 generic/697 generic/732 FSTYP -- ceph PLATFORM -- Linux/x86_64 andromeda 6.13.0-rc2-build3+ #5311 SMP Fri Dec 13 09:03:34 GMT 2024 MKFS_OPTIONS -- <ipaddr>:/scratch MOUNT_OPTIONS -- -o name=admin,mds_namespace=scratch,fs=scratch,fsc=scratch -o context=system_u:object_r:root_t:s0 <ipaddr>:/scratch /xfstest.scratch generic/604 2s ...

Hey David. Thanks, for the find. I've seen your mail, but it was a busy week. If you can, please open a https://tracker.ceph.com/ bug and assign it to me.

Hi Christian, Here are some miscellaneous fixes and changes for netfslib and the ceph and nfs filesystems: (1) Ignore silly-rename files from afs and nfs when building the header archive in a kernel build. (2) netfs: Fix the way read result collection applies results to folios when each folio is being read by multiple subrequests and the results come out of order. (3) netfs: Fix ENOMEM handling in buffered reads. (4) nfs: Fix an oops in nfs_netfs_init_request() when copying to the cache. (5) cachefiles: Parse the "secctx" command immediately to get the correct error rather than leaving it to the "bind" command. (6) netfs: Remove a redundant smp_rmb(). This isn't a bug per se and could be deferred. (7) netfs: Fix missing barriers by using clear_and_wake_up_bit(). (8) netfs: Work around recursion in read retry by failing and abandoning the retried subrequest if no I/O is performed. [!] NOTE: This only works around the recursion problem if the recursion keeps returning no data. If the server manages, say, to repeatedly return a single byte of data faster than the retry algorithm can complete, it will still recurse and the stack overrun may still occur. Actually fixing this requires quite an intrusive change which will hopefully make the next merge window. (9) netfs: Fix the clearance of a folio_queue when unlocking the page if we're going to want to subsequently send the queue for copying to the cache (if, for example, we're using ceph). (10) netfs: Fix the lack of cancellation of copy-to-cache when the cache for a file is temporarily disabled (for example when a DIO write is done to the file). This patch and (9) fix hangs with ceph. With these patches, I can run xfstest -g quick to completion on ceph with a local cache. The patches can also be found here with a bonus cifs patch: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=netfs-fixes Thanks, David David Howells (8): kheaders: Ignore silly-rename files netfs: Fix non-contiguous donation between completed reads netfs: Fix enomem handling in buffered reads nfs: Fix oops in nfs_netfs_init_request() when copying to cache netfs: Fix missing barriers by using clear_and_wake_up_bit() netfs: Work around recursion by abandoning retry if nothing read netfs: Fix ceph copy to cache on write-begin netfs: Fix the (non-)cancellation of copy when cache is temporarily disabled Max Kellermann (1): cachefiles: Parse the "secctx" immediately Zilin Guan (1): netfs: Remove redundant use of smp_rmb() fs/9p/vfs_addr.c | 6 +++++- fs/afs/write.c | 5 ++++- fs/cachefiles/daemon.c | 14 +++++++------- fs/cachefiles/internal.h | 3 ++- fs/cachefiles/security.c | 6 +++--- fs/netfs/buffered_read.c | 28 ++++++++++++++++------------ fs/netfs/direct_write.c | 1 - fs/netfs/read_collect.c | 33 +++++++++++++++++++-------------- fs/netfs/read_pgpriv2.c | 4 ++++ fs/netfs/read_retry.c | 6 ++++-- fs/netfs/write_collect.c | 14 +++++--------- fs/netfs/write_issue.c | 2 ++ fs/nfs/fscache.c | 9 ++++++++- fs/smb/client/cifssmb.c | 13 +++++++++---- fs/smb/client/smb2pdu.c | 9 ++++++--- include/linux/netfs.h | 6 +++--- kernel/gen_kheaders.sh | 1 + 17 files changed, 98 insertions(+), 62 deletions(-)
