Merge tag 'v7.2-rc-part2-smb3-server-fixes' of git://git.samba.org/ksmbd
Pull smb server updates from Steve French:
"This is mostly a correctness and compatibility update for ksmbd's
SMB2/3 lease, oplock, durable handle, compound request, CREATE,
rename, stream and share-mode handling.
A large part of the series fixes cases found by smbtorture where ksmbd
diverged from the SMB2/3 protocol requirements.
The main changes are:
- Rework SMB2 lease state handling so lease state is shared per
ClientGuid/LeaseKey across opens, with better validation of lease
create contexts, ACK handling, epochs, break-in-progress reporting,
v2 lease notification routing, and chained lease breaks
- Fix several oplock break corner cases, including ACK validation,
timeout downgrade behavior, level-II break handling on unlink,
share-conflict lease breaks, and read-control/stat-open behavior
- Fix durable handle behavior around delete-on-close, stale
reconnects, reconnect context parsing, oplock/lease break
invalidation, and durable v2 AppInstanceId replacement
- Fix compound request handling so related commands propagate failed
statuses correctly, preserve response framing across chained
errors, keep compound FIDs across READ/WRITE/FLUSH, and send
interim STATUS_PENDING where clients expect cancellable compound
I/O
- Tighten CREATE and stream semantics, including create attribute
validation, allocation size reporting, explicit create security
descriptors, unnamed DATA stream handling, stream directory
validation, and stream delete sharing against the base file
- Fix rename and metadata behavior, including parent directory
sharing checks, denying directory rename with open children, and
preserving SMB ChangeTime across rename for open handles
- Fix two important safety issues: a multichannel byte-range lock
list owner race that could lead to use-after-free, and an NTLMv2
session key update before authentication proof validation
- Fix a concurrent SMB2 NEGOTIATE preauth use-after-free, a UBSAN
warning in compression capability parsing, a false hung-task
warning in the durable handle scavenger, endian debug logging,
Smatch indentation warnings, and kernel-doc warnings
- Increase the default SMB3 transaction size from 1MB to 4MB to
better match modern read/write negotiation and improve sequential
I/O behavior"
