Pull smb server fixes from Steve French:
"ksmbd server fixes, mostly addressing malformed SMB request
handling and connection/session lifetime issues, including
two information-disclosure or memory-safety bugs in the SMB2
request/response paths.
- validate FILE_ALLOCATION_INFORMATION before block rounding to
prevent a client-controlled overflow from truncating a file.
- pin connections while asynchronous oplock and lease-break
notifications are pending.
- initialize compound SMB2 READ alignment padding, preventing
disclosure of uninitialized heap bytes.
- release the allocated alternate-stream xattr name after rename.
- size multichannel binding session-key buffers for the largest
permitted key, avoiding a stack buffer overflow.
- remove a disconnecting connection's channels from every session,
including channels whose binding state has since changed.
- serialize binding preauthentication-session lookup and update
against its teardown.
- check that every compound request element contains StructureSize2
before reading it"
