ksmbd: browse interfaces list on FSCTL_QUERY_INTERFACE_INFO IOCTL2025-01-16T05:24:51+00:00Namjae Jeonlinkinjeon@kernel.org2025-01-10T04:37:05+00:00urn:sha1:b2d99376c5d61eb60ffdb6c503e4b6c8f9712ddd
ksmbd.mount will give each interfaces list and bind_interfaces_only flags
to ksmbd server. Previously, the interfaces list was sent only
when bind_interfaces_only was enabled.
ksmbd server browse only interfaces list given from ksmbd.conf on
FSCTL_QUERY_INTERFACE_INFO IOCTL.

ksmbd: fix broken transfers when exceeding max simultaneous operations2024-12-16T04:20:03+00:00Marios Makassikismmakassikis@freebox.fr2024-12-14T03:17:23+00:00urn:sha1:43fb7bce8866e793275c4f9f25af6a37745f3416
Since commit 0a77d947f599 ("ksmbd: check outstanding simultaneous SMB
operations"), ksmbd enforces a maximum number of simultaneous operations
for a connection. The problem is that reaching the limit causes ksmbd to
close the socket, and the client has no indication that it should have
slowed down.
This behaviour can be reproduced by setting "smb2 max credits = 128" (or
lower), and transferring a large file (25GB).
smbclient fails as below:
$ smbclient //192.168.1.254/testshare -U user%pass
smb: \> put file.bin
cli_push returned NT_STATUS_USER_SESSION_DELETED
putting file file.bin as \file.bin smb2cli_req_compound_submit:
Insufficient credits. 0 available, 1 needed
NT_STATUS_INTERNAL_ERROR closing remote file \file.bin
smb: \> smb2cli_req_compound_submit: Insufficient credits. 0 available,
1 needed
Windows clients fail with 0x8007003b (with smaller files even).
Fix this by delaying reading from the socket until there's room to
allocate a request. This effectively applies backpressure on the client,
so the transfer completes, albeit at a slower rate.

smb: move client and server files to common directory fs/smb2023-05-24T21:29:21+00:00Steve Frenchstfrench@microsoft.com2023-05-22T01:46:30+00:00urn:sha1:38c8a9a52082579090e34c033d439ed2cd1a462d
Move CIFS/SMB3 related client and server files (cifs.ko and ksmbd.ko
and helper modules) to new fs/smb subdirectory:
fs/cifs --> fs/smb/client
fs/ksmbd --> fs/smb/server
fs/smbfs_common --> fs/smb/common
