ksmbd: avoid reclaiming expired durable opens by the client

2024-07-14T23:00:35Z

The expired durable opens should not be reclaimed by client. This patch add ->durable_scavenger_timeout to fp and check it in ksmbd_lookup_durable_fd(). Signed-off-by: Namjae Jeon Signed-off-by: Steve French

ksmbd: use rwsem instead of rwlock for lease break

2024-05-05T04:53:36Z

ksmbd: add support for durable handles v1/v2

2024-03-12T05:36:39Z

Durable file handles allow reopening a file preserved on a short network outage and transparent client reconnection within a timeout. i.e. Durable handles aren't necessarily cleaned up when the opening process terminates. This patch add support for durable handle version 1 and 2. To prove durable handles work on ksmbd, I have tested this patch with the following smbtorture tests: smb2.durable-open.open-oplock smb2.durable-open.open-lease smb2.durable-open.reopen1 smb2.durable-open.reopen1a smb2.durable-open.reopen1a-lease smb2.durable-open.reopen2 smb2.durable-open.reopen2a smb2.durable-open.reopen2-lease smb2.durable-open.reopen2-lease-v2 smb2.durable-open.reopen3 smb2.durable-open.reopen4 smb2.durable-open.delete_on_close2 smb2.durable-open.file-position smb2.durable-open.lease smb2.durable-open.alloc-size smb2.durable-open.read-only smb2.durable-v2-open.create-blob smb2.durable-v2-open.open-oplock smb2.durable-v2-open.open-lease smb2.durable-v2-open.reopen1 smb2.durable-v2-open.reopen1a smb2.durable-v2-open.reopen1a-lease smb2.durable-v2-open.reopen2 smb2.durable-v2-open.reopen2b Signed-off-by: Namjae Jeon Signed-off-by: Steve French

ksmbd: lazy v2 lease break on smb2_write()

2023-12-08T16:11:33Z

Don't immediately send directory lease break notification on smb2_write(). Instead, It postpones it until smb2_close(). Signed-off-by: Namjae Jeon Signed-off-by: Steve French

ksmbd: send v2 lease break notification for directory

2023-12-08T16:11:33Z

If client send different parent key, different client guid, or there is no parent lease key flags in create context v2 lease, ksmbd send lease break to client. Signed-off-by: Namjae Jeon Signed-off-by: Steve French

ksmbd: separately allocate ci per dentry

2023-11-24T02:50:45Z

xfstests generic/002 test fail when enabling smb2 leases feature. This test create hard link file, but removeal failed. ci has a file open count to count file open through the smb client, but in the case of hard link files, The allocation of ci per inode cause incorrectly open count for file deletion. This patch allocate ci per dentry to counts open counts for hard link. Signed-off-by: Namjae Jeon Signed-off-by: Steve French

ksmbd: fix race condition with fp

2023-10-05T01:21:48Z

fp can used in each command. If smb2_close command is coming at the same time, UAF issue can happen by race condition. Time + Thread A | Thread B1 B2 ....
