Bharath SM e4b61f3b1c cifs: prevent updating file size from server if we have a read/write lease ... In cases of large directories, the readdir operation may span multiple round trips to retrieve contents. This introduces a potential race condition in case of concurrent write and readdir operations. If the readdir operation initiates before a write has been processed by the server, it may update the file size attribute to an older value. Address this issue by avoiding file size updates from readdir when we have read/write lease. Scenario: 1) process1: open dir xyz 2) process1: readdir instance 1 on xyz 3) process2: create file.txt for write 4) process2: write x bytes to file.txt 5) process2: close file.txt 6) process2: open file.txt for read 7) process1: readdir 2 - overwrites file.txt inode size to 0 8) process2: read contents of file.txt - bug, short read with 0 bytes Cc: stable@vger.kernel.org Reviewed-by: Shyam Prasad N <sprasad@microsoft.com> Signed-off-by: Bharath SM <bharathsm@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com>		2024-03-10 19:33:53 -05:00
