This change implements Release for the FUSE filesystem
and expected behaviors of the FUSE devices.
It includes several checks for aborted connection
in the path for making a request and a function
to abort all the ongoing FUSE requests in order.
This change adds bookkeeping variables for the
FUSE request. With them, old insecure confusing
code we used to process async requests is replaced
by new clear compiling ones. Future code can take
advantage of them to have better control of each
requests.
This change decouples the code that is weakly
tied to the connection struct from connection.go,
rename variables and files with more meaningful choices,
adds detailed comments, explains lock orders,
and adds other minor improvement to make
the existing FUSE code more readable and
more organized.
Purpose is to avoid too much code in one file
and provide better structure for the
future commits.
This commit implements FUSE_SETATTR command. When a system call modifies
the metadata of a regular file or a folder by chown(2), chmod(2),
truncate(2), utime(2), or utimes(2), they should be translated to
corresponding FUSE_SETATTR command and sent to the FUSE server.
Fixes#3332
According to Linux 4.4's FUSE behavior, the flags and fh attributes in
FUSE_GETATTR are only used in read, write, and lseek. fstat(2) doesn't
use them either. Add tests to ensure the requests sent from FUSE module
are consistent with Linux's.
Updates #3655
The fuse_init_out struct changes in different FUSE kernel versions. A
FUSE server may implement older versions of fuse_init_out, but they
share common attributes from the beginning. Implement variable-length
marshallable interface to support older versions of ABI.
Fixes#3707
According to readdir(3), the offset attribute in struct dirent is the
offset to the next dirent instead of the offset of itself. Send the
successive FUSE_READDIR requests with the offset retrieved from the last
entry.
