gVisor stack ignores RSTs when in TIME_WAIT which is not the default
Linux behavior. Add a packetimpact test to test the same.
Also update code comments to reflect the rationale for the current
gVisor behavior.

In Linux, FDSize is fs/proc/array.c:task_state() => struct fdtable::max_fds,
which is set to the underlying array's length in fs/file.c:alloc_fdtable().
Follow-up changes:
- Remove FDTable.GetRefs() and FDTable.GetRefsVFS2(), which are unused.
- Reset FDTable.used to 0 during restore, since the subsequent calls to
FDTable.setAll() increment it again, causing its value to be doubled. (After
this CL, FDTable.used is only used to avoid reallocation in FDTable.GetFDs(),
so this fix is not very visible.)

IPv4 can accept 65536-octet reassembled packets.
Test:
- ipv4_test.TestInvalidFragments
- ipv4_test.TestReceiveFragments
- ipv6.TestInvalidIPv6Fragments
- ipv6.TestReceiveIPv6Fragments
Fixes #3770

Fixes #3696
|
|
|
|
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 commit fixes the potential unexpected errors
of original handling of FUSE_RELEASE responses while
keep the same behavior (ignoring any reply).
|
|
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
|
|
This commit adds basic write(2) support for FUSE.
|
|
FUSE_CREATE is called when issuing creat(2) or open(2) with O_CREAT. It
creates a new file on the FUSE filesystem.
Fixes #3825
|
|
This change removes the unnecessary loop and avoids
the recursive call. It also fixes minor bugs in this
function.

This commit removes unused marshalling functions in linux abi package
and moves self-defined FUSEInitRes wrapper to fuse package.
Updates #3707
|
|
This change adds the following:
- Add support for containerizing syscall tests for FUSE
- Mount tmpfs in the container so we can run benchmarks against it
- Run the server in a background process
- benchmarks for fuse syscall

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

kernfs uses inode.Getlink to resolve symlink when look up paths.
Updates #3452
|
|
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.
Updates #3255
|
|
Until #3698 is resolved, this change is needed to ensure we're not
corrupting memory anywhere.
|
|
Fixes #3255.
This change adds support for IterDirents. You can now use `ls` in
the FUSE sandbox.

Original FUSE integration test has limited capabilities. To test more
situations, the new integration test framework introduces a protocol
to communicate between testing thread and the FUSE server. In summary,
this change includes:
1. Remove CompareResult() and break SetExpected() into
SetServerResponse() and GetServerActualRequest(). We no longer set
up an expected request because we want to retrieve the actual FUSE
request made to the FUSE server and check in the testing thread.
2. Declare a serial buffer data structure to save the received requests
and expected responses sequentially. The data structure contains a
cursor to indicate the progress of accessing. This change makes
sequential SetServerResponse() and GetServerActualRequest() possible.
3. Replace 2 single directional pipes with 1 bi-directional socketpair.
A protocol which starts with FuseTestCmd is used between the testing
thread and the FUSE server to provide various functionality.

This is very similar to copy-up-coherent mmap in the VFS1 overlay, with the
minor wrinkle that there is no fs.InodeOperations.Mappable().

Fixes an error where in case of a receive buffer larger than the host send
buffer size for a host backed unix dgram socket we would end up swallowing EOF
from recvmsg syscall causing the read() to block forever.
