differently.

Fixes #3696
|
|
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

fuse_util provides utilities for fuse testing. Add a function to return
a stub fuse_attr struct with specified mode and nodeid.
|
|
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 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

Fixes #3255.
This change adds support for IterDirents. You can now use `ls` in
the FUSE sandbox.

Adds a function for the testing thread to set up a fake inode with a
specific path under mount point. After this function is called, each
subsequent FUSE_LOOKUP request with the same path will be served with
the fixed stub response.

This commit adds a function in the newly created fuse_util library,
which accepts a variable number of arguments and data structures.
Fixes #3609

This commit adds 3 utility functions to ensure all received requests
and preset responses are consumed.
1. Get number of unconsumed requests (received by the FUSE server but
not consumed by the testing thread).
2. Get number of unsent responses (set by the testing thread but not
processed by the FUSE server).
3. Get total bytes of the received requests (to ensure some operations
don't trigger FUSE requests).
Fixes #3607

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.
Fixes #3405

Make setting STATX_SIZE a no-op, if it is valid for the given permissions and
file type.
Also update proc tests, which were overfitted before.
Fixes #3842.

Currently the returned offset is an index, and we can't
use it to find the next fd to serialize, because getdents
should iterate correctly despite mutation of fds. Instead,
we can return the next fd to serialize plus 2 (which
accounts for "." and "..") as the offset.

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.

These operations require CAP_SYS_ADMIN in the root user namespace. There's no
easy way to check that other than trying the operation and seeing what happens.

Packetimpact on Fuchsia was formerly using the Linux test device name. This
change fixes that.

Overlayfs does not persist a directory's inode number even while it is mounted.
See fs/overlayfs/inode.c:ovl_map_dev_ino(). VFS2 generates a new inode number
for directories everytime in lookup.
PiperOrigin-RevId: 331045037

Overlayfs intentionally does not compute nlink for directories (because it can
be really expensive). Linux returns 1, VFS2 returns 2 and VFS1 actually
calculates the correct value.

- BindSocketThenOpen test was expecting the incorrect error when opening
a socket. Fixed that.
- VirtualFilesystem.BindEndpointAt should not require pop.Path.Begin.Ok()
because the filesystem implementations do not need to walk to the parent
dentry. This check also exists for MknodAt, MkdirAt, RmdirAt, SymlinkAt and
UnlinkAt but those filesystem implementations also need to walk to the parent
denty. So that check is valid. Added some syscall tests to test this.

The existing implementation for TransportProtocol.{Set}Option take
arguments of an empty interface type which all types (implicitly)
implement; any type may be passed to the functions.
This change introduces marker interfaces for transport protocol options
that may be set or queried which transport protocol option types
implement to ensure that invalid types are caught at compile time.
Different interfaces are used to allow the compiler to enforce read-only
or set-only socket options.

Accept on gVisor will return an error if a socket in the accept queue was closed
before Accept() was called. Linux will return the new fd even if the returned
socket is already closed by the peer say due to a RST being sent by the peer.
This seems to be intentional in linux more details on the github issue.

Adds docs to nginx and refactors both Httpd and Nginx benchmarks.
Key changes:
- Add docs and make nginx tests the same as httpd (reverse, all docs, etc.).
- Make requests scale on c * b.N -> a request per thread. This works well
with both --test.benchtime=10m (do a run that lasts at least 10m) and
--test.benchtime=10x (do b.N = 10).
-- Remove a doc from both tests (1000Kb) as 1024Kb exists.

This is to cover the common pattern: open->read/write->close,
where SetAttr needs to be called to update atime/mtime before
the file is closed.
Benchmark results:
BM_OpenReadClose/10240 CPU
setattr+clunk: 63783 ns
VFS2: 68109 ns
VFS1: 72507 ns

On receiving an ACK with unacceptable ACK number, in a closing state,
TCP, needs to reply back with an ACK with correct seq and ack numbers and
remain in same state. This change is as per RFC793 page 37, but with a
difference that it does not apply to ESTABLISHED state, just as in Linux.
Also add more tests to check for OTW sequence number and unacceptable
ack numbers in these states.
