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.
Updates #1193.

The refactor aims to simplify the package, by replacing the Go channel with a
PacketBuffer slice.
This code will be reused by tests for IPv6 fragmentation.

This is needed for SO_LINGER, where close() is blocked for linger timeout and
we are holding the FDTable lock for the entire timeout which will not allow
us to create/delete other fds. We have to release the locks and then drop the
fds.

Discovered by ayushranjan@:
VFS2 was employing the following algorithm for fetching ready events from an
epoll instance:
- Create a statically sized EpollEvent slice on the stack of size 16.
- Pass that to EpollInstance.ReadEvents() to populate.
- EpollInstance.ReadEvents() requeues level-triggered events that it returns
back into the ready queue.
- Write the results to usermem.
- If the number of results were = 16 then recall EpollInstance.ReadEvents() in
the hopes of getting more. But this will cause duplication of the "requeued"
ready level-triggered events.
So if the ready queue has >= 16 ready events, the EpollWait for loop will spin
until it fills the usermem with `maxEvents` events.
Fixes #3521

The routing table (in its current) form should not be used to make
decisions about whether a remote address is a broadcast address or
not (for IPv4).
Note, a destination subnet does not always map to a network.
E.g. RouterA may have a route to 192.168.0.0/22 through RouterB,
but RouterB may be configured with 4x /24 subnets on 4 different
interfaces.
See https://github.com/google/gvisor/issues/3938.

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.

This is simpler and more performant.

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.
