Merge tag 'clone3-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull clone3 system call from Christian Brauner:
"This adds the clone3 syscall which is an extensible successor to clone
after we snagged the last flag with CLONE_PIDFD during the 5.2 merge
window for clone(). It cleanly supports all of the flags from clone()
and thus all legacy workloads.
There are few user visible differences between clone3 and clone.
First, CLONE_DETACHED will cause EINVAL with clone3 so we can reuse
this flag. Second, the CSIGNAL flag is deprecated and will cause
EINVAL to be reported. It is superseeded by a dedicated "exit_signal"
argument in struct clone_args thus freeing up even more flags. And
third, clone3 gives CLONE_PIDFD a dedicated return argument in struct
clone_args instead of abusing CLONE_PARENT_SETTID's parent_tidptr
argument.
The clone3 uapi is designed to be easy to handle on 32- and 64 bit:
/* uapi */
struct clone_args {
__aligned_u64 flags;
__aligned_u64 pidfd;
__aligned_u64 child_tid;
__aligned_u64 parent_tid;
__aligned_u64 exit_signal;
__aligned_u64 stack;
__aligned_u64 stack_size;
__aligned_u64 tls;
};
and a separate kernel struct is used that uses proper kernel typing:
/* kernel internal */
struct kernel_clone_args {
u64 flags;
int __user *pidfd;
int __user *child_tid;
int __user *parent_tid;
int exit_signal;
unsigned long stack;
unsigned long stack_size;
unsigned long tls;
};
The system call comes with a size argument which enables the kernel to
detect what version of clone_args userspace is passing in. clone3
validates that any additional bytes a given kernel does not know about
are set to zero and that the size never exceeds a page.
A nice feature is that this patchset allowed us to cleanup and
simplify various core kernel codepaths in kernel/fork.c by making the
internal _do_fork() function take struct kernel_clone_args even for
legacy clone().
This patch also unblocks the time namespace patchset which wants to
introduce a new CLONE_TIMENS flag.
Note, that clone3 has only been wired up for x86{_32,64}, arm{64}, and
xtensa. These were the architectures that did not require special
massaging.
Other architectures treat fork-like system calls individually and
after some back and forth neither Arnd nor I felt confident that we
dared to add clone3 unconditionally to all architectures. We agreed to
leave this up to individual architecture maintainers. This is why
there's an additional patch that introduces __ARCH_WANT_SYS_CLONE3
which any architecture can set once it has implemented support for
clone3. The patch also adds a cond_syscall(clone3) for architectures
such as nios2 or h8300 that generate their syscall table by simply
including asm-generic/unistd.h. The hope is to get rid of
__ARCH_WANT_SYS_CLONE3 and cond_syscall() rather soon"

Merge tag 'pidfd-updates-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull pidfd updates from Christian Brauner:
"This adds two main features.
- First, it adds polling support for pidfds. This allows process
managers to know when a (non-parent) process dies in a race-free
way.
The notification mechanism used follows the same logic that is
currently used when the parent of a task is notified of a child's
death. With this patchset it is possible to put pidfds in an
{e}poll loop and get reliable notifications for process (i.e.
thread-group) exit.
- The second feature compliments the first one by making it possible
to retrieve pollable pidfds for processes that were not created
using CLONE_PIDFD.
A lot of processes get created with traditional PID-based calls
such as fork() or clone() (without CLONE_PIDFD). For these
processes a caller can currently not create a pollable pidfd. This
is a problem for Android's low memory killer (LMK) and service
managers such as systemd.
Both patchsets are accompanied by selftests.
It's perhaps worth noting that the work done so far and the work done
in this branch for pidfd_open() and polling support do already see
some adoption:
- Android is in the process of backporting this work to all their LTS
kernels [1]
- Service managers make use of pidfd_send_signal but will need to
wait until we enable waiting on pidfds for full adoption.
- And projects I maintain make use of both pidfd_send_signal and
CLONE_PIDFD [2] and will use polling support and pidfd_open() too"

incorrectly match an entry from another, though we haven't seen this
in production. This is the last remaining container bug that I'm
aware of; at this point you should be able to run separate nfsd's in
each network namespace, each with their own set of exports, and
everything should work.

"This fixes numerous parameter checking problems and inconsistent

Now the system call will actually check its range parameters

In some cases, using the 'truncate' command to extend a UDF file results
in a mismatch between the length of the file's extents (specifically, due
to incorrect length of the final NOT_ALLOCATED extent) and the information
(file) length. The discrepancy can prevent other operating systems
(i.e., Windows 10) from opening the file.
Two particular errors have been observed when extending a file:
1. The final extent is larger than it should be, having been rounded up
to a multiple of the block size.
B. The final extent is not shorter than it should be, due to not having
been updated when the file's information length was increased.

netfilter: add hardware offload infrastructure
This patchset adds support for Netfilter hardware offloads.
This patchset reuses the existing block infrastructure, the
netdev_ops->ndo_setup_tc() interface, TC_SETUP_CLSFLOWER classifier and
the flow rule API.
Patch #1 adds flow_block_cb_setup_simple(), most drivers do the same thing
to set up flow blocks, to reduce the number of changes, consolidate
codebase. Use _simple() postfix as requested by Jakub Kicinski.
This new function resides in net/core/flow_offload.c
Patch #2 renames TC_BLOCK_{UN}BIND to FLOW_BLOCK_{UN}BIND.
Patch #3 renames TCF_BLOCK_BINDER_TYPE_* to FLOW_BLOCK_BINDER_TYPE_*.
Patch #4 adds flow_block_cb_alloc() and flow_block_cb_free() helper
functions, this is the first patch of the flow block API.
Patch #5 adds the helper to deal with list operations in the flow block API.
This includes flow_block_cb_lookup(), flow_block_cb_add() and
flow_block_cb_remove().
Patch #6 adds flow_block_cb_priv(), flow_block_cb_incref() and
flow_block_cb_decref() which completes the flow block API.
Patch #7 updates the cls_api to use the flow block API from the new
tcf_block_setup(). This infrastructure transports these objects
via list (through the tc_block_offload object) back to the core
for registration.
CLS_API DRIVER
TC_SETUP_BLOCK ----------> setup flow_block_cb object &
it adds object to flow_block_offload->cb_list
|
CLS_API <-----------------------'
registers list with flow blocks
flow_block_cb & travels back to
calls ->reoffload the core for registration
drivers allocate and sets up (configure the blocks), then
registration happens from the core (cls_api and netfilter).
Patch #8 updates drivers to use the flow block API.
Patch #9 removes the tcf block callback API, which is replaced by the
flow block API.
Patch #10 adds the flow_block_cb_is_busy() helper to check if the block
is already used by a subsystem. This helper is invoked from
drivers. Once drivers are updated to support for multiple
subsystems, they can remove this check.
Patch #11 rename tc structure and definitions for the block bind/unbind
path.
Patch #12 introduces basic netfilter hardware offload infrastructure
for the ingress chain. This includes 5-tuple exact matching
and accept / drop rule actions. Only basechains are supported
at this stage, no .reoffload callback is implemented either.
Default policy to "accept" is only supported for now.
table netdev filter {
chain ingress {
type filter hook ingress device eth0 priority 0; flags offload;
ip daddr 192.168.0.10 tcp dport 22 drop
}
}
This patchset reuses the existing tcf block callback API and it places it
in the flow block callback API in net/core/flow_offload.c.
This series aims to address Jakub and Jiri's feedback, please see specific
patches in this batch for changelog in this v4.

This patch adds hardware offload support for nftables through the
existing netdev_ops->ndo_setup_tc() interface, the TC_SETUP_CLSFLOWER
classifier and the flow rule API. This hardware offload support is
available for the NFPROTO_NETDEV family and the ingress hook.
Each nftables expression has a new ->offload interface, that is used to
populate the flow rule object that is attached to the transaction
object.
There is a new per-table NFT_TABLE_F_HW flag, that is set on to offload
an entire table, including all of its chains.
This patch supports for basic metadata (layer 3 and 4 protocol numbers),
5-tuple payload matching and the accept/drop actions; this also includes
basechain hardware offload only.

Most drivers do the same thing to set up the flow block callbacks, this
patch adds a helper function to do this.
This preparation patch reduces the number of changes to adapt the
existing drivers to use the flow block callback API.
This new helper function takes a flow block list per-driver, which is
set to NULL until this driver list is used.
This patch also introduces the flow_block_command and
flow_block_binder_type enumerations, which are renamed to use
FLOW_BLOCK_* in follow up patches.
There are three definitions (aliases) in order to reduce the number of
updates in this patch, which go away once drivers are fully adapted to
use this flow block API.

The main purpose of this patch series is to extend the

The offset and bitmap of some registers of HI13X1_GMAC
are different from hip04_eth common soc. In addition,
the definition of send descriptor and parsing descriptor
are different from hip04_eth common soc. So the macro

The buf unit size of HI13X1_GMAC is cache_line_size,
which is 64, so the address we write to the buf register
needs to be shifted right by 6 bits.

HI13X1_GMAC changed the offsets and bitmaps for
GE_TX_LOCAL_PAGE_REG registers in the same peripheral
device on different models of the hip04_eth. With the
default configuration, HI13X1_GMAC can also work without
any writes to the GE_TX_LOCAL_PAGE_REG register.
