The NetDIM library, currently leveraged by an array of NICs, delivers
excellent acceleration benefits. Nevertheless, NICs vary significantly
in their dim profile list prerequisites.
Specifically, virtio-net backends may present diverse sw or hw device
implementation, making a one-size-fits-all parameter list impractical.
On Alibaba Cloud, the virtio DPU's performance under the default DIM
profile falls short of expectations, partly due to a mismatch in
parameter configuration.
I also noticed that ice/idpf/ena and other NICs have customized
profilelist or placed some restrictions on dim capabilities.
Motivated by this, I tried adding new params for "ethtool -C" that provides
a per-device control to modify and access a device's interrupt parameters.
Usage
========
The target NIC is named ethx.
Assume that ethx only declares support for rx profile setting
(with DIM_PROFILE_RX flag set in profile_flags) and supports modification
of usec and pkt fields.
1. Query the currently customized list of the device
$ ethtool -c ethx
...
rx-profile:
{.usec = 1, .pkts = 256, .comps = n/a,},
{.usec = 8, .pkts = 256, .comps = n/a,},
{.usec = 64, .pkts = 256, .comps = n/a,},
{.usec = 128, .pkts = 256, .comps = n/a,},
{.usec = 256, .pkts = 256, .comps = n/a,}
tx-profile: n/a
2. Tune
$ ethtool -C ethx rx-profile 1,1,n_2,n,n_3,3,n_4,4,n_n,5,n
"n" means do not modify this field.
$ ethtool -c ethx
...
rx-profile:
{.usec = 1, .pkts = 1, .comps = n/a,},
{.usec = 2, .pkts = 256, .comps = n/a,},
{.usec = 3, .pkts = 3, .comps = n/a,},
{.usec = 4, .pkts = 4, .comps = n/a,},
{.usec = 256, .pkts = 5, .comps = n/a,}
tx-profile: n/a
3. Hint
If the device does not support some type of customized dim profiles,
the corresponding "n/a" will display.
If the "n/a" field is being modified, -EOPNOTSUPP will be reported.

Add ioctl()s to translate pids between pid namespaces.
LXCFS is a tiny fuse filesystem used to virtualize various aspects of
procfs. LXCFS is run on the host. The files and directories it creates
can be bind-mounted by e.g. a container at startup and mounted over the
various procfs files the container wishes to have virtualized. When e.g.
a read request for uptime is received, LXCFS will receive the pid of the
reader. In order to virtualize the corresponding read, LXCFS needs to
know the pid of the init process of the reader's pid namespace. In order
to do this, LXCFS first needs to fork() two helper processes. The first
helper process setns() to the readers pid namespace. The second helper
process is needed to create a process that is a proper member of the pid
namespace. The second helper process then creates a ucred message with
ucred.pid set to 1 and sends it back to LXCFS. The kernel will translate
the ucred.pid field to the corresponding pid number in LXCFS's pid
namespace. This way LXCFS can learn the init pid number of the reader's
pid namespace and can go on to virtualize. Since these two forks() are
costly LXCFS maintains an init pid cache that caches a given pid for a
fixed amount of time. The cache is pruned during new read requests.
However, even with the cache the hit of the two forks() is singificant
when a very large number of containers are running. With this simple
patch we add an ns ioctl that let's a caller retrieve the init pid nr of
a pid namespace through its pid namespace fd. This significantly
improves performance with a very simple change.
Support translation of pids and tgids. Other concepts can be added but
there are no obvious users for this right now.
To protect against races pidfds can be used to check whether the process
is still valid. If needed, this can also be extended to work on pidfds
directly.

nft_ctx is huge and most of the information stored within isn't used
at all.
Remove nft_ctx member from the base transaction structure and store
only what is needed.
After this change, relevant struct sizes are:
struct nft_trans_chain { /* size: 120 (-32), cachelines: 2, members: 10 */
struct nft_trans_elem { /* size: 72 (-40), cachelines: 2, members: 4 */
struct nft_trans_flowtable { /* size: 80 (-48), cachelines: 2, members: 5 */
struct nft_trans_obj { /* size: 72 (-40), cachelines: 2, members: 4 */
struct nft_trans_rule { /* size: 80 (-32), cachelines: 2, members: 6 */
struct nft_trans_set { /* size: 96 (-24), cachelines: 2, members: 8 */
struct nft_trans_table { /* size: 56 (-40), cachelines: 1, members: 2 */
struct nft_trans_elem can now be allocated from kmalloc-96 instead of
kmalloc-128 slab.
A further reduction by 8 bytes would even allow for kmalloc-64.

There is 'struct nft_trans', the basic structure for all transactional
objects, and the the various different transactional objects, such as
nft_trans_table, chain, set, set_elem and so on.
Right now 'struct nft_trans' uses a flexible member at the tail
(data[]), and casting is needed to access the actual type-specific
members.
Change this to make the hierarchy visible in source code, i.e. make
struct nft_trans the first member of all derived subtypes.
This has several advantages:
1. pahole output reflects the real size needed by the particular subtype
2. allows to use container_of() to convert the base type to the actual
object type instead of casting ->data to the overlay structure.
3. It makes it easy to add intermediate types.
'struct nft_trans' contains a 'binding_list' that is only needed
by two subtypes, so it should be part of the two subtypes, not in
the base structure.
But that makes it hard to interate over the binding_list, because
there is no common base structure.
A follow patch moves the bind list to a new struct:
struct nft_trans_binding {
struct nft_trans nft_trans;
struct list_head binding_list;
};
... and makes that structure the new 'first member' for both
nft_trans_chain and nft_trans_set.
No functional change intended in this patch.
Some numbers:
struct nft_trans { /* size: 88, cachelines: 2, members: 5 */
struct nft_trans_chain { /* size: 152, cachelines: 3, members: 10 */
struct nft_trans_elem { /* size: 112, cachelines: 2, members: 4 */
struct nft_trans_flowtable { /* size: 128, cachelines: 2, members: 5 */
struct nft_trans_obj { /* size: 112, cachelines: 2, members: 4 */
struct nft_trans_rule { /* size: 112, cachelines: 2, members: 5 */
struct nft_trans_set { /* size: 120, cachelines: 2, members: 8 */
struct nft_trans_table { /* size: 96, cachelines: 2, members: 2 */
Of particular interest is nft_trans_elem, which needs to be allocated
once for each pending (to be added or removed) set element.
Add BUILD_BUG_ON to check struct nft_trans is placed at the top of
the container structure.

A couple of declarations in linux/syscalls.h are missing __user

Most architectures that implement the old-style mmap() with byte offset
use 'unsigned long' as the type for that offset, but microblaze and
riscv have the off_t type that is shared with userspace, matching the
prototype in include/asm-generic/syscalls.h.
Make this consistent by using an unsigned argument everywhere. This
changes the behavior slightly, as the argument is shifted to a page
number, and an user input with the top bit set would result in a
negative page offset rather than a large one as we use elsewhere.
For riscv, the 32-bit sys_mmap2() definition actually used a custom
type that is different from the global declaration, but this was
missed due to an incorrect type check.

Using sys_io_pgetevents() as the entry point for compat mode tasks
works almost correctly, but misses the sign extension for the min_nr
and nr arguments.
This was addressed on parisc by switching to
compat_sys_io_pgetevents_time64() in commit 6431e92fc827 ("parisc:
io_pgetevents_time64() needs compat syscall in 32-bit compat mode"),
as well as by using more sophisticated system call wrappers on x86 and
s390. However, arm64, mips, powerpc, sparc and riscv still have the
same bug.
Change all of them over to use compat_sys_io_pgetevents_time64()
like parisc already does. This was clearly the intention when the
function was originally added, but it got hooked up incorrectly in
the tables.

1394 OHCI hardware triggers PCI interrupts to notify any events to
software. Current driver for the hardware is programmed by the typical
way to utilize top- and bottom- halves, thus it has a timing gap to handle
the notification in softIRQ (tasklet).
This commit adds a tracepoint event for the hardIRQ event. The comparison
of the tracepoint event to tracepoints events in firewire subsystem is
helpful to diagnose the timing gap.

When bonding is configured in BOND_MODE_BROADCAST mode, if two identical
SYN packets are received at the same time and processed on different CPUs,
it can potentially create the same sk (sock) but two different reqsk
(request_sock) in tcp_conn_request().
These two different reqsk will respond with two SYNACK packets, and since
the generation of the seq (ISN) incorporates a timestamp, the final two
SYNACK packets will have different seq values.
The consequence is that when the Client receives and replies with an ACK
to the earlier SYNACK packet, we will reset(RST) it.
========================================================================
This behavior is consistently reproducible in my local setup,
which comprises:
| NETA1 ------ NETB1 |
PC_A --- bond --- | | --- bond --- PC_B
| NETA2 ------ NETB2 |
- PC_A is the Server and has two network cards, NETA1 and NETA2. I have
bonded these two cards using BOND_MODE_BROADCAST mode and configured
them to be handled by different CPU.
- PC_B is the Client, also equipped with two network cards, NETB1 and
NETB2, which are also bonded and configured in BOND_MODE_BROADCAST mode.
If the client attempts a TCP connection to the server, it might encounter
a failure. Capturing packets from the server side reveals:
10.10.10.10.45182 > localhost: Flags [S], seq 320236027,
10.10.10.10.45182 > localhost: Flags [S], seq 320236027,
localhost > 10.10.10.10.45182: Flags [S.], seq 2967855116,
localhost > 10.10.10.10.45182: Flags [S.], seq 2967855123, <==
10.10.10.10.45182 > localhost: Flags [.], ack 4294967290,
10.10.10.10.45182 > localhost: Flags [.], ack 4294967290,

localhost > 10.10.10.10.45182: Flags [R], seq 2967855117,
Two SYNACKs with different seq numbers are sent by localhost,
resulting in an anomaly.
========================================================================
The attempted solution is as follows:
Add a return value to inet_csk_reqsk_queue_hash_add() to confirm if the
ehash insertion is successful (Up to now, the reason for unsuccessful
insertion is that a reqsk for the same connection has already been
inserted). If the insertion fails, release the reqsk.
Due to the refcnt, Kuniyuki suggests also adding a return value check
for the DCCP module; if ehash insertion fails, indicating a successful
insertion of the same connection, simply release the reqsk as well.
Simultaneously, In the reqsk_queue_hash_req(), the start of the
req->rsk_timer is adjusted to be after successful insertion.

Now that cpumask types are split out to a separate smaller header, many
frequently included core headers may switch to using it.

sched.h needs cpumask.h mostly for types declaration. Now that we have
cpumask_types.h, which is a significantly smaller header, we can rely on
it.
The only exception is UP stub for set_cpus_allowed_ptr(). The function
needs to test bit #0 in a @new_mask, which can be trivially opencoded.

Many core headers, like sched.h, include cpumask.h mostly for struct
cpumask and cpumask_var_t. Those are frequently used headers and
shouldn't pull more than the bare minimum.

<linux/sched.h> indirectly via cpumask.h path includes the ilog2.h header
to calculate ilog2(TASK_REPORT_MAX). The following patches drops sched.h
dependency on cpumask.h, and to have a successful build, the header has to
be included explicitly.
sched.h is a frequently included header, and it's better to keep the
dependency list as small as possible. So, instead of including ilog2.h
for a single BUILD_BUG_ON() check, the same check may be implemented by
taking exponent of the other part of equation.
