When ur_load_imm_any() is inlined into jeq_imm(), it's possible for the
compiler to deduce a case where _val can only have the value of -1 at
compile time. Specifically,
/* struct bpf_insn: _s32 imm */
u64 imm = insn->imm; /* sign extend */
if (imm >> 32) { /* non-zero only if insn->imm is negative */
/* inlined from ur_load_imm_any */
u32 __imm = imm >> 32; /* therefore, always 0xffffffff */
if (__builtin_constant_p(__imm) && __imm > 255)
compiletime_assert_XXX()
This can result in tripping a BUILD_BUG_ON() in __BF_FIELD_CHECK() that
checks that a given value is representable in one byte (interpreted as
unsigned).
FIELD_FIT() should return true or false at runtime for whether a value
can fit for not. Don't break the build over a value that's too large for
the mask. We'd prefer to keep the inlining and compiler optimizations
though we know this case will always return false.

When TFO keys are read back on big endian systems either via the global
sysctl interface or via getsockopt() using TCP_FASTOPEN_KEY, the values
don't match what was written.
For example, on s390x:
# echo "1-2-3-4" > /proc/sys/net/ipv4/tcp_fastopen_key
# cat /proc/sys/net/ipv4/tcp_fastopen_key
02000000-01000000-04000000-03000000
Instead of:
# cat /proc/sys/net/ipv4/tcp_fastopen_key
00000001-00000002-00000003-00000004
Fix this by converting to the correct endianness on read. This was
reported by Colin Ian King when running the 'tcp_fastopen_backup_key' net
selftest on s390x, which depends on the read value matching what was
written. I've confirmed that the test now passes on big and little endian
systems.

Trying to use ktls on a system with 32-bit userspace and 64-bit kernel

setsockopt(3, SOL_TLS, TLS_TX, …, 40) = 0
sendmsg(3, …, msg_flags=0}, 0) = -1 EOPNOTSUPP (Operation not supported)
The tls_sw implementation does strict flag checking and does not allow
the MSG_CMSG_COMPAT flag, which is set if the message comes in through
the compat syscall.
This patch adds MSG_CMSG_COMPAT to the flag check to allow the usage of
the TLS SW implementation on systems using the compat syscall path.
Note that the same check is present in the sendmsg path for the TLS
device implementation, however the flag hasn't been added there for lack

dump.
Such wait is introduced after shutting down one sockets end. Since
commit 43b54c6ee3 ("mptcp: Use full MPTCP-level disconnect state

into CLOSED status.
As a side effect some sockets are not dumped via the diag interface,
because the socket state (CLOSED) does not match the default filter, and
this cause self-tests instability.
Address the issue moving the above mentioned wait before shutting

The struct device embedded into the struct net_device does not have a

1. Added a skb->len check
This driver expects upper layers to include a pseudo header of 1 byte
when passing down a skb for transmission. This driver will read this
1-byte header. This patch added a skb->len check before reading the
header to make sure the header exists.
2. Changed to use needed_headroom instead of hard_header_len to request
necessary headroom to be allocated
In net/packet/af_packet.c, the function packet_snd first reserves a
headroom of length (dev->hard_header_len + dev->needed_headroom).
Then if the socket is a SOCK_DGRAM socket, it calls dev_hard_header,
which calls dev->header_ops->create, to create the link layer header.
If the socket is a SOCK_RAW socket, it "un-reserves" a headroom of
length (dev->hard_header_len), and assumes the user to provide the
appropriate link layer header.
So according to the logic of af_packet.c, dev->hard_header_len should
be the length of the header that would be created by
dev->header_ops->create.
However, this driver doesn't provide dev->header_ops, so logically
dev->hard_header_len should be 0.
So we should use dev->needed_headroom instead of dev->hard_header_len
to request necessary headroom to be allocated.
This change fixes kernel panic when this driver is used with AF_PACKET
SOCK_RAW sockets.

Yonghong Song says:
====================
Andrii raised a concern that current uapi for bpf iterator map
element is a little restrictive and not suitable for future potential
complex customization. This is a valid suggestion, considering people
may indeed add more complex custimization to the iterator, e.g.,
cgroup_id + user_id, etc. for task or task_file. Another example might
be map_id plus additional control so that the bpf iterator may bail
out a bucket earlier if a bucket has too many elements which may hold
lock too long and impact other parts of systems.
Patch #1 modified uapi with kernel changes. Patch #2
adjusted libbpf api accordingly.
Changelogs:
v3 -> v4:
. add a forward declaration of bpf_iter_link_info in
tools/lib/bpf/bpf.h in case that libbpf is built against
not-latest uapi bpf.h.
. target the patch set to "bpf" instead of "bpf-next"
v2 -> v3:
. undo "not reject iter_info.map.map_fd == 0" from v1.
In the future map_fd may become optional, so let us use map_fd == 0
indicating the map_fd is not set by user space.
. add link_info_len to bpf_iter_attach_opts to ensure always correct
link_info_len from user. Otherwise, libbpf may deduce incorrect
link_info_len if it uses different uapi header than the user app.
v1 -> v2:
. ensure link_create target_fd/flags == 0 since they are not used. (Andrii)
. if either of iter_info ptr == 0 or iter_info_len == 0, but not both,
return error to user space. (Andrii)
. do not reject iter_info.map.map_fd == 0, go ahead to use it trying to
get a map reference since the map_fd is required for map_elem iterator.
. use bpf_iter_link_info in bpf_iter_attach_opts instead of map_fd.
this way, user space is responsible to set up bpf_iter_link_info and
libbpf just passes the data to the kernel, simplifying libbpf design.

Commit a5cbe05a66 ("bpf: Implement bpf iterator for
map elements") added bpf iterator support for
map elements. The map element bpf iterator requires
info to identify a particular map. In the above
commit, the attr->link_create.target_fd is used
to carry map_fd and an enum bpf_iter_link_info
is added to uapi to specify the target_fd actually
representing a map_fd:
enum bpf_iter_link_info {
BPF_ITER_LINK_UNSPEC = 0,
BPF_ITER_LINK_MAP_FD = 1,
MAX_BPF_ITER_LINK_INFO,
};
This is an extensible approach as we can grow
enumerator for pid, cgroup_id, etc. and we can
unionize target_fd for pid, cgroup_id, etc.
But in the future, there are chances that
more complex customization may happen, e.g.,
for tasks, it could be filtered based on
both cgroup_id and user_id.
This patch changed the uapi to have fields
__aligned_u64 iter_info;
__u32 iter_info_len;
for additional iter_info for link_create.
The iter_info is defined as
union bpf_iter_link_info {
struct {
__u32 map_fd;
} map;
};
So future extension for additional customization
will be easier. The bpf_iter_link_info will be
passed to target callback to validate and generic
bpf_iter framework does not need to deal it any
more.
Note that map_fd = 0 will be considered invalid
and -EBADF will be returned to user space.

this means that often when building selftests from scratch (after `make

"New xilinx displayport driver, AMD support for two new GPUs (more
header files), i915 initial support for RocketLake and some work on
their DG1 (discrete chip).
The core also grew some lockdep annotations to try and constrain what
drivers do with dma-fences, and added some documentation on why the
idea of indefinite fences doesn't work.

Okay, so... this one is interesting. RGB LEDs are very common, and we
need to have some kind of support for them. Multicolor is for
arbitrary set of LEDs in one package, RGB is for LEDs that can produce
full range of colors. We do not have real multicolor LED that is not
RGB in the pipeline, so that one is disabled for now.
You can expect this saga to continue with next pull requests.

====================
misc bug fixes for the hso driver
1. Code reuse led to an unregistration of a net driver that has not been
registered
2. The kernel complains generically if kmalloc with GFP_KERNEL fails
3. A race that can lead to an URB that is in use being reused or
a use after free
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This check an inherent race. It opens a race where
an error code has already been set or cleared yet
the URB has not been given back. We cannot do
such an optimization and must unlink unconditionally.

If this fails, kmalloc() will print a report including
a stack trace. There is no need for a separate complaint.

The driver tries to reuse code for disconnect in case
of a failed probe.
If resources need to be freed after an error in probe, the
netdev must not be freed because it has never been registered.
Fix it by telling the helper which path we are in.

Before switch from discontigmem to sparsemem, there always was
CONFIG_NEED_MULTIPLE_NODES=y because it was selected by DISCONTIGMEM.
Without DISCONTIGMEM it is possible to have SPARSEMEM without NUMA for
SGI_IP27 and as many things there rely on custom node definition, the
build breaks.
As Thomas noted "... there are right now too many places in IP27 code,
which assumes NUMA enabled", the simplest solution would be to always
enable NUMA for SGI-IP27 builds.

This series adds reporting of the page table order from hmm_range_fault()
and some optimization of migrate_vma():
- Report the size of the page table mapping out of hmm_range_fault(). This
makes it easier to establish a large/huge/etc mapping in the device's
page table.
- Allow devices to ignore the invalidations during migration in cases
where the migration is not going to change pages. For instance migrating
pages to a device does not require the device to invalidate pages
already in the device.
- Update nouveau and hmm_tests to use the above
