Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument
This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org> |

rds: tcp: fix uninit-value in __inet_bind
KMSAN reported an uninit-value access in __inet_bind() when binding
an RDS TCP socket.
The uninitialized memory originates from rds_tcp_conn_alloc(),
which uses kmem_cache_alloc() to allocate the rds_tcp_connection structure.
Specifically, the field 't_client_port_group' is incremented in
rds_tcp_conn_path_connect() without being initialized first:
if (++tc->t_client_port_group >= port_groups)
Since kmem_cache_alloc() does not zero the memory, this field contains
garbage, leading to the KMSAN report.
Fix this by using kmem_cache_zalloc() to ensure the structure is
zero-initialized upon allocation.

net/rds: Fix NULL pointer dereference in rds_tcp_accept_one
Save a local pointer to new_sock->sk and hold a reference before
installing callbacks in rds_tcp_accept_one. After
rds_tcp_set_callbacks() or rds_tcp_reset_callbacks(), tc->t_sock is
set to new_sock which may race with the shutdown path. A concurrent
rds_tcp_conn_path_shutdown() may call sock_release(), which sets
new_sock->sk = NULL and may eventually free sk when the refcount
reaches zero.
Subsequent accesses to new_sock->sk->sk_state would dereference NULL,
causing the crash. The fix saves a local sk pointer before callbacks
are installed so that sk_state can be accessed safely even after
new_sock->sk is nulled, and uses sock_hold()/sock_put() to ensure
sk itself remains valid for the duration.

ipv6: icmp: remove obsolete code in icmpv6_xrlim_allow()
Following part was needed before the blamed commit, because
inet_getpeer_v6() second argument was the prefix.
/* Give more bandwidth to wider prefixes. */
if (rt->rt6i_dst.plen < 128)
tmo >>= ((128 - rt->rt6i_dst.plen)>>5);
Now inet_getpeer_v6() retrieves hosts, we need to remove
@tmo adjustement or wider prefixes likes /24 allow 8x
more ICMP to be sent for a given ratelimit.
As we had this issue for a while, this patch changes net.ipv6.icmp.ratelimit
default value from 1000ms to 100ms to avoid potential regressions.
Also add a READ_ONCE() when reading net->ipv6.sysctl.icmpv6_time.

netfilter: nf_tables: fix use-after-free in nf_tables_addchain()
nf_tables_addchain() publishes the chain to table->chains via
list_add_tail_rcu() (in nft_chain_add()) before registering hooks.
If nf_tables_register_hook() then fails, the error path calls
nft_chain_del() (list_del_rcu()) followed by nf_tables_chain_destroy()
with no RCU grace period in between.
This creates two use-after-free conditions:
1) Control-plane: nf_tables_dump_chains() traverses table->chains
under rcu_read_lock(). A concurrent dump can still be walking
the chain when the error path frees it.
2) Packet path: for NFPROTO_INET, nf_register_net_hook() briefly
installs the IPv4 hook before IPv6 registration fails. Packets
entering nft_do_chain() via the transient IPv4 hook can still be
dereferencing chain->blob_gen_X when the error path frees the
chain.
Add synchronize_rcu() between nft_chain_del() and the chain destroy
so that all RCU readers -- both dump threads and in-flight packet
evaluation -- have finished before the chain is freed.

ipvs: do not keep dest_dst if dev is going down
There is race between the netdev notifier ip_vs_dst_event()
and the code that caches dst with dev that is going down.
As the FIB can be notified for the closed device after our
handler finishes, it is possible valid route to be returned
and cached resuling in a leaked dev reference until the dest
is not removed.
To prevent new dest_dst to be attached to dest just after the
handler dropped the old one, add a netif_running() check
to make sure the notifier handler is not currently running
for device that is closing.

Add a global static spinlock to serialize counter fetch+reset operations, preventing concurrent dump-and-reset from underrunning values.

A global lock is used for simplicity since resets are infrequent. If this becomes a bottleneck, it can be replaced with a per-net lock later. Fixes: |

netfilter: annotate NAT helper hook pointers with __rcu
The NAT helper hook pointers are updated and dereferenced under RCU rules, but lack the proper __rcu annotation.

net: bridge: mcast: always update mdb_n_entries for vlan contexts
syzbot triggered a warning[1] about the number of mdb entries in a context.
It turned out that there are multiple ways to trigger that warning today
(some got added during the years), the root cause of the problem is that
the increase is done conditionally, and over the years these different
conditions increased so there were new ways to trigger the warning, that is
to do a decrease which wasn't paired with a previous increase.
For example one way to trigger it is with flush:
$ ip l add br0 up type bridge vlan_filtering 1 mcast_snooping 1
$ ip l add dumdum up master br0 type dummy
$ bridge mdb add dev br0 port dumdum grp 239.0.0.1 permanent vid 1
$ ip link set dev br0 down
$ ip link set dev br0 type bridge mcast_vlan_snooping 1
^^^^ this will enable snooping, but will not update mdb_n_entries
because in __br_multicast_enable_port_ctx() we check !netif_running
$ bridge mdb flush dev br0
^^^ this will trigger the warning because it will delete the pg which
we added above, which will try to decrease mdb_n_entries
Fix the problem by removing the conditional increase and always keep the
count up-to-date while the vlan exists. In order to do that we have to
first initialize it on port-vlan context creation, and then always increase
or decrease the value regardless of mcast options. To keep the current
behaviour we have to enforce the mdb limit only if the context is port's or
if the port-vlan's mcast snooping is enabled.

vsock: prevent child netns mode switch from local to global
A "local" namespace can change its `child_ns_mode` sysctl to "global",
allowing nested namespaces to access global CIDs. This can be exploited
by an unprivileged user who gained CAP_NET_ADMIN through a user
namespace.
Prevent this by rejecting writes that attempt to set `child_ns_mode` to
"global" when the current namespace's mode is "local".

vsock: fix child netns mode initialization
When a new network namespace is created, vsock_net_init() correctly
initializes the namespace's mode by reading the parent's `child_ns_mode`
via vsock_net_child_mode(). However, the `child_ns_mode` of the new
namespace was always hardcoded to VSOCK_NET_MODE_GLOBAL, regardless of
its own mode.
This means that if a parent namespace has `child_ns_mode` set to "local",
the child namespace correctly gets mode "local", but its `child_ns_mode`
is reset to "global". As a result, further nested namespaces will
incorrectly get mode "global" instead of inheriting "local", breaking
the expected propagation of the mode through nested namespaces.
Fix this by initializing `child_ns_mode` to the namespace's own mode,
so the setting propagates correctly through all levels of nesting.

ipv6: Fix out-of-bound access in fib6_add_rt2node().
syzbot reported out-of-bound read in fib6_add_rt2node(). [0]
When IPv6 route is created with RTA_NH_ID, struct fib6_info
does not have the trailing struct fib6_nh.
The cited commit started to check !iter->fib6_nh->fib_nh_gw_family
to ensure that rt6_qualify_for_ecmp() will return false for iter.
If iter->nh is not NULL, rt6_qualify_for_ecmp() returns false anyway.
Let's check iter->nh before reading iter->fib6_nh and avoid OOB read.

ipv6: ioam: fix heap buffer overflow in __ioam6_fill_trace_data()
On the receive path, __ioam6_fill_trace_data() uses trace->nodelen
to decide how much data to write for each node. It trusts this field
as-is from the incoming packet, with no consistency check against
trace->type (the 24-bit field that tells which data items are
present). A crafted packet can set nodelen=0 while setting type bits
0-21, causing the function to write ~100 bytes past the allocated
region (into skb_shared_info), which corrupts adjacent heap memory
and leads to a kernel panic.
Add a shared helper ioam6_trace_compute_nodelen() in ioam6.c to
derive the expected nodelen from the type field, and use it:
- in ioam6_iptunnel.c (send path, existing validation) to replace
the open-coded computation;
- in exthdrs.c (receive path, ipv6_hop_ioam) to drop packets whose
nodelen is inconsistent with the type field, before any data is
written.
Per RFC 9197, bits 12-21 are each short (4-octet) fields, so they
are included in IOAM6_MASK_SHORT_FIELDS (changed from 0xff100000 to
0xff1ffc00).

NFSD 7.0 Release Notes
Neil Brown and Jeff Layton contributed a dynamic thread pool sizing mechanism for NFSD. The sunrpc layer now tracks minimum and maximum thread counts per pool, and NFSD adjusts running thread counts based on workload: idle threads exit after a timeout when the pool exceeds its minimum, and new threads spawn automatically when all threads are busy. Administrators control this behavior via the nfsdctl netlink interface. Rick Macklem, FreeBSD NFS maintainer, generously contributed server- side support for the POSIX ACL extension to NFSv4, as specified in draft-ietf-nfsv4-posix-acls. This extension allows NFSv4 clients to get and set POSIX access and default ACLs using native NFSv4 operations, eliminating the need for sideband protocols. The feature is gated by a Kconfig option since the IETF draft has not yet been ratified. Chuck Lever delivered numerous improvements to the xdrgen tool. Error reporting now covers parsing, AST transformation, and invalid declarations. Generated enum decoders validate incoming values against valid enumerator lists. New features include pass-through line support for embedding C directives in XDR specifications, 16-bit integer types, and program number definitions. Several code generation issues were also addressed. When an administrator revokes NFSv4 state for a filesystem via the unlock_fs interface, ongoing async COPY operations referencing that filesystem are now cancelled, with CB_OFFLOAD callbacks notifying affected clients. The remaining patches in this pull request are clean-ups and minor optimizations. Sincere thanks to all contributors, reviewers, testers, and bug reporters who participated in the v7.0 NFSD development cycle. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmmJ8kAACgkQM2qzM29m f5ejCQ//RdoWNgN1VZdNoUrh1tm1Fhi1YN/RJS26G25OxgTBc3/qtGxrpW+ZAW6+ mIAJ2bT/l66741drki4/x6WJU4OMI/4mJxrLd0WCb1POaeRQWnL1MdzNY+IP/QZv 3DgcTv1T6FKE7pFmAqW0nFPCgaK+vlR+fo4uJognbB6+hZB3HlrLkfeZOWMAmchC y3U6nzrtP+IljAtdzKZ120E+LHp0PtTbJwPCPSt3/FR/dkA0DcjnOS9jybIYlJOu 0ByX24BcrW/c3rJUdL8lL4G7gsPWjdARqczFiN8sufI9Q3zlHOxtYdUT7BNjd+04 jcSKLlAXwcbNcK2f54B/QFKmNxllvoHLB3wo2hfEPig4LQELuxcUHYxmmD4vNKen lp6zmaLq3PiRGlew6eLRFxRxbdLds+9l0xjXV+J+rtQmjppXdXUoVNMm+D+tD6bF T5TUq4WNCGJIrpkR7pdF7uMD51s8fphvaDxOCjhSi3WHAtZAhOR8HFUU97qddM34 KqF6Gph3tN/C4oNb8kKvzxBRpRhHIzKHZbreiu5fZr9pPe9IRBHnn/Dg4p/yYQcw K3/y1EnKrIlprfbFFkY1LzNFpf309uoZTVzwBcMfSJVsFgUqWD7KHJ/rmCJQ/pS6 k0+YLRoUmtUHDYk2QNlstlt7r6FwA0d2GjT8n7viGoNQ3PA7rJQ= =hqla -----END PGP SIGNATURE----- Merge tag 'nfsd-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "Neil Brown and Jeff Layton contributed a dynamic thread pool sizing mechanism for NFSD.

Networking changes for 7.0
Core & protocols
----------------
- A significant effort all around the stack to guide the compiler to
make the right choice when inlining code, to avoid unneeded calls for
small helper and stack canary overhead in the fast-path. This
generates better and faster code with very small or no text size
increases, as in many cases the call generated more code than the
actual inlined helper.
- Extend AccECN implementation so that is now functionally complete,
also allow the user-space enabling it on a per network namespace
basis.
- Add support for memory providers with large (above 4K) rx buffer.
Paired with hw-gro, larger rx buffer sizes reduce the number of
buffers traversing the stack, dincreasing single stream CPU usage by
up to ~30%.
- Do not add HBH header to Big TCP GSO packets. This simplifies the RX
path, the TX path and the NIC drivers, and is possible because
user-space taps can now interpret correctly such packets without the
HBH hint.
- Allow IPv6 routes to be configured with a gateway address that is
resolved out of a different interface than the one specified, aligning
IPv6 to IPv4 behavior.
- Multi-queue aware sch_cake. This makes it possible to scale the rate
shaper of sch_cake across multiple CPUs, while still enforcing a
single global rate on the interface.
- Add support for the nbcon (new buffer console) infrastructure to
netconsole, enabling lock-free, priority-based console operations that
are safer in crash scenarios.
- Improve the TCP ipv6 output path to cache the flow information, saving
cpu cycles, reducing cache line misses and stack use.
- Improve netfilter packet tracker to resolve clashes for most protocols,
avoiding unneeded drops on rare occasions.
- Add IP6IP6 tunneling acceleration to the flowtable infrastructure.
- Reduce tcp socket size by one cache line.
- Notify neighbour changes atomically, avoiding inconsistencies between
the notification sequence and the actual states sequence.
- Add vsock namespace support, allowing complete isolation of vsocks
across different network namespaces.
- Improve xsk generic performances with cache-alignment-oriented
optimizations.
- Support netconsole automatic target recovery, allowing netconsole
to reestablish targets when underlying low-level interface comes back
online.
Driver API
----------
- Support for switching the working mode (automatic vs manual) of a DPLL
device via netlink.
- Introduce PHY ports representation to expose multiple front-facing
media ports over a single MAC.
- Introduce "rx-polarity" and "tx-polarity" device tree properties, to
generalize polarity inversion requirements for differential signaling.
- Add helper to create, prepare and enable managed clocks.
Device drivers
--------------
- Add Huawei hinic3 PF etherner driver.
- Add DWMAC glue driver for Motorcomm YT6801 PCIe ethernet controller.
