[ Upstream commit 523b84dc7ccea9c4d79126d6ed1cf9033cf83b05 ]
The current implementation may lead to buffer overflow when:
1. Unregistration creates NULL gaps in registered_fb[]
2. All array slots become occupied despite num_registered_fb < FB_MAX
3. The registration loop exceeds array bounds
Add boundary check to prevent registered_fb[FB_MAX] access.

[ Upstream commit 33cfdd726381828b9907a61c038a9f48b6690a31 ]
Some servers might enforce the SPN to be set in the target info
blob (AV pairs) when sending NTLMSSP_AUTH message. In Windows Server,
this could be enforced with SmbServerNameHardeningLevel set to 2.
Fix this by always appending SPN (cifs/<hostname>) to the existing
list of target infos when setting up NTLMv2 response blob.

[ Upstream commit b460249b9a1dab7a9f58483e5349d045ad6d585c ]
To query root path (without msearch wildcard) it is needed to
send pattern '\' instead of '' (empty string).
This allows to use CIFSFindFirst() to query information about root path
which is being used in followup changes.
This change fixes the stat() syscall called on the root path on the mount.
It is because stat() syscall uses the cifs_query_path_info() function and
it can fallback to the CIFSFindFirst() usage with msearch=false.

[ Upstream commit 48defdf6b083f74a44e1f742db284960d3444aec ]
The MediaTek implementation of the sbsa_gwdt watchdog has a race
condition where a write to SBSA_GWDT_WRR is ignored if it occurs while
the hardware is processing a timeout refresh that asserts WS0.
Detect this based on the hardware implementer and adjust
wdd->min_hw_heartbeat_ms to avoid the race by forcing the keepalive ping
to be one second later.

[ Upstream commit 03a92f036a04fed2b00d69f5f46f1a486e70dc5c ]
When allocating receive buffers for the vsock virtio RX virtqueue, an
SKB is allocated with a 4140 data payload (the 44-byte packet header +
VIRTIO_VSOCK_DEFAULT_RX_BUF_SIZE). Even when factoring in the SKB
overhead, the resulting 8KiB allocation thanks to the rounding in
kmalloc_reserve() is wasteful (~3700 unusable bytes) and results in a
higher-order page allocation on systems with 4KiB pages just for the
sake of a few hundred bytes of packet data.
Limit the vsock virtio RX buffers to 4KiB per SKB, resulting in much
better memory utilisation and removing the need to allocate higher-order
pages entirely.

[ Upstream commit b41642c87716bbd09797b1e4ea7d904f06c39b7b ]
During rcu_read_unlock_special(), if this happens during irq_exit(), we
can lockup if an IPI is issued. This is because the IPI itself triggers
the irq_exit() path causing a recursive lock up.
This is precisely what Xiongfeng found when invoking a BPF program on
the trace_tick_stop() tracepoint As shown in the trace below. Fix by
managing the irq_work state correctly.
irq_exit()
__irq_exit_rcu()
/* in_hardirq() returns false after this */
preempt_count_sub(HARDIRQ_OFFSET)
tick_irq_exit()
tick_nohz_irq_exit()
tick_nohz_stop_sched_tick()
trace_tick_stop() /* a bpf prog is hooked on this trace point */
__bpf_trace_tick_stop()
bpf_trace_run2()
rcu_read_unlock_special()
/* will send a IPI to itself */
irq_work_queue_on(&rdp->defer_qs_iw, rdp->cpu);
A simple reproducer can also be obtained by doing the following in
tick_irq_exit(). It will hang on boot without the patch:
static inline void tick_irq_exit(void)
{
+ rcu_read_lock();
+ WRITE_ONCE(current->rcu_read_unlock_special.b.need_qs, true);

[ Upstream commit eac21f8ebeb4f84d703cf41dc3f81d16fa9dc00a ]
Currently the TTM shrinker aborts shrinking as soon as it frees pages from
any of the page order pools and by doing so it can fail to respect the
freeing target which was configured by the shrinker core.
We use the wording "can fail" because the number of freed pages will
depend on the presence of pages in the pools and the order of the pools on
the LRU list. For example if there are no free pages in the high order
pools the shrinker core may require multiple passes over the TTM shrinker
before it will free the default target of 128 pages (assuming there are
free pages in the low order pools). This inefficiency can be compounded by
the pool LRU where multiple further calls into the TTM shrinker are
required to end up looking at the pool with pages.
Improve this by never freeing less than the shrinker core has requested.
At the same time we start reporting the number of scanned pages (freed in
this case), which prevents the core shrinker from giving up on the TTM
shrinker too soon and moving on.
v2:
* Simplify loop logic. (Christian)
* Improve commit message.

[ Upstream commit 5534e58f2e9bd72b253d033ee0af6e68eb8ac96b ]
When reg->type is CONST_PTR_TO_MAP, it can not be null. However the
verifier explores the branches under rX == 0 in check_cond_jmp_op()
even if reg->type is CONST_PTR_TO_MAP, because it was not checked for
in reg_not_null().
Fix this by adding CONST_PTR_TO_MAP to the set of types that are
considered non nullable in reg_not_null().
An old "unpriv: cmp map pointer with zero" selftest fails with this
change, because now early out correctly triggers in
check_cond_jmp_op(), making the verification to pass.
In practice verifier may allow pointer to null comparison in unpriv,
since in many cases the relevant branch and comparison op are removed
as dead code. So change the expected test result to __success_unpriv.

[ Upstream commit 31557b3487b349464daf42bc4366153743c1e727 ]
A decade ago commit 6d08acd2d32e ("in6: fix conflict with glibc")
hid the definitions of IPV6 options, because GCC was complaining
about duplicates. The commit did not list the warnings seen, but
trying to recreate them now I think they are (building iproute2):
In file included from ./include/uapi/rdma/rdma_user_cm.h:39,
from rdma.h:16,
from res.h:9,
from res-ctx.c:7:
../include/uapi/linux/in6.h:171:9: warning: ‘IPV6_ADD_MEMBERSHIP’ redefined
171 | #define IPV6_ADD_MEMBERSHIP 20
| ^~~~~~~~~~~~~~~~~~~
In file included from /usr/include/netinet/in.h:37,
from rdma.h:13:
/usr/include/bits/in.h:233:10: note: this is the location of the previous definition
233 | # define IPV6_ADD_MEMBERSHIP IPV6_JOIN_GROUP
| ^~~~~~~~~~~~~~~~~~~
../include/uapi/linux/in6.h:172:9: warning: ‘IPV6_DROP_MEMBERSHIP’ redefined
172 | #define IPV6_DROP_MEMBERSHIP 21
| ^~~~~~~~~~~~~~~~~~~~
/usr/include/bits/in.h:234:10: note: this is the location of the previous definition
234 | # define IPV6_DROP_MEMBERSHIP IPV6_LEAVE_GROUP
| ^~~~~~~~~~~~~~~~~~~~
Compilers don't complain about redefinition if the defines
are identical, but here we have the kernel using the literal
value, and glibc using an indirection (defining to a name
of another define, with the same numerical value).
Problem is, the commit in question hid all the IPV6 socket
options, and glibc has a pretty sparse list. For instance
it lacks Flow Label related options. Willem called this out
in commit 3fb321fde22d ("selftests/net: ipv6 flowlabel"):
/* uapi/glibc weirdness may leave this undefined */
#ifndef IPV6_FLOWINFO
#define IPV6_FLOWINFO 11
#endif
More interestingly some applications (socat) use
a #ifdef IPV6_FLOWINFO to gate compilation of thier
rudimentary flow label support. (For added confusion
socat misspells it as IPV4_FLOWINFO in some places.)
Hide only the two defines we know glibc has a problem
with. If we discover more warnings we can hide more
but we should avoid covering the entire block of
defines for "IPV6 socket options".

[ Upstream commit 6bd90e700b4285e6a7541e00f969cab0d696adde ]
Xe can free some of the data pointed to by the dma-fences it exports. Most
notably the timeline name can get freed if userspace closes the associated
submit queue. At the same time the fence could have been exported to a
third party (for example a sync_fence fd) which will then cause an use-
after-free on subsequent access.
To make this safe we need to make the driver compliant with the newly
documented dma-fence rules. Driver has to ensure a RCU grace period
between signalling a fence and freeing any data pointed to by said fence.
For the timeline name we simply make the queue be freed via kfree_rcu and
for the shared lock associated with multiple queues we add a RCU grace
period before freeing the per GT structure holding the lock.

[ Upstream commit 966a83df36c6f27476ac3501771422e7852098bc ]
According to the datasheet, BCM5325 uses B53_PD_MODE_CTRL_25 register to
disable clocking to individual PHYs.
Only ports 1-4 can be enabled or disabled and the datasheet is explicit
about not toggling BIT(0) since it disables the PLL power and the switch.

In gve_adminq_issue_cmd(), return -EINVAL instead of 0 when an unknown
admin queue command opcode is encountered.
This prevents the function from silently succeeding on invalid input
and prevents undefined behavior by ensuring the function fails gracefully
when an unrecognized opcode is provided.

When CONFIG_VLAN_8021Q=n, a set of stub helpers are used, three of these
helpers use BUG() unconditionally.
This code should not be reached, as callers of these functions should
always check for is_vlan_dev() first, but the usage of BUG() is not
recommended, replace it with WARN_ON() instead.

[ Upstream commit 2de1ba0887e5d3bf02d7c212f380039b34e10aa3 ]
Add a stub implementation of is_vlan_dev() that returns false when
VLAN support is not compiled in (CONFIG_VLAN_8021Q=n).
This allows us to compile-out VLAN-dependent dead code when it is not
needed.
This also resolves the following compilation error when:
* CONFIG_VLAN_8021Q=n
* CONFIG_OBJTOOL=y
* CONFIG_OBJTOOL_WERROR=y
drivers/net/ethernet/mellanox/mlx5/core/mlx5_core.o: error: objtool: parse_mirred.isra.0+0x370: mlx5e_tc_act_vlan_add_push_action() missing __noreturn in .c/.h or NORETURN() in noreturns.h
The error occurs because objtool cannot determine that unreachable BUG()
(which doesn't return) calls in VLAN code paths are actually dead code
when VLAN support is disabled.

[ Upstream commit 140c6a61d83cbd85adba769b5ef8d61acfa5b392 ]
Currently, when a non-DFS channel is brought up and the bandwidth is
expanded from 80 MHz to 160 MHz, where the primary 80 MHz is non-DFS
and the secondary 80 MHz consists of DFS channels, radar detection
fails if radar occurs in the secondary 80 MHz.
When the channel is switched from 80 MHz to 160 MHz, with the primary
80 MHz being non-DFS and the secondary 80 MHz consisting of DFS
channels, the radar required flag in the channel switch parameters
is set to true. However, when using a reserved channel context,
it is not updated in sdata, which disables radar detection in the
secondary 80 MHz DFS channels.
Update the radar required flag in sdata to fix this issue when using
a reserved channel context.
