net: microchip: vcap api: Fix possible memory leak for vcap_dup_rule()
Inject fault When select CONFIG_VCAP_KUNIT_TEST, the below memory leak
occurs. If kzalloc() for duprule succeeds, but the following
kmemdup() fails, the duprule, ckf and caf memory will be leaked. So kfree
them in the error path.

net: bcmasp: add missing of_node_put
for_each_available_child_of_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put.

selftests/net: Improve bind_bhash.sh to accommodate predictable network interface names
Starting with v197, systemd uses predictable interface network names, the traditional interface naming scheme (eth0) is deprecated, therefore it cannot be assumed that the eth0 interface exists on the host. This modification makes the bind_bhash test program run in a separate network namespace and no longer needs to consider the name of the network interface on the host.

net: ipv4: fix one memleak in __inet_del_ifa()
I got the below warning when do fuzzing test:
unregister_netdevice: waiting for bond0 to become free. Usage count = 2
It can be repoduced via:
ip link add bond0 type bond
sysctl -w net.ipv4.conf.bond0.promote_secondaries=1
ip addr add 4.117.174.103/0 scope 0x40 dev bond0
ip addr add 192.168.100.111/255.255.255.254 scope 0 dev bond0
ip addr add 0.0.0.4/0 scope 0x40 secondary dev bond0
ip addr del 4.117.174.103/0 scope 0x40 dev bond0
ip link delete bond0 type bond
In this reproduction test case, an incorrect 'last_prim' is found in
__inet_del_ifa(), as a result, the secondary address(0.0.0.4/0 scope 0x40)
is lost. The memory of the secondary address is leaked and the reference of
in_device and net_device is leaked.
Fix this problem:
Look for 'last_prim' starting at location of the deleted IP and inserting
the promoted IP into the location of 'last_prim'.

spi: Fixes for v6.6
A couple of fixes for the sun6i driver, the patch to reduce DMA RX to single byte width all the time is *hopefully* excessively cautious but it's unclear which SoCs are affected so the fix just covers everything for safety. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmT5wQ0ACgkQJNaLcl1U h9Bltgf/T7tViGF1+g0fUx7Nlju+h8Hg3qBhlE+VKwRO6/qjBczT4ny4nkiej+CK IapuEDul+F56Cy4/dgyFQkICTCm7qGev+r7Oya0OCWqAiXif5fz/zfxc4rHUzRA9 lZrdWrYNxhlAqcDu80G00nh5Gx5UCpTHEriWJQUQ0oxXGQoPRPW2WczMsksF6QLs gnqr7hhIWzSvj0OOHVWi6a1iOMVgw0ICEgUF6TSoDsMOzvi6c1WVnCLZaE6udWhv 0wwOBzH1YBbwhfK/RdjUcSfHIy/jI2Gs7BnrUWviIfQSCb90V9YvAGlgusJAR4Ks Y5UM3d8pVxQg5tW75IFjMt/fic6Rfg== =HZqv -----END PGP SIGNATURE----- Merge tag 'spi-fix-v6.6-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi fixes from Mark Brown: "A couple of fixes for the sun6i driver.

ARM:
* Clean up vCPU targets, always returning generic v8 as the preferred target
* Trap forwarding infrastructure for nested virtualization (used for traps
that are taken from an L2 guest and are needed by the L1 hypervisor)
* FEAT_TLBIRANGE support to only invalidate specific ranges of addresses
when collapsing a table PTE to a block PTE. This avoids that the guest
refills the TLBs again for addresses that aren't covered by the table PTE.
* Fix vPMU issues related to handling of PMUver.
* Don't unnecessary align non-stack allocations in the EL2 VA space
* Drop HCR_VIRT_EXCP_MASK, which was never used...
* Don't use smp_processor_id() in kvm_arch_vcpu_load(),
but the cpu parameter instead
* Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort()
* Remove prototypes without implementations
RISC-V:
* Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for guest
* Added ONE_REG interface for SATP mode
* Added ONE_REG interface to enable/disable multiple ISA extensions
* Improved error codes returned by ONE_REG interfaces
* Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V
* Added get-reg-list selftest for KVM RISC-V
s390:
* PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)
Allows a PV guest to use crypto cards. Card access is governed by
the firmware and once a crypto queue is "bound" to a PV VM every
other entity (PV or not) looses access until it is not bound
anymore. Enablement is done via flags when creating the PV VM.
* Guest debug fixes (Ilya)
x86:
* Clean up KVM's handling of Intel architectural events
* Intel bugfixes
* Add support for SEV-ES DebugSwap, allowing SEV-ES guests to use debug
registers and generate/handle #DBs
* Clean up LBR virtualization code
* Fix a bug where KVM fails to set the target pCPU during an IRTE update
* Fix fatal bugs in SEV-ES intrahost migration
* Fix a bug where the recent (architecturally correct) change to reinject
#BP and skip INT3 broke SEV guests (can't decode INT3 to skip it)
* Retry APIC map recalculation if a vCPU is added/enabled
* Overhaul emergency reboot code to bring SVM up to par with VMX, tie the
"emergency disabling" behavior to KVM actually being loaded, and move all of
the logic within KVM
* Fix user triggerable WARNs in SVM where KVM incorrectly assumes the TSC
ratio MSR cannot diverge from the default when TSC scaling is disabled
up related code
* Add a framework to allow "caching" feature flags so that KVM can check if
the guest can use a feature without needing to search guest CPUID
* Rip out the ancient MMU_DEBUG crud and replace the useful bits with
CONFIG_KVM_PROVE_MMU
* Fix KVM's handling of !visible guest roots to avoid premature triple fault
injection
* Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the API surface
that is needed by external users (currently only KVMGT), and fix a variety
of issues in the process
This last item had a silly one-character bug in the topic branch that
was sent to me. Because it caused pretty bad selftest failures in
some configurations, I decided to squash in the fix. So, while the
exact commit ids haven't been in linux-next, the code has (from the
kvm-x86 tree).
Generic:
* Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier events to pass
action specific data without needing to constantly update the main handlers.
* Drop unused function declarations
Selftests:
* Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs
* Add support for printf() in guest code and covert all guest asserts to use
printf-based reporting
* Clean up the PMU event filter test and add new testcases
* Include x86 selftests in the KVM x86 MAINTAINERS entry

net: enetc: distinguish error from valid pointers in enetc_fixup_clear_rss_rfs()
enetc_psi_create() returns an ERR_PTR() or a valid station interface
pointer, but checking for the non-NULL quality of the return code blurs
that difference away. So if enetc_psi_create() fails, we call
enetc_psi_destroy() when we shouldn't. This will likely result in
crashes, since enetc_psi_create() cleans up everything after itself when
it returns an ERR_PTR().

- Couple of virtual vs physical address confusion fixes - Rework locking in dcssblk driver to address a lockdep warning - Remove support for "noexec" kernel command line option since there is no use case where it would make sense - Simplify kernel mapping setup and get rid of quite a bit of code - Add architecture specific __set_memory_yy() functions which allow to modify kernel mappings. Unlike the set_memory_xx() variants they take void pointer start and end parameters, which allows to use them without the usual casts, and also to use them on areas larger than 8TB. Note that the set_memory_xx() family comes with an int num_pages parameter which overflows with 8TB. This could be addressed by changing the num_pages parameter to unsigned long, however requires to change all architectures, since the module code expects an int parameter (see module_set_memory()). This was indeed an issue since for debug_pagealloc() we call set_memory_4k() on the whole identity mapping.

ntfs3: drop inode references in ntfs_put_super()
Recently we moved most cleanup from ntfs_put_super() into
ntfs3_kill_sb() as part of a bigger cleanup. This accidently also moved
dropping inode references stashed in ntfs3's sb->s_fs_info from
@sb->put_super() to @sb->kill_sb(). But generic_shutdown_super()
verifies that there are no busy inodes past sb->put_super(). Fix this
and disentangle dropping inode references from freeing @sb->s_fs_info.

vfs: mostly undo glibc turning 'fstat()' into 'fstatat(AT_EMPTY_PATH)'
Mateusz reports that glibc turns 'fstat()' calls into 'fstatat()', and that seems to have been going on for quite a long time due to glibc having tried to simplify its stat logic into just one point. This turns out to cause completely unnecessary overhead, where we then go off and allocate the kernel side pathname, and actually look up the empty path. Sure, our path lookup is quite optimized, but it still causes a fair bit of allocation overhead and a couple of completely unnecessary rounds of lockref accesses etc. This is all hopefully getting fixed in user space, and there is a patch floating around for just having glibc use the native fstat() system call. But even with the current situation we can at least improve on things by catching the situation and short-circuiting it. Note that this is still measurably slower than just a plain 'fstat()', since just checking that the filename is actually empty is somewhat expensive due to inevitable user space access overhead from the kernel (ie verifying pointers, and SMAP on x86). But it's still quite a bit faster than actually looking up the path for real. To quote numers from Mateusz: "Sapphire Rapids, will-it-scale, ops/s stock fstat 5088199 patched fstat 7625244 (+49%) real fstat 8540383 (+67% / +12%)" where that 'stock fstat' is the glibc translation of fstat into fstatat() with an empty path, the 'patched fstat' is with this short circuiting of the path lookup, and the 'real fstat' is the actual native fstat() system call with none of this overhead.

This time almost all fixes are for old bugs: First patch fixes a 4-byte stack OOB write, from myself. This was broken ever since nftables was switches from 128 to 32bit register addressing in v4.1. 2nd patch fixes an out-of-bounds read. This has been broken ever since xt_osf got added in 2.6.31, the bug was then just moved around during refactoring, from Wander Lairson Costa. 3rd patch adds a missing enum description, from Phil Sutter. 4th patch fixes a UaF inftables that occurs when userspace adds elements with a timeout so small that expiration happens while the transaction is still in progress. Fix from Pablo Neira Ayuso. Patch 5 fixes a memory out of bounds access, this was broken since v4.20. Patch from Kyle Zeng and Jozsef Kadlecsik. Patch 6 fixes another bogus memory access when building audit record.

net: hns3: remove GSO partial feature bit
HNS3 NIC does not support GSO partial packets segmentation. Actually tunnel
packets for example NvGRE packets segment offload and checksum offload is
already supported. There is no need to keep gso partial feature bit. So
this patch removes it.

net: hns3: fix invalid mutex between tc qdisc and dcb ets command issue
We hope that tc qdisc and dcb ets commands can not be used crosswise.
If we want to use any of the commands to configure tc,
We must use the other command to clear the existing configuration.
However, when we configure a single tc with tc qdisc,
we can still configure it with dcb ets.
Because we use mqprio_active as the tag of tc qdisc configuration,
but with dcb ets, we do not check mqprio_active.
This patch fix this issue by check mqprio_active before
executing the dcb ets command. and add dcb_ets_active to
replace HCLGE_FLAG_DCB_ENABLE and HCLGE_FLAG_MQPRIO_ENABLE
at the hclge layer,

net: hns3: fix tx timeout issue
Currently, the driver knocks the ring doorbell before updating
the ring->last_to_use in tx flow. if the hardware transmiting
packet and napi poll scheduling are fast enough, it may get
the old ring->last_to_use in drivers' napi poll.
In this case, the driver will think the tx is not completed, and
return directly without clear the flag __QUEUE_STATE_STACK_XOFF,
which may cause tx timeout.

net: phy: Provide Module 4 KSZ9477 errata (DS80000754C)
The KSZ9477 errata points out (in 'Module 4') the link up/down problems
when EEE (Energy Efficient Ethernet) is enabled in the device to which
the KSZ9477 tries to auto negotiate.
The suggested workaround is to clear advertisement of EEE for PHYs in
this chip driver.
To avoid regressions with other switch ICs the new MICREL_NO_EEE flag
has been introduced.
Moreover, the in-register disablement of MMD_DEVICE_ID_EEE_ADV.MMD_EEE_ADV
MMD register is removed, as this code is both; now executed too late
(after previous rework of the PHY and DSA for KSZ switches) and not
required as setting all members of eee_broken_modes bit field prevents
the KSZ9477 from advertising EEE.

netfilter: ipset: add the missing IP_SET_HASH_WITH_NET0 macro for ip_set_hash_netportnet.c
The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can
lead to the use of wrong `CIDR_POS(c)` for calculating array offsets,
which can lead to integer underflow. As a result, it leads to slab

netfilter: nftables: exthdr: fix 4-byte stack OOB write
If priv->len is a multiple of 4, then dst[len / 4] can write past the destination array which leads to stack corruption. This construct is necessary to clean the remainder of the register in case ->len is NOT a multiple of the register size, so make it conditional just like nft_payload.c does. The bug was added in 4.1 cycle and then copied/inherited when tcp/sctp and ip option support was added. Bug reported by Zero Day Initiative project (ZDI-CAN-21950, ZDI-CAN-21951, ZDI-CAN-21961).

It complains about acquiring a local_lock while holding a raw_spin_lock.
It means it should not allocate memory while holding a raw_spin_lock
since it is not safe for RT.
raw_spin_lock is needed because bpf_local_storage supports tracing
context. In particular for task local storage, it is easy to
get a "current" task PTR_TO_BTF_ID in tracing bpf prog.
However, task (and cgroup) local storage has already been moved to
bpf mem allocator which can be used after raw_spin_lock.
The splat is for the sk storage. For sk (and inode) storage,
it has not been moved to bpf mem allocator. Using raw_spin_lock or not,
kzalloc(GFP_ATOMIC) could theoretically be unsafe in tracing context.
However, the local storage helper requires a verifier accepted
sk pointer (PTR_TO_BTF_ID), it is hypothetical if that (mean running
a bpf prog in a kzalloc unsafe context and also able to hold a verifier
accepted sk pointer) could happen.
This patch avoids kzalloc after raw_spin_lock to silent the splat.
There is an existing kzalloc before the raw_spin_lock. At that point,
a kzalloc is very likely required because a lookup has just been done
before. Thus, this patch always does the kzalloc before acquiring
the raw_spin_lock and remove the later kzalloc usage after the
raw_spin_lock. After this change, it will have a charge and then
uncharge during the syscall bpf_map_update_elem() code path.
This patch opts for simplicity and not continue the old
optimization to save one charge and uncharge.
This issue is dated back to the very first commit of bpf_sk_storage
which had been refactored multiple times to create task, inode, and
cgroup storage. This patch uses a Fixes tag with a more recent
commit that should be easier to do backport.

s390/bpf: Pass through tail call counter in trampolines
s390x eBPF programs use the following extension to the s390x calling
convention: tail call counter is passed on stack at offset
STK_OFF_TCCNT, which callees otherwise use as scratch space.
Currently trampoline does not respect this and clobbers tail call
counter. This breaks enforcing tail call limits in eBPF programs, which
have trampolines attached to them.
Fix by forwarding a copy of the tail call counter to the original eBPF
program in the trampoline (for fexit), and by restoring it at the end
of the trampoline (for fentry).

bpf: Assign bpf_tramp_run_ctx::saved_run_ctx before recursion check.
__bpf_prog_enter_recur() assigns bpf_tramp_run_ctx::saved_run_ctx before
performing the recursion check which means in case of a recursion
__bpf_prog_exit_recur() uses the previously set bpf_tramp_run_ctx::saved_run_ctx
value.
__bpf_prog_enter_sleepable_recur() assigns bpf_tramp_run_ctx::saved_run_ctx
after the recursion check which means in case of a recursion
__bpf_prog_exit_sleepable_recur() uses an uninitialized value. This does not
look right. If I read the entry trampoline code right, then bpf_tramp_run_ctx
isn't initialized upfront.
Align __bpf_prog_enter_sleepable_recur() with __bpf_prog_enter_recur() and
set bpf_tramp_run_ctx::saved_run_ctx before the recursion check is made.
Remove the assignment of saved_run_ctx in kern_sys_bpf() since it happens
a few cycles later.

bpf: Invoke __bpf_prog_exit_sleepable_recur() on recursion in kern_sys_bpf().
If __bpf_prog_enter_sleepable_recur() detects recursion then it returns
0 without undoing rcu_read_lock_trace(), migrate_disable() or
decrementing the recursion counter. This is fine in the JIT case because
the JIT code will jump in the 0 case to the end and invoke the matching
exit trampoline (__bpf_prog_exit_sleepable_recur()).
This is not the case in kern_sys_bpf() which returns directly to the
caller with an error code.
Add __bpf_prog_exit_sleepable_recur() as clean up in the recursion case.

net: phylink: fix sphinx complaint about invalid literal
sphinx complains about the use of "%PHYLINK_PCS_NEG_*":

Documentation/networking/kapi:144: ./include/linux/phylink.h:633: WARNING: Inline literal start-string without end-string.
These are not valid symbols so drop the '%' prefix.
Alternatively we could use %PHYLINK_PCS_NEG_\* (escape the *)
or use normal literal ``PHYLINK_PCS_NEG_*`` but there is already
a handful of un-adorned DEFINE_* in this file.

Merge branch 'sja1105-fixes'
Vladimir Oltean says: ==================== tc-cbs offload fixes for SJA1105 DSA Yanan Yang has pointed out to me that certain tc-cbs offloaded configurations do not appear to do any shaping on the LS1021A-TSN board (SJA1105T). This is due to an apparent documentation error that also made its way into the driver, which patch 1/3 now fixes. While investigating and then testing, I've found 2 more bugs, which are patches 2/3 and 3/3. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

net: dsa: sja1105: complete tc-cbs offload support on SJA1110
The blamed commit left this delta behind:
struct sja1105_cbs_entry {
- u64 port;
- u64 prio;
+ u64 port; /* Not used for SJA1110 */
+ u64 prio; /* Not used for SJA1110 */
u64 credit_hi;
u64 credit_lo;
u64 send_slope;
u64 idle_slope;
};
but did not actually implement tc-cbs offload fully for the new switch.
The offload is accepted, but it doesn't work.
The difference compared to earlier switch generations is that now, the
table of CBS shapers is sparse, because there are many more shapers, so
the mapping between a {port, prio} and a table index is static, rather
than requiring us to store the port and prio into the sja1105_cbs_entry.
So, the problem is that the code programs the CBS shaper parameters at a
dynamic table index which is incorrect.
All that needs to be done for SJA1110 CBS shapers to work is to bypass
the logic which allocates shapers in a dense manner, as for SJA1105, and
use the fixed mapping instead.

net: dsa: sja1105: fix -ENOSPC when replacing the same tc-cbs too many times
After running command [2] too many times in a row:
[1] $ tc qdisc add dev sw2p0 root handle 1: mqprio num_tc 8 \
map 0 1 2 3 4 5 6 7 queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 hw 0
[2] $ tc qdisc replace dev sw2p0 parent 1:1 cbs offload 1 \
idleslope 120000 sendslope -880000 locredit -1320 hicredit 180
(aka more than priv->info->num_cbs_shapers times)
we start seeing the following error message:
Error: Specified device failed to setup cbs hardware offload.
This comes from the fact that ndo_setup_tc(TC_SETUP_QDISC_CBS) presents
the same API for the qdisc create and replace cases, and the sja1105
driver fails to distinguish between the 2. Thus, it always thinks that
it must allocate the same shaper for a {port, queue} pair, when it may
instead have to replace an existing one.
