5b08892910 selftests/bpf: Close obj in error path in xdp_adjust_tail
[ Upstream commit 52b49ec1b2c78deb258596c3b231201445ef5380 ]

If bpf_object__load() fails in test_xdp_adjust_frags_tail_grow(), "obj"
opened before this should be closed. So use "goto out" to close it instead
of using "return" here.

This is because BPF trampoline is not implemented on Loongarch yet,
"link" returned by bpf_map__attach_struct_ops() is NULL. test_progs
crashs when this NULL link passes to bpf_link__update_map(). This
patch adds NULL checks for all links in bpf_tcp_ca to fix these errors.
If "link" is NULL, goto the newly added label "out" to destroy the skel.

v2:
 - use "goto out" instead of "return" as Eduard suggested.

29ca547e87 locking/rwsem: Add __always_inline annotation to __down_write_common() and inlined callers
[ Upstream commit e81859fe64ad42dccefe134d1696e0635f78d763 ]

Apparently despite it being marked inline, the compiler
may not inline __down_write_common() which makes it difficult
to identify the cause of lock contention, as the wchan of the
blocked function will always be listed as __down_write_common().

So add __always_inline annotation to the common function (as
well as the inlined helper callers) to force it to be inlined
so a more useful blocking function will be listed (via wchan).

This mirrors commit 92cc5d00a431 ("locking/rwsem: Add
__always_inline annotation to __down_read_common() and inlined
callers") which did the same for __down_read_common.

I sort of worry that I'm playing wack-a-mole here, and talking
with compiler people, they tell me inline means nothing, which
makes me want to cry a little. So I'm wondering if we need to
replace all the inlines with __always_inline, or remove them
because either we mean something by it, or not.

0faaa5f29e bpf: helpers: fix bpf_wq_set_callback_impl signature
[ Upstream commit f56f4d541eab1ae060a46b56dd6ec9130d6e3a98 ]

I realized this while having a map containing both a struct bpf_timer and
a struct bpf_wq: the third argument provided to the bpf_wq callback is
not the struct bpf_wq pointer itself, but the pointer to the value in
the map.

Which means that the users need to double cast the provided "value" as
this is not a struct bpf_wq *.

This is a change of API, but there doesn't seem to be much users of bpf_wq
right now, so we should be able to go with this right now.

[ Upstream commit b5d14b0c6716fad7f0c94ac6e1d6f60a49f985c7 ]

When user issues a connection with a different SSID than the one
virt_wifi has advertised, the __cfg80211_connect_result() will
trigger the warning: WARN_ON(bss_not_found).

The issue is because the connection code in virt_wifi does not
check the SSID from user space (it only checks the BSSID), and
virt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESS
even if the SSID is different from the one virt_wifi has advertised.
Eventually cfg80211 won't be able to find the cfg80211_bss and generate
the warning.

Fixed it by checking the SSID (from user space) in the connection code.

574c740486 xfrm: call xfrm_dev_policy_delete when kill policy
[ Upstream commit 89a2aefe4b084686c2ffc1ee939585111ea4fc0f ]

xfrm_policy_kill() is called at different places to delete xfrm
policy. It will call xfrm_pol_put(). But xfrm_dev_policy_delete() is
not called to free the policy offloaded to hardware.

The three commits cited here are to handle this issue by calling
xfrm_dev_policy_delete() outside xfrm_get_policy(). But they didn't
cover all the cases. An example, which is not handled for now, is
xfrm_policy_insert(). It is called when XFRM_MSG_UPDPOLICY request is
received. Old policy is replaced by new one, but the offloaded policy
is not deleted, so driver doesn't have the chance to release hardware
resources.

To resolve this issue for all cases, move xfrm_dev_policy_delete()
into xfrm_policy_kill(), so the offloaded policy can be deleted from
hardware when it is called, which avoids hardware resources leakage.

In rtw89_sta_info_get_iter() 'status->he_gi' is compared to array size.
But then 'rate->he_gi' is used as array index instead of 'status->he_gi'.
This can lead to go beyond array boundaries in case of 'rate->he_gi' is

"copy-paste" mistake.

3fd761e3ce perf/x86/amd/uncore: Fix DF and UMC domain identification
[ Upstream commit 57e11990f45f89bc29d0f84dd7b13a4e4263eeb2 ]

For uncore PMUs, a single context is shared across all CPUs in a domain.
The domain can be a CCX, like in the case of the L3 PMU, or a socket,
like in the case of DF and UMC PMUs. This information is available via
the PMU's cpumask.

For contexts shared across a socket, the domain is currently determined
from topology_die_id() which is incorrect after the introduction of
commit 63edbaa48a57 ("x86/cpu/topology: Add support for the AMD
0x80000026 leaf") as it now returns a CCX identifier on Zen 4 and later
systems which support CPUID leaf 0x80000026.

Use topology_logical_package_id() instead as it always returns a socket
identifier irrespective of the availability of CPUID leaf 0x80000026.

[ Upstream commit 43deb76b19663a96ec2189d8f4eb9a9dc2d7623f ]

The default aux_watermark is half the AUX area buffer size. In general,
on a 64-bit architecture, the AUX area buffer size could be a bigger than
fits in a 32-bit type, but the calculation does not allow for that
possibility.

However the aux_watermark value is recorded in a u32, so should not be
more than U32_MAX either.

Fix by doing the calculation in a correctly sized type, and limiting the
result to U32_MAX.

[ Upstream commit dbc48c8f41c208082cfa95e973560134489e3309 ]

nr_pages is unsigned long but gets passed to rb_alloc_aux() as an int,
and is stored as an int.

Only power-of-2 values are accepted, so if nr_pages is a 64_bit value, it
will be passed to rb_alloc_aux() as zero.

That is not ideal because:
 1. the value is incorrect
 2. rb_alloc_aux() is at risk of misbehaving, although it manages to
 return -ENOMEM in that case, it is a result of passing zero to get_order()
 even though the get_order() result is documented to be undefined in that
 case.

Fix by simply validating the maximum supported value in the first place.
Use -ENOMEM error code for consistency with the current error code that
is returned in that case.

Zero-extending results of atomic probe operations fails with:

3e6a1b1b17 riscv, bpf: Fix out-of-bounds issue when preparing trampoline image
[ Upstream commit 9f1e16fb1fc9826001c69e0551d51fbbcd2d74e9 ]

We get the size of the trampoline image during the dry run phase and
allocate memory based on that size. The allocated image will then be
populated with instructions during the real patch phase. But after
commit 26ef208c209a ("bpf: Use arch_bpf_trampoline_size"), the `im`
argument is inconsistent in the dry run and real patch phase. This may
cause emit_imm in RV64 to generate a different number of instructions
when generating the 'im' address, potentially causing out-of-bounds
issues. Let's emit the maximum number of instructions for the "im"
address during dry run to fix this problem.

[ Upstream commit d0b4b8ef083ca46d5d318e66a30fb80e0abbb90d ]

TX power index is read from the efuse on init, the values get written to
the TX power registers when the channel gets switched.

When the chip has not yet been calibrated, the efuse values are 0xFF,
which on some boards leads to USB timeouts for reading/writing registers
after the first frames have been sent.

The vendor driver (v5.11.5-1) checks for these invalid values and sets
default values instead. Implement something similar in
rtl8188fu_parse_efuse().

[ Upstream commit 1eeafd64c7b455381b77c546e41bc267e13e2809 ]

Currently, the Rx data path only supports parsing peer metadata of version
zero. However, the QCN9274 platform configures the peer metadata version
as V1B. When V1B peer metadata is parsed using the version zero logic,
invalid data is populated, causing valid packets to be dropped. To address
this issue, refactor the peer metadata version and add the version based
parsing to populate the data from peer metadata correctly.

When offloading xfrm states to hardware, the offloading
device is attached to the skbs secpath. If a skb is free
is deferred, an unregister netdevice hangs because the
netdevice is still refcounted.

Fix this by removing the netdevice from the xfrm states
when the netdevice is unregistered. To find all xfrm states

linked to that are unlinked from the lists (deleted)

2845db7bed libbpf: Skip base btf sanity checks
[ Upstream commit c73a9683cb21012b6c0f14217974837151c527a8 ]

When upgrading to libbpf 1.3 we noticed a big performance hit while
loading programs using CORE on non base-BTF symbols. This was tracked
down to the new BTF sanity check logic. The issue is the base BTF
definitions are checked first for the base BTF and then again for every
module BTF.

Loading 5 dummy programs (using libbpf-rs) that are using CORE on a
non-base BTF symbol on my system:
- Before this fix: 3s.
- With this fix: 0.1s.

Fix this by only checking the types starting at the BTF start id. This
should ensure the base BTF is still checked as expected but only once
(btf->start_id == 1 when creating the base BTF), and then only
additional types are checked for each module BTF.

aeb79296c6 libbpf: Checking the btf_type kind when fixing variable offsets
[ Upstream commit cc5083d1f3881624ad2de1f3cbb3a07e152cb254 ]

I encountered an issue when building the test_progs from the repository [1]:

  $ pwd
  /work/Qemu/x86_64/linux-6.10-rc2/tools/testing/selftests/bpf/

  $ make test_progs V=1
  [...]
  ./tools/sbin/bpftool gen object ./ip_check_defrag.bpf.linked2.o ./ip_check_defrag.bpf.linked1.o
  libbpf: failed to find symbol for variable 'bpf_dynptr_slice' in section '.ksyms'
  Error: failed to link './ip_check_defrag.bpf.linked1.o': No such file or directory (2)
  [...]

Upon investigation, I discovered that the btf_types referenced in the '.ksyms'
section had a kind of BTF_KIND_FUNC instead of BTF_KIND_VAR:

  $ bpftool btf dump file ./ip_check_defrag.bpf.linked1.o
  [...]
  [2] DATASEC '.ksyms' size=0 vlen=2
        type_id=16 offset=0 size=0 (FUNC 'bpf_dynptr_from_skb')
        type_id=17 offset=0 size=0 (FUNC 'bpf_dynptr_slice')
  [...]
  [16] FUNC 'bpf_dynptr_from_skb' type_id=82 linkage=extern
  [17] FUNC 'bpf_dynptr_slice' type_id=85 linkage=extern
  [...]

For a detailed analysis, please refer to [2]. We can add a kind checking to
fix the issue.

00e09f86c6 net: dsa: ksz_common: Allow only up to two HSR HW offloaded ports for KSZ9477
[ Upstream commit dcec8d291da8813b5e1c7c0967ae63463a8521f6 ]

The KSZ9477 allows HSR in-HW offloading for any of two selected ports.
This patch adds check if one tries to use more than two ports with
HSR offloading enabled.

The problem is with RedBox configuration (HSR-SAN) - when configuring:
ip link add name hsr0 type hsr slave1 lan1 slave2 lan2 interlink lan3 \
	supervision 45 version 1

The lan1 (port0) and lan2 (port1) are correctly configured as ports, which
can use HSR offloading on ksz9477.

However, when we do already have two bits set in hsr_ports, we need to
return (-ENOTSUPP), so the interlink port (lan3) would be used with
SW based HSR RedBox support.

Otherwise, I do see some strange network behavior, as some HSR frames are
visible on non-HSR network and vice versa.

This causes the switch connected to interlink port (lan3) to drop frames
and no communication is possible.

Moreover, conceptually - the interlink (i.e. HSR-SAN port - lan3/port2)
shall be only supported in software as it is also possible to use ksz9477
with only SW based HSR (i.e. port0/1 -> hsr0 with offloading, port2 ->
HSR-SAN/interlink, port4/5 -> hsr1 with SW based HSR).

[ Upstream commit c32fe1986f27cac329767d3497986e306cad1d5e ]

FEC_ECR_EN1588 bit gets cleared after MAC reset in `fec_stop()`, which
makes all 1588 functionality shut down, and all the extended registers
disappear, on link-down, making the adapter fall back to compatibility
"dumb mode". However, some functionality needs to be retained (e.g. PPS)
even without link.

40d7b3ed52 udf: Fix bogus checksum computation in udf_rename()
[ Upstream commit 27ab33854873e6fb958cb074681a0107cc2ecc4c ]

Syzbot reports uninitialized memory access in udf_rename() when updating
checksum of '..' directory entry of a moved directory. This is indeed
true as we pass on-stack diriter.fi to the udf_update_tag() and because
that has only struct fileIdentDesc included in it and not the impUse or
name fields, the checksumming function is going to checksum random stack
contents beyond the end of the structure. This is actually harmless
because the following udf_fiiter_write_fi() will recompute the checksum
from on-disk buffers where everything is properly included. So all that
is needed is just removing the bogus calculation.

73c19830cd xfrm: Log input direction mismatch error in one place
[ Upstream commit 15f5fe9e84839dcc9eaa69b08ced9d24cb464369 ]

Previously, the offload data path decrypted the packet before checking
the direction, leading to error logging and packet dropping. However,
dropped packets wouldn't be visible in tcpdump or audit log.

With this fix, the offload path, upon noticing SA direction mismatch,
will pass the packet to the stack without decrypting it. The L3 layer
will then log the error, audit, and drop ESP without decrypting or
decapsulating it.

This also ensures that the slow path records the error and audit log,
making dropped packets visible in tcpdump.

8ca4ec5a59 bpf: Make bpf_session_cookie() kfunc return long *
[ Upstream commit 2b8dd87332cd2782b5b3f0c423bd6693e487ed30 ]

We will soon be generating kfunc prototypes from BTF. As part of that,
we need to align the manual signatures in bpf_kfuncs.h with the actual
kfunc definitions. There is currently a conflicting signature for
bpf_session_cookie() w.r.t. return type.

The original intent was to return long * and not __u64 *. You can see
evidence of that intent in a3a5113393cc ("selftests/bpf: Add kprobe
session cookie test").

Fix conflict by changing kfunc definition.

ddbd23de1d wifi: iwlwifi: mvm: separate non-BSS/ROC EMLSR blocking
[ Upstream commit 5f1fee9644759d07f3d3a468389c7c18027083d7 ]

If non-BSS and remain-on-channel (ROC) blocking were to occur
simultaneously, they'd step on each other's toes, unblocking
when not yet supported. Disentangle these bits, and ROC doesn't
need to use the non_bss_link() function then.

94d2e5b786 wifi: iwlwifi: mvm: fix re-enabling EMLSR
[ Upstream commit bd40215b19d255b433a91a8bb8088937e5db4284 ]

When EMLSR gets unblocked, the current code checks if the last exit was
due to an EXIT reason (as opposed to a BLOCKING one), and if so, it
does nothing, as in this case a MLO scan was scheduled to run in 30
seconds.

But the code doesn't consider the time that passed from the last exit,
so if immediately after the exit a blocker occurred (e.g. non-BSS
interface), and lasts for more than 30 seconds, then the MLO scan and the
following link selection will decide not to enter EMLSR, and when the
unblocking event finally happens, the reason is still set to the EXIT one,
so it will do nothing, and we will not have the chance to re-enable EMLSR.

Fix this by checking also the time that has passed since the last exit,
only if it is less than 30 seconds, we can count on the scheduled MLO
scan.

Note that clearing the reason itself can't be done since it is needed
for the EMLSR prevention mechanism.
