[ Upstream commit 638f32604385fd23059985da8de918e9c18f0b98 ]
AF_UNIX socket tracks the most recent OOB packet (in its receive queue)
with an `oob_skb` pointer. BPF redirecting does not account for that: when
an OOB packet is moved between sockets, `oob_skb` is left outdated. This
results in a single skb that may be accessed from two different sockets.
Take the easy way out: silently drop MSG_OOB data targeting any socket that
is in a sockmap or a sockhash. Note that such silent drop is akin to the
fate of redirected skb's scm_fp_list (SCM_RIGHTS, SCM_CREDENTIALS).
For symmetry, forbid MSG_OOB in unix_bpf_recvmsg().
Fixes: 314001f0bf92 ("af_unix: Add OOB support")

commit 19b815ed71aadee9a2d31b7a700ef61ae8048010 upstream.
Chanctx emulation didn't info IEEE80211_CONF_CHANGE_CHANNEL to drivers
during ieee80211_restart_hw (ieee80211_emulate_add_chanctx). It caused
non-chanctx drivers to not stand on the correct channel after recovery.
RX then behaved abnormally. Finally, disconnection/reconnection occurred.
So, set IEEE80211_CONF_CHANGE_CHANNEL when in_reconfig.

commit abb9a68d2c64dd9b128ae1f2e635e4d805e7ce64 upstream.
When the source address is selected, the scope must be checked. For
example, if a loopback address is assigned to the vrf device, it must not
be chosen for packets sent outside.

commit 6807352353561187a718e87204458999dbcbba1b upstream.
By default, an address assigned to the output interface is selected when
the source address is not specified. This is problematic when a route,
configured in a vrf, uses an interface from another vrf (aka route leak).
The original vrf does not own the selected source address.
Let's add a check against the output interface and call the appropriate
function to select the source address.

commit 79eecf631c14e7f4057186570ac20e2cfac3802e upstream.
The issue initially stems from libpcap. The ethertype will be overwritten
as the VLAN TPID if the network interface lacks hardware VLAN offloading.
In the outbound packet path, if hardware VLAN offloading is unavailable,
the VLAN tag is inserted into the payload but then cleared from the sk_buff
struct. Consequently, this can lead to a false negative when checking for
the presence of a VLAN tag, causing the packet sniffing outcome to lack
VLAN tag information (i.e., TCI-TPID). As a result, the packet capturing
tool may be unable to parse packets as expected.
The TCI-TPID is missing because the prb_fill_vlan_info() function does not
modify the tp_vlan_tci/tp_vlan_tpid values, as the information is in the
payload and not in the sk_buff struct. The skb_vlan_tag_present() function
only checks vlan_all in the sk_buff struct. In cooked mode, the L2 header
is stripped, preventing the packet capturing tool from determining the
correct TCI-TPID value. Additionally, the protocol in SLL is incorrect,
which means the packet capturing tool cannot parse the L3 header correctly.

[ Upstream commit f036e68212c11e5a7edbb59b5e25299341829485 ]
The TOS value that is returned to user space in the route get reply is
the one with which the lookup was performed ('fl4->flowi4_tos'). This is
fine when the matched route is configured with a TOS as it would not
match if its TOS value did not match the one with which the lookup was
performed.
However, matching on TOS is only performed when the route's TOS is not
zero. It is therefore possible to have the kernel incorrectly return a
non-zero TOS:
# ip link add name dummy1 up type dummy
# ip address add 192.0.2.1/24 dev dummy1
# ip route get fibmatch 192.0.2.2 tos 0xfc
192.0.2.0/24 tos 0x1c dev dummy1 proto kernel scope link src 192.0.2.1
Fix by instead returning the DSCP field from the FIB result structure
which was populated during the route lookup.
Output after the patch:
# ip link add name dummy1 up type dummy
# ip address add 192.0.2.1/24 dev dummy1
# ip route get fibmatch 192.0.2.2 tos 0xfc
192.0.2.0/24 dev dummy1 proto kernel scope link src 192.0.2.1
Extend the existing selftests to not only verify that the correct route
is returned, but that it is also returned with correct "tos" value (or
without it).

[ Upstream commit 120f1c857a73e52132e473dee89b340440cb692b ]
The following splat is easy to reproduce upstream as well as in -stable
kernels. Florian Westphal provided the following commit:
d1dab4f71d37 ("net: add and use __skb_get_hash_symmetric_net")
but this complementary fix has been also suggested by Willem de Bruijn
and it can be easily backported to -stable kernel which consists in
using DEBUG_NET_WARN_ON_ONCE instead to silence the following splat
given __skb_get_hash() is used by the nftables tracing infrastructure to
to identify packets in traces.

[ Upstream commit 791a615b7ad2258c560f91852be54b0480837c93 ]
The initial buffer has to be inited to all-ones, but it must restrict
it to the size of the first field, not the total field size.
After each round in the map search step, the result and the fill map
are swapped, so if we have a set where f->bsize of the first element
is smaller than m->bsize_max, those one-bits are leaked into future
rounds result map.
This makes pipapo find an incorrect matching results for sets where
first field size is not the largest.
Followup patch adds a test case to nft_concat_range.sh selftest script.
Thanks to Stefano Brivio for pointing out that we need to zero out
the remainder explicitly, only correcting memset() argument isn't enough.

[ Upstream commit 6258cf25d5e3155c3219ab5a79b970eef7996356 ]
Prior to the commit identified below, call_transmit_status() would
handle -EPERM and other errors related to an unreachable server by
falling through to call_status() which added a 3-second delay and
handled the failure as a timeout.
Since that commit, call_transmit_status() falls through to
handle_bind(). For UDP this moves straight on to handle_connect() and
handle_transmit() so we immediately retransmit - and likely get the same
error.
This results in an indefinite loop in __rpc_execute() which triggers a
soft-lockup warning.
For the errors that indicate an unreachable server,
call_transmit_status() should fall back to call_status() as it did
before. This cannot cause the thundering herd that the previous patch
was avoiding, as the call_status() will insert a delay.

Avoid FastReg operations getting MW_BIND_ERR after a reconnect.
rpcrdma_reqs_reset() is called on transport tear-down to get each
rpcrdma_req back into a clean state.
MRs on req->rl_registered are waiting for a FastReg, are already
registered, or are waiting for invalidation. If the transport is
being torn down when reqs_reset() is called, the matching LocalInv
might never be posted. That leaves these MR registered /and/ on
req->rl_free_mrs, where they can be re-used for the next
connection.
Since xprtrdma does not keep specific track of the MR state, it's
not possible to know what state these MRs are in, so the only safe
thing to do is release them immediately.

If a port is blocking in the common instance but forwarding in an MST
instance, traffic egressing the bridge will be dropped because the
state of the common instance is overriding that of the MST instance.
Fix this by skipping the port state check in MST mode to allow
checking the vlan state via br_allowed_egress(). This is similar to
what happens in br_handle_frame_finish() when checking ingress
traffic, which was introduced in the change below.

[ Upstream commit 59a931c5b732ca5fc2ca727f5a72aeabaafa85ec ]
If the driver uses a page pool, it creates a page pool with
page_pool_create().
The reference count of page pool is 1 as default.
A page pool will be destroyed only when a reference count reaches 0.
page_pool_destroy() is used to destroy page pool, it decreases a
reference count.
When a page pool is destroyed, ->disconnect() is called, which is
mem_allocator_disconnect().
This function internally acquires mutex_lock().
If the driver uses XDP, it registers a memory model with
xdp_rxq_info_reg_mem_model().
The xdp_rxq_info_reg_mem_model() internally increases a page pool
reference count if a memory model is a page pool.
Now the reference count is 2.
To destroy a page pool, the driver should call both page_pool_destroy()
and xdp_unreg_mem_model().
The xdp_unreg_mem_model() internally calls page_pool_destroy().
Only page_pool_destroy() decreases a reference count.
If a driver calls page_pool_destroy() then xdp_unreg_mem_model(), we
will face an invalid wait context warning.
Because xdp_unreg_mem_model() calls page_pool_destroy() with
rcu_read_lock().
The page_pool_destroy() internally acquires mutex_lock().

To fix this problem, it uses rhashtable_lookup_fast() instead of
rhashtable_lookup() with rcu_read_lock().
Using xa without rcu_read_lock() here is safe.
xa is freed by __xdp_mem_allocator_rcu_free() and this is called by
call_rcu() of mem_xa_remove().
The mem_xa_remove() is called by page_pool_destroy() if a reference
count reaches 0.
The xa is already protected by the reference count mechanism well in the
control plane.
So removing rcu_read_lock() for page_pool_destroy() is safe.

[ 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.

[ Upstream commit 07b87f9eea0c30675084d50c82532d20168da009 ]
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
that need to be cleared we add another list where skbs
linked to that are unlinked from the lists (deleted)
but not yet freed.

[ 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.
Fixes: 304b44f0d5a4 ("xfrm: Add dir validation to "in" data path lookup")

CONFIG_ARCH_NO_SG_CHAIN is defined
[ Upstream commit 3ac14b9dfbd345e891d48d89f6c2fa519848f0f4 ]
SG_MAX_SINGLE_ALLOC is used to limit maximum number of entries that
will be allocated in one piece of scatterlist. When the entries of
scatterlist exceeds SG_MAX_SINGLE_ALLOC, sg chain will be used. From
commit 7c703e54cc71 ("arch: switch the default on ARCH_HAS_SG_CHAIN"),
we can know that the macro CONFIG_ARCH_NO_SG_CHAIN is used to identify
whether sg chain is supported. So, SMC-R's rmb buffer should be limited
by SG_MAX_SINGLE_ALLOC only when the macro CONFIG_ARCH_NO_SG_CHAIN is
defined.

[ Upstream commit fde6f897f2a184546bf5516ac736523ef24dc6a7 ]
These functions have races when they:
1) Write sk->sk_err
2) call sk_error_report(sk)
3) call tcp_done(sk)
As described in prior patches in this series:
An smp_wmb() is missing.
We should call tcp_done() before sk_error_report(sk)
to have consistent tcp_poll() results on SMP hosts.
Use tcp_done_with_error() where we centralized the
correct sequence.

[ Upstream commit 853c3bd7b7917670224c9fe5245bd045cac411dd ]
I noticed flakes in a packetdrill test, expecting an epoll_wait()
to return EPOLLERR | EPOLLHUP on a failed connect() attempt,
after multiple SYN retransmits. It sometimes return EPOLLERR only.
The issue is that tcp_write_err():
1) writes an error in sk->sk_err,
2) calls sk_error_report(),
3) then calls tcp_done().
tcp_done() is writing SHUTDOWN_MASK into sk->sk_shutdown,
among other things.
Problem is that the awaken user thread (from 2) sk_error_report())
might call tcp_poll() before tcp_done() has written sk->sk_shutdown.
tcp_poll() only sees a non zero sk->sk_err and returns EPOLLERR.
This patch fixes the issue by making sure to call sk_error_report()
after tcp_done().
tcp_write_err() also lacks an smp_wmb().
We can reuse tcp_done_with_error() to factor out the details,
as Neal suggested.

[ Upstream commit 96f887a612e4cda89efc3f54bc10c1997e3ab0e9 ]
xmit() functions should consume skb or return error codes in error
paths.
When the configuration "CONFIG_INET_ESPINTCP" is not set, the
implementation of the function "esp_output_tail_tcp" violates this rule.
The function frees the skb and returns the error code.
This change removes the kfree_skb from both functions, for both
esp4 and esp6.
WARN_ON is added because esp_output_tail_tcp() should never be called if
CONFIG_INET_ESPINTCP is not set.

When user submits a rxfh set command without touching XFRM_SYM_XOR,
rxfh.input_xfrm is set to RXH_XFRM_NO_CHANGE, which is equal to 0xff.
Testing if (rxfh.input_xfrm & RXH_XFRM_SYM_XOR &&
!ops->cap_rss_sym_xor_supported)
return -EOPNOTSUPP;
Will always be true on devices that don't set cap_rss_sym_xor_supported,
since rxfh.input_xfrm & RXH_XFRM_SYM_XOR is always true, if input_xfrm
was not set, i.e RXH_XFRM_NO_CHANGE=0xff, which will result in failure
of any command that doesn't require any change of XFRM, e.g RSS context
or hash function changes.
To avoid this breakage, test if rxfh.input_xfrm != RXH_XFRM_NO_CHANGE
before testing other conditions. Note that the problem will only trigger
with XFRM-aware userspace, old ethtool CLI would continue to work.
