net: annotate data-races on txq->xmit_lock_owner
commit 7a10d8c810cfad3e79372d7d1c77899d86cd6662 upstream.
syzbot found that __dev_queue_xmit() is reading txq->xmit_lock_owner
without annotations.
No serious issue there, let's document what is happening there.
BUG: KCSAN: data-race in __dev_queue_xmit / __dev_queue_xmit

net: sched: update default qdisc visibility after Tx queue cnt changes
[ Upstream commit 1e080f17750d1083e8a32f7b350584ae1cd7ff20 ]
mq / mqprio make the default child qdiscs visible. They only do
so for the qdiscs which are within real_num_tx_queues when the
device is registered. Depending on order of calls in the driver,
or if user space changes config via ethtool -L the number of
qdiscs visible under tc qdisc show will differ from the number
of queues. This is confusing to users and potentially to system
configuration scripts which try to make sure qdiscs have the
right parameters.
Add a new Qdisc_ops callback and make relevant qdiscs TTRT.
Note that this uncovers the "shortcut" created by
commit

net: Prevent infinite while loop in skb_tx_hash()
commit 0c57eeecc559ca6bc18b8c4e2808bc78dbe769b0 upstream.
Drivers call netdev_set_num_tc() and then netdev_set_tc_queue()
to set the queue count and offset for each TC. So the queue count
and offset for the TCs may be zero for a short period after dev->num_tc
has been set. If a TX packet is being transmitted at this time in the
code path netdev_pick_tx() -> skb_tx_hash(), skb_tx_hash() may see
nonzero dev->num_tc but zero qcount for the TC. The while loop that
keeps looping while hash >= qcount will not end.
Fix it by checking the TC's qcount to be nonzero before using it.

gro: ensure frag0 meets IP header alignment
commit 38ec4944b593fd90c5ef42aaaa53e66ae5769d04 upstream.
After commit 0f6925b3e8da ("virtio_net: Do not pull payload in skb->head")
Guenter Roeck reported one failure in his tests using sh architecture.
After much debugging, we have been able to spot silent unaligned accesses
in inet_gro_receive()
The issue at hand is that upper networking stacks assume their header
is word-aligned. Low level drivers are supposed to reserve NET_IP_ALIGN
bytes before the Ethernet header to make that happen.
This patch hardens skb_gro_reset_offset() to not allow frag0 fast-path
if the fragment is not properly aligned.
Some arches like x86, arm64 and powerpc do not care and define NET_IP_ALIGN
as 0, this extra check will be a NOP for them.
Note that if frag0 is not used, GRO will call pskb_may_pull()
as many times as needed to pull network and transport headers.

net: Treat __napi_schedule_irqoff() as __napi_schedule() on PREEMPT_RT
[ Upstream commit 8380c81d5c4fced6f4397795a5ae65758272bbfd ] __napi_schedule_irqoff() is an optimized version of __napi_schedule() which can be used where it is known that interrupts are disabled, e.g. in interrupt-handlers, spin_lock_irq() sections or hrtimer callbacks. On PREEMPT_RT enabled kernels this assumptions is not true. Force- threaded interrupt handlers and spinlocks are not disabling interrupts and the NAPI hrtimer callback is forced into softirq context which runs with interrupts enabled as well. Chasing all usage sites of __napi_schedule_irqoff() is a whack-a-mole game so make __napi_schedule_irqoff() invoke __napi_schedule() for PREEMPT_RT kernels. The callers of ____napi_schedule() in the networking core have been audited and are correct on PREEMPT_RT kernels as well.

can: dev: Move device back to init netns on owning netns delete
commit 3a5ca857079ea022e0b1b17fc154f7ad7dbc150f upstream.
When a non-initial netns is destroyed, the usual policy is to delete
all virtual network interfaces contained, but move physical interfaces
back to the initial netns. This keeps the physical interface visible
on the system.
CAN devices are somewhat special, as they define rtnl_link_ops even
if they are physical devices. If a CAN interface is moved into a
non-initial netns, destroying that netns lets the interface vanish
instead of moving it back to the initial netns. default_device_exit()
skips CAN interfaces due to having rtnl_link_ops set. Reproducer:
ip netns add foo
ip link set can0 netns foo
ip netns delete foo

To properly restore physical CAN devices to the initial netns on owning
netns exit, introduce a flag on rtnl_link_ops that can be set by drivers.
For CAN devices setting this flag, default_device_exit() considers them
non-virtual, applying the usual namespace move.
The issue was introduced in the commit mentioned below, as at that time
CAN devices did not have a dellink() operation.

net: disable netpoll on fresh napis
[ Upstream commit 96e97bc07e90f175a8980a22827faf702ca4cb30 ]
napi_disable() makes sure to set the NAPI_STATE_NPSVC bit to prevent
netpoll from accessing rings before init is complete. However, the
same is not done for fresh napi instances in netif_napi_add(),
even though we expect NAPI instances to be added as disabled.
This causes crashes during driver reconfiguration (enabling XDP,
changing the channel count) - if there is any printk() after
netif_napi_add() but before napi_enable().
To ensure memory ordering is correct we need to use RCU accessors.

net: place xmit recursion in softnet data
commit 97cdcf37b57e3f204be3000b9eab9686f38b4356 upstream. This fills a hole in softnet data, so no change in structure size. Also prepares for xmit_more placement in the same spot; skb->xmit_more will be removed in followup patch. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S.

If call_netdevice_notifiers() failed, then rollback_registered()
calls netdev_unregister_kobject() which holds the kobject. The
reference cannot be put because the netdev won't be add to todo
list, so it will leads a memleak, we need put the reference to
avoid memleak.

__netif_receive_skb_core: pass skb by reference
[ Upstream commit c0bbbdc32febd4f034ecbf3ea17865785b2c0652 ]
__netif_receive_skb_core may change the skb pointer passed into it (e.g.
in rx_handler). The original skb may be freed as a result of this
operation.
The callers of __netif_receive_skb_core may further process original skb
by using pt_prev pointer returned by __netif_receive_skb_core thus
leading to unpleasant effects.
The solution is to pass skb by reference into __netif_receive_skb_core.
v2: Added Fixes tag and comment regarding ppt_prev and skb invariant.

net: fix a potential recursive NETDEV_FEAT_CHANGE
[ Upstream commit dd912306ff008891c82cd9f63e8181e47a9cb2fb ] syzbot managed to trigger a recursive NETDEV_FEAT_CHANGE event between bonding master and slave. I managed to find a reproducer for this: ip li set bond0 up ifenslave bond0 eth0 brctl addbr br0 ethtool -K eth0 lro off brctl addif br0 bond0 ip li set br0 up When a NETDEV_FEAT_CHANGE event is triggered on a bonding slave, it captures this and calls bond_compute_features() to fixup its master's and other slaves' features. However, when syncing with its lower devices by netdev_sync_lower_features() this event is triggered again on slaves when the LRO feature fails to change, so it goes back and forth recursively until the kernel stack is exhausted.

net: Fix Tx hash bound checking
commit 6e11d1578fba8d09d03a286740ffcf336d53928c upstream. Fixes the lower and upper bounds when there are multiple TCs and traffic is on the the same TC on the same device. The lower bound is represented by 'qoffset' and the upper limit for hash value is 'qcount + qoffset'. This gives a clean Rx to Tx queue mapping when there are multiple TCs, as the queue indices for upper TCs will be offset by 'qoffset'. v2: Fixed commit description based on comments. Fixes: |

ANDROID: GKI: net: Add the get current NAPI context API
Commit 69235aa80090 ("net: Remove the get current NAPI context API")
removed the definition of get_current_napi_context() as rmnet_data
was no longer using it. However, the rmnet_data change to use its
NAPI in multiple contexts was prone to race in hotplug scenarios.
Add back get_current_napi_context() and current_napi to the
softnet_data struct.

core: Don't skip generic XDP program execution for cloned SKBs
[ Upstream commit ad1e03b2b3d4430baaa109b77bc308dc73050de3 ]
The current generic XDP handler skips execution of XDP programs entirely if
an SKB is marked as cloned. This leads to some surprising behaviour, as
packets can end up being cloned in various ways, which will make an XDP
program not see all the traffic on an interface.
This was discovered by a simple test case where an XDP program that always
returns XDP_DROP is installed on a veth device. When combining this with
the Scapy packet sniffer (which uses an AF_PACKET) socket on the sending
side, SKBs reliably end up in the cloned state, causing them to be passed
through to the receiving interface instead of being dropped. A minimal
reproducer script for this is included below.
This patch fixed the issue by simply triggering the existing linearisation
code for cloned SKBs instead of skipping the XDP program execution. This
behaviour is in line with the behaviour of the native XDP implementation
for the veth driver, which will reallocate and copy the SKB data if the SKB
is marked as shared.
Reproducer Python script (requires BCC and Scapy):

[ Upstream commit cb626bf566eb4433318d35681286c494f04fedcc ]
Netdev_register_kobject is calling device_initialize. In case of error
reference taken by device_initialize is not given up.
Drivers are supposed to call free_netdev in case of error. In non-error
case the last reference is given up there and device release sequence
is triggered. In error case this reference is kept and the release
sequence is never started.
Fix this by setting reg_state as NETREG_UNREGISTERED if registering
fails.
This is the rootcause for couple of memory leaks reported by Syzkaller:

net: fix bpf_xdp_adjust_head regression for generic-XDP
[ Upstream commit 065af355470519bd184019a93ac579f22b036045 ]
When generic-XDP was moved to a later processing step by commit
458bf2f224f0 ("net: core: support XDP generic on stacked devices.")
a regression was introduced when using bpf_xdp_adjust_head.
The issue is that after this commit the skb->network_header is now
changed prior to calling generic XDP and not after. Thus, if the header
is changed by XDP (via bpf_xdp_adjust_head), then skb->network_header
also need to be updated again. Fix by calling skb_reset_network_header().

net: core: support XDP generic on stacked devices.
[ Upstream commit 458bf2f224f04a513b0be972f8708e78ee2c986e ]
When a device is stacked like (team, bonding, failsafe or netvsc) the
XDP generic program for the parent device was not called.
Move the call to XDP generic inside __netif_receive_skb_core where
it can be done multiple times for stacked case.

net: core: limit nested device depth
[ Upstream commit 5343da4c17429efaa5fb1594ea96aee1a283e694 ]
Current code doesn't limit the number of nested devices.
Nested devices would be handled recursively and this needs huge stack
memory. So, unlimited nested devices could make stack overflow.
This patch adds upper_level and lower_level, they are common variables
and represent maximum lower/upper depth.
When upper/lower device is attached or dettached,
{lower/upper}_level are updated. and if maximum depth is bigger than 8,
attach routine fails and returns -EMLINK.
In addition, this patch converts recursive routine of
netdev_walk_all_{lower/upper} to iterator routine.
Test commands:
ip link add dummy0 type dummy
ip link add link dummy0 name vlan1 type vlan id 1
ip link set vlan1 up
for i in {2..55}
do
let A=$i-1
ip link add vlan$i link vlan$A type vlan id $i
done
ip link del dummy0
Splat looks like:

inet: protect against too small mtu values.
[ Upstream commit 501a90c945103e8627406763dac418f20f3837b2 ]
syzbot was once again able to crash a host by setting a very small mtu
on loopback device.
Let's make inetdev_valid_mtu() available in include/net/ip.h,
and use it in ip_setup_cork(), so that we protect both ip_append_page()
and __ip_append_data()
Also add a READ_ONCE() when the device mtu is read.
Pairs this lockless read with one WRITE_ONCE() in __dev_set_mtu(),
even if other code paths might write over this field.
Add a big comment in include/linux/netdevice.h about dev->mtu
needing READ_ONCE()/WRITE_ONCE() annotations.
Hopefully we will add the missing ones in followup patches.

net: do not abort bulk send on BQL status
[ Upstream commit fe60faa5063822f2d555f4f326c7dd72a60929bf ] Before calling dev_hard_start_xmit(), upper layers tried to cook optimal skb list based on BQL budget. Problem is that GSO packets can end up comsuming more than the BQL budget. Breaking the loop is not useful, since requeued packets are ahead of any packets still in the qdisc. It is also more expensive, since next TX completion will push these packets later, while skbs are not in cpu caches. It is also a behavior difference with TSO packets, that can break the BQL limit by a large amount. Note that drivers should use __netdev_tx_sent_queue() in order to have optimal xmit_more support, and avoid useless atomic operations as shown in the following patch.

net: fix generic XDP to handle if eth header was mangled
[ Upstream commit 2972495699320229b55b8e5065a310be5c81485b ]
XDP can modify (and resize) the Ethernet header in the packet.
There is a bug in generic-XDP, because skb->protocol and skb->pkt_type
are setup before reaching (netif_receive_)generic_xdp.
This bug was hit when XDP were popping VLAN headers (changing
eth->h_proto), as skb->protocol still contains VLAN-indication
(ETH_P_8021Q) causing invocation of skb_vlan_untag(skb), which corrupt
the packet (basically popping the VLAN again).
This patch catch if XDP changed eth header in such a way, that SKB
fields needs to be updated.
V2: on request from Song Liu, use ETH_HLEN instead of mac_len,
in __skb_push() as eth_type_trans() use ETH_HLEN in paired skb_pull_inline().

netns: fix GFP flags in rtnl_net_notifyid()
[ Upstream commit d4e4fdf9e4a27c87edb79b1478955075be141f67 ]
In rtnl_net_notifyid(), we certainly can't pass a null GFP flag to
rtnl_notify(). A GFP_KERNEL flag would be fine in most circumstances,
but there are a few paths calling rtnl_net_notifyid() from atomic
context or from RCU critical sections. The later also precludes the use
of gfp_any() as it wouldn't detect the RCU case. Also, the nlmsg_new()
call is wrong too, as it uses GFP_KERNEL unconditionally.
Therefore, we need to pass the GFP flags as parameter and propagate it
through function calls until the proper flags can be determined.
In most cases, GFP_KERNEL is fine. The exceptions are:
* openvswitch: ovs_vport_cmd_get() and ovs_vport_cmd_dump()
indirectly call rtnl_net_notifyid() from RCU critical section,
* rtnetlink: rtmsg_ifinfo_build_skb() already receives GFP flags as
parameter.
Also, in ovs_vport_cmd_build_info(), let's change the GFP flags used
by nlmsg_new(). The function is allowed to sleep, so better make the
flags consistent with the ones used in the following
ovs_vport_cmd_fill_info() call.
Found by code inspection.

net: Fix null de-reference of device refcount
[ Upstream commit 10cc514f451a0f239aa34f91bc9dc954a9397840 ]
In event of failure during register_netdevice, free_netdev is
invoked immediately. free_netdev assumes that all the netdevice
refcounts have been dropped prior to it being called and as a
result frees and clears out the refcount pointer.
However, this is not necessarily true as some of the operations
in the NETDEV_UNREGISTER notifier handlers queue RCU callbacks for
invocation after a grace period. The IPv4 callback in_dev_rcu_put
tries to access the refcount after free_netdev is called which
leads to a null de-reference-

jump_label: move 'asm goto' support test to Kconfig
commit e9666d10a5677a494260d60d1fa0b73cc7646eb3 upstream. Currently, CONFIG_JUMP_LABEL just means "I _want_ to use jump label". The jump label is controlled by HAVE_JUMP_LABEL, which is defined like this: #if defined(CC_HAVE_ASM_GOTO) && defined(CONFIG_JUMP_LABEL) # define HAVE_JUMP_LABEL #endif We can improve this by testing 'asm goto' support in Kconfig, then make JUMP_LABEL depend on CC_HAS_ASM_GOTO. Ugly #ifdef HAVE_JUMP_LABEL will go away, and CONFIG_JUMP_LABEL will match to the real kernel capability.
