net: hns3: fix VF wrong speed and duplex issue
If PF is down, firmware will returns 10 Mbit/s rate and half-duplex mode
when PF queries the port information from firmware.
After imp reset command is executed, PF status changes to down,
and PF will query link status and updates port information
from firmware in a periodic scheduled task.
However, there is a low probability that port information is updated
when PF is down, and then PF link status changes to up.
In this case, PF synchronizes incorrect rate and duplex mode to VF.
This patch fixes it by updating port information before
PF synchronizes the rate and duplex to the VF
when PF changes to up.

net: hns3: fix VF reset fail issue
Currently the reset process in hns3 and firmware watchdog init process is
asynchronous. We think firmware watchdog initialization is completed
before VF clear the interrupt source. However, firmware initialization
may not complete early. So VF will receive multiple reset interrupts
and fail to reset.
So we add delay before VF interrupt source and 5 ms delay
is enough to avoid second reset interrupt.

net: hns3: fix variable may not initialized problem in hns3_init_mac_addr()
When a VF is calling hns3_init_mac_addr(), get_mac_addr() may
return fail, then the value of mac_addr_temp is not initialized.

net: hns3: fix out-of-bounds access may occur when coalesce info is read via debugfs
The hns3 driver define an array of string to show the coalesce
info, but if the kernel adds a new mode or a new state,
out-of-bounds access may occur when coalesce info is read via
debugfs, this patch fix the problem.

net: hns3: fix incorrect capability bit display for copper port
Currently, the FEC capability bit is default set for device version V2.
It's incorrect for the copper port. Eventhough it doesn't make the nic
work abnormal, but the capability information display in debugfs may
confuse user. So clear it when driver get the port type inforamtion.

net: hns3: add barrier in vf mailbox reply process
In hclgevf_mbx_handler() and hclgevf_get_mbx_resp() functions,
there is a typical store-store and load-load scenario between
received_resp and additional_info. This patch adds barrier
to fix the problem.

net: hns3: fix add VLAN fail issue
The hclge_sync_vlan_filter is called in periodic task,
trying to remove VLAN from vlan_del_fail_bmap. It can
be concurrence with VLAN adding operation from user.
So once user failed to delete a VLAN id, and add it
again soon, it may be removed by the periodic task,
which may cause the software configuration being
inconsistent with hardware. So add mutex handling
to avoid this.

=====================================================
ppp_sync_input() checks the first 2 bytes of the data are PPP_ALLSTATIONS
and PPP_UI. However, if the data length is 1 and the first byte is
PPP_ALLSTATIONS, an access to an uninitialized value occurs when checking
PPP_UI. This patch resolves this issue by checking the data length.

ipvlan: add ipvlan_route_v6_outbound() helper
Inspired by syzbot reports using a stack of multiple ipvlan devices.
Reduce stack size needed in ipvlan_process_v6_outbound() by moving
the flowi6 struct used for the route lookup in an non inlined
helper. ipvlan_route_v6_outbound() needs 120 bytes on the stack,
immediately reclaimed.
Also make sure ipvlan_process_v4_outbound() is not inlined.
We might also have to lower MAX_NEST_DEV, because only syzbot uses
setups with more than four stacked devices.

__inet_hash can race with lockless (rcu) readers on the other cpus:
__inet_hash
__sk_nulls_add_node_rcu
<- (bpf triggers here)
sock_set_flag(SOCK_RCU_FREE)
Let's move the SOCK_RCU_FREE part up a bit, before we are inserting
the socket into hashtables. Note, that the race is really harmless;
the bpf callers are handling this situation (where listener socket
doesn't have SOCK_RCU_FREE set) correctly, so the only
annoyance is a WARN_ONCE.
More details from Eric regarding SOCK_RCU_FREE timeline:

ptp: Fixes a null pointer dereference in ptp_ioctl
Syzkaller found a null pointer dereference in ptp_ioctl
originating from the lack of a null check for tsevq.

This patch fixes the issue by adding a check for tsevq and
ensuring ptp_ioctl returns with an error if tsevq is null.

net: ti: icss-iep: fix setting counter value
Currently icss_iep_set_counter() writes the upper 32-bits of the
counter value to both the lower and upper counter registers, so
fix this by writing the appropriate value to the lower register.

ptp: fix corrupted list in ptp_open
There is no lock protection when writing ptp->tsevqs in ptp_open() and
ptp_release(), which can cause data corruption, use spin lock to avoid this
issue.
Moreover, ptp_release() should not be used to release the queue in ptp_read(),
and it should be deleted altogether.

ptp: ptp_read should not release queue
Firstly, queue is not the memory allocated in ptp_read;
Secondly, other processes may block at ptp_read and wait for conditions to be
met to perform read operations.

net/sched: act_ct: Always fill offloading tuple iifidx
Referenced commit doesn't always set iifidx when offloading the flow to hardware. Fix the following cases: - nf_conn_act_ct_ext_fill() is called before extension is created with nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with unspecified iifidx when connection is offloaded after only single original-direction packet has been processed by tc data path. Always fill the new nf_conn_act_ct_ext instance after creating it in nf_conn_act_ct_ext_add(). - Offloading of unidirectional UDP NEW connections is now supported, but ct flow iifidx field is not updated when connection is promoted to bidirectional which can result reply-direction iifidx to be zero when refreshing the connection. Fill in the extension and update flow iifidx before calling flow_offload_refresh(). Fixes: |

netfilter: nat: fix ipv6 nat redirect with mapped and scoped addresses
The ipv6 redirect target was derived from the ipv4 one, i.e. its
identical to a 'dnat' with the first (primary) address assigned to the
network interface. The code has been moved around to make it usable
from nf_tables too, but its still the same as it was back when this
was added in 2012.
IPv6, however, has different types of addresses, if the 'wrong' address
comes first the redirection does not work.
In Daniels case, the addresses are:
inet6 ::ffff:192 ...
inet6 2a01: ...
... so the function attempts to redirect to the mapped address.
Add more checks before the address is deemed correct:
1. If the packets' daddr is scoped, search for a scoped address too
2. skip tentative addresses
3. skip mapped addresses
Use the first address that appears to match our needs.
Reported-by: Daniel Huhardeaux <tech@tootai.net>
Closes: https://lore.kernel.org/netfilter/71be06b8-6aa0-4cf9-9e0b-e2839b01b22f@tootai.net/

drivers/net/ppp: use standard array-copy-function
In ppp_generic.c, memdup_user() is utilized to copy a userspace array. This is done without an overflow-check, which is, however, not critical because the multiplicands are an unsigned short and struct sock_filter, which is currently of size 8. Regardless, string.h now provides memdup_array_user(), a wrapper for copying userspace arrays in a standardized manner, which has the advantage of making it more obvious to the reader that an array is being copied. The wrapper additionally performs an obligatory overflow check, saving the reader the effort of analyzing the potential for overflow, and making the code a bit more robust in case of future changes to the multiplicands len * size. Replace memdup_user() with memdup_array_user(). Suggested-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Philipp Stanner <pstanner@redhat.com> Signed-off-by: David S.

i2c: cp2615: Fix 'assignment to __be16' warning
While the preamble field _is_ technically big-endian, its value is always 0x2A2A, which is the same in either endianness. However, to avoid generating a warning, we should still call `htons()` explicitly. Signed-off-by: Bence Csókás <bence98@sch.bme.hu> Signed-off-by: Wolfram Sang <wsa@kernel.org> |

i2c: dev: copy userspace array safely
i2c-dev.c utilizes memdup_user() to copy a userspace array. This is done without an overflow check. Use the new wrapper memdup_array_user() to copy the array more safely.
