It triggers NULL pointer dereference when 'neigh->dev->dev_addr' is
called in the rose_send_frame(). It's the first occurrence of the
`neigh` is in rose_loopback_timer() as `rose_loopback_neigh', and
the 'dev' in 'rose_loopback_neigh' is initialized sa nullptr.
It had been fixed by commit 3b3fd068c56e3fbea30090859216a368398e39bf
("rose: Fix Null pointer dereference in rose_send_frame()") ever.
But it's introduced by commit 3c53cd65dece47dd1f9d3a809f32e59d1d87b2b8
("rose: check NULL rose_loopback_neigh->loopback") again.
We fix it by add NULL check in rose_transmit_clear_request(). When
the 'dev' in 'neigh' is NULL, we don't reply the request and just
clear it.
syzkaller don't provide repro, and I provide a syz repro like:
r0 = syz_init_net_socket$bt_sco(0x1f, 0x5, 0x2)
ioctl$sock_inet_SIOCSIFFLAGS(r0, 0x8914, &(0x7f0000000180)={'rose0\x00', 0x201})
r1 = syz_init_net_socket$rose(0xb, 0x5, 0x0)

When using bpftool to pin {PROG, MAP, LINK} without FILE,
segmentation fault will occur. The reson is that the lack
of FILE will cause strlen to trigger NULL pointer dereference.
The corresponding stacktrace is shown below:
do_pin
do_pin_any
do_pin_fd
mount_bpffs_for_pin
strlen(name) <- NULL pointer dereference
Fix it by adding validation to the common process.

In nf_nat_init(), register_nf_nat_bpf() can fail and return directly
without any error handling.
Then nf_nat_bysource will leak and registering of &nat_net_ops,
&follow_master_nat and nf_nat_hook won't be reverted.
This leaves wild ops in linkedlists and when another module tries to
call register_pernet_operations() or nf_ct_helper_expectfn_register()
it triggers page fault:

When device is running and the interface status is changed, the gpf issue
is triggered. The problem triggering process is as follows:
Thread A: Thread B
ieee80211_runtime_change_iftype() process_one_work()
... ...
ieee80211_do_stop() ...
... ...
sdata->bss = NULL ...
... ieee80211_subif_start_xmit()
ieee80211_multicast_to_unicast
//!sdata->bss->multicast_to_unicast
cause gpf issue
When the interface status is changed, the sending queue continues to send
packets. After the bss is set to NULL, the bss is accessed. As a result,
this causes a general-protection-fault issue.
The following is the stack information:

Jakub reported that the addition of the "network_byte_order"
member in struct nla_policy increases size of 32bit platforms.
Instead of scraping the bit from elsewhere Johannes suggested
to add explicit NLA_BE types instead, so do this here.
NLA_POLICY_MAX_BE() macro is removed again, there is no need
for it: NLA_POLICY_MAX(NLA_BE.., ..) will do the right thing.
NLA_BE64 can be added later.

When lan966x was receiving a frame, then it was building the skb and
after that it was calling dma_unmap_single with frame size as the
length. This actually has 2 issues:
1. It is using a length to map and a different length to unmap.
2. When the unmap was happening, the data was sync for cpu but it could
be that this will overwrite what build_skb was initializing.
The fix for these two problems is to change the order of operations.
First to sync the frame for cpu, then to build the skb and in the end to
unmap using the correct size but without sync the frame again for cpu.

Horatiu Vultur says:
====================
net: lan966x: Fixes for when MTU is changed
There were multiple problems in different parts of the driver when
the MTU was changed.
The first problem was that the HW was missing to configure the correct
value, it was missing ETH_HLEN and ETH_FCS_LEN. The second problem was
when vlan filtering was enabled/disabled, the MRU was not adjusted
corretly. While the last issue was that the FDMA was calculated wrongly
the correct maximum MTU.

When MTU is changed, FDMA is required to calculate what is the maximum
size of the frame that it can received. So it can calculate what is the
page order needed to allocate for the received frames.
The first problem was that, when the max MTU was calculated it was
reading the value from dev and not from HW, so in this way it was
missing L2 header + the FCS.
The other problem was that once the skb is created using
__build_skb_around, it would reserve some space for skb_shared_info.
So if we received a frame which size is at the limit of the page order
then the creating will failed because it would not have space to put all
the data.

When vlan filtering is enabled/disabled, it is required to adjust the
maximum received frame size that it can received. When vlan filtering is
enabled, it would all to receive extra 4 bytes, that are the vlan tag.
So the maximum frame size would be 1522 with a vlan tag. If vlan
filtering is disabled then the maximum frame size would be 1518
regardless if there is or not a vlan tag.

When the MTU was changed, the lan966x didn't take in consideration
the L2 header and the FCS. So the HW was configured with a smaller
value than what was desired. Therefore the correct value to configure
the HW would be new_mtu + ETH_HLEN + ETH_FCS_LEN.
The vlan tag is not considered here, because at the time when the
blamed commit was added, there was no vlan filtering support. The
vlan fix will be part of the next patch.

were setting their allocation pointers to NULL, but on error krealloc()
does not touch the original allocation. This would result in a memory

commit release path is invoked via call_rcu and it runs lockless to
release the objects after rcu grace period. The netlink notifier handler
might win race to remove objects that the transaction context is still
referencing from the commit release path.
Call rcu_barrier() to ensure pending rcu callbacks run to completion
if the list of transactions to be destroyed is not empty.

This patch fixes an intra-object buffer overflow in brcmfmac that occurs
when the device provides a 'bsscfgidx' equal to or greater than the
buffer size. The patch adds a check that leads to a safe failure if that
is the case.
This fixes CVE-2022-3628.

With char becoming unsigned by default, and with `char` alone being
ambiguous and based on architecture, we get a warning when assigning the
unchecked output of hex_to_bin() to that unsigned char. Mark `key` as a
`u8`, which matches the struct's type, and then check each call to
hex_to_bin() before casting.

On 32-bit kernels, 64-bit syscall arguments are split into two
registers. For that to work with syscall wrappers, the prototype of the
syscall must have the argument split so that the wrapper macro properly
unpacks the arguments from pt_regs.
The fanotify_mark() syscall is one such syscall, which already has a
split prototype, guarded behind ARCH_SPLIT_ARG64.
So select ARCH_SPLIT_ARG64 to get that prototype and fix fanotify_mark()
on 32-bit kernels with syscall wrappers.
Note also that fanotify_mark() is the only usage of ARCH_SPLIT_ARG64.

Recently, we got two syzkaller problems because of oversize packet
when napi frags enabled.
One of the problems is because the first seg size of the iov_iter
from user space is very big, it is 2147479538 which is bigger than
the threshold value for bail out early in __alloc_pages(). And
skb->pfmemalloc is true, __kmalloc_reserve() would use pfmemalloc
reserves without __GFP_NOWARN flag. Thus we got a warning as following:
========================================================
WARNING: CPU: 1 PID: 17965 at mm/page_alloc.c:5295 __alloc_pages+0x1308/0x16c4 mm/page_alloc.c:5295

tun_chr_write_iter+0x98/0x100 drivers/net/tun.c:2036
The other problem is because odd IPv6 packets without NEXTHDR_NONE
extension header and have big packet length, it is 2127925 which is
bigger than ETH_MAX_MTU(65535). After ipv6_gso_pull_exthdrs() in
ipv6_gro_receive(), network_header offset and transport_header offset
are all bigger than U16_MAX. That would trigger skb->network_header
and skb->transport_header overflow error, because they are all '__u16'
type. Eventually, it would affect the value for __skb_push(skb, value),
and make it be a big value. After __skb_push() in ipv6_gro_receive(),
skb->data would less than skb->head, an out of bounds memory bug occurred.
That would trigger the problem as following:

To fix the problems, restrict the packet size less than
(ETH_MAX_MTU - NET_SKB_PAD - NET_IP_ALIGN) which has considered reserved
skb space in napi_alloc_skb() because transport_header is an offset from
skb->head. Add len check in tun_napi_alloc_frags() simply.

nfc: Fix potential memory leak of skb
There are 6 kinds of send functions can be called by nci_send_frame():
virtual_nci_send(),
fdp_nci_send(),
nxp_nci_send(),
s3fwrn5_nci_send(),
nfcmrvl_nci_send(),
st_nci_send();
1. virtual_nci_send() will memleak the skb, and has been fixed before.
2. fdp_nci_send() won't free the skb no matter whether write() succeed.
3-4. nxp_nci_send() and s3fwrn5_nci_send() will only free the skb when
write() failed, however write() will not free the skb by itself for when
succeeds.
5. nfcmrvl_nci_send() will call nfcmrvl_XXX_nci_send(), where some of
them will free the skb, but nfcmrvl_i2c_nci_send() only free the skb
when i2c_master_send() return >=0, and memleak will happen when
i2c_master_send() failed in nfcmrvl_i2c_nci_send().
6. st_nci_send() will queue the skb into other list and finally be
freed.
