commit 3db152093efb750bc47fd4d69355b90b18113105 upstream.
The batadv_orig_node_vlan reference counter in batadv_tt_global_size_mod
can only be reduced when the list entry was actually removed. Otherwise the
reference counter may reach zero when batadv_tt_global_size_mod is called
from two different contexts for the same orig_node_vlan but only one
context is actually removing the entry from the list.
The release function for this orig_node_vlan is not called inside the
vlan_list_lock spinlock protected region because the function
batadv_tt_global_size_mod still holds a orig_node_vlan reference for the
object pointer on the stack. Thus the actual release function (when
required) will be called only at the end of the function.

commit c18bdd018e8912ca73ad6c12120b7283b5038875 upstream.
The batadv_gw_node reference counter in batadv_gw_node_update can only be
reduced when the list entry was actually removed. Otherwise the reference
counter may reach zero when batadv_gw_node_update is called from two
different contexts for the same gw_node but only one context is actually
removing the entry from the list.
The release function for this gw_node is not called inside the list_lock
spinlock protected region because the function batadv_gw_node_update still
holds a gw_node reference for the object pointer on the stack. Thus the
actual release function (when required) will be called only at the end of
the function.

commit 13bbdd370f67aef3351ad7bbc2fb624e3c23f905 upstream.
batadv_iv_ogm_orig_del_if removes a part of the bcast_own which previously
belonged to the now removed interface. This is done by copying all data
which comes before the removed interface and then appending all the data
which comes after the removed interface.
The address calculation for the position of the data which comes after the
removed interface assumed that the bat_iv.bcast_own is a pointer to a
single byte datatype. But it is a pointer to unsigned long and thus the
calculated position was wrong off factor sizeof(unsigned long).

commit b6f6118901d1e867ac9177bbff3b00b185bd4fdc upstream.
IPV6_ADDRFORM is able to transform IPv6 socket to IPv4 one.
While this operation sounds illogical, we have to support it.
One of the things it does for TCP socket is to switch sk->sk_prot
to tcp_prot.
We now have other layers playing with sk->sk_prot, so we should make
sure to not interfere with them.
This patch makes sure sk_prot is the default pointer for TCP IPv6 socket.

commit 3a20773beeeeadec41477a5ba872175b778ff752 upstream.
Since nl_groups is a u32 we can't bind more groups via ->bind
(netlink_bind) call, but netlink has supported more groups via
setsockopt() for a long time and thus nlk->ngroups could be over 32.
Recently I added support for per-vlan notifications and increased the
groups to 33 for NETLINK_ROUTE which exposed an old bug in the
netlink_bind() code causing out-of-bounds access on archs where unsigned
long is 32 bits via test_bit() on a local variable. Fix this by capping the
maximum groups in netlink_bind() to BITS_PER_TYPE(u32), effectively
capping them at 32 which is the minimum of allocated groups and the
maximum groups which can be bound via netlink_bind().

[ Upstream commit 8a9093c79863b58cc2f9874d7ae788f0d622a596 ]
tc flower rules that are based on src or dst port blocking are sometimes
ineffective due to uninitialized stack data. __skb_flow_dissect() extracts
ports from the skb for tc flower to match against. However, the port
dissection is not done when when the FLOW_DIS_IS_FRAGMENT bit is set in
key_control->flags. All callers of __skb_flow_dissect(), zero-out the
key_control field except for fl_classify() as used by the flower
classifier. Thus, the FLOW_DIS_IS_FRAGMENT may be set on entry to
__skb_flow_dissect(), since key_control is allocated on the stack
and may not be initialized.
Since key_basic and key_control are present for all flow keys, let's
make sure they are initialized.
Fixes: 62230715fd24 ("flow_dissector: do not dissect l4 ports for fragments")

[ Upstream commit 245709ec8be89af46ea7ef0444c9c80913999d99 ]
When T2 timer is to be stopped, the asoc should also be deleted,
otherwise, there will be no chance to call sctp_association_free
and the asoc could last in memory forever.
However, in sctp_sf_shutdown_sent_abort(), after adding the cmd
SCTP_CMD_TIMER_STOP for T2 timer, it may return error due to the
format error from __sctp_sf_do_9_1_abort() and miss adding
SCTP_CMD_ASSOC_FAILED where the asoc will be deleted.
This patch is to fix it by moving the format error check out of
__sctp_sf_do_9_1_abort(), and do it before adding the cmd
SCTP_CMD_TIMER_STOP for T2 timer.
Thanks Hangbin for reporting this issue by the fuzz testing.
v1->v2:
- improve the comment in the code as Marcelo's suggestion.

[ Upstream commit e404b8c7cfb31654c9024d497cec58a501501692 ]
After commit 27596472473a ("ipv6: fix ECMP route replacement") it is no
longer possible to replace an ECMP-able route by a non ECMP-able route.
For example,
ip route add 2001:db8::1/128 via fe80::1 dev dummy0
ip route replace 2001:db8::1/128 dev dummy0
does not work as expected.
Tweak the replacement logic so that point 3 in the log of the above commit
becomes:
3. If the new route is not ECMP-able, and no matching non-ECMP-able route
exists, replace matching ECMP-able route (if any) or add the new route.
We can now summarize the entire replace semantics to:
When doing a replace, prefer replacing a matching route of the same
"ECMP-able-ness" as the replace argument. If there is no such candidate,
fallback to the first route found.

[ Upstream commit afecdb376bd81d7e16578f0cfe82a1aec7ae18f3 ]
When splitting an RTA_MULTIPATH request into multiple routes and adding the
second and later components, we must not simply remove NLM_F_REPLACE but
instead replace it by NLM_F_CREATE. Otherwise, it may look like the netlink
message was malformed.
For example,
ip route add 2001:db8::1/128 dev dummy0
ip route change 2001:db8::1/128 nexthop via fe80::30:1 dev dummy0 \
nexthop via fe80::30:2 dev dummy0
results in the following warnings:
[ 1035.057019] IPv6: RTM_NEWROUTE with no NLM_F_CREATE or NLM_F_REPLACE
[ 1035.057517] IPv6: NLM_F_CREATE should be set when creating new route
This patch makes the nlmsg sequence look equivalent for __ip6_ins_rt() to
what it would get if the multipath route had been added in multiple netlink
operations:
ip route add 2001:db8::1/128 dev dummy0
ip route change 2001:db8::1/128 nexthop via fe80::30:1 dev dummy0
ip route append 2001:db8::1/128 nexthop via fe80::30:2 dev dummy0

[ Upstream commit a04564c99bb4a92f805a58e56b2d22cc4978f152 ]
We only use the parsing CRC for checking if a beacon changed,
and elements with an ID > 63 cannot be represented in the
filter. Thus, like we did before with WMM and Cisco vendor
elements, just statically add these forgotten items to the
CRC:
- WLAN_EID_VHT_OPERATION
- WLAN_EID_OPMODE_NOTIF
I guess that in most cases when VHT/HE operation change, the HT
operation also changed, and so the change was picked up, but we
did notice that pure operating mode notification changes were
ignored.

[ Upstream commit 6ab405114b0b229151ef06f4e31c7834dd09d0c0 ]
Check whether inputs from userspace are too long (explicit length field too
big or string not null-terminated) to avoid out-of-bounds reads.
As far as I can tell, this can at worst lead to very limited kernel heap
memory disclosure or oopses.
This bug can be triggered by an unprivileged user even if the xt_bpf module
is not loaded: iptables is available in network namespaces, and the xt_bpf
module can be autoloaded.
Triggering the bug with a classic BPF filter with fake length 0x1000 causes
the following KASAN report:

commit 3d96208c30f84d6edf9ab4fac813306ac0d20c10 upstream.
When upcalling gssproxy, cache_head.expiry_time is set as a
timeval, not seconds since boot. As such, RPC cache expiry
logic will not clean expired objects created under
auth.rpcsec.context cache.
This has proven to cause kernel memory leaks on field. Using
64 bit variants of getboottime/timespec
Expiration times have worked this way since 2010's c5b29f885afe "sunrpc:
use seconds since boot in expiry cache". The gssproxy code introduced
in 2012 added gss_proxy_save_rsc and introduced the bug. That's a while
for this to lurk, but it required a bit of an extreme case to make it
obvious.

[ Upstream commit 599be01ee567b61f4471ee8078870847d0a11e8e ]
As Eric noticed, tcindex_alloc_perfect_hash() uses cp->hash
to compute the size of memory allocation, but cp->hash is
set again after the allocation, this caused an out-of-bound
access.
So we have to move all cp->hash initialization and computation
before the memory allocation. Move cp->mask and cp->shift together
as cp->hash may need them for computation too.

[ Upstream commit cb3c0e6bdf64d0d124e94ce43cbe4ccbb9b37f51 ]
NLA_BINARY can be confusing, since .len value represents
the max size of the blob.
cls_rsvp really wants user space to provide long enough data
for TCA_RSVP_DST and TCA_RSVP_SRC attributes.

[ Upstream commit 189c9b1e94539b11c80636bc13e9cf47529e7bba ]
skb->csum is updated incorrectly, when manipulation for
NF_NAT_MANIP_SRC\DST is done on IPV6 packet.
Fix:
There is no need to update skb->csum in inet_proto_csum_replace16(),
because update in two fields a.) IPv6 src/dst address and b.) L4 header
checksum cancels each other for skb->csum calculation. Whereas
inet_proto_csum_replace4 function needs to update skb->csum, because
update in 3 fields a.) IPv4 src/dst address, b.) IPv4 Header checksum
and c.) L4 header checksum results in same diff as L4 Header checksum
for skb->csum calculation.

[ Upstream commit 95224166a9032ff5d08fca633d37113078ce7d01 ]
With an ebpf program that redirects packets through a vti[6] interface,
the packets are dropped because no dst is attached.
This could also be reproduced with an AF_PACKET socket, with the following
python script (vti1 is an ip_vti interface):
import socket
send_s = socket.socket(socket.AF_PACKET, socket.SOCK_RAW, 0)
# scapy
# p = IP(src='10.100.0.2', dst='10.200.0.1')/ICMP(type='echo-request')
# raw(p)
req = b'E\x00\x00\x1c\x00\x01\x00\x00@\x01e\xb2\nd\x00\x02\n\xc8\x00\x01\x08\x00\xf7\xff\x00\x00\x00\x00'
send_s.sendto(req, ('vti1', 0x800, 0, 0))

[ Upstream commit e16119655c9e6c4aa5767cd971baa9c491f41b13 ]
After the introduction of CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3,
the wext code produces a bogus warning:
In function 'iw_handler_get_iwstats',
inlined from 'ioctl_standard_call' at net/wireless/wext-core.c:1015:9,
inlined from 'wireless_process_ioctl' at net/wireless/wext-core.c:935:10,
inlined from 'wext_ioctl_dispatch.part.8' at net/wireless/wext-core.c:986:8,
inlined from 'wext_handle_ioctl':
net/wireless/wext-core.c:671:3: error: argument 1 null where non-null expected [-Werror=nonnull]
memcpy(extra, stats, sizeof(struct iw_statistics));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from arch/x86/include/asm/string.h:5,
net/wireless/wext-core.c: In function 'wext_handle_ioctl':
arch/x86/include/asm/string_64.h:14:14: note: in a call to function 'memcpy' declared here
The problem is that ioctl_standard_call() sometimes calls the handler
with a NULL argument that would cause a problem for iw_handler_get_iwstats.
However, iw_handler_get_iwstats never actually gets called that way.
Marking that function as noinline avoids the warning and leads
to slightly smaller object code as well.

[ Upstream commit 55cd9f67f1e45de8517cdaab985fb8e56c0bc1d8 ]
It is possible for malicious userspace to set TCF_EM_SIMPLE bit
even for matches that should not have this bit set.
This can fool two places using tcf_em_is_simple()
1) tcf_em_tree_destroy() -> memory leak of em->data
if ops->destroy() is NULL
2) tcf_em_tree_dump() wrongly report/leak 4 low-order bytes
of a kernel pointer.

commit e21dba7a4df4d93da237da65a096084b4f2e87b4 upstream.
This patch fixes 2 issues in x25_connect():
1. It makes absolutely no sense to reset the neighbour and the
connection state after a (successful) nonblocking call of x25_connect.
This prevents any connection from being established, since the response
(call accept) cannot be processed.
2. Any further calls to x25_connect() while a call is pending should
simply return, instead of creating new Call Request (on different
logical channels).
This patch should also fix the "KASAN: null-ptr-deref Write in
x25_connect" and "BUG: unable to handle kernel NULL pointer dereference
in x25_connect" bugs reported by syzbot.

commit 32c72165dbd0e246e69d16a3ad348a4851afd415 upstream.
The bitmap allocation did not use full unsigned long sizes
when calculating the required size and that was triggered by KASAN
as slab-out-of-bounds read in several places. The patch fixes all
of them.

[ Upstream commit 61678d28d4a45ef376f5d02a839cc37509ae9281 ]
syzbot reported an out-of-bound access in em_nbyte. As initially
analyzed by Eric, this is because em_nbyte sets its own em->datalen
in em_nbyte_change() other than the one specified by user, but this
value gets overwritten later by its caller tcf_em_validate().
We should leave em->datalen untouched to respect their choices.
I audit all the in-tree ematch users, all of those implement
->change() set em->datalen, so we can just avoid setting it twice
in this case.

[ Upstream commit d0f418516022c32ecceaf4275423e5bd3f8743a9 ]
in the same manner as commit 690afc165bb3 ("net: ip6_gre: fix moving
ip6gre between namespaces"), fix namespace moving as it was broken since
commit 2e15ea390e6f ("ip_gre: Add support to collect tunnel metadata.").
Indeed, the ip6_gre commit removed the local flag for collect_md
condition, so there is no reason to keep it for ip_gre/ip_tunnel.
this patch will fix both ip_tunnel and ip_gre modules.
Fixes: 2e15ea390e6f ("ip_gre: Add support to collect tunnel metadata.")

[ Upstream commit b756ad928d98e5ef0b74af7546a6a31a8dadde00 ]
KCSAN reported the following data-race [1]
Adding a couple of READ_ONCE()/WRITE_ONCE() should silence it.
Since the report hinted about multiple cpus using the history
concurrently, I added a test avoiding writing on it if the
victim slot already contains the desired value.

[ Upstream commit 36453c852816f19947ca482a595dffdd2efa4965 ]
If llc_conn_state_process() sees that llc_conn_service() put the skb on
a list, it will drop one fewer references to it. This is wrong because
the current behavior is that llc_conn_service() never consumes a
reference to the skb.
The code also makes the number of skb references being dropped
conditional on which of ind_prim and cfm_prim are nonzero, yet neither
of these affects how many references are *acquired*. So there is extra
code that tries to fix this up by sometimes taking another reference.
Remove the unnecessary/broken refcounting logic and instead just add an
skb_get() before the only two places where an extra reference is
actually consumed.

[ Upstream commit fc8d5db10cbe1338a52ebc74e7feab9276721774 ]
All callers of llc_conn_state_process() except llc_build_and_send_pkt()
(via llc_ui_sendmsg() -> llc_ui_send_data()) assume that it always
consumes a reference to the skb. Fix this caller to do the same.
