"Another round of SPDX header file fixes for 5.2-rc4
These are all more "GPL-2.0-or-later" or "GPL-2.0-only" tags being

these were reviewed on the spdx mailing list by a number of different

Currently, the process issuing a "start" command on the pktgen procfs
interface, acquires the pktgen thread lock and never release it, until
all pktgen threads are completed. The above can blocks indefinitely any
other pktgen command and any (even unrelated) netdevice removal - as
the pktgen netdev notifier acquires the same lock.
The issue is demonstrated by the following script, reported by Matteo:
ip -b - <<'EOF'
link add type dummy
link add type veth
link set dummy0 up
EOF
modprobe pktgen
echo reset >/proc/net/pktgen/pgctrl
{
echo rem_device_all
echo add_device dummy0
} >/proc/net/pktgen/kpktgend_0
echo count 0 >/proc/net/pktgen/dummy0
echo start >/proc/net/pktgen/pgctrl &
sleep 1
rmmod veth
Fix the above releasing the thread lock around the sleep call.
Additionally we must prevent racing with forcefull rmmod - as the
thread lock no more protects from them. Instead, acquire a self-reference
before waiting for any thread. As a side effect, running
rmmod pktgen
while some thread is running now fails with "module in use" error,
before this patch such command hanged indefinitely.
Note: the issue predates the commit reported in the fixes tag, but
this fix can't be applied before the mentioned commit.
v1 -> v2:
- no need to check for thread existence after flipping the lock,
pktgen threads are freed only at net exit time
-

When ibmr_ret is NULL, llist_entry is not executed. clean_nodes->next
instead of clean_nodes is added in clean_list.
So clean_nodes is discarded. It can not be used again.
The workqueue is executed periodically. So more and more clean_nodes are
discarded. Finally the clean_list is NULL.

The following code returns EFAULT (Bad address):
s = socket(AF_INET6, SOCK_RAW, IPPROTO_ICMPV6);
setsockopt(s, SOL_IPV6, IPV6_HDRINCL, 1);
sendto(ipv6_icmp6_packet, addr); /* returns -1, errno = EFAULT */
The IPv4 equivalent code works. A workaround is to use IPPROTO_RAW
instead of IPPROTO_ICMPV6.
The failure happens because 2 bytes are eaten from the msghdr by
rawv6_probe_proto_opt() starting from commit 19e3c66b52ca ("ipv6
equivalent of "ipv4: Avoid reading user iov twice after
raw_probe_proto_opt""), but at that time it was not a problem because
IPV6_HDRINCL was not yet introduced.
Only eat these 2 bytes if hdrincl == 0.

NLM_F_EXCL not supplied"
This reverts commit e9919a24d3022f72bcadc407e73a6ef17093a849.
Nathan reported the new behaviour breaks Android, as Android just add
new rules and delete old ones.
If we return 0 without adding dup rules, Android will remove the new
added rules and causing system to soft-reboot.

ethtool_get_regs() allocates a buffer of size ops->get_regs_len(),
and pass it to the kernel driver via ops->get_regs() for filling.
There is no restriction about what the kernel drivers can or cannot do
with the open ethtool_regs structure. They usually set regs->version
and ignore regs->len or set it to the same size as ops->get_regs_len().
But if userspace allocates a smaller buffer for the registers dump,
we would cause a userspace buffer overflow in the final copy_to_user()
call, which uses the regs.len value potentially reset by the driver.
To fix this, make this case obvious and store regs.len before calling
ops->get_regs(), to only copy as much data as requested by userspace,
up to the value returned by ops->get_regs_len().
While at it, remove the redundant check for non-null regbuf.

The problem was that the peer.cookie value points to an skb allocated
area on the first pass through this function, at which point it is
overwritten with a heap allocated value, but in certain cases, where a
COOKIE_ECHO chunk is included in the packet, a second pass through
sctp_process_init is made, where the cookie value is re-allocated,
leaking the first allocation.
Fix is to always allocate the cookie value, and free it when we are done
using it.

When KASAN is enabled, after several rds connections are
created, then "rmmod rds_rdma" is run. The following will
appear.
"

entry_SYSCALL_64_after_hwframe+0x44/0xa9
"
This is rds connection memory leak. The root cause is:
When "rmmod rds_rdma" is run, rds_ib_remove_one will call
rds_ib_dev_shutdown to drop the rds connections.
rds_ib_dev_shutdown will call rds_conn_drop to drop rds
connections as below.
"
rds_conn_path_drop(&conn->c_path[0], false);
"
In the above, destroy is set to false.
void rds_conn_path_drop(struct rds_conn_path *cp, bool destroy)
{
atomic_set(&cp->cp_state, RDS_CONN_ERROR);
rcu_read_lock();
if (!destroy && rds_destroy_pending(cp->cp_conn)) {
rcu_read_unlock();
return;
}
queue_work(rds_wq, &cp->cp_down_w);
rcu_read_unlock();
}
In the above function, destroy is set to false. rds_destroy_pending
is called. This does not move rds connections to ib_nodev_conns.
So destroy is set to true to move rds connections to ib_nodev_conns.
In rds_ib_unregister_client, flush_workqueue is called to make rds_wq
finsh shutdown rds connections. The function rds_ib_destroy_nodev_conns
is called to shutdown rds connections finally.
Then rds_ib_recv_exit is called to destroy slab.
void rds_ib_recv_exit(void)
{
kmem_cache_destroy(rds_ib_incoming_slab);
kmem_cache_destroy(rds_ib_frag_slab);
}
The above slab memory leak will not occur again.

[root@ca-dev14 ~]# time rmmod rds_rdma
real 0m32.054s
user 0m0.000s
sys 0m15.568s
To rmmod rds_rdma with 256 rds connections, about 16 seconds are needed.
And with 512 rds connections, about 32 seconds are needed.
>From ftrace, when one rds connection is destroyed,
"

15) | rds_shutdown_worker [rds]() {
15) | rds_conn_shutdown [rds]() {
15) 1.651 us | rds_send_path_reset [rds]();
15) 7.195 us | }
15) + 11.434 us | }
19) 2.285 us | rds_cong_remove_conn [rds]();
19) * 24062.76 us | }
"
So if many rds connections will be destroyed, this function
rds_ib_destroy_nodev_conns uses most of time.

With the topo:
h1 ---| rp1 |
| route rp3 |--- h3 (192.168.200.1)
h2 ---| rp2 |
If rp1 bc_forwarding is set while rp2 bc_forwarding is not, after
doing "ping 192.168.200.255" on h1, then ping 192.168.200.255 on
h2, and the packets can still be forwared.
This issue was caused by the input route cache. It should only do
the cache for either bc forwarding or local delivery. Otherwise,
local delivery can use the route cache for bc forwarding of other
interfaces.
This patch is to fix it by not doing cache for local delivery if
all.bc_forwarding is enabled.
Note that we don't fix it by checking route cache local flag after
rt_cache_valid() in "local_input:" and "ip_mkroute_input", as the
common route code shouldn't be touched for bc_forwarding.
Fixes: 5cbf777cfdf6 ("route: add support for directed broadcast forwarding")

As Eric noted, the current wrapper for ptype func hook inside
__netif_receive_skb_list_ptype() has no chance of avoiding the indirect
call: we enter such code path only for protocols other than ipv4 and
ipv6.
Instead we can wrap the list_func invocation.
v1 -> v2:
- use the correct fix tag

By default, packets received in another VRF should not be passed to an
unbound socket in the default VRF. This patch updates the IPv4 UDP
multicast logic to match the unicast VRF logic (in compute_score()),
as well as the IPv6 mcast logic (in __udp_v6_is_mcast_sock()).
The particular case I noticed was DHCP discover packets going
to the 255.255.255.255 address, which are handled by
__udp4_lib_mcast_deliver(). The previous code meant that running
multiple different DHCP server or relay agent instances across VRFs
did not work correctly - any server/relay agent in the default VRF
received DHCP discover packets for all other VRFs.

Commit 38030d7cb779 ("net/tls: avoid NULL-deref on resync during device removal")
tried to fix a potential NULL-dereference by taking the
context rwsem. Unfortunately the RX resync may get called
from soft IRQ, so we can't use the rwsem to protect from
the device disappearing. Because we are guaranteed there
can be only one resync at a time (it's called from strparser)
use a bit to indicate resync is busy and make device
removal wait for the bit to get cleared.
Note that there is a leftover "flags" field in struct
tls_context already.

Rollover used to use a complex RCU mechanism for assignment, which had
a race condition. The below patch fixed the bug and greatly simplified
the logic.
The feature depends on fanout, but the state is private to the socket.
Fanout_release returns f only when the last member leaves and the
fanout struct is to be freed.
Destroy rollover unconditionally, regardless of fanout state.
