One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count,
GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
Notice that, currently, there is a bug during the allocation:
sizeof(npcm7xx_clk_data) should be sizeof(*npcm7xx_clk_data)
Fix this bug by using struct_size() in kzalloc()
This issue was detected with the help of Coccinelle.

Fix the VMC page fault when the running sequence is as below:

2.ttm_bo_swapout->amdgpu_vm_bo_invalidate, as not called
amdgpu_vm_bo_base_init, so won't called
list_add_tail(&base->bo_list, &bo->va). Even the bo was evicted,
it won't set the bo_base->moved.
3.drm_gem_open_ioctl->amdgpu_vm_bo_base_init, here only called
list_move_tail(&base->vm_status, &vm->evicted), but not set the
bo_base->moved.
4.amdgpu_vm_bo_map->amdgpu_vm_bo_insert_map, as the bo_base->moved is
not set true, the function amdgpu_vm_bo_insert_map will call
list_move(&bo_va->base.vm_status, &vm->moved)
5.amdgpu_cs_ioctl won't validate the swapout bo, as it is only in the
moved list, not in the evict list. So VMC page fault occurs.

Otherwise we can get the following errors occasionally on some devices:
mmc1: tried to HW reset card, got error -110
mmcblk1: error -110 requesting status
mmcblk1: recovery failed!
print_req_error: I/O error, dev mmcblk1, sector 14329
...
I have one device that hits this error almost on every boot, and another
one that hits it only rarely with the other ones I've used behave without
problems. I'm not sure if the issue is related to a particular eMMC card
model, but in case it is, both of the machines with issues have:
# cat /sys/class/mmc_host/mmc1/mmc1:0001/manfid \
/sys/class/mmc_host/mmc1/mmc1:0001/oemid \
/sys/class/mmc_host/mmc1/mmc1:0001/name
0x000045
0x0100
SEM16G
and the working ones have:
0x000011
0x0100
016G92
Note that "ti,non-removable" is different as omap_hsmmc_reg_get() does not
call omap_hsmmc_disable_boot_regulators() if no_regulator_off_init is set.
And currently we set no_regulator_off_init only for "ti,non-removable" and
not for "non-removable". It seems that we should have "non-removable" with
some other mmc generic property behave in the same way instead of having to
use a non-generic property. But let's fix the issue first.

So, It can be exploited via Spectre-like attack. (speculative execution)
This kind of attack leaks address of hwsim_world_regdom_custom,
It leads an attacker to bypass security mechanism such as KASLR.
So sanitize @idx before using it to prevent attack.

I changed the way mac80211 updates the PM state of the peer.
I forgot that we could also have multicast frames from the
peer and that those frame should of course not change the
PM state of the peer: A peer goes to power save when it
needs to scan, but it won't send the broadcast Probe Request
with the PM bit set.
This made us mark the peer as awake when it wasn't and then
Intel's firmware would fail to transmit because the peer is
asleep according to its database. The driver warned about
this and it looked like this:
WARNING: CPU: 0 PID: 184 at /usr/src/linux-4.16.14/drivers/net/wireless/intel/iwlwifi/mvm/tx.c:1369 iwl_mvm_rx_tx_cmd+0x53b/0x860

Make wmm_rule be part of the reg_rule structure. This simplifies the
code a lot at the cost of having bigger memory usage. However in most
cases we have only few reg_rule's and when we do have many like in
iwlwifi we do not save memory as it allocates a separate wmm_rule for
each channel anyway.
This also fixes a bug reported in various places where somewhere the
pointers were corrupted and we ended up doing a null-dereference.

Currently, when a redirect occurs in sockmap and an error occurs in
the redirect call we unwind the scatterlist once in the error path
of bpf_tcp_sendmsg_do_redirect() and then again in sendmsg(). Then
in the error path of sendmsg we decrement the copied count by the
send size.
However, its possible we partially sent data before the error was
generated. This can happen if do_tcp_sendpages() partially sends the
scatterlist before encountering a memory pressure error. If this
happens we need to decrement the copied value (the value tracking
how many bytes were actually sent to TCP stack) by the number of
remaining bytes _not_ the entire send size. Otherwise we risk
confusing userspace.
Also we don't need two calls to free the scatterlist one is
good enough. So remove the one in bpf_tcp_sendmsg_do_redirect() and
then properly reduce copied by the number of remaining bytes which
may in fact be the entire send size if no bytes were sent.
To do this use bool to indicate if free_start_sg() should do mem
accounting or not.

When a targetport is removed from the config, fcloop will avoid calling
the LS done() routine thinking the targetport is gone. This leaves the
initiator reset/reconnect hanging as it waits for a status on the
Create_Association LS for the reconnect.
Change the filter in the LS callback path. If tport null (set when
failed validation before "sending to remote port"), be sure to call
done. This was the main bug. But, continue the logic that only calls
done if tport was set but there is no remoteport (e.g. case where
remoteport has been removed, thus host doesn't expect a completion).

In many architectures loads may be reordered with older stores to
different locations. In the nvme driver the following two operations
could be reordered:
- Write shadow doorbell (dbbuf_db) into memory.
- Read EventIdx (dbbuf_ei) from memory.
This can result in a potential race condition between driver and VM host
processing requests (if given virtual NVMe controller has a support for
shadow doorbell). If that occurs, then the NVMe controller may decide to
wait for MMIO doorbell from guest operating system, and guest driver may
decide not to issue MMIO doorbell on any of subsequent commands.
This issue is purely timing-dependent one, so there is no easy way to
reproduce it. Currently the easiest known approach is to run "Oracle IO
Numbers" (orion) that is shipped with Oracle DB:
orion -run advanced -num_large 0 -size_small 8 -type rand -simulate \
concat -write 40 -duration 120 -matrix row -testname nvme_test
Where nvme_test is a .lun file that contains a list of NVMe block
devices to run test against. Limiting number of vCPUs assigned to given
VM instance seems to increase chances for this bug to occur. On test
environment with VM that got 4 NVMe drives and 1 vCPU assigned the
virtual NVMe controller hang could be observed within 10-20 minutes.
That correspond to about 400-500k IO operations processed (or about
100GB of IO read/writes).
Orion tool was used as a validation and set to run in a loop for 36
hours (equivalent of pushing 550M IO operations). No issues were
observed. That suggest that the patch fixes the issue.

once we find that there are skbs in the normal socket's receive queue
we return with processing them through tcp_recvmsg(). Problem is that

bpf_tcp_close() we pop the psock linkage to a map via psock_map_pop().
A parallel update on the sock hash map can happen between psock_map_pop()
and lookup_elem_raw() where we override the element under link->hash /
link->key. In bpf_tcp_close()'s lookup_elem_raw() we subsequently only
test whether an element is present, but we do not test whether the
element is infact the element we were looking for.
We lock the sock in bpf_tcp_close() during that time, so do we hold
the lock in sock_hash_update_elem(). However, the latter locks the
sock which is newly updated, not the one we're purging from the hash
table. This means that while one CPU is doing the lookup from bpf_tcp_close(),
another CPU is doing the map update in parallel, dropped our sock from
the hlist and released the psock.
Subsequently the first CPU will find the new sock and attempts to drop
and release the old sock yet another time. Fix is that we need to check
the elements for a match after lookup, similar as we do in the sock map.
Note that the hash tab elems are freed via RCU, so access to their
link->hash / link->key is fine since we're under RCU read side there.

Currently, variable ref_count within the bsg_device struct is of
type atomic_t. For variables being used as reference counters,
the refcount API should be used instead of atomic. The newer

potentially avoiding the issues mentioned.

In IPv4, the newly introduced rdma_read_gids is used to read the SGID/DGID
for the connection which returns GID correctly for RoCE transport as well.
In IPv6, rdma_read_gids is also used. The following are why rdma_read_gids
is introduced.
rdma_addr_get_dgid() for RoCE for client side connections returns MAC
address, instead of DGID.
rdma_addr_get_sgid() for RoCE doesn't return correct SGID for IPv6 and
when more than one IP address is assigned to the netdevice.
So the transport agnostic rdma_read_gids() API is provided by rdma_cm
module.

In function tipc_dest_push, the 32bit variables 'node' and 'port'
are stored separately in uppper and lower part of 64bit 'value'.
Then this value is assigned to dst->value which is a union like:
union
{
struct {
u32 port;
u32 node;
};
u64 value;
}
This works on little-endian machines like x86 but fails on big-endian
machines.
The fix remove the 'value' stack parameter and even the 'value'
member of the union in tipc_dest, assign the 'node' and 'port' member
directly with the input parameter to avoid the endian issue.

When chain 0 was implicitly created, removal of non-existent filter from
chain 0 gave -ENOENT. Once chain 0 became non-implicit, the same call is
giving -EINVAL. Fix this by returning -ENOENT in that case.

Instead "Cannot find" say "Cannot create".

After erspan_ver is introudced, if erspan_ver is not set in iproute, its
value will be left 0 by default. Since Commit 02f99df1875c ("erspan: fix
invalid erspan version."), it has broken the traffic due to the version
check in erspan_xmit if users are not aware of 'erspan_ver' param, like
using an old version of iproute.
To fix this compatibility problem, it sets erspan_ver to 1 by default
when adding an erspan dev in erspan_setup. Note that we can't do it in
ipgre_netlink_parms, as this function is also used by ipgre_changelink.

After changing rhashtable_walk_start to return void, start_fail would
never be set other value than 0, and the checking for start_fail is
pointless, so remove it.

As Marcelo noticed, in sctp_transport_get_next, it is iterating over
transports but then also accessing the association directly, without
checking any refcnts before that, which can cause an use-after-free
Read.
So fix it by holding transport before accessing the association. With
that, sctp_transport_hold calls can be removed in the later places.
Fixes: 626d16f50f39 ("sctp: export some apis or variables for sctp_diag and reuse some for proc")

The DMA is broken on this specific device for some unknown
reason (probably badly designed or plain broken interface
electronics) and will only work with PIO. Other users of
the same hardware does not have this problem.
Add a specific quirk so that this Gemini device gets
DMA turned off. Also fix up some code around passing the
port information around in probe while we're at it.

when ac/dc switch, driver will be notified by acpi event.
then the power source will be updated. so don't need to
get power source when set power state.

[Why]
There is currently an intermittent hang from a memory leak in
DTN stress testing. It is caused by unfreed memory during driver
disable.
[How]
Do a dc_sink_release in the case that skips it incorrectly.

For SI/Kv, the power state is managed by function
amdgpu_pm_compute_clocks.
when dpm enabled, we should call amdgpu_pm_compute_clocks
to update current power state instand of set boot state.
this change can fix the oops when kfd driver was enabled on Kv.
