Fix the MPIC.PSMCS value following the programming example in the
section 6.4.2 Management Data Clock (MDC) Setting, Ethernet MAC IP,
S4 Hardware User Manual Rev.1.00.
The value is calculated by
MPIC.PSMCS = clk[MHz] / (MDC frequency[MHz] * 2) - 1
with the input clock frequency from clk_get_rate() and MDC frequency
of 2.5MHz. Otherwise, this driver cannot communicate PHYs on the R-Car
S4 Starter Kit board.

A recent ext4 patch posting from Jan Kara reminded me of a
discussion a year ago about fstrim in progress preventing kernels
from suspending. The fix is simple, we should do the same for XFS.
This removes the -ERESTARTSYS error return from this code, replacing
it with either the last error seen or the number of blocks
successfully trimmed up to the point where we detected the stop
condition.

fstrim will hold the AGF lock for as long as it takes to walk and
discard all the free space in the AG that meets the userspace trim
criteria. For AGs with lots of free space extents (e.g. millions)
or the underlying device is really slow at processing discard
requests (e.g. Ceph RBD), this means the AGF hold time is often
measured in minutes to hours, not a few milliseconds as we normal
see with non-discard based operations.
This can result in the entire filesystem hanging whilst the
long-running fstrim is in progress. We can have transactions get
stuck waiting for the AGF lock (data or metadata extent allocation
and freeing), and then more transactions get stuck waiting on the
locks those transactions hold. We can get to the point where fstrim
blocks an extent allocation or free operation long enough that it
ends up pinning the tail of the log and the log then runs out of
space. At this point, every modification in the filesystem gets
blocked. This includes read operations, if atime updates need to be
made.
To fix this problem, we need to be able to discard free space
extents safely without holding the AGF lock. Fortunately, we already
do this with online discard via busy extents. We can mark free space
extents as "busy being discarded" under the AGF lock and then unlock
the AGF, knowing that nobody will be able to allocate that free
space extent until we remove it from the busy tree.
Modify xfs_trim_extents to use the same asynchronous discard
mechanism backed by busy extents as is used with online discard.
This results in the AGF only needing to be held for short periods of
time and it is never held while we issue discards. Hence if discard
submission gets throttled because it is slow and/or there are lots
of them, we aren't preventing other operations from being performed
on AGF while we wait for discards to complete...

Report the maximum number of IBs that can be pushed with a single
DRM_IOCTL_NOUVEAU_EXEC through DRM_IOCTL_NOUVEAU_GETPARAM.
While the maximum number of IBs per ring might vary between chipsets,
the kernel will make sure that userspace can only push a fraction of the
maximum number of IBs per ring per job, such that we avoid a situation
where there's only a single job occupying the ring, which could
potentially lead to the ring run dry.
Using DRM_IOCTL_NOUVEAU_GETPARAM to report the maximum number of IBs
that can be pushed with a single DRM_IOCTL_NOUVEAU_EXEC implies that
all channels of a given device have the same ring size.

application passes in memory that resides in highmem for the rings,
then we should fail that ring creation. We fail it with -EINVAL, which

When raid5_get_active_stripe is called with a ctx containing a stripe_head in
its batch_last pointer, it can cause a deadlock if the task sleeps waiting on
another stripe_head to become available. The stripe_head held by batch_last
can be blocking the advancement of other stripe_heads, leading to no
stripe_heads being released so raid5_get_active_stripe waits forever.
Like with the quiesce state handling earlier in the function, batch_last
needs to be released by raid5_get_active_stripe before it waits for another
stripe_head.

The ETHTOOL_A_PLCA_ENABLED data type is u8. But while parsing the
value from the attribute, nla_get_u32() is used in the plca_update_sint()
function instead of nla_get_u8(). So plca_cfg.enabled variable is updated
with some garbage value instead of 0 or 1 and always enables plca even
though plca is disabled through ethtool application. This bug has been
fixed by parsing the values based on the attributes type in the policy.

io_lockdep_assert_cq_locked() checks that locking is correctly done when
a CQE is posted. If the ring is setup in a disabled state with
IORING_SETUP_R_DISABLED, then ctx->submitter_task isn't assigned until
the ring is later enabled. We generally don't post CQEs in this state,
as no SQEs can be submitted. However it is possible to generate a CQE
if tagged resources are being updated. If this happens and PROVE_LOCKING
is enabled, then the locking check helper will dereference
ctx->submitter_task, which hasn't been set yet.
Fixup io_lockdep_assert_cq_locked() to handle this case correctly. While
at it, convert it to a static inline as well, so that generated line
offsets will actually reflect which condition failed, rather than just
the line offset for io_lockdep_assert_cq_locked() itself.

syzbot reports that registering a mapped buffer ring on arm32 can
trigger an OOPS. Registered buffer rings have two modes, one of them
is the application passing in the memory that the buffer ring should
reside in. Once those pages are mapped, we use page_address() to get
a virtual address. This will obviously fail on highmem pages, which
aren't mapped.
Add a check if we have any highmem pages after mapping, and fail the
attempt to register a provided buffer ring if we do. This will return
the same error as kernels that don't support provided buffer rings to
begin with.

The expectation is that placing a task at avg_vruntime() makes it
eligible. Turns out there is a corner case where this is not the case.
Specifically, avg_vruntime() relies on the fact that integer division
is a flooring function (eg. it discards the remainder). By this
property the value returned is slightly left of the true average.
However! when the average is a negative (relative to min_vruntime) the
effect is flipped and it becomes a ceil, with the result that the
returned value is just right of the average and thus not eligible.

The flexible structure (a structure that contains a flexible-array member
at the end) `qed_ll2_tx_packet` is nested within the second layer of
`struct qed_ll2_info`:
struct qed_ll2_tx_packet {
...
/* Flexible Array of bds_set determined by max_bds_per_packet */
struct {
struct core_tx_bd *txq_bd;
dma_addr_t tx_frag;
u16 frag_len;
} bds_set[];
};
struct qed_ll2_tx_queue {
...
struct qed_ll2_tx_packet cur_completing_packet;
};
struct qed_ll2_info {
...
struct qed_ll2_tx_queue tx_queue;
struct qed_ll2_cbs cbs;
};
The problem is that member `cbs` in `struct qed_ll2_info` is placed just
after an object of type `struct qed_ll2_tx_queue`, which is in itself
an implicit flexible structure, which by definition ends in a flexible
array member, in this case `bds_set`. This causes an undefined behavior
bug at run-time when dynamic memory is allocated for `bds_set`, which
could lead to a serious issue if `cbs` in `struct qed_ll2_info` is
overwritten by the contents of `bds_set`. Notice that the type of `cbs`
is a structure full of function pointers (and a cookie :) ):
include/linux/qed/qed_ll2_if.h:
107 typedef
108 void (*qed_ll2_complete_rx_packet_cb)(void *cxt,
109 struct qed_ll2_comp_rx_data *data);
110
111 typedef
112 void (*qed_ll2_release_rx_packet_cb)(void *cxt,
113 u8 connection_handle,
114 void *cookie,
115 dma_addr_t rx_buf_addr,
116 bool b_last_packet);
117
118 typedef
119 void (*qed_ll2_complete_tx_packet_cb)(void *cxt,
120 u8 connection_handle,
121 void *cookie,
122 dma_addr_t first_frag_addr,
123 bool b_last_fragment,
124 bool b_last_packet);
125
126 typedef
127 void (*qed_ll2_release_tx_packet_cb)(void *cxt,
128 u8 connection_handle,
129 void *cookie,
130 dma_addr_t first_frag_addr,
131 bool b_last_fragment, bool b_last_packet);
132
133 typedef
134 void (*qed_ll2_slowpath_cb)(void *cxt, u8 connection_handle,
135 u32 opaque_data_0, u32 opaque_data_1);
136
137 struct qed_ll2_cbs {
138 qed_ll2_complete_rx_packet_cb rx_comp_cb;
139 qed_ll2_release_rx_packet_cb rx_release_cb;
140 qed_ll2_complete_tx_packet_cb tx_comp_cb;
141 qed_ll2_release_tx_packet_cb tx_release_cb;
142 qed_ll2_slowpath_cb slowpath_cb;
143 void *cookie;
144 };
Fix this by moving the declaration of `cbs` to the middle of its
containing structure `qed_ll2_info`, preventing it from being
overwritten by the contents of `bds_set` at run-time.
This bug was introduced in 2017, when `bds_set` was converted to a
one-element array, and started to be used as a Variable Length Object
(VLO) at run-time.

Commit b0e214d21203 ("netfilter: keep conntrack reference until
IPsecv6 policy checks are done") is a direct copy of the old
commit b59c270104f0 ("[NETFILTER]: Keep conntrack reference until
IPsec policy checks are done") but for IPv6. However, it also
copies a bug that this old commit had. That is: when the third
packet of 3WHS connection establishment contains payload, it is
added into socket receive queue without the XFRM check and the
drop of connection tracking context.
That leads to nf_conntrack module being impossible to unload as
it waits for all the conntrack references to be dropped while
the packet release is deferred in per-cpu cache indefinitely, if
not consumed by the application.
The issue for IPv4 was fixed in commit 6f0012e35160 ("tcp: add a
missing nf_reset_ct() in 3WHS handling") by adding a missing XFRM
check and correctly dropping the conntrack context. However, the
issue was introduced to IPv6 code afterwards. Fixing it the
same way for IPv6 now.

After deleting an interface address in fib_del_ifaddr(), the function
scans the fib_info list for stray entries and calls fib_flush() and
fib_table_flush(). Then the stray entries will be deleted silently and no
RTM_DELROUTE notification will be sent.
This lack of notification can make routing daemons, or monitor like
`ip monitor route` miss the routing changes. e.g.
+ ip link add dummy1 type dummy
+ ip link add dummy2 type dummy
+ ip link set dummy1 up
+ ip link set dummy2 up
+ ip addr add 192.168.5.5/24 dev dummy1
+ ip route add 7.7.7.0/24 dev dummy2 src 192.168.5.5
+ ip -4 route
7.7.7.0/24 dev dummy2 scope link src 192.168.5.5
192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5
+ ip monitor route
+ ip addr del 192.168.5.5/24 dev dummy1
Deleted 192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5
Deleted broadcast 192.168.5.255 dev dummy1 table local proto kernel scope link src 192.168.5.5
Deleted local 192.168.5.5 dev dummy1 table local proto kernel scope host src 192.168.5.5
As Ido reminded, fib_table_flush() isn't only called when an address is
deleted, but also when an interface is deleted or put down. The lack of
notification in these cases is deliberate. And commit 7c6bb7d2faaf
("net/ipv6: Add knob to skip DELROUTE message on device down") introduced
a sysctl to make IPv6 behave like IPv4 in this regard. So we can't send
the route delete notify blindly in fib_table_flush().
To fix this issue, let's add a new flag in "struct fib_info" to track the
deleted prefer source address routes, and only send notify for them.
After update:
+ ip monitor route
+ ip addr del 192.168.5.5/24 dev dummy1
Deleted 192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5

ovl_permission() accesses ->layers[...].mnt; we can't have ->layers
freed without an RCU delay on fs shutdown.
Fortunately, kern_unmount_array() that is used to drop those mounts
does include an RCU delay, so freeing is delayed; unfortunately, the
array passed to kern_unmount_array() is formed by mangling ->layers
contents and that happens without any delays.
The ->layers[...].name string entries are used to store the strings to
display in "lowerdir=..." by ovl_show_options(). Those entries are not
accessed in RCU walk.
Move the name strings into a separate array ofs->config.lowerdirs and
reuse the ofs->config.lowerdirs array as the temporary mount array to
pass to kern_unmount_array().

SNP retrieves the majority of CPUID information from the SNP CPUID page.
But there are times when that information needs to be supplemented by the
hypervisor, for example, obtaining the initial APIC ID of the vCPU from
leaf 1.
The current implementation uses the MSR protocol to retrieve the data from
the hypervisor, even when a GHCB exists. The problem arises when an NMI
arrives on return from the VMGEXIT. The NMI will be immediately serviced
and may generate a #VC requiring communication with the hypervisor.
Since a GHCB exists in this case, it will be used. As part of using the
GHCB, the #VC handler will write the GHCB physical address into the GHCB
MSR and the #VC will be handled.
When the NMI completes, processing resumes at the site of the VMGEXIT
which is expecting to read the GHCB MSR and find a CPUID MSR protocol
response. Since the NMI handling overwrote the GHCB MSR response, the
guest will see an invalid reply from the hypervisor and self-terminate.
Fix this problem by using the GHCB when it is available. Any NMI
received is properly handled because the GHCB contents are copied into
a backup page and restored on NMI exit, thus preserving the active GHCB
request or result.

The reason is the mentioned commit changed tegra_vi_graph_find_entity() to
search for an entity in the done notifier list:
> @@ -1464,7 +1464,7 @@ tegra_vi_graph_find_entity(struct tegra_vi_channel *chan,

> entity = to_tegra_vi_graph_entity(asd);
> if (entity->asd.match.fwnode == fwnode)
> return entity;
This is not always correct, being tegra_vi_graph_find_entity() called in
three locations, in this order:
1. tegra_vi_graph_parse_one() -- called while probing
2. tegra_vi_graph_notify_bound() -- the .bound notifier op
3. tegra_vi_graph_build() -- called in the .complete notifier op
Locations 1 and 2 are called before moving the entity from waiting_list to
done_list, thus they won't find what they are looking for in
done_list. Location 3 happens afterwards and thus it is not broken, however
it means tegra_vi_graph_find_entity() should not search in the same list
every time.
The error appears at step 1: tegra_vi_graph_parse_one() iterates
recursively until it finds the entity already notified, which now never
happens.
Fix by passing the specific notifier list pointer to
tegra_vi_graph_find_entity() instead of the channel, so each caller can
search in whatever list is correct.
Also improve the tegra_vi_graph_find_entity() comment.

In the pathological case of building sky2 with 16k PAGE_SIZE, the
frag_addr[] array would never be used, so the original code was correct
that size should be 0. But the compiler now gets upset with 0 size arrays
in places where it hasn't eliminated the code that might access such an
array (it can't figure out that in this case an rx skb with fragments
would never be created). To keep the compiler happy, make sure there is
at least 1 frag_addr in struct rx_ring_info:

Since commit 23d775f12dcd ("net: dsa: mv88e6xxx: Wait for EEPROM done
before HW reset") the following error is seen on a imx8mn board with
a 88E6320 switch:
mv88e6085 30be0000.ethernet-1:00: Timeout waiting for EEPROM done
This board does not have an EEPROM attached to the switch though.
This problem is well explained by Andrew Lunn:
"If there is an EEPROM, and the EEPROM contains a lot of data, it could
be that when we perform a hardware reset towards the end of probe, it
interrupts an I2C bus transaction, leaving the I2C bus in a bad state,
and future reads of the EEPROM do not work.
The work around for this was to poll the EEInt status and wait for it
to go true before performing the hardware reset.
However, we have discovered that for some boards which do not have an
EEPROM, EEInt never indicates complete. As a result,
mv88e6xxx_g1_wait_eeprom_done() spins for a second and then prints a
warning.
We probably need a different solution than calling
mv88e6xxx_g1_wait_eeprom_done(). The datasheet for 6352 documents the
EEPROM Command register:
bit 15 is:
EEPROM Unit Busy. This bit must be set to a one to start an EEPROM
operation (see EEOp below). Only one EEPROM operation can be
executing at one time so this bit must be zero before setting it to
a one. When the requested EEPROM operation completes this bit will
automatically be cleared to a zero. The transition of this bit from
a one to a zero can be used to generate an interrupt (the EEInt in
Global 1, offset 0x00).
and more interesting is bit 11:
Register Loader Running. This bit is set to one whenever the
register loader is busy executing instructions contained in the
EEPROM."
Change to using mv88e6xxx_g2_eeprom_wait() to fix the timeout error
when the EEPROM chip is not present.
