When in fatal error condition, mark device as detached first
and then complete all pending HWRM commands as firmware is not
going to process them and eventually time out. Move the device
to error only if suspend is called when device is in Fatal state.
Also, remove some outdated comments. Remove the stop_irq call
which is no longer required.

A DREQ is sent in 2 situations:
1. When requested by the user.
This DREQ has to wait for a DREP, which will be routed to the user.
2. When the cm_id is destroyed.
This DREQ is generated by the CM to notify the peer that the
connection has been destroyed.
In the latter case, any DREP that is received will be discarded.
There's no need to hold a reference on the cm_id. Today, both
situations are covered by the same function: cm_send_dreq_locked().
When invoked in the cm_id destroy path, the cm_id reference would be
held until the DREQ completes, blocking the destruction. Because it
could take several seconds to minutes before the DREQ receives a DREP,
the destroy call posts a send for the DREQ then immediately cancels the
MAD. However, cancellation is not immediate in the MAD layer. There
could still be a delay before the MAD layer returns the DREQ to the CM.
Moreover, the only guarantee is that the DREQ will be sent at most once.
Introduce a separate flow for sending a DREQ when destroying the cm_id.
The new flow will not hold a reference on the cm_id, allowing it to be
cleaned up immediately. The cancellation trick is no longer needed.
The MAD layer will send the DREQ exactly once.

Typically, when the CM sends a MAD it bumps a reference count
on the associated cm_id. There are some exceptions, such
as when the MAD is a direct response to a receive MAD. For
example, the CM may generate an MRA in response to a duplicate
REQ. But, in general, if a MAD may be sent as a result of
the user invoking an API call (e.g. ib_send_cm_rep(),
ib_send_cm_rtu(), etc.), a reference is taken on the cm_id.
This reference is necessary if the MAD requires a response.
The reference allows routing a response MAD back to the
cm_id, or, if no response is received, allows updating the
cm_id state to reflect the failure.
For MADs which do not generate a response from the
target, however, there's no need to hold a reference on the cm_id.
Such MADs will not be retried by the MAD layer and their
completions do not change the state of the cm_id.
There are 2 internal calls used to allocate MADs which take
a reference on the cm_id: cm_alloc_msg() and cm_alloc_priv_msg().
The latter calls the former. It turns out that all other places
where cm_alloc_msg() is called are for MADs that do not generate
a response from the target: sending an RTU, DREP, REJ, MRA, or
SIDR REP. In all of these cases, there's no need to hold a
reference on the cm_id.
The benefit of dropping unneeded references is that it allows
destruction of the cm_id to proceed immediately. Currently,
the cm_destroy_id() call blocks as long as there's a reference
held on the cm_id. Worse, is that cm_destroy_id() will send
MADs, which it then needs to complete. Sending the MADs is
beneficial, as they notify the peer that a connection is
being destroyed. However, since the MADs hold a reference
on the cm_id, they block destruction and cannot be retried.
Move cm_id referencing from cm_alloc_msg() to cm_alloc_priv_msg().
The latter should hold a reference on the cm_id in all cases but
one, which will be handled in a separate patch. cm_alloc_priv_msg()
is used when sending a REQ, REP, DREQ, and SIDR REQ, all of which
require a response.
Also, merge common code into cm_alloc_priv_msg() and combine the
freeing of all messages which do not need a response.

In several situations the CM may send a reply to a received MAD
without the reply being directly linked with a cm_id. For
example, it may send a REJ in response to a REQ which does not
match a listener. Or, it may send a DREP in response to a DREQ
if the cm_id has already been destroyed. This can happen if the
original DREP was lost and the DREQ was retried.
When such a response MAD completes, it updates a counter tracking
how many MADs were retried. However, not all response MADs issued
directly by the CM may be retries. The REJ mentioned in the example
above is such a case. To distinguish between responses which were
retries versus those that are not, the send_handler performs the
following check: is a retry if the response is not associated with
a cm_id and the response is not a REJ message.
Replace this indirect method of checking if a response is a retry
with an explicit check. Note that these retries are generated
directly by the CM, rather than retried by the MAD layer.
This change will be needed by later changes which would otherwise
break the indirect check.

When we load SSDT from efi variable (specified with efivar_ssdt=<var>
boot command line argument) a name for the variable is allocated
dynamically because we traverse all EFI variables. Unlike ACPI table
data, which is later used by ACPI engine, the name is no longer needed
once traverse is complete -- don't forget to free this memory.
Same time we silently ignore any errors happened here let's print a
message if something went wrong (but do not exit since this is not a
critical error and the system should continue to boot).
Also while here -- add a note why we keep SSDT table on success.

When CONFIG_CMDLINE_OVERRIDE or CONFIG_CMDLINE_FORCE are configured, the
command line provided by the boot stack should be ignored, and only the
built-in command line should be taken into account.
Add the required handling of this when dealing with initrd= or dtb=
command line options in the EFI stub.
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
|

CONFIG_CMDLINE, when set, is supposed to serve either as a fallback when
no command line is provided by the bootloader, or to be taken into account
unconditionally, depending on the configured options.
The initrd and dtb loader ignores CONFIG_CMDLINE in either case, and
only takes the EFI firmware provided load options into account. This
means that configuring the kernel with initrd= or dtb= on the built-in
command line does not produce the expected result.
Fix this by doing a separate pass over the built-in command line when
dealing with initrd= or dtb= options.

Because the af-xdp will introduce a new xmit type, so I refactor the
xmit type mechanism first.
We know both xdp_frame and sk_buff are at least 4 bytes aligned.
For the xdp tx, we do not pass any pointer to virtio core as data,
we just need to pass the len of the packet. So we will push len
to the void pointer. We can make sure the pointer is 4 bytes aligned.
And the data structure of AF_XDP also is at least 4 bytes aligned.
So the last two bits of the pointers are free, we can't use these to
distinguish them.

01 for SKB_ORPHAN

The current configuration sets the virtqueue (vq) to premapped mode,
implying that all buffers submitted to this queue must be mapped ahead
of time. This presents a challenge for the virtnet send queue (sq): the
virtnet driver would be required to keep track of dma information for vq
size * 17, which can be substantial. However, if the premapped mode were
applied on a per-buffer basis, the complexity would be greatly reduced.
With AF_XDP enabled, AF_XDP buffers would become premapped, while kernel
skb buffers could remain unmapped.
And consider that some sgs are not generated by the virtio driver,
that may be passed from the block stack. So we can not change the
sgs, new APIs are the better way.
So we pass the new argument 'premapped' to indicate the buffers
submitted to virtio are premapped in advance. Additionally,
DMA unmap operations for these buffers will be bypassed.

Currently when FDB entries are added to or deleted from a VXLAN netdevice,
the VXLAN driver emits one notification, including the VXLAN-specific
attributes. The core however always sends a notification as well, a generic
one. Thus two notifications are unnecessarily sent for these operations. A
similar situation comes up with bridge driver, which also emits
notifications on its own:
# ip link add name vx type vxlan id 1000 dstport 4789
# bridge monitor fdb &
[1] 1981693
# bridge fdb add de:ad:be:ef:13:37 dev vx self dst 192.0.2.1
de:ad:be:ef:13:37 dev vx dst 192.0.2.1 self permanent
de:ad:be:ef:13:37 dev vx self permanent
In order to prevent this duplicity, add a paremeter to ndo_fdb_add,
bool *notified. The flag is primed to false, and if the callee sends a
notification on its own, it sets it to true, thus informing the core that
it should not generate another notification.

Instead of failing to use MSI-X if resources aren't configured exactly
right, use the resources we do have. Since we could start using large
numbers of rq resources, we do limit the rq count to what
netif_get_num_default_rss_queues() recommends.

Save the resources counts for wq,rq,cq, and interrupts in *_avail variables
so that we don't lose the information when adjusting the counts we are
actually using.

The VIC hardware has a constraint that the MSIX interrupt used for errors
be specified as a 7 bit number. Before this patch, it was allocated after
the I/O interrupts, which would cause a problem if 128 or more I/O
interrupts are in use.
So make the required interrupts come before the I/O interrupts to
guarantee the error interrupt offset never exceeds 7 bits.

When configuring flow steering rules, the driver is currently going
through a reset for all errors from the device. Instead, the driver
should only reset when there's a timeout error from the device.

phylib has two eee_enabled members. Some parts of the code are using
phydev->eee_enabled, other parts are using phydev->eee_cfg.eee_enabled.
This leads to incorrect behaviour as their state goes out of sync.
ethtool --show-eee shows incorrect information, and --set-eee sometimes
doesn't take effect.
Fix this by only having one eee_enabled member - that in eee_cfg.

Current implementation of gettimex64() makes at least 3 PCIe reads to
get current PHC time. It takes at least 2.2us to get this value back to
userspace. At the same time there is cached value of upper bits of PHC
available for packet timestamps already. This patch reuses cached value
to speed up reading of PHC time.

Pull-in kunit kconfig fix
|
|
Some configurations want to enable CONFIG_KUNIT without enabling
CONFIG_OF_OVERLAY. The kunit overlay code already skips if
CONFIG_OF_OVERLAY isn't enabled, so this select here isn't really doing
anything besides making it easier to run the tests without them
skipping. Remove the select and move the config setting to the
drivers/of/.kunitconfig file so that the overlay tests can be run with
or without CONFIG_OF_OVERLAY set to test either behavior.
Fixes: 5c9dd72d8385 ("of: Add a KUnit test for overlays and test managed APIs")
