The era of hand-rolled HIWORD_UPDATE macros is over, at least for those
drivers that use constant masks.
Like many other Rockchip drivers, rockchip-dfi brings with it its own
HIWORD_UPDATE macro. This variant doesn't shift the value (and like the
others, doesn't do any checking).
Remove it, and replace instances of it with hw_bitfield.h's
FIELD_PREP_WM16. Since FIELD_PREP_WM16 requires contiguous masks and
shifts the value for us, some reshuffling of definitions needs to
happen.
This gives us better compile-time error checking, and in my opinion,
nicer code.
Tested on an RK3568 ODROID-M1 board (LPDDR4X at 1560 MHz, an RK3588
Radxa ROCK 5B board (LPDDR4X at 2112 MHz) and an RK3588 Radxa ROCK 5T
board (LPDDR5 at 2400 MHz). perf measurements were consistent with the
measurements of stress-ng --stream in all cases.

The current shenanigans for duration calculation introduce too much
complexity for a trivial problem, and further the code is hard to patch and
maintain.
Address these issues with a flat look-up table, which is easy to understand
and patch. If leaf driver specific patching is required in future, it is
easy enough to make a copy of this table during driver initialization and
add the chip parameter back.
'chip->duration' is retained for TPM 1.x.
As the first entry for this new behavior address TCG spec update mentioned
in this issue:
https://github.com/raspberrypi/linux/issues/7054
Therefore, for TPM_SelfTest the duration is set to 3000 ms.
This does not categorize a as bug, given that this is introduced to the
spec after the feature was originally made.

In tpm_buf_check_hmac_response(), compare the HMAC values in constant
time using crypto_memneq() instead of in variable time using memcmp().
This is worthwhile to follow best practices and to be consistent with
MAC comparisons elsewhere in the kernel. However, in this driver the
side channel seems to have been benign: the HMAC input data is
guaranteed to always be unique, which makes the usual MAC forgery via
timing side channel not possible. Specifically, the HMAC input data in
tpm_buf_check_hmac_response() includes the "our_nonce" field, which was
generated by the kernel earlier, remains under the control of the
kernel, and is unique for each call to tpm_buf_check_hmac_response().

After reading all the feedback, right now disabling the TPM2_TCG_HMAC
is the right call.
Other views discussed:
A. Having a kernel command-line parameter or refining the feature
otherwise. This goes to the area of improvements. E.g., one
example is my own idea where the null key specific code would be
replaced with a persistent handle parameter (which can be
*unambigously* defined as part of attestation process when
done correctly).
B. Removing the code. I don't buy this because that is same as saying
that HMAC encryption cannot work at all (if really nitpicking) in
any form. Also I disagree on the view that the feature could not
be refined to something more reasoable.
Also, both A and B are worst options in terms of backporting.
Thuss, this is the best possible choice.

A regression was reported to me recently whereby /dev/fb0 had disappeared
from a PowerBook G3 Series "Wallstreet". The problem shows up when the
"video=ofonly" parameter is passed to the kernel, which is what the
bootloader does when "no video driver" is selected. The cause of the
problem is the "offb" string comparison, which got mangled when it got
refactored. Fix it.

When setting a normal alarm, user-space is responsible for using
RTC_AIE_ON/RTC_AIE_OFF to control if alarm irq should be enabled.
But when RTC_UIE_ON is used, interrupts must be enabled so that the
requested irq events are generated.
When RTC_UIE_OFF is used, alarm irq is disabled if there are no other
alarms queued, so this commit brings symmetry to that.

As described in the old comment dating back to
commit 6610e0893b8b ("RTC: Rework RTC code to use timerqueue for events")
from 2010, we have been living with a race window when setting alarm
with an expiry in the near future (i.e. next second).
With 1 second resolution, it can happen that the second ticks after the
check for the timer having expired, but before the alarm is actually set.
When this happen, no alarm IRQ is generated, at least not with some RTC
chips (isl12022 is an example of this).
With UIE RTC timer being implemented on top of alarm irq, being re-armed
every second, UIE will occasionally fail to work, as an alarm irq lost
due to this race will stop the re-arming loop.
For now, I have limited the additional expiry check to only be done for
alarms set to next seconds. I expect it should be good enough, although I
don't know if we can now for sure that systems with loads could end up
causing the same problems for alarms set 2 seconds or even longer in the
future.
I haven't been able to reproduce the problem with this check in place.

Rx processing under normal circumstances has 3 rings - 2 buffer
rings (heads, payloads) and a completion ring. All the rings
have a struct fbnic_ring. Make sure we expose alloc_failed
counter from the buffer rings, previously only the alloc_failed
from the completion ring was reported, even tho all ring types
may increment this counter (buffer rings in __fbnic_fill_bdq()).
This makes the pp_alloc_fail.py test pass, it expects the qstat
to be incrementing as page pool injections happen.

When rings are freed - stats get added to the device level stat
structs. Save the stats from the XDP_TX ring just as Tx stats.
Previously they would be saved to Rx and Tx stats. So we'd not
see XDP_TX packets as Rx during runtime but after an down/up cycle
the packets would appear in stats.
Correct the helper used by ethtool code which does a runtime
config switch.

Make XDP-handled packets appear in the Rx stats. The driver has been
counting XDP_TX packets on the Tx ring, but there wasn't much accounting
on the Rx side (the Rx bytes appear to be incremented on XDP_TX but
XDP_DROP / XDP_ABORT are only counted as Rx drops).
Counting XDP_TX packets (not just bytes) in Rx stats looks like
a simple bug of omission.
The XDP_DROP handling appears to be intentional. Whether XDP_DROP
packets should be counted in interface-level Rx stats is a bit
unclear historically. When we were defining qstats, however,
we clarified based on operational experience that in this context:
name: rx-packets
doc: |
Number of wire packets successfully received and passed to the stack.
For drivers supporting XDP, XDP is considered the first layer
of the stack, so packets consumed by XDP are still counted here.
fbnic does not obey this requirement. Since XDP support has been added
in current release cycle, instead of splitting interface and qstat
handling - make them both follow the qstat definition.
Another small tweak here is that we count bytes as received on the wire
rather than post-XDP bytes (xdp_get_buff_len() vs skb->len).

XDP_TX typically uses no offloads. To optimize XDP we added a "default
descriptor" feature to the chip, which allows us to send XDP frames with
just the buffer descriptors (DMA address + length). All the metadata
descriptors are derived from the queue config.
Commit under Fixes missed adding setting the defaults up when transplanting
the code from the prototype driver. Importantly after reset the "request
completion" bit is not set. Packets still get sent but there's no
completion, so ring is not cleaned up. We can send one ring's worth
of packets and then will start dropping all frames that got the XDP_TX
action from the XDP prog.

Pull pci fix from Bjorn Helgaas:
- Fix a resource lookup regression that broke enumeration of hotplugged
Thunderbolt devices on several platforms (Yangyu Chen)
* tag 'pci-v6.18-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci:
PCI: Fix regression in pci_bus_distribute_available_resources()
|
|
The refactoring in 4292a1e45fd4 ("PCI: Refactor distributing available
memory to use loops") switched pci_bus_distribute_available_resources() to
operate on an array of bridge windows. That accidentally looked up bus
resources via pci_bus_resource_n() and then passed those pointers to helper
routines that expect the resource to belong to the device. As soon as we
execute that code, pci_resource_num() warned because the resource wasn't in
the bridge's resource array.
This happens on my AMD Strix Halo machine with Thunderbolt device; the
error message is shown below:
WARNING: CPU: 6 PID: 272 at drivers/pci/pci.h:471 pci_bus_distribute_available_resources+0x6ad/0x6d0

pciehp_handle_presence_or_link_change+0x1b5/0x350
pciehp_ist+0x147/0x1c0
Fix the regression by always fetching the resource directly from the bridge
with pci_resource_n(bridge, PCI_BRIDGE_RESOURCES + i). This restores the
original behaviour while keeping the refactored structure. Then we can
successfully assign resources to the Thunderbolt device.
