Second shared stable tag between EFI and LoongArch trees
This is necessary because the EFI libstub refactoring patches are mostly
directed at enabling LoongArch to wire up generic EFI boot support
without being forced to consume DT properties that conflict with
information that EFI also provides, e.g., memory map and reservations,
etc.
|
|
LoongArch does not use FDT or DT natively [yet], and the only reason it
currently uses it is so that it can reuse the existing EFI stub code.
Overloading the DT with data passed between the EFI stub and the core
kernel has been a source of problems: there is the overlap between
information provided by EFI which DT can also provide (initrd base/size,
command line, memory descriptions), requiring us to reason about which
is which and what to prioritize. It has also resulted in ABI leaks,
i.e., internal ABI being promoted to external ABI inadvertently because
the bootloader can set the EFI stub's DT properties as well (e.g.,
"kaslr-seed"). This has become especially problematic with boot
environments that want to pretend that EFI boot is being done (to access
ACPI and SMBIOS tables, for instance) but have no ability to execute the
EFI stub, and so the environment that the EFI stub creates is emulated
[poorly, in some cases].
Another downside of treating DT like this is that the DT binary that the
kernel receives is different from the one created by the firmware, which
is undesirable in the context of secure and measured boot.
Given that LoongArch support in Linux is brand new, we can avoid these
pitfalls, and treat the DT strictly as a hardware description, and use a
separate handover method between the EFI stub and the kernel. Now that
initrd loading and passing the EFI memory map have been refactored into
pure EFI routines that use EFI configuration tables, the only thing we
need to pass directly is the kernel command line (even if we could pass
this via a config table as well, it is used extremely early, so passing
it directly is preferred in this case.)

Expose the EFI boot time memory map to the kernel via a configuration
table. This is arch agnostic and enables future changes that remove the
dependency on DT on architectures that don't otherwise rely on it.

Refactor the generic EFI stub entry code so that all the dependencies on
device tree are abstracted and hidden behind a generic efi_boot_kernel()
routine that can also be implemented in other ways. This allows users of
the generic stub to avoid using FDT for passing information to the core
kernel.

Use a EFI configuration table to pass the initrd to the core kernel,
instead of per-arch methods. This cleans up the code considerably, and
should make it easier for architectures to get rid of their reliance on
DT for doing EFI boot in the future.

The block device uses multiple queues to access emmc. There will be up to 3
requests in the hsq of the host. The current code will check whether there
is a request doing recovery before entering the queue, but it will not check
whether there is a request when the lock is issued. The request is in recovery
mode. If there is a request in recovery, then a read and write request is
initiated at this time, and the conflict between the request and the recovery
request will cause the data to be trampled.

Now that the scratch page and page directories have a reference back to
the i915_address_space, we cannot do an immediate free of the ppgtt upon
error as those buffer objects will perform a later i915_vm_put in their
deferred frees.
The downside is that by replacing the onion unwind along the error
paths, the ppgtt cleanup must handle a partially constructed vm. This
includes ensuring that the vm->cleanup is set prior to the error path.

We always allocate two DPLLs (TC and TBT) for TC ports. This
is because we can't know ahead of time wherher we need to put
the PHY into DP-Alt or TBT mode.
However during readout we can obviously only read out the state
of the DPLL that the port is actually using. Thus the state after
readout will not have both DPLLs populated.
We run into problems if during readout the TC port is in DP-Alt
mode, but we then perform a modeset on the port without going
through the full .compute_config() machinery, and during said
modeset the port cannot be switched back into DP-Alt mode and
we need to take the TBT fallback path. Such a modeset can
happen eg. due to cdclk reprogramming.
This wasn't a problem earlier because we did all the DPLL
calculations much later in the modeset. So even if flagged
a modeset very late we'd still have gone through the DPLL
calculations. But now all the DPLL calculations happen much
earlier and so we need to deal with it, or else we'll attempt
a modeset without a DPLL.
To guarantee that we always have both DPLLs fully cal/ulated
for TC ports force a full modeset computation during the
initial commit.

Commit 00c6cbfd4e8a ("drm/i915: move pipe_mask and cpu_transcoder_mask
to runtime info") moved the pipe_mask member from struct
intel_device_info to intel_runtime_info, but overlooked some of our
platforms initializing device info .display = {}. This is significant,
as pipe_mask is the single point of truth for a device having a display
or not; the platforms in question left pipe_mask to whatever was set for
the platforms they "inherit" from in the complex macro scheme we have.
Add new NO_DISPLAY macro initializing .__runtime.pipe_mask = 0, which
will cause the device info .display sub-struct to be zeroed in
intel_device_info_runtime_init(). A better solution (or simply audit of
proper use of HAS_DISPLAY() checks) is required before moving forward
with [1].
Also clear all the display related members in runtime info if there's no
display. The latter is a bit tedious, but it's for completeness at this
time, to ensure similar functionality as before.

====================
net: openvswitch: metering and conntrack in userns
Currently using openvswitch in a non-initial user namespace, e.g., an
unprivileged container, is possible but without metering and conntrack
support. This is due to the restriction of the corresponding Netlink
interfaces to the global CAP_NET_ADMIN.
This simple patches switch from GENL_ADMIN_PERM to GENL_UNS_ADMIN_PERM
in several cases to allow this also for the unprivileged container
use case.
We tested this for unprivileged containers created by the container
manager of GyroidOS (gyroidos.github.io). However, for other container
managers such as LXC or systemd which provide unprivileged containers
this should be apply equally.

This commit fixes DMA engine reset timeout issue in suspend/resume
with ADLink I-Pi SMARC Plus board which dmesg shows:

[ 55.784115] intel-eth-pci 0000:00:1d.2 enp0s29f2: stmmac_open: Hw setup failed
...
The issue is related with serdes which impacts clock. There is
serdes in ADLink I-Pi SMARC board ethernet controller. Please refer to
commit b9663b7ca6ff78 ("net: stmmac: Enable SERDES power up/down sequence")
for detial. When issue is reproduced, DMA engine clock is not ready
because serdes is not powered up.
To reproduce DMA engine reset timeout issue with hardware which has
serdes in GBE controller, install Ubuntu. In Ubuntu GUI, click
"Power Off/Log Out" -> "Suspend" menu, it disables network interface,
then goes to sleep mode. When it wakes up, it enables network
interface again. Stmmac driver is called in this way:
1. stmmac_release: Stop network interface. In this function, it
disables DMA engine and network interface;
2. stmmac_suspend: It is called in kernel suspend flow. But because
network interface has been disabled(netif_running(ndev) is
false), it does nothing and returns directly;
3. System goes into S3 or S0ix state. Some time later, system is
waken up by keyboard or mouse;
4. stmmac_resume: It does nothing because network interface has
been disabled;
5. stmmac_open: It is called to enable network interace again. DMA
engine is initialized in this API, but serdes is not power on so
there will be DMA engine reset timeout issue.
Similarly, serdes powerdown should be added in stmmac_release.
Network interface might be disabled by cmd "ifconfig eth0 down",
DMA engine, phy and mac have been disabled in ndo_stop callback,
serdes should be powered down as well. It doesn't make sense that
serdes is on while other components have been turned off.
If ethernet interface is in enabled state(netif_running(ndev) is true)
before suspend/resume, the issue couldn't be reproduced because serdes
could be powered up in stmmac_resume.
Because serdes_powerup is added in stmmac_open, it doesn't need to be
called in probe function.

In idmouse_create_image, if any ftip_command fails, it will
go to the reset label. However, this leads to the data in
bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check
for valid image incurs an uninitialized dereference.
Fix this by moving the check before reset label since this
check only be valid if the data after bulk_in_buffer[HEADER]
has concrete data.
Note that this is found by KMSAN, so only kernel compilation
is tested.

In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER and prints the
error name. It also sets the defer probe reason which can be
checked later through debugfs. It's more simple in error path.

From the document, platform_get_irq_byname_optional only returns

Fix this by removing the zero value checking.

Commit 6911458dc428 ("wifi: mac80211: mlme: refactor assoc success
handling") moved the per-link setup out of ieee80211_assoc_success() into a
new function ieee80211_assoc_config_link() but missed to remove the unlock
of 'sta_mtx' in case of HE capability/operation missing on HE AP, which
leads to a double unlock:
ieee80211_assoc_success() {
...
ieee80211_assoc_config_link() {
...
if (!(link->u.mgd.conn_flags & IEEE80211_CONN_DISABLE_HE) &&
(!elems->he_cap || !elems->he_operation)) {
mutex_unlock(&sdata->local->sta_mtx);
...
}
...
}
...
mutex_unlock(&sdata->local->sta_mtx);
...
}

Commit 98b0b467466c ("wifi: mac80211: mlme: use correct link_sta")
switched to link station instead of deflink and added some checks to do
that, which are done with the 'sta_mtx' mutex held. However, the error
path of these checks does not unlock 'sta_mtx' before returning.
