+Subject: bootconfig: Fix negative seeks on 32-bit with LFS enabled
+Forwarded: https://lore.kernel.org/linux-trace-kernel/aKHlevxeg6Y7UQrz@decadent.org.uk/T/
+
+Commit 26dda5769509 "tools/bootconfig: Cleanup bootconfig footer size
+calculations" replaced some expressions of type int with the
+BOOTCONFIG_FOOTER_SIZE macro, which expands to an expression of type
+size_t, which is unsigned.
+
+On 32-bit architectures with LFS enabled (i.e. off_t is 64-bit), the
+seek offset of -BOOTCONFIG_FOOTER_SIZE now turns into a positive
+value.
+
+Fix this by casting the size to off_t before negating it.

+Subject: bootconfig: Fix unaligned access when building footer
+Forwarded: https://lore.kernel.org/linux-trace-kernel/aIC-NTw-cdm9ZGFw@decadent.org.uk/T/
+
+Currently we add padding between the bootconfig text and footer to
+ensure that the footer is aligned within the initramfs image.
+However, because only the bootconfig data is held in memory, not the
+full initramfs image, the footer may not be naturally aligned in
+memory.
+
+This can result in an alignment fault (SIGBUS) when writing the footer
+on some architectures, such as sparc.
+
+Build the footer in a struct on the stack before adding it to the
+buffer.

-some shells, including dash, will not pass through environment

+Date: Thu, 30 May 2024 13:14:32 +0100
+Forwarded: not-needed
+
+On an installed Debian system, firmware packages will normally be
+installed automatically based on a mapping of device IDs to firmware.
+Within the Debian installer this has not yet happened and we need a
+way to detect missing firmware.
+
+Although many/most drivers log firmware loading failures, they do so
+using many different formats.  This adds a single log message to the
+firmware loader, which the installer's hw-detect package will look
+for.  The log level is set to "info" because some failures are
+expected and we do not want to confuse users with bogus error messages
+(like in bug #966218).
+
+NOTE: The log message format must not be changed without coordinating
+this with the check-missing-firmware.sh in hw-detect.

+Origin: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/commit?id=a5d70c55c603233c192b375f72116a395909da28
+
+UEFI machines can be booted in Secure Boot mode.  Add an EFI_SECURE_BOOT
+flag that can be passed to efi_enabled() to find out whether secure boot is
+enabled.
+
+Move the switch-statement in x86's setup_arch() that inteprets the
+secure_boot boot parameter to generic code and set the bit there.

-
-    That change turned out to be more trouble than it's worth.  Failing the
-    build is an extreme measure which sometimes gets too much attention and
-    blocks CI build testing.
-
-    These fatal-type warnings aren't yet as rare as we'd hope, due to the
-    ever-increasing matrix of supported toolchains/plugins and their
-    fast-changing nature as of late.
-
-    Also, there are more people (and bots) looking for objtool warnings than
-    ever before, so even non-fatal warnings aren't likely to be ignored for
-    long.

+
+Frequent crashes have been observed on MT7916 based platforms. While the
+root of these crashes are currently unknown, they happen when decoding
+rate information of connected STAs in AP mode. The rate-information is
+associated with a band which is not available on the PHY.
+
+Check for this condition in order to avoid crashing the whole system.
+This patch should be removed once the roout cause has been found and
+fixed.

+Subject: [PATCH] mac80211: sta: randomize BA session dialog token allocator
+
+We currently always start the dialog token generator at zero,
+so the first dialog token we use is always 1. This would be
+OK if we had a perfect guarantee that we always do a proper
+deauth/re-auth handshake, but in IBSS mode this doesn't always
+happen properly.
+
+To make problems with block ack (aggregation) sessions getting
+stuck less likely, randomize the dialog token so if we start a
+new session but the peer still has old state for us, it can
+better detect this.
+
+This is really just a workaround to make things a bit more
+robust than they are now - a better fix would be to do a full
+authentication handshake in IBSS mode upon having discovered a
+new station, and on the receiver resetting the state (removing
+and re-adding the station) on receiving the authentication
+packet.

+Subject: [PATCH] mac80211: minstrel_ht: rework rate downgrade code and
+ max_prob rate selection
+
+The current fallback code for fast rate switching on potentially failing rates
+is triggering too often if there is some strong noise on the channel. This can
+lead to wild fluctuations in the rate selection.
+Additionally, switching down to max_prob_rate can create a significant gap down
+in throughput, especially when using only 2 spatial streams, because max_prob_rate
+is limited to using fewer streams than the max_tp rates.
+In order to improve throughput without reducing reliability too much, use the
+rate downgrade code for the max_prob_rate only, and allow the non-downgraded
+max_prob_rate to use as many spatial streams as the max_tp rates

+
+Given the typical AQL budget and queue length, a quantum of 256 with the
+default station weight often requires iterating over all queues frequently,
+until one of them becomes eligible.
+Improve performance by using 8 times station weight as scheduler quantum

+Excessive broadcast traffic with little competing unicast traffic can easily

+Subject: [PATCH] sched: sch_cake: fix bulk flow accounting logic for host
+ fairness
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In sch_cake, we keep track of the count of active bulk flows per host,
+when running in dst/src host fairness mode, which is used as the
+round-robin weight when iterating through flows. The count of active
+bulk flows is updated whenever a flow changes state.
+
+This has a peculiar interaction with the hash collision handling: when a
+hash collision occurs (after the set-associative hashing), the state of
+the hash bucket is simply updated to match the new packet that collided,
+and if host fairness is enabled, that also means assigning new per-host
+state to the flow. For this reason, the bulk flow counters of the
+host(s) assigned to the flow are decremented, before new state is
+assigned (and the counters, which may not belong to the same host
+anymore, are incremented again).
+
+Back when this code was introduced, the host fairness mode was always
+enabled, so the decrement was unconditional. When the configuration
+flags were introduced the *increment* was made conditional, but
+the *decrement* was not. Which of course can lead to a spurious
+decrement (and associated wrap-around to U16_MAX).
+
+AFAICT, when host fairness is disabled, the decrement and wrap-around
+happens as soon as a hash collision occurs (which is not that common in
+itself, due to the set-associative hashing). However, in most cases this
+is harmless, as the value is only used when host fairness mode is
+enabled. So in order to trigger an array overflow, sch_cake has to first
+be configured with host fairness disabled, and while running in this
+mode, a hash collision has to occur to cause the overflow. Then, the
+qdisc has to be reconfigured to enable host fairness, which leads to the
+array out-of-bounds because the wrapped-around value is retained and
+used as an array index. It seems that syzbot managed to trigger this,
+which is quite impressive in its own right.
+
+This patch fixes the issue by introducing the same conditional check on
+decrement as is used on increment.
+
+The original bug predates the upstreaming of cake, but the commit listed
+in the Fixes tag touched that code, meaning that this patch won't apply
+before that.
+
+Fixes: 712639929912 ("sch_cake: Make the dual modes fairer")

-Subject: cpufreq/amd-pstate: Modify the min_perf calculation in adjust_perf
- callback
-
-Instead of setting a fixed floor at lowest_nonlinear_perf, use the
-min_limit_perf value, so that it gives the user the freedom to lower the
-floor further.
-
-There are two minimum frequency/perf limits that we need to consider in
-the adjust_perf callback. One provided by schedutil i.e. the sg_cpu->bw_min
-value passed in _min_perf arg, another is the effective value of
-min_freq_qos request that is updated in cpudata->min_limit_perf. Modify the
-code to use the bigger of these two values.

-
-Currently, amd_pstate_update_freq passes the hardware perf limits as
-min/max_perf to amd_pstate_update, which eventually gets programmed into
-the min/max_perf fields of the CPPC_REQ register.
-
-Instead pass the effective perf limits i.e. min/max_limit_perf values to

-Subject: cpufreq/amd-pstate: Remove the unnecessary cpufreq_update_policy call
-
-The update_limits callback is only called in two conditions.
-
-* When the preferred core rankings change. In which case, we just need to
-change the prefcore ranking in the cpudata struct. As there are no changes
-to any of the perf values, there is no need to call cpufreq_update_policy()
-
-* When the _PPC ACPI object changes, i.e. the highest allowed Pstate
-changes. The _PPC object is only used for a table based cpufreq driver
-like acpi-cpufreq, hence is irrelevant for CPPC based amd-pstate.
-
-Hence, the cpufreq_update_policy() call becomes unnecessary and can be
-removed.

-Subject: cpufreq/amd-pstate: Fix the clamping of perf values
-
-The clamping in freq_to_perf() is broken right now, as we first typecast
-(read wraparound) the overflowing value into a u8 and then clamp it down.
-So, use a u32 to store the >255 value in certain edge cases and then clamp
-it down into a u8.
-
-Also, use a "explicit typecast + clamp" instead of just a "clamp_t" as the
-latter typecasts first and then clamps between the limits, which defeats
-our purpose.

-During resume it's possible the firmware didn't restore the CPPC request

-
-To fix the issue invalidate the cached value at suspend. During resume use

-Subject: cpufreq/amd-pstate: Overhaul locking
-
-amd_pstate_cpu_boost_update() and refresh_frequency_limits() both
-update the policy state and have nothing to do with the amd-pstate
-driver itself.
-
-A global "limits" lock doesn't make sense because each CPU can have
-policies changed independently.  Each time a CPU changes values they
-will atomically be written to the per-CPU perf member. Drop per CPU
-locking cases.
-
-The remaining "global" driver lock is used to ensure that only one
-entity can change driver modes at a given time.
