+Subject: [PATCH 01/44] irqbalance-ui: check if using a negative index of
+ buffer
+
+A negative index will be used when recv() fails, which is unexpected for
+the data buffer. The issue was found by Static Application Security
+Testing (SAST), which is a potential weakness.
+
+This patch will check the negative index before data buffer referencing.

+Subject: [PATCH 02/44] Check fflush() return value
+
+Since fprintf() may buffer output, as noted in 470a64b19062, fclose()'s
+error value was also being checked for the write errors.  However in
+8d7c78304fb9 an fflush() was added in between meaning that these
+buffered write errors were again unchecked.  Some actual errors were
+not being logged, in my case -ENOSPCs.
+
+Make the fclose and fflush branches look similar.

+Subject: [PATCH 06/44] meson: move build files to repository root
+
+Per the README and github ticket discussion, the purpose of having it in
+contrib/ is to gauge community interest. This interest has now been
+expressed by several parties, so that interest is certainly there.
+
+Let's move it to a more discoverable location. This has two benefits:
+
+- usability. If various parties intend to use it, then it is easier to
+  do so from the repository root rather than cd'ing into a subdir.
+
+- discoverability. At least Gentoo didn't initially realize it existed,
+  since it wasn't in the repository root, but switched after realizing.
+  It seems reasonable that other redistributors, too, would be
+  interested in evaluating its use but hadn't previously noticed the
+  option.

+Subject: [PATCH 08/44] meson: drop redundant install_man() options
+
+It is unnecessary to set the install directory for manpages, since meson
+infers this from the file extension and installs *.1 manpages to mandir
+in the man1 section for you.
+
+It is also unnecessary to tag them as "en" because that is the
+default... it is likewise unnecessary to tag them with manual file
+permissions since the default 644 permission is also the overridden one.

+
+Indicate the minimum required version of meson. Version 0.47 (released

+curses dependency wrapper. This just lets meson know that, so it
+can:

+Subject: [PATCH 22/44] Wrap migrate_irq in a higher level utility function
+
+Add migrate_irq_obj and replace existing migrate_irq calls with calls to
+the new function.  migrate_irq_obj takes source and destination
+topo_obj's instead of interrupt lists so as to factor out updating of
+the load on the destination cpu and of info->asssigned_obj.
+
+Pass NULL as destination to move irq to rebalance_irq_list.
+
+Drop the unneeded force_irq_migration.

+Subject: [PATCH 23/44] Track IRQ "slots" count per CPU to avoid overflowing
+
+There are situations where irqbalance may try to migrate large numbers of
+IRQs to a topo_obj, there's no upper bound on the number as the
+placement logic is based on load mainly.  The kernel's irq bitmasks limit
+the number of IRQs on each cpu and if more are tried to be migrated, the
+write to smp_affinity returns -ENOSPC.  This confuses irqbalance's
+logic, the topo_obj.interrupts list no longer matches the irqs actually
+on that CPU or cache domain, and results in floods of error messages.
+See https://github.com/Irqbalance/irqbalance/issues/303 for details.
+
+For an easy fix, track the number of IRQ slots still free on each CPU.
+We start with INT_MAX meaning "unknown" and when we first get a -ENOSPC,
+we know we have no slots left.  From there update the slots count each
+time we migrate IRQs to/from the CPU core topo_obj.  We may never see an
+-ENOSPC and in that case there's no change in current logic, we never
+start tracking.
+
+This way we don't need to know ahead of time how many slots the kernel
+has for each CPU.  The number may be arch specific (it is about 200 on
+x86-64) and is dependent on the number managed IRQs kernel has
+registered, so we don't want to guess.  This is also more tolerant to
+the topo_obj.interrupts lists not matching exactly the kernel's idea of
+each irq's current affinity, e.g. due to -EIO errors in the smp_affinity
+writes.
+
+For now only do the tracking at OBJ_TYPE_CPU level so we don't have to
+update slots_left for all parent objs.
+
+Th commit doesn't try to stop an ongoing activation of all the IRQs
+already scheduled for moving to one cpu, when that cpu starts returning
+ENOSPC.  We'll still see a bunch of those errors in that iteration.
+But in subsequent calculate_placement() iterations we avoid assigning
+more IRQs to that cpu than we were able to successfully move before.

+
+It is unexpected because irqbalance have successfully returned the

+
+A error message of 'libcap-ng used by "/usr/sbin/irqbalance" failed dropping
+bounding set due to not having CAP_SETPCAP in capng_apply' is noticed.
+
+Previously a similar issue[1] has been fixed by the following commit:
+
+    efab272 Drop CapabilityBoundingSet from irqbalance service
+    43751df drop NoNewPrivs from irqbalance service
+
+in which, CapabilityBoundingSet and NoNewPrivs parameters are dropped
+from the irqbalance.service, and get restored by the following commit
+later:
+
+    a99b604 Set additional systemd options for service
+
+So this patch will not do the dropping again, but add CAP_SETPCAP to
+CapabilityBoundingSet instead.

+Subject: [PATCH 44/44] Use EPERM instead of EIO when try setting irq affinity
+ fails
+
+Kernel commit eb29369fa543e ("genirq/proc: Change the return value for
+set affinity permission error") changed the error number from EIO to
+EPERM when a specific irq failed to set affinity from userspace.
+
+In addition, users have complained about EIO is misleading when
+setting affinity fails, however it just meaning "user cannot set
+affinity", so EPERM is better for that.
+
+This patch will follow the kernel change, to unify the behaviour of
+irqbalance from the kernels which have not integrated the kernel
+commit mentioned above.

-
-For pairs 1, 2, 3, 8, 9, 10, simply change background index to -1.
-Keep pair 4, but enable the 'bold' attribute for text to improve
-legibility. For pair 5 (white on red) use default foreground, and
-instead of pair 6 (red on white) use reverse of pair 5 with bold.
-
-This substantially improves legibility of the UI on a terminal
