This patchset aims at updating the Linux kernel to 5.15.85, given that
the last release we shipped dates back a while ago. However, its primary
purpose is to backport some kernel changes recently made by Michael in
IPFire 3.x, whenever bringing these to the IPFire 2.x userbase is sensible
and/or feasible.
Patch descriptions are copy & past'ed from their IPFire 3.x counterparts,
which are referred to by their commit IDs in ipfire-3.x. Due to different
hardware situation as well as architecture maturity (this particularly
affects ARM), not all changes could be backported 1:1 or to a near-complete
extend.
Feedback is particularly appreciated regarding the last commit, which aims
at aligning the ARM kernel configuration files to the x86_64 one. Since
no real ARM hardware is at the author's disposal, this alignment has to be
taken with a pinch of salt.
As far as benchmarks are concerned, a 5.15.85 x86_64 kernel booted in an
IPFire 2.x VM on the basis of Core Update 172 introduced the following changes
in file size:
Location Before After
-------------------------------------------
/boot 48M 53M (+ 5)
/lib/modules 58M 71M (+13)
ISO 373M 394M (+21)
Contrary to its documentation, enabling the GCC stackleak plugin (which
is the current setting in IPFire 3.x as well) neither brought a notable
compile time increase, nor does it seem to slow down runtime operations
significantly. More thorough tests, especially on physical machines, are
however, yet to come.
