Modules fixes for 6.16-rc6
This includes 2 fixes: one introduced in the current release cycle (v6.16-rc1)
and another introduced back in v6.4-rc1. Both have been in linux-next since
next-250701 and have passed the modules ci tests using kdevops. Finally, as Petr
and Luis mentioned in previous pull requests, add myself (Daniel Gomez) to the
list of modules maintainers.
The first was reported by Intel's kernel test robot, and it addresses a crash
exposed by Sebastian's commit c50d295c37f2 ("rds: Use nested-BH locking for
rds_page_remainder") by allowing relocations for the per-CPU section even if it
lacks the SHF_ALLOC flag. Petr and Sebastian went down to the archive history
(before Git) and found the commit that broke it b3b91325f3c7 ("Don't relocate
non-allocated regions in modules.").
The second fix, reported and fixed by Petr (with additional cleanup), resolves a
memory leak by ensuring proper deallocation if module loading fails. We couldn't
find a reproducer other than forcing it manually or leveraging eBPF. So, I
tested it by enabling error injection in the codetag functions through the error
path that produces the leak and made it fail until execmem is unable to allocate
more memory.
