[Openipmi-developer] [PATCH] treewide: const qualify ctl_tables where applicable
|
From: Joel G. <joe...@ke...> - 2025-01-09 13:17:10
|
Add the const qualifier to all the ctl_tables in the tree except the
ones in ./net dir. The "net" sysctl code is special as it modifies the
arrays before passing it on to the registration function.
Constifying ctl_table structs will prevent the modification of
proc_handler function pointers as the arrays would reside in .rodata.
This is made possible after commit 78eb4ea25cd5 ("sysctl: treewide:
constify the ctl_table argument of proc_handlers") constified all the
proc_handlers.
Created this by running an spatch followed by a sed command:
Spatch:
virtual patch
@
depends on !(file in "net")
disable optional_qualifier
@
identifier table_name;
@@
+ const
struct ctl_table table_name [] = { ... };
sed:
sed --in-place \
-e "s/struct ctl_table .table = &uts_kern/const struct ctl_table *table = \&uts_kern/" \
kernel/utsname_sysctl.c
Signed-off-by: Joel Granados <joe...@ke...>

This treewide commit builds upon the work Thomas began a few releases
ago [1], where he laid the groundwork for constifying ctl_tables. We
implement constification throughout the tree, with the exception of the
ctl_tables in the "net" directory. Those are special in that they treat
the ctl_table as non-const but we can take them at a later point.
Upstreaming:
===========
It is late in the release cycle, but I'm hopeful that we can get this
in for the upcoming merge window and this is why:
1. We don't use linux-next: As with previous treewide changes similar to
this one [1], we avoid using linux-next in order to avoid unwanted
merge conflicts
2. This is a non-functional change: which lowers the probability of
unforeseen errors or regressions.
3. It will have at least 2 weeks to be tested/reviewed: The PULL should
be sent at the end of the merge window, giving it at least 2 weeks.
And if there are more release candidates after rc6, there will be
more time.
Testing:
========
1. Currently being tested in 0-day
2. sysctl self-tests/kunit-tests
Reduced To/Cc:
==============
b4 originally gave me 200 ppl that this should go out to (which seems a
bit overkill from my point of view). So I left the mailing lists and
reduced the To: the ppl previously involved in the effort and sysctl
maintainers. Please tell me if I missed someone important to the
constification effort.
Comments are greatly appreciated.
Specially interested in any specifics from @Thomas and @kees
Best
