seeking beginner-friendly mm bugs to work on

[Dileep Sankhla]

Hello everyone,

Thank you all for improving, enhancing, and maintaining the memory
management subsystem.

I am new to Linux kernel development. Until now, I have only one
contribution that fixes the checkpatch.pl warning. I have also
attempted to create my own 64-bit Unix-like kernel from scratch for
x86-64 PCs. I worked on implementing a physical memory manager and I
also experimented with 64-bit paging.

I want to begin solving a few beginner-friendly bugs. I searched
bugzilla but I don't know which ones are for beginners like me. Could
you guys help me in seeking bugs to work on?

Thanks.

Regards,
Dileep

Hi, Dileep.

I don't think we keep a list of newcomer-friendly bug—instead, we fix them
as they appear.

However, if you want to discover MM bugs, I believe the most effective
way to find them is to extensively test mm-new [1] branch each week.
I’ve discovered and fixed several bugs that way, and the community values
this kind of testing.

Once you're comfortable testing mm-new and discovering bugs, you may
want to start reviewing new patches as well; New code often introduces
bugs, and some issues can pass testing but become obvious (and get caught)
during code review.

There are many bugs reported by the syzkaller fuzzer here:
https://syzkaller.appspot.com/upstream/s/mm

Those with C reproducers are usually easier to fix, although it is not
always the case, at least they are good starters, IMHO.

Hope this helps.
