Hi all,
Commit 20401d1058f3f841f35a594ac2fc1293710e55b9("ipc: replace costly bailout check in sysvipc_find_ipc()" fixes a high cve and optimizes the costly loop by adding a checkpoint, which I think might be a good candidate for the stable branches
What do you mean by "high cve"?
And that feels like it's an artificial benchmark fixup, what real workload benefits from this change?
Standard ipcs end up parsing /proc/sysvipc/*, thus there are real users where the performance of /proc/sysvsem/* matters.
What real users are that? What workload needs that becides monitoring tools?
But:
The performance of the function was bad since 2007, i.e. why is is now urgent? I do not see a bug that must be fixed.
Me either.
thanks,
