Use 2-factor multiplication argument form kcalloc() instead
of kzalloc().
Also, it is preferred to use sizeof(*pointer) instead of
sizeof(type) due to the type of the variable can change and
one needs not change the former (unlike the latter).

Hi everyone,
This patch seems to be lost. Gustavo reviewed it on January 15, 2024
but the patch has not been applied since.

This looks correct to me. I can pick this up if no one else snags it?

I guess my original reply didn't make it out, I don't see it in the
archives.
My objections were:
1. The original code is more readable to me than the proposed
replacement.
2. The original code has worked since introduced in 2012. Nobody has
touched it since, presumably it's fine.
3. I don't have the hardware and thus no way of validating the proposed
changes.
So what is the benefit of me accepting this patch? We have had several
regressions in these conversions. Had one just last week, almost
identical in nature to the one at hand.
I am all for fixing code which is undergoing active use and development.
But I really don't see the benefit of updating a legacy driver which
hasn't seen updates in ages. Why risk introducing a regression?

I guess this is a style preference. I find the proposed easier to read.
It also removes lines while doing it. :)

The code itself is fine unless you have a 32-bit system with a malicious
card, so yeah, near zero risk.

This is kind of an ongoing tension we have between driver code and
refactoring efforts. And this isn't a case where we can show identical
binary output, since this actively adds overflow checking via kcalloc()
internals.

People are working through large piles of known "weak code patterns"
with the goal of reaching 0 instances in the kernel. Usually this is for
ongoing greater compiler flag coverage, but this particular one is
harder for the compiler to warn on, so it's from Coccinelle patterns.

I see a common pattern where "why risk introducing a regression?" gets
paired with "we can't test this code". I'm really not sure what to do
about this given how much the kernel is changing all the time.
In this particular case, I guess all I can say is that it is a trivially
correct change that uses a more robust API and more idiomatic allocation
sizeof()s (i.e. use the sizeof() of what is being allocated, not a
potentially disconnected struct name).

If a change is "trivially correct" then the proof is trivial too.
Based only on what you wrote above, omitting the overflow check would give
binary equivalence. That validates the driver change (for hardware you
lack).
But, since a build without the overflow check must contain a second
change, you must validate that change too by showing that kcalloc()
internals still work for every other caller. (You do this using hardware
you have.)

Well, no actually zero: we assume plugged in hardware to operate
correctly (had this argument in the driver hardening thread a while
ago), but in this particular case you'd have to have a card with a very
high number of ports, which would cause kernel allocations to fail long
before anything could introduce an overflow of sizeof(struct csio_lnode
*) * hw->num_lns.

That's because we keep having cockups where we accept so called "zero
risk" changes to older drivers only to have people with the hardware
turn up months to years later demanding to know why we broke it.
Security is about balancing risks and the risk here of a malicious
adversary crafting an attack based on a driver so few people use (and
given they'd have to come up with modified hardware) seems equally
zero.

Overflow checking which is unnecessary as I showed above.

We understand the problem and we're happy to investigate and then
explain why something like this can't be exploited, so what's the issue
with adding it to the exceptions list given that, as you said, it's
never going to be compiler detected?

Well, it's a balance of risks, but given that there's zero chance of
exploitation of the potential overflow, it would seem that balance lies
on the side of not risking the regression. I think if you could
demonstrate you were fixing an exploitable bug (without needing
modified hardware) the balance would lie differently.

Which is somewhat similar to the statement other people made about the
strncpy replacement which eventually turned out to cause a problem.

Then it should be safe to add an equivalent assertion. E.g.
BUG_ON(hw->num_lns > X) where X was derived either from knowledge of the
hardware or from some known-safe kalloc() limit. Though I wonder whether
BUG_ON() is the best way to encode preconditions for the benfit of static
checkers...
