[XS] Change in flashrom[main]: Add clarification to struct flash_region on chipoff_t
by Peter Marheine (Code Review) 28 May '24

28 May '24

Peter Marheine has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/82677?usp=email ) Change subject: Add clarification to struct flash_region on chipoff_t ...................................................................... Add clarification to struct flash_region on chipoff_t Although chipoff_t is fairly clearly documented on its own, it seems fairly frequent that developers will treat the end address of a flash region as an exclusive upper bound rather than the inclusive one it should be; for example CB:82496 fixes an incorrect use that affected multiple sites, and CB:73571 stemmed from a similar cause. Add a clarifying comment to call attention to this, to help programmers avoid making similar mistakes in the future.

[L] Change in flashrom[main]: erasure_layout: Fix get_flash_region bug

( https://review.coreboot.org/c/flashrom/+/82393?usp=email ) Change subject: erasure_layout: Fix get_flash_region bug ...................................................................... Patch Set 13: (4 comments) Patchset: PS13: I got some last moment thoughts... File erasure_layout.c: https://review.coreboot.org/c/flashrom/+/82393/comment/afce5561_615cb6d6?us… : PS13, Line 368: for (unsigned int addr = region_start; addr <= region_end; addr += len) { I looked at this loop and got a bit suspicious. Specifically, will it properly get to the other side of protected region and continue after the end of protected region? And I really only now thought about it. And now I am realising that current test cases do not cover this case, when protected region somewhere in the middle of the chip (which is always the case in real life). The unit test has protected region which ends right at the end of chip memory :\ To represent what I am thinking about now, it could be e.g. between bytes 6-12, and we want to make sure bytes 13-15 are also processed. What do you think? I can try modify the test cases, maybe at the end of this week. Or if you want you can?

[…] I forgot what exactly was on my mind when I was asking , sorry :( Probably I was confused because parameterized tests are initialized in a loop, and non-param with a memcpy.

Which might also need to adjust layout regions. It's easier to have the same protected region, and variations of layout regions in every test case. -- To view, visit https://review.coreboot.org/c/flashrom/+/82393?usp=email To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: Ic5bf9d0f0e4a94c48d6f6e74e3cb9cccdc7adec9 Gerrit-Change-Number: 82393 Gerrit-PatchSet: 13 Gerrit-Owner: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Reviewer: Aarya <aarya.chaumal(a)gmail.com> Gerrit-Reviewer: Alexander Goncharov <chat(a)joursoir.net> Gerrit-Reviewer: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Attention: Aarya <aarya.chaumal(a)gmail.com> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Attention: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Attention: Alexander Goncharov <chat(a)joursoir.net> Gerrit-Comment-Date: Mon, 27 May 2024 12:59:38 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Comment-In-Reply-To: Peter Marheine <pmarheine(a)chromium.org>
