[L] Change in flashrom[main]: erasure_layout: Fix get_flash_region bug
by Peter Marheine (Code Review) 17 May '24

17 May '24

Attention is currently required from: Aarya, Alexander Goncharov, Anastasia Klimchuk, Nikolai Artemiev. Hello Aarya, Alexander Goncharov, Anastasia Klimchuk, Nikolai Artemiev, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/82393?usp=email to look at the new patch set (#9). The following approvals got outdated and were removed: Verified+1 by build bot (Jenkins) Change subject: erasure_layout: Fix get_flash_region bug ...................................................................... erasure_layout: Fix get_flash_region bug When flash regions are protected, erase could incorrectly erase regions which were meant to be protected by requesting the correct size but using an erase opcode with coarser granularity than desired (for instance using a 16-byte erase command while attempting to erase only 8 bytes). This fixes that by exchanging the nesting of the loops over erase blocks and flash regions. Old: - Select erasefns - Loop over blocks to erase for each selected erasefn - Loop over programmer flash regions within erase block - Erase regions (may fail since selected erasefn will be too big if flash region is smaller than erase block) New: - Loop over programmer flash regions within erase block - Select erasefns within programer flash region - Loop over blocks to erase for each selected erasefn - Erase regions Eraser selection and erasing has also been factored out into a helper function to manage nesting depth. TEST=New test cases pass, whereas some of them fail without the changes to erasure_layout.c BUG=https://ticket.coreboot.org/issues/525 Change-Id: Ic5bf9d0f0e4a94c48d6f6e74e3cb9cccdc7adec9 Co-authored-by: Nikolai Artemiev <nartemiev(a)google.com> Co-authored-by: Anastasia Klimchuk <aklm(a)flashrom.org> Signed-off-by: Nikolai Artemiev <nartemiev(a)google.com> Signed-off-by: Anastasia Klimchuk <aklm(a)flashrom.org> Signed-off-by: Peter Marheine <pmarheine(a)chromium.org> --- M erasure_layout.c M tests/erase_func_algo.c M tests/tests.c M tests/tests.h 4 files changed, 489 insertions(+), 96 deletions(-) git pull ssh://review.coreboot.org:29418/flashrom refs/changes/93/82393/9 -- 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 Gerrit-Project: flashrom Gerrit-Branch: main Gerrit-Change-Id: Ic5bf9d0f0e4a94c48d6f6e74e3cb9cccdc7adec9 Gerrit-Change-Number: 82393 Gerrit-PatchSet: 9 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: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Attention: Alexander Goncharov <chat(a)joursoir.net> Gerrit-MessageType: newpatchset

[S] Change in flashrom[main]: Correct get_flash_region() to use inclusive upper bounds
by Peter Marheine (Code Review) 17 May '24

17 May '24

Attention is currently required from: Aarya, Peter Marheine. Hello Aarya, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/82496?usp=email to look at the new patch set (#2). Change subject: Correct get_flash_region() to use inclusive upper bounds ...................................................................... Correct get_flash_region() to use inclusive upper bounds get_flash_region() emits a struct flash_region, which uses chipoff_t for the start and end addresses of a region. chipoff_t is defined as a valid flash address, so it was wrong to be setting the end address to start + len; this is clearly wrong in the case where there is a single region because setting end to the flash size generates an address that is beyond the end of the chip (due to zero-indexing). This changes the one actual implementation of .get_region in ichspi.c to use inclusive upper bounds, and corrects all callers of get_flash_region() to treat the upper bounds as inclusive. Overall this reduces complexity slightly by removing more downward adjustments by 1 than it needs to add upward adjustments.
