Also maybe drop the last word (error). I think "to prevent underflow" is enough. And then it will fit into char limit. -- To view, visit https://review.coreboot.org/c/flashrom/+/62764 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I5921cc571f3dca5188ca1973dba6ececbcbe2f39 Gerrit-Change-Number: 62764 Gerrit-PatchSet: 12 Gerrit-Owner: Light <aarya.chaumal(a)gmail.com> Gerrit-Reviewer: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Nico Huber <nico.h(a)gmx.de> Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-Attention: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Attention: Light <aarya.chaumal(a)gmail.com> Gerrit-Comment-Date: Sat, 26 Mar 2022 08:21:19 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Gerrit-MessageType: comment

So in initial version the loop starts with j=10, after this patch it starts with j=12. I understand about underflow and undefined behaviour, looks like it's correct to start loop with j=12. I am curious, what was printed for Sunrise Point for j=10,11 , was that printing garbage? Otherwise, looks good!

Change in flashrom[master]: flashrom.c, sfdp.c: Initialize dynamically allocated memory using calloc

Please visit https://review.coreboot.org/c/flashrom/+/62747 to look at the new patch set (#12). Change subject: flashrom.c, sfdp.c: Initialize dynamically allocated memory using calloc ...................................................................... flashrom.c, sfdp.c: Initialize dynamically allocated memory using calloc In flashrom_image_write variables curcontents and oldcontents are dynamically allocated using malloc. These could remain uninitialized and when later used in need_erase could result in undefined behaviour. Similar reasoning for variables hbuf, hdrs, tbuf in function prob_spi_sfdp. So allocate them using calloc to initialize them to zeroes. Also, copy "FLASHROM BUG!" to detect future bugs.
