Hello build bot (Jenkins), Nico Huber, Edward O'Callaghan, Angel Pons, Anastasia Klimchuk,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/flashrom/+/62643
to look at the new patch set (#11).
Change subject: writeprotect.c: refactor and fix wp_mode functions
......................................................................
writeprotect.c: refactor and fix wp_mode functions
This is a follow up on commit 12dbc4e04508aecfff53ad95b6f68865da1b4f07.
Use a lookup table in get_wp_mode() and drop the srp_bit_present check,
since a chip without SRP is just FLASHROM_WP_MODE_DISABLED.
Add a srp_bit_present check to set_wp_mode() if the mode requires it.
BUG=b:182223106
BRANCH=none
TEST=flashrom --wp-{enable,disable,status} on AMD dut

PS10, Line 12: since a chip without SRP is just FLASHROM_WP_MODE_DISABLED
Just to double-check, chip without SRP/SRL will have
bits->srp = 0 and bits->srl = 0 without errors, right?

PS36, Line 10: and uses it support
Maybe instead "and uses it support" -> "and uses the framework to support".
File linux_mtd.c:
https://review.coreboot.org/c/flashrom/+/61897/comment/b0973450_a51127f7
PS36, Line 380: if ((cfg->range.len == 0) != (cfg->mode != FLASHROM_WP_MODE_DISABLED)) {
: return FLASHROM_WP_ERR_OTHER;
: }
Please help me, I spent some time staring at the code, also reading the comment above and commit message. It seems to me that comment matches the commit message, but the code does not? what I am missing?
Testing info from commit message, first case:
flashrom --wp-enable --wp-range <non-empty> succeeds
non-empty range makes `cfg->range.len == 0` -> false
--wp-enable makes `cfg->mode != FLASHROM_WP_MODE_DISABLED` -> true
So the condition becomes `false != true` -> true -> so it returns error?
But commit messages says it succeeds?
What I am missing? :)

PS3, Line 9: return a non-negative value for

> This could not be intentional. […]
Well that is exactly why I was wondering if it was intentional? i.e., to fail if there is no `open()` mocked in a test.

PS6, Line 77: wrap_open_and_friends
> open_state in not used when open != NULL (this function returns from within this if case)
That is what I mean by "unexpected behavior" as `open_state` being non-NULL implies a builtin version of `open()` while `open` being non-NULL implies to use an explicit `open()` implementation.
This function maybe needs a comment.
