bug(hashsum): uutils show no error when providing an invalid hash and passing the option -c and --status

[HackingRepo]

Hi, uutils mainteners

the md5sum utility exits with success in invalid hashes

relunsec@relunsec:~/software/coreutils/target/debug$ echo -n I\'mNotAHash | ./md5sum -c --status
relunsec@relunsec:~/software/coreutils/target/debug$ 

instead of erroing out, while the gnu one errors out correctly

relunsec@relunsec:~/software/coreutils/target/debug$ echo -n I\'mNotAHash | gnumd5sum -c --status
gnumd5sum: 'standard input': no properly formatted checksum lines found
relunsec@relunsec:~/software/coreutils/target/debug$

@sylvestre hashsum was already removed. Title should have cksum family or *sum.

[HackingRepo]

no hashsum, means @oech3 all hash sum utilities

[oech3]

No. We previously had a multi-call binary only for *sum which is already removed.

I can work on this. I plan to add a regression test for malformed checksum input with --check --status, then update the shared checksum validation path so an input with no valid checksum lines returns a failure status while remaining silent.

[Lovlace777]

I retested the exact unterminated input against current main: md5sum exits with status 1 and produces no output under --status. PR #12622 already changes the related malformed-status diagnostic behavior, so I will not open a duplicate PR here.

[HackingRepo]

yes, @Lovlace777 but we need tests for other utilities now only b2sum have tests, md5sum and sha256sum and others need have test, the pr title referenced needs to be updated and add other checksum utilities test

[oech3]

No need. They shares code base via checksum_common

[HackingRepo]

but just the pr title and pr description, @oech3 needs be updated, for mention hashsum which means all sum utilities
