Enhancements

• radareorg/radare2@fcf3ad1 : ELF improvement
• radareorg/radare2@17a160c : ELF improvement
• Correct MZ size when bytes_in_last_block = 0 radareorg/radare2#19042 (issue MZ: section size underflow with small file size in header radareorg/radare2#19043): MZ underflow

Finished and rejected

• radareorg/radare2@e3b5991 : see RzUtil: add unit tests for rz_str_ndup/nlen #1419 right now i could not find any issue with those functions, so i'm not backporting
• radareorg/radare2@0ace091 : see Import: Add new CPUs for PPC and honor asm.cpu for asm.arch=ppc.gnu #1278
• radareorg/radare2@acf4693 You can see the changes to tests has been essentially reverted in radareorg/radare2@3fedf80#diff-4966e4f1fa478276b4c6424b2ae54c6216ed6311b8c3b7d43976b71070307236 . The output of r2 and rizin are the same now, so we can skip this.
• radareorg/radare2@0977e61 let's fix this when we encounter the problem. With proper tests as well.
• https://github.com/radareorg/radare2/pull/18483/files some things have already been patched. others i cannot find. i think we can just skip this.
• radareorg/radare2@a0213f0 we can fix our coverity issues ourselves. I think it's safer, easier than trying to backport things happening on a now very different codebase.
• Fix coverity vulnerabilities 2 radareorg/radare2#18521 we can fix our coverity issues ourselves. it's just easier.
• radareorg/radare2@c150dc4 this seems wrong because disassembler_options is a char * and options is a local var on the stack. Anyway, we are fixing this in our own PR.
• radareorg/radare2@57a9926 some small refactoring in cons grep.c. I think we can do that ourselves at some point.
• radareorg/radare2@be3b640 : let's ignore pf for now
• radareorg/radare2@6181e1e : let's ignore pf for now
• radareorg/radare2@42d05b7 : let's skip, we rewrite that part if necessary

Plan 9 binary format

• radareorg/radare2@592e640
• radareorg/radare2@fbfebef
  at this point rzbin plugins are quite different as we have maps to map things, so not sure it's worth backporting. it would be a rewrite of the plugin in other words.
• Implement ssdeep fuzzy hashing algorithm ##hash radareorg/radare2#18490 : I know nothing about this ssdeep algo, but I used https://pypi.org/project/ssdeep/ and I got different results than what expected in the unit tests there. Also, ssdeep library is provided on many distros, so we should probably add the chance to compile with libssdeep instead of our own implementation, if we really want this. Also, probably it requires some adjustments due to the many changes done by @wargio on the hash code. ----- it doesn't seem to be much requested feature. skip given the above.
• Implement slurp:// uri handler plugin ##io radareorg/radare2#18424 (use a separate plugin): same, it doesn't look like it's much requested feature so far. skip.

Enhancements signatures

• radareorg/radare2@0a10c3f
• radareorg/radare2@98150ad
• radareorg/radare2@086038f
• radareorg/radare2@74b8b3c
• radareorg/radare2@00e8fd1
  all skip because signatures were heavily refactored already by wargio.

I don't think porting Coverity fixes makes sense since we have our own Coverity instance, so we could just use it.

[thestr4ng3r]

I would not trust these without tests.

[ret2libc]

@XVilka @thestr4ng3r can we close this? We are not following r2 anymore, I think.

[wargio]

for me is ok to close this.

[XVilka]

Certain changes in ELF parsing are worth packporting.
