| Summary | 0004213: parv[0] usage needs to be fixed | ||||
| Description | Anywhere we're using parv[0], we should use sptr->name or sptr->id. We also need a macro to choose sptr->id over sptr->name if an ID is present (which will be used for the TS6-ish messages). Using parv[0] means we do not have control over what we're sending over the wire, which can desync non-SID servers. This bug must be fully resolved before we can go beta. | ||||

Sledgehammer-like patch to change this. Similar to the checked string operations patch, it will likely introduce at least one bug which we will turn up if we do detailed testing ;) |
|
|
Shouldn't the sledgehammer-like patch use the macro you mentioned? I presume we should use UID everywhere possible? Or does your sledgehammer not provide that capability ;p You can also (upstream) make parv[0] = NULL / 0xDEADBEEF / something other nasty so you can easily catch anyone using it... |
|
|
I'm not nenolod. Anyway, it should definitely use the macro in some cases, which we might want to review. I may amend this patch to do that if I have time. |
|
|
Ok, good :) Don't understand your "I'm not nenolod" though. Perhaps my 'upstream' term confused you? Sorry. I meant setting para[0] to NULL in parse(). Again, if you want a simple way to trace any issues, I'm not saying it's a great idea in other circumstances. |
|
|
Of course. I merely meant that I didn't mention the macro you're talking about at all. |

Done. https://github.com/unrealircd/unrealircd/commit/e8dfb284a1edf3da0bdea230a61ce8a960a2480a https://github.com/unrealircd/unrealircd/commit/0c516abc76341db0aae43bb9870241ceb954eab7 commit e8dfb284a1edf3da0bdea230a61ce8a960a2480a Author: Bram Matthys <[email protected]> Date: Fri Jul 10 12:17:05 2015 +0200 Replace parv[0] with sptr->name. Don't use parv[0] anymore. I went through all 500+ of them by hand as to avoid introducing bugs... we'll see ;) commit 0c516abc76341db0aae43bb9870241ceb954eab7 Author: Bram Matthys <[email protected]> Date: Fri Jul 10 12:29:07 2015 +0200 You can now no longer use parv[0]. Doing so will lead to a crash, this is intentional. Use sptr->name instead. No UnrealIRCd code reads from parv[0] anymore. Perhaps later, after a few stable versions, we'll turn this into something more useful. Or not. But not soon. |
