| Summary | 0002416: GNUnet fails to create namespace with wrong names | ||||
| Description | GNUNET_FS_namespace_create() creates a file that stores namespace key. File name == namespace description. If namespace description contains invalid characters (such as '?' on W32), GNUNET_FS_namespace_create() fails and returns NULL. gnunet-fs-gtk_create-pseudonym.c calls GNUNET_FS_namespace_delete() for it immediately, not bothering to check that ns is NULL. Anyway, i think that using arbitrary strings for filenames might be error-prone. Maybe use key hashes or something? On the other hand, they don't have any metadata, and the only things that help one to identify them are their filenames...Normalize them? | ||||
| Tags | No tags attached. | ||||
| I guess using the encoded hash as the namespace filename might be best. Maybe 'struct GNUNET_CRYPTO_ShortHashAsciiEncoded' to get a slightly shorter filename (as the very long filenames sometimes also cause problems on some file systems). | |
| yes, but how are you going to show a list of identities to the user? The files do not have any data other than the key (AFAIK). You need also to add some kind of description to key files. | |
| Sure, I thought the metadata was serialized as well. But that problem would exist either way, as with canonicalization the descriptions would also be garbled. | |
| Ok, went over the code. The 'name' here is clearly supposed to be a valid filename; GNUNET_FS_namespace_create is also used to open an existing namespace file, so the 'name' argument must be a valid filename, otherwise the whole API won't work. Also, changing this will break backwards-compatibility badly. So I think the answer is to restrict the legal characters in gnunet-fs-gtk (and likely gnunet-pseudonym) and of course check for the return value being NULL. | |
| SVN 21978 restricts characters for pseudonym names to alpha-numerical and "_" and "-", which should be pretty safe. (Albeit possibly inconvenient for international users, dealing with non-English characters that are safe for filenames is left as an exercise to the reader ;-).) | |
