| | | | | | | | | | | | | | | | | | | | | | | | drop the _iov suffix from most encryption- and decryption-related functions. The enc_provider encrypt and decrypt functions take IOVs, as do the enctype entries in etypes.c, and there are no separate encrypt_iov or decrypt_iov functions. aead_provider is gone. Enctype functions now take pointers to the enctype entry instead of pointers to the enc/hash/aead providers; this allows dk_encrypt and dk_decrypt to be polymorphic in the length function they use now that AES and DES3 can't differentiate by aead provider. aes_string_to_key needed to be moved into the krb/ fold for this since it's an enctype function; it was duplicated between builtin/ and openssl/ before. This leaves openssl/aes empty; the build system currently demands that all modules have the same directory structure, so the directory and Makefile will stick around for now. Three separate copies of the derive_random logic are also now consolidated into one. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23444 dc483132-0cff-0310-8789-dd5450dbe970

* fix slow behavior on Mac OS X with link-local addressesKen Raeburn2009-12-032-20/+96
| | | | | | | | | | | | | | | | | | | | | | | | | When using my previous patch, if a local hostname like "foobar.local" is looked up, you may get back a link-local IPv6 address. However, the KDC seems to be unable to respond from that address, resulting in a ~1s delay for each KDC exchange while waiting for the client to fail over to another address (in my case, another IPv6 address). Create a new object for holding whatever auxiliary information might be needed to properly transmit the response to the client. Currently, that only means the interface index number under IPv6. Fill it in on receipt, always; copy it back to the pktinfo structure when transmitting, ONLY if the local source address is link-local. If an error occurs while transmitting the reply, print both the remote destination address and the local source address. Use getnameinfo instead of inet_ntop. Apply the same changes to kadmind, to keep the versions of network.c more or less in sync. ticket: 6591 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23440 dc483132-0cff-0310-8789-dd5450dbe970
* allow testing even if name->addr->name mapping doesn't workKen Raeburn2009-12-033-13/+25
| | | | | | | | | | | | | | | Many of the tests are set up to fail if the local hostname can't be mapped to an address and back to a name again. If the name results in an address, and we can get a fully-qualified name or something that looks like it, though, we should be able to just go ahead and run some tests. This is also closer to the current behavior of sname_to_principal when reverse DNS is enabled. ticket: 6590 git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@23439 dc483132-0cff-0310-8789-dd5450dbe970
