gcrypt: Return key size in bytes.

The crypto API requires get_asymmetric_key() to return the size of
the RSA key in bytes on success.  The return value is evaluated in
populate_user_list() where keys which are too short to encrypt a

However, for ASN.1 keys, the gcrypt implementation returned the number
of *bits* instead. This caused para_server to accept keys which are

afs: Fix long-standing bug in add command.

Before the add command handler adds a given audio file to the database
it asks the afs process to check whether the file already exists.

The afs process looks for rows in the audio file table with path
and/or hash identical to the given file. If a match is found a
pointer to the matching row is passed from afs to the command handler.
The get_row_pointer_from_result() helper is then called by the command
handler to extract the row pointer from the result returned by afs.

However, this helper incorrectly dereferenced the pointer which caused
the command handler to examine an address rather than the content of
the address to tell whether the file already exists and whether path
or content has changed. This could lead to changed/moved files being
ignored as well as existing files being added again.

libao: Avoid segfault on com_cycle.

Executing the cycle command while the ao writer is active can lead to
a segmentation fault because kill_all_decoders() removes the buffer
tree node of the ao writer but leaves its child node alive.

This patch changes kill_all_decoders() to kill the receiver node only
while leaving all other nodes alone, removing the assumption that
the set of filter nodes and writer nodes are the only nodes in the
buffer tree. This assumption used to be true but became false with
the merge of the ao writer which has two buffer tree nodes.

It is enough to kill only the receiver node as all other nodes will
eventually notice that their parent node no longer exists and exit
shortly thereafter.

Add support for ssh-rsa keys.

This allows to use standard ssh keys (that is, keys generated with
ssh-keygen) for the challenge/response authentication method of
paraslash. Only RSA keys without password protection are supported
at the moment.

Since we want that both openssl and ssh keys just work, we introduce
the helper function is_ssh_rsa_key(). It looks at the first few bytes
of the key to decide which type of public key we have. For openssl
keys, we just call openssl's EVP_PKEY_get1_RSA() and be done. Private
keys generated by ssh-keygen do not differ from keys generated by
"openssl rsa" and need no special treatment either.

However, public ssh rsa keys are stored differently, as an uuencoded
byte stream. So this patch adds functions that decode a given buffer
via base64 or uudecode. The two rsa public parameters (modulus and
exponent) are then read from the decoded buffer using BN_bin2bn().
