When seeing a message
virNetSASLContextCheckIdentity:146 : SASL client admin not allowed in whitelist
it isn't immediately obvious that 'admin' is the identity
being checked. Quote the string to make it more obvious
The libvirt coding standard is to use 'function(...args...)'
instead of 'function (...args...)'. A non-trivial number of
places did not follow this rule and are fixed in this patch.

Any time we have a string with no % passed through gettext, a
translator can inject a % to cause a stack overread. When there
is nothing to format, it's easier to ask for a string that cannot
be used as a formatter, by using a trivial "%s" format instead.
In the past, we have used --disable-nls to catch some of the
offenders, but that doesn't get run very often, and many more
uses have crept in. Syntax check to the rescue!
The syntax check can catch uses such as
virReportError(code,
_("split "
"string"));
by using a sed script to fold context lines into one pattern
space before checking for a string without %.
This patch is just mechanical insertion of %s; there are probably
several messages touched by this patch where we would be better
off giving the user more information than a fixed string.

When trying to use any SASL authentication for TCP sockets by
setting auth_tls = "sasl" in libvirtd.conf on server side, the
client will hang because of the sasl session relocking other than
dropping the lock when exiting virNetSASLSessionExtKeySize()
* src/rpc/virnetsaslcontext.c: virNetSASLSessionExtKeySize drop the
lock on exit
Detected by Coverity. We want to compare the result of fnmatch 'rv',
not our pre-set return value 'ret'.
* src/rpc/virnetsaslcontext.c (virNetSASLContextCheckIdentity):
Check correct variable.
On RHEL 5, with gcc 4.1.2:
rpc/virnetsaslcontext.c: In function 'virNetSASLSessionUpdateBufSize':
rpc/virnetsaslcontext.c:396: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
* src/rpc/virnetsaslcontext.c (virNetSASLSessionUpdateBufSize):
Use a union to work around gcc warning.
The virNetSASLContext, virNetSASLSession, virNetTLSContext and
virNetTLSSession classes previously relied in their owners
(virNetClient / virNetServer / virNetServerClient) to provide
locking protection for concurrent usage. When virNetSocket
gained its own locking code, this invalidated the implicit
safety the SASL/TLS modules relied on. Thus we need to give
them all explicit locking of their own via new mutexes.
* src/rpc/virnetsaslcontext.c, src/rpc/virnettlscontext.c: Add
a mutex per object
This provides two modules for handling SASL
* virNetSASLContext provides the process-wide state, currently
just a whitelist of usernames on the server and a one time
library init call
* virNetTLSSession provides the per-connection state, ie the
SASL session itself. This also include APIs for providing
data encryption/decryption once the session is established
* src/Makefile.am: Add to libvirt-net-rpc.la
* src/rpc/virnetsaslcontext.c, src/rpc/virnetsaslcontext.h: Generic
SASL handling code
