Passing NULL as dest_realm for cli_session_setup_spnego() was
always using our own realm (as for a NetBIOS name). Change this
to look for the mapped realm using krb5_get_host_realm() if
the destination machine name is a DNS name (contains a '.').
Could get fancier with DNS name detection (length, etc.) but
this will do for now.

The destname malloc size was not taking into account the 1 extra byte
needed if a string without a leading '/' was passed in and that slash
was added.
This would cause the '\0' byte to be written past the end of the
malloced destname string and corrupt whatever heap memory was there.
This problem would be hit if a share name was given in smb.conf without
a leading '/' and if it was the exact size of the allocated STRDUP memory
which in some implementations of malloc is a power of 2.
Normally clistr_push_fn() can depend upon cli->outbuf being
initialized by negprot and sessionsetup packets, and cli->outbuf[smb_flgs2] being
correctly set with FLAGS2_UNICODE_STRINGS when cli_setup_packet() is called. When
all the sessionsetups are async, then cli_setup_packet() is never called, the async
code uses cli_setup_packet_buf() - which initializes the allocated async buffer,
not the cli->outbuf one. So the first time clistr_push_fn() is called is from
libsmb/clidfs.c:cli_dfs_get_referral(), just after the connection and tconX.
In this case cli->outbuf has never been initialized, and cli->outbuf[smb_flgs2] = 0
so the DFS query pushes ASCII on the wire, which is not what we want :-).
Remove the dependency on cli->outbuf[smb_flgs2] in clistr_push_fn(), and
fake up a SVAL(cli->outbuf, smb_flg2) value using cli_ucs2(cli) function
instead, which has been initialized. We only care about the FLAGS2_UNICODE_STRINGS
bit anyway.
I don't think this is an issue for 3.5.0 as the sessionsetup is still
synchronous there, but Volker PLEASE CHECK !

A combination patch from Johannes Poehlmann <johannes@lst.de> and
Jeremy. Fix the return codes from smb_download_file() and smb_download_dir().
Jeremy.
Fix suggested by Andy Hanton <andyhanton@gmail.com>. The LOGIN_CACHE
struct contains two time_t entries, but was being written to and
read from via tdb_pack/tdb_unpack functions using explicit 32-bit int specifiers.
This would break on machines with a 64-bit time_t. Use correct int
sizes for tdb_pack/tdb_unpack.
We have to fix this properly before 2037 :-).
Jeremy.
Only works on Linux kernels 2.6.26 and above. Grants CAP_KILL capability
to allow Linux threads under different euids to send signals to each other.
Jeremy.
Disable this by setting the environment variable LIBSMBCLIENT_NO_CCACHE, which
has the advantage over an smb.conf option to be easily settable per
application.
Can we enable this by default? This would be a change in behaviour, but this
feature is just too cool for everyone to catch up in the apps.
The patch would be
In order to add --use-ccache to net, I added another "bool opt_ccache;" to
struct net_context. popt did not like this, it took a while to figure out why.
Popt has the lines
/* XXX Check alignment, may fail on funky platforms. */
if (arg == NULL || (((unsigned long)arg) & (sizeof(*arg)-1)))
return POPT_ERROR_NULLARG;
The "bool opt_ccache;" was not aligned anymore...
