As we use talloc_tos() in inner libsmbclient/ functions more and more, we need
to make sure not to create memleaks by not free'ing talloc stackframes. This
patch wraps all calls in libsmbclient.c that are publically exported into a
talloc_stackframe()/talloc_free() pair.
Jeremy, Derrell, can you check this?
Thanks,
Volker
This is a different fix than the bug reporter (Evgeniy Dushistov
<dushistov at mail.ru>, thanks!) created, but it lives without the boolean
status variable. Untested so far, but I can not add attachments to bugs right
now. But to me this looks really obvious.
zero_addr(&ss). All current uses were always of the
AF_INET form, so simplify the call. If in the future
we need to zero an addr to AF_INET6 this can be
done separately.

to struct sockaddr_storage in most places that matter (ie.
not the nmbd and NetBIOS lookups). This passes make test
on an IPv4 box, but I'll have to do more work/testing on
IPv6 enabled boxes. This should now give us a framework
for testing and finishing the IPv6 migration. It's at
the state where someone with a working IPv6 setup should
(theorecically) be able to type :
smbclient //ipv6-address/share
and have it work.
Jeremy.
IPv6 in winbindd, but moves most of the socket functions that were
wrongly in lib/util.c into lib/util_sock.c and provides generic
IPv4/6 independent versions of most things. Still lots of work
to do, but now I can see how I'll fix the access check code.
Nasty part that remains is the name resolution code which is
used to returning arrays of in_addr structs.

device. The device resets a NBT connection on port 139 when it receives a
NetBIOS keepalive request. That request should be supported when NetBIOS is
in use; Windows is behaving badly.
libsmbclient needs a way to determine if a connection is still alive, and
was using a NetBIOS keepalive request if port 139 was in use (on the
assumption that it was probably NBT), and getpeername() when port 139 was
not being used (assuming naked transport).
This patch simplifies the code by exclusively using getpeername() to check
whether a connection is still alive. The NetBIOS keepalive request is
optional anyway (with preference being given to using TCP mechanisms for the
same purpose), so this should be both simpler and more reliable.

the request, presumably due to the PROTECTED flag not being set. Setting
that flag (in make_sec_desc()) has much wider implications than just to
libsmbclient, so instead of modifying that, we'll remove security
descriptors by setting the number of ACEs to zero. At some point, we might
want to look into whether we should actually be setting the PROTECTED flag
in the DACL.

prs_mem_free() is not the function to be called to free memory allocated by
prs_alloc_mem(). I've added a comment so others may not get bitten too.
- Remove incorrect memory free calls added yesterday to replace SAFE_FREE.
The memory is actually now on a talloc context, so gets freed by the caller
when that context is freed. We don't need to free it iternally.

incremented too far in some circumstances. In these cases, only the first
of multiple concatenated strings would be seen.
- Working on bug 4649 pertaining to delete an ACL, this fixes the reported
crash. It appears to have been an incomplete switchover from malloc to
talloc, as the memory was still being freed with SAFE_FREE.
Deleting ACLs still doesn't work. Although a valid request is sent to the
server and a SUCCESS response is returned, the method that's used in
libsmbclient for deleting ACLs seems to be incorrect. In looking at the
samba4 torture tests, it appears that we should be turning on the INHERIT
flag if we want to delete the ACL. (I could use some assistance on the
proper flags to send, from anyone familiar with this stuff.)
- Apply patch from SATOH Fumiyasu to fix bug 4750. smbc_telldir_ctx() was not
returning a value useful to smbc_lseekdir_ctx().
Derrell
attempts to set attributes to fail.
- I also noticed that missing attributes were setting an invalid return string
by getxattr(), e.g. if there was not group, the return string had "GROUP:;"
instead of excluding the GROUP attribute entirely as it should. The big
problem with the way it was, is that the string could not then be passed to
setxattr() and parsed.
process deep dfs links (ie. links that go to non root
parts of a share). Make the directory handling conanonical
in POSIX and Windows pathname processing.
dfs should not be fully working in client tools. Please
bug me if not.
Jeremy.
- Should fix bug 4115 (but needs confirmation from OP). If the kerberos use
flag is set in the context, then also pass it to smbc_attr_server for use by
cli_full_connection()
- Should fix bug 4309 (but needs confirmation from OP). We no longer send a
keepalive packet unconditionally. Instead, we assume (yes, possibly
incorrectly, but it's the best guess we can make) that if the connection is
on port 139, it's netbios and otherwise, it isn't. If netbios is in use, we
send a keepalive packet. Otherwise, we check that the connection is alive
using getpeername().
still doesn't compile with immediate structures and the
NTSTATUS/WERROR separation, as there are still several places where
the two error types are mixed up. I haven't fixed those as they
require decisions about the rpcclient code that I really don't want to
get into (the error handling there is a mess)
So samba3 compiles now, but only becaise HAVE_IMMEDIATE_STRUCTURES is
not used (look for HAVE_IMMEDIATE_STRUCTURES_XX_DISABLED)
* autogenerate lsa ndr code
* rename 'enum SID_NAME_USE' to 'enum lsa_SidType'
* merge a log more security descriptor functions from
gen_ndr/ndr_security.c in SAMBA_4_0
The most embarassing thing is the "#define strlen_m strlen"
We need a real implementation in SAMBA_3_0 which I'll work on
after this code is in.
