First, this immediately gave me the warning that TDB_ERR_NESTING was not
covered and second, this saved 48 bytes in the .o :-)

This hides the use of talloc_reference from the caller, making it impossible to
wrongly call talloc_free() on the result.
|
|
This removes some dependencies to registry code.

get_current_nttok(conn)
Centralize the root check into smb1_file_se_access_check()
so this is used by modules/vfs_acl_common.c also.

Use accessor functions to get to this value. Tidies up much of
the user context code. Volker, please look at the changes in smbd/uid.c
to familiarize yourself with these changes as I think they make the
logic in there cleaner.
Cause smbd/posix_acls.c code to look at current user context, not
stored context on the conn struct - allows correct use of these
function calls under a become_root()/unbecome_root() pair.

When a samba server process dies hard, it has no chance to clean up its entries
in locking.tdb, brlock.tdb, connections.tdb and sessionid.tdb.
For locking.tdb and brlock.tdb Samba is robust by checking every time we read
an entry from the database if the corresponding process still exists. If it
does not exist anymore, the entry is deleted. This is not 100% failsafe though:
On systems with a limited PID space there is a non-zero chance that between the
smbd's death and the fresh access, the PID is recycled by another long-running
process. This renders all files that had been locked by the killed smbd
potentially unusable until the new process also dies.
This patch is supposed to fix the problem the following way: Every process ID
in every database is augmented by a random 64-bit number that is stored in a
serverid.tdb. Whenever we need to check if a process still exists we know its
PID and the 64-bit number. We look up the PID in serverid.tdb and compare the
64-bit number. If it's the same, the process still is a valid smbd holding the
lock. If it is different, a new smbd has taken over.
I believe this is safe against an smbd that has died hard and the PID has been
taken over by a non-samba process. This process would not have registered
itself with a fresh 64-bit number in serverid.tdb, so the old one still exists
in serverid.tdb. We protect against this case by the parent smbd taking care of
deregistering PIDs from serverid.tdb and the fact that serverid.tdb is
CLEAR_IF_FIRST.
CLEAR_IF_FIRST does not work in a cluster, so the automatic cleanup does not
work when all smbds are restarted. For this, "net serverid wipe" has to be run
before smbd starts up. As a convenience, "net serverid wipedbs" also cleans up
sessionid.tdb and connections.tdb.
While there, this also cleans up overloading connections.tdb with all the
process entries just for messaging_send_all().

this module adds optional server-side support for limited rename operations
beyond filesystem boundaries, which was the previously the default.
|
|
cross-device rename support has some major limitations:
- on huge files clients will timeout or hang
- ACLs and EA information is not retained
Usually a client will have to handle this. A Windows Server with a reparse
point will also just return NT_STATUS_NOT_SAME_DEVICE. We will now by default
do the same.
I will add a vfs module which will restore the old cross-device renames.

Now that cifs-utils are their own project, we need to go ahead and pull
them out of the samba tree. This patch represents the first step toward
that end.
Remove the cifs-utilities from the source3 and source4 builds. Please
pay particular attention to the source4 piece. I'm not at all familiar
with the build system there, and would appreciate someone sanity
checking my changes.
It also adds a small README.cifs-utils file in the topdir. This is
optional, but I think it's a good idea to carry this for a release or
two.
Once this patch looks ok, I'll plan to do another patch to actually
remove the client dir and the relevant docs-xml files from the tree
altogether.

Ensure we don't use any of the create_options for Samba private
use. Add a new parameter to the VFS_CREATE call (private_flags)
which is only used internally. Renumber NTCREATEX_OPTIONS_PRIVATE_DENY_DOS
and NTCREATEX_OPTIONS_PRIVATE_DENY_FCB to match the S4 code).
Rev. the VFS interface to version 28.
