1d710d06a2 r13915: Fixed a very interesting class of realloc() bugs found by Coverity.
realloc can return NULL in one of two cases - (1) the realloc failed,
(2) realloc succeeded but the new size requested was zero, in which
case this is identical to a free() call.

The error paths dealing with these two cases should be different,
but mostly weren't. Secondly the standard idiom for dealing with
realloc when you know the new size is non-zero is the following :

 tmp = realloc(p, size);
 if (!tmp) {
    SAFE_FREE(p);
    return error;
 } else {
    p = tmp;
 }

However, there were *many* *many* places in Samba where we were
using the old (broken) idiom of :

 p = realloc(p, size)
 if (!p) {
    return error;
 }

which will leak the memory pointed to by p on realloc fail.

This commit (hopefully) fixes all these cases by moving to
a standard idiom of :

 p = SMB_REALLOC(p, size)
 if (!p) {
    return error;
 }

Where if the realloc returns null due to the realloc failing
or size == 0 we *guarentee* that the storage pointed to by p
has been freed. This allows me to remove a lot of code that
was dealing with the standard (more verbose) method that required
a tmp pointer. This is almost always what you want. When a
realloc fails you never usually want the old memory, you
want to free it and get into your error processing asap.

For the 11 remaining cases where we really do need to keep the
old pointer I have invented the new macro SMB_REALLOC_KEEP_OLD_ON_ERROR,
which can be used as follows :

 tmp = SMB_REALLOC_KEEP_OLD_ON_ERROR(p, size);
 if (!tmp) {
    SAFE_FREE(p);
    return error;
 } else {
    p = tmp;
 }

SMB_REALLOC_KEEP_OLD_ON_ERROR guarentees never to free the
pointer p, even on size == 0 or realloc fail. All this is
done by a hidden extra argument to Realloc(), BOOL free_old_on_error
which is set appropriately by the SMB_REALLOC and SMB_REALLOC_KEEP_OLD_ON_ERROR
macros (and their array counterparts).

It remains to be seen what this will do to our Coverity bug count :-).

Jeremy.

123e478ce5 r13815: "Into the blind world let us now descend,"
Began the poet, his face as pale as death.
"I will go first, and you will follow me."
---

Adding XcvDataPort() to the spoolss code for remotely
add ports.  The design is to allow an intuitive means
of creating a new CUPS print queue from the Windows 2000/XP
APW without hacks like specifying the deviceURI in the
location field of the printer properties dialog.

Also set 'default devmode = yes' as the new default
since it causes no harm and only is executed when you
have a NULL devmode anyways.

lp_load() could not be called multiple times to modify parameter settings based
 on reading from multiple configuration settings.  Each time, it initialized all
 of the settings back to their defaults before reading the specified
 configuration file.

 This patch adds a parameter to lp_load() specifying whether the settings should
 be initialized.  It does, however, still force the settings to be initialized
 the first time, even if the request was to not initialize them.  (Not doing so
 could wreak havoc due to uninitialized values.)

2253b17a1a r12721: GPFS 2.4 on Linux will contain some windows semantics, ie share modes and
oplocks across the cluster. Adapt Samba to it.

The gpfs API is called via libgpfs.so. This code is written with dlopen(), so
that you can compile on a system with gpfs installed and later on run on
systems without gpfs available.

So to actually make Samba call gpfs share mode calls you need to compile with
gpfs.h and libgpfs.so around and set 'gpfs share = yes' on the shares you
export from GPFS.

5629ca1623 r11909: Implement 'reset on zero vc'. This kills other connections when a session
setup comes in with the vc (virtual connection) field set to zero. This is
done by Windows, probably you can tweak that by some registry key.

	This boolean option controls whether an incoming session setup
	should kill other connections coming from the same IP. This matches
        the default Windows 2003 behaviour.

	Setting this parameter to yes becomes necessary when you have a flaky
	network and windows decides to reconnect while the old connection
	still has files with share modes open. These files become inaccessible
	over the new connection.

	The client sends a zero VC on the new connection, and Windows 2003
	kills all other connections coming from the same IP. This way the
	locked files are accessible again.

	Please be aware that enabling this option will kill connections behind
	a masquerading router.

e0bf0581f0 r11295: new service hashing code has assumign that the service
name stored in the array was normalized.  This was causing

Seems to be ok after this change.

Also converted canonicalize_servicename() to just
use strupper_m() rather than doing the conversion itself.
Jeremy, i think this should be ok but please check.

also cleaned up some things in the hash service code

d07343e0c4 r11266: Speed up loading smb.conf for large numbers of share definitions. The problem
was a O(n^2) loop: Whenever a service definition was found, we linearly
searched the already loaded share definitions, the patch adds an internal tdb
for this. For a smb.conf with 2000 shares this speeds up loading by about a
factor of 50.

Might be a fix for bug #1117.

49ef8b88a3 r11190: Fix enhancement request #3192.
This does 2 things.
1). Makes dfree command a per-share parameter (it should be anyway IMHO).
2). Adds a "dfree cache time" parameter in seconds that specifies how long a
dfree command output should be cached for. Default is zero (no caching).

91596330ea r8145: When inventing a new parameter for SFU-support, be aware of Volker's

Therefor (after speaking with Volker) replace "winbind sfu support" with

SFU-support set it to "winbind nss info = template sfu".

28b5969942 r7994: This adds support in Winbindd's "security = ads"-mode to retrieve the POSIX
homedirectory and the loginshell from Active Directory's "Services for Unix".

Enable it with:

        winbind sfu support = yes

User-Accounts without SFU-Unix-Attributes will be assigned template-based
Shells and Homedirs as before.

Note that it doesn't matter which version of Services for Unix you use (2.0,
2.2, 3.0 or 3.5). Samba should detect the correct attributes (msSFULoginShell,
msSFU30LoginShell, etc.) automatically.

If you also want to share the same uid/gid-space as SFU then also use PADL's
ad-idmap-Plugin:

        idmap backend = ad

When using the idmap-plugin only those accounts will appear in Name Service
Switch that have those UNIX-attributes which avoids potential uid/gid-space
clashes between SFU-ids and automatically assigned idmap-ids.
