Fix bug #6717.
|
|
===========================================================
== Subject: Misconfigured /etc/passwd file may share folders unexpectedly
==
== CVE ID#: CVE-2009-2813
==
== Versions: All versions of Samba later than 3.0.11
==
== Summary: If a user in /etc/passwd is misconfigured to have
== an empty home directory then connecting to the home
== share of this user will use the root of the filesystem
== as the home directory.
===========================================================

FreeBSD (and other BSDs, too) need sys/sysctl.h inclueded to use sysctlbyname().
Thanks to Timur Bakeyev for that.

This is necessary because MIT 1.5 can't deal with certain types (Tree Root) of
transitive AD trusts. The workaround is to add a [capaths] directive to
/etc/krb5.conf, which we don't automatically put into the krb5.conf winbind
creates.
The alternative would have been something like a "krb5 conf include", but I
think if someone has to mess with /etc/krb5.conf at this level, it should be
easy to add the site-local KDCs as well.
Next alternative is to correctly figure out the [capaths] parameter for all
trusted domains, but for that I don't have the time right now. Sorry :-)

that stores the create time in the user.DosTimestamps EA.

s3: Make smbd aware of permission change of usershare. Since usershare are relatively volatile and
non-previledge users must disconnect from smbd and reconnect to it to make share permission in effect.
For now. This is a feature request and I think we need
to design it a little differently so as not to touch
core change_to_user() code.

Use common paths like for smbpasswd, so that all utilities
behave the same way. As for smbpasswd this changes the behavior
of pdbedit to create/delete unix users is the add/delete user
scripts are provided, or ldapsam:editposix is configured.

This patch introduces
struct stat_ex {
dev_t st_ex_dev;
ino_t st_ex_ino;
mode_t st_ex_mode;
nlink_t st_ex_nlink;
uid_t st_ex_uid;
gid_t st_ex_gid;
dev_t st_ex_rdev;
off_t st_ex_size;
struct timespec st_ex_atime;
struct timespec st_ex_mtime;
struct timespec st_ex_ctime;
struct timespec st_ex_btime; /* birthtime */
blksize_t st_ex_blksize;
blkcnt_t st_ex_blocks;
};
typedef struct stat_ex SMB_STRUCT_STAT;
It is really large because due to the friendly libc headers playing macro
tricks with fields like st_ino, so I renamed them to st_ex_xxx.
Why this change? To support birthtime, we already have quite a few #ifdef's at
places where it does not really belong. With a stat struct that we control, we
can consolidate the nanosecond timestamps and the birthtime deep in the VFS
stat calls.
At this moment it is triggered by a request to support the birthtime field for
GPFS. GPFS does not extend the system level struct stat, but instead has a
separate call that gets us the additional information beyond posix. Without
being able to do that within the VFS stat calls, that support would have to be
scattered around the main smbd code.
It will very likely break all the onefs modules, but I think the changes will
be reasonably easy to do.

This fixes bug #4271: testparm should not print includes.

This should reduce the waste of memory when using "config file"
or "config backend". It also reduces the risk of triggering
reloads due to some old unused files being checked.

instead of reading the registry directly with tdb and activating the
configure options by hand.
This eliminates the need for repeating checks done in loadparm.
For instance it disables registry shares without path in the server
as is the case with text based shares.

This introduces a hard coded MAX_INCLUDE_DEPTH of 100.
When this is exceeded, handle_include (and hence lp_load) fails.
One could of course implement a more intelligent loop detection
in the include-tree, but this would require some restructuring
of the internal loadparm housekeeping. Maybe as a second improvement
step.

We keep the seqnum/mid mapping in the smb_request structure.
This also moves one global variable into the
smbd_server_connection struct.

After the discussion on samba-technical, it was decided that the best
answer for now was to revert this change. The right way to do this is
to rewrite the token api to use opaque tokens with pluggable modules.
This reverts commit 8e19a288052bca5efdb0277a40c1e0fdd099cc2b.

- Attempt to use syscalls to determine max-open-files value.
- Add in periodic logging when max file limit reached
|
|
When set to yes, "force username map" forces every user, even AD
users, through an NSS lookup. This allows the token to be overridden
with information from NSS in certain broken environments.

parameter name

When enabled this reverts smbd to the legacy domain remapping behavior when
a user provides an untrusted domain
This partially reverts d8c54fdd
|
|
This changelist allows for the addition of custom performance
monitoring modules through smb.conf. Entrypoints in the main message
processing code have been added to capture the command, subop, ioctl,
identity and message size statistics.

lp_use_kerberos_keytab parameter.
The first is "kerberos method" and replaces the "use kerberos keytab"
with an enum. Valid options are:
secrets only - use only the secrets for ticket verification (default)
system keytab - use only the system keytab for ticket verification
dedicated keytab - use a dedicated keytab for ticket verification.
secrets and keytab - use the secrets.tdb first, then the system keytab
For existing installs:
"use kerberos keytab = yes" corresponds to secrets and keytab
"use kerberos keytab = no" corresponds to secrets only
The major difference between "system keytab" and "dedicated keytab" is
that the latter method relies on kerberos to find the correct keytab
entry instead of filtering based on expected principals.
The second parameter is "dedicated keytab file", which is the keytab
to use when in "dedicated keytab" mode. This keytab is only used in
ads_verify_ticket.

version.h changes rather frequently. Since it is included via includes.h,
this means each C file will be a cache miss. This applies to the following
situations:
* When building a new package with a new Samba version
* building in a git branch after calling mkversion.sh
after a new commit (i.e. virtually always)
This patch improves the situation in the following way:
* remove inlude "version.h" from includes.h
* Use samba_version_string() instead of SAMBA_VERSION_STRING
in files that use no other macro from version.h instead of
SAMBA_VERSION_STRING.
* explicitly include "version.h" in those files that use more
macros from "version.h" than just SAMBA_VERSION_STRING.

LDAP_SSL_ON is not defined at all. That's why the actual default value
was "" for a long time. Set a more sensible default value without chnging the
default behaviour.

It's the same in 3.2 and 3.3 series.
