The leak checking code which is used by the resolve and failover tests
frees talloc's autofree context which is not recommended. As a
consequence the initialization of tevent failed when it was called by
the second test and CF_FORK=no, because it holds some data in the
autofree context.
This patch introduces a global talloc context which should be uses by
the test as the root of their memory hierarchy instead of NULL. This
global context is used in the leak checking routines.
Not all types of memory leaks can be detected by the new version , it is
recommended to use valgrind or similar tools additionally.

If the monitor receives SIGUSR1, it will instruct all providers to
enter offline operation. If any individual provider receives
SIGUSR1, it alone will enter offline operation.

uint32_t pointers must point to 32 bit aligned data on ARM. Instead of padding the data to force it into alignment I altered the code to memcpy the data to an aligned location. I'd appreciate any and all feedback especially on whether I took the best approach.
pam_test_client auth and pam_test_client acct now work on my armeb-xscale-linux-gnueabi target.

We weren't properly setting read/write flags on the tevent fd
events, so c-ares was unable to perform bidirectional
communication for TCP DNS (in situations where the response is too
large to send by UDP)

This is the preferred way of setting the version in a file, as
autotools will properly monitor this file for changes and rerun
autoconf/configure when necessary to update the version. This
means that we don't need to manually perform an autoreconf in
order to build a new RPM

Right now, the pkg-config checks for the system version of
libdhash are forcibly disabled, requiring the SSSD to build it
from its own tree. In the future, when we split the libraries off
from the SSSD, it will be easy to switch this check to the
external library.

This fixes two issues:
1) Eliminates a double-free when a timeout occurs (we were freeing
the running event context)
2) Ensures that we don't continue to schedule unnecessary timeout
checks

The manual pages for userdel and groupdel utilities incorrectly
stated that deleting a nonexistent user or group is a noop. We
changed that behavior, but forgot to sync the documentation.

The code for authentication against a cached password is moved from the
pam responder to a generic sysdb tevent request. The new code can be
used by other components of sssd to verify passwords on their own.
Tests for the sysdb_cache_password and sysdb_cache_auth request are
added and some unneeded or unused code and variables are removed.

This patch adds a utility called sss_groupshow that allows user to
print properties of a group in the local domain.

Some reformatting to stay within 79 char line length.
Better definition of server vs. machine usage in failover section.

When the resolv context destructor is invoked, the callbacks for pending
queries could have been called with ARES_EDESTRUCTION and try to re-send
the query.

Since ares_process_fd() might also cause fd_event() to be called again,
calling ares_process_fd() is unwise. The bug will cause a crash if
c-ares is using tcp connections.
Fixes: #384
|
|
Since we only call c-ares to process input on FD when there is an
activity on them, c-ares never gets a chance to react to a timed-out
request. This caused SSSD to hang.
Fixes: #381

We will allow 5s per DNS server, no retries.

Tevent frees timer handlers once done, so freeing the timer within the event is
going to cause double frees. Just attach the timer event to the request it
depends on and make sure to steal it on NULL if we are going to free the
request from within the handler.

This was missing from the SSSDConfig API, though it was supported
by the daemon.

The timeout handler was not a child of the request so it could fire even though
the request was already freed.
The code wouldn't use async writes to the children so it could incur in a short
write with no way to detect or recover from it.
Also fixed style of some helper functions to pass explicit paramters instead of
a general structure.
Add common code to do async writes to pipes.
Fixed async write issue for the krb5_child as well.
Fix also sdap_kinit_done(), a return statement was missing and we were mixing
SDAP_AUTH and errno return codes in state->result
Remove usless helper function that just replicates talloc_strndup()

Do not handle a missing ccache file as inactive by default, check if
there are still active processes of the user.

If pam_sm_chauthtok is called with the flag PAM_PRELIM_CHECK set we
generate a separate call to the sssd to validate the old password before
asking for a new password and sending the change password request.

|
|
We support installed access providers as well as permit and deny
|

This matches the DEBUG logging available for groups.

The first fix only fixed tight loops caused by setting 'timeout=0'
in services. This patch also fixes it for domains.
