struct hbac_eval_req is defined in header file and it has attribute
request_time with type time_t, but header file "time.h" was not included.
It was not problem, because time.h was indirectly included by stdlib.h
(stdlib.h -> sys/types.h -> time.h) in implementation files,
but other platforms can have other dependencies among header files.
|
|
|
|
We use constant AF_INET6 in util.c, but we do not explicitly include header
file sys/socket.h. This header file was indirectly incuded by another header
file netdb.h (netdb.h -> netinet/in.h -> sys/socket.h), but other platform can
have other dependencies among header files.
|
|
Function monitor_config_file_fallback was defined inside of conditional
block "#ifdef HAVE_SYS_INOTIFY_H", but it was also used out of this block.
This patch move declaration of function before start of conditional build
section.
|
|
last argument of function sss_strnlen "size_t *len" is output variable.
We need to increment value of size_t being pointed to by pointer instead of
incrementing pointer.
|
|
Some platform have header file endian.h and anothers have sys/endian.h.
We nedd to use conditional build to handle it correctly, therefore new header
file sss_endian.h was created.

A conflict between two patches was not resolved correctly

Since we now store the enumerate flag in sysdb for subdomains, we can
always descend to all available subdomains and if they do not allow
enumeration, simply skip them.
|
|
https://fedorahosted.org/sssd/ticket/1963
|
|
|
|
The enumerate flag will be read from the cache for subdomains and
the domain object will be created accordingly.
|
|
|
|
Instead of always performing the setup for the main domain, the setup
can now be performed for subdomains as well.
|
|
Instead of always performing the cleanup on the main domain, the task
now accepts a sdap_domain structure to perform the cleanup on. This
change will make the cleanup task reusable for subdomains.
|
|
The LDAP cleanup request was asynchronous for no good reason, probably a
leftover from the days of async sysdb. This patch makes it sychronous
again, removing a lot of uneeded code.

Identity providers other than LDAP need to customize the enumeration in
different ways while sharing the way the task is scheduled etc. The
easiest way to accomplish it is to leverage the recently introduced
ptask framework.
|
|
The LDAP enumeration was too closely tied to the LDAP identity provider.
Because some providers might need special handling such as refresh the
master domain record before proceeding with the enumeration itself, this
patch splits the request itself to a separate async request and lets the
ldap_id_enum.c module only configure this new request.
Also move the enum timestamp to sdap_domain to make the enum tracking
per sdap domain. The cleanup timestamp will be moved in another patch.

|
The constant was not used since Euegene came up with his reconnection
logic.
|
|
The enum code was quite old and predated the tevent_req style. In
particular, the enum code was checking tevent state direcly and not
using _recv functions or the helper macros we added later.
As a consequence, it was not easy to read. This patch adds the standard
_recv functions to read the status of the enum requests.
|
|
The parameter was not used at all.

When IPA trusts an AD domain the AD user or groups can be placed into
IPA groups e.g. to put AD users under the control of HBAC. Since IPA
group can only have members from the IPA directory tree and the AD users
and groups are not stored there a special IPA object called external
group was introduced. SIDs of users and groups can be added to the
external group and since the external groups are in the IPA directory
tree they can be member of IPA groups.
To speed things up and to remove some load from the IPA servers SSSD
reads all external groups and stores them in memory for some time before
rereading the data.

ht_size is size of hash_table in bytes, but hash keys have type uint32_t
|
|
The code uses 2 hashes for each record, but only one hash table to
index them both, furthermore each record has only one single 'next'
pointer.
This means that in certain conditions a record main end up being on a
hash chain even though its hashes do not match the hash chain. This can
happen when another record 'drags' it in from another hash chain where
they both belong.
If the record without matching hashes happens to be the second of the
chain and the first record is removed, then the non matching record is
left on the wrong chain. On removal of the non-matching record the hash
chain will not be updated and the hash chain will end up pointing to an
invalid slot.
This slot may be later reused for another record and may not be the
first slot of this new record. In this case the hash chain will point to
arbitrary data and may cause issues if the slot is interpreted as the
head of a record.
By skipping any block that has no matching hashes upon removing the
first record in a chain we insure that dangling references cannot be
left in the hash table

If len % SSSSRV_PACKET_MEM_SIZE == 0 or some low number,
we can end up with totlen < len and return EINVAL.
It also does not pad the length, but usually allocates
much more memory than is desired.
len = 1024
n = 1024 % 512 + 1 = 0 + 1 = 1
totlen = 1 * 512 = 512
=> totlen < len
len = 511
n = 511 % 512 + 1 = 511 + 1
totlen = 512 * 512 = 262144
totlen is way bigger than it was supposed to be

Currently the AD sites are enabled unconditionally
|

Now that we use the libkrb5 defaults for the default ccname template
we do not need the patch that changes the man pages defaults nor the
configure options to change sssd defaults anymore.
Related:
https://fedorahosted.org/sssd/ticket/2036
|
|
In order to use the same defaults in all system daemons that needs to know how
to generate or search for ccaches we introduce ode here to take advantage of
the new option called default_ccache_name provided by libkrb5.
If set this variable we establish the same default for all programs that surce
it out of krb5.conf therefore providing a consistent experience across the
system.

When we're running 'make rpms' for development purposes, the nested
call to 'make distdir' ends up forcing an update of the translation pot
files. With this patch, we'll automatically ignore them during (S)RPM
actions.

By the time that the create_ccache_in_dir() routine is called, we are
already guaranteed to have dropped privileges. This has either happened
because we dropped them before the exec() in the normal operation case
or because we dropped them explicitly after we completed the TGT
validation step if that or FAST is configured.

If USN attribute is not present, we call strdup on uninitialized
variable. This may cause segfault, or if we are lucky and
usn is NULL it will return ENOMEM.

With the support of POSIX IDs managed on the AD side we may find
non-POSIX groups, i.e. groups which do not have a GID assigned in AD, in
the PAC. Since in this case all cached groups have a SDI attribute it is
more reliable to search the groups by SID instead of GID.
|
|
When processing a list of groups we try to process as much as possible
only not stop on the first error.
|
|
To avoid issues with case-sensitivity it is more reliable to search the
user entry in the cache and use the returned DN instead of constructing
it.
|
|
Since the DN of the group is used to remove a membership it is not
necessary to check if the GID is valid.
|
|
If the user entry does not exist in the cache and a primary GID cannot
be found it does not make sense to create a user entry.
|
|
Currently the PAC responder deletes a user entry and recreates it if
some attributes seems to be different.
Two of the attributes where the home directory and the shell of the
user. Those two attributes are not available from the PAC but where
generates by the PAC responder. The corresponding ID provider might have
better means to determine those attributes, e.g. read them from LDAP, so
we shouldn't change them here.
The third attribute is the user name. Since the PAC responder does
lookups only based on the UID we can wait until the ID provider updates
the entry.

Adds pac_cli be_client structure pointer, to indetify and log the PAC
responder termination correctly.
