LDAP/UDP messages. Slapd marks received CLDAP messages as LDAP_VERSION2.
The client library can generate CLDAP queries if -Protocol 2 is chosen,
otherwise not. LDAPv2 CLDAP cannot query the slapd rootDSE, gets no reply.
Compile with -DLDAP_CONNECTIONLESS to use this code.
For slapd, use "-h cldap://" to listen on UDP.
For ldapsearch, use "-H cldap://" to query on UDP.
Client-side support is very minimal:
no automatic timeout/retries
no basedn wildcard expansion on results
no support for specifying multiple servers at once.
r/w locks and thread pools. Hide internal structures (using
pthread'ish technics). Place common code in threads.c. Move
no-thread code to thr_stub.c. Move thread pool code to tpool.c.
Removed setconcurrency call from initializer, added 'concurrency'
directive to slapd. Tested code under pthreads, pth, and no-threads.
SASL mech removed from backend bind callback (as SASL is managed by frontend)
Changes to some backends are untested (as I don't have all dependent
software install)
This means a ldaps connection may drop before any LDAP protocol exchange
occurs (due to expired cert, unrecognized CAs, etc.).
Change ldap_pvt_tls_connect to copy any TLS error string to ld_error upon
connection failure, otherwise client just sees "can't contact LDAP server."
slapd/connection.c: add flush/delay when SSL_accept fails, to allow any
TLS alerts we generated to propagate back to the client. (Which will then
be picked up by ldap_pvt_tls_connect on the client...)
Only return SLAPD_DISCONNECT with a send_ldap_disconnect()
was called.
Add initial code for support predetermined filter results
when filter is undefined (or known to be true or false).
support for DCE slash-delimited, left-to-right DNs;
support for a domain socket transport (enable with
--enable-ldapi); and extensions to URL parsing to
support the latter transport.
result was leaking ber's in some error cases. ber_flush now called
with no freeing so that caller of send_ldap_ber() can free its own ber.
c->c_currentber was also being leaked if connection was destory
current when a PDU input was outstanding.
Fixed ber_flush to free ber upon write only to file.
by <who> <access> changed to by <who>+ <access> (joined with AND)
added peername=<regex> sockname=<regex> url=<regex>
removed addr=<regex> (use peername instead).
replace dn_upcase with str2upper and str2lower. Use where needed.
added slap_ and ldbm_ to many structures
added typedefs to many structures
used typedefs
New main.c argument parsing with ldap url support (replacing -a address).
New sockaddr_in handling and support for multiple listeners.
connection_init so that we get into the select() logic.
Make use of new flags in the connection.
BTW, and before I forget, it sort of works. I have connected with
a Netscape client using a secure connection and did a failed
search (my test database is empty), but the trace looked correct.
Make sure you have your CA certificate in your Netscape preinstalled.
Otherwise, the connection fails with error 0xFFFFFFFF that is rather
uninformative.
Added configuration support for "digest-realm <realm>" configure directive.
Added connection state and bind_in_progress fields to cn=monitor connection
attribute.
added lber_types.h.nt, lber_types.h.in
removal of NULLxxx internal macros (in favor of NULL).
ch_free added to slapd,slurpd/ch_malloc.c
#define free ch_free (should be removed after s/free/ch_free/g) in proto-slap.h
ch_malloc and friends use ber_memalloc and friends
added comments
removed LDAP_MAX_ATTR_LEN
removed LDAP_COMPAT* from <ldap.h> but not code.
move LDAP_DEFAULT_REFHOPCOUNT to ldap-int.h
added experimental options macros
added LDAP_CONTROL_REFERRALS macros
libldap:
Replace ld_attrbuffer with per use allocated attributed.
ldap_first/next_attribute attributes now must be freed (as per draft).
unifdef -DLDAP_API_FEATURE_X_OPENLDAP_V2_REFERRALS
This commit includes many changes. All changes compile under NT but
have not been tested under UNIX.
A Summary of changes (likely incomplete):
NT changes:
Removed lint.
Clean up configuration support for "Debug", "Release", "SDebug",
and "SRelease" configurations.
Share output directories for clients, libraries,
and slapd. (maybe they should be combined further
and moved to build/{,S}{Debug,Release}).
Enable threading when _MT is defined.
Enable debuging when _DEBUG is defined.
Disable setting of NDEBUG under Release/SRelease. Asserts
are disabled in <ac/assert.h> when LDAP_DEBUG is not
defined.
Added 'build/main.dsp' Master project.
Removed non-slapd projects from slapd.dsp (see main.dsp).
Removed replaced many uses of _WIN32 macro with feature based
macros.
ldap_cdefs.h changes
#define LDAP_CONST const
(see below)
#define LDAP_F(type) LDAP_F_PRE type LDAP_F_POST
To allow specifiers to be added before and after
the type declaration. (For DLL handling)
LBER/LDAP changes
Namespace changes:
s/lber_/ber_/ for here and there.
s/NAME_ERROR/LDAP_NAME_ERROR/g
Deleted NULLMSG and other NULL* macros for namespace reasons.
"const" libraries. Installed headers (ie: lber.h, ldap.h)
use LDAP_CONST macro. Normally set to 'const' when
__STDC__. Can be set externally to enable/disable
'constification' of external interface. Internal
interface always uses 'const'. Did not fix warnings
in -lldif (in lieu of new LDIF parser).
Added _ext API implementations (excepting search and bind).
Need to implement ldap_int_get_controls() for reponses
with controls.
Added numberous assert() checks.
LDAP_R
_MT defines HAVE_NT_THREADS
Added numberous assert() checks.
Changed ldap_pthread_t back to unsigned long. Used cast
to HANDLE in _join().
LDBM
Replaced _WIN32 with HAVE_SYSLOG
ud
Added version string if MKVERSION is not defined. (MKVERSION
needs to be set under UNIX).
slapd
Made connection sockbuf field a pointer to a sockbuf. This
removed slap.h dependency on lber-int.h. lber-int.h now only
included by those files needing to mess with the sockbuf.
Used ber_* functions/macros to access sockbuf internals whenever
possible.
Added version string if MKVERSION is not defined. (MKVERSION
needs to be set under UNIX).
Removed FD_SET unsigned lint
slapd/tools
Used EXEEXT to added ".exe" to routines. Need to define EXEEXT
under UNIX.
ldappasswd
Added ldappasswd.dsp. Ported to NT. Used getpid() to seed rand().
nt_debug
Minor cleanup. Added "portable.h" include and used <ac/*.h> where
appropriate. Added const to char* format argument.
prior to connection management changes). No "normal" (wait
for pending operations to complete) shutdown mode (yet).
Changes:
Add connections_destroy() implementation to connections.c.
Move connections_init() call to slap_daemon().
Add connections_destroy() call to slap_daemon().
Add connections_shutdown() implementation to connections.c.
calls connection_closing()/connection_close() for each
"in use" connection.
Add connections_shutdown() call to slap_daemon_task().
remove race conditions on connection close.
BROKEN: various counters for dn=monitor.
Initial testing on FreeBSD (with and without pthreads) was successfull.
Have not yet tested preemptive threading environments.
Have not built against backends other than LDBM.
SLAP_C_ACTIVE vs SLAP_C_INACTIVE. Need to implement BINDING and CLOSING.
Added fields tracking pending (on bind) ops. Could also be used to
implement per-connection thread limits.
Likely broke things for non-posix threadings....
Update -lldap_r implementation to:
remove attribute support
hide thread detachment
provide concurrency accessors
provide initialization function
fix gethostby{addr,name}_r codes (not coverred by HAVE_REENTRANT_FUNCTIONS)
Update servers/libraries to use ldap_pvt_thread_ calls.
Cleanup server codes (no #ifdef HAVE_PTHREAD_THIS or _THATs)!
Removed -llthread
creating them detached. This hopefully will reduce problems on
draft4 pthread implementations related to creating detached
threads (which is _np under draft4) on some platforms without
causing problems with other thread implementations.
of a busy wait and allow the pthread_yield within the loop to be
removed. This was the only pthread_yield which was necessary
when usng non-preemptive threads. As such, the configure.in
sched_yield/pthread_yield missing error can be removed from
configure.in. If explicit yield function is missing, just provide
a no-op replacement.
Moved declaration of various slapd globals from main.c to init.c
so they can be shared with ldbm tools.
rename 'struct conn' to 'struct slap_conn'
rename op_function to slap_op_func for functions add/delete/free
This change is need to avoid clashing with perl internals.
Most function and variable definitions are now preceded by its extern
definition, for error checking. Retyped a number of functions, usually
to return void. Fixed a number of printf format errors.
API changes (in ldap/include):
Added avl_dup_ok, avl_prefixapply, removed ber_fatten (probably typo
for ber_flatten), retyped ldap_sort_strcasecmp, grew lutil.h.
A number of `extern' declarations are left (some added by protoize), to
be cleaned away later. Mostly strdup(), strcasecmp(), mktemp(), optind,
optarg, errno.
-thread & -pthread are still treated as libraries, will need
additional work to use them as CFLAGS.
Eliminated HAVE_DCE define (was redundant) and its use. Code
now relies on draft4 and function existance tests.
