1998-09-05some cleanups to use ZERO_STRUCT() and friendsAndrew Tridgell1-1/+2

1998-09-05tridge the destroyer returns!Andrew Tridgell1-2/+2
prompted by the interpret_security() dead code that Jean-Francois pointed out I added a make target "finddead" that finds potentially dead (ie. unused) code. It spat out 304 function names ... I went through these are deleted many of them, making others static (finddead also reports functions that are used only in the local file). in doing this I have almost certainly deleted some useful code. I may have even prevented compilation with some compile options. I apologise. I decided it was better to get rid of this code now and add back the one or two functions that are needed than to keep all this baggage. So, if I have done a bit too much "destroying" then let me know. Keep the swearing to a minimum :) One bit I didn't do is the ubibt code. Chris, can you look at that? Heaps of unused functions there. Can they be made static? (This used to be commit 2204475c87f3024ea8fd1fbd7385b2def617a46f)

really should be together. Chris -)----- (This used to be commit 8880fc58fa61edfd5a83cc75ef627b430b8a4437)
1998-08-10split the system password checking routines out of smbd/password.c andAndrew Tridgell1-1041/+141
into passdb/pass_check.c. This means SWAT no longer needs to link to smbd/password.c (This used to be commit 90d93889d722670cbb517017531264630af759bf)

Jeremy. (This used to be commit 7d332b2493d2089d09521250fc9b72d8953307c0)
1998-05-12This is a security audit change of the main source.Jeremy Allison1-25/+25
It removed all ocurrences of the following functions : sprintf strcpy strcat The replacements are slprintf, safe_strcpy and safe_strcat. It should not be possible to use code in Samba that uses sprintf, strcpy or strcat, only the safe_equivalents. Once Andrew has fixed the slprintf implementation then this code will be moved back to the 1.9.18 code stream. Jeremy. (This used to be commit 2d774454005f0b54e5684cf618da7060594dfcbb)
1998-05-11ldap back-end database developmentLuke Leighton1-6/+6
Makefile: created PASSBD_OBJ group includes.h: added #ifdef USE_LDAP to #include <ldap> headers ldap.c: - renamed "_machine" to "_trust" everywhere. - added sam_passwd support routines - removed get_ldappwd_entry function: replaced with get_sampwd_entry - removed getldappwnam/uid: replaced with getsampwnam/uid - other messing about bits which are probably going to annoy the hell out of jean-francois (sorry!) mkproto.awk: - added stuff to wrap ldap.c protos with #ifdef USE_LDAP - added uid_t and gid_t return results to the prototype generation passdb.c: - created getsam21pwent, add_sam21pwd_entry, mod_sam21pwd_entry. - modified getsampwnam/uid and created getsam21pwnam/rid functions to replace the local get_smbpwd_entry() and get_ldappwd_entry() functions, which jeremy didn't like anyway because they were dual-purpose. - added utility routines which are or may be useful to all the password database routines. password.c: - renamed "machine_" to "trust_" everywhere. smbpass.c: - removed get_smbpwd_entry function: replaced it with get_sampwd_entry functions in passdb.c - moved code that decoded acct_ctrl into passdb.c - moved encode_acct_ctrl into passdb.c - removed getsmbpwnam/uid: replaced with getsampwnam/uid - renamed "machine_" to "trust_" everywhere. smbpasswd.c: - renamed "machine_" to "trust_" everywhere. util.c: - moved gethexpwd function into passdb.c lib/rpc/server/srv_util.c: - moved user_rid_to_uid, group_rid_to_rid etc etc into passdb.c (This used to be commit 673ab50c4c2c25db355d90efde3a6bfbb4d8369e)
1998-05-11changed to use slprintf() instead of sprintf() just aboutAndrew Tridgell1-7/+7
everywhere. I've implemented slprintf() as a bounds checked sprintf() using mprotect() and a non-writeable page. This should prevent any sprintf based security holes. (This used to be commit ee09e9dadb69aaba5a751dd20ccc6d587d841bd6)
1998-05-10Updated OSF1_ENH_SEC mode password handling.John Terpstra1-1/+8
This now tries Enhanced passwords first and if this fails trys Basic mode (ie: Unix /etc/passwd) authentication. This only happens when OSF1_ENH_SEC is defined at compilation. (This used to be commit 29462c8d7a241eb462b1583170a0b5f16096ea3f)
1998-05-07created "passdb.c" which is an interface point to (at present) eitherLuke Leighton1-6/+6
smbpasswd or ldap passwd, at compile-time (-DUSE_LDAP). _none_ of the functions in ldap.c or smbpass.c should be called directly: only those in passdb.c should be used. -DUSE_LDAP is unlikely to compile at the moment. (This used to be commit 57b01ad4ffb14ebd600d4e66602b54ed987f6106)
1998-05-06smbpass.c: Fixed machine_passwd_lock() problems.Jeremy Allison1-5/+4
password.c: Fixed machine_passwd_lock() problems. lib/rpc/server/srv_ldap_helpers.c: Oops - broke proto.h with dummy function. Fixed now. Jeremy. (This used to be commit d28427f21fff49da6b38c24625e3e2dae49a9713)
1998-05-06Fixes for the %U and %G problems people have reported.Jeremy Allison1-4/+5
Essentially, multiple session_setup_and_X's may be done to an smbd. As there is only one global variable containing the requested connection name (sessionsetup_user), then any subsequent sessionsetups overwrite this name (causing %U and %G to get the wrong name). This is particularly common when an NT client does a null session setup to get a browse list after the user has connected, but before a share has been mounted. These changes store the requested_name in the vuid structure (so this only really works for user level and above security) and copies this name back into the global variable before the standard_sub call. Jeremy. (This used to be commit b5187ad6a3b3af9fbbeee8bced0ab16b41e9825b)
1998-05-05genrand.c: SGI compile warning fix.Jeremy Allison1-14/+15
ipc.c: Fix for duplicate printer names being long. loadparm.c: Set bNetWkstaUserLogon to false by default - new code in password.c protects us. nmbd_logonnames.c: nmbd_namequery.c: nmbd_namerelease.c: Debug messages fix. password.c: SGI compile warning fix, fix for tcon() with bNetWkstaUserLogon call. reply.c: SGI compile warning fix. server.c Debug messages fix. smbpass.c: Fix for incorrect pointer. Jeremy. (This used to be commit 567d3f838988cafab4770fce1cf68b73085e6c71)
1998-04-30Added patch from Bruce Tenison <btenison@dibbs.net> to allow encryptedJeremy Allison1-0/+32
passwords to be stored over time, allowing a smbpasswd file migration. Adds new parameter "update encrypted". Will also add to 1.9.18 branch. Docs update to follow. Jeremy. (This used to be commit 5d3e874d780d595415cc27a7f5945fc2e694c3ac)
1998-04-29clientgen.c: Fixed null session setup bug.Jeremy Allison1-5/+13
password.c: Stopped cli_nt_logout call (we don't have it correct yet). Added Luke object-orientation fix :-). smb.h: Added clnt_name_slash to cli_state. lib/rpc/client/cli_login.c: Changed global_myname to clnt_name_slash where needed. lib/rpc/client/cli_netlogon.c: Fixed debug messages, don't check creds on error. lib/rpc/client/cli_pipe.c: Fixed debug messages, Added Luke object-orientation fix. lib/rpc/parse/parse_misc.c: Fixed STRING2 linearization bug that was adding 1. Jeremy. (This used to be commit c6c22df20196cb7f0ae84b1a1dd202a87adb8d4e)
1998-04-29password.c:Luke Leighton1-0/+4
added become_root / unbecome_root around the get machine account password. smbpass.c: cleaning up code. - turning if (BOOL_expr == False) into if (BOOL_expr) what if you test if (BOOL_expr == True) and someone defines True to be -1 on one system and 1 on another? or if you get inconsistent return results between developers - removed if ((FILE*) == 0) and made this if ((FILE*) == NULL) - cannot assume that NULL is zero integer. plus there are typecast issues to deal with - removed return (ret == 0) ? True : False and made this return ret == 0 rely on the compiler to return correct BOOL value: not all developers will return True or False #defines: stick with BOOL test (non-zero). - removed if (ret == False) replaced with if (!ret) - bug where instead of if (sizeof(pstring)-len-len-6 < 0) it had a boolean test if (pstring-len-len-6). - removed "." after debugging of filenames: the "." - a fullstop - looked like it was part of the filename, making things difficult to sort out. still to be resolved: the global_myname isn't set up, such that the machine account password file is named "TEST3..mac". (This used to be commit 315e26c23abf7137684bf084c825ad241076132e)
1998-04-29This is the checkin that adds the security=domain functionality.Jeremy Allison1-19/+78
WARNING - so far this has only been tested against a Samba PDC (still waiting for IS to add me the machine accounts :-). Still missing is the code in smbpasswd that will add a machine account password and change it on the domain controller, but this is not hard, and I will check it in soon. Jeremy. (This used to be commit 17b94a7084621b3f0106dd4d3386f05cdfc56d19)
1998-04-25This looks like a big change but really isn't.Jeremy Allison1-14/+13
It is changing the global variables "myname" and "myworkgroup" to "global_myname" and "global_myworkgroup" respectively. This is to make it very explicit when we are messing with a global (don't ask - it makes the domain client code much clearer :-). Jeremy. (This used to be commit 866406bfe399cf757c8275093dacd5ce4843afa0)
1998-04-23Makefile: Added nterr.c into the mix.Jeremy Allison1-0/+13

Jeremy. (This used to be commit 899a9f0dce50c73e03c8da2ebe920957491c8ad7)
1998-04-23clientgen.c: Added rap error codes to cli_error, moved from smbpasswd.cJeremy Allison1-54/+161
password.c: Changed global cli -> pw_cli, removed strtok (bad strtok, bad :-) use in security=server, started to extend security=domain code. smbpasswd.c: Removed rap error code functions. Jeremy. (This used to be commit 0f00b8fce1a5cad7f8c212568fa33f09986e5bd6)

All bracketed with #ifdef DOMAIN_CLIENT for now. smbpass.c: New code to get/set machine passwords. Tidied up nesting of lock calls. Jeremy. (This used to be commit 89fe059a6816f32d2cc5c4c04c4089b60590e7e6)

clientgen.c: Changed to fill change password buffer with random stuff. password.c: Changed to get challenge from genrand.c server.c: Added #ifdef around O_SYNC. version.h: Changed to 1.9.19prealpha. genrand.c: New code to generate (hopefully) good random numbers for use in crypto challenges/session keys etc. PLEASE REVIEW THIS CODE AND SUGGEST IMPROVEMENTS !!!!!! Jeremy. (This used to be commit 608e98546392fd0aac9b33f4feac43615dbb4405)
1998-04-14Modified interfaces to getting smb password entries fromJeremy Allison1-2/+2
get_smbpwd_entry (now an internal function to smbpass.c) to a more UNIX-like : getsmbpwnam() - get entry by name. getsmbpwuid() - get entry by uid. Changed the type returned by the smbpasswd enumeration functions to be a void * so that people don't come to depend on it being a FILE *. These abstractions should make it much easier to replace the smbpasswd file with a better backend in future. Other files changed are to match the above changes. Jeremy. (This used to be commit 1161cfb7f2b0d5a6d3e2b524a14a6f325ce70efb)

1998-03-17this isn't a big commit, it just looks like it :-)Andrew Tridgell1-11/+11
I needed the client_name() and client_addr() functions in swat so I could tell who was connecting from where. The problem was that these functions didn't take a file descriptor parameter they just used the global "Client". So I needed to change all calls to pass a parameter ... lots of files. (This used to be commit a776058900a727591bd7b69debdaa25c0e31d693)

1998-03-11"For I have laboured mightily on Luke's code, and hath brokenJeremy Allison1-28/+75
all I saw" - the book of Jeremy, chapter 1 :-). So here is the mega-merge of the NTDOM branch server code. It doesn't include the new client side pieces, we'll look at that later. This should give the same functionality, server wise, as the NTDOM branch does, only merged into the main branch. Any fixes to domain controler functionality should be added to the main branch, not the NTDOM branch. This code compiles without warnings on gcc2.8, but will need further testing before we are sure all the working functionality of the NTDOM server branch has been correctly carried over. I hereby declare the server side of the NTDOM branch dead (and all who sail in her :-). Jeremy. (This used to be commit 118ba4d77a33248e762a2cf843fb7cbc906ee6e7)
