2000-08-02Started to canonicalize our handling of uid -> sid code in order toJeremy Allison1-2/+1
get ready and fix se_access_check(). Added cannonical lookup_name(), lookup_sid(), uid_to_sid(), gid_to_sid() functions that look via winbind first the fall back on local lookup. All Samba should use these rather than trying to call winbindd code directly. Added NT_USER_TOKEN struct in user_struct, contains list of NT sids associated with this user. se_access_check() should use this (cached) value rather than attempting to do the same thing itself when given a uid/gid pair. More work needs to be done to preserve these things accross security context changes (especially with the tricky pipe problem) but I'm beginning to see how this will be done..... probably by registering a new vuid for an authenticated RPC pipe and not treating the pipe calls specially. More thoughts needed - but we're almost there... Jeremy. (This used to be commit 5e5cc6efe2e4687be59085f562caea1e2e05d0a8)
2000-07-27Ok - this is a *BIG* change - but it fixes the problems with static stringsJeremy Allison1-0/+1
in the RPC code. This change was prompted by trying to save a long (>256) character comment in the printer properties page. The new system associates a TALLOC_CTX with the pipe struct, and frees the pool on return of a complete PDU. A global TALLOC_CTX is used for the odd buffer allocated in the BUFFERxx code, and is freed in the main loop. This code works with insure, and seems to be free of memory leaks and crashes (so far) but there are probably the occasional problem with code that uses UNISTRxx structs on the stack and expects them to contain storage without doing a init_unistrXX(). This means that rpcclient will probably be horribly broken. A TALLOC_CTX also needed associating with the struct cli_state also, to make the prs_xx code there work. The main interface change is the addition of a TALLOC_CTX to the prs_init calls - used for dynamic allocation in the prs_XXX calls. Now this is in place it should make dynamic allocation of all RPC memory on unmarshall *much* easier to fix. Jeremy. (This used to be commit 0ff2ce543ee54f7364e6d839db6d06e7ef1edcf4)
2000-06-14allow the notify implementation to choose the select timeout changeAndrew Tridgell1-11/+11
(This used to be commit b1441d9622609af5ef598c5e1e1f5af438dc0731)
2000-06-12totally rewrote the async signal, notification and oplock notificationAndrew Tridgell1-133/+120
handling in Samba. This was needed due to several limitations and races in the previous code - as a side effect the new code is much cleaner :) in summary: - changed sys_select() to avoid a signal/select race condition. It is a rare race but once we have signals doing notification and oplocks it is important. - changed our main processing loop to take advantage of the new sys_select semantics - split the notify code into implementaion dependent and general parts. Added the following structure that defines an implementation: struct cnotify_fns { void * (*register_notify)(connection_struct *conn, char *path, uint32 flags); BOOL (*check_notify)(connection_struct *conn, uint16 vuid, char *path, uint32 flags, void *data, time_t t); void (*remove_notify)(void *data); }; then I wrote two implementations, one using hash/poll (like our old code) and the other using the new Linux kernel change notify. It should be easy to add other change notify implementations by creating a sructure of the above type. - fixed a bug in change notify where we were returning the wrong error code. - rewrote the core change notify code to be much simpler - moved to real-time signals for leases and change notify Amazingly, it all seems to work. I was very surprised! (This used to be commit 44766c39e0027c762bee8b33b12c621c109a3267)
2000-06-11Linux kernel oplocks now seem to work, but need a _lot_ of testingAndrew Tridgell1-51/+56
I had to modify sys_select() to not loop on EINTR. I added a wrapper called sys_select_intr() which gives the old behaviour. (This used to be commit b28cc4163bc2faaa80c5782fc02c8f03c410cdeb)

2000-05-10more merging voodooAndrew Tridgell1-0/+3
this adds "#define OLD_NTDOMAIN 1" in lots of places. Don't panic - this isn't permanent, it should go after another few merge steps have been done (This used to be commit 92109d7b3c06f240452d39f669ecb8c9c86ab610)

2000-05-02split the username in the vuser structure into a separateAndrew Tridgell1-1/+1
userdom_struct. As the name implies this also contains a domain (unused at the moment). This will be important shortly, as operation in appliance mode needs the domain to be always carried with the username. (This used to be commit ee8546342d5be90e730372b985710d764564b124)
2000-05-02Added sys_fork() and sys_getpid() functions to stop the overheadJeremy Allison1-1/+1
of doing a system call every time we want to just get our pid. Jeremy. (This used to be commit 148628b616b5c29ba6340d65fc3ddbcabba6e67a)
2000-04-30 - added some error checkingAndrew Tridgell1-8/+0
- removed the VTP hook in smbd (This used to be commit 09355fcd50e6c9c0c81e5f70ab9b7ff88aa897bf)
2000-04-27Ok - this is more subtle than it looks :-).Jeremy Allison1-1/+1
When a file is being closed, once it passes the fnum and tid tests then the locking context should be ignored when removing all locks. This is what is done in the brl close case, but when you have outstanding POSIX locks, then you cannot remove all the brl locks in one go, you have to get the lock list and call do_unlock individually. As this uses global_smbpid as the locking context, you need to make sure that this is set correctly for the specific lock being removed. I now do this by storing the smbpid in each entry in the unlock list returned from the query call. I removed the smbpid from fsp (not needed) and things seem ok (even with the stupid smbpid tricks that smbtorture plays :-). Jeremy. (This used to be commit 6baa96bb466915cc17e8cbad50254d6bd47b967b)
2000-04-27Fixed subtle unlocking bug when a file is closed. We need to store theJeremy Allison1-1/+1
smbpid used when a file was opened in the files_struct. Else we use the wrong global_smbpid when we are closing the file and trying to remove the brl locks - this causes the brl locks to be left when the file is closed as the samba_context check fails. Jeremy. (This used to be commit 2746e5602e493e5b022764b4b839eb4d2f14363b)
2000-04-15Log file check patch from Mattias Gronlund <Mattias.Gronlund@sa.erisoft.se>.Jeremy Allison1-0/+6
Modified to do checks in timeout processing not in main loop. This (IMHO) is the correct place as (a) we are already root, and (b) it is guarenteed to be called every 200 smb requests. Jeremy. (This used to be commit c3794fd29fdc4e5a0dbd725cdc24fe210934caf2)
2000-04-11finally got sick of the "extern int Client" code and the stupidAndrew Tridgell1-15/+11
assumption that we have one socket everywhere while doing so I discovered a few bugs! 1) the clientgen session retarget code if used from smbd or nmbd would cause a crash as it called close_sockets() which closed our main socket! fixed by removing close_sockets() completely - it is unnecessary 2) the caching in client_addr() and client_name() was bogus - it could easily get fooled and give the wrong result. fixed. 3) the retarget could could recurse, allowing an easy denial of service attack on nmbd. fixed. (This used to be commit 5937ab14d222696e40a3fc6f0e6a536f2d7305d3)

2000-01-14some more work on the byte range lockingAndrew Tridgell1-2/+7
note the ugly global_smbpid - I hope that won't bethere for long, I just didn't want to do two lots of major surgery at the one time. Using global_smbpid avoids the big change of getting rid of our inbuf/outbuf interface to reply routines. I'll do that once the locking stuff passes all tests.

2000-01-05implemented talloc() as described on samba-technical. This fixes theAndrew Tridgell1-0/+3
lp_string() bug properly. we still need to add lp_talloc_free() calls in all the main event loops, I've only put it in smbd and nmbd thus far. (This used to be commit aa7f81552540f5dca2c146f5edd805611d5b390f)

1999-11-15- added DCE/RPC "fault" PDU support.Luke Leighton1-1/+1
- disabled (AGAIN) the GETDC "if (MAILSLOT\NTLOGON)" code that will get NT5rc2 to work but WILL break win95 (AGAIN). this needs _not_ to be re-enabled but to be replaced with a better mechanism. - added SMBwrite support (note: SMBwriteX already existed) as NT5rc2 is sending DCE/RPC over SMBwrite not SMBwriteX.

1999-04-01Ken McDonell from SGI was interested in adding some profilingAndrew Tridgell1-0/+4
capabilities to Samba so that Samba could talk to the SGI PCP (Performance Co-Pilot) apps. This change adds a profiling shared memory area and uses it to count two fairly trivial things, the number of uid switches and the number of SMB packets processes. To add more just edit include/profile.h and then increment it at the right place. I've also added a -P switch to smbstatus to dump the profile area. (This used to be commit ef3d61a80ad0b87c196a63ef2bd4fe8fc3863bd0)

1998-09-05tridge the destroyer returns!Andrew Tridgell1-157/+129
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)

the head of an SMB request (ie. are part of a chain) will not be queued - this will be fixed when we move to the new chain code. In practice, this doesn't seem to cause much of a problem (in my admittedly limited testing) bug a debug level zero message will be placed in the log when this happens to help determine how real the problem is. smbd/locking.c: New debug messages. smbd/blocking.c: New blocking code - handles SMBlock, SMBlockread and SMBlockingX smbd/chgpasswd.c: Fix for master fd leak. smbd/files.c: Tidyup comment. smbd/nttrans.c: Added fnum to debug message. smbd/process.c: Made chain_reply() use construct_reply_common(). Added blocking lock queue processing into idle loop. smbd/reply.c: Added queue pushes for SMBlock, SMBlockread and SMBlockingX. Jeremy.

1998-08-17this completes the splitup of server.c.Andrew Tridgell1-0/+810
the splitup was done with an axe, not a scalpel, so there are some rough edges. I mostly wanted to get the general form right with fine tuning of what goes where to come later. Still, this is better than what we had before where server.c was a general repository for anything that didn't fit elsewhere. (This used to be commit a6d194886a4a5f7507fa37289ff96c1be56f14a6)
