* totally rewrote the async signal, notification and oplock notificationAndrew Tridgell2000-06-122-109/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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!

* Linux kernel oplocks now seem to work, but need a _lot_ of testingAndrew Tridgell2000-06-113-11/+21
| | | | | I had to modify sys_select() to not loop on EINTR. I added a wrapper called sys_select_intr() which gives the old behaviour.
* continued the split of the kernel level oplocks code into a moreAndrew Tridgell2000-06-101-0/+2
| | | | | modular form. In this pass I added oplock_irix.c and added a "struct kernel_oplocks" that describes a kernel oplock implementation.

* Fixed LsaQueryInformationPolicy level 3 to return primary domain info.Matthew Chapman2000-05-291-9/+12
| | | | | | | Domain SID is saved in secrets.tdb upon joining domain. Added "Authenticated Users" and "SYSTEM" well-known SIDs (under NT Authority).

* - changed smb_getpwnam() to use winbind style usernamesAndrew Tridgell2000-05-101-7/+6
| | | | - finished ntdom -> winbind rename in head
* more merging voodooAndrew Tridgell2000-05-101-0/+4
| | | | | | 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

| | | | Jeremy.
* a minimal change to get appliance mode to work with winbinddAndrew Tridgell2000-05-041-0/+35
| | | | | | | | | we needed to accept usernames of the form DOMAIN/user, which means we needed to pass the domain to a getpwnam() like routine in certain critical spots. What I'd rather do is get rid of "char *user" everywhere and use the new userdom_struct, but that will have to wait a few days.
* split the username in the vuser structure into a separateAndrew Tridgell2000-05-021-2/+2
| | | | | | | | 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.
* Moved uglyness needed in fcntl locking (64->32 bit mapping, NFSJeremy Allison2000-05-021-102/+6
| | | | | | | errors etc.) into locking/posix.c, where it is needed. fcntl_lock in lib/util.c is now very small and clean. Added (*lock) op to vfs layer. Jeremy.
* Added sys_fork() and sys_getpid() functions to stop the overheadJeremy Allison2000-05-029-10/+42
| | | | | of doing a system call every time we want to just get our pid. Jeremy.
* - added some error checkingAndrew Tridgell2000-04-301-1/+1

* - removed all our old wildcard matching code and replaced it with aAndrew Tridgell2000-04-302-627/+69
| | | | | | | | | | | | | | | | call to ms_fnmatch(). This also removes all the Win9X semantics stuff and a bunch of other associated cruft. - moved the stat cache code into statcache.c - fixed the uint16 alignment requirements of ascii_to_unistr() and unistr_to_ascii() - trans2 SMB_FIND_FILE_BOTH_DIRECTORY_INFO returns the short name as unicode always (at least thats what NT4 does) - fixed some errors in the in-memory tdb code. Still ugly, but doesn't crash as much
* YIPEE!!!!!Andrew Tridgell2000-04-302-1/+147
| | | | | | | | | | | We finally have a perfect emulation of Microsoft wildcard matching. The routine ms_fnmatch() does wildcard matching with all MS wildcards (including the unicode wildcards), and masktest against a NT4 workstation with hundreds of thousands of random exmaples has not found a single error. amazingly it is only about 60 lines of code, but it has taken us years to get it right. I didn't sleep much last night :)

| | | | | | | | | | | | fsp->open is no longer needed (if an fsp pointer is valid, then it's open :-). NB for Luke, this patch also did not apply to TNG. TNG is not yet identical w.r.t file serving with HEAD. This makes it impossible for me to help maintain TNG. Please fix asap. lib/substitute.c: Removed unused variable (pidstr). Jeremy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | new open mechanism Andrew & I discussed. config.sub: configure: Included the QNX patch. include/vfs.h: smbd/vfs-wrap.c: smbd/vfs.c: Added ftruncate vfs call (needed). Note that we will also need locking calls in the vfs (to be added). lib/util_unistr.c: nmbd/nmbd_processlogon.c: Fix for NT domain logons causing nmbd to core dump. Also fix for sidsize DOS bug. locking/locking.c: Check value of ret before using it for memdup. printing/printing.c: Convert print_fsp_open to return an allocated fsp. rpc_server/srv_lsa.c: Fix for NT domain logons. I have removed all use of lp_share_modes() from the code (although I left the parameter in the table for backwards compatibility). It no longer makes sense for this to exist. smbd/close.c: Removed lp_share_modes(). smbd/fileio.c: Fixed parameters to unlock_share_entry call in panic code. smbd/files.c: Correctly set the unix_ERR_code to ERRnofids on fsp allocation fail. smbd/nttrans.c: smbd/reply.c: smbd/trans2.c: Changed all occurrences of open_file_shared/open_directory/ open_file_stat to return an fsp from the call. smbd/open.c: Changed all occurrences of open_file_shared/open_directory/ open_file_stat to return an fsp from the call. In addition I have fixed a long standing race condition in the deny mode processing w.r.t. two smbd's creating a file. Andrew, please note that your original idea of using open with O_EXCL in this case would not work (I went over the races very carefully) and so we must re-check deny modes *after* the open() call returns. This is because there is a race between the open with O_EXCL and the lock of the share mode entry. Imagine the case where the first smbd does the open with O_EXCL and a deny mode of DENY_ALL, but is pre-empted before it locks the share modes and creates the deny mode entry for DENY_ALL. A second smbd could then come in with O_RDONLY and a deny mode of DENY_NONE and the two opens would be allowed. The *only* way to fix this race is to lock the share modes after the open and then do the deny mode checks *after* this lock in the case where the file did not originally exist. This code will need extensive testing but seems to initially work. Jeremy.
