2000-05-02Moved uglyness needed in fcntl locking (64->32 bit mapping, NFSJeremy Allison1-2/+7
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. (This used to be commit 46092ee1410faa4e3c143d80a960a8adaa19d7fc)
2000-04-22This is a *big* checkin that may break some things, but implements theJeremy Allison1-1/+6
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. (This used to be commit ab0ecc39d688f16b9692fe90b991f0b89287070a)
2000-04-10the bulk of the changes to get rid of fd_ptr and move print openAndrew Tridgell1-4/+3
handling to printing/printing.c most of this was just replacing things like fsp->fd_ptr->fd with fsp->fd the changes in open.c are quite dramatic. Most of it is removing all the functions that handled the fd multiplexing (This used to be commit d1827a3648009fd0a0d165055015d9aeda7a1037)

1999-04-04Wrote VFS initialisation routines.Tim Potter1-0/+407
Converted some useful routines from doscalls.c and changed them to use VFS I/O functions: dos_file_exist dos_read_data dos_write_data dos_transfer_file dos_readdirname Some of these functions have been #ifdef'ed out of doscalls.c as they are not used anywhere else. Not sure whether they should be deleted or not. The remaining dos_* calls seem to be used by clients and for locking stuff. This should be cleaned up sometime.
