2011-02-02Based on a conversation with Volker, refactor some of the oplock code to ↵Jeremy Allison1-71/+160
make it comprehensible. delay_for_oplocks() did 4 things. 1). Validation of existing oplock types. 2). Check for compatibility with batch oplocks (pass 1). 3). Check for compatibility with exclusive oplocks (pass 2). 4). Set the correct oplock type from the requested value. Refactor into 4 separate functions: 1). find_oplock_types() - does validation of oplock types and returns pointers to specific values. 2). delay_for_batch_oplocks() - the pass 1 phase above. 3). delay_for_exclusive_oplocks() - the pass 2 phase above 4). grant_fsp_oplock_type() - Set the correct oplock type from the requested value. Now separated out this code should be much easier to understand and modify. This also fixes an erroneous SMB_ASSERT which was hidden by the previous complexity of the single delay_for_oplocks() code.

2011-01-31Fix bug #7928 - Samba problems with kernel oplocks option set to "no"Pavel Shilovsky1-1/+4
We should not grant levelII oplocks on a file with existing byte range locks.
2011-01-25Fix bug #7863 - Unlink may unlink wrong file when hardlinks are involved.Jeremy Allison1-4/+8
Do this by keeping a linked list of delete on close tokens, one for each filename that identifies a path to the dev/inode. Use the jenkins hash of the pathname to identify the correct token.
2010-12-29Fix bug #7892 - open_file_fchmod() leaves a stale lock.Jeremy Allison1-36/+4

2010-10-22Revert "Wrap security_token_has_privilege() with a check for ↵Jeremy Allison1-2/+2
lp_enable_privileges(). Needed" Not needed - privileges code prevents "enable privileges = no" from adding privileges anyway. This reverts commit a8b95686a7bde3f96f141b6938e24e101567ef54. Autobuild-User: Jeremy Allison <jra@samba.org> Autobuild-Date: Fri Oct 22 23:41:36 UTC 2010 on sn-devel-104

2010-10-15Fix bug #7734 - When creating files with "inherit ACLs" set to true, we ↵Jeremy Allison1-1/+1
neglect to apply appropriate create masks. Jeremy.
2010-10-15Fix bug #7733 - Invalid client DOS attributes on create can cause incorrect ↵Jeremy Allison1-0/+9
unix mode_t to be generated. It turns out a client can send an NTCreateX call for a new file, but specify FILE_ATTRIBUTE_DIRECTORY in the attribute list. Windows silently strips this, but we don't - causing the unix_mode() function to go through the "mode bits for new directory" codepath, instead of the "mode bits for new file" codepath. Jeremy.
2010-10-12libcli/security Provide a common, top level libcli/security/security.hAndrew Bartlett1-0/+1
This will reduce the noise from merges of the rest of the libcli/security code, without this commit changing what code is actually used. This includes (along with other security headers) dom_sid.h and security_token.h Andrew Bartlett Autobuild-User: Andrew Bartlett <abartlet@samba.org> Autobuild-Date: Tue Oct 12 05:54:10 UTC 2010 on sn-devel-104

2010-09-11s3:auth Remove NT_USER_TOKENAndrew Bartlett1-1/+1
The all UPPER case typedef is no longer the preferred Samba style and this makes it easier to see that this is the IDL-derivied structure Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>

2010-07-29s3: Avoid an unnecessary ftruncate callVolker Lendecke1-1/+1
If we just created the file, it has length 0 by definition. This is still done while holding the share mode lock, so no race around wrt other cifs clients.

2010-05-13Treat an open of stream ::$DATA as an open of the base file.Jeremy Allison1-1/+23
This fixes a class of SMB_ASSERT failures when doing stream tests. Jeremy.

2010-04-23Allow smb2 create requests to be cancelled.Jeremy Allison1-9/+18
Jeremy.
2010-04-22Make deferred opens (NT_STATUS_SHARING_VIOLATION) work over SMB2.Jeremy Allison1-1/+1
Makes SMB2Create call re-entrant internally. Now this infrastructure is in place, oplocks will follow shortly. Tested with Win7 client and with W2K8R2. Jeremy.
2010-04-12Move to using 64-bit mid values in our internal open file database.Jeremy Allison1-6/+8
This will allow us to share logic much easier between SMB1 and SMB2 servers. Jeremy
2010-04-09Plumb SMB2 stubs into all the places we defer SMB1 operations.Jeremy Allison1-26/+26
Rename functions to be internally consistent. Next step is to cope queueing single (non-compounded) SMB2 requests to put some code inside the stubs. Jeremy.
2010-03-15Switch over to using get_currect_XXX() accessor functions.Jeremy Allison1-3/+3
Jeremy.
2010-03-15Rever e80ceb1d7355c8c46a2ed90d5721cf367640f4e8 "Remove more uses of "extern ↵Jeremy Allison1-3/+3
struct current_user current_user;"." As requested by Volker, split this into smaller commits. Jeremy.
2010-03-12Missed a couple more uses of conn->server_info->ptok that need to be ↵Jeremy Allison1-19/+22
get_current_nttok(conn) Centralize the root check into smb1_file_se_access_check() so this is used by modules/vfs_acl_common.c also. Jeremy.
2010-03-12Remove more uses of "extern struct current_user current_user;".Jeremy Allison1-3/+3
Use accessor functions to get to this value. Tidies up much of the user context code. Volker, please look at the changes in smbd/uid.c to familiarize yourself with these changes as I think they make the logic in there cleaner. Cause smbd/posix_acls.c code to look at current user context, not stored context on the conn struct - allows correct use of these function calls under a become_root()/unbecome_root() pair. Jeremy.
2010-03-05Fix for bug #7189 - Open txt files with notepad on samba shares creates problem.Jeremy Allison1-19/+36
Ensure we don't use any of the create_options for Samba private use. Add a new parameter to the VFS_CREATE call (private_flags) which is only used internally. Renumber NTCREATEX_OPTIONS_PRIVATE_DENY_DOS and NTCREATEX_OPTIONS_PRIVATE_DENY_FCB to match the S4 code). Rev. the VFS interface to version 28. Jeremy.
2009-12-16Add helpful debug of DACL for errors on ACL access.Jeremy Allison1-2/+10

fsp->fsp_name. Moving towards making VFS_OPEN/VFS_MKDIR/VFS_RMDIR handle based... Jeremy.
2009-12-02Remove unneeded argument from can_set_delete_on_close(). EnsureJeremy Allison1-2/+2
can_set_delete_on_close() is correctly called before any setting of the disposition bit (clean up the do_unlink() call). Jeremy.
