2009-02-09s3 oplocks: Make the level2 oplock contention API more granularTim Prouty7-27/+62
This replaces release_level2_oplocks_on_change with contend_level2_oplock_begin/end in order to contend level2 oplocks throughout an operation rather than just at the begining. This is necessary for some kernel oplock implementations, and also lays the groundwork for better correctness in Samba's standard level2 oplock handling. The next step for non-kernel oplocks is to add additional state to the share mode lock struct that prevents any new opens from granting oplocks while a contending operation is in progress. All operations that contend level 2 oplocks are now correctly spanned except for aio and synchronous writes. The two write paths both have non-trivial error paths that need extra care to get right. RAW-OPLOCK and the rest of 'make test' are still passing with this change.
2009-02-09s3 oplocks: Differentiate between releasing an oplock vs. downgrading to ↵Tim Prouty3-4/+4
Level 2 for kernel oplocks Pass in an extra argument when releasing an oplock so kernel oplock implementations can support downgrading from Level 1 to Level 2.
2009-02-09s3 vfs: Add a destructor to the fsp extension data APITim Prouty1-1/+7
I'm not certain if the dummy pointer is needed in struct vfs_fsp_data, but I added it to be consistent with the comment below.
2009-02-09S3: New module interface for SMB message statistics gatheringtodd stecher11-35/+278
This changelist allows for the addition of custom performance monitoring modules through smb.conf. Entrypoints in the main message processing code have been added to capture the command, subop, ioctl, identity and message size statistics.

2009-02-01Add two new parameters to control how we verify kerberos tickets. Removes ↵Dan Sledz2-3/+3
lp_use_kerberos_keytab parameter. The first is "kerberos method" and replaces the "use kerberos keytab" with an enum. Valid options are: secrets only - use only the secrets for ticket verification (default) system keytab - use only the system keytab for ticket verification dedicated keytab - use a dedicated keytab for ticket verification. secrets and keytab - use the secrets.tdb first, then the system keytab For existing installs: "use kerberos keytab = yes" corresponds to secrets and keytab "use kerberos keytab = no" corresponds to secrets only The major difference between "system keytab" and "dedicated keytab" is that the latter method relies on kerberos to find the correct keytab entry instead of filtering based on expected principals. The second parameter is "dedicated keytab file", which is the keytab to use when in "dedicated keytab" mode. This keytab is only used in ads_verify_ticket.
2009-02-01Convert api_RNetUserEnum to use the srv_samr_nt.c directlyVolker Lendecke1-26/+77
This is a sample for other accesses to pdb to go via samr. The goal is to access passdb only via srv_samr_nt.c. If that is done, then we can easily swap in another samr implementation like for example samba4's via a unix domain socket.

2009-01-23Extend NTIMES to allow setting create_timetodd stecher4-69/+97
1) Add in smb_file_time struct to clarify code and make room for createtime. 2) Get and set create time from SMB messages. 3) Fixup existing VFS modules + examples Some OS'es allow for the setting of the birthtime through kernel interfaces. This value is generically used for Windows createtime, but is not settable in the code today.

ACLs. If the chown succeeds then the ACL set should also. Ensure this is the case (refactor some of this code to make it simpler to read also). Jeremy.
2009-01-22Another attempt to fix bug #4308 - Excel save operation corrupts file ACLs.Jeremy Allison1-25/+4
Simo is completely correct. We should be doing the chown *first*, and fail the ACL set if this fails. The long standing assumption I made when writing the initial POSIX ACL code was that Windows didn't control who could chown a file in the same was as POSIX. In POSIX only root can do this whereas I wasn't sure who could do this in Windows at the time (I didn't understand the privilege model). So the assumption was that setting the ACL was more important (early tests showed many failed ACL set's due to inability to chown). But now we have privileges in smbd, and we must always fail an ACL set when we can't chown first. The key that Simo noticed is that the CREATOR_OWNER bits in the ACL incoming are relative to the *new* owner, not the old one. This is why the old user owner disappears on ACL set - their access was set via the USER_OBJ in the creator POSIX ACL and when the ownership changes they lose their access. Patch is simple - just ensure we do the chown first before evaluating the incoming ACL re-read the owners. We already have code to do this it just wasn't rigorously being applied. Jeremy.

2009-01-16s3:cluster: fix ctdb ipv6 supportStefan Metzmacher1-3/+1
We need to use CTDB_CONTROL_TCP_CLIENT instead of CTDB_CONTROL_TCP_ADD. CTDB_CONTROL_TCP_CLIENT has support for 2 modes in newer ctdb versions: - with struct ctdb_control_tcp it only supports ipv4. - with struct ctdb_control_tcp_addr it supports ipv4 and ipv6. You need new header files which defines struct ctdb_control_tcp_addr, but at runtime it should be fine to work against older ctdb versions (<= 1.0.68). metze
