2010-08-14tdb: workaround starvation problem in locking entire database.Rusty Russell4-19/+131
We saw tdb_lockall() take 71 seconds under heavy load; this is because Linux (at least) doesn't prevent new small locks being obtained while we're waiting for a big log. The workaround is to do divide and conquer using non-blocking chainlocks: if we get down to a single chain we block. Using a simple test program where children did "hold lock for 100ms, sleep for 1 second" the time to do tdb_lockall() dropped signifiantly. There are ln(hashsize) locks taken in the contended case, but that's slow anyway. More analysis is given in my blog at http://rusty.ozlabs.org/?p=120 This may also help transactions, though in that case it's the initial read lock which uses this gradual locking routine; the update-to-write-lock code is separate and still tries to update in one go. Even though ABI doesn't change, minor version bumped so behavior change can be easily detected. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2010-08-13s3-smbd: Publish nt printers.Andreas Schneider2-5/+15
Reloading of the printers requires rpc services up and running! The first call in reload_services will be skipped. Signed-off-by: Simo Sorce <idra@samba.org>
2010-08-13s3-smbd: Move rpc services init to smbd parent.Andreas Schneider2-42/+46
The move to the parent makes it possible to use an internal rpc pipe really early and as we migrated serveral parts of samba to rpc function this is required. This should speed up the fork of a smbd a bit cause the rpc services are already running. We still have several problems here which aren't solved. We don't have a dependency tree here. For example we have to make sure that the registry is initialized before we can use the winreg pipe. The spoolss server requires winreg, so we have to start winreg before we can start the spoolss server. I'm sure there are more dependencies. Signed-off-by: Simo Sorce <idra@samba.org>

2010-08-13s3-krb5 Only build ADS support if arcfour-hmac-md5 is availableAndrew Bartlett10-21/+2520
Modern Kerberos implementations have either defines or enums for these key types, which makes doing #ifdef difficult. This shows up in files such as libnet_samsync_keytab.c, the bulk of which is not compiled on current Fedora 12, for example. The downside is that this makes Samba unconditionally depend on the arcfour-hmac-md5 encryption type at build time. We will no longer support libraries that only support the DES based encryption types. However, the single-DES types that are supported in common with AD are already painfully weak - so much so that they are disabled by default in modern Kerberos libraries. If not found, ADS support will not be compiled in. This means that our 'net ads join' will no longer set the ACB_USE_DES_KEY_ONLY flag, and we will always try to use arcfour-hmac-md5. A future improvement would be to remove the use of the DES encryption types totally, but this would require that any ACB_USE_DES_KEY_ONLY flag be removed from existing joins.

performance counter code. In the file rpc_server.c, function _winreg_QueryValue() uint8_t *outbuf Should be : uint8_t *outbuf = NULL; As it is later freed by if (free_buf) SAFE_FREE(outbuf); in some cases, this frees the unintialized outbuf, which causes a coredump.

2010-08-12s3: Reduce the load on the echo handlerVolker Lendecke1-0/+2
If the parent is fast enough, the echo handler should not step in. When the socket becomes readable, the echo handler goes to sleep for a second. If within that second, the parent has picked up the SMB request from the net, the echo handler will just go back to select().
