2010-02-05s3-smbd: add a rate limited cleanup of brl, connections and locking dbAndrew Tridgell1-6/+42
On unclean shutdown we can end up with stale entries in the brlock, connections and locking db. Previously we would do the cleanup on every unclean exit, but that can cause smbd to be completely unavailable for several minutes when a large number of child smbd processes exit. This adds a rate limited cleanup of the databases, with the default that cleanup happens at most every 20s

2009-08-26s3/smbd: open the share_info.tdb on startup instead of tconxSteven Danneman1-0/+9
This is a small performance optimization. Instead of opening the tdb on every smb connection in the forked child process, we now open it in the parent and share the fd. This also reduces the total fd usage in the system.

Missing become_root()/unbecome_root() around reload_services. Jeremy.
2009-07-15Make gencache more stableVolker Lendecke1-0/+1
This provides a compromise between stability and performance: gencache is a persistent database these days that for performance reasons can not use tdb transactions for all writes. This patch splits up gencache into gencache.tdb and gencache_notrans.tdb. gencache_notrans is used with CLEAR_IF_FIRST, writes to it don't use transactions. By default every 5 minutes and when a program exits, all entries from _notrans.tdb are transferred to gencache.tdb in one transaction.
2009-06-22s3: forward MSG_DEBUG from smbd parent to all childrenAravind Srinivasan1-14/+25
Before 3.3, an smbcontrol debug message sent to the target "smbd" would actually be sent to all running processes including nmbd and winbindd. This behavior was changed in 3.3 so that the "smbd" target would only send a message to the process found in smbd.pid, while the "all" target would send a message to all processes. The ability to set the debug level of all processes within a single daemon, without specifying each pid is quite useful. This was implemented in winbindd in 065760ed. This patch does the same thing for smbd. Upon receiving a MSG_DEBUG the parent smbd will rebroadcast it to all of its children. The printing process has been added to the list of smbd child processes, and we now always track the number of smbd children regardless of the "max smbd processes" setting.

2009-05-27s3: Allow child processes to exit gracefully if we are out of fdsMarc VanHeyningen1-6/+13
When we run out of file descriptors for some reason, every new connection forks a child that immediately panics causing smbd to coredump. This seems unnecessarily harsh; with this code change we now catch that error and merely log a message about it and exit without the core dump. Signed-off-by: Tim Prouty <tprouty@samba.org>

2009-02-18S3: Stop creating SMBD cores when failing to create a pipe.todd stecher1-0/+4
This was uncovered when the MAX FD limit was hit, causing an instant core and invoking error reporting. This fix causes SMBD to exit, but without building a core.
2009-02-18S3: Allow SMBD processes to survive in low memory condidtionstodd stecher1-0/+7
This commit adds a configure argument which allows for setting MADV_PROTECT in the madvise() API. With this enabled the kernel won't kill SMBD when it's running low on memory.

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
2009-01-15s3: make better use of ccache by not including version.h in every C-file.Michael Adam1-1/+1
version.h changes rather frequently. Since it is included via includes.h, this means each C file will be a cache miss. This applies to the following situations: * When building a new package with a new Samba version * building in a git branch after calling mkversion.sh after a new commit (i.e. virtually always) This patch improves the situation in the following way: * remove inlude "version.h" from includes.h * Use samba_version_string() instead of SAMBA_VERSION_STRING in files that use no other macro from version.h instead of SAMBA_VERSION_STRING. * explicitly include "version.h" in those files that use more macros from "version.h" than just SAMBA_VERSION_STRING.

2008-11-06Make us clean under valgrind --leak-check=full by using ↵Jeremy Allison1-3/+3
talloc_autofree_context() instead of NULL. Remove the code in memcache that does a TALLOC_FREE on stored pointers. That's a disaster waiting to happen. If you're storing talloc'ed pointers, you can't know their lifecycle and they should be deleted when their parent context is deleted, so freeing them at some arbitrary point later will be a double-free. Jeremy.
