* system: add hole punch support to sys_fallocate()David Disseldorp2015-03-091-2/+9
| | | | | | | | If Samba is configured with FALLOC_FL_PUNCH_HOLE support, then allow sys_fallocate() to propogate the flag to syscall invocation. Signed-off-by: David Disseldorp <ddiss@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
* s3/vfs: change fallocate mode flags from enum->uint32_tDavid Disseldorp2015-03-091-10/+11
| | | | | | | | | | | | | | | | | | | | The Linux fallocate syscall offers a mode parameter which can take the following flags: FALLOC_FL_KEEP_SIZE FALLOC_FL_PUNCH_HOLE (since 2.6.38) FALLOC_FL_COLLAPSE_RANGE (since 3.15) FALLOC_FL_ZERO_RANGE (since 3.14) The flags are not exclusive, e.g. FALLOC_FL_PUNCH_HOLE must be specified alongside FALLOC_FL_KEEP_SIZE. Samba currently takes a vfs_fallocate_mode enum parameter for the VFS fallocate hook, taking either an EXTEND_SIZE or KEEP_SIZE value. This commit changes the fallocate hook such that it accepts a uint32_t flags parameter, in preparation for PUNCH_HOLE and ZERO_RANGE support.

* messaging4: Use messages_dgmVolker Lendecke2015-02-131-1/+1
| | | | | | | | | | | | | This replaces the transport mechanism in source4 with calls to the messages_dgm code. It is supposed to enable "smbcontrol samba pool-usage" as an example without having to rewrite smbcontrol using the source4 based messaging subsystem. This moves the source3 based names.tdb (which is unused so far) to the lock directory, source4 does not have a cache directory.

* lib: Add messages_dgm_ref.[ch]Volker Lendecke2015-02-132-0/+158
| | | | | | | | | | | | | | | We only have one messaging_dgm context per process. But we will use this from two completely independent messaging subsystems which are independently initialized. We need to coordinate creation and destruction, do this via talloc. I know this looks like a step back, but when in the future we have really just one messaging subsystem, this can go again. My immediate goal is to make source3 and source4 transport-compatible, and this looks like a quick way towards that goal.

| | | | | | | | | | | | "pid" and "sock" are sufficient I guess as randomizers to distinguish messages. In theory, a pid could be recycled very quickly, which might mix up in-flight messages.

* messages_dgm: Move directory handling upVolker Lendecke2015-02-133-104/+98
| | | | | | | | | | | | | When we want to use messages_dgm in source4, we need to find better places for the lock and socket directories. Source4 does not have the concept of a cache directory. So I chose "private dir"/sock and "lock dir"/msg as subdirectories. This moves directory creation from messages_dgm.c to messages.c, source4/lib/messaging will have its own way of doing this.

* lib: Add msghdr.[ch]Volker Lendecke2015-01-062-0/+165
| | | | | | | | | | | | | | | | | | | | This is a little set of routines to deal with the ugly fd-passing macros. This patch is the first step assisting the creation of msghrds for sending fds. Receiving fd helpers will follow later. The basic idea behind these routines is that they fill a variable-sized buffer. They are supposed to be called twice per msghdr preparation. First with a 0-sized NULL output buffer to calculate the required bufsize, and then a second time filling in the buffer as such. This does not take care of the old msg_accrights way of passing file descriptors. CMSG/SCM_RIGHTS is standardized for quite a while now, and I believe this intreface can be made to also take care of msg_accrights if needed.
