* actually check for existance of sysctlbyname()

Implements a custom backend for onefs that exclusively uses the wbclient
interface for all passdb calls.
It lacks some features of a standard passdb.
In particular it's a read only interface and doesn't implement privileges.
|
|
This new backend is custom tailored to onefs' unique requirements:
1) No fallback logic
2) Does not validate the domain of the user
3) Handles unencrypted passwords
|
|
Introduce a new configure option --with-wbclient which specifies a
location to find a compatible libwbclient library to link against. This
options is overwritten by --with-winbind

- Attempt to use syscalls to determine max-open-files value.
- Add in periodic logging when max file limit reached

The OneFS Samba implementation of change notify is modeled after the
usage of Linux's inotify kernel subsystem. A single call is made
into the onefs.so VFS module to initialize kernel tracking of certain
file change events. When these events occur a kernel notification is
sent to smbd and the notification event is translated and given to the
general Samba Change Notify layer through a callback function.
The most difficult aspect is converting an SMB CompletionFilter to
a matching ifs_event mask, and then back to an appropriate change
notify action. Currently, not all possible cases are handled by the
this module, but the most prevalent ones, which are tested by
smbtorture, are implemented.

* This allows a problem in the underlying CN backend to be bubbled up
to the general CN layer so a catch-all reply can be returned
* We now also return a catch-all response immediately if the server-side
event queue becomes too big

OneFS notify.
The OneFS kernel based change notify system takes an fd of the directory
to watch in it's initialization syscall. Since we already have this
directory open, this commit plumbs that fd down to the VFS layer via the
notify_entry struct.
We also need to know if the watch is taken out on a snapshot directory.
The full file_id struct is also passed down to make this determination.
The file_id marshalling wrappers are hand written here, but should
eventually be auto-generated by moving the struct file_id into the idl.

As the NFSv4 ACL mapping code doesn't map write directory into the DELETE_CHILD
permission bit (which we require before allowing a delete) no one can delete
files without an explicit DELETE_CHILD bit set on the directory. Add this mapping.

This extends the file_id struct to add an additional generic uint64_t
field: extid. For backwards compatibility with dev/inodes stored in
xattr_tdbs and acl_tdbs, the ext id is ignored for these databases.
This patch should cause no functional change on systems that don't use
SMB_VFS_FILE_ID_CREATE to set the extid.
Existing code that uses the smb_share_mode library will need to be
updated to be compatibile with the new extid.
|
|
Since file_id_create_dev is incompatible with the concept of file_ids,
it is now static and in the one file that needs it.

Martin Zielinski, if you're reading this, please have a look. Vista nicely takes
just a WERR_UNKNOWN_LEVEL here and retries with a level 6 add.

Do not attempt to delete streams on a truncating open, if the name
we're opening is itself a stream.
Port 176e8857203944bc332844b700749120ce90c891 to standard open path

|

Previously, we didn’t call SMB_VFS_OPEN_DIR from the streams module,
instead we called fdopendir(). As a result we failed to populate the
dir_state list in the readdirplus module. So when we tried to view the
stream data, we will always returned NULL.
To solve this I separated onefs_opendir() and the initialization of
the dir_state list. This is done by introducing a new utility function
“onefs_rdp_add_dir_state()”, which initializes the dir_state structure
and adds it to the dir_state list. This function is called from the
streams module before calling readdir().

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.
|
|
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.
