This has been a wrapper around server_event_context() for some time
now, and removing this from dummmysmbd.c assists with library
dependencies.

oplocks.
This one is subtle. There is a race condition where a signal can be
queued for oplock break, and then the file can be closed by the client
before the signal can be processed. Currently if this occurs we panic
(we can't match an incoming signal fd with a fsp pointer). Simply log
the error (at debug level 10 right now, might be too much) and then
return without processing the break request. It looks like there is
another race condition with this fix, but here's why it won't happen.
If the signal was pending (caused by a kernel oplock break from a
local file open), and the client closed the file and then re-opened
another file which happened to use the same file descriptor as the
file just closed, then theoretically the oplock break requests could
be processed on the wrong fd. Here's why this should be very rare..
Processing a pending signal always take precedence over an incoming
network request, so as long as the client close request is non-chained
then the break signal should always be harmlessly processed *before*
the open can be called. If the open is chained onto the close, and
the fd on the new open is the same as the old closed fd, then it's
possible this race will occur. However, all that will happen is that
we'll lose the oplock on this file. A shame, but not a fatal event.

Should help track if we get invoked with an invalid fd from
the signal handler.

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.

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.
|
|
And use signal events for Linux oplocks.

This converts the irix oplocks code to use a fd event
and removes the last special case for file descriptors
for the main sys_select().

The goal is to move all this variables into a big context structure.

Can someone with gpfs available test this ? The only codepath using this
function is the modules/gpfs.c module. The fix resolves at least the build
issues Samba has with recent kernel / libcap versions by using the portable
cap_get_proc()/cap_set_proc() interface (instead of using capget/capset).

bugs in various places whilst doing this (places that assumed

This replaces the internal explicit dev/ino file id representation by a
"struct file_id". This is necessary as cluster file systems and NFS
don't necessarily assign the same device number to the shared file
system. With this structure in place we can now easily add different
schemes to map a file to a unique 64-bit device node.
Jeremy, you might note that I did not change the external interface of
smb_share_modes.c.

it should be abstracted a little higher up so other os'es can have an
entry, but it will take a bit more work. Thanks to Chetan Shringarpure
and Mathias Dietz.
I didn't increment the vfs number again because the kernel change notify
stuff hasn't been released yet anyway.

fsp pointers. Ensure we cope with this to pass Samba4
DENY tests (we used to pass these, there must have been
a regression with newer code). We now pass them.

modes and
oplocks across the cluster. Adapt Samba to it.
The gpfs API is called via libgpfs.so. This code is written with dlopen(), so
that you can compile on a system with gpfs installed and later on run on
systems without gpfs available.
So to actually make Samba call gpfs share mode calls you need to compile with
gpfs.h and libgpfs.so around and set 'gpfs share = yes' on the shares you
export from GPFS.

tests on this as it's very late NY time (just wanted to get this work
into the tree). I'll test this over the weekend....
Jerry - in looking at the difference between the two trees there
seem to be some printing/ntprinting.c and registry changes we might
want to examine to try keep in sync.

1. using smbc_getxattr() et al, one may now request all access control
entities in the ACL without getting all other NT attributes.
2. added the ability to exclude specified attributes from the result set
provided by smbc_getxattr() et al, when requesting all attributes,
all NT attributes, or all DOS attributes.
3. eliminated all compiler warnings, including when --enable-developer
compiler flags are in use. removed -Wcast-qual flag from list, as that
is specifically to force warnings in the case of casting away qualifiers.
Note: In the process of eliminating compiler warnings, a few nasties were
discovered. In the file libads/sasl.c, PRIVATE kerberos interfaces
are being used; and in libsmb/clikrb5.c, both PRIAVE and DEPRECATED
kerberos interfaces are being used. Someone who knows kerberos
should look at these and determine if there is an alternate method
of accomplishing the task.
