Hack that should get the buildfarm back to green.
Ensure dirfd() needs to be defined before we properly return fdopendir.
This will do until we get a proper dirfd() defined in libreplace.
From http://www.gnu.org/software/hello/manual/gnulib/dirfd.html
This function is missing on some platforms: AIX 7.1, HP-UX 11, OSF/1 5.1, Solaris 10, mingw.

this is just relevant for the very rare systems that don't have the st_blocks
struct member. This is a fixup of the fix for bug 7474.
Thanks to Joachim Schmitz for spotting this!

This reverts commit a6ae7a552f851a399991262377cc0e062e40ac20.
This fixes bug #7222 (All users have full rigths on all shares) (CVE-2010-0728).

Only works on Linux kernels 2.6.26 and above. Grants CAP_KILL capability
to allow Linux threads under different euids to send signals to each other.

this is in preparation for other preallocation methods to be introduced.

posix_fallocate is more efficient than manual zero'ing the file. When
preallocation in kernel space is supported it's extremely fast. Support for
preallocation at fs layer via posix_fallocate and fallocate at kernel site
can be found in Linux kernel 2.6.23/glibc 2.10 with ext4, XFS and OCFS2. Other
systems that I know of which support fast preallocation in kernel space are
AIX 6.1 with JFS2 and recent Solaris versions with ZFS maybe UFS2, too.
People who have a system with preallocation in kernel space might want to set
"strict allocate = yes". This reduces file fragentation and it's also safer for
setups with quota being turned on.
As of today most systems still don't have preallocation in kernel space, and
that's why "strict allocate = no" will stay the default for now.

in the "user.DOSATTRIB" EA. From the docs:
In Samba 3.5.0 and above the "user.DOSATTRIB" extended attribute has been extended to store
the create time for a file as well as the DOS attributes. This is done in a backwards compatible
way so files created by Samba 3.5.0 and above can still have the DOS attribute read from this
extended attribute by earlier versions of Samba, but they will not be able to read the create
time stored there. Storing the create time separately from the normal filesystem meta-data
allows Samba to faithfully reproduce NTFS semantics on top of a POSIX filesystem.
Passes make test but will need more testing.

create time from the existing timestamps (for systems
that need to do this). Once the write time is changed
via a sticky write, the create time might need to be
recalculated. To do this I needed to add a bool into
struct stat_ex to remember if the st_ex_btime field
was calculated, or read from the OS. Also fixed the
returning of modified write timestamps in the return
from NTCreateX, SMBattr and SMBattrE (which weren't
taking into account the modified timestamp stored
in the open file table). Attempting to fix an issue
with Excel 2003 and offline files. Volker and Metze,
please review.

This patch introduces
struct stat_ex {
dev_t st_ex_dev;
ino_t st_ex_ino;
mode_t st_ex_mode;
nlink_t st_ex_nlink;
uid_t st_ex_uid;
gid_t st_ex_gid;
dev_t st_ex_rdev;
off_t st_ex_size;
struct timespec st_ex_atime;
struct timespec st_ex_mtime;
struct timespec st_ex_ctime;
struct timespec st_ex_btime; /* birthtime */
blksize_t st_ex_blksize;
blkcnt_t st_ex_blocks;
};
typedef struct stat_ex SMB_STRUCT_STAT;
It is really large because due to the friendly libc headers playing macro
tricks with fields like st_ino, so I renamed them to st_ex_xxx.
Why this change? To support birthtime, we already have quite a few #ifdef's at
places where it does not really belong. With a stat struct that we control, we
can consolidate the nanosecond timestamps and the birthtime deep in the VFS
stat calls.
At this moment it is triggered by a request to support the birthtime field for
GPFS. GPFS does not extend the system level struct stat, but instead has a
separate call that gets us the additional information beyond posix. Without
being able to do that within the VFS stat calls, that support would have to be
scattered around the main smbd code.
It will very likely break all the onefs modules, but I think the changes will
be reasonably easy to do.

This fixes a bug in 116ce19b, where we didn't clear the pid cache in
become_daemon() and thus the /var/run/smbd.pid didn't match the actual
pid of the parent process.
Currently S4 will clear the pid cache on fork but doesn't yet take
advantage of the pid cache by using sys_pid() instead of the direct
get_pid().

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).

Some systems (eg Mac OSX 10.5) require the length passed to match
the socket address family. This introduces sys_connect() that does
the right thing, and replaces all uses oc connect(2) with sys_connect().
Note that there are some LGPL callers that still call connect(2)
directly.
