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.

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.
A socket where the other side has closed only becomes readable. To catch
errors early when sitting in a pure writev, we need to also test for
readability.
Jeremy as far as I can see there is no real technical reason to limit the
number of interfaces. If you like this patch, can you please merge it to 3.4?
If you don't please tell me :-)
Thanks,

This patch picks the alphabetically smallest one of the multi-value attribute
"uid". This fixes a regression against 3.0 and also becomes deterministic.
Haven't checked this myself, but as I've already got several reports that Samba
won't compile against current OpenAFS anymore, I just believe Geza Gemes. This
patch only affects AFS code, so it should not hurt anything else.

Included if pthreads are found, can be disabled with --enable-pthreadpool=no
Tim, Steven, I haven't yet seen comments from you. You have been asking for
such a thing at SambaXP. Do you like this? :-)
The merged version behaves differently: "Domain Users" is parsed into two
values, as it does not look at quotes. Samba3 users depend on the ability do
say for example
valid users = "domain users"
which would not work anymore with the merged version.
Thanks to Björn Jacke for testing this!

* ldb_dn_new() now takes an initial DN string
* ldb_dn_string_compose() -> ldb_dn_new_fmt()
* dummy ldb_dn_validate(), since LDB DNs in the current implementation
are always valid if they could be created.
This argument is ignored (Samba3's LDB is synchronous) but having it
there is useful for API compatibility with the LDB used by Samba 4 and
available on some systems.
What a difference a name makes... :-). Just because something is missnamed
SAMR_ACCESS_OPEN_DOMAIN, when it should actually be SAMR_ACCESS_LOOKUP_DOMAIN,
don't automatically use it for a security check in _samr_OpenDomain().
Jeremy.
This removes calls to push_*_allocate() and pull_*_allocate(), as well
as convert_string_allocate, as they are not in the common API
To allow transition to a common charcnv in future, provide Samba4-like
strupper functions in source3/lib/charcnv.c
(the actual implementation remains distinct, but the API is now shared)
Andrew Bartlett
This renames push_string in Samba3 into push_string_base and
push_string_check for the two different use cases.
This should allow push_string to be imported from Samba4, using it's
calling conventions.
Clustered setups should have only ever used
the unsigned version of TDB_DATA in the
first place so they can't be in this mess :-).
Just do the normal upgrade in the clustered case.
Jeremy.
