This change alters the Samba connection code to cache the filesystem
capabilities when a new client connects. This can be used to enable
filesystem specific optimisations is a general manner.
(This used to be commit de3c5b808a)
It hurts, but I think this global variable is necessary for transition, and it
has the potential to remove quite a few other global variables without messing
with APIs too much.
(This used to be commit c131d0dc52)
James, at least on my Linux system neither FILE_CASE_SENSITIVE_SEARCH nor
FILE_CASE_PRESERVING_NAMES seem to be defined anywhere. Is it possible that
this is a MacOS/X specific thing? If so, could you add configure tests for
this?
Thanks,
Volker

This patch adds Darwin support for the Samba statfs VFS call. It
also adds a filesystem capabilities bitmask to the information
returned by the call.
(This used to be commit 555173eb3f)
Up to now, get_nt_acl() took a files_struct pointer (fsp) and
a file name. All the underlying functions should need and now
do need (after the previous preparatory work), is a connection_struct
and a file name. The connection_struct is already there in the
vfs_handle passed to the vfs functions. So the files_struct
argument can be eliminated.
This eliminates the need of calling open_file_stat in a couple
of places to produce the fsp needed.

(This used to be commit b5f600fab5)
Replace smbd/posix_acls.c:get_nt_acl() by two funcions:
posix_get_nt_acl() and posix_fget_nt_acl(). The first
takes a connection struct and a file name instead of a
files_struct pointer. This is in preparation of changing
the vfs api for SMB_VFS_GET_NT_ACL.
Michael
(This used to be commit 50c82cc145)
Convert canonicalise_acl() to take connection_struct, is_directory
and file name instead of files_struct pointer.
Michael
(This used to be commit d579a7f84f)
Convert ensure_canon_entry_valid() to take share_params and an is_directory
flag instead of an files_struct pointer.
Michael
(This used to be commit bdb208124b)
This is a first change in a series: Pass what is needed instead of files_struct
pointers to some functions. This is in preparation of introducing two variants
of get_nt_acl - one for fname (which does not need an fsp), one for file
descriptor.
This changes apply_default_perms to take share_params (rather thatn snum)
and an is_directory flag instead of an fsp.

This is a more general API that caches data with a LRU scheme. See
include/cache.h. No comments yet, I'm still working on it. But Jeremy has given
me a hint in one of his checkins that he would like to make use of this now.
The idea is that we get rid of all our silly little caches and merge them all
into one cache that we can then very easily trim, for example even with a
smbcontrol message if someone decides memory is tight. The main user is the
stat cache, this patch also converts the getwd cache. More caches to come.
(This used to be commit 7a911b3571)
Recent versions of Linux-PAM support localization of user prompts,
so Samba must use the C locale when invoking PAM (directly or via
/usr/bin/passwd) to ensure that password chat values match the prompts in a
locale-invariant fashion.
Jeremy.

If mDNS is supported, attempt to register the first port we are
listening on for the _smb._tcp service. This provides more reliable
service discovery than NetBIOS browsing.
(This used to be commit 1e7241517d)
I'm checking in this long sequence of micro-checkins for review, the overall
patch from 3b057022a5 to this is not too large.

Remove pstring from libsmb/clidfs.c except for a nasty
hack (that will be removed when pstrings are gone from
client/).

Calling can_access_file could lead to orphaned open files
when SMB_VFS_GET_NT_ACL returned ENOSYS (not implemented).

(128k). Add debug error messages so we can see why
writeX large is denied. Ensure we don't allow recvfile
writes on IPC$.
Jeremy.
(This used to be commit 6bf053a6a1)
The three can_* access check functions in smbd/posix_acls.c that are used in
smbd/open.c and smbd/nttrans.c explicitly called check_posix_acl_group_access()
This lead to errors with nfsv4 acls (ZFS and GPFS).
This changes the can_* functions to get the nt_acl via VFS layer and call
se_access_check on that. It also removes check_posix_acl_group_access()
which has no more callers.
NOTE: The can_* functions should really not be in smbd/posix_acls.c but
in a separate file (I propose smbd/access.c).
Michael
(This used to be commit 6f961a23de)
Each cli struct has it's own local copy of this variable,
so use that in client code. In the smbd server, add one
static to smbd/proccess.c and use that inside smbd. Fix
a bunch of places where smb_rw_error could be set by
calling read_data() in places where we weren't reading
from the SMB client socket (ie. winbindd).

up writes by over 10% or so. Complete the server
recvfile implementation.

False instead of NULL. Fix more of the notifications to
be correct for Samba4 RAW-NOTIFY torture (we had missed
one when calling set_ea_dos_attribute().

capability for large UNIX write if not signing and
recvfile set. Cope with large UNIX write length on
incoming processing. Stevef - we can now test 1-16Mb

to zero). If non-zero, writeX calls greater than this
value will be left in the socket buffer for later handling
with recvfile (or userspace equivalent). Definition of
recvfile for your system is left as an exercise for
the reader (I'm working on getting splice working :-).
Jeremy.
(This used to be commit 11c03b75dd)
Right now I'm testing a vfs object. I can't right now in make test, because
"vfs objects" assumes the .so files to be in $libdir/vfs. This patch parses the
module name out of the object name in case it starts with "/". The module name
is assumed to be the last path component's basename.

Hi!
Can you check and push them?

Subject: [PATCH] Fix some warnings and errors
(This used to be commit e17d3e10e8)
to struct sockaddr_storage in most places that matter (ie.
not the nmbd and NetBIOS lookups). This passes make test
on an IPv4 box, but I'll have to do more work/testing on
IPv6 enabled boxes. This should now give us a framework
for testing and finishing the IPv6 migration. It's at
the state where someone with a working IPv6 setup should
(theorecically) be able to type :
smbclient //ipv6-address/share
and have it work.
Jeremy.
(This used to be commit 98e154c312)
Also make use of "if defined(HAVE_IPV6)" rather than testing for
AF_INET6 since this is not sufficient on HP-UX 11.11 to ensure
a working IPv6 implementation.
(This used to be commit 620785df4e)
jra: POPT_ARG_VAL arguments need int values.
I assume there're more places like this
in the cmdline tools.
Please fix this properly, as my commit is just
a hack to get make test working again.
in samba4 we have a workaround for this see
smbd/server.c

BOOL == int). I also need to fix the Samba4 pidl generation
(next checkin).
Jeremy.
(This used to be commit f35a266b3c)
IPv6 in winbindd, but moves most of the socket functions that were
wrongly in lib/util.c into lib/util_sock.c and provides generic
IPv4/6 independent versions of most things. Still lots of work
to do, but now I can see how I'll fix the access check code.
Nasty part that remains is the name resolution code which is
used to returning arrays of in_addr structs.
Jeremy.
(This used to be commit 3f6bd0e1ec)
Why? It moves these structs from the data into the text segment, so they
will never been copy-on-write copied. Not much, but as in German you say
"Kleinvieh macht auch Mist...."

global varables and store address/port in the unexpected db.

We now accept both \\server\tmp and \server\tmp. There are other places

easier now.

the main server code paths. We should now be able to cope with
paths up to PATH_MAX length now.
Final job will be to add the TALLOC_CTX * parameter to
unix_convert to make it explicit (for Volker).
Jeremy.
(This used to be commit 7f0db75fb0)
There are now ony 17 pstrings left in reply.c,
and these will be easy to remove (and I'll be
doing that shortly). Had to fix an interesting
bug in pull_ucs2_base_talloc() when a source
string is not null terminated :-).
Jeremy.
(This used to be commit 0c9a8c4dff)
and make valgrindtest. Final step will be to change srvstr_get_path()
to return talloced memory in the major codepaths.
Jeremy.
(This used to be commit cf6b6f9c3a)
This adds the two functions talloc_stackframe() and talloc_tos().
* When a new talloc stackframe is allocated with talloc_stackframe(), then
* the TALLOC_CTX returned with talloc_tos() is reset to that new
* frame. Whenever that stack frame is TALLOC_FREE()'ed, then the reverse
* happens: The previous talloc_tos() is restored.
*
* This API is designed to be robust in the sense that if someone forgets to
* TALLOC_FREE() a stackframe, then the next outer one correctly cleans up and
* resets the talloc_tos().
The original motivation for this patch was to get rid of the
sid_string_static & friends buffers. Explicitly passing talloc context
everywhere clutters code too much for my taste, so an implicit
talloc_tos() is introduced here. Many of these static buffers are
replaced by a single static pointer.
The intended use would thus be that low-level functions can rather
freely push stuff to talloc_tos, the upper layers clean up by freeing
the stackframe. The more of these stackframes are used and correctly
freed the more exact the memory cleanup happens.
This patch removes the main_loop_talloc_ctx, tmp_talloc_ctx and
lp_talloc_ctx (did I forget any?)
So, never do a
tmp_ctx = talloc_init("foo");
anymore, instead, use
tmp_ctx = talloc_stackframe()

Ronnie. If a lock timeout expires, we must check we can get the
lock before responding with failure. Volker is writing a torture test.

Jeremy, there are two remaining diffs in sesssetup.c which I don't really
know which one is right. Can you take a look?

smbd, nmbd and winbindd can be started with invalid options currently.
The first patch attached would be a possible solution.
It contains an exit if an invalid option has been used. The main problem
is, that existing setups with wrong options or missing arguments in start
scripts will break (which is the right behaviour from my point of view).

vuid that was allocated whilst the connection is
being constructed and after the connection has been set up.
This is what Windows does and at least one client
(and HP printer) depends on this behaviour. As it
depends on the req struct not yet ported to SAMBA_3_2_0
(Volker, hint hint.... :-) I am not yet adding this
to that branch, but will investigate that tomorrow.
Jeremy.
(This used to be commit a54f2805df)
This API will change anyway when moving away from pstrings.
It took so long to fix, because that rename bug I just fixed gave make
test failures that had nothing to do with this one.
I have samba4 tests for both bugs, will check them in when the build
farm has caught up
(This used to be commit d4f442ed9b)
This was broken when I changed reply_mv to wrap in a open_file_ntcreate
call, unix_convert on the destination was called twice
(This used to be commit fddc9db911)
Jeremy, I really apologize for doing this, but I just wanted to enjoy
converting the last SMB call :-)
I've left one little task for you there, I'm not certain that checking
the inbuf length is correct here.
Volker
(This used to be commit 1e08fddafd)
Talked to both Tridge and Jeremy about this, Tridge said that there is a
special error message persuading OS/2 to fall back to other methods.
The calls now checked in always return the error message we used to
return when "read bmpx = False" was set (the default): ERRSRV, ERRuseSTD.
If someone has a reproducable test case where this is really needed, we
can always dig it up from version control and convert it to the new API.
But that time without that silly parameter, and with a torture test case
for "make test" please :-)
