will be owned by the same uid as the containing directory. Doing this for directories
in a race-free mannor has only been tested on Linux (it depends on being able to open
a directory and then do a fchown on that file descriptor). If this functionality is
not available then the code silently downgrades to not changing the ownership of a
new directory. This new parameter (docs to follow) finally makes it possible to create
"drop boxes" on Samba, which requires all files within a directory to be commonly owned.
A HOWTO on how to use this will follow.

that just allow the wrong pointer to be assigned :-) and make the
interface more consistent. Fix the FreeBSD directory problem. Last
thing to do is to add the "singleton" directory concept from James
Peach's code.

evaluation. This stops us from reading the entire directory into
memory at one go, and allows partial reads. It also keeps almost
the same interface to the OpenDir/ReadDir etc. code (sorry James :-).
Next I will optimise the findfirst with exact match code. This speeds
up our interactive response for large directories, but not when a
missing (ie. negative) findfirst is done.

to connection struct entries (as they should have been from
the start). Jerry, once you've cut over to 3.0.4 release
branch I'll add this to 3.0 also.
- Jerry cut over :-).

so breaks when substitution '/' and '\'). It's used by unix_clean_name(),
which is used by reduce_name, which is used by check_name() (phew!).
Now that we know all filenames passed to check_name() are in a "good"
format (no double slashes, all '\\' chars translated to '/' etc.) due
to the new check_path_syntax() we can avoid calling reduce_name unless
widelinks are denied. After this check-in I can fix all_string_sub() to
handle mb chars correctly as it won't be in the direct path in the
main path handling code.

1. Finally work with cascaded modules with private data storage per module
2. Convert VFS API to macro calls to simplify cascading
3. Add quota support to VFS layer (prepare to NT quota support)
Patch by Stefan (metze) Metzemacher, with review of Jelmer and me
Tested in past few weeks. Documentation to new VFS API for third-party developers to follow
then we weren't always correctly detecting that it had a valid stat struct
and so might now return a 'file existed'. Finally realized this when installing
the W2K resource kit as a test case.

- Make ReadDirName return a const char*.
- Consequential changes from that
- mark our fstring/pstring assumptions in function prototypes

a mangled name without a valid stat struct if the file existed. This would
then cause open_file_shared1() to erroneously think the file open was new,
thus not check for oplock break, thus causing a spurious EAGAIN reply to
the open on a file we already had kernel oplocked.... (phew - that was fun
to track down :-).
Jeremy.
Even for a hash/cache setup, this code needs some more work, in particular
it needs to use mangle_get_prefix() etc and to move to unicode internals.
Andrew Bartlett
The problem is that name_map_mangle can *change* the length of a patchname.
Ensure that all the character pointer messing about can cope with changing
sizes of components. This code is too ugly to live.....
This also needs *lots* of testing.
Jeremy.
This commit gets rid of all our old codepage handling and replaces it with
iconv. All internal strings in Samba are now in "unix" charset, which may
be multi-byte. See internals.doc and my posting to samba-technical for
a more complete explanation.
to the cache during the look returned a blank stat struct. Made
weird occurrences such as...
$ smbclient //pogo/print$
smb:\ > cd w32x86
ERROR: Invalid path
smb:\ > cd w32x86
smb:\w32x86\ >
I hope not). If you encounter strange file-serving behavior after this
patch then back it out. I analysed our stat() usage and realised we
were doing approx. 3 stat calls per open, and 2 per getattr/setattr.
This patch should fix all that. It causes the stat struct returned
from unix_convert() (which now *must* be passed a valid SMB_STRUCT_STAT
pointer) to be passed through into the open code. This should prevent
the multiple stats that were being done so as not to violate layer
encapsulation in the API's.
Herb - if you could run a NetBench test with this code and do a
padc/par syscall test and also run with the current 2.2.0 code
and test the padc/par syscalls I'd appreciate it - you should
find the number of stat calls reduced - not sure by how much.
The patch depends on unix_convert() actually finding the file
and returning a stat struct, or returning a zero'd out stat
struct if the file didn't exist. I believe we can guarentee this
to be the case - I just wasn't confident enough to make this
an assertion before.
Ok ok - I did write this whilst at the Miami conference.....
sometimes you get a little free time at these things :-).
Jeremy.
a conn struct depending on the call.
We need this to have a clean NT ACL call interface.
This will break any existing VFS libraries (that's why this is pre-release
code).
Andrew gets credit for this one :-) :-).
In addition - added Herb's WITH_PROFILE changes - Herb - please examine
the changes I've made to the smbd/reply.c code you added. The original
code was very ugly and I have replaced it with a
START_PROFILE(x)/END_PROFILE(x) pair using the preprocessor.
Please check this compiles ok with the --with-profile switch.
Jeremy.
through the VFS. All file access/directory access code in smbd should now
go via the vfs. Added vfs_chown/vfs_chmod calls. Still looking at vfs_get_nt_acl()
vfs_set_nt_acl() call API design.
Jeremy.
call to ms_fnmatch(). This also removes all the Win9X semantics stuff
and a bunch of other associated cruft.
- moved the stat cache code into statcache.c
- fixed the uint16 alignment requirements of ascii_to_unistr() and
unistr_to_ascii()
- trans2 SMB_FIND_FILE_BOTH_DIRECTORY_INFO returns the short name as
unicode always (at least thats what NT4 does)
- fixed some errors in the in-memory tdb code. Still ugly, but doesn't
crash as much
handling to printing/printing.c
most of this was just replacing things like fsp->fd_ptr->fd with fsp->fd
the changes in open.c are quite dramatic. Most of it is removing all
the functions that handled the fd multiplexing
