Use the RAP_NetServerEnum3 server list continuation API for retrieving
server lists that are too long to fit in a single reply.
Patch from George Colley <gcolley@apple.com>.
process deep dfs links (ie. links that go to non root
parts of a share). Make the directory handling conanonical
in POSIX and Windows pathname processing.
dfs should not be fully working in client tools. Please
bug me if not.

workgroup, decided periodically to stop sending recognized responses to a
NetServerEnum2 request for the workgroup. Instead of returning the list of
servers (only itself; nothing else in the workgroup), it returns a status code
of 8 which is unsupported by samba3, samba4, and ethereal.
The code for this request assumed that if an unexpected status code was
received, the connection had a problem, i.e. that cli_errno() would show a
problem. That turns out not to be the case.
This patch changes the behavior so tha any time a response is received and
cli_errno() == 0, we continue processing the reply and base our response on
the returned count (zero). The pre-existing code then converts this count=0
into an ENOENT errno which can be properly handled by the application (whereas
an error return with errno=0 can't be).
This packet dump has only 2 frames. Sorry about the text version but it's
most easily attached to this log message. I also have it saved as .pcap if
anyone wants it.

This completes the work Jeremy began last week, disambiguating the meaning of
c_time. (In POSIX terminology, c_time means "status Change time", not "create
time".) All uses of c_time, a_time and m_time have now been replaced with
change_time, access_time, and write_time, and when creation time is intended,
create_time is used.
Additionally, the capability of setting and retrieving the create time have
been added to the smbc_setxattr() and smbc_getxattr() functions. An example
of setting all four times can be seen with the program
examples/libsmbclient/testacl
with the following command line similar to:
testacl -f -S "system.*:CREATE_TIME:1000000000,ACCESS_TIME:1000000060,WRITE_TIME:1000000120,CHANGE_TIME:1000000180" 'smb://server/share/testfile.txt'
The -f option turns on the new mode which uses full time names in the
attribute specification (e.g. ACCESS_TIME vs A_TIME).
on the wire. This allows us to go to nsec resolution
for systems that support it. It should also now be
easy to add a correct "create time" (birth time)
for systems that support it (*BSD). I'll be watching
the build farm closely after this one for breakage :-).
Jeremy.
Fix cli_setpathinfo() to actually do what it's supposed to.
Also, get rid of some apparently drug-induced code to deal with create time
which isn't being manipulated anyway.
of the Samba4 timezone handling code back into Samba3.
Gets rid of "kludge-gmt" and removes the effectiveness
of the parameter "time offset" (I can add this back
in very easily if needed) - it's no longer being
looked at. I'm hoping this will fix the problems people
have been having with DST transitions. I'll start comprehensive
testing tomorrow, but for now all modifications are done.
Splits time get/set functions into srv_XXX and cli_XXX
as they need to look at different timezone offsets.
Get rid of much of the "efficiency" cruft that was
added to Samba back in the day when the C library
timezone handling functions were slow.
Jeremy.
retrieve the timestamps (Win2k) and not if it used cli-getatr() to retrieve
the timestamps (Win98). Timestamps are supposed to be in GMT, and should
not have serverzone deducted from them in cli_qpathinfo2().
cd up and down the tree and get directory listings.
Still have to figure out how to get a directory listing on a
2k dfs root. Also have to work out some issues with relative paths
that cross dfs mount points.
We're protected from the new code paths when connecting to
a non-dfs root share ( the flag from the tcon&X is stored
in the struct cli_state* )
on an initial open the desired_access field *must* contain DELETE_ACCESS,
simply having it map from a GENERIC_ALL won't do. Fixes delete on close test.
Jeremy.
As well as avoiding DOS charset issues, this scheme returns useful error
codes, that we can map back via the pam interface.
This patch also cleans up the interfaces used for password buffers, to
avoid duplication of code.
Andrew Bartlett
- vorlan's hosts allow with DNS names patch
- use x_fileno() in debug.c, not the struct directly.
- check for server timeout on password change (was reporting success)
- better error/status loggin in both the pam_winbind client and winbindd_pam
server code.
- (pdb_ldap) don't set the ldap version twice - we do it on every bind anyway.
