2010-03-28s3: Fix typos in a debug message in vfs_init_customVolker Lendecke1-1/+2
2010-03-26Revert the part of bug fix #7233 - print fails with jobs >4GB from Win7 clients.Jeremy Allison1-22/+4
Submitter reports print file corruption after 2GB when SMBwrite etc. always write at EOF. Still working on the fix. Jeremy.

2010-03-25Fix bug 7297 - smbd crashes with CUPS printers and no [printers] share defined.Jeremy Allison1-1/+1
Ensure we don't dereference an array with an index of -1. Jeremy.
2010-03-25s3: Add a comment to notify_internal_parent_init, this is pretty confusingVolker Lendecke1-0/+6
2010-03-25s3: Make sure our CLEAR_IF_FIRST optimization works for serverid.tdbVolker Lendecke1-0/+4
In the child, we fully re-open serverid.tdb, which leads to one fcntl lock for CLEAR_IF_FIRST detection per smbd. This opens the tdb in the parent and holds it, so that tdb_reopen_all correctly catches the CLEAR_IF_FIRST bit.
2010-03-25s3: Make sure our CLEAR_IF_FIRST optimization works for the notify tdbsVolker Lendecke2-0/+31
The notify tdb files are opened at tconX time, which leads to one fcntl lock for CLEAR_IF_FIRST detection per smbd. This opens the tdbs in the parent and holds it, so that tdb_reopen_all correctly catches the CLEAR_IF_FIRST bit.

2010-03-22s3: Add "log writeable files on exit" parameterVolker Lendecke1-0/+31
This boolean option controls whether at exit time the server dumps a list of files with debug level 0 that were still open for write. This is an administrative aid to find the files that were potentially corrupt if the network connection died.
2010-03-22s3: file_walk_table -> files_forallVolker Lendecke1-1/+1
This is more in line with the rest of the Samba code, like connections_forall etc.

2010-03-15Fix bug #7188 - Logic error in check of total_data for call_trans2mkdir()Jeremy Allison1-16/+13
Make ea data checks identical for trans2open and trans2mkdir. Jeremy.
2010-03-15Remove reference to conn->admin_user in preparation for removal.Jeremy Allison1-9/+13
We use (uid_t)0 here not sec_initial_uid() as make test uses a single user context. I will revisit this when all the uid check changes are complete. Jeremy.
2010-03-15Simplify processing of "admin user". If a user is an admin_user ensure their ↵Jeremy Allison1-15/+14
conn token is uid 0. This simplifies change_to_user() and removes special processing of the assignments we pass to set_sec_ctx(). Jeremy.

get_current_nttok(conn) Centralize the root check into smb1_file_se_access_check() so this is used by modules/vfs_acl_common.c also. Jeremy.
2010-03-12Remove more uses of "extern struct current_user current_user;".Jeremy Allison7-67/+123
Use accessor functions to get to this value. Tidies up much of the user context code. Volker, please look at the changes in smbd/uid.c to familiarize yourself with these changes as I think they make the logic in there cleaner. Cause smbd/posix_acls.c code to look at current user context, not stored context on the conn struct - allows correct use of these function calls under a become_root()/unbecome_root() pair. Jeremy.

2010-03-10s3: Fix a long-standing problem with recycled PIDsVolker Lendecke2-6/+37
When a samba server process dies hard, it has no chance to clean up its entries in locking.tdb, brlock.tdb, connections.tdb and sessionid.tdb. For locking.tdb and brlock.tdb Samba is robust by checking every time we read an entry from the database if the corresponding process still exists. If it does not exist anymore, the entry is deleted. This is not 100% failsafe though: On systems with a limited PID space there is a non-zero chance that between the smbd's death and the fresh access, the PID is recycled by another long-running process. This renders all files that had been locked by the killed smbd potentially unusable until the new process also dies. This patch is supposed to fix the problem the following way: Every process ID in every database is augmented by a random 64-bit number that is stored in a serverid.tdb. Whenever we need to check if a process still exists we know its PID and the 64-bit number. We look up the PID in serverid.tdb and compare the 64-bit number. If it's the same, the process still is a valid smbd holding the lock. If it is different, a new smbd has taken over. I believe this is safe against an smbd that has died hard and the PID has been taken over by a non-samba process. This process would not have registered itself with a fresh 64-bit number in serverid.tdb, so the old one still exists in serverid.tdb. We protect against this case by the parent smbd taking care of deregistering PIDs from serverid.tdb and the fact that serverid.tdb is CLEAR_IF_FIRST. CLEAR_IF_FIRST does not work in a cluster, so the automatic cleanup does not work when all smbds are restarted. For this, "net serverid wipe" has to be run before smbd starts up. As a convenience, "net serverid wipedbs" also cleans up sessionid.tdb and connections.tdb. While there, this also cleans up overloading connections.tdb with all the process entries just for messaging_send_all(). Volker

2010-03-08Revert "Fix bug #7067 - Linux asynchronous IO (aio) can cause smbd to fail ↵Karolin Seeger1-8/+0
to respond to a read or write." This reverts commit a6ae7a552f851a399991262377cc0e062e40ac20. This fixes bug #7222 (All users have full rigths on all shares) (CVE-2010-0728). (cherry picked from commit 1c9494c76cc9686c61e0966f38528d3318f3176f)
2010-03-05Fix for bug #7189 - Open txt files with notepad on samba shares creates problem.Jeremy Allison7-25/+71
Ensure we don't use any of the create_options for Samba private use. Add a new parameter to the VFS_CREATE call (private_flags) which is only used internally. Renumber NTCREATEX_OPTIONS_PRIVATE_DENY_DOS and NTCREATEX_OPTIONS_PRIVATE_DENY_FCB to match the S4 code). Rev. the VFS interface to version 28. Jeremy.

2010-03-01s3: Add connections_forall_read()Volker Lendecke1-3/+2
In a cluster, this makes a large difference: For r/w traverse, we have to do a fetch_locked on every record which for most users of connections_forall is just overkill.
