2010-02-11Fine changes to previous fix for bug #7104 - "wide links" and "unix ↵Jeremy Allison1-20/+18
extensions" are incompatible. Make sure we match the previous allow widelinks behavior, in that non-root preexec scripts can create share directories for a share definition. Jeremy
2010-02-11Suplementary patch for bug #7104 - "wide links" and "unix extensions" are ↵Jeremy Allison1-27/+28
incompatible. Bug reported by Ralf Zimmermann <r.zimmermann@siegnetz.de>. Reproduced by jra. If the target directory of a share doesn't exist, but is designed to be created by a "root preexec" script call, then the widelinks check is done too early - thus preventing the user from connecting to the share. Fix is to re-arrange the order of checks in make_connection_snum() to always do the following order of operations: (1). Turn off wide links if unix extensions = yes. (2). Call any root preexec scripts. (3). Canonicalize the share path to remove any symlinks (ie. end up with the realpath in the connection_struct). Jeremy.

2010-02-09Fix bug #7122 - Reading a large browselist fails (server returns invalid ↵Jeremy Allison2-3/+6
values in subsequent SMBtrans replies) There are two problems: 1). The server is off-by-one in the end of buffer space test. 2). The server returns 0 in the totaldata (smb_vwv1) and totalparams (smb_vwv0) fields in the second and subsequent SMBtrans replies. This patch fixes both. Jeremy.

2010-02-05s3-smbd: add a rate limited cleanup of brl, connections and locking dbAndrew Tridgell1-6/+42
On unclean shutdown we can end up with stale entries in the brlock, connections and locking db. Previously we would do the cleanup on every unclean exit, but that can cause smbd to be completely unavailable for several minutes when a large number of child smbd processes exit. This adds a rate limited cleanup of the databases, with the default that cleanup happens at most every 20s
2010-02-05s3-brlock: we don't need these MSG_SMB_UNLOCK calls nowAndrew Tridgell1-2/+0
These have been replaced with the min timeout in blocking.c
2010-02-05s3-brlock: add a minimim retry time for pending blocking locksAndrew Tridgell1-0/+20
When we are waiting on a pending byte range lock, another smbd might exit uncleanly, and therefore not notify us of the removal of the lock, and thus not trigger the lock to be retried. We coped with this up to now by adding a message_send_all() in the SIGCHLD and cluster reconfigure handlers to send a MSG_SMB_UNLOCK to all smbd processes. That would generate O(N^2) work when a large number of clients disconnected at once (such as on a network outage), which could leave the whole system unusable for a very long time (many minutes, or even longer). By adding a minimum re-check time for pending byte range locks we avoid this problem by ensuring that pending locks are retried at a more regular interval.

2010-02-05Fix bug 7104 - "wide links" and "unix extensions" are incompatible.Jeremy Allison3-37/+9
Change parameter "wide links" to default to "no". Ensure "wide links = no" if "unix extensions = yes" on a share. Fix man pages to refect this. Remove "within share" checks for a UNIX symlink set - even if widelinks = no. The server will not follow that link anyway. Correct DEBUG message in check_reduced_name() to add missing "\n" so it's really clear when a path is being denied as it's outside the enclosing share path. Jeremy.

2010-02-01Fix bug #7080 - Quota only shown when logged as root.Jeremy Allison1-1/+1
conn->server_info->utok.uid == 0 isn't the correct check to see if we're root anymore. As rpc_samr_nt.c does, the correct check is : geteuid() == sec_initial_uid() Jeremy.
2010-01-30s3/smbd: Fix string buffer overflow causing heap corruptionSteven Danneman1-1/+2
The destname malloc size was not taking into account the 1 extra byte needed if a string without a leading '/' was passed in and that slash was added. This would cause the '\0' byte to be written past the end of the malloced destname string and corrupt whatever heap memory was there. This problem would be hit if a share name was given in smb.conf without a leading '/' and if it was the exact size of the allocated STRDUP memory which in some implementations of malloc is a power of 2.

2010-01-12Fix bug #7033 - SMBrmdir call always returns true, even on failure to delete ↵Jeremy Allison1-2/+6
a directory. Argh. Missed the second (and essential) part of the fix for the above :-(. Jeremy
2010-01-12Fix bug #7033 - SMBrmdir call always returns true, even on failure to delete ↵Jeremy Allison1-2/+6
a directory. There is a codepath missing to propagate back error returns from the rmdir POSIX call inside close_directory when delete on close is set. This means doing an rmdir on a Windows command line will always report success, even when the directory was not deleted. This fix adds that codepath back into Samba. Jeremy.
2010-01-12Fix bug #6876 - Delete of an object whose parent folder does not have delete ↵Jeremy Allison2-3/+7
rights fails even if the delete right is set on the object. Final fix for the vfs_acl_xattr and vfs_acl_tdb code. Ensure we can delete a file even if the underlying POSIX permissions don't allow it, if the Windows permissions do. Jeremy.

2010-01-08Re-fix bug 5202 - cannot change ACLs on writable file with "dos filemode=yes"Jeremy Allison1-0/+3
This bug re-occurred for 3.3.x and above. The reason is that to change a NT ACL we now have to open the file requesting WRITE_DAC and WRITE_OWNER access. The mapping from POSIX "w" to NT permissions in posix_acls doesn't add these bits when "dos filemode = yes", so even though the permission or owner change would be allowed by the POSIX ACL code, the NTCreateX call fails with ACCESS_DENIED now we always check NT permissions first. Added in the mapping from "w" to WRITE_DAC and WRITE_OWNER access. Jeremy.
2010-01-07s3:smbd:password_in_history: treat entry with 0 salt as 0 + plain nt hashMichael Adam1-6/+24
This is to introduce a new format of the password history, maintaining backwards compatibility: The old format was 16 byte hash + 16 byte md5(salt + nt hash). The new format is 16 zero bytes and 16 bytes nt hash. This will allow us to respect the last X entries of the nt password history when deciding whether to increment the bad password count. This is part of the fix for bug #4347 . Michael
2010-01-07s3: Remove some code that has become unnecessaryVolker Lendecke1-8/+0
The code I just removed was checked in with e5466fffc286a99f as a bug fix for https://bugzilla.samba.org/show_bug.cgi?id=3319. With the changes to is_visible_file made with 9e8b8f8c16612 these lines have become unnecessary, even with "hide unreadable = yes" dead msdfs symlinks show. This is because we can not stat(2) them and default to showing them. Why this change? I have a user who wants to use "hide unreadable" on msdfs links. Because you can't edit acls on symlinks themselves, the user created the targets as bogus, empty files that just exist as acl placeholders. With the code in place that this patch removes, we never allow this to work. Jeremy, please check! :-) Thanks, Volker
