2010-03-18charset: fixed a problem with the global use of the iconv_convenience structureAndrew Tridgell3-13/+39
We had a crash bug where a cached copy of a iconv convenience pointer was used after being freed when loadparm asked for iconv to reload. This could happen if a python module used a iconv based function before loadparm was completed. The fix is to ensure that any use of this pointer remains valid, by reusing the pointer itself when it has already been initialised, but filling in the child elements with the updated values.

2010-03-15talloc_stack: make sure we never let talloc_tos() return ts->talloc_stack[-1]Stefan Metzmacher1-1/+1
In smbd there's a small gab between TALLOC_FREE(frame); before be call smbd_parent_loop() where we don't have a valid talloc stackframe. smbd_parent_loop() calls talloc_stackframe() only within the while(1) loop. As DEBUG(2,("waiting for connections")) uses talloc_tos() to construct the time header for the debug message we crash on some systems. metze

2010-02-24tdb: handle processes dying during transaction commit.Rusty Russell3-0/+86
tdb transactions were designed to be robust against the machine powering off, but interestingly were never designed to handle the case where an administrator kill -9's a process during commit. Because recovery is only done on tdb_open, processes with the tdb already mapped will simply use it despite it being corrupt and needing recovery. The solution to this is to check for recovery every time we grab a data lock: we could have gained the lock because a process just died. This has no measurable cost: here is the time for tdbtorture -s 0 -n 1 -l 10000: Before: 2.75 2.50 2.81 3.19 2.91 2.53 2.72 2.50 2.78 2.77 = Avg 2.75 After: 2.81 2.57 3.42 2.49 3.02 2.49 2.84 2.48 2.80 2.43 = Avg 2.74 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2010-02-24tdb: add -k option to tdbtortureRusty Russell1-57/+142
To test the case of death of a process during transaction commit, add a -k (kill random) option to tdbtorture. The easiest way to do this is to make every worker a child (unless there's only one child), which is why this patch is bigger than you might expect. Using -k without -t (always transactions) you expect corruption, though it doesn't happen every time. With -t, we currently get corruption but the next patch fixes that. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: don't truncate tdb on recoveryRusty Russell1-10/+0
The current recovery code truncates the tdb file on recovery. This is fine if recovery is only done on first open, but is a really bad idea as we move to allowing recovery on "live" databases. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: remove lock opsRusty Russell4-40/+22
Now the transaction code uses the standard allrecord lock, that stops us from trying to grab any per-record locks anyway. We don't need to have special noop lock ops for transactions. This is a nice simplification: if you see brlock, you know it's really going to grab a lock. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: rename tdb_release_extra_locks() to tdb_release_transaction_locks()Rusty Russell3-13/+9
tdb_release_extra_locks() is too general: it carefully skips over the transaction lock, even though the only caller then drops it. Change this, and rename it to show it's clearly transaction-specific. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: cleanup: remove ltype argument from _tdb_transaction_cancel.Rusty Russell1-17/+13
Now the transaction allrecord lock is the standard one, and thus is cleaned in tdb_release_extra_locks(), _tdb_transaction_cancel() doesn't need to know what type it is. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: tdb_allrecord_lock/tdb_allrecord_unlock/tdb_allrecord_upgradeRusty Russell3-29/+62
Centralize locking of all chains of the tdb; rename _tdb_lockall to tdb_allrecord_lock and _tdb_unlockall to tdb_allrecord_unlock, and tdb_brlock_upgrade to tdb_allrecord_upgrade. Then we use this in the transaction code. Unfortunately, if the transaction code records that it has grabbed the allrecord lock read-only, write locks will fail, so we treat this upgradable lock as a write lock, and mark it as upgradable using the otherwise-unused offset field. One subtlety: now the transaction code is using the allrecord_lock, the tdb_release_extra_locks() function drops it for us, so we no longer need to do it manually in _tdb_transaction_cancel. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: suppress record write locks when allrecord lock is taken.Rusty Russell1-0/+9
Records themselves get (read) locked by the traversal code against delete. Interestingly, this locking isn't done when the allrecord lock has been taken, though the allrecord lock until recently didn't cover the actual records (it now goes to end of file). The write record lock, grabbed by the delete code, is not suppressed by the allrecord lock. This is now bad: it causes us to punch a hole in the allrecord lock when we release the write record lock. Make this consistent: *no* record locks of any kind when the allrecord lock is taken. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: cleanup: always grab allrecord lock to infinity.Rusty Russell1-7/+3
We were previously inconsistent with our "global" lock: the transaction code grabbed it from FREELIST_TOP to end of file, and the rest of the code grabbed it from FREELIST_TOP to end of the hash chains. Change it to always grab to end of file for simplicity and so we can merge the two. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: remove num_locksRusty Russell2-11/+2
This was redundant before this patch series: it mirrored num_lockrecs exactly. It still does. Also, skip useless branch when locks == 1: unconditional assignment is cheaper anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: use tdb_nest_lock() for seqnum lock.Rusty Russell1-3/+3
This is pure overhead, but it centralizes the locking. Realloc (esp. as most implementations are lazy) is fast compared to the fnctl anyway. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: use tdb_nest_lock() for active lock.Rusty Russell2-5/+18
Use our newly-generic nested lock tracking for the active lock. Note that the tdb_have_extra_locks() and tdb_release_extra_locks() functions have to skip over this lock now it is tracked. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-22tdb: use tdb_nest_lock() for open lock.Rusty Russell3-15/+10
This never nests, so it's overkill, but it centralizes the locking into lock.c and removes the ugly flag in the transaction code to track whether we have the lock or not. Note that we have a temporary hack so this places a real lock, despite the fact that we are in a transaction. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: use tdb_nest_lock() for transaction lock.Rusty Russell2-32/+23
Rather than a boutique lock and a separate nest count, use our newly-generic nested lock tracking for the transaction lock. Note that the tdb_have_extra_locks() and tdb_release_extra_locks() functions have to skip over this lock now it is tracked. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: cleanup: find_nestlock() helper.Rusty Russell1-28/+23
Factor out two loops which find locks; we are going to introduce a couple more so a helper makes sense. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-24tdb: cleanup: tdb_release_extra_locks() helperRusty Russell3-17/+22
Move locking intelligence back into lock.c, rather than open-coding the lock release in transaction.c. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2010-02-17tdb: cleanup: tdb_have_extra_locks() helperRusty Russell4-5/+17
In many places we check whether locks are held: add a helper to do this. The _tdb_lockall() case has already checked for the allrecord lock, so the extra work done by tdb_have_extra_locks() is merely redundant. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
