* | | [PATCH] Fix ppc64 smu driver lockingBenjamin Herrenschmidt2005-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SMU driver has a small mistake in the locking of the interrupt code, if polled access and interrupt access race, interrupt may take a lock and return without releasing it. This fixes it. With that patch, the driver is rock solid with my experimental thermal control (which bangs it pretty hard) racing with real time clock and cpufreq handling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attempt to fixup the lockless mce log buffer introduced an infinite loop when trying to find a free entry. And: Using rcu_dereference() to load mcelog.next doesn't seem to be sufficient enough to ensure that mcelog.next is loaded each time around the loop in mce_log(). Instead, use an explicit rmb() to ensure that the compiler gets it right. AK: turned the smp_wmbs into true wmbs to make sure they are not reordered by the compiler on UP.

See also wait_task_stopped(), which checks ->state > TASK_STOPPED. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> [ We really probably should always use the appropriate bitmasks to test task states, not do it like this. Using something like #define TASK_RUNNABLE (TASK_RUNNING | TASK_INTERRUPTIBLE | \ TASK_UNINTERRUPTIBLE | TASK_NONINTERACTIVE) and then doing "if (task->state & TASK_RUNNABLE)" or similar. But the ordering of the task states is historical, and keeping the ordering does make sense regardless. ] Signed-off-by: Linus Torvalds <torvalds@osdl.org>

In kernel 2.4 it was working fine. The bug first occured 4 years ago when switching to new SNAP layer handling. This bug can be splitted up into a sending(1) and reception(2) problem: Sending(1) In kernel 2.4 broadcast packets were sent to a matching ethernet device and atalk_rcv() was called to receive it as "loopback" (so loopback packets were shortcutted and handled in DDP layer). When switching to the new SNAP structure, this shortcut was removed and the loopback packet was send to SNAP layer. The author forgot to replace the remote device pointer by the loopback device pointer before sending the packet to SNAP layer (by calling ddp_dl->request() ) therfor the packet was not sent back by underlying layers to ddp's atalk_rcv(). Reception(2) In atalk_rcv() a packet received by this loopback mechanism contains now the (rigth) loopback device pointer (in Kernel 2.4 it was the (wrong) remote ethernet device pointer) and therefor no matching socket will be found to deliver this packet to. Because a broadcast packet should be send to the first matching socket (as it is done in many other protocols (?)), we removed the network comparison in broadcast case.

| * | | [NET]: Fix module reference counts for loadable protocol modulesFrank Filz2005-09-27

The first issue was that __module_get failed at the BUG_ON check at the top of the routine (checking that my module reference count was not zero) when I created the first socket. When sk_alloc() is called, my module reference count was still 0. When I looked at why sctp didn't have this problem, I discovered that sctp creates a control socket during module init (when the module ref count is not 0), which keeps the reference count non-zero. This section has been updated to address the point Stephen raised about checking the return value of try_module_get(). The next problem arose when my socket init routine returned an error. This resulted in my module reference count being decremented below 0. My socket ops->release routine was also being called. The issue here is that sock_release() calls the ops->release routine and decrements the ref count if sock->ops is not NULL. Since the socket probably didn't get correctly initialized, this should not be done, so we will set sock->ops to NULL because we will not call try_module_get(). While searching for another bug, I also noticed that sys_accept() has a possibility of doing a module_put() when it did not do an __module_get so I re-ordered the call to security_socket_accept().
