* [PATCH] Fix task state testing properly in do_signal_stop()Roland McGrath2005-09-29
| | | | | | | | | | | Any tests using < TASK_STOPPED or the like are left over from the time when the TASK_ZOMBIE and TASK_DEAD bits were in the same word, and it served to check for "stopped or dead". I think this one in do_signal_stop is the only such case. It has been buggy ever since exit_state was separated, and isn't testing the exit_state value.

* Revert task flag re-ordering, add commentsLinus Torvalds2005-09-29
| | | | | | | | | | Roland points out that the flags end up having non-obvious dependencies elsewhere, so revert aa55a08687059aa169d10a313c41f238c2070488 and add some comments about why things are as they are. We'll just have to fix up the broken comparisons. Roland has a patch. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] fix TASK_STOPPED vs TASK_NONINTERACTIVE interactionOleg Nesterov2005-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | do_signal_stop: for_each_thread(t) { if (t->state < TASK_STOPPED) ++sig->group_stop_count; } However, TASK_NONINTERACTIVE > TASK_STOPPED, so this loop will not count TASK_INTERRUPTIBLE | TASK_NONINTERACTIVE threads. 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>

| * | [APPLETALK]: Fix broadcast bug.Oliver Dawid2005-09-27

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
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have been experimenting with loadable protocol modules, and ran into several issues with module reference counting. 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().

This makes SUID binaries easier to support without going as far as labelling keys and key targets using the LSM facilities. This patch adds a second "pointer type" to key structures (struct key_ref *) that can have the bottom bit of the address set to indicate the possession of a key. This is propagated through searches from the keyring to the discovered key. It has been made a separate type so that the compiler can spot attempts to dereference a potentially incorrect pointer. The "possession" attribute can't be attached to a key structure directly as it's not an intrinsic property of a key. Pointers to keys have been replaced with struct key_ref *'s wherever possession information needs to be passed through. This does assume that the bottom bit of the pointer will always be zero on return from kmem_cache_alloc(). The key reference type has been made into a typedef so that at least it can be located in the sources, even though it's basically a pointer to an undefined type. I've also renamed the accessor functions to be more useful, and all reference variables should now end in "_ref".
