| * [PATCH] Abnormal End of ProcessesSteve Grubb2007-05-113-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | Hi, I have been working on some code that detects abnormal events based on audit system events. One kind of event that we currently have no visibility for is when a program terminates due to segfault - which should never happen on a production machine. And if it did, you'd want to investigate it. Attached is a patch that collects these events and sends them into the audit system.

| * [PATCH] match audit name dataAmy Griffis2007-05-111-58/+84
| | | | | | | | | | | | | | | | | | Make more effort to detect previously collected names, so we don't log multiple PATH records for a single filesystem object.

| * [PATCH] complete message queue auditingAmy Griffis2007-05-114-35/+5
| | | | | | | | | | | | | | | | | | | | Handle the edge cases for POSIX message queue auditing. Collect inode info when opening an existing mq, and for send/receive operations. Remove audit_inode_update() as it has really evolved into the equivalent of audit_inode(). Signed-off-by: Amy Griffis <amy.griffis@hp.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | Collect inode info for the remaining xattr syscalls that operate on a file descriptor.

| * [PATCH] initialize name osidAmy Griffis2007-05-111-0/+1
| | | | | | | | | | | | | | | | | | Audit contexts can be reused, so initialize a name's osid to the default in audit_getname(). This ensures we don't log a bogus object label when no inode data is collected for a name. Signed-off-by: Amy Griffis <amy.griffis@hp.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
| * [PATCH] audit signal recipientsAmy Griffis2007-05-1111-29/+206
| | | | | | | | | | | | | | | | | | | | | | | | | | When auditing syscalls that send signals, log the pid and security context for each target process. Optimize the data collection by adding a counter for signal-related rules, and avoiding allocating an aux struct unless we have more than one target process. For process groups, collect pid/context data in blocks of 16. Move the audit_signal_info() hook up in check_kill_permission() so we audit attempts where permission is denied.

| * | USB HID: report descriptor of Cypress USB barcode readers needs fixupJiri Kosina2007-05-093-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain versions of Cypress USB barcode readers (this problem is known to happen at least with PIDs 0xde61 and 0xde64) have report descriptor which has swapped usage min and usage max tag. This results in HID parser failing for report descriptor of these devices, as it (wrongly) requires allocating more usages than HID_MAX_USAGES. Solve this by walking through the report descriptor for such devices, and swap the usage min and usage max items (and their values) to be in proper order.

| * | | [NET_SCHED]: Avoid requeue warning on dev_deactivateHerbert Xu2007-05-101-10/+8

This causes a warning to be printed. This patch fixes this by checking this before we requeue. As an added bonus, we can remove the same check in __qdisc_run which was added to prevent dev->gso_skb from being requeued when we're shutting down. Even though we've had to add a new conditional in its place, it's better because it only happens on requeues rather than every single time that qdisc_run is called. For this to work we also need to move the clearing of gso_skb up in dev_deactivate as now qdisc_restart can occur even after we wait for __LINK_STATE_QDISC_RUNNING to clear (but it won't do anything as long as the queue and gso_skb is already clear).

Things have changed quite a bit since then (even Tony Blair is moving on now, not to mention the new French president). All we need to indicate now is whether the caller should continue processing the queue. Therefore it's sufficient if we return 0 if we want to stop and non-zero otherwise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When transmit fails with NETDEV_TX_LOCKED the skb is requeued to dev->qdisc again. The dev->qdisc pointer is protected by the queue lock which needs to be dropped when attempting to transmit and acquired again before requeing. The problem is that qdisc_restart() fetches the dev->qdisc pointer once and stores it in the `q' variable which is invalidated when dropping the queue_lock, therefore the variable needs to be refreshed before requeueing.

In addition, it uses interrupt endpoints instead of bulk ones as the rest of USB IrDA dongles supported by Linux (just to be different?) and data reads need to be parsed to extract the valid bytes before being unwrapped (details in the comment at the start of the source). No speed commands have been discovered for this dongle, and I suspect it does not have any at all. On plugin, this dongle reports vendor and device IDs: 0x07c0:0x4200 . The Windows driver that is used normally to control this dongle has a filename of DSIR620.SYS .

| * | | [NET]: Remove link_watch delay for up even when we're downHerbert Xu2007-05-101-23/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently all link carrier events are delayed by up to a second before they're processed to prevent link storms. This causes unnecessary packet loss during that interval. In fact, we can achieve the same effect in preventing storms by only delaying down events and unnecssary up events. The latter is defined as up events when we're already up. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
| * | | [NET] link_watch: Move link watch list into net_deviceHerbert Xu2007-05-102-35/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These days the link watch mechanism is an integral part of the network subsystem as it manages the carrier status. So it now makes sense to allocate some memory for it in net_device rather than allocating it on demand. In fact, this is necessary because we can't tolerate a memory allocation failure since that means we'd have to potentially throw a link up event away. It also simplifies the code greatly. In doing so I discovered a subtle race condition in the use of singleevent. This race condition still exists (and is somewhat magnified) without singleevent but it's now plugged thanks to an smp_mb__before_clear_bit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally a serial Bluetooth device is opened, TIOSETD'ed to N_HCI line discipline, HCIUARTSETPROTO'ed and finally closed. In case the device fails to HCIUARTSETPROTO, closing it produces a NULL pointer dereference. Signed-off-by: Ohad Ben-Cohen <ohad@bencohen.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
