2007-05-11[MIPS] Run checksyscalls for N32 and O32 ABIAtsushi Nemoto
On 64-bit MIPS, only N64 ABI is checked by default. This patch adds some rules for other ABIs.

2007-05-11When stacked block devices are in-use (e.g. md or dm), the recursive callsNeil Brown
to generic_make_request can use up a lot of space, and we would rather they didn't. As generic_make_request is a void function, and as it is generally not expected that it will have any effect immediately, it is safe to delay any call to generic_make_request until there is sufficient stack space available. As ->bi_next is reserved for the driver to use, it can have no valid value when generic_make_request is called, and as __make_request implicitly assumes it will be NULL (ELEVATOR_BACK_MERGE fork of switch) we can be certain that all callers set it to NULL. We can therefore safely use bi_next to link pending requests together, providing we clear it before making the real call. So, we choose to allow each thread to only be active in one generic_make_request at a time. If a subsequent (recursive) call is made, the bio is linked into a per-thread list, and is handled when the active call completes. As the list of pending bios is per-thread, there are no locking issues to worry about. I say above that it is "safe to delay any call...". There are, however, some behaviours of a make_request_fn which would make it unsafe. These include any behaviour that assumes anything will have changed after a recursive call to generic_make_request. These could include: - waiting for that call to finish and call it's bi_end_io function. md use to sometimes do this (marking the superblock dirty before completing a write) but doesn't any more - inspecting the bio for fields that generic_make_request might change, such as bi_sector or bi_bdev. It is hard to see a good reason for this, and I don't think anyone actually does it. - inspecing the queue to see if, e.g. it is 'full' yet. Again, I think this is very unlikely to be useful, or to be done. Signed-off-by: Neil Brown <neilb@suse.de> Cc: Jens Axboe <axboe@kernel.dk> Cc: <dm-devel@redhat.com> Alasdair G Kergon <agk@redhat.com> said: I can see nothing wrong with this in principle. For device-mapper at the moment though it's essential that, while the bio mappings may now get delayed, they still get processed in exactly the same order as they were passed to generic_make_request(). My main concern is whether the timing changes implicit in this patch will make the rare data-corrupting races in the existing snapshot code more likely. (I'm working on a fix for these races, but the unfinished patch is already several hundred lines long.) It would be helpful if some people on this mailing list would test this patch in various scenarios and report back.

2007-05-11[PATCH] Abnormal End of ProcessesSteve Grubb
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.

2007-05-11[PATCH] audit signal recipientsAmy Griffis
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.

2007-05-10[NET_SCHED]: Avoid requeue warning on dev_deactivateHerbert Xu
When we relinquish queue_lock in qdisc_restart and then retake it for requeueing, we might race against dev_deactivate and end up requeueing onto noop_qdisc. 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).

2007-05-10[NET_SCHED]: Reread dev->qdisc for NETDEV_TX_OKHerbert Xu

2007-05-10[NET_SCHED]: Rationalise return value of qdisc_restartHerbert Xu
The current return value scheme and associated comment was invented back in the 20th century when we still had that tbusy flag. 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. This is based on a patch by Krishna Kumar. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-05-10[NET]: Fix dev->qdisc race for NETDEV_TX_LOCKED caseThomas Graf
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.

2007-05-10[IrDA]: KingSun/DonShine USB IrDA dongle support.Alex Villac�s Lasso
This dongle does not follow the usb-irda specification, so it needs its own special driver. 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 .
