f3ade83 John Blackwood 26 August 2008, 19:09:43 UTC sched: fix sched_rt_rq_enqueue() resched idle When sysctl_sched_rt_runtime is set to something other than -1 and the CONFIG_RT_GROUP_SCHED kernel parameter is NOT enabled, we get into a state where we see one or more CPUs idling forvever even though there are real-time tasks in their rt runqueue that are able to run (no longer throttled). The sequence is: - A real-time task is running when the timer sets the rt runqueue to throttled, and the rt task is resched_task()ed and switched out, and idle is switched in since there are no non-rt tasks to run on that cpu. - Eventually the do_sched_rt_period_timer() runs and un-throttles the rt runqueue, but we just exit the timer interrupt and go back to executing the idle task in the idle loop forever. If we change the sched_rt_rq_enqueue() routine to use some of the code from the CONFIG_RT_GROUP_SCHED enabled version of this same routine and resched_task() the currently executing task (idle in our case) if it is a lower priority task than the higher rt task in the now un-throttled runqueue, the problem is no longer observed.

f42ac38 Steven Rostedt 27 August 2008, 13:14:40 UTC ftrace: disable tracing for suspend to ram I've been painstakingly debugging the issue with suspend to ram and ftraced. The 2.6.28 code does not have this issue, but since the mcount recording is not going to be in 27, this must be solved for the ftrace daemon version. The resume from suspend to ram would reboot because it was triple faulting. Debugging further, I found that calling the mcount function itself was not an issue, but it would fault when it incremented preempt_count. preempt_count is on the tasks info structure that is on the low memory address of the task's stack. For some reason, it could not write to it. Resuming out of suspend to ram does quite a lot of funny tricks to get to work, so it is not surprising at all that simply doing a preempt_disable() would cause a fault. Thanks to Rafael for suggesting to add a "while (1);" to find the place in resuming that is causing the fault. I would place the loop somewhere in the code, compile and reboot and see if it would either reboot (hit the fault) or simply hang (hit the loop). Doing this over and over again, I narrowed it down that it was happening in enable_nonboot_cpus. At this point, I found that it is easier to simply disable tracing around the suspend code, instead of searching for the particular function that can not handle doing a preempt_disable. This patch disables the tracer as it suspends and reenables it on resume. I tested this patch on my Laptop, and it can resume fine with the patch.

e80d6a2 Mel Gorman 14 August 2008, 10:10:14 UTC [ARM] Skip memory holes in FLATMEM when reading /proc/pagetypeinfo Ordinarily, memory holes in flatmem still have a valid memmap and is safe to use. However, an architecture (ARM) frees up the memmap backing memory holes on the assumption it is never used. /proc/pagetypeinfo reads the whole range of pages in a zone believing that the memmap is valid and that pfn_valid will return false if it is not. On ARM, freeing the memmap breaks the page->zone linkages even though pfn_valid() returns true and the kernel can oops shortly afterwards due to accessing a bogus struct zone *. This patch lets architectures say when FLATMEM can have holes in the memmap. Rather than an expensive check for valid memory, /proc/pagetypeinfo will confirm that the page linkages are still valid by checking page->zone is still the expected zone. The lookup of page_zone is safe as there is a limited range of memory that is accessed when calling page_zone. Even if page_zone happens to return the correct zone, the impact is that the counters in /proc/pagetypeinfo are slightly off but fragmentation monitoring is unlikely to be relevant on an embedded system.

edcfe5f Ayaz Abdulla 20 August 2008, 23:34:37 UTC forcedeth: fix checksum flag Fix the checksum feature advertised in device flags. The hardware support TCP/UDP over IPv4 and TCP/UDP over IPv6 (without IPv6 extension headers). However, the kernel feature flags do not distinguish IPv6 with/without extension headers. Therefore, the driver needs to use NETIF_F_IP_CSUM instead of NETIF_F_HW_CSUM since the latter includes all IPv6 packets. A future patch can be created to check for extension headers and perform software checksum calculation.

45e15bb Santiago Leon 20 August 2008, 19:09:19 UTC ibmveth: fix bad UDP checksums This patch fixes a ibmveth bug where bad UDP checksums are being transmitted when checksum offloading is enabled. The hypervisor does checksum offloading only on TCP packets, so ibmveth calls skb_checksum_help() for any other protocol. The bug happens because the packet is being modified after the DMA map, so we would need a memory barrier before making the hypervisor call. Reordering the code so that the DMA map happens after skb_checksum_help() has the additional advantage of fixing a DMA map leak if skb_checksum_help() where to fail.

76029ff FUJITA Tomonori 25 August 2008, 18:36:08 UTC bio: fix bio_copy_kern() handling of bio->bv_len The commit 68154e90c9d1492d570671ae181d9a8f8530da55 introduced bio_copy_kern() to add bounce support to blk_rq_map_kern. bio_copy_kern() uses bio->bv_len to copy data for READ commands after the completion but it doesn't work with a request that partially completed. SCSI always completes a PC request as a whole but seems some don't. This patch fixes bio_copy_kern to handle the above case. As bio_copy_user does, bio_copy_kern uses struct bio_map_data to store struct bio_vec.

Note: The interface was added in 2.6.17-rc1 and is unused and undocumented so far so it's safe to change it.

abf5439 FUJITA Tomonori 16 August 2008, 05:10:05 UTC block: move cmdfilter from gendisk to request_queue cmd_filter works only for the block layer SG_IO with SCSI block devices. It breaks scsi/sg.c, bsg, and the block layer SG_IO with SCSI character devices (such as st). We hit a kernel crash with them. The problem is that cmd_filter code accesses to gendisk (having struct blk_scsi_cmd_filter) via inode->i_bdev->bd_disk. It works for only SCSI block device files. With character device files, inode->i_bdev leads you to struct cdev. inode->i_bdev->bd_disk->blk_scsi_cmd_filter isn't safe. SCSI ULDs don't expose gendisk; they keep it private. bsg needs to be independent on any protocols. We shouldn't change ULDs to expose their gendisk. This patch moves struct blk_scsi_cmd_filter from gendisk to request_queue, a common object, which eveyone can access to. The user interface doesn't change; users can change the filters via /sys/block/. gendisk has a pointer to request_queue so the cmd_filter code accesses to struct blk_scsi_cmd_filter.

8ab65b0 Jan-Espen Pettersen 25 August 2008, 18:29:22 UTC mac80211: don't send empty extended rates IE The association request includes a list of supported data rates. 802.11b: 4 supported rates. 802.11g: 12 (8 + 4) supported rates. 802.11a: 8 supported rates. The rates tag of the assoc request has room for only 8 rates. In case of 802.11g an extended rate tag is appended. However in net/wireless/mlme.c an extended (empty) rate tag is also appended if the number of rates is exact 8. This empty (length=0) extended rates tag causes some APs to deny association with code 18 (unsupported rates). These APs include my ZyXEL G-570U, and according to Tomas Winkler som Cisco APs. 'If count == 8' has been used to check for the need for an extended rates tag. But count would also be equal to 8 if the for loop exited because of no more supported rates. Therefore a check for count being less than rates_len would seem more correct.

Depending on the vif type, this ended up in corrupting debugfs entries since the dentries inside different union structures ended up going being on top of eachother.. As the end result, debugfs files were being left behind with references to freed data (instant kernel oops on access) and directories were not removed properly when unloading mac80211 drivers.
