| c5d6136 | Thadeu Lima de Souza Cascardo | 10 October 2011, 06:42:23 UTC | mlx4_en: fix endianness with blue frame support The doorbell register was being unconditionally swapped. In x86, that meant it was being swapped to BE and written to the descriptor and to memory, depending on the case of blue frame support or writing to doorbell register. On PPC, this meant it was being swapped to LE and then swapped back to BE while writing to the register. But in the blue frame case, it was being written as LE to the descriptor. The fix is not to swap doorbell unconditionally, write it to the register as BE and convert it to BE when writing it to the descriptor.

The work he has done so far is excellent, and the fact that he works for Nvidia means he has long-term interest in the platform. Erik Gilling did an astounding amount of work on getting things up and running but has been a silent partner on the maintainership side for a while, and is stepping down. Thanks for your contributions so far, Erik. Finally, update the git URL since I'll take over running the main repo for a while. Overall maintainership model isn't changing much at this time: We'll all three review patches as appropriate, and one of us will collect the main repo (me at this time).

Due to the number of issues recently discovered on some x86 chipsets, make this the default behavior. Also, add the option for peer to peer DMA MPS configuration. Peer to peer DMA is outside the scope of this patch, but MPS configuration could prevent it from working by having the MPS on one root port different than the MPS on another. To work around this, simply make the system wide MPS the smallest possible value (128B).

Running with CONFIG_DEBUG_KMEMLEAK pointed to idedisk_prep_fn() which unconditionally allocates an ide_cmd struct. However, ide_requeue_and_plug() can be called more than once per request, either from the request issue or the IRQ handler path and do blk_peek_request() ends up in idedisk_prep_fn() repeatedly, allocating a struct ide_cmd everytime and "forgetting" the previous pointer.

| 7091fbd | Willem de Bruijn | 30 September 2011, 10:38:28 UTC | make PACKET_STATISTICS getsockopt report consistently between ring and non-ring This is a minor change. Up until kernel 2.6.32, getsockopt(fd, SOL_PACKET, PACKET_STATISTICS, ...) would return total and dropped packets since its last invocation. The introduction of socket queue overflow reporting [1] changed drop rate calculation in the normal packet socket path, but not when using a packet ring. As a result, the getsockopt now returns different statistics depending on the reception method used. With a ring, it still returns the count since the last call, as counts are incremented in tpacket_rcv and reset in getsockopt. Without a ring, it returns 0 if no drops occurred since the last getsockopt and the total drops over the lifespan of the socket otherwise. The culprit is this line in packet_rcv, executed on a drop: drop_n_acct: po->stats.tp_drops = atomic_inc_return(&sk->sk_drops); As it shows, the new drop number it taken from the socket drop counter, which is not reset at getsockopt. I put together a small example that demonstrates the issue [2]. It runs for 10 seconds and overflows the queue/ring on every odd second. The reported drop rates are: ring: 16, 0, 16, 0, 16, ... non-ring: 0, 15, 0, 30, 0, 46, 0, 60, 0 , 74. Note how the even ring counts monotonically increase. Because the getsockopt adds tp_drops to tp_packets, total counts are similarly reported cumulatively. Long story short, reinstating the original code, as the below patch does, fixes the issue at the cost of additional per-packet cycles. Another solution that does not introduce per-packet overhead is be to keep the current data path, record the value of sk_drops at getsockopt() at call N in a new field in struct packetsock and subtract that when reporting at call N+1. I'll be happy to code that, instead, it's just more messy.

Without this initial kick the frontend just adds Tx requests to the ring without raising an event (until the ring is full). This was caused by 47103041e91794acdbc6165da0ae288d844c820b (net: xen-netback: convert to hw_features) which reordered the calls to xenvif_up() and netif_carrier_on() in xenvif_connect().

| a0db2da | Andy Gospodarek | 23 September 2011, 10:53:34 UTC | bonding: properly stop queuing work when requested During a test where a pair of bonding interfaces using ARP monitoring were both brought up and torn down (with an rmmod) repeatedly, a panic in the timer code was noticed. I tracked this down and determined that any of the bonding functions that ran as workqueue handlers and requeued more work might not properly exit when the module was removed. There was a flag protected by the bond lock called kill_timers that is set when the interface goes down or the module is removed, but many of the functions that monitor link status now unlock the bond lock to take rtnl first. There is a chance that another CPU running the rmmod could get the lock and set kill_timers after the first check has passed. This patch does not allow any function to queue work that will make itself run unless kill_timers is not set. I also noticed while doing this work that bond_resend_igmp_join_requests did not have a check for kill_timers, so I added the needed call there as well.

I debugged this down to the abort handling improperly treating a command of type SRB_ADISC_CMD as if it had a bsg_job to complete when that command actually uses the iocb_cmd part of the union. (I guess to hit this one has to unload the module while the async FC initialization is still in progress) It seems we should only look for a bsg_job if type is SRB_ELS_CMD_RPT, SRB_ELS_CMD_HST or SRB_CT_CMD, so switch the test to make that explicit.

| b631642 | Josef Bacik | 30 September 2011, 19:23:54 UTC | Btrfs: force a page fault if we have a shorty copy on a page boundary A user reported a problem where ceph was getting into 100% cpu usage while doing some writing. It turns out it's because we were doing a short write on a not uptodate page, which means we'd fall back at one page at a time and fault the page in. The problem is our position is on the page boundary, so our fault in logic wasn't actually reading the page, so we'd just spin forever or until the page got read in by somebody else. This will force a readpage if we end up doing a short copy. Alexandre could reproduce this easily with ceph and reports it fixes his problem.

Software must keep MMC1_PBIAS cell and MMC1_IO cell PWRDNZ signals low whenever SDMMC1_VDDS ramps up/down or changes for cell protection purposes.

Just build it with "gcc -o test test.c -lpthread -lrt" or similar. Run it several times, and you will see cases where the main thread will measure a process clock difference before and after the nanosleep which is smaller than the cpu-burner thread's individual thread clock difference. This doesn't make any sense since the cpu-burner thread is part of the top-level process's thread group. I've reproduced this on both x86-64 and sparc64 (using both 32-bit and 64-bit binaries). For example: [davem@boricha build-x86_64-linux]$ ./test process: before(0.001221967) after(0.498624371) diff(497402404) thread: before(0.000081692) after(0.498316431) diff(498234739) self: before(0.001223521) after(0.001240219) diff(16698) [davem@boricha build-x86_64-linux]$ The diff of 'process' should always be >= the diff of 'thread'. I make sure to wrap the 'thread' clock measurements the most tightly around the nanosleep() call, and that the 'process' clock measurements are the outer-most ones. --- #include <unistd.h> #include <stdio.h> #include <stdlib.h> #include <time.h> #include <fcntl.h> #include <string.h> #include <errno.h> #include <pthread.h> static pthread_barrier_t barrier; static void *chew_cpu(void *arg) { pthread_barrier_wait(&barrier); while (1) __asm__ __volatile__("" : : : "memory"); return NULL; } int main(void) { clockid_t process_clock, my_thread_clock, th_clock; struct timespec process_before, process_after; struct timespec me_before, me_after; struct timespec th_before, th_after; struct timespec sleeptime; unsigned long diff; pthread_t th; int err; err = clock_getcpuclockid(0, &process_clock); if (err) return 1; err = pthread_getcpuclockid(pthread_self(), &my_thread_clock); if (err) return 1; pthread_barrier_init(&barrier, NULL, 2); err = pthread_create(&th, NULL, chew_cpu, NULL); if (err) return 1; err = pthread_getcpuclockid(th, &th_clock); if (err) return 1; pthread_barrier_wait(&barrier); err = clock_gettime(process_clock, &process_before); if (err) return 1; err = clock_gettime(my_thread_clock, &me_before); if (err) return 1; err = clock_gettime(th_clock, &th_before); if (err) return 1; sleeptime.tv_sec = 0; sleeptime.tv_nsec = 500000000; nanosleep(&sleeptime, NULL); err = clock_gettime(th_clock, &th_after); if (err) return 1; err = clock_gettime(my_thread_clock, &me_after); if (err) return 1; err = clock_gettime(process_clock, &process_after); if (err) return 1; diff = process_after.tv_nsec - process_before.tv_nsec; printf("process: before(%lu.%.9lu) after(%lu.%.9lu) diff(%lu)\n", process_before.tv_sec, process_before.tv_nsec, process_after.tv_sec, process_after.tv_nsec, diff); diff = th_after.tv_nsec - th_before.tv_nsec; printf("thread: before(%lu.%.9lu) after(%lu.%.9lu) diff(%lu)\n", th_before.tv_sec, th_before.tv_nsec, th_after.tv_sec, th_after.tv_nsec, diff); diff = me_after.tv_nsec - me_before.tv_nsec; printf("self: before(%lu.%.9lu) after(%lu.%.9lu) diff(%lu)\n", me_before.tv_sec, me_before.tv_nsec, me_after.tv_sec, me_after.tv_nsec, diff); return 0; } This is due to us using p->se.sum_exec_runtime in thread_group_cputime() where we iterate the thread group and sum all data. This does not take time since the last schedule operation (tick or otherwise) into account. We can cure this by using task_sched_runtime() at the cost of having to take locks. This also means we can (and must) do away with thread_group_sched_runtime() since the modified thread_group_cputime() is now more accurate and would deadlock when called from thread_group_sched_runtime(). Aside of that it makes the function safe on 32 bit systems. The old code added t->se.sum_exec_runtime unprotected. sum_exec_runtime is a 64bit value and could be changed on another cpu at the same time.

| 47ea91b | Ram Pai | 22 September 2011, 07:48:58 UTC | Resource: fix wrong resource window calculation __find_resource() incorrectly returns a resource window which overlaps an existing allocated window. This happens when the parent's resource-window spans 0x00000000 to 0xffffffff and is entirely allocated to all its children resource-windows. __find_resource() looks for gaps in resource allocation among the children resource windows. When it encounters the last child window it blindly tries the range next to one allocated to the last child. Since the last child's window ends at 0xffffffff the calculation overflows, leading the algorithm to believe that any window in the range 0x0000000 to 0xfffffff is available for allocation. This leads to a conflicting window allocation. Michal Ludvig reported this issue seen on his platform. The following patch fixes the problem and has been verified by Michal.

So maybe we could start usermodehelper_enable a little early to make some task work that need eary init with the help of user mode. [ I would *really* prefer that initcalls not call into user space - even the real 'init' hasn't been execve'd yet, after all! But for uvesafb it really does look like we don't have much choice. I considered doing this when we mount the root filesystem, but depending on config options that is in multiple places. We could do the usermode helper enable as a rootfs_initcall()..

It turned out that the original code needed to be re-ordered to reduce complexity and to finally fix the reported frame counting issues.

| 8e303f2 | Jiri Olsa | 29 September 2011, 15:05:08 UTC | perf tools: Fix raw sample reading Wrong pointer is being passed for raw data sanity checking, when parsing sample event. This ends up with invalid event and perf record being stuck in __perf_session__process_events function during processing build IDs (process_buildids function). Following command hangs up in my setup: ./perf record -e raw_syscalls:sys_enter ls The fix is to use proper pointer to the raw data instead of the 'u' union.

| f4142cb | David S. Miller | 29 September 2011, 19:18:59 UTC | sparc64: Force the execute bit in OpenFirmware's translation entries. In the OF 'translations' property, the template TTEs in the mappings never specify the executable bit. This is the case even though some of these mappings are for OF's code segment. Therefore, we need to force the execute bit on in every mapping. This problem can only really trigger on Niagara/sun4v machines and the history behind this is a little complicated. Previous to sun4v, the sun4u TTE entries lacked a hardware execute permission bit. So OF didn't have to ever worry about setting anything to handle executable pages. Any valid TTE loaded into the I-TLB would be respected by the chip. But sun4v Niagara chips have a real hardware enforced executable bit in their TTEs. So it has to be set or else the I-TLB throws an instruction access exception with type code 6 (protection violation). We've been extremely fortunate to not get bitten by this in the past. The best I can tell is that the OF's mappings for it's executable code were mapped using permanent locked mappings on sun4v in the past. Therefore, the fact that we didn't have the exec bit set in the OF translations we would use did not matter in practice. Thanks to Greg Onufer for helping me track this down. Signed-off-by: David S.

| 85a6488 | Jonathan Lallinger | 29 September 2011, 07:58:41 UTC | RDSRDMA: Fix cleanup of rds_iw_mr_pool In the rds_iw_mr_pool struct the free_pinned field keeps track of memory pinned by free MRs. While this field is incremented properly upon allocation, it is never decremented upon unmapping. This would cause the rds_rdma module to crash the kernel upon unloading, by triggering the BUG_ON in the rds_iw_destroy_mr_pool function. This change keeps track of the MRs that become unpinned, so that free_pinned can be decremented appropriately.

| f75159e | Richard Cochran | 20 September 2011, 01:25:41 UTC | ptp: fix L2 event message recognition The IEEE 1588 standard defines two kinds of messages, event and general messages. Event messages require time stamping, and general do not. When using UDP transport, two separate ports are used for the two message types. The BPF designed to recognize event messages incorrectly classifies L2 general messages as event messages. This commit fixes the issue by extending the filter to check the message type field for L2 PTP packets. Event messages are be distinguished from general messages by testing the "general" bit.

| d5767c5 | Linus Torvalds | 28 September 2011, 17:23:44 UTC | bootup: move 'usermodehelper_enable()' to the end of do_basic_setup() Doing it just before starting to call into cpu_idle() made a sick kind of sense only because the original bug we fixed (see commit 288d5abec831: "Boot up with usermodehelper disabled") was about problems with some scheduler data structures not being initialized, and they had better be initialized at that point. But it really didn't make any other conceptual sense, and doing it after the initial "schedule()" call for the idle thread actually opened up a race: what if the main initialization thread did everything without needing to sleep, and got all the way into user land too? Without actually having scheduled back to the idle thread? Now, in normal circumstances that doesn't ever happen, but it looks like Richard Cochran triggered exactly that on his ARM IXP4xx machines: "I have some ARM IXP4xx based machines that use the two on chip MAC ports (aka NPEs). The NPE needs a firmware in order to function. Ever since the following commit [that 288d5abec831 one], it is no longer possible to bring up the interfaces during the init scripts." with a call trace showing an ioctl coming from user space. Richard says: "The init is busybox, and the startup script does mount, syslogd, and then ifup, so that all can go by quickly." The fix is to move the usermodehelper_enable() into the main 'init' thread, and just put it after we've done all our initcalls. By then, everything really should be up, but we've obviously not actually started the user-mode portion of init yet.

| 8adc8b3 | Sage Weil | 28 September 2011, 17:11:04 UTC | libceph: fix pg_temp mapping update The incremental map updates have a record for each pg_temp mapping that is to be add/updated (len > 0) or removed (len == 0).
