commit 2fe121e1 upstream. The rtc user must wait at least 1 sec between each time/calandar update (see atmel's datasheet chapter "Updating Time/Calendar"). Use the 1Hz interrupt to update the at91_rtc_upd_rdy flag and wait for the at91_rtc_wait_upd_rdy event if the rtc is not ready. This patch fixes a deadlock in an uninterruptible wait when the RTC is updated more than once every second. AFAICT the bug is here from the beginning, but I think we should at least backport this fix to 3.10 and the following longterm and stable releases. Signed-off-by:

commit 49e068f0 upstream. The compaction freepage scanner implementation in isolate_freepages() starts by taking the current cc->free_pfn value as the first pfn. In a for loop, it scans from this first pfn to the end of the pageblock, and then subtracts pageblock_nr_pages from the first pfn to obtain the first pfn for the next for loop iteration. This means that when cc->free_pfn starts at offset X rather than being aligned on pageblock boundary, the scanner will start at offset X in all scanned pageblock, ignoring potentially many free pages. Currently this can happen when a) zone's end pfn is not pageblock aligned, or b) through zone->compact_cached_free_pfn with CONFIG_HOLES_IN_ZONE enabled and a hole spanning the beginning of a pageblock This patch fixes the problem by aligning the initial pfn in isolate_freepages() to pageblock boundary. This also permits replacing the end-of-pageblock alignment within the for loop with a simple pageblock_nr_pages increment. Signed-off-by:

commit 7ed695e0 upstream. Compaction of a zone is finished when the migrate scanner (which begins at the zone's lowest pfn) meets the free page scanner (which begins at the zone's highest pfn). This is detected in compact_zone() and in the case of direct compaction, the compact_blockskip_flush flag is set so that kswapd later resets the cached scanner pfn's, and a new compaction may again start at the zone's borders. The meeting of the scanners can happen during either scanner's activity. However, it may currently fail to be detected when it occurs in the free page scanner, due to two problems. First, isolate_freepages() keeps free_pfn at the highest block where it isolated pages from, for the purposes of not missing the pages that are returned back to allocator when migration fails. Second, failing to isolate enough free pages due to scanners meeting results in -ENOMEM being returned by migrate_pages(), which makes compact_zone() bail out immediately without calling compact_finished() that would detect scanners meeting. This failure to detect scanners meeting might result in repeated attempts at compaction of a zone that keep starting from the cached pfn's close to the meeting point, and quickly failing through the -ENOMEM path, without the cached pfns being reset, over and over. This has been observed (through additional tracepoints) in the third phase of the mmtests stress-highalloc benchmark, where the allocator runs on an otherwise idle system. The problem was observed in the DMA32 zone, which was used as a fallback to the preferred Normal zone, but on the 4GB system it was actually the largest zone. The problem is even amplified for such fallback zone - the deferred compaction logic, which could (after being fixed by a previous patch) reset the cached scanner pfn's, is only applied to the preferred zone and not for the fallbacks. The problem in the third phase of the benchmark was further amplified by commit 81c0a2bb ("mm: page_alloc: fair zone allocator policy") which resulted in a non-deterministic regression of the allocation success rate from ~85% to ~65%. This occurs in about half of benchmark runs, making bisection problematic. It is unlikely that the commit itself is buggy, but it should put more pressure on the DMA32 zone during phases 1 and 2, which may leave it more fragmented in phase 3 and expose the bugs that this patch fixes. The fix is to make scanners meeting in isolate_freepage() stay that way, and to check in compact_zone() for scanners meeting when migrate_pages() returns -ENOMEM. The result is that compact_finished() also detects scanners meeting and sets the compact_blockskip_flush flag to make kswapd reset the scanner pfn's. The results in stress-highalloc benchmark show that the "regression" by commit 81c0a2bb in phase 3 no longer occurs, and phase 1 and 2 allocation success rates are also significantly improved.

commit d3132e4b upstream. Compaction caches pfn's for its migrate and free scanners to avoid scanning the whole zone each time. In compact_zone(), the cached values are read to set up initial values for the scanners. There are several situations when these cached pfn's are reset to the first and last pfn of the zone, respectively. One of these situations is when a compaction has been deferred for a zone and is now being restarted during a direct compaction, which is also done in compact_zone(). However, compact_zone() currently reads the cached pfn's *before* resetting them. This means the reset doesn't affect the compaction that performs it, and with good chance also subsequent compactions, as update_pageblock_skip() is likely to be called and update the cached pfn's to those being processed. Another chance for a successful reset is when a direct compaction detects that migration and free scanners meet (which has its own problems addressed by another patch) and sets update_pageblock_skip flag which kswapd uses to do the reset because it goes to sleep. This is clearly a bug that results in non-deterministic behavior, so this patch moves the cached pfn reset to be performed *before* the values are read. Signed-off-by:

commit 79d59d08 upstream. In non-leading connection login, iscsi_login_non_zero_tsih_s1() calls iscsi_change_param_value() with the buffer it uses to hold the login PDU, not a temporary buffer. This leads to the login header getting corrupted and login failing for non-leading connections in MC/S. Fix this by adding a wrapper iscsi_change_param_sprintf() that handles the temporary buffer itself to avoid confusion. Also handle sending a reject in case of failure in the wrapper, which lets the calling code get quite a bit smaller and easier to read. Finally, bump the size of the temporary buffer from 32 to 64 bytes to be safe, since "MaxRecvDataSegmentLength=" by itself is 25 bytes; with a trailing NUL, a value >= 1M will lead to a buffer overrun. (This isn't the default but we don't need to run right at the ragged edge here) (Fix up context changes for v3.10.y - nab) Reported-by:

commit 14f4b54f upstream. When the target is in stop stage, iSER transport initiates RDMA disconnects. The iSER initiator may wish to establish a new connection over the still existing network portal. In this case iSER transport should not accept and resume new RDMA connections. In order to learn that, iscsi_np is added with enabled flag so the iSER transport can check when deciding weather to accept and resume a new connection request. The iscsi_np is enabled after successful transport setup, and disabled before iscsi_np login threads are cleaned up. (Fix up context changes for v3.10.y - nab) Signed-off-by:

commit 895162b1 upstream. else we may fail to forward skb even if original fragments do fit outgoing link mtu: 1. remote sends 2k packets in two 1000 byte frags, DF set 2. we want to forward but only see '2k > mtu and DF set' 3. we then send icmp error saying that outgoing link is 1500 But original sender never sent a packet that would not fit the outgoing link. Setting local_df makes outgoing path test size vs. IPCB(skb)->frag_max_size, so we will still send the correct error in case the largest original size did not fit outgoing link mtu. Reported-by:

commit 14c63f17 upstream. This patch keeps track of how long perf's NMI handler is taking, and also calculates how many samples perf can take a second. If the sample length times the expected max number of samples exceeds a configurable threshold, it drops the sample rate. This way, we don't have a runaway sampling process eating up the CPU. This patch can tend to drop the sample rate down to level where perf doesn't work very well. *BUT* the alternative is that my system hangs because it spends all of its time handling NMIs. I'll take a busted performance tool over an entire system that's busted and undebuggable any day. BTW, my suspicion is that there's still an underlying bug here. Using the HPET instead of the TSC is definitely a contributing factor, but I suspect there are some other things going on. But, I can't go dig down on a bug like that with my machine hanging all the time. Signed-off-by:

commit 6cc44a6f upstream. This patch addresses a bug where an early exception for SCSI WRITE with ImmediateData=Yes was missing the target_put_sess_cmd() call to drop the extra se_cmd->cmd_kref reference obtained during the normal iscsit_setup_scsi_cmd() codepath execution. This bug was manifesting itself during session shutdown within isert_cq_rx_comp_err() where target_wait_for_sess_cmds() would end up waiting indefinately for the last se_cmd->cmd_kref put to occur for the failed SCSI WRITE + ImmediateData descriptors. This fix follows what traditional iscsi-target code already does for the same failure case within iscsit_get_immediate_data(). Reported-by:

commit 8ef42ddd upstream. Not all host controller drivers have bus-suspend and bus-resume methods. When one doesn't, it will cause problems if runtime PM is enabled in the kernel. The PM core will attempt to suspend the controller's root hub, the suspend will fail because there is no bus-suspend routine, and a -EBUSY error code will be returned to the PM core. This will cause the suspend attempt to be repeated shortly thereafter, in a never-ending loop. Part of the problem is that the original error code -ENOENT gets changed to -EBUSY in usb_runtime_suspend(), on the grounds that the PM core will interpret -ENOENT as meaning that the root hub has gotten into a runtime-PM error state. While this change is appropriate for real USB devices, it's not such a good idea for a root hub. In fact, considering the root hub to be in a runtime-PM error state would not be far from the truth. Therefore this patch updates usb_runtime_suspend() so that it adjusts error codes only for non-root-hub devices. Furthermore, the patch attempts to prevent the problem from occurring in the first place by not enabling runtime PM by default for root hubs whose host controller driver doesn't have bus_suspend and bus_resume methods.

commit c03890ff upstream. A recent patch that purported to fix firmware download on big-endian machines failed to add the corresponding sparse annotation to the i2c-header. This was reported by the kbuild test robot. Adding the appropriate annotation revealed another endianess bug related to the i2c-header Size-field in a code path that is exercised when the firmware is actually being downloaded (and not just verified and left untouched unless older than the firmware at hand). This patch adds the required sparse annotation to the i2c-header and makes sure that the Size-field is sent in little-endian byte order during firmware download also on big-endian machines. Note that this patch is only compile-tested, but that there is no functional change for little-endian systems. Reported-by:

commit 5dc2808c upstream. Lists of endpoints are stored for bandwidth calculation for roothub ports. Make sure we remove all endpoints from the list before the whole device, containing its endpoints list_head stuctures, is freed. This used to be done in the wrong order in xhci_mem_cleanup(), and triggered an oops in resume from S4 (hibernate). Tested-by:

commit 2ac295a5 upstream. Commit 8313b8e5 md: fix problem when adding device to read-only array with bitmap. added a called to md_reap_sync_thread() which cause a reshape thread to be interrupted (in particular, it could cause md_thread() to never even call md_do_sync()). However it didn't set MD_RECOVERY_INTR so ->finish_reshape() would not know that the reshape didn't complete. This only happens when mddev->ro is set and normally reshape threads don't run in that situation. But raid5 and raid10 can start a reshape thread during "run" is the array is in the middle of a reshape. They do this even if ->ro is set. So it is best to set MD_RECOVERY_INTR before abortingg the sync thread, just in case. Though it rare for this to trigger a problem it can cause data corruption because the reshape isn't finished properly. So it is suitable for any stable which the offending commit was applied to.
