798cb7e Takashi Iwai 30 September 2011, 06:52:26 UTC ALSA: hda - Fix a regression of the position-buffer check The commit a810364a0424c297242c6c66071a42f7675a5568 ALSA: hda - Handle -1 as invalid position, too caused a regression on some machines that require the position-buffer instead of LPIB, e.g. resulting in noises with mic recording with PulseAudio. This patch fixes the detection by delaying the test at the timing as same as 3.0, i.e. doing the position check only when requested in azx_position_ok().

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. I believe this bug has been there for ages. It got exposed by git commit 2bbc6942273b ("PCI : ability to relocate assigned pci-resources") Signed-off-by: Ram Pai <linuxram@us.ibm.com> Tested-by: Michal Ludvig <mludvig@logix.net.nz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 30 September 2011, 03:04:34 UTC

This breaks graphics on those machines among others. This fixes it using a quirk which copies the node pointer from the host bridge for the root complex, which makes the generic code work for the children afterward.

b0f8437 wangyanqing 29 September 2011, 07:09:40 UTC bootup: move 'usermodehelper_enable()' a little earlier Commit d5767c53535a ("bootup: move 'usermodehelper_enable()' to the end of do_basic_setup()") moved 'usermodehelper_enable()' to end of do_basic_setup() to after the initcalls. But then I get failed to let uvesafb work on my computer, and lose the splash boot. 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().. So I'm just using wang yanqing's trivial patch. It's not wonderful, but it's simple and should work. We should revisit this some day, though. - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 30 September 2011, 02:21:01 UTC

This ends up with invalid event and perf record being stuck in __perf_session__process_events function during processing build IDs (process_buildids function).

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). The old code was written as if the updates were a complete enumeration; that was just wrong. Update the code to remove 0-length entries and drop the rbtree traversal. This avoids misdirected (and hung) requests that manifest as server errors like [WRN] client4104 10.0.1.219:0/275025290 misdirected client4104.1:129 0.1 to osd0 not [1,0] in e11/11 Signed-off-by: Sage Weil <sage@newdream.net> 28 September 2011, 17:13:35 UTC

When icmp packets with wrong checksum pass through the octeon net driver, the not_IP, IP_exc, L4_error hardware indicators show no error. so the driver sets CHECKSUM_UNNECESSARY on skb->ip_summed.

b6c8069 Linus Torvalds 27 September 2011, 15:12:33 UTC vfs: remove LOOKUP_NO_AUTOMOUNT flag That flag no longer makes sense, since we don't look up automount points as eagerly any more. Additionally, it turns out that the NO_AUTOMOUNT handling was buggy to begin with: it would avoid automounting even for cases where we really *needed* to do the automount handling, and could return ENOENT for autofs entries that hadn't been instantiated yet. With our new non-eager automount semantics, one discussion has been about adding a AT_AUTOMOUNT flag to vfs_fstatat (and thus the newfstatat() and fstatat64() system calls), but it's probably not worth it: you can always force at least directory automounting by simply adding the final '/' to the filename, which works for *all* of the stat family system calls, old and new. So AT_NO_AUTOMOUNT (and thus LOOKUP_NO_AUTOMOUNT) really were just a result of our bad default behavior.

815d405 Trond Myklebust 27 September 2011, 00:36:09 UTC VFS: Fix the remaining automounter semantics regressions The concensus seems to be that system calls such as stat() etc should not trigger an automount. Neither should the l* versions. This patch therefore adds a LOOKUP_AUTOMOUNT flag to tag those lookups that _should_ trigger an automount on the last path element. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> [ Edited to leave out the cases that are already covered by LOOKUP_OPEN, LOOKUP_DIRECTORY and LOOKUP_CREATE - all of which also fundamentally force automounting for their own reasons - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 27 September 2011, 02:16:46 UTC
d94c177 Linus Torvalds 27 September 2011, 00:44:55 UTC vfs pathname lookup: Add LOOKUP_AUTOMOUNT flag Since we've now turned around and made LOOKUP_FOLLOW *not* force an automount, we want to add the ability to force an automount event on lookup even if we don't happen to have one of the other flags that force it implicitly (LOOKUP_OPEN, LOOKUP_DIRECTORY, LOOKUP_PARENT..) Most cases will never want to use this, since you'd normally want to delay automounting as long as possible, which usually implies LOOKUP_OPEN (when we open a file or directory, we really cannot avoid the automount any more). But Trond argued sufficiently forcefully that at a minimum bind mounting a file and quotactl will want to force the automount lookup. Some other cases (like nfs_follow_remote_path()) could use it too, although LOOKUP_DIRECTORY would work there as well. This commit just adds the flag and logic, no users yet, though. It also doesn't actually touch the LOOKUP_NO_AUTOMOUNT flag that is related, and was made irrelevant by the same change that made us not follow on LOOKUP_FOLLOW.

This can lead to a crash later when iwl_bg_scan_completed() tries to run a pending scan request. In practice, this seems to be very rare due to the STATUS_SCANNING check earlier. That check, however, is wrong -- it should allow a scan to be queued when a reset/roc scan is going on. When a normal scan is already going on, a new one can't be issued by mac80211, so that code can be removed completely.

e8b364b Rafael J. Wysocki 26 September 2011, 17:40:23 UTC PM / Clocks: Do not acquire a mutex under a spinlock Commit b7ab83e (PM: Use spinlock instead of mutex in clock management functions) introduced a regression causing clocks_mutex to be acquired under a spinlock. This happens because pm_clk_suspend() and pm_clk_resume() call pm_clk_acquire() under pcd->lock, but pm_clk_acquire() executes clk_get() which causes clocks_mutex to be acquired. Similarly, __pm_clk_remove(), executed under pcd->lock, calls clk_put(), which also causes clocks_mutex to be acquired. To fix those problems make pm_clk_add() call pm_clk_acquire(), so that pm_clk_suspend() and pm_clk_resume() don't have to do that. Change pm_clk_remove() and pm_clk_destroy() to separate modifications of the pcd->clock_list list from the actual removal of PM clock entry objects done by __pm_clk_remove().

The result is the oops above, when t3_l2t_get attempts to dereference L2DATA(cdev)->nentries in arp_hash right after the EEH error handler sets it to NULL. The fix is to prevent the setting of the NULL pointer until after there are no further users of it. The t3cdev->l2opt pointer is now converted to be an rcu pointer and the L2DATA macro is now called under the protection of the rcu_read_lock(). When the EEH error path: t3_adapter_error->offload_close->cxgb3_offload_deactivate Is exectured, setting of that l2opt pointer to NULL, is now gated on an rcu quiescence point, preventing, allowing L2DATA callers to safely check for a NULL pointer without concern that the underlying data will be freeded before the pointer is dereferenced.

For the read path, discarded blocks are handled the same as normal ciphertext blocks, thus decrypted. So if the underlying device announces discarded regions return zeroes, dm-crypt must disable this flag because after decryption there is just random noise instead of zeroes.

876fbba Mike Snitzer 25 September 2011, 22:26:17 UTC dm table: avoid crash if integrity profile changes Commit a63a5cf (dm: improve block integrity support) introduced a two-phase initialization of a DM device's integrity profile. This patch avoids dereferencing a NULL 'template_disk' pointer in blk_integrity_register() if there is an integrity profile mismatch in dm_table_set_integrity(). This can occur if the integrity profiles for stacked devices in a DM table are changed between the call to dm_table_prealloc_integrity() and dm_table_set_integrity().

WERROR=0 allows one to build perf without much fuss - while still encouraging people to send patches to avoid the fuss of having to type WERROR=0. Bisecting back to commits that produce a (mostly harmless) warning on some compilers is more difficult. With WERROR=0 one could bisect without worrying about harmless warnings.

be96ea8 Stephane Eranian 22 October 2010, 15:25:01 UTC perf symbols: Fix issue with binaries using 16-bytes buildids (v2) Buildid can vary in size. According to the man page of ld, buildid can be 160 bits (sha1) or 128 bits (md5, uuid). Perf assumes buildid size of 20 bytes (160 bits) regardless. When dealing with md5 buildids, it would thus read more than needed and that would cause mismatches and samples without symbols. This patch fixes this by taking into account the actual buildid size as encoded int he section header. The leftover bytes are also cleared. This second version fixes a minor issue with the memset() base position. Cc: David S.

936be50 David Ahern 06 September 2011, 15:12:26 UTC perf tool: Fix endianness handling of u32 data in samples Currently, analyzing PPC data files on x86 the cpu field is always 0 and the tid and pid are backwards. For example, analyzing a PPC file on PPC the pid/tid fields show: rsyslogd 1210/1212 and analyzing the same PPC file using an x86 perf binary shows: rsyslogd 1212/1210 The problem is that the swap_op method for samples is perf_event__all64_swap which assumes all elements in the sample_data struct are u64s. cpu, tid and pid are u32s and need to be handled individually. Given that the swap is done before the sample is parsed, the simplest solution is to undo the 64-bit swap of those elements when the sample is parsed and do the proper swap. The RAW data field is generic and perf cannot have programmatic knowledge of how to treat that data. Instead a warning is given to the user. Thanks to Anton Blanchard for providing a data file for a mult-CPU PPC system so I could verify the fix for the CPU fields. v3 -> v4: - fixed use of WARN_ONCE v2 -> v3: - used WARN_ONCE for message regarding raw data - removed struct wrapper around union - fixed whitespace issues v1 -> v2: - added a union for undoing the byte-swap on u64 and redoing swap on u32's to address compiler errors (see git commit 65014ab3) Cc: Anton Blanchard <anton@samba.org> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Link: http://lkml.kernel.org/r/1315321946-16993-1-git-send-email-dsahern@gmail.com Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> 23 September 2011, 17:37:27 UTC
6bb8f31 Anton Blanchard 31 August 2011, 01:51:45 UTC perf sort: Fix symbol sort output by separating unresolved samples by type I took a profile that suggested 60% of total CPU time was in the hypervisor: ... 60.20% [H] 0x33d43c 4.43% [k] ._spin_lock_irqsave 1.07% [k] ._spin_lock Using perf stat to get the user/kernel/hypervisor breakdown contradicted this. The problem is we merge all unresolved samples into the one unknown bucket. If add a comparison by sample type to sort__sym_cmp we get the real picture: ... 57.11% [.] 0x80fbf63c 4.43% [k] ._spin_lock_irqsave 1.07% [k] ._spin_lock 0.65% [H] 0x33d43c So it was almost all userspace, not hypervisor as the initial profile suggested. I found another issue while adding this. Symbol sorting sometimes shows multiple entries for the unknown bucket: ... 16.65% [.] 0x6cd3a8 7.25% [.] 0x422460 5.37% [.] yylex 4.79% [.] malloc 4.78% [.] _int_malloc 4.03% [.] _int_free 3.95% [.] hash_source_code_string 2.82% [.] 0x532908 2.64% [.] 0x36b538 0.94% [H] 0x8000000000e132a4 0.82% [H] 0x800000000000e8b0 This happens because we aren't consistent with our sorting. On one hand we check to see if both symbols match and for two unresolved samples sym is NULL so we match: if (left->ms.sym == right->ms.sym) return 0; On the other hand we use sample IP for unresolved samples when comparing against a symbol: ip_l = left->ms.sym ? left->ms.sym->start : left->ip; ip_r = right->ms.sym ? right->ms.sym->start : right->ip; This means unresolved samples end up spread across the rbtree and we can't merge them all. If we use cmp_null all unresolved samples will end up in the one bucket and the output makes more sense: ... 39.12% [.] 0x36b538 5.37% [.] yylex 4.79% [.] malloc 4.78% [.] _int_malloc 4.03% [.] _int_free 3.95% [.] hash_source_code_string 2.26% [H] 0x800000000000e8b0 Acked-by: Eric B Munson <emunson@mgebm.net> Cc: Eric B Munson <emunson@mgebm.net> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Ian Munsie <imunsie@au1.ibm.com> Link: http://lkml.kernel.org/r/20110831115145.4f598ab2@kryten Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> 23 September 2011, 17:37:17 UTC
