2013-04-07alpha: irq: run all handlers with interrupts disabledWill Deacon
Linux has expected that interrupt handlers are executed with local interrupts disabled for a while now, so ensure that this is the case on Alpha even for non-device interrupts such as IPIs. Without this patch, secondary boot results in the following backtrace: warning: at kernel/softirq.c:139 __local_bh_enable+0xb8/0xd0() trace: __local_bh_enable+0xb8/0xd0 irq_enter+0x74/0xa0 scheduler_ipi+0x50/0x100 handle_ipi+0x84/0x260 do_entint+0x1ac/0x2e0 irq_exit+0x60/0xa0 handle_irq+0x98/0x100 do_entint+0x2c8/0x2e0 ret_from_sys_call+0x0/0x10 load_balance+0x3e4/0x870 cpu_idle+0x24/0x80 rcu_eqs_enter_common.isra.38+0x0/0x120 cpu_idle+0x40/0x80 rest_init+0xc0/0xe0 _stext+0x1c/0x20 A similar dump occurs if you try to reboot using magic-sysrq.

Due to all of the goodness being packed into today's kernels, the resulting image isn't as slim as it once was. In light of this, don't pass -msmall-data to gcc, which otherwise results in link failures due to impossible relocations when compiling anything but the most trivial configurations.

2013-04-07ipv6/tcp: Stop processing ICMPv6 redirect messagesChristoph Paasch
Tetja Rediske found that if the host receives an ICMPv6 redirect message after sending a SYN+ACK, the connection will be reset. He bisected it down to 093d04d (ipv6: Change skb->data before using icmpv6_notify() to propagate redirect), but the origin of the bug comes from ec18d9a26 (ipv6: Add redirect support to all protocol icmp error handlers.). The bug simply did not trigger prior to 093d04d, because skb->data did not point to the inner IP header and thus icmpv6_notify did not call the correct err_handler. This patch adds the missing "goto out;" in tcp_v6_err. After receiving an ICMPv6 Redirect, we should not continue processing the ICMP in tcp_v6_err, as this may trigger the removal of request-socks or setting sk_err(_soft).

2013-04-06[SCSI] libsas: fix handling vacant phy in sas_set_ex_phy()Lukasz Dorau
If a result of the SMP discover function is PHY VACANT, the content of discover response structure (dr) is not valid. It sometimes happens that dr->attached_sas_addr can contain even SAS address of other phy. In such case an invalid phy is created, what causes NULL pointer dereference during destruction of expander's phys. So if a result of SMP function is PHY VACANT, the content of discover response structure (dr) must not be copied to phy structure. This patch fixes the following bug: BUG: unable to handle kernel NULL pointer dereference at 0000000000000030 IP: [<ffffffff811c9002>] sysfs_find_dirent+0x12/0x90 Call Trace: [<ffffffff811c95f5>] sysfs_get_dirent+0x35/0x80 [<ffffffff811cb55e>] sysfs_unmerge_group+0x1e/0xb0 [<ffffffff813329f4>] dpm_sysfs_remove+0x24/0x90 [<ffffffff8132b0f4>] device_del+0x44/0x1d0 [<ffffffffa016fc59>] sas_rphy_delete+0x9/0x20 [scsi_transport_sas] [<ffffffffa01a16f6>] sas_destruct_devices+0xe6/0x110 [libsas] [<ffffffff8107ac7c>] process_one_work+0x16c/0x350 [<ffffffff8107d84a>] worker_thread+0x17a/0x410 [<ffffffff81081b76>] kthread+0x96/0xa0 [<ffffffff81464944>] kernel_thread_helper+0x4/0x10 Signed-off-by: Lukasz Dorau <lukasz.dorau@intel.com> Signed-off-by: Pawel Baldysiak <pawel.baldysiak@intel.com> Reviewed-by: Maciej Patelczyk <maciej.patelczyk@intel.com> Cc: <stable@vger.kernel.org> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

2013-04-06[SCSI] st: Take additional queue ref in st_probeJoe Lawrence
This patch fixes a reference count bug in the SCSI tape driver which can be reproduced with the following: * Boot with slub_debug=FZPU, tape drive attached * echo 1 > /sys/devices/... tape device pci path .../remove * Wait for device removal * echo 1 > /sys/kernel/slab/blkdev_queue/validate * Slub debug complains about corrupted poison pattern In commit 523e1d39 (block: make gendisk hold a reference to its queue) add_disk() and disk_release() were modified to get/put an additional reference on a disk queue to fix a reference counting discrepency between bdev release and SCSI device removal. The ST driver never calls add_disk(), so this commit introduced an extra kref put when the ST driver frees its struct gendisk. Attempts were made to fix this bug at the block level [1] but later abandoned due to floppy driver issues [2].

At the same time, remove a pointless flags override line - the variable assigned to was misspelled anyway, and the options added are meaningless for assembly sources.

Use of list_for_each_entry() is therefore the correct thing to do. Also fix the refcounting in nfs41_walk_client_list().

2013-04-05netfilter: don't reset nf_trace in nf_reset()Patrick McHardy
Commit 130549fe ("netfilter: reset nf_trace in nf_reset") added code to reset nf_trace in nf_reset(). This is wrong and unnecessary. nf_reset() is used in the following cases: - when passing packets up the the socket layer, at which point we want to release all netfilter references that might keep modules pinned while the packet is queued. nf_trace doesn't matter anymore at this point. - when encapsulating or decapsulating IPsec packets. We want to continue tracing these packets after IPsec processing. - when passing packets through virtual network devices. Only devices on that encapsulate in IPv4/v6 matter since otherwise nf_trace is not used anymore. Its not entirely clear whether those packets should be traced after that, however we've always done that. - when passing packets through virtual network devices that make the packet cross network namespace boundaries. This is the only cases where we clearly want to reset nf_trace and is also what the original patch intended to fix. Add a new function nf_reset_trace() and use it in dev_forward_skb() to fix this properly. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-04-05GFS2: Issue discards in 512b sectorsBob Peterson
This patch changes GFS2's discard issuing code so that it calls function sb_issue_discard rather than blkdev_issue_discard. The code was calling blkdev_issue_discard and specifying the correct sector offset and sector size, but blkdev_issue_discard expects these values to be in terms of 512 byte sectors, even if the native sector size for the device is different. Calling sb_issue_discard with the BLOCK size instead ensures the correct block-to-512b-sector translation. I verified that "minlen" is specified in blocks, so comparing it to a number of blocks is correct.

2013-04-05Revert "drivers/rtc/rtc-at91rm9200.c: use a variable for storing IMR"Johan Hovold
This reverts commit 0ef1594c017521ea89278e80fe3f80dafb17abde. This patch introduced a few races which cannot be easily fixed with a small follow-up patch. Furthermore, the SoC with the broken hardware register, which this patch intended to add support for, can only be used with device trees, which this driver currently does not support.

Even in failed case of pm_runtime_get_sync, the usage_count is incremented. In order to keep the usage_count with correct value and runtime power management to behave correctly, call pm_runtime_put_noidle in such case. In __hwspin_lock_request, module_put is also called before return in pm_runtime_get_sync failed case.

2013-04-05dm cache: reduce bio front_pad size in writeback modeMike Snitzer
A recent patch to fix the dm cache target's writethrough mode extended the bio's front_pad to include a 1056-byte struct dm_bio_details. Writeback mode doesn't need this, so this patch reduces the per_bio_data_size to 16 bytes in this case instead of 1096. The dm_bio_details structure was added in "dm cache: fix writes to cache device in writethrough mode" which fixed commit e2e74d617e ("dm cache: fix race in writethrough implementation"). In writeback mode we avoid allocating the writethrough-specific members of the per_bio_data structure (the dm_bio_details structure included).

2013-04-05dm cache: fix writes to cache device in writethrough modeDarrick J. Wong
The dm-cache writethrough strategy introduced by commit e2e74d617eadc15 ("dm cache: fix race in writethrough implementation") issues a bio to the origin device, remaps and then issues the bio to the cache device. This more conservative in-series approach was selected to favor correctness over performance (of the previous parallel writethrough). However, this in-series implementation that reuses the same bio to write both the origin and cache device didn't take into account that the block layer's req_bio_endio() modifies a completing bio's bi_sector and bi_size. So the new writethrough strategy needs to preserve these bio fields, and restore them before submission to the cache device, otherwise nothing gets written to the cache (because bi_size is 0). This patch adds a struct dm_bio_details field to struct per_bio_data, and uses dm_bio_record() and dm_bio_restore() to ensure the bio is restored before reissuing to the cache device. Adding such a large structure to the per_bio_data is not ideal but we can improve this later, for now correctness is the important thing. This problem initially went unnoticed because the dm-cache test-suite uses a linear DM device for the dm-cache device's origin device. Writethrough worked as expected because DM submits a *clone* of the original bio, so the original bio which was reused for the cache was never touched. Signed-off-by: Darrick J.

2013-04-05MIPS: Delete definition of SA_RESTORER.Ralf Baechle
SA_RESTORER used to be defined as 0x04000000 but only the O32 ABI ever supported its use and no libc was using it, so the entire sa-restorer functionality was removed with lmo commit 39bffc12c3580ab [Zap sa_restorer.] for 2.5.48 retaining only the SA_RESTORER definition as a reminder to avoid accidental reuse of the mask bit. Upstream cdef9602fbf1871a43f0f1b5cea10dd0f275167d [signal: always clear sa_restorer on execve] adds code that assumes sa_sigaction has an sa_restorer field, if SA_RESTORER is defined which would break MIPS. So remove the SA_RESTORER definition before the v3.8.4 merge. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> (cherry picked from commit 17da8d63add23830892ac4dc2cbb3b5d4ffb79a8)
2013-04-05MIPS: Fix ISA level which causes secondary cache init bypassing and moreDeng-Cheng Zhu
The commit a96102be70 introduced set_isa() where compatible ISA info is also set aside from the one gets passed in. It means, for example, 1004K will have MIPS_CPU_ISA_M32R2/M32R1/II/I flags. This leads to things like the following inappropriate: if (c->isa_level == MIPS_CPU_ISA_M32R1 || c->isa_level == MIPS_CPU_ISA_M32R2 || c->isa_level == MIPS_CPU_ISA_M64R1 || c->isa_level == MIPS_CPU_ISA_M64R2) This patch fixes it.

This adds the missing comma. This was not noticed until now because the crypto block is not in the ux500 defconfig. A separate patch will be submitted to fix this.
