* ARM: make entry-macro.S depend on !MULTI_IRQ_HANDLERRob Herring2012-02-221-1/+2
| | | | | | | | | | With the removal of disable_fiq on rpc and addition MULTI_IRQ_HANDLER, entry-macro.S is no longer needed for platforms that select MULTI_IRQ_HANDLER and the include of it can be conditional.

* ARM: rpc: make default fiq handler run-time installedRob Herring2012-02-223-1/+23
| | | | | | | | | Only rpc uses disable_fiq macro. Change it to a run-time installed default FIQ handler. The handler is installed before FIQ is enabled so the behavior should be unchanged. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Nicolas Pitre <nico@linaro.org>

| * iommu/msm: Fix error handling in msm_iommu_unmap()Joerg Roedel2012-01-301-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Error handling in msm_iommu_unmap() is broken. On some error conditions retval is set to a non-zero value which causes the function to return 'len' at the end. This hides the error from the user. Zero should be returned in those error cases.

| * iommu/amd: Work around broken IVRS tablesJoerg Roedel2012-01-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | On some systems the IVRS table does not contain all PCI devices present in the system. In case a device not present in the IVRS table is translated by the IOMMU no DMA is possible from that device by default. This patch fixes this by removing the DTE entry for every PCI device present in the system and not covered by IVRS.

| * | target: Fix unsupported WRITE_SAME sense payloadMartin Svec2012-02-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a bug in target-core where unsupported WRITE_SAME ops from a target_check_write_same_discard() failure was incorrectly returning CHECK_CONDITION w/ TCM_INVALID_CDB_FIELD sense data. This was causing some clients to not properly fall back, so go ahead and use the correct TCM_UNSUPPORTED_SCSI_OPCODE sense for this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use IP_FREEBIND socket option so that iscsi portal configuration with explicit IP addresses can happen during boot, before network interfaces have been assigned IPs. This is especially important on systemd based Linux boxes where system boot happens asynchronously and non-trivial configuration must be done to get targetcli.service to start synchronously after the network is configured.

For transport_generic_allocate_tasks() failures, use the proper call to transport_generic_request_failure() to handle kref_put() along with potential internal queue full response processing. It also makes transport_lookup_cmd_lun() failures in target_submit_cmd() use transport_send_check_condition_and_sense() and target_put_sess_cmd() directly to avoid se_cmd->se_dev reference in transport_generic_request_failure() handling. Finally it drops the out_check_cond: label and use direct reference for allocate task failures, and per-se_device queue_full handling is currently not supported for transport_lookup_cmd_lun() failure descriptors due to se_device dependency.

Once submitted, fabrics should expect a sense error if anything goes wrong. All fabrics checking of this retval are useless or broken: fc checks it just to emit more debug output. ib_srpt trickles retval up, then it is ignored. qla2xxx trickles it up, which then causes a bug because the abort goto in qla_target.c thinks cmd hasn't been sent to target.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | WindowsXP+BOT issues a MODE_SENSE request with page 0x1c which is not suppoerted by target. Target rejects that command with TCM_INVALID_CDB_FIELD, so far so good. On BOT I can't send the SENSE response back, instead I can only reply that an error occured. The next thing happens is a REQUEST_SENSE request with 18 bytes length. Since the check here is more than 18 bytes I have to NACK that request as well. This is not really required: We check for some additional room, but we never use it. The additional length is set to 0xa so the total length is 0xa + 8 = 18 which is fine with my 18 bytes.

Without this patch, a tcm_loop LUN incorrectly gives: # sg_raw -r 1 -v /dev/sda 3 1 0 0 ff 0 Sense Information: Fixed format, current; Sense key: Aborted Command Additional sense: Invalid field in cdb Raw sense data (in hex): 70 00 0b 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 While a real SCSI disk gives: Sense Information: Fixed format, current; Sense key: Illegal Request Additional sense: Invalid field in cdb Raw sense data (in hex): 70 00 05 00 00 00 00 18 00 00 00 00 24 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 with the main point being that the real disk gives a sense key of ILLEGAL REQUEST (5h).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Doing alloc_page(GFP_KERNEL | __GFP_ZERO) to get pages used for data buffers wastes a lot of CPU clearing pages that will be quickly be overwritten by the actual data. However, for emulated control commands such as INQUIRY and so on, the code does assume that the buffer is zeroed. To avoid this CPU overhead, skip the __GFP_ZERO for commands that are actually moving data, ie cmds that have SCF_SCSI_DATA_SG_IO_CDB set.

If steps 2 & 3 above are repeated, bitmap_load is called multiple times. It is only written to be called once; otherwise, it allocates new memory for the bitmap (without freeing the old) and incrementing the number of pages it thinks it has without zeroing first. This ultimately leads to access beyond allocated memory and lost memory. Simply avoiding the bitmap_load call upon resume is not sufficient. If the target was suspended while the initial recovery was only partially complete, it needs to be restarted when the target is resumed. This is why 'md_wakeup_thread' is called before issuing the 'mddev_resume'. Signed-off-by: Jonathan Brassow <jbrassow@redhat.com> Signed-off-by: NeilBrown <neilb@suse.de>

A fatal oops quickly follows this warning - often even just a 'dmesg' following the warning causes the kernel to oops. While testing suspend/resume on an ARM device with PCMCIA support, and a CF card inserted, I found that after five suspend and resumes, the kernel would complain, and shortly die after with slab corruption.

Migration avoids entering a new zone by never going beyond the free scanned. Unfortunately, in very rare cases nodes can overlap. When this happens, migration isolates pages without the LRU lock held, corrupting lists which will trigger errors in reclaim or during page free such as in the following oops BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 IP: [<ffffffff810f795c>] free_pcppages_bulk+0xcc/0x450 PGD 1dda554067 PUD 1e1cb58067 PMD 0 Oops: 0000 [#1] SMP CPU 37 Pid: 17088, comm: memcg_process_s Tainted: G X RIP: free_pcppages_bulk+0xcc/0x450 Process memcg_process_s (pid: 17088, threadinfo ffff881c2926e000, task ffff881c2926c0c0) Call Trace: free_hot_cold_page+0x17e/0x1f0 __pagevec_free+0x90/0xb0 release_pages+0x22a/0x260 pagevec_lru_move_fn+0xf3/0x110 putback_lru_page+0x66/0xe0 unmap_and_move+0x156/0x180 migrate_pages+0x9e/0x1b0 compact_zone+0x1f3/0x2f0 compact_zone_order+0xa2/0xe0 try_to_compact_pages+0xdf/0x110 __alloc_pages_direct_compact+0xee/0x1c0 __alloc_pages_slowpath+0x370/0x830 __alloc_pages_nodemask+0x1b1/0x1c0 alloc_pages_vma+0x9b/0x160 do_huge_pmd_anonymous_page+0x160/0x270 do_page_fault+0x207/0x4c0 page_fault+0x25/0x30 The "X" in the taint flag means that external modules were loaded but but is unrelated to the bug triggering.

Limit its value and avoid overflowing nsegs * sizeof(__u64) in the subsequent call to memdup_user(). This patch complements 481fe17e973fb9 ("nilfs2: potential integer overflow in nilfs_ioctl_clean_segments()").

They collide with some -next work so I'd really like to get them into 3.3-rc3 if possible to merge back up into the -next code. All driver specific and unexciting in the grand scheme of things.
