* mptfusion: prevent some memory corruptionDan Carpenter2015-08-261-0/+9
| | | | | | | | | | | | | These are signed values the come from the user, we put a cap on the upper bounds but not on the lower bounds. We use "karg.dataSgeOffset" to calculate "sz". We verify "sz" and proceed as if that means that "karg.dataSgeOffset" is correct but this fails to consider that the "sz" calculations can have integer overflows.

* qla2xxx: prevent board_disable from running during EEHThadeu Lima de Souza Cascardo2015-08-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f3ddac1918fe963bcbf8d407a3a3c0881b47248b ("[SCSI] qla2xxx: Disable adapter when we encounter a PCI disconnect.") has introduced a code that disables the board, releasing some resources, when reading 0xffffffff. In case this happens when there is an EEH, this read will trigger EEH detection and set PCI channel offline. EEH will be able to recover the card from this state by doing a reset, so it's a better option than simply disabling the card. Since eeh_check_failure will mark the channel as offline before returning the read value, in case there really was an EEH, we can simply check for pci_channel_offline, preventing the board_disable code from running if it's true. Without this patch, EEH code will try to access those same resources that board_disable will try to free. This race can cause EEH recovery to fail.

* iSCSI: let session recovery_tmo sysfs writes persist across recoveryChris Leech2015-07-301-3/+8
| | | | | | | | | | | | | | | | | | | | | | | The iSCSI session recovery_tmo setting is writeable in sysfs, but it's also set every time a connection is established when parameters are set from iscsid over netlink. That results in the timeout being reset to the default value after every recovery. The DM multipath tools want to use the sysfs interface to lower the default timeout when there are multiple paths to fail over. It has caused confusion that we have a writeable sysfs value that seem to keep resetting itself. This patch adds an in-kernel flag that gets set once a sysfs write occurs, and then ignores netlink parameter setting once it's been modified via the sysfs interface. My thinking here is that the sysfs interface is much simpler for external tools to influence the session timeout, but if we're going to allow it to be modified directly we should ensure that setting is maintained.

* scsi: fix memory leak with scsi-mqTony Battersby2015-07-302-4/+4
| | | | | | | | | | | | | | | | | | | | Fix a memory leak with scsi-mq triggered by commands with large data transfer length. __sg_alloc_table() sets both table->nents and table->orig_nents to the same value. When the scatterlist is DMA-mapped, table->nents is overwritten with the (possibly smaller) size of the DMA-mapped scatterlist, while table->orig_nents retains the original size of the allocated scatterlist. scsi_free_sgtable() should therefore check orig_nents instead of nents, and all code that initializes sdb->table without calling __sg_alloc_table() should set both nents and orig_nents.

* ipr: Fix invalid array indexing for HRRQBrian King2015-07-301-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes another signed / unsigned array indexing bug in the ipr driver. Currently, when hrrq_index wraps, it becomes a negative number. We do the modulo, but still have a negative number, so we end up indexing backwards in the array. Given where the hrrq array is located in memory, we probably won't actually reference memory we don't own, but nonetheless ipr is still looking at data within struct ipr_ioa_cfg and interpreting it as struct ipr_hrr_queue data, so bad things could certainly happen. Each ipr adapter has anywhere from 1 to 16 HRRQs. By default, we use 2 on new adapters. Let's take an example: Assume ioa_cfg->hrrq_index=0x7fffffffe and ioa_cfg->hrrq_num=4: The atomic_add_return will then return -1. We mod this with 3 and get -2, add one and get -1 for an array index. On adapters which support more than a single HRRQ, we dedicate HRRQ to adapter initialization and error interrupts so that we can optimize the other queues for fast path I/O. So all normal I/O uses HRRQ 1-15. So we want to spread the I/O requests across those HRRQs. With the default module parameter settings, this bug won't hit, only when someone sets the ipr.number_of_msix parameter to a value larger than 3 is when bad things start to happen.

* Revert "drm/i915: Use crtc_state->active in primary check_plane func"Linus Torvalds2015-07-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit dec4f799d0a4c9edae20512fa60b0a36f3299ca2. Jörg Otte reports a NULL pointder dereference due to this commit, as 'crtc_state' very much can be NULL: crtc_state = state->base.state ? intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL; So the change to test 'crtc_state->base.active' cannot possibly be correct as-is. There may be some other minimal fix (like just checking crtc_state for NULL), but I'm just reverting it now for the rc2 release, and people like Daniel Vetter who actually know this code will figure out what the right solution is in the longer term.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wider testing reveals that the Fast Debug Channel (FDC) interrupt is routed through the GIC just fine on Pistachio SoC, even though it contains interAptiv cores. Clearly the FDC interrupt routing problems previously observed on interAptiv and proAptiv cores are specific to the Malta FPGA bitstreams. Move the workaround for interAptiv and proAptiv out of gic_get_c0_fdc_int() in the GIC irqchip driver into Malta's get_c0_fdc_int() platform callback, to allow the Pistachio SoC to use the FDC interrupt.
