Sometime it is seen that controller firmware returns an invalid system message id (smid). the oops is occurring becuase mpt_callbacks pointer is referenced to either null or invalid virtual address. this is due to cb_idx set incorrectly from routine _base_get_cb_idx. the cb_idx was set incorrectly becuase there is no check to make sure smid is less than maxiumum anticapted smid. to fix this issue, we add a check in _base_get_cb_idx to make sure smid is not greater than ioc->hba_queue_depth. in addition, a similar check was added to make sure the reply address was less than the largest anticapated address. Newer firmware has sovled this issue, however it good to have this sanity check. Signed-off-by:

Add SLI4 FC Discovery support - Replace READ_LA and READ_LA64 with READ_TOPOLOGY mailbox command. - Converted the old READ_LA structure to use bf_set/get instead of bit fields. - Rename HBA_FCOE_SUPPORT flag to HBA_FCOE_MODE. Flag now indicates function is running as SLI-4 FC or FCoE port. Make sure flag reset each time READ_REV completed as it can dynamically change. - Removed BDE union in the READ_TOPOLOGY mailbox command and added a define to define the ALPA MAP SIZE. Added FC Code for async events. - Added code to support new 16G link speed. - Define new set of values to keep track of valid user settable link speeds. - Used new link speed definitions to define link speed max and bitmap. - Redefined FDMI Port sppeds to be hax values and added the 16G value. - Added new CQE trailer code for FC Events. - Add lpfc_issue_init_vfi and lpfc_init_vfi_cmpl routines. - Replace many calls to the initial_flogi routine with lpfc_issue_init_vfi. - Add vp and vpi fields to the INIT_VFI mailbox command. - Addapt lpfc_hba_init_link routine for SLI4 use. - Use lpfc_hba_init_link call from lpfc_sli4_hba_setup. - Add a check for FC mode to register the FCFI before init link. - Convert lpfc_sli4_init_vpi to be called without a vpi (get it from vport).

The current code in scsi_eh_target_reset() has an off by one error that actually sends spurious extra resets. Since there's no real need to reset the targets in numerical order, simply chunk up the command recovery list doing target resets and pulling matching targets out of the list (that also makes the loop O(N) instead of O(N^2).

The lun value was not getting set up correctly for all devices attached to the new 64 bit adapters. The fix is to move the logic to earlier in the ipr_init_res_entry routine such that the value does get set correctly for all devices. Then the ipr_is_same_device comparison function was using the wrong lun value in the logic for the new adapters. Change this to use the correct lun value. Signed-off-by:

Some kernel transport drivers unconditionally disable retrieval of the Caching mode page. One such for example is the BBB/CBI transport over USB. Such a restraint is too harsh as some devices do support the Caching mode page. Unconditionally enabling the retrieval of this mode page over those transports at their transport code level may result in some devices failing and becoming unusable. This patch implements a method of retrieving the Caching mode page without unconditionally enabling it in the transports which unconditionally disable it. The idea is to ask for all supported pages, page code 0x3F, and then search for the Caching mode page in the mode parameter data returned. The sd driver already asks for all the mode pages supported by the attached device by setting the page code to 0x3F in order to find out if the media is write protected by reading the WP bit in the Device Specific Parameter field. It then attempts to retrieve only the Caching mode page by setting the page code to 8 and actually attempting to retrieve it if and only if the transport allows it. The method implemented here is that if the transport doesn't allow retrieval of the Caching mode page and the device is not RBC, then we ask for all pages supported by setting the page code to 0x3F (similarly to how the WP bit is retrieved above), and then we search for the Caching mode page in the mode parameter data returned. With this patch, devices over SATA, report this (no change): Oct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] 976773168 512-byte logical blocks: (500 GB/465 GiB) Oct 22 18:45:58 localhost kernel: sd 0:0:0:0: Attached scsi generic sg0 type 0 Oct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] Write Protect is off Oct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 Oct 22 18:45:58 localhost kernel: sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Smart devices report their Caching mode page.

To date libsas has only looked at the attached sas address when determining the formation of wide ports. The specification and some hardware expects that phys with different addresses will not form a wide port unless the local peer phys also match each other. Introduce a flag to select stricter behavior at sas_register_ha() time. The flag can be dropped once it is known that all libsas users expect the same behavior. Current drivers just initialize this field to zero and get the traditional behavior. Reported-by:

This patch (as1415) improves the formerly incomprehensible logic in sd_media_changed() (the current code refers to "changed" as a state, whereas in fact it is a relation between two states). It also adds a big comment so that everyone can understand what is really going on. The patch also improves efficiency by not reporting a media change when no medium was ever present. If no medium was present the last time we checked and there's still no medium, it's not necessary to tell the caller that a change occurred. Doing so merely causes the caller to attempt to revalidate a non-existent disk, which is a waste of time. Signed-off-by:

The install_special_mapping routine (used, for example, to setup the vdso) skips the security check before insert_vm_struct, allowing a local attacker to bypass the mmap_min_addr security restriction by limiting the available pages for special mappings. bprm_mm_init() also skips the check, and although I don't think this can be used to bypass any restrictions, I don't see any reason not to have the security check. $ uname -m x86_64 $ cat /proc/sys/vm/mmap_min_addr 65536 $ cat install_special_mapping.s section .bss resb BSS_SIZE section .text global _start _start: mov eax, __NR_pause int 0x80 $ nasm -D__NR_pause=29 -DBSS_SIZE=0xfffed000 -f elf -o install_special_mapping.o install_special_mapping.s $ ld -m elf_i386 -Ttext=0x10000 -Tbss=0x11000 -o install_special_mapping install_special_mapping.o $ ./install_special_mapping & [1] 14303 $ cat /proc/14303/maps 0000f000-00010000 r-xp 00000000 00:00 0 [vdso] 00010000-00011000 r-xp 00001000 00:19 2453665 /home/taviso/install_special_mapping 00011000-ffffe000 rwxp 00000000 00:00 0 [stack] It's worth noting that Red Hat are shipping with mmap_min_addr set to 4096.

Cache ownership must be acquired by reading/writing data from the cache line to make cache operation have the desired effect on the SMP MPCore CPU. However, the ownership is never acquired in the v6_dma_inv_range function when cleaning the first line and flushing the last one, in case the address is not aligned to D_CACHE_LINE_SIZE boundary. Fix this by reading/writing data if needed, before performing cache operations. While at it, fix v6_dma_flush_range to prevent RWFO outside the buffer. Cc: stable@kernel.org Signed-off-by:

Because the nwfpe support is unlikely to be used on new platforms and requires CONFIG_OABI_COMPAT, which is not generally used with ARMv7+, we shouldn't expect to build nwfpe support into a Thumb-2 kernel. At present, nwfpe contains assembly code which isn't Thumb-2 compatible, and for now it doesn't appear useful to port this code. All ARMv7-A/R platforms necessarily have VFPv3 hardware floating- point natively, making emulation unnecessary. Signed-off-by:

This makes sense, because Thumb-2 code can't execute on plain ARMv6 processors. This will avoid accidentally configuring a broken kernel where the config otherwise would allow multiple architecture versions to coexist in the same kernel. Not adding !CPU_V5 etc., because the chance of anyone trying to put v5 and v7 in the same kernel is low, and I'm not aware of any mach which can do this. These could be added later if it matters. Note that the rules may need to be refined if support for the ARM1156J(F)-S processor is later added to the kernel, since this processor supports the rare ARMv6T2 extensions, which add support for Thumb-2 and a few other ARMv7 features.
