2017-07-25drm/radeon: Set depth on low mem to 16 bpp instead of 8 bppEgbert Eich
The radeon driver reduces the framebuffer resolution to 8bpp if a device with less than 32MB VRAM is found. This causes the framebuffer to run in 8 bit paletted mode. For a text console this is not an issue as 256 different colors is more than one gets on a VGA text console. However this leads to a poor 8bit pseudo-color visual when running X on fbdev, too, which is quite ugly. In this patch, we try to give some moderate compromise: limit the framebuffer bpp to 8 only when VRAM is 8MB or less, and use 16 bpp otherwise for 32MB or less VRAM.

2017-07-25nbd: clear disconnected on reconnectJosef Bacik
If our device loses its connection for longer than the dead timeout we will set NBD_DISCONNECTED in order to quickly fail any pending IO's that flood in after the IO's that were waiting during the dead timer. However if we re-connect at some point in the future we'll still see this DISCONNECTED flag set if we then lose our connection again after that, which means we won't get notifications for our newly lost connections. Fix this by just clearing the DISCONNECTED flag on reconnect in order to make sure everything works as it's supposed to.

2017-07-25dm raid: fix activation check in validate_raid_redundancy()Heinz Mauelshagen
During growing reshapes (i.e. stripes being added to a raid set), the new stripe images are not in-sync and not part of the raid set until the reshape is started. LVM2 has to request multiple table reloads involving superblock updates in order to reflect proper size of SubLVs in the cluster. Before a stripe adding reshape starts, validate_raid_redundancy() fails as a result of that because it checks the total number of devices against the number of rebuild ones rather than the actual ones in the raid set (as retrieved from the superblock) thus resulting in failed raid4/5/6/10 redundancy checks. E.g. convert 3 stripes -> 7 stripes raid5 (which only allows for maximum 1 device to fail) requesting +4 delta disks causing 4 devices to rebuild during reshaping thus failing activation. To fix this, move validate_raid_redundancy() to get access to the current raid_set members. Signed-off-by: Heinz Mauelshagen <heinzm@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>

2017-07-25udp: preserve head state for IP_CMSG_PASSSECPaolo Abeni
Paul Moore reported a SELinux/IP_PASSSEC regression caused by missing skb->sp at recvmsg() time. We need to preserve the skb head state to process the IP_CMSG_PASSSEC cmsg. With this commit we avoid releasing the skb head state in the BH even if a secpath is attached to the current skb, and stores the skb status (with/without head states) in the scratch area, so that we can access it at skb deallocation time, without incurring in cache-miss penalties. This also avoids misusing the skb CB for ipv6 packets, as introduced by the commit 0ddf3fb2c43d ("udp: preserve skb->dst if required for IP options processing"). Clean a bit the scratch area helpers implementation, to reduce the code differences between 32 and 64 bits build.

2017-07-25parisc: Fix crash when calling PDC_PAT_MEM PDT firmware functionHelge Deller
Commit c9c2877d08d9 ("parisc: Add Page Deallocation Table (PDT) support") introduced the pdc_pat_mem_read_pd_pdt() firmware helper function, which crashed the system because it trashed the stack if the pdc_pat_mem_read_pd_retinfo struct was located on the stack (and which is in size less than the required 32 64-bit values). Fix it by using the pdc_result struct instead when calling firmware and copy the return values back into the result struct when finished sucessfully. While debugging this code I noticed that the pdc_type wasn't set correctly either, so let's fix that too.

2017-07-25nvme-pci: fix HMB size calculationChristoph Hellwig
It's possible the preferred HMB size may not be a multiple of the chunk_size. This patch moves len to function scope and uses that in the for loop increment so the last iteration doesn't cause the total size to exceed the allocated HMB size. Based on an earlier patch from Keith Busch.

2017-07-25nvme-fc: revise TRADDR parsingJames Smart
The FC-NVME spec hasn't locked down on the format string for TRADDR. Currently the spec is lobbying for "nn-<16hexdigits>:pn-<16hexdigits>" where the wwn's are hex values but not prefixed by 0x. Most implementations so far expect a string format of "nn-0x<16hexdigits>:pn-0x<16hexdigits>" to be used. The transport uses the match_u64 parser which requires a leading 0x prefix to set the base properly. If it's not there, a match will either fail or return a base 10 value. The resolution in T11 is pushing out. Therefore, to fix things now and to cover any eventuality and any implementations already in the field, this patch adds support for both formats. The change consists of replacing the token matching routine with a routine that validates the fixed string format, and then builds a local copy of the hex name with a 0x prefix before calling the system parser. Note: the same parser routine exists in both the initiator and target transports. Given this is about the only "shared" item, we chose to replicate rather than create an interdendency on some shared code.
