In "drm/i915: Add support for mandatory cmdparsing" we introduced the concept of mandatory parsing. This allows the cmdparser to be invoked even when user passes batch_len=0 to the execbuf ioctl's. However, the cmdparser needs to know the extents of the buffer being scanned. Refactor the code to ensure the cmdparser uses the actual object size, instead of the incoming length, if user passes 0.

For Gen7, the original cmdparser motive was to permit limited use of register read/write instructions in unprivileged BB's. This worked by copying the user supplied bb to a kmd owned bb, and running it in secure mode, from the ggtt, only if the scanner finds no unsafe commands or registers. For Gen8+ we can't use this same technique because running bb's from the ggtt also disables access to ppgtt space. But we also do not actually require 'secure' execution since we are only trying to reduce the available command/register set. Instead we will copy the user buffer to a kmd owned read-only bb in ppgtt, and run in the usual non-secure mode. Note that ro pages are only supported by ppgtt (not ggtt), but luckily that's exactly what we need. Add the required paths to map the shadow buffer to ppgtt ro for Gen8+ v2: IS_GEN7/IS_GEN (Mika) v3: rebase v4: rebase v5: rebase Signed-off-by:

The existing cmdparser for gen7 can be bypassed by specifying batch_len=0 in the execbuf call. This is safe because bypassing simply reduces the cmd-set available. In a later patch we will introduce cmdparsing for gen9, as a security measure, which must be strictly enforced since without it we are vulnerable to DoS attacks. Introduce the concept of 'required' cmd parsing that cannot be bypassed by submitting zero-length bb's. v2: rebase (Mika) v2: rebase (Mika) v3: fix conflict on engine flags (Mika) Signed-off-by:

Jon Bloomfield authored
Retroactively stop reporting support for secure batches through the api for gen6+ so that older binaries trigger the fallback path instead. Older binaries use secure batches pre gen6 to access resources that are not available to normal usermode processes. However, all known userspace explicitly checks for HAS_SECURE_BATCHES before relying on the secure batch feature. Since there are no known binaries relying on this for newer gens we can kill secure batches from gen6, via I915_PARAM_HAS_SECURE_BATCHES. v2: rebase (Mika) v3: rebase (Mika) Signed-off-by:

The KUAP (SMAP) support we added for 32-bit Book3S had a bug if the address range crossed a segment (256MB) boundary which could lead to spurious faults.

When netdevice with offloaded BPF programs is destroyed the programs are orphaned and removed from the program IDA - their IDs get released (the programs may remain accessible via existing open file descriptors and pinned files). After IDs are released they are set to 0. This confuses dev_change_xdp_fd() because it compares the __dev_xdp_query() result where 0 means no program with prog->aux->id where 0 means orphaned. dev_change_xdp_fd() would have incorrectly returned success even though it had not installed the program. Since drivers already catch this case via bpf_offload_dev_match() let them handle this case. The error message drivers produce in this case ("program loaded for a different device") is in fact correct as the orphaned program must had to be loaded for a different device.

Historically linux tried to stick to RFC 791, 1122, 2003 for IPv4 ID field generation. RFC 6864 made clear that no matter how hard we try, we can not ensure unicity of IP ID within maximum lifetime for all datagrams with a given source address/destination address/protocol tuple. Linux uses a per socket inet generator (inet_id), initialized at connection startup with a XOR of 'jiffies' and other fields that appear clear on the wire. Thiemo Nagel pointed that this strategy is a privacy concern as this provides 16 bits of entropy to fingerprint devices. Let's switch to a random starting point, this is just as good as far as RFC 6864 is concerned and does not leak anything critical. Fixes: 1da177e4 ("Linux-2.6.12-rc2") Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2019-11-01 This series contains updates to e1000, igb, igc, ixgbe, i40e and driver documentation. Lyude Paul fixes an issue where a fatal read error occurs when the device is unplugged from the machine. So change the read error into a warn while the device is still present. Manfred Rudigier found that the i350 device was not apart of the "Media Auto Sense" feature, yet the device supports it. So add the missing i350 device to the check and fix an issue where the media auto sense would flip/flop when no cable was connected to the port causing spurious kernel log messages. I fixed an issue where the fix to resolve receive buffer starvation was applied in more than one place in the driver, one being the incorrect location in the i40e driver. Wenwen Wang fixes a potential memory leak in e1000 where allocated memory is not properly cleaned up in one of the error paths. Jonathan Neuschäfer cleans up the driver documentation to be consistent and remove the footnote reference, since the footnote no longer exists in the documentation.

At least on the i350 there is an annoying behavior that is maybe also present on 82580 devices, but was probably not noticed yet as MAS is not widely used. If no cable is connected on both fiber/copper ports the media auto sense code will constantly swap between them as part of the watchdog task and produce many unnecessary kernel log messages. The swap code responsible for this behavior (switching to fiber) should not be executed if the current media type is copper and there is no signal detected on the fiber port. In this case we can safely wait until the AUTOSENSE_EN bit is cleared. Signed-off-by:
