DSN read can fail, for example on a kdump kernel without PCIe extended config space support. If DSN read fails, don't set the BNXT_FLAG_DSN_VALID flag and continue loading. Check the flag to see if the stored DSN is valid before using it. Only VF reps creation should fail without valid DSN.

2020-01-18ptrace: reintroduce usage of subjective credentials in ptrace_has_cap()Christian Brauner
Commit 69f594a38967 ("ptrace: do not audit capability check when outputing /proc/pid/stat") introduced the ability to opt out of audit messages for accesses to various proc files since they are not violations of policy. While doing so it somehow switched the check from ns_capable() to has_ns_capability{_noaudit}(). That means it switched from checking the subjective credentials of the task to using the objective credentials. This is wrong since. ptrace_has_cap() is currently only used in ptrace_may_access() And is used to check whether the calling task (subject) has the CAP_SYS_PTRACE capability in the provided user namespace to operate on the target task (object). According to the cred.h comments this would mean the subjective credentials of the calling task need to be used. This switches ptrace_has_cap() to use security_capable(). Because we only call ptrace_has_cap() in ptrace_may_access() and in there we already have a stable reference to the calling task's creds under rcu_read_lock() there's no need to go through another series of dereferences and rcu locking done in ns_capable{_noaudit}(). As one example where this might be particularly problematic, Jann pointed out that in combination with the upcoming IORING_OP_OPENAT feature, this bug might allow unprivileged users to bypass the capability checks while asynchronously opening files like /proc/*/mem, because the capability checks for this would be performed against kernel credentials. To illustrate on the former point about this being exploitable: When io_uring creates a new context it records the subjective credentials of the caller. Later on, when it starts to do work it creates a kernel thread and registers a callback. The callback runs with kernel creds for ktask->real_cred and ktask->cred. To prevent this from becoming a full-blown 0-day io_uring will call override_cred() and override ktask->cred with the subjective credentials of the creator of the io_uring instance. With ptrace_has_cap() currently looking at ktask->real_cred this override will be ineffective and the caller will be able to open arbitray proc files as mentioned above. Luckily, this is currently not exploitable but will turn into a 0-day once IORING_OP_OPENAT{2} land in v5.6. Fix it now!

2020-01-18iio: adc: ad7124: Set IRQ type to fallingAlexandru Tachici
Ad7124 data-sheet specifies that the falling edge of the DOUT line should be used for an interrupt. The current irq flag (IRQF_TRIGGER_LOW) used will cause unwanted behaviour. When enabling the interrupt it will fire once because the DOUT line is already low. This will make the driver to read an unfinished conversion from the chip.

2020-01-18MAINTAINERS: Mark simple firmware interface (SFI) obsoleteLukas Bulwahn
Len Brown has not been active in this part since around 2010 and confirmed that he is not maintaining this part of the kernel sources anymore and the git log suggests that nobody is actively maintaining it. The referenced git tree does not exist. Instead, I found an sfi branch in Len's kernel git repository, but that has not been updated since 2014; so that is not worth to be mentioned in MAINTAINERS now anymore either. Len Brown expects no further systems to be shipped with SFI, so we can mark it obsolete and schedule it for deletion. This change was motivated after I found that I could not send any mails to the sfi-devel mailing list, and that the mailing list does not exist anymore.

2020-01-17drm/dp_mst: Handle SST-only branch device caseWayne Lin
[Why] While handling LINK_ADDRESS reply, current code expects a peer device can handle sideband message once the peer device type is reported as DP_PEER_DEVICE_MST_BRANCHING. However, when the connected device is a SST branch case, it can't handle the sideband message(MST_CAP=0 in DPCD 00021h). Current code will try to send LINK_ADDRESS to SST branch device and end up with message timeout and monitor can't display normally. As the result of that, we should take SST branch device into account. [How] According to DP 1.4 spec, we can use Peer_Device_Type as DP_PEER_DEVICE_MST_BRANCHING and Message_Capability_Status as 0 to indicate peer device as a SST-only branch device. Fix following: - Add the function drm_dp_mst_is_dp_mst_end_device() to decide whether a peer device connected to a DFP is mst end device. Which also indicates if the peer device is capable of handling message or not. - Take SST-only branch device case into account in drm_dp_port_set_pdt() and add a new parameter 'new_mcs'. Take sst branch device case as the same case as DP_PEER_DEVICE_DP_LEGACY_CONV and DP_PEER_DEVICE_SST_SINK. All original handling logics remain. - Take SST-only branch device case into account in drm_dp_mst_port_add_connector(). - Fix some parts in drm_dp_mst_handle_link_address_port() to have SST branch device case into consideration. - Fix the arguments of drm_dp_port_set_pdt() in drm_dp_mst_handle_conn_stat(). - Have SST branch device also report connector_status_connected when the ddps is true in drm_dp_mst_detect_port() - Fix the arguments of drm_dp_port_set_pdt() in drm_dp_delayed_destroy_port() Changes since v1:(https://patchwork.kernel.org/patch/11323079/) * Squash previous patch into one patch and merge the commit message here. * Combine the if statements mentioned in comments Fixes: c485e2c97dae ("drm/dp_mst: Refactor pdt setup/teardown, add more locking") Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Harry Wentland <hwentlan@amd.com> Cc: Lyude Paul <lyude@redhat.com> Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200117060350.26358-2-Wayne.Lin@amd.com

Notably the bind attributes for usb-serial (port) drivers are removed as almost none of the drivers can handle individual ports going away once they've been bound. Included are also some new device ids. All but the unbound-port fixes have been in linux-next with no reported issues.

2020-01-17x86/resctrl: Check monitoring static key in the MBM overflow handlerXiaochen Shen
Currently, there are three static keys in the resctrl file system: rdt_mon_enable_key and rdt_alloc_enable_key indicate if the monitoring feature and the allocation feature are enabled, respectively. The rdt_enable_key is enabled when either the monitoring feature or the allocation feature is enabled. If no monitoring feature is present (either hardware doesn't support a monitoring feature or the feature is disabled by the kernel command line option "rdt="), rdt_enable_key is still enabled but rdt_mon_enable_key is disabled. MBM is a monitoring feature. The MBM overflow handler intends to check if the monitoring feature is not enabled for fast return. So check the rdt_mon_enable_key in it instead of the rdt_enable_key as former is the more accurate check.

2020-01-17x86/cpu: Update cached HLE state on write to TSX_CTRL_CPUID_CLEARPawan Gupta
/proc/cpuinfo currently reports Hardware Lock Elision (HLE) feature to be present on boot cpu even if it was disabled during the bootup. This is because cpuinfo_x86->x86_capability HLE bit is not updated after TSX state is changed via the new MSR IA32_TSX_CTRL. Update the cached HLE bit also since it is expected to change after an update to CPUID_CLEAR bit in MSR IA32_TSX_CTRL.

2020-01-17ice: Removing hung_queue variable to use txqueue function parameterJulio Faracco
The scope of function .ndo_tx_timeout was changed to include the hang queue when a TX timeout event occurs. See commit 0290bd291cc0 ("netdev: pass the stuck queue to the timeout handler") for more details. Now, drivers don't need to identify which queue is stopped. Drivers can simply use the queue index provided by dev_watchdog and execute all actions needed to restore network traffic. This commit do some cleanups into Intel ice driver to remove a redundant loop to find stopped queue.

2020-01-17fm10k: use txqueue parameter in fm10k_tx_timeoutJacob Keller
Make use of the new txqueue parameter to the .ndo_tx_timeout function. In fm10k_tx_timeout, remove the now unnecessary loop to determine which Tx queue is stuck. Instead, just double check the specified queue This could be improved further to attempt resetting only the specific queue that got stuck. However, that is a much larger refactor and has been left as a future improvement.
