drm/xe/userptr: fix EFAULT handling
Currently we treat EFAULT from hmm_range_fault() as a non-fatal error
when called from xe_vm_userptr_pin() with the idea that we want to avoid
killing the entire vm and chucking an error, under the assumption that
the user just did an unmap or something, and has no intention of
actually touching that memory from the GPU. At this point we have
already zapped the PTEs so any access should generate a page fault, and
if the pin fails there also it will then become fatal.
However it looks like it's possible for the userptr vma to still be on
the rebind list in preempt_rebind_work_func(), if we had to retry the
pin again due to something happening in the caller before we did the
rebind step, but in the meantime needing to re-validate the userptr and
this time hitting the EFAULT.
This explains an internal user report of hitting:

Followed by NPD, when running some workload, since the sg was never
actually populated but the vma is still marked for rebind when it should
be skipped for this special EFAULT case. This is confirmed to fix the
user report.
v2 (MattB):
- Move earlier.
v3 (MattB):
- Update the commit message to make it clear that this indeed fixes the
issue.
(cherry picked from commit 6b93cb98910c826c2e2004942f8b060311e43618) |
| An improper check or handling of exceptional conditions in NPU driver prior to SMR Jan-2022 Release 1 allows arbitrary memory write and code execution. |
| Improper access control in clipboard service in Samsung mobile devices prior to SMR Mar-2021 Release 1 allows untrusted applications to read or write certain local files. |
| An improper access control vulnerability in sec_log file prior to SMR MAR-2021 Release 1 exposes sensitive kernel information to userspace. |
| A vulnerability in DSP driver prior to SMR Mar-2021 Release 1 allows attackers load arbitrary ELF libraries inside DSP. |
| A use after free vulnerability via race condition in MFC charger driver prior to SMR MAY-2021 Release 1 allows arbitrary write given a radio privilege is compromised. |
| A race condition in MFC charger driver prior to SMR MAY-2021 Release 1 allows local attackers to bypass signature check given a radio privilege is compromised. |
| Lack of boundary checking of a buffer in set_skb_priv() of modem interface driver prior to SMR Oct-2021 Release 1 allows OOB read and it results in arbitrary code execution by dereference of invalid function pointer. |
| Assuming radio permission is gained, missing input validation in modem interface driver prior to SMR Oct-2021 Release 1 results in format string bug leading to kernel panic. |
| A stored cross-site scripting (XSS) vulnerability exists in automatic1111/stable-diffusion-webui version git 82a973c. An attacker can upload an HTML file, which the application interprets as content-type application/html. If a victim accesses the malicious link, it will execute arbitrary JavaScript in the victim's browser. |
| A local file inclusion vulnerability was identified in automatic1111/stable-diffusion-webui, affecting version git 82a973c. This vulnerability allows an attacker to read arbitrary files on the system by sending a specially crafted request to the application. |
| Insecure Direct Object Reference (IDOR) in /tenants/{id} API endpoint in Inforcer Platform version 2.0.153 allows an authenticated user with low privileges to enumerate and access tenant information belonging to other clients via modification of the tenant ID in the request URL. |
| Incorrect access control in the kernel driver of ThreatFire System Monitor v4.7.0.53 allows attackers to escalate privileges and execute arbitrary commands via an insecure IOCTL. |
| memoQ 10.1.13.ef1b2b52aae and earlier contains an unquoted service path vulnerability in the memoQ Auto Update Service (memoQauhlp101). The affected service is installed with a path containing spaces and without surrounding quotes. This misconfiguration allows local users to escalate privileges to SYSTEM by placing a malicious executable at C:\Program.exe. |
| On affected platforms, if SSH session multiplexing was configured on the client side, SSH sessions (e.g, scp, sftp) multiplexed onto the same channel could perform file-system operations after a configured session timeout expired |
| On affected platforms, restricted users could use SSH port forwarding to access host-internal services |
| On affected platforms, a restricted user could break out of the CLI sandbox to the system shell and elevate their privileges. |
| StarCharge Artemis AC Charger 7-22 kW v1.0.4 was discovered to contain a stack overflow via the cgiMain function at download.cgi. |
| In the Linux kernel, the following vulnerability has been resolved:
staging: gpib: Fix Oops after disconnect in ni_usb
If the usb dongle is disconnected subsequent calls to the
driver cause a NULL dereference Oops as the bus_interface
is set to NULL on disconnect.
This problem was introduced by setting usb_dev from the bus_interface
for dev_xxx messages.
Previously bus_interface was checked for NULL only in the the functions
directly calling usb_fill_bulk_urb or usb_control_msg.
Check for valid bus_interface on all interface entry points
and return -ENODEV if it is NULL. |
