From: Mario Limonciello <[email protected]>

commit 1fb710793ce2619223adffaf981b1ff13cd48f17 upstream.

The MES set resources packet has an optional bit 'lr_compute_wa' which can be used for preventing MES hangs on long compute jobs.

Set this bit by default.

commit e798f2ac6040f46a04795d7de977341fa9aeabae upstream.

This ID appears to be RTL8188SU, not RTL8188CU. This is the wrong driver for RTL8188SU. The r8712u driver from staging used to handle this ID.

commit c2783c7cfefd55b1a5be781679cbee5191c0fd87 upstream.

These srctree/ links pointed inside linux/, but they are directly under drm/.

Thus fix them.

This cleans a future warning that will check our srctree/ links.

commit a699213d4e6ef4286348c6439837990f121e0c03 upstream.

Revert commit 1afa70632c39 ("serial: qcom-geni: Enable PM runtime for serial driver") and its dependent commit 86fa39dd6fb7 ("serial:
qcom-geni: Enable Serial on SA8255p Qualcomm platforms") because the first one causes regression - hang task on Qualcomm RB1 board (QRB2210) and unable to use serial at all during normal boot:

The issue was reported on 12th of August and was ignored by author of commits introducing issue for two weeks. Only after complaining author produced a fix which did not work, so if original commits cannot be reliably fixed for 5 weeks, they obviously are buggy and need to be dropped.

commit 3ebcd3460cad351f198c39c6edb4af519a0ed934 upstream.

A process might fail to allocate a new bitmap when trying to expand its proc->dmap. In that case, dbitmap_grow() fails and frees the old bitmap via dbitmap_free(). However, the driver calls dbitmap_free() again when the same process terminates, leading to a double-free error:

From: Ovidiu Panait <[email protected]>

commit 52ff2b840bc723f3be1f096f8017c78e0515858c upstream.

Since commit 2ca34b508774 ("staging: axis-fifo: Correct handling of tx_fifo_depth for size validation"), write() operations with packets larger than 'tx_fifo_depth - 4' words are no longer rejected with -EINVAL.

Fortunately, the packets are not actually getting transmitted to hardware, otherwise they would be raising a 'Transmit Packet Overrun Error' interrupt, which requires a reset of the TX circuit to recover from.

Instead, the request times out inside wait_event_interruptible_timeout() and always returns -EAGAIN, since the wake up condition can never be true for these packets. But still, they unnecessarily block other tasks from writing to the FIFO and the EAGAIN return code signals userspace to retry the write() call, even though it will always fail and time out.

According to the AXI4-Stream FIFO reference manual (PG080), the maximum valid packet length is 'tx_fifo_depth - 4' words, so attempting to send larger packets is invalid and should not be happening in the first place:

Therefore, bring back the old behavior and outright reject packets larger than 'tx_fifo_depth - 4' with -EINVAL. Add a comment to explain why the check is necessary. The dev_err() message was removed to avoid cluttering the dmesg log if an invalid packet is received from userspace.

commit 6d07bee10e4bdd043ec7152cbbb9deb27033c9e2 upstream.

If copy_from_user() fails, write() currently returns -EFAULT, but any partially written data leaves the TX FIFO in an inconsistent state. Subsequent write() calls then fail with "transmit length mismatch" errors.

Once partial data is written to the hardware FIFO, it cannot be removed without a TX reset. Commit c6e8d85fafa7 ("staging: axis-fifo: Remove hardware resets for user errors") removed a full FIFO reset for this case, which fixed a potential RX data loss, but introduced this TX issue.

Fix this by introducing a bounce buffer: copy the full packet from userspace first, and write to the hardware FIFO only if the copy was successful.

commit c2ce2453413d429e302659abc5ace634e873f6f5 upstream.

Devices with power.no_pm set are not expected to need any power management at all, so modify device_set_pm_not_required() to set power.no_callbacks for them too in case runtime PM will be enabled for any of them (which in principle may be done for convenience if such a device participates in a dependency chain).

Since device_set_pm_not_required() must be called before device_add() or it would not have any effect, it can update power.no_callbacks without locking, unlike pm_runtime_no_callbacks() that can be called after registering the target device.

This happens because of a race condition between:

- The 9p client sending an invalid flush request and later cleaning it up;
- The 9p client in p9_read_work() canceled all pending requests.

Commit 74d6a5d56629 ("9p/trans_fd: Fix concurrency del of req_list in p9_fd_cancelled/p9_read_work") fixes a concurrency issue in the 9p filesystem client where the req_list could be deleted simultaneously by both p9_read_work and p9_fd_cancelled functions, but for the case where req->status equals REQ_STATUS_RCVD.

Update the check for req->status in p9_fd_cancelled to skip processing not just received requests, but anything that is not SENT, as whatever changed the state from SENT also removed the request from its list.

Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

commit e750f85391286a4c8100275516973324b621a269 upstream.

When completing emulation of instruction that generated a userspace exit for I/O, don't recheck L1 intercepts as KVM has already finished that phase of instruction execution, i.e. has already committed to allowing L2 to perform I/O. If L1 (or host userspace) modifies the I/O permission bitmaps during the exit to userspace, KVM will treat the access as being intercepted despite already having emulated the I/O access.

Pivot on EMULTYPE_NO_DECODE to detect that KVM is completing emulation. Of the three users of EMULTYPE_NO_DECODE, only complete_emulated_io() (the intended "recipient") can reach the code in question. gp_interception()'s use is mutually exclusive with is_guest_mode(), and complete_emulated_insn_gp() unconditionally pairs EMULTYPE_NO_DECODE with EMULTYPE_SKIP.

The bad behavior was detected by a syzkaller program that toggles port I/O interception during the userspace I/O exit, ultimately resulting in a WARN on vcpu->arch.pio.count being non-zero due to KVM no completing emulation of the I/O instruction.

w/ a fuzzed image, f2fs may encounter panic due to it detects inconsistent truncation range in direct node in f2fs_truncate_hole().

The root cause is: a non-inode dnode may has the same footer.ino and footer.nid, so the dnode will be parsed as an inode, then ADDRS_PER_PAGE() may return wrong blkaddr count which may be 923 typically, by chance, dn.ofs_in_node is equal to 923, then count can be calculated to 0 in below statement, later it will trigger panic w/ f2fs_bug_on(, count == 0 || ...).

	count = min(end_offset - dn.ofs_in_node, pg_end - pg_start);

This patch introduces a new node_type NODE_TYPE_NON_INODE, then allowing passing the new_type to sanity_check_node_footer in f2fs_get_node_folio() to detect corruption that a non-inode dnode has the same footer.ino and footer.nid.

Scripts to reproduce:

mount /dev/vdb /mnt/f2fs
touch /mnt/f2fs/foo

commit de4cbd704731778a2dc833ce5a24b38e5d672c05 upstream.

The return value from __rb_map_vma(), which rejects writable or executable mappings (VM_WRITE, VM_EXEC, or !VM_MAYSHARE), was being ignored. As a result the caller of __rb_map_vma always returned 0 even when the mapping had actually failed, allowing it to proceed with an invalid VMA.

Climb the mountain not to plant your flag, but to embrace the challenge,
enjoy the air and behold the view. Climb it so you can see the world,
not so the world can see you.                    -- David McCullough Jr.
