If some part of the kernel adds task_work that needs executing, in terms
of signaling it'll generally use TWA_SIGNAL or TWA_RESUME. Those two
directly translate to TIF_NOTIFY_SIGNAL or TIF_NOTIFY_RESUME, and can
be used for a variety of use case outside of task_work.
However, io_cqring_wait_schedule() only tests explicitly for
TIF_NOTIFY_SIGNAL. This means it can miss if task_work got added for
the task, but used a different kind of signaling mechanism (or none at
all). Normally this doesn't matter as any task_work will be run once
the task exits to userspace, except if:
1) The ring is setup with DEFER_TASKRUN
2) The local work item may generate normal task_work
For condition 2, this can happen when closing a file and it's the final
put of that file, for example. This can cause stalls where a task is
waiting to make progress inside io_cqring_wait(), but there's nothing else
that will wake it up. Hence change the "should we schedule or loop around"
check to check for the presence of task_work explicitly, rather than just
TIF_NOTIFY_SIGNAL as the mechanism. While in there, also change the
ordering of what type of task_work first in terms of ordering, to both
make it consistent with other task_work runs in io_uring, but also to
better handle the case of defer task_work generating normal task_work,
like in the above example.

Pull scheduler updates from Ingo Molnar:
- Implement the SCHED_DEADLINE server infrastructure - Daniel Bristot
de Oliveira's last major contribution to the kernel:
"SCHED_DEADLINE servers can help fixing starvation issues of low
priority tasks (e.g., SCHED_OTHER) when higher priority tasks
monopolize CPU cycles. Today we have RT Throttling; DEADLINE
servers should be able to replace and improve that."
(Daniel Bristot de Oliveira, Peter Zijlstra, Joel Fernandes, Youssef
Esmat, Huang Shijie)
- Preparatory changes for sched_ext integration:
- Use set_next_task(.first) where required
- Fix up set_next_task() implementations
- Clean up DL server vs. core sched
- Split up put_prev_task_balance()
- Rework pick_next_task()
- Combine the last put_prev_task() and the first set_next_task()
- Rework dl_server
- Add put_prev_task(.next)
(Peter Zijlstra, with a fix by Tejun Heo)
- Complete the EEVDF transition and refine EEVDF scheduling:
- Implement delayed dequeue
- Allow shorter slices to wakeup-preempt
- Use sched_attr::sched_runtime to set request/slice suggestion
- Document the new feature flags
- Remove unused and duplicate-functionality fields
- Simplify & unify pick_next_task_fair()
- Misc debuggability enhancements
(Peter Zijlstra, with fixes/cleanups by Dietmar Eggemann, Valentin
Schneider and Chuyi Zhou)
- Initialize the vruntime of a new task when it is first enqueued,
resulting in significant decrease in latency of newly woken tasks
(Zhang Qiao)
- Introduce SM_IDLE and an idle re-entry fast-path in __schedule()

Condition
In the ether3_probe function, a timer is initialized with a callback
function ether3_ledoff, bound to &prev(dev)->timer. Once the timer is
started, there is a risk of a race condition if the module or device
is removed, triggering the ether3_remove function to perform cleanup.
The sequence of operations that may lead to a UAF bug is as follows:
CPU0 CPU1
| ether3_ledoff
ether3_remove |
free_netdev(dev); |
put_devic |
kfree(dev); |
| ether3_outw(priv(dev)->regs.config2 |= CFG2_CTRLO, REG_CONFIG2);
| // use dev
Fix it by ensuring that the timer is canceled before proceeding with
the cleanup in ether3_remove.

axienet_free_tx_chain returns the number of DMA descriptors it's
handled. However, axienet_tx_poll treats the return as the number of
packets. When scatter-gather SKBs are enabled, a single packet may use
multiple DMA descriptors, which causes incorrect packet counts. Fix this
by explicitly keepting track of the number of packets processed as
separate from the DMA descriptors.
Budget does not affect the number of Tx completions we can process for
NAPI, so we use the ring size as the limit instead of budget. As we no
longer return the number of descriptors processed to axienet_tx_poll, we
now update tx_bd_ci in axienet_free_tx_chain.

Pull i2c fixes from Wolfram Sang:
"The Aspeed driver tracks the controller's state (stop, pending, start,
etc.). Previously, when the stop command was sent, the state was not
updated. The fix ensures the driver's state is aligned with the device
status.
The Intel SCH driver receives a new look, and among the cleanups,
there is a fix where, due to an oversight, an if/else statement was
missing the else, causing it to move forward instead of exiting the
function in case of an error.
The Qualcomm GENI I2C driver adds the IRQF_NO_AUTOEN flag to the IRQ
setup to prevent unwanted interrupts during probe.
The Xilinx XPS controller fixes TX FIFO handling to avoid missed NAKs.

It's important to undo pm_runtime_use_autosuspend() with
pm_runtime_dont_use_autosuspend() at driver exit time unless driver
initially enabled pm_runtime with devm_pm_runtime_enable()
(which handles it for you).

It's important to undo pm_runtime_use_autosuspend() with
pm_runtime_dont_use_autosuspend() at driver exit time unless driver
initially enabled pm_runtime with devm_pm_runtime_enable()
(which handles it for you).
Hence, call pm_runtime_dont_use_autosuspend() at driver exit time
to fix it.

The author of the blamed commit apparently did not notice something
about aqr_wait_reset_complete(): it polls the exact same register -
MDIO_MMD_VEND1:VEND1_GLOBAL_FW_ID - as aqr_firmware_load().
Thus, the entire logic after the introduction of aqr_wait_reset_complete() is
now completely side-stepped, because if aqr_wait_reset_complete()
succeeds, MDIO_MMD_VEND1:VEND1_GLOBAL_FW_ID could have only been a
non-zero value. The handling of the case where the register reads as 0
is dead code, due to the previous -ETIMEDOUT having stopped execution
and returning a fatal error to the caller. We never attempt to load
new firmware if no firmware is present.
Based on static code analysis, I guess we should simply introduce a
switch/case statement based on the return code from aqr_wait_reset_complete(),
to determine whether to load firmware or not. I am not intending to
change the procedure through which the driver determines whether to load
firmware or not, as I am unaware of alternative possibilities.
At the same time, Russell King suggests that if aqr_wait_reset_complete()
is expected to return -ETIMEDOUT as part of normal operation and not
just catastrophic failure, the use of phy_read_mmd_poll_timeout() is
improper, since that has an embedded print inside. Just open-code a
call to read_poll_timeout() to avoid printing -ETIMEDOUT, but continue
printing actual read errors from the MDIO bus.

The remap_file_pages syscall handler calls do_mmap() directly, which
doesn't contain the LSM security check. And if the process has called
personality(READ_IMPLIES_EXEC) before and remap_file_pages() is called for
RW pages, this will actually result in remapping the pages to RWX,
bypassing a W^X policy enforced by SELinux.
So we should check prot by security_mmap_file LSM hook in the
remap_file_pages syscall handler before do_mmap() is called. Otherwise, it
potentially permits an attacker to bypass a W^X policy enforced by
SELinux.
The bypass is similar to CVE-2016-10044, which bypass the same thing via
AIO and can be found in [1].
The PoC:
$ cat > test.c
int main(void) {
size_t pagesz = sysconf(_SC_PAGE_SIZE);
int mfd = syscall(SYS_memfd_create, "test", 0);
const char *buf = mmap(NULL, 4 * pagesz, PROT_READ | PROT_WRITE,
MAP_SHARED, mfd, 0);
unsigned int old = syscall(SYS_personality, 0xffffffff);
syscall(SYS_personality, READ_IMPLIES_EXEC | old);
syscall(SYS_remap_file_pages, buf, pagesz, 0, 2, 0);
syscall(SYS_personality, old);
// show the RWX page exists even if W^X policy is enforced
int fd = open("/proc/self/maps", O_RDONLY);
unsigned char buf2[1024];
while (1) {
int ret = read(fd, buf2, 1024);
if (ret <= 0) break;
write(1, buf2, ret);
}
close(fd);

Only f_path is used from backing files registered with
FUSE_DEV_IOC_BACKING_OPEN, so it makes sense to allow O_PATH descriptors.
O_PATH files have an empty f_op, so don't check read_iter/write_iter.

Pull parisc architecture updates from Helge Deller:
- On parisc we now use the generic clockevent framework for timekeeping
- Although there is no 64-bit glibc/userspace for parisc yet, for
testing purposes one can run statically linked 64-bit binaries. This
patchset contains two patches which fix 64-bit userspace which has
been broken since kernel 4.19
- Fix the userspace stack position and size when the ADDR_NO_RANDOMIZE
personality is enabled
- On other architectures mmap(MAP_GROWSDOWN | MAP_STACK) creates a
downward-growing stack. On parisc mmap(MAP_STACK) is now sufficient
to create an upward-growing stack

"New code:
- Introduce new ioctls to exchange contents of two files.
The first ioctl does the preparation work to exchange the contents
of two files while the second ioctl performs the actual exchange if

Fixes:
- Fix bugs associated with calculating the maximum range of realtime
extents to scan for free space.
- Copy keys instead of records when resizing the incore BMBT root
block.
- Do not report FITRIMming more bytes than possibly exist in the
filesystem.
- Modify xfs_fs.h to prevent C++ compilation errors.
- Do not over eagerly free post-EOF speculative preallocation.
- Ensure st_blocks never goes to zero during COW writes

- realtime bitmap
- inode allocator
- quota
