This is a real pain when sysctl kernel.shm_rmid_forced = 1, because it leads to use-after-free (reproducer exists). This is an attempt to fix the problem by extending exit_shm mechanism to handle shm's destroy from several IPC ns'es. To achieve that we do several things: 1. add a namespace (non-refcounted) pointer to the struct shmid_kernel 2. during new shm object creation (newseg()/shmget syscall) we initialize this pointer by current task IPC ns 3. exit_shm() fully reworked such that it traverses over all shp's in task->sysvshm.shm_clist and gets IPC namespace not from current task as it was before but from shp's object itself, then call shm_destroy(shp, ns). Note: We need to be really careful here, because as it was said before (1), our pointer to IPC ns non-refcnt'ed. To be on the safe side we using special helper get_ipc_ns_not_zero() which allows to get IPC ns refcounter only if IPC ns not in the "state of destruction". Q/A Q: Why can we access shp->ns memory using non-refcounted pointer? A: Because shp object lifetime is always shorther than IPC namespace lifetime, so, if we get shp object from the task->sysvshm.shm_clist while holding task_lock(task) nobody can steal our namespace. Q: Does this patch change semantics of unshare/setns/clone syscalls? A: No. It's just fixes non-covered case when process may leave IPC namespace without getting task->sysvshm.shm_clist list cleaned up.

Some time ago I met kernel crash after CRIU restore procedure, fortunately, it was CRIU restore, so, I had dump files and could do restore many times and crash reproduced easily. After some investigation I've constructed the minimal reproducer. It was found that it's use-after-free and it happens only if sysctl kernel.shm_rmid_forced = 1. The key of the problem is that the exit_shm() function not handles shp's object destroy when task->sysvshm.shm_clist contains items from different IPC namespaces. In most cases this list will contain only items from one IPC namespace. How can this list contain object from different namespaces? The exit_shm() function is designed to clean up this list always when process leaves IPC namespace. But we made a mistake a long time ago and did not add a exit_shm() call into the setns() syscall procedures. The first idea was just to add this call to setns() syscall but it obviously changes semantics of setns() syscall and that's userspace-visible change. So, I gave up on this idea. The first real attempt to address the issue was just to omit forced destroy if we meet shp object not from current task IPC namespace [1]. But that was not the best idea because task->sysvshm.shm_clist was protected by rwsem which belongs to current task IPC namespace. It means that list corruption may occur. Second approach is just extend exit_shm() to properly handle shp's from different IPC namespaces [2]. This is really non-trivial thing, I've put a lot of effort into that but not believed that it's possible to make it fully safe, clean and clear. Thanks to the efforts of Manfred Spraul working an elegant solution was designed. Thanks a lot, Manfred! Eric also suggested the way to address the issue in ("[RFC][PATCH] shm: In shm_exit destroy all created and never attached segments") Eric's idea was to maintain a list of shm_clists one per IPC namespace, use lock-less lists. But there is some extra memory consumption-related concerns. An alternative solution which was suggested by me was implemented in ("shm: reset shm_clist on setns but omit forced shm destroy"). The idea is pretty simple, we add exit_shm() syscall to setns() but DO NOT destroy shm segments even if sysctl kernel.shm_rmid_forced = 1, we just clean up the task->sysvshm.shm_clist list. This chages semantics of setns() syscall a little bit but in comparision to the "naive" solution when we just add exit_shm() without any special exclusions this looks like a safer option.

Request for cherry-picking USB-audio fixes to 5.15.x stable

by Takashi Iwai

Hi Greg, it seems that many reported issues for 5.15 and 5.14 kernels are fixed by the recent development on 5.16-rc, and it's worth to backport those to 5.15.x stable. Below is the list of commits from the mainline. Could you cherry-pick them to 5.15.x stable? Applying from top to bottom. I confirmed that they can be applied and built cleanly on 5.15.5. 4e7cf1fbb34ecb472c073980458cbe413afd4d64 9c9a3b9da891cc70405a544da6855700eddcbb71 e581f1cec4f899f788f6c9477f805b1d5fef25e2 bceee75387554f682638e719d1ea60125ea78cea d215f63d49da9a8803af3e81acd6cad743686573 0ef74366bc150dda4f53c546dfa6e8f7c707e087 d5f871f89e21bb71827ea57bd484eedea85839a0 813a17cab9b708bbb1e0db8902e19857b57196ec 23939115be181bc5dbc33aa8471adcdbffa28910 53451b6da8271905941eb1eb369db152c4bd92f2 eee5d6f1356a016105a974fb176b491288439efa 83de8f83816e8e15227dac985163e3d433a2bf9d The diffstat of those are like below: sound/usb/card.h | 10 ++- sound/usb/endpoint.c | 223 +++++++++++++++++++++++++++++++++++++-------------- sound/usb/endpoint.h | 13 ++- sound/usb/pcm.c | 165 +++++++++++++++++++++++++++++-------- 4 files changed, 306 insertions(+), 105 deletions(-) If you prefer, I can submit the patches, too.

[PATCH v2] drm/i915/dp: Perform 30ms delay after source OUI write

by Lyude Paul

While working on supporting the Intel HDR backlight interface, I noticed that there's a couple of laptops that will very rarely manage to boot up without detecting Intel HDR backlight support - even though it's supported on the system. One example of such a laptop is the Lenovo P17 1st generation. Following some investigation Ville Syrjälä did through the docs they have available to them, they discovered that there's actually supposed to be a 30ms wait after writing the source OUI before we begin setting up the rest of the backlight interface. This seems to be correct, as adding this 30ms delay seems to have completely fixed the probing issues I was previously seeing. So - let's start performing a 30ms wait after writing the OUI, which we do in a manner similar to how we keep track of PPS delays (e.g. record the timestamp of the OUI write, and then wait for however many ms are left since that timestamp right before we interact with the backlight) in order to avoid waiting any longer then we need to. As well, this also avoids us performing this delay on systems where we don't end up using the HDR backlight interface.

[PATCH V2] ifcvf/vDPA: fix misuse virtio-net device config size for blk dev

by Zhu Lingshan

This commit fixes a misuse of virtio-net device config size issue for virtio-block devices. A new member config_size in struct ifcvf_hw is introduced and would be initialized through vdpa_dev_add() to record correct device config size. To be more generic, rename ifcvf_hw.net_config to ifcvf_hw.dev_config, the helpers ifcvf_read/write_net_config() to ifcvf_read/write_dev_config() Signed-off-by: Zhu Lingshan <lingshan.zhu(a)intel.com> Reported-and-suggested-by: Stefano Garzarella <sgarzare(a)redhat.com> Reviewed-by: Stefano Garzarella <sgarzare(a)redhat.com> Fixes: 6ad31d162a4e ("vDPA/ifcvf: enable Intel C5000X-PL virtio-block for vDPA") Cc: <stable(a)vger.kernel.org> --- drivers/vdpa/ifcvf/ifcvf_base.c | 41 +++++++++++++++++++++++++-------- drivers/vdpa/ifcvf/ifcvf_base.h | 9 +++++--- drivers/vdpa/ifcvf/ifcvf_main.c | 24 ++++--------------- 3 files changed, 41 insertions(+), 33 deletions(-) diff --git a/drivers/vdpa/ifcvf/ifcvf_base.c b/drivers/vdpa/ifcvf/ifcvf_base.c index 2808f1ba9f7b..7d41dfe48ade 100644 --- a/drivers/vdpa/ifcvf/ifcvf_base.c +++ b/drivers/vdpa/ifcvf/ifcvf_base.c @@ -143,8 +143,8 @@ int ifcvf_init_hw(struct ifcvf_hw *hw, struct pci_dev *pdev) IFCVF_DBG(pdev, "hw->isr = %p\n", hw->isr);
