[PATCH v2 2/3] drm/nouveau: Add a dedicated mutex for the clients list

by Jeremy Cline

Rather than protecting the nouveau_drm clients list with the lock within the "client" nouveau_cli, add a dedicated lock to serialize access to the list. This is both clearer and necessary to avoid lockdep being upset with us when we need to iterate through all the clients in the list and potentially lock their mutex, which is the same class as the lock protecting the entire list.

[PATCH v2 1/3] drm/nouveau: use drm_dev_unplug() during device removal

by Jeremy Cline

Nouveau does not currently support hot-unplugging, but it still makes sense to switch from drm_dev_unregister() to drm_dev_unplug(). drm_dev_unplug() calls drm_dev_unregister() after marking the device as unplugged, but only after any device critical sections are finished. Since nouveau isn't using drm_dev_enter() and drm_dev_exit(), there are no critical sections so this is nearly functionally equivalent. However, the DRM layer does check to see if the device is unplugged, and if it is returns appropriate error codes. In the future nouveau can add critical sections in order to truly support hot-unplugging.

[PATCH] net: stmmac: fix incorrect merge of patch upstream

by Antonio Borneo

Commit 757926247836 ("net: stmmac: add flexible PPS to dwmac 4.10a") was intended to modify the struct dwmac410_ops, but it got somehow badly merged and modified the struct dwmac4_ops. Revert the modification in struct dwmac4_ops and re-apply it properly in struct dwmac410_ops.

[tip: x86/urgent] x86/speculation: Fix prctl() when spectre_v2_user={seccomp,prctl},ibpb

by tip-bot2 for Anand K Mistry

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: 33fc379df76b4991e5ae312f07bcd6820811971e Gitweb: https://git.kernel.org/tip/33fc379df76b4991e5ae312f07bcd6820811971e Author: Anand K Mistry <amistry(a)google.com> AuthorDate: Tue, 10 Nov 2020 12:33:53 +11:00 Committer: Borislav Petkov <bp(a)suse.de> CommitterDate: Wed, 25 Nov 2020 20:17:09 +01:00 x86/speculation: Fix prctl() when spectre_v2_user={seccomp,prctl},ibpb When spectre_v2_user={seccomp,prctl},ibpb is specified on the command line, IBPB is force-enabled and STIPB is conditionally-enabled (or not available). However, since 21998a351512 ("x86/speculation: Avoid force-disabling IBPB based on STIBP and enhanced IBRS.") the spectre_v2_user_ibpb variable is set to SPECTRE_V2_USER_{PRCTL,SECCOMP} instead of SPECTRE_V2_USER_STRICT, which is the actual behaviour. Because the issuing of IBPB relies on the switch_mm_*_ibpb static branches, the mitigations behave as expected. Since 1978b3a53a74 ("x86/speculation: Allow IBPB to be conditionally enabled on CPUs with always-on STIBP") this discrepency caused the misreporting of IB speculation via prctl(). On CPUs with STIBP always-on and spectre_v2_user=seccomp,ibpb, prctl(PR_GET_SPECULATION_CTRL) would return PR_SPEC_PRCTL | PR_SPEC_ENABLE instead of PR_SPEC_DISABLE since both IBPB and STIPB are always on. It also allowed prctl(PR_SET_SPECULATION_CTRL) to set the IB speculation mode, even though the flag is ignored. Similarly, for CPUs without SMT, prctl(PR_GET_SPECULATION_CTRL) should also return PR_SPEC_DISABLE since IBPB is always on and STIBP is not available.

[PATCH for-rc v4] IB/hfi1: Ensure correct mm is used at all times

by Dennis Dalessandro

Two earlier bug fixes have created a security problem in the hfi1 driver. One fix aimed to solve an issue where current->mm was not valid when closing the hfi1 cdev. It attempted to do this by saving a cached value of the current->mm pointer at file open time. This is a problem if another process with access to the FD calls in via write() or ioctl() to pin pages via the hfi driver. The other fix tried to solve a use after free by taking a reference on the mm. To fix this correctly we use the existing cached value of the mm in the mmu notifier. Now we can check in the insert, evict, etc. routines that current->mm matched what the notifier was registered for. If not, then don't allow access. The register of the mmu notifier will save the mm pointer. Note the check in the unregister is not needed in the event that current->mm is empty. This means the tear down is happening due to a SigKill or OOM Killer, something along those lines. If current->mm has a value then it must be checked and only the task that did the register can do the unregister. Since in do_exit() the exit_mm() is called before exit_files(), which would call our close routine a reference is needed on the mm. We rely on the mmgrab done by the registration of the notifier, whereas before it was explicit. Also of note is we do not do any explicit work to protect the interval tree notifier. It doesn't seem that this is going to be needed since we aren't actually doing anything with current->mm. The interval tree notifier stuff still has a FIXME noted from a previous commit that will be addressed in a follow on patch.

[PATCH v3 1/4] remoteproc: sysmon: Ensure remote notification ordering

by Bjorn Andersson

The reliance on the remoteproc's state for determining when to send sysmon notifications to a remote processor is racy with regard to concurrent remoteproc operations. Further more the advertisement of the state of other remote processor to a newly started remote processor might not only send the wrong state, but might result in a stream of state changes that are out of order. Address this by introducing state tracking within the sysmon instances themselves and extend the locking to ensure that the notifications are consistent with this state. Fixes: 1f36ab3f6e3b ("remoteproc: sysmon: Inform current rproc about all active rprocs") Fixes: 1877f54f75ad ("remoteproc: sysmon: Add notifications for events") Fixes: 1fb82ee806d1 ("remoteproc: qcom: Introduce sysmon") Cc: stable(a)vger.kernel.org Signed-off-by: Bjorn Andersson <bjorn.andersson(a)linaro.org> --- Changes since v2: - Hold sysmon_lock during traversal of sysmons in sysmon_start() drivers/remoteproc/qcom_sysmon.c | 25 +++++++++++++++++++++---- 1 file changed, 21 insertions(+), 4 deletions(-) diff --git a/drivers/remoteproc/qcom_sysmon.c b/drivers/remoteproc/qcom_sysmon.c index 9eb2f6bccea6..b37b111b15b3 100644 --- a/drivers/remoteproc/qcom_sysmon.c +++ b/drivers/remoteproc/qcom_sysmon.c @@ -22,6 +22,9 @@ struct qcom_sysmon { struct rproc_subdev subdev; struct rproc *rproc; + int state; + struct mutex state_lock; + struct list_head node; const char *name; @@ -448,7 +451,10 @@ static int sysmon_prepare(struct rproc_subdev *subdev) .ssr_event = SSCTL_SSR_EVENT_BEFORE_POWERUP }; + mutex_lock(&sysmon->state_lock); + sysmon->state = SSCTL_SSR_EVENT_BEFORE_POWERUP; blocking_notifier_call_chain(&sysmon_notifiers, 0, (void *)&event); + mutex_unlock(&sysmon->state_lock); return 0; } @@ -472,20 +478,25 @@ static int sysmon_start(struct rproc_subdev *subdev) .ssr_event = SSCTL_SSR_EVENT_AFTER_POWERUP }; + mutex_lock(&sysmon->state_lock); + sysmon->state = SSCTL_SSR_EVENT_AFTER_POWERUP; blocking_notifier_call_chain(&sysmon_notifiers, 0, (void *)&event); + mutex_unlock(&sysmon->state_lock); mutex_lock(&sysmon_lock); list_for_each_entry(target, &sysmon_list, node) { - if (target == sysmon || - target->rproc->state != RPROC_RUNNING) + if (target == sysmon) continue; + mutex_lock(&target->state_lock); event.subsys_name = target->name; + event.ssr_event = target->state; if (sysmon->ssctl_version == 2) ssctl_send_event(sysmon, &event); else if (sysmon->ept) sysmon_send_event(sysmon, &event); + mutex_unlock(&target->state_lock); } mutex_unlock(&sysmon_lock); @@ -500,7 +511,10 @@ static void sysmon_stop(struct rproc_subdev *subdev, bool crashed) .ssr_event = SSCTL_SSR_EVENT_BEFORE_SHUTDOWN }; + mutex_lock(&sysmon->state_lock); + sysmon->state = SSCTL_SSR_EVENT_BEFORE_SHUTDOWN; blocking_notifier_call_chain(&sysmon_notifiers, 0, (void *)&event); + mutex_unlock(&sysmon->state_lock); /* Don't request graceful shutdown if we've crashed */ if (crashed) @@ -521,7 +535,10 @@ static void sysmon_unprepare(struct rproc_subdev *subdev) .ssr_event = SSCTL_SSR_EVENT_AFTER_SHUTDOWN }; + mutex_lock(&sysmon->state_lock); + sysmon->state = SSCTL_SSR_EVENT_AFTER_SHUTDOWN; blocking_notifier_call_chain(&sysmon_notifiers, 0, (void *)&event); + mutex_unlock(&sysmon->state_lock); } /** @@ -534,11 +551,10 @@ static int sysmon_notify(struct notifier_block *nb, unsigned long event, void *data) { struct qcom_sysmon *sysmon = container_of(nb, struct qcom_sysmon, nb); - struct rproc *rproc = sysmon->rproc; struct sysmon_event *sysmon_event = data; /* Skip non-running rprocs and the originating instance */ - if (rproc->state != RPROC_RUNNING || + if (sysmon->state != SSCTL_SSR_EVENT_AFTER_POWERUP || !strcmp(sysmon_event->subsys_name, sysmon->name)) { dev_dbg(sysmon->dev, "not notifying %s\n", sysmon->name); return NOTIFY_DONE; @@ -591,6 +607,7 @@ struct qcom_sysmon *qcom_add_sysmon_subdev(struct rproc *rproc, init_completion(&sysmon->ind_comp); init_completion(&sysmon->shutdown_comp); mutex_init(&sysmon->lock); + mutex_init(&sysmon->state_lock); sysmon->shutdown_irq = of_irq_get_byname(sysmon->dev->of_node, "shutdown-ack"); -- 2.28.0
