[PATCH OLK-5.10] media: dvb-core: Fix use-after-free due to race condition at dvb_ca_en50221
by Peng Zhang 26 Oct '23

26 Oct '23

From: Hyunwoo Kim <v4bel(a)theori.io> mainline inclusion from mainline-v6.4-rc3 commit 280a8ab81733da8bc442253c700a52c4c0886ffd category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I63D3C CVE: CVE-2022-45919 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------- If the device node of dvb_ca_en50221 is open() and the device is disconnected, a UAF may occur when calling close() on the device node. The root cause is that wake_up() and wait_event() for dvbdev->wait_queue are not implemented. So implement wait_event() function in dvb_ca_en50221_release() and add 'remove_mutex' which prevents race condition for 'ca->exit'.

[PATCH OLK-5.10] xen/events: replace evtchn_rwlock with RCU
by Liu Shixin 26 Oct '23

26 Oct '23

From: Juergen Gross <jgross(a)suse.com> stable inclusion from stable-v5.10.198 commit 660627c71bc1098aa94e5f208f14748b105b73bc category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I896EC CVE: CVE-2023-34324 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 87797fad6cce28ec9be3c13f031776ff4f104cfc upstream. In unprivileged Xen guests event handling can cause a deadlock with Xen console handling. The evtchn_rwlock and the hvc_lock are taken in opposite sequence in __hvc_poll() and in Xen console IRQ handling. Normally this is no problem, as the evtchn_rwlock is taken as a reader in both paths, but as soon as an event channel is being closed, the lock will be taken as a writer, which will cause read_lock() to block: CPU0 CPU1 CPU2 (IRQ handling) (__hvc_poll()) (closing event channel) read_lock(evtchn_rwlock) spin_lock(hvc_lock) write_lock(evtchn_rwlock) [blocks] spin_lock(hvc_lock) [blocks] read_lock(evtchn_rwlock) [blocks due to writer waiting, and not in_interrupt()] This issue can be avoided by replacing evtchn_rwlock with RCU in xen_free_irq(). Note that RCU is used only to delay freeing of the irq_info memory. There is no RCU based dereferencing or replacement of pointers involved. In order to avoid potential races between removing the irq_info reference and handling of interrupts, set the irq_info pointer to NULL only when freeing its memory. The IRQ itself must be freed at that time, too, as otherwise the same IRQ number could be allocated again before handling of the old instance would have been finished. This is XSA-441 / CVE-2023-34324.

[PATCH openEuler-1.0-LTS] xen/events: replace evtchn_rwlock with RCU
by Liu Shixin 25 Oct '23

25 Oct '23

From: Juergen Gross <jgross(a)suse.com> stable inclusion from stable-v4.19.296 commit 3fdf2be9089b5096a28e76376656c60ce410ac4a category: bugfix bugzilla: 189304, https://gitee.com/src-openeuler/kernel/issues/I896EC CVE: CVE-2023-34324 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 87797fad6cce28ec9be3c13f031776ff4f104cfc upstream. In unprivileged Xen guests event handling can cause a deadlock with Xen console handling. The evtchn_rwlock and the hvc_lock are taken in opposite sequence in __hvc_poll() and in Xen console IRQ handling. Normally this is no problem, as the evtchn_rwlock is taken as a reader in both paths, but as soon as an event channel is being closed, the lock will be taken as a writer, which will cause read_lock() to block: CPU0 CPU1 CPU2 (IRQ handling) (__hvc_poll()) (closing event channel) read_lock(evtchn_rwlock) spin_lock(hvc_lock) write_lock(evtchn_rwlock) [blocks] spin_lock(hvc_lock) [blocks] read_lock(evtchn_rwlock) [blocks due to writer waiting, and not in_interrupt()] This issue can be avoided by replacing evtchn_rwlock with RCU in xen_free_irq(). Note that RCU is used only to delay freeing of the irq_info memory. There is no RCU based dereferencing or replacement of pointers involved. In order to avoid potential races between removing the irq_info reference and handling of interrupts, set the irq_info pointer to NULL only when freeing its memory. The IRQ itself must be freed at that time, too, as otherwise the same IRQ number could be allocated again before handling of the old instance would have been finished.

[openEuler/rdma-core] libhns: Support flexible WQE buffer page size
by Chengchang Tang 23 Oct '23

23 Oct '23

driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I87LTM -------------------------------------------------------------------------- Currently, driver fixedly allocates 4K pages for user space WQE buffer even in a 64K system. This results in HW reading WQE with a granularity of 4K even in a 64K system. Considering that we support 1024-byte inline, in the scenario of using SQ inline, HW will switch pages every 4 WQEs. This will introduce a delay of about 400ns, which is an average delay of 100ns per packet. In order to improve performance, we allow user-mode drivers to use a larger page size to allocate WQE buffers, thereby reducing the latency introduced by HW page switching. User-mode drivers will be allowed to allocate WQE buffers between 4K to system page size. During ibv_create_qp(), the driver will dynamically select the appropriate page size based on ibv_qp_cap, thus reducing memory consumption while improving performance. This feature needs to be used in conjunction with the kernel-mode driver. In order to ensure forward compatibility, if the kernel-mode driver does not support this feature, the user-mode driver will continue to use a fixed 4K pagesize to allocate WQE buffer.

[PATCH OLK-5.10] scsi: mpt3sas: Perform additional retries if doorbell read returns 0
by Hao Zhang 23 Oct '23

23 Oct '23

From: Ranjan Kumar <ranjan.kumar(a)broadcom.com> stable inclusion from stable-v5.10.195 commit ffed0c8fcf043946f2bf09bd2a9caa1ca5289959 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I868SX CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 4ca10f3e31745d35249a727ecd108eb58f0a8c5e upstream. The driver retries certain register reads 3 times if the returned value is 0. This was done because the controller could return 0 for certain registers if other registers were being accessed concurrently by the BMC. In certain systems with increased BMC interactions, the register values returned can be 0 for longer than 3 retries. Change the retry count from 3 to 30 for the affected registers to prevent problems with out-of-band management.

From: James Clark <james.clark(a)arm.com> mainline inclusion from mainline-v6.4-rc1 commit c45b2835e7b205783bdfe08cc98fa86a7c5eeb74 category: Bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I89FF2 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------------------------------------------------------- child_fwnode should be a read only property based on the DT or ACPI. If it's cleared on the parent device when a child is unloaded, then when the child is loaded again the connection won't be remade. child_dev should be cleared instead which signifies that the connection should be remade when the child_fwnode registers a new coresight_device. Similarly the reference count shouldn't be decremented as long as the parent device exists. The correct place to drop the reference is in coresight_release_platform_data() which is already done. Reproducible on Juno with the following steps: # load all coresight modules. $ cd /sys/bus/coresight/devices/ $ echo 1 > tmc_etr0/enable_sink $ echo 1 > etm0/enable_source # Works fine ^ $ echo 0 > etm0/enable_source $ rmmod coresight-funnel $ modprobe coresight-funnel $ echo 1 > etm0/enable_source -bash: echo: write error: Invalid argument Fixes: 37ea1ffddffa ("coresight: Use fwnode handle instead of device names") Fixes: 2af89ebacf29 ("coresight: Clear the connection field properly") Tested-by: Suzuki K Poulose <suzuki.poulose(a)arm.com> Reviewed-by: Mike Leach <mike.leach(a)linaro.org> Signed-off-by: James Clark <james.clark(a)arm.com> Signed-off-by: Suzuki K Poulose <suzuki.poulose(a)arm.com> Link: https://lore.kernel.org/r/20230425143542.2305069-2-james.clark@arm.com Signed-off-by: Junhao He <hejunhao3(a)huawei.com> --- drivers/hwtracing/coresight/coresight-core.c | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) diff --git a/drivers/hwtracing/coresight/coresight-core.c b/drivers/hwtracing/coresight/coresight-core.c index ee7b5cfcf786..9696f402a328 100644 --- a/drivers/hwtracing/coresight/coresight-core.c +++ b/drivers/hwtracing/coresight/coresight-core.c @@ -1443,13 +1443,8 @@ static int coresight_remove_match(struct device *dev, void *data) if (csdev->dev.fwnode == conn->child_fwnode) { iterator->orphan = true; coresight_remove_links(iterator, conn); - /* - * Drop the reference to the handle for the remote - * device acquired in parsing the connections from - * platform data. - */ - fwnode_handle_put(conn->child_fwnode); - conn->child_fwnode = NULL; + + conn->child_dev = NULL; /* No need to continue */ break; } -- 2.33.0

[PATCH OLK-5.10] coresight: Fix loss of connection info when a module is unloaded
by Junhao He 18 Oct '23

18 Oct '23

From: James Clark <james.clark(a)arm.com> mainline inclusion from mainline-v6.4-rc1 commit c45b2835e7b205783bdfe08cc98fa86a7c5eeb74 category: Bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I85PIL CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------------------------------------------------------- child_fwnode should be a read only property based on the DT or ACPI. If it's cleared on the parent device when a child is unloaded, then when the child is loaded again the connection won't be remade. child_dev should be cleared instead which signifies that the connection should be remade when the child_fwnode registers a new coresight_device. Similarly the reference count shouldn't be decremented as long as the parent device exists. The correct place to drop the reference is in coresight_release_platform_data() which is already done. Reproducible on Juno with the following steps: # load all coresight modules. $ cd /sys/bus/coresight/devices/ $ echo 1 > tmc_etr0/enable_sink $ echo 1 > etm0/enable_source # Works fine ^ $ echo 0 > etm0/enable_source $ rmmod coresight-funnel $ modprobe coresight-funnel $ echo 1 > etm0/enable_source -bash: echo: write error: Invalid argument Fixes: 37ea1ffddffa ("coresight: Use fwnode handle instead of device names") Fixes: 2af89ebacf29 ("coresight: Clear the connection field properly") Tested-by: Suzuki K Poulose <suzuki.poulose(a)arm.com> Reviewed-by: Mike Leach <mike.leach(a)linaro.org> Signed-off-by: James Clark <james.clark(a)arm.com> Signed-off-by: Suzuki K Poulose <suzuki.poulose(a)arm.com> Link: https://lore.kernel.org/r/20230425143542.2305069-2-james.clark@arm.com Signed-off-by: Junhao He <hejunhao3(a)huawei.com> --- drivers/hwtracing/coresight/coresight-core.c | 9 ++------- 1 file changed, 2 insertions(+), 7 deletions(-) diff --git a/drivers/hwtracing/coresight/coresight-core.c b/drivers/hwtracing/coresight/coresight-core.c index ee7b5cfcf786..9696f402a328 100644 --- a/drivers/hwtracing/coresight/coresight-core.c +++ b/drivers/hwtracing/coresight/coresight-core.c @@ -1443,13 +1443,8 @@ static int coresight_remove_match(struct device *dev, void *data) if (csdev->dev.fwnode == conn->child_fwnode) { iterator->orphan = true; coresight_remove_links(iterator, conn); - /* - * Drop the reference to the handle for the remote - * device acquired in parsing the connections from - * platform data. - */ - fwnode_handle_put(conn->child_fwnode); - conn->child_fwnode = NULL; + + conn->child_dev = NULL; /* No need to continue */ break; } -- 2.33.0
