[PATCH v2 1/3] libata: fix reading concurrent positioning ranges log

by Tyler Erickson

The concurrent positioning ranges log is not a fixed size and may depend on how many ranges are supported by the device. This patch uses the size reported in the GPL directory to determine the number of pages supported by the device before attempting to read this log page. This resolves this error from the dmesg output: ata6.00: Read log 0x47 page 0x00 failed, Emask 0x1 Cc: stable(a)vger.kernel.org Fixes: fe22e1c2f705 ("libata: support concurrent positioning ranges log") Signed-off-by: Tyler Erickson <tyler.erickson(a)seagate.com> Reviewed-by: Muhammad Ahmad <muhammad.ahmad(a)seagate.com> Tested-by: Michael English <michael.english(a)seagate.com> --- drivers/ata/libata-core.c | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c index 40e816419f48..3ea10f72cb70 100644 --- a/drivers/ata/libata-core.c +++ b/drivers/ata/libata-core.c @@ -2010,16 +2010,16 @@ unsigned int ata_read_log_page(struct ata_device *dev, u8 log, return err_mask; } -static bool ata_log_supported(struct ata_device *dev, u8 log) +static int ata_log_supported(struct ata_device *dev, u8 log) { struct ata_port *ap = dev->link->ap; if (dev->horkage & ATA_HORKAGE_NO_LOG_DIR) - return false; + return 0; if (ata_read_log_page(dev, ATA_LOG_DIRECTORY, 0, ap->sector_buf, 1)) - return false; - return get_unaligned_le16(&ap->sector_buf[log * 2]) ? true : false; + return 0; + return get_unaligned_le16(&ap->sector_buf[log * 2]); } static bool ata_identify_page_supported(struct ata_device *dev, u8 page) @@ -2455,15 +2455,20 @@ static void ata_dev_config_cpr(struct ata_device *dev) struct ata_cpr_log *cpr_log = NULL; u8 *desc, *buf = NULL; - if (ata_id_major_version(dev->id) < 11 || - !ata_log_supported(dev, ATA_LOG_CONCURRENT_POSITIONING_RANGES)) + if (ata_id_major_version(dev->id) < 11) + goto out; + + buf_len = ata_log_supported(dev, ATA_LOG_CONCURRENT_POSITIONING_RANGES); + if (buf_len == 0) goto out; /* * Read the concurrent positioning ranges log (0x47).

[PATCH] ARM: initialize jump labels before setup_machine_fdt()

by Jason A. Donenfeld

Stephen reported that a static key warning splat appears during early boot on arm64 systems that credit randomness from device trees that contain an "rng-seed" property, because setup_machine_fdt() is called before jump_label_init() during setup_arch(), which was fixed by 73e2d827a501 ("arm64: Initialize jump labels before setup_machine_fdt()"). Upon cursory inspection, the same basic issue appears to apply to arm32 as well. In this case, we reorder setup_arch() to do things in the same order as is now the case on arm64.

[PATCH v2 2/3] libata: fix translation of concurrent positioning ranges

by Tyler Erickson

Dearest beloved in the Lord,

by agnesgeorge

Dearest beloved in the Lord, I am Ms. Agnes George, a 75 year old British woman. I was born an orphan and GOD blessed me abundantly with riches but no children nor husband which makes me an unhappy woman. Now I am affected with cancer of the lung and breast with a partial stroke which has affected my speech. I can no longer talk well and half of my body is paralyzed, I sent this email to you with the help of my private female nurse. My condition is really deteriorating day by day and it is really giving me lots to think about. This has prompted my decision to donate all I have for charity; I have made numerous donations all over the world. After going through your profile, I decided to make my last donation of Ten Million Five Hundred Thousand United Kingdom Pounds (UK£10.500, 000, 00) to you as my investment manager. I want you to build an Orphanage home with my name ( Agnes George ) in your country. If you are willing and able to do this task for the sake of humanity then send me below information for more details to receive the funds. 1. Name................................................... 2. Phone number............................... 3. Address............................................. 4. Country of Origin and residence Ms. Agnes George.

[PATCH 2/3] drm/display/dp_mst: Fix drm_atomic_get_mst_topology_state()

by Lyude Paul

I noticed a rather surprising issue here while working on removing all of the non-atomic MST code: drm_atomic_get_mst_topology_state() doesn't check the return value of drm_atomic_get_private_obj_state() and instead just passes it directly to to_dp_mst_topology_state(). This means that if we hit a deadlock or something else which would return an error code pointer, we'll likely segfault the kernel. This is definitely another one of those fixes where I'm astonished we somehow managed never to discover this issue until now… Signed-off-by: Lyude Paul <lyude(a)redhat.com> Fixes: a4370c777406 ("drm/atomic: Make private objs proper objects") Cc: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Cc: <stable(a)vger.kernel.org> # v4.14+ --- drivers/gpu/drm/display/drm_dp_mst_topology.c | 2 +- include/drm/display/drm_dp_mst_helper.h | 2 ++ 2 files changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/display/drm_dp_mst_topology.c b/drivers/gpu/drm/display/drm_dp_mst_topology.c index d84673b3294b..d6e595b95f07 100644 --- a/drivers/gpu/drm/display/drm_dp_mst_topology.c +++ b/drivers/gpu/drm/display/drm_dp_mst_topology.c @@ -5468,7 +5468,7 @@ EXPORT_SYMBOL(drm_dp_mst_topology_state_funcs); struct drm_dp_mst_topology_state *drm_atomic_get_mst_topology_state(struct drm_atomic_state *state, struct drm_dp_mst_topology_mgr *mgr) { - return to_dp_mst_topology_state(drm_atomic_get_private_obj_state(state, &mgr->base)); + return to_dp_mst_topology_state_safe(drm_atomic_get_private_obj_state(state, &mgr->base)); } EXPORT_SYMBOL(drm_atomic_get_mst_topology_state); diff --git a/include/drm/display/drm_dp_mst_helper.h b/include/drm/display/drm_dp_mst_helper.h index 10adec068b7f..fe7577e7f305 100644 --- a/include/drm/display/drm_dp_mst_helper.h +++ b/include/drm/display/drm_dp_mst_helper.h @@ -541,6 +541,8 @@ struct drm_dp_payload { }; #define to_dp_mst_topology_state(x) container_of(x, struct drm_dp_mst_topology_state, base) +#define to_dp_mst_topology_state_safe(x) \ + container_of_safe(x, struct drm_dp_mst_topology_state, base) struct drm_dp_vcpi_allocation { struct drm_dp_mst_port *port; -- 2.35.3

[PATCH stable 5.10.y 0/5] missing random.c-related stable patches

by Jason A. Donenfeld

Hi Greg, I forgot two things when doing the 5.10 backport. The first is a patch from Justin fixing a bug in some of the lib/crypto Kconfig changes, which Pablo (CC'd) pointed out was missed. The second is that the backport of 5acd35487dc9 ("random: replace custom notifier chain with standard one") isn't quite right without Nicolai's patches there too, since the drbg module is removable. I'll continue to monitor all the channels I possibly can for chatter about problems, but so far this is all I've run into. Jason Cc: Pablo Greco <pgreco(a)centosproject.org> Justin M.

[PATCH v3] x86/sgx: Set active memcg prior to shmem allocation

by Kristen Carlson Accardi

When the system runs out of enclave memory, SGX can reclaim EPC pages by swapping to normal RAM. These backing pages are allocated via a per-enclave shared memory area. Since SGX allows unlimited over commit on EPC memory, the reclaimer thread can allocate a large number of backing RAM pages in response to EPC memory pressure. When the shared memory backing RAM allocation occurs during the reclaimer thread context, the shared memory is charged to the root memory control group, and the shmem usage of the enclave is not properly accounted for, making cgroups ineffective at limiting the amount of RAM an enclave can consume. For example, when using a cgroup to launch a set of test enclaves, the kernel does not properly account for 50% - 75% of shmem page allocations on average. In the worst case, when nearly all allocations occur during the reclaimer thread, the kernel accounts less than a percent of the amount of shmem used by the enclave's cgroup to the correct cgroup. SGX stores a list of mm_structs that are associated with an enclave. Pick one of them during reclaim and charge that mm's memcg with the shmem allocation. The one that gets picked is arbitrary, but this list almost always only has one mm. The cases where there is more than one mm with different memcg's are not worth considering. Create a new function - sgx_encl_alloc_backing(). This function is used whenever a new backing storage page needs to be allocated. Previously the same function was used for page allocation as well as retrieving a previously allocated page. Prior to backing page allocation, if there is a mm_struct associated with the enclave that is requesting the allocation, it is set as the active memory control group. Signed-off-by: Kristen Carlson Accardi <kristen(a)linux.intel.com> Reviewed-by: Shakeel Butt <shakeelb(a)google.com> Acked-by: Roman Gushchin <roman.gushchin(a)linux.dev> Cc: stable(a)vger.kernel.org --- V2 -> V3: Changed memcg variable names in sgx_encl_alloc_backing() and removed some whitespace. V1 -> V2: Changed sgx_encl_set_active_memcg() to simply return the correct memcg for the enclave and renamed to sgx_encl_get_mem_cgroup(). Created helper function current_is_ksgxd() to improve readability. Use mmget_not_zero()/mmput_async() when searching mm_list. Move call to set_active_memcg() to sgx_encl_alloc_backing() and use mem_cgroup_put() to avoid leaking a memcg reference.
