2023-06-01rtnetlink: call validate_linkmsg in rtnl_create_linkXin Long1-1/+7
validate_linkmsg() was introduced by commit 1840bb13c22f5b ("[RTNL]: Validate hardware and broadcast address attribute for RTM_NEWLINK") to validate tb[IFLA_ADDRESS/BROADCAST] for existing links. The same check should also be done for newly created links. This patch adds validate_linkmsg() call in rtnl_create_link(), to avoid the invalid address set when creating some devices like: # ip link add dummy0 type dummy # ip link add link dummy0 name mac0 address 01:02 type macsec Fixes: 0e06877c6fdb ("[RTNETLINK]: rtnl_link: allow specifying initial device address") Signed-off-by: Xin Long <[email protected]> Reviewed-by: Simon Horman <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>
2023-06-01ice: recycle/free all of the fragments from multi-buffer frameMaciej Fijalkowski1-1/+1
The ice driver caches next_to_clean value at the beginning of ice_clean_rx_irq() in order to remember the first buffer that has to be freed/recycled after main Rx processing loop. The end boundary is indicated by first descriptor of frame that Rx processing loop has ended its duties. Note that if mentioned loop ended in the middle of gathering multi-buffer frame, next_to_clean would be pointing to the descriptor in the middle of the frame BUT freeing/recycling stage will stop at the first descriptor. This means that next iteration of ice_clean_rx_irq() will miss the (first_desc, next_to_clean - 1) entries.

By changing the NAND frequency select without reflecting this in the clock configuration this means that the timings calculated don't correctly meet the requirements of the NAND chip.

2023-06-01net: dsa: mv88e6xxx: Increase wait after reset deactivationAndreas Svensson1-1/+1
A switch held in reset by default needs to wait longer until we can reliably detect it. An issue was observed when testing on the Marvell 88E6393X (Link Street). The driver failed to detect the switch on some upstarts. Increasing the wait time after reset deactivation solves this issue. The updated wait time is now also the same as the wait time in the mv88e6xxx_hardware_reset function.

2023-06-01btrfs: zoned: fix dev-replace after the scrub reworkQu Wenruo2-20/+32
[BUG] After commit e02ee89baa66 ("btrfs: scrub: switch scrub_simple_mirror() to scrub_stripe infrastructure"), scrub no longer works for zoned device at all. Even an empty zoned btrfs cannot be replaced: # mkfs.btrfs -f /dev/nvme0n1 # mount /dev/nvme0n1 /mnt/btrfs # btrfs replace start -Bf 1 /dev/nvme0n2 /mnt/btrfs Resetting device zones /dev/nvme1n1 (160 zones) ...

And for zoned devices, we call fill_writer_pointer_gap() to make sure all the writes into the zoned device is sequential, even if there may be some gaps between the writes. However we have several different bugs all related to zoned dev-replace: - We are using ZONE_APPEND operation for metadata style write back For zoned devices, btrfs has two ways to write data: * ZONE_APPEND for data This allows higher queue depth, but will not be able to know where the write would land. Thus needs to grab the real on-disk physical location in it's endio. * WRITE for metadata This requires single queue depth (new writes can only be submitted after previous one finished), and all writes must be sequential. For scrub, we go single queue depth, but still goes with ZONE_APPEND, which requires btrfs_bio::inode being populated. This is the cause of that crash. - No correct tracing of write_pointer After a write finished, we should forward sctx->write_pointer, or fill_writer_pointer_gap() would not work properly and cause more than necessary zero out, and fill the whole zone prematurely. - Incorrect physical bytenr passed to fill_writer_pointer_gap() In scrub_write_sectors(), one call site passes logical address, which is completely wrong. The other call site passes physical address of current sector, but we should pass the physical address of the btrfs_bio we're submitting. This is the cause of the -EIO errors. [FIX] - Do not use ZONE_APPEND for btrfs_submit_repair_write(). - Manually forward sctx->write_pointer after successful writeback - Use the physical address of the to-be-submitted btrfs_bio for fill_writer_pointer_gap() Now zoned device replace would work as expected.

2023-06-01tcp: fix mishandling when the sack compression is deferred.fuyuanli3-4/+15
In this patch, we mainly try to handle sending a compressed ack correctly if it's deferred. Here are more details in the old logic: When sack compression is triggered in the tcp_compressed_ack_kick(), if the sock is owned by user, it will set TCP_DELACK_TIMER_DEFERRED and then defer to the release cb phrase. Later once user releases the sock, tcp_delack_timer_handler() should send a ack as expected, which, however, cannot happen due to lack of ICSK_ACK_TIMER flag. Therefore, the receiver would not sent an ack until the sender's retransmission timeout. It definitely increases unnecessary latency.

Failure ladders weren't exactly unwinding what the function had done up to that point; most seriously, when we encountered an already offloaded rule, the failure path tried to remove the new rule from the hashtable, which would in fact remove the already-present 'old' rule (since it has the same key) from the table, and leak its resources.

2023-05-31net/mlx5: Fix setting of irq->map.index for static IRQ caseNiklas Schnelle1-4/+5
When dynamic IRQ allocation is not supported all IRQs are allocated up front in mlx5_irq_table_create() instead of dynamically as part of mlx5_irq_alloc(). In the latter dynamic case irq->map.index is set via the mapping returned by pci_msix_alloc_irq_at(). In the static case and prior to commit 1da438c0ae02 ("net/mlx5: Fix indexing of mlx5_irq") irq->map.index was set in mlx5_irq_alloc() twice once initially to 0 and then to the requested index before storing in the xarray. After this commit it is only set to 0 which breaks all other IRQ mappings. Fix this by setting irq->map.index to the requested index together with irq->map.virq and improve the related comment to make it clearer which cases it deals with.

2023-05-31net/mlx5: Remove rmap also in case dynamic MSIX not supportedShay Drory1-1/+1
mlx5 add IRQs to rmap upon MSIX request, and mlx5 remove rmap from MSIX only if msi_map.index is populated. However, msi_map.index is populated only when dynamic MSIX is supported. This results in freeing IRQs without removing them from rmap, which triggers the bellow WARN_ON[1]. rmap is a feature which have no relation to dynamic MSIX. Hence, remove the check of msi_map.index when removing IRQ from rmap.

2023-05-31drivers: base: cacheinfo: Update cpu_map_populated during CPU HotplugK Prateek Nayak1-0/+6
Until commit 5c2712387d48 ("cacheinfo: Fix LLC is not exported through sysfs"), cacheinfo called populate_cache_leaves() for CPU coming online which let the arch specific functions handle (at least on x86) populating the shared_cpu_map. However, with the changes in the aforementioned commit, populate_cache_leaves() is not called when a CPU comes online as a result of hotplug since last_level_cache_is_valid() returns true as the cacheinfo data is not discarded. The CPU coming online is not present in shared_cpu_map, however, it will not be added since the cpu_cacheinfo->cpu_map_populated flag is set (it is set in populate_cache_leaves() when cacheinfo is first populated for x86) This can lead to inconsistencies in the shared_cpu_map when an offlined CPU comes online again. Example below depicts the inconsistency in the shared_cpu_list in cacheinfo when CPU8 is offlined and onlined again on a 3rd Generation EPYC processor: # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143 # echo 0 > /sys/devices/system/cpu/cpu8/online # echo 1 > /sys/devices/system/cpu/cpu8/online # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8 # cat /sys/devices/system/cpu/cpu136/cache/index0/shared_cpu_list 136 # cat /sys/devices/system/cpu/cpu136/cache/index3/shared_cpu_list 9-15,136-143 Clear the flag when the CPU is removed from shared_cpu_map when cache_shared_cpu_map_remove() is called during CPU hotplug. This will allow cache_shared_cpu_map_setup() to add the CPU coming back online in the shared_cpu_map. Set the flag again when the shared_cpu_map is setup. Following are results of performing the same test as described above with the changes: # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143 # echo 0 > /sys/devices/system/cpu/cpu8/online # echo 1 > /sys/devices/system/cpu/cpu8/online # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143 # cat /sys/devices/system/cpu/cpu136/cache/index0/shared_cpu_list 8,136 # cat /sys/devices/system/cpu/cpu136/cache/index3/shared_cpu_list 8-15,136-143 Fixes: 5c2712387d48 ("cacheinfo: Fix LLC is not exported through sysfs") Signed-off-by: K Prateek Nayak <[email protected]> Reviewed-by: Yicong Yang <[email protected]> Reviewed-by: Sudeep Holla <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
2023-05-31drivers: base: cacheinfo: Fix shared_cpu_map changes in event of CPU hotplugK Prateek Nayak1-0/+20
While building the shared_cpu_map, check if the cache level and cache type matches. On certain systems that build the cache topology based on the instance ID, there are cases where the same ID may repeat across multiple cache levels, leading inaccurate topology. In event of CPU offlining, the cache_shared_cpu_map_remove() does not consider if IDs at same level are being compared. As a result, when same IDs repeat across different cache levels, the CPU going offline is not removed from all the shared_cpu_map. Below is the output of cache topology of CPU8 and it's SMT sibling after CPU8 is offlined on a dual socket 3rd Generation AMD EPYC processor (2 x 64C/128T) running kernel release v6.3: # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143 # echo 0 > /sys/devices/system/cpu/cpu8/online # for i in /sys/devices/system/cpu/cpu136/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu136/cache/index0/shared_cpu_list: 136 /sys/devices/system/cpu/cpu136/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu136/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu136/cache/index3/shared_cpu_list: 9-15,136-143 CPU8 is removed from index0 (L1i) but remains in the shared_cpu_list of index1 (L1d) and index2 (L2). Since L1i, L1d, and L2 are shared by the SMT siblings, and they have the same cache instance ID, CPU 2 is only removed from the first index with matching ID which is index1 (L1i) in this case. With this fix, the results are as expected when performing the same experiment on the same system: # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136 /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143 # echo 0 > /sys/devices/system/cpu/cpu8/online # for i in /sys/devices/system/cpu/cpu136/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done /sys/devices/system/cpu/cpu136/cache/index0/shared_cpu_list: 136 /sys/devices/system/cpu/cpu136/cache/index1/shared_cpu_list: 136 /sys/devices/system/cpu/cpu136/cache/index2/shared_cpu_list: 136 /sys/devices/system/cpu/cpu136/cache/index3/shared_cpu_list: 9-15,136-143 When rebuilding topology, the same problem appears as cache_shared_cpu_map_setup() implements a similar logic. Consider the same 3rd Generation EPYC processor: CPUs in Core 1, that share the L1 and L2 caches, have L1 and L2 instance ID as 1. For all the CPUs on the second chiplet, the L3 ID is also 1 leading to grouping on CPUs from Core 1 (1, 17) and the entire second chiplet (8-15, 24-31) as CPUs sharing one cache domain. This went undetected since x86 processors depended on arch specific populate_cache_leaves() method to repopulate the shared_cpus_map when CPU came back online until kernel release v6.3-rc5.

2023-05-31test_firmware: prevent race conditions by a correct implementation of lockingMirsad Goran Todorovac1-17/+35
Dan Carpenter spotted a race condition in a couple of situations like these in the test_firmware driver: static int test_dev_config_update_u8(const char *buf, size_t size, u8 *cfg) { u8 val; int ret; ret = kstrtou8(buf, 10, &val); if (ret) return ret; mutex_lock(&test_fw_mutex); *(u8 *)cfg = val; mutex_unlock(&test_fw_mutex); /* Always return full write size even if we didn't consume all */ return size; } static ssize_t config_num_requests_store(struct device *dev, struct device_attribute *attr, const char *buf, size_t count) { int rc; mutex_lock(&test_fw_mutex); if (test_fw_config->reqs) { pr_err("Must call release_all_firmware prior to changing config\n"); rc = -EINVAL; mutex_unlock(&test_fw_mutex); goto out; } mutex_unlock(&test_fw_mutex); rc = test_dev_config_update_u8(buf, count, &test_fw_config->num_requests); out: return rc; } static ssize_t config_read_fw_idx_store(struct device *dev, struct device_attribute *attr, const char *buf, size_t count) { return test_dev_config_update_u8(buf, count, &test_fw_config->read_fw_idx); } The function test_dev_config_update_u8() is called from both the locked and the unlocked context, function config_num_requests_store() and config_read_fw_idx_store() which can both be called asynchronously as they are driver's methods, while test_dev_config_update_u8() and siblings change their argument pointed to by u8 *cfg or similar pointer. To avoid deadlock on test_fw_mutex, the lock is dropped before calling test_dev_config_update_u8() and re-acquired within test_dev_config_update_u8() itself, but alas this creates a race condition. Having two locks wouldn't assure a race-proof mutual exclusion. This situation is best avoided by the introduction of a new, unlocked function __test_dev_config_update_u8() which can be called from the locked context and reducing test_dev_config_update_u8() to: static int test_dev_config_update_u8(const char *buf, size_t size, u8 *cfg) { int ret; mutex_lock(&test_fw_mutex); ret = __test_dev_config_update_u8(buf, size, cfg); mutex_unlock(&test_fw_mutex); return ret; } doing the locking and calling the unlocked primitive, which enables both locked and unlocked versions without duplication of code. The similar approach was applied to all functions called from the locked and the unlocked context, which safely mitigates both deadlocks and race conditions in the driver. __test_dev_config_update_bool(), __test_dev_config_update_u8() and __test_dev_config_update_size_t() unlocked versions of the functions were introduced to be called from the locked contexts as a workaround without releasing the main driver's lock and thereof causing a race condition. The test_dev_config_update_bool(), test_dev_config_update_u8() and test_dev_config_update_size_t() locked versions of the functions are being called from driver methods without the unnecessary multiplying of the locking and unlocking code for each method, and complicating the code with saving of the return value across lock.
