Vladimir Oltean says: ==================== Regressions in Ocelot switch drivers These are 3 patches which resolve a regression in the Seville driver, one in the Felix driver and a generic one which affects any kernel compiled with 2 Kconfig options enabled. All of them have in common my lack of attention during review/testing. The patches touch the DSA, MFD and MDIO drivers for Ocelot. I think it would be preferable if all patches went through netdev (with Lee's Ack). ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

When compiling a kernel which has both CONFIG_NET_DSA_MSCC_OCELOT_EXT and CONFIG_MSCC_OCELOT_SWITCH enabled, the following error message will be printed: [ 5.266588] Error: Driver 'ocelot-switch' is already registered, aborting... Rename the ocelot_ext.c driver to "ocelot-ext-switch" to avoid the name duplication, and update the mfd_cell entry for its resources.

The blamed commit did not properly convert the resource start/end format into the DEFINE_RES_MEM_NAMED() start/length format, resulting in a resource for vsc9959_imdio_res which is much longer than expected: $ cat /proc/iomem 1f8000000-1f815ffff : pcie@1f0000000 1f8140000-1f815ffff : 0000:00:00.5 1f8148030-1f815006f : imdio vs (correct) $ cat /proc/iomem 1f8000000-1f815ffff : pcie@1f0000000 1f8140000-1f815ffff : 0000:00:00.5 1f8148030-1f814803f : imdio Luckily it's not big enough to exceed the size of the parent resource (pci_resource_end(pdev, VSC9959_IMDIO_PCI_BAR)), and it doesn't overlap with anything else that the Linux driver uses currently, so the larger than expected size isn't a practical problem that I can see. Although it is clearly wrong in the /proc/iomem output. Fixes: 044d447a ("net: dsa: felix: use DEFINE_RES_MEM_NAMED for resources") Signed-off-by: -

During the refactoring in the commit below, vsc9953_mdio_read() was replaced with mscc_miim_read(), which has one extra step: it checks for the MSCC_MIIM_DATA_ERROR bits before returning the result. On T1040RDB, there are 8 QSGMII PCSes belonging to the switch, and they are organized in 2 groups. First group responds to MDIO addresses 4-7 because QSGMIIACR1[MDEV_PORT] is 1, and the second group responds to MDIO addresses 8-11 because QSGMIIBCR1[MDEV_PORT] is 2. I have double checked that these values are correctly set in the SERDES, as well as PCCR1[QSGMA_CFG] and PCCR1[QSGMB_CFG] are both 0b01. mscc_miim_read: phyad 8 reg 0x1 MIIM_DATA 0x2d mscc_miim_read: phyad 8 reg 0x5 MIIM_DATA 0x5801 mscc_miim_read: phyad 8 reg 0x1 MIIM_DATA 0x2d mscc_miim_read: phyad 8 reg 0x5 MIIM_DATA 0x5801 mscc_miim_read: phyad 9 reg 0x1 MIIM_DATA 0x2d mscc_miim_read: phyad 9 reg 0x5 MIIM_DATA 0x5801 mscc_miim_read: phyad 9 reg 0x1 MIIM_DATA 0x2d mscc_miim_read: phyad 9 reg 0x5 MIIM_DATA 0x5801 mscc_miim_read: phyad 10 reg 0x1 MIIM_DATA 0x2d mscc_miim_read: phyad 10 reg 0x5 MIIM_DATA 0x5801 mscc_miim_read: phyad 10 reg 0x1 MIIM_DATA 0x2d mscc_miim_read: phyad 10 reg 0x5 MIIM_DATA 0x5801 mscc_miim_read: phyad 11 reg 0x1 MIIM_DATA 0x2d mscc_miim_read: phyad 11 reg 0x5 MIIM_DATA 0x5801 mscc_miim_read: phyad 11 reg 0x1 MIIM_DATA 0x2d mscc_miim_read: phyad 11 reg 0x5 MIIM_DATA 0x5801 mscc_miim_read: phyad 4 reg 0x1 MIIM_DATA 0x3002d, ERROR mscc_miim_read: phyad 4 reg 0x5 MIIM_DATA 0x3da01, ERROR mscc_miim_read: phyad 5 reg 0x1 MIIM_DATA 0x3002d, ERROR mscc_miim_read: phyad 5 reg 0x5 MIIM_DATA 0x35801, ERROR mscc_miim_read: phyad 5 reg 0x1 MIIM_DATA 0x3002d, ERROR mscc_miim_read: phyad 5 reg 0x5 MIIM_DATA 0x35801, ERROR mscc_miim_read: phyad 6 reg 0x1 MIIM_DATA 0x3002d, ERROR mscc_miim_read: phyad 6 reg 0x5 MIIM_DATA 0x35801, ERROR mscc_miim_read: phyad 6 reg 0x1 MIIM_DATA 0x3002d, ERROR mscc_miim_read: phyad 6 reg 0x5 MIIM_DATA 0x35801, ERROR mscc_miim_read: phyad 7 reg 0x1 MIIM_DATA 0x3002d, ERROR mscc_miim_read: phyad 7 reg 0x5 MIIM_DATA 0x35801, ERROR mscc_miim_read: phyad 7 reg 0x1 MIIM_DATA 0x3002d, ERROR mscc_miim_read: phyad 7 reg 0x5 MIIM_DATA 0x35801, ERROR As can be seen, the data in MIIM_DATA is still valid despite having the MSCC_MIIM_DATA_ERROR bits set. The driver as introduced in commit 84705fc1 ("net: dsa: felix: introduce support for Seville VSC9953 switch") was ignoring these bits, perhaps deliberately (although unbeknownst to me). This is an old IP and the hardware team cannot seem to be able to help me track down a plausible reason for these failures. I'll keep investigating, but in the meantime, this is a direct regression which must be restored to a working state. The only thing I can do is keep ignoring the errors as before.

Even after commit 908d4bb7 ("qede: fix interrupt coalescing configuration"), some entries of the coal_entry array may theoretically be used uninitialized: 1. qede_alloc_fp_array() allocates QEDE_MAX_RSS_CNT entries for coal_entry. The initial allocation uses kcalloc, so everything is initialized. 2. The user sets a small number of queues (ethtool -L). coal_entry is reallocated for the actual small number of queues. 3. The user sets a bigger number of queues. coal_entry is reallocated bigger. The added entries are not necessarily initialized. In practice, the reallocations will actually keep using the originally allocated region of memory, but we should not rely on it. The reallocation is unnecessary. coal_entry can always have QEDE_MAX_RSS_CNT entries. Fixes: 908d4bb7 ("qede: fix interrupt coalescing configuration") Signed-off-by:

The callback context for sending/receiving APDUs to/from the selected secure element is allocated inside nfc_genl_se_io and supposed to be eventually freed in se_io_cb callback function. However, there are several error paths where the bwi_timer is not charged to call se_io_cb later, and the cb_context is leaked. The patch proposes to free the cb_context explicitly on those error paths. At the moment we can't simply check 'dev->ops->se_io()' return value as it may be negative in both cases: when the timer was charged and was not.

CONFIG_ICE_GNSS was added by commit c7ef8221 ("ice: use GNSS subsystem instead of TTY") as a way to allow the ice driver to optionally support GNSS features without forcing a dependency on CONFIG_GNSS. The original implementation of that commit at [1] used IS_REACHABLE. This was rejected by Olek at [2] with the suggested implementation of CONFIG_ICE_GNSS. Eventually after merging, Linus reported a .config which had CONFIG_ICE_GNSS = y when both GNSS = n and ICE = n. This confused him and he felt that the config option was not useful, and commented about it at [3]. CONFIG_ICE_GNSS is defined to y whenever GNSS = ICE. This results in it being set in cases where both options are not enabled. The goal of CONFIG_ICE_GNSS is to ensure that the GNSS support in the ice driver is enabled when GNSS is enabled. The complaint from Olek about the original IS_REACHABLE was due to the required IS_REACHABLE checks throughout the ice driver code and the fact that ice_gnss.c was compiled regardless of GNSS support. This can be fixed in the Makefile by using ice-$(CONFIG_GNSS) += ice_gnss.o In this case, if GNSS = m and ICE = y, we can result in some confusing behavior where GNSS support is not enabled because its not built in. See [4]. To disallow this, have CONFIG_ICE depend on GNSS || GNSS = n. This ensures that we cannot enable CONFIG_ICE as builtin while GNSS is a module. Drop CONFIG_ICE_GNSS, and replace the IS_ENABLED checks for it with checks for GNSS. Update the Makefile to add the ice_gnss.o object based on CONFIG_GNSS. This works to ensure that GNSS support can optionally be enabled, doesn't have an unnnecessary extra config option, and has Kbuild enforce the dependency such that you can't accidentally enable GNSS as a module and ICE as a builtin.

When CONFIG_NET_CLS_ACT is disabled: ../net/sched/cls_api.c:141:13: warning: 'tcf_exts_miss_cookie_base_destroy' defined but not used [-Wunused-function] 141 | static void tcf_exts_miss_cookie_base_destroy(struct tcf_exts *exts) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Due to the way the code is structured, it is possible for a definition of tcf_exts_miss_cookie_base_destroy() to be present without actually being used. Its single callsite is in an '#ifdef CONFIG_NET_CLS_ACT' block but a definition will always be present in the file. The version of tcf_exts_miss_cookie_base_destroy() that actually does something depends on CONFIG_NET_TC_SKB_EXT, so the stub function is used in both CONFIG_NET_CLS_ACT=n and CONFIG_NET_CLS_ACT=y + CONFIG_NET_TC_SKB_EXT=n configurations. Move the call to tcf_exts_miss_cookie_base_destroy() in tcf_exts_destroy() out of the '#ifdef CONFIG_NET_CLS_ACT', so that it always appears used to the compiler, while not changing any behavior with any of the various configuration combinations.

The search for max attr in a struct records attrs with value larger than 0 only (max_val is set to 0 at the start). Adjust the comparison, alternatively max_val could be init'ed to -1. Somehow picking the last attr of a value seems like a good idea in general. Reported-by:

On success, mlx5_geneve_tlv_option_create returns non negative Geneve object id. In case the object id is positive value the caller functions will handle it as an error (non zero) and will fail to offload the Geneve rule. Fix this by changing caller function ,mlx5_geneve_tlv_option_add, to return 0 in case valid non negative object id was provided.

Currently, during the early stages of their unloading, particularly during SRIOV disablement, PFs/ECPFs wait on the release of all of their VFs memory pages. Furthermore, ECPFs are considered the page supplier for host VFs, hence the host VFs memory pages are freed only during ECPF cleanup when host interfaces get disabled. Thus, disabling SRIOV early in unload timeline causes the DPU ECPF to stall on driver unload while waiting on the release of host VF pages that won't be freed before host interfaces get disabled later on. Therefore, for ECPFs, wait on the release of VFs pages only after the disablement of host PFs during ECPF cleanup flow. Then, host PFs and VFs are disabled and their memory shall be freed accordingly. Fixes: 143a41d7 ("net/mlx5: Disable SRIOV before PF removal") Signed-off-by:

Fifo indexes are not checked during pop operations and it leads to potential use-after-free when poping from empty queue. Such case was possible during re-sync action. WARN_ON_ONCE covers future cases. There were out-of-order cqe spotted which lead to drain of the queue and use-after-free because of lack of fifo pointers check. Special check and counter are added to avoid resync operation if SKB could not exist in the fifo because of OOO cqe (skb_id must be between consumer and producer index).

During ptp resync operation SKBs were poped from the fifo but were never freed neither by napi_consume nor by dev_kfree_skb_any. Add call to napi_consume_skb to properly free SKBs. Another leak was happening because mlx5e_skb_fifo_has_room() had an error in the check. Comparing free running counters works well unless C promotes the types to something wider than the counter. In this case counters are u16 but the result of the substraction is promouted to int and it causes wrong result (negative value) of the check when producer have already overlapped but consumer haven't yet. Explicit cast to u16 fixes the issue. Fixes: 58a51894 ("net/mlx5e: Add resiliency for PTP TX port timestamp") Reviewed-by:

dev_kfree_skb() is aliased to consume_skb(). When a driver is dropping a packet by calling dev_kfree_skb_any() we should propagate the drop reason instead of pretending the packet was consumed.

With this refcnt added in sctp_stream_priorities, we don't need to traverse all streams to check if the prio is used by other streams when freeing one stream's prio in sctp_sched_prio_free_sid(). This can avoid a nested loop (up to 65535 * 65535), which may cause a stuck as Ying reported: watchdog: BUG: soft lockup - CPU#23 stuck for 26s!

When checksum offload is disabled in the driver via ethtool, the PTP 1-step sync packets contain incorrect checksum, since the stack calculates the checksum before driver updates PTP timestamp field in the packet. This results in PTP packets getting dropped at the other end. This patch fixes the issue by re-calculating the UDP checksum after updating PTP timestamp field in the driver.

This behavior may introduce new regressions on systems where EEE was disabled by default (BIOS or boot loader configuration or by other ways.) At same time, with this patches, we would overwrite EEE advertisement configuration made over ethtool. To avoid this issues, we need to cache initial and ethtool advertisement configuration and store it for later use.
