2023-02-26qede: avoid uninitialized entries in coal_entry arrayMichal Schmidt
Even after commit 908d4bb7c54c ("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.

2023-02-26nfc: fix memory leak of se_io context in nfc_genl_se_ioFedor Pchelkin
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.

2023-02-26ice: remove unnecessary CONFIG_ICE_GNSSJacob Keller
CONFIG_ICE_GNSS was added by commit c7ef8221ca7d ("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.

2023-02-24net/mlx5: ECPF, wait for VF pages only after disabling host PFsMaher Sanalla
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.

2023-02-24mlx5: fix possible ptp queue fifo use-after-freeVadim Fedorenko
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).

2023-02-24mlx5: fix skb leak while fifo resync and pushVadim Fedorenko
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.

2023-02-22ptp: vclock: use mutex to fix "sleep on atomic" bugÍñigo Huguet
vclocks were using spinlocks to protect access to its timecounter and cyclecounter. Access to timecounter/cyclecounter is backed by the same driver callbacks that are used for non-virtual PHCs, but the usage of the spinlock imposes a new limitation that didn't exist previously: now they're called in atomic context so they mustn't sleep. Some drivers like sfc or ice may sleep on these callbacks, causing errors like "BUG: scheduling while atomic: ptp5/25223/0x00000002" Fix it replacing the vclock's spinlock by a mutex. It fix the mentioned bug and it doesn't introduce longer delays. I've tested synchronizing various different combinations of clocks: - vclock->sysclock - sysclock->vclock - vclock->vclock - hardware PHC in different NIC -> vclock - created 4 vclocks and launch 4 parallel phc2sys processes with lockdep enabled In all cases, comparing the delays reported by phc2sys, they are in the same range of values than before applying the patch.

Also add cmpxchg_user_key() to uaccess functions, which will be used by KVM to access KVM guest memory with a specific storage key - Add support for user space events counting to CPUMF - Cleanup the vfio/ccw code, which also allows now to properly support 2K Format-2 IDALs - Move kernel page table allocation and initialization to decompressor, which finally allows to enter the kernel with dynamic address translation enabled. This in turn allows to get rid of code with special handling in the kernel, which has to distinguish if DAT is on or off - Replace kretprobe with rethook - Various improvements to vfio/ap queue resets: - Use TAPQ to verify completion of a reset in progress rather than multiple invocations of ZAPQ. - Check TAPQ response codes when verifying successful completion of ZAPQ. - Fix erroneous handling of some error response codes. - Increase the maximum amount of time to wait for successful completion of ZAPQ - Rework system call wrappers to get rid of alias functions, which were only left on s390 - Cleanup diag288_wdt watchdog driver. It has been agreed on with Guenter Roeck that this goes upstream via the s390 tree - Add missing loadparm parameter handling for list-directed ECKD ipl/reipl - Various improvements to memory detection code - Remove arch_cpu_idle_time() since the current implementation is broken, and allows user space observable accounted idle times which can temporarily decrease - Add Reset DAT-Protection support: (only) allow to change PTEs from RO to RW with a new RDP instruction. Unlike the currently used IPTE instruction, this does not necessarily guarantee that TLBs of all CPUs are synchronously flushed; and that remote CPUs can see spurious protection faults.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull RCU updates from Paul McKenney: - Documentation updates - Miscellaneous fixes, perhaps most notably: - Throttling callback invocation based on the number of callbacks that are now ready to invoke instead of on the total number of callbacks - Several patches that suppress false-positive boot-time diagnostics, for example, due to lockdep not yet being initialized - Make expedited RCU CPU stall warnings dump stacks of any tasks that are blocking the stalled grace period. (Normal RCU CPU stall warnings have done this for many years) - Lazy-callback fixes to avoid delays during boot, suspend, and resume. (Note that lazy callbacks must be explicitly enabled, so this should not (yet) affect production use cases) - Make kfree_rcu() and friends take advantage of polled grace periods, thus reducing memory footprint by almost two orders of magnitude, admittedly on a microbenchmark This also begins the transition from kfree_rcu(p) to kfree_rcu_mightsleep(p). This transition was motivated by bugs where kfree_rcu(p), which can block, was typed instead of the intended kfree_rcu(p, rh) - SRCU updates, perhaps most notably fixing a bug that causes SRCU to fail when booted on a system with a non-zero boot CPU. This surprising situation actually happens for kdump kernels on the powerpc architecture This also adds an srcu_down_read() and srcu_up_read(), which act like srcu_read_lock() and srcu_read_unlock(), but allow an SRCU read-side critical section to be handed off from one task to another - Clean up the now-useless SRCU Kconfig option There are a few more commits that are not yet acked or pulled into maintainer trees, and these will be in a pull request for a later merge window - RCU-tasks updates, perhaps most notably these fixes: - A strange interaction between PID-namespace unshare and the RCU-tasks grace period that results in a low-probability but very real hang - A race between an RCU tasks rude grace period on a single-CPU system and CPU-hotplug addition of the second CPU that can result in a too-short grace period - A race between shrinking RCU tasks down to a single callback list and queuing a new callback to some other CPU, but where that queuing is delayed for more than an RCU grace period. This can result in that callback being stranded on the non-boot CPU - Torture-test updates and fixes - Torture-test scripting updates and fixes - Provide additional RCU CPU stall-warning information in kernels built with CONFIG_RCU_CPU_STALL_CPUTIME=y, and restore the full five-minute timeout limit for expedited RCU CPU stall warnings * tag 'rcu.2023.02.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: (80 commits) rcu/kvfree: Add kvfree_rcu_mightsleep() and kfree_rcu_mightsleep() kernel/notifier: Remove CONFIG_SRCU init: Remove "select SRCU" fs/quota: Remove "select SRCU" fs/notify: Remove "select SRCU" fs/btrfs: Remove "select SRCU" fs: Remove CONFIG_SRCU drivers/pci/controller: Remove "select SRCU" drivers/net: Remove "select SRCU" drivers/md: Remove "select SRCU" drivers/hwtracing/stm: Remove "select SRCU" drivers/dax: Remove "select SRCU" drivers/base: Remove CONFIG_SRCU rcu: Disable laziness if lazy-tracking says so rcu: Track laziness during boot and suspend rcu: Remove redundant call to rcu_boost_kthread_setaffinity() rcu: Allow up to five minutes expedited RCU CPU stall-warning timeouts rcu: Align the output of RCU CPU stall warning messages rcu: Add RCU stall diagnosis information sched: Add helper nr_context_switches_cpu() ...

Sigh! - Initialize the restart block in the nanosleep syscalls to be directed to the no restart function instead of doing a partial setup on entry.

2023-02-20net/mlx5e: TC, Set CT miss to the specific ct action instancePaul Blakey
Currently, CT misses restore the missed chain on the tc skb extension so tc will continue from the relevant chain. Instead, restore the CT action's miss cookie on the extension, which will instruct tc to continue from the this specific CT action instance on the relevant filter's action list. Map the CT action's miss_cookie to a new miss object (ACT_MISS), and use this miss mapping instead of the current chain miss object (CHAIN_MISS) for CT action misses. To restore this new miss mapping value, add a RX restore rule for each such mapping value.
