Implement the release path to symmetrically destroy the mutex. Also switch a different lock from spinlock to mutex as the code path has the potential to sleep and doesn't need the spinlock context otherwise (Brett Creeley) - Fix an issue detected via randconfig where KVM tries to symbol_get an undeclared function. The symbol is temporarily declared unconditionally here, which resolves the problem and avoids churn relative to a series pending for the next merge window which resolves some of this symbol ugliness, but also fixes Kconfig dependencies (Sean Christopherson) * tag 'vfio-v6.7-rc4' of https://github.com/awilliam/linux-vfio: vfio: Drop vfio_file_iommu_group() stub to fudge around a KVM wart vfio/pds: Fix possible sleep while in atomic context vfio/pds: Fix mutex lock->magic != lock warning 02 December 2023, 23:37:39 UTC

The objpool uses a copy of object slot index internal loop, but the slot index can be changed on another processor in parallel. In that case, the difference of 'head' local copy and the 'slot->last' index will be bigger than local slot size. In that case, we need to re-read the slot::head to update it. - kretprobe: Fix to use appropriate rcu API for kretprobe holder. Since kretprobe_holder::rp is RCU managed, it should use rcu_assign_pointer() and rcu_dereference_check() correctly. Also adding __rcu tag for finding wrong usage by sparse. - rethook: Fix to use appropriate rcu API for rethook::handler. The same as kretprobe, rethook::handler is RCU managed and it should use rcu_assign_pointer() and rcu_dereference_check(). This also adds __rcu tag for finding wrong usage by sparse. * tag 'probes-fixes-v6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: rethook: Use __rcu pointer for rethook::handler kprobes: consistent rcu api usage for kretprobe holder lib: objpool: fix head overrun on RK3588 SBC 02 December 2023, 23:02:49 UTC

0e4237a Ming Lei 01 December 2023, 08:56:05 UTC blk-mq: don't count completed flush data request as inflight in case of quiesce Request queue quiesce may interrupt flush sequence, and the original request may have been marked as COMPLETE, but can't get finished because of queue quiesce. This way is fine from driver viewpoint, because flush sequence is block layer concept, and it isn't related with driver. However, driver(such as dm-rq) can call blk_mq_queue_inflight() to count & drain inflight requests, then the wait & drain never gets done because the completed & not-finished flush request is counted as inflight. Fix this issue by not counting completed flush data request as inflight in case of quiesce.

a1461f1 Masami Hiramatsu (Google) 01 December 2023, 05:53:56 UTC rethook: Use __rcu pointer for rethook::handler Since the rethook::handler is an RCU-maganged pointer so that it will notice readers the rethook is stopped (unregistered) or not, it should be an __rcu pointer and use appropriate functions to be accessed. This will use appropriate memory barrier when accessing it. OTOH, rethook::data is never changed, so we don't need to check it in get_kretprobe(). NOTE: To avoid sparse warning, rethook::handler is defined by a raw function pointer type with __rcu instead of rethook_handler_t.

d839a65 JP Kobryn 01 December 2023, 05:53:55 UTC kprobes: consistent rcu api usage for kretprobe holder It seems that the pointer-to-kretprobe "rp" within the kretprobe_holder is RCU-managed, based on the (non-rethook) implementation of get_kretprobe(). The thought behind this patch is to make use of the RCU API where possible when accessing this pointer so that the needed barriers are always in place and to self-document the code. The __rcu annotation to "rp" allows for sparse RCU checking. Plain writes done to the "rp" pointer are changed to make use of the RCU macro for assignment. For the single read, the implementation of get_kretprobe() is simplified by making use of an RCU macro which accomplishes the same, but note that the log warning text will be more generic. I did find that there is a difference in assembly generated between the usage of the RCU macros vs without. For example, on arm64, when using rcu_assign_pointer(), the corresponding store instruction is a store-release (STLR) which has an implicit barrier. When normal assignment is done, a regular store (STR) is found. In the macro case, this seems to be a result of rcu_assign_pointer() using smp_store_release() when the value to write is not NULL.

d67f39d wuqiang.matt 01 December 2023, 05:53:55 UTC lib: objpool: fix head overrun on RK3588 SBC objpool overrun stress with test_objpool on OrangePi5+ SBC triggered the following kernel warnings: WARNING: CPU: 6 PID: 3115 at lib/objpool.c:168 objpool_push+0xc0/0x100 This message is from objpool.c:168: WARN_ON_ONCE(tail - head > pool->nr_objs); The overrun test case is to validate the case that pre-allocated objects are insufficient: 8 objects are pre-allocated for each node and consumer thread per node tries to grab 16 objects in a row. The testing system is OrangePI 5+, with RK3588, a big.LITTLE SOC with 4x A76 and 4x A55. When disabling either all 4 big or 4 little cores, the overrun tests run well, and once with big and little cores mixed together, the overrun test would always cause an overrun loop. It's likely the memory timing differences of big and little cores cause this trouble. Here are the debugging data of objpool_try_get_slot after try_cmpxchg_release: objpool_pop: cpu: 4/0 0:0 head: 278/279 tail:278 last:276/278 The local copies of 'head' and 'last' were 278 and 276, and reloading of 'slot->head' and 'slot->last' got 279 and 278. After try_cmpxchg_release 'slot->head' became 'head + 1', which is correct. But what's wrong here is the stale value of 'last', and that stale value of 'last' finally led the overrun of 'head'. Memory updating of 'last' and 'head' are performed in push() and pop() independently, which could be the culprit leading this out of order visibility of 'last' and 'head'. So for objpool_try_get_slot(), it's not enough only checking the condition of 'head != slot', the implicit condition 'last - head <= nr_objs' must also be explicitly asserted to guarantee 'last' is always behind 'head' before the object retrieving. This patch will check and try reloading of 'head' and 'last' to ensure 'last' is behind 'head' at the time of object retrieving. Performance testings show the average impact is about 0.1% for X86_64 and 1.12% for ARM64.

4ea95c0 Sean Christopherson 30 November 2023, 00:10:00 UTC vfio: Drop vfio_file_iommu_group() stub to fudge around a KVM wart Drop the vfio_file_iommu_group() stub and instead unconditionally declare the function to fudge around a KVM wart where KVM tries to do symbol_get() on vfio_file_iommu_group() (and other VFIO symbols) even if CONFIG_VFIO=n. Ensuring the symbol is always declared fixes a PPC build error when modules are also disabled, in which case symbol_get() simply points at the address of the symbol (with some attributes shenanigans). Because KVM does symbol_get() instead of directly depending on VFIO, the lack of a fully defined symbol is not problematic (ugly, but "fine"). arch/powerpc/kvm/../../../virt/kvm/vfio.c:89:7: error: attribute declaration must precede definition [-Werror,-Wignored-attributes] fn = symbol_get(vfio_file_iommu_group); ^ include/linux/module.h:805:60: note: expanded from macro 'symbol_get' #define symbol_get(x) ({ extern typeof(x) x __attribute__((weak,visibility("hidden"))); &(x); }) ^ include/linux/vfio.h:294:35: note: previous definition is here static inline struct iommu_group *vfio_file_iommu_group(struct file *file) ^ arch/powerpc/kvm/../../../virt/kvm/vfio.c:89:7: error: attribute declaration must precede definition [-Werror,-Wignored-attributes] fn = symbol_get(vfio_file_iommu_group); ^ include/linux/module.h:805:65: note: expanded from macro 'symbol_get' #define symbol_get(x) ({ extern typeof(x) x __attribute__((weak,visibility("hidden"))); &(x); }) ^ include/linux/vfio.h:294:35: note: previous definition is here static inline struct iommu_group *vfio_file_iommu_group(struct file *file) ^ 2 errors generated. Although KVM is firmly in the wrong (there is zero reason for KVM to build virt/kvm/vfio.c when VFIO is disabled), fudge around the error in VFIO as the stub is unnecessary and doesn't serve its intended purpose (KVM is the only external user of vfio_file_iommu_group()), and there is an in-flight series to clean up the entire KVM<->VFIO interaction, i.e. fixing this in KVM would result in more churn in the long run, and the stub needs to go away regardless.

edf9bc3 Claudiu Beznea 28 November 2023, 08:04:39 UTC net: ravb: Keep reverse order of operations in ravb_remove() On RZ/G3S SMARC Carrier II board having RGMII connections b/w Ethernet MACs and PHYs it has been discovered that doing unbind/bind for ravb driver in a loop leads to wrong speed and duplex for Ethernet links and broken connectivity (the connectivity cannot be restored even with bringing interface down/up). Before doing unbind/bind the Ethernet interfaces were configured though systemd. The sh instructions used to do unbind/bind were: $ cd /sys/bus/platform/drivers/ravb/ $ while :; do echo 11c30000.ethernet > unbind ; \ echo 11c30000.ethernet > bind; done It has been discovered that there is a race b/w IOCTLs initialized by systemd at the response of success binding and the "ravb_write(ndev, CCC_OPC_RESET, CCC)" call in ravb_remove() as follows: 1/ as a result of bind success the user space open/configures the interfaces tough an IOCTL; the following stack trace has been identified on RZ/G3S: Call trace: dump_backtrace+0x9c/0x100 show_stack+0x20/0x38 dump_stack_lvl+0x48/0x60 dump_stack+0x18/0x28 ravb_open+0x70/0xa58 __dev_open+0xf4/0x1e8 __dev_change_flags+0x198/0x218 dev_change_flags+0x2c/0x80 devinet_ioctl+0x640/0x708 inet_ioctl+0x1e4/0x200 sock_do_ioctl+0x50/0x108 sock_ioctl+0x240/0x358 __arm64_sys_ioctl+0xb0/0x100 invoke_syscall+0x50/0x128 el0_svc_common.constprop.0+0xc8/0xf0 do_el0_svc+0x24/0x38 el0_svc+0x34/0xb8 el0t_64_sync_handler+0xc0/0xc8 el0t_64_sync+0x190/0x198 2/ this call may execute concurrently with ravb_remove() as the unbind/bind operation was executed in a loop 3/ if the operation mode is changed to RESET (through ravb_write(ndev, CCC_OPC_RESET, CCC) call in ravb_remove()) while the above ravb_open() is in progress it may lead to MAC (or PHY, or MAC-PHY connection, the right point hasn't been identified at the moment) to be broken, thus the Ethernet connectivity fails to restore. The simple fix for this is to move ravb_write(ndev, CCC_OPC_RESET, CCC)) after unregister_netdev() to avoid resetting the controller while the netdev interface is still registered. To avoid future issues in ravb_remove(), the patch follows the proper order of operations in ravb_remove(): reverse order compared with ravb_probe(). This avoids described races as the IOCTLs as well as unregister_netdev() (called now at the beginning of ravb_remove()) calls rtnl_lock() before continuing and IOCTLs check (though devinet_ioctl()) if device is still registered just after taking the lock: int devinet_ioctl(struct net *net, unsigned int cmd, struct ifreq *ifr) { // ... rtnl_lock(); ret = -ENODEV; dev = __dev_get_by_name(net, ifr->ifr_name); if (!dev) goto done; // ... done: rtnl_unlock(); out: return ret; } Fixes: c156633f1353 ("Renesas Ethernet AVB driver proper") Reviewed-by: Sergey Shtylyov <s.shtylyov@omp.ru> Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com> 30 November 2023, 09:59:07 UTC

9f74a3d Dave Ertman 27 November 2023, 21:23:38 UTC ice: Fix VF Reset paths when interface in a failed over aggregate There is an error when an interface has the following conditions: - PF is in an aggregate (bond) - PF has VFs created on it - bond is in a state where it is failed-over to the secondary interface - A VF reset is issued on one or more of those VFs The issue is generated by the originating PF trying to rebuild or reconfigure the VF resources. Since the bond is failed over to the secondary interface the queue contexts are in a modified state. To fix this issue, have the originating interface reclaim its resources prior to the tear-down and rebuild or reconfigure. Then after the process is complete, move the resources back to the currently active interface. There are multiple paths that can be used depending on what triggered the event, so create a helper function to move the queues and use paired calls to the helper (back to origin, process, then move back to active interface) under the same lag_mutex lock.

8866730 John Fastabend 29 November 2023, 01:25:56 UTC bpf, sockmap: af_unix stream sockets need to hold ref for pair sock AF_UNIX stream sockets are a paired socket. So sending on one of the pairs will lookup the paired socket as part of the send operation. It is possible however to put just one of the pairs in a BPF map. This currently increments the refcnt on the sock in the sockmap to ensure it is not free'd by the stack before sockmap cleans up its state and stops any skbs being sent/recv'd to that socket. But we missed a case. If the peer socket is closed it will be free'd by the stack. However, the paired socket can still be referenced from BPF sockmap side because we hold a reference there. Then if we are sending traffic through BPF sockmap to that socket it will try to dereference the free'd pair in its send logic creating a use after free. And following splat: [59.900375] BUG: KASAN: slab-use-after-free in sk_wake_async+0x31/0x1b0 [59.901211] Read of size 8 at addr ffff88811acbf060 by task kworker/1:2/954 [...] [59.905468] Call Trace: [59.905787] <TASK> [59.906066] dump_stack_lvl+0x130/0x1d0 [59.908877] print_report+0x16f/0x740 [59.910629] kasan_report+0x118/0x160 [59.912576] sk_wake_async+0x31/0x1b0 [59.913554] sock_def_readable+0x156/0x2a0 [59.914060] unix_stream_sendmsg+0x3f9/0x12a0 [59.916398] sock_sendmsg+0x20e/0x250 [59.916854] skb_send_sock+0x236/0xac0 [59.920527] sk_psock_backlog+0x287/0xaa0 To fix let BPF sockmap hold a refcnt on both the socket in the sockmap and its paired socket. It wasn't obvious how to contain the fix to bpf_unix logic. The primarily problem with keeping this logic in bpf_unix was: In the sock close() we could handle the deref by having a close handler. But, when we are destroying the psock through a map delete operation we wouldn't have gotten any signal thorugh the proto struct other than it being replaced. If we do the deref from the proto replace its too early because we need to deref the sk_pair after the backlog worker has been stopped. Given all this it seems best to just cache it at the end of the psock and eat 8B for the af_unix and vsock users. Notice dgram sockets are OK because they handle locking already.
