The driver exposes interfaces that directly relate to HW state. Upon fatal error, consumers of these interfaces (ULPs) that rely on completion of all their posted work-request could hang, thereby introducing dependencies in shutdown order. To prevent this from happening, we manage the relevant resources (CQs, QPs) that are used by the device. Upon a fatal error, we now generate simulated completions for outstanding WQEs that were not completed at the time the HW was reset. It includes invoking the completion event handler for all involved CQs so that the ULPs will poll those CQs. When polled we return simulated CQEs with IB_WC_WR_FLUSH_ERR return code enabling ULPs to clean up their resources and not wait forever for completions upon receiving remove_one. The above change requires an extra check in the data path to make sure that when device is in error state, the simulated CQEs will be returned and no further WQEs will be posted.

Receive Flow Steering is a nice solution but suffers from hash collisions when a mix of connected and unconnected traffic is received on the host, when flow hash table is populated. Also, clearing flow in inet_release() makes RFS not very good for short lived flows, as many packets can follow close(). (FIN , ACK packets, ...) This patch extends the information stored into global hash table to not only include cpu number, but upper part of the hash value. I use a 32bit value, and dynamically split it in two parts. For host with less than 64 possible cpus, this gives 6 bits for the cpu number, and 26 (32-6) bits for the upper part of the hash. Since hash bucket selection use low order bits of the hash, we have a full hash match, if /proc/sys/net/core/rps_sock_flow_entries is big enough. If the hash found in flow table does not match, we fallback to RPS (if it is enabled for the rxqueue). This means that a packet for an non connected flow can avoid the IPI through a unrelated/victim CPU. This also means we no longer have to clear the table at socket close time, and this helps short lived flows performance.

A typical qdisc setup is the following : bond0 : bonding device, using HTB hierarchy eth1/eth2 : slaves, multiqueue NIC, using MQ + FQ qdisc XPS allows to spread packets on specific tx queues, based on the cpu doing the send. Problem is that dequeues from bond0 qdisc can happen on random cpus, due to the fact that qdisc_run() can dequeue a batch of packets. CPUA -> queue packet P1 on bond0 qdisc, P1->ooo_okay=1 CPUA -> queue packet P2 on bond0 qdisc, P2->ooo_okay=0 CPUB -> dequeue packet P1 from bond0 enqueue packet on eth1/eth2 CPUC -> dequeue packet P2 from bond0 enqueue packet on eth1/eth2 using sk cache (ooo_okay is 0) get_xps_queue() then might select wrong queue for P1, since current cpu might be different than CPUA. P2 might be sent on the old queue (stored in sk->sk_tx_queue_mapping), if CPUC runs a bit faster (or CPUB spins a bit on qdisc lock) Effect of this bug is TCP reorders, and more generally not optimal TX queue placement. (A victim bulk flow can be migrated to the wrong TX queue for a while) To fix this, we have to record sender cpu number the first time dev_queue_xmit() is called for one tx skb. We can union napi_id (used on receive path) and sender_cpu, granted we clear sender_cpu in skb_scrub_packet() (credit to Willem for this union idea) Signed-off-by: NEric Dumazet <edumazet@google.com> Cc: Willem de Bruijn <willemb@google.com> Cc: Nandita Dukkipati <nanditad@google.com> Cc: Yuchung Cheng <ycheng@google.com> Signed-off-by: NDavid S.

Commit 8eb23b9f ("sched: Debug nested sleeps") added code to report on nested sleep conditions, which we generally want to avoid because the inner sleeping operation can re-set the thread state to TASK_RUNNING, but that will then cause the outer sleep loop not actually sleep when it calls schedule. However, that's actually valid traditional behavior, with the inner sleep being some fairly rare case (like taking a sleeping lock that normally doesn't actually need to sleep). And the debug code would actually change the state of the task to TASK_RUNNING internally, which makes that kind of traditional and working code not work at all, because now the nested sleep doesn't just sometimes cause the outer one to not block, but will cause it to happen every time. In particular, it will cause the cardbus kernel daemon (pccardd) to basically busy-loop doing scheduling, converting a laptop into a heater, as reported by Bruno Prémont. But there may be other legacy uses of that nested sleep model in other drivers that are also likely to never get converted to the new model. This fixes both cases: - don't set TASK_RUNNING when the nested condition happens (note: even if WARN_ONCE() only _warns_ once, the return value isn't whether the warning happened, but whether the condition for the warning was true. So despite the warning only happening once, the "if (WARN_ON(..))" would trigger for every nested sleep. - in the cases where we knowingly disable the warning by using "sched_annotate_sleep()", don't change the task state (that is used for all core scheduling decisions), instead use '->task_state_change' that is used for the debugging decision itself. (Credit for the second part of the fix goes to Oleg Nesterov: "Can't we avoid this subtle change in behaviour DEBUG_ATOMIC_SLEEP adds?" with the suggested change to use 'task_state_change' as part of the test) Reported-and-bisected-by: NBruno Prémont <bonbons@linux-vserver.org> Tested-by: NRafael J Wysocki <rjw@rjwysocki.net> Acked-by: NOleg Nesterov <oleg@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de>, Cc: Ilya Dryomov <ilya.dryomov@inktank.com>, Cc: Mike Galbraith <umgwanakikbuti@gmail.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Peter Hurley <peter@hurleysoftware.com>, Cc: Davidlohr Bueso <dave@stgolabs.net>, Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

由 Linus Torvalds 提交于
The core VM already knows about VM_FAULT_SIGBUS, but cannot return a "you should SIGSEGV" error, because the SIGSEGV case was generally handled by the caller - usually the architecture fault handler. That results in lots of duplication - all the architecture fault handlers end up doing very similar "look up vma, check permissions, do retries etc" - but it generally works. However, there are cases where the VM actually wants to SIGSEGV, and applications _expect_ SIGSEGV. In particular, when accessing the stack guard page, libsigsegv expects a SIGSEGV. And it usually got one, because the stack growth is handled by that duplicated architecture fault handler. However, when the generic VM layer started propagating the error return from the stack expansion in commit fee7e49d ("mm: propagate error from stack expansion even for guard page"), that now exposed the existing VM_FAULT_SIGBUS result to user space. And user space really expected SIGSEGV, not SIGBUS. To fix that case, we need to add a VM_FAULT_SIGSEGV, and teach all those duplicate architecture fault handlers about it. They all already have the code to handle SIGSEGV, so it's about just tying that new return value to the existing code, but it's all a bit annoying. This is the mindless minimal patch to do this. A more extensive patch would be to try to gather up the mostly shared fault handling logic into one generic helper routine, and long-term we really should do that cleanup. Just from this patch, you can generally see that most architectures just copied (directly or indirectly) the old x86 way of doing things, but in the meantime that original x86 model has been improved to hold the VM semaphore for shorter times etc and to handle VM_FAULT_RETRY and other "newer" things, so it would be a good idea to bring all those improvements to the generic case and teach other architectures about them too.

The fix from 9fc81d87 ("perf: Fix events installation during moving group") was incomplete in that it failed to recognise that creating a group with events for different CPUs is semantically broken -- they cannot be co-scheduled. Furthermore, it leads to real breakage where, when we create an event for CPU Y and then migrate it to form a group on CPU X, the code gets confused where the counter is programmed -- triggered in practice as well by me via the perf fuzzer. Fix this by tightening the rules for creating groups. Only allow grouping of counters that can be co-scheduled in the same context. This means for the same task and/or the same cpu.

Currently ->get_dqblk() and ->set_dqblk() use struct fs_disk_quota which tracks space limits and usage in 512-byte blocks. However VFS quotas track usage in bytes (as some filesystems require that) and we need to somehow pass this information. Upto now it wasn't a problem because we didn't do any unit conversion (thus VFS quota routines happily stuck number of bytes into d_bcount field of struct fd_disk_quota). Only if you tried to use Q_XGETQUOTA or Q_XSETQLIM for VFS quotas (or Q_GETQUOTA / Q_SETQUOTA for XFS quotas), you got bogus results. Hardly anyone tried this but reportedly some Samba users hit the problem in practice. So when we want interfaces compatible we need to fix this. We bite the bullet and define another quota structure used for passing information from/to ->get_dqblk()/->set_dqblk. It's somewhat sad we have to have more conversion routines in fs/quota/quota.c and another copying of quota structure slows down getting of quota information by about 2% but it seems cleaner than overloading e.g. units of d_bcount to bytes.

st21nfca has 1 physical SWP line and can support up to 2 secure elements (UICC & eSE) thanks to an external switch managed with a gpio. The platform integrator needs to specify thanks to 2 initialization properties, uicc-present and ese-present, if it is suppose to have uicc and/or ese. Of course if the platform does not have an external switch, only one kind of secure element can be supported. Those parameters are under platform integrator responsibilities. During initialization, the white_list will be set according to those parameters. The discovery_se function will assume a secure element is physically present according to uicc-present and ese-present values and will add it to the secure element list. On ese activation, the atr is retrieved to calculate a command exchange timeout based on the first atr(TB) value. The se_io will allow to transfer data over SWP. 2 kind of events may appear after a data is sent over: - ST21NFCA_EVT_TRANSMIT_DATA when receiving an apdu answer - ST21NFCA_EVT_WTX_REQUEST when the secure element needs more time than expected to compute a command. If this timeout expired, a first recovery tentative consist to send a simple software reset proprietary command. If this tentative still fail, a second recovery tentative consist to send a hardware reset proprietary command. This function is only relevant for eSE like secure element. This patch also change the way a pipe is referenced. There can be different pipe connected to the same gate with different host destination (ex: CONNECTIVITY). In order to keep host information every pipe are reference with a tuple (gate, host). In order to reduce changes, we are keeping unchanged the way a gate is addressed on the Terminal Host. However, this is working because we consider the apdu reader gate is only present on the eSE slot also the connectivity gate cannot give a reliable value; it will give the latest stored pipe value.
