The token table passed into match_token() must be null-terminated, which it currently is not in the perf's address filter string parser, as caught by Vince's perf_fuzzer and KASAN. It doesn't blow up otherwise because of the alignment padding of the table to the next element in the .rodata, which is luck. Fixing by adding a null-terminator to the token table.

Vince Weaver reported the following bug when KASAN is enabled: [ 205.748005] BUG: KASAN: slab-out-of-bounds in snb_uncore_imc_event_del+0x6c/0xa0 at addr ffff8800caa43768 [ 205.758324] Read of size 8 by task perf_fuzzer/6618 It's caused by accessing box->event_list. For client IMC, there are no generic counters. It defines its own fixed free running counters. So event_list and n_events are unused. They can be removed safely, which fixes the bug.

Commit: db4a8356 ("perf/core: Set cgroup in CPU contexts for new cgroup events") failed to verify that event->cgrp is actually the scheduled cgroup in a CPU before setting cpuctx->cgrp. This patch fixes that. Now that there is a different path for scheduled and unscheduled cgroup, add a warning to catch when cpuctx->cgrp is still set after the last cgroup event has been unsheduled. To verify the bug: # Create 2 cgroups. mkdir /dev/cgroups/devices/g1 mkdir /dev/cgroups/devices/g2 # launch a task, bind it to a cpu and move it to g1 CPU=2 while :; do : ; done & P=$! taskset -pc $CPU $P echo $P > /dev/cgroups/devices/g1/tasks # monitor g2 (it runs no tasks) and observe output perf stat -e cycles -I 1000 -C $CPU -G g2 # time counts unit events 1.000091408 7,579,527 cycles g2 2.000350111 <not counted> cycles g2 3.000589181 <not counted> cycles g2 4.000771428 <not counted> cycles g2 # note first line that displays that a task run in g2, despite # g2 having no tasks.

Since commit b45f64d1 ("mlxsw: spectrum_router: Use FIB notifications instead of switchdev calls") we reflect to the device the entire FIB table and not only FIBs that point to netdevs created by the driver. During module removal, FIBs of the second type are removed following NETDEV_UNREGISTER events sent. The other FIBs are still present in both the driver's cache and the device's table. Fix this by iterating over all the FIB tables in the device and flush them. There's no need to take locks, as we're the only writer.

Commit 52f95bbf ("stmmac: fix adjust link call in case of a switch is attached") added some logic to avoid polling the fixed PHY and therefore invoking the adjust_link callback more than once, since this is a fixed PHY and link events won't be generated. This works fine the first time, because we start with phydev->irq = PHY_POLL, so we call adjust_link, then we set phydev->irq = PHY_IGNORE_INTERRUPT and we stop polling the PHY. Now, if we called ndo_close(), which calls both phy_stop() and does an explicit netif_carrier_off(), we end up with a link down. Upon calling ndo_open() again, despite starting the PHY state machine, we have PHY_IGNORE_INTERRUPT set, and we generate no link event at all, so the link is permanently down.

Now when users shutdown a sock with SEND_SHUTDOWN in sctp, even if this sock has no connection (assoc), sk state would be changed to SCTP_SS_CLOSING, which is not as we expect. Besides, after that if users try to listen on this sock, kernel could even panic when it dereference sctp_sk(sk)->bind_hash in sctp_inet_listen, as bind_hash is null when sock has no assoc. This patch is to move sk state change after checking sk assocs is not empty, and also merge these two if() conditions and reduce indent level.

Baoquan He says: ==================== bnx2: Wait for in-flight DMA to complete at probe stage This is v2 post. In commit 3e1be7ad ("bnx2: Reset device during driver initialization"), firmware requesting code was moved from open stage to probe stage. The reason is in kdump kernel hardware iommu need device be reset in driver probe stage, otherwise those in-flight DMA from 1st kernel will continue going and look up into the newly created io-page tables. However bnx2 chip resetting involves firmware requesting issue, that need be done in open stage. Michale Chan suggested we can just wait for the old in-flight DMA to complete at probe stage, then though without device resetting, we don't need to worry the old in-flight DMA could continue looking up the newly created io-page tables. v1->v2: Michael suggested to wait for the in-flight DMA to complete at probe stage. So give up the old method of trying to reset chip at probe stage, take the new way accordingly. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

In commit 022d00ee ("ASoC: lpass-platform: Fix broken pcm data usage") the stream specific information initialization was broken, with the dma channel information not being initialized if there was no alloc_dma_channel() helper function. Before that, the DMA channel number was implicitly initialized to zero because the backing store was allocated with devm_kzalloc(). When the init code was rewritten, that implicit initialization was lost, and gcc rightfully complains about an uninitialized variable being used.

This is a static checker warning, not something I'm desperately concerned about. But snprintf() returns the number of bytes that would have been copied if there were space. We really care about the number of bytes that actually were copied so we should use scnprintf() instead. It probably won't overrun, and in that case we may as well just use sprintf() but these sorts of things make static checkers and code reviewers happier.

efx_copy_channel() doesn't correctly clear the napi_hash related state. This means that when napi_hash_add is called for that channel nothing is done, and we are left with a copy of the napi_hash_node from the old channel. When we later call napi_hash_del() on this channel we have a stale napi_hash_node. Corruption is only seen when there are multiple entries in one of the napi_hash lists. This is made more likely by having a very large number of channels. Testing was carried out with 512 channels - 32 channels on each of 16 ports. This failure typically appears as protection faults within napi_by_id() or napi_hash_add(). efx_copy_channel() is only used when tx or rx ring sizes are changed (ethtool -G).
