2019-09-20perf stat: Fix a segmentation fault when using repeat foreverSrikar Dronamraju
Observe a segmentation fault when 'perf stat' is asked to repeat forever with the interval option. Without fix: # perf stat -r 0 -I 5000 -e cycles -a sleep 10 # time counts unit events 5.000211692 3,13,89,82,34,157 cycles 10.000380119 1,53,98,52,22,294 cycles 10.040467280 17,16,79,265 cycles Segmentation fault This problem was only observed when we use forever option aka -r 0 and works with limited repeats. Calling print_counter with ts being set to NULL, is not a correct option when interval is set. Hence avoid print_counter(NULL,..) if interval is set.

2019-09-20perf stat: Reset previous counts on repeat with intervalSrikar Dronamraju
When using 'perf stat' with repeat and interval option, it shows wrong values for events. The wrong values will be shown for the first interval on the second and subsequent repetitions. Without the fix: # perf stat -r 3 -I 2000 -e faults -e sched:sched_switch -a sleep 5 2.000282489 53 faults 2.000282489 513 sched:sched_switch 4.005478208 3,721 faults 4.005478208 2,666 sched:sched_switch 5.025470933 395 faults 5.025470933 1,307 sched:sched_switch 2.009602825 1,84,46,74,40,73,70,95,47,520 faults <------ 2.009602825 1,84,46,74,40,73,70,95,49,568 sched:sched_switch <------ 4.019612206 4,730 faults 4.019612206 2,746 sched:sched_switch 5.039615484 3,953 faults 5.039615484 1,496 sched:sched_switch 2.000274620 1,84,46,74,40,73,70,95,47,520 faults <------ 2.000274620 1,84,46,74,40,73,70,95,47,520 sched:sched_switch <------ 4.000480342 4,282 faults 4.000480342 2,303 sched:sched_switch 5.000916811 1,322 faults 5.000916811 1,064 sched:sched_switch # prev_raw_counts is allocated when using intervals. This is used when calculating the difference in the counts of events when using interval. The current counts are stored in prev_raw_counts to calculate the differences in the next iteration. On the first interval of the second and subsequent repetitions, prev_raw_counts would be the values stored in the last interval of the previous repetitions, while the current counts will only be for the first interval of the current repetition. Hence there is a possibility of events showing up as big number. Fix this by resetting prev_raw_counts whenever perf stat repeats the command.

2019-09-20hwrng: core - don't wait on add_early_randomness()Laurent Vivier
add_early_randomness() is called by hwrng_register() when the hardware is added. If this hardware and its module are present at boot, and if there is no data available the boot hangs until data are available and can't be interrupted. For instance, in the case of virtio-rng, in some cases the host can be not able to provide enough entropy for all the guests. We can have two easy ways to reproduce the problem but they rely on misconfiguration of the hypervisor or the egd daemon: - if virtio-rng device is configured to connect to the egd daemon of the host but when the virtio-rng driver asks for data the daemon is not connected, - if virtio-rng device is configured to connect to the egd daemon of the host but the egd daemon doesn't provide data. The guest kernel will hang at boot until the virtio-rng driver provides enough data. To avoid that, call rng_get_data() in non-blocking mode (wait=0) from add_early_randomness().

2019-09-20crypto: hisilicon - Fix double free in sec_free_hw_sgl()Yunfeng Ye
There are two problems in sec_free_hw_sgl(): First, when sgl_current->next is valid, @hw_sgl will be freed in the first loop, but it free again after the loop. Second, sgl_current and sgl_current->next_sgl is not match when dma_pool_free() is invoked, the third parameter should be the dma address of sgl_current, but sgl_current->next_sgl is the dma address of next chain, so use sgl_current->next_sgl is wrong. Fix this by deleting the last dma_pool_free() in sec_free_hw_sgl(), modifying the condition for while loop, and matching the address for dma_pool_free().

Pruning a bit more the includes dependency tree. Building this thing on lots of containers takes time, we better reduce the time per build, each container is doing 6 builds when clang and clang-devel are available, and the plan is to do a 'make -C tools/perf build-test' that have many more. Also helps when doing normal development, as touching some random file will have a much reduced chance of triggering lots of rebuilds.

2019-09-20netfilter: nf_tables: allow lookups in dynamic setsFlorian Westphal
This un-breaks lookups in sets that have the 'dynamic' flag set. Given this active example configuration: table filter { set set1 { type ipv4_addr size 64 flags dynamic,timeout timeout 1m } chain input { type filter hook input priority 0; policy accept; } } ... this works: nft add rule ip filter input add @set1 { ip saddr } -> whenever rule is triggered, the source ip address is inserted into the set (if it did not exist). This won't work: nft add rule ip filter input ip saddr @set1 counter Error: Could not process rule: Operation not supported In other words, we can add entries to the set, but then can't make matching decision based on that set. That is just wrong -- all set backends support lookups (else they would not be very useful). The failure comes from an explicit rejection in nft_lookup.c. Looking at the history, it seems like NFT_SET_EVAL used to mean 'set contains expressions' (aka. "is a meter"), for instance something like nft add rule ip filter input meter example { ip saddr limit rate 10/second } or nft add rule ip filter input meter example { ip saddr counter } The actual meaning of NFT_SET_EVAL however, is 'set can be updated from the packet path'. 'meters' and packet-path insertions into sets, such as 'add @set { ip saddr }' use exactly the same kernel code (nft_dynset.c) and thus require a set backend that provides the ->update() function. The only set that provides this also is the only one that has the NFT_SET_EVAL feature flag. Removing the wrong check makes the above example work. While at it, also fix the flag check during set instantiation to allow supported combinations only.

2019-09-20ALSA: hda/realtek - PCI quirk for Medion E4254Jan-Marek Glogowski
The laptop has a combined jack to attach headsets on the right. The BIOS encodes them as two different colored jacks at the front, but otherwise it seems to be configured ok. But any adaption of the pins config on its own doesn't fix the jack detection to work in Linux. Still Windows works correct. This is somehow fixed by chaining ALC256_FIXUP_ASUS_HEADSET_MODE, which seems to register the microphone jack as a headset part and also results in fixing jack sensing, visible in dmesg as: -snd_hda_codec_realtek hdaudioC0D0: Mic=0x19 +snd_hda_codec_realtek hdaudioC0D0: Headset Mic=0x19 [ Actually the essential change is the location of the jack; the driver created "Front Mic Jack" without the matching volume / mute control element due to its jack location, which confused PA. -- tiwai ] Signed-off-by: Jan-Marek Glogowski <glogow@fbihome.de> Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/8f4f9b20-0aeb-f8f1-c02f-fd53c09679f1@fbihome.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

2019-09-19iomap: split size and error for iomap_dio_rw ->end_ioMatthew Bobrowski
Modify the calling convention for the iomap_dio_rw ->end_io() callback. Rather than passing either dio->error or dio->size as the 'size' argument, instead pass both the dio->error and the dio->size value separately. In the instance that an error occurred during a write, we currently cannot determine whether any blocks have been allocated beyond the current EOF and data has subsequently been written to these blocks within the ->end_io() callback. As a result, we cannot judge whether we should take the truncate failed write path. Having both dio->error and dio->size will allow us to perform such checks within this callback.
