2019-08-22ceph: fix buffer free while holding i_ceph_lock in fill_inode()Luis Henriques1-3/+4

2019-08-22ALSA: usb-audio: Check mixer unit bitmap yet more strictlyTakashi Iwai1-8/+28
The bmControls (for UAC1) or bmMixerControls (for UAC2/3) bitmap has a variable size depending on both input and output pins. Its size is to fit with input * output bits. The problem is that the input size can't be determined simply from the unit descriptor itself but it needs to parse the whole connected sources. Although the uac_mixer_unit_get_channels() tries to check some possible overflow of this bitmap, it's incomplete due to the lack of the evaluation of input pins. For covering possible overflows, this patch adds the bitmap overflow check in the loop of input pins in parse_audio_mixer_unit().

2019-08-21ipv6/addrconf: allow adding multicast addr if IFA_F_MCAUTOJOIN is setHangbin Liu1-1/+2
In commit 93a714d6b53d ("multicast: Extend ip address command to enable multicast group join/leave on") we added a new flag IFA_F_MCAUTOJOIN to make user able to add multicast address on ethernet interface. This works for IPv4, but not for IPv6. See the inet6_addr_add code. static int inet6_addr_add() { ... if (cfg->ifa_flags & IFA_F_MCAUTOJOIN) { ipv6_mc_config(net->ipv6.mc_autojoin_sk, true...) } ifp = ipv6_add_addr(idev, cfg, true, extack); <- always fail with maddr if (!IS_ERR(ifp)) { ... } else if (cfg->ifa_flags & IFA_F_MCAUTOJOIN) { ipv6_mc_config(net->ipv6.mc_autojoin_sk, false...) } } But in ipv6_add_addr() it will check the address type and reject multicast address directly. So this feature is never worked for IPv6. We should not remove the multicast address check totally in ipv6_add_addr(), but could accept multicast address only when IFA_F_MCAUTOJOIN flag supplied. v2: update commit description Fixes: 93a714d6b53d ("multicast: Extend ip address command to enable multicast group join/leave on") Reported-by: Jianlin Shi <[email protected]> Signed-off-by: Hangbin Liu <[email protected]> Signed-off-by: David S.

2019-08-21net: dsa: bcm_sf2: Do not configure PHYLINK on CPU portFlorian Fainelli1-2/+8
The SF2 binding does not specify that the CPU port should have properties mandatory for successfully instantiating a PHYLINK object. As such, there will be missing properties (including fixed-link) and when attempting to validate and later configure link modes, we will have an incorrect set of parameters (interface, speed, duplex). Simply prevent the CPU port from being configured through PHYLINK since bcm_sf2_imp_setup() takes care of that already.

2019-08-21drm/amd/display: Calculate bpc based on max_requested_bpcNicholas Kazlauskas1-2/+14
[Why] The only place where state->max_bpc is updated on the connector is at the start of atomic check during drm_atomic_connector_check. It isn't updated when adding the connectors to the atomic state after the fact. It also doesn't necessarily reflect the right value when called in amdgpu during mode validation outside of atomic check. This can cause the wrong bpc to be used even if the max_requested_bpc is the correct value. [How] Don't rely on state->max_bpc reflecting the real bpc value and just do the min(...) based on display info bpc and max_requested_bpc.

This is an issue as cpsw_remove_dt() uses platform_get_drvdata() to retrieve the cpsw_common data and leds to a NULL pointer exception.

2019-08-21selftests/bpf: fix test_btf_dump with O=Ilya Leoshkevich2-0/+10
test_btf_dump fails when run with O=, because it needs to access source files and assumes they live in ./progs/, which is not the case in this scenario. Fix by instructing kselftest to copy btf_dump_test_case_*.c files to the test directory. Since kselftest does not preserve directory structure, adjust the test to look in ./progs/ and then in ./.

2019-08-21selftests/bpf: fix test_cgroup_storage on s390Ilya Leoshkevich1-3/+3
test_cgroup_storage fails on s390 with an assertion failure: packets are dropped when they shouldn't. The problem is that BPF_DW packet count is accessed as BPF_W with an offset of 0, which is not correct on big-endian machines. Since the point of this test is not to verify narrow loads/stores, simply use BPF_DW when working with packet counts.

2019-08-21modules: page-align module section allocations only for arches supporting ↵He Zhe1-1/+6
strict module rwx We should keep the case of "#define debug_align(X) (X)" for all arches without CONFIG_HAS_STRICT_MODULE_RWX ability, which would save people, who are sensitive to system size, a lot of memory when using modules, especially for embedded systems. This is also the intention of the original #ifdef... statement and still valid for now. Note that this still keeps the effect of the fix of the following commit, 38f054d549a8 ("modules: always page-align module section allocations"), since when CONFIG_ARCH_HAS_STRICT_MODULE_RWX is enabled, module pages are aligned.

2019-08-21Revert "cfg80211: fix processing world regdomain when non modular"Hodaszi, Robert1-1/+1
This reverts commit 96cce12ff6e0 ("cfg80211: fix processing world regdomain when non modular"). Re-triggering a reg_process_hint with the last request on all events, can make the regulatory domain fail in case of multiple WiFi modules. On slower boards (espacially with mdev), enumeration of the WiFi modules can end up in an intersected regulatory domain, and user cannot set it with 'iw reg set' anymore. This is happening, because: - 1st module enumerates, queues up a regulatory request - request gets processed by __reg_process_hint_driver(): - checks if previous was set by CORE -> yes - checks if regulator domain changed -> yes, from '00' to e.g. 'US' -> sends request to the 'crda' - 2nd module enumerates, queues up a regulator request (which triggers the reg_todo() work) - reg_todo() -> reg_process_pending_hints() sees, that the last request is not processed yet, so it tries to process it again. __reg_process_hint driver() will run again, and: - checks if the last request's initiator was the core -> no, it was the driver (1st WiFi module) - checks, if the previous initiator was the driver -> yes - checks if the regulator domain changed -> yes, it was '00' (set by core, and crda call did not return yet), and should be changed to 'US' ------> __reg_process_hint_driver calls an intersect Besides, the reg_process_hint call with the last request is meaningless since the crda call has a timeout work. If that timeout expires, the first module's request will lost.

2019-08-21cfg80211: Fix Extended Key ID key install checksAlexander Wetzel1-9/+14
Fix two shortcomings in the Extended Key ID API: 1) Allow the userspace to install pairwise keys using keyid 1 without NL80211_KEY_NO_TX set. This allows the userspace to install and activate pairwise keys with keyid 1 in the same way as for keyid 0, simplifying the API usage for e.g. FILS and FT key installs. 2) IEEE 802.11 - 2016 restricts Extended Key ID usage to CCMP/GCMP ciphers in IEEE 802.11 - 2016 "9.4.2.25.4 RSN capabilities". Enforce that when installing a key.

2019-08-21ALSA: usb-audio: Fix invalid NULL check in snd_emuusb_set_samplerate()Takashi Iwai1-4/+4
The quirk function snd_emuusb_set_samplerate() has a NULL check for the mixer element, but this is useless in the current code. It used to be a check against mixer->id_elems[unitid] but it was changed later to the value after mixer_eleme_list_to_info() which is always non-NULL due to the container_of() usage. This patch fixes the check before the conversion. While we're at it, correct a typo in the comment in the function, too.
