2018-04-05headers: untangle kmemleak.h from mm.hRandy Dunlap
Currently <linux/slab.h> #includes <linux/kmemleak.h> for no obvious reason. It looks like it's only a convenience, so remove kmemleak.h from slab.h and add <linux/kmemleak.h> to any users of kmemleak_* that don't already #include it. Also remove <linux/kmemleak.h> from source files that do not use it. This is tested on i386 allmodconfig and x86_64 allmodconfig. It would be good to run it through the 0day bot for other $ARCHes. I have neither the horsepower nor the storage space for the other $ARCHes. Update: This patch has been extensively build-tested by both the 0day bot & kisskb/ozlabs build farms. Both of them reported 2 build failures for which patches are included here (in v2). [ slab.h is the second most used header file after module.h; kernel.h is right there with slab.h. There could be some minor error in the counting due to some #includes having comments after them and I didn't combine all of those. ] [akpm@linux-foundation.org: security/keys/big_key.c needs vmalloc.h, per sfr] Link: http://lkml.kernel.org/r/e4309f98-3749-93e1-4bb7-d9501a39d015@infradead.org Link: http://kisskb.ellerman.id.au/kisskb/head/13396/ Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reviewed-by: Ingo Molnar <mingo@kernel.org> Reported-by: Michael Ellerman <mpe@ellerman.id.au> [2 build failures] Reported-by: Fengguang Wu <fengguang.wu@intel.com> [2 build failures] Reviewed-by: Andrew Morton <akpm@linux-foundation.org> Cc: Wei Yongjun <weiyongjun1@huawei.com> Cc: Luis R.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pul removal of obsolete architecture ports from Arnd Bergmann: "This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers. I have been working with the (former) maintainers for each one to ensure that my interpretation was right and the code is definitely unused in mainline kernels. Many had fond memories of working on the respective ports to start with and getting them included in upstream, but also saw no point in keeping the port alive without any users. In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. In contrast, CPU instruction sets that remain popular and have actively maintained kernel ports tend to all be used across multiple licensees. [ See the new nds32 port merged in the previous commit for the next generation of "one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem" - Linus ] The removal came out of a discussion that is now documented at https://lwn.net/Articles/748074/. Unlike the original plans, I'm not marking any ports as deprecated but remove them all at once after I made sure that they are all unused. Some architectures (notably tile, mn10300, and blackfin) are still being shipped in products with old kernels, but those products will never be updated to newer kernel releases. After this series, we still have a few architectures without mainline gcc support: - unicore32 and hexagon both have very outdated gcc releases, but the maintainers promised to work on providing something newer. At least in case of hexagon, this will only be llvm, not gcc. - openrisc, risc-v and nds32 are still in the process of finishing their support or getting it added to mainline gcc in the first place. They all have patched gcc-7.3 ports that work to some degree, but complete upstream support won't happen before gcc-8.1. Csky posted their first kernel patch set last week, their situation will be similar [ Palmer Dabbelt points out that RISC-V support is in mainline gcc since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]" This really says it all: 2498 files changed, 95 insertions(+), 467668 deletions(-) * tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: (74 commits) MAINTAINERS: UNICORE32: Change email account staging: iio: remove iio-trig-bfin-timer driver tty: hvc: remove tile driver tty: remove bfin_jtag_comm and hvc_bfin_jtag drivers serial: remove tile uart driver serial: remove m32r_sio driver serial: remove blackfin drivers serial: remove cris/etrax uart drivers usb: Remove Blackfin references in USB support usb: isp1362: remove blackfin arch glue usb: musb: remove blackfin port usb: host: remove tilegx platform glue pwm: remove pwm-bfin driver i2c: remove bfin-twi driver spi: remove blackfin related host drivers watchdog: remove bfin_wdt driver can: remove bfin_can driver mmc: remove bfin_sdh driver input: misc: remove blackfin rotary driver input: keyboard: remove bf54x driver ...

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-03-31 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add raw BPF tracepoint API in order to have a BPF program type that can access kernel internal arguments of the tracepoints in their raw form similar to kprobes based BPF programs. This infrastructure also adds a new BPF_RAW_TRACEPOINT_OPEN command to BPF syscall which returns an anon-inode backed fd for the tracepoint object that allows for automatic detach of the BPF program resp. unregistering of the tracepoint probe on fd release, from Alexei. 2) Add new BPF cgroup hooks at bind() and connect() entry in order to allow BPF programs to reject, inspect or modify user space passed struct sockaddr, and as well a hook at post bind time once the port has been allocated. They are used in FB's container management engine for implementing policy, replacing fragile LD_PRELOAD wrapper intercepting bind() and connect() calls that only works in limited scenarios like glibc based apps but not for other runtimes in containerized applications, from Andrey. 3) BPF_F_INGRESS flag support has been added to sockmap programs for their redirect helper call bringing it in line with cls_bpf based programs. Support is added for both variants of sockmap programs, meaning for tx ULP hooks as well as recv skb hooks, from John. 4) Various improvements on BPF side for the nfp driver, besides others this work adds BPF map update and delete helper call support from the datapath, JITing of 32 and 64 bit XADD instructions as well as offload support of bpf_get_prandom_u32() call. Initial implementation of nfp packet cache has been tackled that optimizes memory access (see merge commit for further details), from Jakub and Jiong. 5) Removal of struct bpf_verifier_env argument from the print_bpf_insn() API has been done in order to prepare to use print_bpf_insn() soon out of perf tool directly. This makes the print_bpf_insn() API more generic and pushes the env into private data. bpftool is adjusted as well with the print_bpf_insn() argument removal, from Jiri. 6) Couple of cleanups and prep work for the upcoming BTF (BPF Type Format). The latter will reuse the current BPF verifier log as well, thus bpf_verifier_log() is further generalized, from Martin. 7) For bpf_getsockopt() and bpf_setsockopt() helpers, IPv4 IP_TOS read and write support has been added in similar fashion to existing IPv6 IPV6_TCLASS socket option we already have, from Nikita. 8) Fixes in recent sockmap scatterlist API usage, which did not use sg_init_table() for initialization thus triggering a BUG_ON() in scatterlist API when CONFIG_DEBUG_SG was enabled. This adds and uses a small helper sg_init_marker() to properly handle the affected cases, from Prashant. 9) Let the BPF core follow IDR code convention and therefore use the idr_preload() and idr_preload_end() helpers, which would also help idr_alloc_cyclic() under GFP_ATOMIC to better succeed under memory pressure, from Shaohua. 10) Last but not least, a spelling fix in an error message for the BPF cookie UID helper under BPF sample code, from Colin. ==================== Signed-off-by: David S.

In order to enable vdev stats, appropriate feature bit will be set on extended resource config.

2018-03-29wcn36xx: Fix firmware crash due to corrupted buffer addressLoic Poulain
wcn36xx_start_tx function retrieves the buffer descriptor from the channel control queue to start filling tx buffer information. However, nothing prevents this same buffer to be concurrently accessed in a concurent tx call, leading to potential buffer coruption and firmware crash (observed during iperf test). The channel control queue should only be accessed and updated with the channel lock. Fix this issue by using a local buffer descriptor which will be copied in the thread-safe wcn36xx_dxe_tx_frame. Note that buffer descriptor size is few bytes so the introduced copy overhead is insignificant. Moreover, this allows to keep the locked section minimal.

This reverts commit 55884c045d31a29cf69db8332d1064a1b61dd159. When Ath10k is in AP mode and an unassociated STA sends a VHT action frame (Operating Mode Notification for the NSS change) periodically to AP this causes ath10k to call ath10k_station_assoc() which sends WMI_PEER_ASSOC_CMDID during NSS update. Over the time (with a certain client it can happen within 15 mins when there are over 500 of these VHT action frames) continuous calls of WMI_PEER_ASSOC_CMDID cause firmware to assert due to resource exhaust. To my knowledge setting WMI_PEER_NSS peer param itself enough to handle NSS updates and no need to call ath10k_station_assoc(). So revert the original commit from 2014 as it's unclear why the change was really needed. Now the firmware assert doesn't happen anymore. Issue observed in QCA9984 platform with firmware version:10.4-3.5.3-00053. This Change tested in QCA9984 with firmware version: 10.4-3.5.3-00053 and QCA988x platform with firmware version: 10.2.4-1.0-00036. Firmware Assert log: ath10k_pci 0002:01:00.0: firmware crashed!

We can set triggers that cause a debug data collection when something of interest happens (e.g. when too many probes are lost conscutively). Normally, this triggers don't cause the FW to be restarted, but in some cases that may be desired, so we recover from the problem. To support this, add a flag that indicates that the FW should be restarted when the trigger fires.

2018-03-28iwlwifi: mvm: Allow iwl_mvm_mac_mgd_prepare_tx() when associatedIlan Peer
The FW does not allocate quota air time for the binding of a station MAC before iwlmvm indicates that it is associated. Currently iwlmvm indicates that the MAC is associated only after hearing a beacon from the AP. In case a deauthentication frame is sent before the MAC is associated, the frame might not be sent as the corresponding binding is not scheduled. To handle such cases, set IEEE80211_HW_DEAUTH_NEED_MGD_TX_PREP in the HW flags, requesting mac80211 to call the mgd_prepare_tx() callback before transmitting a deauthentication frame if associated but no beacon was heard from the AP. In addition, do not warn in iwl_mvm_mac_mgd_prepare_tx() when already associated as now the callback can be called also when associated.
