2019-02-04net: phy: fixed-phy: Drop GPIO from fixed_phy_add()Linus Walleij1-1/+1
All users of the fixed_phy_add() pass -1 as GPIO number to the fixed phy driver, and all users of fixed_phy_register() pass -1 as GPIO number as well, except for the device tree MDIO bus. Any new users should create a proper device and pass the GPIO as a descriptor associated with the device so delete the GPIO argument from the calls and drop the code looking requesting a GPIO in fixed_phy_add(). In fixed phy_register(), investigate the "fixed-link" node and pick the GPIO descriptor from "link-gpios" if this property exists. Move the corresponding code out of of_mdio.c as the fixed phy code anyways requires OF to be in use.

2019-01-30fs/dcache: Track & report number of negative dentriesWaiman Long1-10/+16
The current dentry number tracking code doesn't distinguish between positive & negative dentries. It just reports the total number of dentries in the LRU lists. As excessive number of negative dentries can have an impact on system performance, it will be wise to track the number of positive and negative dentries separately. This patch adds tracking for the total number of negative dentries in the system LRU lists and reports it in the 5th field in the /proc/sys/fs/dentry-state file. The number, however, does not include negative dentries that are in flight but not in the LRU yet as well as those in the shrinker lists which are on the way out anyway. The number of positive dentries in the LRU lists can be roughly found by subtracting the number of negative dentries from the unused count. Matthew Wilcox had confirmed that since the introduction of the dentry_stat structure in 2.1.60, the dummy array was there, probably for future extension. They were not replacements of pre-existing fields. So no sane applications that read the value of /proc/sys/fs/dentry-state will do dummy thing if the last 2 fields of the sysctl parameter are not zero. IOW, it will be safe to use one of the dummy array entry for negative dentry count. Signed-off-by: Waiman Long <longman@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-01-29 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Teach verifier dead code removal, this also allows for optimizing / removing conditional branches around dead code and to shrink the resulting image. Code store constrained architectures like nfp would have hard time doing this at JIT level, from Jakub. 2) Add JMP32 instructions to BPF ISA in order to allow for optimizing code generation for 32-bit sub-registers. Evaluation shows that this can result in code reduction of ~5-20% compared to 64 bit-only code generation. Also add implementation for most JITs, from Jiong. 3) Add support for __int128 types in BTF which is also needed for vmlinux's BTF conversion to work, from Yonghong. 4) Add a new command to bpftool in order to dump a list of BPF-related parameters from the system or for a specific network device e.g. in terms of available prog/map types or helper functions, from Quentin. 5) Add AF_XDP sock_diag interface for querying sockets from user space which provides information about the RX/TX/fill/completion rings, umem, memory usage etc, from Björn. 6) Add skb context access for skb_shared_info->gso_segs field, from Eric. 7) Add support for testing flow dissector BPF programs by extending existing BPF_PROG_TEST_RUN infrastructure, from Stanislav. 8) Split BPF kselftest's test_verifier into various subgroups of tests in order better deal with merge conflicts in this area, from Jakub. 9) Add support for queue/stack manipulations in bpftool, from Stanislav. 10) Document BTF, from Yonghong. 11) Dump supported ELF section names in libbpf on program load failure, from Taeung. 12) Silence a false positive compiler warning in verifier's BTF handling, from Peter. 13) Fix help string in bpftool's feature probing, from Prashant. 14) Remove duplicate includes in BPF kselftests, from Yue. ==================== Signed-off-by: David S.

2019-01-22net: introduce a knob to control whether to inherit devconf configCong Wang1-0/+14
There have been many people complaining about the inconsistent behaviors of IPv4 and IPv6 devconf when creating new network namespaces. Currently, for IPv4, we inherit all current settings from init_net, but for IPv6 we reset all setting to default. This patch introduces a new /proc file /proc/sys/net/core/devconf_inherit_init_net to control the behavior of whether to inhert sysctl current settings from init_net. This file itself is only available in init_net. As demonstrated below: Initial setup in init_net: # cat /proc/sys/net/ipv4/conf/all/rp_filter 2 # cat /proc/sys/net/ipv6/conf/all/accept_dad 1 Default value 0 (current behavior): # ip netns del test # ip netns add test # ip netns exec test cat /proc/sys/net/ipv4/conf/all/rp_filter 2 # ip netns exec test cat /proc/sys/net/ipv6/conf/all/accept_dad 0 Set to 1 (inherit from init_net): # echo 1 > /proc/sys/net/core/devconf_inherit_init_net # ip netns del test # ip netns add test # ip netns exec test cat /proc/sys/net/ipv4/conf/all/rp_filter 2 # ip netns exec test cat /proc/sys/net/ipv6/conf/all/accept_dad 1 Set to 2 (reset to default): # echo 2 > /proc/sys/net/core/devconf_inherit_init_net # ip netns del test # ip netns add test # ip netns exec test cat /proc/sys/net/ipv4/conf/all/rp_filter 0 # ip netns exec test cat /proc/sys/net/ipv6/conf/all/accept_dad 0 Set to a value out of range (invalid): # echo 3 > /proc/sys/net/core/devconf_inherit_init_net -bash: echo: write error: Invalid argument # echo -1 > /proc/sys/net/core/devconf_inherit_init_net -bash: echo: write error: Invalid argument Reported-by: Zhu Yanjun <Yanjun.Zhu@windriver.com> Reported-by: Tonghao Zhang <xiangxia.m.yue@gmail.com> Cc: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: Cong Wang <xiyou.wangcong@gmail.com> Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Acked-by: Tonghao Zhang <xiangxia.m.yue@gmail.com> Signed-off-by: David S.
