Subject: [PATCH bpf-next 0/3] xdpsock: allow mmap2 usage for 32bits
Date: Tue, 13 Aug 2019 13:23:15 +0300 [thread overview]
Message-ID: <20190813102318.5521-1-ivan.khoronzhuk@linaro.org> (raw)
This patchset contains several improvements for af_xdp socket umem
mappings for 32bit systems. Also, there is one more patch outside of
othis series that can be applied to another tree and related to mmap2
af_xdp umem offsets:
"mm: mmap: increase sockets maximum memory size pgoff for 32bits"
https://lkml.org/lkml/2019/8/12/549
Based on bpf-next/master
Ivan Khoronzhuk (3):
libbpf: add asm/unistd.h to xsk to get __NR_mmap2
xdp: xdp_umem: replace kmap on vmap for umem map
samples: bpf: syscal_nrs: use mmap2 if defined
