Subject: pull-request: bpf 2024-01-25
Hi David, hi Jakub, hi Paolo, hi Eric,
The following pull-request contains BPF updates for your *net* tree.
We've added 12 non-merge commits during the last 2 day(s) which contain
a total of 13 files changed, 190 insertions(+), 91 deletions(-).
The main changes are:
1) Fix bpf_xdp_adjust_tail() in context of XSK zero-copy drivers which
support XDP multi-buffer. The former triggered a NULL pointer
dereference upon shrinking, from Maciej Fijalkowski & Tirthendu Sarkar.
2) Fix a bug in riscv64 BPF JIT which emitted a wrong prologue and
epilogue for struct_ops programs, from Pu Lehui.
Please consider pulling these changes from:
git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git tags/for-netdev
Thanks a lot!
Also thanks to reporters, reviewers and testers of commits in this pull-request:
