Daniel Borkmann says: ==================== pull-request: bpf 2021-12-16 We've added 15 non-merge commits during the last 7 day(s) which contain a total of 12 files changed, 434 insertions(+), 30 deletions(-). The main changes are: 1) Fix incorrect verifier state pruning behavior for <8B register spill/fill, from Paul Chaignon. 2) Fix x86-64 JIT's extable handling for fentry/fexit when return pointer is an ERR_PTR(), from Alexei Starovoitov. 3) Fix 3 different possibilities that BPF verifier missed where unprivileged could leak kernel addresses, from Daniel Borkmann. 4) Fix xsk's poll behavior under need_wakeup flag, from Magnus Karlsson. 5) Fix an oob-write in test_verifier due to a missed MAX_NR_MAPS bump, from Kumar Kartikeya Dwivedi. 6) Fix a race in test_btf_skc_cls_ingress selftest, from Martin KaFai Lau. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf: bpf, selftests: Fix racing issue in btf_skc_cls_ingress test selftest/bpf: Add a test that reads various addresses. bpf: Fix extable address check. bpf: Fix extable fixup offset. bpf, selftests: Add test case trying to taint map value pointer bpf: Make 32->64 bounds propagation slightly more robust bpf: Fix signed bounds propagation after mov32 bpf, selftests: Update test case for atomic cmpxchg on r0 with pointer bpf: Fix kernel address leakage in atomic cmpxchg's r0 aux reg bpf, selftests: Add test case for atomic fetch on spilled pointer bpf: Fix kernel address leakage in atomic fetch selftests/bpf: Fix OOB write in test_verifier xsk: Do not sleep in poll() when need_wakeup set selftests/bpf: Tests for state pruning with u32 spill/fill bpf: Fix incorrect state pruning for <8B spill/fill ==================== Link: https://lore.kernel.org/r/20211216210005.13815-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
