The test_lru_map is relying on marking the LRU map entry via regular BPF map lookup from system call side. This is basically for simplicity reasons. Given we fixed marking entries in that case, the test needs to be fixed as well. Here we add a small drop-in replacement to retain existing behavior for the tests by marking out of the BPF program and transferring the retrieved value out via temporary map. This also adds new test cases to track the new behavior where two elements are marked, one via system call side and one via program side, where the next update then evicts the key looked up only from system call side. # ./test_lru_map nr_cpus:8 test_lru_sanity0 (map_type:9 map_flags:0x0): Pass test_lru_sanity1 (map_type:9 map_flags:0x0): Pass test_lru_sanity2 (map_type:9 map_flags:0x0): Pass test_lru_sanity3 (map_type:9 map_flags:0x0): Pass test_lru_sanity4 (map_type:9 map_flags:0x0): Pass test_lru_sanity5 (map_type:9 map_flags:0x0): Pass test_lru_sanity7 (map_type:9 map_flags:0x0): Pass test_lru_sanity8 (map_type:9 map_flags:0x0): Pass test_lru_sanity0 (map_type:10 map_flags:0x0): Pass test_lru_sanity1 (map_type:10 map_flags:0x0): Pass test_lru_sanity2 (map_type:10 map_flags:0x0): Pass test_lru_sanity3 (map_type:10 map_flags:0x0): Pass test_lru_sanity4 (map_type:10 map_flags:0x0): Pass test_lru_sanity5 (map_type:10 map_flags:0x0): Pass test_lru_sanity7 (map_type:10 map_flags:0x0): Pass test_lru_sanity8 (map_type:10 map_flags:0x0): Pass test_lru_sanity0 (map_type:9 map_flags:0x2): Pass test_lru_sanity4 (map_type:9 map_flags:0x2): Pass test_lru_sanity6 (map_type:9 map_flags:0x2): Pass test_lru_sanity7 (map_type:9 map_flags:0x2): Pass test_lru_sanity8 (map_type:9 map_flags:0x2): Pass test_lru_sanity0 (map_type:10 map_flags:0x2): Pass test_lru_sanity4 (map_type:10 map_flags:0x2): Pass test_lru_sanity6 (map_type:10 map_flags:0x2): Pass test_lru_sanity7 (map_type:10 map_flags:0x2): Pass test_lru_sanity8 (map_type:10 map_flags:0x2): Pass Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Alexei Starovoitov <ast@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.
