When macro MACB_EXT_DESC is defined we end up with two identical return statements and just one is sufficient. Remove the extra return. Detected by CoverityScan, CID#1449361 ("Structurally dead code") Signed-off-by:Colin Ian King <colin.king@canonical.com> Acked-by:

There appears to be a missing break in the TCP_BPF_SNDCWND_CLAMP case. Currently the non-error path where val is greater than zero falls through to the default case that sets the error return to -EINVAL. Add in the missing break. Detected by CoverityScan, CID#1449376 ("Missing break in switch") Fixes: 13bf9641 ("bpf: Adds support for setting sndcwnd clamp") Signed-off-by:Daniel Borkmann <daniel@iogearbox.net> Acked-by:

The function load_bpf_file ignores the return value of load_and_attach(), so even if load_and_attach() returns an error, load_bpf_file() will return 0. Now, load_bpf_file() can call load_and_attach() multiple times and some can succeed and some could fail. I think the correct behavor is to return error on the first failed load_and_attach(). v2: Added missing SOB Signed-off-by:

Elena Reshetova says: ==================== v2 net subsystem misc refcounter conversions Changes in v2: * rebase on top of net-next * currently by default refcount_t = atomic_t (*) and uses all atomic standard operations unless CONFIG_REFCOUNT_FULL is enabled. This is a compromise for the systems that are critical on performance (such as net) and cannot accept even slight delay on the refcounter operations. This series, for various misc network components, replaces atomic_t reference counters with the new refcount_t type and API (see include/linux/refcount.h). By doing this we prevent intentional or accidental underflows or overflows that can led to use-after-free vulnerabilities. These are the last networking-related conversions with the exception of network drivers (to be send separately). Please excuse the long patch set, but seems like breaking it up won't save that much on CC list and most of the changes are trivial. The patches are fully independent and can be cherry-picked separately. In order to try with refcount functionality enabled in run-time, CONFIG_REFCOUNT_FULL must be enabled. NOTE: automatic kernel builder for some reason doesn't like all my network branches and regularly times out the builds on these branches. Suggestion for "waiting a day for a good coverage" doesn't work, as we have seen with generic network conversions. So please wait for the full report from kernel test rebot before merging further up. This has been compile-tested in 116 configs, but 71 timed out (including all s390-related configs again). I am trying to see if they can fix build coverage for me in meanwhile. * The respective change is currently merged into -next as "locking/refcount: Create unchecked atomic_t implementation". ==================== Signed-off-by: -

refcount_t type and corresponding API should be used instead of atomic_t when the variable is used as a reference counter. This allows to avoid accidental refcounter overflows that might lead to use-after-free situations. Signed-off-by:
