Loading programs that use bpf_usdt_arg() on s390x fails with: ; if (arg_num >= BPF_USDT_MAX_ARG_CNT || arg_num >= spec->arg_cnt) 128: (79) r1 = *(u64 *)(r10 -24) ; frame1: R1_w=scalar(umax=4294967295,var_off=(0x0; 0xffffffff)) R10=fp0 129: (25) if r1 > 0xb goto pc+83 ; frame1: R1_w=scalar(umax=11,var_off=(0x0; 0xf)) ... ; arg_spec = &spec->args[arg_num]; 135: (79) r1 = *(u64 *)(r10 -24) ; frame1: R1_w=scalar(umax=4294967295,var_off=(0x0; 0xffffffff)) R10=fp0 ... ; switch (arg_spec->arg_type) { 139: (61) r1 = *(u32 *)(r2 +8) R2 unbounded memory access, make sure to bounds check any such access The reason is that, even though the C code enforces that arg_num < BPF_USDT_MAX_ARG_CNT, the verifier cannot propagate this constraint to the arg_spec assignment yet. Help it by forcing r1 back to stack after comparison. Signed-off-by:Ilya Leoshkevich <iii@linux.ibm.com> Link: https://lore.kernel.org/r/20230128000650.1516334-23-iii@linux.ibm.comSigned-off-by:

s390x ABI requires the caller to zero- or sign-extend the arguments. eBPF already deals with zero-extension (by definition of its ABI), but not with sign-extension. Add a test to cover that potentially problematic area. Signed-off-by:

These functions already check that th_len < sizeof(*th), and propagating the lower bound (th_len > 0) may be challenging in complex code, e.g. as is the case with xdp_synproxy test on s390x [1]. Switch to ARG_CONST_SIZE_OR_ZERO in order to make the verifier accept code where it cannot prove that th_len > 0.

The first element of a struct bpf_cpumask is a cpumask_t. This is done to allow struct bpf_cpumask to be cast to a struct cpumask. If this element were ever moved to another field, any BPF program passing a struct bpf_cpumask * to a kfunc expecting a const struct cpumask * would immediately fail to load. Add a build-time assertion so this is assumption is captured and verified. Signed-off-by:

This patch removes the msleep(4s) during netpoll_setup() if the carrier appears instantly. Here are some scenarios where this workaround is counter-productive in modern ages: Servers which have BMC communicating over NC-SI via the same NIC as gets used for netconsole. BMC will keep the PHY up, hence the carrier appearing instantly. The link is fibre, SERDES getting sync could happen within 0.1Hz, and the carrier also appears instantly. Other than that, if a driver is reporting instant carrier and then losing it, this is probably a driver bug. Reported-by:

Magnus Karlsson says: ==================== net: xdp: execute xdp_do_flush() before napi_complete_done() Make sure that xdp_do_flush() is always executed before napi_complete_done(). This is important for two reasons. First, a redirect to an XSKMAP assumes that a call to xdp_do_redirect() from napi context X on CPU Y will be followed by a xdp_do_flush() from the same napi context and CPU. This is not guaranteed if the napi_complete_done() is executed before xdp_do_flush(), as it tells the napi logic that it is fine to schedule napi context X on another CPU. Details from a production system triggering this bug using the veth driver can be found in [1]. The second reason is that the XDP_REDIRECT logic in itself relies on being inside a single NAPI instance through to the xdp_do_flush() call for RCU protection of all in-kernel data structures. Details can be found in [2]. The drivers have only been compile-tested since I do not own any of the HW below. So if you are a maintainer, it would be great if you could take a quick look to make sure I did not mess something up. Note that these were the drivers I found that violated the ordering by running a simple script and manually checking the ones that came up as potential offenders. But the script was not perfect in any way. There might still be offenders out there, since the script can generate false negatives.

Jiri Pirko says: ==================== devlink: Cleanup params usage This patchset takes care of small cleanup of devlink params usage. Some of the patches (first 2/3) are cosmetic, but I would like to point couple of interesting ones: Patch 9 is the main one of this set and introduces devlink instance locking for params, similar to other devlink objects. That allows params to be registered/unregistered when devlink instance is registered. Patches 10-12 change mlx5 code to register non-driverinit params in the code they are related to, and thanks to patch 8 this might be when devlink instance is registered - for example during devlink reload. --- v1->v2: - Just small fix in the last patch ==================== Signed-off-by:David S.
