samples/bpf: Fix broken tracex1 due to kprobe argument change

2021-05-19T08:29:34+00:00

[ Upstream commit 137733d08f4ab14a354dacaa9a8fc35217747605 ] >From commit c0bbbdc32feb ("__netif_receive_skb_core: pass skb by reference"), the first argument passed into __netif_receive_skb_core has changed to reference of a skb pointer. This commit fixes by using bpf_probe_read_kernel.

kfifo: fix ternary sign extension bugs

2021-05-14T08:50:19+00:00

[ Upstream commit 926ee00ea24320052b46745ef4b00d91c05bd03d ] The intent with this code was to return negative error codes but instead it returns positives. The problem is how type promotion works with ternary operations. These functions return long, "ret" is an int and "copied" is a u32. The negative error code is first cast to u32 so it becomes a high positive and then cast to long where it's still a positive. We could fix this by declaring "ret" as a ssize_t but let's just get rid of the ternaries instead.

samples/bpf: Fix possible hang in xdpsock with multiple threads

2020-12-10T22:13:43+00:00

Fix a possible hang in xdpsock that can occur when using multiple threads. In this case, one or more of the threads might get stuck in the while-loop in tx_only after the user has signaled the main thread to stop execution. In this case, no more Tx packets will be sent, so a thread might get stuck in the aforementioned while-loop. Fix this by introducing a test inside the while-loop to check if the benchmark has been terminated. If so, return from the function.
