2023-08-24riscv, bpf: Fix missing exception handling and redundant zext for LDX_B/H/WPu Lehui1-6/+3
For LDX_B/H/W, when zext has been inserted by verifier, it'll return 1, and no exception handling will continue. Also, when the offset is 12-bit value, the redundant zext inserted by the verifier is not removed. Fix both scenarios by moving down the removal of redundant zext.

Toke Høiland-Jørgensen says: ==================== samples/bpf: Remove unmaintained XDP sample utilities The samples/bpf directory in the kernel tree started out as a way of showcasing different aspects of BPF functionality by writing small utility programs for each feature. However, as the BPF subsystem has matured, the preferred way of including userspace code with a feature has become the BPF selftests, which also have the benefit of being consistently run as part of the BPF CI system. As a result of this shift, the utilities in samples/bpf have seen little love, and have slowly bitrotted. There have been sporadic cleanup patches over the years, but it's clear that the utilities are far from maintained. For XDP in particular, some of the utilities have been used as benchmarking aids when implementing new kernel features, which seems to be the main reason they have stuck around; any updates the utilities have seen have been targeted at this use case. However, as the BPF subsystem as a whole has moved on, it has become increasingly difficult to incorporate new features into these utilities because they predate most of the modern BPF features (such as kfuncs and BTF). Rather than try to update these utilities and keep maintaining them in the kernel tree, we have ported the useful features of the utilities to the xdp-tools package. In the porting process we also updated the utilities to take advantage of modern BPF features, integrated them with libxdp, and polished the user interface. As these utilities are standalone tools, maintaining them out of tree is simpler, and we plan to keep maintaining them in the xdp-tools repo. To direct users of these utilities to the right place, this series removes the utilities from samples/bpf, leaving in place only a couple of utilities whose functionality have not yet been ported to xdp-tools. The xdp-tools repository is located on Github at the following URL: https://github.com/xdp-project/xdp-tools The commits in the series removes one utility each, explaining how the equivalent functionality can be obtained with xdp-tools. v2: - Add equivalent xdp-tools commands for each removed utility v3: - Add link to xdp-tools in the README Toke Høiland-Jørgensen (7): samples/bpf: Remove the xdp_monitor utility samples/bpf: Remove the xdp_redirect* utilities samples/bpf: Remove the xdp_rxq_info utility samples/bpf: Remove the xdp1 and xdp2 utilities samples/bpf: Remove the xdp_sample_pkts utility samples/bpf: Cleanup .gitignore samples/bpf: Add note to README about the XDP utilities moved to xdp-tools samples/bpf/.gitignore | 12 - samples/bpf/Makefile | 48 +- samples/bpf/README.rst | 6 + samples/bpf/xdp1_kern.c | 100 ---- samples/bpf/xdp1_user.c | 166 ------ samples/bpf/xdp2_kern.c | 125 ----- samples/bpf/xdp_monitor.bpf.c | 8 - samples/bpf/xdp_monitor_user.c | 118 ----- samples/bpf/xdp_redirect.bpf.c | 49 -- samples/bpf/xdp_redirect_cpu.bpf.c | 539 ------------------- samples/bpf/xdp_redirect_cpu_user.c | 559 -------------------- samples/bpf/xdp_redirect_map.bpf.c | 97 ---- samples/bpf/xdp_redirect_map_multi.bpf.c | 77 --- samples/bpf/xdp_redirect_map_multi_user.c | 232 -------- samples/bpf/xdp_redirect_map_user.c | 228 -------- samples/bpf/xdp_redirect_user.c | 172 ------ samples/bpf/xdp_rxq_info_kern.c | 140 ----- samples/bpf/xdp_rxq_info_user.c | 614 ---------------------- samples/bpf/xdp_sample_pkts_kern.c | 57 -- samples/bpf/xdp_sample_pkts_user.c | 196 ------- 20 files changed, 7 insertions(+), 3536 deletions(-) delete mode 100644 samples/bpf/xdp1_kern.c delete mode 100644 samples/bpf/xdp1_user.c delete mode 100644 samples/bpf/xdp2_kern.c delete mode 100644 samples/bpf/xdp_monitor.bpf.c delete mode 100644 samples/bpf/xdp_monitor_user.c delete mode 100644 samples/bpf/xdp_redirect.bpf.c delete mode 100644 samples/bpf/xdp_redirect_cpu.bpf.c delete mode 100644 samples/bpf/xdp_redirect_cpu_user.c delete mode 100644 samples/bpf/xdp_redirect_map.bpf.c delete mode 100644 samples/bpf/xdp_redirect_map_multi.bpf.c delete mode 100644 samples/bpf/xdp_redirect_map_multi_user.c delete mode 100644 samples/bpf/xdp_redirect_map_user.c delete mode 100644 samples/bpf/xdp_redirect_user.c delete mode 100644 samples/bpf/xdp_rxq_info_kern.c delete mode 100644 samples/bpf/xdp_rxq_info_user.c delete mode 100644 samples/bpf/xdp_sample_pkts_kern.c delete mode 100644 samples/bpf/xdp_sample_pkts_user.c ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Alexei Starovoitov <[email protected]>

2023-08-24samples/bpf: Remove the xdp_sample_pkts utilityToke Høiland-Jørgensen3-256/+0
The functionality of this utility is covered by the xdpdump utility in xdp-tools. There's a slight difference in usage as the xdpdump utility's main focus is to dump packets before or after they are processed by an existing XDP program. However, xdpdump also has the --load-xdp-program switch, which will make it attach its own program if no existing program is loaded. With this, xdp_sample_pkts usage can be converted as: xdp_sample_pkts eth0 --> xdpdump --load-xdp-program eth0 To get roughly equivalent behaviour.

2023-08-24samples/bpf: Remove the xdp1 and xdp2 utilitiesToke Høiland-Jørgensen4-398/+0
The functionality of these utilities have been incorporated into the xdp-bench utility in xdp-tools. Equivalent functionality is: xdp1 eth0 --> xdp-bench drop -p parse-ip -l load-bytes eth0 xdp2 eth0 --> xdp-bench drop -p swap-macs eth0 Note that there's a slight difference in behaviour of those examples: the swap-macs operation of xdp-bench doesn't use the bpf_xdp_load_bytes() helper to load the packet data, whereas the xdp2 utility did so unconditionally. For the parse-ip action the use of bpf_xdp_load_bytes() can be selected by the '-l load-bytes' switch, with the difference that the xdp-bench utility will perform two separate calls to the helper, one to load the ethernet header and another to load the IP header; where the xdp1 utility only performed one call always loading 60 bytes of data.

2023-08-24samples/bpf: Remove the xdp_rxq_info utilityToke Høiland-Jørgensen3-757/+0
The functionality of this utility has been incorporated into the xdp-bench utility in xdp-tools, by way of the --rxq-stats argument to the 'drop', 'pass' and 'tx' commands of xdp-bench. Some examples of how to convert xdp_rxq_info invocations into equivalent xdp-bench commands: xdp_rxq_info -d eth0 --> xdp-bench pass --rxq-stats eth0 xdp_rxq_info -d eth0 -a XDP_DROP -m --> xdp-bench drop --rxq-stats -p swap-macs eth0 Signed-off-by: Toke Høiland-Jørgensen <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Alexei Starovoitov <[email protected]>
2023-08-24samples/bpf: Remove the xdp_redirect* utilitiesToke Høiland-Jørgensen9-1981/+1
These utilities have all been ported to xdp-tools as functions of the xdp-bench utility. The four different utilities in samples are incorporated as separate subcommands to xdp-bench, with most of the command line parameters left intact, except that mandatory arguments are always positional in xdp-bench. For full usage details see the --help output of each command, or the xdp-bench man page. Some examples of how to convert usage to xdp-bench are: xdp_redirect eth0 eth1 --> xdp-bench redirect eth0 eth1 xdp_redirect_map eth0 eth1 --> xdp-bench redirect-map eth0 eth1 xdp_redirect_map_multi eth0 eth1 eth2 eth3 --> xdp-bench redirect-multi eth0 eth1 eth2 eth3 xdp_redirect_cpu -d eth0 -c 0 -c 1 --> xdp-bench redirect-cpu -c 0 -c 1 eth0 xdp_redirect_cpu -d eth0 -c 0 -c 1 -r eth1 --> xdp-bench redirect-cpu -c 0 -c 1 eth0 -r redirect -D eth1 Signed-off-by: Toke Høiland-Jørgensen <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Alexei Starovoitov <[email protected]>
2023-08-24samples/bpf: Remove the xdp_monitor utilityToke Høiland-Jørgensen3-133/+1
This utility has been ported as-is to xdp-tools as 'xdp-monitor'. The only difference in usage between the samples and xdp-tools versions is that the '-v' command line parameter has been changed to '-e' in the xdp-tools version for consistency with the other utilities.

2023-08-24bonding: fix macvlan over alb bond supportHangbin Liu2-13/+4
The commit 14af9963ba1e ("bonding: Support macvlans on top of tlb/rlb mode bonds") aims to enable the use of macvlans on top of rlb bond mode. However, the current rlb bond mode only handles ARP packets to update remote neighbor entries. This causes an issue when a macvlan is on top of the bond, and remote devices send packets to the macvlan using the bond's MAC address as the destination. After delivering the packets to the macvlan, the macvlan will rejects them as the MAC address is incorrect. Consequently, this commit makes macvlan over bond non-functional. To address this problem, one potential solution is to check for the presence of a macvlan port on the bond device using netif_is_macvlan_port(bond->dev) and return NULL in the rlb_arp_xmit() function. However, this approach doesn't fully resolve the situation when a VLAN exists between the bond and macvlan. So let's just do a partial revert for commit 14af9963ba1e in rlb_arp_xmit(). As the comment said, Don't modify or load balance ARPs that do not originate locally.

After we converted the capabilities of our networking-bpf program from cap_sys_admin to cap_net_admin+cap_bpf, our networking-bpf program failed to start. Because it failed the bpf verifier, and the error log is "R3 pointer comparison prohibited". A simple reproducer as follows, SEC("cls-ingress") int ingress(struct __sk_buff *skb) { struct iphdr *iph = (void *)(long)skb->data + sizeof(struct ethhdr); if ((long)(iph + 1) > (long)skb->data_end) return TC_ACT_STOLEN; return TC_ACT_OK; } Per discussion with Yonghong and Alexei [1], comparison of two packet pointers is not a pointer leak. This patch fixes it. Our local kernel is 6.1.y and we expect this fix to be backported to 6.1.y, so stable is CCed.

Currently when ath12k_dp_cc_desc_init() is called we allocate memory to rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), during descriptor cleanup rx_descs and tx_descs memory is not freed. This is cause of memory leak. These allocated memory should be freed in ath12k_dp_cc_cleanup. In ath12k_dp_cc_desc_init(), we can save base address of rx_descs and tx_descs.

Don't queue more gc work, else we may queue the same elements multiple times. If an element is flagged as dead, this can mean that either the previous gc request was invalidated/discarded by a transaction or that the previous request is still pending in the system work queue. The latter will happen if the gc interval is set to a very low value, e.g. 1ms, and system work queue is backlogged. The sets refcount is 1 if no previous gc requeusts are queued, so add a helper for this and skip gc run if old requests are pending. Add a helper for this and skip the gc run in this case.
