* networking/libiproute/iplink.c: fix support for older kernelsThomas Devoogdt2024-10-061-0/+21
| | | | | | | | | | | | | | | | | | | - The CAN netlink interface has been added in Linux v2.6.31 with only 3 options [1]: CAN_CTRLMODE_LOOPBACK 0x1 /* Loopback mode */ CAN_CTRLMODE_LISTENONLY 0x2 /* Listen-only mode */ CAN_CTRLMODE_3_SAMPLES 0x4 /* Triple sampling mode */ So define the other options. - IFLA_CAN_TERMINATION has been added in Linux 4.11 [2], define it for older kernels.

| | | | | | | | | | | | gcc is being rather silly. Usues suboptimal registers, and does not realize that i and j are never negative, thus usese even _more_ registers for temporaries to sign-extend i/j to 64-bit offsets. function old new delta sp_256_mont_mul_8 155 132 -23 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | gcc does not necessarily clear upper bits in 64-bit regs if you ask it to load a 32-bit constant. Cast it to unsigned long. Better yet, hand-write loading of the constant with a smaller instruction. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* udhcp: Avoid leaking uninitialized/stale dataRuss Dill2023-10-042-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed a commit in connman: "gdhcp: Avoid leaking stack data via unitiialized variable" [1] Since gdhcp is just BusyBox udhcp with the serial numbers filed off, I checked if BusyBox udhcp has a related issue. The issue is that the get_option logic assumes any data within the memory area of the buffer is "valid". This reduces the complexity of the function at the cost of reading past the end of the actually received data in the case of specially crafted packets. This is not a problem for the udhcp_recv_kernel_packet data path as the entire memory area is zeroed. However, d4/d6_recv_raw_packet does not zero the memory. Note that a related commit [2] is not required as we are zeroing any data that can be read by the get_option function.

* udhcpd: optional BOOTP supportDenys Vlasenko2023-06-126-15/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | from Adam Goldman <adamg@pobox.com> This patch makes udhcpd respond correctly to queries from BOOTP clients. It contains the following changes: The end field, or DHCP_END option, is required in DHCP requests but optional in BOOTP requests. However, we still send an end field in all replies, because some BOOTP clients expect one in replies even if they didn't send one in the request. Requests without a DHCP_MESSAGE_TYPE are recognized as BOOTP requests and handled appropriately, instead of being discarded. We still require an RFC 1048 options field, but we allow it to be empty. Since a BOOTP client will keep using the assigned IP forever, we only send a BOOTP reply if a static lease exists for that client. BOOTP replies shouldn't contain DHCP_* options, so we omit them if there was no DHCP_MESSAGE_TYPE in the request. Options other than DHCP_* options are still sent. The options field of a BOOTP reply must be exactly 64 bytes. If we construct a reply with more than 64 bytes of options, we give up and log an error instead of sending it. udhcp_send_raw_packet already pads the options field to 64 bytes if it is too short. This implementation has been tested against an HP PA-RISC client. function old new delta .rodata 105247 105321 +74 udhcpd_main 1520 1591 +71 send_offer 419 470 +51 init_packet 81 97 +16 udhcp_init_header 75 88 +13 udhcp_scan_options 192 203 +11 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 6/0 up/down: 236/0) Total: 236 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
