* Update copyright headersDmitry V. Levin2022-01-0915-15/+15
| | | | | Headers updated automatically using maint/update_copyright_years.sh script.
* Fix preprocessor indentationDmitry V. Levin2022-01-091-5/+5
| | | | | | | | | Indent the C preprocessor directives to reflect their nesting using the following script: $ cppi -l $(git grep -El '^[[:space:]]*#[[:space:]]*(if|ifdef|ifndef|elif|else|endif|define|pragma)[[:space:]]' src tests |grep -v '\.sh$') |while read f; do cppi < "$f" > "$f".cppi; mv "$f".cppi "$f" done
* net: remove PACKET_ADD_MEMBERSHIP #ifdef guardsEugene Syromyatnikov2022-01-092-9/+6
| | | | | | | | | Both PACKET_ADD_MEMBERSHIP and struct packet_mreq are provided by <linux/if_packet.h> at least since Linux 2.6.12. * src/xlat/packet_mreq_type.in: Add #value_indexed, provide fallback definitions. * src/net.c: Remove PACKET_ADD_MEMBERSHIP #ifdef guards.
* net: remove PACKET_RX_RING and PACKET_TX_RING #ifdef guardsEugene Syromyatnikov2022-01-091-6/+0
| | | | | | | | | All of them as well as struct tpacket_req are provided by <linux/if_packet.h> at least since Linux 2.6.12. * src/net.c: Remove PACKET_RX_RING and PACKET_TX_RING #ifdef guards. Complements: v5.15~139 "xlat: add fallback values to sock_packet_options"
* net: remove IPV6_ADD_MEMBERSHIP and IPV6_{JOIN,LEAVE}_ANYCAST guardsEugene Syromyatnikov2022-01-091-8/+0
| | | | | | | | | | | | All of them are present since at least Linux 2.6.12 and glibc-2.3.3~616. * src/net.c [!IPV6_ADD_MEMBERSHIP] (print_mreq6): Enable function declaration. [!IPV6_ADD_MEMBERSHIP || !IPV6_JOIN_ANYCAST || !IPV6_LEAVE_ANYCAST] (print_setsockopt): Enable case IPV6_ADD_MEMBERSHIP, case IPV6_DROP_MEMBERSHIP, case IPV6_JOIN_ANYCAST, and case IPV6_LEAVE_ANYCAST. Complements: v5.15~140 "xlat: add fallback values to sock_ipv6_options"
* Remove MCAST_JOIN_GROUP #ifdef guardsEugene Syromyatnikov2022-01-092-12/+0
| | | | | | | | | | | | | | These are long defined (before Linux 2.6.12 and since glibc-2.3.4~748), so there seems to be no need to conditionalise on them. * src/net.c [!MCAST_JOIN_GROUP]: Enable case MCAST_JOIN_GROUP and case MCAST_LEAVE_GROUP. * src/print_group_req.c [!MCAST_JOIN_GROUP]: Enable DEF_MPERS_TYPE(struct_group_req) include, struct_group_req typedef, and print_group_req function. Complements: v5.15~141 "xlat: add fallback values to sock_ip_options" Complements: v5.15~140 "xlat: add fallback values to sock_ipv6_options"
* net: remove IP_ADD_MEMBERSHIP #ifdef guardsEugene Syromyatnikov2022-01-091-4/+0
| | | | | | | | | | | | | IP_ADD_MEMBERSHIP and IP_DROP_MEMBERSHIP are always defined since commit v5.15~141 "xlat: add fallback values to sock_ip_options", and the struct ip_mreq definition is present in UAPI since at least v2.6.12, so simply remove the #ifdef guards. * src/net.c [!IP_ADD_MEMBERSHIP] (print_mreq): Provide definition. [!IP_ADD_MEMBERSHIP] (print_setsockopt): Enable case IP_ADD_MEMBERSHIP and case IP_DROP_MEMBERSHIP. Complements: v5.15~141 "xlat: add fallback values to sock_ip_options"
* net: remove PACKET_STATISTICS #ifdef guardsEugene Syromyatnikov2022-01-091-4/+0
| | | | | | | | | | | | The constant is always defined since v5.15~139 "xlat: add fallback values to sock_packet_options", and the decoder function does not require any extra definitions, so the #fidef guards are now superficial. * src/net.c [!PACKET_STATISTICS] (print_tpacket_stats): Make available. [!PACKET_STATISTICS] (print_getsockopt) <case SOL_PACKET: case PACKET_STATISTICS>: Call print_tpacket_stats. Complements: v5.15~139 "xlat: add fallback values to sock_packet_options"
* net: initialise struct icmp_filter read buffer with ~0Eugene Syromyatnikov2022-01-091-1/+1
| | | | | | | Since only the unset bits are printed, this avoids printing of bits not returned by the kernel when a short read is performed. * src/net.c (print_icmp_filter): Set filter.data to ~0U.
* net: fix SO_ERROR socket option len clampingEugene Syromyatnikov2022-01-091-1/+1
| | | | | | | | | | | Looks like a typo: err is set if len is too big instead of len. Fixes possible out-of-bounds read on umoven_or_printaddr when len is too big. * src/net.c (print_get_error) <if (len > sizeof(err))>: Set len to sizeof(err) and not err. Fixes: v4.26~45 "net: enhance decoding of getsockopt(SO_ERROR)"
