Package: libc6-dev Version: 2.13-38 Severity: wishlist Tags: upstream patch
(submitting this on behalf of the CC target, since it blocks his email?) Though supported in the default kernel, the defines for the TCP_THIN* and several other fully supported TCP socket options are missing from tcp.h. This makes it very hard to build applications that utilize these features. I have backported the relevant patch from upstream eglibc and included it below. diff -urB eglibc-2.13.orig/sysdeps/gnu/netinet/tcp.h eglibc-2.13/sysdeps/gnu/netinet/tcp.h --- eglibc-2.13.orig/sysdeps/gnu/netinet/tcp.h 2007-10-15 16:14:17.000000000 -0400 +++ eglibc-2.13/sysdeps/gnu/netinet/tcp.h 2013-04-16 15:10:29.000000000 -0400 @@ -37,20 +37,24 @@ /* * User-settable options (used with setsockopt). */ -#define TCP_NODELAY 1 /* Don't delay send to coalesce packets */ -#define TCP_MAXSEG 2 /* Set maximum segment size */ -#define TCP_CORK 3 /* Control sending of partial frames */ -#define TCP_KEEPIDLE 4 /* Start keeplives after this period */ -#define TCP_KEEPINTVL 5 /* Interval between keepalives */ -#define TCP_KEEPCNT 6 /* Number of keepalives before death */ -#define TCP_SYNCNT 7 /* Number of SYN retransmits */ -#define TCP_LINGER2 8 /* Life time of orphaned FIN-WAIT-2 state */ -#define TCP_DEFER_ACCEPT 9 /* Wake up listener only when data arrive */ -#define TCP_WINDOW_CLAMP 10 /* Bound advertised window */ -#define TCP_INFO 11 /* Information about this connection. */ -#define TCP_QUICKACK 12 /* Bock/reenable quick ACKs. */ -#define TCP_CONGESTION 13 /* Congestion control algorithm. */ -#define TCP_MD5SIG 14 /* TCP MD5 Signature (RFC2385) */ +#define TCP_NODELAY 1 /* Don't delay send to coalesce packets */ +#define TCP_MAXSEG 2 /* Set maximum segment size */ +#define TCP_CORK 3 /* Control sending of partial frames */ +#define TCP_KEEPIDLE 4 /* Start keeplives after this period */ +#define TCP_KEEPINTVL 5 /* Interval between keepalives */ +#define TCP_KEEPCNT 6 /* Number of keepalives before death */ +#define TCP_SYNCNT 7 /* Number of SYN retransmits */ +#define TCP_LINGER2 8 /* Life time of orphaned FIN-WAIT-2 state */ +#define TCP_DEFER_ACCEPT 9 /* Wake up listener only when data arrive */ +#define TCP_WINDOW_CLAMP 10 /* Bound advertised window */ +#define TCP_INFO 11 /* Information about this connection. */ +#define TCP_QUICKACK 12 /* Bock/reenable quick ACKs. */ +#define TCP_CONGESTION 13 /* Congestion control algorithm. */ +#define TCP_MD5SIG 14 /* TCP MD5 Signature (RFC2385) */ +#define TCP_COOKIE_TRANSACTIONS 15 /* TCP Cookie Transactions */ +#define TCP_THIN_LINEAR_TIMEOUTS 16 /* Use linear timeouts for thin streams*/ +#define TCP_THIN_DUPACK 17 /* Fast retrans. after 1 dupack */ +#define TCP_USER_TIMEOUT 18 /* How long for loss retry before timeout */ #ifdef __USE_MISC # include <sys/types.h> @@ -173,7 +177,8 @@ # define TCPI_OPT_TIMESTAMPS 1 # define TCPI_OPT_SACK 2 # define TCPI_OPT_WSCALE 4 -# define TCPI_OPT_ECN 8 +# define TCPI_OPT_ECN 8 /* ECN was negociated at TCP session init */ +# define TCPI_OPT_ECN_SEEN 16 /* we received at least one packet with ECT */ /* Values for tcpi_state. */ enum tcp_ca_state @@ -241,6 +246,33 @@ u_int8_t tcpm_key[TCP_MD5SIG_MAXKEYLEN]; /* Key (binary). */ }; +/* For cookie transactions socket options. */ +#define TCP_COOKIE_MIN 8 /* 64-bits */ +#define TCP_COOKIE_MAX 16 /* 128-bits */ +#define TCP_COOKIE_PAIR_SIZE (2*TCP_COOKIE_MAX) + +/* Flags for both getsockopt and setsockopt */ +#define TCP_COOKIE_IN_ALWAYS (1 << 0) /* Discard SYN without cookie */ +#define TCP_COOKIE_OUT_NEVER (1 << 1) /* Prohibit outgoing cookies, + * supercedes everything. */ + +/* Flags for getsockopt */ +#define TCP_S_DATA_IN (1 << 2) /* Was data received? */ +#define TCP_S_DATA_OUT (1 << 3) /* Was data sent? */ + +#define TCP_MSS_DEFAULT 536U /* IPv4 (RFC1122, RFC2581) */ +#define TCP_MSS_DESIRED 1220U /* IPv6 (tunneled), EDNS0 (RFC3226) */ + +struct tcp_cookie_transactions +{ + u_int16_t tcpct_flags; + u_int8_t __tcpct_pad1; + u_int8_t tcpct_cookie_desired; + u_int16_t tcpct_s_data_desired; + u_int16_t tcpct_used; + u_int8_t tcpct_value[TCP_MSS_DEFAULT]; +}; + #endif /* Misc. */ #endif /* netinet/tcp.h */ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
