2020-09-09netinet/tcp.h: update for linux v5.6Szabolcs Nagy-2/+4
TCP_NLA_TIMEOUT_REHASH queries timeout-triggered rehash attempts, tcpm_ifindex limits the scope of TCP_MD5SIG* sockopt to a device. see linux commit 32efcc06d2a15fa87585614d12d6c2308cc2d3f3 tcp: export count for rehash attempts linux commit 6b102db50cdde3ba2f78631ed21222edf3a5fb51 net: Add device index to tcp_md5sig
2020-09-09netinet/tcp.h: update tcp_info for linux v5.5Szabolcs Nagy-1/+8

tcpi_rcv_ooopack for tracking connection quality: linux commit f9af2dbbfe01def62765a58af7fbc488351893c3 tcp: Add TCP_INFO counter for packets received out-of-order tcpi_snd_wnd peer window size for diagnosing tcp performance problems: linux commit 8f7baad7f03543451af27f5380fc816b008aa1f2 tcp: Add snd_wnd to TCP_INFO
2019-12-30netinet/tcp.h: add TCP_TX_DELAY from linux v5.3Szabolcs Nagy-0/+1
see linux commit a842fe1425cb20f457abd3f8ef98b468f83ca98b tcp: add optional per socket transmit delay
2019-10-17remove indirect use of endian.h from public headersRich Felker-1/+0
building on commit 97d35a552ec5b6ddf7923dd2f9a8eb973526acea, __BYTE_ORDER is now available wherever alltypes.h is included. endian.h should not be used since, in the future, it will expose identifiers that are not in the reserved namespace for the headers which were previously using it.
2019-03-13netinet/tcp.h: add TCP_NLA_SRTT from linux v5.0Szabolcs Nagy-0/+1
smoothed RTT for SCM_TIMESTAMPING_OPT_STATS control messages. added in linux commit e8bd8fca6773ef49390269bd467bf940a0841ccf
2019-03-13netinet/tcp.h: add tcp_info fields from linux v4.19Szabolcs Nagy-0/+8
new fields for RFC 4898 tcp stats in linux tcpi_bytes_sent added in commit ba113c3aa79a7f941ac162d05a3620bdc985c58d tcpi_bytes_retrans added in commit fb31c9b9f6c85b1bad569ecedbde78d9e37cd87b tcpi_dsack_dups added in commit 7e10b6554ff2ce7f86d5d3eec3af5db8db482caa tcpi_reord_seen added in commit 7ec65372ca534217b53fd208500cf7aac223a383 The new fields change the size of a public struct and thus an ABI break, but this is how the getsockopt TCP_INFO api is designed: the tcp_info type must only be used with a length parameter in extern interfaces.

2017-11-05add SCM_TIMESTAMPING_OPT_STATS and related TCP_ enums from linux v4.10Szabolcs Nagy-0/+10

another kernel internal state exposure for checkpoint-restore. see linux commit b1ed4c4fa9a5ccf325184fd90edc50978ef6e33a
2016-07-03make brace placement in public header struct definitions consistentRich Felker-4/+2
placing the opening brace on the same line as the struct keyword/tag is the style I prefer and seems to be the prevailing practice in more recent additions. these changes were generated by the command: find include/ arch/*/bits -name '*.h' \ -exec sed -i '/^struct [^;{]*$/{N;s/\n/ /;}' {} + and subsequently checked by hand to ensure that the regex did not pick up any false positives.
2016-06-09add new tcp_info fields from linux v4.6Szabolcs Nagy-0/+4
new fields and associated linux commit: tcpi_notsent_bytes, tcpi_min_rtt cd9b266095f422267bddbec88f9098b48ea548fc tcpi_data_segs_in, tcpi_data_segs_out a44d6eacdaf56f74fad699af7f4925a5f5ac0e7f
2016-01-24update netinet/tcp.h for linux v4.2Szabolcs Nagy-0/+7
TCP_CC_INFO is a new socket option to get congestion control info without netlink (union tcp_cc_info is in linux/inet_diag.h kernel header). linux commit 6e9250f59ef9efb932c84850cd221f22c2a03c4a TCP_SAVE_SYN, TCP_SAVED_SYN socket options are for saving and getting the SYN headers of passive connections in a server application. linux commit cd8ae85299d54155702a56811b2e035e63064d3d Add new tcpi_* fields to struct tcp_info implementing RFC4898 counters. linux commit 2efd055c53c06b7e89c167c98069bab9afce7e59
2016-01-17netinet/tcp: Add TCPOPT, TCPOLEN constantsKylie McClain-0/+13
Programs such as iptables depend on these constants, which can also be found defined in other libcs. Since only TCP_* is reserved as part of tcp.h's namespace, we hide them behind _BSD_SOURCE (and therefore _DEFAULT_SOURCE) to expose them by default, but keep it standard conforming.
2014-07-20add pacing rate information to the tcp_info struct in tcp.hSzabolcs Nagy-0/+2
used by monitoring applications such as ss from iproute2 introduced in linux 3.15 commit 977cb0ecf82eb6d15562573c31edebf90db35163
2014-02-05fix use of legacy u_intN_t types in netinet/tcp.hRich Felker-73/+74
policy is to avoid using these types except where they are needed for namespace conformance. C99-style stdint.h types should be used instead.
2014-02-05add support for BSD struct tcphdr in netinet/tcp.hRich Felker-4/+41
there are two versions of this structure: the BSD version and the GNU version. previously only the GNU version was supported. the only way to support both simultaneously is with an anonymous union, which was a nonstandard extension prior to C11, so some effort is made to avoid breakage with compilers which do not support anonymous unions. this commit is based on a patch by Timo Teräs, but with some changes. in particular, the GNU version of the structure is not exposed unless _GNU_SOURCE is defined; this both avoids namespace pollution and dependency on anonymous unions in the default feature profile.
2013-12-20add TCP_INFO and TCP_MD5SIG socket option related structuresTimo Teräs-0/+58
2013-11-23add TCP_NOTSENT_LOWAT tcp socket option, new in linux v3.12Szabolcs Nagy-0/+1
2013-11-23add linux tcp state enumsTimo Teräs-0/+12
2013-08-30only expose struct tcphdr under _GNU_SOURCERich Felker-1/+3
the BSD and GNU versions of this structure differ, so exposing it in the default _BSD_SOURCE profile is possibly problematic. both versions could be simultaneously supported with anonymous unions if needed in the future, but for now, just omitting it except under _GNU_SOURCE should be safe.
2013-08-30add struct tcphdr in netinet/tcp.hRich Felker-0/+33
2013-07-24remove TCP_COOKIE_TRANSACTIONS from tcp.hSzabolcs Nagy-1/+0
removed in linux-v3.10 in commit 1a2c6181c4a1922021b4d7df373bba612c3e5f04
2013-04-01add new linux tcp socket option flags to netinet/tcp.hSzabolcs Nagy-0/+10
2013-01-31SOL_TCP is nonstandard and not in the reserved namespaceRich Felker-2/+1
alternatively, we could define it in sys/socket.h since SO* is reserved there, and tcp.h includes sys/socket.h in extensions mode. note that SOL_TCP is simply wrong and it's only here for compatibility with broken applications. the correct argument to pass for setting TCP socket options is IPPROTO_TCP, which of course has the same value as SOL_TCP but works everywhere.
2012-12-06tcp.h: add SOL_TCP, analoguous to udp.hrofl0r-0/+2
2012-09-07TCP_* is in the reserved namespace for tcp.h; make use of thatRich Felker-3/+4
2012-09-07default features: make musl usable without feature test macrosRich Felker-0/+2
the old behavior of exposing nothing except plain ISO C can be obtained by defining __STRICT_ANSI__ or using a compiler option (such as -std=c99) that predefines it. the new default featureset is POSIX with XSI plus _BSD_SOURCE. any explicit feature test macros will inhibit the default. installation docs have also been updated to reflect this change.
2012-05-22support _BSD_SOURCE feature test macroRich Felker-0/+17
patch by Isaac Dunham. matched closely (maybe not exact) to glibc's idea of what _BSD_SOURCE should make visible.
