* add new IP_BIND_ADDRESS_NO_PORT and IPPROTO_MPLS to netinet/in.hSzabolcs Nagy2016-01-241-0/+2
| | | | | | | | | IP_BIND_ADDRESS_NO_PORT is a SOL_IP socket option to delay src port allocation until connect in case src ip is set with bind(port=0). new in linux v4.2, commit 90c337da1524863838658078ec34241f45d8394d IPPROTO_MPLS protocol number for mpls over ip. new in linux v4.2, commit 730fc4371333636a00fed32c587fc1e85c5367e2
* update netinet/tcp.h for linux v4.2Szabolcs Nagy2016-01-241-0/+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
* netinet/tcp: Add TCPOPT, TCPOLEN constantsKylie McClain2016-01-171-0/+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.
* fix netinet/ether.h for c++Szabolcs Nagy2015-05-081-0/+8
|
* add IPTOS_CLASS_* macros to netinet/ip.hSzabolcs Nagy2015-05-011-0/+12
| | | | | These macros were introduced in glibc 2.12 to follow RFC 2474 which deprecates "IP Precedence" in favor of "Class Selector Codepoints".
* add IP_CHECKSUM socket option to netinet/in.hSzabolcs Nagy2015-04-171-0/+1
| | | | new in linux v4.0, commit ad6f939ab193750cc94a265f58e007fb598c97b7
* add new IPV6_AUTOFLOWLABEL socket option in netinet/in.hSzabolcs Nagy2014-10-081-0/+1
| | | | | added in linux v3.17 commit 753a2ad54ef45e3417a9d49537c2b42b04a2e1be enables automatic flow label generation on transmit
* add pacing rate information to the tcp_info struct in tcp.hSzabolcs Nagy2014-07-201-0/+2
| | | | | used by monitoring applications such as ss from iproute2 introduced in linux 3.15 commit 977cb0ecf82eb6d15562573c31edebf90db35163
* add new ethernet packet types ETH_P_80221, ETH_P_LOOPBACKSzabolcs Nagy2014-07-201-2/+4
| | | | | | | | | | ETH_P_80221 is ethertype for IEEE Std 802.21 - Media Independent Handover Protocol introduced in linux 3.15 commit b62faf3cdc875a1ac5a10696cf6ea0b12bab1596 ETH_P_LOOPBACK is the correct packet type for loopback in IEEE 802.3* introduced in linux 3.15 commit 61ccbb684421d374fdcd7cf5d6b024b06f03ce4e some defines were shuffled to be in ascending order and match the kernel header
* update netinet/in.h to match the current kernel uapiSzabolcs Nagy2014-05-301-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | from linux/in.h and linux/in6.h uapi headers the following missing socket options were added: IP_NODEFRAG - used with customized ipv4 headers IPV6_RECVPATHMTU - for ipv6 path mtu IPV6_PATHMTU - for ipv6 path mtu IPV6_DONTFRAG - for ipv6 path mtu IPV6_ADDR_PREFERENCES - RFC5014 Source Address Selection IPV6_MINHOPCOUNT - RFC5082 Generalized TTL Security Mechanism IPV6_ORIGDSTADDR - used by tproxy IPV6_RECVORIGDSTADDR - used by tproxy IPV6_TRANSPARENT - used by tproxy IPV6_UNICAST_IF - ipv6 version of IP_UNICAST_IF and socket option values: IP_PMTUDISC_OMIT - value for IP_MTU_DISCOVER option, new in linux 3.14 IPV6_PMTUDISC_OMIT - same for IPV6_MTU_DISCOVER IPV6_PMTUDISC_INTERFACE - ipv6 version of IP_PMTUDISC_INTERFACE IPV6_PREFER_* - flags for IPV6_ADDR_PREFERENCES not added: ipv6 flow info and flow label related definitions. (it's unclear if libc should define these and namespace polluting type name is involved so they are not provided for now)
* in.h: new IP_MTU_DISCOVER mode IP_PMTUDISC_INTERFACESzabolcs Nagy2014-02-251-0/+1
| | | | | introduced in linux v3.13, 482fc6094afad572a4ea1fd722e7b11ca72022a0 to mitigate dns cache poisoning via fragmentation
* if_ether.h: new ethernet protocol typeSzabolcs Nagy2014-02-251-0/+1
| | | | | for High-availability Seamless Redundancy (HSR) specified in IEC 62439-3 new in linux v3.13, f421436a591d34fa5279b54a96ac07d70250cc8d
* add parens when bit and arith ops are mixed in macros in public headersSzabolcs Nagy2014-02-111-1/+1
| | | | | another commit to silence gcc warnings (-Wparentheses) for standard headers. changed macros: LOG_UPTO, IN6_ARE_ADDR_EQUAL
* reduce namespace pollution in netinet/udp.hRich Felker2014-02-051-7/+10
| | | | | | | | | | | the affected part of the header is responsible for providing both GNU and BSD versions of the udphdr structure. previously, the namespace-polluting GNU names were always used for the actual struct members, and the BSD names, which are named in a manner resembling a sane namespace, were always macros defined to expand to the GNU names. now, unless _GNU_SOURCE is defined, the BSD names are used as the actual structure members, and the macros and GNU names only come into play when the application requests them.
* fix use of legacy u_intN_t types in netinet/tcp.hRich Felker2014-02-051-73/+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.
* add support for BSD struct tcphdr in netinet/tcp.hRich Felker2014-02-051-4/+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.
* fix remaining known namespace violations for netinet/in.hRich Felker2014-01-081-22/+14
| | | | | | | | | | | | | | | | | | | | the imr_, imsf_, ip6_, ip6m_, ipi_, ipi6_, SCM_, and SOL_ prefixes are not in the reserved namespace for this header. thus the constants and structures using them need to be protected under appropriate feature test macros. this also affects some headers which are permitted to include netinet/in.h, particularly netdb.h and arpa/inet.h. the SOL_ macros are moved to sys/socket.h where they are in the reserved namespace (SO*). they are still accessible via netinet/in.h since it includes sys/socket.h implicitly (which is permitted). the SCM_SRCRT macro is simply removed, since the definition used for it, IPV6_RXSRCRT is not defined anywhere. it could be re-added, this time in sys/socket.h, if the appropriate value can be determined; however, given that the erroneous definition was not caught, it is unlikely that any software actually attempts to use SCM_SRCRT.
* add netinet/igmp.h and multicast groups to netinet/in.hRich Felker2013-12-202-0/+50
| | | | based on patch by Timo Teräs.
* add TCP_INFO and TCP_MD5SIG socket option related structuresTimo Teräs2013-12-201-0/+58

* add TCP_NOTSENT_LOWAT tcp socket option, new in linux v3.12Szabolcs Nagy2013-11-231-0/+1
|
* add linux tcp state enumsTimo Teräs2013-11-231-0/+12
|
* add multicast structures from RFC 3678 to netinet/in.hTimo Teräs2013-11-231-1/+42
| | | | | and use _GNU_SOURCE || _BSD_SOURCE guards for all of the RFC 3678 namespace polluting things like glibc/uclibc does.
* netinet/in.h: add missing IP protocol numbers from the linux uapi headersSzabolcs Nagy2013-09-151-0/+2
|
* only expose struct tcphdr under _GNU_SOURCERich Felker2013-08-301-1/+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.
* add struct tcphdr in netinet/tcp.hRich Felker2013-08-301-0/+33
|
* add if_ether.h constants ETH_P_802_3_MIN and ETH_P_BATMANSzabolcs Nagy2013-07-241-0/+3
| | | | | see linux commits 4f99ad51292078cc47343c17d3870764588cff73 and e5c5d22e8dcf7c2d430336cbf8e180bd38e8daf1
* remove TCP_COOKIE_TRANSACTIONS from tcp.hSzabolcs Nagy2013-07-241-1/+0
| | | | removed in linux-v3.10 in commit 1a2c6181c4a1922021b4d7df373bba612c3e5f04
* refactor headers, especially alltypes.h, and improve C++ ABI compatRich Felker2013-07-221-9/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the arch-specific bits/alltypes.h.sh has been replaced with a generic alltypes.h.in and minimal arch-specific bits/alltypes.h.in. this commit is intended to have no functional changes except: - exposing additional symbols that POSIX allows but does not require - changing the C++ name mangling for some types - fixing the signedness of blksize_t on powerpc (POSIX requires signed) - fixing the limit macros for sig_atomic_t on x86_64 - making dev_t an unsigned type (ABI matching goal, and more logical) in addition, some types that were wrongly defined with long on 32-bit archs were changed to int, and vice versa; this change is non-functional except for the possibility of making pointer types mismatch, and only affects programs that were using them incorrectly, and only at build-time, not runtime. the following changes were made in the interest of moving non-arch-specific types out of the alltypes system and into the headers they're associated with, and also will tend to improve application compatibility: - netdb.h now includes netinet/in.h (for socklen_t and uint32_t) - netinet/in.h now includes sys/socket.h and inttypes.h - sys/resource.h now includes sys/time.h (for struct timeval) - sys/wait.h now includes signal.h (for siginfo_t) - langinfo.h now includes nl_types.h (for nl_item) for the types in stdint.h: - types which are of no interest to other headers were moved out of the alltypes system. - fast types for 8- and 64-bit are hard-coded (at least for now); only the 16- and 32-bit ones have reason to vary by arch. and the following types have been changed for C++ ABI purposes; - mbstate_t now has a struct tag, __mbstate_t - FILE's struct tag has been changed to _IO_FILE - DIR's struct tag has been changed to __dirstream - locale_t's struct tag has been changed to __locale_struct - pthread_t is defined as unsigned long in C++ mode only - fpos_t now has a struct tag, _G_fpos64_t - fsid_t's struct tag has been changed to __fsid_t - idtype_t has been made an enum type (also required by POSIX) - nl_catd has been changed from long to void * - siginfo_t's struct tag has been removed - sigset_t's has been given a struct tag, __sigset_t - stack_t has been given a struct tag, sigaltstack - suseconds_t has been changed to long on 32-bit archs - [u]intptr_t have been changed from long to int rank on 32-bit archs - dev_t has been made unsigned summary of tests that have been performed against these changes: - nsz's libc-test (diff -u before and after) - C++ ABI check symbol dump (diff -u before, after, glibc) - grepped for __NEED, made sure types needed are still in alltypes - built gcc 3.4.6
* add stubs for additional legacy ether.h functionsRich Felker2013-07-011-3/+3
| | | | | | these would not be expensive to actually implement, but reading /etc/ethers does not sound like a particularly useful feature, so for now I'm leaving them as stubs.
* add ether_aton[_r] and ether_ntoa[_r] functionsRich Felker2013-06-251-0/+14
| | | | | | | based on patch by Strake with minor stylistic changes, and combined into a single file. this patch remained open for a long time due to some question as to whether ether_aton would be better implemented in terms of sscanf, and it's time something was committed, so here it is.
* adding ethernet protocol ids to if_ether.h following linuxSzabolcs Nagy2013-04-011-0/+15

* add new linux tcp socket option flags to netinet/tcp.hSzabolcs Nagy2013-04-011-0/+10
|
* SOL_TCP is nonstandard and not in the reserved namespaceRich Felker2013-01-311-2/+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.
* add missing multicast socket options to netinet/in.hSzabolcs Nagy2013-01-121-0/+17
| | | | | | based on linux headers add the missing MCAST_* options under _GNU_SOURCE as they are not in the reserved namespace (this api was originally specified by RFC 3678)
* add some new-ish IPPROTO constants that were missingRich Felker2013-01-011-0/+3

* tcp.h: add SOL_TCP, analoguous to udp.hrofl0r2012-12-061-0/+2

* add IPPROTO_MAX to in.hRich Felker2012-09-081-0/+1
|
* TCP_* is in the reserved namespace for tcp.h; make use of thatRich Felker2012-09-071-3/+4
|
* default features: make musl usable without feature test macrosRich Felker2012-09-071-0/+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.
* support _BSD_SOURCE feature test macroRich Felker2012-05-221-0/+17
| | | | | patch by Isaac Dunham. matched closely (maybe not exact) to glibc's idea of what _BSD_SOURCE should make visible.
* add missing IN6_ARE_ADDR_EQUALRich Felker2012-05-111-0/+5
| | | | | written to avoid multiple conditional jumps and avoid ugly repetitive lines in the header file.
* add one more bogus legacy headerRich Felker2012-05-101-0/+9
| | | | | | | this one is for program(s|ers) who haven't heard of uint16_t and uint32_t (which are obviously the correct types for use in such situations, as they're the argument/return types for ntohs/htons and ntohl/htonl).
* add additional compatibility union member for ipv6 addressesRich Felker2012-05-031-0/+2
| | | | in6_* is in the reserved namespace, so this is valid
* fix all missing instances of __cplusplus checks/extern "C" in headersRich Felker2011-11-101-0/+8
| | | | patch by Arvid Picciani (aep)
* fix some header typosRich Felker2011-09-201-1/+1

* add IN_LOOPBACKNET constant (nonstandard but in reserved namespace)Rich Felker2011-04-061-0/+2
|
* resolve some header namespace non-issuesRich Felker2011-02-201-2/+0
| | | | | after re-reading 2.2.2 of POSIX 2008, all of these are in the correct reserved namespaces and do not need protection.
