* 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
* 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
* 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 Felker2013-12-201-0/+5
| | | | based on patch by Timo Teräs.
* 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

* 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 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
|
* add IPPROTO_HOPOPTS to in.hRich Felker2012-09-081-0/+1
|
* add IPPROTO_MAX to in.hRich Felker2012-09-081-0/+1
|
* 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 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
|
* move invariant netinet/in.h stuff out of bits/in.hRich Felker2011-09-181-2/+147
|
* 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.
* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-121-0/+158
