2018-02-22netinet/tcp.h: add tcp_diag_md5sig struct from linux v4.14Szabolcs Nagy-0/+8
for querying tcp md5 signing keys. new in linux commit c03fa9bcacd9ac04595cc13f34f3445f0a5ecf13
2018-02-22sys/{mman,shm}.h: add {MAP,SHM}_HUGE_ macros from linux uapiSzabolcs Nagy-0/+26
*_HUGE_SHIFT, *_HUGE_2MB, *_HUGE_1GB are documented in the man page, so add all of the *_HUGE_* macros from linux uapi. if MAP_HUGETLB is set, top bits of the mmap flags encode the page size. see the linux commit aafd4562dfee81a40ba21b5ea3cf5e06664bc7f6 if SHM_HUGETLB is set, top bits of the shmget flags encode the page size. see the linux commit 4da243ac1cf6aeb30b7c555d56208982d66d6d33 *_HUGE_16GB is defined unsigned to avoid signed left shift ub.

socket option for kernel TLS support new in linux commit 3c4d7559159bfe1e3b94df3a657b2cda3a34e218
2018-02-22sys/socket.h: add PF_SMC from linux v4.11Szabolcs Nagy-1/+3
add AF_SMC and PF_SMC for the IBM shared memory communication protocol. new in linux commit ac7138746e14137a451f8539614cdd349153e0c0 (linux socket.h is not in uapi so this update was missed earlier)
2018-01-12add _DIRENT_HAVE_D_* macros to dirent.hRostislav Skudnov-0/+4
2018-01-09add additional uapi guards for Linux kernel header filesHauke Mehrtens-0/+10
With Linux kernel 4.16 it will be possible to guard more parts of the Linux header files from a libc. Make use of this in musl to guard all the structures and other definitions from the Linux header files which are also defined by the header files provided by musl. This will make it possible to compile source files which include both the libc headers and the kernel userspace headers. This extends the definitions done in commit 04983f227238 ("make netinet/in.h suppress clashing definitions from kernel headers")

2017-12-06adjust fopencookie structure tag for ABI-compatRich Felker-1/+1
stdio types use the struct tag names from glibc libio to match C++ ABI.
2017-12-06implement the fopencookie extension to stdioWilliam Pitcock-0/+14
notes added by maintainer: this function is a GNU extension. it was chosen over the similar BSD function funopen because the latter depends on fpos_t being an arithmetic type as part of its public API, conflicting with our definition of fpos_t and with the intent that it be an opaque type. it was accepted for inclusion because, despite not being widely used, it is usually very difficult to extricate software using it from the dependency on it. calling pattern for the read and write callbacks is not likely to match glibc or other implementations, but should work with any reasonable callbacks. in particular the read function is never called without at least one byte being needed to satisfy its caller, so that spurious blocking is not introduced. contracts for what callbacks called from inside libc/stdio can do are always complicated, and at some point still need to be specified explicitly. at the very least, the callbacks must return or block indefinitely (they cannot perform nonlocal exits) and they should not make calls to stdio using their own FILE as an argument.
2017-11-05add new tcp.h socket options from linux v4.13Szabolcs Nagy-2/+7
TCP_ULP is new in linux commit 734942cc4ea6478eed125af258da1bdbb4afe578 TCP_MD5SIG_EXT is new in 8917a777be3ba566377be05117f71b93a5fd909d
2017-11-05add new fcntl.h macros from linux v4.13Szabolcs Nagy-0/+12
for getting/setting write lifetime hints fcntl commands were added in linux commit c75b1d9421f80f4143e389d2d50ddfc8a28c8c35 added under _GNU_SOURCE || _BSD_SOURCE, since RWH_* life time hints are not in the POSIX reserved namespace.

new in linux commit 69ae543969abeba48e04dd93277684c8c0895f3b
2017-11-05add TFD_TIMER_CANCEL_ON_SET that timerfd.h was missingSzabolcs Nagy-0/+1
linux commit 575b1967e10a1f3038266244d2c7a3ca6b99fed8 moved timerfd apis to a new uapi header which showed musl was missing this flag.
2017-11-05add ETH_MIN_MTU and ETH_MAX_MTU from linux v4.10Szabolcs Nagy-0/+2
min max mtu size definitions mostly for drivers. new in linux commits a52ad514fdf3b8a57ca4322c92d2d8d5c6182485 and d894be57ca92c8a8819ab544d550809e8731137b

2017-09-28fix use of memset without declaration in sched.h cpu set macrosRich Felker-0/+1
patch by Jörg Krause.
2017-08-29move IPPORT_RESERVED from netdb.h to netinet/in.hRich Felker-2/+2
it's in the reserved namespace for the latter, where it seems it was historically defined, and some programs expect to find it there.
2017-07-31add _NL_LOCALE_NAME extension to nl_langinfoRich Felker-0/+6
since setlocale(cat, NULL) is required to return the setting for the global locale, there is no standard mechanism to obtain the name of the currently active thread-local locale set by uselocale. this makes it impossible for application/library software to load appropriate translations, etc. unless using the gettext implementation provided by libc, which has privileged access to libc internals. to fill this gap, glibc introduced the _NL_LOCALE_NAME macro which can be used with nl_langinfo to obtain the name. GNU gettext/gnulib code already use this functionality on glibc, and can easily be adapted to make use of it on non-glibc systems if it's available; for other systems they poke at locale implementation internals, which we want to avoid. this patch provides a compatible interface to the one glibc introduced.
2017-07-04remove useless declarations in string.hAlexander Monakov-2/+0
The two functions str{,n}casecmp_l are specified to be declared in <strings.h> which is already included from <string.h> under _GNU_SOURCE.
2017-04-22add no-op POSIX_SPAWN_USEVFORK to spawn.hRich Felker-0/+1
the bit is reserved anyway for ABI-compat reasons; this documents it and makes it so we can have posix_spawnattr_setflags check for flag validity without hard-coding an anonymous bit value.
2017-04-22implement new posix_spawn flag POSIX_SPAWN_SETSIDRich Felker-0/+1
this functionality has been adopted for inclusion in the next issue of POSIX as the result of Austin Group issue #1044. based on patch by Daurnimator.
2016-12-29update tcp_info struct to linux v4.9Szabolcs Nagy-0/+2
export tcp data delivery rate in tcp_info struct. see linux commit eb8329e0a04db0061f714f033b4454326ba147f4
2016-12-29add MS_NOREMOTELOCK mount flag from linux v4.9Szabolcs Nagy-0/+1
for handling file locking on overlayfs. see linux commit c568d68341be7030f5647def68851e469b21ca11
2016-12-16in public headers, don't assume pre-C99 compilers have __inline keywordQuentin Rameau-0/+2
2016-12-15remove legacy i386 fallback stdarg implementation and frameworkRich Felker-4/+0
this has been slated for removal for a long time. there is fundamentally no way to implement stdarg without compiler assistance; any attempt to do so has serious undefined behavior; its working depends not just (as a common misconception goes) on ABI, but also on assumptions about compiler code generation internal to a translation unit, which is not subject to external ABI constraints.
2016-11-11generalize ELF hash table types not to assume 32-bit entriesRich Felker-2/+1
alpha and s390x gratuitously use 64-bit entries (wasting 2x space and cache utilization) despite the values always being 32-bit. based on patch by Bobby Bingham, with changes suggested by Alexander Monakov to use the public Elf_Symndx type from link.h (and make it properly variable by arch) rather than adding new internal infrastructure for handling the type.
2016-11-08add limited pthread_setattr_default_np API to set stack size defaultsRich Felker-0/+2
based on patch by Timo Teräs: While generally this is a bad API, it is the only existing API to affect c++ (std::thread) and c11 (thrd_create) thread stack size. This patch allows applications only to increate stack and guard page sizes.
2016-11-07make netinet/in.h suppress clashing definitions from kernel headersRich Felker-0/+15
the linux kernel uapi headers provide their own definitions of the structures from netinet/in.h, resulting in errors when a program includes both the standard libc header and one or more of the networking-related kernel headers that pull in the kernel definitions. as before, we do not attempt to support the case where kernel headers are included before the libc ones, since the kernel definitions may have subtly incorrect types, namespace violations, etc. however, we can easily support the inclusion of the kernel headers after the libc ones, since the kernel headers provide a public interface for suppressing their definitions. this patch adds the necessary macro definitions for such suppression.
2016-11-07don't claim support for resolv.h APIs that aren't supportedRich Felker-1/+1
the value 19991006 for __RES implies availability of res_ninit and related functions that take a resolver state argument; these are not supported since our resolver is stateless. instead claim support for just the older API by defining __RES to 19960801. based on patch by Dmitrij D. Czarkoff.
2016-11-07remove redundant feature test macro checks in sys/time.hRich Felker-5/+0
this header is XSI-shaded itself and thus does not need to limit specific content to _XOPEN_SOURCE.
2016-10-20fix various header namespace issues under feature-test-macro controlRich Felker-7/+18
reported and changes suggested by Daniel Sabogal.
2016-10-20remove parameter names from public headersRich Felker-9/+9
inclusion of these names was unintentional and in most cases is a namespace violation. Daniel Sabogal tracked down and reported these.
2016-10-20fix misspelling of a legacy macro name in sys/param.hRich Felker-1/+1
2016-10-20add missing if_ether.h constantsDaniel Sabogal-0/+3
ETH_P_HSR (IEC 62439-3 HSRv1) added in linux 4.7 commit ee1c27977284907d40f7f72c2d078d709f15811f ETH_P_TSN (IEEE 1722) added in linux 4.3 commit 1ab1e895492d8084dfc1c854efacde219e56b8c1 this constant breaks the ascending order to match the kernel header ETH_P_XDSA (Multiplexed DSA protocol) added in linux 3.18 commit 3e8a72d1dae374cf6fc1dba97cec663585845ff9
2016-10-20add missing if_arp.h constantDaniel Sabogal-0/+1
ARPHRD_6LOWPAN (IPv6 over LoWPAN) added in linux 3.14 commit 0abc652c796dab74d34d60473ec5594cd21620be
2016-10-20fix typo in utmpx.hDaniel Sabogal-1/+1
2016-10-20add missing confstr constantsDaniel Sabogal-0/+2
the _CS_V6_ENV and _CS_V7_ENV constants are required to be available for use with confstr. glibc defines these constants with values 1148 and 1149, respectively. the only missing (and required) confstr constants are _CS_POSIX_V7_THREADS_CFLAGS and _CS_POSIX_V7_THREADS_LDFLAGS which remain unavailable in glibc.
2016-10-20add pthread_setname_npFelix Janda-0/+1
the thread name is displayed by gdb's "info threads".
