2018-07-20move inclusion of linux headers for kd.h, soundcard.h, vt.h to bitsmidipix3-3/+3
maintainer's note: while musl does not use the linux kernel headers, it does provide these three sys/* headers which do nothing but include the corresponding linux/* headers, since the sys/* versions are the ones documented for application use (and they arguably provide interfaces that are not linux-specific but common to other unices). these headers should probably not be provided by libc (rather by a separate package), but as long as they are, use the bits header framework as an aid to out-of-tree ports of musl for non-linux systems that want to implement them in some other way.
2018-07-20remove inclusion guard hacks for sys/kd.hmidipix1-7/+0
maintainer's note: at some point, probably long before linux separated the uapi headers, it was the case, or at least I believed it was the case, that linux/types.h was unsafe to include from userspace. thus, the inclusion guard macro _LINUX_TYPES_H was defined in sys/kd.h to prevent linux/kd.h from including linux/types.h (which it spuriously includes but does not use). as far as I can tell, whatever problem this was meant to solve does not seem to have been present for a long time, and the hack was not done correctly anyway, so removing it is the right thing to do.
2018-07-17add support for arch-specific ptrace command macrosSzabolcs Nagy1-0/+2
sys/ptrace.h is target specific, use bits/ptrace.h to add target specific macro definitions. these macros are kept in the generic sys/ptrace.h even though some targets don't support them: PTRACE_GETREGS PTRACE_SETREGS PTRACE_GETFPREGS PTRACE_SETFPREGS PTRACE_GETFPXREGS PTRACE_SETFPXREGS so no macro definition got removed in this patch on any target. only s390x has a numerically conflicting macro definition (PTRACE_SINGLEBLOCK). the PT_ aliases follow glibc headers, otherwise the definitions come from linux uapi headers except ones that are skipped in glibc and there is no real kernel support (s390x PTRACE_*_AREA) or need special type definitions (mips PTRACE_*_WATCH_*) or only relevant for linux 2.4 compatibility (PTRACE_OLDSETOPTIONS).
2018-07-17sys/ptrace.h: add missing PTRACE_EVENT_STOPSzabolcs Nagy1-0/+1
new in linux v3.1 commit 3544d72a0e10d0aa1c1bd59ed77a53a59cdc12f7 changed in linux v3.4 commit 5cdf389aee90109e2e3d88085dea4dd5508a3be7 A tracer recieves this event in the waitpid status of a PTRACED_SEIZED process.
2018-07-12add ST_RELATIME to statvfs.hRich Felker1-0/+1

adapted from patch by Matthias Schiffer.
2018-06-20add memfd_create syscall wrapperSzabolcs Nagy1-0/+5
memfd_create was added in linux v3.17 and glibc has api for it.
2018-06-20add mlock2 linux syscall wrapperSzabolcs Nagy1-3/+8
mlock2 syscall was added in linux v4.4 and glibc has api for it. It falls back to mlock in case of flags==0, so that case works even on older kernels. MLOCK_ONFAULT is moved under _GNU_SOURCE following glibc.
2018-06-19add speculation control prctls from linux v4.17Szabolcs Nagy1-0/+9
PR_{SET,GET}_SPECULATION_CTRL controls speculation related vulnerability mitigations, new in commits b617cfc858161140d69cc0b5cc211996b557a1c7 356e4bfff2c5489e016fdb925adbf12a1e3950ee
2018-06-19add {MSG,SEM,SHM}_STAT_ANY from linux v4.17Szabolcs Nagy3-0/+3
introduced to stat ipc objects without permission checks since the info is available in /proc/sysvipc anyway, new in linux commits 23c8cec8cf679b10997a512abb1e86f0cedc42ba a280d6dc77eb6002f269d58cd47c7c7e69b617b6 c21a6970ae727839a2f300cd8dd957de0d0238c3
2018-06-19add MAP_FIXED_NOREPLACE from linux v4.17Szabolcs Nagy1-0/+1
to map at a fixed address without unmapping underlying mappings (fails with EEXIST unlike MAP_FIXED), new in linux commits 4ed28639519c7bad5f518e70b3284c6e0763e650 and a4ff8e8620d3f4f50ac4b41e8067b7d395056843.
2018-06-19sys/ptrace.h: add PTRACE_SECCOMP_GET_METADATA from linux v4.16Szabolcs Nagy1-1/+7
to get seccomp state for checkpoint restore. added in linux commit 26500475ac1b499d8636ff281311d633909f5d20 struct tag follows the glibc api and ptrace_peeksiginfo_args got changed too accordingly.
2018-06-19sys/epoll.h: add EPOLLNVAL from linux v4.16Szabolcs Nagy1-0/+1
added to uapi in commit 65aaf87b3aa2d049c6b9fd85221858a895df3393 used since commit a9a08845e9acbd224e4ee466f5c1275ed50054e8, which renamed POLL* to EPOLL* in the kernel.
2018-02-22add getrandom syscall wrapperHauke Mehrtens1-0/+19
This syscall is available since Linux 3.17 and was also implemented in glibc in version 2.25 using the same interfaces.
2018-02-22sys/prctl.h: add new PR_SVE_* macros from linux v4.15Szabolcs Nagy1-0/+6
PR_SVE_SET_VL and PR_SVE_GET_VL controls are new in linux commit 2d2123bc7c7f843aa9db87720de159a049839862 related PR_SVE_* macros were added in 7582e22038a266444eb87bc07c372592ad647439
2018-02-22add MAP_SYNC and MAP_SHARED_VALIDATE from linux v4.15Szabolcs Nagy1-0/+2
for synchronous page faults, new in linux commit 1c9725974074a047f6080eecc62c50a8e840d050 and b6fb293f2497a9841d94f6b57bd2bb2cd222da43 note that only targets that use asm-generic/mman.h have this new flag defined, so undef it on other targets (mips*, powerpc*).
2018-02-22sys/{mman,shm}.h: add {MAP,SHM}_HUGE_ macros from linux uapiSzabolcs Nagy2-0/+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.
2018-02-22sys/mman.h: add MADV_WIPEONFORK from linux v4.14Szabolcs Nagy1-0/+2
allows zeroing anonymous private pages inherited by a child process. new in linux commit d2cd9ede6e193dd7d88b6d27399e96229a551b19
2018-02-22sys/socket.h: add MSG_ZEROCOPY from linux v4.14Szabolcs Nagy1-0/+2
MSG_ZEROCOPY socket send flag avoids copy in the kernel new in linux commit 52267790ef52d7513879238ca9fac22c1733e0e3 SO_ZEROCOPY socket option enables MSG_ZEROCOPY if availale new in linux commit 76851d1212c11365362525e1e2c0a18c97478e6b
2018-02-22sys/socket.h: add SOL_TLS from linux v4.13Szabolcs Nagy1-0/+1
socket option for kernel TLS support new in linux commit 3c4d7559159bfe1e3b94df3a657b2cda3a34e218
2018-02-22sys/socket.h: add PF_SMC from linux v4.11Szabolcs Nagy1-1/+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)
2018-01-09add additional uapi guards for Linux kernel header filesHauke Mehrtens1-0/+2
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")
2017-11-05add SO_ getsockopt options from linux v4.13Szabolcs Nagy1-0/+2
SCM_TIMESTAMPING_PKTINFO is new in aad9c8c470f2a8321a99eb053630ce0e199558d6 SO_PEERGROUPS is new in 28b5ba2aa0f55d80adb2624564ed2b170c19519e
2017-11-05add new SO_ socket options from linux v4.12Szabolcs Nagy1-0/+3
SO_MEMINFO added in linux commit a2d133b1d465016d0d97560b11f54ba0ace56d3e SO_INCOMING_NAPI_ID added in 6d4339028b350efbf87c61e6d9e113e5373545c9 SO_COOKIE added in 5daab9db7b65df87da26fd8cfa695fb9546a1ddb
2017-11-05add TFD_TIMER_CANCEL_ON_SET that timerfd.h was missingSzabolcs Nagy1-0/+1
linux commit 575b1967e10a1f3038266244d2c7a3ca6b99fed8 moved timerfd apis to a new uapi header which showed musl was missing this flag.
2017-11-05add SCM_TIMESTAMPING_OPT_STATS and related TCP_ enums from linux v4.10Szabolcs Nagy1-0/+1
for tcp timestamp control messages, new in linux commit 1c885808e45601b2b6f68b30ac1d999e10b6f606 and export time measurements via tcp_info, added in linux commit efd90174167530c67a54273fd5d8369c87f9bd32
2016-12-29add MS_NOREMOTELOCK mount flag from linux v4.9Szabolcs Nagy1-0/+1
for handling file locking on overlayfs. see linux commit c568d68341be7030f5647def68851e469b21ca11
2016-11-07remove redundant feature test macro checks in sys/time.hRich Felker1-5/+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 Felker1-2/+5
reported and changes suggested by Daniel Sabogal.
2016-10-20remove parameter names from public headersRich Felker1-2/+2
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 Felker1-1/+1
2016-10-20add bits/hwcap.h and include it in sys/auxv.hSzabolcs Nagy1-0/+1
aarch64, arm, mips, mips64, mipsn32, powerpc, powerpc64 and sh have cpu feature bits defined in linux for AT_HWCAP auxv entry, so expose those in sys/auxv.h it seems the mips hwcaps were never exposed to userspace neither by linux nor by glibc, but that's most likely an oversight.
2016-08-30add PF_QIPCRTR, AF_QIPCRTR from linux v4.7 to sys/socket.hSzabolcs Nagy1-1/+3
macros for qualcom ip router protocol, new in linux commit bdabad3e363d825ddf9679dd431cca0b2c30f881
2016-07-03make brace placement in public header typedef'd structs consistentRich Felker1-2/+1
commit befa5866ee30d09c0c96e88af2eabff5911342ea performed this change for struct definitions that did not also involve typedef, but omitted the latter.
2016-07-03make brace placement in public header struct definitions consistentRich Felker9-32/+16
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.
2016-07-03fix misplaced indention in sys/procfs.hRich Felker1-1/+1
2016-06-29add RUSAGE_THREAD (Linux extension) definition to sys/resource.hRich Felker1-0/+1
2016-06-29fix incorrect definition of RUSAGE_CHILDREN in sys/resource.hRich Felker1-1/+1
the kernel ABI value for RUSAGE_CHILDREN is -1, not 1. the latter is actually interpreted as RUSAGE_THREAD, to obtain values for just the calling thread and not the whole process.
2016-06-09avoid padding gaps in struct sockaddr_storageRich Felker1-1/+1
compilers are free not to copy, or in some cases to clobber, padding bytes in a structure. while it's an aliasing violation, and thus undefined behavior, to copy or manipulate other sockaddr types using sockaddr_storage, it seems likely that traditional code attempts to do so, and the original intent of the sockaddr_storage structure was probably to allow such usage. in the interest of avoiding silent and potentially dangerous breakage, ensure that there are no actual padding bytes in sockaddr_storage by moving and adjusting the size of the __ss_padding member so that it fits exactly. this change also removes a silent assumption that the alignment of long is equal to its size.
2016-06-09update sys/socket.h to linux v4.6Szabolcs Nagy1-1/+19
kernel connection multiplexor macros AF_KCM, PF_KCM, SOL_KCM were added in linux commit ab7ac4eb9832e32a09f4e8042705484d2fb0aad3 MSG_BATCH sendmsg flag for performance optimization was added in linux commit f092276d85b82504e8a07498f4e9e0c51f06745c SOL_* macros are now synced with linux socket.h which is not a uapi header and glibc did not have the macros either, but that has changed http://sourceware.org/ml/libc-alpha/2016-05/msg00322.html
2016-06-09add SO_CNX_ADVICE to sys/socket.h, new in linux v4.6Szabolcs Nagy1-0/+1
new socket option so application can give advice about routing path quality of connected udp sockets, added in linux commit a87cb3e48ee86d29868d3f59cfb9ce1a8fa63314
2016-05-22fix undefined pointer arithmetic in CMSG_NXTHDR macroRich Felker1-3/+3
previously, the only way the stopping condition could be met with correct lengths in the headers invoked undefined behavior, adding sizeof(struct cmsghdr) beyond the end of the cmsg buffer. instead, compute and compare sizes rather than pointers.
2016-03-19add MADV_FREE madvise command from linux v4.5Szabolcs Nagy1-0/+1
allows the os to free the marked pages lazily on memory pressure. expected to increase malloc performance. new in linux commit 854e9ed09dedf0c19ac8640e91bcc74bc3f9e5c9
2016-03-19add EPOLLEXCLUSIVE epoll flag from linux v4.5Szabolcs Nagy1-0/+1
new flag for exclusive wakeup mode when an event source fd is attached to multiple epoll fds but they should not all receive the events. new in linux commit df0108c5da561c66c333bb46bfe3c1fc65905898
2016-03-19add SO_ATTACH_REUSEPORT_[CE]BPF socket options from linux v4.5Szabolcs Nagy1-1/+2
new socket options for setting classic or extended BPF program for sockets in a SO_REUSEPORT group. added in linux commit 538950a1b7527a0a52ccd9337e3fcd304f027f13
2016-03-18deduplicate bits/mman.hSzabolcs Nagy1-0/+59
currently five targets use the same mman.h constants and the rest share most constants too, so move them to sys/mman.h before the bits/mman.h include where the differences can be corrected by redefinition of the macros. this fixes two minor bugs: POSIX_MADV_DONTNEED was wrong on most targets (it should be the same as MADV_DONTNEED), and sh defined the x86-only MAP_32BIT mmap flag.
2016-01-26add new PTRACE_SECCOMP_GET_FILTER ptrace commandSzabolcs Nagy1-0/+1
allows the tracer to dump the bpf seccomp filters of the tracee, new in linux v4.4, commit f8e529ed941ba2bbcbf310b575d968159ce7e895
2016-01-26add MCL_ONFAULT and MLOCK_ONFAULT mlockall and mlock2 flagsSzabolcs Nagy1-0/+1
they lock faulted pages into memory (useful when a small part of a large mapped file needs efficient access), new in linux v4.4, commit b0f205c2a3082dd9081f9a94e50658c5fa906ff1 MLOCK_* is not in the POSIX reserved namespace for sys/mman.h
2016-01-26add new PTRACE_O_SUSPEND_SECCOMP ptrace optionSzabolcs Nagy1-1/+2
allows a ptracer process to disable/enable seccomp filters of the traced process, useful for checkpoint/restore, new in v4.3 commit 13c4a90119d28cfcb6b5bdd820c233b86c2b0237
2016-01-26add new PR_CAP_AMBIENT and related defines to sys/prctl.hSzabolcs Nagy1-0/+6
ambient capability mask is new in linux v4.3, commit 58319057b7847667f0c9585b9de0e8932b0fdb08
