2013-09-01add workaround header for wait.h remapping to sys/wait.hRich Felker1-0/+2
2013-08-30only expose struct tcphdr under _GNU_SOURCERich Felker1-1/+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 Felker1-0/+33
2013-08-28stdbool.h should define __bool_true_false_are_defined even for C++Rich Felker1-2/+2
while the incorporation of this requirement from C99 into C++11 was likely an accident, some software expects it to be defined, and it doesn't hurt. if the requirement is removed, then presumably __bool_true_false_are_defined would just be in the implementation namespace and thus defining it would still be legal.
2013-08-21add SUN_LEN macro to sys/un.h under appropriate feature testsRich Felker1-0/+19
this is ugly and useless, but it seems to be the least-ugly way to provide it...
2013-08-14de-duplicate dn_expand, fix return value and signature, clean upRich Felker1-1/+1
the duplicate code in dn_expand and its incorrect return values are both results of the history of the code: the version in __dns.c was originally written with no awareness of the legacy resolver API, and was later copy-and-paste duplicated to provide the legacy API. this commit is the first of a series that will restructure the internal dns code to share as much code as possible with the legacy resolver API functions. I have also removed the loop detection logic, since the output buffer length limit naturally prevents loops. in order to avoid long runtime when encountering a loop if the caller provided a ridiculously long buffer, the caller-provided length is clamped at the maximum dns name length.
2013-08-14add missing MSG_EXCEPT in sys/msg.hRich Felker1-0/+1
2013-08-13provide declarations for strtod_l and familyRich Felker1-0/+4
these aliases were originally intended to be for ABI compatibility only, but their presence caused regressions in broken gnulib-based software whose configure scripts detect the existing of these functions then use them without declarations, resulting in bogus return values.
2013-08-10fix definitions of WIFSTOPPED and WIFSIGNALED to support up to signal 127Rich Felker2-4/+4
mips has signal numbers up to 127 (formerly, up to 128, but the last one never worked right and caused kernel panic when used), so 127 in the "signal number" field of the wait status is insufficient for determining that the process was stopped. in addition, a nonzero value in the upper bits must be present, indicating the signal number which caused the process to be stopped. details on this issue can be seen in the email with message id CAAG0J9-d4BfEhbQovFqUAJ3QoOuXScrpsY1y95PrEPxA5DWedQ@mail.gmail.com on the linux-mips mailing list, archived at: http://www.linux-mips.org/archives/linux-mips/2013-06/msg00552.html and in the associated thread about fixing the mips kernel bug. commit 4a96b948687166da26a6c327e6c6733ad2336c5c fixed the corresponding issue in uClibc, but introduced a multiple-evaluation issue for the WIFSTOPPED macro. for the most part, none of these issues affected pure musl systems, since musl has up until now (incorrectly) defined SIGRTMAX as 64 on all archs, even mips. however, interpreting status of non-musl programs on mips may have caused problems. with this change, the full range of signal numbers can be made available on mips.
2013-08-10add pthread_setaffinity_np and pthread_getaffinity_np functionsRich Felker1-0/+3
2013-08-10add cpu affinity interfacesRich Felker1-0/+61
this first commit just includes the CPU_* and sched_* interfaces, not the pthread_* interfaces, which may be added later. simple sanity-check testing has been done for the basic interfaces, but most of the macros have not yet been tested.
2013-08-08sys/personality.h: add missing C++ compatrofl0r1-0/+7
2013-08-08sys/personality.h: add missing macrosrofl0r1-0/+33
2013-08-03add some new linux AT_* flagsRich Felker1-0/+2
2013-08-03add prototypes for euidaccess/eaccessRich Felker1-0/+2
2013-08-02fix feature test macro logic for _BSD_SOURCERich Felker3-7/+7
in several places, _BSD_SOURCE was not even implying POSIX, resulting in it being subtractive rather than additive (compared to the default features).
2013-08-02add missing c++ extern "C" wrapping to link.hRich Felker1-0/+8
2013-08-02provide useless 64-bit fcntl macros with _LARGEFILE64_SOURCERich Felker1-0/+3
this is all useless but part of the API, which is part of the _GNU_SOURCE API, so something may need them.
2013-07-30add macros for new(ish) prctl commandsRich Felker1-0/+37
2013-07-30fix some prctl macros that were incorrectly copied into this fileRich Felker1-3/+3
2013-07-27add wrapper headers, with warnings, for various incorrect names under sysRich Felker6-0/+11
also add a warning to the existing sys/poll.h. the warning is absent from sys/dir.h because it is actually providing a slightly different API to the program, and thus just replacing the #include directive is not a valid fix to programs using this one.
2013-07-27a few more fixes for unistd/sysconf feature reportingRich Felker1-0/+1
2013-07-26report presence of ADV and MSG options in unistd.h and sysconfRich Felker1-0/+2
2013-07-26report that posix_spawn is supported in unistd.h and sysconfRich Felker1-0/+1
2013-07-24fix incorrect type for new si_call_addr in siginfo_tRich Felker1-3/+3
apparently the original kernel commit's i386 version of siginfo.h defined this field as unsigned int, but the asm-generic file always had void *. unsigned int is obviously not a suitable type for an address, in a non-arch-specific file, and glibc also has void * here, so I think void * is the right type for it. also fix redundant type specifiers.
2013-07-25add protocol families PF_IB and PF_VSOCK to socket.hSzabolcs Nagy1-1/+5
linux commit 8d36eb01da5d371feffa280e501377b5c450f5a5 (2013-05-29) added PF_IB for InfiniBand linux commit d021c344051af91f42c5ba9fdedc176740cbd238 (2013-02-06) added PF_VSOCK for VMware sockets
2013-07-24update siginfo according to linux headersSzabolcs Nagy1-1/+13
linux commit a0727e8ce513fe6890416da960181ceb10fbfae6 (2012-04-12) added siginfo fields for SIGSYS (seccomp uses it) linux commit ad5fa913991e9e0f122b021e882b0d50051fbdbc (2009-09-16) added siginfo field and si_code values for SIGBUS (hwpoison signal)
2013-07-24add PTRACE_PEEKSIGINFO to ptrace.hSzabolcs Nagy1-0/+11
added in linux-v3.10 commit 84c751bd4aebbaae995fe32279d3dba48327bad4 using stdint.h types for the new ptrace_peeksiginfo_args struct

2013-07-24change jmp_buf to share an underlying type and struct tag with sigjmp_bufRich Felker1-7/+6
this is necessary to meet the C++ ABI target. alternatives were considered to avoid the size increase for non-sig jmp_buf objects, but they seemed to have worse properties. moreover, the relative size increase is only extreme on x86[_64]; one way of interpreting this is that, if the size increase from this patch makes jmp_buf use too much memory, then the program was already using too much memory when built for non-x86 archs.
2013-07-22undefine internal-use type macros at the end of alltypes.hRich Felker1-0/+4
this patch is something of a compromise for a compatibility regression discovered after the header refactoring: libtiff uses _Int64 for its own use. this is absolutely wrong, invalid C, and should not be supported, but it's also frustrating for users when code that used to work suddenly breaks. rather than leave the breakage in place or change musl internals to accommodate broken software, I've found a change that makes the problem go away and improves musl. by undefining these macros at the end of alltypes.h, the temptation to use them in other headers is removed. (for example, I almost used _Int64 in sys/types.h to define u_int64_t rather than adding it back to alltypes.h.) by confining use of these macros to alltypes.h, we keep it easy to go back and change the implementation of alltypes later, if needed.
2013-07-22move register_t and u_int64_t (back) to alltypesRich Felker2-2/+7
during the header refactoring, I had moved u_int64_t out of alltypes under the assumption that we could just use long long everywhere. however, it seems some broken applications make inconsistent mixed use of u_int64_t and uint64_t, resulting in build errors when the underlying type differs.
2013-07-22fix regression in size of nlink_t (broken stat struct) on x86_64Rich Felker1-1/+1
rather than moving nlink_t back to the arch-specific file, I've added a macro _Reg defined to the canonical type for register-size values on the arch. this is not the same as _Addr for (not-yet-supported) 32-on-64 pseudo-archs like x32 and mips n32, so a new macro was needed.
2013-07-22make regoff_t and regex_t match C++ ABIRich Felker2-3/+3
for regoff_t, it's impossible to match on 64-bit archs because glibc defined the type in a non-conforming way. however this change makes the type match on 32-bit archs.
2013-07-22make pthread_key_t unsigned to match ABIRich Felker1-1/+1
2013-07-22make pthread attribute types structs, even when they just have one fieldRich Felker1-3/+3
this change is to get the right tags for C++ ABI matching. it should have no other effects.
2013-07-22change wint_t to unsignedRich Felker3-4/+4
aside from the obvious C++ ABI purpose for this change, it also brings musl into alignment with the compiler's idea of the definition of wint_t (use in -Wformat), and makes the situation less awkward on ARM, where wchar_t is unsigned. internal code using wint_t and WEOF was checked against this change, and while a few cases of storing WEOF into wchar_t were found, they all seem to operate properly with the natural conversion from unsigned to signed.
2013-07-22refactor headers, especially alltypes.h, and improve C++ ABI compatRich Felker18-87/+133
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
2013-07-19add UIO_MAXIOV macro in sys/uio.hRich Felker1-0/+2
while there's no POSIX namespace provision for UIO_* in uio.h, this exact macro name is reserved in XBD 2.2.2. apparently some glibc-centric software expects it to exist, so let's provide it.
2013-07-18fix FILENAME_MAX to match PATH_MAXRich Felker1-1/+1
POSIX is not clear on whether it includes the termination, but ISO C requires that it does. the whole concept of this macro is rather useless, but it's better to be correct anyway.
2013-07-06add NFDBITS in sys/select.h with appropriate feature testsRich Felker1-0/+3
the main use for this macro seems to be knowing the correct allocation granularity for dynamic-sized fd_set objects. such usage is non-conforming and results in undefined behavior, but it is widespread in applications.
2013-07-03add legacy sys/ttydefaults.h headerrofl0r1-0/+39
2013-07-03add legacy scsi/scsi_ioctl.h headerrofl0r1-0/+11
2013-07-03paths.h: remove cruftrofl0r1-9/+0
a research in debian codesearch and grepping over the pkgsrc directory tree have shown that these macros are all either unused, or defined by programs in case they need them.
2013-07-01add stubs for additional legacy ether.h functionsRich Felker1-3/+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.
2013-06-29fix shifts possibly larger than type in major() macroRich Felker1-1/+1
in theory this should not be an issue, since major() should only be applied to type dev_t, which is 64-bit. however, it appears some applications are not using dev_t but a smaller integer type (which works on Linux because the kernel's dev_t is really only 32-bit). to avoid the undefined behavior, do it as two shifts.
