| * | add missing MSG_EXCEPT in sys/msg.h | Rich Felker | 2013-08-14 | 1 | -0/+1 |
| * | fix definitions of WIFSTOPPED and WIFSIGNALED to support up to signal 127•••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.

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.

| * | add wrapper headers, with warnings, for various incorrect names under sys•••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.

| * | move register_t and u_int64_t (back) to alltypes•••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.
| Rich Felker | 2013-07-22 | 1 | -2/+5 |
| * | refactor headers, especially alltypes.h, and improve C++ ABI compat•••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 UIO_MAXIOV macro in sys/uio.h•••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.
| Rich Felker | 2013-07-19 | 1 | -0/+2 |
| * | add NFDBITS in sys/select.h with appropriate feature tests•••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.
| Rich Felker | 2013-07-06 | 1 | -0/+3 |
| * | add legacy sys/ttydefaults.h header | rofl0r | 2013-07-03 | 1 | -0/+39 |
| * | fix shifts possibly larger than type in major() macro•••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.
| Rich Felker | 2013-06-29 | 1 | -1/+1 |
| * | work around wrong kernel type for sem_nsems member of struct semid_ds•••rejecting invalid values for n is fine even in the case where a new
sem will not be created, since the kernel does its range checks on n
even in this case as well.
by default, the kernel will bound the limit well below USHRT_MAX
anyway, but it's presumably possible that an administrator could
override this limit and break things.
| Rich Felker | 2013-06-28 | 1 | -1/+9 |
| * | add missing type shmatt_t in sys/shm.h•••this type is not really intended to be used; it's just there to allow
implementations to choose the type for the shm_nattch member of
struct shmid_sh, presumably since historical implementations disagreed
on the type. in any case, it needs to be there, so now it is.

| * | fix the prototype of settimeofday to follow the original BSD declaration | Szabolcs Nagy | 2013-05-26 | 1 | -5/+5 |
| * | support full range of dev_t major/minor numbers in makedev, etc. macros | Rich Felker | 2013-05-15 | 1 | -3/+10 |
| * | re-add useconds_t•••this type was removed back in 5243e5f1606a9c6fcf01414e ,
because it was removed from the XSI specs.
however some apps use it.
since it's in the POSIX reserved namespace, we can expose it
unconditionally.

| * | add new socket options to sys/socket.h following linux | Szabolcs Nagy | 2013-04-01 | 1 | -2/+17 |
| * | add ADJ_SETOFFSET timex mode bit (new in linux v2.6.39) | Szabolcs Nagy | 2013-04-01 | 1 | -0/+1 |
| * | fix epoll structure alignment on non-x86_64 archs•••this fix is far from ideal and breaks the rule of not using
arch-specific #ifdefs, but for now we just need a solution to the
existing breakage.
the underlying problem is that the kernel folks made a very stupid
decision to make misalignment of this struct part of the kernel
API/ABI for x86_64, in order to avoid writing a few extra lines of
code to handle both 32- and 64-bit userspace on 64-bit kernels. I had
just added the packed attribute unconditionally thinking it was
harmless on 32-bit archs, but non-x86 32-bit archs have 8-byte
alignment on 64-bit types.

| * | add SWAP_FLAG_DISCARD to sys/swap.h | Szabolcs Nagy | 2013-01-12 | 1 | -0/+1 |
| * | add mount flags to sys/mount.h•••added various MS_*, MNT_*, UMOUNT_* flags following the linux
headers, with one exception: MS_NOUSER is defined as (1U<<31)
instead of (1<<31) which invokes undefined behaviour
the S_* flags were removed following glibc
| Szabolcs Nagy | 2013-01-12 | 1 | -4/+22 |

| Szabolcs Nagy | 2013-01-12 | 1 | -0/+2 |
| * | add missing ptrace requests and options to sys/ptrace.h | Szabolcs Nagy | 2013-01-12 | 1 | -1/+9 |
| * | add missing protocol families to sys/socket.h•••missing protocol families based on current linux headers:
PF_RDS, PF_LLC, PF_CAN, PF_TIPC, PF_NFC
| Szabolcs Nagy | 2013-01-12 | 1 | -1/+11 |
| * | fix another case of cloexec/nonblock flags not matching arch values | Rich Felker | 2013-01-10 | 1 | -2/+3 |
| * | wait.h: add linux specific, thread-related waitpid() flags•••these flags are needed in order to be able to handle lwp id's
which the kernel returns after clone() calls for new threads
via ptrace(PTRACE_GETEVENTMSG).
fortunately, they're the same for all archs and in the reserved
namespace.
| rofl0r | 2013-01-04 | 1 | -0/+4 |
| * | align EPOLL_* flags with fcntl O_* flag definitions, which vary by arch•••the old definitions were wrong on some archs. actually, EPOLL_NONBLOCK
probably should not even be defined; it is not accepted by the kernel
and it's not clear to me whether it has any use at all, even if it did
work. this issue should be revisited at some point, but I'm leaving it
in place for now in case some applications reference it.
| Rich Felker | 2012-12-27 | 1 | -2/+3 |
| * | socket.h: add SO_(SND/RCV)BUFFORCE to generic block | rofl0r | 2012-12-19 | 1 | -0/+2 |
| * | add some missing macros to sys/shm.h•••these are not specified in the standard, but in the reserved
namespace, so there is no problem with defining them unconditionally.
| Rich Felker | 2012-12-15 | 1 | -0/+3 |
| * | add missing flags in sys/timerfd.h | Rich Felker | 2012-12-13 | 1 | -0/+6 |
| * | fix regressions in app compatibility from previous sys/ipc.h changes•••despite glibc using __key and __seq rather than key and seq, some
applications, notably busybox, assume the names are key and seq unless
glibc is being used. and the names key and seq are really the ones
that _should_ be exposed when not attempting to present a
standards-conforming namespace; apps should not be using names that
begin with double-underscore. thus, the optimal fix is to use key and
seq as the actual names of the members when in bsd/gnu source profile,
and define macros for __key and __seq that redirect to plain key and
seq.
| Rich Felker | 2012-12-10 | 1 | -0/+5 |
| * | syscall() declaration belongs in unistd.h, not sys/syscall.h•••traditionally, both BSD and GNU systems have it this way.
sys/syscall.h is purely syscall number macros. presently glibc exposes
the syscall declaration in unistd.h only with _GNU_SOURCE, but that
does not reflect historical practice.
| Rich Felker | 2012-12-10 | 1 | -10/+0 |
| * | fix names of ipc_perm __key/__seq elements•••previously the names were exposed as key/seq with _GNU_SOURCE and
__ipc_perm_key/__ipc_perm/seq otherwise, whereas glibc always uses
__key and __seq for the names. thus, the old behavior never matched
glibc, and the new behavior always does, regardless of feature test
macros.
for now, i'm leaving the renaming here in sys/ipc.h where it's easy to
change globally for all archs, in case something turns out to be
wrong, but eventually the names could just be incorporated directly
into the bits headers for each arch and the renaming removed.

| * | add personality syscall | rofl0r | 2012-12-06 | 1 | -0/+6 |
| * | add struct msgbuf to sys/msg.h | rofl0r | 2012-12-06 | 1 | -0/+7 |
| * | ipc.h: fix gnu aliases for key and seq in struct ipc_perm•••the macro was the wrong way round, additionally GNU defines
__ prefixed versions, which are used by qemu.
| rofl0r | 2012-12-06 | 1 | -2/+4 |
| * | add obsolete futimesat()•••this function is obsolete, however it's available as a syscall
and as such qemu userspace emulation tries to forward it to the
host kernel.
| rofl0r | 2012-12-06 | 1 | -0/+1 |
| * | feature test macros: make _GNU_SOURCE enable everything•••previously, a few BSD features were enabled only by _BSD_SOURCE, not
by _GNU_SOURCE. since _BSD_SOURCE is default in the absence of other
feature test macros, this made adding _GNU_SOURCE to a project not a
purely additive feature test macro; it actually caused some features
to be suppressed.
most of the changes made by this patch actually bring musl in closer
alignment with the glibc behavior for _GNU_SOURCE. the only exceptions
are the added visibility of functions like strlcpy which were BSD-only
due to being disliked/rejected by glibc maintainers. here, I feel the
consistency of having _GNU_SOURCE mean "everything", and especially
the property of it being purely additive, are more valuable than
hiding functions which glibc does not have.
| Rich Felker | 2012-12-03 | 1 | -4/+1 |
| * | fix eventfd and inotify nonblock/cloexec flags to match arch values | Rich Felker | 2012-11-26 | 2 | -4/+6 |
| * | make sys/procfs.h mostly work on most archs•••these structures are purely for use by trace/debug tools and tools
working with core files. the definition of fpregset_t, which was
previously here, has been removed because it was wrong; fpregset_t
should be the type used in mcontext_t, not the type used in
ptrace/core stuff.
| Rich Felker | 2012-11-25 | 1 | -18/+0 |
| * | fix breakage from introducing bits header for sys/io.h•••apparently some other archs have sys/io.h and should not break just
because they don't have the x86 port io functions. provide a blank
bits/io.h everywhere for now.
