0.5.0 - initial release
|
|
|
|
|
|
|
|
0.5.9 - signal ABI bugfix, various cleanup and fixes:
|
|
|
|
sigset_t was wrongly defined as 1024 bytes instead of 1024 bits,
|
|
breaking the intended ABI compatibility with the LSB/glibc sigaction
|
|
structure. users should upgrade immediately and rebuild any libraries
|
|
or object files that might be using the incorrect definitions.
|
|
|
|
improved security against DoS with tcb shadow passwords by checking
|
|
that the file opened was really an ordinary file.
|
|
|
|
fixed a bug in the implementation of atomic ops that could have
|
|
allowed the compiler to incorrectly reorder them (in practice, gcc
|
|
with the default settings on i386 was not reordering them).
|
|
|
|
greatly improved conformance to the C and POSIX standards regarding
|
|
what the standard header files make visible. _POSIX_C_SOURCE is now
|
|
needed to get POSIX functions in standard C headers, and _XOPEN_SOURCE
|
|
or _GNU_SOURCE are required to get XSI interfaces or GNU extensions,
|
|
respectively.
|
|
|
|
many internal improvements have been made to the syscall-related code
|
|
in preparation for porting to x86_64 and other archs.
|
|
|
|
|
|
|
|
0.6.0 - x86_64 port, various important bugs fixed
|
|
|
|
new x86_64 (amd64) architecture port, contributed by Nicholas J. Kain,
|
|
along with PORTING guide. source tree layout and build system have
|
|
been improved to accommodate further ports.
|
|
|
|
various bugs that were introduced while making the headers respect C
|
|
and POSIX namespace standards have been fixed. conformance to the
|
|
standards has been improved.
|
|
|
|
fixed an inefficiency in qsort that triggered a bug (occasionaly
|
|
internal compiler error) in some versions of gcc.
|
|
|
|
fixed a major bug in the printf %n specifier that prevented it from
|
|
working and caused memory corruption.
|
|
|
|
|
|
|
|
0.7.0 - major improvements to posix conformance and completeness
|
|
|
|
implemented posix shared memory and semaphore interfaces.
|
|
|
|
implemented all remaining required pthread and clock interfaces.
|
|
|
|
major fixes to signal semantics.
|
|
|
|
greatly improved temporary file name generation for safety against
|
|
denial of service due to intentional name collisions.
|
|
|
|
added syscall wrappers for the linux inotify interface.
|
|
|
|
malloc(0) now returns a non-null pointer.
|
|
|
|
fixed printf %n specifier (again), pthread_once (it was always
|
|
hanging), and non-default-type mutex behavior.
|
|
|
|
added ucontext/sigcontext support in headers to facilitate building
|
|
libgcc with dwarf2 unwind support, and possibly other low-level tools.
|
|
|
|
improved musl-gcc compiler wrapper.
|
|
|
|
implemented many small missing functions here and there, minor header
|
|
fixes, etc.
|
|
|
|
|
|
|
|
0.7.1 - improvements to completeness, bug fixes
|
|
|
|
implemented flockfile, wprintf, and robust mutex functions.
|
|
|
|
fixed stack corruption bug in times(), minor header bugs, and some
|
|
error return value bugs in thread interfaces.
|
|
|
|
|
|
|
|
0.7.5 - new features, major optimization, and robustness
|
|
|
|
implemented POSIX timers.
|
|
|
|
optimized and simplified many thread-related functions.
|
|
|
|
eliminated resource leak races in thread cancellation. (almost all
|
|
existing implementations, including glibc, have these leaks.)
|
|
|
|
overhauled stdio implementation to take advantage of readv/writev for
|
|
reduced syscall load, and improved stdio's handling of error status.
|
|
|
|
added syscall header and interface for applications to use and
|
|
greatly simplified internal system for making syscalls.
|
|
|
|
strangthened tmpnam/tempnam/tmpfile filename generation and made the
|
|
straight C functions not depend on POSIX symbols.
|
|
|
|
fixed pthread cancellation ABI on i386 to match the LSB/glibc ABI
|
|
|
|
better double-free handling in malloc
|
|
|
|
various minor bug fixes
|
|
|
|
|
|
|
|

|
|
|
fixed rare but serious under-allocation bug in malloc.
|
|
|
|
fixed signedness bug in strchr that prevented finding high bytes.
|
|
|
|
fixed serious parsing bugs in strtold.
|
|
|
|
fixed statvfs syscall (it was always failing with EINVAL).
|
|
|
|
fixed race condition in set*id() functions with threads (possible
|
|
deadlock). further audit still needed though.
|
|
|
|
fseek no longer sets the stream error flag on failed seeks (this was
|
|
wrong and broke some programs, notably GNU m4).
|
|
|
|
nl_langinfo is no longer a dummy function. (the functionality was
|
|
previously implemented but accidentally left unused).
|
|
|
|
various small fixes have been made to the implementations and
|
|
prototypes for nonstandard and obsolete functions
|
|
|
|
|
|
|
|
0.7.7 - more bug fixes and program-compatibility improvements
|
|
|
|
fixed floating point formatting and rounding bugs in printf.
|
|
|
|
fixed broken %N$ positional argument specifiers in printf.
|
|
|
|
fixed misaligned read/overread bug in strchr which could lead to
|
|
crashes scanning tiny strings at the end of a page when the next page
|
|
is not readable, or on archs (not yet supported) that forbid
|
|
misaligned reads.
|
|
|
|
fixed breakage of statvfs on x86_64
|
|
|
|
fixed crash in getmntent_r
|
|
|
|

|
|
|
|
improved semaphore performance, and sem_wait is now interruptable by
|
|
signals, as required by POSIX.
|
|
|
|
added many compatibility and system-level interfaces, increasing the
|
|
proportion of busybox that works with musl.
|
|
|
|
|
|
|
|
0.7.8 - more bug fixes and compatibility improvements
|
|
|
|
fixed problems with ipv6 dns and address printing code that made ipv6
|
|
support practically unusable, and some other getaddrinfo bugs.
|
|
|
|
fixed broken sendmsg/recvmsg functions on x86_64 (caused by incorrect
|
|
msghdr structure).
|
|
|
|
fixed broken sigsetjmp asm on x86_64.
|
|
|
|
worked around a problem with input buffering on terminals reblocking
|
|
after getting a blank line, due to a bug in the linux readv syscall.
|
|
|
|
various improvements to the "rsyscall" system used to implement
|
|
threaded setuid, setgid, etc.
|
|
|
|
exiting/cancelling the a timer handler thread no longer kills the
|
|
timer.
|
|
|
|
fixed incorrect trailing zeros on some %g conversions in printf.
|
|
|
|
fixed buggy byte-swapping functions and moved them to inlines in
|
|
byteswap.h.
|
|
|
|
many small improvements to header/application compatibility, support
|
|
for nonstandard macros, etc.

|
