| 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. |
| |

| 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. |
| |

| 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 |
| |
| |
| |
| 0.7.6 - major 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 |
| |
| fixed bug in POSIX timers created with NULL sigevent argument |

| 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. |
