| 1 0.5.0 - initial release |
| 2 |
| 3 |
| 4 |
| 5 0.5.9 - signal ABI bugfix, various cleanup and fixes: |
| 6 |
| 7 sigset_t was wrongly defined as 1024 bytes instead of 1024 bits, |
| 8 breaking the intended ABI compatibility with the LSB/glibc sigaction |
| 9 structure. users should upgrade immediately and rebuild any libraries |
| 10 or object files that might be using the incorrect definitions. |
| 11 |
| 12 improved security against DoS with tcb shadow passwords by checking |
| 13 that the file opened was really an ordinary file. |
| 14 |
| 15 fixed a bug in the implementation of atomic ops that could have |
| 16 allowed the compiler to incorrectly reorder them (in practice, gcc |
| 17 with the default settings on i386 was not reordering them). |
| 18 |
| 19 greatly improved conformance to the C and POSIX standards regarding |
| 20 what the standard header files make visible. _POSIX_C_SOURCE is now |
| 21 needed to get POSIX functions in standard C headers, and _XOPEN_SOURCE |
| 22 or _GNU_SOURCE are required to get XSI interfaces or GNU extensions, |
| 23 respectively. |
| 24 |
| 25 many internal improvements have been made to the syscall-related code |
| 26 in preparation for porting to x86_64 and other archs. |
| 27 |
| 28 |
| 29 |
| 30 0.6.0 - x86_64 port, various important bugs fixed |
| 31 |
| 32 new x86_64 (amd64) architecture port, contributed by Nicholas J. Kain, |
| 33 along with PORTING guide. source tree layout and build system have |
| 34 been improved to accommodate further ports. |
| 35 |
| 36 various bugs that were introduced while making the headers respect C |
| 37 and POSIX namespace standards have been fixed. conformance to the |
| 38 standards has been improved. |
| 39 |
| 40 fixed an inefficiency in qsort that triggered a bug (occasionaly |
| 41 internal compiler error) in some versions of gcc. |
| 42 |
| 43 fixed a major bug in the printf %n specifier that prevented it from |
| 44 working and caused memory corruption. |
| 45 |
| 46 |
| 47 |
| 48 0.7.0 - major improvements to posix conformance and completeness |
| 49 |
| 50 implemented posix shared memory and semaphore interfaces. |
| 51 |
| 52 implemented all remaining required pthread and clock interfaces. |
| 53 |
| 54 major fixes to signal semantics. |
| 55 |
| 56 greatly improved temporary file name generation for safety against |
| 57 denial of service due to intentional name collisions. |
| 58 |
| 59 added syscall wrappers for the linux inotify interface. |
| 60 |
| 61 malloc(0) now returns a non-null pointer. |
| 62 |
| 63 fixed printf %n specifier (again), pthread_once (it was always |
| 64 hanging), and non-default-type mutex behavior. |
| 65 |
| 66 added ucontext/sigcontext support in headers to facilitate building |
| 67 libgcc with dwarf2 unwind support, and possibly other low-level tools. |
| 68 |
| 69 improved musl-gcc compiler wrapper. |
| 70 |
| 71 implemented many small missing functions here and there, minor header |
| 72 fixes, etc. |
| 73 |
| 74 |
| 75 |
| 76 0.7.1 - improvements to completeness, bug fixes |
| 77 |
| 78 implemented flockfile, wprintf, and robust mutex functions. |
| 79 |
| 80 fixed stack corruption bug in times(), minor header bugs, and some |
| 81 error return value bugs in thread interfaces. |
| 82 |
| 83 |
| 84 |
| 85 0.7.5 - new features, major optimization, and robustness |
| 86 |
| 87 implemented POSIX timers. |
| 88 |
| 89 optimized and simplified many thread-related functions. |
| 90 |
| 91 eliminated resource leak races in thread cancellation. (almost all |
| 92 existing implementations, including glibc, have these leaks.) |
| 93 |
| 94 overhauled stdio implementation to take advantage of readv/writev for |
| 95 reduced syscall load, and improved stdio's handling of error status. |
| 96 |
| 97 added syscall header and interface for applications to use and |
| 98 greatly simplified internal system for making syscalls. |
| 99 |
| 100 strangthened tmpnam/tempnam/tmpfile filename generation and made the |
| 101 straight C functions not depend on POSIX symbols. |
| 102 |
| 103 fixed pthread cancellation ABI on i386 to match the LSB/glibc ABI |
| 104 |
| 105 better double-free handling in malloc |

| 120 |
| 121 fixed race condition in set*id() functions with threads (possible |
| 122 deadlock). further audit still needed though. |
| 123 |
| 124 fseek no longer sets the stream error flag on failed seeks (this was |
| 125 wrong and broke some programs, notably GNU m4). |
| 126 |
| 127 nl_langinfo is no longer a dummy function. (the functionality was |
| 128 previously implemented but accidentally left unused). |
| 129 |
| 130 various small fixes have been made to the implementations and |
| 131 prototypes for nonstandard and obsolete functions |
| 132 |
| 133 |
| 134 |
| 135 0.7.7 - more bug fixes and program-compatibility improvements |
| 136 |
| 137 fixed floating point formatting and rounding bugs in printf. |
| 138 |
| 139 fixed broken %N$ positional argument specifiers in printf. |
| 140 |
| 141 fixed misaligned read/overread bug in strchr which could lead to |
| 142 crashes scanning tiny strings at the end of a page when the next page |
| 143 is not readable, or on archs (not yet supported) that forbid |
| 144 misaligned reads. |
| 145 |
| 146 fixed breakage of statvfs on x86_64 |
| 147 |
| 148 fixed crash in getmntent_r |

| 152 improved semaphore performance, and sem_wait is now interruptable by |
| 153 signals, as required by POSIX. |
| 154 |
| 155 added many compatibility and system-level interfaces, increasing the |
| 156 proportion of busybox that works with musl. |
| 157 |
| 158 |
| 159 |
| 160 0.7.8 - more bug fixes and compatibility improvements |
| 161 |
| 162 fixed problems with ipv6 dns and address printing code that made ipv6 |
| 163 support practically unusable, and some other getaddrinfo bugs. |
| 164 |
| 165 fixed broken sendmsg/recvmsg functions on x86_64 (caused by incorrect |
| 166 msghdr structure). |
| 167 |
| 168 fixed broken sigsetjmp asm on x86_64. |
| 169 |
| 170 worked around a problem with input buffering on terminals reblocking |
| 171 after getting a blank line, due to a bug in the linux readv syscall. |
| 172 |
| 173 various improvements to the "rsyscall" system used to implement |
| 174 threaded setuid, setgid, etc. |
| 175 |
| 176 exiting/cancelling the a timer handler thread no longer kills the |
| 177 timer. |
| 178 |
| 179 fixed incorrect trailing zeros on some %g conversions in printf. |
| 180 |
| 181 fixed buggy byte-swapping functions and moved them to inlines in |
| 182 byteswap.h. |
| 183 |
| 184 many small improvements to header/application compatibility, support |
| 185 for nonstandard macros, etc. |
| 186 |
