| 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. |
