| 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 |

|---|
| 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.

| 82 |
|
|---|
| 83 |

|
|---|
| 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 |

|
|---|
| 101 | straight C functions not depend on POSIX symbols.

|---|
| 120 |
|
|---|
| 121 | fixed race condition in set*id() functions with threads (possible
|
|---|
| 122 | deadlock). further audit still needed though.
|
|---|
| 123 |

|
|---|
| 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).

|
|---|
| 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.

|
|---|
| 165 | fixed broken sendmsg/recvmsg functions on x86_64 (caused by incorrect
|
|---|
| 166 | msghdr structure).
|
|---|
| 167 |
