Rich Felker | df6e3ec | 2011-02-14 21:58:53 -0500 | [diff] [blame] | 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. |

Rich Felker | 982a478 | 2011-02-17 19:15:08 -0500 | [diff] [blame] | 30 | 0.6.0 - x86_64 port, various important bugs fixed |
Rich Felker | 62275f7 | 2011-02-15 15:52:26 -0500 | [diff] [blame] | 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 |
Rich Felker | d09d068 | 2011-02-17 17:57:50 -0500 | [diff] [blame] | 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. |

| 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 | |
Rich Felker | 6f05b6b | 2011-03-11 13:38:09 -0500 | [diff] [blame] | 61 | malloc(0) now returns a non-null pointer. |
Rich Felker | 8d07a03 | 2011-03-11 00:48:40 -0500 | [diff] [blame] | 62 | |
Rich Felker | 9f50b77 | 2011-03-11 14:51:36 -0500 | [diff] [blame] | 63 | fixed printf %n specifier (again), pthread_once (it was always |
| 64 | hanging), and non-default-type mutex behavior. |
Rich Felker | 8d07a03 | 2011-03-11 00:48:40 -0500 | [diff] [blame] | 65 | |
| 66 | added ucontext/sigcontext support in headers to facilitate building |
| 67 | libgcc with dwarf2 unwind support, and possibly other low-level tools. |
| 68 | |
Rich Felker | 6f05b6b | 2011-03-11 13:38:09 -0500 | [diff] [blame] | 69 | improved musl-gcc compiler wrapper. |
| 70 | |
Rich Felker | 8d07a03 | 2011-03-11 00:48:40 -0500 | [diff] [blame] | 71 | implemented many small missing functions here and there, minor header |
| 72 | fixes, etc. |

| 90 | |
Rich Felker | d1c24ac | 2011-04-01 23:15:29 -0400 | [diff] [blame] | 91 | eliminated resource leak races in thread cancellation. (almost all |
| 92 | existing implementations, including glibc, have these leaks.) |
Rich Felker | 78eb087 | 2011-04-01 20:36:01 -0400 | [diff] [blame] | 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. |
Rich Felker | c1f1500 | 2011-04-01 20:47:54 -0400 | [diff] [blame] | 102 | |

| 109 | |
| 110 | |
| 111 | 0.7.6 - major bug fixes |
| 112 | |
| 113 | fixed rare but serious under-allocation bug in malloc. |
| 114 | |
| 115 | fixed signedness bug in strchr that prevented finding high bytes. |
| 116 | |
| 117 | fixed serious parsing bugs in strtold. |
| 118 | |
| 119 | fixed statvfs syscall (it was always failing with EINVAL). |
| 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 |
