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

|
---|
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
|

|
---|
139 | fixed broken %N$ positional argument specifiers in printf.

|
---|
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 |

|
---|
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.
|
---|
