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
|
2011-02-15 20:52:26 +00:00
|
|
|
|
|
|
|
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
|
2011-02-17 22:57:50 +00:00
|
|
|
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.

|
|
|
|
|
major fixes to signal semantics.

|
|
|
eliminated resource leak races in thread cancellation. (almost all
|
|
|
|
existing implementations, including glibc, have these leaks.)
|
2011-04-02 00:36:01 +00:00
|
|
|
|
|
|
|
overhauled stdio implementation to take advantage of readv/writev for
|
|
|
|
reduced syscall load, and improved stdio's handling of error status.
|
|
|
|
|
|
|
|
added syscall header and interface for applications to use and
|
|
|
|
greatly simplified internal system for making syscalls.

|
|
|
|
wrong and broke some programs, notably GNU m4).

|
|
|
support practically unusable, and some other getaddrinfo bugs.
|

timer.

fixed incorrect trailing zeros on some %g conversions in printf.
