Subject: [PATCH] Use generic errstr.go implementation on musl
From b3840bdcc0eee2a4d099a9af52199944ade7acb9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] syscall, runtime: always call XSI strerror_r
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
glibc provides two version of strerror_r() depending on a feature test
macro. The first is the XSI-compliant version which returns an int, the
second is GNU-specific and returns a char pointer.
This does the right thing for either glibc or musl on GNU/Linux.
Similarity, gcc's libgo provides two implementations of Errstr() both of
which use strerror_r(). On Linux, it is assumed that the GNU-specific
strerror_r version is used. However, musl only provides the
XSI-compliant version of strerror_r. This patch enables the generic
Errstr() implementation which also uses the XSI-compliant version of
strerror_r.
Based on patch by Sören Tempel.

Subject: [PATCH] libgo: use _off_t for mmap offset argument
From 5e658f4659c551330ea68f5667e4f951b218f32d Mon Sep 17 00:00:00 2001

Subject: [PATCH] runtime: use _libgo_off_t_type when calling C mmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On glibc-based systems, off_t is a 32-bit type on 32-bit systems and a
64-bit type on 64-bit systems by default. However, on systems using musl
libc off_t is unconditionally a 64-bit type. As such, it is insufficient
to use a uintptr type for the mmap offset parameter.
The last argument to the C mmap function is type off_t, not uintptr.
On some 32-bit systems, off_t is larger than uintptr.
Presently, the (incorrect) mmap declaration causes a libgo run-time
failure on 32-bit musl systems (fatal error: runtime: cannot allocate
memory). This commit fixes this run-time error.
Based on patch by Sören Tempel.

Subject: [PATCH] syscall, runtime: always call XSI strerror_r
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
glibc provides two version of strerror_r() depending on a feature test
macro. The first is the XSI-compliant version which returns an int, the
second is GNU-specific and returns a char pointer.
This does the right thing for either glibc or musl on GNU/Linux.
Similarity, gcc's libgo provides two implementations of Errstr() both of
which use strerror_r(). On Linux, it is assumed that the GNU-specific
strerror_r version is used. However, musl only provides the
XSI-compliant version of strerror_r. This patch enables the generic
Errstr() implementation which also uses the XSI-compliant version of
strerror_r.
Based on patch by Sören Tempel.

Subject: [PATCH] libgo: use _off_t for mmap offset argument
From 5e658f4659c551330ea68f5667e4f951b218f32d Mon Sep 17 00:00:00 2001

Subject: [PATCH] runtime: use _libgo_off_t_type when calling C mmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On glibc-based systems, off_t is a 32-bit type on 32-bit systems and a
64-bit type on 64-bit systems by default. However, on systems using musl
libc off_t is unconditionally a 64-bit type. As such, it is insufficient
to use a uintptr type for the mmap offset parameter.
The last argument to the C mmap function is type off_t, not uintptr.
On some 32-bit systems, off_t is larger than uintptr.
Presently, the (incorrect) mmap declaration causes a libgo run-time
failure on 32-bit musl systems (fatal error: runtime: cannot allocate
memory). This commit fixes this run-time error.
Based on patch by Sören Tempel.

Subject: [PATCH] Use generic errstr.go implementation on musl
From b3840bdcc0eee2a4d099a9af52199944ade7acb9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] syscall, runtime: always call XSI strerror_r
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
glibc provides two version of strerror_r() depending on a feature test
macro. The first is the XSI-compliant version which returns an int, the
second is GNU-specific and returns a char pointer.
This does the right thing for either glibc or musl on GNU/Linux.
Similarity, gcc's libgo provides two implementations of Errstr() both of
which use strerror_r(). On Linux, it is assumed that the GNU-specific
strerror_r version is used. However, musl only provides the
XSI-compliant version of strerror_r. This patch enables the generic
Errstr() implementation which also uses the XSI-compliant version of
strerror_r.
Based on patch by Sören Tempel.

Subject: [PATCH] libgo: use _off_t for mmap offset argument
From 5e658f4659c551330ea68f5667e4f951b218f32d Mon Sep 17 00:00:00 2001

Subject: [PATCH] runtime: use _libgo_off_t_type when calling C mmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On glibc-based systems, off_t is a 32-bit type on 32-bit systems and a
64-bit type on 64-bit systems by default. However, on systems using musl
libc off_t is unconditionally a 64-bit type. As such, it is insufficient
to use a uintptr type for the mmap offset parameter.
The last argument to the C mmap function is type off_t, not uintptr.
On some 32-bit systems, off_t is larger than uintptr.
Presently, the (incorrect) mmap declaration causes a libgo run-time
failure on 32-bit musl systems (fatal error: runtime: cannot allocate
memory). This commit fixes this run-time error.
Based on patch by Sören Tempel.

Subject: [PATCH] Use generic errstr.go implementation on musl
From b3840bdcc0eee2a4d099a9af52199944ade7acb9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] syscall, runtime: always call XSI strerror_r
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
glibc provides two version of strerror_r() depending on a feature test
macro. The first is the XSI-compliant version which returns an int, the
second is GNU-specific and returns a char pointer.
This does the right thing for either glibc or musl on GNU/Linux.
Similarity, gcc's libgo provides two implementations of Errstr() both of
which use strerror_r(). On Linux, it is assumed that the GNU-specific
strerror_r version is used. However, musl only provides the
XSI-compliant version of strerror_r. This patch enables the generic
Errstr() implementation which also uses the XSI-compliant version of
strerror_r.
Based on patch by Sören Tempel.

Subject: [PATCH] libgo: use _off_t for mmap offset argument
From 5e658f4659c551330ea68f5667e4f951b218f32d Mon Sep 17 00:00:00 2001

Subject: [PATCH] runtime: use _libgo_off_t_type when calling C mmap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On glibc-based systems, off_t is a 32-bit type on 32-bit systems and a
64-bit type on 64-bit systems by default. However, on systems using musl
libc off_t is unconditionally a 64-bit type. As such, it is insufficient
to use a uintptr type for the mmap offset parameter.
The last argument to the C mmap function is type off_t, not uintptr.
On some 32-bit systems, off_t is larger than uintptr.
Presently, the (incorrect) mmap declaration causes a libgo run-time
failure on 32-bit musl systems (fatal error: runtime: cannot allocate
memory). This commit fixes this run-time error.
Based on patch by Sören Tempel.
