similar to: [PATCH 0/5] resubmitting pending patches

While the userspace function signature is int sigsuspend(const sigset_t *maskptr) there are several variants of how this is mapped into kernel functions: one for rt_sigsuspend and several, mutually incompatible, legacy ones, split by architectures. Before this commit, klibc did not care about that and passed maskptr as first and only argument to the syscall, leading to junk in other argument

Here's an assortment of build and run-time fixes for various architectures that we've applied in Debian. Ben. Aurelien Jarno (1): ppc64: fix struct stat Ben Hutchings (2): MIPS: Update archfcntl.h syscalls: Override detection of direct socket syscalls on i386, m68k, s390 Helge Deller (1): Add pread and pwrite 32bit syscall wrappers for parisc Mauricio Faria de Oliveira

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code. This is also available as a git tree at:

Hello, Here is V2 of the arm64 support for klibc patch set. Notable changes since the original series: * fp regs dropped from setjmp/longjmp * chmod, lstat and stat re-implemented with *at functions. * open64 merged into open. As with the original, this series is to be applied against the latest klibc, just after 25a66fa README.klibc: update build information V2 has been tested on x86_64

Hello, This series introduces arm64 support to klibc. I've rebased the work from Neil Williams and Anil Singhar into the following three patches. Most of the code changes are due to new syscall implementations being needed for arm64 as a only a minimal set of syscalls are defined in the arm64 kernel. This series is to be applied against the latest klibc, just after 25a66fa README.klibc:

Use klibc way to define a system dependent preprocessor definition: disabled by default and enabled for newer arm. Based on a patch by vorlon that got tested on his beagleboard, should be functional equivalent.

Hi, after a year, I decided to hack on klibc again. I?ve reworked both the patch to add mkstemp(), discussing to use AT_RANDOM as cheap entropy source on IRC (if there will ever be another entropy consumer, I can quickly write a minimal arc4random() seeded from it, as it has only 16 octets), capable of making a working mksh (static and shared) on amd64/xen, and the m68k support code, leading to

Hi, is there a DD-accessible porterbox somewhere (slow would be ok, as this is smallish software) with an up-to-date sid (enough to install the recently-built libklibc-dev 2.0~rc5-1 and all other B-D of mksh 40.9.20120518-1, as well as strace and gdb-minimal)? Similarily to http://www.zytor.com/pipermail/klibc/2012-May/003229.html I found klibc-compiled programmes on Alpha to fail (SIGSEGV

Hi, number three, where I first thought it was a GCC bug but is apparently bad code in klibc.
