hello karel, thanks a lot for the klibc portability merges. current HEAD klibc failure: mkswap.c: In function ?init_signature_page?: mkswap.c:148: error: ?_SC_PAGESIZE? undeclared (first use in this function) although POSIX encourages sysconf() could util-linux use getpagesize() ? -- maks

...slow, check it out with Solaris truss. Use sockets with large I/O or shared memory on the same system. To see the difference try timex dd if=xyz of=lll bs=5k vs timex dd if=xyz of=lll bs=1024k 3. When allocating memory which will be accessed all the time use valloc() which is memalign(sysconf(_SC_PAGESIZE),size) It aligns memory to the page, so memory copies are word/page align and therefore faster, ie. 4 bytes are copied at once instead of a byte at once. 4. If you use GigaBit ethernet to get performance you need to read/write 64Kbytes to the socket and let the OS break it up into MTU sized packe...

Hi, We are trying to get OpenSSH-1.2.2 stable release to compile under Solaris 2.3 Sparc. It worked perfect for Solaris 2.5, Solaris 2.5.1, Solaris 7 (All on Sparc) and Linux 2.2.13 Intel x86 OpenSSL installs fine without problem, zlib is installed fine without problems and egd.pl installs fine without problems. These are all the current releases, I can get the version numbers if you need

Having something like this available in tree would definitely be useful. For simplicity, why don't we start with support for the second style? This is the long term useful one and would be a good starting point for getting the code in tree. Can you give a pointer to the patch so that I can assess the rough complexity? If it's simple enough, I'd be happy to help get it reviewed

Updated set of patches for coverage. Changes: - change copyright lines - use gcov: instead of cover: in commit comment - use #ifdef in xen/common/sysctl.c instead of dummy inline function - added base documentation in docs/misc - added -h option to xencov
