- sync linuxulator: * de-COMPAT_43-ify: + socket related ioctl's This differs from -current, as the kernel ABI is different (kern_bind() and kern_connect() free the struct sockaddr on -stable themself, so two calls to free() are not included in this MFC). * bug-/compatibility-fixes * ioctl TIOCGPTN * 1 style(9)-fix Tested by: "Arno J.

amd64. amd64 has a separate tf_addr in the trapframe unlike i386 which reuses tf_err to pass the address to signals.

MFC: Rework the support used by ABIs to override resource limits so that

2007-05-23T18:24:43Z

a 64-bit process exec'd by a 32-bit process doesn't end up with 32-bit limits. This doesn't break the ABI as neither of the 32-bit ABIs (COMPAT_LINUX32 and COMPAT_IA32) are buildable as modules on 6.x/amd64 and none of the other ABIs use this hook.

MFC the enhancements to the Linux emulation layer so the MegaRAID SAS

2006-06-15T15:52:05Z

management tools can work. This is not totally connected to the build yet. The mfi(4) change have not been MFC'ed yet. This will be done shortly. I'm trying to do this in chunks so I don't totally break the build on a missed commit. This has passed make universe a while ago: Enhance the Linux emulation layer to make MegaRAID SAS managements tool happy. Add back in a scheme to emulate old type major/minor numbers via hooks into stat, linprocfs to return major/minors that Linux app's expect. Currently only /dev/null is always registered. Drivers can register via the Linux type shim similar to the ioctl shim but by using linux_device_register_handler/linux_device_unregister_handler functions. The structure is: struct linux_device_handler { char *bsd_driver_name; char *linux_driver_name; char *bsd_device_name; char *linux_device_name; int linux_major; int linux_minor; int linux_char_device; }; Linprocfs uses this to display the major number of the driver. The soon to be available linsysfs will use it to fill in the driver name. Linux_stat uses it to translate the major/minor into Linux type values. Note major numbers are dynamically assigned via passing in a -1 for the major number so we don't need to keep track of them. This is somewhat needed due to us switching to our devfs.
