* Rather than using hidden includes (with cicular dependencies),Bjoern A. Zeeb2008-12-021-1/+1
| | | | | | | | | | | | | | directly include only the header files needed. This reduces the unneeded spamming of various headers into lots of files. For now, this leaves us with very few modules including vnet.h and thus needing to depend on opt_route.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the linux_io_* syscalls (AIO). They are only enabled if the native AIO code is available (either compiled in to the kernel or as a module) at the time the functions are used. If the AIO stuff is not available there will be a ENOSYS. From the submitter: ---snip--- DESIGN NOTES: 1. Linux permits a process to own multiple AIO queues (distinguished by "context"), but FreeBSD creates only one single AIO queue per process. My code maintains a request queue (STAILQ of queue(3)) per "context", and throws all AIO requests of all contexts owned by a process into the single FreeBSD per-process AIO queue. When the process calls io_destroy(2), io_getevents(2), io_submit(2) and io_cancel(2), my code can pick out requests owned by the specified context from the single FreeBSD per-process AIO queue according to the per-context request queues maintained by my code. 2. The request queue maintained by my code stores contrast information between Linux IO control blocks (struct linux_iocb) and FreeBSD IO control blocks (struct aiocb). FreeBSD IO control block actually exists in userland memory space, required by FreeBSD native aio_XXXXXX(2). 3. It is quite troubling that the function io_getevents() of libaio-0.3.105 needs to use Linux-specific "struct aio_ring", which is a partial mirror of context in user space. I would rather take the address of context in kernel as the context ID, but the io_getevents() of libaio forces me to take the address of the "ring" in user space as the context ID. To my surprise, one comment line in the file "io_getevents.c" of libaio-0.3.105 reads: Ben will hate me for this REFERENCE: 1.

* Enhance the Linux emulation layer to make MegaRAID SAS managements tool happy.Doug Ambrisko2006-05-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. MegaCli will not run until I add in the linsysfs and mfi Linux compat changes. Sponsored by: IronPort Systems Notes: svn path=/head/; revision=158311

* Round of cleanups and enhancements. These include (in random order):Marcel Moolenaar2001-09-081-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Introduce private types for use in linux syscalls for two reasons: 1. establish type independence for ease in porting and, 2. provide a visual queue as to which syscalls have proper prototypes to further cleanup the i386/alpha split. Linuxulator types are prefixed by 'l_'. void and char have not been "virtualized". o Provide dummy functions for all syscalls and remove dummy functions or implementations of truely obsolete syscalls. o Sanitize the shm*, sem* and msg* syscalls. o Make a first attempt to implement the linux_sysctl syscall. At this time it only returns one MIB (KERN_VERSION), but most importantly, it tells us when we need to add additional sysctls :-) o Bump the kenel version up to 2.4.2 (this is not the same as the KERN_VERSION MIB, BTW). o Implement new syscalls, of which most are specific to i386. Our syscall table is now up to date with Linux 2.4.2. Some highlights: - Implement the 32-bit uid_t and gid_t bases syscalls. - Implement a couple of 64-bit file size/offset bases syscalls. o Fix or improve numerous syscalls and prototypes. o Reduce style(9) violations while I'm here. Especially indentation inconsistencies within the same file are addressed. Re-indenting did not obfuscate actual changes to the extend that it could not be combined. NOTE: I spend some time testing these changes and found that if there were regressions, they were not caused by these changes AFAICT. It was observed that installing a RH 7.1 runtime environment did make matters worse. Hangs and/or reboots have been observed with and without these changes, so when it failed to make life better in cases it doesn't look like it made it worse. Notes: svn path=/head/; revision=83221

However, /etc/rc and the linux_base port were adjusted a while back to cope with the absence of this script.
