Enhance the Linux emulation layer to make MegaRAID SAS managements tool happy.

2006-05-05T16:10:45Z

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

Remove kern.elf32.can_exec_dyn sysctl. Instead extend Brandinfo structure

2005-12-26T21:23:57Z

with flags bitfield and set BI_CAN_EXEC_DYN flag for all brands that usually allow executing elf dynamic binaries (aka shared libraries). When it is requested to execute ET_DYN elf image check if this flag is on after we know the elf brand allowing execution if so. PR: kern/87615 Submitted by: Marcin Koziej

Remove linux_mib_destroy() (which I actually added in between 5.0 and 5.1)

2005-12-15T16:30:41Z

which existed to cleanup the linux_osname mutex. Now that MTX_SYSINIT() has grown a SYSUNINIT to destroy mutexes on unload, the extra destroy here was redundant and resulted in panics in debug kernels. MFC after: 1 week Reported by: Goran Gajic ggajic at afrodita dot rcub dot bg dot ac dot yu

1. Change prototype of trapsignal and sendsig to use ksiginfo_t *, most

2005-10-14T12:43:47Z

changes in MD code are trivial, before this change, trapsignal and sendsig use discrete parameters, now they uses member fields of ksiginfo_t structure. For sendsig, this change allows us to pass POSIX realtime signal value to user code. 2. Remove cpu_thread_siginfo, it is no longer needed because we now always generate ksiginfo_t data and feed it to libpthread. 3. Add p_sigqueue to proc structure to hold shared signals which were blocked by all threads in the proc. 4. Add td_sigqueue to thread structure to hold all signals delivered to thread. 5. i386 and amd64 now return POSIX standard si_code, other arches will be fixed. 6. In this sigqueue implementation, pending signal set is kept as before, an extra siginfo list holds additional siginfo_t data for signals. kernel code uses psignal() still behavior as before, it won't be failed even under memory pressure, only exception is when deleting a signal, we should call sigqueue_delete to remove signal from sigqueue but not SIGDELSET. Current there is no kernel code will deliver a signal with additional data, so kernel should be as stable as before, a ksiginfo can carry more information, for example, allow signal to be delivered but throw away siginfo data if memory is not enough. SIGKILL and SIGSTOP have fast path in sigqueue_add, because they can not be caught or masked. The sigqueue() syscall allows user code to queue a signal to target process, if resource is unavailable, EAGAIN will be returned as specification said. Just before thread exits, signal queue memory will be freed by sigqueue_flush. Current, all signals are allowed to be queued, not only realtime signals.

Move MODULE_DEPEND() statements for SYSVIPC dependencies to linux_ipc.c

2005-07-29T19:40:39Z

so that they aren't duplicated 3 times and are also in the same file as the code that depends on the SYSVIPC modules.

o Split out kernel part of execve(2) syscall into two parts: one that

2005-01-29T23:12:00Z

copies arguments into the kernel space and one that operates completely in the kernel space; o use kernel-only version of execve(2) to kill another stackgap in linuxlator/i386. Obtained from: DragonFlyBSD (partially) MFC after: 2 weeks

Do a pass over all modules in the kernel and make them return EOPNOTSUPP

2004-07-15T08:26:07Z

for unknown events. A number of modules return EINVAL in this instance, and I have left those alone for now and instead taught MOD_QUIESCE to accept this as "didn't do anything".

Add an additional field to the elf brandinfo structure to support

2003-12-23T02:42:39Z

quicker exec-time replacement of the elf interpreter on an emulation environment where an entire /compat/* tree isn't really warranted.
