Make the FreeBSD and Linux compat code convert the parameters to their
native representation and call the native routines.
Remove KAUTH_PROCESS_SCHEDULER_GET/SET.
Update documentation and examples.
XXX: For now, only the Linux compat code does the priority conversion
XXX: right.
Linux priority conversion code from yamt@, thanks!
Okay yamt@.
words, don't pass an action and a request, and just use a single action to
indicate what is the operation in question.
This is the first step in fixing PR/37986, which calls for policy/priority
checking in the secmodel code. Right now we're lacking room for another
parameter required to make a decision, and this change makes room for such.
A rather excessive amount of 'appending 64' to names seems to have happened
when linux won support for files > 4G.
technically the linux32_sys_fcntl() function should error the 64bit file
locking requests - but life is too short.
The 64bit linux emulation versions can't be used because the lock structure
alignment and field sizes all differ.
Since there need to be 4 different versions of the linux struct flock, and
amd64 kernel needs 3 of them compiled in, rather than replicating the same
code block twice more, move the body of the code into a few #defines
that can be expanded with the correct types in the linux[32]_sys_fcntl[64]()
functions.
Should fix problems running progams like skype running under linux32
emulation on amd64.
Unravel some of the knots that caused linux_file64.c to be compiled twice
for an amd64 kernel (once for linux and once for linux32) with different
parts being skipped each time.
correct alignment/padding rules.
Removed the now-unnecessary #pragma packed for amd64.
Should fix the alignment of 'struct netbsd32_kevent' on non-amd64.
- Do reference counting for 'struct mount'. Each vnode associated with a
mount takes a reference, and in turn the mount takes a reference to the
vfsops.
- Now that mounts are reference counted, replace the overcomplicated mount
locking inherited from 4.4BSD with a recursable rwlock.
- SHM_STAT take an index as input, and return the corresponding shmid.
- IPC_INFO and SHM_INFO returns the highest used index.
- SHM_INFO expected the total used pages (not bytes) in shm_tot field
of struct shm_info.
in a manner that is endianness independant.
Should mean the amd64 will return correct offsets > 2^32 (sparc64 had a
special define).
Any new netbsd32 ports should work regardless of the endianness.
an 'ssize_t' or 'long' variable to 'register_t'.
If the sizes were different it would either overwrite stack or return
uninitialised stack. On big-endian systems things would be worse!
- Add a KAUTH_PROCESS_SCHEDULER action, to handle scheduler related
requests, and add specific requests for set/get scheduler policy and
set/get scheduler parameters.
- Add a KAUTH_PROCESS_KEVENT_FILTER action, to handle kevent(2) related
requests.
- Add a KAUTH_DEVICE_TTY_STI action to handle requests to TIOCSTI.
- Add requests for the KAUTH_PROCESS_CANSEE action, indicating what
process information is being looked at (entry itself, args, env,
open files).
- Add requests for the KAUTH_PROCESS_RLIMIT action indicating set/get.
- Add requests for the KAUTH_PROCESS_CORENAME action indicating set/get.
- Make bsd44 secmodel code handle the newly added rqeuests appropriately.
All of the above make it possible to issue finer-grained kauth(9) calls in
many places, removing some KAUTH_GENERIC_ISSUSER requests.
- Remove the "CAN" from KAUTH_PROCESS_CAN{KTRACE,PROCFS,PTRACE,SIGNAL}.
Discussed with christos@ and yamt@.
