* beacon handling fixups for adhoc mode:Sam Leffler2005-01-241-12/+21
| | | | | | | | | | | | | o don't reclaim any previous beacon state in ath_beacon_alloc; do it explicitly in ath_newstate o reference count the node held in the beacon frame state block o process ibss merge more intelligently; let the state machine do the right thing instead of explicitly setting the new bssi id o explicitly stop tx dma before doing beacon setup to handle the ibss merge case Notes: svn path=/head/; revision=140759

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB device support): - Convert all of my locally chosen function names to their actual Windows equivalents, where applicable. This is a big no-op change since it doesn't affect functionality, but it helps avoid a bit of confusion (it's now a lot easier to see which functions are emulated Windows API routines and which are just locally defined). - Turn ndis_buffer into an mdl, like it should have been. The structure is the same, but now it belongs to the subr_ntoskrnl module. - Implement a bunch of MDL handling macros from Windows and use them where applicable. - Correct the implementation of IoFreeMdl(). - Properly implement IoAllocateMdl() and MmBuildMdlForNonPagedPool(). - Add the definitions for struct irp and struct driver_object. - Add IMPORT_FUNC() and IMPORT_FUNC_MAP() macros to make formatting the module function tables a little cleaner. (Should also help with AMD64 support later on.) - Fix if_ndis.c to use KeRaiseIrql() and KeLowerIrql() instead of the previous calls to hal_raise_irql() and hal_lower_irql() which have been renamed. The function renaming generated a lot of churn here, but there should be very little operational effect. Notes: svn path=/head/; revision=140751

| | | | | | | | | | | | | | | | | | | | - Remove some KASSERTs which are invalid if the appropriate lock is not held. - Slightly restructure bremfree() so that it is more sane. - Change the flush code in bdwrite() to avoid acquiring a mutex whenever possible. - Change the flush code in bdwrite() to avoid holding the bufobj mutex while calling buf_countdeps(). This introduces a lock-order relationship with the softdep lock that can not otherwise be resolved. - Don't set B_DONE until bufdone() is complete, otherwise another processor may believe the buf is done before it is. - Only acquire Giant if the caller has set b_iodone. Don't grab giant around normal bufdone() calls. Sponsored By: Isilon Systems, Inc. Notes: svn path=/head/; revision=140721

This simplifies some locking. - Remove several GIANT_REQUIRED lines. - Add a few KASSERTs to help with INACT debugging. Sponsored By: Isilon Systems, Inc. Notes: svn path=/head/; revision=140720

| | | | | | | | | | | | | | | | - Protect access to mnt_kern_flag with the mountpoint mutex. - Use the appropriate nd flags to deal with giant in vn_open_cred(). We currently determine whether the caller is mpsafe by checking for a valid fdidx. Any caller coming from user-space is now mpsafe and supplies a valid fd. No kenrel callers have been converted to mpsafe, so this check is sufficient for now. - Use VFS_LOCK_GIANT instead of manual giant acquisition where appropriate. Sponsored By: Isilon Systems, Inc.

Previously, sleeps in getdirtybuf() could leave us with pointers to bad memory. - Update handling of ffs to be compatible with ffs locking changes. Sponsored By: Isilon Systems, Inc.

| | | | | | | | | | | | | | | it is now quite naturally protected by the ufsmount mutex. - Use the ufs lock to protect various fields in struct fs, primarily the cg summary needs protection to avoid allocation races. Several functions have been slightly re-arranged to reduce the number of lock operations. - Adjust several functions (blkfree, freefile, etc.) to accept a ufsmount as an argument so that we may access the ufs lock.

| | | | | | | | | | | | | caller may not be holding Giant, and namei() should acquire it as necessary. HASGIANT is used to indicate when namei() is returning with a reference to a vnode that requires giant, and giant is locked. - Add the macro NDHASGIANT() which can be used in conjunction with VFS_UNLOCK_GIANT() in callers who have marked the nd with MPSAFE. Sponsored By: Isilon Systems, Inc. Notes: svn path=/head/; revision=140698
* - Add the mount flag MNTK_MPSAFE which indicates whether or not GiantJeff Roberson2005-01-241-0/+24
