Use SMB_QUERY_FS_SIZE_INFO request to populate statfs structure. When server doesn't support this request, try to use SMB_INFO_ALLOCATION. And use SMB_COM_QUERY_INFORMATION_DISK request as fallback. MFC r264600: Remove redundant unlock. This code was removed from the opensolaris and darwin's netsmb implementations, in DfBSD it also has been disabled.

If the kernel is compiled with VMIMAGE support, the first attempt of mounting smbfs share will cause a panic. Fix setting/restoring vnet context when needed. PR: kern/168077 Submitted by: dteske

Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs. This means that their use is restricted to a single C file.

Change some variables from int to size_t. This is more accurate since

2011-01-08T23:06:54Z

these variables represent sizes in one capacity or another. There is no reason to allow negative numbers. Change userspace shared structure elements that get used for the modified functions from int to uint32_t, since it's not clear what userspace programs use these fields, and we do not want to break binary compatibility. This fixes a panic when corrupt or bogus data is passed into the kernel. Obtained from: NetBSD MFC after: 3 weeks

Rework socket upcalls to close some races with setup/teardown of upcalls.

2009-06-01T21:17:03Z

- Each socket upcall is now invoked with the appropriate socket buffer locked. It is not permissible to call soisconnected() with this lock held; however, so socket upcalls now return an integer value. The two possible values are SU_OK and SU_ISCONNECTED. If an upcall returns SU_ISCONNECTED, then the soisconnected() will be invoked on the socket after the socket buffer lock is dropped. - A new API is provided for setting and clearing socket upcalls. The API consists of soupcall_set() and soupcall_clear(). - To simplify locking, each socket buffer now has a separate upcall. - When a socket upcall returns SU_ISCONNECTED, the upcall is cleared from the receive socket buffer automatically. Note that a SO_SND upcall should never return SU_ISCONNECTED. - All this means that accept filters should now return SU_ISCONNECTED instead of calling soisconnected() directly. They also no longer need to explicitly clear the upcall on the new socket. - The HTTP accept filter still uses soupcall_set() to manage its internal state machine, but other accept filters no longer have any explicit knowlege of socket upcall internals aside from their return value. - The various RPC client upcalls currently drop the socket buffer lock while invoking soreceive() as a temporary band-aid. The plan for the future is to add a new flag to allow soreceive() to be called with the socket buffer locked. - The AIO callback for socket I/O is now also invoked with the socket buffer locked. Previously sowakeup() would drop the socket buffer lock only to call aio_swake() which immediately re-acquired the socket buffer lock for the duration of the function call.

Implement device cloning for /dev/nsmb, the netsmb control pseudo-device.

2008-11-03T14:23:15Z

The smb library in userspace already knows how to deal with this type of cloning. This also corrects a leak in which the netsmb kernel module could not be unloaded if device nodes had been stat'd but not open'd. Discussed with: kib
