10 years agoLinux: Rework PAG to group conversions

Linux: Rework PAG to group conversions

The change to using a single group for PAGs on Linux led to a load
of special cases throughout the code. This patch moves the OS
dependent parts of this into the LINUX/ platform directory, and
rearranges that file so that there is a clear distinction between
the one and two group sections of the code.

Windows: Protect buffers in smb_WriteData from simultaneous writes

smb_WriteData does not properly use CM_SCACHESYNC_WRITE to
protect buffers from simultaneous writes.  Instead of simply
testing CM_SCACHESYNC_WRITE at the top of the while loop,

cm_SyncOp is now called once and cm_SyncOpDone is only called

In addition, as 'count' is unsigned, the test for count < 0

When ShutDownAndCore is called with dopanic=1, avoid trying to save
fileserver state. When we are panic'ing it is very possible that the
thread that called ShutDownAndCore is one of the background threads we
are waiting for, or that the calling thread is holding H_LOCK. Since we

just avoid trying to save state altogether, and avoid a possible
deadlock.

Remove cred pointer argument to vop_getattr and vop_setattr.
Restore VSUID and VGUID defines, but move to osi_machdep.h.
Fixup calls to vinvalbuf, create a macro to avoid too many ifdefs.
Revert incorrect definition of gop_lookupname_user.  Avoid
uninitialized use of 'code' variable in vop_access, and track
new a_accmode member name.  Remove cred pointer in VFS_STATFS.
Avoid including sys/ioctl.h in kernel mode (formerly had no
effect, it's now an error).  Avoid using an empty file as an
object file in shlibafsrpc link.  Replace suser() calls with calls
to priv_check, using defined OpenAFS privileges (thanks due to

The changes in 7b272177de4c6f78db7f2315f4e30e85ab7660bb sadly break

The code also doesn't match the comment - Linux kernels which don't
have keyrings should use afs_get_group_pag(), regardless of whether
STRUCT_TASK_HAS_CRED. It's unlikely this bit would ever bite anyone

10 years agoLinux: Flush vcaches when a mount fails
Simon Wilkinson [Sat, 19 Dec 2009 14:48:32 +0000]
Linux: Flush vcaches when a mount fails

GetVCache (well, really NewVCache) creates a new vcache, with an attached
inode, and links it into the VLRU queue, regardless of whether it is
successful in populating that vcache or not. The attached inode, on Linux,
contains a reference to the super block of the filesystem. If the created
vcache is for the root, however, and populating that vcache failes, then mount
fails, and the super block is disposed of. This leaves us with a vcache in
the VLRU queue which contains a reference to a non-existent inode.

When ShakeLooseVCaches comes along a few minutes later, it attempts to discard
this inode. However, doing so fails because the inode no longer has a valid
super block.

Avoid this trauma by ensuring all vcaches are disposed of before the super
block goes away, in the event of a mount failure.

Linux: Use splice to speed up cache storeback

This patch adds a new cache store function for Linux, which uses
splice() and direct access to the page cache, rather than doing
data copies to a temporary buffer between rx and afs. It removes
one copy, and some context switching, from the write codepath.

One side-effect here is that it will delay storebehinds from
returning control to the user. Instead of returning once the first
4k has been successfully transfered, we will wait until a cache
chunk has been transmitted. This is currently unavoidable, as we
