A similar issue was fixed for lockd in 9a1b6bf818e7 ("LOCKD: Don't call utsname()->nodename from nlmclnt_setlockargs"), so this patch attempts something similar for 9pfs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | RDMA needs to post a buffer for each incoming reply. Hence it needs to keep count of these and needs to be aware of whether a flushed request has received a reply or not. This patch adds the cancelled() callback to the transport modules. It is called when RFLUSH has been received and that the corresponding request will never receive a reply.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code keeps track of the number of buffers posted in the RQ, and will prevent it from overflowing. But it does so by simply dropping post requests (And leaking memory in the process). When this happens there will actually be too few buffers posted, and soon the 9P server will complain about 'RNR retry counter exceeded' errors. Instead, use a semaphore, and block until the RQ is ready for another buffer to be posted. Signed-off-by: Simon Derr <simon.derr@bull.net> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code assumes that when a request in the request array does have a tc, it also has a rc. This is normally true, but not always : when using RDMA, req->rc will temporarily be set to NULL after the request has been sent. That is usually OK though, as when the reply arrives, req->rc will be reassigned to a sane value before the request is recycled. But there is a catch : if the request is flushed, the reply will never arrive, and req->rc will be NULL, but not req->tc. This patch fixes p9_tag_alloc to take this into account.

| |/ | | | | | | | | | | | | | | | | | | | | For zero copy request, error will be encoded in the user space buffer. So copy the error code correctly using copy_from_user. Here we use the extra bytes we allocate for zero copy request. If total error details are more than P9_ZC_HDR_SZ - 7 bytes, we return -EFAULT. The patch also avoid a memory allocation in the error path. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.

I do my best to document that if you care about limiting your unprivileged users that when you have the user namespace support enabled you will need to enable memory control groups. There is a minor bug fix to prevent overflowing the stack if someone creates way too many user namespaces. The bulk of the changes are a continuation of the kuid/kgid push down work through the filesystems. These changes make using uids and gids typesafe which ensures that these filesystems are safe to use when multiple user namespaces are in use. The filesystems converted for 3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The changes for these filesystems were a little more involved so I split the changes into smaller hopefully obviously correct changes. XFS is the only filesystem that remains. I was hoping I could get that in this release so that user namespace support would be enabled with an allyesconfig or an allmodconfig but it looks like the xfs changes need another couple of days before it they are ready." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (93 commits) cifs: Enable building with user namespaces enabled. cifs: Convert struct cifs_ses to use a kuid_t and a kgid_t cifs: Convert struct cifs_sb_info to use kuids and kgids cifs: Modify struct smb_vol to use kuids and kgids cifs: Convert struct cifsFileInfo to use a kuid cifs: Convert struct cifs_fattr to use kuid and kgids cifs: Convert struct tcon_link to use a kuid. cifs: Modify struct cifs_unix_set_info_args to hold a kuid_t and a kgid_t cifs: Convert from a kuid before printing current_fsuid cifs: Use kuids and kgids SID to uid/gid mapping cifs: Pass GLOBAL_ROOT_UID and GLOBAL_ROOT_GID to keyring_alloc cifs: Use BUILD_BUG_ON to validate uids and gids are the same size cifs: Override unmappable incoming uids and gids nfsd: Enable building with user namespaces enabled. nfsd: Properly compare and initialize kuids and kgids nfsd: Store ex_anon_uid and ex_anon_gid as kuids and kgids nfsd: Modify nfsd4_cb_sec to use kuids and kgids nfsd: Handle kuids and kgids in the nfs4acl to posix_acl conversion nfsd: Convert nfsxdr to use kuids and kgids nfsd: Convert nfs3xdr to use kuids and kgids ...

| | | | | | | | | | | | | | | | When using a virtio transport, the 9p net device may pass the physical address of a kernel buffer to userspace via a scatterlist inside a virtqueue. If the kernel buffer is mapped outside of the linear mapping (e.g. highmem), then virt_to_page will return a bogus value and we will populate the scatterlist with junk.

If this value is then passed to ERR_PTR() it will not be properly detected as an error code by IS_ERR() and as a result the kernel will dereference an invalid pointer. This patch tries to avoid this.

A bunch of relatively minor races got fixed in process, plus an ext4 struct file leak. - related thing - fget_light() partially unuglified; see fdget() in there (and yes, it generates the code as good as we used to have). - also related - bits of Cyrill's procfs stuff that got entangled into that work; _not_ all of it, just the initial move to fs/proc/fd.c and switch of fdinfo to seq_file. - Alex's fs/coredump.c spiltoff - the same story, had been easier to take that commit than mess with conflicts.
