| * nfs: enable swap on NFSMel Gorman2012-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the new swapfile a_ops for NFS and hook up ->direct_IO. This will set the NFS socket to SOCK_MEMALLOC and run socket reconnect under PF_MEMALLOC as well as reset SOCK_MEMALLOC before engaging the protocol ->connect() method. PF_MEMALLOC should allow the allocation of struct socket and related objects and the early (re)setting of SOCK_MEMALLOC should allow us to receive the packets required for the TCP connection buildup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch kernel will panic on LockD start, because lockd_up() checks lockd_up_net() result for negative value.

The VM ends up calling ->releasepage to get more memory, and it tries to do a blocking commit. That commit can't succeed however without a connected socket, so we deadlock. Fix this by setting PF_FSTRANS on the workqueue task prior to doing the socket allocation, and having nfs_release_page check for that flag when deciding whether to do a commit call. Also, set PF_FSTRANS unconditionally in rpc_async_schedule since that function can also do allocations sometimes.

| * | SUNRPC/cache: fix reporting of expired cache entries in 'content' file.NeilBrown2012-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Entries that are in a sunrpc cache but are not valid should be reported with a leading '#' so they look like a comment. Commit d202cce8963d9 (sunrpc: never return expired entries in sunrpc_cache_lookup) broke this for expired entries. This particularly applies to entries that have been replaced by newer entries. sunrpc_cache_update sets the expiry of the replaced entry to '0', but it remains in the cache until the next 'cache_clean'. The result is that if you echo 0 2000000000 1 0 > /proc/net/rpc/auth.unix.gid/channel several times, then cat /proc/net/rpc/auth.unix.gid/content It will display multiple entries for the one uid, which is at least confusing: #uid cnt: gids... 0 1: 0 0 1: 0 0 1: 0 With this patch, expired entries are marked as comments so you get #uid cnt: gids... 0 1: 0 # 0 1: 0 # 0 1: 0 These expired entries will never be seen by cache_check() as they are always *after* a non-expired entry with the same key - so the extra check is only needed in c_show() Signed-off-by: NeilBrown <neilb@suse.de> -- It's not a big problem, but it had me confused for a while, so it could well confuse others.

This list does not include any non-GSS flavors that have been registered with the RPC client. nfs4_find_root_sec() currently adds these extra flavors by hand. Instead, nfs4_find_root_sec() should be looking at the set of flavors that have been explicitly registered via rpcauth_register(). And, other areas of code will soon need the same kind of list that contains all flavors the kernel currently knows about (see below). Rather than cloning the open-coded logic in nfs4_find_root_sec() to those new places, introduce a generic RPC function that generates a full list of registered auth flavors and pseudoflavors. A new rpc_authops method is added that lists a flavor's pseudoflavors, if it has any. I encountered an interesting module loader loop when I tried to get the RPC client to invoke gss_mech_list_pseudoflavors() by name. This patch is a pre-requisite for server trunking discovery, and a pre-requisite for fixing up the in-kernel mount client to do better automatic security flavor selection.

Highlights: - Config guards make it impossible to enable the user namespace and code that has not been converted to be user namespace safe. - Use of the new kuid_t type ensures the if you somehow get past the config guards the kernel will encounter type errors if you enable user namespaces and attempt to compile in code whose permission checks have not been updated to be user namespace safe. - All uids from child user namespaces are mapped into the initial user namespace before they are processed. Removing the need to add an additional check to see if the user namespace of the compared uids remains the same. - With the user namespaces compiled out the performance is as good or better than it is today. - For most operations absolutely nothing changes performance or operationally with the user namespace enabled. - The worst case performance I could come up with was timing 1 billion cache cold stat operations with the user namespace code enabled. This went from 156s to 164s on my laptop (or 156ns to 164ns per stat operation). - (uid_t)-1 and (gid_t)-1 are reserved as an internal error value. Most uid/gid setting system calls treat these value specially anyway so attempting to use -1 as a uid would likely cause entertaining failures in userspace. - If setuid is called with a uid that can not be mapped setuid fails. I have looked at sendmail, login, ssh and every other program I could think of that would call setuid and they all check for and handle the case where setuid fails. - If stat or a similar system call is called from a context in which we can not map a uid we lie and return overflowuid. The LFS experience suggests not lying and returning an error code might be better, but the historical precedent with uids is different and I can not think of anything that would break by lying about a uid we can't map. - Capabilities are localized to the current user namespace making it safe to give the initial user in a user namespace all capabilities.

Part of this is that we can now have BPF filters not attached to sockets, and the loadbalancing function is calculated using one. 7) Francois Romieu went through the network drivers removing gratuitous uses of netdev->base_addr, perhaps some day we can remove it completely but it's used for ISA probing still. 8) Add a BPF JIT for sparc. I know, who cares, right? :-) 9) Move networking sysctl registry away from using the compatability mode interfaces in the sysctl code. From Eric W Biederman. 10) Pavel Emelyanov added a way to save and restore TCP socket state via TCP_REPAIR, TCP_REPAIR_QUEUE, and TCP_QUEUE_SEQ socket options as well as a way to forcefully bind a socket to a port via the sk->sk_reuse value SK_FORCE_REUSE. There is also a TCP_REPAIR_OPTIONS which allows to reinstante the TCP options enabled on the connection. 11) Several enhancements from Eric Dumazet that, in particular, can enhance splice performance on TCP sockets significantly. a) Reset the offset of the per-socket sendmsg page when we know we're the only use of the page in linear_to_page(). b) Add facilities such that skb->data can be backed a page rather than SLAB kmalloc'd memory. In particular devices which were receiving into linear RX buffers can now end up providing paged data. The big result is that code like splice and GRO do not have to copy any more. 12) Allow a pure sender to more gracefully handle ACK backlogs in TCP. What can happen at high rates is that the sender hasn't grown his receive buffer limits at all (he's not receiving data so really doesn't need to), but the non-data ACKs consume receive buffer space. sk_add_backlog() is too aggressive in dropping frames in this case, so relax it's requirements by using the receive buffer plus the send buffer limit as the backlog limit instead of just the former. Also from Eric Dumazet. 13) Add ipv6 support to L2TP, from Benjamin LaHaise, James Chapman, and Chris Elston. 14) Implement TCP early retransmit (RFC 5827), from Yuchung Cheng. Basically, we can start fast retransmit before hiting the dupack threshold under certain conditions. 15) New CODEL active queue management packet scheduler, from Eric Dumazet based upon initial work by Dave Taht. Basically, the big feature is that packets are dropped (or ECN bits are set) based upon how long packets live in the queue, rather than the queue length (which is what RED uses). * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1341 commits) drivers/net/stmmac: seq_file fix memory leak ipv6/exthdrs: strict Pad1 and PadN check USB: qmi_wwan: Add ZTE (Vodafone) K3520-Z USB: qmi_wwan: Add ZTE (Vodafone) K3765-Z USB: qmi_wwan: Make forced int 4 whitelist generic net/ipv4: replace simple_strtoul with kstrtoul net/ipv4/ipconfig: neaten __setup placement net: qmi_wwan: Add Vodafone/Huawei K5005 support net: cdc_ether: Add ZTE WWAN matches before generic Ethernet ipv6: use skb coalescing in reassembly ipv4: use skb coalescing in defragmentation net: introduce skb_try_coalesce() net:ipv6:fixed space issues relating to operators. net:ipv6:fixed a trailing white space issue. ipv6: disable GSO on sockets hitting dst_allfrag tg3: use netdev_alloc_frag() API net: napi_frags_skb() is static ppp: avoid false drop_monitor false positives ipv6: bool/const conversions phase2 ipx: Remove spurious NULL checking in ipx_ioctl(). ...
