Currently, if the server is doing NFSv4.2 and supports labeled NFS, then our on-the-wire READDIR request ends up asking for the label information, which is then ignored unless we're doing readdirplus.

The IDTE instruction used to flush TLB entries for a specific address space uses the address-space-control element (ASCE) to identify affected TLB entries. The upgrade of a page table adds a new top level page table which changes the ASCE. The TLB entries associated with the old ASCE need to be flushed and the ASCE for the address space needs to be replaced synchronously on all CPUs which currently use it. The concept of a lazy ASCE update with an exception handler is broken. Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

Introduced in f9e42b85 ("net: sctp: sideeffect: throw BUG if primary_path is NULL"), we intended to find a buggy assoc that's part of the assoc hash table with a primary_path that is NULL. However, we better remove the BUG_ON for now and find a more suitable place to assert for these things as Mark reports that this also triggers the bug when duplication cookie processing happens, and the assoc is not part of the hash table (so all good in this case). Such a situation can for example easily be reproduced by: tc qdisc add dev eth0 root handle 1: prio bands 2 priomap 1 1 1 1 1 1 tc qdisc add dev eth0 parent 1:2 handle 20: netem loss 20% tc filter add dev eth0 protocol ip parent 1: prio 2 u32 match ip \ protocol 132 0xff match u8 0x0b 0xff at 32 flowid 1:2 This drops 20% of COOKIE-ACK packets. After some follow-up discussion with Vlad we came to the conclusion that for now we should still better remove this BUG_ON() assertion, and come up with two follow-ups later on, that is, i) find a more suitable place for this assertion, and possibly ii) have a special allocator/initializer for such kind of temporary assocs.

Negative message lengths make no sense -- so don't do negative queue lenghts or identifier counts. Prevent them from getting negative. Also change the underlying data types to be unsigned to avoid hairy surprises with sign extensions in cases where those variables get evaluated in unsigned expressions with bigger data types, e.g size_t. In case a user still wants to have "unlimited" sizes she could just use INT_MAX instead.

When CONFIG_CIFS_STATS2 enabled query adapter info for debugging It is easy now in SMB3 to query the information about the server's network interfaces (and at least Windows 8 and above do this, if not other clients) there are some useful pieces of information you can get including: - all of the network interfaces that the server advertises (not just the one you are mounting over), and with SMB3 supporting multichannel this helps with more than just failover (also aggregating multiple sockets under one mount) - whether the adapter supports RSS (useful to know if you want to estimate whether setting up two or more socket connections to the same address is going to be faster due to RSS offload in the adapter) - whether the server supports RDMA - whether the server has IPv6 interfaces (if you connected over IPv4 but prefer IPv6 e.g.) - what the link speed is (you might want to reconnect over a higher speed interface if available) (Of course we could also rerequest this on every mount cheaplly to the same server, as Windows apparently does, so we can update the adapter info on new mounts, and also on every reconnect if the network interface drops temporarily - so we don't have to rely on info from the first mount to this server) It is trivial to request this information - and certainly will be useful when we get to the point of doing multichannel (and eventually RDMA), but some of this (linkspeed etc.) info may help for debugging in the meantime. Enable this request when CONFIG_CIFS_STATS2 is on (only for smb3 mounts since it is an SMB3 or later ioctl). Signed-off-by: NSteve French <smfrench@gmail.com>

An earlier patch allowed setting the per-file compression flag "chattr +c filename" on an smb2 or smb3 mount, and also allowed lsattr to return whether a file on a cifs, or smb2/smb3 mount was compressed. This patch extends the ability to set the per-file compression flag to the cifs protocol, which uses a somewhat different IOCTL mechanism than SMB2, although the payload (the flags stored in the compression_state) are the same.

In SMB3 it is now possible to query the file system alignment info, and the preferred (for performance) sector size and whether the underlying disk has no seek penalty (like SSD). Query this information at mount time for SMB3, and make it visible in /proc/fs/cifs/DebugData for debugging purposes. This alignment information and preferred sector size info will be helpful for the copy offload patches to setup the right chunks in the CopyChunk requests. Presumably the knowledge that the underlying disk is SSD could also help us make better readahead and writebehind decisions (something to look at in the future).

Currently SMB2 and SMB3 mounts do not query the device information at mount time from the server as is done for cifs. These can be useful for debugging. This is a minor patch, that extends the previous one (which added ability to query file system attributes at mount time - this returns the device characteristics - also via in /proc/fs/cifs/DebugData) Signed-off-by: NSteve French <smfrench@gmail.com>

Send a smb session logoff request before removing smb session off of the list. On a signed smb session, remvoing a session off of the list before sending a logoff request results in server returning an error for lack of smb signature. Never seen an error during smb logoff, so as per MS-SMB2 3.2.5.1, not sure how an error during logoff should be retried. So for now, if a server returns an error to a logoff request, log the error and remove the session off of the list.

The multiplex identifier (MID) in the SMB header is only ever used by the client, in conjunction with PID, to match responses from the server. As such, the endianess of the MID is not important. However, When tracing packet sequences on the wire, protocol analyzers such as wireshark display MID as little endian. It is much more informative for the on-the-wire MID sequences to match debug information emitted by the CIFS driver. Therefore, one should write and read MID in the SMB header assuming it is always little endian. Observed from wireshark during the protocol negotiation and session setup: Multiplex ID: 256 Multiplex ID: 256 Multiplex ID: 512 Multiplex ID: 512 Multiplex ID: 768 Multiplex ID: 768 After this patch on-the-wire MID values begin at 1 and increase monotonically. Introduce get_next_mid64() for the internal consumers that use the full 64 bit multiplex identifier. Introduce the helpers get_mid() and compare_mid() to make the endian translation clear.

A vmalloc fault needs to sync up PGD/PTE entry from init_mm to current task's "active_mm". ARC vmalloc fault handler however was using mm. A vmalloc fault for non user task context (actually pre-userland, from init thread's open for /dev/console) caused the handler to deref NULL mm (for mm->pgd) The reasons it worked so far is amazing: 1. By default (!SMP), vmalloc fault handler uses a cached value of PGD. In SMP that MMU register is repurposed hence need for mm pointer deref. 2. In pre-3.12 SMP kernel, the problem triggering vmalloc didn't exist in pre-userland code path - it was introduced with commit 20bafb3d "n_tty: Move buffers into n_tty_data" Signed-off-by: NVineet Gupta <vgupta@synopsys.com> Cc: Gilad Ben-Yossef <gilad@benyossef.com> Cc: Noam Camus <noamc@ezchip.com> Cc: stable@vger.kernel.org #3.10 and 3.11 Cc: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

We don't validate iph->ihl which may lead a dead loop if we meet a IPIP skb whose iph->ihl is zero. Fix this by failing immediately when iph->ihl is evil (less than 5).

Steffen Klassert says: ==================== 1) Fix a possible race on ipcomp scratch buffers because of too early enabled siftirqs. From Michal Kubecek. 2) The current xfrm garbage collector threshold is too small for some workloads, resulting in bad performance on these workloads. Increase the threshold from 1024 to 32768. 3) Some codepaths might not have a dst_entry attached to the skb when calling xfrm_decode_session(). So add a check to prevent a null pointer dereference in this case. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch uses CONFIG_PAGE_OFFSET to filter symbols which are not in kernel address space because these symbols are generally for generating code purpose and can't be run at kernel mode, so we needn't keep them in /proc/kallsyms. For example, on ARM there are some symbols which may be linked in relocatable code section, then perf can't parse symbols any more from /proc/kallsyms, this patch fixes the problem (introduced b9b32bf7) Cc: Russell King <linux@arm.linux.org.uk> Cc: linux-arm-kernel@lists.infradead.org Cc: Michal Marek <mmarek@suse.cz> Signed-off-by: NMing Lei <tom.leiming@gmail.com> Signed-off-by: NRusty Russell <rusty@rustcorp.com.au> Cc: stable@vger.kernel.org
