[ Upstream commit 233135b7 ] This adds a name to each buf_ops structure, so that if a verifier fails we can print the type of verifier that failed it. Should be a slight debugging aid, I hope. Signed-off-by:

[ Upstream commit 759c0114 ] On no-so-small systems, it is possible for a single process to cause an OOM condition by filling large pipes with data that are never read. A typical process filling 4000 pipes with 1 MB of data will use 4 GB of memory. On small systems it may be tricky to set the pipe max size to prevent this from happening. This patch makes it possible to enforce a per-user soft limit above which new pipes will be limited to a single page, effectively limiting them to 4 kB each, as well as a hard limit above which no new pipes may be created for this user. This has the effect of protecting the system against memory abuse without hurting other users, and still allowing pipes to work correctly though with less data at once. The limit are controlled by two new sysctls : pipe-user-pages-soft, and pipe-user-pages-hard. Both may be disabled by setting them to zero. The default soft limit allows the default number of FDs per process (1024) to create pipes of the default size (64kB), thus reaching a limit of 64MB before starting to create only smaller pipes. With 256 processes limited to 1024 FDs each, this results in 1024*64kB + (256*1024 - 1024) * 4kB = 1084 MB of memory allocated for a user. The hard limit is disabled by default to avoid breaking existing applications that make intensive use of pipes (eg: for splicing). Reported-by: socketpair@gmail.com Reported-by:

The problem occurs because netem is not prepared to handle GSO packets (as it uses skb_checksum_help in its enqueue path, which cannot manipulate these frames). The solution I think is to simply segment the skb in a simmilar fashion to the way we do in __dev_queue_xmit (via validate_xmit_skb), with some minor changes. When we decide to corrupt an skb, if the frame is GSO, we segment it, corrupt the first segment, and enqueue the remaining ones. tested successfully by myself on the latest net kernel, to which this applies Signed-off-by:

[ Upstream commit 8358b02b ] When bpf(BPF_PROG_LOAD, ...) was invoked with a BPF program whose bytecode references a non-map file descriptor as a map file descriptor, the error handling code called fdput() twice instead of once (in __bpf_map_get() and in replace_map_fd_with_map_ptr()). If the file descriptor table of the current task is shared, this causes f_count to be decremented too much, allowing the struct file to be freed while it is still in use (use-after-free). This can be exploited to gain root privileges by an unprivileged user. This bug was introduced in commit 0246e64d ("bpf: handle pseudo BPF_LD_IMM64 insn"), but is only exploitable since commit 1be7f75d ("bpf: enable non-root eBPF programs") because previously, CAP_SYS_ADMIN was required to reach the vulnerable code.

[ Upstream commit f43bfaed ] atl2 includes NETIF_F_SG in hw_features even though it has no support for non-linear skbs. This bug was originally harmless since the driver does not claim to implement checksum offload and that used to be a requirement for SG. Now that SG and checksum offload are independent features, if you explicitly enable SG *and* use one of the rare protocols that can use SG without checkusm offload, this potentially leaks sensitive information (before you notice that it just isn't working). Therefore this obscure bug has been designated CVE-2016-2117. Reported-by:

[ Upstream commit d6d5e999 ] For local routes that require a particular output interface we do not want to cache the result. Caching the result causes incorrect behaviour when there are multiple source addresses on the interface. The end result being that if the intended recipient is waiting on that interface for the packet he won't receive it because it will be delivered on the loopback interface and the IP_PKTINFO ipi_ifindex will be set to the loopback interface as well. This can be tested by running a program such as "dhcp_release" which attempts to inject a packet on a particular interface so that it is received by another program on the same board. The receiving process should see an IP_PKTINFO ipi_ifndex value of the source interface (e.g., eth1) instead of the loopback interface (e.g., lo). The packet will still appear on the loopback interface in tcpdump but the important aspect is that the CMSG info is correct.

[ Upstream commit d1a65f17 ] _batadv_update_route rcu_derefences orig_ifinfo->router outside of a spinlock protected region to print some information messages to the debug log. But this pointer is not checked again when the new pointer is assigned in the spinlock protected region. Thus is can happen that the value of orig_ifinfo->router changed in the meantime and thus the reference counter of the wrong router gets reduced after the spinlock protected region. Just rcu_dereferencing the value of orig_ifinfo->router inside the spinlock protected region (which also set the new pointer) is enough to get the correct old router object.

[ Upstream commit 8148a73c ] If /proc/<PID>/environ gets read before the envp[] array is fully set up in create_{aout,elf,elf_fdpic,flat}_tables(), we might end up trying to read more bytes than are actually written, as env_start will already be set but env_end will still be zero, making the range calculation underflow, allowing to read beyond the end of what has been written. Fix this as it is done for /proc/<PID>/cmdline by testing env_end for zero. It is, apparently, intentionally set last in create_*_tables(). This bug was found by the PaX size_overflow plugin that detected the arithmetic underflow of 'this_len = env_end - (env_start + src)' when env_end is still zero. The expected consequence is that userland trying to access /proc/<PID>/environ of a not yet fully set up process may get inconsistent data as we're in the middle of copying in the environment variables.

This is necessary for the RealView PBA8 which has two SP810 blocks: the second block will not register its clocks unless every clock on every instance is unique and results in boot logs like this: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 0 at ../drivers/clk/versatile/clk-sp810.c:137 clk_sp810_of_setup+0x110/0x154() Modules linked in: CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.5.0-rc2-00030-g352718fc39f6-dirty #225 Hardware name: ARM RealView Machine (Device Tree Support) [<c00167f8>] (unwind_backtrace) from [<c0013204>] (show_stack+0x10/0x14) [<c0013204>] (show_stack) from [<c01a049c>] (dump_stack+0x84/0x9c) [<c01a049c>] (dump_stack) from [<c0024990>] (warn_slowpath_common+0x74/0xb0) [<c0024990>] (warn_slowpath_common) from [<c0024a68>] (warn_slowpath_null+0x1c/0x24) [<c0024a68>] (warn_slowpath_null) from [<c051eb44>] (clk_sp810_of_setup+0x110/0x154) [<c051eb44>] (clk_sp810_of_setup) from [<c051e3a4>] (of_clk_init+0x12c/0x1c8) [<c051e3a4>] (of_clk_init) from [<c0504714>] (time_init+0x20/0x2c) [<c0504714>] (time_init) from [<c0501b18>] (start_kernel+0x244/0x3c4) [<c0501b18>] (start_kernel) from [<7000807c>] (0x7000807c) ---[ end trace cb88537fdc8fa200 ]--- Cc: Michael Turquette <mturquette@baylibre.com> Cc: Pawel Moll <pawel.moll@arm.com> Fixes: 6e973d2c "clk: vexpress: Add separate SP810 driver" Signed-off-by:

[ Upstream commit da6ccaaa ] Make the "Attempted send on closed socket" error messages generated in nbd_request_handler() ratelimited. When the nbd socket is shutdown, the nbd_request_handler() function emits an error message for every request remaining in its queue. If the queue is large, this will spam a large amount of messages to the log. There's no need for a separate error message for each request, so this patch ratelimits it. In the specific case this was found, the system was virtual and the error messages were logged to the serial port, which overwhelmed it.

[ Upstream commit 7617a24f ] The IPVS SIP persistence engine is not able to parse the SIP header "Call-ID" when such header is inserted in the first positions of the SIP message. When IPVS is configured with "--pe sip" option, like for example: ipvsadm -A -u 1.2.3.4:5060 -s rr --pe sip -p 120 -o some particular messages (see below for details) do not create entries in the connection template table, which can be listed with: ipvsadm -Lcn --persistent-conn Problematic SIP messages are SIP responses having "Call-ID" header positioned just after message first line: SIP/2.0 200 OK [Call-ID header here] [rest of the headers] When "Call-ID" header is positioned down (after a few other headers) it is correctly recognized. This is due to the data offset used in get_callid function call inside ip_vs_pe_sip.c file: since dptr already points to the start of the SIP message, the value of dataoff should be initially 0. Otherwise the header is searched starting from some bytes after the first character of the SIP message. Fixes: 758ff033 ("IPVS: sip persistence engine") Signed-off-by:

[ Upstream commit a6ab1e81 ] sunrpc_cache_pipe_upcall() can detect a race if CACHE_PENDING is no longer set. In this case it aborts the queuing of the upcall. However it has already taken a new counted reference on "h" and doesn't "put" it, even though it frees the data structure holding the reference. So let's delay the "cache_get" until we know we need it. Fixes: f9e1aedc ("sunrpc/cache: remove races with queuing an upcall.") Signed-off-by:
