The firmware PXE EPROM version detection is failing due to passing the wrong parameter into firmware query function. Also, the version printing function has an extraneous newline. Signed-off-by:

Reorder the commands to be in the inverse order of their allocations (instead of the random order they appear to be in), propagate return code on errors from pci_request_region and register_netdev, reduce the config_dev_cnt and total_dev_cnt counters on remove, and return the correct error code for vdev->vpaths kzalloc failures. Also, prevent leaking of vdev->vpaths memory and netdev in vxge_probe error path due to freeing for these not occurring in vxge_device_unregister. Signed-off-by:

Linux Socket Filters can already be successfully attached and detached on unix sockets with setsockopt(sockfd, SOL_SOCKET, SO_{ATTACH,DETACH}_FILTER, ...). See: Documentation/networking/filter.txt But the filter was never used in the unix socket code so it did not work. This patch uses sk_filter() to filter buffers before delivery. This short program demonstrates the problem on SOCK_DGRAM. int main(void) { int i, j, ret; int sv[2]; struct pollfd fds[2]; char *message = "Hello world!"; char buffer[64]; struct sock_filter ins[32] = {{0,},}; struct sock_fprog filter; socketpair(AF_UNIX, SOCK_DGRAM, 0, sv); for (i = 0 ; i < 2 ; i++) { fds[i].fd = sv[i]; fds[i].events = POLLIN; fds[i].revents = 0; } for(j = 1 ; j < 13 ; j++) { /* Set a socket filter to truncate the message */ memset(ins, 0, sizeof(ins)); ins[0].code = BPF_RET|BPF_K; ins[0].k = j; filter.len = 1; filter.filter = ins; setsockopt(sv[1], SOL_SOCKET, SO_ATTACH_FILTER, &filter, sizeof(filter)); /* send a message */ send(sv[0], message, strlen(message) + 1, 0); /* The filter should let the message pass but truncated. */ poll(fds, 2, 0); /* Receive the truncated message*/ ret = recv(sv[1], buffer, 64, 0); printf("received %d bytes, expected %d\n", ret, j); } for (i = 0 ; i < 2 ; i++) close(sv[i]); return 0; } Signed-off-by:Alban Crequy <alban.crequy@collabora.co.uk> Reviewed-by:

In netif_skb_features() we return only the features that are valid for vlans if we have a vlan packet. However, we should not mask out NETIF_F_HW_VLAN_TX since it enables transmission of vlan tags and is obviously valid. Reported-by:

In drivers/net/ns83820.c::ns83820_init_one() we dynamically allocate memory via alloc_etherdev(). We then call PRIV() on the returned storage which is 'return netdev_priv()'. netdev_priv() takes the pointer it is passed and adds 'ALIGN(sizeof(struct net_device), NETDEV_ALIGN)' to it and returns it. Then we test the resulting pointer for NULL, which it is unlikely to be at this point, and later dereference it. This will go bad if alloc_etherdev() actually returned NULL. This patch reworks the code slightly so that we test for a NULL pointer (and return -ENOMEM) directly after calling alloc_etherdev(). Signed-off-by:

When a network namespace is created (via CLONE_NEWNET), the loopback interface is automatically added to the new namespace, triggering a printk in ipv6_add_dev() if CONFIG_IPV6_PRIVACY is set. This is problematic for applications which use CLONE_NEWNET as part of a sandbox, like Chromium's suid sandbox or recent versions of vsftpd. On a busy machine, it can lead to thousands of useless "lo: Disabled Privacy Extensions" messages appearing in dmesg. It's easy enough to check the status of privacy extensions via the use_tempaddr sysctl, so just removing the printk seems like the most sensible solution. Signed-off-by:

Starting from perf_event_alloc()->perf_init_event(), the kernel assumes that event->cpu is either -1 or the valid CPU number. Change perf_event_alloc() to validate this argument early. This also means we can remove the similar check in find_get_context(). Signed-off-by:

While most users of a physical Malta board are using the serial port as the console, a lot of QEMU users would prefer to interact with a graphical console. Enable the Cirrus FB support in the Malta default configuration to make that possible. Note that the default console will still be the serial port, users have to pass "console=tty0" to the kernel to use the Cirrus FB. Signed-off-by:

Just do what everyone else is doing by placing __read_mostly things in the .data.read_mostly section. mips_io_port_base can not be read-only (const) and writable (__read_mostly) at the same time. One of them has to go, so I chose to eliminate the __read_mostly. It will still get stuck in a portion of memory that is not adjacent to things that are written, and thus not be on a dirty cache line, for whatever that is worth. Signed-off-by:
