2012-08-20af_packet: don't emit packet on orig fanout groupEric Leblond
If a packet is emitted on one socket in one group of fanout sockets, it is transmitted again. It is thus read again on one of the sockets of the fanout group. This result in a loop for software which generate packets when receiving one. This retransmission is not the intended behavior: a fanout group must behave like a single socket. The packet should not be transmitted on a socket if it originates from a socket belonging to the same fanout group. This patch fixes the issue by changing the transmission check to take fanout group info account.

The mdio-mux driver scans all child mdio nodes, without regard to whether the node is actually used. Some device trees include all possible mdio-mux nodes and rely on the boot loader to disable those that are not present, based on some run-time configuration. Those nodes need to be skipped.

2012-08-20dt: introduce for_each_available_child_of_node, of_get_next_available_childTimur Tabi
Macro for_each_child_of_node() makes it easy to iterate over all of the children for a given device tree node, including those nodes that are marked as unavailable (i.e. status = "disabled"). Introduce for_each_available_child_of_node(), which is like for_each_child_of_node(), but it automatically skips unavailable nodes. This also requires the introduction of helper function of_get_next_available_child(), which returns the next available child node.

2012-08-20crypto: caam - fix possible deadlock conditionKim Phillips
commit "crypto: caam - use non-irq versions of spinlocks for job rings" made two bad assumptions: (a) The caam_jr_enqueue lock isn't used in softirq context. Not true: jr_enqueue can be interrupted by an incoming net interrupt and the received packet may be sent for encryption, via caam_jr_enqueue in softirq context, thereby inducing a deadlock. This is evidenced when running netperf over an IPSec tunnel between two P4080's, with spinlock debugging turned on: [ 892.092569] BUG: spinlock lockup on CPU#7, netperf/10634, e8bf5f70 [ 892.098747] Call Trace: [ 892.101197] [eff9fc10] [c00084c0] show_stack+0x48/0x15c (unreliable) [ 892.107563] [eff9fc50] [c0239c2c] do_raw_spin_lock+0x16c/0x174 [ 892.113399] [eff9fc80] [c0596494] _raw_spin_lock+0x3c/0x50 [ 892.118889] [eff9fc90] [c0445e74] caam_jr_enqueue+0xf8/0x250 [ 892.124550] [eff9fcd0] [c044a644] aead_decrypt+0x6c/0xc8 [ 892.129625] BUG: spinlock lockup on CPU#5, swapper/5/0, e8bf5f70 [ 892.129629] Call Trace: [ 892.129637] [effa7c10] [c00084c0] show_stack+0x48/0x15c (unreliable) [ 892.129645] [effa7c50] [c0239c2c] do_raw_spin_lock+0x16c/0x174 [ 892.129652] [effa7c80] [c0596494] _raw_spin_lock+0x3c/0x50 [ 892.129660] [effa7c90] [c0445e74] caam_jr_enqueue+0xf8/0x250 [ 892.129666] [effa7cd0] [c044a644] aead_decrypt+0x6c/0xc8 [ 892.129674] [effa7d00] [c0509724] esp_input+0x178/0x334 [ 892.129681] [effa7d50] [c0519778] xfrm_input+0x77c/0x818 [ 892.129688] [effa7da0] [c050e344] xfrm4_rcv_encap+0x20/0x30 [ 892.129697] [effa7db0] [c04b90c8] ip_local_deliver+0x190/0x408 [ 892.129703] [effa7de0] [c04b966c] ip_rcv+0x32c/0x898 [ 892.129709] [effa7e10] [c048b998] __netif_receive_skb+0x27c/0x4e8 [ 892.129715] [effa7e80] [c048d744] netif_receive_skb+0x4c/0x13c [ 892.129726] [effa7eb0] [c03c28ac] _dpa_rx+0x1a8/0x354 [ 892.129732] [effa7ef0] [c03c2ac4] ingress_rx_default_dqrr+0x6c/0x108 [ 892.129742] [effa7f10] [c0467ae0] qman_poll_dqrr+0x170/0x1d4 [ 892.129748] [effa7f40] [c03c153c] dpaa_eth_poll+0x20/0x94 [ 892.129754] [effa7f60] [c048dbd0] net_rx_action+0x13c/0x1f4 [ 892.129763] [effa7fa0] [c003d1b8] __do_softirq+0x108/0x1b0 [ 892.129769] [effa7ff0] [c000df58] call_do_softirq+0x14/0x24 [ 892.129775] [ebacfe70] [c0004868] do_softirq+0xd8/0x104 [ 892.129780] [ebacfe90] [c003d5a4] irq_exit+0xb8/0xd8 [ 892.129786] [ebacfea0] [c0004498] do_IRQ+0xa4/0x1b0 [ 892.129792] [ebacfed0] [c000fad8] ret_from_except+0x0/0x18 [ 892.129798] [ebacff90] [c0009010] cpu_idle+0x94/0xf0 [ 892.129804] [ebacffb0] [c059ff88] start_secondary+0x42c/0x430 [ 892.129809] [ebacfff0] [c0001e28] __secondary_start+0x30/0x84 [ 892.281474] [ 892.282959] [eff9fd00] [c0509724] esp_input+0x178/0x334 [ 892.288186] [eff9fd50] [c0519778] xfrm_input+0x77c/0x818 [ 892.293499] [eff9fda0] [c050e344] xfrm4_rcv_encap+0x20/0x30 [ 892.299074] [eff9fdb0] [c04b90c8] ip_local_deliver+0x190/0x408 [ 892.304907] [eff9fde0] [c04b966c] ip_rcv+0x32c/0x898 [ 892.309872] [eff9fe10] [c048b998] __netif_receive_skb+0x27c/0x4e8 [ 892.315966] [eff9fe80] [c048d744] netif_receive_skb+0x4c/0x13c [ 892.321803] [eff9feb0] [c03c28ac] _dpa_rx+0x1a8/0x354 [ 892.326855] [eff9fef0] [c03c2ac4] ingress_rx_default_dqrr+0x6c/0x108 [ 892.333212] [eff9ff10] [c0467ae0] qman_poll_dqrr+0x170/0x1d4 [ 892.338872] [eff9ff40] [c03c153c] dpaa_eth_poll+0x20/0x94 [ 892.344271] [eff9ff60] [c048dbd0] net_rx_action+0x13c/0x1f4 [ 892.349846] [eff9ffa0] [c003d1b8] __do_softirq+0x108/0x1b0 [ 892.355338] [eff9fff0] [c000df58] call_do_softirq+0x14/0x24 [ 892.360910] [e7169950] [c0004868] do_softirq+0xd8/0x104 [ 892.366135] [e7169970] [c003d5a4] irq_exit+0xb8/0xd8 [ 892.371101] [e7169980] [c0004498] do_IRQ+0xa4/0x1b0 [ 892.375979] [e71699b0] [c000fad8] ret_from_except+0x0/0x18 [ 892.381466] [e7169a70] [c0445e74] caam_jr_enqueue+0xf8/0x250 [ 892.387127] [e7169ab0] [c044ad4c] aead_givencrypt+0x6ac/0xa70 [ 892.392873] [e7169b20] [c050a0b8] esp_output+0x2b4/0x570 [ 892.398186] [e7169b80] [c0519b9c] xfrm_output_resume+0x248/0x7c0 [ 892.404194] [e7169bb0] [c050e89c] xfrm4_output_finish+0x18/0x28 [ 892.410113] [e7169bc0] [c050e8f4] xfrm4_output+0x48/0x98 [ 892.415427] [e7169bd0] [c04beac0] ip_local_out+0x48/0x98 [ 892.420740] [e7169be0] [c04bec7c] ip_queue_xmit+0x16c/0x490 [ 892.426314] [e7169c10] [c04d6128] tcp_transmit_skb+0x35c/0x9a4 [ 892.432147] [e7169c70] [c04d6f98] tcp_write_xmit+0x200/0xa04 [ 892.437808] [e7169cc0] [c04c8ccc] tcp_sendmsg+0x994/0xcec [ 892.443213] [e7169d40] [c04eebfc] inet_sendmsg+0xd0/0x164 [ 892.448617] [e7169d70] [c04792f8] sock_sendmsg+0x8c/0xbc [ 892.453931] [e7169e40] [c047aecc] sys_sendto+0xc0/0xfc [ 892.459069] [e7169f10] [c047b934] sys_socketcall+0x110/0x25c [ 892.464729] [e7169f40] [c000f480] ret_from_syscall+0x0/0x3c (b) since the caam_jr_dequeue lock is only used in bh context, then semantically it should use _bh spin_lock types. spin_lock_bh semantics are to disable back-halves, and used when a lock is shared between softirq (bh) context and process and/or h/w IRQ context. Since the lock is only used within softirq context, and this tasklet is atomic, there is no need to do the additional work to disable back halves.

It also uses a designated initializer to initialize the field enabled. A compound literal is not a constant expression. The location of the above statement isn't fully clear, but if a compound literal occurs outside the body of a function, the initializer list must consist of constant expressions.

2012-08-19alpha: take a bunch of syscalls into osf_sys.cAl Viro
New helper: current_thread_info(). Allows to do a bunch of odd syscalls in C. While we are at it, there had never been a reason to do osf_getpriority() in assembler. We also get "namespace"-aware (read: consistent with getuid(2), etc.) behaviour from getx?id() syscalls now.

2012-08-19alpha: Use new generic strncpy_from_user() and strnlen_user()Michael Cree
Similar to x86/sparc/powerpc implementations except: 1) we implement an extremely efficient has_zero()/find_zero() sequence with both prep_zero_mask() and create_zero_mask() no-operations. 2) Our output from prep_zero_mask() differs in that only the lowest eight bits are used to represent the zero bytes nevertheless it can be safely ORed with other similar masks from prep_zero_mask() and forms input to create_zero_mask(), the two fundamental properties prep_zero_mask() must satisfy. Tests on EV67 and EV68 CPUs revealed that the generic code is essentially as fast (to within 0.5% of CPU cycles) of the old Alpha specific code for large quadword-aligned strings, despite the 30% extra CPU instructions executed. In contrast, the generic code for unaligned strings is substantially slower (by more than a factor of 3) than the old Alpha specific code.

2012-08-19alpha: Don't export SOCK_NONBLOCK to user space.Michael Cree
Currently we export SOCK_NONBLOCK to user space but that conflicts with the definition from glibc leading to compilation errors in user programs (e.g. see Debian bug #658460). The generic socket.h restricts the definition of SOCK_NONBLOCK to the kernel, as does the MIPS specific socket.h, so let's do the same on Alpha.

2012-08-18x32: Use compat shims for {g,s}etsockoptMike Frysinger
Some of the arguments to {g,s}etsockopt are passed in userland pointers. If we try to use the 64bit entry point, we end up sometimes failing. For example, dhcpcd doesn't run in x32: # dhcpcd eth0 dhcpcd[1979]: version 5.5.6 starting dhcpcd[1979]: eth0: broadcasting for a lease dhcpcd[1979]: eth0: open_socket: Invalid argument dhcpcd[1979]: eth0: send_raw_packet: Bad file descriptor The code in particular is getting back EINVAL when doing: struct sock_fprog pf; setsockopt(s, SOL_SOCKET, SO_ATTACH_FILTER, &pf, sizeof(pf)); Diving into the kernel code, we can see: include/linux/filter.h: struct sock_fprog { unsigned short len; struct sock_filter __user *filter; }; net/core/sock.c: case SO_ATTACH_FILTER: ret = -EINVAL; if (optlen == sizeof(struct sock_fprog)) { struct sock_fprog fprog; ret = -EFAULT; if (copy_from_user(&fprog, optval, sizeof(fprog))) break; ret = sk_attach_filter(&fprog, sk); } break; arch/x86/syscalls/syscall_64.tbl: 54 common setsockopt sys_setsockopt 55 common getsockopt sys_getsockopt So for x64, sizeof(sock_fprog) is 16 bytes. For x86/x32, it's 8 bytes. This comes down to the pointer being 32bit for x32, which means we need to do structure size translation. But since x32 comes in directly to sys_setsockopt, it doesn't get translated like x86. After changing the syscall table and rebuilding glibc with the new kernel headers, dhcp runs fine in an x32 userland. Oddly, it seems like Linus noted the same thing during the initial port, but I guess that was missed/lost along the way: https://lkml.org/lkml/2011/8/26/452 [ hpa: tagging for -stable since this is an ABI fix. ] Bugzilla: https://bugs.gentoo.org/423649 Reported-by: Mads <mads@ab3.no> Signed-off-by: Mike Frysinger <vapier@gentoo.org> Link: http://lkml.kernel.org/r/1345320697-15713-1-git-send-email-vapier@gentoo.org Cc: H.

Without this, after a failed xfer, the runtime PM usecount will have been incremented, but not decremented causing the usecount to never reach zero after a failure. This keeps the device always runtime PM enabled which keeps the enclosing power domain active, and prevents full-chip retention/off from happening during idle.
