2013-01-18net/mlx4_core: Set number of msix vectors under SRIOV mode to firmware defaultsOr Gerlitz
The lines if (mlx4_is_mfunc(dev)) { nreq = 2; } else { which hard code the number of requested msi-x vectors under multi-function mode to two can be removed completely, since the firmware sets num_eqs and reserved_eqs appropriately Thus, the code line: nreq = min_t(int, dev->caps.num_eqs - dev->caps.reserved_eqs, nreq); is by itself sufficient and correct for all cases. Currently, for mfunc mode num_eqs = 32 and reserved_eqs = 28, hence four vectors will be enabled. This triples (one vector is used for the async events and commands EQ) the horse power provided for processing of incoming packets on netdev RSS scheme, IO initiators/targets commands processing flows, etc. Reviewed-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S.

2013-01-18net/mlx4_en: Fix bridged vSwitch configuration for non SRIOV modeYan Burman
Commit 5b4c4d36860e "mlx4_en: Allow communication between functions on same host" introduced a regression under which a bridge acting as vSwitch whose uplink is an mlx4 Ethernet device become non-operative in native (non sriov) mode. This happens since broadcast ARP requests sent by VMs were loopback-ed by the HW and hence the bridge learned VM source MACs on both the VM and the uplink ports. The fix is to place the DMAC in the send WQE only under SRIOV/eSwitch configuration or when the device is in selftest.

2013-01-18net: calxedaxgmac: throw away overrun framesRob Herring
The xgmac driver assumes 1 frame per descriptor. If a frame larger than the descriptor's buffer size is received, the frame will spill over into the next descriptor. So check for received frames that span more than one descriptor and discard them. This prevents a crash if we receive erroneous large packets.

This patch fixes the following: WARNING: vmlinux.o(.text+0x1e709c): Section mismatch in reference from the funct ion dma_controller_create() to the function .init.text:cppi_controller_start() The function dma_controller_create() references the function __init cppi_controller_start(). This is often because dma_controller_create lacks a __init annotation or the annotation of cppi_controller_start is wrong. This warning is there due to the deficiency in the commit 07a67bbb (usb: musb: Make dma_controller_create __devinit). Since the start() method is only called from musb_init_controller() which is not annotated, drop '__init' annotation from cppi_controller_start() and also cppi_pool_init() since it gets called from that function, to avoid another section mismatch warning...

Failure to do so means we can access a stale struct efivar_entry when reading/writing the file, which can result in the following oops, [ 59.978216] general protection fault: 0000 [#1] SMP [ 60.038660] CPU 9 [ 60.040501] Pid: 1001, comm: cat Not tainted 3.7.0-2.fc19.x86_64 #1 IBM System x3550 M3 -[7944I21]-/69Y4438 [ 60.050840] RIP: 0010:[<ffffffff810d5d1e>] [<ffffffff810d5d1e>] __lock_acquire+0x5e/0x1bb0 [ 60.059198] RSP: 0018:ffff880270595ce8 EFLAGS: 00010046 [ 60.064500] RAX: 0000000000000046 RBX: 0000000000000002 RCX: 0000000000000000 [ 60.071617] RDX: 0000000000000000 RSI: 0000000000000000 RDI: 6b6b6b6b6b6b6b83 [ 60.078735] RBP: ffff880270595dd8 R08: 0000000000000002 R09: 0000000000000000 [ 60.085852] R10: 6b6b6b6b6b6b6b83 R11: 0000000000000000 R12: 0000000000000000 [ 60.092971] R13: ffff88027170cd20 R14: 0000000000000000 R15: 0000000000000000 [ 60.100091] FS: 00007fc0c8ff3740(0000) GS:ffff880277000000(0000) knlGS:0000000000000000 [ 60.108164] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 60.113899] CR2: 0000000001520000 CR3: 000000026d594000 CR4: 00000000000007e0 [ 60.121016] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 60.128135] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 60.135254] Process cat (pid: 1001, threadinfo ffff880270594000, task ffff88027170cd20) [ 60.143239] Stack: [ 60.145251] ffff880270595cf8 ffffffff81021da3 ffff880270595d08 ffffffff81021e19 [ 60.152714] ffff880270595d38 ffffffff810acdb5 ffff880200000168 0000000000000086 [ 60.160175] ffff88027170d5e8 ffffffff810d25ed ffff880270595d58 ffffffff810ace7f [ 60.167638] Call Trace: [ 60.170088] [<ffffffff81021da3>] ? native_sched_clock+0x13/0x80 [ 60.176085] [<ffffffff81021e19>] ? sched_clock+0x9/0x10 [ 60.181389] [<ffffffff810acdb5>] ? sched_clock_cpu+0xc5/0x120 [ 60.187211] [<ffffffff810d25ed>] ? trace_hardirqs_off+0xd/0x10 [ 60.193121] [<ffffffff810ace7f>] ? local_clock+0x6f/0x80 [ 60.198513] [<ffffffff810d2f6f>] ? lock_release_holdtime.part.26+0xf/0x180 [ 60.205465] [<ffffffff810d7b57>] ? lock_release_non_nested+0x2e7/0x320 [ 60.212073] [<ffffffff815638bb>] ? efivarfs_file_write+0x5b/0x280 [ 60.218242] [<ffffffff810d7f41>] lock_acquire+0xa1/0x1f0 [ 60.223633] [<ffffffff81563971>] ? efivarfs_file_write+0x111/0x280 [ 60.229892] [<ffffffff8118b47c>] ? might_fault+0x5c/0xb0 [ 60.235287] [<ffffffff816f1bf6>] _raw_spin_lock+0x46/0x80 [ 60.240762] [<ffffffff81563971>] ? efivarfs_file_write+0x111/0x280 [ 60.247018] [<ffffffff81563971>] efivarfs_file_write+0x111/0x280 [ 60.253103] [<ffffffff811d307f>] vfs_write+0xaf/0x190 [ 60.258233] [<ffffffff811d33d5>] sys_write+0x55/0xa0 [ 60.263278] [<ffffffff816fbd19>] system_call_fastpath+0x16/0x1b [ 60.269271] Code: 41 0f 45 d8 4c 89 75 f0 4c 89 7d f8 85 c0 0f 84 09 01 00 00 8b 05 a3 f9 ff 00 49 89 fa 41 89 f6 41 89 d3 85 c0 0f 84 12 01 00 00 <49> 8b 02 ba 01 00 00 00 48 3d a0 07 14 82 0f 44 da 41 83 fe 01 [ 60.289431] RIP [<ffffffff810d5d1e>] __lock_acquire+0x5e/0x1bb0 [ 60.295444] RSP <ffff880270595ce8> [ 60.298928] ---[ end trace 1bbfd41a2cf6a0d8 ]--- Cc: Josh Boyer <jwboyer@redhat.com> Acked-by: Jeremy Kerr <jeremy.kerr@canonical.com> Cc: Lee, Chun-Yi <jlee@suse.com> Cc: Andy Whitcroft <apw@canonical.com> Reported-by: Lingzhu Xiang <lxiang@redhat.com> Signed-off-by: Matt Fleming <matt.fleming@intel.com>
2013-01-18efivarfs: Never return ENOENT from firmwareMatt Fleming
Files are created in efivarfs_create() before a corresponding variable is created in the firmware. This leads to users being able to read/write to the file without the variable existing in the firmware. Reading a non-existent variable currently returns -ENOENT, which is confusing because the file obviously *does* exist. Convert EFI_NOT_FOUND into -EIO which is the closest thing to "error while interacting with firmware", and should hopefully indicate to the caller that the variable is in some uninitialised state.

2013-01-18net/xfrm/xfrm_replay: avoid division by zeroNickolai Zeldovich
All of the xfrm_replay->advance functions in xfrm_replay.c check if x->replay_esn->replay_window is zero (and return if so). However, one of them, xfrm_replay_advance_bmp(), divides by that value (in the '%' operator) before doing the check, which can potentially trigger a divide-by-zero exception. Some compilers will also assume that the earlier division means the value cannot be zero later, and thus will eliminate the subsequent zero check as dead code. This patch moves the division to after the check. Signed-off-by: Nickolai Zeldovich <nickolai@csail.mit.edu> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>

2013-01-17sctp: refactor sctp_outq_teardown to insure proper re-initalizationNeil Horman
Jamie Parsons reported a problem recently, in which the re-initalization of an association (The duplicate init case), resulted in a loss of receive window space. He tracked down the root cause to sctp_outq_teardown, which discarded all the data on an outq during a re-initalization of the corresponding association, but never reset the outq->outstanding_data field to zero. I wrote, and he tested this fix, which does a proper full re-initalization of the outq, fixing this problem, and hopefully future proofing us from simmilar issues down the road.

2013-01-178250/16?50: Add support for Broadcom TruManage redirected serial portStephen Hurd
Add support for the UART device present in Broadcom TruManage capable NetXtreme chips (ie: 5761m 5762, and 5725). This implementation has a hidden transmit FIFO, so running in single-byte interrupt mode results in too many interrupts. The UART_CAP_HFIFO capability was added to track this. It continues to reload the THR as long as the THRE and TSRE bits are set in the LSR up to a specified limit (1024 is used here).

2013-01-17pty: return EINVAL for TIOCGPTN for BSD ptysJiri Slaby
Commit bbb63c514a3464342967237a51a21ea8f61ab951 (drivers:tty:fix up ENOIOCTLCMD error handling) changed the default return value from tty ioctl to be ENOTTY and not EINVAL. This is appropriate. But in case of TIOCGPTN for the old BSD ptys glibc started failing because it expects EINVAL to be returned. Only then it continues to obtain the pts name the other way around. So fix this case by explicit return of EINVAL in this case.

2013-01-17staging: vt6656: Fix inconsistent structure packingBen Hutchings
vt6656 has several headers that use the #pragma pack(1) directive to enable structure packing, but never disable it. The layout of structures defined in other headers can then depend on which order the various headers are included in, breaking the One Definition Rule. In practice this resulted in crashes on x86_64 until the order of header inclusion was changed for some files in commit 11d404cb56ecd ('staging: vt6656: fix headers and add cfg80211.'). But we need a proper fix that won't be affected by future changes to the order of inclusion. This removes the #pragma pack(1) directives and adds __packed to the structure definitions for which packing appears to have been intended.

John W. Linville says: ==================== This batch of fixes is intended for 3.8... Included is a Bluetooth pull. Gustavo says: "A few fixes for 3.8. Five of them are just new devices ids addition. Apart from the that there is fix to a kernel memory leak to userspace from Anderson Lizardo, two interoperability fixes from Jaganath Kanakkassery and Szymon Janc. And a crash fix by me." Along with that, Amitkumar Karwar brings a pair of mwifiex fixes for problems related to handling of band information within the driver. These problems can lead to association failures. Sujith Manoharan fixes a memory leak in the ath9k_htc code (originally reported by Larry Finger). The big hero this round is Felix Fietkau. Felix gives us seven ath9k fixes, including a fix for a race condition, the removal of a double-free, and a fix for a deadlock, among others. These have all been in linux-next for at least a couple of days, with no complaints so far. Please let me know if there are problems! ==================== Signed-off-by: David S.
