With the support to bounce buffer added, the skb is coming as nonlinear in the case of non-DDPed data frames for FCoE, which is mostly ok as the FCoE stack would take care of that. However, for target mode, we have to set the FC CRC and FC EOF field to allow the protocol stack to not drop the frame for the last data frame of that sequence. So fix this by linearizing the skb first before doing skb_put(). Signed-off-by:

The driver was freeing memory in shutdown instead of remove. As a result we were leaking memory if IEEE DCB was enabled and we loaded/unloaded the driver. This change moves the freeing of the memory into the remove routine where it belongs. Signed-off-by:

When the cwnd reduction is done, ssthresh may be infinite if TCP enters CWR via ECN or F-RTO. If cwnd is not undone, i.e., undo_marker is set, tcp_complete_cwr() falsely set cwnd to the infinite ssthresh value. The correct operation is to keep cwnd intact because it has been updated in ECN or F-RTO. Signed-off-by:

Now the helper function from filter.c for negative offsets is exported, it can be used it in the jit to handle negative offsets. First modify the asm load helper functions to handle: - know positive offsets - know negative offsets - any offset then the compiler can be modified to explicitly use these helper when appropriate. This fixes the case of a negative X register and allows to lift the restriction that bpf programs with negative offsets can't be jited. Tested-by:

Eric Dumazet pointed out to me that the drop_monitor protocol has some holes in its smp protections. Specifically, its possible to replace data->skb while its being written. This patch corrects that by making data->skb an rcu protected variable. That will prevent it from being overwritten while a tracepoint is modifying it. Signed-off-by:

Since we only use the trace_state_lock to prevent trace protocol state races, as well as hardware stat list updates on an rcu write side, we can just convert the spinlock to a mutex to avoid this problem.

Clean up a reference to jiffies in tcp_rcv_rtt_measure() that should instead reference tcp_time_stamp. Since the result of the subtraction is passed into a function taking u32, this should not change any behavior (and indeed the generated assembly does not change on x86_64). However, it seems worth cleaning this up for consistency and clarity (and perhaps to avoid bugs if this is copied and pasted somewhere else). Signed-off-by:

The dl2k driver's rio_ioctl call has a few issues: - No permissions checking - Implements SIOCGMIIREG and SIOCGMIIREG using the SIOCDEVPRIVATE numbers - Has a few ioctls that may have been used for debugging at one point but have no place in the kernel proper. This patch removes all but the MII ioctls, renumbers them to use the standard ones, and adds the proper permission check for SIOCSMIIREG. We can also get rid of the dl2k-specific struct mii_data in favor of the generic struct mii_ioctl_data. Since we have the phyid on hand, we can add the SIOCGMIIPHY ioctl too. Most of the MII code for the driver could probably be converted to use the generic MII library but I don't have a device to test the results. Reported-by:

commit a4910b74 has broken promiscuous mode, which is never set. port->promisc just reflects the last setting of PROMISCUOUS mode to avoid doing an extra hypercall when it's already set.

There was a bug in the mask of regtype parameter for registering a multicast filter. It was ignoring the scope bit, which was wrongly being used for all filters. The SCOPE_ALL value adds a filter that allows all multicast packets and ignores the MAC parameter, just what allmulticast needs. The normals filters, however, should not use SCOPE_ALL. Signed-off-by:

The registration of a protocol might fail, there were no checks and all registrations were assumed to be correct. This lead to NULL ptr dereferences when apps tried registering. For example: [ 1293.226051] BUG: unable to handle kernel NULL pointer dereference at 0000000000000018 [ 1293.227038] IP: [<ffffffff822aacb0>] tcp_register_app+0x60/0xb0 [ 1293.227038] PGD 391de067 PUD 6c20b067 PMD 0 [ 1293.227038] Oops: 0000 [#1] PREEMPT SMP [ 1293.227038] CPU 1 [ 1293.227038] Pid: 19609, comm: trinity Tainted: G W 3.4.0-rc1-next-20120405-sasha-dirty #57 [ 1293.227038] RIP: 0010:[<ffffffff822aacb0>] [<ffffffff822aacb0>] tcp_register_app+0x60/0xb0 [ 1293.227038] RSP: 0018:ffff880038c1dd18 EFLAGS: 00010286 [ 1293.227038] RAX: ffffffffffffffc0 RBX: 0000000000001500 RCX: 0000000000010000 [ 1293.227038] RDX: 0000000000000000 RSI: ffff88003a2d5888 RDI: 0000000000000282 [ 1293.227038] RBP: ffff880038c1dd48 R08: 0000000000000000 R09: 0000000000000000 [ 1293.227038] R10: 0000000000000000 R11: 0000000000000000 R12: ffff88003a2d5668 [ 1293.227038] R13: ffff88003a2d5988 R14: ffff8800696a8ff8 R15: 0000000000000000 [ 1293.227038] FS: 00007f01930d9700(0000) GS:ffff88007ce00000(0000) knlGS:0000000000000000 [ 1293.227038] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b [ 1293.227038] CR2: 0000000000000018 CR3: 0000000065dfc000 CR4: 00000000000406e0 [ 1293.227038] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 1293.227038] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 1293.227038] Process trinity (pid: 19609, threadinfo ffff880038c1c000, task ffff88002dc73000) [ 1293.227038] Stack: [ 1293.227038] ffff880038c1dd48 00000000fffffff4 ffff8800696aada0 ffff8800694f5580 [ 1293.227038] ffffffff8369f1e0 0000000000001500 ffff880038c1dd98 ffffffff822a716b [ 1293.227038] 0000000000000000 ffff8800696a8ff8 0000000000000015 ffff8800694f5580 [ 1293.227038] Call Trace: [ 1293.227038] [<ffffffff822a716b>] ip_vs_app_inc_new+0xdb/0x180 [ 1293.227038] [<ffffffff822a7258>] register_ip_vs_app_inc+0x48/0x70 [ 1293.227038] [<ffffffff822b2fea>] __ip_vs_ftp_init+0xba/0x140 [ 1293.227038] [<ffffffff821c9060>] ops_init+0x80/0x90 [ 1293.227038] [<ffffffff821c90cb>] setup_net+0x5b/0xe0 [ 1293.227038] [<ffffffff821c9416>] copy_net_ns+0x76/0x100 [ 1293.227038] [<ffffffff810dc92b>] create_new_namespaces+0xfb/0x190 [ 1293.227038] [<ffffffff810dca21>] unshare_nsproxy_namespaces+0x61/0x80 [ 1293.227038] [<ffffffff810afd1f>] sys_unshare+0xff/0x290 [ 1293.227038] [<ffffffff8187622e>] ? trace_hardirqs_on_thunk+0x3a/0x3f [ 1293.227038] [<ffffffff82665539>] system_call_fastpath+0x16/0x1b [ 1293.227038] Code: 89 c7 e8 34 91 3b 00 89 de 66 c1 ee 04 31 de 83 e6 0f 48 83 c6 22 48 c1 e6 04 4a 8b 14 26 49 8d 34 34 48 8d 42 c0 48 39 d6 74 13 <66> 39 58 58 74 22 48 8b 48 40 48 8d 41 c0 48 39 ce 75 ed 49 8d [ 1293.227038] RIP [<ffffffff822aacb0>] tcp_register_app+0x60/0xb0 [ 1293.227038] RSP <ffff880038c1dd18> [ 1293.227038] CR2: 0000000000000018 [ 1293.379284] ---[ end trace 364ab40c7011a009 ]--- [ 1293.381182] Kernel panic - not syncing: Fatal exception in interrupt Signed-off-by:
