2012-12-02solos-pci: clean up pclose() functionDavid Woodhouse
- Flush pending TX skbs from the queue rather than waiting for them all to complete (suggested by Krzysztof Mazur <krzysiek@podlesie.net>). - Clear ATM_VF_ADDR only when the PKT_PCLOSE packet has been submitted. - Don't clear ATM_VF_READY at all — vcc_destroy_socket() does that for us.

2012-12-02solos-pci: wait for pending TX to complete when releasing vccDavid Woodhouse
We should no longer be calling the old pop routine for the vcc, after vcc_release() has completed. Make sure we wait for any pending TX skbs to complete, by waiting for our own PKT_PCLOSE control skb to be sent. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2012-11-26dsa: Hide core config options; make drivers select what they needBen Hutchings
Commit 82167cb8c6b2f8166d5c7532e5ef4b5e0cc46a72 ('net: dsa/slave: Fix compilation warnings') fixed one possible invalid configuration (NET_DSA enabled with no trailer formats) but added others: drivers can select NET_DSA without its dependencies being met. It's not very useful to make either the DSA core or the tagging formats manually selectable without a driver to use them, so: 1. Define a hidden HAVE_NET_DSA option and move the dependencies of NET_DSA to that. While we're at it, drop the deprecated EXPERIMENTAL dependency. 2. Make NET_DSA and the drivers dependent on HAVE_NET_DSA. 3. Hide the tagging format options again. 4. Make drivers select both NET_DSA and the appropriate tagging format option.

Currently when none of CONFIG_NET_DSA_TAG_DSA, CONFIG_NET_DSA_TAG_EDSA and CONFIG_NET_DSA_TAG_TRAILER is defined, we get following compilation warnings: net/dsa/slave.c:51:12: warning: 'dsa_slave_init' defined but not used [-Wunused-function] net/dsa/slave.c:60:12: warning: 'dsa_slave_open' defined but not used [-Wunused-function] net/dsa/slave.c:98:12: warning: 'dsa_slave_close' defined but not used [-Wunused-function] net/dsa/slave.c:116:13: warning: 'dsa_slave_change_rx_flags' defined but not used [-Wunused-function] net/dsa/slave.c:127:13: warning: 'dsa_slave_set_rx_mode' defined but not used [-Wunused-function] net/dsa/slave.c:136:12: warning: 'dsa_slave_set_mac_address' defined but not used [-Wunused-function] net/dsa/slave.c:164:12: warning: 'dsa_slave_ioctl' defined but not used [-Wunused-function] Earlier approach to fix this was discussed here: lkml.org/lkml/2012/10/29/549 This is another approach to fix it. This is done by some changes in config options, which make more sense than the earlier approach. As, atleast one tagging option must always be selected for using net/dsa/ infrastructure, this patch selects NET_DSA from tagging configs instead of having it as an selectable config.

2012-11-258139cp: set ring address after enabling C+ modeDavid Woodhouse
This fixes (for me) a regression introduced by commit b01af457 ("8139cp: set ring address before enabling receiver"). That commit configured the descriptor ring addresses earlier in the initialisation sequence, in order to avoid the possibility of triggering stray DMA before the correct address had been set up. Unfortunately, it seems that the hardware will scribble garbage into the TxRingAddr registers when we enable "plus mode" Tx in the CpCmd register. Observed on a Traverse Geos router board. To deal with this, while not reintroducing the problem which led to the original commit, we augment cp_start_hw() to write to the CpCmd register *first*, then set the descriptor ring addresses, and then finally to enable Rx and Tx in the original 8139 Cmd register. The datasheet actually indicates that we should enable Tx/Rx in the Cmd register *before* configuring the descriptor addresses, but that would appear to re-introduce the problem that the offending commit b01af457 was trying to solve. And this variant appears to work fine on real hardware. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Cc: stable@kernel.org [3.5+] Signed-off-by: David S. Miller <davem@davemloft.net>

I'd have recommitted that to make it somewhat cleaner, but figured by this point in the release cycle it was better to merge *exactly* the commits which have been in linux-next. If I'd recommitted, I'd also omit the sparse warning fix. But it's there, and it's harmless — just marking one function as 'static' in onenand code.

2012-11-23PM / QoS: fix wrong error-checking conditionGuennadi Liakhovetski
dev_pm_qos_add_request() can return 0, 1, or a negative error code, therefore the correct error test is "if (error < 0)." Checking just for non-zero return code leads to erroneous setting of the req->dev pointer to NULL, which then leads to a repeated call to dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn leads to an Oops, when the I2C host adapter is unloaded and reloaded again because of the inconsistent state of its QoS request list.

2012-11-23be2net: fix a possible events_get() race on BE2Sathya Perla
On BE2 chip, an interrupt being raised even when EQ is in un-armed state has been observed a few times. This is not expected and has never been observed on BE3/Lancer chips. As a consequence, be_msix()::events_get() and be_poll()::events_get() can race and notify an EQ wrongly causing a CEV UE. The other possible side-effect would be traffic stalling because after notifying EQ, napi_schedule() is ignored as NAPI is already running.

This might lead to various oopses, such as CPU 0 Pid: 6, comm: kworker/u:0 Not tainted 3.7.0-rc4 #1 Bochs Bochs RIP: 0010:[<ffffffff8134eef5>] [<ffffffff8134eef5>] blk_peek_request+0xd5/0x1c0 RSP: 0000:ffff88000dc7dd88 EFLAGS: 00010092 RAX: 0000000000000001 RBX: 0000000000000000 RCX: 0000000000000000 RDX: ffff88000f602688 RSI: ffffffff81fd95d8 RDI: 6b6b6b6b6b6b6b6b RBP: ffff88000dc7dd98 R08: ffffffff81fd95c8 R09: 0000000000000000 R10: ffffffff81fd9480 R11: 0000000000000001 R12: 6b6b6b6b6b6b6b6b R13: ffff88000dc7dfd8 R14: ffff88000dc7dfd8 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffffffff81e21000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000000000 CR3: 0000000001e11000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process kworker/u:0 (pid: 6, threadinfo ffff88000dc7c000, task ffff88000dc5ecc0) Stack: 0000000000000000 0000000000000000 ffff88000dc7ddb8 ffffffff8134efee ffff88000dc7ddb8 0000000000000000 ffff88000dc7dde8 ffffffff814aef3c ffffffff81e75d80 ffff88000dc0c640 ffff88000fbfb000 ffffffff814aed90 Call Trace: [<ffffffff8134efee>] blk_fetch_request+0xe/0x30 [<ffffffff814aef3c>] redo_fd_request+0x1ac/0x400 [<ffffffff814aed90>] ? start_motor+0x130/0x130 [<ffffffff8106b526>] process_one_work+0x136/0x450 [<ffffffff8106af65>] ? manage_workers+0x205/0x2e0 [<ffffffff8106bb6d>] worker_thread+0x14d/0x420 [<ffffffff8106ba20>] ? rescuer_thread+0x1a0/0x1a0 [<ffffffff8107075a>] kthread+0xba/0xc0 [<ffffffff810706a0>] ? __kthread_parkme+0x80/0x80 [<ffffffff818b553a>] ret_from_fork+0x7a/0xb0 [<ffffffff810706a0>] ? __kthread_parkme+0x80/0x80 Code: 0f 84 c0 00 00 00 83 f8 01 0f 85 e2 00 00 00 81 4b 40 00 00 80 00 48 89 df e8 58 f8 ff ff be fb ff ff ff fe ff ff <49> 8b 1c 24 49 39 dc 0f 85 2e ff ff ff 41 0f b6 84 24 28 04 00 RIP [<ffffffff8134eef5>] blk_peek_request+0xd5/0x1c0 RSP <ffff88000dc7dd88> Reported-by: Fengguang Wu <fengguang.wu@intel.com> Tested-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Jens Axboe <axboe@kernel.dk>

2012-11-22OMAPDSS: do not fail if dpll4_m4_ck is missingAaro Koskinen
Do not fail if dpll4_m4_ck is missing. The clock is not there on omap24xx, so this should not be a hard error. The patch retains the functionality before the commit 185bae10 (OMAPDSS: DSS: Cleanup cpu_is_xxxx checks).

2012-11-22igb: Do not parse past IP header on fragments beyond the firstAlexander Duyck
This change makes it so that only the first fragment in a series of fragments will have the L4 header pulled. Previously we were always pulling the L4 header as well and in the case of UDP this can harm performance since only the first fragment will have the header, the rest just contain data which should be left in the paged portion of the packet.

2012-11-22igb: No longer rely on APME to determine WoL settingsMatthew Vick
Historically, we've been using the APME bit to determine whether a device supports wake on a given port or not. However, this bit specifies the default wake setting, rather than the wake support. Change the behavior so that we use a flag to keep the capabilities separate from the enablement while meeting customer requirements.

2012-11-22ixgbe: fdb: only allow NUD_PERM fdb entriesJohn Fastabend
There was a bitwise operation error in the fdb_add block that was only allowing FDB types that were not permanent. This was the opposite of the intent because the hardware never ages out address these are the _only_ type of addrs that should be allowed. This was missed because until recently iproute2 did not set any bit for this by default. And our test code to manage FDB entries on embedded devices similarly did not set these bits. I am going to chalk this up as a bug and fix it now.
