* fs: Fix imbalance in freeze protection in mark_files_ro()Jan Kara2012-12-201-1/+1
| | | | | | | | | | | | | | | | | | | File descriptors (even those for writing) do not hold freeze protection. Thus mark_files_ro() must call __mnt_drop_write() to only drop protection against remount read-only. Calling mnt_drop_write_file() as we do now results in: [ BUG: bad unlock balance detected! ] 3.7.0-rc6-00028-g88e75b6 #101 Not tainted ------------------------------------- kworker/1:2/79 is trying to release lock (sb_writers) at: [<ffffffff811b33b4>] mnt_drop_write+0x24/0x30 but there are no more locks to release!

| | | | | | | | | | | The code that relied on that flag was ripped out of btrfs quite some time ago, and never added back.

* vfs: remove unneeded permission check from path_initJeff Layton2012-12-201-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | When path_init is called with a valid dfd, that code checks permissions on the open directory fd and returns an error if the check fails. This permission check is redundant, however. Both callers of path_init immediately call link_path_walk afterward. The first thing that link_path_walk does for pathnames that do not consist only of slashes is to check for exec permissions at the starting point of the path walk. And this check in path_init() is on the path taken only when *name != '/' && *name != '\0'. In most cases, these checks are very quick, but when the dfd is for a file on a NFS mount with the actimeo=0, each permission check goes out onto the wire. The result is 2 identical ACCESS calls. Given that these codepaths are fairly "hot", I think it makes sense to eliminate the permission check in path_init and simply assume that the caller will eventually check the permissions before proceeding.

| * sparc64: Fix AES ctr mode block size.David S. Miller2012-12-191-3/+24
| | | | | | | | | | | | | | | | | | | | Like the generic versions, we need to support a block size of '1' for CTR mode AES. This was discovered thanks to all of the new test cases added by Jussi Kivilinna. Signed-off-by: David S. Miller <davem@davemloft.net>
| * sparc64: Fix unrolled AES 256-bit key loops.David S. Miller2012-12-191-6/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic scheme of the block mode assembler is that we start by enabling the FPU, loading the key into the floating point registers, then iterate calling the encrypt/decrypt routine for each block. For the 256-bit key cases, we run short on registers in the unrolled loops. So the {ENCRYPT,DECRYPT}_256_2() macros reload the key registers that get clobbered. The unrolled macros, {ENCRYPT,DECRYPT}_256(), are not mindful of this. So if we have a mix of multi-block and single-block calls, the single-block unrolled 256-bit encrypt/decrypt can run with some of the key registers clobbered. Handle this by always explicitly loading those registers before using the non-unrolled 256-bit macro. This was discovered thanks to all of the new test cases added by Jussi Kivilinna.

As a result of this, the ksz884x receive path ends up locking up fairly easily, when the receive processing tasklet's reenabling of receive interrupts (due to it being done with polling the receive ring) races with the interrupt handler's disabling of receive interrupts (due to a new receive interrupt coming in) resulting in the receive interrupt being masked but the receive processing tasklet not being scheduled. Fix this by making the ksz884x interrupt handler take its private interface spinlock. This requires upgrading the spin_lock() in the transmit cleanup tasklet to a spin_lock_irq(), as otherwise the IRQ handler can preempt transmit cleanup and deadlock the system, but with those two changes, no more receive lockups have been observed.

However the rt2x00 driver stores driver specific data in the cb array of the rx skbs, so the fields might contain garbage and this can cause unexpected behaviour. The rt2x00 driver from the compat-wireless-2012-12-01 tarball caused the following warning: WARNING: at /devel/ramips/build_dir/target-mipsel_r2_uClibc-0.9.33.2/linux-ramips_rt305x/ compat-wireless-2012-12-01/net/mac80211/rx.c:115 ieee80211_rx_irqsafe+0x274/0xbcc [mac80211]() Modules linked in: dwc_otg ledtrig_usbdev nf_nat_irc nf_nat_ftp nf_conntrack_irc nf_conntrack_ftp ipt_MASQUERADE iptable_nat nf_nat pppoe xt_conntrack xt_CT xt_NOTRACK iptable_raw xt_state nf_conntrack_ipv4 nf_defrag_ipv4 nf_conntrack pppox ipt_REJECT xt_TCPMSS xt_comment xt_multiport xt_mac xt_limit iptable_mangle iptable_filter ip_tables xt_tcpudp x_tables ppp_async ppp_generic slhc rt2800pci(O) rt2800lib(O) rt2x00soc(O) rt2x00pci(O) rt2x00lib(O) mac80211(O) usbcore usb_common nls_base crc_itu_t crc_ccitt eeprom_93cx6 cfg80211(O) compat(O) arc4 aes_generic crypto_blkcipher cryptomgr aead crypto_hash crypto_algapi leds_gpio button_hotplug(O) gpio_keys_polled input_polldev input_core Call Trace: [<801e96b4>] dump_stack+0x8/0x34 [<80010a9c>] warn_slowpath_common+0x78/0xa4 [<80010ae0>] warn_slowpath_null+0x18/0x24 [<80a9710c>] ieee80211_rx_irqsafe+0x274/0xbcc [mac80211] The patch ensures that each field gets initialized with zeroes.

| * | | net: fec: forbid FEC_PTP on SoCs that do not supportShawn Guo2012-12-181-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Beside imx6q, the kernel built from imx_v6_v7_defconfig is also supposed to be running on other IMX SoCs that do not have the PTP block. Before fec driver gets fixed to run-time detect target hardware rather than conditional compiling with #ifdef CONFIG_FEC_PTP, let's give it a quick fix in Kconfig to forbid FEC_PTP on those IMX SoCs that do not support PTP.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RX CQ can report completions with invalid frag_idx when the RXQ that was *previously* using it, was not cleaned up properly. This hits a BUG_ON() in be2net. When completion coalescing is enabled on a CQ, an explicit CQ-notify (with rearm) is needed for each compl, to flush partially coalesced CQ entries that are pending DMA. In be_close(), this fix now notifies CQ for each compl, waits explicitly for the flush compl to arrive and complains if it doesn't arrive. Also renaming be_crit_error() to be_hw_error() as it's the more appropriate name and to convey that we don't wait for the flush compl only when a HW error has occurred.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In be_close(), be_eq_clean() must be called after all RX/TX/MCC queues have been cleaned to ensure that any events caused while cleaning up completions are notified/acked. Not clearing all events can cause upredictable behaviour when RX rings are re-created in the subsequent be_open(). Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.
