4c67525 tcp: resets are misrouted After commit e2446eaa ("tcp_v4_send_reset: binding oif to iif in no sock case").. tcp resets are always lost, when routing is asymmetric. Yes, backing out that patch will result in misrouting of resets for dead connections which used interface binding when were alive, but we actually cannot do anything here. What's died that's died and correct handling normal unbound connections is obviously a priority. Comment to comment: > This has few benefits: > 1. tcp_v6_send_reset already did that. It was done to route resets for IPv6 link local addresses. It was a mistake to do so for global addresses. The patch fixes this as well. Actually, the problem appears to be even more serious than guaranteed loss of resets. As reported by Sergey Soloviev <sol@eqv.ru>, those misrouted resets create a lot of arp traffic and huge amount of unresolved arp entires putting down to knees NAT firewalls which use asymmetric routing.

8edc0e6 e1000e: Change wthresh to 1 to avoid possible Tx stalls This patch originated from Hiroaki SHIMODA but has been modified by Intel with some minor cleanups and additional commit log text. Denys Fedoryshchenko and others reported Tx stalls on e1000e with BQL enabled. Issue was root caused to hardware delays. They were introduced because some of the e1000e hardware with transmit writeback bursting enabled, waits until the driver does an explict flush OR there are WTHRESH descriptors to write back. Sometimes the delays in question were on the order of seconds, causing visible lag for ssh sessions and unacceptable tx completion latency, especially for BQL enabled kernels. To avoid possible Tx stalls, change WTHRESH back to 1. The current plan is to investigate a method for re-enabling WTHRESH while not harming BQL, but those patches will be later for net-next if they work. please enqueue for stable since v3.3 as this bug was introduced in commit 3f0cfa3bc11e7f00c9994e0f469cbc0e7da7b00c Author: Tom Herbert <therbert@google.com> Date: Mon Nov 28 16:33:16 2011 +0000 e1000e: Support for byte queue limits Changes to e1000e to use byte queue limits.

5aa8b57 pktgen: fix crash when generating IPv6 packets For IPv6, sizeof(struct ipv6hdr) = 40, thus the following expression will result negative: datalen = pkt_dev->cur_pkt_size - 14 - sizeof(struct ipv6hdr) - sizeof(struct udphdr) - pkt_dev->pkt_overhead; And, the check "if (datalen < sizeof(struct pktgen_hdr))" will be passed as "datalen" is promoted to unsigned, therefore will cause a crash later. This is a quick fix by checking if "datalen" is negative. The following patch will increase the default value of 'min_pkt_size' for IPv6. This bug should exist for a long time, so Cc -stable too.

2474542 Merge tag 'for-3.7-rc1' of git://gitorious.org/linux-pwm/linux-pwm Pull pwm changes from Thierry Reding: "All legacy PWM providers have now been moved to the PWM subsystem. The plan for 3.8 is to adapt all board files to provide a lookup table for PWM devices in order to get rid of the global namespace. Subsequently, users of the legacy pwm_request() and pwm_free() functions can be migrated to the new pwm_get() and pwm_put() functions. Once this has been completed, the legacy API and the compatibility code in the core can be removed. In addition to the above, these changes also add support for configuring the polarity of a PWM signal (currently only supported on ECAP and EHRPWM) and include a much needed rework of the i.MX driver. Managed functions to obtain and release a PWM device (devm_pwm_get() and devm_pwm_put()) have been added and the pwm-backlight driver has been updated to use them. If the PWM subsystem hasn't been enabled, dummy functions are provided that allow the subsystem to safely compile out. Some common checks on input parameters have been moved to the core and removed from the drivers. Finally, a small fix corrects the description of the PWM specifier's second cell in the device tree representation." * tag 'for-3.7-rc1' of git://gitorious.org/linux-pwm/linux-pwm: (23 commits) pwm: dt: Fix description of second PWM cell pwm: Check for negative duty-cycle and period pwm: Add Ingenic JZ4740 support MIPS: JZ4740: Export timer API pwm: Move PUV3 PWM driver to PWM framework unicore32: pwm: Use managed resource allocations unicore32: pwm: Remove unnecessary indirection unicore32: pwm: Use module_platform_driver() unicore32: pwm: Properly remap memory-mapped registers pwm-backlight: Use devm_pwm_get() instead of pwm_get() pwm: Move AB8500 PWM driver to PWM framework pwm: Fix compilation error when CONFIG_PWM is not defined pwm: i.MX: fix clock lookup pwm: i.MX: use per clock unconditionally pwm: i.MX: add devicetree support pwm: i.MX: Use module_platform_driver pwm: i.MX: add functions to enable/disable pwm. pwm: i.MX: remove unnecessary if in pwm_[en|dis]able pwm: i.MX: factor out SoC specific functions pwm: pwm-tiehrpwm: Add support for configuring polarity of PWM ... 10 October 2012, 11:15:24 UTC

Fix from Gao Feng. 3) Now that tunnels support GRO, we have to be more careful in skb_gro_reset_offset() otherwise we OOPS, from Eric Dumazet. 4) We can end up processing packets for VLANs we aren't actually configured to be on, fix from Florian Zumbiehl. 5) Fix routing cache removal regression in redirects and IPVS. The core issue on the IPVS side is that it wants to rewrite who the nexthop is and we have to explicitly accomodate that case. From Julian Anastasov. 6) Error code return fixes all over the networking drivers from Peter Senna Tschudin. 7) Fix routing cache removal regressions in IPSEC, from Steffen Klassert. 8) Fix deadlock in RDS during pings, from Jeff Liu. 9) Neighbour packet queue can trigger skb_under_panic() because we do not reset the network header of the SKB in the right spot.

5175a5e RDS: fix rds-ping spinlock recursion This is the revised patch for fixing rds-ping spinlock recursion according to Venkat's suggestions. RDS ping/pong over TCP feature has been broken for years(2.6.39 to 3.6.0) since we have to set TCP cork and call kernel_sendmsg() between ping/pong which both need to lock "struct sock *sk". However, this lock has already been hold before rds_tcp_data_ready() callback is triggerred. As a result, we always facing spinlock resursion which would resulting in system panic. Given that RDS ping is only used to test the connectivity and not for serious performance measurements, we can queue the pong transmit to rds_wq as a delayed response.

0f79657 pch_gbe: Fix build error by selecting all the possible dependencies. Fengguang reported a kernel build failure as following: drivers/built-in.o: In function `pch_gbe_ioctl': pch_gbe_main.c:(.text+0x510370): undefined reference to `pch_ch_control_write' pch_gbe_main.c:(.text+0x510393): undefined reference to `pch_ch_control_write' pch_gbe_main.c:(.text+0x5103b3): undefined reference to `pch_ch_control_write' ... It's a regression by commit da1586461. The root cause is that the CONFIG_PPS is not set there, consequently CONFIG_PTP_1588_CLOCK can not be set anyway, which finally causes ptp_pch and pch_gbe_main build failures. As David prefers to use *select* to fix such module co-dependency issues, this patch explicitly selects all the possible dependencies of PCH_PTP.

5af3e8c Btrfs: make filesystem read-only when submitting barrier fails So far the return code of barrier_all_devices() is ignored, which means that errors are ignored. The result can be a corrupt filesystem which is not consistent. This commit adds code to evaluate the return code of barrier_all_devices(). The normal btrfs_error() mechanism is used to switch the filesystem into read-only mode when errors are detected. In order to decide whether barrier_all_devices() should return error or success, the number of disks that are allowed to fail the barrier submission is calculated. This calculation accounts for the worst RAID level of metadata, system and data. If single, dup or RAID0 is in use, a single disk error is already considered to be fatal. Otherwise a single disk error is tolerated. The calculation of the number of disks that are tolerated to fail the barrier operation is performed when the filesystem gets mounted, when a balance operation is started and finished, and when devices are added or removed.

e613887 Btrfs: cache extent state when writing out dirty metadata pages Everytime we write out dirty pages we search for an offset in the tree, convert the bits in the state, and then when we wait we search for the offset again and clear the bits. So for every dirty range in the io tree we are doing 4 rb searches, which is suboptimal. With this patch we are only doing 2 searches for every cycle (modulo weird things happening).

ce19533 Btrfs: do not hold the file extent leaf locked when adding extent item For some reason we unlock everything except the leaf we are on, set the path blocking and then add the extent item for the extent we just finished writing. I can't for the life of me figure out why we would want to do this, and the history doesn't really indicate that there was a real reason for it, so just remove it. This will reduce our tree lock contention on heavy writes. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com> 09 October 2012, 13:15:40 UTC
de0022b Btrfs: do not async metadata csumming in certain situations There are a coule scenarios where farming metadata csumming off to an async thread doesn't help. The first is if our processor supports crc32c, in which case the csumming will be fast and so the overhead of the async model is not worth the cost. The other case is for our tree log. We will be making that stuff dirty and writing it out and waiting for it immediately. Even with software crc32c this gives me a ~15% increase in speed with O_SYNC workloads.

221b831 btrfs: fix min csum item size warnings in 32bit commit 7ca4be45a0255ac8f08c05491c6add2dd87dd4f8 limited csum items to PAGE_CACHE_SIZE. It used min() with incompatible types in 32bit which generates warnings: fs/btrfs/file-item.c: In function ‘btrfs_csum_file_blocks’: fs/btrfs/file-item.c:717: warning: comparison of distinct pointer types lacks a cast This uses min_t(u32,) to fix the warnings. u32 seemed reasonable because btrfs_root->leafsize is u32 and PAGE_CACHE_SIZE is unsigned long.

354aa0f Btrfs: fix orphan transaction on the freezed filesystem With the following debug patch: static int btrfs_freeze(struct super_block *sb) { + struct btrfs_fs_info *fs_info = btrfs_sb(sb); + struct btrfs_transaction *trans; + + spin_lock(&fs_info->trans_lock); + trans = fs_info->running_transaction; + if (trans) { + printk("Transid %llu, use_count %d, num_writer %d\n", + trans->transid, atomic_read(&trans->use_count), + atomic_read(&trans->num_writers)); + } + spin_unlock(&fs_info->trans_lock); return 0; } I found there was a orphan transaction after the freeze operation was done. It is because the transaction may not be committed when the transaction handle end even though it is the last handle of the current transaction. This design avoid committing the transaction frequently, but also introduce the above problem. So I add btrfs_attach_transaction() which can catch the current transaction and commit it. If there is no transaction, it will return ENOENT, and do not anything. This function also can be used to instead of btrfs_join_transaction_freeze() because it don't increase the writer counter and don't start a new transaction, so it also can fix the deadlock between sync and freeze. Besides that, it is used to instead of btrfs_join_transaction() in transaction_kthread(), because if there is no transaction, the transaction kthread needn't anything.

d24bec3 btrfs: extended inode ref iteration The iterate_irefs in backref.c is used to build path components from inode refs. This patch adds code to iterate extended refs as well. I had modify the callback function signature to abstract out some of the differences between ref structures. iref_to_path() also needed similar changes.

450e47d s390/entry: fix svc number for TIF_SYSCALL system call restart The load of the svc number in the TIF_SYSCALL restart path needs to be done with an instruction that loads all 64 bits of %r1, 'lh' only loads 32 bits. If the upper half of %r1 is not zero and has the msb set, entry64.S will try to execute an svc with a really large number. What will be in the upper half of %r1 depends on the code generated by gcc for the functions on the do_signal() callchain.

This allows to always have a large frame in the identity mapping of the kernel image for beginning of the text section, if the machine has EDAT1 support.
