2013-08-20writeback: fix NULL dereference when device is goneblockdevPeter Wu1-1/+2
This solves a BUG followed by a lockup in the following case: 1. Connect device and look in dmesg for the address: [ 40.034520] usb 6-2: Product: My Passport 0748 2. Write something: dd if=/dev/zero of=/dev/sdd bs=1M 3. Remove device: echo 1 > /sys/bus/usb/devices/6-2/remove 4. Machine locks up (because the work queue got stuck?).

2013-08-19proc: return on proc_readdir errorRichard Genoud1-1/+3
Commit f0c3b5093add ("[readdir] convert procfs") introduced a bug on the listing of the proc file-system. The return value of proc_readdir() isn't tested anymore in the proc_root_readdir function. This lead to an "interesting" behaviour when we are using the getdents() system call with a buffer too small: instead of failing, it returns the first entries of /proc (enough to fill the given buffer), plus the PID directories. This is not triggered on glibc (as getdents is called with a 32KB buffer), but on uclibc, the buffer size is only 1KB, thus some proc entries are missing. See https://lkml.org/lkml/2013/8/12/288 for more background.

2013-08-19GFS2: don't overrun reserved revokesBenjamin Marzinski1-5/+13
When run during fsync, a gfs2_log_flush could happen between the time when gfs2_ail_flush checked the number of blocks to revoke, and when it actually started the transaction to do those revokes. This occassionally caused it to need more revokes than it reserved, causing gfs2 to crash. Instead of just reserving enough revokes to handle the blocks that currently need them, this patch makes gfs2_ail_flush reserve the maximum number of revokes it can, without increasing the total number of reserved log blocks. This patch also passes the number of reserved revokes to __gfs2_ail_flush() so that it doesn't go over its limit and cause a crash like we're seeing. Non-fsync calls to __gfs2_ail_flush will still cause a BUG() necessary revokes are skipped.

This fixes a WARN in i915_gem_free_object when the obj->pages_pin_count isn't 0. v2: Add locking to unmap, noticed by Chris Wilson. Note that even though we call unmap with our own dev->struct_mutex held that won't result in an immediate deadlock since we never go through the dma_buf interfaces for our own, reimported buffers. But it's still easy to blow up and anger lockdep, but that's already the case with our ->map implementation. Fixing this for real will involve per dma-buf ww mutex locking by the callers. And lots of fun. So go with the duct-tape approach for now.

Commit 0713ed0cde76438d05849f1537d3aab46e099475 added jbd2_journal_file_inode() call into ext4_block_zero_page_range(). However that function gets called from truncate path and thus inode needn't have jinode attached - that happens in ext4_file_open() but the file needn't be ever open since mount. Calling jbd2_journal_file_inode() without jinode attached results in the oops. We fix the problem by attaching jinode to inode also in ext4_truncate() and ext4_punch_hole() when we are going to zero out partial blocks.

2013-08-16Fix TLB gather virtual address range invalidation corner casesLinus Torvalds11-34/+57
Ben Tebulin reported: "Since v3.7.2 on two independent machines a very specific Git repository fails in 9/10 cases on git-fsck due to an SHA1/memory failures. This only occurs on a very specific repository and can be reproduced stably on two independent laptops. Git mailing list ran out of ideas and for me this looks like some very exotic kernel issue" and bisected the failure to the backport of commit 53a59fc67f97 ("mm: limit mmu_gather batching to fix soft lockups on !CONFIG_PREEMPT"). That commit itself is not actually buggy, but what it does is to make it much more likely to hit the partial TLB invalidation case, since it introduces a new case in tlb_next_batch() that previously only ever happened when running out of memory. The real bug is that the TLB gather virtual memory range setup is subtly buggered. It was introduced in commit 597e1c3580b7 ("mm/mmu_gather: enable tlb flush range in generic mmu_gather"), and the range handling was already fixed at least once in commit e6c495a96ce0 ("mm: fix the TLB range flushed when __tlb_remove_page() runs out of slots"), but that fix was not complete. The problem with the TLB gather virtual address range is that it isn't set up by the initial tlb_gather_mmu() initialization (which didn't get the TLB range information), but it is set up ad-hoc later by the functions that actually flush the TLB. And so any such case that forgot to update the TLB range entries would potentially miss TLB invalidates. Rather than try to figure out exactly which particular ad-hoc range setup was missing (I personally suspect it's the hugetlb case in zap_huge_pmd(), which didn't have the same logic as zap_pte_range() did), this patch just gets rid of the problem at the source: make the TLB range information available to tlb_gather_mmu(), and initialize it when initializing all the other tlb gather fields. This makes the patch larger, but conceptually much simpler. And the end result is much more understandable; even if you want to play games with partial ranges when invalidating the TLB contents in chunks, now the range information is always there, and anybody who doesn't want to bother with it won't introduce subtle bugs. Ben verified that this fixes his problem.

2013-08-15net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changesMoshe Lazer6-49/+41
In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.

2013-08-15net: tg3: fix NULL pointer dereference in tg3_io_error_detected and ↵Daniel Borkmann1-5/+8
tg3_io_slot_reset Commit d8af4dfd8 ("net/tg3: Fix kernel crash") introduced a possible NULL pointer dereference in tg3 driver when !netdev || !netif_running(netdev) condition is met and netdev is NULL. Then, the jump to the 'done' label calls dev_close() with a netdevice that is NULL. Therefore, only call dev_close() when we have a netdevice, but one that is not running.

2013-08-15ASoC: tegra: fix Tegra30 I2S capture parameter setupStephen Warren1-1/+1
The Tegra30 I2S driver was writing the AHUB interface parameters to the playback path register rather than the capture path register. This caused the capture parameters not to be configured at all, so if capturing using non-HW-default parameters (e.g. 16-bit stereo rather than 8-bit mono) the audio would be corrupted. With this fixed, audio capture from an analog microphone works correctly on the Cardhu board.

2013-08-15net_sched: restore "linklayer atm" handlingJesper Dangaard Brouer5-2/+72
commit 56b765b79 ("htb: improved accuracy at high rates") broke the "linklayer atm" handling. tc class add ... htb rate X ceil Y linklayer atm The linklayer setting is implemented by modifying the rate table which is send to the kernel. No direct parameter were transferred to the kernel indicating the linklayer setting. The commit 56b765b79 ("htb: improved accuracy at high rates") removed the use of the rate table system. To keep compatible with older iproute2 utils, this patch detects the linklayer by parsing the rate table. It also supports future versions of iproute2 to send this linklayer parameter to the kernel directly. This is done by using the __reserved field in struct tc_ratespec, to convey the choosen linklayer option, but only using the lower 4 bits of this field. Linklayer detection is limited to speeds below 100Mbit/s, because at high rates the rtab is gets too inaccurate, so bad that several fields contain the same values, this resembling the ATM detect. Fields even start to contain "0" time to send, e.g. at 1000Mbit/s sending a 96 bytes packet cost "0", thus the rtab have been more broken than we first realized.

This reverts commit f83331bab149e29fa2c49cf102c0cd8c3f1ce9f9. As the tests PPC64 (powernv platform) show, IOMMU pages are leaking when transferring big amount of small packets (<=64 bytes), "ping -f" and waiting for 15 seconds is the simplest way to confirm the bug.

2013-08-14openvswitch: Reset tunnel key between input and output.Jesse Gross1-0/+1
It doesn't make sense to output a tunnel packet using the same parameters that it was received with since that will generally just result in the packet going back to us. As a result, userspace assumes that the tunnel key is cleared when transitioning through the switch. In the majority of cases this doesn't matter since a packet is either going to a tunnel port (in which the key is overwritten with new values) or to a non-tunnel port (in which case the key is ignored). However, it's theoreticaly possible that userspace could rely on the documented behavior, so this corrects it. Signed-off-by: Jesse Gross <jesse@nicira.com>
