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.

11 years agoFix TLB gather virtual address range invalidation corner cases
Linus Torvalds [Thu, 15 Aug 2013 18:42:25 +0000 (11:42 -0700)]
Fix TLB gather virtual address range invalidation corner cases

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.

In the previous QUERY_PAGES command version we used one command to get 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

net_sched: restore "linklayer atm" handling

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.

Let's start with a little history:

Feb 20:   Vlad Yasevich got his VLAN-aware bridge patchset included in
          the 3.9 merge window.
          In the kernel commit 6cbdceeb, he added attribute support to

Mar 6th:  Vlad got this iproute2 reference implementation of the bridge
          vlan netlink interface accepted (iproute2 9eff0e5c)

Apr 25th: iproute2 switched from using rtgenmsg to ifinfomsg (63338dca)
          http://patchwork.ozlabs.org/patch/239602/
          http://marc.info/?t=136680900700007

Apr 28th: Linus released 3.9

Apr 30th: Stephen released iproute2 3.9.0

The `bridge vlan show` command haven't been working since the switch to
ifinfomsg, or in a released version of iproute2. Since the kernel side
only supports rtgenmsg, which iproute2 switched away from just prior to
the iproute2 3.9.0 release.

I haven't been able to find any documentation, about neither rtgenmsg
nor ifinfomsg, and in which situation to use which, but kernel commit
88c5b5ce seams to suggest that ifinfomsg should be used.

Fixing this in kernel will break compatibility, but I doubt that anybody
have been using it due to this bug in the user space reference
implementation, at least not without noticing this bug. That said the
functionality is still fully functional in 3.9, when reversing iproute2
commit 63338dca.

This could also be fixed in iproute2, but thats an ugly patch that would
reintroduce rtgenmsg in iproute2, and from searching in netdev it seams
like rtgenmsg usage is discouraged. I'm assuming that the only reason
that Vlad implemented the kernel side to use rtgenmsg, was because
iproute2 was using it at the time.
