Re: [uml-user] [info] syscalls mmap and mremap no longer fails w/SLUB

Good to hear. MM folks fixed a off-by-one error a few days ago.
Maybe you ran into that problem...

Thanks,

[uml-user] [info] syscalls mmap and mremap no longer fails w/ SLUB

Toralf Förster — 2013-05-07T17:19:59

Since today both syscalls seems to work fine with SLUB and guest kernel
linux-v3.9-10998-g1b9b170 at a stable Getnoo 32 bit, now just these 4
are still forcing kernel bugs if stressed with trinity :

-x mount -x request_key -x add_key -x keyctl

(me just re-tested both b/c I saw a lot af SLAB/SLUB related merges into
mainline but ofc I'm unsure when those 2 were fixed).

[uml-user] BUG: spinlock recursion 3.9.0-10520-gf8cf7ba

Toralf Förster — 2013-05-06T20:47:04

The following BUG was triggered by trinity on an UML guest with kernel
version 3.9.0-10520-gf8cf7ba and host kernel 3.9, both are stable 32 bit Gentoo Linux.

Is this UML specific or worth to be reported to LKML too ?

[uml-user] fuzzying UML with SLAB gives sometimes a page allocationfailure

Toralf Förster — 2013-04-30T20:22:33

While playing with kernel 3.9 (host) and current git kernel linux-v3.9-3618-g490b364 (guest)
and running trinity on the guest I got after a longer run of trinity
syslog messages at the guest as seen below.

I get these only if I compiled the UML guest kernel with SLAB (and not with SLUB).
But b/c under SLUB I cannot test the 6 syscalls mremap, mmap, mount, add_key, request_key and keyctl
(those are known to fail immediately and tainting the guest kernel) I've no clue whether the page
allocation failure is related to those syscalls or to SLAB itself.

I'll run trinity excluding those 6 syscalls but that needs time.

Both host and guest are 32 bit stable Gentoo, the victim files + directories for trinity
are located on a directory mounted on the guest via hostfs and nfsv4 respectively.

no, already tried, but both commands don't show ip addresses of the TAP
device

$ ip addr show tap0

Re: [uml-user] derive assigned DHCP address of a tap device

Tony Su — 2013-04-26T22:18:18

Don't know what you might mean by derive, getting info on the Guest,
Host or DHCP server.

If on the Guest or Host, will any of the following answer your question?

ip addr
ifconfig

[uml-user] derive assigned DHCP address of a tap device

Toralf Förster — 2013-04-26T16:26:28

After I started an UML instance (configured to get a DHCP address from
the host where dnsmasq acts as a DHCP server) I'd later like to derive
which ip address the appropriate TAP device was assigned too.

Currently I'm at a loss how to do this.

[uml-user] trinity triggers (a different ?) madvise syscall issue: "BUG: Bad page map" and "BUG: Bad rss-counter"

and 3.8.7 host kernel (both 32 bit Gentoo Linux) can repeatable be triggered:

[uml-user] uml + SLAB + trinity triggers: WARNING: atmm/mmap.c:2702 exit_mmap+0x161/0x170()

Toralf Förster — 2013-04-11T18:46:59

Just for completeness, if SLAB is chosen (SLUB issues are already reported)
then with host kernel 3.8.6 and guest kernel 3.9-rc6-xxx and 32bit stable Gentoo Linux
both for host and guest sometimes that warning is chosen.
The tool trinity tries to avoid the syscall exit_group but that seems to be triggered nevertheless.

You are running out of available memory mappings on the host side.
mmap() fails because you have too much mappings installed.
See vm.max_map_count

Okay, there is definitely something wrong with mapping 0x100000 in UML.
We have seen something else with mmap() already...

Toralf Förster — 2013-04-02T19:50:58

Well,

fuzzying an UML (32 bit Gentoo Linux) system with SLUB for current git kernel 3.9-rc5-x gives
for the mentioned 4 syscalls very quickly a warning like the seen below.

What I (as usual) do not know, is, if these warnings are UML architecture specific
or if I should Cc: the LKML ?

Re: [uml-user] kmalloc returns NULL during module init

Han — 2013-03-22T00:21:44

Thanks.  I tried this but still have issues:

1) compile your kernel with DEBUG_INFO and FRAME_POINTER  -   I did this.
2) tell gdb to ignore SIGSEGV: handle SIGSEGV noprint nostop pass  -
I did this.

It crashed after making some progress:

(gdb) handle SIGSEGV pass nostop noprint

SIGSEGV       No        No      Yes             Segmentation fault

Program received signal SIGTERM, Terminated.

Should I ignore SIGTERM also ?
