3.2.42 without the grsecurity patches, and the same .config works fine.

Cheers

can you add this:

Code: Select all

printk("PAX: %pR\n", res);

into include/linux/ioport.h:resource_size() just before the return? this will probably produce quite a few more lines of logs, let's hope you can capture them. we'll need the line printed just before the overflow message.

looks like there's a real bug somewhere as this is an invalid range: 0x00100000-0x000fffff (start > end). now the question is where this bad range comes from. can you try to determine on a vanilla kernel what pci device reports or gets assigned such a memory range?

edit: try to enable CONFIG_PCI_DEBUG and see if it spits out something useful during boot.

Sorry, I can't find anything.
Nothing in lspci or dmesg suggest any device is given that range.
CONFIG_PCI_DEBUG likewise doesn't show anything like that, I've tried it with both vanilla and grsecurity patched kernels.

Hi,

This is actually a sort of 'me too' message since I also have this problem since 3.2.42. Sorry bout that...

Weird thing is I also have it on almost identical hardware. One of them works (1u server) and the other panics (blade). lspci gives almost the same output on both. Capturing kernel output will be difficult since I do not have a serial console set up on these servers.

Hi,

I have the same issue. Capturing kernel output will be difficult since I do not have a serial console connected to the servers.

Any way I can help?

I've added a similar printk() to a vanilla 3.2.43. It too spits out 0x00100000-0x000fffff, so grsecurity/PAX is just trying to protect me from a "fault".
However it seems that 0x00100000-0x000fffff isn't an unusual range to see, so as wrong as it seems this may not be a fault.
Google has many results for that range in relation to PCI devices (bridges mostly), many of which are years old too.

I'd try removing the check on resource_size/resource_size_t, but I'm so over my head I'd probably make it much worse!

can you guys try to add this somewhere at the beginning of kernel/resource.c:allocate_resource()

Code: Select all

printk("PAX: root:%pR new:%pR\n", root, new);dump_stack();

and send me the results (or just show here the log related to the bad range)? also i expect that the primary caller will be drivers/pci/bus.c:pci_bus_alloc_resource and it'd be nice if you could print out the pci bus info there but i don't know if there's a handy function for it or not.

Hi,

same problem here with the most recent grsecurity patch against kernel 3.2.43. In my case the memory regions are different (0x40000000-0x40007fff) and are apparently used by the VMware SVGA II adapter. The machine is a VM running under ESX 4 - Debian Wheezy. I enabled CONFIG_PCI_DEBUG, but it does not seem to print anything more than the stuff already shown here, unless I have to activate that somehow ?

Thanks in advance

can you post the kernel logs corresponding to this (also add the printk above please)? the range you show is a valid one, so i'm thinking it a different issue.

I added the printk and this is what is shows:

PAX: root:[mem 0x000a0000-0x000bffff] new:[0x00000000-0x00007fff pref]

Regarding the full output, I only got a screenshot right now, since I cannot capture the boot process at the moment

i'm afraid this doesn't show the error case, it's just normal looking ranges, and not the one you reported previously. and i'd also need the size overflow message. perhaps you can get a serial console to work even under vmware? it used to work fine in workstation at least.

Right, got a serial console attached, here is the full output booting up:
