2017-09-15pflash: Fix erase command for unaligned start addressSuraj Jitindar Singh1-1/+1
The erase_range() function handles erasing the flash for a given start address and length, and can handle an unaligned start address and length. However in the unaligned start address case we are incorrectly calculating the remaining size which can lead to incomplete erases. If we're going to update the remaining size based on what the start address was then we probably want to do that before we overide the origin start address. So rearrange the code so that this is indeed the case.

2017-09-04mambo: Add mambo socket programMichael Neuling2-0/+367
This adds a program that can be run inside a mambo simulator in linux userspace which enables TCP sockets to be proxied in and out of the simulator to the host. Unlike mambo bogusnet, it's requires no linux or skiboot specific drivers/infrastructure to run. eg. Run inside the simulator: - to forward host ssh connections to sim ssh server ./mambo-socket-proxy -h 10022 -s 22 Then connect to port 10022 on your host ssh -p 10022 localhost - to allow http proxy access from inside the sim to local http proxy ./mambo-socket-proxy -b proxy.mynetwork -h 3128 -s 3128 Multiple connections are supported.

2017-08-22external/pflash: Silence false positive Coverity CID 163739Cyril Bur1-0/+6
Several of the cases in the getopt loop take the optarg pointer and pass it to functions which will dereference it. There is currently no bug as all of these are marked to getopt as having a requirement argument so optarg will never be null. The rationale for this patch is firstly to silence coverity as it is fairly simple to do. More importantly having a brand new version of this Coverity error appear in the event of a future mistake with optional arguments to getopt will be useful.

New code that is very much pflash functionality was added in commit f2c87a3d2f6 "pflash option to retrieve PNOR partition flags". Unfortunately at the time there wasn't an easy way to test pflash.

The reason for this is that check targets for one tool will start to depend on other tools. For example, future pflash tests will rely on ffspart to generate pnors.

Recent work did some optimising which unfortunately removed some of the progress bars in pflash. It turns out that there's only one thing people prefer to correctly programmed flash chips, it is the ability to watch little equals characters go across their screens for potentially minutes. Personally I don't understand the appeal but I have received strongly worded requests for the reinstatement of the progress bars in pflash and I fear for the stability of our society if pflash doesn't promptly regain its most unimportant feature.

Currently all the flash details including the pointer to the blocklevel_device to access the flash is global.

2017-08-01external/pflash: Correct erase alignment checksCyril Bur1-27/+13
pflash should check the alignment of addresses and sizes when asked to erase. There are two possibilities: 1. The user has specified sizes manually in which case pflash should be as flexible as possible, blocklevel_smart_erase() permits this. To prevent possible mistakes pflash will require --force to perform a manual erase of unaligned sizes. 2. The user used -P to specify a partition, partitions aren't necessarily erase granule aligned anymore, blocklevel_smart_erase() can handle. In this it doesn't make sense to warn/error about misalignment since the misalignment is inherent to the FFS partition and not really user input.

2017-08-01libflash/libffs: Don't require 'part' size to be known by callersCyril Bur10-22/+15
Currently the FFS header/TOC generation code requires that consumers know the size of their TOC beforehand. While this may be advantageous in some circumstances if there are known limitations of other software. It should not be a requirement. Knowing the size of the FFS header/TOC partially breaks the abstraction since it would require consumers of the library to be aware of/have some idea of the on flash structure and size. Future work may introduce functions to force sizes but the default behaviour should be to calculate it behind the scenes. This patch also addresses an off by one issue in checking for TOC overflow.

2017-06-14mambo: Create multiple chips when we have multiple CPUsMichael Ellerman1-1/+11
Currently when we boot mambo with multiple CPUs, we create multiple CPU nodes in the device tree, and each claims to be on a separate chip. However we don't create multiple xscom nodes, which means skiboot only knows about a single chip, and all CPUs end up on it. At the moment mambo is not able to create multiple xscom controllers. We can create fake ones, just by faking the device tree up, but that seems uglier than this solution. So create a mambo-chip for each CPU other than 0, to tell skiboot we want a separate chip created. This then enables Linux to see multiple chips: smp: Brought up 2 nodes, 2 CPUs numa: Node 0 CPUs: 0 numa: Node 1 CPUs: 1 Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>

On mambo it's loaded at 0x80000000 and if you're unlucky skiboot can allocate over the top of it and corrupt the initramfs blob. There might be the downside that the kernel cannot re-use the initramfs memory since it's marked as reserved, but the kernel might also free it anyway.

For a start, the SSH daemon will only accept connections after a special incantation (which I also can't share), but you should put that in the ~/.skiboot_boot_tests file along with some other default login information we don't publicise too broadly (because Security Through Obscurity is *obviously* a good idea....)
