* UBI: add dump_stack in checking codeArtem Bityutskiy2009-05-181-0/+1
| | | | | | | | I am experiencing an error in 'paranoid_check_volume()'. Add dump_stack() there to make it easier to identify the reasons of the error. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: fix races in I/O debugging checksArtem Bityutskiy2009-05-181-7/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When paranoid checs are enabled, the 'io_paral' test from the 'mtd-utils' package fails. The symptoms are: UBI error: paranoid_check_all_ff: flash region at PEB 3973:512, length 15872 does not contain all 0xFF bytes UBI error: paranoid_check_all_ff: paranoid check failed for PEB 3973 UBI: hex dump of the 512-16384 region It turned out to be a bug in the checking function. Suppose there are 2 tasks - A and B. Task A is the wear-levelling working ('wear_leveling_worker()'). It is reading the VID header to find which LEB this PEB belongs to. Say, task A is reading header of PEB X. Suppose PEB X is unmapped, and has no VID header. Task B is trying to write to PEB X. Task A: in 'ubi_io_read_vid_hdr()': reads the VID header from PEB X. The read data contain all 0xFF bytes. Task B: writes VID header and some data to PEB X Task A: assumes PEB X is empty, calls 'paranoid_check_all_ff()', which fails. The solution for this problem is to make 'paranoid_check_all_ff()' re-read the VID header, re-check it, and only if it is not there, check the rest. This now implemented by the 'paranoid_check_empty()' function. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* UBI: re-name volumes_mutex to device_mutexArtem Bityutskiy2009-05-185-23/+23
| | | | | | | The mutex essencially protects the entire UBI device, so the old @volumes_mutex name is a little misleading. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBI: remove redundant mutexArtem Bityutskiy2009-05-183-7/+2
| | | | | | | | | | The @mult_mutex does not serve any purpose. We already have @volumes_mutex and it is enough. The @volume mutex is pushed down to the 'ubi_rename_volumes()', because we want first to open all volumes in the exclusive mode, and then lock the mutex, just like all other ioctl's (remove, re-size, etc) do.

* UBI: fix resource de-allocationArtem Bityutskiy2009-01-201-3/+13
| | | | | | | | | | GregKH asked to fix UBI which has fake device release method. Indeed, we have to free UBI device description object from the release method, because otherwise we'll oops is someone opens a UBI device sysfs file, then the device is removed, and he reads the file. With this fix, he will get -ENODEV instead of an oops. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* UBI: add ioctl compatibilityArtem Bityutskiy2009-01-181-23/+57
| | | | | | | | | | | | | UBI ioctl's do not work when running 64-bit kernel and 32-bit user-land. Fix this by adding the compat_ioctl method. Also, UBI serializes all ioctls, so more than one ioctl at a time is not a problem. Amd UBI does not seem to depend on anything else, so use unlocked_ioctl instead of ioctl (no BKL needed).

This patch updates them to 64-bits but leaves the external API unchanged. Extending the external API is a separate issue for several reasons. First, no one needs it at the moment. Secondly, whether the implementation is done with IOCTLs, sysfs or both is still debated. Thirdly external API changes require the internal API to be accepted first. Note that although the MTD API will be able to support 64-bit device sizes, existing drivers do not and are not required to do so, although NAND base has been updated. In general, changing from 32-bit to 64-bit values cause little or no changes to the majority of the code with the following exceptions: - printk message formats - division and modulus of 64-bit values - NAND base support - 32-bit local variables used by mtdpart and mtdconcat - naughtily assuming one structure maps to another in MEMERASE ioctl Signed-off-by: Adrian Hunter <ext-adrian.hunter@nokia.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

|/ | | | | | | | | | | | | | | | | | | The 'ubi_io_read_vid_hdr()' and 'ubi_io_read_ec_hdr()' function have the 'verbose' argument which controls whether they should print a warning if the VID/EC header was not found or was corrupted. Some callers require the headers to be OK, and pass 1. Some allow a corrupted/not present header, and pass 0. if (UBI_IO_DEBUG) verbose = 1; And UBI_IO_DEBUG is 1 if CONFIG_MTD_UBI_DEBUG_MSG_BLD is true. So in this case the warning is printed all the time. This confuses people. Thus, do not print the messages as warnings if UBI_IO_DEBUG is true, but print them as debugging messages instead.

| | | | | | | | | | | | | | | | | | | | Before UBI got into mainline, there was a slight flash format change - we did not have sequence number support, then added it. We have carried full support of those ancient images till this moment. Now the support is removed, well, not fully removed. Now UBI will support only _clean_ old images, which were cleanly detached last time (just before kernel upgrade). This is most likely the case. But we will not support unclean ancient images. Surprisingly, this allows us to remove a big chunk of legacy code. And the same should be true for downgrading: clean images should downgrade fine, but unclean ones will not.
