[PATCH] PATCH: 1 line 2.6.18 bugfix: modpost-64bit-fix.patch

2006-08-15T19:53:09+00:00

There is a small but annoying bug in scripts/mod/file2alias.c which causes it to generate invalid aliases for input devices on 64 bit archs. This causes joydev.ko to not be automaticly loaded when inserting a joystick, resulting in a non working joystick (for the average user). In scripts/mod/file2alias.c is the following code for generating the input aliases: static void do_input(char *alias, kernel_ulong_t *arr, unsigned int min, unsigned int max) { unsigned int i; for (i = min; i < max; i++) if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG))) sprintf(alias + strlen(alias), "%X,*", i); } On 32 bits systems, this correctly generates "0,*" for the first alias, "8,*" for the second etc. However on 64 bits it generates: "0,*20,*" resp "8,*28,*" Notice how it adds 20 + first entry (hex) ! to the list of hex codes, which is 32 more then the first entry, thus is because the bit test above wraps at 32 bits instead of 64. scripts/mod/file2alias.c, line 379 reads: if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG))) That should be: if (arr[i / BITS_PER_LONG] & (1L << (i%BITS_PER_LONG))) Notice the added 'L' after the 1, otherwise that is an 32 bit int instead of a 64 bit long, and when that int gets shifted >= 32 times, appearantly the number by which to shift is wrapped at 5 bits ( % 32) causing it to test a bit 32 bits too low. The patch below makes the nescesarry 1 char change :) Signed-off-by: Hans de Goede Acked-by: Rusty Russell Signed-off-by: Greg Kroah-Hartman

kbuild: improve error from file2alias

2006-08-01T09:32:46+00:00

The original errormessage was just plain unreadable. Sample error message after this update (not for real - I provoked it): FATAL: drivers/net/s2io: sizeof(struct pci_device_id)=33 is not a modulo of the size of section __mod_pci_device_table=160. Fix definition of struct pci_device_id in mod_devicetable.h Before a warning was generated - this is now a fatal error. Signed-off-by: Sam Ravnborg

[PATCH] Input: add modalias support

2006-01-05T00:18:09+00:00

Here's the patch for modalias support for input classes. It uses comma-separated numbers, and doesn't describe all the potential keys (no module currently cares, and that would make the strings huge). The changes to input.h are to move the definitions needed by file2alias outside __KERNEL__. I chose not to move those definitions to mod_devicetable.h, because there are so many that it might break compile of something else in the kernel. The rest is fairly straightforward.
