You guys are much quicker compiling kernels than I am :) Fabio, are you still seeing the same panic, just without the warnings? Or has the panic resolved itself as well?

Nothing.

If my reconstruction of what's going on is correct, the call chain here is do_path_lookup() <- kern_path() <- lookup_bdev() <- blkdev_get_by_path() <- mount_bdev() <- some_type.mount() <- mount_fs() <- vfs_kern_mount() <- do_new_mount() <- do_mount() <- sys_mount() <- do_mount_root() <- mount_block_root() <- mount_root().

I get stat("/dev/root") -> -2 stat("dev") -> -2 with the patch applied (+panic) and: stat("/dev/root") -> 0 stat("dev") -> 0 with the old version of do_path_lookup.

Wait a minute ... at this early stage of boot, I'm pretty sure we don't have a valid current->audit_context since we haven't fork'd anything. If the audit context was non-NULL garbage that might explain the panic ...

If the > audit context was non-NULL garbage that might explain the panic ... Could you try initializing the init_task's audit_context to NULL in the INIT_TASK macro in include/linux/init_task.h? Example: #define INIT_TASK(tsk) { .state = 0, .stack = &init_thread_info, ... .audit_context = NULL, ... }

If the > > audit context was non-NULL garbage that might explain the panic ... Not really - the panic is predicatable result of not finding /dev/root (hell, not even /dev there!) in mount_block_root(). > Could you try initializing the init_task's audit_context to NULL in the > INIT_TASK macro in include/linux/init_task.h? Missing fields in struct initializer are treated as zeroes. The shit hits the fan earlier - when we end up missing /dev. There are two places where it could've been created (depending on CONFIG_BLK_DEV_INITRD); sys_mkdir(collected, mode); in init/initramfs.c (line 353 in linux-next) and err = sys_mkdir((const char __user __force *) "/dev", 0755); in init/noinitramfs.c (line 32). The latter would've screamed on failure; could you printk of collected (%s), mode (%o) and return value (%d) in the former and see what happens? -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
