2019-03-18	f620bee Browse files » pstore: improve error report for failed setup ... When setting ramoops record sizes, sometimes it's not clear which parameters contributed to the allocation failure. This adds a per-zone name and expands the failure reports.

	9788514 Browse files » pstore/ram: Do not use stack VLA for parity workspace ... Instead of using a stack VLA for the parity workspace, preallocate a memory region. The preallocation is done to keep from needing to perform allocations during crash dump writing, etc. This also fixes a missed release of librs on free.

	478035d Browse files » pstore: Make ramoops_init_przs generic for other prz arrays ... Currently ramoops_init_przs() is hard wired only for panic dump zone array. In preparation for the ftrace zone array (one zone per-cpu) and pmsg zone array, make the function more generic to be able to handle this case. Heavily based on similar work from Joel Fernandes.

	08c0102 Browse files » ramoops: use DT reserved-memory bindings ... Instead of a ramoops-specific node, use a child node of /reserved-memory. This requires that of_platform_device_create() be explicitly called for the node, though, since "/reserved-memory" does not have its own "compatible" property.

	a327b29 Browse files » pstore/ram: add Device Tree bindings ... ramoops is one of the remaining places where ARM vendors still rely on board-specific shims. Device Tree lets us replace those shims with generic code. These bindings mirror the ramoops module parameters, with two small differences: (1) dump_oops becomes an optional "no-dump-oops" property, since ramoops sets dump_oops=1 by default. (2) mem_type=1 becomes the more self-explanatory "unbuffered" property.

	1455e22 Browse files » fs: devfs: forbid truncation when cdev has no truncate operation ... When a cdev doesn't have a truncate callback then forbid truncation and fail with -EPERM. Before this we had always failed with -ENOSPC in this situation. We checked for f->fsdev->dev.num_resources being nonzero, but this check was absolutely meaningless. It goes back to ancient times when the resources of a device were automatically added to devfs. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 6 Feb 2019
	20eea93 Browse files » fs: do not call truncate for FILE_SIZE_STREAM sized files ... open_and_lseek() increases the file size when the file is opened in write mode and scrolled past the files end. This fails badly on /dev/mem because loff_t which we use for the file size is signed variable, which is used as an unsigned variable in /dev/mem. To catch this case do not try to truncate FILE_SIZE_STREAM sized files. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 6 Feb 2019

2019-02-04	d7c2384 Browse files » fs: Simplify new position calculation in lseek() ... All these checks are really testing is that resulting position is within [0; f->size] interval. Convert all of the custom checks into a signle one done after the switch statement to simplify the code. Note this change also disables the validity check for f->size == FILE_SIZE_STREAM and whence == SEEK_END, but lseek(stream_fd, offset, SEEK_END) wasn't a meaningful operation to begin with, so this shouldn't be a problem.
