From 5a958db311c416345a61b7bddc62a5c6c7112c7f Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 2 Oct 2012 11:36:31 -0700 Subject: [PATCH 001/221] make CONFIG_EXPERIMENTAL invisible and default This config item has not carried much meaning for a while now and is almost always enabled by default (especially in distro builds). As agreed during the Linux kernel summit, it should be removed. As a first step, remove it from being listed, and default it to on. Once it has been removed from all subsystem Kconfigs, it will be dropped entirely. For items that really are experimental, maintainers should use "default n", optionally include "(EXPERIMENTAL)" in the title, and add language to the help text indicating why the item should be considered experimental. For items that are dangerously experimental, the maintainer is encouraged to follow the above title recommendation, add stronger language to the help text, and optionally use (depending on the extent of the danger, from least to most dangerous): printk(), add_taint(TAINT_WARN), add_taint(TAINT_CRAP), WARN_ON(1), and CONFIG_BROKEN.

However, one issue that keeps popping up is its lack of a specific error code to determine which of the steps that it performs failed. Furthermore, while the function gives an example and suggests what error code to return on failure, a wide variety of error codes are used throughout the tree. In an attempt to fix these problems, this patch adds a new function that drivers can transition to. The devm_ioremap_resource() returns a pointer to the remapped I/O memory on success or an ERR_PTR() encoded error code on failure. Callers can check for failure using IS_ERR() and determine its cause by extracting the error code using PTR_ERR(). devm_request_and_ioremap() is implemented as a wrapper around the new API and return NULL on failure as before. This ensures that backwards compatibility is maintained until all users have been converted to the new API, at which point the old devm_request_and_ioremap() function should be removed. A semantic patch is included which can be used to convert from the old devm_request_and_ioremap() API to the new devm_ioremap_resource() API. Some non-trivial cases may require manual intervention, though.

The panic/reboot path has fixups that look up devices in pci_bus_type.

In two places (kernel/power/suspend_test.c, drivers/scsi/osd/osd_uld.c) this patch changes match callbacks to use const search data. The const is propagated to rtc_class_open() and power_supply_get_by_name() parameters. Note that there's a dev reference leak in suspend_test.c that's not touched in this patch.

This causes two problems. - If a console driver gets deferred, then it may not be ready when userspace starts. For example, if a uart depends on pinctrl, then the uart will get deferred and /dev/console will not be available - __init sections will be discarded before built-in drivers are probed. Strictly speaking, __init functions should not be called in a drivers __probe path, but there are a lot of drivers (console stuff again) that do anyway. In the past it was perfectly safe to do so because all built-in drivers got probed before the end of initcalls. This patch fixes the problem by forcing the first pass of the deferred list to complete at late_initcall time. This is late enough to catch the drivers that are known to have the above issues.
